| * diff.c: rearrange xcalloc argumentsBrian Gesiak2014-05-27
| | | | | | | | | | | | | | | | | | | | | | | | xcalloc() takes two arguments: the number of elements and their size. diffstat_add() passes the arguments in reverse order, passing the size of a diffstat_file*, followed by the number of diffstat_file* to be allocated. Rearrange them so they are in the correct order. Signed-off-by: Brian Gesiak <modocache@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

|\ \ | |/ |/| | | | | | | | | | | | | "git format-patch" did not enforce the rule that the "--follow" option from the log/diff family of commands must be used with exactly one pathspec. * jk/diff-follow-must-take-one-pathspec: move "--follow needs one pathspec" rule to diff_setup_done
| * move "--follow needs one pathspec" rule to diff_setup_doneJeff King2014-05-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Because of the way "--follow" is implemented, we must have exactly one pathspec. "git log" enforces this restriction, but other users of the revision traversal code do not. For example, "git format-patch --follow" will segfault during try_to_follow_renames, as we have no pathspecs at all. We can push this check down into diff_setup_done, which is probably a better place anyway. It is the diff code that introduces this restriction, so other parts of the code should not need to care themselves. Reported-by: "Michael S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We currently generate the command-line for the external command using a fixed-length array of size 10. But if there is a rename, we actually need 11 elements (10 items, plus a NULL), and end up writing a random NULL onto the stack. Rather than bump the limit, let's just use an argv_array, which makes this sort of error impossible.

The actual content test is performed too late in the process and the shortcut may be taken prematurely, leading to incorrect return code. Assume we do "git diff --quiet". If we have a stat-dirty file "a" and a really dirty file "b". We break the loop in run_diff_files() and stop after "a" because we have got a "change". Later in diffcore_skip_stat_unmatch() we find out "a" is actually not changed. But there's nothing else in the diff queue, we incorrectly declare "no change", ignoring the fact that "b" is changed. This also happens to "git diff --quiet HEAD" when it hits diff_can_quit_early() in oneway_diff(). This patch does the content test earlier in order to keep going if "a" is unchanged. The test result is cached so that when diffcore_skip_stat_unmatch() is done in the end, we spend no cycles on re-testing "a".

* | | | diff: remove ternary operator evaluating always to trueStefan Beller2013-08-09
| |_|/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The line being changed is deep inside the function builtin_diff. The variable name_b, which is used to evaluate the ternary expression must evaluate to true at that position, hence the replacement with just name_b. The name_b variable only occurs a few times in that lengthy function: As a parameter to the function itself: static void builtin_diff(const char *name_a, const char *name_b, ... The next occurrences are at: /* Never use a non-valid filename anywhere if at all possible */ name_a = DIFF_FILE_VALID(one) ? name_a : name_b; name_b = DIFF_FILE_VALID(two) ? name_b : name_a; a_one = quote_two(a_prefix, name_a + (*name_a == '/')); b_two = quote_two(b_prefix, name_b + (*name_b == '/')); In the last line of this block 'name_b' is dereferenced and compared to '/'. This would crash if name_b was NULL. Hence in the following code we can assume name_b being non-null. The next occurrence is just as a function argument, which doesn't change the memory, which name_b points to, so the assumption name_b being not null still holds: emit_rewrite_diff(name_a, name_b, one, two, textconv_one, textconv_two, o); The next occurrence would be the line of this patch. As name_b still must be not null, we can remove the ternary operator. Inside the emit_rewrite_diff function there is a also a line ecbdata.ws_rule = whitespace_rule(name_b ? name_b : name_a); which was also simplified as there is also a dereference before the ternary operator.

The question I have is what do we do if we really need to keep track of on-disk changes in the index. The result is - diff-lib.c: setting CE_UPTODATE - name-hash.c: setting CE_HASHED - preload-index.c, read-cache.c, unpack-trees.c and builtin/update-index: obvious - entry.c: write_entry() may refresh the checked out entry via fill_stat_cache_info(). This causes "non-const struct cache_entry *" in builtin/apply.c, builtin/checkout-index.c and builtin/checkout.c - builtin/ls-files.c: --with-tree changes stagemask and may set CE_UPDATE Of these, write_entry() and its call sites are probably most interesting because it modifies on-disk info. But this is stat info and can be retrieved via refresh, at least for porcelain commands. Other just uses ce_flags for local purposes. So, keeping track of "dirty" entries is just a matter of setting a flag in index modification functions exposed by read-cache.c. Except unpack-trees, the rest of the code base does not do anything funny behind read-cache's back. The actual patch is less valueable than the summary above. But if anyone wants to re-identify the above sites. Applying this patch, then this: diff --git a/cache.h b/cache.h index 430d021..1692891 100644 --- a/cache.h +++ b/cache.h @@ -267,7 +267,7 @@ static inline unsigned int canon_mode(unsigned int mode) #define cache_entry_size(len) (offsetof(struct cache_entry,name) + (len) + 1) struct index_state { - struct cache_entry **cache; + const struct cache_entry **cache; unsigned int version; unsigned int cache_nr, cache_alloc, cache_changed; struct string_list *resolve_undo; will help quickly identify them without bogus warnings.
