Also, the custom page size code did not use the ParamCustomPageSize attributes (STR #127) - The cupstestppd command did not list the conflicting options (STR #123) - The lpq command did not ensure that there was whitespace between the fields in the job listing (STR #117) - The German web templates had errors (STR #119) - The configure script didn't specify the static libraries properly when configuring with the --disable-shared option (STR #104) - The cups.list file used file dependencies for package formats other than portable, RPM, and Debian (STR #98) - cupsLangGet() didn't use its language cache (STR #97) - "lpq -P" would segfault instead of showing a usage message (STR #94) - Fixed compiler warnings in pdftops filter (STR #96) CHANGES IN CUPS V1.1.19rc5 - Jobs with banner pages that were printed to implicit classes would get double banner pages for each file/banner in the job (STR #68) - The mime.convs file was missing the filter definition for Windows BMP (image/x-bitmap) files (STR #85) - The scheduler allowed some READ-ONLY job attributes to be set, which could cause the scheduler to fail on the next restart (STR #82) - The lp and lpr commands did not report when the scheduler was not responding; instead, the user would incorrectly see a "no default destination" error (STR #70) - cupsLangGet() could fail on OSX due to a corrupt language preference (STR #78) - Added more checks for HTTP request timeouts. - The scheduler dropped the first non-alpha character after an open brace when doing attribute substitutions in banner pages (STR #77) - The scheduler child might send SIGUSR1 to the parent before the signal handler was installed; this didn't prevent the scheduler from starting but produced an annoying error message (STR #45) CHANGES IN CUPS V1.1.19rc4 - The lp command did not accept "-" for printing from the standard input as required by POSIX 1003.1 (STR #59) - Added the job-originating-host-name information for the page_log file documentation in the SAM (STR #31) - The German web interface templates did not use the right paths for job operations (STR #54) - The scheduler would consume all available CPU if started with a pending job in the queue (STR #35) - The polling daemon allocated an extra localization buffer but did not free it, causing cups-polld to eventually use all available memory (STR #40) CHANGES IN CUPS V1.1.19rc3 - The scheduler could get in an infinite loop cancelling jobs using "cancel -u user dest" (STR #48) - The "cancel -u user" command did nothing (it should cancel all jobs on all printers owned by the named user - STR #48) - The scheduler would write 0-length job control files (STR #46) - Updated the French man pages (translation provided by Gilles QUERRET) - The scheduler would delete all printers from printers.conf if a job was active when a HUP signal was handled (STR #47) - The cups-polld program would leak memory if it was unable to send browse packets to the loopback interface (STR #40) - The scheduler did not put the job-originating-host-name attribute in the job attributes group. - The text filter did not default to wrapping text as defined by the IPP implementation document. - Scan backends first, PPDs second (STR #37) - Updated the Netatalk documentation in the SAM (STR #38 and #39) - The test suite sent text files to a non-PS print queue, which requires ESP Ghostscript (provided separately). Now send the JPEG test file (STR #33) - The test suite did not show the estimated disk space requirements (STR #33) - The test suite did not set the MaxLogSize directive to 0 to prevent log file rotation (STR #33) - The test suite still setup the old CUPS Ghostscript symlinks (STR #33) - The pstops filter did not report the correct number of copies for the page_log file when printing collated copies to a printer that doesn't support them in hardware (STR #32) - cupsLangGet() needs to set the CTYPE locale to "C" (POSIX) to avoid erroneous tolower/toupper values (fix suggested by Bjoern Jacke) - Fixed a typo in the cups.list.in file. - Updated all of the Western European locales to default to ISO-8859-15 (for Euro support, suggested by Bjoern Jacke) - Updated the German message catalog (update provided by Bjoern Jacke) CHANGES IN CUPS V1.1.19rc2 - cupsLangGet() now sets the encoding field based on the trailing charset in the locale name, and doesn't look for a message catalog in a specific locale.charset directory. This fixes STR #26 and is more in line with the CUPS 1.2 implementation. - The configure script now aborts if the "ar" command or compilers cannot be found. - The static cupsimage library was not built by default. - The path for the "ln" command was hardcoded in Makedefs.in instead of being checked at configure time (STR #28). - Banner pages containing unescaped { characters would not work. - The printer-state-time collection attribute was encoded as an enumeration instead of an integer. - The printer-is-accepting-jobs collection attribute was was not added to the collection value. - The printer-state-sequence-number collection attribute was not added to the collection value. - Fixed typo and const mismatch in IPP backend. - Updated the man pages for the new configuration directives. - Updated the SAM for MacOS 10.2, the CUPS drivers for windows, the available LPD backend options, and the new configuration directives. - The imagetops filter didn't position images properly on the page (STR #18) - The configure script didn't add CPPFLAGS to the compiler options or LDFLAGS to the DSO options (STR #13) - The scheduler would try to write a debug log message when starting a job that contained a NULL string. Since not all versions of snprintf() support NULL string pointers this caused some problems (STR #20) - The testipp program now supports reading of IPP message files such as those used for the job history in /var/spool/cups. CHANGES IN CUPS V1.1.19rc1 - Added CUPS support files for Java, Perl, and PHP (located in the "scripting" subdirectory...) - The scheduler now supports fast-reloads of the cupsd.conf file when it is updated via HTTP. - The scheduler always changed the ownership of log files; it now only does so if they are not in the /dev directory (i.e. don't want to change the ownership and permissions of /dev/null...) - Added libpaper support (patch from Jeff Licquia) - Added a new istring() rule for MIME types files that does a case-insensitive comparison of strings. - The cups-lpd mini-daemon now sends jobs to the default queue when an empty queue name (or "lp" and there is no "lp" queue) is sent. - The scheduler now supports fax queues identified by a "*cupsFax: True" attribute in the PPD file. When a job can't be sent, it is held for 5 minutes by default while other jobs are attempted. The FaxRetryLimit and FaxRetryInterval directives control the number of retries and the time between retries. - The scheduler now preserves the default options of PPD files when modifying/upgrading an existing PPD file. When installing a new printer, the scheduler sets the default media size to Letter or A4 as appropriate for your locale. - The scheduler no longer limits the number of BrowseAddress, BrowsePoll, BrowseRelay, Listen, Port, SSLListen, and SSLPort directives to 10. - The scheduler now supports print files that have been compressed using gzip. - The scheduler used the stdio functions to read any job ticket information in a PostScript print job. Since some platforms limit the number of stdio files to 256, job ticket information was ignored when the server had a large number of clients connected to the system. - Filters and backends may now report the total number of pages ("PAGE: total NNN") to the scheduler. - The LPD backend now supports timeout and sanitize_title options (default to 300 and yes, respectively) and has some additional changes to reduce the chances of multiple copies being printed when only one copy was requested. - Fixed a polygon drawing bug in the HP-GL/2 filter. - Added a robots.txt file to the standard install to prevent search engines from indexing the CUPS server. - Added support for STATE: messages (printer-state-reasons), printer-state-history, and printer-state-time to the scheduler. - When using RunAsUser, the scheduler would initially start any previously queued (pending) jobs with RunAsUser disabled - all backends would be running as root. - If a backend failed for a printer, CUPS would incorrectly requeue the job for printing again. - Added support for IPP collections and files. - Added experimental support for generic CGI scripts and programs, Java, Perl, PHP, and Python to the scheduler. See the file "CGI.txt" for more information. - The CUPS API now supports HTTP cookies and the Expect: field. - The cancel command now correctly supports the "-u user" option to cancel all jobs for the named user. - The Purge-Jobs operation now supports the my-jobs boolean attribute and a new purge-jobs boolean attribute to control whether job history data is purged from the scheduler; the default is false for my-jobs and true for purge-jobs to match the original implementation. - The scheduler would not timeout printers when only using SLP browsing. - If the scheduler was unable to execute a filter, it would try to restart the job indefinitely until the filter could be executed. - When writing BSD printcap files, the scheduler now includes the rm and rp attributes, allowing the file to be exported to LPD clients. [Patch from Dominic Kubla] - The scheduler optimization to reference IPP attribute data instead of performing a full copy caused problems when the referenced data was deleted before it was sent. It now only references attributes that change only when the scheduler is restarted. The change also reduced the memory footprint of a printer object to 2k. - The scheduler now holds signals while logging messages to avoid potential deadlock issues when handling signals on Solaris 8. - The lpadmin command now allows printer access control by group name as well as user name. - "lpoptions -l" got in an infinite loop if no default printer was available. - The scheduler now logs the job-originating-host-name attribute in the page_log file, and uses "-" for any empty fields (patch from Dominik Kubla). - The pdftops filter now scales PDF pages within the printable area of the page. - The pstops filter didn't include the page-label and classification boxes when printing EPS or non- conformant PS files. - The imagetops filter didn't always correctly position the image on the page when printing in landscape orientation. - The ppdEmit() functions now support the RequiresPageRegion attribute when sending InputSlot and ManualFeed commands. - The PPD loading code now supports standard options outside of OpenUI/CloseUI as required by the PPD spec. - The cupstestppd program has been upgraded to provide a concise PASS/FAIL report, additional detailed conformance testing, and support for gzip'd PPD files. - The PPD loading code is now much more strict when loading a PPD file, and tracks more format errors. - The scheduler ignored child signals when gathering the list of available devices, when it should have been using the default signal handler. - The cupsEncodeOptions() function could encode an option with a NULL last string. - The socket backend could report the wrong number of backchannel bytes if an error occurred on the link. - The cups-polld program now only sleeps after getting all printers and classes. This allows for longer intervals without excessive delays before classes show up... - Added a new httpWait() function to support waiting for data for a specific number of milliseconds. - httpGets() now times out after 1 second on non-blocking HTTP connections. - The scheduler no longer accepts rangeOfInteger values that are out of order (e.g. 5-1) - The sides attribute was incorrectly sent as a name value; it is a keyword value. - The IPP backend now detects if the destination queue has gone away and reports an error. - The scheduler and HTTP API now allocate their select() sets to support larger numbers of clients on systems that support it. - The scheduler now sets the CFProcessPath environment variable under MacOS X. - The cupsLangDefault() function now uses the CoreFoundation localization API under MacOS X. - The httpSeparate() function didn't handle file URIs of the form "file:///path" properly. - The lpadmin command now supports a "protocol" option for specifying the binary communications protocol to use when printing binary PostScript data. - The scheduler did not properly parse the SystemGroup directive, so only the first group would be used. - Revamped how strings are stored in the scheduler, providing a substantial improvement in memory usage for systems with large numbers of printers. - The PostScript filter now supports binary PostScript files and files beginning with the PJL language escape sequence. - The PPD API now provides additional information from the PPD file. - The USB backend didn't compile on Solaris Intel. - The cupstestppd utility now supports the "-q" option (quiet) for use in scripts, etc. - Merged several weight-reducing changes into the CUPS baseline donated by Apple. - Added preliminary support for CDSA; patch provided by Apple. - Implicit classes are now created from identical printer classes on the network. - The lp command now supports a "-H restart" option to restart previously printed jobs. This functionality only works if you have enabled the PreserveJobFiles option. - The scheduler now supports URIs in HTTP request lines to conform to the HTTP/1.1 specification. - The time-at-xyz attributes were not recognized in banner files if prefixed by a question mark, e.g. "{?time-at-creation}". - Added support for pre-filtering application/pictwps files on MacOS clients before sending