2021-01-07for-each-repo: do nothing on empty configLibravatar Derrick Stolee2-0/+13
'git for-each-repo --config=X' should return success without calling any subcommands when the config key 'X' has no value. The current implementation instead segfaults. A user could run into this issue if they used 'git maintenance start' to initialize their cron schedule using 'git for-each-repo --config=maintenance.repo ...' but then using 'git maintenance unregister' to remove the config option. (Note: 'git maintenance stop' would remove the config _and_ remove the cron schedule.) Add a simple test to ensure this works. Use 'git help --no-such-option' as the potential subcommand to ensure that we will hit a failure if the subcommand is ever run.

2021-01-06mergetool--lib: fix '--tool-help' to correctly show available toolsLibravatar Philippe Blain2-2/+15
Commit 83bbf9b92e (mergetool--lib: improve support for vimdiff-style tool variants, 2020-07-29) introduced a regression in the output of `git mergetool --tool-help` and `git difftool --tool-help` [1]. In function 'show_tool_names' in git-mergetool--lib.sh, we loop over the supported mergetools and their variants and accumulate them in the variable 'variants', separating them with a literal '\n'. The code then uses 'echo $variants' to turn these '\n' into newlines, but this behaviour is not portable, it just happens to work in some shells, like dash(1)'s 'echo' builtin. For shells in which 'echo' does not turn '\n' into newlines, the end result is that the only tools that are shown are the existing variants (except the last variant alphabetically), since the variants are separated by actual newlines in '$variants' because of the several 'echo' calls in mergetools/{bc,vimdiff}::list_tool_variants. Fix this bug by embedding an actual line feed into `variants` in show_tool_names(). While at it, replace `sort | uniq` by `sort -u`. To prevent future regressions, add a simple test that checks that a few known tools are correctly shown (let's avoid counting the total number of tools to lessen the maintenance burden when new tools are added or if '--tool-help' learns additional logic, like hiding tools depending on the current platform).

2021-01-06t4129: don't fail if setgid is set in the test directoryLibravatar Matheus Tavares1-2/+7
The last test of t4129 creates a directory and expects its setgid bit (g+s) to be off. But this makes the test fail when the parent directory has the bit set, as setgid's state is inherited by newly created subdirectories. One way to solve this problem is to allow the presence of this bit when comparing the return of `test_modebits` with the expected value. But then we may have the same problem in the future when other tests start using `test_modebits` on directories (currently t4129 is the only one) and forget about setgid. Instead, let's make the helper function more robust with respect to the state of the setgid bit in the test directory by removing this bit from the returning value. There should be no problem with existing callers as no one currently expects this bit to be on. Note that the sticky bit (+t) and the setuid bit (u+s) are not inherited, so we don't have to worry about those.

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 Stolee3-1/+226
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 Stolee3-1/+286
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.

2021-01-04revision: trace topo-walk statisticsLibravatar Derrick Stolee1-0/+31
We trace statistics about the effectiveness of changed-path Bloom filters since 42e50e78 (revision.c: add trace2 stats around Bloom filter usage, 2020-04-06). Add similar tracing for the topo-walk algorithm that uses generation numbers to limit the walk size. This information can help investigate and describe benefits to heuristics and other changes. The information that is printed is in JSON format and can be formatted nicely to present as follows: { "count_explort_walked":2603, "count_indegree_walked":2603, "count_topo_walked":473 } Each of these values count the number of commits are visited by each of the three "stages" of the topo-walk as detailed in b4542418 (revision.c: generation-based topo-order algorithm, 2018-11-01).

2021-01-04sha1-lookup: rename `sha1_pos()` as `hash_pos()`Libravatar Martin Ågren8-15/+15
Rename this function to reflect that we're not just able to handle SHA-1 these days. There are a few instances of "sha1" left in sha1-lookup.[ch] after this, but those will be addressed in the next commit.
