distcc-2.18.3 "Porsche safari" 2004-11-30 BUG FIXES: * Fix for incorrect handling of -x and -specs from Michal Welnicki. TESTS: * Fix false pass in tests for -x and -specs. distcc-2.18.2 "Bees and lavender" 2004-11-12 BUG FIXES: * Fix problem in checking errno after connect(). Fix by Jean Delvare and Dan Kegel. PORTABILITY: * Fix prototype problem causing build failure on amd64. Patch from Andreas Jochens. (Debian #280399, #280644). distcc-2.18.1 "Reality-based computing" 2004-11-03 BUG FIXES: * Fix run-time warnings about gtk_tree_model_row_changed() when built with recent versions of GTK+. * gcc option -specs= must be run locally so that it can read the local spec file. Reported by Chris Yeoh. PORTABILITY: * Fix Solaris build problem reported by Dimitri Papadopoulos. * Fix problem with reading hosts files in DOS CRLF format. Reported by Sebastien Perochon. distcc-2.18 "Billionaires on stilts" 2004-10-12 BUG FIXES: * Fix longjmp() bug that can cause distcc to crash when a timeout elapses. * Fix compile-time problem with dcc_trace when configured with --enable-rfc2553. Reported by Greg Earle. * Fix warning about warn_unused_result for older versions of gcc. * No timeout on local preprocessing or on compilation. No timeouts on DNS lookups other than whatever is built in to the DNS resolver. There are timeouts on network transmission and on opening connections. * Remove mmap() for receive of uncompressed data, to avoid various problems. CHANGES: * The --allow option is now mandatory for daemon mode. As a security feature, distccd will refuse to run without an IP access control list. * conftest.* built by autoconf is always done locally, to make configure tests faster and safer. DOCUMENTATION: * Better description of use with ccache. PORTABILITY: * Fix various warnings reported by Dimitri Papadopoulos. * Fix Tru64 build problem reported by Gary V. Vaughan. distcc-2.17 "Divers Alarums" 2004-07-31 FEATURES: * Performance improvements for distccmon-gnome. * Added timeous for connection to servers, transmission of jobs and remote compilation. If the timeout expires, the job is run locally. This should make distcc cope better if some or all of the servers are unreachable or failing. * Also add timeouts in server to kick out stalled or disconnected clients. BUG FIXES: * If remote compilation fails because of a signal in a later phase of the compilation causing an exit with code >=128, retry compilation locally. Patch from Jakub Stachowski. DOCUMENTATION: * Manpage fix from Jean Delvare. PORTABILITY: * Cygwin portability fix for WCOREDUMP, reported by Eric Frias. distcc-2.16 "Salt" 2004-07-08 SECURITY: * Fix bug that might cause IP-based access control rules not to be interpreted correctly on 64-bit platforms. (CAN-2004-0601) BUG FIXES: * Fix small memory leaks in distccmon-gnome and distccmon-text. FEATURES: * Use a GNOME status bar with a grab handle for distccmon-gnome. Patch from Nathan Fredrickson. PORTABILITY: * Better detection of systems with a popt library installed but no popt.h. Reported by Sean Kelly. * Fix bug in reporting crashed daemon children that showed up on systems without strsignal, such as Mac OS 10.2. Reported by Benjamin Reed. * Update testdistcc.py to work on ia64 linux. INTERNAL: * Simplify dcc_log_child_exited. * Include copyright and licence in --version output, as suggested by GNU programs. distcc-2.15 "feel good for ten seconds" 2004-07-06 BUG FIXES: * Fix crash bug in receiving LZO compressed data into a mmapped file. Reported by Arkadiusz Miskiewicz. * Remove redundant temporary file cleanup in non-forking mode. FEATURES: * Client calculates and can display the overall throughput in preprocessed bytes per second for remote jobs. REMOVALS: * The deprecated fork-after-exec mode controlled by the --no-prefork option has been removed. * mmap is no longer used for compressed data to simplify the code. PORTABILITY: * Additional fixes to Red Hat / Fedora scripts, by Colins Walters. INTERNAL: * Daemon now chdirs to $TMPDIR at startup rather than /. This allows dumping core, among other things. distcc-2.14 "Lake Albina" 2004-05-02 FEATURES: * The host file is looked up in $DISTCC_DIR/hosts, not hardcoded to ~/.distcc/hosts. The default for $DISTCC_DIR is still ~/.distcc. Suggested by Sebastien Perochon. * Source file name is included in success/failure messages, e.g. distcc[6655] ERROR: compile ./cases/bad.c on cardhu failed * distcc can now be built with a build directory separate from the source directory. Patch from Dennis Henriksen. DOCUMENTATION: * Add documentation of DISTCC_DIR, and other fixes. Patch from Thomas Schwinge. * Slightly improved distcc --help. BUG FIXES: * Decompression buffer can dynamically resize to allow for very gassy files. From a patch by Joe Buehler. PORTABILITY: * Add sample scripts for Red Hat / Fedora, by Colin Walters. * mmap is always disabled on HP-UX, because the inconsistent page case is a bit dangerous for the way distcc uses mmap. Suggested by Joe Buehler. distcc-2.13 "Carnal Bunt" 2004-03-02 SECURITY: * Enforce IPv4 access control lists when the daemon is listening on an IPv6 port. This only applies when the server was compiled using --enable-rfc2553 and run with --allow. FEATURES: * Hash comments are allowed in host list files. INTERNAL: * Use TCP_DEFER_ACCEPT on Linux to avoid some wasted context switching when a new connection comes in to the server. BUG FIXES: * Some fixes for connections over SSH when built using --enable-rfc2553. Reported by Jeff Rizzo. * Handle arguments like "-xcpp" and "-Wa,-xarch=v8". Suggested by Ben Scarlet. * Fix resource exhaustion when DISTCC_SAVE_TEMPS is set. Reported by Mark DeGeorge. * Fix problems in running IPv6-enabled builds on kernels without IPv6 support. Reported by Lisa Seelye. DOCUMENTATION: * More instructions for distributors/packagers. PORTABILITY: * Many portability patches from Albert Chin. These patches were tested on: AIX 4.3.2, 5.1; HP-UX 10.20, 11.00, 11i; IRIX 6.5; Redhat Linux 7.1, 9; Solaris 2.5.1, 2.6, 7, 8, 9; Tru64 UNIX 4.0D, 5.1. * Possibly fix mmap problem on HP-UX with compressed transfers. Reported by Joe Buehler. TESTING: * Add test for compilation with compression. * Testsuite portability patch from Albert Chin. The tests pass on: HP-UX 10.20, 11.00, 11i; IRIX 6.5; Redhat Linux7.1, 9; Solaris 7, 8, 9; Tru64 UNIX 4.0d, 5.1. distcc-2.12.1 "Shatner's Bassoon" 2004-01-09 BUG FIXES: * When checking if a process exists, accept EPERM as indicating it exists but isn't ours. This allows watching the directory of a different user, subject only to filesystem permissions. Reported by Ernst Bachmann. * Correct a bug introduced in 2.12 that made distccd fail to start when run by root because setgid failed. Fix from Wayne Davison. * --without-gnome, --without-gtk now turn those options off rather than on. DOCUMENTATION: * New man page for distccmon-text, by Shri Shrikumar and Martin Pool. distcc-2.12 "Figgy Pudding" 2003-12-19 FEATURES: * New --log-level feature allows logging of only errors rather than messages for each connection. * IPv6 support now works better when distcc is configured with --enable-rfc2553. The