2021-12-30sparse-checkout: refuse to add to bad patternsLibravatar Derrick Stolee1-0/+3
When in cone mode sparse-checkout, it is unclear how 'git sparse-checkout add <dir1> ...' should behave if the existing sparse-checkout file does not match the cone mode patterns. Change the behavior to fail with an error message about the existing patterns. Also, all cone mode patterns start with a '/' character, so add that restriction. This is necessary for our example test 'cone mode: warn on bad pattern', but also requires modifying the example sparse-checkout file we use to test the warnings related to recognizing cone mode patterns. This error checking would cause a failure further down the test script because of a test that adds non-cone mode patterns without cleaning them up. Perform that cleanup as part of the test now.

Add a test to t1091-sparse-checkout-builtin.sh that would result in an infinite loop and out-of-memory error before this change. The issue relies on having non-cone-mode patterns while trying to modify the patterns in cone-mode. The fix is simple, allowing us to break from the loop when the input path does not contain a slash, as the "dir" pattern we added does not. This is only a fix to the critical out-of-memory error. A better response to such a strange state will follow in a later change.

2021-12-22reflog + refs-backend: move "verbose" out of the backendLibravatar Ævar Arnfjörð Bjarmason1-9/+47
Move the handling of the "verbose" flag entirely out of "refs/files-backend.c" and into "builtin/reflog.c". This allows the backend to stop knowing about the EXPIRE_REFLOGS_VERBOSE flag. The expire_reflog_ent() function shouldn't need to deal with the implementation detail of whether or not we're emitting verbose output, by doing this the --verbose output becomes backend-agnostic, so reftable will get the same output. I think the output is rather bad currently, and should e.g. be implemented with some better future mode of progress.[ch], but that's a topic for another improvement.

2021-12-22reflog expire: don't use lookup_commit_reference_gently()Libravatar Ævar Arnfjörð Bjarmason1-2/+1
In the initial implementation of "git reflog" in 4264dc15e19 (git reflog expire, 2006-12-19) we had this lookup_commit_reference_gently(). I don't think we've ever found tags that we need to recursively dereference in reflogs, so this should at least be changed to a "lookup commit" as I'm doing here, although I can't think of a way where it mattered in practice. I also think we'd probably like to just die here if we have a NULL object, but as this code needs to handle potentially broken repositories let's just show an "error" but continue, the non-quiet lookup_commit() will do for us.

Now we won't assume that "x != UE_ALWAYS" means "(x == UE_HEAD || x || UE_NORMAL)".

This does not change any behavior, allows us to delete much of this code as it's replaced by things we get from the string-list API for free, as a result we need just one struct to keep track of this data, instead of two.

As with the preceding change for "reflog delete", change the "cb_data" we pass to callbacks to be &cb.cmd itself, instead of passing &cb and having the callback lookup cb->cmd. This makes it clear that the "cb" itself is the same memzero'd structure on each iteration of the for-loops that use &cb, except for the "cmd" member. The "struct expire_reflog_policy_cb" we pass to reflog_expire() will have the members that aren't "cmd" modified by the callbacks, but before we invoke them everything except "cmd" is zero'd out. This included the "tip_commit", "mark_list" and "tips". It might have looked as though we were re-using those between iterations, but the first thing we did in reflog_expiry_prepare() was to either NULL them, or clobber them with another value.

2021-12-22ls-files: add --sparse optionLibravatar Derrick Stolee1-2/+10
Existing callers to 'git ls-files' are expecting file names, not directories. It is best to expand a sparse index to show all of the contained files in this case. However, expert users may want to inspect the contents of the index itself including which directories are sparse. Add a --sparse option to allow users to request this information. During testing, I noticed that options such as --modified did not affect the output when the files in question were outside the sparse-checkout definition. Tests are added to document this preexisting behavior and how it remains unchanged with the sparse index and the --sparse option.

2021-12-22fetch/pull: use the sparse indexLibravatar Derrick Stolee2-0/+4
The 'git fetch' and 'git pull' commands parse the index in order to determine if submodules exist. Without command_requires_full_index=0, this will expand a sparse index, causing slow performance even when there is no new data to fetch. The .gitmodules file will never be inside a sparse directory entry, and even if it was, the index_name_pos() method would expand the sparse index if needed as we search for the path by name. These commands do not iterate over the index, which is the typical thing we are careful about when integrating with the sparse index.

