2020-04-28Use OPT_CALLBACK and OPT_CALLBACK_FDenton Liu
In the codebase, there are many options which use OPTION_CALLBACK in a plain ol' struct definition. However, we have the OPT_CALLBACK and OPT_CALLBACK_F macros which are meant to abstract these plain struct definitions away. These macros are useful as they semantically signal to developers that these are just normal callback option with nothing fancy happening. Replace plain struct definitions of OPTION_CALLBACK with OPT_CALLBACK or OPT_CALLBACK_F where applicable. The heavy lifting was done using the following (disgusting) shell script: #!/bin/sh do_replacement () { tr '\n' '\r' | sed -e 's/{\s*OPTION_CALLBACK,\s*\([^,]*\),\([^,]*\),\([^,]*\),\([^,]*\),\([^,]*\),\s*0,\(\s*[^[:space:]}]*\)\s*}/OPT_CALLBACK(\1,\2,\3,\4,\5,\6)/g' | sed -e 's/{\s*OPTION_CALLBACK,\s*\([^,]*\),\([^,]*\),\([^,]*\),\([^,]*\),\([^,]*\),\([^,]*\),\(\s*[^[:space:]}]*\)\s*}/OPT_CALLBACK_F(\1,\2,\3,\4,\5,\6,\7)/g' | tr '\r' '\n' } for f in $(git ls-files \*.c) do do_replacement <"$f" >"$f.tmp" mv "$f.tmp" "$f" done The result was manually inspected and then reformatted to match the style of the surrounding code. Finally, using `git grep OPTION_CALLBACK \*.c`, leftover results which were not handled by the script were manually transformed.

"git stash save" in a working tree that is sparsely checked out mistakenly removed paths that are outside the area of interest. * js/update-index-ignore-removal-for-skip-worktree: stash: handle staged changes in skip-worktree files correctly update-index: optionally leave skip-worktree entries alone
2019-11-02update-index: optionally leave skip-worktree entries aloneJohannes Schindelin
While `git update-index` mostly ignores paths referring to index entries whose skip-worktree bit is set, in b4d1690df11 (Teach Git to respect skip-worktree bit (reading part), 2009-08-20), for reasons that are not entirely obvious, the `--remove` option was made special: it _does_ remove index entries even if their skip-worktree bit is set. Seeing as this behavior has been in place for a decade now, it does not make sense to change it. However, in preparation for fixing a bug in `git stash` where it pretends that skip-worktree entries have actually been removed, we need a mode where `git update-index` leaves all skip-worktree entries alone, even if the `--remove` option was passed.

2019-08-13repo-settings: parse core.untrackedCacheDerrick Stolee
The core.untrackedCache config setting is slightly complicated, so clarify its use and centralize its parsing into the repo settings. The default value is "keep" (returned as -1), which persists the untracked cache if it exists. If the value is set as "false" (returned as 0), then remove the untracked cache if it exists. If the value is set as "true" (returned as 1), then write the untracked cache and persist it. Instead of relying on magic values of -1, 0, and 1, split these options into an enum. This allows the use of "-1" as a default value. After parsing the config options, if the value is unset we can initialize it to UNTRACKED_CACHE_KEEP.

2019-05-08Merge branch 'en/merge-directory-renames'Junio C Hamano
"git merge-recursive" backend recently learned a new heuristics to infer file movement based on how other files in the same directory moved. As this is inherently less robust heuristics than the one based on the content similarity of the file itself (rather than based on what its neighbours are doing), it sometimes gives an outcome unexpected by the end users. This has been toned down to leave the renamed paths in higher/conflicted stages in the index so that the user can examine and confirm the result. * en/merge-directory-renames: merge-recursive: switch directory rename detection default merge-recursive: give callers of handle_content_merge() access to contents merge-recursive: track information associated with directory renames t6043: fix copied test description to match its purpose merge-recursive: switch from (oid,mode) pairs to a diff_filespec merge-recursive: cleanup handle_rename_* function signatures merge-recursive: track branch where rename occurred in rename struct merge-recursive: remove ren[12]_other fields from rename_conflict_info merge-recursive: shrink rename_conflict_info merge-recursive: move some struct declarations together merge-recursive: use 'ci' for rename_conflict_info variable name merge-recursive: rename locals 'o' and 'a' to 'obuf' and 'abuf' merge-recursive: rename diff_filespec 'one' to 'o' merge-recursive: rename merge_options argument from 'o' to 'opt' Use 'unsigned short' for mode, like diff_filespec does

