| Summary: A Fast C/C++ Compiler Cache | |
ccache is a compiler cache. It speeds up recompilation by caching the result of previous compilations and detecting when the same compilation is being done again. Supported languages are C, C++, Objective-C and Objective-C++.
GPL-3.0-or-later
* Thu Jan 18 2024 danilo.spinella@suse.com
- Update to 4.9:
* Made ignore_options/CCACHE_IGNOREOPTIONS also skip the option from special
processing, similar to how --ccache-skip works.
* Added support for expanding environment variables references in all
configuration options.
* MSVC options /Fd, /FS and /MP are no longer included in the input hash.
* Made ccache terminate an ongoing compiler subprocess when terminated on all
platforms, not only on Unix.
* Added support for multiple -Xarch_* arguments matching -arch.
* Added a debug_level/CCACHE_DEBUGLEVEL configuration option, making it
possible to tell ccache to only write a log file for each compilation, not
other debug files.
* Added max_cache_size_kibibyte and max_files_in_cache fields in output from
ccache --print-stats.
* Paths after -Xclang -include are now rewritten to relative paths if
base_dir/CCACHE_BASEDIR is in effect.
* Added support for clang --analyze.
* Improved processing of input file arguments.
* Added support for st_Xtimensec fields in struct stat, thus improving
behavior on some BSDs when using newly created include files.
* Added support for the undocumented GCC/Clang option --include.
* Ccache now exits more gracefully on invalid sharded remote storage URLs.
* Made ccache bail out on too hard options -fmodules-ts, -fmodule-header,
- wrapper and -Xclang -ast-dump.
* Stopped relying on the st_blocks field in struct stat since it cannot be
trusted for filesystems such as ZFS that do transparent compression or
deduplication and adjust st_blocks some time in the future.
* Fixed crash on Windows for paths with only a drive letter.
* Made handling of Clang config options (such as --config-system-dir) more
robust.
* Fixed compiler type detection when compiler is a symlink called “clang-cl”.
* Made sure to use MSVC logic for clang-cl when handling a precompiled
header.
* Generalized expansion of remote storage URLs with sharding, for instance
making it possible to shard on port number.
* Upgraded to xxHash 0.8.2, thereby fixing an error when compiling ccache
with -Og.
* Fixed sign-compare warning in src/InodeCache.cpp on FreeBSD.
* Fixed the CMake option STATIC_LINK on Linux/macOS.
* Added the CMake option OFFLINE, defaulting to the value of the standard
variable FETCHCONTENT_FULLY_DISCONNECTED (which is OFF by default), to
disable downloading anything from the internet.
* Fixed warnings about unused functions on new MSVC versions.
* Made sure to set both C and C++ CMake compiler launcher variables if either
is set.
* The manual now mentions that system_headers sloppiness is not supported for
MSVC.
* Fixed regex in direct.bash.
- Fix SLE build by using gcc11 and disable hiredis dependency
* Sat Oct 28 2023 andreas.stieger@gmx.de
- update to 4.8.3
* Fixed handling of NVCC -Xcompiler and --Werror options
* Fixed bookkeeping of files when hard linking or file cloning is
enabled
* Made a workaround for GCC 12.3 bug 109241 where GCC fails to
compile ccache.
* Upgraded to xxHash 0.8.2, which fixes compilation of ccache
with GCC 12 and -Og.
- enable redis backend
* Mon Jun 12 2023 dmueller@suse.com
- update to 4.8.2:
* Ccache no longer passes `-v` to the preprocessor. This
improves preprocessor mode hit rate when `-v` is on the
compiler command line.
* Made `--trim-max-size` accept 0 for no limit. +
* Clarified `--evict-older-than` semantics.
* Fixed typo in "`Directory is not hashed if using -gz`" test.
* Fri May 19 2023 dmueller@suse.com
- update to 4.8.1:
* Fixed an issue with the depend mode in combination with `--`
on the command line for Clang-based compilers. +
* Improved knowledge about MSVC debug flags so that non-debug
`/Z*` options are once again supported. +
* Ccache no longer treats `/Zi` as unsupported for clang-cl.
* Made the output format of `ccache -k max_size` parsable by
ccache itself. +
* Added a remote file storage example with URL-encoded spaces.
* Mon Mar 13 2023 dmueller@suse.com
- update to 4.8:
* Improved the automatic cache cleanup mechanism. Automatic
cleanups are now performed on 1/256 of the cache instead of
1/16, thus making them much quicker (but naturally more frequent).
Cleanups are coordinated between ccache processes so that at most
one process will perform cleanup at a time. Also, the actual cache
size will stay very close to the configured maximum size instead of
staying around 90% as was the case before.
* Added support for setting per-compilation configuration options on
the command line. Example: `ccache hash_dir=false gcc -c example.c`
* Made it possible to disable ccache for a certain source code file
by embedding the string `ccache:disable` in a comment near the top
of the file.
* Made ccache understand that an MSVC `/Z7` option overrides an
earlier `/Z*` option and thus is not too hard to cache.
* Added a `--recompress-threads` command line option for selecting
the number of CPU threads to use when recompressing the local cache.
* Added `--trim-recompress` and `--trim-recompress-threads` command
line options for recompressing file-based remote storage.
* Added tmpfs, ufs and zfs to the list of supported filesystems on
macOS and BSDs for the inode cache.
* Improved progress bars for clean/clear/evict-style operations.
* Improved printing of cache sizes in various outputs.
* Activate debug logging for command mode options like `--cleanup`.