them to a server via IPP. - The scheduler now allows file:/dev/null device URIs even if FileDevices is set to No. - CUPS uses strerror() for hostname resolution errors, when it should have used hstrerror(). - The USB backend no longer tries to guess the serial number of a device from the USB devices file; this means that printers that don't report their serial numbers in the device ID string will not be individually selectable. - The pstops filter didn't handle page ranges properly when a page contained an embedded document. - Added a translation of the web interface to German. - When printing using the OutputOrder=Reverse option with duplexing, the output order is now truly reversed; the order of sub-pages when printing N-up is the same. - The pstops filter did not always output the extra blank page when printing a document with an odd number of pages with duplexing enabled. - The ippAddXYZ functions no longer allow the application to add less than 1 value. - Fixed a URL rewrite bug in the web interface - local access was sometimes redirected away from localhost... - The ppdOpen() functions could get in an infinite loop if the PPD file contained a keyword or text that was too large for the buffer. - Added preliminary support for GNU TLS; patch provided by Jeff Licquia. - Now timeout IPP attribute reads after 1 second inside an attribute definition. - Now timeout connections that have been shutdown (due to errors) after 30 seconds instead of the Timeout setting (300 seconds by default). This provides faster recovery from DoS attacks. - A denial-of-service attack warning message was being written to the log files by the scheduler for every detection. This caused a DoS of its own in some situations. The warning message is now written no more than once per minute. - Fixed the CIE colorspace support code in the image and PS RIPs. - The job-quota-period, job-page-limit, and job-k-limit attributes were not flagged as integers, so setting quotas would not work. - Added an additional response check in the scheduler to more quickly recover from denial-of-service attacks. - The cupstestppd file was incorrectly installed in the /usr/sbin directory instead of /usr/bin. - The EPM list file did not include the cupstestppd program or man page files. CHANGES IN CUPS V1.1.18 - Fixed a bug in the Set-Job-Attributes code in the scheduler that would cause it to crash or continuously write a job control file. - SECURITY FIX: The scheduler now provides a FileDevice directive to control whether new printers can be added using device URIs of the form "file:/filename". The default is to not allow printers with these device URIs. - The scheduler did not compute the cost of filters properly, nor did it choose a multi-filter solution with a lower cost than a single filter solution. - Now install CUPS PPD file test utility (cupstestppd) to support basic conformance testing of PPD files. - The scheduler now logs an error message when it sees a non-conforming PPD file. - Upgraded pdftops filter to Xpdf 2.01 with fixes for TrueType fonts. - Added a MaxClientsPerHost configuration directive to provide limited protection against Denial of Service attacks. - SECURITY FIX: Potential underflow/overflow bug in web interface. - SECURITY FIX: Race condition in certificate creation. - SECURITY FIX: Bad URIs in browse packets could be used to exploint the web interface underflow/overflow bug. - SECURITY FIX: Some types of Denial of Service attacks were not handled properly, so once the attack was over the scheduler did not close the connections immediately on all platforms. - SECURITY FIXES: Added integer overflow/underflow checks for all image formats. - The pstops filter didn't reset the showpage operator back to its original at the end of a job; this prevented the concatenation of documents (used primarily for CUPS 1.2...) - The cupsGetPPD() function didn't always set the cupsLastError() value when an error occurred. - The IPP media, output-bin, and sides attributes took precedence over the corresponding PPD options, which caused inconsistent behavior under MacOS X with some PPD files. - The cupsaddsmb utility specified the wrong number of arguments to the adddriver command when adding the Win9x PostScript drivers. - The web interface did not always report the correct error message. - The scheduler did not clear the POSIX signal action structure when waiting for the child to send it a SIGUSR1 signal; this could cause the signal handler not to be called properly, preventing the parent process from returning. CHANGES IN CUPS V1.1.17 - The "manual_copies" option did not work when the LPD backend had to retry a print job. - The image filters did not convert GIF images properly. - The RunAsUser option was incompatible with the new daemon-mode code in 1.1.16. - Fixed a problem with the Set-Job-Attributes and PostScript job ticket code in the scheduler - the "last" attribute pointer was never updated, which could cause the scheduler to crash when applying job ticket data. - Fixed a problem in the scheduler that caused it to continue processing HTTP requests on a connection after it was shutdown. - The scheduler now allows accounts authenticated via PAM to not have a corresponding UNIX account, but group membership still requires the account name to be listed in the UNIX group file(s)... - The scheduler used a fixed-size (16k) buffer for encoding job options for filters; it now dynamically allocates and expands the buffer as needed depending on the options that are sent in a job. - The pdftops filter didn't support all of the MacOS characters for MacRoman encoded fonts. - The cupsEncodeOptions() and cupsParseOptions() functions now conform to the grammer defined by the current draft of the PAPI specification. The main difference is that option=yes and option=no are no longer treated as boolean options. - The IPP backend didn't honor the encryption settings in /etc/cups/client.conf. - Fixed a potential bug in the HTTP code which was caused by servers sending the status line and newline(s) in separate packets. - User-defined classification strings are now printed verbatim - previously the classification box would be empty. - Re-added Spanish to the list of PPD languages that CUPS supports. - CUPS API library user and temp file updates for Windows. - The image filters did not properly handle grayscale printing of Sun Raster images. - The scheduler never reset the NumJobs variable before loading the job list (previously this only happened on a full start, so the problem was never apparent...) - The HTTP and IPP read/write code didn't handle EINTR (interrupted system call) errors. - When under high load, the scheduler could abort due to the wrong errno value after a select() call. This was caused by the child signal handler. - Added new load tests to the test target to verify that cupsd can handle hundreds of simultaneous jobs without error. - The Solaris USB backend now supports the new device URI syntax. - The ppdOpen*() functions now reset the numeric locale settings while loading a PPD file. - Fixed the libtool build rules. - The manpage make rules didn't use $(MAKE) and $(MFLAGS) for the language subdirectories. - Now set the LC_TIME locale category to get the properly localized time string. - Fixed a problem in the scheduler that would cause the web interface problems when adding, modifying, or configuring a printer or class. - The backends now ignore SIGPIPE so that failed job filters will not stop a print queue. - The lpstat command did not allow for destination lists ("lpstat -v printer1,printer2") - Fixed parsing of long filter status messages in the scheduler. - Added some startup performance enhancements to the scheduler so that the printer object information is regenerated fewer times and the MIME type database is not filled with lots of empty filters for raw/direct queues. - The LPD backend now sends the job title as the print filename. - Added support for variable sizes in the EPSON dot matrix printer drivers. This allows for pages as short as 1/2" (1 row of labels) and does not do an automatic form feed. - French translation updates. - The filters did not quote the page label string when embedding it in PostScript output. - The serial backend now enumerates serial ports under MacOS X. - The pdftops filter contained font rasterizer code that wasn't being used and that depended on X11. This code has been removed. CHANGES IN CUPS V1.1.16 - The cancel and lprm commands now both display an error message and return a non-zero exit status if an attempt is made to cancel a job on a non-existent printer. - The lpoptions command incorrectly complained if a request to delete a non-existent printer was made. - If the client.conf file defines an alternate server name, the "configure printer" action in the web interface might not work. - The lpstat command now supports a "-W" option so that you can display completed jobs as well as not-completed (pending) jobs. - The lp and lpr commands did not return an error when one or more files in a set of files for printing could not be printed. - The lp, lpadmin, and lpstat commands now consistently return with a non-zero exit status when an error occurs. - The scheduler would not accept print jobs sent to a stopped remote printer. - The texttops filter incorrectly converted the page numbers in the prettyprint header to double-byte characters when printing a non-Unicode text file. This caused an extra space to appear between each digit in the page number. - The scheduler did not use a case-insensitive comparison when adding filters for a printer. - Upgraded the pdftops filter to Xpdf 1.01. - The scheduler no longer passes the page-border and number-up-layout attributes to filters when printing banner pages. - The LPD backend now uses a 30-second timeout when sending commands and control files, and a 30-second timeout when retrieving responses from an LPD server. If a timeout occurs, it retries indefinitely. This helps to make LPD printing over VPNs work more reliably. - The USB backend now supports device URIs based on the printer serial number and/or model number under Linux. This avoids the "wrong device filename" problem when using more than one USB printer. - Now just shutdown the receiving end of a client connection when sending an error that requires the server to disconnect from the client afterwards. This fixes a problem when doing remote administration with encryption enabled. - The scheduler did not send a printer-state-message attribute if the string was empty; it now always sends this attribute. This caused the printer message to be displayed for other printers in the web interface. - The LPD backend now supports a "manual_copies" option, e.g.: "lpd://server/queue?manual_copies=no", in order to handle copies for raw jobs to printers that don't implement the LPD protocol properly... - The "mirror" option was not being handled by the PostScript or image filters. - Updated the cupsaddsmb command to support the new CUPS driver for Windows NT/2k/XP. - Filter status lines longer than 1023 characters could cause the scheduler to get into an infinite loop. - The scheduler didn't reset the job state to pending when modifying an active printer. - Now limit the maximum number of recursion steps when searching for a filter for a job, in case a user defines a circular filter rule. - The PostScript filter would embed an invalid requirements comment in some cases. - Added support for embedded job tickets in PostScript files. - The PostScript filter now detects EPS files and should better handle printing EPS files. - The cancel command now ignores a trailing destination name when cancelling a specific job ID (Solaris compatibility). - The scheduler now rejects jobs with copies outside the range of 1 to MaxCopies, inclusive. - Added new MaxCopies directive to set the maximum number of copies that a user can request. - The scheduler didn't block signals while it processed others and when it forked processes. - The scheduler checked for new jobs to print when stopping a job. This caused jobs to restart before a shutdown. - Updated the CUPS startup script to better support different timezones and to support the RedHat/Mandrake init script functions, if available. - The scheduler did not properly handle backslashes in banner files; it incorrectly assumed that "\c" should always be replaced by "c", instead of only looking for "\{" and replacing it by "{". - The texttops filter didn't handle prettyprint=no. - The text and HP-GL/2 filters didn't check for other common duplex option names like cupsMarkOptions() did. - "lpoptions -x printer" no longer clears the "default printer" status of the printer. - cupsTempFd() now stops trying to create a temporary file after 1000 tries, and aborts on any error other than EEXIST. This should prevent lp/lpr hangs due to a bad or missing temporary directory. - The lpadmin command did not send the right URI to the scheduler when setting options on classes. This caused a client-error-bad-request error. - The CUPS API convenience functions would attempt to connect to the remote server name in a "printer@server" printer name instead of dealing with the default (usually local) server. Aside from causing user confusion, the remote server name might not be resolved properly, causing further problems. - "lp -q" would cause the "lp" command to segfault, as the program would try to print the option letter that caused the error using the wrong index into the command-line; bugfix from Debian. - Fixed a minor inconsistancy in the encoding of boolean attributes from printer options in cupsEncodeOptions(). - Added a FilterNice directive which sets the priority of job filter processes that are run by the scheduler. - Added Solaris x86 USB printer support. - The