2022-01-05Merge branch 'en/keep-cwd'Junio C Hamano13-22/+442
Many git commands that deal with working tree files try to remove a directory that becomes empty (i.e. "git switch" from a branch that has the directory to another branch that does not would attempt remove all files in the directory and the directory itself). This drops users into an unfamiliar situation if the command was run in a subdirectory that becomes subject to removal due to the command. The commands have been taught to keep an empty directory if it is the directory they were started in to avoid surprising users. * en/keep-cwd: t2501: simplify the tests since we can now assume desired behavior dir: new flag to remove_dir_recurse() to spare the original_cwd dir: avoid incidentally removing the original_cwd in remove_path() stash: do not attempt to remove startup_info->original_cwd rebase: do not attempt to remove startup_info->original_cwd clean: do not attempt to remove startup_info->original_cwd symlinks: do not include startup_info->original_cwd in dir removal unpack-trees: add special cwd handling unpack-trees: refuse to remove startup_info->original_cwd setup: introduce startup_info->original_cwd t2501: add various tests for removing the current working directory

2022-01-05grep: align default colors with GNU grep onesLénaïc Huard1-3/+3
git-grep shares a lot of options with the standard grep tool. Like GNU grep, it has coloring options to highlight the matching text. And like it, it has options to customize the various colored parts. This patch updates the default git-grep colors to make them match the GNU grep default ones [1]. It was possible to get the same result by setting the various `color.grep.<slot>` options, but this patch makes `git grep --color` share the same color scheme as `grep --color` by default without any user configuration.

2022-01-04stash: do not return before restoring untracked filesElijah Newren2-4/+29
In commit bee8691f19 ("stash: restore untracked files AFTER restoring tracked files", 2021-09-10), we correctly identified that we should restore changes to tracked files before attempting to restore untracked files, and accordingly moved the code for restoring untracked files a few lines down in do_apply_stash(). Unfortunately, the intervening lines had some early return statements meaning that we suddenly stopped restoring untracked files in some cases. Even before the previous commit, there was another possible issue with the current code -- a post-stash-apply 'git status' that was intended to be run after restoring the stash was skipped when we hit a conflict (or other error condition), which seems slightly inconsistent. Fix both issues by saving the return status, and letting other functionality run before returning. Reported-by: AJ Henderson Test-case-by: Randall S.

2022-01-04subtree: fix argument handling in check_parentsJames Limbouris1-4/+3
315a84f9aa0 (subtree: use commits before rejoins for splits, 2018-09-28) changed the signature of check_parents from 'check_parents [REV...]' to 'check_parents PARENTS_EXPR INDENT'. In other words the variable list of parent revisions became a list embedded in a string. However it neglected to unpack the list again before sending it to cache_miss, leading to incorrect calls whenever more than one parent was present. This is the case whenever a merge commit is processed, with the end result being a loss of performance from unecessary rechecks. The indent parameter was subsequently removed in e9525a8a029 (subtree: have $indent actually affect indentation, 2021-04-27), but the argument handling bug remained. For consistency, take multiple arguments in check_parents, and pass all of them to cache_miss separately.

2021-12-30sparse-checkout: refuse to add to bad patternsDerrick Stolee3-3/+9
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.

2021-12-30sparse-checkout: fix segfault on malformed patternsDerrick Stolee2-3/+22
Then core.sparseCheckoutCone is enabled, the sparse-checkout patterns are used to populate two hashsets that accelerate pattern matching. If the user modifies the sparse-checkout file outside of the 'sparse-checkout' builtin, then strange patterns can happen, triggering some error checks. One of these error checks is possible to hit when some special characters exist in a line. A warning message is correctly written to stderr, but then there is additional logic that attempts to remove the line from the hashset and free the data. This leads to a segfault in the 'git sparse-checkout list' command because it iterates over the contents of the hashset, which is now invalid. The fix here is to stop trying to remove from the hashset. In addition, we disable cone mode sparse-checkout because of the malformed data. This results in the pattern-matching working with a possibly-slower algorithm, but using the patterns as they are in the sparse-checkout file. This also changes the behavior of commands such as 'git sparse-checkout list' because the output patterns will be the contents of the sparse-checkout file instead of the list of directories. This is an existing behavior for other types of bad patterns. Add a test that triggers the segfault without the code change.

