2021-01-06p7519: allow running without watchman prereqLibravatar Taylor Blau1-1/+6
p7519 measures the performance of the fsmonitor code. To do this, it uses the installed copy of Watchman. If Watchman isn't installed, a noop integration script is installed in its place. When in the latter mode, it is expected that the script should not write a "last update token": in fact, it doesn't write anything at all since the script is blank. Commit 33226af42b (t/perf/fsmonitor: improve error message if typoing hook name, 2020-10-26) made sure that running 'git update-index --fsmonitor' did not write anything to stderr, but this is not the case when using the empty Watchman script, since Git will complain that: $ which watchman watchman not found $ cat .git/hooks/fsmonitor-empty $ git -c core.fsmonitor=.git/hooks/fsmonitor-empty update-index --fsmonitor warning: Empty last update token. Prior to 33226af42b, the output wasn't checked at all, which allowed this noop mode to work. But, 33226af42b breaks p7519 when running it without a 'watchman(1)' on your system. Handle this by only checking that the stderr is empty only when running with a real watchman executable. Otherwise, assert that the error message is the expected one when running in the noop mode.

2021-01-05maintenance: use Windows scheduled tasksLibravatar Derrick Stolee1-0/+37
Git's background maintenance uses cron by default, but this is not available on Windows. Instead, integrate with Task Scheduler. Tasks can be scheduled using the 'schtasks' command. There are several command-line options that can allow for some advanced scheduling, but unfortunately these seem to all require authenticating using a password. Instead, use the "/xml" option to pass an XML file that contains the configuration for the necessary schedule. These XML files are based on some that I exported after constructing a schedule in the Task Scheduler GUI. These options only run background maintenance when the user is logged in, and more fields are populated with the current username and SID at run-time by 'schtasks'. Since the GIT_TEST_MAINT_SCHEDULER environment variable allows us to specify 'schtasks' as the scheduler, we can test the Windows-specific logic on other platforms. Thus, add a check that the XML file written by Git is valid when xmllint exists on the system. Since we use a temporary file for the XML files sent to 'schtasks', we prefix the random characters with the frequency so it is easier to examine the proper file during tests. Instead of an exact match on the 'args' file, we 'grep' for the arguments other than the filename. There is a deficiency in the current design. Windows has two kinds of applications: GUI applications that start by "winmain()" and console applications that start by "main()". Console applications are attached to a new Console window if they are not already associated with a GUI application. This means that every hour the scheudled task launches a command window for the scheduled tasks. Not only is this visually obtrusive, but it also takes focus from whatever else the user is doing! A simple fix would be to insert a GUI application that acts as a shim between the scheduled task and Git. This is currently possible in Git for Windows by setting the <Command> tag equal to C:\Program Files\Git\git-bash.exe with options "--hide --no-needs-console --command=cmd\git.exe" followed by the arguments currently used. Since git-bash.exe is not included in Windows builds of core Git, I chose to leave out this feature. My plan is to submit a small patch to Git for Windows that converts the use of git.exe with this use of git-bash.exe in the short term. In the long term, we can consider creating this GUI shim application within core Git, perhaps in contrib/.

