2021-06-06parallel-checkout: avoid dash local bug in testsLibravatar René Scharfe1-1/+1
Dash bug https://bugs.launchpad.net/ubuntu/+source/dash/+bug/139097 lets the shell erroneously perform field splitting on the expansion of a command substitution during declaration of a local variable. It causes the parallel-checkout tests to fail e.g. when running them with /bin/dash on MacOS 11.4, where they error out like this: ./t2080-parallel-checkout-basics.sh: 33: local: 0: bad variable name That's because the output of wc -l contains leading spaces and the returned number of lines is treated as another variable to declare, i.e. as in "local workers= 0". Work around it by enclosing the command substitution in quotes.

2021-05-27t2080: fix cp invocation to copy symlinks instead of following themLibravatar Matheus Tavares1-1/+1
t2080 makes a few copies of a test repository and later performs a branch switch on each one of the copies to verify that parallel checkout and sequential checkout produce the same results. However, the repository is copied with `cp -R` which, on some systems, defaults to following symlinks on the directory hierarchy and copying their target files instead of copying the symlinks themselves. AIX is one example of system where this happens. Because the symlinks are not preserved, the copied repositories have paths that do not match what is in the index, causing git to abort the checkout operation that we want to test. This makes the test fail on these systems. Fix this by copying the repository with the POSIX flag '-P', which forces cp to copy the symlinks instead of following them. Note that we already use this flag for other cp invocations in our test suite (see t7001). With this change, t2080 now passes on AIX.

2021-05-27send-email: don't needlessly abs_path() the core.hooksPathLibravatar Ævar Arnfjörð Bjarmason1-3/+4
In c8243933c74 (git-send-email: Respect core.hooksPath setting, 2021-03-23) we started supporting core.hooksPath in "send-email". It's been reported that on Windows[1] doing this by calling abs_path() results in different canonicalizations of the absolute path. This wasn't an issue in c8243933c74 itself, but was revealed by my ea7811b37e0 (git-send-email: improve --validate error output, 2021-04-06) when we started emitting the path to the hook, which was previously only internal to git-send-email.perl. The just-landed 53753a37d09 (t9001-send-email.sh: fix expected absolute paths on Windows, 2021-05-24) narrowly fixed this issue, but I believe we can do better here. We should not be relying on whatever changes Perl's abs_path() makes to the path "rev-parse --git-path hooks" hands to us. Let's instead trust it, and hand it to Perl's system() in git-send-email.perl. It will handle either a relative or absolute path. So let's revert most of 53753a37d09 and just have "hooks_path" return what we get from "rev-parse" directly without modification. This has the added benefit of making the error message friendlier in the common case, we'll no longer print an absolute path for repository-local hook errors. 1. http://lore.kernel.org/git/bb30fe2b-cd75-4782-24a6-08bb002a0367@kdbg.org Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2021-05-25t1092: use GIT_PROGRESS_DELAY for consistent resultsLibravatar Derrick Stolee1-3/+3
The t1092-sparse-checkout-compatibility.sh tests compare the stdout and stderr for several Git commands across both full checkouts, sparse checkouts with a full index, and sparse checkouts with a sparse index. Since these are direct comparisons, sometimes a progress indicator can flush at unpredictable points, especially on slower machines. This causes the tests to be flaky. One standard way to avoid this is to add GIT_PROGRESS_DELAY=0 to the Git commands that are run, as this will force every progress indicator created with start_progress_delay() to be created immediately. However, there are some progress indicators that are created in the case of a full index that are not created with a sparse index. Moreover, their values may be different as those indexes have a different number of entries. Instead, use GIT_PROGRESS_DELAY=-1 (which will turn into UINT_MAX) to ensure that any reasonable machine running these tests would never display delayed progress indicators.

2021-05-25init: fix bug regarding ~/ expansion in init.templateDirLibravatar Matheus Tavares1-8/+20
We used to read the init.templateDir setting at builtin/init-db.c using a git_config() callback that, in turn, called git_config_pathname(). To simplify the config reading logic at this file and plug a memory leak, this was replaced by a direct call to git_config_get_value() at e4de4502e6 ("init: remove git_init_db_config() while fixing leaks", 2021-03-14). However, this function doesn't provide path expanding semantics, like git_config_pathname() does, so paths with '~/' and '~user/' are treated literally. This makes 'git init' fail to handle init.templateDir paths using these constructs: $ git config init.templateDir '~/templates_dir' $ git init 'warning: templates not found in ~/templates_dir' Replace the git_config_get_value() call by git_config_get_pathname(), which does the '~/' and '~user/' expansions. Also add a regression test. Note that unlike git_config_get_value(), the config cache does not own the memory for the path returned by git_config_get_pathname(), so we must free() it.

