2022-02-03progress API: unify stop_progress{,_msg}(), fix trace2 bugÆvar Arnfjörð Bjarmason3-20/+13
Fix a bug that's been with us ever since 98a13647408 (trace2: log progress time and throughput, 2020-05-12), when the stop_progress_msg() API was used we didn't log a "region_leave" for the "region_enter" we start in "start_progress_delay()". The only user of the "stop_progress_msg()" function is "index-pack". Let's add a previously failing test to check that we have the same number of "region_enter" and "region_leave" events, with "-v" we'll log progress even in the test environment. In addition to that we've had a submarine bug here introduced with 9d81ecb52b5 (progress: add sparse mode to force 100% complete message, 2019-03-21). The "start_sparse_progress()" API would only do the right thing if the progress was ended with "stop_progress()", not "stop_progress_msg()". The only user of that API uses "stop_progress()", but let's still fix that along with the trace2 issue by making "stop_progress()" a trivial wrapper for "stop_progress_msg()". We can also drop the "if (progress)" test from "finish_if_sparse()". It's now a helper for the small "stop_progress_msg()" function. We'll already have returned from it if "progress" is "NULL".

2022-02-03progress.c: refactor stop_progress{,_msg}() to use helpersÆvar Arnfjörð Bjarmason1-27/+35
Create two new static helpers for the stop_progress() and stop_progress_msg() functions. As we'll see in the subsequent commit having those two split up doesn't make much sense, and results in a bug in how we log to trace2. This narrow preparatory change makes the diff for that subsequent change smaller. Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2022-02-03progress.c: use dereferenced "progress" variable, not "(*p_progress)"Ævar Arnfjörð Bjarmason1-6/+9
Since 98a13647408 (trace2: log progress time and throughput, 2020-05-12) stop_progress() dereferences a "struct progress **" parameter in several places. Extract a dereferenced variable to reduce clutter and make it clearer who needs to write to this parameter. Now instead of using "*p_progress" several times in stop_progress() we check it once for NULL and then use a dereferenced "progress" variable thereafter. This uses the same pattern as the adjacent stop_progress_msg() function, see ac900fddb7f (progress: don't dereference before checking for NULL, 2020-08-10).

Fix an inconsistency introduced in dc6a0757c4f (make struct progress an opaque type, 2007-10-30) and rename the "progress" parameters to stop_progress{,_msg}() to "p_progress". Now these match the corresponding parameters in the *.c code. While we're at it let's move the definition of the former below the latter, a subsequent change will start defining stop_progress() in terms of stop_progress_msg().

2022-02-03progress.c tests: test some invalid usageÆvar Arnfjörð Bjarmason1-0/+50
Test what happens when we "stop" without a "start", omit the "stop" after a "start", or start two concurrent progress bars. This extends the trace2 tests added in 98a13647408 (trace2: log progress time and throughput, 2020-05-12). These tests are not merely testing the helper, but invalid API usage that can happen if the progress.c API is misused. The "without stop" test will leak under SANITIZE=leak, since this buggy use of the API will leak memory. But let's not skip it entirely, or use the "!SANITIZE_LEAK" prerequisite check as we'd do with tests that we're skipping due to leaks we haven't fixed yet. Instead annotate the specific command that should skip leak checking with custom $LSAN_OPTIONS[1]. 1. https://github.com/google/sanitizers/wiki/AddressSanitizerLeakSanitizer Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2022-02-02completion: add a GIT_COMPLETION_SHOW_ALL_COMMANDSÆvar Arnfjörð Bjarmason2-1/+43
Add a GIT_COMPLETION_SHOW_ALL_COMMANDS=1 configuration setting to go with the existing GIT_COMPLETION_SHOW_ALL=1 added in c099f579b98 (completion: add GIT_COMPLETION_SHOW_ALL env var, 2020-08-19). This will include plumbing commands such as "cat-file" in "git <TAB>" and "git c<TAB>" completion. Without/with this I have 134 and 243 completion with git <TAB>, respectively. It was already possible to do this by tweaking GIT_TESTING_PORCELAIN_COMMAND_LIST= from the outside, that testing variable was added in 84a97131065 (completion: let git provide the completable command list, 2018-05-20). Doing this before loading git-completion.bash worked: export GIT_TESTING_PORCELAIN_COMMAND_LIST="$(git --list-cmds=builtins,main,list-mainporcelain,others,nohelpers,alias,list-complete,config)" But such testing variables are not meant to be used from the outside, and we make no guarantees that those internal won't change. So let's expose this as a dedicated configuration knob. It would be better to teach --list-cmds=* a new category which would include all of these groups, but that's a larger change that we can leave for some other time. 1. https://lore.kernel.org/git/CAGP6POJ9gwp+t-eP3TPkivBLLbNb2+qj=61Mehcj=1BgrVOSLA@mail.gmail.com/ Reported-by: Hongyi Zhao <hongyi.zhao@gmail.com> Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2022-02-02completion tests: re-source git-completion.bash in a subshellÆvar Arnfjörð Bjarmason1-21/+29
Change tests of git-completion.bash that re-source it to do so inside a subshell. Re-sourcing it will clobber variables it sets, and in the case of the "GIT_COMPLETION_SHOW_ALL=1" test added in ca2d62b7879 (parse-options: don't complete option aliases by default, 2021-07-16) change the behavior of the completion persistently. Aside from the addition of "(" and ")" on new lines this is an indentation-only change, only the "(" and ")" lines are changed under "git diff -w". So let's change that test, and for good measure do the same for the three tests that precede it, which were added in 8b0eaa41f23 (completion: clear cached --options when sourcing the completion script, 2018-03-22).