2021-01-05maintenance: use launchctl on macOSLibravatar Derrick Stolee1-0/+59
The existing mechanism for scheduling background maintenance is done through cron. The 'crontab -e' command allows updating the schedule while cron itself runs those commands. While this is technically supported by macOS, it has some significant deficiencies: 1. Every run of 'crontab -e' must request elevated privileges through the user interface. When running 'git maintenance start' from the Terminal app, it presents a dialog box saying "Terminal.app would like to administer your computer. Administration can include modifying passwords, networking, and system settings." This is more alarming than what we are hoping to achieve. If this alert had some information about how "git" is trying to run "crontab" then we would have some reason to believe that this dialog might be fine. However, it also doesn't help that some scenarios just leave Git waiting for a response without presenting anything to the user. I experienced this when executing the command from a Bash terminal view inside Visual Studio Code. 2. While cron initializes a user environment enough for "git config --global --show-origin" to show the correct config file information, it does not set up the environment enough for Git Credential Manager Core to load credentials during a 'prefetch' task. My prefetches against private repositories required re-authenticating through UI pop-ups in a way that should not be required. The solution is to switch from cron to the Apple-recommended [1] 'launchd' tool. [1] https://developer.apple.com/library/archive/documentation/MacOSX/Conceptual/BPSystemStartup/Chapters/ScheduledJobs.html The basics of this tool is that we need to create XML-formatted "plist" files inside "~/Library/LaunchAgents/" and then use the 'launchctl' tool to make launchd aware of them. The plist files include all of the scheduling information, along with the command-line arguments split across an array of <string> tags. For example, here is my plist file for the weekly scheduled tasks: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"><dict> <key>Label</key><string>org.git-scm.git.weekly</string> <key>ProgramArguments</key> <array> <string>/usr/local/libexec/git-core/git</string> <string>--exec-path=/usr/local/libexec/git-core</string> <string>for-each-repo</string> <string>--config=maintenance.repo</string> <string>maintenance</string> <string>run</string> <string>--schedule=weekly</string> </array> <key>StartCalendarInterval</key> <array> <dict> <key>Day</key><integer>0</integer> <key>Hour</key><integer>0</integer> <key>Minute</key><integer>0</integer> </dict> </array> </dict> </plist> The schedules for the daily and hourly tasks are more complicated since we need to use an array for the StartCalendarInterval with an entry for each of the six days other than the 0th day (to avoid colliding with the weekly task), and each of the 23 hours other than the 0th hour (to avoid colliding with the daily task). The "Label" value is currently filled with "org.git-scm.git.X" where X is the frequency. We need a different plist file for each frequency. The launchctl command needs to be aligned with a user id in order to initialize the command environment. This must be done using the 'launchctl bootstrap' subcommand. This subcommand is new as of macOS 10.11, which was released in September 2015. Before that release the 'launchctl load' subcommand was recommended. The best source of information on this transition I have seen is available at [2]. The current design does not preclude a future version that detects the available fatures of 'launchctl' to use the older commands. However, it is best to rely on the newest version since Apple might completely remove the deprecated version on short notice. [2] https://babodee.wordpress.com/2016/04/09/launchctl-2-0-syntax/ To remove a schedule, we must run 'launchctl bootout' with a valid plist file. We also need to 'bootout' a task before the 'bootstrap' subcommand will succeed, if such a task already exists. The need for a user id requires us to run 'id -u' which works on POSIX systems but not Windows. Further, the need for fully-qualitifed path names including $HOME behaves differently in the Git internals and the external test suite. The $HOME variable starts with "C:\..." instead of the "/c/..." that is provided by Git in these subcommands. The test therefore has a prerequisite that we are not on Windows. The cross- platform logic still allows us to test the macOS logic on a Linux machine. We can verify the commands that were run by 'git maintenance start' and 'git maintenance stop' by injecting a script that writes the command-line arguments into GIT_TEST_MAINT_SCHEDULER. An earlier version of this patch accidentally had an opening "<dict>" tag when it should have had a closing "</dict>" tag. This was caught during manual testing with actual 'launchctl' commands, but we do not want to update developers' tasks when running tests. It appears that macOS includes the "xmllint" tool which can verify the XML format. This is useful for any system that might contain the tool, so use it whenever it is available. We strive to make these tests work on all platforms, but Windows caused some headaches. In particular, the value of getuid() called by the C code is not guaranteed to be the same as `$(id -u)` invoked by a test. This is because `git.exe` is a native Windows program, whereas the utility programs run by the test script mostly utilize the MSYS2 runtime, which emulates a POSIX-like environment. Since the purpose of the test is to check that the input to the hook is well-formed, the actual user ID is immaterial, thus we can work around the problem by making the the test UID-agnostic. Another subtle issue is the $HOME environment variable being a Windows-style path instead of a Unix-style path. We can be more flexible here instead of expecting exact path matches.

2021-01-04completion: add proper public __git_completeLibravatar Felipe Contreras1-1/+13
When __git_complete was introduced, it was meant to be temporarily, while a proper guideline for public shell functions was established (tentatively _GIT_complete), but since that never happened, people in the wild started to use __git_complete, even though it was marked as not public. Eight years is more than enough wait, let's mark this function as public, and make it a bit more user-friendly. So that instead of doing: __git_complete gk __gitk_main The user can do: __git_complete gk gitk And instead of: __git_complete gf _git_fetch Do: __git_complete gf git_fetch Backwards compatibility is maintained.

2021-01-04t6016: move to lib-log-graph.sh frameworkLibravatar Antonio Russo1-187/+167
t6016 manually reconstructs git log --graph output by using the reported commit hashes from `git rev-parse`. Each tag is converted into an environment variable manually, and then `echo`-ed to an expected output file, which is in turn compared to the actual output. The expected output is difficult to read and write, because, e.g., each line of output must be prefaced with echo, quoted, and properly escaped. Additionally, the test is sensitive to trailing whitespace, which may potentially be removed from graph log output in the future. In order to reduce duplication, ease troubleshooting of failed tests by improving readability, and ease the addition of more tests to this file, port the operations to `lib-log-graph.sh`, which is already used in several other tests, e.g., t4215. Give all merges a simple commit message, and use a common `check_graph` macro taking a heredoc of the expected output which does not required extensive escaping.

test_export() has been self-recursive since its inception even though a simple for-loop would have served just as well to append its arguments to the `test_export_` variable separated by the pipe character "|". Recently `test_export_` was changed instead to a space-separated list of tokens to be exported, an operation which can be accomplished via a single simple assignment, with no need for looping or recursion. Therefore, simplify the implementation. While at it, take advantage of the fact that variable names to be exported are shell identifiers, thus won't be composed of special characters or whitespace, thus simple a `$*` can be used rather than magical `"$@"`.