2021-05-25t9001-send-email.sh: fix expected absolute paths on WindowsLibravatar Johannes Sixt1-4/+3
Git for Windows is a native Windows program that works with native absolute paths in the drive letter style C:\dir. The auxiliary infrastructure is based on MSYS2, which uses POSIX style /C/dir. When we test for output of absolute paths produced by git.exe, we usally have to expect C:\dir style paths. To produce such expected paths, we have to use $(pwd) in the test scripts; the alternative, $PWD, produces a POSIX style path. ($PWD is a shell variable, and the shell is bash, an MSYS2 program, and operates in the POSIX realm.) There are two recently added tests that were written to expect C:\dir paths. The output that is tested is produced by `git send-email`, but behind the scenes, this is a Perl script, which also works in the POSIX realm and produces /C/dir style output. In the first test case that is changed here, replace $(pwd) by $PWD so that the expected path is constructed using /C/dir style. The second test case sets core.hooksPath to an absolute path. Since the test script talks to native git.exe, it is supposed to place a C:/dir style path into the configuration; therefore, keep $(pwd). When this configuration value is consumed by the Perl script, it is transformed to /C/dir style by the MSYS2 layer and echoed back in this form in the error message. Hence, do use $PWD for the expected value. Signed-off-by: Johannes Sixt <j6t@kdbg.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>

If options pertaining to how the diff is displayed is provided to `git stash show`, the command will ignore the stash.showIncludeUntracked configuration variable, defaulting to not showing any untracked files. This is unintuitive behaviour since the format of the diff output and whether or not to display untracked files are orthogonal. Use stash.showIncludeUntracked even when diff options are given. Of course, this is still overridable via the command-line options. Update the documentation to explicitly say which configuration variables will be overridden when a diff options are given.

2021-05-21diff-merges: let "-m" imply "-p"Libravatar Sergey Organov1-2/+2
Fix long standing inconsistency between -c/--cc that do imply -p on one side, and -m that did not imply -p on the other side. Change corresponding test accordingly, as "log -m" output should now match one from "log -m -p", rather than from just "log". Change documentation accordingly. NOTES: After this patch git log -m produces diffs without need to provide -p as well, that improves both consistency and usability. It gets even more useful if one sets "log.diffMerges" configuration variable to "first-parent" to force -m produce usual diff with respect to first parent only. This patch, however, does not change behavior when specific diff format is explicitly provided on the command-line, so that commands like git log -m --raw git log -m --stat are not affected, nor does it change commands where specific diff format is active by default, such as: git diff-tree -m It's also worth to be noticed that exact historical semantics of -m is still provided by --diff-merges=separate.

2021-05-20merge-ort, diffcore-rename: employ cached renames when possibleLibravatar Elijah Newren1-20/+28
When there are many renames between the old base of a series of commits and the new base, the way sequencer.c, merge-recursive.c, and diffcore-rename.c have traditionally split the work resulted in redetecting the same renames with each and every commit being transplanted. To address this, the last several commits have been creating a cache of rename detection results, determining when it was safe to use such a cache in subsequent merge operations, adding helper functions, and so on. See the previous half dozen commit messages for additional discussion of this optimization, particularly the message a few commits ago entitled "add code to check for whether cached renames can be reused". This commit finally ties all of that work together, modifying the merge algorithm to make use of these cached renames. For the testcases mentioned in commit 557ac0350d ("merge-ort: begin performance work; instrument with trace2_region_* calls", 2020-10-28), this change improves the performance as follows: Before After no-renames: 5.665 s ± 0.129 s 5.622 s ± 0.059 s mega-renames: 11.435 s ± 0.158 s 10.127 s ± 0.073 s just-one-mega: 494.2 ms ± 6.1 ms 500.3 ms ± 3.8 ms That's a fairly small improvement, but mostly because the previous optimizations were so effective for these particular testcases; this optimization only kicks in when the others don't. If we undid the basename-guided rename detection and skip-irrelevant-renames optimizations, then we'd see that this series by itself improved performance as follows: Before Basename Series After Just This Series no-renames: 13.815 s ± 0.062 s 5.697 s ± 0.080 s mega-renames: 1799.937 s ± 0.493 s 205.709 s ± 0.457 s Since this optimization kicks in to help accelerate cases where the previous optimizations do not apply, this last comparison shows that this cached-renames optimization has the potential to help signficantly in cases that don't meet the requirements for the other optimizations to be effective. The changes made in this optimization also lay some important groundwork for a future optimization around having collect_merge_info() avoid recursing into subtrees in more cases. However, for this optimization to be effective, merge_switch_to_result() should only be called when the rebase or cherry-pick operation has either completed or hit a case where the user needs to resolve a conflict or edit the result. If it is called after every commit, as sequencer.c does, then the working tree and index are needlessly updated with every commit and the cached metadata is tossed, defeating this optimization. Refactoring sequencer.c to only call merge_switch_to_result() at the end of the operation is a bigger undertaking, and the practical benefits of this optimization will not be realized until that work is performed. Since `test-tool fast-rebase` only updates at the end of the operation, it was used to obtain the timings above.

