From 886a6677a847a5b7fdc1e44240f90cc81d91b9ad Mon Sep 17 00:00:00 2001 From: Anatol Pomozov Date: Wed, 29 Jan 2020 21:27:10 -0800 Subject: Eliminate extra loop over dbs_sync Current flow looks like loop dbs_sync { loop pkgs { if pkg.db == db then process(pkg, db) } } Package sync transaction always has a counterpart in the dbs_sync list (I cannot come up with a use-case when it is not true). So the loop can be simplified to: loop pkgs { process(pkg, pkg.db) } Tested: 'ninja test' & manually by using pacman with this patch for a week Signed-off-by: Anatol Pomozov Signed-off-by: Allan McRae --- lib/libalpm/sync.c | 14 +++++--------- 1 file changed, 5 insertions(+), 9 deletions(-) diff --git a/lib/libalpm/sync.c b/lib/libalpm/sync.c index d02a435f..4d93f41f 100644 --- a/lib/libalpm/sync.c +++ b/lib/libalpm/sync.c @@ -705,16 +705,14 @@ static struct dload_payload *build_payload(alpm_handle_t *handle, return payload; } -static int find_dl_candidates(alpm_db_t *repo, alpm_list_t **files) +static int find_dl_candidates(alpm_handle_t *handle, alpm_list_t **files) { - alpm_list_t *i; - alpm_handle_t *handle = repo->handle; - - for(i = handle->trans->add; i; i = i->next) { + for(alpm_list_t *i = handle->trans->add; i; i = i->next) { alpm_pkg_t *spkg = i->data; - if(spkg->origin != ALPM_PKG_FROM_FILE && repo == spkg->origin_data.db) { + if(spkg->origin != ALPM_PKG_FROM_FILE) { char *fpath = NULL; + alpm_db_t *repo = spkg->origin_data.db; if(!repo->servers) { handle->pm_errno = ALPM_ERR_SERVER_NONE; @@ -802,9 +800,7 @@ static int download_files(alpm_handle_t *handle) handle->totaldlcb(total_size); } - for(i = handle->dbs_sync; i; i = i->next) { - errors += find_dl_candidates(i->data, &files); - } + errors += find_dl_candidates(handle, &files); if(files) { /* check for necessary disk space for download */ -- cgit v1.2.3-70-g09d2
