2021-04-27hash: provide per-algorithm null OIDsLibravatar brian m. carlson1-1/+3
Up until recently, object IDs did not have an algorithm member, only a hash. Consequently, it was possible to share one null (all-zeros) object ID among all hash algorithms. Now that we're going to be handling objects from multiple hash algorithms, it's important to make sure that all object IDs have a correct algorithm field. Introduce a per-algorithm null OID, and add it to struct hash_algo. Introduce a wrapper function as well, and use it everywhere we used to use the null_oid constant.

2021-03-20tree.h API: simplify read_tree_recursive() signatureLibravatar Ævar Arnfjörð Bjarmason1-9/+9
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.

2021-03-20archive: stop passing "stage" through read_tree_recursive()Libravatar Ævar Arnfjörð Bjarmason1-9/+7
The "stage" variable being passed around in the archive code has only ever been an elaborate way to hardcode the value "0". This code was added in its original form in e4fbbfe9ecc (Add git-zip-tree, 2006-08-26), at which point a hardcoded "0" would be passed down through read_tree_recursive() to write_zip_entry(). It was then diligently added to the "struct directory" in ed22b4173bd (archive: support filtering paths with glob, 2014-09-21), but we were still not doing anything except passing it around as-is. Let's stop doing that in the code internal to archive.c, we'll still feed "0" to read_tree_recursive() itself, but won't use it. That we're providing it at all to read_tree_recursive() will be changed in a follow-up commit.

2021-03-11archive: expand only a single %(describe) per archiveLibravatar René Scharfe1-6/+10
Every %(describe) placeholder in $Format:...$ strings in files with the attribute export-subst is expanded by calling git describe. This can potentially result in a lot of such calls per archive. That's OK for local repositories under control of the user of git archive, but could be a problem for hosted repositories. Expand only a single %(describe) placeholder per archive for now to avoid denial-of-service attacks. We can make this limit configurable later if needed, but let's start out simple.

parse_treeish_arg() uses dwim_ref() to set refname to a strdup'd string. Release it after use. Also remove the const qualifier from the refname member to signify that ownership of the string is handed to the struct, leaving cleanup duty with the caller of parse_treeish_arg(), thus avoiding a cast.

2020-11-09archive: support compression levels beyond 9Libravatar René Scharfe1-15/+11
Compression programs like zip, gzip, bzip2 and xz allow to adjust the trade-off between CPU cost and size gain with numerical options from -1 for fast compression and -9 for high compression ratio. zip also accepts -0 for storing files verbatim. git archive directly support these single-digit compression levels for ZIP output and passes them to filters like gzip. Zstandard additionally supports compression level options -10 to -19, or up to -22 with --ultra. This *seems* to work with git archive in most cases, e.g. it will produce an archive with -19 without complaining, but since it only supports single-digit compression level options this is the same as -1 -9 and thus -9. Allow git archive to accept multi-digit compression levels to support the full range supported by zstd. Explicitly reject them for the ZIP format, as otherwise deflateInit2() would just fail with a somewhat cryptic "stream consistency error".

2020-09-02wt-status: tolerate dangling marksLibravatar Jonathan Tan1-2/+2
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().

2020-03-16convert: provide additional metadata to filtersLibravatar brian m. carlson1-3/+10
Now that we have the codebase wired up to pass any additional metadata to filters, let's collect the additional metadata that we'd like to pass. The two main places we pass this metadata are checkouts and archives. In these two situations, reading HEAD isn't a valid option, since HEAD isn't updated for checkouts until after the working tree is written and archives can accept an arbitrary tree. In other situations, HEAD will usually reflect the refname of the branch in current use. We pass a smaller amount of data in other cases, such as git cat-file, where we can really only logically know about the blob. This commit updates only the parts of the checkout code where we don't use unpack_trees. That function and callers of it will be handled in a future commit. In the archive code, we leak a small amount of memory, since nothing we pass in the archiver argument structure is freed.

