- 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.

- 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.

OBS-URL: https://build.opensuse.org/package/show/devel:tools:building/ccache?expand=0&rev=133
- 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.

- 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

OBS-URL: https://build.opensuse.org/package/show/devel:tools:building/ccache?expand=0&rev=129
- 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
OBS-URL: https://build.opensuse.org/request/show/1005766
OBS-URL: https://build.opensuse.org/package/show/devel:tools:building/ccache?expand=0&rev=125
* 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).
OBS-URL: https://build.opensuse.org/package/show/devel:tools:building/ccache?expand=0&rev=121
- 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.

OBS-URL: https://build.opensuse.org/package/show/devel:tools:building/ccache?expand=0&rev=115
* 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.
OBS-URL: https://build.opensuse.org/package/show/devel:tools:building/ccache?expand=0&rev=104
* 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.
OBS-URL: https://build.opensuse.org/package/show/devel:tools:building/ccache?expand=0&rev=101
Another attempt, with ccache-4.1.tar.xz.asc added.
This fixes https://github.com/ccache/ccache/issues/711, which prevented ccache 4.0 being accepted into Factory.
- 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.
OBS-URL: https://build.opensuse.org/request/show/850291
OBS-URL: https://build.opensuse.org/package/show/devel:tools:building/ccache?expand=0&rev=99
* 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
OBS-URL: https://build.opensuse.org/package/show/devel:tools:building/ccache?expand=0&rev=98
- 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.
OBS-URL: https://build.opensuse.org/request/show/821771
OBS-URL: https://build.opensuse.org/package/show/devel:tools:building/ccache?expand=0&rev=94
* 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.
OBS-URL: https://build.opensuse.org/package/show/devel:tools:building/ccache?expand=0&rev=85
* 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.
OBS-URL: https://build.opensuse.org/package/show/devel:tools:building/ccache?expand=0&rev=83
* 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.
OBS-URL: https://build.opensuse.org/package/show/devel:tools:building/ccache?expand=0&rev=81
* 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.
OBS-URL: https://build.opensuse.org/package/show/devel:tools:building/ccache?expand=0&rev=79
* 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.
OBS-URL: https://build.opensuse.org/package/show/devel:tools:building/ccache?expand=0&rev=76
* 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.
OBS-URL: https://build.opensuse.org/package/show/devel:tools:building/ccache?expand=0&rev=74
- 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
OBS-URL: https://build.opensuse.org/request/show/670323
OBS-URL: https://build.opensuse.org/package/show/devel:tools:building/ccache?expand=0&rev=69
- 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.
