5 years agostats: Fix statistics update with full filesystem
Russell King [Thu, 31 Oct 2019 16:30:22 +0000 (16:30 +0000)] 
stats: Fix statistics update with full filesystem

The statistics file update does not check for write errors correctly
as stdio files are normally buffered.  This means that data can be
written to the stdio buffer but not written out until fclose().
Hence, it is imperative that the fclose() return value is also
checked.

If either fprintf() or fclose() fail, clean up the temporary file,
rather than littering the filesystem with needless temporary files.

After 5d8585b5 (#312), arguments that are not considered affecting the
preprocessor output won’t be passed to the preprocessor. -Werror and
-Wno-error are also not passed to the preprocessor so that options not

errors. This was a workaround for Clang complaining about unused
arguments in the preprocessor step performed by ccache.

However, it also introduced a regression: -Werror and the other options
were excluded from the hash as well. This means that

  cc -c file_with_warnings.c

would be cached by ccache, including the warning message. A later

  cc -Werror -c file_with_warnings.c

call would then be a cache hit, resulting in a compilation warning
instead of an error.

Don’t pass -Werror and compilation-only options to the preprocessor

Clang emits warnings when it sees unused options, so when ccache runs
the Clang preprocessor separately, options that are not used by the
preprocessor will produce warnings. This means that the user may get
warnings which would not be present when not using ccache. And if

Fix PCH detection in depend mode (+test improvements) (#427)

* do not refer to Clang's PTH in tests

The PTH feature has been removed (https://reviews.llvm.org/D54547)
and according to the commit it has never really been used. Maybe this
made sense somewhen in the past, but now those .pth files must be PCHs
internally. This commit actually just changes the .pth extensions
to .pch to avoid confusion, technically nothing should change
except for filenames.

* try to share PCH tests between GCC and Clang

Clang is supposed to be a drop-in for GCC, so in general it should
be able to handle everything GCC can. That's not completely true
in practice, there are differences, but it doesn't make sense
to completely duplicate a testcase just because there are some
differences. So start creating a shared common base for the PCH
tests and do separately only tests that act differently.

* more sharing of PCH tests between GCC and Clang

There's e.g. no need to do all kinds of complex tests with both
.gch and .pch with Clang, except for checking that Clang finds
one of them if none is specified explicitly.

* log also when pch usage is detect from pragma pch_preprocess

* try harder to verify in tests that ccache detects PCH changes

Some of the tests did that, e.g. those 'file changed', but e.g. the cached
.gch creation did not. So try to intentionally change the .gch/.h and test
that it leads to a cache miss. Otherwise there might be a hit simply
because ccache failed to detect PCH usage and ignores the .gch completely.

* clean up #include vs -fpch-preprocess in pch tests

As the manpage says, -fpch-preprocess is needed only with the #include
form, otherwise it's pointless.

* do not mention sloppiness in pch tests, only no sloppiness

Since sloppiness is normally required, so no point in stating the obvious.

* test also -include-pch with clang

* hash also pch introduced only using -include

GCC does not output the pch in the .d dependencies file, so without
this there would be false cache hits.

* be consistent about sloppiness in pch tests

create pch -> pch_defines
use pch -> time_macros

* test CCACHE_PCH_EXTSUM more thoroughly and also with -include

* pch test for .gch file being in an extra directory

* doc corrections for how to use PCH with ccache

- ccache will fail to properly detect that -include a.h means using
  a.h.gch if it requires using path from -I (they are not searched)
- -fpch-preprocess does nothing with Clang, it doesn't output
  pragma GCC pch_preprocess and so #include form for PCHs doesn't work

this is useful for determining the length of the generated argument string

* correctly handle @file syntax on Windows

the @file syntax means that the process reads command arguments from the
specified file. this is commonly used in order to shorten commands which
would otherwise be longer than the maximum length limit: many build systems
do this in all cases to avoid hitting this limit.

when a command exceeds 8192 characters on on Windows, ccache now writes
the parsed/modified arguments to a tmpfile and then runs the command using
that tmpfile with @tmpfile in order to preserve this mechanism and avoid hitting
the length limit

bytes (depending on the number of previously hashed bytes) of the data
