Makefile: run coccicheck on more source files
Before, when running the "coccicheck" target, only the source files which were being compiled would have been checked by Coccinelle. However, just because we aren't compiling a source file doesn't mean we have to exclude it from analysis. This will allow us to catch more mistakes, in particular ones that affect Windows-only sources since Coccinelle currently runs only on Linux. Make the "coccicheck" target run on all C sources except for those that are taken from some third-party source. We don't want to patch these files since we want them to be as close to upstream as possible so that it'll be easier to pull in upstream updates. When running a build on Arch Linux with no additional flags provided, after applying this patch, the following sources are now checked: * block-sha1/sha1.c * compat/access.c * compat/basename.c * compat/fileno.c * compat/gmtime.c * compat/hstrerror.c * compat/memmem.c * compat/mingw.c * compat/mkdir.c * compat/mkdtemp.c * compat/mmap.c * compat/msvc.c * compat/pread.c * compat/precompose_utf8.c * compat/qsort.c * compat/setenv.c * compat/sha1-chunked.c * compat/snprintf.c * compat/stat.c * compat/strcasestr.c * compat/strdup.c * compat/strtoimax.c * compat/strtoumax.c * compat/unsetenv.c * compat/win32/dirent.c * compat/win32/path-utils.c * compat/win32/pthread.c * compat/win32/syslog.c * compat/win32/trace2_win32_process_info.c * compat/win32mmap.c * compat/winansi.c * ppc/sha1.c This also results in the following source now being excluded: * compat/obstack.c Instead of generating $(FOUND_C_SOURCES) from a `$(shell $(FIND_SOURCE_FILES))` invocation, an alternative design was considered which involved converting $(FIND_SOURCE_FILES) into $(SOURCE_FILES) which would hold a list of filenames from the $(FIND_SOURCE_FILES) invocation. We would simply filter `%.c` files into $(ALL_C_SOURCES). $(SOURCE_FILES) would then be passed directly to the etags, ctags and cscope commands. We can see from the following invocation $ git ls-files '*.[hcS]' '*.sh' ':!*[tp][0-9][0-9][0-9][0-9]*' ':!contrib' | wc -c 12779 that the number of characters in this list would pose a problem on platforms with short command-line length limits (such as CMD which has a max of 8191 characters). As a result, we don't perform this change. However, we can see that the same issue may apply when running Coccinelle since $(COCCI_SOURCES) is also a list of filenames: if ! echo $(COCCI_SOURCES) | xargs $$limit \ $(SPATCH) --sp-file $< $(SPATCH_FLAGS) \ >$@+ 2>$@.log; \ This is justified since platforms that support Coccinelle generally have reasonably long command-line length limits and so we are safe for the foreseeable future.
