2022-03-14stash: make internal resets quiet and refresh indexLibravatar Victoria Dye2-2/+36
Add the options '-q' and '--refresh' to the 'git reset' executed in 'reset_head()', and '--refresh' to the 'git reset -q' executed in 'do_push_stash(...)'. 'stash' is implemented such that git commands invoked as part of it (e.g., 'clean', 'read-tree', 'reset', etc.) have their informational output silenced. However, the 'reset' in 'reset_head()' is *not* called with '-q', leading to the potential for a misleading printout from 'git stash apply --index' if the stash included a removed file: Unstaged changes after reset: D <deleted file> Not only is this confusing in its own right (since, after the reset, 'git stash' execution would stage the deletion in the index), it would be printed even when the stash was applied with the '-q' option. As a result, the messaging is removed entirely by calling 'git status' with '-q'. Additionally, because the default behavior of 'git reset -q' is to skip refreshing the index, but later operations in 'git stash' subcommands expect a non-stale index, enable '--refresh' as well.

2022-03-14reset: replace '--quiet' with '--no-refresh' in performance adviceLibravatar Victoria Dye4-10/+10
Replace references to '--quiet' with '--no-refresh' in the advice on how to skip refreshing the index. When the advice was introduced, '--quiet' was the only way to avoid the expensive 'refresh_index(...)' at the end of a mixed reset. After introducing '--no-refresh', however, '--quiet' became only a fallback option for determining refresh behavior, overridden by '--[no-]refresh' or 'reset.refresh' if either is set. To ensure users are advised to use the most reliable option for avoiding 'refresh_index(...)', replace recommendation of '--quiet' with '--[no-]refresh'.

2022-03-14reset: introduce --[no-]refresh option to --mixedLibravatar Victoria Dye3-8/+87
Add a new --[no-]refresh option that is intended to explicitly determine whether a mixed reset should end in an index refresh. Starting at 9ac8125d1a (reset: don't compute unstaged changes after reset when --quiet, 2018-10-23), using the '--quiet' option results in skipping the call to 'refresh_index(...)' at the end of a mixed reset with the goal of improving performance. However, by coupling behavior that modifies the index with the option that silences logs, there is no way for users to have one without the other (i.e., silenced logs with a refreshed index) without incurring the overhead of a separate call to 'git update-index --refresh'. Furthermore, there is minimal user-facing documentation indicating that --quiet skips the index refresh, potentially leading to unexpected issues executing commands after 'git reset --quiet' that do not themselves refresh the index (e.g., internals of 'git stash', 'git read-tree'). To mitigate these issues, '--[no-]refresh' and 'reset.refresh' are introduced to provide a dedicated mechanism for refreshing the index. When either is set, '--quiet' and 'reset.quiet' revert to controlling only whether logs are silenced and do not affect index refresh.

2022-03-14reset: revise index refresh adviceLibravatar Victoria Dye2-4/+4
Update the advice describing index refresh from "enumerate unstaged changes" to "refresh the index." Describing 'refresh_index(...)' as "enumerating unstaged changes" is not fully representative of what an index refresh is doing; more generally, it updates the properties of index entries that are affected by outside-of-index state, e.g. CE_UPTODATE, which is affected by the file contents on-disk. This distinction is relevant to operations that read the index but do not refresh first - e.g., 'git read-tree' - where a stale index may cause incorrect behavior. In addition to changing the advice message, use the "advise" function to print advice. Signed-off-by: Victoria Dye <vdye@github.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2022-03-01repo_read_index: add config to expect files outside sparse patternsLibravatar Elijah Newren7-1/+66
Typically with sparse checkouts, we expect files outside the sparsity patterns to be marked as SKIP_WORKTREE and be missing from the working tree. Sometimes this expectation would be violated however; including in cases such as: * users grabbing files from elsewhere and writing them to the worktree (perhaps by editing a cached copy in an editor, copying/renaming, or even untarring) * various git commands having incomplete or no support for the SKIP_WORKTREE bit[1,2] * users attempting to "abort" a sparse-checkout operation with a not-so-early Ctrl+C (updating $GIT_DIR/info/sparse-checkout and the working tree is not atomic)[3]. When the SKIP_WORKTREE bit in the index did not reflect the presence of the file in the working tree, it traditionally caused confusion and was difficult to detect and recover from. So, in a sparse checkout, since af6a51875a (repo_read_index: clear SKIP_WORKTREE bit from files present in worktree, 2022-01-14), Git automatically clears the SKIP_WORKTREE bit at index read time for entries corresponding to files that are present in the working tree. There is another workflow, however, where it is expected that paths outside the sparsity patterns appear to exist in the working tree and that they do not lose the SKIP_WORKTREE bit, at least until they get modified. A Git-aware virtual file system[4] takes advantage of its position as a file system driver to expose all files in the working tree, fetch them on demand using partial clone on access, and tell Git to pay attention to them on demand by updating the sparse checkout pattern on writes. This means that commands like "git status" only have to examine files that have potentially been modified, whereas commands like "ls" are able to show the entire codebase without requiring manual updates to the sparse checkout pattern. Thus since af6a51875a, Git with such Git-aware virtual file systems unsets the SKIP_WORKTREE bit for all files and commands like "git status" have to fetch and examine them all. Introduce a configuration setting sparse.expectFilesOutsideOfPatterns to allow limiting the tracked set of files to a small set once again. A Git-aware virtual file system or other application that wants to maintain files outside of the sparse checkout can set this in a repository to instruct Git not to check for the presence of SKIP_WORKTREE files. The setting defaults to false, so most users of sparse checkout will still get the benefit of an automatically updating index to recover from the variety of difficult issues detailed in af6a51875a for paths with SKIP_WORKTREE set despite the path being present.

