2013-04-19receive-pack: close sideband fd on early pack errorsLibravatar Jeff King1-1/+4
Since commit a22e6f8 (receive-pack: send pack-processing stderr over sideband, 2012-09-21), receive-pack will start an async sideband thread to copy the stderr from our index-pack or unpack-objects child to the client. We hand the thread's input descriptor to unpack(), which puts it in the "err" member of the "struct child_process". After unpack() returns, we use finish_async() to reap the sideband thread. The thread is only ready to die when it gets EOF on its pipe, which is connected to the err descriptor. So we expect all of the write ends of that pipe to be closed as part of unpack(). Normally, this works fine. After start_command forks, it closes the parent copy of the descriptor. Then once the child exits (whether it was successful or not), that closes the only remaining writer. However, there is one code-path in unpack() that does not handle this. Before we decide which of unpack-objects or index-pack to use, we read the pack header ourselves to see how many objects it contains. If there is an error here, we exit without running either sub-command, the pipe descriptor remains open, and we are in a deadlock, waiting for the sideband thread to die (which is in turn waiting for us to close the pipe). We can fix this by making sure that unpack() always closes the pipe before returning. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2013-04-17cat-file: print tags raw for "cat-file -p"Libravatar Jeff King1-71/+0
When "cat-file -p" prints commits, it shows them in their raw format, since git's format is already human-readable. For tags, however, we print the whole thing raw except for one thing: we convert the timestamp on the tagger line into a human-readable date. This dates all the way back to a0f15fa (Pretty-print tagger dates, 2006-03-01). At that time there was no other way to pretty-print a tag. These days, however, neither of those matters much. The normal way to pretty-print a tag is with "git show", which is much more flexible than "cat-file -p". Commit a0f15fa also built "verify-tag --verbose" (and subsequently "tag -v") around the "cat-file -p" output. However, that behavior was lost in commit 62e09ce (Make git tag a builtin, 2007-07-20), and we went back to printing the raw tag contents. Nobody seems to have noticed the bug since then (and it is arguably a saner behavior anyway, as it shows the actual bytes for which we verified the signature). Let's drop the tagger-date formatting for "cat-file -p". It makes us more consistent with cat-file's commit pretty-printer, and as a bonus, we can drop the hand-rolled tag parsing code in cat-file (which happened to behave inconsistently with the tag pretty-printing code elsewhere). This is a change of output format, so it's possible that some callers could considered this a regression. However, the original behavior was arguably a bug (due to the inconsistency with commits), likely nobody was relying on it (even we do not use it ourselves these days), and anyone relying on the "-p" pretty-printer should be able to expect a change in the output format (i.e., while "cat-file" is plumbing, the output format of "-p" was never guaranteed to be stable).

2013-04-06show-branch: use strbuf instead of static bufferLibravatar Jeff King1-9/+8
When we generate relative names (e.g., "master~20^2"), we format the name into a static buffer, then xstrdup the result to attach it to the commit. Since the first thing we add into the static buffer is the already-computed name of the child commit, the names may get longer and longer as the traversal gets deeper, and we may eventually overflow the fixed-size buffer. Fix this by converting the fixed-size buffer into a dynamic strbuf. The performance implications should be minimal, as we end up allocating a heap copy of the name anyway (and now we can just detach the heap copy from the strbuf).

2013-03-22apply --whitespace=fix: avoid running over the postimage bufferLibravatar Junio C Hamano1-6/+10
Originally update-pre-post-images could assume that any whitespace fixing will make the result only shorter by unexpanding runs of leading SPs into HTs and removing trailing whitespaces at the end of lines. Updating the post-image we read from the patch to match the actual result can be performed in-place under this assumption. These days, however, we have tab-in-indent (aka Python) rule whose result can be longer than the original, and we do need to allocate a larger buffer than the input and replace the result. Fortunately the support for lengthening rewrite was already added when we began supporting "match while ignoring whitespace differences" mode in 86c91f91794c (git apply: option to ignore whitespace differences, 2009-08-04). We only need to correctly count the number of bytes necessary to hold the updated result and tell the function to allocate a new buffer. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2013-03-21drop some obsolete "x = x" compiler warning hacksLibravatar Jeff King1-1/+1
In cases where the setting and access of a variable are protected by the same conditional flag, older versions of gcc would generate a "might be used unitialized" warning. We silence the warning by initializing the variable to itself, a hack that gcc recognizes. Modern versions of gcc are smart enough to get this right, going back to at least version 4.3.5. gcc 4.1 does get it wrong in both cases, but is sufficiently old that we probably don't need to care about it anymore.

2013-03-20index-pack: always zero-initialize object_entry listLibravatar Jeff King1-0/+2
Commit 38a4556 (index-pack: start learning to emulate "verify-pack -v", 2011-06-03) added a "delta_depth" counter to each "struct object_entry". Initially, all object entries have their depth set to 0; in resolve_delta, we then set the depth of each delta to "base + 1". Base entries never have their depth touched, and remain at 0. To ensure that all depths start at 0, that commit changed calls to xmalloc the object_entry list into calls to xcalloc. However, it forgot that we grow the list with xrealloc later. These extra entries are used when we add an object from elsewhere to complete a thin pack. If we add a non-delta object, its depth value will just be uninitialized heap data. This patch fixes it by zero-initializing entries we add to the objects list via the xrealloc.

2013-03-19index-pack: guard nr_resolved_deltas reads by lockLibravatar Thomas Rast1-1/+3
The threaded parts of index-pack increment the number of resolved deltas in nr_resolved_deltas guarded by counter_mutex. However, the per-thread outer loop accessed nr_resolved_deltas without any locks. This is not wrong as such, since it doesn't matter all that much whether we get an outdated value. However, unless someone proves that this one lock makes all the performance difference, it would be much cleaner to guard _all_ accesses to the variable with the lock. The only such use is display_progress() in the threaded section (all others are in the conclude_pack() callchain outside the threaded part). To make it obvious that it cannot deadlock, move it out of work_mutex.

deepest_delta is a global variable but is updated without protection in resolve_delta(), a multithreaded function. Add a new mutex for it, but only protect and update when it's actually used (i.e. show_stat is non-zero). Another variable that will not be updated is delta_depth in "struct object_entry" as it's only useful when show_stat is 1. Putting it in "if (show_stat)" makes it clearer.

2013-03-02mailsplit: sort maildir filenames more cleverlyLibravatar Jeff King1-0/+23
A maildir does not technically record the order in which items were placed into it. That means that when applying a patch series from a maildir, we may get the patches in the wrong order. We try to work around this by sorting the filenames. Unfortunately, this may or may not work depending on the naming scheme used by the writer of the maildir. For instance, mutt will write: ${epoch_seconds}.${pid}_${seq}.${host} where we have: - epoch_seconds: timestamp at which entry was written - pid: PID of writing process - seq: a sequence number to ensure uniqueness of filenames - host: hostname None of the numbers are zero-padded. Therefore, when we sort the names as byte strings, entries that cross a digit boundary (e.g., 10) will sort out of order. In the case of timestamps, it almost never matters (because we do not cross a digit boundary in the epoch time very often these days). But for the sequence number, a 10-patch series would be ordered as 1, 10, 2, 3, etc. To fix this, we can use a custom sort comparison function which traverses each string, comparing chunks of digits numerically, and otherwise doing a byte-for-byte comparison. That would sort: 123.456_1.bar 123.456_2.bar ... 123.456_10.bar according to the sequence number. Since maildir does not define a filename format, this is really just a heuristic. But it happens to work for mutt, and there is a reasonable chance that it will work for other writers, too (at least as well as a straight sort).
