2007-12-11Support a merge with conflicting gitlink changeJunio C Hamano
merge-recursive did not support merging trees that have conflicting changes in submodules they contain, and died. Support it exactly the same way as how it handles conflicting symbolic link changes --- mark it as a conflict, take the tentative result from the current side, and letting the caller resolve the conflict, without dying in merge_file() function. Also reword the error message issued when merge_file() has to die because it sees a tree entry of type it does not support yet.

2007-10-29merge-recursive.c: mrtree in merge() is not used before setJunio C Hamano
The called function merge_trees() sets its *result, to which the address of the variable mrtree in merge() function is passed, only when index_only is set. But that is Ok as the function uses the value in the variable only under index_only iteration. However, recent gcc does not realize this. Work it around by adding a fake initializer.

2007-09-26Make merge-recursive honor diff.renamelimitLars Hjemli
It might be a sign of source code management gone bad, but when two branches has diverged almost beyond recognition and time has come for the branches to merge, the user is going to need all the help his tool can give him. Honoring diff.renamelimit has great potential as a painkiller in such situations. The painkiller effect could have been achieved by e.g. 'merge.renamelimit', but the flexibility gained by a separate option is questionable: our user would probably expect git to detect renames equally good when merging as when diffing (I known I did).

2007-08-15merge-recursive: do not rudely die on binary mergeJunio C Hamano
When you try to merge a path that involves binary file-level merge, merge-recursive died rudely without cleaning up its own mess. A files added by the merge were left in the working tree, but the index was not written out (because it just punted and died), so it was cumbersome for the user to retry it by first running "git reset --hard". This changes merge-recursive to still warn but do the "binary" merge for such a path; leave the "our" version in the working tree, but still keep the path unmerged so that the user can sort it out.

2007-08-10Start moving unpack-trees to "struct tree_desc"Linus Torvalds
This doesn't actually change any real code, but it changes the interface to unpack_trees() to take an array of "struct tree_desc" entries, the same way the tree-walk.c functions do. The reason for this is that we would be much better off if we can do the tree-unpacking using the generic "traverse_trees()" functionality instead of having to the special "unpack" infrastructure. This really is a pretty minimal diff, just to change the calling convention. It passes all the tests, and looks sane. There were only two users of "unpack_trees()": builtin-read-tree and merge-recursive, and I tried to keep the changes minimal.

2007-04-20Kill the useless progress meter in merge-recursiveShawn O. Pearce
The mess known as the progress meter in merge-recursive was my own fault; I put it in thinking that we might be spending a lot of time resolving unmerged entries in the index that were not handled by the simple 3-way index merge code. Turns out we don't really spend that much time there, so the progress meter was pretty much always jumping to "(n/n) 100%" as soon as the program started. That isn't a very good indication of progress. Since I don't have a great solution for how a progress meter should work here, I'm proposing we back it out entirely. Signed-off-by: Shawn O.

2007-04-20Fix working directory errno handling when unlinking a directoryLinus Torvalds
Alex Riesen noticed that the case where a file replaced a directory entry in the working tree was broken on cygwin. It turns out that the code made some Linux-specific assumptions, and also ignored errors entirely for the case where the entry was a symlink rather than a file. This cleans it up by separating out the common case into a function of its own, so that both regular files and symlinks can share it, and by making the error handling more obvious (and not depend on any Linux-specific behaviour).

2007-04-18Fix funny types used in attribute value representationJunio C Hamano
It was bothering me a lot that I abused small integer values casted to (void *) to represent non string values in gitattributes. This corrects it by making the type of attribute values (const char *), and using the address of a few statically allocated character buffer to denote true/false. Unset attributes are represented as having NULLs as their values. Added in-header documentation to explain how git_checkattr() routine should be called. Signed-off-by: Junio C Hamano <junkio@cox.net>
2007-04-18Allow low-level driver to specify different behaviour during internal merge.Junio C Hamano