USB backend now reports both the ulpt and unlpt devices under *BSD. - The "lpstat -o" command would truncate the "printer-jobid" string if it was longer than 21 characters. - The PJL-based MIME type rules now look in the first 1024 bytes instead of just the first 512 bytes to find the language mode. - The image file types are now listed explicitly in the mime.convs file so that additional image file formats do not use the standard CUPS image filters by default. - Updated the Software Programmers Manual to include all of the CUPS API functions. - ppdOpen*() no longer sorts choices for an option. - The web interface now enforces constraints in PPD files when configuring a printer. - When stopping a printer, the scheduler didn't set the printer state before stopping the current job. - The cupsaddsmb utility now lists all data files for Win9x and WinMe clients when installing that Windows driver. - Jobs submitted to a class now bounce immediately to the next available printer rather than waiting until that printer is available. - Filters and backends now also get the CLASS environment variable set when a job is printed to a printer class instead of a normal printer. - Added French translations of the web interface, CUPS Overview, Software Administrators Manual, and Software Users Manual contributed by Marian REYT-LLABRES. - Added several "hint" messages for common configuration problems that are stored in the error_log file. - httpSeparate() now unquotes %xx characters in the username:password field of a URI. - When starting the scheduler in daemon mode, the parent process now waits for the child to signal it is ready to accept connections. - Added -F option to cupsd to run cupsd in the foreground but detach from the controlling terminal and current directory. - The scheduler did not reload jobs when receiving a HUP signal; this would cause problems since the pointers into the file type database would no longer be valid for existing jobs. - The scheduler did not save the network interface list update time, thus no caching of the network data was actually provided. - Updated the SuSE PAM configuration file. - The LPD backend now supports a "reserve" option and no longer reserves a priviledged port by default. - The cupsaddsmb command now continues past printers that do not have a PPD file to export. - The lpstat command didn't treat printer names as case-insensitive. - The lpstat command now reports the printer location attribute with "lpstat -l -p". - Fixed a bug in the vsnprintf() emulation function, which was used on old versions of HP-UX, IRIX, and Solaris. - The number-up option was incorrectly being used when printing banner pages. - Added support for Greek and Slovak PPD files. - CUPS now supports printer names containing any printable character, e.g. "123-abc", "foo-bar", etc. - The null filter was not supported in mime.convs due to a bug in the filter validation code. - Changes in the default printer and printer attributes were not always reflected in the generated printcap file. - Implicit classes did not inherit the location or description from member printers. - The httpGetHostByName() function did not handle hostnames that started with a number. - Updated the filters to use the %cupsRotation comment instead of %%Orientation to auto-rotate pages, since the use of %%Orientation is inconsistent. - Added the RootCertDuration directive to control how often the root authentication certificate is updated. - Increased the size of the IPP write buffer to 32k to allow for larger attribute values and to provide more efficient output of large numbers of attributes. - The polling daemon now retries the initial connection to the remote server; this fixes a problem when the remote server is unavailable when the scheduler starts up... - The scheduler didn't validate Digest users against the system group(s), so Digest and BasicDigest authentication didn't work for administration operations. - The scheduler now passes the SHLIB_PATH environment variable to child processes (HP-UX shared libraries) - The scheduler now maps accesses from the loopback interface to "localhost". - The cups-lpd mini-daemon sent a status code byte in response to queue state commands, but those commands only return textual data. CHANGES IN CUPS V1.1.15-1 - The lpc and lprm sources didn't include the CUPS string function header, which is required on systems that don't have their own snprintf() function. - The French manpage Makefile tried to install the language subdirectories when it (obviously) didn't have to. CHANGES IN CUPS V1.1.15 - Updated the CUPS license agreement for the new MacOS license exception. - The printer-info attribute now defaults to the printer name if no value has been set. - ppdOpen() and friends now add an "Auto" InputSlot option if none is provided to automatically select the correct tray. - Updated the ppdEmit() and ppdEmitFd() functions to (re)mark the correct PageSize or PageRegion option depending on the selected ManualFeed or InputSlot options. - ppdEmitFd() didn't handle custom page sizes. - Darwin uses instead of . - The jobs.cgi web interface now handles all job operations, allowing the administrator to allow "job administrators" or operators to manage jobs (but not queues) on the server. - The cupsDoFileRequest() function now checks if the filename passed into the function is a directory, and returns the IPP_NOT_POSSIBLE error if so. - New SCSI printer backend. - Cleaned up handling of locales with trailing character set definitions. - Fixed handling of invalid PPD attributes inside OpenUI/CloseUI. - Fixed a problem with SSL and the job, printer, and admin CGIs on ports other than 443. - The scheduler didn't handle AuthClass properly. - Added French translation of man pages. - Updated the text filter to support the const_cast, dynamic_cast, and static_cast keywords in ISO C++. - Now use strlcat() and strlcpy() (or emulation functions) for easier string/buffer protection. - The auto-generated printcap/printers.conf files now have a small comment header explaining where the file comes from... - The PostScript filter now supports 6, 9, and 16-up output, as well as new page-border and number-up-layout options. - The lpoptions command didn't set options properly when using the default printer. - Added ConfigFilePerm and LogFilePerm directives. - Increased maximum size of MIME types to IPP_MAX_NAME to allow for longer printer names. - No longer create remote printers when loading job history data. - The printer-make-and-model attribute wasn't set when the PPD file didn't contain a NickName attribute. - Now handle PPD files with translation strings longer than 80 bytes - they are truncated if they go over... - The scheduler didn't handle signals until after it loaded the configuration files the first time; this caused problems on some installations that would restart the scheduler as the system booted into run level 3. - Now throttle broadcasts like we do for polling. - Fixed a bug in the reading of PPD files using CR's instead of CR LF's or LF's. - The scheduler would crash if cupsd.conf contained a BrowseProtocols line with no protocols listed. - The HTML job operation templates now link back to the destination printer or class. - The serial backend now detects USB serial devices. - The LPD mini-daemon (cups-lpd) now passes the job-originating-host-name attribute to the scheduler (cupsd). - Updated the IPP backend to reconnect after downgrading from IPP/1.1 to 1.0, and when sending requests to HP JetDirect interfaces that don't support HTTP Keep-Alive like they should. - Now pass NLSPATH and DYLD_LIBRARY_PATH environment variables, if defined, to CGI and job processes. - Removed the pstoraster filter (based on GNU Ghostscript 5.50) and now provide the raster "driver" and patch file necessary to use the current GNU Ghostscript 7.05 release. - Removed unnecessary fonts and updated the Courier and Symbol fonts to the latest versions to better support non-ISOLatin1 text. - The text filter now always embeds the Courier and Symbol fonts to ensure that they contain the full set of glyphs. - The lp and lpr commands now only override the SIGINT handler if it is not being ignored (patch from Robert Ambrose for some interactive software that catches SIGINT and will gracefully cancel the print...) - The PostScript image filter (imagetops) now supports printing CMYK images using the CMYK colorspace. - The image filters now support CMYK JPEG files, and correctly handles the inverted files from Photoshop (which seems to save RGBW data, not CMYK...) - Added a "check" target to the top-level makefile to conform with GNU standards (same as "test"). - The IPP code didn't always map the POSIX locale "C" to the proper IPP language code. - The cupsaddsmb program was updated to use the setdriver command instead of addprinter. - Banner pages were not handled properly for implicit classes. - When tunneling to a remote system using SSH, the printer URIs for local printers on the remote system did not reflect the correct port number. - The Allow, Deny, BrowseAllow, BrowseDeny, and BrowseAddress directives now support the network interface names "@LOCAL" and "@IF(name)" for access control and browsing based on the current interface addresses instead of fixed names or IP addresses. - The texttops filter did not properly recognize the "nowrap" (wrap=false) option. - The InstallableOptions group name in a PPD file is now translated separately (CUPS_MSG_OPTIONS_INSTALLED) so that UIs can accurately detect the presence of this group. - The scheduler no longer keeps job history data for remote printers on the client (just on the server.) - The parallel and USB backends now retry if the backend detects that the printer is not connected to the system (rather than stopping the queue...) - The network backends now retry if the backend detects that the printer is not connected to the network or is unreachable (rather than stopping the queue...) - The cupsGetDests() function no longer lists options and instances for printers that no longer exist. - The scheduler now converts the document language to the correct LANG string. - The cupsaddsmb program now supports alternative CUPS and SAMBA server names. - The PostScript filter now supports the Orientation comment and rotates the page as needed automatically. - Revamped the makefiles slightly to use automatically generated dependencies. - Build fixes for OS X. - The TIFF reading code depended on the newest version of libtiff; now conditionally compile that portion of the loader. - The PPD code now decodes all JCL options in the JCLSetup group, not just those options that start with the prefix "JCL". - The backends now read print data using the read() system call to ensure that the current page is printed while the next page is being processed. - The pdftops filter did not support shading type 3 (radial fill) for the "sh" operator. - The cups-polld program now throttles the local broadcasts of polled printers and classes so that the local system is not overwhelmed with hundreds of printers and classes all at once. - Updated the serial backend to support 230,400 baud for the Linux PPC port. - The cupsGetJobs() function wouldn't report completed jobs that did not have a document-format attribute value. - The cupsEncodeOptions() function now maintains a table of known boolean and numeric options, and encodes all other options as strings. - Now add a newline before the end-of-page code in the PostScript filter; this fixes a problem with files that don't end with a newline. - The image filters looked for the "orientation" option instead of the correctly named "orientation-requested" option. - The cupsEncodeOptions() function now handles mixed integers and ranges. - New translation guide for developers to provide native language support for CUPS. CHANGES IN CUPS V1.1.14 - The ippRead() function did not verify that the attribute name length or string with language value was not larger than the read buffer. - The scheduler set the signal handlers before loading the configuration files the first time; this prevented the RunAsUser directive from blocking server reloads. - Added Swedish message catalog. - The parallel backend now recognizes the /dev/printers device directory under Linux 2.4.x. - MacOS X fixes. - The cupsaddsmb utility sent the server name after the user information when executing the rpcclient program. This caused problems with some versions of SAMBA 2.2.x. - The IPP backend did not pass the requesting user name when checking on the print job status. This prevented it from waiting for the job to complete when communicating with some IPP implementations that require it. CHANGES IN CUPS V1.1.13 - The lpstat command did not report jobs submitted to regular printer classes. - The texttops filter didn't use sufficient precision when positioning text with some values of cpi and lpi. This could cause the alignment of text to stray. - cupsGetDests() didn't merge the options from the /etc/cups/lpoptions file with ~/.lpoptions - options in ~/.lpoptions overrode them completely. - Added support for KOI8-R and KOI8-U character sets, and added several Russian message catalogs. - The scheduler put the wrong timezone offset in the log files (e.g. +0500 instead of -0500 for EST...) - The scheduler did not ignore trailing whitespace in *.convs files. - The scheduler now forces all processes to exit (kill -9) when it is stopped. This prevents parallel and USB devices from running in the background after cupsd goes away. - The cupsParseOptions() function didn't skip trailing whitespace after quoted values. - More changes to support CUPS on OS/2. - Added Simplified Chinese message catalog. - Added PAM support for IRIX. - The cupsGetPPD() function didn't remove the @server