2017-04-23completion: expand "push --delete <remote> <ref>" for refs on that <remote>Libravatar Ævar Arnfjörð Bjarmason1-0/+34
Change the completion of "push --delete <remote> <ref>" to complete refs on that <remote>, not all refs. Before this cloning git.git and doing "git push --delete origin p<TAB>" will complete nothing, since a fresh clone of git.git will have no "pu" branch, whereas origin/p<TAB> will uselessly complete origin/pu, but fully qualified references aren't accepted by "--delete". Now p<TAB> will complete as "pu". The completion of giving --delete later, e.g. "git push origin --delete p<TAB>" remains unchanged, this is a bug, but is a general existing limitation of the bash completion, and not how git-push is documented, so I'm not fixing that case, but adding a failing TODO test for it.

2017-04-20worktree add: add --lock optionLibravatar Nguyễn Thái Ngọc Duy1-0/+6
As explained in the document. This option has an advantage over the command sequence "git worktree add && git worktree lock": there will be no gap that somebody can accidentally "prune" the new worktree (or soon, explicitly "worktree remove" it). "worktree add" does keep a lock on while it's preparing the worktree. If --lock is specified, this lock remains after the worktree is created.

Created t/perf/repos/many-files.sh to generate large, but artificial repositories. Created t/perf/inflate-repo.sh to alter an EXISTING repo to have a set of large commits. This can be used to create a branch with 1M+ files in repositories like git.git or linux.git, but with more realistic content. It does this by making multiple copies of the entire worktree in a series of sub-directories. The branch name and ballast structure created by both scripts match, so either script can be used to generate very large test repositories for the following perf test. Created t/perf/p0006-read-tree-checkout.sh to measure performance on various read-tree, checkout, and update-index operations. This test can run using either normal repos or ones from the above scripts. Signed-off-by: Jeff Hostetler <jeffhost@microsoft.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2017-04-19config: correct file reading order in read_early_config()Libravatar Nguyễn Thái Ngọc Duy1-0/+18
Config file reading order is important because each file can override values in the previous files and this is expected behavior. Normally we read in this order, all in do_git_config_sequence(): 1. $HOME/.gitconfig 2. $GIT_DIR/config 3. config from command line However in read_early_config() the order may be swapped a bit if setup_git_directory() has not been called: 1. $HOME/.gitconfig 2. $GIT_DIR/config is NOT read because .git dir is not found _yet_ 3. config from command line 4. $GIT_DIR/config is now READ (after discover_git_directory() call) The reading at step 4 could override config at step 3, which is not the expectation. Now that we could pass the .git dir around, we could feed discover_git_directory() back to step 2, so that it works again, and remove step 4.

2017-04-18ls-files: fix path used when recursing into submodulesLibravatar Jacob Keller1-0/+11
Don't assume that the current working directory is the root of the repository. Correctly generate the path for the recursing child processes by building it from the work_tree() root instead. Otherwise if we run ls-files using --git-dir or --work-tree it will not work correctly as it attempts to change directory into a potentially invalid location. Best case, it doesn't exist and we produce an error. Worst case we cd into the wrong location and unknown behavior occurs. Add a new test which highlights this possibility.

2017-04-17config: handle conditional include when $GIT_DIR is not set upLibravatar Nguyễn Thái Ngọc Duy1-0/+11
If setup_git_directory() and friends have not been called, get_git_dir() (because of includeIf.gitdir:XXX) would lead to die("BUG: setup_git_env called without repository"); There are two cases when a config file could be read before $GIT_DIR is located. The first one is check_repository_format(), where we read just the one file $GIT_DIR/config to check if we could understand this repository. This case should be safe. We do not parse include directives, which can only be triggered from git_config_with_options, but setup code uses a lower-level function. The concerned variables should never be hidden away behind includes anyway. The second one is triggered in check_pager_config() when we're about to run an external git command. We might be able to find $GIT_DIR in this case, which is exactly what read_early_config() does (and also is what check_pager_config() uses). Conditional includes and get_git_dir() could be triggered by the first git_config_with_options() call there, before discover_git_directory() is used as a fallback $GIT_DIR detection. Detect this special "early reading" case, pass down the $GIT_DIR, either from previous setup or detected by discover_git_directory(), and make conditional include use it.