2007-04-18Custom low-level merge driver: change the configuration scheme.Junio C Hamano
This changes the configuration syntax for defining a low-level merge driver to be: [merge "<<drivername>>"] driver = "<<command line>>" name = "<<driver description>>" which is much nicer to read and is extensible. Credit goes to Martin Waitz and Linus. In addition, when we use an external low-level merge driver, it is reported as an extra output from merge-recursive, using the value of merge.<<drivername>.name variable. The demonstration in t6026 has also been updated. Signed-off-by: Junio C Hamano <junkio@cox.net>
2007-04-18Allow the default low-level merge driver to be configured.Junio C Hamano

2007-04-18Custom low-level merge driver support.Junio C Hamano
This allows users to specify custom low-level merge driver per path, using the attributes mechanism. Just like you can specify one of built-in "text", "binary", "union" low-level merge drivers by saying: * merge=text .gitignore merge=union *.jpg merge=binary pick a name of your favorite merge driver, and assign it as the value of the 'merge' attribute. A custom low-level merge driver is defined via the config mechanism. This patch introduces 'merge.driver', a multi-valued configuration. Its value is the name (i.e. the one you use as the value of 'merge' attribute) followed by a command line specification. The command line can contain %O, %A, and %B to be interpolated with the names of temporary files that hold the common ancestor version, the version from your branch, and the version from the other branch, and the resulting command is spawned. The low-level merge driver is expected to update the temporary file for your branch (i.e. %A) with the result and exit with status 0 for a clean merge, and non-zero status for a conflicted merge. A new test in t6026 demonstrates a sample usage. Signed-off-by: Junio C Hamano <junkio@cox.net>
2007-04-17Allow specifying specialized merge-backend per path.Junio C Hamano
This allows 'merge' attribute to control how the file-level three-way merge is done per path. - If you set 'merge' to true, leave it unspecified, or set it to "text", we use the built-in 3-way xdl-merge. - If you set 'merge' to false, or set it to "binary, the "binary" merge is done. The merge result is the blob from 'our' tree, but this still leaves the path conflicted, so that the mess can be sorted out by the user. This is obviously meant to be useful for binary files. - 'merge=union' (this is the first example of a string valued attribute, introduced in the previous one) uses the "union" merge. The "union" merge takes lines in conflicted hunks from both sides, which is useful for line-oriented files such as .gitignore. Instead fo setting merge to 'true' or 'false' by using 'merge' or '-merge', setting it explicitly to "text" or "binary" will become useful once we start allowing custom per-path backends to be added, and allow them to be activated for the default (i.e. 'merge' attribute specified to 'true' or 'false') case, using some other mechanisms. Setting merge attribute to "text" or "binary" will be a way to explicitly request to override such a custom default for selected paths. Currently there is no way to specify random programs but it should be trivial for motivated contributors to add later. There is one caveat, though. ll_merge() is called for both internal ancestor merge and the outer "final" merge. I think an interactive custom per-path merge backend should refrain from going interactive when performing an internal merge (you can tell it by checking call_depth) and instead just call either ll_xdl_merge() if the content is text, or call ll_binary_merge() otherwise.

2007-04-10merge-recursive: handle D/F conflict case more carefully.Junio C Hamano
When a path D that originally was blob in the ancestor was modified on our branch while it was removed on the other branch, we keep stages 1 and 2, and leave our version in the working tree. If the other branch created a path D/F, however, that path can cleanly be resolved in the index (after all, the ancestor nor we do not have it and only the other side added), but it cannot be checked out. The issue is the same when the other branch had D and we had renamed it to D/F, or the ancestor had D/F instead of D (so there are four combinations). Do not stop the merge, but leave both D and D/F paths in the index so that the user can clear things up. Signed-off-by: Junio C Hamano <junkio@cox.net>
2007-04-10merge-recursive: do not barf on "to be removed" entries.Junio C Hamano
When update-trees::threeway_merge() decides that a path that exists in the current index (and HEAD) is to be removed, it leaves a stage 0 entry whose mode bits are set to 0. The code mistook it as "this stage wants the blob here", and proceeded to call update_file_flags() which ended up trying to put the mode=0 entry in the index, got very confused, and ended up barfing with "do not know what to do with 000000". Since threeway_merge() does not handle case #10 (one side removes while the other side does not do anything), this is not a problem while we refuse to merge branches that have D/F conflicts, but when we start resolving them, we would need to be able to remove cache entries, and at that point it starts to matter. Signed-off-by: Junio C Hamano <junkio@cox.net>
2007-04-07A new merge stragety 'subtree'.Junio C Hamano
This merge strategy largely piggy-backs on git-merge-recursive. When merging trees A and B, if B corresponds to a subtree of A, B is first adjusted to match the tree structure of A, instead of reading the trees at the same level. This adjustment is also done to the common ancestor tree. If you are pulling updates from git-gui repository into git.git repository, the root level of the former corresponds to git-gui/ subdirectory of the latter. The tree object of git-gui's toplevel is wrapped in a fake tree object, whose sole entry has name 'git-gui' and records object name of the true tree, before being used by the 3-way merge code. If you are merging the other way, only the git-gui/ subtree of git.git is extracted and merged into git-gui's toplevel. The detection of corresponding subtree is done by comparing the pathnames and types in the toplevel of the tree. Heuristics galore! That's the git way ;-).

