2022-03-30branch: support more tracking modes when recursingLibravatar Glen Choo1-3/+4
"git branch --recurse-submodules" does not propagate "--track=inherit" or "--no-track" to submodules, which causes submodule branches to use the wrong tracking mode [1]. To fix this, pass the correct options to the "submodule--helper create-branch" child process and test for it. While we are refactoring the same code, replace "--track" with the synonymous, but more consistent-looking "--track=direct" option (introduced at the same time as "--track=inherit", d3115660b4 (branch: add flags and config to inherit tracking, 2021-12-20)). [1] This bug is partially a timing issue: "branch --recurse-submodules" was introduced around the same time as "--track=inherit", and even though I rebased "branch --recurse-submodules" on top of that, I had neglected to support the new tracking mode. Omitting "--no-track" was just a plain old mistake, though. Signed-off-by: Glen Choo <chooglen@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2022-03-28reflog: fix 'show' subcommand's argvLibravatar SZEDER Gábor1-2/+2
cmd_reflog() invokes parse_options() with PARSE_OPT_KEEP_ARGV0, but it doesn't account for the retained argv[0] before invoking cmd_reflog_show() to handle the 'git reflog show' subcommand. Consequently, cmd_reflog_show() always gets an 'argv' array starting with elements argv[0]="reflog" and argv[1]="show". Strip the name of the git command from the 'argv' array before passing it to the function handling the 'show' subcommand. There is no user-visible bug here, because cmd_reflog_show() doesn't have any options or parameters of its own.

2022-03-28pack-objects: lazily set up "struct rev_info", don't leakLibravatar Ævar Arnfjörð Bjarmason1-5/+23
In the preceding [1] (pack-objects: move revs out of get_object_list(), 2022-03-22) the "repo_init_revisions()" was moved to cmd_pack_objects() so that it unconditionally took place for all invocations of "git pack-objects". We'd thus start leaking memory, which is easily reproduced in e.g. git.git by feeding e83c5163316 (Initial revision of "git", the information manager from hell, 2005-04-07) to "git pack-objects"; $ echo e83c5163316f89bfbde7d9ab23ca2e25604af290 | ./git pack-objects initial [...] ==19130==ERROR: LeakSanitizer: detected memory leaks Direct leak of 7120 byte(s) in 1 object(s) allocated from: #0 0x455308 in __interceptor_malloc (/home/avar/g/git/git+0x455308) #1 0x75b399 in do_xmalloc /home/avar/g/git/wrapper.c:41:8 #2 0x75b356 in xmalloc /home/avar/g/git/wrapper.c:62:9 #3 0x5d7609 in prep_parse_options /home/avar/g/git/diff.c:5647:2 #4 0x5d415a in repo_diff_setup /home/avar/g/git/diff.c:4621:2 #5 0x6dffbb in repo_init_revisions /home/avar/g/git/revision.c:1853:2 #6 0x4f599d in cmd_pack_objects /home/avar/g/git/builtin/pack-objects.c:3980:2 #7 0x4592ca in run_builtin /home/avar/g/git/git.c:465:11 #8 0x457d81 in handle_builtin /home/avar/g/git/git.c:718:3 #9 0x458ca5 in run_argv /home/avar/g/git/git.c:785:4 #10 0x457b40 in cmd_main /home/avar/g/git/git.c:916:19 #11 0x562259 in main /home/avar/g/git/common-main.c:56:11 #12 0x7fce792ac7ec in __libc_start_main csu/../csu/libc-start.c:332:16 #13 0x4300f9 in _start (/home/avar/g/git/git+0x4300f9) SUMMARY: LeakSanitizer: 7120 byte(s) leaked in 1 allocation(s). Aborted Narrowly fixing that commit would have been easy, just add call repo_init_revisions() right before get_object_list(), which is effectively what was done before that commit. But an unstated constraint when setting it up early is that it was needed for the subsequent [2] (pack-objects: parse --filter directly into revs.filter, 2022-03-22), i.e. we might have a --filter command-line option, and need to either have the "struct rev_info" setup when we encounter that option, or later. Let's just change the control flow so that we'll instead set up the "struct rev_info" only when we need it. Doing so leads to a bit more verbosity, but it's a lot clearer what we're doing and why. An earlier version of this commit[3] went behind opt_parse_list_objects_filter()'s back by faking up a "struct option" before calling it. Let's avoid that and instead create a blessed API for this pattern. We could furthermore combine the two get_object_list() invocations here by having repo_init_revisions() invoked on &pfd.revs, but I think clearly separating the two makes the flow clearer. Likewise redundantly but explicitly (i.e. redundant v.s. a "{ 0 }") "0" to "have_revs" early in cmd_pack_objects(). While we're at it add parentheses around the arguments to the OPT_* macros in in list-objects-filter-options.h, as we need to change those lines anyway. It doesn't matter in this case, but is good general practice. 1. https://lore.kernel.org/git/619b757d98465dbc4995bdc11a5282fbfcbd3daa.1647970119.git.gitgitgadget@gmail.com 2. https://lore.kernel.org/git/97de926904988b89b5663bd4c59c011a1723a8f5.1647970119.git.gitgitgadget@gmail.com 3. https://lore.kernel.org/git/patch-1.1-193534b0f07-20220325T121715Z-avarab@gmail.com/ Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2022-03-25fsmonitor--daemon: use a cookie file to sync with file systemLibravatar Jeff Hostetler1-1/+236
Teach fsmonitor--daemon client threads to create a cookie file inside the .git directory and then wait until FS events for the cookie are observed by the FS listener thread. This helps address the racy nature of file system events by blocking the client response until the kernel has drained any event backlog. This is especially important on MacOS where kernel events are only issued with a limited frequency. See the `latency` argument of `FSeventStreamCreate()`. The kernel only signals every `latency` seconds, but does not guarantee that the kernel queue is completely drained, so we may have to wait more than one interval. If we increase the latency, the system is more likely to drop events. We avoid these issues by having each client thread create a unique cookie file and then wait until it is seen in the event stream.

