It seems that the result of calling init_revisions() from backfill is leaked? https://github.com/git/git/actions/runs/12218430154/job/34083929479 I did not dig further but the below is from my local leaksanitizer run. Thanks. ================================================================= ==git==182342==ERROR: LeakSanitizer: detected memory leaks Direct leak of 576 byte(s) in 1 object(s) allocated from: #0 0x55d4b0e42915 in __interceptor_realloc (git+0x84915) (BuildId: c861e65ec43b0a3ef46b9555a81d6ddfc2358e8e) #1 0x55d4b119ce6d in xrealloc wrapper.c:140:8 #2 0x55d4b11204d4 in add_rev_cmdline revision.c:1563:2 #3 0x55d4b11187a1 in handle_revision_arg_1 revision.c:2263:2 #4 0x55d4b1118398 in handle_revision_arg revision.c:2275:12 #5 0x55d4b0e5233b in do_backfill builtin/backfill.c:100:2 #6 0x55d4b0e52253 in cmd_backfill builtin/backfill.c:146:9 #7 0x55d4b0e46b80 in run_builtin git.c:480:11 #8 0x55d4b0e45502 in handle_builtin git.c:741:9 #9 0x55d4b0e4649c in run_argv git.c:808:4 #10 0x55d4b0e45274 in cmd_main git.c:948:19 #11 0x55d4b0f6da8a in main common-main.c:9:11 #12 0x7ff25f97ac89 in __libc_start_call_main csu/../sysdeps/nptl/libc_start_call_main.h:58:16 #13 0x7ff25f97ad44 in __libc_start_main csu/../csu/libc-start.c:360:3 #14 0x55d4b0e171e0 in _start (git+0x591e0) (BuildId: c861e65ec43b0a3ef46b9555a81d6ddfc2358e8e) DEDUP_TOKEN: __interceptor_realloc--xrealloc--add_rev_cmdline--handle_revision_arg_1--handle_revision_arg--do_backfill--cmd_backfill--run_builtin--handle_builtin--run_argv--cmd_main--main--__libc_start_call_main--__libc_start_main--_start Indirect leak of 5 byte(s) in 1 object(s) allocated from: #0 0x55d4b0e424b6 in __interceptor_malloc (git+0x844b6) (BuildId: c861e65ec43b0a3ef46b9555a81d6ddfc2358e8e) #1 0x7ff25f9f34f9 in strdup string/strdup.c:42:15 #2 0x55d4b119cb14 in xstrdup wrapper.c:43:14 #3 0x55d4b1120506 in add_rev_cmdline revision.c:1565:23 #4 0x55d4b11187a1 in handle_revision_arg_1 revision.c:2263:2 #5 0x55d4b1118398 in handle_revision_arg revision.c:2275:12 #6 0x55d4b0e5233b in do_backfill builtin/backfill.c:100:2 #7 0x55d4b0e52253 in cmd_backfill builtin/backfill.c:146:9 #8 0x55d4b0e46b80 in run_builtin git.c:480:11 #9 0x55d4b0e45502 in handle_builtin git.c:741:9 #10 0x55d4b0e4649c in run_argv git.c:808:4 #11 0x55d4b0e45274 in cmd_main git.c:948:19 #12 0x55d4b0f6da8a in main common-main.c:9:11 #13 0x7ff25f97ac89 in __libc_start_call_main csu/../sysdeps/nptl/libc_start_call_main.h:58:16 #14 0x7ff25f97ad44 in __libc_start_main csu/../csu/libc-start.c:360:3 #15 0x55d4b0e171e0 in _start (git+0x591e0) (BuildId: c861e65ec43b0a3ef46b9555a81d6ddfc2358e8e) DEDUP_TOKEN: __interceptor_malloc--strdup--xstrdup--add_rev_cmdline--handle_revision_arg_1--handle_revision_arg--do_backfill--cmd_backfill--run_builtin--handle_builtin--run_argv--cmd_main--main--__libc_start_call_main--__libc_start_main--_start SUMMARY: LeakSanitizer: 581 byte(s) leaked in 2 allocation(s).