portion of the printer name, and since it would connect immediately to the remote server instead of the local server, the printer would not be found. - Classification and page labels were not rotated to match the page orientation. - Now set the TCP "no delay" option on network connections to improve performance/response time. - Improved the IRIX printing tools support with patches from Andrea Suatoni. - Added a new PrintcapGUI directive to specify the GUI option panel program to use for the IRIX printing tools support. - The cupsGetDests() function did not check to see if a user-defined default printer (set via lpoptions) still existed. - The pstops filter no longer assumes that the default dictionary is writable when doing N-up processing. - The pstops filter now supports printing N-up with the page-set option. - The imagetoraster filter now supports direct printing of CMYK image data without conversion/correction. - The IPP backend now reports printer state/error conditions when possible (toner low, media empty, etc.) - The lpstat command now supports the (undocumented) IRIX -l option ("-lprintername") for a compact job listing for a printer. - The lpstat command now includes printer date/time information in the output (always Jan 01 00:00) to make third-party tools happy. - The text filter now supports non-integer cpi and lpi values. - The Margins field in the CUPS raster header was not initialized by the pstoraster filter. - Added --with-optim="flags" option to configure script. - Updated the Italian message translations. - Updated the cups.list file to install the correct files. - The pstoraster filter accessed the third element of a 2 element array. - The scheduler did not setup a status pipe for polling processes, so error messages went to whatever file descriptor 2 was pointing to when they were started. - The httpMD5Final() function didn't put a colon between the password and nonce strings. - The pstops filter did not default to Binary data for "%%BeginData:". - The pstops filter did not stop processing when a line containing a CTRL-D is seen. - The scheduler no longer replaces the JobSheets values from the printers.conf and classes.conf files with the classification level, if set. This way the original banner settings are preserved when classification levels are changed or turned off. - The serial backend didn't drain the output queue, nor did it restore the original settings. - Updated the default system group under MacOS X. - If no SystemGroup was defined in cupsd.conf, the system default group was not used. - The cups-lpd mini-daemon now supports LPD clients that send multiple control files. - httpConnectEncrypt() now always uses encryption for connections on port 443, since port 443 is reserved for the "https" scheme. - Group authentication via certificates did not work from the web interface for accounts other than "root". - The serial port backend did not clear the OPOST option, which could cause problems with some printers. - The cups-lpd mini-daemon didn't lookup the client IP address properly. - The parallel backend now identifies the polled and interrupt-driven devices under *BSD. - The scheduler allowed the "always" encryption mode inside a Location, which is not valid. - The CUPS startup script now checks for the timezone information under Linux. - Now also map the sides attribute to the JCLDuplex option (if present) in PPD files. - Updated pdftops to Xpdf 0.93a. - Added support for MD5 passwords under Slackware. - Added new AuthType BasicDigest that does Basic authentication using the MD5 password file managed by the lppasswd command. - The banner page attribute substitution code now retains {name} sequences in banner files when the named attribute is undefined. Use {?name} to conditionally substitute an IPP attribute. - The scheduler now ensures that the ServerRoot directory and configuration files are owned by and writable by the User and Group in cupsd.conf. - The USB backend now lists all USB printer devices regardless of whether a printer is connected or not. This allows new USB printers to be connected without restarting cupsd. - Added some more minor performance tweeks to the IPP protocol code to reduce copying and array indexing. - The cupsaddsmb utility now uses the -c option with smbclient and rpcclient to avoid the read length limit for commands on the standard input. - Added an include file to the CRD handling code in pstoraster so that it would compile properly on 64-bit pointer platforms... CHANGES IN CUPS V1.1.12 - Added "Polish" to the list of known languages for PPD files. - Added missing directory definition to cups-config. - The CUPS-Move-Job operation did not set the destination type for the new destination. - The CUPS-Add-Printer operation did not support the allow=all or deny=none values to clear the per-user printer ACLs. - The SetPrinterAttrs() function did not handle invalid PPD files that were missing the required NickName attribute. It now looks for NickName, ModelName, and then substitutes the string "Bad PPD File" for the printer-make-and-model attribute. CHANGES IN CUPS V1.1.11 - Added support for embedded TrueType fonts in PDF files. - Added support for PostScript functions in PDF files. - Added new "cupsaddsmb" utility for exporting CUPS printer drivers to SAMBA/Windows clients. - Added preliminary support for Darwin/MacOS X. - The CUPS-Add-Printer operation no longer allows arbitrary scheme names in device URIs to be used - it now restricts the available schemes to those found in the device list (lpinfo -m). - The ippRead() and ipp_read_file() functions could not handle more than IPP_MAX_VALUES (100) values in a 1setOf attribute. These functions have been updated to dynamically allocate more memory as needed, and the IPP_MAX_VALUES constant now represents the allocation increment. [this caused some versions of the GIMP-print drivers to fail since the number of media options exceeded 100...] - The scheduler could crash when BrowseShortNames was set to "No". - The scheduler did not prevent MaxClients from being set to 0, which could cause the scheduler to go in an infinite loop when accepting a request. - Made some performance optimizations in the ippRead() functions to make IPP request/response processing faster. - The accept/reject/enable/disable command did not support properly support the "-h" or default server name. - The scheduler did not save the quota configuration when the job-quota-period attribute was set to 0. - The LPDEST and PRINTER environment variables did not support printer instances. - The text filter now handles more types of boldface and underline formatting. - The cupsTempFd() function did not fail if the temporary directory did not exist; this would cause it to loop indefinitely instead of returning an error (-1). - Stopping (disabling) a printer class did not stop jobs from printing to printers in that class. - The cupsGetDests() function was sending the requested-attributes attribute as a name instead of a keyword; this caused a serious performance problem on slower systems since more information had to be transferred from server to client. - The web interfaces did not always quote < and & in things like the job title. This had the potential for browser-based security violations (on the browser's machine); bug report from SuSE. - The scheduler now treats unauthenticated usernames as case-insensitive when doing quota and allow/deny processing. - The lp command sent the "request ID is ..." message to stderr instead of stdout... - The PostScript filter (pstops) now handles EPS files, adding a showpage command to the files as needed. - The configure script checked for the header file before the JPEG libraries; since the JPEG headers can define HAVE_STDLIB_H, the configure check would cause the JPEG check to fail on some systems. - The scheduler now supports localized banner files, using the subdirectory approach, e.g. the "es" subdirectory under /usr/share/cups/banners is used for the Spanish banner files. - Updated the scheduler so it knows the correct language abbreviation to use for all supported PPD LanguageVersion values. The new code also supports country codes as well, so "English-GB" maps to the "en_GB" locale. - The cups-lpd mini-daemon did not support anonymous printing (no username specified). While the username is REQUIRED by RFC-1179, MacOS clients do not send the REQUIRED username information when printing via LPD. - Added many warning and informational messages to cups-lpd where they were missing. - Added Czech message file contributed by SuSE. - The cups-lpd mini-daemon now returns a non-zero status if an invalid destination or job ID is provided. - The scheduler did not honor the KeepAlive setting in cupsd.conf. - Increased the size of the file read/write buffers to 32k. - *BSD static library creation fixes. - Use mkstemps() instead of tmpnam() in pdftops whenever possible. - Added httpGetHostByName() function as a wrapper around gethostbyname() - some implementations of this function do not support IP addresses (e.g. MacOS X.) - Added casts to all printf's of file lengths, since there is currently no standard way of formatting long long values. - The client filename field was not cleared in all instances, resulting in old form data being submitted to CGIs. - The httpConnect*() functions now try all available addresses for a host when connecting for the first time. - The pstoraster filter would "lose" all drawing commands when the PageSize was set but the printer bitmap was not reallocated. This was most noticeable with the output from StarOffice 6 beta and would result in a blank page being output... - The IPP backend was sending a PAGE comment even when printing the output from a filter (it should only send page comments when printing files directly...) - The pdftops filter didn't properly map glyph names of embedded Asian TrueType fonts. - Changed the CUPS startup script to look for a program named "cupsd", not just any program with "cupsd" in the name (this caused the apcupsd UPS monitoring daemon to be stopped/restarted...) - The CUPS-Move-Job operation did not change the internal destination name for held jobs, so moved (but held) jobs would still show up as queued on the original destination. - The cups-polld program didn't send the requested-attributes attribute in the CUPS-Get-Printers and CUPS-Get-Classes requests, which made it use more CPU and bandwidth than required. - The scheduler and CUPS API incorrectly added a job-sheets-default attribute for remote printers. This caused banner pages to be omitted from client system prints. CHANGES IN CUPS V1.1.10-1 - Minor fixes to the filter, systemv, and template makefiles to install files properly. CHANGES IN CUPS V1.1.10 - Added a driver for DYMO label printers. - Added new ClassifyOverride directive to allow users to override the classification of individual jobs. - Added new BrowseProtocols directive to control which browse protocols are used (currently CUPS and SLP). - Added SLPv2 support (thanks to Matt Peterson for contributing the initial implementation for CUPS.) - Adding a raw printer on a remote CUPS server now correctly redirects PPD file requests to the remote server. - The serial backend now limits writes to 1/10th second worth of data to avoid buffer overflows with some types of flow control. - The scheduler did not properly process PUT requests, so configuration files could not be uploaded to the server. - The scheduler did not strip trailing whitespace on lines in the configuration files. - The httpWrite() function did not transition the PUT request to the HTTP_STATUS state to get the status from the server. - The scheduler did not properly handle trailing null ("-") filters when testing a driver that sent data to the file: pseudo-backend. - The IPP backend now only sends a document-format of "application/vnd.cups-raw" when printing to another CUPS server using a local printer driver or interface script. Previously the job's document format was used, which was incorrect. - The lpadmin command didn't use the ppd-name attribute with the -m option; this prevented the use of the "raw" model from the command-line. - The pstoraster filter output draft (1-bit) 6-color output in the wrong order; this resulted in yellow being printed instead of black on Stylus Photo printers. - The pdftops filter did not have the Japanese and Chinese text support compiled into it. - The IPP and AppSocket backends did not clear the "waiting for print job to complete" status message, which caused some confusion... :) - The serial backend now opens the port in "no delay" mode to avoid DCD detection problems with some OS's. CHANGES IN CUPS V1.1.9-1 - The configure script did not substitute the correct user and group names. - The configure script did not use the full path to the install-sh script when it was used. - The pstoraster filter did not correctly support DuplexTumble mode for printers that used flip duplexing. - The cups.list.in file was missing from the distribution. - The New DeskJet series driver did not use the correct OrderDependency for the Duplex option. - Use read() instead of fread() to read piped print files in lpr/lp. This avoids a bug in the HP-UX 10.20 fread() function. - Updated the pstoraster filter to use the MIPS_FIXADE system call under IRIX to fix bus error problems on R12000 processors (Ghostscript is not 64-bit clean...) - Some Xerox PPD files (most notably the Phaser 790) have illegal whitespace in the option keyword in the OpenUI line. This caused the PageRegion option to not be recognized properly for the Phaser 790. CHANGES IN CUPS V1.1.9 - Revamped the configure script to use a modular approach for the various tests. - Added --with-openssl-* options to properly reference the OpenSSL