* Added support for `-Wp,-U<macro>` in the direct mode.
* Added quotes around arguments with space in logged command lines.
* Added logging of executed command lines on Windows. +
* Made sure not to update the stats file when there are no incremented
counters.
* Improved actual disk size calculation on Windows.
* Bugfixes
* Mon Dec 05 2022 dmueller@suse.com
- update to 4.7.4:
* Fixed an inode cache race condition.
* The default temporary directory is now `$XDG_RUNTIME_DIR/ccache-tmp`
instead of a hardcoded `/run/user/<UID>/ccache-tmp`. If `XDG_RUNTIME_DIR`
is not set, `<cache_dir>/tmp` is used. This avoids creating `/run/user/<UID>`
on systems that don't have it if compiling as root.
* Added a fallback in case `posix_fallocate` returns `EINVAL` when
creating the
inode cache file.
* Connection timeout for an HTTP connection is now reported as a timeout
instead
* Temporary files found in the cache are no longer counted in
`--show-compression`.
* Removed duplicate magic header in output from `--inspect`.
* Ccache now properly waits for all recompression jobs to finish when
there is no `f` subdirectory in the cache.
* Documentation improvements
* Thu Nov 17 2022 danilo.spinella@suse.com

* Sun Sep 18 2022 dmueller@suse.com
- update to 4.6.3:
* Fixed detection of PCH header for concatenated `-include` option (e.g.,
`-includepch.h` instead of `-include pch.h`).
* Fixed build with musl when using GCC 12.
* Disabled the `"Failure to write output file"` when running on a filesystem
that doesn't support read-only directories.
* Fixed a race condition that could lead to a crash if a file in the cache is
removed with unlucky timing, e.g. by another ccache process doing cache
cleanup.
* Dependency file rewriting will now always be performed if
`base_dir`/`CCACHE_BASEDIR` is active. This fixes a problem with the
dependency file content when Clang is used with `-fsanitize=address`.
* Fixed handling of error condition for `--hash-file`/`--checksum-file`.
* Made sure to enable the inode cache only if subsecond `stat` timestamps are
available.
* Added a work-around for a Clang bug when writing to a full NFS file system.
* Made failure writing to the output file increment the "`bad output file`"
counter instead of "`cache miss`".
* Fixed false positive cache hits for code constructions similar to
`__asm__(".incbin" " \"file\"")`.
* Fixed false success for `-fcolor-diagnostics` probe with GCC. A side effect of
this is that a compiler type that ccache can't identify from the compiler name
(such as `/usr/bin/cc` where `cc` is not a symlink) from now on won't produce
color diagnostics when used via ccache even if the compiler actually is GCC or
Clang.
* More cases of invalid secondary storage URLs are now handled gracefully.
* Fixed the display of maximum cache size in `ccache -s` if it's 0 (=
unlimited).
* Removed AsciiDoc markup from help text of `--trim-dir`.
* The temporary directory is now cleaned up properly even if it's left
unconfigured.
* Made cleanup of the temporary directory not rely a directory timestamp.
* Made sure to retain mtime/atime when recompressing cache files with
`-X`/`--recompress`.
* The correct umask is now used when populating the primary cache from a
secondary cache.
* Fixed creation of temporary files on file systems that don't support hard
links (such as FAT32).
* Added knowledge about `-Wa,...=file` so that ccache then falls back to running
the real compiler.
* Corrected handling of space in paths when using response file on Windows.
* Fixed crash due to empty include filename in preprocessor output generated by
`f2c`.
* Tue Aug 30 2022 bwiedemann@suse.com
- Add fix2038.patch to make tests pass after 2038
* Sat Jun 04 2022 dmueller@suse.com
- update to 4.6.1:
* Added support for passing a directory to the MSVC `/Fo` option.
* Added knowledge about the `-imsvc` compiler option.
* Added knowledge about the `-z` linker option.
* Improved handling of `.gcno` files in combination with absolute input file
paths.
* Adapted to changes in GCC 9+ `.gcno` files, which contain the current working
directory, by including said directory in the hash. You can opt out of this by
enabling "`gcno_cwd sloppiness`".
* A preexisting object file is no longer considered when using
`-fsyntax-only`.
* Authenticate with Redis before database selection.
* Don't exit with an error on failure reading a cached file.
* Bail out on too hard MSVC environment variables `CL` and `+_CL_+`.
* Only use `/run/user/<UID>/ccache-tmp` as the temporary directory if it's
writable.
* Fixed handling of the final newline in cached standard output from the
compiler.
* Fixed a bug related to distcc markers in standard error output.
* Paths to `base_dir` are now properly normalized on Windows.
* Fixed handling of MSVC `/Fp` and `/Yu` options with concatenated path.
* Fixed "`Multiple precompiled headers used`" error if MSVC `/Yu` option is used
after `/Fp`.
* Check for short reads when reading strings in result/manifest files.
* Log expanded secondary storage URL in put/remove.
* Fixed logging of statistics counters with value higher than one in debug log
and stats log.
* Avoid incorrect error log message for Redis write operations in `reshare`
mode.
* Support Redis URL without host (meaning localhost).
* Sun Apr 03 2022 andreas.stieger@gmx.de
- ccache 4.6:
* Add an option to use a bearer token with the HTTP backend.
* Add support for caching standard output from the compiler.