2022-03-25fsmonitor--daemon: periodically truncate list of modified filesLibravatar Jeff Hostetler1-0/+88
Teach fsmonitor--daemon to periodically truncate the list of modified files to save some memory. Clients will ask for the set of changes relative to a token that they found in the FSMN index extension in the index. (This token is like a point in time, but different). Clients will then update the index to contain the response token (so that subsequent commands will be relative to this new token). Therefore, the daemon can gradually truncate the in-memory list of changed paths as they become obsolete (older than the previous token). Since we may have multiple clients making concurrent requests with a skew of tokens and clients may be racing to the talk to the daemon, we lazily truncate the list. We introduce a 5 minute delay and truncate batches 5 minutes after they are considered obsolete.

2022-03-25fsmonitor--daemon: create token-based changed path cacheLibravatar Jeff Hostetler1-2/+228
Teach fsmonitor--daemon to build a list of changed paths and associate them with a token-id. This will be used by the platform-specific backends to accumulate changed paths in response to filesystem events. The platform-specific file system listener thread receives file system events containing one or more changed pathnames (with whatever bucketing or grouping that is convenient for the file system). These paths are accumulated (without locking) by the file system layer into a `fsmonitor_batch`. When the file system layer has drained the kernel event queue, it will "publish" them to our token queue and make them visible to concurrent client worker threads. The token layer is free to combine and/or de-dup paths within these batches for efficient presentation to clients.

Teach fsmonitor--daemon to classify relative and absolute pathnames and decide how they should be handled. This will be used by the platform-specific backend to respond to each filesystem event. When we register for filesystem notifications on a directory, we get events for everything (recursively) in the directory. We want to report to clients changes to tracked and untracked paths within the working directory proper. We do not want to report changes within the .git directory, for example. This classification will be used in a later commit by the different backends to classify paths as events are received.

2022-03-25fsmonitor--daemon: implement 'start' commandLibravatar Jeff Hostetler1-2/+107
Implement 'git fsmonitor--daemon start' command. This command starts an instance of 'git fsmonitor--daemon run' in the background using the new 'start_bg_command()' function. We avoid the fork-and-call technique on Unix systems in favor of a fork-and-exec technique. This gives us more uniform Trace2 child-* events. It also makes our usage more consistent with Windows usage. On Windows, teach 'git fsmonitor--daemon run' to optionally call 'FreeConsole()' to release handles to the inherited Win32 console (despite being passed invalid handles for stdin/out/err). Without this, command prompts and powershell terminal windows could hang in "exit" until the last background child process exited or released their Win32 console handle. (This was not seen with git-bash shells because they don't have a Win32 console attached to them.)