2020-03-16convert: permit passing additional metadata to filter processesLibravatar brian m. carlson1-1/+1
There are a variety of situations where a filter process can make use of some additional metadata. For example, some people find the ident filter too limiting and would like to include the commit or the branch in their smudged files. This information isn't available during checkout as HEAD hasn't been updated at that point, and it wouldn't be available in archives either. Let's add a way to pass this metadata down to the filter. We pass the blob we're operating on, the treeish (preferring the commit over the tree if one exists), and the ref we're operating on. Note that we won't pass this information in all cases, such as when renormalizing or when we're performing diffs, since it doesn't make sense in those cases. The data we currently get from the filter process looks like the following: command=smudge pathname=git.c 0000 With this change, we'll get data more like this: command=smudge pathname=git.c refname=refs/tags/v2.25.1 treeish=c522f061d551c9bb8684a7c3859b2ece4499b56b blob=7be7ad34bd053884ec48923706e70c81719a8660 0000 There are a couple things to note about this approach. For operations like checkout, treeish will always be a commit, since we cannot check out individual trees, but for other operations, like archive, we can end up operating on only a particular tree, so we'll provide only a tree as the treeish. Similar comments apply for refname, since there are a variety of cases in which we won't have a ref. This commit wires up the code to print this information, but doesn't pass any of it at this point. In a future commit, we'll have various code paths pass the actual useful data down. Signed-off-by: brian m. carlson <bk2204@github.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

"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

2018-10-26archive: initialize archivers earlierLibravatar Josh Steadmon1-3/+6
Initialize archivers as soon as possible when running git-archive. Various non-obvious behavior depends on having the archivers initialized, such as determining the desired archival format from the provided filename. Since 08716b3c11 ("archive: refactor file extension format-guessing", 2011-06-21), archive_format_from_filename() has used the registered archivers to match filenames (provided via --output) to archival formats. However, when git-archive is executed with --remote, format detection happens before the archivers have been registered. This causes archives from remotes to always be generated as TAR files, regardless of the actual filename (unless an explicit --format is provided). This patch fixes that behavior; archival format is determined properly from the output filename, even when --remote is used.

Since attr checking API now take the index, there's no need to set an index in advance with this call. Most call sites are straightforward because they either pass the_index or NULL (which defaults back to the_index previously).

This code in unpack-trees is about to check out entries from the new/temporary index after merging is done in it.

Make the attr API take an index_state instead of assuming the_index in attr code. All call sites are converted blindly to keep the patch simple and retain current behavior. Individual call sites may receive further updates to use the right index instead of the_index. There is one ugly temporary workaround added in attr.c that needs some more explanation. Commit c24f3abace (apply: file commited with CRLF should roundtrip diff and apply - 2017-08-19) forces one convert_to_git() call to NOT read the index at all. But what do you know, we read it anyway by falling back to the_index. When "istate" from convert_to_git is now propagated down to read_attr_from_array() we will hit segfault somewhere inside read_blob_data_from_index. The right way of dealing with this is to kill "use_index" variable and only follow "istate" but at this stage we are not ready for that: while most git_attr_set_direction() calls just passes the_index to be assigned to use_index, unpack-trees passes a different one which is used by entry.c code, which has no way to know what index to use if we delete use_index.

