2021-04-14*: remove 'const' qualifier for struct index_stateLibravatar Derrick Stolee1-5/+5
Several methods specify that they take a 'struct index_state' pointer with the 'const' qualifier because they intend to only query the data, not change it. However, we will be introducing a step very low in the method stack that might modify a sparse-index to become a full index in the case that our queries venture inside a sparse-directory entry. This change only removes the 'const' qualifiers that are necessary for the following change which will actually modify the implementation of index_name_stage_pos().

2021-03-30sparse-checkout: disable sparse-indexLibravatar Derrick Stolee1-1/+9
We use 'git sparse-checkout init --cone --sparse-index' to toggle the sparse-index feature. It makes sense to also disable it when running 'git sparse-checkout disable'. This is particularly important because it removes the extensions.sparseIndex config option, allowing other tools to use this Git repository again. This does mean that 'git sparse-checkout init' will not re-enable the sparse-index feature, even if it was previously enabled. While testing this feature, I noticed that the sparse-index was not being written on the first run, but by a second. This was caught by the call to 'test-tool read-cache --table'. This requires adjusting some assignments to core_apply_sparse_checkout and pl.use_cone_patterns in the sparse_checkout_init() logic.

2021-03-30sparse-checkout: toggle sparse index from builtinLibravatar Derrick Stolee1-1/+16
The sparse index extension is used to signal that index writes should be in sparse mode. This was only updated using GIT_TEST_SPARSE_INDEX=1. Add a '--[no-]sparse-index' option to 'git sparse-checkout init' that specifies if the sparse index should be used. It also updates the index to use the correct format, either way. Add a warning in the documentation that the use of a repository extension might reduce compatibility with third-party tools. 'git sparse-checkout init' already sets extension.worktreeConfig, which places most sparse-checkout users outside of the scope of most third-party tools. Update t1092-sparse-checkout-compatibility.sh to use this CLI instead of GIT_TEST_SPARSE_INDEX=1.

2021-03-30sparse-checkout: hold pattern list in indexLibravatar Derrick Stolee1-7/+10
As we modify the sparse-checkout definition, we perform index operations on a pattern_list that only exists in-memory. This allows easy backing out in case the index update fails. However, if the index write itself cares about the sparse-checkout pattern set, we need access to that in-memory copy. Place a pointer to a 'struct pattern_list' in the index so we can access this on-demand. This will be used in the next change which uses the sparse-checkout definition to filter out directories that are outside the sparse cone.

2021-03-20tree.h API: simplify read_tree_recursive() signatureLibravatar Ævar Arnfjörð Bjarmason4-14/+14
Simplify the signature of read_tree_recursive() to omit the "base", "baselen" and "stage" arguments. No callers of it use these parameters for anything anymore. The last function to call read_tree_recursive() with a non-"" path was read_tree_recursive() itself, but that was changed in ffd31f661d5 (Reimplement read_tree_recursive() using tree_entry_interesting(), 2011-03-25). The last user of the "stage" parameter went away in the last commit, and even that use was mere boilerplate. So let's remove those and rename the read_tree_recursive() function to just read_tree(). We had another read_tree() function that I've refactored away in preceding commits, since all in-tree users read trees recursively with a callback we can change the name to signify that this is the norm.

Moving the rest into overlay_tree_on_index() makes this index juggling we're doing easier to read.

Now builtin/ls-files.c is the last user of this code, let's move all the relevant code there. This allows for subsequent simplification of it, and an eventual move to read_tree_recursive().

The approach to "fsck" the incoming objects in "index-pack" is attractive for performance reasons (we have them already in core, inflated and ready to be inspected), but fundamentally cannot be applied fully when we receive more than one pack stream, as a tree object in one pack may refer to a blob object in another pack as ".gitmodules", when we want to inspect blobs that are used as ".gitmodules" file, for example.

2021-02-24add: propagate --chmod errors to exit statusLibravatar Matheus Tavares1-4/+6
If `add` encounters an error while applying the --chmod changes, it prints a message to stderr, but exits with a success code. This might have been an oversight, as the command does exit with a non-zero code in other situations where it cannot (or refuses to) update all of the requested paths (e.g. when some of the given paths are ignored). So make the exit behavior more consistent by also propagating --chmod errors to the exit status. Note: the test "all statuses changed in folder if . is given" uses paths added by previous test cases, some of which might be symbolic links. Because `git add --chmod` will now fail with such paths, this test would depend on whether all the previous tests were executed, or only some of them. Avoid that by running the test on a fresh repo with only regular files.