2022-02-02patch-id: fix scan_hunk_header on diffs with 1 line of before/afterJerry Zhang2-3/+37
Normally diffs will contain a hunk header of the format "@@ -2,2 +2,15 @@ code". However when there is only 1 line of change, the unified diff format allows for the second comma separated value to be omitted in either before or after line counts. This can produce hunk headers that look like "@@ -2 +2,18 @@ code" or "@@ -2,2 +2 @@ code". As a result, scan_hunk_header mistakenly returns the line number as line count, which then results in unpredictable parsing errors with the rest of the patch, including giving multiple lines of output for a single commit. Fix by explicitly setting line count to 1 when there is no comma, and add a test. apply.c contains this same logic except it is correct. A worthwhile future project might be to unify these two diff parsers so they both benefit from fixes. Signed-off-by: Jerry Zhang <jerry@skydio.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2022-02-02diff-merges: avoid history simplifications when diffing mergesElijah Newren2-1/+59
Doing diffs for merges are special; they should typically avoid history simplification. For example, with git log --diff-merges=first-parent -- path the default history simplification would remove merge commits from consideration if the file "path" matched the second parent. That is counter to what the user wants when looking for first-parent diffs. Similar comments can be made for --diff-merges=separate (which diffs against both parents) and --diff-merges=remerge (which diffs against a remerge of the merge commit). However, history simplification still makes sense if not doing diffing merges, and it also makes sense for the combined and dense-combined forms of diffing merges (because both of those are defined to only show a diff when the merge result at the relevant paths differs from *both* parents). So, for separate, first-parent, and remerge styles of diff-merges, turn off history simplification. Signed-off-by: Elijah Newren <newren@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2022-02-02merge-ort: mark conflict/warning messages from inner merges as omittableElijah Newren1-1/+3
A recursive merge involves merging the merge bases of the two branches being merged. Such an inner merge can itself generate conflict notices.

2022-02-02merge-ort: mark a few more conflict messages as omittableElijah Newren1-2/+2
path_msg() has the ability to mark messages as omittable, designed for remerge-diff where we'll instead be showing conflict messages as diff headers for a subsequent diff. While all these messages are very useful when trying to create a merge initially, early use with the --remerge-diff feature (the only user of this omittable conflict message capability), suggests that the particular messages marked in this commit are just noise when trying to see what changes users made to create a merge commit. Mark them as omittable. Note that there were already a few messages marked as omittable in merge-ort when doing a remerge-diff, because the development of --remerge-diff preceded the upstreaming of merge-ort and I was trying to ensure merge-ort could handle all the necessary requirements. See commit c5a6f65527 ("merge-ort: add modify/delete handling and delayed output processing", 2020-12-03) for the initial details. For some examples of already-marked-as-omittable messages, see either "Auto-merging <path>" or some of the submodule update hints. This commit just adds two more messages that should also be omittable. Signed-off-by: Elijah Newren <newren@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2022-02-02merge-ort: capture and print ll-merge warnings in our preferred fashionElijah Newren3-6/+17
Instead of immediately printing ll-merge warnings to stderr, we save them in our output strbuf. Besides allowing us to move these warnings to a special file for --remerge-diff, this has two other benefits for regular merges done by merge-ort: * The deferral of messages ensures we can print all messages about any given path together (merge-recursive was known to sometimes intersperse messages about other paths, particularly when renames were involved). * The deferral of messages means we can avoid printing spurious conflict messages when we just end up aborting due to local user modifications in the way. (In contrast to merge-recursive.c which prematurely checks for local modifications in the way via unpack_trees() and gets the check wrong both in terms of false positives and false negatives relative to renames, merge-ort does not perform the local modifications in the way check until the checkout() step after the full merge has been computed.)