OPTION_CALLBACK is much simpler/safer to use, but parse_opt_cb does not allow access to parse_opt_ctx_t, which sometimes is useful (e.g. to obtain the prefix). Extending parse_opt_cb to take parse_opt_cb could result in a lot of changes. Instead let's just allow ll_callback to be used with OPTION_CALLBACK.

2018-11-06assert NOARG/NONEG behavior of parse-options callbacksJeff King
When we define a parse-options callback, the flags we put in the option struct must match what the callback expects. For example, a callback which does not handle the "unset" parameter should only be used with PARSE_OPT_NONEG. But since the callback and the option struct are not defined next to each other, it's easy to get this wrong (as earlier patches in this series show). Fortunately, the compiler can help us here: compiling with -Wunused-parameters can show us which callbacks ignore their "unset" parameters (and likewise, ones that ignore "arg" expect to be triggered with PARSE_OPT_NOARG). But after we've inspected a callback and determined that all of its callers use the right flags, what do we do next? We'd like to silence the compiler warning, but do so in a way that will catch any wrong calls in the future. We can do that by actually checking those variables and asserting that they match our expectations. Because this is such a common pattern, we'll introduce some helper macros. The resulting messages aren't as descriptive as we could make them, but the file/line information from BUG() is enough to identify the problem (and anyway, the point is that these should never be seen). Each of the annotated callbacks in this patch triggers -Wunused-parameters, and was manually inspected to make sure all callers use the correct options (so none of these BUGs should be triggerable).

2018-08-29convert "oidcmp() == 0" to oideq()Jeff King
Using the more restrictive oideq() should, in the long run, give the compiler more opportunities to optimize these callsites. For now, this conversion should be a complete noop with respect to the generated code. The result is also perhaps a little more readable, as it avoids the "zero is equal" idiom. Since it's so prevalent in C, I think seasoned programmers tend not to even notice it anymore, but it can sometimes make for awkward double negations (e.g., we can drop a few !!oidcmp() instances here). This patch was generated almost entirely by the included coccinelle patch. This mechanical conversion should be completely safe, because we check explicitly for cases where oidcmp() is compared to 0, which is what oideq() is doing under the hood. Note that we don't have to catch "!oidcmp()" separately; coccinelle's standard isomorphisms make sure the two are treated equivalently. I say "almost" because I did hand-edit the coccinelle output to fix up a few style violations (it mostly keeps the original formatting, but sometimes unwraps long lines).

Parseopt wraps argument help strings in a pair of angular brackets by default, to tell users that they need to replace it with an actual value. This is useful in most cases, because most option arguments are indeed single values of a certain type. The option PARSE_OPT_LITERAL_ARGHELP needs to be used in option definitions with arguments that have multiple parts or are literal strings. Stop adding these angular brackets if special characters are present, as they indicate that we don't deal with a simple placeholder.

