This also bumps the stable nixpkgs to 20.09 as of 2020-11-21, because there is some breakage in the git build related to the netrc credentials helper which someone has taken care of in nixpkgs. The stable channel is not used for anything other than git, so this should be fine. Change-Id: I3575a19dab09e1e9556cf8231d717de9890484fb

git-merge-index(1)

|
==================
|
|
|
|
NAME
|
|
----
|
|
git-merge-index - Run a merge for files needing merging
|
|
|
|
|
|
SYNOPSIS
|
|
--------
|
|
[verse]
|
|
'git merge-index' [-o] [-q] <merge-program> (-a | [--] <file>*)
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
This looks up the <file>(s) in the index and, if there are any merge
|
|
entries, passes the SHA-1 hash for those files as arguments 1, 2, 3 (empty
|
|
argument if no file), and <file> as argument 4. File modes for the three
|
|
files are passed as arguments 5, 6 and 7.
|
|
|
|
OPTIONS
|
|
-------
|
|
\--::
|
|
Do not interpret any more arguments as options.
|
|
|
|
-a::
|
|
Run merge against all files in the index that need merging.
|
|
|
|
-o::
|
|
Instead of stopping at the first failed merge, do all of them
|
|
in one shot - continue with merging even when previous merges
|
|
returned errors, and only return the error code after all the
|
|
merges.
|
|
|
|
-q::
|
|
Do not complain about a failed merge program (a merge program
|
|
failure usually indicates conflicts during the merge). This is for
|
|
porcelains which might want to emit custom messages.
|
|
|
|
If 'git merge-index' is called with multiple <file>s (or -a) then it
|
|
processes them in turn only stopping if merge returns a non-zero exit
|
|
code.
|
|
|
|
Typically this is run with a script calling Git's imitation of
|
|
the 'merge' command from the RCS package.
|
|
|
|
A sample script called 'git merge-one-file' is included in the
|
|
distribution.
|
|
|
|
ALERT ALERT ALERT! The Git "merge object order" is different from the
|
|
RCS 'merge' program merge object order. In the above ordering, the
|
|
original is first. But the argument order to the 3-way merge program
|
|
'merge' is to have the original in the middle. Don't ask me why.
|
|
|
|
Examples:
|
|
|
|
----
|
|
torvalds@ppc970:~/merge-test> git merge-index cat MM
|
|
This is MM from the original tree. # original
|
|
This is modified MM in the branch A. # merge1
|
|
This is modified MM in the branch B. # merge2
|
|
This is modified MM in the branch B. # current contents
|
|
----
|
|
|
|
or
|
|
|
|
----
|
|
torvalds@ppc970:~/merge-test> git merge-index cat AA MM
|
|
cat: : No such file or directory
|
|
This is added AA in the branch A.
|
|
This is added AA in the branch B.
|
|
This is added AA in the branch B.
|
|
fatal: merge program failed
|
|
----
|
|
|
|
where the latter example shows how 'git merge-index' will stop trying to
|
|
merge once anything has returned an error (i.e., `cat` returned an error
|
|
for the AA file, because it didn't exist in the original, and thus
|
|
'git merge-index' didn't even try to merge the MM thing).