libraries in DSOs. - Added --with-cups-user and --with-cups-group options to specify the default user and group for CUPS. - Added AIX shared library support. - Added AIX device discovery for the serial and parallel ports. - Now use install program or script to install directories, files, and symlinks. - Updated pstops filter to use strict handling of EPS files embedded in a PostScript document. The %%EOF handling in 1.1.8 caused some dvips files not to print. - Fixed yet another memory allocation bug in pstoraster that would cause it to crash. This fix also ensures that all memory allocations are done on (at least) a 64-bit boundary. - Fixed Digest authentication - httpGetSubField() didn't skip the Digest keyword. - The scheduler did not properly handle Digest authentication with the new multiple-group support. - The scheduler did not allow usernames that were not in the UNIX password file to be used for Digest authentication from passwd.md5. - The scheduler could not scan PPD files that only used a carriage return (i.e. MacOS PPD files); the new code is also about 40% faster, so servers with thousands of PPD files should start much faster now. - The scheduler now stores the PPD file size and modification times in the ppds.dat file, so it can now incrementally update the PPD database from the model directory, resulting in significantly faster startup times. - The lpinfo command did not return a non-zero status code if an error occurred. - Fixed a bug in the scheduler's UpdateJob() function. Basically, all jobs shared the same status buffer, and the "buffer start" pointer could point to 1 byte before the beginning of the buffer. The new implementation uses a separate buffer for each job and eliminates the buffer start bug. - The IPP backend would send N copies of a document if the receiving device didn't support the copies attribute, even if the upstream driver already added the necessary commands to generate the copies. This was most noticeable with HP printers where N * N copies would come out instead of N. - The PostScript filter (pstops) did not properly handle duplex printing on inkjet printers that provide this option. Copies would be put on the front and back sides of the duplexed page, and the filter did not output an even number of pages. - The backends always caught SIGTERM after they connected to the printer. This prevented raw jobs from being cancelled early. - The cupsSetDests() function now removes any printers, instances, and options that are not defined by the user or server. This should prevent old system-wide options from being used in individual user accounts. - Updated the EPSON printer driver and added PPDs for the newer EPSON Stylus printers that only support the "ESC i" graphics command. - The lpadmin command didn't allow you to add remote printers to a local class. - The lpadmin command didn't allow you to set the options (quotas, etc.) for a class. - The scheduler did not load or save the job-sheets-default attribute for classes. - The scheduler did not automatically recreate remote printers that were part of a class. - It was possible for a printer class to list the same printer more than once. - The scheduler now makes a backup copy of classes.conf and printers.conf before writing the new file. - The lppasswd program incorrectly asked for a new password when deleting an existing MD5 password account. - The scheduler did not match "/printers/name.ppd" against a location of "/printers/name". - The client code did not always handle HTTP encryption upgrades properly. - The client code now caches the last Digest password so it can retry using a new resource path or nonce value, which are included in the MD5 sum sent to the server. This should eliminate unnecessary password prompts when using Digest authentication. - The lppasswd command didn't have a man page. - Updated the PJL detection rules to allow the universal escape to occur anywhere in the first 128 bytes of the file. - The cups-polld program would poll servers continuously with no delay if there was an error contacting the server. - The IPP backend would send an empty job-name or requesting-user-name attribute if the corresponding job attribute was an empty string. While this is allowed by the IPP specification, some HP JetDirect implementations return a client-error-bad-request error if an empty name attribute value is received. The new code only sends these attributes if they are not the empty string. - At least some versions of the HP JetDirect firmware do not correctly implement IPP. Added additional checks to the IPP backend to eliminate extra, unsupported attributes which should normally be ignored by a compliant IPP device. - The scheduler did not copy the complete list of supported file types into the document-format-supported attribute. This caused clients to not send the local file type (such as application/vnd.cups-raw for raw print files) and the corresponding bad output in some cases. - The scheduler did not fully copy attributes from a set-job-attributes request - string attributes were only referenced, which could cause cupsd to crash or behave irratically. - The lp command didn't send the right value for the job-hold-until attribute when "-H resume" was specified. - The IPP backend now returns as soon as a job is completed or reported as "pending-held". - Added new ImplicitAnyClasses and HideImplicitMembers directives to the cupsd.conf file to make implicit classes more usable/transparent to the user. - Clients can now (with the appropriate authentication) retrieve and update the server configuration files using HTTP GET and PUT requests. - The web interface didn't allow you to modify the location or description of the printer. - The pdftops filter now uses its own temporary file function to work with PDF files using LZW compression (which use the uncompress program or gunzip) - The SystemGroup directive now supports specification of multiple groups. - Added new Include directive to cupsd.conf, a la Apache. - Added new pseudo-driver/PPD called "raw" that can be used to create/convert a raw queue. This also allows raw queues to be created in the web interface. - The pdftops filter didn't handle image objects that used JPEG and Flate compression together. - The pstops filter counted pages wrong when using the N-up and even/odd printing options. This prevented the page-ranges option from working properly. - Added another fix to pstoraster for a bus error condition caused by a lack of parenthesis in the Ghostscript code. - Added new "natural-scaling" option which scales the natural size of the image (percent of natural image size instead of percent of page size.) - The lppasswd program is now setuid to the CUPS user instead of root. - The PPD functions did not allow for PPD files that defined the page sizes and margins before the page size options. - The mime.types file now checks for the PJL "LANGUAGE = Postscript" command for PostScript files. - The scheduler did not truncate file: output files. - The PPD file reading code did not handle options with raw quotes (") in the human-readable names. - The pdftops filter now remaps the space character when (bad) PDF files contain a .notdef glyph for the space character. CHANGES IN CUPS V1.1.8 - Updated spec file to generate separate cups-pstoraster package for pstoraster. - The spec file wasn't setting LOGDIR in the install. - The scheduler might restart a stopped printer after stopping a print job. Thanks to Florent Guiliani for finding this bug! - The init script showed run level 0 for the Red Hat chkconfig program. This is incorrect because Red Hat doesn't use run level 0 for shutdown scripts. - The IPP backend did not handle the client-error-not-found error when checking the status of the job that was sent. This caused remote queues to stop on client machines when the server had job history disabled. - Added httpConnectEncrypt() function to avoid performance penalty for setting up encrypted connections initially. - Use httpConnectEncrypt() in all client apps and in the CUPS API to ensure consistent usage of encryption throughout. - Jobs weren't queued to remote classes (fix from Richard Begg.) - AIX changes from Richard Begg. - Fixed the pstops fix for GNOME output - no longer use the page numbers in the %%Page: comment since GNOME puts a filename instead (!?@!#?!). There is still an issue with N-up printing since GNOME defines its fonts in the first page instead of the document setup section (pages must be independent according to the DSC spec) People with GNOME printing problems should consult bug #54489... - The imagetops filter produced PAGE: messages when generating PostScript for a non-PostScript printer (only affects page-label and Classification options.) - The updated pdftops filter was looking for an options file called xpdf.conf instead of pdftops.conf. CHANGES IN CUPS V1.1.7 - Configuration script changes, including new "--with-docdir=/dir" option to relocate CUPS documentation and web content according to your favorite version of the FHS. - Documentation updates for encryption, SLP, etc. - New Software Test Plan and automated test script to test CUPS prior to installation. - All scheduler configuration files are now case insensitive to match Apache. - Added support for Apache ListenBackLog, Require, Satisfy, , , and LimitRequestSize directives. - Added support for all Apache log levels... - Added support for "double" HostNameLookups. - Added new "RunAsUser" directive to support non-root configurations on the standard (priviledged) ports. - Added support for non-root invocation of the lpd backend (does no reserve a priviledged port, which might not work with some LPD servers...) - Added new PrintcapFormat directive to control the output format of the printcap file (BSD or Solaris formats are supported at present.) - The CUPS directory service routines now handle ECONNREFUSED errors gracefully rather than shutting all browsing off. - ippErrorString() now returns the recommended error messages from the IPP/1.1 Model and Semantics document. - Fixed a minor IPP compliance issue with responses to requests without the attributes-charset or attributes-natural-language attributes. - Sun fix: need httpFlush() call for chunked IPP requests in cupsDoFileRequest(). - httpConnect() now looks up "localhost" by name and by address (127.0.0.1) for users the go to the trouble of removing the required localhost entry in /etc/hosts or on their DNS server... - Added support for Linux 2.4.x devfs parallel port filenames (/dev/parallel/N). - cupsDo[File]Request() and cupsGetPPD() no longer block trying to reconnect to a crashed or inaccessable server. - Added new ppdEmitJCL() function to better handle PJL commands from PPD files. - A bug in UpdateJob() would cause the scheduler to consume 100% CPU until another request was submitted. - The cancel command did not support the "-" option to cancel all jobs on all printers. - The cancel and lprm commands did not support cancelling the next/current job in the queue. - The pdftops and pstoraster filters were using unsafe temporary file functions; while this is not a problem in normal configurations (the CUPS temporary directory is restricted), they now use the cupsTempFd() function. - The mime.types file was missing the recognition rule for Sun Raster images. - The admin CGI was passing a printer make string to ippSetCGIVars() that was being replaced in that function. - "lpoptions -l" would resave the options... - The EPSON drivers now send the "end packet mode" command when printing to USB devices. - The scheduler initialized certificates before loading the cupsd.conf file. - The scheduler used /dev/random to collect random data, which could block if insufficient entropy information had been collected by the kernel. Now use /dev/urandom. - Fixed a bug in the whitespace skipping code in httpGetSubField(). - The LPD backend now supports a new "order" option: "lpd://server/queue?order=control,data" (default) and "lpd://server/queue?order=data,control". - The scheduler enforced a 30 second timeout on all clients regardless of the Timeout directive and if a CGI was currently running. - cupsParseOptions() now sets boolean options to option=true or option=false. - The "percent complete" calculations in the LPD backend could overflow on large files, causing the percentage to wrap to 0 every 40MB or so. - Fixed a memory reallocation bug in pstoraster that could cause it to crash. - The LPD backend now sanitizes the job title to avoid potential problems on remote LPD servers. - The lp command did not send the requesting-user-name attribute when altering a job. - The pstops filter did not handle PostScript files with lines longer than 8191 bytes. - The scheduler no longer uses inet_addr() to convert IP addresses in dot format (mmm.nnn.ooo.ppp) to the 32-bit format, since it will not work for IPv6 addresses. - New "Classification" directive to force labeling of the current classification on each page. - New "page-label" attribute to add per-page labels ("For Official Use Only", "Draft", etc.) - The scheduler now sets the HTTPS environment variable for CGI programs when a client connects using encryption. - Fixed a recursion bug in the scheduler that could cause cupsd to crash when a printer was removed. - The LPDEST and PRINTER environment variables didn't support instances. - Dropped the "file" backend from the device list that is reported, since it is only available for *testing* and should never be used in a production environment. The file: device can still be used, but it won't show up in the list of devices from lpinfo or the web interface. - Added support for /dev/lpa# parallel ports under *BSD. - Added META variables to the CGI header template to prevent caching of the results. - Fixed an