2017-04-17ls-files: fix recurse-submodules with nested submodulesLibravatar Jacob Keller1-0/+1
Since commit e77aa336f116 ("ls-files: optionally recurse into submodules", 2016-10-07) ls-files has known how to recurse into submodules when displaying files. Unfortunately this fails for certain cases, including when nesting more than one submodule, called from within a submodule that itself has submodules, or when the GIT_DIR environemnt variable is set. Prior to commit b58a68c1c187 ("setup: allow for prefix to be passed to git commands", 2017-03-17) this resulted in an error indicating that --prefix and --super-prefix were incompatible. After this commit, instead, the process loops forever with a GIT_DIR set to the parent and continuously reads the parent submodule files and recursing forever. Fix this by preparing the environment properly for submodules when setting up the child process. This is similar to how other commands such as grep behave. This was not caught by the original tests because the scenario is avoided if the submodules are created separately and not stored as the standard method of putting the submodule git directory under .git/modules/<name>. We can update the test to show the failure by the addition of "git submodule absorbgitdirs" to the test case. However, note that this new test would run forever without the necessary fix in this patch. Signed-off-by: Jacob Keller <jacob.keller@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2017-04-16t6500: wait for detached auto gc at the end of the test scriptLibravatar SZEDER Gábor1-1/+17
The last test in 't6500-gc', 'background auto gc does not run if gc.log is present and recent but does if it is old', added in a831c06a2 (gc: ignore old gc.log files, 2017-02-10), may sporadically trigger an error message from the test harness: rm: cannot remove 'trash directory.t6500-gc/.git/objects': Directory not empty The test in question ends with executing an auto gc in the backround, which occasionally takes so long that it's still running when 'test_done' is about to remove the trash directory. This 'rm -rf $trash' in the foreground might race with the detached auto gc to create and delete files and directories, and gc might (re-)create a path that 'rm' already visited and removed, triggering the above error message when 'rm' attempts to remove its parent directory. Commit bb05510e5 (t5510: run auto-gc in the foreground, 2016-05-01) fixed the same problem in a different test script by simply disallowing background gc. Unfortunately, what worked there is not applicable here, because the purpose of this test is to check the behavior of a detached auto gc. Make sure that the test doesn't continue before the gc is finished in the background with a clever bit of shell trickery: - Open fd 9 in the shell, to be inherited by the background gc process, because our daemonize() only closes the standard fds 0, 1 and 2. - Duplicate this fd 9 to stdout. - Read 'git gc's stdout, and thus fd 9, through a command substitution. We don't actually care about gc's output, but this construct has two useful properties: - This read blocks until stdout or fd 9 are open. While stdout is closed after the main gc process creates the background process and exits, fd 9 remains open until the backround process exits. - The variable assignment from the command substitution gets its exit status from the command executed within the command substitution, i.e. a failing main gc process will cause the test to fail. Note, that this fd trickery doesn't work on Windows, because due to MSYS limitations the git process only inherits the standard fds 0, 1 and 2 from the shell. Luckily, it doesn't matter in this case, because on Windows daemonize() is basically a noop, thus 'git gc --auto' always runs in the foreground. And since we can now continue the test reliably after the detached gc finished, check that there is only a single packfile left at the end, i.e. that the detached gc actually did what it was supposed to do. Also add a comment at the end of the test script to warn developers of future tests about this issue of long running detached gc processes.

2017-04-16connect.c: handle errors from split_cmdlineLibravatar Jeff King1-0/+6
Commit e9d9a8a4d (connect: handle putty/plink also in GIT_SSH_COMMAND, 2017-01-02) added a call to split_cmdline(), but checks only for a non-zero return to see if we got any output. Since the function returns negative values (and a NULL argv) on error, we end up dereferencing NULL and segfaulting. Arguably we could report on the parsing error here, but it's probably not worth it. This is a best-effort attempt to see if we are using plink. So we can simply return here with "no, it wasn't plink" and let the shell actually complain about the bogus quoting.

2017-04-15string-list: use ALLOC_GROW macro when reallocing string_listLibravatar Jeff Hostetler1-0/+49
Use ALLOC_GROW() macro when reallocing a string_list array rather than simply increasing it by 32. This is a performance optimization. During status on a very large repo and there are many changes, a significant percentage of the total run time is spent reallocing the wt_status.changes array. This change decreases the time in wt_status_collect_changes_worktree() from 125 seconds to 45 seconds on my very large repository. This produced a modest gain on my 1M file artificial repo, but broke even on linux.git.

2017-04-15read-cache: force_verify_index_checksumLibravatar Jeff Hostetler1-0/+13
Teach git to skip verification of the SHA1-1 checksum at the end of the index file in verify_hdr() which is called from read_index() unless the "force_verify_index_checksum" global variable is set. Teach fsck to force this verification. The checksum verification is for detecting disk corruption, and for small projects, the time it takes to compute SHA-1 is not that significant, but for gigantic repositories this calculation adds significant time to every command. These effect can be seen using t/perf/p0002-read-cache.sh: Test HEAD~1 HEAD -------------------------------------------------------------------------------------- 0002.1: read_cache/discard_cache 1000 times 0.66(0.44+0.20) 0.30(0.27+0.02) -54.5% Signed-off-by: Jeff Hostetler <jeffhost@microsoft.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