server can normally accept either IPv4 or IPv6 connections. * New --with-docdir configure option to set install location for documents. The default is the same as previously. Patch from Harold L Hunt II. INTERNAL: * GNU-style ChangeLog is now included in the package. Please keep it up to date if you make your own changes! PORTABILITY: * setgroups() was broken by Mac OS X Panther so that it will not accept setgroups(0, NULL) to clear the group list. Instead we now set the group list to our single primary gid. Suggestion from Wayne Davison. * sendfile problems on FreeBSD 4.9-RC fixed. Patch from Allan Saddi. * MAXPATHLEN is provided if it's not defined, which is the case on GNU Hurd. Reported by Santiago Vila as Debian #219600. BUG FIXES: * Check pkg-config information GNOME/GTK+ is now checked at configure time, not build time. This is a bit quicker than running the script for every file we build, and means that PKG_CONFIG_PATH only needs to be set for configure. DOCUMENTATION: * Small documentation corrections. distcc-2.11.2 "Muscovado" 2003-10-23 BUG FIXES: * Correct the handling of --without-gnome. Reported by Dimitri Papadopoulos. * Fatal signal handlers for client and daemon should reset the signal vector before doing anything else, to protect against an (unlikely) spin if the signal is re-sent. * Corrections to .desktop file from Dag Wieers. INTERNAL: * Remove dependency on libglade for GTK+ and GNOME monitor programs. PORTABILITY: * IRIX portability fixes from Dimitri Papadopoulos. * Use AC_TYPE_SIGNAL to generate correct signal handler return types. (It can be either int or void.) DOCUMENTATION: * Various manual updates. * Update to xinetd example from Dag Wieers. distcc-2.11.1 "Burnt sugar" 2003-10-08 FEATURES: * The graphical monitor can now be configured with either --with-gnome or --with-gtk. In the second case, the GNOME libraries are not used. In both cases the resulting program is called distccmon-gnome and the functional differences are fairly small. BUG FIXES: * An error message is emitted and compilation fails if distcc cannot use the specified TMPDIR. This can happen if distccd is started by root with a TMPDIR only accessible to root. Reported by Brett Dikeman. * GNOME data files are now only installed when the application is configured with --with-gnome or --with-gtk. Files are installed into a distcc/ subdirectory of the configured data directory. (By default this is /usr/local/share/distcc/). Reported by Erik Jan Tromp and Noe`l Ko"the. * Fix bug in sending compressed files where errors were ignored. * C++ compilation using -frepo must be local. Reported by Andrew Slater. PORTABILITY: * Don't use stdint.h, which is not available on FreeBSD 4-STABLE, IRIX or Solaris. Reported by Frerich Raabe. DOCUMENTATION: * Corrections to distcc manpage reported by Lionel Sausin. * Documentation of how to write monitor programs, from Frerich Raabe. INTERNAL: * Fix state.h for use with C++. Patch from Frerich Raabe. distcc-2.11 "Sugar fix" 2003-09-23 INCOMPATIBILITIES: * The GNOME monitor is now configured using --with-gnome (not --enable-gnome) to be more consistent with GNU standards. * The state file format has changed, so old distcc monitor programs will not see new compiler processes and vice versa. FEATURES: * Nice new GNOME monitor, showing strip-charts (or "scarves") of the state of each processor slot over time. * --allow 0.0.0.0/0 is accepted as meaning "allow access from anywhere". Debian #207831, suggested by Matthijs Kooijman. BUG FIXES: * If we fail to determine the number of CPUs on the machine, assume it is 1. This may fix problems on exotic machines where the detection call is almost but not quite right. * In non-forking mode, make sure to close the accepted fd after processing a request. * Use "safe" LZO1 decompression for protection against program or network errors. * Lock and state files are created with the weakest permissions permitted by the umask. This is intended to reduce problems seen when $DISTCC_DIR is shared between two users, such as when compiling as root during program installation. * Client deletes temporary files when interrupted. INTERNAL: * Add debugging option DISTCC_MMAP, which can be set to 0 to disable use of mmap for receiving files. * New --enable-profile configure option to turn on gprof. * Many changes to the representation of the client state to make it easier to draw a history. State is now stored as a natively encoded struct in a disk file, rather than using our network protocol. PERFORMANCE: * Sleep only one second when blocked waiting for a CPU, to try to reduce idle time when recovering from an overloaded period. DOCUMENTATION: * Document problems with "no_subtree_check" on NFS. * The GNU Free Documentation License is no longer distributed, because the documentation is now included under the GNU GPL. * Document bad Makefiles or mismatched compilers as common causes of failure. * Describe where to put "localhost" in the host list. PORTABILITY: * Fixes for BSD/OS (BSDi) from Nick Amato. * Fixes for portability issues in autogen.sh from Lisa Seelye and Alexandre Oliva. distcc-2.10.1 2003-08-12 BUG FIXES: * Fix problem in "make clean" reported by Lisa Seelye. distcc-2.10 "Hunger is the best sauce" 2003-08-11 SECURITY: * Fix issues in temporary file handling that could allow a local attacker to interfere with another user's distcc processes. FEATURES: * Daemon niceness is incremented by +5 by default. (This can be changed by --nice.) * The per-user configuration directory can be set by $DISTCC_DIR. It defaults to the old value of ~/.distcc/. * For regular compile failure, don't say "with exit code 1". BUG FIXES: * The server now emits warnings to the log and to the client if its PATH is set such that it will recursively run a distcc client. This check is done at run time for the requested compiler name. The server's $PATH is not modified in other ways. This may help reduce problems with finding the right remote compiler. PORTABILITY: * SCO/Caldera operating systems are no longer supported due to their recent absurd attacks against Linux and IBM. * TMPDIR is no longer required to start with '/', so that Cygwin paths starting with a drive letter may be used. Reported by Heiko Elger. DOCUMENTATION: * Various man page updates. INTERNAL: * Daemon now sits in the root directory while running, not the temporary directory. * Temporary directory is gone. Working files are created directly under $TMPDIR. * Lock files and state files are stored under DISTCC_DIR, rather than in /tmp. TESTING: * Test cases are more robust in choosing a daemon port number. distcc-2.9 "Grace under pressure" 2003-07-21 FEATURES: * Optional LZO1X compression of network traffic, to make distcc faster on slow or overloaded networks. This is turned on by appending ",lzo" to each host specification. Both client and server must be updated for this to work. Old clients and servers are supported when compression is off, which is the default. Compression is probably only worthwhile on networks slower than 100Mbps, but it will depend on the usual factors of CPU, network and code complexity. Thanks