Heba Waly	d3d7172e40	merge: move doc to ll-merge.h Move the related documentation from Documentation/technical/api-merge.txt to ll-merge.h as it's easier for the developers to find the usage information beside the code instead of looking for it in another doc file. Only the ll-merge related doc is removed from documentation/technical/api-merge.txt because this information will be redundant and it'll be hard to keep it up to date and synchronized with the documentation in ll-merge.h.

brian m. carlson	2c65d90f75	am: reload .gitattributes after patching it When applying multiple patches with git am, or when rebasing using the am backend, it's possible that one of our patches has updated a gitattributes file. Currently, we cache this information, so if a file in a subsequent patch has attributes applied, the file will be written out with the attributes in place as of the time we started the rebase or am operation, not with the attributes applied by the previous patch. This problem does not occur when using the -m or -i flags to rebase. To ensure we write the correct data into the working tree, expire the cache after each patch that touches a path ending in ".gitattributes". Since we load these attributes in multiple separate files, we must expire them accordingly. Verify that both the am and rebase code paths work correctly, including the conflict marker size with am -3.

Elijah Newren	b2a7942b8b	merge-recursive: increase marker length with depth of recursion Later patches in this series will modify file collision conflict handling (e.g. from rename/add and rename/rename(2to1) conflicts) so that multiply nested conflict markers can arise even before considering conflicts in the virtual merge base. Including the virtual merge base will provide a way to get triply (or higher) nested conflict markers. This new way to get nested conflict markers will force the need for a more general mechanism to extend the length of conflict markers in order to differentiate between different nestings. Along with this change to conflict marker length handling, we want to make sure that we don't regress handling for other types of conflicts with nested conflict markers. Add a more involved testcase using merge.conflictstyle=diff3, where not only does the virtual merge base contain conflicts, but its virtual merge base does as well (i.e. a case with triply nested conflict markers). While there are multiple reasonable ways to handle nested conflict markers in the virtual merge base for this type of situation, the easiest approach that dovetails well with the new needs for the file collision conflict handling is to require that the length of the conflict markers increase with each subsequent nesting. Subsequent patches which change the rename/add and rename/rename(2to1) conflict handling will modify the extra_marker_size flag appropriately for their new needs.

Elijah Newren	ef3ca95475	Add missing includes and forward declarations I looped over the toplevel header files, creating a temporary two-line C program for each consisting of #include "git-compat-util.h" #include $HEADER This patch is the result of manually fixing errors in compiling those tiny programs.

Justin Frankel	58a1ece478	merge-recursive --patience Teach the merge-recursive strategy a --patience option to use the "patience diff" algorithm, which tends to improve results when cherry-picking a patch that reorders functions at the same time as refactoring them. To support this, struct merge_options and ll_merge_options gain an xdl_opts member, so programs can use arbitrary xdiff flags (think "XDF_IGNORE_WHITESPACE") in a git-aware merge. git merge and git rebase can be passed the -Xpatience option to use this.

Jonathan Nieder	712516bcac	ll-merge: replace flag argument with options struct Keeping track of the flag bits is proving more trouble than it's worth. Instead, use a pointer to an options struct like most similar APIs do. Callers with no special requests can pass NULL to request the default options.

Jonathan Nieder	18b037a5b6	ll-merge: let caller decide whether to renormalize Add a “renormalize” bit to the ll-merge options word so callers can decide on a case-by-case basis whether the merge is likely to have overlapped with a change in smudge/clean rules. This reveals a few commands that have not been taking that situation into account, though it does not fix them. No functional change intended.

Jonathan Nieder	73cf7f713d	ll-merge: make flag easier to populate ll_merge() takes its options in a flag word, which has a few advantages: - options flags can be cheaply passed around in registers, while an option struct passed by pointer cannot; - callers can easily pass 0 without trouble for no options, while an option struct passed by value would not allow that. The downside is that code to populate and access the flag word can be somewhat opaque. Mitigate that with a few macros.

Jonathan Nieder	f01de62e45	ll_merge(): add ancestor label parameter for diff3-style output Commands using the ll_merge() function will present conflict hunks imitating ‘diff3 -m’ output if the merge.conflictstyle configuration option is set appropriately. Unlike ‘diff3 -m’, the output does not include a label for the merge base on the \|\|\|\|\|\|\| line of the output, and some tools misparse the conflict hunks without that. Add a new ancestor_label parameter to ll_merge() to give callers the power to rectify this situation. If ancestor_label is NULL, the output format is unchanged. All callers pass NULL for now.
