git/archive.c, branch v2.29.2

archive: add --add-file

2020-09-19T22:56:06Z

Allow users to append non-tracked files. This simplifies the generation of source packages with a few extra files, e.g. containing version information. They get the same access times and user information as tracked files. Signed-off-by: René Scharfe Signed-off-by: Junio C Hamano

archive: read short blobs in archive.c::write_archive_entry()

2020-09-19T22:56:05Z

Centralize reading of symlink destinations and the contents of regular files that are too small to be streamed. This reduces code duplication and allows future patches to add support for adding non-tracked files to archives. The backends are expected to stream blobs if buffer is NULL. object_file_to_archive() is only called from archive.c and thus no longer exported.

wt-status: tolerate dangling marks

2020-09-02T21:39:25Z

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().

convert: provide additional metadata to filters

2020-03-16T18:37:02Z

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. Signed-off-by: brian m. carlson Signed-off-by: Junio C Hamano

convert: permit passing additional metadata to filter processes

2020-03-16T18:37:02Z

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 Signed-off-by: Junio C Hamano

Merge branch 'en/merge-directory-renames'

2019-05-08T15:37:22Z

"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

Use 'unsigned short' for mode, like diff_filespec does

2019-04-08T07:02:07Z

struct diff_filespec defines mode to be an 'unsigned short'. Several other places in the API which we'd like to interact with using a diff_filespec used a plain unsigned (or unsigned int). This caused problems when taking addresses, so switch to unsigned short. Signed-off-by: Elijah Newren Signed-off-by: Junio C Hamano

archive: convert struct archiver_args to object_id

2019-04-01T02:57:39Z

Change the commit_sha1 member to be called "commit_oid" and change it to be a pointer to struct object_id. Additionally, update some uses of GIT_SHA1_HEXSZ and hard-coded values to use the_hash_algo instead. Signed-off-by: brian m. carlson Signed-off-by: Junio C Hamano