2021-05-20fast-rebase: write conflict state to working tree, index, and HEADLibravatar Elijah Newren1-19/+32
Previously, when fast-rebase hit a conflict, it simply aborted and left HEAD, the index, and the working tree where they were before the operation started. While fast-rebase does not support restarting from a conflicted state, write the conflicted state out anyway as it gives us a way to see what the conflicts are and write tests that check for them. This will be important in the upcoming commits, because sequencer.c is only superficially integrated with merge-ort.c; in particular, it calls merge_switch_to_result() after EACH merge instead of only calling it at the end of all the sequence of merges (or when a conflict is hit). This not only causes needless updates to the working copy and index, but also causes all intermediate data to be freed and tossed, preventing caching information from one merge to the next. However, integrating sequencer.c more deeply with merge-ort.c is a big task, and making this small extension to fast-rebase.c provides us with a simple way to test the edge and corner cases that we want to make sure continue working.

2021-05-19clone: clean up directory after transport_fetch_refs() failureLibravatar Jeff King1-0/+7
git-clone started respecting errors from the transport subsystem in aab179d937 (builtin/clone.c: don't ignore transport_fetch_refs() errors, 2020-12-03). However, that commit didn't handle the cleanup of the filesystem quite right. The cleanup of the directory that cmd_clone() creates is done by an atexit() handler, which we control with a flag. It starts as JUNK_LEAVE_NONE ("clean up everything"), then progresses to JUNK_LEAVE_REPO when we know we have a valid repo but not working tree, and then finally JUNK_LEAVE_ALL when we have a successful checkout. Most errors cause us to die(), which then triggers the handler to do the right thing based on how far into cmd_clone() we got. But the checks added by aab179d937 instead set the "err" variable and then jump to a new "cleanup" label, which then returns our non-zero status. However, the code after the cleanup label includes setting the flag to JUNK_LEAVE_ALL, and so we accidentally leave the repository and working tree in place. One obvious option to fix this is to reorder the end of the function to set the flag first, before cleanup code, and put the label between them. But we can observe another small bug: the error return from transport_fetch_refs() is generally "-1", and we propagate that to the return value of cmd_clone(), which ultimately becomes the exit code of the process. And we try to avoid transmitting negative values via exit codes (only the low 8 bits are passed along as an unsigned value, though in practice for "-1" this at least retains the property that it's non-zero). Instead, let's just die(). That makes us consistent with rest of the code in the function. It does add a new "fatal:" line to the output, but I'd argue that's a good thing: - in the rare case that the transport code didn't say anything, now the user gets _some_ error message - even if the transport code said something like "error: ssh died of signal 9", it's nice to also say "fatal" to indicate that we considered that to be a show-stopper. Triggering this in the test suite turns out to be surprisingly difficult. Almost every error we'd encounter, including ones deep inside the transport code, cause us to just die() right there! However, one way is to put a fake wrapper around git-upload-pack that sends the complete packfile but exits with a failure code.