* Add a new --inspect option for debugging cache entries,
replacing the previous --dump-manifest and --dump-result
options
* Enable HTTP keep-alive by default
* Improve detection of the .incbin assembler directive to reduce
false positives
* Ccache now verifies that /run/user/<UID>/ccache-tmp is writable
before using it for temporary files
* Fix statistics output for secondary storage
* Fix a problem when copying a cache entry from secondary storage
into an empty primary storage.
* The process umask is now respected when making hard linked files
read only
* A forced recache is no longer considered a “direct cache miss”
* Documentation updates
- drop xxhash-avoid-armv6-unaligned-access.patch, included
* Fri Dec 17 2021 dmueller@suse.com
- add xxhash-avoid-armv6-unaligned-access.patch (bsc#1193317)
* Thu Dec 02 2021 dmueller@suse.com
- update to 4.5.1:
* Fixed entry_size field for result entries.
* The actual compression level is now once again stored in the cache entry
header.
* Corrected error handling for unconstructible secondary storage backends. For
instance, this avoids a crash when a Redis server can't be reached.
* Made various improvements to the cache entry format. Among other things, the
header now contains a creation timestamp and a note of the ccache version used
to create the entry. The cache entry checksum has also been upgraded to use
128-bit XXH3 instead 64-bit XXH3.
* Made HTTP keep-alive configurable, defaulting to off for now.
* Added support for rewriting absolute path to Clang option `--gcc-toolchain`.
* Fixed a problem with special characters in the user info part of URLs for HTTP
storage.
* The hard link and file clone features are now disabled when secondary storage
is used since they only work for the local primary cache.
* Thu Dec 02 2021 guillaume.gardet@opensuse.org
- Do not hide test failures in %check
* Thu Oct 14 2021 mpluskal@suse.com
- Update to version 4.4.2:
* See https://ccache.dev/releasenotes.html#_ccache_4_4_2 for detailed
list of changes
* Tue Sep 21 2021 mpluskal@suse.com
- Update to version 4.4.1:
* See https://ccache.dev/releasenotes.html#_ccache_4_4_1 for detailed
list of changes
* Wed Aug 25 2021 mpluskal@suse.com
- Update to version 4.4:
* See https://ccache.dev/releasenotes.html#_ccache_4_4 for detailed list
of changes
* Wed May 12 2021 andreas.stieger@gmx.de
- ccache 4.3:
* ignore Clang compiler option -ivfsoverlay
* When using -P in combination with -E, ccache now reports this
as "called for preprocessing" instead of "unsupported compiler
option"
* Add support for -specs file.specs and --specs file.specs
without an equal sign between the arguments
* multiple bug fixes
* Tue Apr 06 2021 mpluskal@suse.com
- Update to version 4.2.1:
* Ccache now only dup2`s stderr into `$UNCACHED_ERR_FD for calls to the preprocessor/compiler. This works around a complex bug in interaction with GNU Make, LTO linking and the Linux PTY driver.
* Fixed detection of color diagnostics usage when using -Xclang -fcolordiagnostics options.
* The -frecord-gcc-switches compiler option is now handled correctly to avoid false positive cache hits.
* Made it possible for per-compilation debug log files to be written in most argument processing error scenarios. Previously, ccache would only write debug log files if the argument processing phase was successful.
* Made ccache bail out on too hard Clang option -gen-cdb-fragment-path.
* The run_second_cpp made is now enforced on macOS if -g is used since newer Clang versions on macOS produce different debug information when compiling preprocessed code.
* Made ccache only reject -f(no-)color-diagnostics for a known GCC compiler. This fixes a problem when using said option with clang++ on macOS.
* Build configuration scripts now probe for atomic increment as well. This fixes a linking error on Sparc.
* An existing CMake log message level is now used when warning about not finding asciidoc.
* Fixed assertion in the "Debug option" test.
* Upgraded to doctest 2.4.6. This fixes a build error with glibc >= 2.34.
* Thu Feb 04 2021 mpluskal@suse.com
- Update to version 4.2:
* Improved calculation of relative paths when using base_dir to also consider canonical paths (i.e. paths with dereferenced symlinks) as candidates.
* Added a debug_dir (CCACHE_DEBUGDIR) configuration setting for specifying a directory for files written in debug mode.
* Added support for compiler option -x cuda, understood by Clang.
* The value of the SOURCE_DATE_EPOCH variable is now only hashed if it potentially affects the output from ccache. This means that ccache now (like before version 4.0) will be able produce cache hits for source code that doesn’t contain __DATE__ or __TIME__ macros regardless of the value of SOURCE_DATE_EPOCH.
* Mon Nov 23 2020 paul.fee@jci.com
- Update to version 4.1:
* Symlinks are now followed when guessing the compiler, e.g. /usr/bin/c++ -> g++10
* Added a new compiler_type (CCACHE_COMPILERTYPE) configuration option that allows for overriding the guessed compiler type.
* Added support for caching compilations with -fsyntax-only.
* Added a command line option --config-path, which specifies the configuration file to operate on. It can be used instead of setting CCACHE_CONFIGPATH temporarily.
* Wed Nov 04 2020 mpluskal@suse.com
- Update to version 4.0:
* Changed the default cache directory location to follow the XDG base directory specification.
* Changed compression algorithm from Deflate (zlib) to Zstandard, enabled by default.
* Added functionality for recompressing cache content with a higher compression level.
* Changed hash algorithm from MD4 to BLAKE3.
* Added checksumming with XXH3 to detect data corruption.
* Improved cache directory structure.
* Added support for using file cloning (AKA “reflinks”).
* Added an experimental “inode cache” for file hashes.
