Before the grep_source interface existed, grep_buffer was used by two types of callers: 1. Ones which pulled a file into a buffer, and then wanted to supply the file's name for the output (i.e., git grep). 2. Ones which really just wanted to grep a buffer (i.e., git log --grep). Callers in set (1) should now be using grep_source. Callers in set (2) always pass NULL for the "name" parameter of grep_buffer. We can therefore get rid of this now-useless parameter.

The grep_source interface (as opposed to grep_buffer) will eventually gives us a richer interface for telling the low-level grep code about our buffers. Eventually this will lead to things like better binary-file handling. For now, it lets us drop a lot of now-redundant code. The conversion is mostly straight-forward. One thing to note is that the memory ownership rules for "struct grep_source" are different than the "struct work_item" found here (the former will copy things like the filename, rather than taking ownership). Therefore you will also see some slight tweaking of when filename buffers are released. Signed-off-by: NJeff King <peff@peff.net> Signed-off-by: NJunio C Hamano <gitster@pobox.com>

The main interface to the low-level grep code is grep_buffer, which takes a pointer to a buffer and a size. This is convenient and flexible (we use it to grep commit bodies, files on disk, and blobs by sha1), but it makes it hard to pass extra information about what we are grepping (either for correctness, like overriding binary auto-detection, or for optimizations, like lazily loading blob contents). Instead, let's encapsulate the idea of a "grep source", including the buffer, its size, and where the data is coming from. This is similar to the diff_filespec structure used by the diff code (unsurprising, since future patches will implement some of the same optimizations found there). The diffstat is slightly scarier than the actual patch content. Most of the modified lines are simply replacing access to raw variables with their counterparts that are now in a "struct grep_source". Most of the added lines were taken from builtin/grep.c, which partially abstracted the idea of grep sources (for file vs sha1 sources). Instead of dropping the now-redundant code, this patch leaves builtin/grep.c using the traditional grep_buffer interface (which now wraps the grep_source interface). That makes it easy to test that there is no change of behavior (yet). Signed-off-by: NJeff King <peff@peff.net> Signed-off-by: NJunio C Hamano <gitster@pobox.com>

The multi-threaded git-grep code needs to serialize access to the thread-unsafe read_sha1_file call. It does this with a mutex that is local to builtin/grep.c. Let's instead push this down into grep.c, where it can be used by both builtin/grep.c and grep.c. This will let us safely teach the low-level grep.c code tricks that involve reading from the object db. Signed-off-by: NJeff King <peff@peff.net> Signed-off-by: NJunio C Hamano <gitster@pobox.com>

The low-level grep code traditionally didn't care about threading, as it doesn't do any threading itself and didn't call out to other non-thread-safe code. That changed with 0579f91d (grep: enable threading with -p and -W using lazy attribute lookup, 2011-12-12), which pushed the lookup of funcname attributes (which is not thread-safe) into the low-level grep code. As a result, the low-level code learned about a new global "grep_attr_mutex" to serialize access to the attribute code. A multi-threaded caller (e.g., builtin/grep.c) is expected to initialize the mutex and set "use_threads" in the grep_opt structure. The low-level code only uses the lock if use_threads is set. However, putting the use_threads flag into the grep_opt struct is not the most logical place. Whether threading is in use is not something that matters for each call to grep_buffer, but is instead global to the whole program (i.e., if any thread is doing multi-threaded grep, every other thread, even if it thinks it is doing its own single-threaded grep, would need to use the locking). In practice, this distinction isn't a problem for us, because the only user of multi-threaded grep is "git-grep", which does nothing except call grep. This patch turns the opt->use_threads flag into a global flag. More important than the nit-picking semantic argument above is that this means that the locking functions don't need to actually have access to a grep_opt to know whether to lock. Which in turn can make adding new locks simpler, as we don't need to pass around a grep_opt. Signed-off-by: NJeff King <peff@peff.net> Signed-off-by: NJunio C Hamano <gitster@pobox.com>

zsh adds a backslash (foo\ ) for each item in the COMPREPLY array if IFS doesn't contain spaces. This issue has been reported[1], but there is no solution yet. This wasn't a problem due to another bug[2], which was fixed in zsh version 4.3.12. After this change, 'git checkout ma<tab>' would resolve to 'git checkout master\ '. Aditionally, the introduction of __gitcomp_nl in commit a31e6262 (completion: optimize refs completion) in git also made the problem apparent, as Matthieu Moy reported. The simplest and most generic solution is to hide all the changes we do to IFS, so that "foo \nbar " is recognized by zsh as "foo bar". This works on versions of git before and after the introduction of __gitcomp_nl (a31e6262), and versions of zsh before and after 4.3.12. Once zsh is fixed, we should conditionally disable this workaround to have the same benefits as bash users.