unaligned memory buffer for the pstoraster clist states; this caused bus errors for some combinations of printers, drivers, and options. - Re-added black reduction for colorful colors; this helps to prevent dark colors from getting desaturated. (only used when converting RGB to CMYK) - Added two new directives - MaxJobsPerPrinter and MaxJobsPerUser - to allow an administrator to set the maximum number of pending jobs in a queue or submitted by a user. - The scheduler no longer stops a printer if it can't create the status pipe or run the filters or backend. This will allow heavily loaded servers to service clients or start print jobs as the load allows. - Fixed a bug in the Set-Job-Attributes code that could crash the scheduler (patch from Martin Zielinski) - cupsSetDests() did not quote option values with embedded spaces. - Added support for the Enable-Printer and Disable-Printer extension operations (same as CUPS-Accept-Jobs and CUPS-Reject-Jobs.) - The AppSocket and IPP backends now wait for the print job to be finished before exiting; this should prevent the loss of print jobs with older JetDirect firmware and make consecutive print jobs print faster. - The BMP loading code did not handle resolution values of 0. This is a problem with BMP image files produced by the GIMP. - The HTTP Upgrade code (upgrade to TLS encryption) bypassed the authentication checks. - The HTTP Upgrade code did not send a 426 status code to the client and end the current request. This caused a race condition between the client and server for the upgrade to TLS. - Fixed a bug in the EOF and Trailer detection code in the pstops filter. - The imagetoraster filter did not add the margins to the custom page size in the raster header. - The imagetops filter did not adjust the custom page size to the size of the printed image. - The imagetops filter did not include DSC comments which are required by some printers. - The imagetops filter did not insert newlines in Base85 encoded output, causing files to contain lines longer than 255 characters (violation of the DSC). - Added support for the DeskJet 900 series duplexer and CRET color modes in the HP driver. - Added support for PPD-defined margins in the HP driver. - Fixed the debugging output from pstoraster - the font list was not terminated by a newline. - Some versions of the HP-UX pam_unix authentication module apparently do not pass the appdata_ptr argument to the conversation function, preventing the scheduler from authenticating users using PAM under HP-UX. A workaround using a static variable has been added to address this problem. - Fixed a bug in the scheduler SortPrinters() function that could cause printers to disappear or the scheduler to crash when adding a printer. - Changed the pstops filter to not do per-page filtering if the file does not conform to at least version 3.0 of the document structuring conventions. This seems to "fix" printing with broken apps. - The image filters did not handle older TIFF files that lacked the samples-per-pixel and bits-per-pixel tags. - Added new cupsGetJobs() and cupsFreeJobs() functions to manage print jobs. - cupsEncodeOptions() would encode names of 0 length and cupsAddOption() and cupsParseOptions() would add names of 0 length. - The scheduler might block waiting for status messages after starting a new print job. Thanks to Florent Guiliani for finding this bug! CHANGES IN CUPS V1.1.6-3 - The configure script put the JPEG library before the TIFF library; this caused problems in some configurations since the TIFF library also supports JPEG compression of TIFF images. - Updated the configure script and makefiles to handle admin man pages with the "1m" extension (HP-UX, IRIX, Solaris, Tru64) and in odd directories (IRIX) - The updated cupsTempFile() function did not return the filename when called with a filename buffer of NULL (previously it used a static buffer.) - FreeBSD uses /dev/unlptN, but NetBSD and OpenBSD use /dev/ulptN. - DeletePrinter() didn't remove the printer from any classes it was a member of. - DeletePrinterFromClass() didn't preserve the implicit status of a class. - DeletePrinterFromClasses() didn't remove printers from implicit classes. - StartJob() didn't send the job-sheets, job-priority, and job-hold-until attributes to remote printers. - LoadAllJobs() was looking for job-sheets-completed instead of job-media-sheets-completed. This would prevent accumulation of page data after a restart of the scheduler. - The pstops and imagetops filters now generate copies using the appropriate method for a Level 1, 2, or 3 printer since some Level 2/3 printers don't support the /#copies variable anymore. - The man page for cups-lpd did not mention the "-o" option. - The IPP backend didn't handle version-not-supported errors and revert to IPP/1.0 (previously it only checked for a bad-request error) - Caldera fix: lpc now reports unimplemented commands as unimplemented, not invalid. - Caldera fix: lpq didn't recognize BSD lpq "-a" option. - Caldera fix: lpr didn't recognize BSD lpr "-1", "-2", "-3", "-4", "-q", or "-U" options. - RedHat fixes: patches to GNU Ghostscript - SuSE fix: temp file creation patch to GNU Ghostscript (pstoraster). - SuSE fix: remove cgi-bin/abort.c and cgi-bin/email.c, which are not used. - SuSE fix: missing NULL check in cgi_initialize_post(). - SuSE fix: potential buffer overflows in cgi_initialize_string(). - SuSE fix: potential buffer overflows in ippSetCGIVars() - SuSE fix: more NULL checks in ppdOpen(); also make sure that all memory is freed on error to avoid memory leaks. - SuSE fix: Exit from child if setgid() or setuid() fails. - SuSE fix: Added setgroups() calls after setgid() and setuid() calls. - SuSE fix: potential buffer overflows in httpEncode64() calls. - SuSE fix: potential buffer overflows in httpSeparate() - SuSE fix: potential buffer overflows in ippWrite() for bad input. - SuSE fix: potential nul skip in ppd_decode() for missing hex digits. CHANGES IN CUPS V1.1.6-2 - Added changes to support NetBSD startup scripts. - Added separate compiler options for pstoraster (Ghostscript) to avoid compiler-induced errors from Ghostscript's twisted code. - The mime.types file contained syntax errors. - Updated the *BSD USB device filenames to use the /dev/unlptN files so that the USB device is not reset prior to printing (causes print corruption on many printers) - Added new cupsTempFd() function to avoid serious security bug in glibc fopen() function. The glibc fopen() function unlinks a file before creating it, which opens up possible symlink attacks. - Now reject 0-length names in add-printer and add-class requests. - Fix for pstoraster when ZLIB is not available. - cupsGetPPD() didn't reconnect when a HTTP connection was lost. - SuSE fix: httpConnect() didn't check that the value from gethostbyname() was a valid IPv4 address. - SuSE fix: httpConnect() didn't allow file descriptor 0 to be used for a socket. - SuSE fix: ippRead() didn't confirm that all values in a set were numeric or string types. - SuSE fix: lppasswd race condition fixes. - SuSE fix: directive names could overflow buffer when reading *.conf files. - SuSE fix: HEAD requests for PPD files did not use the same logic as GET requests. - SuSE fix: possible buffer overflow when adding /index.html to requested directory name. - SuSE fix: possible buffer overflow when converting IPP attributes to string options for filters. - SuSE fix: creating file: device output with mode 0666 instead of mode 0600. - SuSE fix: creating job info files with mode 0640 instead of 0600. - SuSE fix: don't rely on snprintf() for including system name in log filenames. - SuSE fix: add bounds checking when copying quoted and hex strings. CHANGES IN CUPS V1.1.6-1 - Added configure check for getting the correct strftime() format string; %c is not Y2k safe, and %KC and NULL are not universally supported. CHANGES IN CUPS V1.1.6 - Fixed another possible DoS attack in httpGets() - Added check for "LANGUAGE = PCL" and "LANGUAGE = POSTSCRIPT" in mime.types. - Resolution options were not being passed into the filter programs properly. - The default compiler options for GCC no longer include "-g3", which apparently is deprecated in newer versions of GCC. - CheckJobs() could cause cupsd to crash if a job is cancelled in StartJob(). - The printers.conf and classes.conf files are now written with restricted permissions. - The round-robin algorithm used by FindAvailablePrinter() had problems; fixes contributed by Joel Fredrikson. - If LoadAllJobs() is unable to determine the file type of a print job, assume "application/vnd.cups-raw". - The web interface now provides a job_printer_name value for any corresponding job_printer_uri value. - The cups-lpd mini-daemon now logs the client address and hostname as well as all commands and errors in the syslog file. - The IPP backend now detects the supported file formats and only specifies the document format if it is supported. This makes IPP printing to network print servers and cards more reliable without affecting the capabilities of CUPS servers. - The time_at_xyz attributes are now converted to human- readable dates and times for the web interfaces. - The HP and EPSON sample drivers now correctly catch signals and eject the current page when a job is cancelled. - Fixed bug in CGI code - did not ignore control characters (e.g. newlines) in form data. This caused sporatic web interface problems. - The file type logging code in the scheduler referenced the optional document-format attribute; the new code uses the resolved MIME type instead. - The client.conf parsing code now removes trailing whitespace. - The MaxJobs directive was being treated as a boolean instead of an integer. - The scheduler would not timeout remote printers if BrowseInterval was set to 0. - The lpadmin command now supports setting of options and user-level access control. - Added "-E" option to all printing commands to force encryption. - The client code did not consume the response to the OPTIONS request when switching to secure mode. - The scheduler did not output a Content-Length field when responding to an OPTIONS request. - Added documentation on using cups-lpd with xinetd to the man page. - The socket backend now starts retries at 5 seconds and increases the interval to 30 seconds. This should provide faster printing when multiple jobs/files are queued for a printer. - The filters and backends no longer buffer output to stderr. This should provide much more accurate status reporting. CHANGES IN CUPS V1.1.5-2 - Fixed configure check for OpenSSL to work with RSA code. - Added configure check for , and use this check in backend/serial.c. - Updated configure script handling of data, configuration, and state directories to use datadir, sysconfdir, and localstatedir variables. - NetBSD uses different serial port filenames than FreeBSD and OpenBSD. - The pdftops filter didn't need some X-specific files. - The scheduler makefile doesn't do a chown anymore when installing (cupsd did this automatically on startup anyways) CHANGES IN CUPS V1.1.5-1 - There was a typo in the top-level Makefile - The top-level Makefile did not install an init script for run level 5. - The configure script did not add the "crypto" library when checking for the OpenSSL library. - The OKIDATA PPD files were missing. - The config.h.in file defined the wrong version number. - The serial backend did not define "funky_hex" under *BSD. - Updated the Visual C++ project files and some of the CUPS API sources to compile under Windows again. CHANGES IN CUPS V1.1.5 - Security updates - new default configuration does not broadcast printer information and only allows access from the local system. - EXPERIMENTAL encryption support - CUPS now optionally supports TLS/SSL encryption via the OpenSSL library. - Documentation updates. - Makefile/configure script updates. - The RPM spec file didn't work out-of-the-box under RedHat or Mandrake. - Minor code cleanup to remove extraneous compiler warnings. - cupsTempFile() was using %p for the temporary filename; this should have been %08x (just 8 digit hex) - Deleting a printer with active print jobs would still crash the server. - ippWrite() and ipp_write_file() didn't send the correct value length for name-with-language and text-with-language attributes. - Updated IPP code to support copied strings (that should not be freed); this provides slightly more efficient IPP server performance. - Updated PDF filter to Xpdf 0.91. - httpGets() could go into an infinite loop if a line longer than the input buffer size was sent by a client. This could be used in a Denial-of-Service attack. - The lpstat and CUPS API functions now request only the data required when getting the list of printer or class information. This should improve performance with large numbers of printers on slower machines. - The scheduler was always enforcing the FilterLimit, even if FilterLimit was set to 0. - Updated the Linux USB backend to support Mandrake's /dev/usb/usblp# filenames. - The PRINTER and LPDEST environment variables did not override the lpoptions default printer. - The PPD read functions incorrectly included trailing characters (usually whitespace) after quoted string attributes. - The multiple-document-handling attribute handling code did not check for the correct value for collated copies (separate-documents-uncollated-copies). - The EPSON driver did not work with OKIDATA printers in EPSON emulation mode (needed change-emulation command) - The HP-GL/2 filter did not scale the plot properly in scale mode 2. - Added PPD files for 9-pin and 24-pin OKIDATA printers. - The httpSeparate() function didn't handle passwords that started with a number. - ippDelete() could free the character set string multiple times in name-with-language