From aaa5f26d6ed4a00b75b8f2a7bd27fcb3cca54e08 Mon Sep 17 00:00:00 2001 From: Jouke Witteveen Date: Fri, 10 Jun 2016 18:13:02 +0200 Subject: [PATCH] libalpm: ignore .hook suffix when sorting hooks It is desirable to have 'a-post.hook' ordered after 'a.hook'. For this, it is needed to ignore the suffix when sorting. --- lib/libalpm/hook.c | 16 ++++++++++++---- lib/libalpm/hook.h | 2 ++ 2 files changed, 14 insertions(+), 4 deletions(-) diff --git a/lib/libalpm/hook.c b/lib/libalpm/hook.c index 6890a6e..a00d414 100644 --- a/lib/libalpm/hook.c +++ b/lib/libalpm/hook.c @@ -535,7 +535,16 @@ static int _alpm_hook_triggered(alpm_handle_t *handle, struct _alpm_hook_t *hook static int _alpm_hook_cmp(struct _alpm_hook_t *h1, struct _alpm_hook_t *h2) { - return strcmp(h1->name, h2->name); + size_t suflen = strlen(ALPM_HOOK_SUFFIX), l1, l2; + int ret; + l1 = strlen(h1->name) - suflen; + l2 = strlen(h2->name) - suflen; + /* exclude the suffixes from comparison */ + ret = strncmp(h1->name, h2->name, l1 <= l2 ? l1 : l2); + if(ret == 0 && l1 != l2) { + return l1 < l2 ? -1 : 1; + } + return ret; } static alpm_list_t *find_hook(alpm_list_t *haystack, const void *needle) @@ -618,8 +627,7 @@ int _alpm_hook_run(alpm_handle_t *handle, alpm_hook_when_t when) alpm_event_hook_t event = { .when = when }; alpm_event_hook_run_t hook_event; alpm_list_t *i, *hooks = NULL, *hooks_triggered = NULL; - const char *suffix = ".hook"; - size_t suflen = strlen(suffix), triggered = 0; + size_t suflen = strlen(ALPM_HOOK_SUFFIX), triggered = 0; int ret = 0; for(i = alpm_list_last(handle->hookdirs); i; i = alpm_list_previous(i)) { @@ -666,7 +674,7 @@ int _alpm_hook_run(alpm_handle_t *handle, alpm_hook_when_t when) memcpy(path + dirlen, entry.d_name, name_len + 1); if(name_len < suflen - || strcmp(entry.d_name + name_len - suflen, suffix) != 0) { + || strcmp(entry.d_name + name_len - suflen, ALPM_HOOK_SUFFIX) != 0) { _alpm_log(handle, ALPM_LOG_DEBUG, "skipping non-hook file %s\n", path); continue; } diff --git a/lib/libalpm/hook.h b/lib/libalpm/hook.h index 01eb3ed..8cc97f0 100644 --- a/lib/libalpm/hook.h +++ b/lib/libalpm/hook.h @@ -22,6 +22,8 @@ #include "alpm.h" +#define ALPM_HOOK_SUFFIX ".hook" + int _alpm_hook_run(alpm_handle_t *handle, alpm_hook_when_t when); #endif /* _ALPM_HOOK_H */ -- 2.8.3