- Changes for version 3.7.12:
* Coverage files (.gcno) produced by GCC 9+ when using -fprofile-dir=dir are now handled gracefully by falling back to running the compiler.
* Fixed writing to log file larger than 2 GiB when running ccache compiled in 32-bit mode.
- Drop no longer applying patch:
* 0001-Add-another-cleanup-mechanism-evict-older-than.patch
* Sun Jul 26 2020 elimat@opensuse.org
- Update to version 3.7.11:
* Added knowledge about -fprofile-{correction,reorder-functions,values}.
* ccache now handles the Intel compiler option -xCODE (where CODE is a
processor feature code) correctly.
* Added support for NVCC’s -Werror and --Werror options.
* ccache’s “Directory is not hashed if using -gz[=zlib]” tests are now
skipped for GCC 6.
* Sun Jul 19 2020 elimat@opensuse.org
- Update to version 3.7.10:
* Improved handling of profiling options. ccache should now work correctly
for profiling options like -fprofile-{generate,use}[=path] for GCC ≥ 9
and Clang as well as -fauto-profile[=path] and the Clang-specific
- fprofile-instr-{generate,use}[=path] and -fprofile-sample-{use,accurate}
options.
* ccache now copies files directly from the cache to the destination file
instead of via a temporary file. This avoids problems when using
filenames long enough to be near the file system’s filename max limit.
* When the hard-link mode is enabled, ccache now only uses hard links for
object files, not other files like dependency files. This is because
compilers unlink object files before writing to them but they don’t do
that for dependency files, so the latter can become overwritten and
therefore corrupted in the cache.
* Fixed a glitch related to hard-link mode and an empty cache.
* ccache now supports the ccache.conf file to be a symlink.
* Temporary files are now deleted immediately on signals like SIGTERM and
SIGINT instead of some time later in a cleanup phase.
* Fixed a bug that affected ccache’s -o/--set-config option for the
base_dir and cache_dir_levels keys.
* Mon Jun 22 2020 sjamgade@suse.com
- Added patch for another cleanup mechanism based on age of file:
* 0001-Add-another-cleanup-mechanism-evict-older-than.patch
* Sun Jun 07 2020 mpluskal@suse.com
- Add symlink for nvidia cuda compiler as well
* Fri Apr 03 2020 mpluskal@suse.com
- Update to version 3.7.9:
* Fixed replacing of /dev/null when building as root with hard link mode enabled and using -o /dev/null.
* Removed incorrect assertion resulting in “ccache: error: Internal error in format” when using -fdebug-prefix-map=X= with X equal to $PWD.
* Improved CUDA/NVCC support: Recognize -dc and -x cu options.
* Improved name of temporary file used in NFS-safe unlink.
- Changes for version 3.7.8:
* Use $PWD instead of the real CWD (current working directory) when checking for CWD in preprocessed output. This fixes a problem when $PWD includes a symlink part and the user has set hash_dir = false.
* Rewrote the Windows version of the lockfile routines. This should mitigate several problems with the old implementation.
* If localtime_r fails the epoch time is now logged instead of garbage.
* Improved error message when a boolean environment variable has an invalid value.
* Improved the regression fix in ccache 3.7.5 related to not passing compilation-only options to the preprocessor.
* ccache’s PCH test suite now skips running the tests if it detects broken PCH compiler support.
* Fixed unit test failure on Windows.
* Fixed “stringop-truncation” build warning on Windows.
* Improved “x_rename” implementation on Windows.
* Improved removal of temporary file when rewriting absolute paths to relative in the dependency file.
* Clarified “include_file_ctime sloppiness” in the Performance section in the manual.
* Thu Feb 06 2020 mpluskal@suse.com
- Update to version 3.7.7:
* Fixed a bug related to object file location in the dependency file (if using -MD or -MMD but not -MF and the build directory is not the same as the source directory then the object file location in the .d file would become incorrect). This fixes regression in ccache 3.7.5 introduced by the bug fix related to EDG-based compilers. Note that this removes support for EDG-based compilers again. (A better fix for this is planned for ccache 4.0.)
* Removed the unify mode since it has bugs and shortcomings that are non-trivial or impossible to fix: it doesn’t work with the direct mode, it doesn’t handle C++ raw strings correctly, it can give false cache hits for .incbin directives, it’s turned off when using -g and it can make line numbers in warning messages and __LINE__ macros incorrect.
mtime and ctime values are now stored in the manifest files only when sloppy_file_stat is set. This avoids adding superfluous manifest file entries on direct mode cache misses.
* A “Result:” line is now always printed to the log.
* The “cache miss” statistics counter will now be updated for read-only cache misses, making it consistent with the cache hit case.
* Wed Dec 18 2019 mpluskal@suse.com
- Update to version 3.7.6:
* The opt-in “file_macro sloppiness” mode has been removed so that the input file path now is always included in the direct mode hash. This fixes a bug that could result in false cache hits in an edge case when “file_macro sloppiness” is enabled and several identical source files include a relative header file with the same name but in different directories.
* Statistics files are no longer lost when the filesystem of the cache is full.
* Bail out on too hard Clang option -MJarg (in addition to the previous bailout of -MJ arg).
* Properly handle color diagnostics in the depend mode as well.
* Tue Nov 05 2019 mpluskal@suse.com
- Update to version 3.7.5:
* Added support for -MF=arg (with an extra equal sign) as understood by EDG-based compilers.
* Fixed a regression in 3.7.2 that could result in a warning message instead of an error in an edge case related to usage of “-Werror”.
