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
and OpenSSL license exceptions.
- 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 <pam/pam_appl.h> instead of
<security/pam_appl.h>.
- 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...
- The cups-config script reported the wrong version
number.
- The cups-config script was installed in $(bindir)
instead of $(BINDIR).
- The init script did not correctly check for a running
cupsd under IRIX 5.x.
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 <stdlib.h> 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 configure script to check for /etc/pam.d and
to only set PAMDIR if it exists.
- 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.
- The scheduler would not force the default job sheets
for printers to the current classification setting.
- Added a new ippFindNextAttribute() function to the
CUPS API.
- ppdEmitJCL() now strips any leading path info from
the title string. This is only an issue for non-CUPS
clients that don't do this already...
- Other pstops fixed from Helge Blischke for printing
non-conforming documents.
- The MaxJobs parameter was not reset when loading the
cupsd.conf file.
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, <Limit>, <LimitExcept>, 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 <sys/ioctl.h>, 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. For jobs that are not currently held the value
is "no-hold".
- The scheduler was not sending "unknown" values in IPP
responses.
- The lpoptions command now accumulates options from
previous runs rather than replacing all options for a
printer.
- The IPP backend now switches to IPP/1.0 if a 1.1
request fails.
- The lpadmin and admin.cgi programs now validate new
printer and class names.
- The access_log file now includes the number of IPP bytes
received in a POST request.
CHANGES IN CUPS v1.1b5
- Documentation updates.
- The pstoraster filter didn't compile without the JPEG library.
- The cupsd server didn't support the HTTP OPTIONS request
method.
- Dropped the "CLOSE" method supported by the cupsd server.
(not defined in HTTP specification)
- Makefile/configure script fixes.
- Missing the job-restart template.
- Added IPP test suite for testing.
- Missing IPP documentation from binary distributions.
- Fixed multiple-document handling code when last-document
not specified.
- Added more checks to IPP requests to prevent bad requests
from getting through.
- Not all of the Ghostscript error output was being sent to
stderr.
- The PostScript filter now added PJL commands to set the
job name and display string, if supported.
- The scheduler would crash if the browse socket could not
be bound. Now disables browsing if port 631 (reserved for
IPP) is being used by a misbehaving daemon.
- The USB backend now looks for the older Linux 2.2.x USB
printer device filenames as well as the newer ones.
- The IPP backend now uses the UTF-8 charset exclusively,
since apparently only CUPS handles more than US-ASCII and
UTF-8...
- Wasn't quoting ( in PostScript banners...
- Send-document requests with no document-format attribute
could cause cupsd to crash.
- Old jobs in the spool directory might cause cupsd to
crash.
- CUPS now supports all of the recommended job-hold-until
keywords as well as name values of the form "HH:MM" and
"HH:MM:SS".
- Added placeholder pointer for TLS encryption to the HTTP
connection structure.
- Fixed the "fast poll" bug reported by DISA - the
status pipe wasn't being closed for multi-file jobs.
- Revamped put_params code in pstoraster to fix bitmap
allocation bug with FrameMaker output.
- Ripped out filename, etc. code from pstoraster as it
is a potential security hole.
- Added support for RIP_CACHE environment variable in the
new pstoraster.
- Fixed USB device filenames for Linux; now support new
pre-2.4 devices (/dev/usb/lp#) and 2.2 devices
(/dev/usblp#)
- Fixed accept-jobs crash with classes.
- Didn't include dot-matrix EPSON drivers in previous
release.
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.
CHANGES IN CUPS v1.1b1
- NEW web-based administration interface.
- NEW EPSON printer drivers.
- NEW user-defined printers and options.
- NEW persistent jobs and job history
- NEW IPP/1.1 support
- NEW template-based web interfaces.
- NEW CUPS-get-devices and CUPS-get-ppds operations.
- NEW support for create-job and send-file operations.
- NEW certificate-based authentication for local
administration.
- NEW USB backend.
- The lpr command now produces human-readable error messages.
- The lpq command now produces BSD standard format output
instead of OSF/1 output. This should resolve the SAMBA
print queue problems that have been reported.
- The IPP backend did not always detect when the "raw" option
was being used.
- The "lpstat -p" command would stop after the first active
printer.
- The "lpstat -v" command would stop before the first remote
printer.
CHANGES IN CUPS v1.0.5
- The HP-GL/2 filter did not correctly set the pen color
for pens other than #1.
- The scheduler would only accept 26 simultaneous jobs
under some OS releases (mkstemp() limitation.) It now
handles up to 2^32 simultaneous jobs.
- The PostScript filter loaded the printer's PPD file
twice.
- The PAM authentication code now uses pam_strerror() to
provide a textual error message in the error_log file.
- The scheduler now copies PPD and interface script
files instead of moving them; this fixes installations
with a separate requests directory.
- The PostScript RIP did not generate correct 6-color
output.
- Several filters were marking PPD options twice when
they didn't need to.
- The scheduler did not save the printer or class state
after an accept-jobs or reject-jobs operation.
- The cupsGetDefault() function now ignores the PRINTER
environment variable if it is set to "lp".
- New ippErrorString() function to get textual error
messages.
- Better error reporting in the System V commands.
- The lpadmin and lpstat commands always tried to
connect to the default server.
- The text filter didn't load the charset files from the
correct location.
- Wasn't sending a WWW-Authenticate: field to HTTP
clients when authentication was required.
- httpSeparate() didn't always set the default port
number for known methods.
