2020-10-07builtin/checkout: fix `git checkout -p HEAD...` bugLibravatar Denton Liu3-1/+29
Running `git checkout -p` with a merge-base rev results in an error: $ git checkout -p HEAD... usage: git diff-index [-m] [--cached] [<common-diff-options>] <tree-ish> [<path>...] common diff options: -z output diff-raw with lines terminated with NUL. -p output patch format. -u synonym for -p. --patch-with-raw output both a patch and the diff-raw format. --stat show diffstat instead of patch. --numstat show numeric diffstat instead of patch. --patch-with-stat output a patch and prepend its diffstat. --name-only show only names of changed files. --name-status show names and status of changed files. --full-index show full object name on index lines. --abbrev=<n> abbreviate object names in diff-tree header and diff-raw. -R swap input file pairs. -B detect complete rewrites. -M detect renames. -C detect copies. --find-copies-harder try unchanged files as candidate for copy detection. -l<n> limit rename attempts up to <n> paths. -O<file> reorder diffs according to the <file>. -S<string> find filepair whose only one side contains the string. --pickaxe-all show all files diff when -S is used and hit is found. -a --text treat all files as text. Cannot close git diff-index --cached --numstat --summary HEAD... -- () at <redacted>/libexec/git-core/git-add--interactive line 183. This happens because checkout passes the literal argument (in the example, `HEAD...`) to diff-index which does not recognise merge-base revs. Fix this by using the hex of the found commit instead of the given name. Note that "HEAD" is handled specially in run_add_interactive() so it's explicitly not changed. Signed-off-by: Denton Liu <liu.denton@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2020-07-18t3200: don't grep for `strerror()` stringLibravatar Martin Ågren1-2/+2
In 6b7093064a ("t3200: test for specific errors", 2020-06-15), we learned to grep stderr to ensure that the failing `git branch` invocations fail for the right reason. In two of these tests, we grep for "File exists", expecting the string to show up there since config.c calls `error_errno()`, which ends up including `strerror(errno)` in the error message. But as we saw in 4605a73073 ("t1091: don't grep for `strerror()` string", 2020-03-08), there exists at least one implementation where `strerror()` yields a slightly different string than the one we're grepping for. In particular, these tests fail on the NonStop platform. Similar to 4605a73073, grep for the beginning of the string instead to avoid relying on `strerror()` behavior. Reported-by: Randall S.

2020-07-16repository: allow repository format upgrade with extensionsLibravatar Jonathan Nieder3-8/+9
Now that we officially permit repository extensions in repository format v0, permit upgrading a repository with extensions from v0 to v1 as well. For example, this means a repository where the user has set "extensions.preciousObjects" can use "git fetch --filter=blob:none origin" to upgrade the repository to use v1 and the partial clone extension. To avoid mistakes, continue to forbid repository format upgrades in v0 repositories with an unrecognized extension. This way, a v0 user using a misspelled extension field gets a chance to correct the mistake before updating to the less forgiving v1 format. While we're here, make the error message for failure to upgrade the repository format a bit shorter, and present it as an error, not a warning.

2020-07-16Revert "check_repository_format_gently(): refuse extensions for old ↵Libravatar Jonathan Nieder2-11/+16
repositories" This reverts commit 14c7fa269e42df4133edd9ae7763b678ed6594cd. The core.repositoryFormatVersion field was introduced in ab9cb76f661 (Repository format version check., 2005-11-25), providing a welcome bit of forward compatibility, thanks to some welcome analysis by Martin Atukunda. The semantics are simple: a repository with core.repositoryFormatVersion set to 0 should be comprehensible by all Git implementations in active use; and Git implementations should error out early instead of trying to act on Git repositories with higher core.repositoryFormatVersion values representing new formats that they do not understand. A new repository format did not need to be defined until 00a09d57eb8 (introduce "extensions" form of core.repositoryformatversion, 2015-06-23). This provided a finer-grained extension mechanism for Git repositories. In a repository with core.repositoryFormatVersion set to 1, Git implementations can act on "extensions.*" settings that modify how a repository is interpreted. In repository format version 1, unrecognized extensions settings cause Git to error out. What happens if a user sets an extension setting but forgets to increase the repository format version to 1? The extension settings were still recognized in that case; worse, unrecognized extensions settings do *not* cause Git to error out. So combining repository format version 0 with extensions settings produces in some sense the worst of both worlds. To improve that situation, since 14c7fa269e4 (check_repository_format_gently(): refuse extensions for old repositories, 2020-06-05) Git instead ignores extensions in v0 mode. This way, v0 repositories get the historical (pre-2015) behavior and maintain compatibility with Git implementations that do not know about the v1 format. Unfortunately, users had been using this sort of configuration and this behavior change came to many as a surprise: - users of "git config --worktree" that had followed its advice to enable extensions.worktreeConfig (without also increasing the repository format version) would find their worktree configuration no longer taking effect - tools such as copybara[*] that had set extensions.partialClone in existing repositories (without also increasing the repository format version) would find that setting no longer taking effect The behavior introduced in 14c7fa269e4 might be a good behavior if we were traveling back in time to 2015, but we're far too late. For some reason I thought that it was what had been originally implemented and that it had regressed. Apologies for not doing my research when 14c7fa269e4 was under development. Let's return to the behavior we've had since 2015: always act on extensions.* settings, regardless of repository format version. While we're here, include some tests to describe the effect on the "upgrade repository version" code path.