to Markus F.X.J. Oberhumer for the LZO library. BUG FIXES: * Handle invocations like "distcc foo.o -o foo", which can be generated by Mozilla. * Handle invocations like "distcc -Wa,-al=foo.lst -c foo.c", which write an assembler listing to a file and cannot be run remotely. * When trimming the path to avoid recursive invocations, stop as soon as we find one non-symlink compiler. This should help avoid the path getting trimmed down far too much on the server. Patch from Wayne Davison. PERFORMANCE: * The daemon by default allows 2+NCPUS, rather than 3*NCPUS. The two extras are to allow for some processes to be blocked on network IO, but allowing more than two of them is probably not useful on multiprocessor machines. * Larger files are sent and received using memory mappings where possible. * Use of mmap and compression makes distcc substantially faster in at least some cases. DOCUMENTATION: * Convert the documentation to a series of regular Unix manpages for easier reference and so they can be used more easily on diverse platforms. The Linuxdoc-SGML manual has been removed from the distribution. Thanks to Tim Potter for review suggestions. TESTING: * Add tests for new -o and -Wa,-al handling. distcc-2.8 "Play in the traffic" 2003-07-09 FEATURES: * Small enhancements to GNOME monitor appearance. BUG FIXES: * Fix problem with nonblocking IO for SSH connections that causes a busy spin. SSH connections are now far more efficient. Reported by Marcelo Matus. * distccmon-text flushes output after each line, even if stdout is not a terminal. This allows it to more easily be run in polling mode under another program. Suggestion from Hamish Rodda. * distccd now works properly with SSH servers that use pipes rather than socketpairs to run the daemon. Previously it would fail with an error when trying to write to stdin. Suggestion from Felix Lee. * Correctly handle invocations like "gcc -ofoo.o -c foo.c", where the output filename is run on to the -o option. Based on a patch from Tsutomu Yasuda. INTERNAL: * mon.h is now safe for inclusion in C++ programs, and protected against multiple inclusion. Suggestion from Frédérick Forjan. * Increased timeout for nonblocking network IO apart from connections to 5 minutes. PORTABILITY: * Detect and avoid Apple gcc cpp-precomp brokenness. Patch from Matt Watson. * Better handling of builds on machines which do not have the linuxdoc-sgml toolchain. Suggestion from Frerich Raabe. DOCUMENTATION: * Include an example xinetd configuration file from Andrew Morton. distcc-2.7.1 "Expedition" 2003-06-25 PORTABILITY: * distccmon-gnome now depends only on GTK+ 2.0, not on the GNOME libraries. * Fix for compilation of the GNOME monitor on BSD. * Fix for compilation of the monitor on Cygwin. distcc-2.7 "The Hard Way" 2003-06-16 FEATURES: * Graphical compile monitor for GNOME 2.x. Configure with --enable-gnome to build it. PORTABILITY: * Possible fix for compilation on HP-UX. INTERNAL: * Sanity check GNOME libraries during configuration if --enable-gnome was specified. distcc-2.6 "The Watcher in the Water" 2003-06-12 FEATURES: * New program distccmon-text shows the state of any distcc processes run by the current user. It can be run by hand or read by a shell script. Should be popular with vmstat fans. * New environment variable $UNCACHED_ERR_FD allows client errors to be redirected from stderr to another file descriptor, so that distcc errors are not cached by ccache. This is an improvment because (almost?) all distcc messages are transient things such as failure to connect to a remote host, and it is confusing to have them cached. (This needs a corresponding patch to ccache to set this, or for it to be assigned to a duplicate of stderr before invoking cccache.) * In compilation log message, just show the basename of the file to make it more compact. BUG FIXES: * If an compiler cannot be executed then try searching the path for the basename of the compiler. This can fix cases where the compiler is invoked with an absolute name but it is in a different directory on the server. Patch from Paul Russell. PORTABILITY: * Fix build on platforms that don't have hstrerror(), such as Solaris 2.6. * Handle sysconf(_SC_NPROCESSORS_ONLN) returning 0 processors, which has been observed on ARM Linux and previously threw distccd into a spin. Patch from Sean MacLennan. INTERNAL: * New mon.c interface for writing compilation monitors. * State directory name includes hostname for robustness when the temporary directory is shared. * Client writes out notes about its state to files that can be watched by external monitor programs. * Partial GNOME-based monitor interface, built when distcc is configured with --enable-gnome. TESTING * Fix silly typo that made maintainer-check give a false failure in ParseHostSpec_Case. distcc-2.5.1 "disable extra paranoia" 2003-06-05 FEATURES: * Fifteen second timeout on connection attempts. Hosts that are unreachable in this time are blacklisted for another minute. BUG FIXES: * Fix setpgid() failure when started directly from init(8). Reported by George Garvey. * Correct parsing of old-style TCP multiplier specification (e.g. "phathost/10:3600"). Patch from Wayne Davison. PORTABILITY: * Fix socklen_t compilation problem on Darwin. * Fix compilation problems on Solaris 8. Report from Tomas Ögren. * Fix compilation problems on IRIX. (IRIX cannot accept a variable named "sa_len".) Report from Peter Naulls. * Fix compilation on SuSE Linux 7.1 for Alpha. DOCUMENTATION: * Add more details about starting distccd to the user manual. TESTING: * Add test for correct parsing of old-style TCP multiplier specification (e.g. "phathost/10:3600"). distcc-2.5 "give them heaps" 2003-05-27 FEATURES: * The standalone daemon now "preforks" before accepting connections to reduce per-request overhead. Can be disabled by --no-prefork, which restores the standard Unix behaviour. * Restrict the number of jobs accepted onto the server at any time. By default this is determined automatically depending on the number of CPUs on the server, but it can be set using the --jobs, -j option. Replaces never-used --concurrent, -n option. * When the daemon is terminated, the entire process group is shut down, including any compilations in progress. * Load limits on TCP hosts can now be specified in the more consistent form of "HOST:PORT/MUL" rather than "HOST/MUL:PORT". The old form is still supported. * Better error message for "bind failed". * Better "listening on" message at startup. * More meaningful reporting of transmission and compilation times in logs. BUG FIXES: * Fix bug that caused some messages to go to the 'user' syslog facility rather than 'daemon' as presently. * Fix problem with terminating the daemon when running under Valgrind. INTERNAL: * Refactor daemon loop. * Server-side temporary object files are called .o, not .out. Suggestion from rishikesh shetty. * Temporary directory name changed to decimal userid, rather than hexadecimal userid. Easier to recognize. * Daemon changes into state directory at startup. * SSH child is collected and checked when the connection is closed. distcc-2.4.2 "hard and fast" 