Currently, merging across changes in line ending normalization is
painful since files containing CRLF will conflict with normalized files,
even if the only difference between the two versions is the line
endings. Additionally, any "real" merge conflicts that exist are
obscured because every line in the file has a conflict.
Assume you start out with a repo that has a lot of text files with CRLF
checked in (A):
o---C
/ \
A---B---D
B: Add "* text=auto" to .gitattributes and normalize all files to
LF-only
C: Modify some of the text files
D: Try to merge C
You will get a ridiculous number of LF/CRLF conflicts when trying to
merge C into D, since the repository contents for C are "wrong" wrt the
new .gitattributes file.
Fix ll-merge so that the "base", "theirs" and "ours" stages are passed
through convert_to_worktree() and convert_to_git() before a three-way
merge. This ensures that all three stages are normalized in the same
way, removing from consideration differences that are only due to
normalization.
This feature is optional for now since it changes a low-level mechanism
and is not necessary for the majority of users. The "merge.renormalize"
config variable enables it.

merge.conflictstyle::
|
|
Specify the style in which conflicted hunks are written out to
|
|
working tree files upon merge. The default is "merge", which
|
|
shows a `<<<<<<<` conflict marker, changes made by one side,
|
|
a `=======` marker, changes made by the other side, and then
|
|
a `>>>>>>>` marker. An alternate style, "diff3", adds a `|||||||`
|
|
marker and the original text before the `=======` marker.
|
|
|
|
merge.log::
|
|
Whether to include summaries of merged commits in newly created
|
|
merge commit messages. False by default.
|
|
|
|
merge.renameLimit::
|
|
The number of files to consider when performing rename detection
|
|
during a merge; if not specified, defaults to the value of
|
|
diff.renameLimit.
|
|
|
|
merge.renormalize::
|
|
Tell git that canonical representation of files in the
|
|
repository has changed over time (e.g. earlier commits record
|
|
text files with CRLF line endings, but recent ones use LF line
|
|
endings). In such a repository, git can convert the data
|
|
recorded in commits to a canonical form before performing a
|
|
merge to reduce unnecessary conflicts. For more information,
|
|
see section "Merging branches with differing checkin/checkout
|
|
attributes" in linkgit:gitattributes[5].
|
|
|
|
merge.stat::
|
|
Whether to print the diffstat between ORIG_HEAD and the merge result
|
|
at the end of the merge. True by default.
|
|
|
|
merge.tool::
|
|
Controls which merge resolution program is used by
|
|
linkgit:git-mergetool[1]. Valid built-in values are: "kdiff3",
|
|
"tkdiff", "meld", "xxdiff", "emerge", "vimdiff", "gvimdiff",
|
|
"diffuse", "ecmerge", "tortoisemerge", "p4merge", "araxis" and
|
|
"opendiff". Any other value is treated is custom merge tool
|
|
and there must be a corresponding mergetool.<tool>.cmd option.
|
|
|
|
merge.verbosity::
|
|
Controls the amount of output shown by the recursive merge
|
|
strategy. Level 0 outputs nothing except a final error
|
|
message if conflicts were detected. Level 1 outputs only
|
|
conflicts, 2 outputs conflicts and file changes. Level 5 and
|
|
above outputs debugging information. The default is level 2.
|
|
Can be overridden by the 'GIT_MERGE_VERBOSITY' environment variable.
|
|
|
|
merge.<driver>.name::
|
|
Defines a human-readable name for a custom low-level
|
|
merge driver. See linkgit:gitattributes[5] for details.
|
|
|
|
merge.<driver>.driver::
|
|
Defines the command that implements a custom low-level
|
|
merge driver. See linkgit:gitattributes[5] for details.
|
|
|
|
merge.<driver>.recursive::
|
|
Names a low-level merge driver to be used when
|
|
performing an internal merge between common ancestors.
|
|
See linkgit:gitattributes[5] for details.
