2021-12-15am: support --allow-empty to record specific empty patchesLibravatar 徐沛文 (Aleen)1-0/+57
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".

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>
2021-12-13tests: fix broken &&-chains in `{...}` groupsLibravatar Eric Sunshine1-1/+1
The top-level &&-chain checker built into t/test-lib.sh causes tests to magically exit with code 117 if the &&-chain is broken. However, it has the shortcoming that the magic does not work within `{...}` groups, `(...)` subshells, `$(...)` substitutions, or within bodies of compound statements, such as `if`, `for`, `while`, `case`, etc. `chainlint.sed` partly fills in the gap by catching broken &&-chains in `(...)` subshells, but bugs can still lurk behind broken &&-chains in the other cases. Fix broken &&-chains in `{...}` groups in order to reduce the number of possible lurking bugs.

2020-11-19t4*: adjust the references to the default branch name "main"Libravatar Johannes Schindelin1-14/+14
Carefully excluding t4013 and t4015, which see independent development elsewhere at the time of writing, we use `main` as the default branch name in t4*. This trick was performed via $ (cd t && sed -i -e 's/master/main/g' -e 's/MASTER/MAIN/g' \ -e 's/Master/Main/g' -- t4*.sh t4211/*.export && git checkout HEAD -- t4013\*) This allows us to define `GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=main` for those tests.

2020-11-19tests: mark tests relying on the current default for `init.defaultBranch`Libravatar Johannes Schindelin1-0/+3
In addition to the manual adjustment to let the `linux-gcc` CI job run the test suite with `master` and then with `main`, this patch makes sure that GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME is set in all test scripts that currently rely on the initial branch name being `master by default. To determine which test scripts to mark up, the first step was to force-set the default branch name to `master` in - all test scripts that contain the keyword `master`, - t4211, which expects `t/t4211/history.export` with a hard-coded ref to initialize the default branch, - t5560 because it sources `t/t556x_common` which uses `master`, - t8002 and t8012 because both source `t/annotate-tests.sh` which also uses `master`) This trick was performed by this command: $ sed -i '/^ *\. \.\/\(test-lib\|lib-\(bash\|cvs\|git-svn\)\|gitweb-lib\)\.sh$/i\ GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=master\ export GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME\ ' $(git grep -l master t/t[0-9]*.sh) \ t/t4211*.sh t/t5560*.sh t/t8002*.sh t/t8012*.sh After that, careful, manual inspection revealed that some of the test scripts containing the needle `master` do not actually rely on a specific default branch name: either they mention `master` only in a comment, or they initialize that branch specificially, or they do not actually refer to the current default branch. Therefore, the aforementioned modification was undone in those test scripts thusly: $ git checkout HEAD -- \ t/t0027-auto-crlf.sh t/t0060-path-utils.sh \ t/t1011-read-tree-sparse-checkout.sh \ t/t1305-config-include.sh t/t1309-early-config.sh \ t/t1402-check-ref-format.sh t/t1450-fsck.sh \ t/t2024-checkout-dwim.sh \ t/t2106-update-index-assume-unchanged.sh \ t/t3040-subprojects-basic.sh t/t3301-notes.sh \ t/t3308-notes-merge.sh t/t3423-rebase-reword.sh \ t/t3436-rebase-more-options.sh \ t/t4015-diff-whitespace.sh t/t4257-am-interactive.sh \ t/t5323-pack-redundant.sh t/t5401-update-hooks.sh \ t/t5511-refspec.sh t/t5526-fetch-submodules.sh \ t/t5529-push-errors.sh t/t5530-upload-pack-error.sh \ t/t5548-push-porcelain.sh \ t/t5552-skipping-fetch-negotiator.sh \ t/t5572-pull-submodule.sh t/t5608-clone-2gb.sh \ t/t5614-clone-submodules-shallow.sh \ t/t7508-status.sh t/t7606-merge-custom.sh \ t/t9302-fast-import-unpack-limit.sh We excluded one set of test scripts in these commands, though: the range of `git p4` tests. The reason? `git p4` stores the (foreign) remote branch in the branch called `p4/master`, which is obviously not the default branch. Manual analysis revealed that only five of these tests actually require a specific default branch name to pass; They were modified thusly: $ sed -i '/^ *\. \.\/lib-git-p4\.sh$/i\ GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=master\ export GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME\ ' t/t980[0167]*.sh t/t9811*.sh Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2020-09-26tests: avoid variations of the `master` branch nameLibravatar Johannes Schindelin1-4/+4
The term `master` has a loaded history that serves as a constant reminder of racial injustice. The Git project has no desire to perpetuate this and already started avoiding it. The test suite uses variations of this name for branches other than the default one. Apart from t3200, where we just addressed this in the previous commit, those instances can be renamed in an automated manner because they do not require any changes outside of the test script, so let's do that. Seeing as the touched branches have very little (if anything) to do with the default branch, we choose to use a completely separate naming scheme: `topic_<number>` (it cannot be `topic-<number>` because t5515 uses the `test_oid` machinery with the term, and that machinery uses shell variables internally, whose names cannot contain dashes).