2003-05-23 BUG FIXES: * Fix compilation directed to /dev/null by handling output files the same way as the GNU BFD library. Reported by Hal Duston. * Better error messages if DISTCC_HOSTS or host files are empty. Patch from Wayne Davison. * Fix string allocation bug in dcc_sockaddr_to_ip that could cause a server crash. distcc-2.4.1 2003-05-22 PORTABILITY: * Add strndup() for non-GNU platforms. Patch from Frerich Raabe. distcc-2.4 "sparky will reign" 2003-05-21 FEATURES: * Preliminary support for distribution of Objective C and Objective C++ compilation. Based on a patch from Dara Hazeghi. * If remote compilation fails, give a visible error. People might want to know, particularly if something is failing on one particular machine. * Error messages report host definitions more consistently, rather than just hostnames. * Better handling of attempts to run more concurrent compilations than there are available slots. distcc now sleeps for a few seconds to avoid thrashing the client machine. * Unavailable servers are now shunned for 60 seconds so as to avoid wasting time connecting to machines that are down, not running distccd, etc. (However hosts that are simply not responding (e.g. firewalled) are not handled perfectly yet.) BUG FIXES: * If an IO error occurs while trying to get a lock, bail out rather than getting stuck. * Don't use the RFC2553 getaddrinfo/getnameinfo API by default, because it seems to be slower on OS X and possibly problematic on other systems. It can be enabled with --enable-rfc2553 if you want to use IPv6, multi-homed servers, or want to test the new API. PORTABILITY: * Preliminary STRATUS VOS portability work from Paul Green. DOCUMENTATION: * More description of execution over SSH. distcc-2.3 "come down like a ton of bricks" 2003-05-16 FEATURES: * Respond more gracefully to protocol derailments. In particular, banner messages sometimes seem to get into the stream when distcc is run from inetd, and they were previously a bit hard to diagnose. This won't fix the configuration problem that causes them, but it should make the problem obvious. * The client now tries all addresses for each server, in the order returned by the resolver. * Client and server now use IPv6 if requested, where this is supported by the system. The server still binds to an IPv4 address by default, but this can be set by the --listen option. Client access control is not supported yet for IPv6. BUG FIXES: * Fix possible bug in loading host list files. * Startup errors are now reported to stderr, unless that is a socket in which case they are sent to syslog. This should be a better tradeoff between making errors obvious and the requirements of inetd mode. DOCUMENTATION: * Add description of --listen to manual, plus other improvements. Patch from Frerich Raabe. * Various clarifications to the manual. * Add documentation of DISTCC_FALLBACK, DISTCC_SSH, execution over SSH, and host list files. PORTABILITY: * Two Mac OS X fixes from Benjamin Reed: Use the BSD method to discover the number of CPUs, and include types.h where it is needed. * Improved portability of snprintf fallback implementation. Now works again on dietlibc/Linux. Some fixes merged from Samba HEAD. distcc-2.2 "nosurname" 2003-05-05 FEATURES: * If $DISTCC_HOSTS is not set, the host list is taken from from ~/.distcc/hosts, if that exists, or otherwise ${sysconfdir}/distcc/hosts. (The location of this last one is set by the configure option --sysconfdir. It defaults to /usr/local/etc.) * Add --listen option to distccd, to control which IP address is used to listen for connections. May be useful for access control on dual-homed machines. Based on a patch by Neil Mansilla. DOCUMENTATION: * Add documentation for --allow and --user, by Frerich Raabe. TESTING: * Add test case for host list file. * Try to prevent server messages getting into syslog during testing. distcc-2.1 "Don't mind if I do!" 2003-05-03 FEATURES: * Support for execution over ssh! Hosts to be contacted over SSH should be specified as '@HOST' or 'USER@HOST'. distccd must be installed on the volunteer host, but it need not be running and there is no need to set up ssh tunnels. Compilations run under the user's account, and connections are securely authenticated and encrypted. SSH is substantially slower than plain TCP connections, but they can still be faster than local compilation. * The search path is examined in both the client and server, and directories containing distcc (and ccache, where appropriate) masquerade hooks are removed. This should help prevent distcc accidentally invoking itself recursively on either client or server. Patch from Wayne Davison. BUG FIXES: * Fix up warning about pid file being removed twice. * Better error handling when corks are not supported on a particular system or socket. * Fix incorrect display of CPU usage statistics in server log and client. * Change behaviour of distccd for log messages encountered during startup, before options are parsed. These are now written to stderr only if that is a tty, and otherwise to syslog. This is intended to prevent log messages from distccd getting mixed into the network protocol when it is run from inetd. * Correctly trap unexpected end of input when copying a file using read/write. * Test harnesses may need snprintf.o linked in as well. Reported by Joe Meslovich as broken on Solaris. TESTING: * Add test that --allow does in fact deny connections as it should. * Add tests for parsing of --allow options. * Add DISTCC_FALLBACK environment variable. If set to 0, means that failure to distribute will be considered an overall failure. By default, a networking error means that compilation will be retried locally. INTERNALS: * Many cleanups of error handling code. * Trace distcc version at startup to help with bug reporting. * Update IO code to handle nonblocking sockets, because we (may?) need to use nonblocking socketpairs to talk to SSH. distcc-2.0.1 "colorful savings on all your favorite medications" 2003-03-28 BUG FIXES: * Fix comfychair.py library missing from distribution. distcc-2.0 "shoot through like a Bondi tram" 2003-03-28 BUG FIXES: * Fix small signal handling race that would occasionally cause distccd not to exit when signalled. Pointed out by Vance Lankhaar. * If DISTCC_LOG is an empty string, treat as undefined. * If the file specified by DISTCC_LOG can't be opened, then show an error and use stderr. Previously, error messages were just lost. FEATURES: * New "masquerade" mode: distcc can be linked into a directory on the search path as 'cc'. By Wayne Davison and Martin Pool. * Detect number of online processors on the server. At the moment it is just logged but in the future it might be used to guide scheduling. Thanks to Dimitri Papadopoulos-Orfanos for describing how to do this on many operating systems. * Log signal name when terminating, on systems with strsignal(). PERFORMANCE: * Internal CPU efficiency fixes in logging and RPC code. PORTABILITY: * Apparently now builds on IRIX. Reports about whether it works would be welcome. * Fix cast in call to sprintf for platforms where ssize_t != int. Found on Alpha Linux