From 552fc5016f16d2f2ed465278f073fa03bc1851a7 Mon Sep 17 00:00:00 2001 From: Denton Liu Date: Wed, 4 Sep 2019 04:09:45 -0700 Subject: [PATCH 1/2] mingw: apply array.cocci rule After running Coccinelle on all sources inside compat/ that were created by us[1], it was found that compat/mingw.c violated an array.cocci rule in two places and, thus, a patch was generated. Apply this patch so that all compat/ sources created by us follows all cocci rules. [1]: Do not run Coccinelle on files that are taken from some upstream because in case we need to pull updates from them, we would like to have diverged as little as possible in order to make merging updates simpler.

In the last commit, we determined the files which taken from an upstream so we can exclude them and run spatch on the remainder. This was the Coccinelle patch used: @@ type T; identifier f; @@ - extern T f(...); and it was run with: $ git ls-files compat/\*\*.{c,h} | xargs spatch --sp-file contrib/coccinelle/noextern.cocci --in-place $ git checkout -- \ compat/regex/ \ compat/inet_ntop.c \ compat/inet_pton.c \ compat/nedmalloc/ \ compat/obstack.{c,h} \ compat/poll/ Coccinelle has some trouble dealing with `__attribute__` and varargs so we ran the following to ensure that no remaining changes were left behind: $ git ls-files compat/\*\*.{c,h} | xargs sed -i'' -e 's/^\(\s*\)extern \([^(]*([^*]\)/\1\2/' $ git checkout -- \ compat/regex/ \ compat/inet_ntop.c \ compat/inet_pton.c \ compat/nedmalloc/ \ compat/obstack.{c,h} \ compat/poll/ Signed-off-by: Denton Liu Acked-by: Johannes Schindelin Signed-off-by: Junio C Hamano --- compat/mingw.h | 6 +++--- compat/win32/pthread.h | 6 +++--- 2 files changed, 6 insertions(+), 6 deletions(-) diff --git a/compat/mingw.h b/compat/mingw.h index a03e40e6e2..9ad204c57c 100644 --- a/compat/mingw.h +++ b/compat/mingw.h @@ -11,7 +11,7 @@ typedef _sigset_t sigset_t; #undef _POSIX_THREAD_SAFE_FUNCTIONS #endif -extern int mingw_core_config(const char *var, const char *value, void *cb); +int mingw_core_config(const char *var, const char *value, void *cb); #define platform_core_config mingw_core_config /* @@ -443,7 +443,7 @@ static inline void convert_slashes(char *path) *path = '/'; } #define PATH_SEP ';' -extern char *mingw_query_user_email(void); +char *mingw_query_user_email(void); #define query_user_email mingw_query_user_email #if !defined(__MINGW64_VERSION_MAJOR) && (!defined(_MSC_VER) || _MSC_VER < 1800) #define PRIuMAX "I64u" @@ -580,4 +580,4 @@ int main(int argc, const char **argv); /* * Used by Pthread API implementation for Windows */ -extern int err_win_to_posix(DWORD winerr); +int err_win_to_posix(DWORD winerr); diff --git a/compat/win32/pthread.h b/compat/win32/pthread.h index c6cb8dd219..f1cfe73de9 100644 --- a/compat/win32/pthread.h +++ b/compat/win32/pthread.h @@ -50,7 +50,7 @@ typedef struct { DWORD tid; } pthread_t; -extern int pthread_create(pthread_t *thread, const void *unused, +int pthread_create(pthread_t *thread, const void *unused, void *(*start_routine)(void*), void *arg); /* @@ -59,10 +59,10 @@ extern int pthread_create(pthread_t *thread, const void *unused, */ #define pthread_join(a, b) win32_pthread_join(&(a), (b)) -extern int win32_pthread_join(pthread_t *thread, void **value_ptr); +int win32_pthread_join(pthread_t *thread, void **value_ptr); #define pthread_equal(t1, t2) ((t1).tid == (t2).tid) -extern pthread_t pthread_self(void); +pthread_t pthread_self(void); static inline void NORETURN pthread_exit(void *ret) {