"git archive", especially when used with pathspec, stored an empty directory in its output, even though Git itself never does so. This has been fixed. * rs/archive-excluded-directory: archive: don't add empty directories to archives
2017-09-14archive: don't add empty directories to archivesLibravatar René Scharfe1-17/+2
While git doesn't track empty directories, git archive can be tricked into putting some into archives. One way is to construct an empty tree object, as t5004 does. While that is supported by the object database, it can't be represented in the index and thus it's unlikely to occur in the wild. Another way is using the literal name of a directory in an exclude pathspec -- its contents are are excluded, but the directory stub is included. That's inconsistent: exclude pathspecs containing wildcards don't leave empty directories in the archive. Yet another way is have a few levels of nested subdirectories (e.g. d1/d2/d3/file1) and ignoring the entries at the leaves (e.g. file1). The directories with the ignored content are ignored as well (e.g. d3), but their empty parents are included (e.g. d2). As empty directories are not supported by git, they should also not be written into archives. If an empty directory is really needed then it can be tracked and archived by placing an empty .gitignore file in it. There already is a mechanism in place for suppressing empty directories. When read_tree_recursive() encounters a directory excluded by a pathspec then it enters it anyway because it might contain included entries. It calls the callback function before it is able to decide if the directory is actually needed. For that reason git archive adds directories to a queue and writes entries for them only when it encounters the first child item -- but currently only if pathspecs with wildcards are used. Queue *all* directories, no matter if there even are pathspecs present. This prevents git archive from writing entries for empty directories in all cases.

"git archive" did not work well with pathspecs and the export-ignore attribute. * rs/archive-excluded-directory: archive: don't queue excluded directories archive: factor out helper functions for handling attributes t5001: add tests for export-ignore attributes and exclude pathspecs
2017-08-19archive: don't queue excluded directoriesLibravatar René Scharfe1-7/+25
Reject directories with the attribute export-ignore already while queuing them. This prevents read_tree_recursive() from descending into them and this avoids write_archive_entry() rejecting them later on, which queue_or_write_archive_entry() is not prepared for. Borrow the existing strbuf to build the full path to avoid string copies and extra allocations; just make sure we restore the original value before moving on. Keep checking any other attributes in write_archive_entry() as before, but avoid checking them twice. Signed-off-by: Rene Scharfe <l.s.r@web.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2017-07-17sha1_name: convert get_sha1* to get_oid*Libravatar brian m. carlson1-1/+1
Now that all the callers of get_sha1 directly or indirectly use struct object_id, rename the functions starting with get_sha1 to start with get_oid. Convert the internals in sha1_name.c to use struct object_id as well, and eliminate explicit length checks where possible. Convert a use of 40 in get_oid_basic to GIT_SHA1_HEXSZ. Outside of sha1_name.c and cache.h, this transition was made with the following semantic patch: @@ expression E1, E2; @@ - get_sha1(E1, E2.hash) + get_oid(E1, &E2) @@ expression E1, E2; @@ - get_sha1(E1, E2->hash) + get_oid(E1, E2) @@ expression E1, E2; @@ - get_sha1_committish(E1, E2.hash) + get_oid_committish(E1, &E2) @@ expression E1, E2; @@ - get_sha1_committish(E1, E2->hash) + get_oid_committish(E1, E2) @@ expression E1, E2; @@ - get_sha1_treeish(E1, E2.hash) + get_oid_treeish(E1, &E2) @@ expression E1, E2; @@ - get_sha1_treeish(E1, E2->hash) + get_oid_treeish(E1, E2) @@ expression E1, E2; @@ - get_sha1_commit(E1, E2.hash) + get_oid_commit(E1, &E2) @@ expression E1, E2; @@ - get_sha1_commit(E1, E2->hash) + get_oid_commit(E1, E2) @@ expression E1, E2; @@ - get_sha1_tree(E1, E2.hash) + get_oid_tree(E1, &E2) @@ expression E1, E2; @@ - get_sha1_tree(E1, E2->hash) + get_oid_tree(E1, E2) @@ expression E1, E2; @@ - get_sha1_blob(E1, E2.hash) + get_oid_blob(E1, &E2) @@ expression E1, E2; @@ - get_sha1_blob(E1, E2->hash) + get_oid_blob(E1, E2) @@ expression E1, E2, E3, E4; @@ - get_sha1_with_context(E1, E2, E3.hash, E4) + get_oid_with_context(E1, E2, &E3, E4) @@ expression E1, E2, E3, E4; @@ - get_sha1_with_context(E1, E2, E3->hash, E4) + get_oid_with_context(E1, E2, E3, E4) Signed-off-by: brian m. carlson <sandals@crustytoothpaste.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