in the hp Compaq testdrive. * Clean up some warnings on IRIX. * Fix problem with vsnprintf() declarations on Solaris 8. * Cope when in_addr_t and socklen_t are not defined, as is the case on FreeBSD 3.3. * Fix test suite to allow for 'true' and 'false' being in /usr/bin on BSD. TESTING: * Many internal updates to ComfyChair framework. * Test suite now works with Python 1.5 or later. * Add new undocumented (heh) "--lifetime" option that causes the daemon to expire after a certain period. * Specify limited lifetime when running daemon, so that if it is not cleaned up by the tests it will go away after a little while anyhow. * Use "--allow" to limit connections to localhost when running daemon for testing. * Use randomly chosen TCP port for the server when running tests. This makes repeated or concurrent invocations of the test less likely to conflict. * On machines without Python, just say "test skipped" rather than failing. * Test DISTCC_LOG being set to an unwriteable file. REMOVALS: * The GNU Info form of the manual is no longer included in the source distribution or installed by default. It can be built from SGML if desired, with "make install-linuxdoc-info". distcc-1.2.3 "stubborn tiny lights" 2003-03-02 PORTABILITY: * Don't use ':' in lock filenames, because that's a bit too tough for Windows. This only affects Cygwin clients, not servers. Pointed out by Heiko Elger. * Check existence of ctype.h. Fixes warnings when building popt. Pointed out by Tom Matelich. * Fix "access denied" errors on lock files on HP-UX and Cygwin, so clients on those platforms should work. Reported by Tom Matelich, Heiko Elger and others. distcc-1.2.2 "clustering darkness forever" 2003-02-27 BUG FIXES: * "make distclean" should not remove ./configure. PORTABILITY: * Don't assume POSIX-style reentrant file locks, which can't be supported on Cygwin. * Check for inet_aton in libresolv, which might fix Solaris 2.6. * Remove some gnudity from the Makefile in an attempt to build with non-GNU Make. * Attempted fix for header files on BSD. * Attempted sendfile implementation for HP-UX. TESTING: * Add a simple "make distcheck" target to test that the tarball is built properly. distcc-1.2.1 "you know you're right" 2003-02-25 BUG FIXES: * Better detection of python2.2 during configuration. * Allow installation from CVS on machines that don't have the Linuxdoc tools. * Check for autoconf >= 2.53 when configuring. Remove dependencies on features from later versions of autoconf to allow autogen to run on Red Hat Linux 7.2 systems. TESTING: * Add "make installcheck" target. * "make check" now fails if any of the tests fail to run. * distcc is now built on the build.samba.org build farm. Please contribute machines if you want your platform to be properly supported. PORTABILITY: * Remove libiberty, and use Samba's asprintf() implementation instead. Yay copy and paste. This should fix problems with asprintf and ansidecls.h on Solaris, BSD, and Cygwin. distcc-1.2 "lizard drinking" 2003-02-22 FEATURES: * New scheduler makes a better attempt at keeping remote machines solidly loaded by allowing only one request at a time to be in transit to remote machines, therefore letting the actual compiler start sooner. Gives about a 10% improvement in some circumstances. The new algorithm should also be a better foundation for adding compression or server-side load limiting. * New --allow option for distccd allows IP-based access control in either inetd or standalone daemon modes. * Locking mechanism now distinguishes between daemons on different ports of the same machine for the purposes of load balancing. * Print timing and estimated rate on bulk data transfers. * Open binary files in O_BINARY mode on Cygwin. May fix some corruption problems on this platform. More investigation would be appreciated. Based on a patch by Helind. PORTABILITY: * Use putenv() rather than setenv() to fit into SUSv2 and work on Solaris 8. Pointed out by Dimitri Papadopoulos. * Add some functions from libiberty to aid portability. distcc-1.1 "balls to the wall" 2003-01-28 BUGS: * Flag platforms that have a sendfile() function, but that aren't explicitly supported, because it seems to vary substantially. At the moment only FreeBSD and Linux are known. * Fix configure test for hstrerror(). Patch from Frerich Raabe. * Check for inadvertent recursion, where distcc calls itself as the compiler. Causes an exit with value 111. * Don't log client hostname, only the IP address. It's not really necessary and can slow us down. * If run by root, discard privileges rather than flagging an error. The persona to assume is set by the --user option and defaults to "distcc". The user "nobody" or uid 65534 is used as a fallback if the named user is not found. BENCHMARK: * Allow for running benchmarks repeatedly, printing the mean and standard deviation of run time. * Projects may now be selected by an unambiguous prefix of their name, so you can just say "benchmark hello" rather than "benchmark hello-2.1.1". * Print better explanatory messages while the benchmark is running. TESTING: * Update some tests to work with changed behaviour of gcc 3.2 as well as 2.95. DOCUMENTATION: * Many updates to distcc User Manual. * Comply with GNU Standards by keeping all messages in the NEWS file, not just those for the current release. distcc-1.0 "consider the oyster" 2003-01-16 BUG FIXES: * Fix sendfile() bug on FreeBSD that could cause files to be mistransmitted. Perhaps not manifest on x86? Reported by Kris Kennaway. PACKAGING: * Distribute as .tar.bz2 rather than .tar.gz. (We pay by the byte.) DOCUMENTATION: * The recommended convention for gcc names is -gcc-, and GCC 3.3 will install itself under this name. (Alexandre Oliva, Claes Wallin) BENCHMARK: * New macro-benchmark and test suite for distcc. Invoke it with "make benchmark." It takes a long time to run and causes a lot of source code to be downloaded, but should be self-contained. This is the start of a script that runs distcc to build various open source programs, as an overall test of correctness, and to measure performance of a distcc installation. It relies on the user to install and configure distcc servers and clients, but handles the work of downloading, preparing, and building packages by itself. There are still some rough edges on the script, but it may be of interest. * Add control over which phases of the benchmark are run. * Add ability to run tests repeatedly and report mean and standard deviation. REMOVALS: * Remove Plucker file: nobody seems to be downloading it, and it's easy enough for people to build if they're interested. * Remove PDF and Postscript from documentation in tarball. They are still available from the web site or may be built from source. distcc-0.15 "petrified forest" 2002-12-12 INCOMPATIBILITIES: * Change default port from 4200 to IANA-assigned standard for distcc service "3632". Compatibility with old installations can be retained by explicitly setting --port=4200 on the server, or using "HOST:PORT" on the client. * Fake-root directory for "make install" is now set by DESTDIR, not TARGET_ROOT. (Alexandre Oliva.) BUG FIXES: * Run