2020-10-01format-patch: teach format.useAutoBase "whenAble" optionLibravatar Jacob Keller1-0/+22
The format.useAutoBase configuration option exists to allow users to enable '--base=auto' for format-patch by default. This can sometimes lead to poor workflow, due to unexpected failures when attempting to format an ancient patch: $ git format-patch -1 <an old commit> fatal: base commit shouldn't be in revision list This can be very confusing, as it is not necessarily immediately obvious that the user requested a --base (since this was in the configuration, not on the command line). We do want --base=auto to fail when it cannot provide a suitable base, as it would be equally confusing if a formatted patch did not include the base information when it was requested. Teach format.useAutoBase a new mode, "whenAble". This mode will cause format-patch to attempt to include a base commit when it can. However, if no valid base commit can be found, then format-patch will continue formatting the patch without a base commit. In order to avoid making yet another branch name unusable with --base, do not teach --base=whenAble or --base=whenable. Instead, refactor the base_commit option to use a callback, and rely on the global configuration variable auto_base. This does mean that a user cannot request this optional base commit generation from the command line. However, this is likely not too valuable. If the user requests base information manually, they will be immediately informed of the failure to acquire a suitable base commit. This allows the user to make an informed choice about whether to continue the format. Add tests to cover the new mode of operation for --base.

2020-09-19send-pack: run GPG after atomic push checkingLibravatar Han Xin1-0/+23
The refs update commands can be sent to the server side in two different ways: GPG-signed or unsigned. We should run these two operations in the same "Finally, tell the other end!" code block, but they are seperated by the "Clear the status for each ref" code block. This will result in a slight performance loss, because the failed atomic push will still perform unnecessary preparations for shallow advertise and GPG-signed commands buffers, and user may have to be bothered by the (possible) GPG passphrase input when there is nothing to sign. Add a new test case to t5534 to ensure GPG will not be called when the GPG-signed atomic push fails.

2020-09-17packfile: actually set approximate_object_count_validLibravatar Jeff King1-0/+4
The approximate_object_count() function tries to compute the count only once per process. But ever since it was introduced in 8e3f52d778 (find_unique_abbrev: move logic out of get_short_sha1(), 2016-10-03), we failed to actually set the "valid" flag, meaning we'd compute it fresh on every call. This turns out not to be _too_ bad, because we're only iterating through the packed_git list, and not making any system calls. But since it may get called for every abbreviated hash we output, even this can add up if you have many packs. Here are before-and-after timings for a new perf test which just asks rev-list to abbreviate each commit hash (the test repo is linux.git, with commit-graphs): Test origin HEAD ---------------------------------------------------------------------------- 5303.3: rev-list (1) 28.91(28.46+0.44) 29.03(28.65+0.38) +0.4% 5303.4: abbrev-commit (1) 1.18(1.06+0.11) 1.17(1.02+0.14) -0.8% 5303.7: rev-list (50) 28.95(28.56+0.38) 29.50(29.17+0.32) +1.9% 5303.8: abbrev-commit (50) 3.67(3.56+0.10) 3.57(3.42+0.15) -2.7% 5303.11: rev-list (1000) 30.34(29.89+0.43) 30.82(30.35+0.46) +1.6% 5303.12: abbrev-commit (1000) 86.82(86.52+0.29) 77.82(77.59+0.22) -10.4% 5303.15: load 10,000 packs 0.08(0.02+0.05) 0.08(0.02+0.06) +0.0% It doesn't help at all when we have 1 pack (5303.4), but we get a 10% speedup when there are 1000 packs (5303.12). That's a modest speedup for a case that's already slow and we'd hope to avoid in general (note how slow it is even after, because we have to look in each of those packs for abbreviations). But it's a one-line change that clearly matches the original intent, so it seems worth doing. The included perf test may also be useful for keeping an eye on any regressions in the overall abbreviation code.

2020-09-17maintenance: use pointers to check --autoLibravatar Derrick Stolee2-2/+2
The 'git maintenance run' command has an '--auto' option. This is used by other Git commands such as 'git commit' or 'git fetch' to check if maintenance should be run after adding data to the repository. Previously, this --auto option was only used to add the argument to the 'git gc' command as part of the 'gc' task. We will be expanding the other tasks to perform a check to see if they should do work as part of the --auto flag, when they are enabled by config. First, update the 'gc' task to perform the auto check inside the maintenance process. This prevents running an extra 'git gc --auto' command when not needed. It also shows a model for other tasks. Second, use the 'auto_condition' function pointer as a signal for whether we enable the maintenance task under '--auto'. For instance, we do not want to enable the 'fetch' task in '--auto' mode, so that function pointer will remain NULL. Now that we are not automatically calling 'git gc', a test in t5514-fetch-multiple.sh must be changed to watch for 'git maintenance' instead. We continue to pass the '--auto' option to the 'git gc' command when necessary, because of the gc.autoDetach config option changes behavior. Likely, we will want to absorb the daemonizing behavior implied by gc.autoDetach as a maintenance.autoDetach config option.

