* test: Disable "output file failure" test for unsupported filesystemJoel Rosdahl2022-08-271-11/+16
| | | | | | | | | | The "Failure to write output file" test assumes that the filesystem supports read-only directories. Improve this by probing this assumption before running the test. Fixes #1150. (cherry picked from commit 553fc98f846bf6de1566e8526f4a779b70d814c8)

* fix: Always rewrite dependency file if base_dir is usedJoel Rosdahl2022-08-204-16/+0
| | | | | | | | | | | | | | | | | | | [1] added the has_absolute_include_headers variable as a performance optimization for base_dir/CCACHE_BASEDIR so that the dependency file only has to be parsed/rewritten when necessary. This is based on the assumption that if no include file has an absolute path then no rewrite is needed, but apparently Clang can insert other paths into the dependency file as well, for instance the asan_blacklist.txt file when using -fsanitize=address. Fix this by simply always parsing the dependency file when base_dir is active. Fixes #1128.

* fix: Avoid false success for -fcolor-diagnostics probe with GCCJoel Rosdahl2022-08-204-51/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Ccache will produce a false hit in the following scenario, if "cc" is GCC without being a symlink to "gcc": 1. ccache cc -c example.c # adds a cache entry 2. ccache cc -c example.c -fcolor-diagnostics # unexpectedly succeeds (Most major Linux distributions install cc as a symlink to gcc, and then the problem doesn't show up since ccache then is able to guess that the compiler is GCC.) This bug was introduced by [1] which tried to make yet another tweak of the color diagnostics guessing/probing by no longer rejecting -fcolor-diagnostics for an unknown compiler, based on the assumption that the probing call (speculatively adding -fdiagnostics-color) is only made when we have guessed a GCC compiler. Unfortunately, this broke the fix in [2] when the compiler is unknown. All of this is inherently brittle and I don't see any good way to make it better with the current compiler guessing approach and adding options speculatively. The cure is to start doing proper compiler identification instead (#958). Until that is done, the only reasonable fix is to avoid doing anything related to color diagnostics flags when the compiler is unknown. This means that an unknown compiler from now on won't produce colors when used via ccache even if the compiler actually is GCC or Clang.

* fix: Use a cleanup stamp instead of directory timestamp for cleanupJoel Rosdahl2022-08-203-27/+21
| | | | | | | | | | | In order to know when to clean up the temporary directory, ccache checks mtime of $CCACHE_DIR and updates it to "now" on cleanup. This doesn't work well when the configuration file is modified often since that also updates the same mtime. Fix this by using a separate cleanup stamp file instead. (cherry picked from commit ec27506da3a03e0f5bf5f80494174fcdd9a43b0e)
* fix: Clean up temporary dir if it's left the defaultJoel Rosdahl2022-08-203-6/+6
| | | | | | | | | | | Cleanup of the temporary directory is done if it is $CCACHE_DIR/tmp, which used to be the default until [1] where the default was changed to /run/user/$UID/ccache-tmp. Improve this so that cleanup happens if the temporary directory is equal to the default regardless of the default.

* fix: Add and use Util::{get,set}_umask functionsJoel Rosdahl2022-08-205-7/+22
| | | | | | | | | | | | | | | Using mode_t mask = umask(0); umask(mask); to retrieve the current umask isn't thread-safe. This messed up file permissions when recompressing the cache. Fix this by caching the last set value and always using Util::{get,set}_umask to get and set the umask. (cherry picked from commit f8f1c35344e37bc52c9fe71daebb5b378bd353f3)
* fix: Retain mtime/atime for recompressed filesJoel Rosdahl2022-08-201-3/+5

* fix: Use correct umask when populating primary cache from secondaryJoel Rosdahl2022-08-203-17/+12
| | | | | | | | | | | | | | | Util::get_umask retrieves the process's umask and caches it to avoid some system calls. This doesn't interact well now when using UmaskScope to change umask temporarily since Util::get_umask then only sometimes returns the correct value. This leads to the incorrect umask being used when writing cache entries to the primary storage for secondary storage hits. Fix this by not caching the umask system call. Closes #1087. (cherry picked from commit 6484cdfa0f22214d91cd61562f48d4d9060d2533)
* fix: Create temporary file with cpp extension instead of hard linkingJoel Rosdahl2022-08-205-28/+39
| | | | | | | | | | | | | | | | | [1] added a suitable file extension to the temporary file used for capturing the preprocessed output by creating a hard link. This fails when the temporary directory is on a file system that doesn't support hard links. Fix this by making it possible to pass a suffix to TemporaryFile and passing the proper cpp suffix for the tmp stdout file instead of creating a hard link as an alias. [1]: 4da9f2b474b7ee39cd54ab4261f90936f3c944ec Closes #1079. (cherry picked from commit e55d7e6d97e65580e21389b1b5b69d35421720be)