the preprocessor with output sent to stdout and redirected to a file, rather than by using the -o option. This should fix some compilers that can't handle "-E -o". It may improve gcc behaviour with -MD, but because gcc behaviour has changed over time it may not be a complete fix. For gcc 3.2 it is recommended that -MF be used to explicitly set the dependency output filename. TESTING: * Add test case for transmission of a zero-byte file. * Add badly-behaved compiler drop-in for use in testing. PORTABILITY: * Use the correct autoconf macros to detect whether install(1) is available and working, and if not, fall back to using the included install-sh script. This should fix "make install" on Solaris. (Mike Santy) * Fix waitpid() takes three options. Required for Irix. (Michael Santy) * Fix autoconf detection of resolv.h on Solaris. (Dimitri Papadopoulos) DOCUMENTATION: * Describe information to include in a bug report. * Remove "Results" chapter from manual: there are now many more detailed results on the web site, and this information is better suited to storage there, because it will be updated on a different cycle. End-users don't really need to have it in their reference. * Remove "MOC Compatibility" section from manual because at the moment there is nothing to say. * Add a new section about the complexities of gcc -MD. * Remove "Bugs" section from the manual, and put it into a new TOOD file instead. Keep information about reporting bugs and using the test suite, but put it in a different section. distcc-0.14 "no agonizing hanging weights" 2002-11-13 BUG FIXES: * Take lock on localhost only when compiling locally, not for all compilations. This removes the accidental limit of only 4 overall jobs. (Martin Pool) * Fix Makefile bug that caused HTML documentation to be missing from the distribution tarball. (Frerich Raabe, Martin Pool) * Make PreprocessPlainText_Case run in appropriate subdirectory. (Martin Pool) PORTABILITY: * Test for wait4 and wait3, which are missing on IRIX. (Mike Santy, Martin Pool) DOCUMENTATION: * Include example init.d script. (Jason Thomas) distcc-0.13 "Armistice" 2002-11-11 FEATURES: * New --no-detach option to cause the server not to detach from its parent. It still forks normally when a connection is accepted. This may be useful with daemontools or other frameworks that prefer the daemon not to detach. (Martin Pool) * Log messages on the server of severity "warning" or higher are captured and sent back to the client. (Martin Pool) * If the local preprocessor fails, do not re-run the job locally because it would presumably fail in the same way. (Martin Pool) * By default, the client only sends "warning" or higher messages to stderr, so that nothing extra is logged unless there is possibly a failure in distcc itself. With a DISTCC_LOG file, "notices" and higher are logged. (Martin Pool) * Better messages when a compiler exits or crashes. (Martin Pool) * If the compiler because of a signal, return 128+SIGNAL, per Unix convention. (Martin Pool) * Compilers and preprocessors are now run in their own process groups, and terminated if the daemon is killed. (Martin Pool) * When the daemon parent is terminated, it does not kill all its children. Instead, they're allowed to finish whatever they're working on, and then exit. This allows for more graceful shutdown. (Martin Pool) * More specific exit codes for some error cases. Don't panic. (Martin Pool) * Include popt library and --with-included-popt configure option to aid installation on systems that don't have it. By default it is statically linked in only if the build machine does not have a suitable library and header. (Martin Pool) REMOVALS: * Remove support for feeding the compiler from a fifo. The gain from using fifos does not seem to justify the maintenance burden. (Martin Pool) - This makes the behaviour more consistent, because some platforms (Cygwin) or filesystems (NFS, strangely) can't use fifos. It removes a code path and a slightly complex autodetection. - Using fifos makes some potential scheduling improvements hard: the server can't make good decisions about how many tasks to run, because each one will only use a fraction of the CPU. The client cannot serialize file transmission, which would probably be desirable. - Using fifos makes reliably handling compiler failures slightly harder: the compiler may crash or exit at any time, which will in turn cause the server to hang if it later tries to open or write to the fifo. In previous versions, distcc tried to handle this by catching SIGCHLD when the child terminated, and aborting the operation, but I am not sure that the method is completely reliable. BUG FIXES: * Detached daemon now ignores hangup signal. (Martin Pool) * When the parent is terminated, don't kill its process group. Allow children to finish in their own time. (Martin Pool) * Detect the case where cpp claims to have succeeded, but did not actually produce any output. (Martin Pool) * Do not use atexit() to clean up temporary files, because this can cause havoc if it's ever called from a child process that forked but failed to exec. (Martin Pool) * Handle "gcc -S foo.c -o -", which ought to write assembly to stdout. (Alexandre Oliva) * Fix bug in handling IO errors (e.g. dropped connection) in the server. (Martin Pool) * If we fail to cork a socket, continue anyhow. (Martin Pool) * Make error handling for IO more consistent. (Martin Pool) * Follow Unix convention of returning 128+SIGNAL if the compiler exits with a signal. (Martin Pool) TESTING: * Add tests for parsing slot limit from host specification. (Martin Pool) * Daemon tests collect dead servers faster, so the tests run a bit faster. (Martin Pool) * Nicer handling of ^C while running tests: print "INTERRUPT" and terminate the whole test. (Martin Pool) * Add new tests for scanning command lines with an implied compiler name. (Martin Pool) * When the parent is terminated, don't kill its process group. Allow children to finish in their own time. (Martin Pool) * Detect the case where cpp claims to have succeeded, but did not actually produce any output. (Martin Pool) * Add test case for #error directive. (Martin Pool) * Add test case for preprocessing non-C text, as is done by (for example) xrdb. (Martin Pool) * Add test case for invocations like "distcc -c test1.c test2.c". (Martin Pool) * Add test for handling of a compiler missing from the server. (Martin Pool) * Allow distcc's version to be set to something like "0.13cvs-nofifo". (Martin Pool) * Add test for handling of a compiler missing from the server. (Martin Pool) * Improved ComfyChair testing framework. (Tim Potter, Martin Pool) PORTABILITY: * Includes example init.d script for SuSE 7.x and 8.0. Not installed by default. (Brandon Forehand) DOCUMENTATION: * Document use with Gentoo Linux. (Dean Bailey, Ernesto, Martin Pool) INTERNAL: * Get rid of recursive Make and fix various small Makefile bugs. (Martin Pool) * Add $(TARGET_ROOT) variable for "make install", for use in building binary packages. (Martin Pool, Nick Moffitt) * wait4() on Solaris can't handle a pid of -1, which means "any child" on Linux