and text-with-language attributes. - The scheduler would access freed memory right after freeing it (for debug messages); these parts of the code have been reordered to avoid this situation which was causing sporatic errors and crashes. - The ppdClose() function didn't free all of the strings in the ppd_file_t structure. - The LoadAllJobs() function in the scheduler did not close the spool directory. - Changed all sprintf's that use string formats to snprintf's, even if the destination buffer is larger than the source string(s); this protects against buffer overflows caused outside of CUPS... - Changed all strcpy's to strncpy's between local and global variables, even if the destination buffer is larger than the source string; this protects against buffer overflows caused outside of CUPS... - The CUPS certificate functions didn't use the CUPS_SERVERROOT environment variable when set. - The directory services code was copying instead of comparing the remote printer info, resulting in unnecessary updates of the printer attributes for remote printers. - Added new mime.types rules to allow automatic raw printing of PCL and ESC/P files; PJL headers are parsed to differentiate between PostScript and PCL job files. This should eliminate a lot of the reports of SAMBA printing problems due to the missing "-oraw" or "-l" options. - The mimeLoadType() function didn't handle the 3-argument contains() function. - The LoadPPDs() function in the scheduler didn't properly set the alloc_ppds variable or handle a PPD database containing 0 printers. - The scheduler FindAvailablePrinter() function didn't use the same queuing logic as the CheckJobs() function. This caused classes to stall if a remote printer was always busy. - Jobs are now assigned to printers in a class round-robin style. This should prevent the first server in the class from bearing the brunt of the jobs. - The scheduler's LoadAllJobs() function didn't always restore remote printers for queued jobs on startup. - The serial backend didn't support the higher baud rates with the old termios interface. It now supports 57600 and 115200 baud. - The serial backend now supports different types of flow control; previously it ignored the flow=XYZ option in the device URI. - The serial backend now supports DTR/DSR flow control, which is popular on dot-matrix printers (access with "flow=dtrdsr" in the device URI) - Added new job-originating-host-name attribute for jobs. The new attribute provides the hostname or IP address of the machine that submitted the job. - The set-job-attributes code no longer allows read-only job attributes to be changed. - Expanded the click area for the navigation bar in the web interface. - Updated the lp and cancel commands to support all of the Solaris print options (some are simply ignored since they do not map) - Updated the scheduler to limit the number of file descriptors to the maximum select() set size. This was causing problems on Solaris systems where the max FD count was increased beyond 1024. - The scheduler's LoadDevices() function was getting interrupted by the SIGCHLD signal handler; now ignore child signals while loading devices. - Added quota and allow/deny user support for printers and classes. - Removed black/CMY adjustment code from the PS and image file RIPs; it was interfering with some CUPS driver dithering code. - The lpc program stopped listing the queue statuses after the first active printer. - The cups-lpd program used an output format that the Solaris printing system did not understand. - Updated the lpq program to use the Solaris format except under Tru64 UNIX. - Some DEC PPD files incorrectly use "Off" for the null value in UI constraints. Added "Off" to the list of accepted null values. - Changed the *BSD define constants to __*BSD__ in all of the backends. - Added support for "lpstat printername", which is an undocumented feature in Solaris. - The HP-GL/2 filter now only sets the plot size if it is set in the plot file. - The lpmove command wasn't sending the requesting user name, causing it to always fail. - Updated the cupsTempFile() code to use GetTempPath() under Windows. - The cups-lpd mini-daemon didn't limit the number of data files accepted, didn't use cupsTempFile(), didn't handle control file job information in any order, and didn't free job options after printing a file. - The scheduler copy_banner() function did not explicitly set the owner and permissions of the banner files, which could prevent the banner pages from printing on some systems. - The lpstat program wasn't listing remote classes. - The scheduler did not verify that the printer-uri attribute was specified in all requests that required it. CHANGES IN CUPS v1.1.4 - Makefile and configure script fixes. - **** Changed the default Printcap setting **** to /etc/printcap. There are just too many people asking why application XYZ doesn't see their printers! - The web admin interface now displays an error if it can't get the list of printer drivers from cupsd. - The IPP backend was putting the copies option before the other job options were set. This caused the IPP request to contain attribute groups in the wrong order, which prevented remote printing. - Added checks in scheduler to free memory used for IPP requests and language information when closing a client connection. - Fixed the duplex option in the HP LaserJet driver. It should now work with all LaserJet printers (and compatibles) - The add-printer web interface didn't initialize the "old info" data pointer, which caused random crashes on many OS's. - Fixed many page sizes defined in the Level 1 compatibility file "gs_statd.ps" to match reality. - Fixed another bug in the setpagedevice "code" in Ghostscript. It should now accept all standard Adobe attributes on all platforms. - Fixed pstoraster so that it reallocates memory for color depth changes as well as size/resolution changes. This removes an ordering constraint on the color, page size, and resolution options in PPD files. - The IPP backend didn't use the job's character set when the destination printer supported it. This caused problems when printing text files to other CUPS servers. - Updated the logic used to determine when to rebuild the PPD file database. The scheduler now checks the dates and the number of PPD files (was just checking the dates.) - Updated the ippSetCGIVars() function (used by the web interfaces) to only filter valid string values. - The PostScript filter was scaling 2-up pages incorrectly. This caused the edges of some pages to be clipped. CHANGES IN CUPS v1.1.3 - Makefile fixes. - RPM spec file changes. - Documentation updates. - Enabled pstoraster debug messages for everything (only logged when LogLevel set to "debug"...) - Changed the Input/OutputAttributes fix in pstoraster so that it works on all platforms. - The HP-GL/2 filter didn't set the right green color value in encoded polylines or text. - Updated the "fitplot" code to handle plot sizes specified as "PSwidth,length" and "PSlength,width". - Updated the Linux parallel and USB backends to open the device files prior to looking in /proc for autoprobe info. This makes sure that loadable device driver modules are in fact loaded... - Added new FilterLimit directive to limit the number of processing jobs/filters on a system. - set-job-attributes didn't change the job-state to held/pending when the job-hold-until attribute was specified. - set-job-attributes didn't save the new job attributes. - Now change the "requesting-user-name" attribute in requests from remote systems to "remroot" when an unauthenticated "root" user is sent. This can be changed using the new RemoteRoot directive in cupsd.conf. - The cancel-job, hold-job, release-job, and restart-job operations didn't log the authenticated username. - The cups-lpd mini-daemon now checks for a document-format option before forcing raw mode with filter mode 'l'. - The cups-lpd mini-daemon now supports "-o" options on the command-line (passed by inetd) to set global defaults for all print queues. - The pstops filter assumed that a file with a Trailer comment would also have an EOF comment. - Added new cupsSetPasswordCB(), cupsSetServer(), cupsSetUser(), and ippSetPort() functions to better support client applications (especially GUIs...) - The CUPS-add-class and CUPS-add-printer operations didn't reset the printer-name attribute on remote print queues that had to be renamed when a local printer was defined with the same name. - The lpoptions command now supports a "-r" option to remove options for a printer or instance. - The lpadmin and admin.cgi programs no longer allow class and printer names to begin with a number; this caused the command-line utilities to become confused. - The Linux USB backend now looks for both the parallel and usblp driver names in the device list. - Added a new FontPath directive to cupsd.conf, and also a "--with-fontpath" option for the configure script to specify alternate font paths for pstoraster. - The CUPS-move-job operation didn't update the job-printer-uri attribute. - The scheduler only looked up printers and classes by name in IPP requests, instead of using the full URI. This caused problems with KUPS and friends with remote printers. - The scheduler now handles better localization of hostnames (e.g. server is host.foo.com, remote is host.subfoo.foo.com, localized is not host.subfoo...) - The scheduler logging functions now use a common log file checking/rotation function (courtesy of Crutcher Dunnavant at Red Hat) - The scheduler could accept more client connections than it allocated for if more than one Port or Listen line was present in cupsd.conf. - Other minor scheduler performance tweeks. - The lpq and lprm commands didn't support the default printer set using lpoptions. - The lpoptions command now supports a "-l" option to list the printer-specific options and their current settings. - The web printer and class lists now show a link to the default printer or class at the top of the page. - The text filter now supports pretty printing of shell and perl scripts as well as C/C++ source files. - The top and bottom margins were reversed for landscape text printing. - The lpq and lprm commands didn't understand printer instances. - The scheduler only selected on the first 100 file descriptors instead of the maximum file descriptor limit. - The scheduler client, listener, and mainline functions now share code to disable and enable monitoring for new client connections. - The imagetoraster filter didn't support all of the required pagedevice parameters. - The serial backend now checks for 100 serial ports under Linux. - The scheduler used sscanf() to pull out the remote printer location, description, and make/model strings, but if any of these options was empty then sscanf() would stop processing. - Added "debug2" log level to provide a little less verbose debugging information at the "debug" level. - The scheduler would crash if you stopped a printer that was currently printing a job. - The scheduler incorrectly allowed jobs in the cancelled, aborted, or completed state to be cancelled. - The image filters did not load TIFF images properly for bottom-to-top and right-to-left orientations. - Added new cupsEncodeOptions() function to encode CUPS options as IPP job attributes. - The IPP backend, LPD mini-daemon, client commands, and CUPS API did not properly encode multiple option values separated by commas. - Added new scheduler malloc logging in debug mode (provides summary of total arena size, allocated, and free bytes once a minute) - The EPM-based distributions didn't install the correct symlinks for a few man pages. - Fixed a memory leak in the scheduler - wasn't freeing old filters when deleting or renaming printers. - The scheduler now queries the primary IP address for the name of the server and maps any incoming requests from that address to the server name. This fixes web admin mapping problems from server.domain.com to localhost. - The web printer modify interface now remembers the previous device and driver settings (except for serial ports.) - The job-k-octets attribute is now stored as part of the job attributes; this preserves the information after a job is completed when job file history is turned off. - Dropped option sub-group parsing code for the moment, since many Xerox PPD files abuse this feature in PPD files and don't follow the hierarchy rules. - Added new wrapper code around options so that duplex options for some HP printers don't prevent prints. - Added support for Digital UNIX/Tru64 UNIX/OSF/1 format for "lpstat -v" output. - Now show the URI for remote printers instead of /dev/null in "lpstat -v" output. - Creating classes and adding printers to a class with the lpadmin command didn't work. - The banner pages and test page should now format correctly in both portrait and landscape orientations. - Updated banner page substitution so that { can appear by itself without quoting. CHANGES IN CUPS v1.1.2 - Makefile/configure fixes - RPM spec file and EPM list file fixes - The cupsTempFile() function now uses a different algorithm for generating temp files and "reserves" them to avoid possible security exploitation. - Now use /dev/random (if available) to seed the random number generator for certificates. - The /var/spool/cups and /var/spool/cups/tmp directories were incorrectly owned by root; they are now owned by the filter user, typically "lp". - The scheduler now resets the permissions on the spool and temp directories as needed to match the filter user. - Now expose ppdCollect() as an externally callable function. - The image filters now support filtering from the standard input. - The imagetoraster filter now collects all printer options and job patch files and applies them to the