2020-08-06t: don't spuriously close and reopen quotesLibravatar Martin Ågren1-4/+4
In the test scripts, the recommended style is, e.g.: test_expect_success 'name' ' do-something somehow && do-some-more testing ' When using this style, any single quote in the multi-line test section is actually closing the lone single quotes that surround it. It can be a non-issue in practice: test_expect_success 'sed a little' ' sed -e 's/hi/lo/' in >out # "ok": no whitespace in s/hi/lo/ ' Or it can be a bug in the test, e.g., because variable interpolation happens before the test even begins executing: v=abc test_expect_success 'variable interpolation' ' v=def && echo '"$v"' # abc ' Change several such in-test single quotes to use double quotes instead or, in a few cases, drop them altogether. These were identified using some crude grepping. We're not fixing any test bugs here, but we're hopefully making these tests slightly easier to grok and to maintain. There are legitimate use cases for closing a quote and opening a new one, e.g., both '\'' and '"'"' can be used to produce a literal single quote. I'm not touching any of those here.

2020-02-20am: support --show-current-patch=raw as a synonym for--show-current-patchLibravatar Paolo Bonzini1-0/+10
When "git am --show-current-patch" was added in commit 984913a210 ("am: add --show-current-patch", 2018-02-12), "git am" started recommending it as a replacement for .git/rebase-merge/patch. Unfortunately the suggestion is somewhat misguided; for example, the output "git am --show-current-patch" cannot be passed to "git apply" if it is encoded as quoted-printable or base64. To simplify worktree operations and to avoid that users poke into .git, it would be better if "git am" also provided a mode that copies .git/rebase-merge/patch to stdout. One possibility could be to have completely separate options, introducing for example --show-current-message (for .git/rebase-apply/NNNN) and --show-current-diff (for .git/rebase-apply/patch), while possibly deprecating --show-current-patch. That would even remove the need for the first two patches in the series. However, the long common prefix would have prevented using an abbreviated option such as "--show". Therefore, I chose instead to add a string argument to --show-current-patch. The new argument is optional, so that "git am --show-current-patch"'s behavior remains backwards-compatible. The next choice to make is how to handle multiple --show-current-patch options. Right now, something like "git am --abort --show-current-patch" is rejected, and the previous suggestion would likewise have naturally rejected a command line like git am --show-current-message --show-current-diff Therefore, I decided to also reject for example git am --show-current-patch=diff --show-current-patch=raw In other words the whole of --show-current-patch=xxx (including the optional argument) is treated as the command mode. I found this to be more consistent and intuitive, even though it differs from the usual "last one wins" semantics of the git command line. Add the code to parse submodes based on the above design, where for now "raw" is the only valid submode. "raw" prints the full e-mail message just like "git am --show-current-patch".

2019-09-03am: reload .gitattributes after patching itLibravatar brian m. carlson1-0/+52
When applying multiple patches with git am, or when rebasing using the am backend, it's possible that one of our patches has updated a gitattributes file. Currently, we cache this information, so if a file in a subsequent patch has attributes applied, the file will be written out with the attributes in place as of the time we started the rebase or am operation, not with the attributes applied by the previous patch. This problem does not occur when using the -m or -i flags to rebase. To ensure we write the correct data into the working tree, expire the cache after each patch that touches a path ending in ".gitattributes". Since we load these attributes in multiple separate files, we must expire them accordingly. Verify that both the am and rebase code paths work correctly, including the conflict marker size with am -3.

Using 'test_must_be_empty' is preferable to '! test -s', because it gives a helpful error message if the given file is unexpectedly not empty, while the latter remains completely silent. Furthermore, it also catches cases when the given file unexpectedly does not exist at all. This patch was basically created by: sed -i -e 's/! test -s/test_must_be_empty/' t[0-9]*.sh with the following notable exceptions: - The '! test -s' check in '.gitmodules ignore=dirty suppresses submodules with untracked content' in 't7508-status.sh' is left as-is, because it's bogus and, therefore, it's subject of a dedicated patch. - The '! test -s' checks in 't9131-git-svn-empty-symlink.sh' and 't9135-git-svn-moved-branch-empty-file.sh' are immediately preceeded by a 'test -f' to ensure that the files exist in the first place. 'test_must_be_empty' ensures that as well, so those 'test -f' commands are removed as well. Signed-off-by: SZEDER Gábor <szeder.dev@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2018-08-06t4150: fix broken test for am --scissorsLibravatar Andrei Rybak1-19/+20
Tests for "git am --[no-]scissors" [1] work in the following way: 1. Create files with commit messages 2. Use these files to create expected commits 3. Generate eml file with patch from expected commits 4. Create commits using git am with these eml files 5. Compare these commits with expected The test for "git am --scissors" is supposed to take an e-mail with a scissors line and in-body "Subject:" header and demonstrate that the subject line from the e-mail itself is overridden by the in-body header and that only text below the scissors line is included in the commit message of the commit created by the invocation of "git am --scissors". However, the setup of the test incorrectly uses a commit without the scissors line and without the in-body header in the commit message, producing eml file not suitable for testing of "git am --scissors". This can be checked by intentionally breaking is_scissors_line function in mailinfo.c, for example, by changing string ">8", which is used by the test. With such change the test should fail, but does not. Fix broken test by generating eml file with scissors line and in-body header "Subject:". Since the two tests for --scissors and --no-scissors options are there to test cutting or keeping the commit message, update both tests to change the test file in the same way, which allows us to generate only one eml file to be passed to git am. To clarify the intention of the test, give files and tags more explicit names.

