2021-09-27refs: drop "broken" flag from for_each_fullref_in()Jeff King
No callers pass in anything but "0" here. Likewise to our sibling functions. Note that some of them ferry along the flag, but none of their callers pass anything but "0" either. Nor is anybody likely to change that. Callers which really want to see all of the raw refs use for_each_rawref(). And anybody interested in iterating a subset of the refs will likely be happy to use the now-default behavior of showing broken refs, but omitting dangling symlinks. So we can get rid of this whole feature. Signed-off-by: Jeff King <peff@peff.net> Reviewed-by: Jonathan Tan <jonathantanmy@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2021-05-17rev-parse: fix segfault with missing --path-format argumentWolfgang Müller
Calling "git rev-parse --path-format" without an argument segfaults instead of giving an error message. Commit fac60b8925 (rev-parse: add option for absolute or relative path formatting, 2020-12-13) added the argument parsing code but forgot to handle NULL. Returning an error makes sense here because there is no default value we could use. Add a test case to verify.

2020-12-13rev-parse: add option for absolute or relative path formattingbrian m. carlson
git rev-parse has several options which print various paths. Some of these paths are printed relative to the current working directory, and some are absolute. Normally, this is not a problem, but there are times when one wants paths entirely in one format or another. This can be done trivially if the paths are canonical, but canonicalizing paths is not possible on some shell scripting environments which lack realpath(1) and also in Go, which lacks functions that properly canonicalize paths on Windows. To help out the scripter, let's provide an option which turns most of the paths printed by git rev-parse to be either relative to the current working directory or absolute and canonical. Document which options are affected and which are not so that users are not confused. This approach is cleaner and tidier than providing duplicates of existing options which are either relative or absolute. Note that if the user needs both forms, it is possible to pass an additional option in the middle of the command line which changes the behavior of subsequent operations.

2020-11-10rev-parse: handle --end-of-optionsJeff King
We taught rev-list a new way to separate options from revisions in 19e8789b23 (revision: allow --end-of-options to end option parsing, 2019-08-06), but rev-parse uses its own parser. It should know about --end-of-options not only for consistency, but because it may be presented with similarly ambiguous cases. E.g., if a caller does: git rev-parse "$rev" -- "$path" to parse an untrusted input, then it will get confused if $rev contains an option-like string like "--local-env-vars". Or even "--not-real", which we'd keep as an option to pass along to rev-list. Or even more importantly: git rev-parse --verify "$rev" can be confused by options, even though its purpose is safely parsing untrusted input. On the plus side, it will always fail the --verify part, as it will not have parsed a revision, so the caller will generally "fail closed" rather than continue to use the untrusted string. But it will still trigger whatever option was in "$rev"; this should be mostly harmless, since rev-parse options are all read-only, but I didn't carefully audit all paths. This patch lets callers write: git rev-parse --end-of-options "$rev" -- "$path" and: git rev-parse --verify --end-of-options "$rev" which will both treat "$rev" always as a revision parameter. The latter is a bit clunky. It would be nicer if we had defined "--verify" to require that its next argument be the revision. But we have not historically done so, and: git rev-parse --verify -q "$rev" does currently work. I added a test here to confirm that we didn't break that. A few implementation notes: - We don't document --end-of-options explicitly in commands, but rather in gitcli(7). So I didn't give it its own section in git-rev-parse(1). But I did call it out specifically in the --verify section, and include it in the examples, which should show best practices. - We don't have to re-indent the main option-parsing block, because we can combine our "did we see end of options" check with "does it start with a dash". The exception is the pre-setup options, which need their own block. - We do however have to pull the "--" parsing out of the "does it start with dash" block, because we want to parse it even if we've seen --end-of-options. - We'll leave "--end-of-options" in the output. This is probably not technically necessary, as a careful caller will do: git rev-parse --end-of-options $revs -- $paths and anything in $revs will be resolved to an object id. However, it does help a slightly less careful caller like: git rev-parse --end-of-options $revs_or_paths where a path "--foo" will remain in the output as long as it also exists on disk. In that case, it's helpful to retain --end-of-options to get passed along to rev-list, s it would otherwise see just "--foo".

2020-11-10rev-parse: put all options under the "-" checkJeff King
The option-parsing loop of rev-parse checks whether the first character of an arg is "-". If so, then it enters a series of conditionals checking for individual options. But some options are inexplicably outside of that outer conditional. This doesn't produce the wrong behavior; the conditional is actually redundant with the individual option checks, and it's really only its fallback "continue" that we care about. But we should at least be consistent. One obvious alternative is that we could get rid of the conditional entirely. But we'll be using the extra block it provides in the next patch.

2020-11-10rev-parse: don't accept options after dashdashJeff King
Because of the order in which we check options in rev-parse, there are a few options we accept even after a "--". This is wrong, because the whole point of "--" is to say "everything after here is a path". Let's move the "did we see a dashdash" check (it's called "as_is" in the code) to the top of the parsing loop. Note there is one subtlety here. The options are ordered so that some are checked before we even see if we're in a repository (they continue the loop, and if we get past a certain point, then we do the repository setup). By moving the as_is check higher, it's also in that "before setup" section, even though it might look at the repository via verify_filename(). However, this works out: we'd never set as_is until we parse "--", and we don't parse that until after doing the setup. An alternative here to avoid the subtlety is to put the as_is check at the top of the post-setup options. But then every pre-setup option would have to remember to check "if (!as_is && !strcmp(...))". So while this is a bit magical, it's harder for future code to get wrong.

