From 068eac91ce04b9aca163acb1927c3878c45d1a07 Mon Sep 17 00:00:00 2001 From: Yasushi SHOJI Date: Sat, 13 Aug 2005 19:58:56 +0900 Subject: [PATCH] [PATCH] plug memory leak in diff.c::diff_free_filepair() When I run git-diff-tree on big change, it seems the command eats so much memory. so I just put git under valgrind to see what's going on. diff_free_filespec_data() doesn't free diff_filespec itself. [jc: I ended up doing things slightly differently from Yasushi's patch. The original idea was to use free_filespec_data() only to free the data portion and keep useing the filespec itself, but no existing code seems to do things that way, so I just yanked that part out.] Signed-off-by: Yasushi SHOJI Signed-off-by: Junio C Hamano --- diff.c | 9 ++++----- diffcore-break.c | 4 ++-- diffcore.h | 2 +- 3 files changed, 7 insertions(+), 8 deletions(-) diff --git a/diff.c b/diff.c index 3e52fec187..bb2a43b5b0 100644 --- a/diff.c +++ b/diff.c @@ -405,14 +405,13 @@ int diff_populate_filespec(struct diff_filespec *s, int size_only) return 0; } -void diff_free_filespec_data(struct diff_filespec *s) +void diff_free_filespec(struct diff_filespec *s) { if (s->should_free) free(s->data); else if (s->should_munmap) munmap(s->data, s->size); - s->should_free = s->should_munmap = 0; - s->data = NULL; + free(s); } static void prep_temp_blob(struct diff_tempfile *temp, @@ -769,8 +768,8 @@ struct diff_filepair *diff_queue(struct diff_queue_struct *queue, void diff_free_filepair(struct diff_filepair *p) { - diff_free_filespec_data(p->one); - diff_free_filespec_data(p->two); + diff_free_filespec(p->one); + diff_free_filespec(p->two); free(p); } diff --git a/diffcore-break.c b/diffcore-break.c index 06f9a7f0ee..b0c8461e12 100644 --- a/diffcore-break.c +++ b/diffcore-break.c @@ -231,8 +231,8 @@ static void merge_broken(struct diff_filepair *p, dp = diff_queue(outq, d->one, c->two); dp->score = p->score; - diff_free_filespec_data(d->two); - diff_free_filespec_data(c->one); + diff_free_filespec(d->two); + diff_free_filespec(c->one); free(d); free(c); } diff --git a/diffcore.h b/diffcore.h index f1b5ca748c..633d1ae5cf 100644 --- a/diffcore.h +++ b/diffcore.h @@ -43,7 +43,7 @@ extern void fill_filespec(struct diff_filespec *, const unsigned char *, unsigned short); extern int diff_populate_filespec(struct diff_filespec *, int); -extern void diff_free_filespec_data(struct diff_filespec *); +extern void diff_free_filespec(struct diff_filespec *); struct diff_filepair { struct diff_filespec *one; -- 2.11.4.GIT