2021-12-21fast-export: fix surprising behavior with --first-parentLibravatar William Sprent1-36/+4
The revision traversal machinery typically processes and returns all children before any parent. fast-export needs to operate in the reverse fashion, handling parents before any of their children in order to build up the history starting from the root commit(s). This would be a clear case where we could just use the revision traversal machinery's "reverse" option to achieve this desired affect. However, this wasn't what the code did. It added its own array for queuing. The obvious hand-rolled solution would be to just push all the commits into the array and then traverse afterwards, but it didn't quite do that either. It instead attempted to process anything it could as soon as it could, and once it could, check whether it could process anything that had been queued. As far as I can tell, this was an effort to save a little memory in the case of multiple root commits since it could process some commits before queueing all of them. This involved some helper functions named has_unshown_parent() and handle_tail(). For typical invocations of fast-export, this alternative essentially amounted to a hand-rolled method of reversing the commits -- it was a bunch of work to duplicate the revision traversal machinery's "reverse" option. This hand-rolled reversing mechanism is actually somewhat difficult to reason about. It takes some time to figure out how it ensures in normal cases that it will actually process all traversed commits (rather than just dropping some and not printing anything for them). And it turns out there are some cases where the code does drop commits without handling them, and not even printing an error or warning for the user. Due to the has_unshown_parent() checks, some commits could be left in the array at the end of the "while...get_revision()" loop which would be unprocessed. This could be triggered for example with git fast-export main -- --first-parent or non-sensical traversal rules such as git fast-export main -- --grep=Merge --invert-grep While most traversals that don't include all parents should likely trigger errors in fast-export (or at least require being used in combination with --reference-excluded-parents), the --first-parent traversal is at least reasonable and it'd be nice if it didn't just drop commits. It'd also be nice for future readers of the code to have a simpler "reverse traversal" mechanism. Use the "reverse" option of the revision traversal machinery to achieve both. Even for the non-sensical traversal flags like the --grep one above, this would be an improvement. For example, in that case, the code previously would have silently truncated history to only those commits that do not have an ancestor containing "Merge" in their commit message. After this code change, that case would include all commits without "Merge" in their commit message -- but any commit that previously had a "Merge"-mentioning parent would lose that parent (likely resulting in many new root commits). While the new behavior is still odd, it is at least understandable given that --reference-excluded-parents is not the default.

2021-12-20branch: add flags and config to inherit trackingLibravatar Josh Steadmon2-4/+8
It can be helpful when creating a new branch to use the existing tracking configuration from the branch point. However, there is currently not a method to automatically do so. Teach git-{branch,checkout,switch} an "inherit" argument to the "--track" option. When this is set, creating a new branch will cause the tracking configuration to default to the configuration of the branch point, if set. For example, if branch "main" tracks "origin/main", and we run `git checkout --track=inherit -b feature main`, then branch "feature" will track "origin/main". Thus, `git status` will show us how far ahead/behind we are from origin, and `git pull` will pull from origin. This is particularly useful when creating branches across many submodules, such as with `git submodule foreach ...` (or if running with a patch such as [1], which we use at $job), as it avoids having to manually set tracking info for each submodule. Since we've added an argument to "--track", also add "--track=direct" as another way to explicitly get the original "--track" behavior ("--track" without an argument still works as well). Finally, teach branch.autoSetupMerge a new "inherit" option. When this is set, "--track=inherit" becomes the default behavior.