2021-02-23push: do not turn --delete '' into a matching pushLibravatar Junio C Hamano1-1/+1

Blindly rewriting "--delete <ref>" to ":<ref>" means that an empty string <ref> results in refspec ":", which is the syntax to ask for "matching" push that does not delete anything. Worse yet, if there were matching refs that can be fast-forwarded, they would have been published prematurely, even if the user feels that they are not ready yet to be pushed out, which would be a real disaster.

2021-02-23maintenance: fix incorrect `maintenance.repo` path with bare repositoryLibravatar Eric Sunshine1-17/+33
The periodic maintenance tasks configured by `git maintenance start` invoke `git for-each-repo` to run `git maintenance run` on each path specified by the multi-value global configuration variable `maintenance.repo`. Because `git for-each-repo` will likely be run outside of the repositories which require periodic maintenance, it is mandatory that the repository paths specified by `maintenance.repo` are absolute. Unfortunately, however, `git maintenance register` does nothing to ensure that the paths it assigns to `maintenance.repo` are indeed absolute, and may in fact -- especially in the case of a bare repository -- assign a relative path to `maintenance.repo` instead. Fix this problem by converting all paths to absolute before assigning them to `maintenance.repo`. While at it, also fix `git maintenance unregister` to convert paths to absolute, as well, in order to ensure that it can correctly remove from `maintenance.repo` a path assigned via `git maintenance register`.

When `git blame --color-by-age`, the determine_line_heat() is called to select how to color the output based on the commit's author date. It uses the get_commit_info() to parse the information into a `commit_info` structure, however, this is actually unnecessary because the determine_line_heat() caller also does the same. Instead, let's change the determine_line_heat() to take a `commit_info` structure and remove the internal call to get_commit_info() thus cleaning up and optimizing the code path. Enabling Git's trace2 API in order to record the execution time for every call to determine_line_heat() function: + trace2_region_enter("blame", "determine_line_heat", the_repository); determine_line_heat(ent, &default_color); + trace2_region_enter("blame", "determine_line_heat", the_repository); Then, running `git blame` for "kernel/fork.c" in linux.git and summing all the execution time for every call (around 1.3k calls) resulted in 2.6x faster execution (best out 3): git built from 328c109303 (The eighth batch, 2021-02-12) = 42ms git built from 328c109303 + this change = 16ms Signed-off-by: Rafael Silva <rafaeloliveira.cs@gmail.com> Reviewed-by: Taylor Blau <me@ttaylorr.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2021-02-16checkout-index: omit entries with no tempname from --temp outputLibravatar Matheus Tavares1-11/+24
With --temp (or --stage=all, which implies --temp), checkout-index writes a list to stdout associating temporary file names to the entries' names. But if it fails to write an entry, and the failure happens before even assigning a temporary filename to that entry, we get an odd output line. This can be seen when trying to check out a symlink whose blob is missing: $ missing_blob=$(git hash-object --stdin </dev/null) $ git update-index --add --cacheinfo 120000,$missing_blob,foo $ git checkout-index --temp foo error: unable to read sha1 file of foo (e69de29bb2d1d6434b8b29ae775ad8c2e48c5391) foo The 'TAB foo' line is not much useful and it might break scripts that expect the 'tempname TAB foo' output. So let's omit such entries from the stdout list (but leaving the error message on stderr). We could also consider omitting _all_ failed entries from the output list, but that's probably not a good idea as the associated tempfiles may have been created even when checkout failed, so scripts may want to use the output list for cleanup.

2021-02-16diff: --{rotate,skip}-to=<path>Libravatar Junio C Hamano4-0/+7
In the implementation of "git difftool", there is a case where the user wants to start viewing the diffs at a specific path and continue on to the rest, optionally wrapping around to the beginning. Since it is somewhat cumbersome to implement such a feature as a post-processing step of "git diff" output, let's support it internally with two new options. - "git diff --rotate-to=C", when the resulting patch would show paths A B C D E without the option, would "rotate" the paths to shows patch to C D E A B instead. It is an error when there is no patch for C is shown. - "git diff --skip-to=C" would instead "skip" the paths before C, and shows patch to C D E. Again, it is an error when there is no patch for C is shown. - "git log [-p]" also accepts these two options, but it is not an error if there is no change to the specified path. Instead, the set of output paths are rotated or skipped to the specified path or the first path that sorts after the specified path. Signed-off-by: Junio C Hamano <gitster@pobox.com>