We encourage identifying what, among many topics on `next`, exact topics a new work depends on, instead of building directly on `next`. Let's clarify this in the documentation. Developers should know what they are building on top of, and be aware of which part of the system is currently being worked on. Encouraging them to make trial merges to `next` and `seen` themselves will incentivize them to read others' changes and understand them, eventually helping the developers to coordinate among themselves and reviewing each others' changes.

2021-12-30cat-file: use GET_OID_ONLY_TO_DIE in --(textconv|filters)Ævar Arnfjörð Bjarmason4-14/+14
Change the cat_one_file() logic that calls get_oid_with_context() under --textconv and --filters to use the GET_OID_ONLY_TO_DIE flag, thus improving the error messaging emitted when e.g. <path> is missing but <rev> is not. To service the "cat-file" use-case we need to introduce a new "GET_OID_REQUIRE_PATH" flag, otherwise it would exit early as soon as a valid "HEAD" was resolved, but in the "cat-file" case being changed we always need a valid revision and path. This arguably makes the "<bad rev>:<bad path>" and "<bad rev>:<good (in HEAD) path>" use cases worse, as we won't quote the <path> component at the user anymore, but let's just use the existing logic "git log" et al use for now.

Stop having GET_OID_ONLY_TO_DIE imply GET_OID_QUIETLY in get_oid_with_context_1(). The *_DIE flag was added in 33bd598c390 (sha1_name.c: teach lookup context to get_sha1_with_context(), 2012-07-02), and then later tweaked in 7243ffdd78d (get_sha1: avoid repeating ourselves via ONLY_TO_DIE, 2016-09-26). Everything in that commit makes sense, but only for callers that expect to fail in an initial call to get_oid_with_context_1(), e.g. as "git show 0017" does via handle_revision_arg(), and then would like to call get_oid_with_context_1() again via this maybe_die_on_misspelt_object_name() function. In the subsequent commit we'll add a new caller that expects to call this only once, but who would still like to have all the error messaging that GET_OID_ONLY_TO_DIE gives it, in addition to any regular errors.

With the migration of --batch-all-objects to OPT_CMDMODE() in the preceding commit one bug with combining it and other OPT_CMDMODE() options was solved, but we were still left with e.g. --buffer silently being discarded when not in batch mode. Fix all those bugs, and in addition emit errors telling the user specifically what options can't be combined with what other options, before this we'd usually just emit the cryptic usage text and leave the users to work it out by themselves. This change is rather large, because to do so we need to untangle the options processing so that we can not only error out, but emit sensible errors, and e.g. emit errors about options before errors about stray argc elements (as they might become valid if the option were removed). Some of the output changes ("error:" to "fatal:" with usage_msg_opt[f]()), but none of the exit codes change, except in those cases where we silently accepted bad option combinations before, now we'll error out.

It doesn't combine with --filters, --textconv etc. By giving parse_options() information about what options are mutually exclusive with one another we can get the die() message being removed here for free, we didn't even use that removed message in some cases, e.g. for both of: --batch-all-objects --textconv --batch-all-objects --filters We'd take the "goto usage" in the "if (opt)" branch, and never reach the previous message.

The opening line of the DESCRIPTION section is also "In its first form[...]", which refers to "git cat-file <type> <object>", but the SYNOPSIS section wasn't showing that as the first form! That part of the documentation made sense in d83a42f34a6 (Documentation: minor grammatical fixes in git-cat-file.txt, 2009-03-22) when it was introduced, but since then various options that were added have made that intro make no sense in the context it was in.

The disconnect between the "..." and "fmt" is a bit unusual, but it works just fine and this keeps it consistent with usage_msg_opt(), i.e. a caller of it can be moved to usage_msg_optf() and not have to have its arguments re-arranged.

2021-12-30cat-file tests: test messaging on bad objects/pathsÆvar Arnfjörð Bjarmason1-0/+42
Add tests for the output that's emitted when we disambiguate <obj>:<path> in cat-file. This gives us a baseline for improving these messages. For e.g. "git blame" we'll emit: $ git blame HEAD:foo fatal: no such path 'HEAD:foo' in HEAD But cat-file doesn't disambiguate these two cases, and just gives the rather unhelpful: $ git cat-file --textconv HEAD:foo fatal: Not a valid object name HEAD:foo Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2021-12-30cat-file tests: test bad usageÆvar Arnfjörð Bjarmason1-0/+94
Stress test the usage emitted when options are combined in ways that isn't supported. Let's test various option combinations, some of these we buggily allow right now. E.g. this reveals a bug in 321459439e1 (cat-file: support --textconv/--filters in batch mode, 2016-09-09) that we'll fix in a subsequent commit. We're supposed to be emitting a relevant message when --batch-all-objects is combined with --textconv or --filters, but we don't. The cases of needing to assign to opt=2 in the "opt" loop are because on those we do the right thing already, in subsequent commits the "test_expect_failure" cases will be fixed, and the for-loops unified.