2022-02-02ll-merge: make callers responsible for showing warningsElijah Newren9-32/+63
Since some callers may want to send warning messages to somewhere other than stdout/stderr, stop printing "warning: Cannot merge binary files" from ll-merge and instead modify the return status of ll_merge() to indicate when a merge of binary files has occurred. Message printing probably does not belong in a "low-level merge" anyway. This commit continues printing the message as-is, just from the callers instead of within ll_merge(). Future changes will start handling the message differently in the merge-ort codepath. There was one special case here: the callers in rerere.c do NOT check for and print such a message; since those code paths explicitly skip over binary files, there is no reason to check for a return status of LL_MERGE_BINARY_CONFLICT or print the related message. Note that my methodology included first modifying ll_merge() to return a struct, so that the compiler would catch all the callers for me and ensure I had modified all of them. After modifying all of them, I then changed the struct to an enum. Signed-off-by: Elijah Newren <newren@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2022-02-02log: clean unneeded objects during `log --remerge-diff`Elijah Newren5-7/+28
The --remerge-diff option will need to create new blobs and trees representing the "automatic merge" state. If one is traversing a long project history, one can easily get hundreds of thousands of loose objects generated during `log --remerge-diff`. However, none of those loose objects are needed after we have completed our diff operation; they can be summarily deleted. Add a new helper function to tmp_objdir to discard all the contained objects, and call it after each merge is handled.

2022-02-02show, log: provide a --remerge-diff capabilityElijah Newren6-2/+191
When this option is specified, we remerge all (two parent) merge commits and diff the actual merge commit to the automatically created version, in order to show how users removed conflict markers, resolved the different conflict versions, and potentially added new changes outside of conflict regions in order to resolve semantic merge problems (or, possibly, just to hide other random changes). This capability works by creating a temporary object directory and marking it as the primary object store. This makes it so that any blobs or trees created during the automatic merge are easily removable afterwards by just deleting all objects from the temporary object directory. There are a few ways that this implementation is suboptimal: * `log --remerge-diff` becomes slow, because the temporary object directory can fill with many loose objects while running * the log output can be muddied with misplaced "warning: cannot merge binary files" messages, since ll-merge.c unconditionally writes those messages to stderr while running instead of allowing callers to manage them. * important conflict and warning messages are simply dropped; thus for conflicts like modify/delete or rename/rename or file/directory which are not representable with content conflict markers, there may be no way for a user of --remerge-diff to know that there had been a conflict which was resolved (and which possibly motivated other changes in the merge commit). * when fixing the previous issue, note that some unimportant conflict and warning messages might start being included. We should instead make sure these remain dropped. Subsequent commits will address these issues. Signed-off-by: Elijah Newren <newren@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

In commit 3050b6dfc75d (repo-settings.c: simplify the setup, 2021-09-21), the branch for handling fetch.negotiationAlgorithm=default was deleted. Since this value is documented in Documentation/config/fetch.txt, restore the check for this value. Note that this change caused an observable bug: if someone sets feature.experimental=true in config, and then passes "-c fetch.negotiationAlgorithm=default" on the command line in an attempt to override the config, then the override is ignored. Fix the bug by not ignoring the value of "default". Technically, before commit 3050b6dfc75d, repo-settings would treat any fetch.negotiationAlgorithm value other than "skipping" or "noop" as a request for "default", but I think it probably makes more sense to ignore such broken requests and leave fetch.negotiationAlgorithm with the default value rather than the value of "default". (If that sounds confusing, note that "default" is usually the default value, but when feature.experimental=true, "skipping" is the default value.)

2022-02-01perl Git.pm: don't ignore signalled failure in _cmd_close()Ævar Arnfjörð Bjarmason5-6/+19
Fix misbehavior in Git.pm that dates back to the very first version of the library in git.git added in b1edc53d062 (Introduce Git.pm (v4), 2006-06-24). When we fail to execute a command we shouldn't ignore all signals, those can happen e.g. if abort() is called, or if the command segfaults. Because of this we'd consider e.g. a command that died due to LSAN exiting with abort() successful, as is the case with the tests listed as running successfully with SANITIZE=leak in 9081a421a6d (checkout: fix "branch info" memory leaks, 2021-11-16). We did run them successfully, but only because we ignored these errors. This was then made worse by the use of "abort_on_error=1" for LSAN added in 85b81b35ff9 (test-lib: set LSAN_OPTIONS to abort by default, 2017-09-05). Doing that makes sense, but without providing that option we'd have a "$? >> 8" of "23" on failure, with abort_on_error=1 we'll get "0". All of our tests pass even without the SIGPIPE exception being added here, but as the code appears to have been trying to ignore it let's keep ignoring it for now.

