If compilation doesn\(cqt work with ccache, but it works without it, one possible reason is that the compiler can\(cqt compile preprocessed output correctly\&. A workaround that may work is to set \fBCCACHE_CPP2\fR\&. This will make cache misses slower, though, so it is better to find and fix the root cause\&.

-It should be noted that ccache is susceptible to general storage problems\&. If a bad object file sneaks into the cache for some reason, it will of course stay bad\&. Some possible reasons for erroneous object files are bad hardware (disk drive, disk controller, memory, etc), buggy drivers or file systems, a bad \fBCCACHE_PREFIX\fR command or compiler wrapper\&. If this happens, you can either find out which object file is broken by reading the debug log and then delete the bad object file from the cache, or you can simply clear the whole cache with \fBccache \-C\fR if you don\(cqt mind losing other cached results\&.

- - Corrupt manifest files are now removed so that they won't block direct
- mode hits.
- - ccache now copes with file systems that don't know about symbolic links.
- - The file handle in now correctly closed on write error when trying to
- create a cache dir tag.
-- Spec file updates:
- - Changes based on rpmdevtools templates and spec-cleaner run.
- - Updated Summary: and %description.
- - Made it compile with external zlib instead of the bundled copy.
- - Added also the html files in the %doc section.
-
--------------------------------------------------------------------
-Mon Nov 29 09:56:02 UTC 2010 - puzel@novell.com

- handled correctly
- - improved documentation on which information is included in the
- hash sum
- - made the 'too new header file' test case work on file systems
- with unsynchronized clocks
- - the test suite now also works on systems that lack a /dev/zero
-
--------------------------------------------------------------------

-
-- update to ccache-3.1.1
- - ccache now falls back to preprocessor mode when a non-regular
- include file (device, socket, etc) has been detected so that
- potential hanging due to blocking reads is avoided.
- - CRC errors are now detected when decompressing compressed files
- in the cache.
- - Fixed potential object file corruption race on NFS.
- - Minor documentation corrections.
- - Fixed configure detection of ar.

-
-- update to ccache-3.1
- - features:
- - Added support for hashing the output of a custom command
- (e.g. `$compiler --version`) to identify the compiler
- instead of stat-ing or hashing the compiler binary.
- - Added support for caching compilations that use precompiled
- headers.
- - Locking of the files containing statistics counters is now
- done using symlinks instead of POSIX locks.
- - Manifest files are now updated without the need of taking
- locks.

- used.
- - Made `--ccache-skip` work for all options.
- - EINTR is now handled correctly.

-
-- update to ccache-3.0.1
- - bugfixes:
- - The statistics counter ``called for link'' is now correctly
- updated when linking with a single object file.
- - Fixed a problem with out-of-source builds.
-
--------------------------------------------------------------------
-Mon Jul 12 11:43:54 UTC 2010 - puzel@novell.com
-
-- update to ccache-3.0
- - notable changes:
- - The way the hashes are calculated has changed, so you won't get
- cache hits for compilation results stored by older ccache
- versions. Because of this, you might as well clear the old
- cache directory with `ccache --clear` if you want, unless you
- plan to keep using an older ccache version.
- - ccache now has a ``direct mode'' where it computes a hash of
- the source code (including all included files) and compiler
- options without running the preprocessor. By not running the
- preprocessor, CPU usage is reduced; the speed is somewhere
- between 1 and 5 times that of ccache running in traditional
- mode, depending on the circumstances. The speedup will be
- higher when I/O is fast (e.g., when files are in the disk
- cache). The direct mode can be disabled by setting
- +CCACHE_NODIRECT+.
- - Support has been added for rewriting absolute paths to relative
- paths when hashing, in order to increase cache hit rate when
- building the same source code in different directories even
- when compiling with `-g` and when using absolute include
- directory paths. This is done by setting the `CCACHE_BASEDIR`
- environment variable to an absolute path that specifies which
- paths to rewrite.
- - Object files are now optionally stored compressed in the cache.
- The runtime cost is negligible, and more files will fit in the
- ccache directory and in the disk cache. Set `CCACHE_COMPRESS`
- to enable object file compression. Note that you can't use
- compression in combination with the hard link feature.
- - A `CCACHE_COMPILERCHECK` option has been added. This option
- tells ccache what compiler-identifying information to hash to
- ensure that results retrieved from the cache are accurate.
- Possible values are: none (don't hash anything), mtime (hash
- the compiler's mtime and size) and content (hash the content of
- the compiler binary). The default is mtime.