2020-09-02wt-status: tolerate dangling marksJonathan Tan
When a user checks out the upstream branch of HEAD, the upstream branch not being a local branch, and then runs "git status", like this: git clone $URL client cd client git checkout @{u} git status no status is printed, but instead an error message: fatal: HEAD does not point to a branch (This error message when running "git branch" persists even after checking out other things - it only stops after checking out a branch.) This is because "git status" reads the reflog when determining the "HEAD detached" message, and thus attempts to DWIM "@{u}", but that doesn't work because HEAD no longer points to a branch. Therefore, when calculating the status of a worktree, tolerate dangling marks. This is done by adding an additional parameter to dwim_ref() and repo_dwim_ref().

2020-04-30shallow: extract a header file for shallow-related functionsTaylor Blau
There are many functions in commit.h that are more related to shallow repositories than they are to any sort of generic commit machinery. Likely this began when there were only a few shallow-related functions, and commit.h seemed a reasonable enough place to put them. But, now there are a good number of shallow-related functions, and placing them all in 'commit.h' doesn't make sense. This patch extracts a 'shallow.h', which takes all of the declarations from 'commit.h' for functions which already exist in 'shallow.c'. We will bring the remaining shallow-related functions defined in 'commit.c' in a subsequent patch. For now, move only the ones that already are implemented in 'shallow.c', and update the necessary includes.

Returning a shared buffer invites very subtle bugs due to reentrancy or multi-threading, as demonstrated by the previous patch. There was an unfinished effort to abolish this [1]. Let's finally rid of `real_path()`, using `strbuf_realpath()` instead. This patch uses a local `strbuf` for most places where `real_path()` was previously called. However, two places return the value of `real_path()` to the caller. For them, a `static` local `strbuf` was added, effectively pushing the problem one level higher: read_gitfile_gently() get_superproject_working_tree() [1] https://lore.kernel.org/git/1480964316-99305-1-git-send-email-bmwill@google.com/ Signed-off-by: Alexandr Miloslavskiy <alexandr.miloslavskiy@syntevo.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2019-11-20rev-parse: make --show-toplevel without a worktree an errorJeff King
Ever since it was introduced in 7cceca5ccc (Add 'git rev-parse --show-toplevel' option., 2010-01-12), the --show-toplevel option has treated a missing working tree as a quiet success: it neither prints a toplevel path, but nor does it report any kind of error. While a caller could distinguish this case by looking for an empty response, the behavior is rather confusing. We're better off complaining that there is no working tree, as other internal commands would do in similar cases (e.g., "git status" or any builtin with NEED_WORK_TREE set would just die()). So let's do the same here. While we're at it, let's clarify the documentation and add some tests, both for the new behavior and for the more mundane case (which was not covered).

2017-05-08Convert lookup_commit* to struct object_idbrian m. carlson
Convert lookup_commit, lookup_commit_or_die, lookup_commit_reference, and lookup_commit_reference_gently to take struct object_id arguments. Introduce a temporary in parse_object buffer in order to convert this function. This is required since in order to convert parse_object and parse_object_buffer, lookup_commit_reference_gently and lookup_commit_or_die would need to be converted. Not introducing a temporary would therefore require that lookup_commit_or_die take a struct object_id *, but lookup_commit would take unsigned char *, leaving a confusing and hard-to-use interface. parse_object_buffer will lose this temporary in a later patch. This commit was created with manual changes to commit.c, commit.h, and object.c, plus the following semantic patch: @@ expression E1, E2; @@ - lookup_commit_reference_gently(E1.hash, E2) + lookup_commit_reference_gently(&E1, E2) @@ expression E1, E2; @@ - lookup_commit_reference_gently(E1->hash, E2) + lookup_commit_reference_gently(E1, E2) @@ expression E1; @@ - lookup_commit_reference(E1.hash) + lookup_commit_reference(&E1) @@ expression E1; @@ - lookup_commit_reference(E1->hash) + lookup_commit_reference(E1) @@ expression E1; @@ - lookup_commit(E1.hash) + lookup_commit(&E1) @@ expression E1; @@ - lookup_commit(E1->hash) + lookup_commit(E1) @@ expression E1, E2; @@ - lookup_commit_or_die(E1.hash, E2) + lookup_commit_or_die(&E1, E2) @@ expression E1, E2; @@ - lookup_commit_or_die(E1->hash, E2) + lookup_commit_or_die(E1, E2) Signed-off-by: brian m. carlson <sandals@crustytoothpaste.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2017-04-24PRItime: introduce a new "printf format" for timestampsJohannes Schindelin
Currently, Git's source code treats all timestamps as if they were unsigned longs. Therefore, it is okay to write "%lu" when printing them. There is a substantial problem with that, though: at least on Windows, time_t is *larger* than unsigned long, and hence we will want to switch away from the ill-specified `unsigned long` data type. So let's introduce the pseudo format "PRItime" (currently simply being defined to "lu") to make it easier to change the data type used for timestamps.