2022-02-28test-lib: correct and assert TEST_DIRECTORY overridingLibravatar Ævar Arnfjörð Bjarmason1-5/+17
Correct a misleading comment added by me in 62f539043c7 (test-lib: Allow overriding of TEST_DIRECTORY, 2010-08-19), and add an assertion that TEST_DIRECTORY cannot point to any directory except the "t" directory in the top-level of git.git. This assertion is in effect not new, since we'd already die if that wasn't the case[1], but it and the updated commentary help to make that clearer. The existing comments were also on the wrong arms of the "if". I.e. the "allow tests to override this" was on the "test -z" arm. That came about due to a combination of 62f539043c7 and 85176d72513 (test-lib.sh: convert $TEST_DIRECTORY to an absolute path, 2013-11-17). Those earlier comments could be read as allowing the "$TEST_DIRECTORY" to be some path outside of t/. As explained in the updated comment that's impossible, rather it was meant for *tests* that ran outside of t/, i.e. the "t0000-basic.sh" tests that use "lib-subtest.sh". Those tests have a different working directory, but they set the "TEST_DIRECTORY" to the same path for bootstrapping. The comments now reflect that, and further comment on why we have a hard dependency on this. 1. https://lore.kernel.org/git/220222.86o82z8als.gmgdl@evledraar.gmail.com/ Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2022-02-28test-lib: add GIT_SAN_OPTIONS, inherit [AL]SAN_OPTIONSLibravatar Ævar Arnfjörð Bjarmason1-4/+20
Change our ASAN_OPTIONS and LSAN_OPTIONS to set defaults for those variables, rather than punting out entirely if we already have them in the environment. We want to take any user-provided settings over our own, but we can do that by prepending our defaults to the variable. The libsanitizer options parsing has "last option wins" semantics. It's now possible to do e.g.: LSAN_OPTIONS=report_objects=1 ./t0006-date.sh And not have the "report_objects=1" setting overwrite our sensible default of "abort_on_error=1", but by prepending to the list we ensure that: LSAN_OPTIONS=report_objects=1:abort_on_error=0 ./t0006-date.sh Will take the desired "abort_on_error=0" over our default. See b0f4c9087e1 (t: support clang/gcc AddressSanitizer, 2014-12-08) for the original pattern being altered here, and 85b81b35ff9 (test-lib: set LSAN_OPTIONS to abort by default, 2017-09-05) for when LSAN_OPTIONS was added in addition to the then-existing ASAN_OPTIONS.

2022-02-27rerere-train: two fixes to the use of "git show -s"Libravatar Junio C Hamano1-1/+1
The script uses "git show -s" to display the title of the merge commit being studied, without explicitly disabling the pager, which is not a safe thing to do in a script. For example, when the pager is set to "less" with "-SF" options (-S tells the pager not to fold lines but allow horizontal scrolling to show the overly long lines, -F tells the pager not to wait if the output in its entirety is shown on a single page), and the title of the merge commit is longer than the width of the terminal, the pager will wait until the end-user tells it to quit after showing the single line. Explicitly disable the pager with this "git show" invocation to fix this. The command uses the "--pretty=format:..." format, which adds LF in between each pair of commits it outputs, which means that the label for the merge being learned from will be followed by the next message on the same line. "--pretty=tformat:..." is what we should instead, which adds LF after each commit, or a more modern way to spell it, i.e. "--format=...". This existing breakage becomes easier to see, now we no longer use the pager. Signed-off-by: Junio C Hamano <gitster@pobox.com>

2022-02-24fast-import.c: use designated initializers for "partial" struct assignmentsLibravatar Ævar Arnfjörð Bjarmason1-4/+10
Change a few existing non-designated initializer assignments to use "partial" designated initializer assignments. I.e. we're now omitting the "NULL" or "0" fields and letting the initializer take care of them for us.