2020-09-17maintenance: create maintenance.<task>.enabled configLibravatar Derrick Stolee1-0/+8
Currently, a normal run of "git maintenance run" will only run the 'gc' task, as it is the only one enabled. This is mostly for backwards- compatible reasons since "git maintenance run --auto" commands replaced previous "git gc --auto" commands after some Git processes. Users could manually run specific maintenance tasks by calling "git maintenance run --task=<task>" directly. Allow users to customize which steps are run automatically using config. The 'maintenance.<task>.enabled' option then can turn on these other tasks (or turn off the 'gc' task).

2020-09-17maintenance: add --task optionLibravatar Derrick Stolee1-0/+27
A user may want to only run certain maintenance tasks in a certain order. Add the --task=<task> option, which allows a user to specify an ordered list of tasks to run. These cannot be run multiple times, however. Here is where our array of maintenance_task pointers becomes critical. We can sort the array of pointers based on the task order, but we do not want to move the struct data itself in order to preserve the hashmap references. We use the hashmap to match the --task=<task> arguments into the task struct data. Keep in mind that the 'enabled' member of the maintenance_task struct is a placeholder for a future 'maintenance.<task>.enabled' config option. Thus, we use the 'enabled' member to specify which tasks are run when the user does not specify any --task=<task> arguments. The 'enabled' member should be ignored if --task=<task> appears.

2020-09-17maintenance: add commit-graph taskLibravatar Derrick Stolee1-0/+2
The first new task in the 'git maintenance' builtin is the 'commit-graph' task. This updates the commit-graph file incrementally with the command git commit-graph write --reachable --split By writing an incremental commit-graph file using the "--split" option we minimize the disruption from this operation. The default behavior is to merge layers until the new "top" layer is less than half the size of the layer below. This provides quick writes most of the time, with the longer writes following a power law distribution. Most importantly, concurrent Git processes only look at the commit-graph-chain file for a very short amount of time, so they will verly likely not be holding a handle to the file when we try to replace it. (This only matters on Windows.) If a concurrent process reads the old commit-graph-chain file, but our job expires some of the .graph files before they can be read, then those processes will see a warning message (but not fail). This could be avoided by a future update to use the --expire-time argument when writing the commit-graph.

2020-09-17maintenance: replace run_auto_gc()Libravatar Derrick Stolee1-1/+1
The run_auto_gc() method is used in several places to trigger a check for repo maintenance after some Git commands, such as 'git commit' or 'git fetch'. To allow for extra customization of this maintenance activity, replace the 'git gc --auto [--quiet]' call with one to 'git maintenance run --auto [--quiet]'. As we extend the maintenance builtin with other steps, users will be able to select different maintenance activities. Rename run_auto_gc() to run_auto_maintenance() to be clearer what is happening on this call, and to expose all callers in the current diff. Rewrite the method to use a struct child_process to simplify the calls slightly. Since 'git fetch' already allows disabling the 'git gc --auto' subprocess, add an equivalent option with a different name to be more descriptive of the new behavior: '--[no-]maintenance'. Update the documentation to include these options at the same time. Signed-off-by: Derrick Stolee <dstolee@microsoft.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2020-09-17maintenance: create basic maintenance runnerLibravatar Derrick Stolee2-0/+56
The 'gc' builtin is our current entrypoint for automatically maintaining a repository. This one tool does many operations, such as repacking the repository, packing refs, and rewriting the commit-graph file. The name implies it performs "garbage collection" which means several different things, and some users may not want to use this operation that rewrites the entire object database. Create a new 'maintenance' builtin that will become a more general- purpose command. To start, it will only support the 'run' subcommand, but will later expand to add subcommands for scheduling maintenance in the background. For now, the 'maintenance' builtin is a thin shim over the 'gc' builtin. In fact, the only option is the '--auto' toggle, which is handed directly to the 'gc' builtin. The current change is isolated to this simple operation to prevent more interesting logic from being lost in all of the boilerplate of adding a new builtin. Use existing builtin/gc.c file because we want to share code between the two builtins. It is possible that we will have 'maintenance' replace the 'gc' builtin entirely at some point, leaving 'git gc' as an alias for some specific arguments to 'git maintenance run'. Create a new test_subcommand helper that allows us to test if a certain subcommand was run. It requires storing the GIT_TRACE2_EVENT logs in a file. A negation mode is available that will be used in later tests.