2021-12-20merge: allow to pretend a merge is made into a different branchLibravatar Junio C Hamano2-0/+8
When a series of patches for a topic-B depends on having topic-A, the workflow to prepare the topic-B branch would look like this: $ git checkout -b topic-B main $ git merge --no-ff --no-edit topic-A $ git am <mbox-for-topic-B When topic-A gets updated, recreating the first merge and rebasing the rest of the topic-B, all on detached HEAD, is a useful technique. After updating topic-A with its new round of patches: $ git checkout topic-B $ prev=$(git rev-parse 'HEAD^{/^Merge branch .topic-A. into}') $ git checkout --detach $prev^1 $ git merge --no-ff --no-edit topic-A $ git rebase --onto HEAD $prev @{-1}^0 $ git checkout -B @{-1} This will (0) check out the current topic-B. (1) find the previous merge of topic-A into topic-B. (2) detach the HEAD to the parent of the previous merge. (3) merge the updated topic-A to it. (4) reapply the patches to rebuild the rest of topic-B. (5) update topic-B with the result. without contaminating the reflog of topic-B too much. topic-B@{1} is the "logically previous" state before topic-A got updated, for example. At (4), comparison (e.g. range-diff) between HEAD and @{-1} is a meaningful way to sanity check the result, and the same can be done at (5) by comparing topic-B and topic-B@{1}. But there is one glitch. The merge into the detached HEAD done in the step (3) above gives us "Merge branch 'topic-A' into HEAD", and does not say "into topic-B". Teach the "--into-name=<branch>" option to "git merge" and its underlying "git fmt-merge-message", to pretend as if we were merging into <branch>, no matter what branch we are actually merging into, when they prepare the merge message. The pretend name honors the usual "into <target>" suppression mechanism, which can be seen in the tests added here. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2021-12-20repack: make '--quiet' disable progressLibravatar Derrick Stolee1-2/+4
While testing some ideas in 'git repack', I ran it with '--quiet' and discovered that some progress output was still shown. Specifically, the output for writing the multi-pack-index showed the progress. The 'show_progress' variable in cmd_repack() is initialized with isatty(2) and is not modified at all by the '--quiet' flag. The '--quiet' flag modifies the po_args.quiet option which is translated into a '--quiet' flag for the 'git pack-objects' child process. However, 'show_progress' is used to directly send progress information to the multi-pack-index writing logic which does not use a child process. The fix here is to modify 'show_progress' to be false if po_opts.quiet is true, and isatty(2) otherwise. This new expectation simplifies a later condition that checks both. Update the documentation to make it clear that '-q' will disable all progress in addition to ensuring the 'git pack-objects' child process will receive the flag. Use 'test_terminal' to check that this works to get around the isatty(2) check.

2021-12-20repack: respect kept objects with '--write-midx -b'Libravatar Derrick Stolee1-1/+1
Historically, we needed a single packfile in order to have reachability bitmaps. This introduced logic that when 'git repack' had a '-b' option that we should stop sending the '--honor-pack-keep' option to the 'git pack-objects' child process, ensuring that we create a packfile containing all reachable objects. In the world of multi-pack-index bitmaps, we no longer need to repack all objects into a single pack to have valid bitmaps. Thus, we should continue sending the '--honor-pack-keep' flag to 'git pack-objects'. The fix is very simple: only disable the flag when writing bitmaps but also _not_ writing the multi-pack-index. This opens the door to new repacking strategies that might want to keep some historical set of objects in a stable pack-file while only repacking more recent objects. To test, create a new 'test_subcommand_inexact' helper that is more flexible than 'test_subcommand'. This allows us to look for the --honor-pack-keep flag without over-indexing on the exact set of arguments.

We do not do this at lower level in revision.c or cmd_log_walk(), as a new caller of the revision traversal API can make unbounded number of rev_info during a single run, and UNLEAK() would not a be suitable mechanism to deal with such a caller.

