From: Elijah Newren <newren@xxxxxxxxx> Hi Elijah, [Since this is leaving the topic of rename-detection in favour of leak-plugging, I'm shortening the cc-list a bit.] > So, instead, I'd like to see something like the below > (built on top of my series): Thanks a lot. I now have the below patch in my tree as a preparatory part of a three-patch series on top of your series. Since the gist of this patch is entirely your creation, is it ok if I place your Author: and Signed-off-by: on it? Credit where credit is due. As you noted elsewhere [1], Ben is also working in this area. I'd be perfectly happy to sit on these patches until both of your contributions come through to master. [1] https://public-inbox.org/git/CABPp-BFh=gL6RnbST2bgtynkij1Z5TMgAr1Via5_VyteF5eBMg@xxxxxxxxxxxxxx/ Martin -->8-- Subject: merge-recursive: provide pair of `unpack_trees_{start,finish}()` Rename `git_merge_trees()` to `unpack_trees_start()` and extract the call to `discard_index()` into a new function `unpack_trees_finish()`. As a result, these are called early resp. late in `merge_trees()`, making the resource handling clearer. The next commit will expand on that, teaching `..._finish()` to free more memory. (So rather than moving the TODO-comment, just drop it, since it will be addressed soon enough.) Also call `..._finish()` when `merge_trees()` returns early. --- merge-recursive.c | 29 +++++++++++++++-------------- 1 file changed, 15 insertions(+), 14 deletions(-) diff --git a/merge-recursive.c b/merge-recursive.c index 1de8dc1c53..e64102004a 100644 --- a/merge-recursive.c +++ b/merge-recursive.c @@ -337,10 +337,10 @@ static void init_tree_desc_from_tree(struct tree_desc *desc, struct tree *tree) init_tree_desc(desc, tree->buffer, tree->size); } -static int git_merge_trees(struct merge_options *o, - struct tree *common, - struct tree *head, - struct tree *merge) +static int unpack_trees_start(struct merge_options *o, + struct tree *common, + struct tree *head, + struct tree *merge) { int rc; struct tree_desc t[3]; @@ -378,6 +378,11 @@ static int git_merge_trees(struct merge_options *o, return rc; } +static void unpack_trees_finish(struct merge_options *o) +{ + discard_index(&o->orig_index); +} + struct tree *write_tree_from_memory(struct merge_options *o) { struct tree *result = NULL; @@ -3079,13 +3084,14 @@ int merge_trees(struct merge_options *o, return 1; } - code = git_merge_trees(o, common, head, merge); + code = unpack_trees_start(o, common, head, merge); if (code != 0) { if (show(o, 4) || o->call_depth) err(o, _("merging of trees %s and %s failed"), oid_to_hex(&head->object.oid), oid_to_hex(&merge->object.oid)); + unpack_trees_finish(o); return -1; } @@ -3138,20 +3144,15 @@ int merge_trees(struct merge_options *o, hashmap_free(&o->current_file_dir_set, 1); - if (clean < 0) + if (clean < 0) { + unpack_trees_finish(o); return clean; + } } else clean = 1; - /* Free the extra index left from git_merge_trees() */ - /* - * FIXME: Need to also data allocated by setup_unpack_trees_porcelain() - * tucked away in o->unpack_opts.msgs, but the problem is that only - * half of it refers to dynamically allocated data, while the other - * half points at static strings. - */ - discard_index(&o->orig_index); + unpack_trees_finish(o); if (o->call_depth && !(*result = write_tree_from_memory(o))) return -1; -- 2.17.0
