histories diverged from the current branch) into the current

from another repository and can be used by hand to merge changes

from one branch into another.</p>

<p>The second syntax ("<code>git merge --abort</code>") can only be run after the

|
merge has resulted in conflicts. <em>git merge --abort</em> will abort the
|
|
merge process and try to reconstruct the pre-merge state. However,
|
|
if there were uncommitted changes when the merge started (and
|
|
especially if those changes were further modified after the merge
|
|
was started), <em>git merge --abort</em> will in some cases be unable to
|
|
reconstruct the original (pre-merge) changes. Therefore:</p>

<p>The merge mechanism (<code>git merge</code> and <code>git pull</code> commands) allows the
|
|
backend <em>merge strategies</em> to be chosen with <code>-s</code> option. Some strategies
|
|
can also take their own options, which can be passed by giving <code>-X<option></code>
|
|
arguments to <code>git merge</code> and/or <code>git pull</code>.</p>

<p>This can only resolve two heads (i.e. the current branch
|

and another branch you pulled from) using a 3-way merge

fast.</p>

<dt class="hdlist1">recursive</dt>

<dd>
|
|
<p>This can only resolve two heads using a 3-way merge
|
|
algorithm. When there is more than one common
|
|
ancestor that can be used for 3-way merge, it creates a
|
|
merged tree of the common ancestors and uses that as
|
|
the reference tree for the 3-way merge. This has been
|
|
reported to result in fewer merge conflicts without
|
|
causing mismerges by tests done on actual merge commits
|
|
taken from Linux 2.6 kernel development history.
|
|
Additionally this can detect and handle merges involving
|
|
renames, but currently cannot make use of detected
|
|
copies. This is the default merge strategy when pulling
|
|
or merging one branch.</p>

<p>This option forces conflicting hunks to be auto-resolved cleanly by

favoring <em>our</em> version. Changes from the other tree that do not

conflict with our side are reflected to the merge result.
|

For a binary file, the entire contents are taken from our side.</p>

<div class="paragraph">

<p>This should not be confused with the <em>ours</em> merge strategy, which does not

the strategy makes a guess on how two trees must be shifted to

<p>This resolves any number of heads, but the resulting tree of the

ignoring all changes from all other branches. It is meant to

<p>This is a modified recursive strategy. When merging trees A and

<p>With the strategies that use 3-way merge (including the default, <em>recursive</em>),

if a change is made on both branches, but later reverted on one of the

|
|
this behavior confusing. It occurs because only the heads and the merge base
|
|
are considered when performing a merge, not the individual commits. The merge

algorithm therefore considers the reverted change as no change at all, and

substitutes the changed version instead.</p>