* An implicit -MQ is now passed to the preprocessor only if the object file extension is non-standard. This will make it easier to use EDG-based compilers (e.g. GHS) which don’t understand -MQ. (This is a bug fix of the corresponding improvement implemented in ccache 3.4.)
* ccache now falls back to running the real compiler instead of failing fataly if an internal temporary file is missing after compilation.
* Fixed a crash if localtime returns null pointer in localtime_r replacement.
* Fixed header file dependency tracking when building ccache itself.
* Fixed warning during configure in out-of-tree build in developer mode.
* Wed Oct 16 2019 mpluskal@suse.com
- Update to version 3.7.4:
* Added support for the -gz[=type] compiler option (previously
ccache would think that “-gz” alone would enable debug
information, thus potentially including the current directory
in the hash).
* Added support for converting paths like “/c/users/...” into
relative paths on Windows.
* Mon Aug 26 2019 mpluskal@suse.com
- Update to version 3.7.3:
* The cache size (which is counted in “used disk blocks”) is now correct on filesystems that use more or less disk blocks than conventional filesystems, e.g. ecryptfs or btrfs/zfs with transparent compression. This also fixes a related problem with ccache’s own test suite when run on such file systems.
Fixed a regression in 3.7.2 when using the compiler option “-Werror” and then “-Wno-error” later on the command line.
- Changes n version 3.7.2:
* The compiler option -gdwarf* no longer forces “run_second_cpp = true”.
* Added verification that the value passed to the -o/--set-config option is valid.
* Fixed detection of precompiled headers in the depend mode.
* Bail out on too hard Clang option -ftime-trace.
* ccache now updates the correct stats file when adding/updating manifest files. This bug previously made the file and size statistics counters incorrect over time.
* Fixed warnings from Clang about unused arguments during preprocessing.
* Unknown manifest versions are now handled gracefully in --dump-manifest.
* Fixed make check with “funny” locales.
* Thu May 02 2019 mpluskal@suse.com
- Fix upstream urls
* Wed May 01 2019 l.lunak@centrum.cz
- Update URLs in the .spec file
- Update to version 3.7.1
- Changes for version 3.7.1
* Fixed a problem when using the compiler option `-MF /dev/null`.
* Long commandlines are now handled gracefully on Windows by using
the `@file` syntax to avoid hitting the commandline size limit.
* Fixed complaint from GCC 9’s `-Werror=format-overflow` when
compiling ccache itself.
- Changes for version 3.7
* Fixed crash when the debug mode is enabled and the output file is
in a non-writable directory, e.g. when the output file is `/dev/null`.
* Fixed an issue when printing very large log messages to the debug
log.
* Fixed bugs related to support for `-gsplit-dwarf`. Previously
ccache could produce an incorrect link to the `.dwo` file in the
`.o` file.
* Compilations with /dev/null as the input file are now cached.
* ccache has learned how to contruct the object filename if no `-o`
option is given and the source filename does not include a `.` or
ends with a `.`.
* Fixed a temporary file leak when the depend mode is enabled and
the compiler produces standard error output.
* Fixed a bug in the depend mode where a manifest hash only could
be associated with one set of header dependencies.
* Manifest files did not get marked as used on direct cache hits,
so the LRU cache cleanup would incorrectly remove them eventually.
This has been fixed.
* The rewriting of absolute paths into relative paths in the
dependency file has been enabled in the depend mode as well.
* ccache now ignores unknown keys in configuration files for
forward compatibility.
* Rearranged command-line options into sections in the help text.
* Documented the previously undocumented `--dump-manifest` and
`--hash-file` options (only useful for debugging ccache itself).
* Added missing documentation for the command-line option
`-k/--get-config` added in ccache 3.5.
* Renamed the `--print-config` command to `--show-config`.
* Added a new `--print-stats` command that prints statistics
counters in machine-parsable (tab-separated) format.
* ccache no longer creates a missing output directory, thus
mimicking the compiler behavior for `-o out/obj.o` when “out”
doesn’t exist.
* `-fdebug-prefix-map=ARG`, `-ffile-prefix-map=ARG` and
`-fmacro-prefix-map=ARG` are now included in the hash, but only
the part before “ARG”. This fixes a bug where compiler feature
detection of said flags would not work correctly with ccache.
* Bail out on too hard compiler option `-gtoggle`.
* Bail out on too hard Clang options `--analyze` and `-analyze`.
* Improved debug logging of file hashes in depend mode.
* Improved handling of various `-g*` options. In particular, ccache
now understands that `-g0` cancels out previous `-g* options`.
* Worked around a problem with Automake related to `.d` files when
using the hard link mode.
* Added opt-in (at configure time) support for enabling trace logs
for profiling ccache itself. See `doc/DEVELOPER.md` in the code
tree for more information
* Removed support for Fortran 77 again. Some Fortran support was
added in ccache 3.3, but the implementation did not work when
Fortran modules are involved.
* Thu Jan 31 2019 kstreitova@suse.com
- Update to version 3.6
- Changes for version 3.6
* ccache now has an opt-in ``depend mode''
* Added support for GCC's `-ffile-prefix-map` option
* Added support for multiple `-fsanitize-blacklist` arguments
* ccache now includes the environment variables `LANG`, `LC_ALL`,
`LC_CTYPE` and `LC_MESSAGES` in the hash since they may affect
localization of compiler warning messages
* Fixed a problem due to Clang overwriting the output file when
compiling an assembler file
* Clarified the manual to explain the reasoning behind the
“file_macro” sloppiness setting in a better way
* ccache now handles several levels of nonexistent directories
when rewriting absolute paths to relative
* A new sloppiness setting `clang_index_store` makes ccache skip
the Clang compiler option `-index-store-path` and its argument
when computing the manifest hash
* Rename sloppiness `no_system_headers` to `system_headers` for
consistency with other options
* The GCC variables “DEPENDENCIES_OUTPUT” and “SUNPRO_DEPENDENCIES”
are now supported correctly.