2020-09-09add -p: fix editing of intent-to-add pathsLibravatar Phillip Wood1-0/+38
A popular way of partially staging a new file is to run `git add -N <path>` and then use the hunk editing of `git add -p` to select the part of the file that the user wishes to stage. Since 85953a3187 ("diff-files --raw: show correct post-image of intent-to-add files", 2020-07-01) this has stopped working as intent-to-add paths are now show as new files rather than changes to an empty blob and `git apply` refused to apply a creation patch for a path that was marked as intent-to-add. 7cfde3fa0f ("apply: allow "new file" patches on i-t-a entries", 2020-08-06) fixed the problem with apply but it still wasn't possible to edit the added hunk properly. 2c8bd8471a ("checkout -p: handle new files correctly", 2020-05-27) had previously changed `add -p` to handle new files but it did not implement patch editing correctly. The perl version simply forbade editing and the C version opened the editor with the full diff rather that just the hunk which meant that the user had to edit the hunk header manually to get it to work. The root cause of the problem is that added files store the diff header with the hunk data rather than separating the two as we do for other changes. Changing added files to store the diff header separately fixes the editing problem at the expense of having to special case empty additions as they no longer have any hunks associated with them, only the diff header.

2020-09-08add--interactive.perl: specify --no-color explicitlyLibravatar Jeff King1-0/+1
Our color tests of "git add -p" do something a bit different from how a normal user would behave: we pretend there's a pager in use, so that Git thinks it's OK to write color to a non-tty stdout. This comes from 8539b46534 (t3701: avoid depending on the TTY prerequisite, 2019-12-06), which allows us to avoid a lot of complicated mock-tty code. However, those environment variables also make their way down to sub-processes of add--interactive, including the "diff-files" we run to generate the patches. As a result, it thinks it should output color, too. So in t3701.50, for example, the machine-readable version of the diff we get unexpectedly has color in it. We fail to parse it as a diff and think there are zero hunks. The test does still pass, though, because even with zero hunks we'll dump the diff header (and we consider those unparseable bits to be part of the header!), and so the output still has the expected color codes in it. We don't notice that the command was totally broken and failed to apply anything. And in fact we're not really testing what we think we are about the color, either. While add--interactive does correctly show the version we got from running "diff-files --color", we'd also pass the test if we had accidentally shown the machine-readable version, too, since it (erroneously) has color codes in it. One could argue that the test isn't very realistic; it's setting up this "pretend there's a pager" situation to get around the tty restrictions of the test environment. So one option would be to move back towards using a real tty. But the behavior of add--interactive really is user-visible here. If a user, for whatever reason, did run "git --paginate add --patch" (perhaps because their pager is really a filter or something), the command would totally fail to do anything useful. Since we know that we don't want color in this output, let's just make add--interactive more defensive, and say "--no-color" explicitly. It doesn't hurt anything in the common case, but it fixes this odd case and lets our test function properly again. Note that the C builtin run_add_p() already passes --no-color, so it doesn't need a similar fix. That will eventually replace this perl code anyway, but the test change here will be valuable for ensuring that.

2020-09-08add-patch: fix inverted return code of repo_read_index()Libravatar Jeff King1-0/+7
After applying hunks to a file with "add -p", the C patch_update_file() function tries to refresh the index (just like the perl version does). We can only refresh the index if we're able to read it in, so we first check the return value of repo_read_index(). But unlike many functions, where "0" is success, that function is documented to return the number of entries in the index. Hence we should be checking for success with a non-negative return value. Neither the tests nor any users seem to have noticed this, probably due to a combination of: - this affects only the C version, which is not yet the default - following it up with any porcelain command like "git diff" or "git commit" would refresh the index automatically. But you can see the problem by running the plumbing "git diff-files" immediately after "add -p" stages all hunks. Running the new test with GIT_TEST_ADD_I_USE_BUILTIN=1 fails without the matching code change.

2020-09-02wt-status: tolerate dangling marksLibravatar Jonathan Tan1-0/+12
When a user checks out the upstream branch of HEAD, the upstream branch not being a local branch, and then runs "git status", like this: git clone $URL client cd client git checkout @{u} git status no status is printed, but instead an error message: fatal: HEAD does not point to a branch (This error message when running "git branch" persists even after checking out other things - it only stops after checking out a branch.) This is because "git status" reads the reflog when determining the "HEAD detached" message, and thus attempts to DWIM "@{u}", but that doesn't work because HEAD no longer points to a branch. Therefore, when calculating the status of a worktree, tolerate dangling marks. This is done by adding an additional parameter to dwim_ref() and repo_dwim_ref().

2020-09-02fetch: no FETCH_HEAD display if --no-write-fetch-headLibravatar Jonathan Tan2-10/+15
887952b8c6 ("fetch: optionally allow disabling FETCH_HEAD update", 2020-08-18) introduced the ability to disable writing to FETCH_HEAD during fetch, but did not suppress the "<source> -> FETCH_HEAD" message when this ability is used. This message is misleading in this case, because FETCH_HEAD is not written. Also, because "fetch" is used to lazy-fetch missing objects in a partial clone, this significantly clutters up the output in that case since the objects to be fetched are potentially numerous. Therefore, suppress this message when --no-write-fetch-head is passed (but not when --dry-run is set).