2018-07-03block alloc: add lifecycle APIs for cache_entry structsJameson Miller
It has been observed that the time spent loading an index with a large number of entries is partly dominated by malloc() calls. This change is in preparation for using memory pools to reduce the number of malloc() calls made to allocate cahce entries when loading an index. Add an API to allocate and discard cache entries, abstracting the details of managing the memory backing the cache entries. This commit does actually change how memory is managed - this will be done in a later commit in the series. This change makes the distinction between cache entries that are associated with an index and cache entries that are not associated with an index. A main use of cache entries is with an index, and we can optimize the memory management around this. We still have other cases where a cache entry is not persisted with an index, and so we need to handle the "transient" use case as well. To keep the congnitive overhead of managing the cache entries, there will only be a single discard function. This means there must be enough information kept with the cache entry so that we know how to discard them. A summary of the main functions in the API is: make_cache_entry: create cache entry for use in an index. Uses specified parameters to populate cache_entry fields. make_empty_cache_entry: Create an empty cache entry for use in an index. Returns cache entry with empty fields. make_transient_cache_entry: create cache entry that is not used in an index. Uses specified parameters to populate cache_entry fields. make_empty_transient_cache_entry: create cache entry that is not used in an index. Returns cache entry with empty fields. discard_cache_entry: A single function that knows how to discard a cache entry regardless of how it was allocated.

2018-05-22verify_path: disallow symlinks in .gitmodulesJeff King
There are a few reasons it's not a good idea to make .gitmodules a symlink, including: 1. It won't be portable to systems without symlinks. 2. It may behave inconsistently, since Git may look at this file in the index or a tree without bothering to resolve any symbolic links. We don't do this _yet_, but the config infrastructure is there and it's planned for the future. With some clever code, we could make (2) work. And some people may not care about (1) if they only work on one platform. But there are a few security reasons to simply disallow it: a. A symlinked .gitmodules file may circumvent any fsck checks of the content. b. Git may read and write from the on-disk file without sanity checking the symlink target. So for example, if you link ".gitmodules" to "../oops" and run "git submodule add", we'll write to the file "oops" outside the repository. Again, both of those are problems that _could_ be solved with sufficient code, but given the complications in (1) and (2), we're better off just outlawing it explicitly. Note the slightly tricky call to verify_path() in update-index's update_one(). There we may not have a mode if we're not updating from the filesystem (e.g., we might just be removing the file). Passing "0" as the mode there works fine; since it's not a symlink, we'll just skip the extra checks. Signed-off-by: Jeff King <peff@peff.net>
2018-05-22update-index: stat updated files earlierJeff King
In the update_one(), we check verify_path() on the proposed path before doing anything else. In preparation for having verify_path() look at the file mode, let's stat the file earlier, so we can check the mode accurately. This is made a bit trickier by the fact that this function only does an lstat in a few code paths (the ones that flow down through process_path()). So we can speculatively do the lstat() here and pass the results down, and just use a dummy mode for cases where we won't actually be updating the index from the filesystem.

2018-05-06Replace all die("BUG: ...") calls by BUG() onesJohannes Schindelin
In d8193743e08 (usage.c: add BUG() function, 2017-05-12), a new macro was introduced to use for reporting bugs instead of die(). It was then subsequently used to convert one single caller in 588a538ae55 (setup_git_env: convert die("BUG") to BUG(), 2017-05-12). The cover letter of the patch series containing this patch (cf 20170513032414.mfrwabt4hovujde2@sigill.intra.peff.net) is not terribly clear why only one call site was converted, or what the plan is for other, similar calls to die() to report bugs. Let's just convert all remaining ones in one fell swoop. This trick was performed by this invocation: sed -i 's/die("BUG: /BUG("/g' $(git grep -l 'die("BUG' \*.c) Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>

"git tag --contains no-such-commit" gave a full list of options after giving an error message. * ps/contains-id-error-message: parse-options: do not show usage upon invalid option value
2018-03-22parse-options: do not show usage upon invalid option valuePaul-Sebastian Ungureanu
Usually, the usage should be shown only if the user does not know what options are available. If the user specifies an invalid value, the user is already aware of the available options. In this case, there is no point in displaying the usage anymore. This patch applies to "git tag --contains", "git branch --contains", "git branch --points-at", "git for-each-ref --contains" and many more.
