NAME
|
|
----
|
|
git-replace - Create, list, delete refs to replace objects
|
|
|
|
SYNOPSIS
|
|
--------
|
|
[verse]
|
|
'git replace' [-f] <object> <replacement>
|
|
'git replace' [-f] --edit <object>
|
|
'git replace' [-f] --graft <commit> [<parent>...]
|
|
'git replace' -d <object>...
|
|
'git replace' [--format=<format>] [-l [<pattern>]]
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
Adds a 'replace' reference in `refs/replace/` namespace.
|
|
|
|
The name of the 'replace' reference is the SHA-1 of the object that is
|
|
replaced. The content of the 'replace' reference is the SHA-1 of the
|
|
replacement object.
|
|
|
|
The replaced object and the replacement object must be of the same type.
|
|
This restriction can be bypassed using `-f`.
|
|
|
|
Unless `-f` is given, the 'replace' reference must not yet exist.
|
|
|
|
There is no other restriction on the replaced and replacement objects.
|
|
Merge commits can be replaced by non-merge commits and vice versa.
|
|
|
|
Replacement references will be used by default by all Git commands
|
|
except those doing reachability traversal (prune, pack transfer and
|
|
fsck).
|
|
|
|
It is possible to disable use of replacement references for any
|
|
command using the `--no-replace-objects` option just after 'git'.
|
|
|
|
For example if commit 'foo' has been replaced by commit 'bar':
|
|
|
|
------------------------------------------------
|
|
$ git --no-replace-objects cat-file commit foo
|
|
------------------------------------------------
|
|
|
|
shows information about commit 'foo', while:
|
|
|
|
------------------------------------------------
|
|
$ git cat-file commit foo
|
|
------------------------------------------------
|
|
|
|
shows information about commit 'bar'.
|
|
|
|
The 'GIT_NO_REPLACE_OBJECTS' environment variable can be set to
|
|
achieve the same effect as the `--no-replace-objects` option.
|
|
|
|
OPTIONS
|
|
-------
|
|
-f::
|
|
--force::
|
|
If an existing replace ref for the same object exists, it will
|
|
be overwritten (instead of failing).
|
|
|
|
-d::
|
|
--delete::
|
|
Delete existing replace refs for the given objects.
|
|
|
|
--edit <object>::
|
|
Edit an object's content interactively. The existing content
|
|
for <object> is pretty-printed into a temporary file, an
|
|
editor is launched on the file, and the result is parsed to
|
|
create a new object of the same type as <object>. A
|
|
replacement ref is then created to replace <object> with the
|
|
newly created object. See linkgit:git-var[1] for details about
|
|
how the editor will be chosen.
|
|
|
|
--raw::
|
|
When editing, provide the raw object contents rather than
|
|
pretty-printed ones. Currently this only affects trees, which
|
|
will be shown in their binary form. This is harder to work with,
|
|
but can help when repairing a tree that is so corrupted it
|
|
cannot be pretty-printed. Note that you may need to configure
|
|
your editor to cleanly read and write binary data.
|
|
|
|
--graft <commit> [<parent>...]::
|
|
Create a graft commit. A new commit is created with the same
|
|
content as <commit> except that its parents will be
|
|
[<parent>...] instead of <commit>'s parents. A replacement ref
|
|
is then created to replace <commit> with the newly created
|
|
commit. See contrib/convert-grafts-to-replace-refs.sh for an
|
|
example script based on this option that can convert grafts to
|
|
replace refs.
|
|
|
|
-l <pattern>::
|
|
--list <pattern>::
|
|
List replace refs for objects that match the given pattern (or
|
|
all if no pattern is given).
|
|
Typing "git replace" without arguments, also lists all replace
|
|
refs.
|
|
|
|
--format=<format>::
|
|
When listing, use the specified <format>, which can be one of
|
|
'short', 'medium' and 'long'. When omitted, the format
|
|
defaults to 'short'.
|
|
|
|
FORMATS
|
|
-------
|
|
|
|
The following format are available:
|
|
|
|
* 'short':
|
|
<replaced sha1>
|
|
* 'medium':
|
|
<replaced sha1> -> <replacement sha1>
|
|
* 'long':
|
|
<replaced sha1> (<replaced type>) -> <replacement sha1> (<replacement type>)
|
|
|
|
CREATING REPLACEMENT OBJECTS
|
|
----------------------------
|
|
|
|
linkgit:git-filter-branch[1], linkgit:git-hash-object[1] and
|
|
linkgit:git-rebase[1], among other git commands, can be used to create
|
|
replacement objects from existing objects. The `--edit` option can
|
|
also be used with 'git replace' to create a replacement object by
|
|
editing an existing object.
|
|
|
|
If you want to replace many blobs, trees or commits that are part of a
|
|
string of commits, you may just want to create a replacement string of
|
|
commits and then only replace the commit at the tip of the target
|
|
string of commits with the commit at the tip of the replacement string
|
|
of commits.
|
|
|
|
BUGS
|
|
----
|
|
Comparing blobs or trees that have been replaced with those that
|
|
replace them will not work properly. And using `git reset --hard` to
|
|
go back to a replaced commit will move the branch to the replacement
|
|
commit instead of the replaced commit.
|
|
|
|
There may be other problems when using 'git rev-list' related to
|
|
pending objects.