2021-12-16stash: don't show "git stash push" usage on bad "git stash" usageLibravatar Ævar Arnfjörð Bjarmason1-0/+1
Change the usage message emitted by "git stash --invalid-option" to emit usage information for "git stash" in general, and not just for the "push" command. I.e. before: $ git stash --invalid-option error: unknown option `invalid-option' usage: git stash [push [-p|--patch] [-k|--[no-]keep-index] [-q|--quiet] [-u|--include-untracked] [-a|--all] [-m|--message <message>] [--] [<pathspec>...]] [...] After: $ git stash --invalid-option error: unknown option `invalid-option' usage: git stash list [<options>] or: git stash show [<options>] [<stash>] or: git stash drop [-q|--quiet] [<stash>] or: git stash ( pop | apply ) [--index] [-q|--quiet] [<stash>] or: git stash branch <branchname> [<stash>] or: git stash clear or: git stash [push [-p|--patch] [-S|--staged] [-k|--[no-]keep-index] [-q|--quiet] [-u|--include-untracked] [-a|--all] [-m|--message <message>] [--pathspec-from-file=<file> [--pathspec-file-nul]] [--] [<pathspec>...]] or: git stash save [-p|--patch] [-S|--staged] [-k|--[no-]keep-index] [-q|--quiet] [-u|--include-untracked] [-a|--all] [<message>] [...] That we emitted the usage for just "push" in the case of the subcommand not being explicitly specified was an unintentional side-effect of how it was implemented. When it was converted to C in d553f538b8a (stash: convert push to builtin, 2019-02-25) the pattern of having per-subcommand usage information was rightly continued. The "git-stash.sh" shellscript did not have that, and always printed the equivalent of "git_stash_usage". But in doing so the case of push being implicit and explicit was conflated. A variable was added to track this in 8c3713cede7 (stash: eliminate crude option parsing, 2020-02-17), but it did not update the usage output accordingly. This still leaves e.g. "git stash push -h" emitting the "git_stash_usage" output, instead of "git_stash_push_usage". That should be fixed, but is a much deeper misbehavior in parse_options() not being aware of subcommands at all. I.e. in how PARSE_OPT_KEEP_UNKNOWN and PARSE_OPT_NO_INTERNAL_HELP combine in commands such as "git stash". Perhaps PARSE_OPT_KEEP_UNKNOWN should imply PARSE_OPT_NO_INTERNAL_HELP, or better yet parse_options() should be extended to fully handle these subcommand cases that we handle manually in "git stash", "git commit-graph", "git multi-pack-index" etc. All of those musings would be a much bigger change than this isolated fix though, so let's leave that for some other time.

2021-12-15am: support --allow-empty to record specific empty patchesLibravatar 徐沛文 (Aleen)1-8/+24
This option helps to record specific empty patches in the middle of an am session, which does create empty commits only when: 1. the index has not changed 2. lacking a branch When the index has changed, "--allow-empty" will create a non-empty commit like passing "--continue" or "--resolved".

2021-12-15am: support --empty=<option> to handle empty patchesLibravatar 徐沛文 (Aleen)1-5/+52
Since that the command 'git-format-patch' can include patches of commits that emit no changes, the 'git-am' command should also support an option, named as '--empty', to specify how to handle those empty patches. In this commit, we have implemented three valid options ('stop', 'drop' and 'keep'). Signed-off-by: 徐沛文 (Aleen) <aleen42@vip.qq.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2021-12-15sparse-checkout: enable `set` to initialize sparse-checkout modeLibravatar Elijah Newren1-1/+26
The previously suggested workflow: git sparse-checkout init ... git sparse-checkout set ... Suffered from three problems: 1) It would delete nearly all files in the first step, then restore them in the second. That was poor performance and forced unnecessary rebuilds. 2) The two-step process resulted in two progress bars, which was suboptimal from a UI point of view for wrappers that invoked both of these commands but only exposed a single command to their end users. 3) With cone mode, the first step would delete nearly all ignored files everywhere, because everything was considered to be outside of the specified sparsity paths. (The user was not allowed to specify any sparsity paths in the `init` step.) Avoid these problems by teaching `set` to understand the extra parameters that `init` takes and performing any necessary initialization if not already in a sparse checkout.

2021-12-15sparse-checkout: split out code for tweaking settings configLibravatar Elijah Newren1-19/+37
`init` has some code for handling updates to either cone mode or the sparse-index setting. We would like to be able to reuse this elsewhere, namely in `set` and `reapply`. Split this function out, and make it slightly more general so it can handle being called from the new callers.

2021-12-15sparse-checkout: add sanity-checks on initial sparsity stateLibravatar Elijah Newren1-0/+20
Most sparse-checkout subcommands (list, add, reapply) only make sense when already in a sparse state. Add a quick check that will error out early if this is not the case.

2021-12-15sparse-checkout: break apart functions for sparse_checkout_(set|add)Libravatar Elijah Newren1-14/+40
sparse_checkout_set() was reused by sparse_checkout_add() with the only difference being a single parameter being passed to that function. However, we would like sparse_checkout_set() to do the same work that sparse_checkout_init() does if sparse checkouts are not already enabled. To facilitate this transition, give each mode their own copy of the function. This does not introduce any behavioral changes; that will come in a subsequent patch.

add_patterns_from_input() has relied on a global variable, set_opts.use_stdin, which has been used by both the `set` and `add` subcommands of sparse-checkout. Once we introduce an add_opts.use_stdin, the hardcoding of set_opts.use_stdin will be incorrect. Pass the value as function parameter instead to allow us to make subsequent changes.
