Have the REV_INFO_INIT macro added in [1] declare more members of "struct rev_info" that we can initialize statically, and have repo_init_revisions() do so with the memcpy(..., &blank) idiom introduced in [2]. As the comment for the "REV_INFO_INIT" macro notes this still isn't sufficient to initialize a "struct rev_info" for use yet. But we are getting closer to that eventual goal. Even though we can't fully initialize a "struct rev_info" with REV_INFO_INIT it's useful for readability to clearly separate those things that we can statically initialize, and those that we can't. This change could replace the: list_objects_filter_init(&revs->filter); In the repo_init_revisions() with this line, at the end of the REV_INFO_INIT deceleration in revisions.h: .filter = LIST_OBJECTS_FILTER_INIT, \ But doing so would produce a minor conflict with an outstanding topic[3]. Let's skip that for now. I have follow-ups to initialize more of this statically, e.g. changes to get rid of grep_init(). We can initialize more members with the macro in a future series. 1. f196c1e908d (revisions API users: use release_revisions() needing REV_INFO_INIT, 2022-04-13) 2. 5726a6b4012 (*.c *_init(): define in terms of corresponding *_INIT macro, 2021-07-01) 3. https://lore.kernel.org/git/265b292ed5c2de19b7118dfe046d3d9d932e2e89.1667901510.git.ps@xxxxxx/ Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@xxxxxxxxx> --- A small follow-up to what I mentioned in[1]. As noted above there's a very small part of Patrick's series that *could* use this[2] (getting rid of the trivial "init_ref_exclusions"), but let's not hold that up for this minor cleanup, and have these proceed concurrently without conflicts. 1. https://lore.kernel.org/git/221107.86tu3ax5b6.gmgdl@xxxxxxxxxxxxxxxxxxx/ 2. https://lore.kernel.org/git/265b292ed5c2de19b7118dfe046d3d9d932e2e89.1667901510.git.ps@xxxxxx/ revision.c | 19 ++----------------- revision.h | 18 +++++++++++++++++- 2 files changed, 19 insertions(+), 18 deletions(-) diff --git a/revision.c b/revision.c index 0760e78936e..c6b39965834 100644 --- a/revision.c +++ b/revision.c @@ -1865,30 +1865,15 @@ void repo_init_revisions(struct repository *r, struct rev_info *revs, const char *prefix) { - memset(revs, 0, sizeof(*revs)); + struct rev_info blank = REV_INFO_INIT; + memcpy(revs, &blank, sizeof(*revs)); revs->repo = r; - revs->abbrev = DEFAULT_ABBREV; - revs->simplify_history = 1; revs->pruning.repo = r; - revs->pruning.flags.recursive = 1; - revs->pruning.flags.quick = 1; revs->pruning.add_remove = file_add_remove; revs->pruning.change = file_change; revs->pruning.change_fn_data = revs; - revs->sort_order = REV_SORT_IN_GRAPH_ORDER; - revs->dense = 1; revs->prefix = prefix; - revs->max_age = -1; - revs->max_age_as_filter = -1; - revs->min_age = -1; - revs->skip_count = -1; - revs->max_count = -1; - revs->max_parents = -1; - revs->expand_tabs_in_log = -1; - - revs->commit_format = CMIT_FMT_DEFAULT; - revs->expand_tabs_in_log_default = 8; grep_init(&revs->grep_filter, revs->repo); revs->grep_filter.status_only = 1; diff --git a/revision.h b/revision.h index afe1b77985f..8493a3f3b93 100644 --- a/revision.h +++ b/revision.h @@ -357,7 +357,23 @@ struct rev_info { * called before release_revisions() the "struct rev_info" can be left * uninitialized. */ -#define REV_INFO_INIT { 0 } +#define REV_INFO_INIT { \ + .abbrev = DEFAULT_ABBREV, \ + .simplify_history = 1, \ + .pruning.flags.recursive = 1, \ + .pruning.flags.quick = 1, \ + .sort_order = REV_SORT_IN_GRAPH_ORDER, \ + .dense = 1, \ + .max_age = -1, \ + .max_age_as_filter = -1, \ + .min_age = -1, \ + .skip_count = -1, \ + .max_count = -1, \ + .max_parents = -1, \ + .expand_tabs_in_log = -1, \ + .commit_format = CMIT_FMT_DEFAULT, \ + .expand_tabs_in_log_default = 8, \ +} /** * Initialize a rev_info structure with default values.