This error message should not usually trigger, but the function make_cache_entry() called by add_cacheinfo() can return early without calling into refresh_cache_entry() that sets cache_errno.

2007-04-04_GIT_INDEX_OUTPUT: allow plumbing to output to an alternative index file.Junio C Hamano
When defined, this allows plumbing commands that update the index (add, apply, checkout-index, merge-recursive, mv, read-tree, rm, update-index, and write-tree) to write their resulting index to an alternative index file while holding a lock to the original index file. With this, git-commit that jumps the index does not have to make an extra copy of the index file, and more importantly, it can do the update while holding the lock on the index. However, I think the interface to let an environment variable specify the output is a mistake, as shown in the documentation. If a curious user has the environment variable set to something other than the file GIT_INDEX_FILE points at, almost everything will break. This should instead be a command line parameter to tell these plumbing commands to write the result in the named file, to prevent stupid mistakes. Signed-off-by: Junio C Hamano <junkio@cox.net>

The null tree does not have to be written out in the object store as it won't be part of the result, and it is a prime example for using the new pretend_sha1_file() function. git-blame needs to register an arbitrary data to in-core index while annotating a working tree file (or standard input), but git-blame is a read-only application and the user of it could even lack the privilege to write into the object store; it is another good example for pretend_sha1_file().

2007-02-04Keep untracked files not involved in a merge.Shawn O. Pearce
My earlier fix (8371234e) to delete renamed tracked files from the working directory also caused merge-recursive to delete untracked files that were in the working directory. The problem here is merge-recursive is deleting the working directory file without regard for which branch it was associated with. What we really want to do during a merge is to only delete files that were renamed by the branch we are merging into the current branch, and that are still tracked by the current branch. These files definitely don't belong in the working directory anymore. Anything else is either a merge conflict (already handled in other parts of the code) or a file that is untracked by the current branch and thus is not even participating in the merge. Its this latter class that must be left alone. For this fix to work we are now assuming that the first non-base argument passed to git-merge-recursive always corresponds to the working directory. This is already true for all in-tree callers of merge-recursive. This assumption is also supported by the long time usage message of "<base> ... -- <head> <remote>", where "<head>" is implied to be HEAD, which is generally assumed to be the current tree-ish.

Because large merges on slow systems can take up to a minute to execute we should try to keep the user entertained with a progress meter to let them know how far we have progressed through the current merge. The progress meter considers each entry in the in-memory index to be a unit, which means a single recursive merge will double the number of units in the progress meter. Files which are unmerged after the 3-way tree merge are also considered a unit within the progress meter. Signed-off-by: Shawn O.

2007-01-14Enable output buffering in merge-recursive.Shawn O. Pearce
Buffering all message output until a merge invocation is complete is necessary to prevent intereferring with a progress meter that would indicate the number of files completely merged, and how many remain. This change does not introduce a progress meter, but merely lays the groundwork to buffer the output. To aid debugging output buffering is only enabled if verbosity is lower than 5. When using verbosity levels above 5 the user is probably debugging the merge program itself and does not want to see the output delayed, especially if they are stepping through portions of the code in a debugger.