Linus noticed that the recently reimplemented "git am -s" defines the trailer block too rigidly, resulting in an unnecessary blank line between the existing sign-offs and his new sign-off. An e-mail submission sent to Linus in real life ends with mixture of sign-offs and commentaries, e.g. title here message here Signed-off-by: Original Author <original@auth.or> [rv: tweaked frotz and nitfol] Signed-off-by: Re Viewer <rv@ew.er> Signed-off-by: Other Reviewer <other@rev.ewer> --- patch here Because the reimplementation reused append_signoff() helper that is used by other codepaths, which is unaware that people intermix such comments with their sign-offs in the trailer block, such a message was judged to end with a non-trailer, resulting in an extra blank line before adding a new sign-off. The original scripted version of "git am" used a lot looser definition, i.e. "if and only if there is no line that begins with Signed-off-by:, add a blank line before adding a new sign-off". For the upcoming release, stop using the append_signoff() in "git am" and reimplement the looser definition used by the scripted version to use only in "git am" to fix this regression in "am" while avoiding new regressions to other users of append_signoff(). In the longer term, we should look into loosening append_signoff() so that other codepaths that add a new sign-off behave the same way as "git am -s", but that is a task for post-release.

2015-09-01rerere: release lockfile in non-writing functionsLibravatar Jeff King1-0/+36
There's a bug in builtin/am.c in which we take a lock on MERGE_RR recursively. But rather than fix am.c, this patch fixes the confusing interface from rerere.c that caused the bug. Read on for the gory details. The setup_rerere() function both reads the existing MERGE_RR file, and takes MERGE_RR.lock. In the rerere() and rerere_forget() functions, we end up in write_rr(), which will then commit the lock file. But for functions like rerere_clear() that do not write to MERGE_RR, we expect the caller to have handled setup_rerere(). That caller would then need to release the lockfile, but it can't; the lock struct is local to rerere.c. For builtin/rerere.c, this is OK. We run a single rerere operation and then exit immediately, which has the side effect of rolling back the lockfile. But in builtin/am.c, this is actively wrong. If we run "git am -3 --skip", we call setup-rerere twice without releasing the lock: 1. The "--skip" causes us to call am_rerere_clear(), which calls setup_rerere(), but never drops the lock. 2. We then proceed to the next patch. 3. The "--3way" may cause us to call rerere() to handle conflicts in that patch, but we are already holding the lock. The lockfile code dies with: BUG: prepare_tempfile_object called for active object We could fix this by having rerere_clear() call rollback_lock_file(). But it feels a bit odd for it to roll back a lockfile that it did not itself take. So let's simplify the interface further, and handle setup_rerere in the function itself, taking away the question from the caller over whether they need to do so. We can give rerere_gc() the same treatment, as well (even though it doesn't have any callers besides builtin/rerere.c at this point). Note that these functions don't take flags from their callers to pass along to setup_rerere; that's OK, because the flags would not be meaningful for what they are doing. Both of those functions need to hold the lock because even though they do not write to MERGE_RR, they are still writing and should be protected from a simultaneous "rerere" run. But rerere_remaining(), "rerere diff", and "rerere status" are all read-only operations. They want to setup_rerere(), but do not care about taking the lock in the first place. Since our update of MERGE_RR is the usual atomic rename done by commit_lock_file, they can just do a lockless read. For that, we teach setup_rerere a READONLY flag to avoid the lock. As a bonus, this pushes builtin/rerere.c's setup_rerere call closer to the functions that use it.

2015-07-24Revert "git-am: add am.threeWay config variable"Libravatar Junio C Hamano1-19/+0
This reverts commit d96a275b91bae1800cd43be0651e886e7e042a17. It used to be possible to apply a patch series with "git am mbox" and then only after seeing a failure, switch to three-way mode via "git am -3" (no other options or arguments). The commit being reverted broke this workflow. Signed-off-by: Junio C Hamano <gitster@pobox.com>

2015-06-15am: use gmtime() to parse mercurial patch dateLibravatar Paul Tan1-0/+23
An example of the line in a mercurial patch that specifies the date of the commit would be: # Date 1433753301 25200 where the first number is the number of seconds since the unix epoch (in UTC), and the second number is the offset of the timezone, in second s west of UTC (negative if the timezone is east of UTC). git-am uses localtime() to break down the first number into its components (year, month, day, hours, minutes, seconds etc.). However, the returned components are relative to the user's time zone. As a result, if the user's time zone does not match the time zone specified in the patch, the resulting commit will have the wrong author date. Fix this by using gmtime() instead, which uses UTC instead of the user's time zone. Signed-off-by: Paul Tan <pyokagan@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