2022-03-25fsmonitor: config settings are repository-specificLibravatar Jeff Hostetler1-2/+5
Move fsmonitor config settings to a new and opaque `struct fsmonitor_settings` structure. Add a lazily-loaded pointer to this into `struct repo_settings` Create an `enum fsmonitor_mode` type in `struct fsmonitor_settings` to represent the state of fsmonitor. This lets us represent which, if any, fsmonitor provider (hook or IPC) is enabled. Create `fsm_settings__get_*()` getters to lazily look up fsmonitor- related config settings. Get rid of the `core_fsmonitor` global variable. Move the code to lookup the existing `core.fsmonitor` config value into the fsmonitor settings. Create a hook pathname variable in `struct fsmonitor-settings` and only set it when in hook mode. Extend the definition of `core.fsmonitor` to be either a boolean or a hook pathname. When true, the builtin FSMonitor is used. When false or unset, no FSMonitor (neither builtin nor hook) is used. The existing `core_fsmonitor` global variable was used to store the pathname to the fsmonitor hook *and* it was used as a boolean to see if fsmonitor was enabled. This dual usage and global visibility leads to confusion when we add the IPC-based provider. So lets hide the details in fsmonitor-settings.c and let it decide which provider to use in the case of multiple settings. This avoids cluttering up repo-settings.c with these private details. A future commit in builtin-fsmonitor series will add the ability to disqualify worktrees for various reasons, such as being mounted from a remote volume, where fsmonitor should not be started. Having the config settings hidden in fsmonitor-settings.c allows such worktree restrictions to override the config values used.

The 'reset.refresh' option was introduced in 101cee42dd (reset: introduce --[no-]refresh option to --mixed, 2022-03-11) as a replacement for the refresh-skipping behavior originally controlled by 'reset.quiet'. Although 'reset.refresh=false' functionally served the same purpose as 'reset.quiet=true', it exposed [1] the fact that the existence of a global "skip refresh" option could potentially cause problems for users. Allowing a global config option to avoid refreshing the index forces scripts using 'git reset --mixed' to defensively use '--refresh' if index refresh is expected; if that option is missing, behavior of a script could vary from user-to-user without explanation. Furthermore, globally disabling index refresh in 'reset --mixed' was initially devised as a passive performance improvement; since the introduction of the option, other changes have been made to Git (e.g., the sparse index) with a greater potential performance impact without sacrificing index correctness. Therefore, we can more aggressively err on the side of correctness and limit the cases of skipping index refresh to only when a user specifies the '--no-refresh' option.

2022-03-23reset: remove 'reset.quiet' config optionLibravatar Victoria Dye1-1/+0
Remove the 'reset.quiet' config option, remove '--no-quiet' documentation in 'Documentation/git-reset.txt'. In 4c3abd0551 (reset: add new reset.quiet config setting, 2018-10-23), 'reset.quiet' was introduced as a way to globally change the default behavior of 'git reset --mixed' to skip index refresh. However, now that '--quiet' does not affect index refresh, 'reset.quiet' would only serve to globally silence logging. This was not the original intention of the config setting, and there's no precedent for such a setting in other commands with a '--quiet' option, so it appears to be obsolete. In addition to the options & its documentation, remove 'reset.quiet' from the recommended config for 'scalar'.

2022-03-23reset: do not make '--quiet' disable index refreshLibravatar Victoria Dye1-8/+1
Update '--quiet' to no longer implicitly skip refreshing the index in a mixed reset. Users now have the ability to explicitly disable refreshing the index with the '--no-refresh' option, so they no longer need to use '--quiet' to do so. Moreover, we explicitly remove the refresh-skipping behavior from '--quiet' because it is completely unrelated to the stated purpose of the option: "Be quiet, only report errors."

2022-03-23pack-objects: parse --filter directly into revs.filterLibravatar Derrick Stolee1-6/+2
The previous change moved the 'revs' variable into cmd_pack_objects() and now we can remove the global filter_options in favor of revs.filter. Signed-off-by: Derrick Stolee <derrickstolee@github.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2022-03-23pack-objects: move revs out of get_object_list()Libravatar Derrick Stolee1-15/+18
We intend to parse the --filter option directly into revs.filter, but we first need to move the 'revs' variable out of get_object_list() and pass it as a pointer instead.