2020-07-15commit-graph: fix "Collecting commits from input" progress lineLibravatar SZEDER Gábor1-3/+1
To display a progress line while reading commits from standard input and looking them up, 5b6653e523 (builtin/commit-graph.c: dereference tags in builtin, 2020-05-13) should have added a pair of start_delayed_progress() and stop_progress() calls around the loop reading stdin. Alas, the stop_progress() call ended up at the wrong place, after write_commit_graph(), which does all the commit-graph computation and writing, and has several progress lines of its own. Consequently, that new Collecting commits from input: 1234 progress line is overwritten by the first progress line shown by write_commit_graph(), and its final "done" line is shown last, after everything is finished: $ { sleep 3 ; git rev-list -3 HEAD ; sleep 1 ; } | ~/src/git/git commit-graph write --stdin-commits Expanding reachable commits in commit graph: 873402, done. Writing out commit graph in 4 passes: 100% (3493608/3493608), done. Collecting commits from input: 3, done. Furthermore, that stop_progress() call was added after the 'cleanup' label, where that loop reading stdin jumps in case of an error. In case of invalid input this then results in the "done" line shown after the error message: $ { sleep 3 ; git rev-list -3 HEAD ; echo junk ; } | ~/src/git/git commit-graph write --stdin-commits error: unexpected non-hex object ID: junk Collecting commits from input: 3, done. Move that stop_progress() call to the right place. While at it, drop the unnecessary 'if (progress)' condition protecting the stop_progress() call, because that function is prepared to handle a NULL progress struct.

2020-07-13git-diff.txt: reorder possible usagesLibravatar Martin Ågren1-6/+7
The description of `git diff` goes through several different invocations (numbering added by me): 1. git diff [<options>] [--] [<path>...] 2. git diff [<options>] --no-index [--] <path> <path> 3. git diff [<options>] --cached [<commit>] [--] [<path>...] 4. git diff [<options>] <commit> [--] [<path>...] 5. git diff [<options>] <commit> <commit> [--] [<path>...] 6. git diff [<options>] <commit>..<commit> [--] [<path>...] 7. git diff [<options>] <commit> <commit>... <commit> [--] [<path>...] 8. git diff [<options>] <commit>...<commit> [--] [<path>...] It then goes on to say that "all of the <commit> in the above description, except in the last two forms that use '..' notations, can be any <tree>". The "last two" actually refers to 6 and 8. This got out of sync in commit b7e10b2ca2 ("Documentation: usage for diff combined commits", 2020-06-12) which added item 7 to the mix. As a further complication, after b7e10b2ca2 we also have some potential confusion around "the '..' notation". The "..[.]" in items 6 and 8 are part of the rev notation, whereas the "..." in item 7 is manpage language for "one or more". Move item 6 down, i.e., to between 7 and 8, to restore the ordering. Because 6 refers to 5 ("synonymous to the previous form") we need to tweak the language a bit. An added bonus of this commit is that we're trying to steer users away from `git diff <commit>..<commit>` and moving it further down probably doesn't hurt.

2020-07-13git-diff.txt: don't mark required argument as optionalLibravatar Martin Ågren1-1/+1
Commit b7e10b2ca2 ("Documentation: usage for diff combined commits", 2020-06-12) modified the synopsis by adding an optional "[<commit>...]" to 'git diff' [<options>] <commit> <commit> [--] [<path>...] to effectively add 'git diff' [<options>] <commit> <commit>... <commit> [--] [<path>...] as another valid invocation. Which makes sense. Further down, in the description, it left the existing entry for 'git diff' [<options>] <commit> <commit> [--] [<path>...] intact and added a new entry on 'git diff' [<options>] <commit> [<commit>...] <commit> [--] [<path>...] where it says that "[t]his form is to view the results of a merge commit" and details how "the first listed commit must be the merge itself". But one possible instantiation of this form is `git diff <commit> <commit>` for which the added text doesn't really apply. Remove the brackets so that we lose this overlap between the two descriptions. We can still use the more compact representation in the synopsis.