2020-12-21gc: fix handling of crontab magic markersLibravatar Martin Ågren1-0/+7
On `git maintenance start`, we add a few entries to the user's cron table. We wrap our entries using two magic markers, "# BEGIN GIT MAINTENANCE SCHEDULE" and "# END GIT MAINTENANCE SCHEDULE". At a later `git maintenance stop`, we will go through the table and remove these lines. Or rather, we will remove the "BEGIN" marker, the "END" marker and everything between them. Alas, we have a bug in how we detect the "END" marker: we don't. As we loop through all the lines of the crontab, if we are in the "old region", i.e., the region we're aiming to remove, we make an early `continue` and don't get as far as checking for the "END" marker. Thus, once we've seen our "BEGIN", we remove everything until the end of the file. Rewrite the logic for identifying these markers. There are four cases that are mutually exclusive: The current line starts a region or it ends it, or it's firmly within the region, or it's outside of it (and should be printed).

For instance, if a linked worktree is moved (without using `git worktree move`), repair is possible because the worktree still knows the location of the repository even though the repository no longer knows where the worktree is. Similarly, if the repository is moved, repair is possible since the repository still knows the locations of the worktrees even though the worktrees no longer know where the repository is. However, if both the repository and the worktrees are moved, then links are severed in both directions, and no repair is possible. This is the case even when the new worktree locations are specified as arguments to `git worktree repair`. The reason for this limitation is twofold. First, when `repair` consults the worktree's gitfile (/path/to/worktree/.git) to determine the corresponding <repo>/worktrees/<id>/gitdir file to fix, <repo> is the old path to the repository, thus it is unable to fix the `gitdir` file at its new location since it doesn't know where it is. Second, when `repair` consults <repo>/worktrees/<id>/gitdir to find the location of the worktree's gitfile (/path/to/worktree/.git), the path recorded in `gitdir` is the old location of the worktree's gitfile, thus it is unable to repair the gitfile since it doesn't know where it is. Fix these shortcomings by teaching `repair` to attempt to infer the new location of the <repo>/worktrees/<id>/gitdir file when the location recorded in the worktree's gitfile has become stale but the file is otherwise well-formed. The inference is intentionally simple-minded. For each worktree path specified as an argument, `git worktree repair` manually reads the ".git" gitfile at that location and, if it is well-formed, extracts the <id>. It then searches for a corresponding <id> in <repo>/worktrees/ and, if found, concludes that there is a reasonable match and updates <repo>/worktrees/<id>/gitdir to point at the specified worktree path. In order for <repo> to be known, `git worktree repair` must be run in the main worktree or bare repository. `git worktree repair` first attempts to repair each incoming /path/to/worktree/.git gitfile to point at the repository, and then attempts to repair outgoing <repo>/worktrees/<id>/gitdir files to point at the worktrees. This sequence was chosen arbitrarily when originally implemented since the order of fixes is immaterial as long as one side of the two-way link between the repository and a worktree is sound. However, for this new repair technique to work, the order must be reversed. This is because the new inference mechanism, when it is successful, allows the outgoing <repo>/worktrees/<id>/gitdir file to be repaired, thus fixing one side of the two-way link. Once that side is fixed, the other side can be fixed by the existing repair mechanism, hence the order of repairs is now significant. Two safeguards are employed to avoid hijacking a worktree from a different repository if the user accidentally specifies a foreign worktree as an argument. The first, as described above, is that it requires an <id> match between the repository and the worktree. That itself is not foolproof for preventing hijack, so the second safeguard is that the inference will only kick in if the worktree's /path/to/worktree/.git gitfile does not point at a repository.

2020-12-21test: bisect-porcelain: fix location of filesLibravatar Felipe Contreras1-8/+8
Commit ba7eafe146 (t6030: explicitly test for bisection cleanup, 2017-09-29) introduced checks for files in the $GIT_DIR directory, but that variable is not always defined, and in this test file it's not. Therefore these checks always passed regardless of the presence of these files (unless the user has some /BISECT_LOG file, for some reason). Let's check the files in the correct location.

2020-12-16pack-redundant: fix crash when one packfile in repoLibravatar Jiang Xin1-4/+33
Command `git pack-redundant --all` will crash if there is only one packfile in the repository. This is because, if there is only one packfile in local_packs, `cmp_local_packs` will do nothing and will leave `pl->unique_objects` as uninitialized. Also add testcases for repository with no packfile and one packfile in t5323. Reported-by: Daniel C.
