Don't throw the memory allocated for remove_dir_recursively() away after a single call, use it for the other entries as well instead. This change was done before in deb8e15a (rm: reuse strbuf for all remove_dir_recursively() calls), but was reverted as a side-effect of 55856a35 (rm: absorb a submodules git dir before deletion).

2017-02-13ls-files: move only kept cache entries in prune_cache()René Scharfe
prune_cache() first identifies those entries at the start of the sorted array that can be discarded. Then it moves the rest of the entries up. Last it identifies the unwanted trailing entries among the moved ones and cuts them off. Change the order: Identify both start *and* end of the range to keep first and then move only those entries to the top. The resulting code is slightly shorter and a bit more efficient.

2017-02-13ls-files: pass prefix length explicitly to prune_cache()René Scharfe
The function prune_cache() relies on the fact that it is only called on max_prefix and sneakily uses the matching global variable max_prefix_len directly. Tighten its interface by passing both the string and its length as parameters. While at it move the NULL check into the function to collect all cache-pruning related logic in one place.

2017-01-31builtin/commit.c: switch to strbuf, instead of snprintf()Elia Pinto
Switch to dynamic allocation with strbuf, so we can avoid dealing with magic numbers in the code and reduce the cognitive burden from the programmers. The original code is correct, but programmers no longer have to count bytes needed for static allocation to know that. As a side effect of this change, we also reduce the snprintf() calls, that may silently truncate results if the programmer is not careful.

2017-01-31refs: add option core.logAllRefUpdates = alwaysCornelius Weig
When core.logallrefupdates is true, we only create a new reflog for refs that are under certain well-known hierarchies. The reason is that we know that some hierarchies (like refs/tags) are not meant to change, and that unknown hierarchies might not want reflogs at all (e.g., a hypothetical refs/foo might be meant to change often and drop old history immediately). However, sometimes it is useful to override this decision and simply log for all refs, because the safety and audit trail is more important than the performance implications of keeping the log around. This patch introduces a new "always" mode for the core.logallrefupdates option which will log updates to everything under refs/, regardless where in the hierarchy it is (we still will not log things like ORIG_HEAD and FETCH_HEAD, which are known to be transient).

2017-01-26fsck: lazily load types under --connectivity-onlyJeff King
The recent fixes to "fsck --connectivity-only" load all of the objects with their correct types. This keeps the connectivity-only code path close to the regular one, but it also introduces some unnecessary inefficiency. While getting the type of an object is cheap compared to actually opening and parsing the object (as the non-connectivity-only case would do), it's still not free. For reachable non-blob objects, we end up having to parse them later anyway (to see what they point to), making our type lookup here redundant. For unreachable objects, we might never hit them at all in the reachability traversal, making the lookup completely wasted. And in some cases, we might have quite a few unreachable objects (e.g., when alternates are used for shared object storage between repositories, it's normal for there to be objects reachable from other repositories but not the one running fsck). The comment in mark_object_for_connectivity() claims two benefits to getting the type up front: 1. We need to know the types during fsck_walk(). (And not explicitly mentioned, but we also need them when printing the types of broken or dangling commits). We can address this by lazy-loading the types as necessary. Most objects never need this lazy-load at all, because they fall into one of these categories: a. Reachable from our tips, and are coerced into the correct type as we traverse (e.g., a parent link will call lookup_commit(), which converts OBJ_NONE to OBJ_COMMIT). b. Unreachable, but not at the tip of a chunk of unreachable history. We only mention the tips as "dangling", so an unreachable commit which links to hundreds of other objects needs only report the type of the tip commit. 2. It serves as a cross-check that the coercion in (1a) is correct (i.e., we'll complain about a parent link that points to a blob). But we get most of this for free already, because right after coercing, we'll parse any non-blob objects. So we'd notice then if we expected a commit and got a blob. The one exception is when we expect a blob, in which case we never actually read the object contents. So this is a slight weakening, but given that the whole point of --connectivity-only is to sacrifice some data integrity checks for speed, this seems like an acceptable tradeoff. Here are before and after timings for an extreme case with ~5M reachable objects and another ~12M unreachable (it's the torvalds/linux repository on GitHub, connected to shared storage for all of the other kernel forks): [before] $ time git fsck --no-dangling --connectivity-only real 3m4.323s user 1m25.121s sys 1m38.710s [after] $ time git fsck --no-dangling --connectivity-only real 0m51.497s user 0m49.575s sys 0m1.776s Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2017-01-26fsck: move typename() printing to its own functionJeff King
When an object has a problem, we mention its type. But we do so by feeding the result of typename() directly to fprintf(). This is potentially dangerous because typename() can return NULL for some type values (like OBJ_NONE). It's doubtful that this can be triggered in practice with the current code, so this is probably not fixing a bug. But it future-proofs us against modifications that make things like OBJ_NONE more likely (and gives future patches a central point to handle them).

2017-01-19remote rename: more carefully determine whether a remote is configuredJohannes Schindelin
One of the really nice features of the ~/.gitconfig file is that users can override defaults by their own preferred settings for all of their repositories. One such default that some users like to override is whether the "origin" remote gets auto-pruned or not. The user would simply call git config --global remote.origin.prune true and from now on all "origin" remotes would be pruned automatically when fetching into the local repository. There is just one catch: now Git thinks that the "origin" remote is configured, even if the repository config has no [remote "origin"] section at all, as it does not realize that the "prune" setting was configured globally and that there really is no "origin" remote configured in this repository. That is a problem e.g. when renaming a remote to a new name, when Git may be fooled into thinking that there is already a remote of that new name. Let's fix this by paying more attention to *where* the remote settings came from: if they are configured in the local repository config, we must not overwrite them. If they were configured elsewhere, we cannot overwrite them to begin with, as we only write the repository config. There is only one caller of remote_is_configured() (in `git fetch`) that may want to take remotes into account even if they were configured outside the repository config; all other callers essentially try to prevent the Git command from overwriting settings in the repository config. To accommodate that fact, the remote_is_configured() function now requires a parameter that states whether the caller is interested in all remotes, or only in those that were configured in the repository config.

2017-01-19difftool: retire the scripted versionJohannes Schindelin

2017-01-19difftool: implement the functionality in the builtinJohannes Schindelin
This patch gives life to the skeleton added in the previous patch. The motivation for converting the difftool is that Perl scripts are not at all native on Windows, and that `git difftool` therefore is pretty slow on that platform, when there is no good reason for it to be slow. In addition, Perl does not really have access to Git's internals. That means that any script will always have to jump through unnecessary hoops, and it will often need to perform unnecessary work (e.g. when reading the entire config every time `git config` is called to query a single config value). The current version of the builtin difftool does not, however, make full use of the internals but instead chooses to spawn a couple of Git processes, still, to make for an easier conversion. There remains a lot of room for improvement, left later. Note: to play it safe, the original difftool is still called unless the config setting difftool.useBuiltin is set to true. The reason: this new, experimental, builtin difftool was shipped as part of Git for Windows v2.11.0, to allow for easier large-scale testing, but of course as an opt-in feature. The speedup is actually more noticable on Linux than on Windows: a quick test shows that t7800-difftool.sh runs in (2.183s/0.052s/0.108s) (real/user/sys) in a Linux VM, down from (6.529s/3.112s/0.644s), while on Windows, it is (36.064s/2.730s/7.194s), down from (47.637s/2.407s/6.863s). The culprit is most likely the overhead incurred from *still* having to shell out to mergetool-lib.sh and difftool--helper.sh. Still, it is an improvement.