The pathspec structure has a few bits of data to drive various operation modes after we unified the pathspec matching logic in various codepaths. For example, max_depth field is there so that "git grep" can limit the output for files found in limited depth of tree traversal. Also in order to show just the surface level differences in "git diff-tree", recursive field stops us from descending into deeper level of the tree structure when it is set to false, and this also affects pathspec matching when we have wildcards in the pathspec. The diff-index has always wanted the recursive behaviour, and wanted to match pathspecs without any depth limit. But we forgot to do so when we updated tree_entry_interesting() logic to unify the pathspec matching logic.

The credential-cache helper will try to connect to its daemon over a unix socket. Originally, a failure to do so was silently ignored, and we would either give up (if performing a "get" or "erase" operation), or spawn a new daemon (for a "store" operation). But since 8ec6c8d7, we try to report more errors. We detect a missing daemon by checking for ENOENT on our connection attempt. If the daemon is missing, we continue as before (giving up or spawning a new daemon). For any other error, we die and report the problem. However, checking for ENOENT is not sufficient for a missing daemon. We might also get ECONNREFUSED if a dead daemon process left a stale socket. This generally shouldn't happen, as the daemon cleans up after itself, but the daemon may not always be given a chance to do so (e.g., power loss, "kill -9"). The resulting state is annoying not just because the helper outputs an extra useless message, but because it actually blocks the helper from spawning a new daemon to replace the stale socket. Fix it by checking for ECONNREFUSED. Signed-off-by: NJeff King <peff@peff.net> Signed-off-by: NJunio C Hamano <gitster@pobox.com>

Two "^" characters were incorrectly being interpreted as markup for superscripting. Fix them by writing them as attribute references "{caret}". Although a single "^" character in a paragraph cannot be misinterpreted in this way, also write other "^" characters as "{caret}" in the interest of good hygiene (unless they are in literal paragraphs, of course, in which context attribute references are not recognized). Spell "{}" consistently, namely *not* quoted as "\{\}". Since the braces are empty, they cannot be interpreted as an attribute reference, and either spelling is OK. So arbitrarily choose one variation and use it consistently. Signed-off-by: NMichael Haggerty <mhagger@alum.mit.edu> Signed-off-by: NJunio C Hamano <gitster@pobox.com>

When creating a pack using objects that reside in existing packs, we try to avoid recomputing futile delta between an object (trg) and a candidate for its base object (src) if they are stored in the same packfile, and trg is not recorded as a delta already. This heuristics makes sense because it is likely that we tried to express trg as a delta based on src but it did not produce a good delta when we created the existing pack. As the pack heuristics prefer producing delta to remove data, and Linus's law dictates that the size of a file grows over time, we tend to record the newest version of the file as inflated, and older ones as delta against it. When creating a thin-pack to transfer recent history, it is likely that we will try to send an object that is recorded in full, as it is newer. But the heuristics to avoid recomputing futile delta effectively forbids us from attempting to express such an object as a delta based on another object. Sending an object in full is often more expensive than sending a suboptimal delta based on other objects, and it is even more so if we could use an object we know the receiving end already has (i.e. preferred base object) as the delta base. Tweak the recomputation avoidance logic, so that we do not punt on computing delta against a preferred base object. The effect of this change can be seen on two simulated upload-pack workloads. The first is based on 44 reflog entries from my git.git origin/master reflog, and represents the packs that kernel.org sent me git updates for the past month or two. The second workload represents much larger fetches, going from git's v1.0.0 tag to v1.1.0, then v1.1.0 to v1.2.0, and so on. The table below shows the average generated pack size and the average CPU time consumed for each dataset, both before and after the patch: dataset | reflog | tags --------------------------------- before | 53358 | 2750977 size after | 32398 | 2668479 change | -39% | -3% --------------------------------- before | 0.18 | 1.12 CPU after | 0.18 | 1.15 change | +0% | +3% This patch makes a much bigger difference for packs with a shorter slice of history (since its effect is seen at the boundaries of the pack) though it has some benefit even for larger packs.