2022-02-01receive-pack: purge temporary data if no command is ready to runChen Bojun2-0/+17
When pushing a hidden ref, e.g.: $ git push origin HEAD:refs/hidden/foo "receive-pack" will reject our request with an error message like this: ! [remote rejected] HEAD -> refs/hidden/foo (deny updating a hidden ref) The remote side ("git-receive-pack") will not create the hidden ref as expected, but the pack file sent by "git-send-pack" is left inside the remote repository. I.e. the quarantine directory is not purged as it should be. Add a checkpoint before calling "tmp_objdir_migrate()" and after calling the "pre-receive" hook to purge that temporary data in the quarantine area when there is no command ready to run. The reason we do not add the checkpoint before the "pre-receive" hook, but after it, is that the "pre-receive" hook is called with a switch-off "skip_broken" flag, and all commands, even broken ones, should be fed by calling "feed_receive_hook()".

2022-02-01branch: move --set-upstream-to behavior to dwim_and_setup_tracking()Glen Choo3-26/+92
This commit is preparation for a future commit that will simplify create_branch() so that it always creates a branch. This will allow create_branch() to accept a dry_run parameter (which is needed for "git branch --recurse-submodules"). create_branch() used to always create a branch, but 4fc5006676 (Add branch --set-upstream, 2010-01-18) changed it to also be able to set tracking information without creating a branch. Refactor the code that sets tracking information into its own functions dwim_branch_start() and dwim_and_setup_tracking(). Also change an invocation of create_branch() in cmd_branch() in builtin/branch.c to use dwim_and_setup_tracking(), since that invocation is only for setting tracking information (in "git branch --set-upstream-to"). As of this commit, create_branch() is no longer invoked in a way that does not create branches.

2022-02-01subtree: force merge commitThomas Koutcher1-2/+2
When `merge.ff` is set to `only` in .gitconfig, `git subtree pull` will fail with error `fatal: Not possible to fast-forward, aborting.`, but the command does want to make merges in these places. Add `--no-ff` argument to `git merge` to enforce this behaviour.

2022-01-31fetch --prune: exit with error if pruning failsThomas Gummerer2-4/+17
When pruning refs fails, we print an error to stderr, but still exit 0 from 'git fetch'. Since this is a genuine error, fetch should be exiting with some non-zero exit code. Make it so. The --prune option was introduced in f360d844de ("builtin-fetch: add --prune option", 2009-11-10). Unfortunately it's unclear from that commit whether ignoring the exit code was an oversight or intentional, but it feels like an oversight.

2022-01-28scalar: accept -C and -c options before the subcommandJohannes Schindelin3-1/+39
The `git` executable has these two very useful options: -C <directory>: switch to the specified directory before performing any actions -c <key>=<value>: temporarily configure this setting for the duration of the specified scalar subcommand With this commit, we teach the `scalar` executable the same trick. Note: It might look like a good idea to try to reuse the `handle_options()` function in `git.c` instead of replicating only the `-c`/`-C` part. However, that function is not only not in `libgit.a`, it is also intricately entangled with the rest of the code in `git.c` that is necessary e.g. to handle `--paginate`. Besides, no other option handled by that `handle_options()` function is relevant to Scalar, therefore the cost of refactoring vastly would outweigh the benefit.

2022-01-28diff-filter: be more careful when looking for negative bitsJohannes Schindelin3-17/+21
The `--diff-filter=<bits>` option allows to filter the diff by certain criteria, for example `R` to only show renamed files. It also supports negating a filter via a down-cased letter, i.e. `r` to show _everything but_ renamed files. However, the code is a bit overzealous when trying to figure out whether `git diff` should start with all diff-filters turned on because the user provided a lower-case letter: if the `--diff-filter` argument starts with an upper-case letter, we must not start with all bits turned on. Even worse, it is possible to specify the diff filters in multiple, separate options, e.g. `--diff-filter=AM [...] --diff-filter=m`. Let's accumulate the include/exclude filters independently, and only special-case the "only exclude filters were specified" case after parsing the options altogether. Note: The code replaced by this commit took pains to avoid setting any unused bits of `options->filter`. That was unnecessary, though, as all accesses happen via the `filter_bit_tst()` function using specific bits, and setting the unused bits has no effect. Therefore, we can simplify the code by using `~0` (or in this instance, `~<unwanted-bit>`).