2021-12-30merge-ort: fix bug with renormalization and rename/delete conflictsElijah Newren2-3/+42
Ever since commit a492d5331c ("merge-ort: ensure we consult df_conflict and path_conflicts", 2021-06-30), when renormalization is active AND a file is involved in a rename/delete conflict BUT the file is unmodified (either before or after renormalization), merge-ort was running into an assertion failure. Prior to that commit (or if assertions were compiled out), merge-ort would mis-merge instead, ignoring the rename/delete conflict and just deleting the file. Remove the assertions, fix the code appropriately, leave some good comments in the code, and add a testcase for this situation.

2021-12-25Makefile: don't invoke msgfmt with --statisticsÆvar Arnfjörð Bjarmason1-1/+1
Remove the --statistics flag that I added in 5e9637c6297 (i18n: add infrastructure for translating Git with gettext, 2011-11-18). Our Makefile output is good about reducing verbosity by default, except in this case: $ rm -rf po/build/locale/e*; time make -j $(nproc) all SUBDIR templates MKDIR -p po/build/locale/el/LC_MESSAGES MSGFMT po/build/locale/el/LC_MESSAGES/git.mo MKDIR -p po/build/locale/es/LC_MESSAGES MSGFMT po/build/locale/es/LC_MESSAGES/git.mo 1038 translated messages, 3325 untranslated messages. 5230 translated messages. I didn't have any good reason for using --statistics at the time other than ad-hoc eyeballing of the output. We don't need to spew out exactly how many messages we've got translated every time. Now we'll instead emit: $ rm -rf po/build/locale/e*; time make -j $(nproc) all SUBDIR templates MKDIR -p po/build/locale/el/LC_MESSAGES MSGFMT po/build/locale/el/LC_MESSAGES/git.mo MKDIR -p po/build/locale/es/LC_MESSAGES MSGFMT po/build/locale/es/LC_MESSAGES/git.mo Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2021-12-25Makefile: move -DPAGER_ENV from BASIC_CFLAGS to EXTRA_CPPFLAGSÆvar Arnfjörð Bjarmason1-5/+6
Remove -DPAGER_ENV from the BASIC_CFLAGS and instead have it passed via the EXTRA_CPPFLAGS passed when compiling pager.c. This doesn't change anything except to make it clear that only pager.c needs this, as it's the only user of this define. See 995bc22d7f8 (pager: move pager-specific setup into the build, 2016-08-04) for the commit that originally added this.

2021-12-25Makefile: correct the dependency graph of hook-list.hÆvar Arnfjörð Bjarmason1-2/+2
Fix an issue in my cfe853e66be (hook-list.h: add a generated list of hooks, like config-list.h, 2021-09-26), the builtin/help.c was inadvertently made to depend on hook-list.h, but it's used by builtin/bugreport.c. The hook.c also does not depend on hook-list.h. It did in an earlier version of the greater series cfe853e66be was extracted from, but not anymore. We might end up needing that line again, but let's remove it for now.

2021-12-25t/perf: do not run tests in user's $SHELLJohannes Altmanninger1-1/+1
The environment variable $SHELL is usually set to the user's interactive shell. Our build and test scripts never use $SHELL because there are no guarantees about its input language. Instead, we use /bin/sh which should be a POSIX shell. For systems with a broken /bin/sh, we allow to override that path via SHELL_PATH. To run tests in yet another shell we allow to override SHELL_PATH with TEST_SHELL_PATH. Perf tests run in $SHELL via a wrapper defined in t/perf/perf-lib.sh, so they break with e.g. SHELL=python. Use TEST_SHELL_PATH like in other tests. TEST_SHELL_PATH is always defined because t/perf/perf-lib.sh includes t/test-lib.sh, which includes GIT-BUILD-OPTIONS.
