* checkout: fix memory leakjs/plug-leaksJunio C Hamano2017-05-091-0/+1
| | | | | | | | | When "git checkout -m" does an in-core three-way merge to carry local modifications forward to check out a different branch, the code forgot to free the updated contents it has in-core. Noticed-by: René Scharfe <l.s.r@web.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>

* name-rev: avoid leaking memory in the `deref` caseJohannes Schindelin2017-05-081-2/+5
| | | | | | | | | | | | When the `name_rev()` function is asked to dereference the tip name, it allocates memory. But when it turns out that another tip already described the commit better than the current one, we forgot to release the memory. Pointed out by Coverity.

* remote: plug memory leak in match_explicit()Johannes Schindelin2017-05-081-2/+3
| | | | | | | | | | | The `guess_ref()` returns an allocated buffer of which `make_linked_ref()` does not take custody (`alloc_ref()` makes a copy), therefore we need to release the buffer afterwards.

* add_reflog_for_walk: avoid memory leakJohannes Schindelin2017-05-081-3/+17
| | | | | | | | | | | | | | We free()d the `log` buffer when dwim_log() returned 1, but not when it returned a larger value (which meant that it still allocated the buffer but we simply ignored it). While in the vicinity, make sure that the `reflogs` structure as well as the `branch` variable are released properly, too. Identified by Coverity.

* split_commit_in_progress(): simplify & fix memory leakJohannes Schindelin2017-05-081-14/+14
| | | | | | | | | | | | | | This function did a whole lot of unnecessary work, such as reading in four files just to figure out that, oh, hey, we do not need to look at them after all because the HEAD is not detached. Simplify the entire function to return early when possible, to read in the files only when necessary, and to release the allocated memory always (there was a leak, reported via Coverity, where we failed to release the allocated strings if the HEAD is not detached).

* mailinfo & mailsplit: check for EOF while parsingJohannes Schindelin2017-05-082-1/+18
| | | | | | | | | | | | | | | While POSIX states that it is okay to pass EOF to isspace() (and it seems to be implied that EOF should *not* be treated as whitespace), and also to pass EOF to ungetc() (which seems to be intended to fail without buffering the character), it is much better to handle these cases explicitly. Not only does it reduce head-scratching (and helps static analysis avoid reporting false positives), it also lets us handle files containing nothing but whitespace by erroring out.

| | | | | | | | | | | | When we could not convert the UTF-8 sequence into Unicode for writing to the Console, we should not try to write an insanely-long sequence of invalid wide characters (mistaking the negative return value for an unsigned length).

* winansi: avoid use of uninitialized valueJohannes Schindelin2017-05-081-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | To initialize the foreground color attributes of "plain text", our ANSI emulation tries to infer them from the currently attached console while running the is_console() function. This function first tries to detect any console attached to stdout, then it is called with stderr. If neither stdout nor stderr has any console attached, it does not actually matter what we use for "plain text" attributes, as we never need to output any text to any console in that case. However, after working on stdout and stderr, is_console() is called with stdin, and it still tries to initialize the "plain text" attributes if they had not been initialized earlier. In this case, we cannot detect any attributes, and we used an uninitialized value for them. Naturally, Coverity complained about this use case because it could not reason about the code deeply enough to figure out that we do not even use those attributes in that case. Let's just initialize the value to 0 in that case, both to avoid future Coverity reports, and to help catch future regressions in case anybody changes the order of the is_console() calls (which would make the text black on black).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the scripted version of the interactive rebase, there was no internal representation of the todo list; it was re-read before every command. That allowed the hack that an `exec` command could append (or even completely rewrite) the todo list. This hack was broken by the partial conversion of the interactive rebase to C, and this patch reinstates it. We also add a small test to verify that this fix does not regress in the future.

We can quit when the two indices are equal, since: 1. Swapping an element with itself is a noop. 2. If i and j are equal, then in the next iteration i is guaranteed to be bigge than j, and we will exit the loop. So exiting the loop on equality is slightly more efficient. And more importantly, the new SWAP() macro does not expect to handle noop swaps; it will call memcpy() with the same src and dst pointers in this case. It's unclear whether that causes a problem on any platforms by violating the "overlapping memory" constraint of memcpy, but it does cause valgrind to complain.

Depending on your workflow and project, this can be either convenient or annoying. For instance, my clone of gitster.git contains 74 local "jk/*" branches, but origin contains another 147. When I want to checkout a local branch but can't quite remember the name, tab completion shows me 251 entries. And worse, for a topic that has been picked up for pu, the upstream branch name is likely to be similar to mine, leading to a high probability that I pick the wrong one and accidentally create a new branch. This patch adds a way for the user to tell the completion code not to include DWIM suggestions for checkout. This can already be done by typing: git checkout --no-guess jk/<TAB> but that's rather cumbersome. The downside, of course, is that you no longer get completion support when you _do_ want to invoke the DWIM behavior. But depending on your workflow, that may not be a big loss (for instance, in git.git I am much more likely to want to detach, so I'd type "git checkout origin/jk/<TAB>" anyway).

Note that an internal consistency check that was previously done in `write_packed_entry_fn()` is not there anymore. This is actually an improvement: The old error message was emitted when there is an entry in the packed-ref cache that is not `REF_KNOWS_PEELED`, and when we attempted to peel the reference, the result was `PEEL_INVALID`, `PEEL_IS_SYMREF`, or `PEEL_BROKEN`. Since a packed ref cannot be a symref, `PEEL_IS_SYMREF` and `PEEL_BROKEN` can be ruled out. So we're left with `PEEL_INVALID`. An entry without `REF_KNOWS_PEELED` can get into the packed-refs cache in the following two ways: * The reference was read from a `packed-refs` file that didn't have the `fully-peeled` attribute. In that case, we *don't want* to emit an error, because the broken value is presumably a stale value of the reference that is now masked by a loose version of the same reference (which we just don't happen to be packing this time). This is a perfectly legitimate situation and doesn't indicate that the repository is corrupt. The old code incorrectly emits an error message in this case. (It was probably never reported as a bug because this scenario is rare.) * The reference was a loose reference that was just added to the packed ref cache by `files_packed_refs()` via `pack_if_possible_fn()` in preparation for being packed. The latter function refuses to pack a reference for which `entry_resolves_to_object()` returns false, and otherwise calls `peel_entry()` itself and checks the return value. So an entry added this way should always have `REF_KNOWS_PEELED` and shouldn't trigger the error message in either the old code or the new.

The new functionality makes it possible for `files_ref_iterator_begin()` to be made more ignorant of the internals of `ref_cache`, and `find_containing_dir()` and `prime_ref_dir()` to be made private.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Extract a new function, `get_loose_ref_cache()`, from get_loose_ref_dir().
