pack-objects.c - write_pack_file():
...
if (pack_to_stdout) {
sha1close(f, sha1, CSUM_CLOSE);
} else if (nr_written == nr_remaining) {
sha1close(f, sha1, CSUM_FSYNC);
} else {
int fd = sha1close(f, sha1, 0);
fixup_pack_header_footer(fd, sha1, pack_tmp_name,
nr_written, sha1, offset);
close(fd);
}
if (!pack_to_stdout) {
struct stat st;
const char *idx_tmp_name;
char tmpname[PATH_MAX];
idx_tmp_name = write_idx_file(NULL, written_list,
nr_written, sha1);
....
ahh, whoops. any advances on that?
grep write_idx_file *.c */*.c
* git-index-pack requires a pack file in order to re-create the index:
i don't want that
* git-pack-objects appears to have no way of telling it "just gimme
index file please"
* fast-import.c appears not to be what's needed either.
so - any other methods for just getting the index file (exclusively?)
any other commands i've missed? if not, are there any other ways of
getting a pack's index of objects without err... getting the index
file? (i believe the answer to be no, but i'm just making sure) and
on that basis i believe it is safe to ask: any objections to a patch
which adds "--index-only" to builtin/pack-objects.c?