and BSD. Use pid of 0 instead to collect any children from the same process group. (Kevin Bailey) * Client does not abruptly drop network connection on compiler failure but rather reads the 0-byte object file token. (Martin Pool) * Rework logger library to allow multiple logger callbacks to be active at once. This is used for the server, which can write to its own log files and also send a copy of messages to a buffer to be sent to the client. (Martin Pool) distcc-0.12 "Klein, kosten- und schnörkellos" 2002-10-07 BUG FIXES: * Handle "gcc -S foo.c -o -", which ought to write assembly to stdout. (Alexandre Oliva) PORTABILITY: * wait4() on Solaris can't handle a pid of -1, which means "any child" on Linux and BSD. Use pid of 0 instead to collect any children from the same process group. (Kevin Bailey) TESTING: * Add tests for "-o -". (Martin Pool) distcc-0.11 "Nuclear Bedtime Story" 2002-09-25 FEATURES: * More helpful message explaining that popt is needed if it is missing at build time. (Martin Pool) * Better stripping of options from remote command lines. (Martin Pool) * Handle the new -MM, -MG, -MP, -MF, -MT, -MQ options for gcc 3.x. (Stephan Kulow, Martin Pool) PERFORMANCE: * Whenever a command by either the client or the server, it counts towards the load on that machine. This covers undistributed commands, cpp, and compilation. This should avoid the bias in earlier versions towards overloading the client. (Martin Pool) BUG FIXES: * IO errors should not cause the process to terminate straight away, because they are properly handled and we may have important cleanup to do. (Martin Pool) * Fix error handling in code for executing compilers. (Martin Pool) * Fix leakage of file descriptors when trying to acquire a lock. (Martin Pool) * Do not object to running as group 0, because on BSD this is "wheel" and many non-privileged users are in it. (Frerich Raabe, Martin Pool) * Fix (non-exploitable) buffer overrun bug. (Dave Zarzycki) PORTABILITY: * Fixes to build on Linux libc5. (Richard Zidlicky, Martin Pool) TESTING: * Keep $TMPDIR separate for each test case. (Martin Pool) * testdistcc.py now optionally takes arguments saying which tests to run. (Martin Pool) * Test permissions on output files are correct. (Martin Pool) * Add more test cases for implicit compiler name handling. Extend h_scanargs to exercise this. (Martin Pool) * More tests for argument stripping. (Martin Pool) distcc-0.10 "shiny fast red thing" 2002-09-12 FEATURES: * Allow distcc to be directly used with the same syntax as a compiler: "distcc -c hello.c". At the moment, always calls "cc". (Martin Pool) * If distribution fails, show the name of the server that we were trying to use. (Martin Pool) * Strip -D, -I, -L, -M* options before passing the command line across the network, for clarity (and perhaps a tiny performance improvement.) Also, this allows new clients which support -MD to be used with old servers that can't handle it. (Martin Pool) BUG FIXES: * Correctly handle "gcc -c -S hello.c", which should only assemble, not compile. (Alexandre Oliva) * If the volunteer compiler exits without reading all of its input, return the compiler's own exit code across the network, rather than EXIT_DISTCC_FAILED. (Martin Pool) * Attempt to fix a race where the compiler process could exit without opening its input before we started writing to the FIFO. In that case, the daemon would hang forever waiting for the compiler to arrive. In the new code, SIGCHLD causes a longjmp to break out of trying to feed the compiler. (Martin Pool) * If .o file is 0 bytes or not created on the server, do not create it on the client either. (Martin Pool) * Fix bug that caused compilation to fail if an old compiler output file existed. (Martin Pool) * Try to make sure to uncork client socket before closing if cpp fails, to work around Linux 2.2 bug that causes the socket to jam in FIN_WAIT1. See . (Martin Pool) * Invocations of gcc that use -MD or -MMD can be distributed, although -M cannot be. Both client and server must be updated to make this work. (Martin Pool) * It turns out that .s and .S files in fact cannot be assembled remotely, because they might use the gas '.include' pseudo op, which is resolved by the assembler and would end up reading something from the volunteer's disk. (Richard Zidlicky, Martin Pool) PORTABILITY: * Solaris portability fixes. (Dimitri PAPADOPOULOS-ORFANOS) TESTS: * Test handling of -c and -S. (Martin Pool) * Test handling of a file that causes a preprocessor error. (Martin Pool) * Test compiler that succeeds without reading input. (Martin Pool) * Test many simple compilations, in case there is an infrequent error. (Martin Pool) * Test many concurrent compilations. (Martin Pool) * Test using -D on the compiler command line. (Martin Pool) * Tests for .s and .S files. (Martin Pool) distcc-0.9 "samui desu ne?" 2002-09-03 FEATURES: * Add new environment variable for client and server, DISTCC_TCP_CORK. Defaults to on, intended mostly for performance comparison or debugging. (Martin Pool) PORTABILITY: * Properly support platforms with 32-bit pids, such as Cygwin. (Aaron Lehmann, Martin Pool) * On FreeBSD, the sa_family_t type is defined in (Dennis Taylor) BUG FIXES: * Fix bugs related to leftover fifos in the temporary directory causing occasional server hangs. (Martin Pool) * Stop the compiler from inheriting file descriptors connected to the network. This was causing the client to hang if the server abnormally terminated while the compiler was reading from a fifo. (Martin Pool) * Handle the case of sendfile() transmitting only part of the supplied data, similarly to a short write on a socket. This doesn't often happen, but can occur if a ptrace debugger attaches while sendfile is running. (Martin Pool) * When run with --daemon and not --no-fork, the parent does not detach until the pid file has been created. This removes a slight race window that sometimes confused the test scripts. (Martin Pool) * Message for completion of local cpp now gives the correct hostname. (Martin Pool) * Do not try to collect daemon children if --no-fork was specified. (Martin Pool) * Set SIGPIPE handler back to default before starting compiler tasks. (Martin Pool) * If a network error is detected while feeding input to the compiler, then it is terminated with a SIGHUP. (Martin Pool) * If transmission to the server fails, close the socket sooner rather than later so as not to make the server process wait around unnecessarily. (Martin Pool) * Better handling of the case where the compiler command exits without reading its input. (Martin Pool) * Make sure compilation children are always properly collected, even if transmission failed. (Martin Pool) PERFORMANCE: * Write token/parameters using a single write() call. May be very slightly more efficient in CPU and perhaps packets. (Martin Pool) TESTS: * Display test names while they're running so that long tests are easier to follow. (Martin Pool) * When cleaning up after running the dameon, make sure it's really dead before proceeding, so that tests don't trip over each other. (Martin Pool) * New test of compilation of a largish (~4MB) C file to a ~5MB object file. (Martin Pool) distcc-0.8 "cat and girl" 2002-08-15 FEATURES: * If for any reason a job can't be distributed, it is run locally rather than failing. This includes servers which are not running or unreachable, servers which crash, bad host specifications, etc. (Martin Pool) * --help for distcc explains more about host specifications. (Martin Pool) BUG FIXES: * Correctly handle compilation of C++ code under ccache, by properly recognizing the .ii extension. (Stephen White, Chris Halls) * Boolean environment variables (e.g. DISTCC_SAVE_TEMPS, DISTCC_VERBOSE) are now consistently required to be literally "1" to count as true. (Martin Pool) DOCUMENTATION: * Document that $DISTCC_HOSTS can now specify ports. (Martin Pool) * Document --no-fifo and --log-stderr. (Martin Pool) distcc-0.7 "Pipeline Authority" 2002-08-05 FEATURES: * Can now either use fifos for feeding the compiler or not. This can be controlled by --no-fifo to the server. By default, it tries a fifo and falls back to using regular temporarily files if that fails, as it will on Cygwin or an NFS-mounted /tmp. (Martin Pool) * --log-stderr option, intended mainly for debugging or testing. (Martin Pool) * DISTCC_HOSTS can now specify non-default port numbers using "host:port" syntax. (Martin Pool) DOCUMENTATION: * Built documentation (HTML, PS, PDF, Info) is now shipped in the distributed tarball, so that you can more easily install it on a machine lacking the Linuxdoc SGML tools. You still need them to modify and rebuild the documentation, of course. (Martin Pool) BUG FIXES: * Log pid even if running with --no-fork. Remove pid file on exit. (Martin Pool) PORTABILITY: * Try fcntl locks in addition to lockf and flock; apparently this helps portability to Cygwin. (Martin Pool, Marco Alanen) * Port to Cygwin. (Martin Pool, Marco Alanen) * Partial port to Solaris. (Dimitri PAPADOPOULOS-ORFANOS, Martin Pool) TESTABILITY: * Further internal improvements to test suite. (Martin Pool) * Test suite should now run whether or not there is a daemon listening on localhost, because it uses a non-standard port for testing. (Martin Pool) distcc-0.6 "reptilian agenda" (12 July 2002) FEATURES: * Daemon now refuses to run as root, because this is just too ridiculously insecure. (Martin Pool) * Output shows CPU time taken by distcc and programs that it runs. (Martin Pool) * distcc will now distribute jobs which use -s to compile but not assemble. Previously they were always run locally, but there's no strong reason why they must be. Unfortunately you need to upgrade both the client and server for this to work, because old servers will refuse to run gcc with -s. (Martin Pool) BUG FIXES: * -M option implies that cpp must be run locally, because it will want to write dependency information to a file. (Martin Pool) * Add --daemon and --inetd options, so that you can properly start a remote daemon with a single-line ssh command. (Martin Pool) * Fix bugs related to collecting child processes. (Probably not very user-visible.) (Martin Pool) * Fixed some Makefile-related bugs causing "make install" breakage and similar things. (Martin Pool) * If the system supports sendfile, but the particular filesystem we're on (e.g. tmpfs) doesn't, then fall back to using read/write. (Eivind Magnus Hvidevold, Martin Pool) * Change to argument analyzer to placate Valgrind. Possibly this was a memory corruption bug, but I can't see it. I think Valgrind was just too picky. (Martin Pool) PORTABILITY: * Build on FreeBSD, though you do need GNU make. (Lauri Watts, Martin Pool) DOCUMENTATION: * Better description of how to do cross-compilation. (Martin Pool) TESTING: * Improved Python test suite. (Martin Pool) INTERNAL CHANGES: * Get rid of automake; just use plain autoconf 2.53. (Martin Pool) * If $DISTCC_SAVE_TEMPS is set to "1", then files are not actually deleted -- good for debugging. (Martin Pool) distcc-0.5 "Unacceptable Behaviour" (27 June 2002) FEATURES: * Use more specific return codes when the remote compiler fails: EXIT_COMPILER_CRASHED for a signal, or the return code from the compiler if it exited non-0. FIXES: * Fix bug in h_hosts that caused us to write off the end of the real argv[], rather than a copy. Thanks to Julian Seward. (Martin Pool) PORTABILITY: * Cope on compilers without varargs macros. (Petter Reinholdtsen, Martin Pool) * Build on Solaris. (Petter Reinholdtsen, Martin Pool) * FreeBSD fixes. (Claes Wallin, Frerich Raabe, Michael Nottebrock, Martin Pool) DOCUMENTATION: * Manpages are correctly distributed and installed. (Petter Reinholdtsen) TESTING: * Test suite now runs a server on localhost and tests against it, and shuts it down on completion. (Martin Pool) * More test cases. (Martin Pool) distcc-0.4 "Wisdom Like Silence" (9 June 2002) ENHANCEMENTS: * Assembly and assembly-with-preprocessor files can now be assembled remotely. (Martin Pool) * Client now emits no messages unless there is a warning or error, or $DISTCC_VERBOSE is specified. This improves operation with ccache. (Martin Pool) * Client and server both respect $TMPDIR if set. (Martin Pool) * Standalone server puts itself in the background and detaches from controlling tty. (Martin Pool) * Server has --port option. Currently useless, since there's no corresponding option on the client. (Martin Pool) * Server has --pid-file option. (Martin Pool) * Server now allows multiple concurrent compile tasks, forking per connection. (Martin Pool) BUG FIXES: * gcc invocations with -fprofile-arcs or -ftest-coverage that would emit coverage information to a local file are always run locally. (Martin Pool) * Handle lines like "gcc -c -c hello.c". (Martin Pool) DOCUMENTATION: * Various enhancements to the user manual. (Martin Pool) INTERNAL: * Add a partial test suite based on PyUnit. Python 2 is now required to run the test suite, though not to just build or run distcc. (Martin Pool) distcc-0.3 "The Anticipation of a New Lover's Arrival" (28 May 2002) ENHANCEMENTS: * Support C++ compilation (including with ccache) by correctly detecting prefixes. (Ian Reinhart Geiser, Martin Pool) * Use a FIFO to feed preprocessed source from the daemon into the compiler, so that compilation can be overlapped with network transit. (Martin Pool) BUG FIXES: * Only fiddle with the compiler's stdin/out/err when running on the server, not on the client. This should make cpp from stdin work. (Reported by Ian Reinhart Geiser from KDE) (Martin Pool) * Prevent server crashing on aborted connectiong by using EPIPE rather than SIGPIPE in daemon as well as client. (Martin Pool, Ben Elliston.) PORTABILITY: * Builds on GNU/Linux, FreeBSD, and others if you're lucky. (Martin Pool, Frerich Raabe, Luke Gorrie) INTERNAL: * Convert to using GNU automake and autoconf, so that distcc can better handle portability, distribution and testing. (Martin Pool, Frerich Raabe, Ian Reinhart Geiser) * Start adding some "make check" tests. (Martin Pool) distcc-0.2 (17 May 2002) ENHANCEMENTS: * First public release * Correctly and usefully builds various large programs Local variables: mode: indented-text indented-tabs-mode: nil coding: utf-8 End:
