merge API
|
|
=========
|
|
|
|
The merge API helps a program to reconcile two competing sets of
|
|
improvements to some files (e.g., unregistered changes from the work
|
|
tree versus changes involved in switching to a new branch), reporting
|
|
conflicts if found. The library called through this API is
|
|
responsible for a few things.
|
|
|
|
* determining which trees to merge (recursive ancestor consolidation);
|
|
|
|
* lining up corresponding files in the trees to be merged (rename
|
|
detection, subtree shifting), reporting edge cases like add/add
|
|
and rename/rename conflicts to the user;
|
|
|
|
* performing a three-way merge of corresponding files, taking
|
|
path-specific merge drivers (specified in `.gitattributes`)
|
|
into account.
|
|
|
|
Data structures
|
|
---------------
|
|
|
|
* `mmbuffer_t`, `mmfile_t`
|
|
|
|
These store data usable for use by the xdiff backend, for writing and
|
|
for reading, respectively. See `xdiff/xdiff.h` for the definitions
|
|
and `diff.c` for examples.
|
|
|
|
* `struct ll_merge_options`
|
|
|
|
Check ll-merge.h for details.
|
|
|
|
Low-level (single file) merge
|
|
-----------------------------
|
|
|
|
Check ll-merge.h for details.
