Changelog for ccache-4.3-2.1.i586.rpm :

* Wed May 12 2021 Andreas Stieger - 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 Martin Pluskal - 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 Martin Pluskal - 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 - 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 Martin Pluskal - 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 Matthias Eliasson - 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 Matthias Eliasson - 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 Sumit Jamgade - Added patch for another cleanup mechanism based on age of file:
* 0001-Add-another-cleanup-mechanism-evict-older-than.patch
* Sun Jun 07 2020 Martin Pluskal - Add symlink for nvidia cuda compiler as well
* Fri Apr 03 2020 Martin Pluskal - 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 Martin Pluskal - 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 Martin Pluskal - 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 Martin Pluskal - 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 Martin Pluskal - 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 Martin Pluskal - 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 Martin Pluskal - Fix upstream urls
* Wed May 01 2019 - 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 `AATTfile` 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 kstreitovaAATTsuse.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 Martin Pluskal - Make sure bundled zlib is not used- Make building more verbose
* Mon Oct 22 2018 seanAATTsuspend.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 mpluskalAATTsuse.com- Enable testsuite
* Tue Apr 17 2018 kstreitovaAATTsuse.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 mpluskalAATTsuse.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 avindraAATTopensuse.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