- The HP-GL/2 filter now looks for "PSwidth,length"
instead of (the correct) "PSlength,width" as
documented by HP. It appears that many major CAD
applications are broken and this change allows the
auto-rotation to work with them.
- The IPP "printer-resolution" option was not being
translated.
- The charset files did not include the Microsoft
"standard" characters from 128 to 159 (unused by the
ISO-8859-x charsets)
- The scheduler was chunking the Content-Type field from
CGI programs; this problem was most noticeable with
Microsoft Internet Explorer 5.
- By popular demand, the printers, jobs, and classes
CGIs no longer force a reload of the page every 10/30
seconds.
- The scheduler incorrectly required that the IPP client
provide a document-format attribute for the
validate-job operation.
- Clients that sent bad IPP requests without the
required attributes-natural-language and
attributes-charset attributes would crash the
scheduler.
CHANGES IN CUPS v1.0.4
- Documentation updates.
- Jobs would get stuck in the queue and wouldn't print
until you enabled the queue.
- The lp and lpr commands now catch SIGHUP and SIGINTR.
- The lp and lpr commands now use sigaction or sigset
when available.
- CUPS library updates for WIN32/OS-2
CHANGES IN CUPS v1.0.3
- Documentation updates.
- The lpq man page was missing.
- The configure script was not properly detecting the
image libraries.
- The top-level makefile was calling "make" instead of
"$(MAKE)".
- PostScript filter fixes for number-up, OutputOrder,
and %Trailer.
- The imagetops filter didn't end the base-85 encoding
properly if the image data was not a multiple of 4
bytes in length.
- The imagetoraster filter didn't generate good banded
RGB or CMY data (was dividing the line width by 4
instead of 3...)
- The imagetoraster filter now records the bounding
box of the image on the page.
- The CUPS image library cache code wasn't working as
designed; images larger than the maximum RIP cache
would eventually thrash using the same cache tile.
- The CUPS image library TIFF loading code didn't
handle unknown resolution units properly; the fixed
code uses a default resolution of 128 PPI.
- cupsGetClasses() and cupsGetPrinters() did not free
existing strings if they ran out of memory.
- The scheduler logs incorrectly contained 3 digits for
the timezone offset instead of 4.
- The scheduler now does a lookup for the default user
and group ID; the previous hardcoded values caused
problems with the LPD backend.
- The cancel-job operation now allows any user in the
system group to cancel any job.
- The cancel-job operation stopped the print queue if
the job was being printed.
- Now only stop printers if the backend fails. If the
filter fails then the failure is noted in the
error_log and printing continues with the next file in
the queue.
- Now log whether a filter fails because of a signal
or because it returned a non-zero exit status.
- The root user now always passes the system group test.
- Printers with an interface script and remote printers
and classes didn't have a printer-make-and-model
attribute.
- Added logging of lost/timed-out remote printers.
- The HP-GL/2 filter was scaling the pen width twice.
- Updated the HP-GL/2 filter to use a single SP (Set
Pen) procedure. This makes the output smaller and is
more appropriate since the filter keeps track of the
pen states already.
- The scheduler didn't handle passwords with spaces.
- The IPP backend now does multiple copies and retries
if the destination server requires it (e.g. HP
JetDirect.)
- The disable command didn't implement the "-c" option
(cancel all jobs.)
- Changed the CMYK generation function for the image file
and PostScript RIPs.
- The lp command didn't support the "-h" option as
documented.
- The AppSocket, IPP, and LPD backends now retry on all
network errors. This should prevent stopped queues
caused by a printer being disconnected from the
network or powered off.
- The scheduler now restarts a job if the corresponding
printer is modified.
- The image RIPs now rotate the image if needed to fit
on the page.
CHANGES IN CUPS v1.0.2
- The HP-GL/2 filter didn't always scale the output
correctly.
- The HP-GL/2 filter now supports changing the page size
automatically when the "fitplot" option is not used.
- The cancel-job operation was expecting a resource name
of the form "/job/#" instead of "/jobs/#"; this
prevented the cancel and lprm commands from working.
- The backends didn't log pages when files were printed
using the "-oraw" option.
- The authorization code did not work with the Slackware
long shadow password package because its crypt() can
return NULL.
- The chunking code didn't work for reading the response
of a POST request.
- cupsGetPPD() now does authentication as needed.
- The N-up code in the PostScript filter didn't work
with some printers (grestoreall would restore the
default blank page and device settings).
- The N-up code in the PostScript filter didn't scale
the pages to fit within the imageable area of the
page.
- Wasn't doing an fchown() on the request files. This
caused problems when the default root account group
and CUPS group were not the same.
CHANGES IN CUPS v1.0.1
- Documentation updates.
- Fixed a bunch of possible buffer-overflow conditions.
- The scheduler now supports authentication using PAM.
- Updated the Italian message file.
- httpEncode64() didn't add an extra "=" if there was
only one byte in the last three-byte group.
- Now drop any trailing character set from the locale
string (e.g. "en_US.ISO_8859-1" becomes "en_US")
- Fixed "timezone" vs "tm_gmtoff" usage for BSD-based
operating systems.
- Updated IPP security so that "get" operations can be
done from any resource name; this allows the CGIs to
work with printer authentication enabled so long as
authentication isn't turned on for the whole "site".
- The IPP code didn't properly handle the "unsupported"
group; this caused problems with the HP JetDirect since
it doesn't seem to support the "copies" attribute.
- The HTTP chunking code was missing a CR LF pair at the