* The algorithm that scans for `__DATE_` and `__TIME__` tokens in
the hashed source code now doesn't produce false positives for
tokens where `__DATE__` or `__TIME__` is a substring
- Changes for version 3.5.1
* Added missing getopt_long.c source file to release archive
* Fixed (harmless) compiler warnings when building ccache object
files
* CFLAGS is no longer passed to the linker when linking ccache
* Improved development mode build flags
* Mon Oct 22 2018 mpluskal@suse.com
- Make sure bundled zlib is not used
- Make building more verbose
* Mon Oct 22 2018 sean@suspend.net
- Update to version 3.5
* Added a boolean debug (CCACHE_DEBUG) configuration option
* Renamed CCACHE_CC to CCACHE_COMPILER
* Added a new command-line option -k/--get-config
* Improved performance substantially when using hash_dir = false
* Renamed "stats zero time" to "stats zeroed"
* Added file_state_matches_ctime option to disable ctime check
* Wed Jul 11 2018 mpluskal@suse.com
- Enable testsuite
* Tue Apr 17 2018 kstreitova@suse.com
- Update to version 3.4.2 [bsc#1089879]
* The cleanup algorithm has been fixed to not misbehave when
files are removed by another process while the cleanup process
is running. Previously, too many files could be removed from
the cache if multiple cleanup processes were triggered at the
same time, in extreme cases trimming the cache to a much
smaller size than the configured limits.
* Correctly hash preprocessed headers located in a
“.gch directory”. Previously, ccache would not pick up changes
to such precompiled headers, risking false positive cache hits.
* Fixed build failure when using the bundled zlib sources.
* ccache 3.3.5 added a workaround for not triggering Clang errors
when a precompiled header’s dependency has an updated timestamp
(but identical content). That workaround is now only applied
when the compiler is Clang.
* Made it possible to perform out-of-source builds in dev mode
again.
- AUTHORS.*, MANUAL.* and NEWS.* files are now located in the doc
directory
* Thu Mar 15 2018 mpluskal@suse.com
- Update to version 3.4.1:
* Fixed printing of version number in ccache --version.
- Changes for version 3.4.0:
* The compiler option form --sysroot arg is now handled like the
documented --sysroot=arg form.
* Added support for caching .su files generated by GCC flag
- fstack-usage.
* ccache should now work with distcc’s “pump” wrapper.
* The optional unifier is no longer disabled when the direct mode
is enabled.
* Added support for nvcc compiler options --compiler-bindir/-ccbin,
- -output-directory/-odir and --libdevice-directory/-ldir.
* Boolean environment variable settings no longer accept the
following (case-insensitive) values: 0, false, disable and no.
All other values are accepted and taken to mean “true”. This is
to stop users from setting e.g. CCACHE_DISABLE=0 and then
expect the cache to be used.
* Improved support for run_second_cpp = false: If combined with
passing -fdirectives-only (GCC) or frewrite-includes (Clang) to
the compiler, diagnostics warnings and similar will be correct.
* An implicit -MQ is now passed to the preprocessor only if the
object file extension is non-standard. This should make it
easier to use EDG-based compilers (e.g. GHS) which don’t
understand -MQ.
* ccache now treats an unreadable configuration file just like a
missing configuration file.
* Documented more pitfalls with enabling hard_links
(CCACHE_HARDLINK).
* Documented caveats related to colored warnings from compilers.
* File size and number counters are now updated correctly when
files are overwritten in the cache, e.g. when using
CCACHE_RECACHE.
* run_second_cpp is now forced for nvcc.
* Fixed how the nvcc options -optf and -odir are handled.
* Sat Feb 03 2018 avindra@opensuse.org
- Update to version 3.3.6:
* Improved instructions on how to get cache hits between different
working directories.
- Changes for version 3.3.5:
* Documented how automatic cache cleanup works.
* Fixed a regression where the original order of debug options
could be lost. This reverts the “Improved parsing of -g*
options” feature in ccache 3.3.
* Multiple -fdebug-prefix-map options should now be handled
correctly.
* Fixed matching of directories in the ignore_headers_in_manifest
configuration option.
* Fixed detection of missing argument to -opt/--options-file.
* ccache now bails out when building a precompiled header if any
of the corresponding header files have an updated timestamp.
This fixes complaints from clang.
* Fixed a bug related to erroneously storing a dependency file
with absolute paths in the cache on a preprocessed hit.
* ccache -c/--cleanup now works like documented: it just
recalculates size counters and trims the cache to not exceed
the max size and file number limits. Previously, the forced
cleanup took “limit_multiple” into account, so that ccache
- c/--cleanup by default would trim the cache to 80% of the max
limit.
* ccache no longer ignores linker arguments for clang since clang
warns about them.
* Plugged a couple of file descriptor leaks.
* Fixed a bug where ccache would skip hashing the compiler
argument following a -fno-working-directory,
- fworking-directory, -nostdinc, -nostdinc++, -remap or
- trigraphs option in preprocessor mode.