2021-05-19Revert "remote-curl: fall back to basic auth if Negotiate fails"Libravatar Jeff King1-1/+1
This reverts commit 1b0d9545bb85912a16b367229d414f55d140d3be. That commit does fix the situation it intended to (avoiding Negotiate even when the credentials were provided in the URL), but it creates a more serious regression: we now never hit the conditional for "we had a username and password, tried them, but the server still gave us a 401". That has two bad effects: 1. we never call credential_reject(), and thus a bogus credential stored by a helper will live on forever 2. we never return HTTP_NOAUTH, so the error message the user gets is "The requested URL returned error: 401", instead of "Authentication failed". Doing this correctly seems non-trivial, as we don't know whether the Negotiate auth was a problem. Since this is a regression in the upcoming v2.23.0 release (for which we're in -rc0), let's revert for now and work on a fix separately. (Note that this isn't a pure revert; the previous commit added a test showing the regression, so we can now flip it to expect_success).

2021-05-19t5551: test http interaction with credential helpersLibravatar Jeff King1-0/+41
We test authentication with http, and we independently test that credential helpers work, but we don't have any tests that cover the two features working together. Let's add two: 1. Make sure that a successful request asks the helper to save the credential. This works as expected. 2. Make sure that a failed request asks the helper to forget the credential. This is marked as expect_failure, as it was recently regressed by 1b0d9545bb (remote-curl: fall back to basic auth if Negotiate fails, 2021-03-22). The symptom here is that the second request should prompt the user, but doesn't. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2021-05-18t7500: remove non-existant C_LOCALE_OUTPUT prereqLibravatar Todd Zullinger1-1/+1
The C_LOCALE_OUTPUT prerequisite was removed in b1e079807b (tests: remove last uses of C_LOCALE_OUTPUT, 2021-02-11), where Ævar noted: I'm not leaving the prerequisite itself in place for in-flight changes as there currently are none that introduce new tests that rely on it, and because C_LOCALE_OUTPUT is currently a noop on the master branch we likely won't have any new submissions that use it. One more use of C_LOCALE_OUTPUT did creep in with 3d1bda6b5b (t7500: add tests for --fixup=[amend|reword] options, 2021-03-15). This causes a number of the tests to be skipped by default: ok 35 # SKIP --fixup=reword: incompatible with --all (missing C_LOCALE_OUTPUT) ok 36 # SKIP --fixup=reword: incompatible with --include (missing C_LOCALE_OUTPUT) ok 37 # SKIP --fixup=reword: incompatible with --only (missing C_LOCALE_OUTPUT) ok 38 # SKIP --fixup=reword: incompatible with --interactive (missing C_LOCALE_OUTPUT) ok 39 # SKIP --fixup=reword: incompatible with --patch (missing C_LOCALE_OUTPUT) Remove the C_LOCALE_OUTPUT prerequisite from these tests so they are not skipped.

2021-05-17rev-parse: fix segfault with missing --path-format argumentLibravatar Wolfgang Müller1-0/+4
Calling "git rev-parse --path-format" without an argument segfaults instead of giving an error message. Commit fac60b8925 (rev-parse: add option for absolute or relative path formatting, 2020-12-13) added the argument parsing code but forgot to handle NULL. Returning an error makes sense here because there is no default value we could use. Add a test case to verify.

2021-05-17git-send-email: add option to specify sendmail commandLibravatar Gregory Anders1-0/+31
The sendemail.smtpServer configuration option and --smtp-server command line option both support using a sendmail-like program to send emails by specifying an absolute file path. However, this is not ideal for the following reasons: 1. It overloads the meaning of smtpServer (now a program is being used for the server?) 2. It doesn't allow for non-absolute paths, arguments, or arbitrary scripting Requiring an absolute path is bad for portability, as the same program may be in different locations on different systems. If a user wishes to pass arguments to their program, they have to use the smtpServerOption option, which is cumbersome (as it must be repeated for each option) and doesn't adhere to normal git conventions. Introduce a new configuration option sendemail.sendmailCmd as well as a command line option --sendmail-cmd that can be used to specify a command (with or without arguments) or shell expression to run to send email. The name of this option is consistent with --to-cmd and --cc-cmd. This invocation honors the user's $PATH so that absolute paths are not necessary. Arbitrary shell expressions are also supported, allowing users to do basic scripting. Give this option a higher precedence over --smtp-server and sendemail.smtpServer, as the new interface is more flexible. For backward compatibility, continue to support absolute paths in --smtp-server and sendemail.smtpServer.
