7 git-merge-cache - Runs a merge for files needing merging
12 'git-merge-cache' [-o] [-q] <merge-program> (-a | -- | <file>\*)
16 This looks up the <file>(s) in the cache and, if there are any merge
17 entries, passes the SHA1 hash for those files as arguments 1, 2, 3 (empty
18 argument if no file), and <file> as argument 4. File modes for the three
19 files are passed as arguments 5, 6 and 7.
24 Interpret all following arguments as filenames.
27 Run merge against all files in the cache that need merging.
30 Instead of stopping at the first failed merge, do all of them
31 in one shot - continue with merging even when previous merges
32 returned errors, and only return the error code after all the
36 Do not complain about failed merge program (the merge program
37 failure usually indicates conflicts during merge). This is for
38 porcelains which might want to emit custom messages.
40 If "git-merge-cache" is called with multiple <file>s (or -a) then it
41 processes them in turn only stopping if merge returns a non-zero exit
44 Typically this is run with the a script calling the merge command from
47 A sample script called "git-merge-one-file-script" is included in the
50 ALERT ALERT ALERT! The git "merge object order" is different from the
51 RCS "merge" program merge object order. In the above ordering, the
52 original is first. But the argument order to the 3-way merge program
53 "merge" is to have the original in the middle. Don't ask me why.
57 torvalds@ppc970:~/merge-test> git-merge-cache cat MM
58 This is MM from the original tree. # original
59 This is modified MM in the branch A. # merge1
60 This is modified MM in the branch B. # merge2
61 This is modified MM in the branch B. # current contents
65 torvalds@ppc970:~/merge-test> git-merge-cache cat AA MM
66 cat: : No such file or directory
67 This is added AA in the branch A.
68 This is added AA in the branch B.
69 This is added AA in the branch B.
70 fatal: merge program failed
72 where the latter example shows how "git-merge-cache" will stop trying to
73 merge once anything has returned an error (ie "cat" returned an error
74 for the AA file, because it didn't exist in the original, and thus
75 "git-merge-cache" didn't even try to merge the MM thing).