page header as needed. - Added format and banner options to LPD backend. - The send-document operation didn't start a job immediately when last-document was true. - The set-job-attributes operation didn't correctly replace the current job-hold-until value. - Removed the option wrapper code from ppdEmit() and friends since it caused problems with Ghostscript and many PS printers. - Was setting TZ environment variable twice for job filters. - Added syslog logging in cups-lpd to aide in debugging problems. - The HP-UX parallel port backend did not list the available parallel ports on some systems (printf calling problem...) - The lp and lpr commands overrode user options if -d/-P were specified after -o. - The scheduler would crash with a */* filter. - Added support for a "default" filter for unknown file types. The example provided in the mime.types and mime.convs file prints unknown files as if "-oraw" was specified for the job. This functionality is disabled by default. - The "compatibility" mode fix for older backends did not work for smbspool. Added a workaround for it. - The HP-GL/2 filter didn't perform the right pen scaling with some files and the "fitplot" option. - New Software Performance Specification document that describes the memory, disk, and CPU usage of all the CUPS software. CHANGES IN CUPS v1.1.1 - The pstoraster Makefile still referenced one of the old PDF filter files. - The filter Makefile used INSTALL_DATA instead of INSTALL_LIB to install the CUPS image library. - The administration CGI didn't work properly with network devices. - The BrowseACL variable was not updated after the cupsd.conf file was loaded. - The lpd mini-daemon didn't support printer instances. - Now use a default umask of 077 for child processes. - Now put temp files in /var/spool/cups/tmp for child processes and the root user, unless TMPDIR or TempDir is defined otherwise. - cupsGetPPD() no longer uses easy-to-guess filenames. - The CUPS-Delete-Class and CUPS-Delete-Printer operations now save classes.conf file as needed. - The lppasswd command wouldn't add a user. - The ppdOpen() function could cause a segfault if a 0-length PPD file was read. - The image filters were not handling images with different X and Y resolutions properly. - The imagetoraster filter defaulted to RGB output instead of black output like pstoraster. - The pstops filter didn't handle binary data properly. - The pstops filter didn't handle copies properly for PS files lacking DSC comments. - The pstops filter now appends %%EOF to the end of documents if they don't have it. - The cupsGetPPD() function didn't work with remote printers lacking the @server in the name. - The configure script didn't work right when only --prefix was specified. - The ppdEmit() code now wraps all printer commands so that buggy PostScript printers will still print a file after receiving an option that isn't available. - Fixed the DeskJet margin bug, and disabled 600dpi color mode until it can be fixed. - The cupsAddDest() function didn't sort instances correctly in all cases. - The time-at-xyz attributes now expand to the date and time in banner files. CHANGES IN CUPS v1.1 - Documentation updates. - Configuration script updates. - Didn't map charset and language value strings to lowercase and _ to - as required by SLP and IPP. - ppdLoadXYZ() didn't add the list of available fonts to the ppd_file_t structure. - The text filter common code was freeing the PPD file data before it was used. - The text filter now embeds missing fonts. - The CGI interface now maps local access to the server to the localhost address. - The HP-GL/2 filter didn't use the specified (or default) color ranges, resulting in strange colors. - The HP-GL/2 filter didn't default to no input window, which caused unnecessary clipping of plots. - Integrated Xpdf's pdftops filter into CUPS, which is a lightweight and reliable replacement for Ghostscript's PDF support. - Removed all PDF support from Ghostscript. - Updated HP driver to set top margin; this seems to fix the offset problem seen on HP DeskJet printers. - Fixed dependencies on the ZLIB and JPEG libraries in pstoraster. - The lpr command wasn't using the lpoptions defined by the user. - The lpr command would segfault if the CUPS server was not running. - The top-level makefile was not installing the CUPS initialization script. It now does so if it sees there is an init.d directory in /sbin, /etc/rc.d, or /etc. - "lpstat -v all" didn't work. - pstoraster would crash on some platforms doing the setpagedevice operator. - The web administration interface now allows you to set the default banner pages. - Images can now be positioned on the page using the new "position" option. - The AccessLog, ErrorLog, and PageLog directives now support "%s" to insert the server name. - Added a new BrowseShortNames directive to allow for short remote printer names ("printer" instead of "printer@server") when possible. - The scheduler could crash if given an invalid PPD file with no PageSize attributes. - Updated the serial, parallel, and usb backends to do multiple writes and ignore ioctl() errors as needed; this should fix problems with serial printing on old serial drivers and with the UltraSPARC parallel port driver under Solaris 2.7. - Now propagate LD_LIBRARY_PATH to child processes from cupsd. - New DataDir directive for installing in alternate locations. - New CUPS_SERVERROOT and CUPS_DATADIR environment variables to specify installation directories as needed. - Queued remote jobs recreate remote printers as needed when the scheduler is started. - Deleting a printer also purges all jobs on that printer. - Old job and control files that don't belong to a printer are automatically deleted. - Wasn't updating time-at-processing and time-at-completed attributes in job. - Didn't send required multiple-operation-time-out attribute in response to a get-printer-attributes request. - cups-lpd now supports options set with lpoptions. - The job-hold-until attribute is now provided with all jobs.

CHANGES IN CUPS v1.1b4 - Documentation updates. - Many makefile and configuration script fixes (should now compile better under *BSD.) - The MediaPosition attribute was being mishandled by GhostScript, causing the RIP to fail whenever a paper tray was selected. - The scheduler now logs the final line of log information from a filter, even if it doesn't end with a newline; this primarily affects GhostScript error output. - The scheduler was saving implicit classes, so after a few restarts you'll end up with AnyPrinter, AnyAnyPrinter, etc. - The JPEG autodetection didn't work with some JPEG files that came from digital cameras (JPEG but not JFIF); the new magic types should work with all images that the JPEG library can handle. - Fixed a bug in the new contains() MIME type rule that could cause cupsd to crash. - Switched to using strtol() in the MIME type code so that you can use hex, octal, or decimal constants as desired in the mime.types file. - Banner files are now treated as templates, allowing any type of file to be used as a banner. - Added a 30-second timeout to backend device reports so that a hung backend will not prevent the scheduler from starting. - Backends are once again terminated when jobs are stopped; the CUPS-supplied backends will stay alive until the downstream filters have had a chance to clear out old page data. - The charset lookup in the CUPS localization support was wrong (iso8859-x instead of iso-8859-x) - Changed the "cpNNNN" code page files to "windows-NNNN" to match the IANA registrations. - New PostScript banner pages. - Added Windows BMP and Alias PIX image file support to the image filter. - The PNG reading coded didn't free all of its buffers. - Added Digest authentication support to the client and server code. - Added Solaris options to System V commands. - Now support the output-bin job template attribute. - Now log the job-billing attribute in the page_log file, and keep track of the total number of pages in the job-media-sheets-completed attribute. - The penwidth option is now in micrometers to support more accurate width specification. - The image filters now support interlaced and transparent PNG files. - Didn't handle Keep-Alive for HTTP/1.0 clients. - The BrowsePoll support didn't handle when BrowseInterval was set to 0 (now uses 30 seconds if BrowseInterval is 0) - The DeskJet driver now supports 600 DPI color for printers that support it. - New lpinfo and lpmove commands. - The lpq command now supports the Digital UNIX output format. - The LPD mini-daemon now supports all required LPD operations. - Implemented timeouts for multi-file documents. - New cupsPrintFiles() function in the CUPS API library to print multiple files using create-job and send-document requests (1 job ID for multiple files) - The lp command now sends multiple files as a single job, matching the behavior of the System V command. - The "cancel -a" command now purges job history files. CHANGES IN CUPS v1.1b3 - Documentation updates. - The startup script redirected stderr before stdout, which caused problems with some versions of Bourne shell and Bash. - Fixed a bug in the scheduler's PPD language reading code. - Fixed a bug in the scheduler's check for the manufacturer in the PPD. - The pstoraster filter didn't allow some input and output attributes to be set. - Added banner page support. - Added missing PAM configuration file. - Configuration script fixes for Linux and *BSD. - The log file code was using the wrong sign for the timezone offset. - The default printcap file is now empty (no printcap file is generated). - The scheduler did not start jobs destined for remote printers when they became available. - The scheduler now sends jobs to remote printers immediately. (when sending jobs to a class, the remote printer is only used when it becomes available) - The scheduler now supports printing of banner pages via the job-sheets attribute (banner files go in /usr/share/cups/banners) - The cupsd process now forks itself into the background (override with -f) - Added several *BSD enhancements. - Added UNSUPPORTED libtool option to configuration script to allow the use of libtool. Note that this is UNSUPPORTED by us, but added by request of the *BSD folks. - The parallel, serial, and usb backends now retry the opening of their ports. This allows multiple print queues to be associated with a single physical port, and will allow CUPS to support several types of parallel port auto-switches in the near future. - Set-Job-Attributes now supports adding, changing, and deleting job template attributes, and no longer allows job-printer-uri to be set (see CUPS-Move-Job) - Added CUPS-Move-Job operation to support moving of jobs. - The CGI template functionality now supports multiple languages (still only have templates for English) - The CUPS-Get-Printers and CUPS-Get-Classes operations now support filtering as defined in the IDD. - The Get-Jobs, CUPS-Get-Printers, and CUPS-Get-Classes operations no longer limit themselves to 1000 jobs, printers, or classes (believe it or not, this is needed for some sites) - The web interfaces now support language-specific templates. - The web admin interface now supports class management. - The web admin interface now shows a list of manufacturers before selecting the PPD/driver for a specific printer. - The web admin interface now supports configuration of the default printer options in the PPD file. - The web interface now uses printer/class authentication for the test page instead of admin authentication. - Updated the RPM spec file for the current release. - Updated language support for Windows code pages. - 8-bit character set files can now use multiple fonts (needed for Arabic, Greek, Hebrew, etc.) - Added basic right-to-left text support in the text filter. - The POSIX locale now uses ISO-8859-1 instead of US-ASCII. - Fixed PDF printing problems. - Fixed PostScript RIP page device dictionary elements that weren't getting passed in cups_get_params(). - Added a new "contains" rule for the magic file typing. - The "printable" rule now accepts characters from 128 to 255 (needed for Microsoft character sets) - Added support for ~/.cupsrc as well as /etc/cups/client.conf so that the default server can be configured on a per-user basis without environment variables. - Added LPD mini-daemon to support incoming LPD jobs. CHANGES IN CUPS v1.1b2 - Documentation updates. - The lp command didn't always load the user-defined destinations, preventing it from seeing the default printer. - Many configure script and makefile fixes. - The Microsoft code page files were missing from the distribution. - Added a workaround for the HP IPP client (which is sending an invalid printer-uri in requests) - Fixed the encoding of text-with-language and name-with-language to match the IPP spec. - Added support for unknown value tags in the IPP routines (previously they would be ignored) - Integrated GNU GhostScript 5.50 into the pstoraster filter. - Client hostname resolution was broken on little-endian machines. - Now look at client.conf file for client's default server and printer. - The cupsServer() function did not close the client.conf file if it contained a ServerName directive. - Added BrowseAllow, BrowseDeny, BrowseOrder, BrowsePoll, and BrowseRelay directives. - BrowseInterval 0 disables advertising of local printers, but still receives information on remote printers. - New browse polling daemon (for polling servers on different networks) - New PPD cache file for faster startup times with large numbers of PPD files. - The Host: field was incorrectly required for HTTP/1.0 clients. - New set-job-attributes operation now supported. - The mime_load_types() and mime_load_convs() functions did not close their input files.