- cleanup with spec-cleaner
* Wed Apr 05 2017 mpluskal@suse.com
- Update to version 3.3.4:
* Documented the different cache statistics counters.
* Fixed a regression in ccache 3.3 related to potentially bad
content of dependency files when compiling identical source
code but with different source paths. This was only partially
fixed in 3.3.2 and reverts the new “Names of included files are
no longer included in the hash of the compiler’s preprocessed
output” feature in 3.3.
* Corrected statistics counter for -optf/--options-file failure.
* Fixed undefined behavior warnings in ccache found by
- fsanitize=undefined.
* Thu Jan 19 2017 asn@cryptomilk.org
- Update to version 3.3.3
* ccache now detects usage of .incbin assembler directives in
the source code and avoids caching such compilations.
- Changes for version 3.3.2:
* Fixed a regression in ccache 3.3 related to potentially bad
content of dependency files when compiling identical source
code but with different source paths.
* Fixed a regression in ccache 3.3.1: ccache could get confused
when using the compiler option -Wp, to pass multiple options
to the preprocessor, resulting in missing dependency files
from direct mode cache hits.
* Sun Sep 11 2016 mpluskal@suse.com
- Update to version 3.3.1:
* Fixed a problem in the “multiple -arch options” support
introduced in 3.3. When using the direct mode (the default),
different combinations of -arch options were not detected
properly.
* Fixed an issue when compiler option -Wp,-MT,path is used
instead of -MT path (and similar for -MF, -MP and -MQ) and
run_second_cpp (CCACHE_CPP2) is enabled.
- Changes for version 3.3.0:
* A C99-compatible compiler is now required to build ccache.
* The configuration option run_second_cpp (CCACHE_CPP2) now
defaults to true. This improves ccache’s out-of-the-box
experience for compilers that can’t compile their own
preprocessed output with the same outcome as if they compiled
the real source code directly, e.g. newer versions of GCC and
Clang.
* The configuration option hash_dir (CCACHE_HASHDIR) now defaults
to true.
* Added a new ignore_headers_in_manifest configuration option,
which specifies headers that should be ignored in the direct
mode.
* Added a new prefix_command_cpp (CCACHE_PREFIX_CPP) configuration
option, which specifies one or several prefixes to add to the
command line ccache uses when invoking the preprocessor.
* Added a new limit_multiple (CCACHE_LIMIT_MULTIPLE) configuration
option, which specifies how much of the cache to remove when
cleaning.
* Added a new keep_comments_cpp (CCACHE_COMMENTS) configuration
option, which tells ccache not to discard the comments before
hashing preprocessor output. This can be used to check
documentation with -Wdocumentation.
* Added a new sloppiness option no_system_headers, which tells
ccache not to include system headers in manifest files.
* Added a new statistics counter that tracks the number of
performed cleanups due to the cache size being over the limit.
The value is shown in the output of “ccache -s”.
* Added support for relocating debug info directory using
- fdebug-prefix-map. This allows for cache hits even when
hash_dir is used in combination with base_dir.
* Added a new “cache hit rate” field to the output of “ccache -s”.
* Added support for caching compilation of assembler code produced
by e.g. “gcc -S file.c”.
* Added support for cuda including the -optf/--options-file option.
* Added support for Fortran 77.
* Added support for multiple -arch options to produce "fat binaries".
* Multiple identical -arch arguments are now handled without bailing.
* The concatenated form of some long compiler options is now
recognized, for example when using -isystemPATH instead of
- isystem PATH.
* If hard-linking is enabled and but fails (e.g. due to
cross-device linking), ccache now falls back to copying instead
of running the compiler.
* Made the hash_dir option only have effect when generating debug
info.
* ccache now knows how to convert absolute paths to relative
paths inside dependency files when using base_dir.
* Improved parsing of -g* options.
* Made ccache understand -Wp,-D* options.
* ccache now understands the undocumented -coverage (only one
dash) GCC option.
* Names of included files are no longer included in the hash of
the compiler’s preprocessed output. This leads to more
potential cache hits when not using the direct mode.
* Increased buffer size used when reading file data. This
improves performance slightly.
- Changes for version 3.2.8:
* Bail out on too hard compiler option -P.
* Fixed clang test suite when running on Linux.
* Fixed build and test for MinGW32 and Windows.
- Add fortran amd objc symlinks
* Fri Aug 26 2016 tchvatal@suse.com
- Version update to 3.2.7:
- Fixed build problem on QNX, which lacks ``SA_RESTART''.
- Bail out on compiler option `-fstack-usage` since it creates a `.su` file
which ccache currently doesn't handle.
- Fixed a bug where (due to ccache rewriting paths) the compiler could choose
incorrect include files if `CCACHE_BASEDIR` is used and the source file path
is absolute and is a symlink.
- Fixed a bug which could lead to false cache hits for compiler command lines
with a missing argument to an option that takes an argument.
- ccache now knows how to work around a glitch in the output of GCC 6's
preprocessor.
* Fri Aug 26 2016 tchvatal@suse.com
- Create basic symlinks for clang and regular cc calls for ccache
* this makes it easier to use ccache with osc build
* Fri Jul 08 2016 mpluskal@suse.com
- Small spec file cleanup
- Disable testsuite as it is not reliable in OBS
* Thu Apr 28 2016 idonmez@suse.com
- Update to 3.2.5
* Only pass clang-specific -stdlib= to the preprocessor.
* Improved handling of stale NFS handles.
* Made it harder to misinterpret documentation of boolean
environment settings' semantics.
