New features and improvements:
- 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).
Bug fixes:
- 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.
With systemd 219, this is fine because systemd will cause the new
journald to re-use the file descriptors of the old one. So existing
connections to the journal are unaffected.
This shuts up this error from dbus:
May 11 13:52:16 machine dbus-daemon[259]: Unknown username "systemd-network" in message bus configuration file
May 11 13:52:16 machine dbus-daemon[259]: Unknown username "systemd-resolve" in message bus configuration file
which happens because the D-Bus config for networkd/resolved is
enabled unconditionally, and we don't have an easy way to turn it off.
Commit c5d13d4fe96674a4fcb04b54ea552847302e13ee caused libmicrohttpd
to be not so micro anymore, increasing its closure size from 40 MiB to
283 MiB, which is annoying for packages like systemd that use it. So
don't enable httpd/spdy support by default.