* Corrected "Performance" section in the manual regarding __DATE_,
__TIME__ and __FILE__ macros.
* Don’t (try to) update manifest file in “read-only” and
“read-only direct” modes.
* Fixed a bug in caching of stat system calls in “file_stat_matches
sloppiness mode”.
* Fixed bug in hashing of clang plugins, leading to unnecessary
cache misses.
* Fixed --print-config to show “pch_defines sloppiness”.
* Thu Oct 08 2015 mpluskal@suse.com
- Update to 3.2.4
* Fixed build error related to zlib on systems with older make
versions (regression in ccache 3.2.3).
* Made conversion-to-bool explicit to avoid build warnings (and
potential runtime errors) on legacy systems.
* Improved signal handling: Kill compiler on SIGTERM; wait for
compiler to exit before exiting; die appropriately.
* Minor fixes related to Windows support.
* The correct compression level is now used if compression is
requested.
* Fixed a bug where cache cleanup could be run too early for
caches larger than 64 GiB on 32-bit systems.
* Sat Aug 22 2015 astieger@suse.com
- update to 3.2.3:
* Added support for compiler option -gsplit-dwarf.
* Support external zlib in nonstandard directory.
* Avoid calling exit() inside an exit handler.
* Let exit handler terminate properly.
* Bail out on compiler option --save-temps in addition to
- save-temps.
* Only log "Disabling direct mode" once when failing to read
potential include files.
* Fri May 22 2015 mpluskal@suse.com
- Update to 3.2.2
* Added support for `CCACHE_COMPILERCHECK=string:<value>`. This
is a faster alternative to `CCACHE_COMPILERCHECK=<command>` if
the command's output can be precalculated by the build system.
* Add support for caching code coverage results (compiling for
gcov).
* Fixed bug which could result in false cache hits when source
code contains `'"'` followed by `" /*"` or `" //"` (with
variations).
* Made hash of cached result created with and without
`CCACHE_CPP2` different. This makes it possible to rebuild
with `CCACHE_CPP2` set without having to clear the cache to
get new results.
* Don't try to reset a non-existing stats file. This avoids
``No such file or directory'' messages in the ccache log when
the cache directory doesn't exist.
* Fixed a bug where ccache deleted clang diagnostics after
compiler failures.
* Avoid performing an unnecessary copy of the object file on a
cache miss.
* Bail out on too hard compiler option `-fmodules`.
* Bail out on too hard compiler option `-fplugin=libcc1plugin`
(interaction with GDB).
* Fixed build error when compiling ccache with recent clang
versions.
* Removed signal-unsafe code from signal handler.
* Corrected logic for when to output cached stderr.
* Wipe the whole cached result on failure retrieving a cached
file.
* Fixed build error when compiling ccache with recent clang
versions.
* Fri May 15 2015 mvyskocil@opensuse.org
- Add the compat symlinks for gcc/g++ to libdir, so prepending
libdir to PATH enabled ccache by default
* Fri Feb 20 2015 mpluskal@suse.com
- Add gpg signature
- Remove ccache-gcc48.patch and xclang.patch (both are already
present in current release)
- On i586, use only small testsuite (quicktest) full testsuite
fails (https://bugzilla.samba.org/show_bug.cgi?id=11109)
- Update to 3.2.1:
* Added support for configuring ccache via one or several
configuration files instead of via environment variables.
Environment variables still have priority but are no longer
the recommended way of customizing ccache behavior. See the
manual for more information.
* Added support for compiler error/warning messages with color.
* Made creation of temporary directories and cache directories
smarter to avoid unnecessary stat calls.
* Improved efficiency of the algorithm that scans for
__DATE_ and __TIME__ tokens in the hashed source code.
* Added support for several binaries (separated by space) in
CCACHE_PREFIX.
* The -c option is no longer passed to the preprocessor.
This fixes problems with clang and Solaris’s C++ compiler.
* ccache no longer passes preprocessor options like -D and -I to
the compiler when compiling preprocessed output. This fixes
warnings emitted by clang.
* Compiler options -fprofile-generate, -fprofile-arcs,
- fprofile-use and -fbranch-probabilities are now handled
without bailing.
* Added support for clang’s --serialize-diagnostic option,
storing the diagnostic file (.dia) in the cache.
* Added support for precompiled headers when using clang.
* Changed the -x language option to use the new objective C
standard for GCC and clang.
* On a cache miss, ccache now instructs the compiler to create
the object file at the real destination and then copies the
file into the cache instead of the other way around. This is
needed to support compiler options like -fprofile-arcs
and --serialize-diagnostics.
* ccache now checks that included files' ctimes aren’t too new.
This check can be turned off by adding include_file_ctime
to the “ccache sloppinessâhe filename part of options
like -Wp,-MDfilename is no longer included in the hash
since the filename doesn’t have any bearing on the result.
* Added a “read-only directâefault cache size is now 5 GB
(was previously 1 GiB).
* Added support for @file and -@file arguments (reading options
from a file).
* Bail out on too hard compiler option -Wp,-P.
* Optimized MD4 calculation code on little-endian systems.
* Various improvements and fixes on win32.
* Improved logging to the ccache log file.
* Added --dump-manifest command-line option for debugging purposes.
* Added --with-bundled-zlib configure option.
* Upgraded bundled zlib to version 1.2.8.
* Improved dev.mk to be more platform independent.
* Made the test suite work with clang and gcc-llvm on OS X.
* Various other improvements of the test suite.
