Git Apply Patch Wow

Git: How to create and apply patches. You can use git apply some.patch to have the changes from the. patch file applied to your current working directory.

Some older patches may require patch -p0 or git apply -p0 to apply correctly, but patches made with git should all be -p1 compatible.

• -R --reverse Apply the patch in reverse. --reject For atomicity, git apply by default fails the whole patch and does not touch the working tree when some of.

The files to read the patch from. - can be used to read

from the standard input.

--stat

Instead of applying the patch, output diffstat for the

input. Turns off apply.

--numstat

Similar to --stat, but shows the number of added and

deleted lines in decimal notation and the pathname without

abbreviation, to make it more machine friendly. For

binary files, outputs two - instead of saying

0 0. Turns off apply.

--summary

Instead of applying the patch, output a condensed

summary of information obtained from git diff extended

headers, such as creations, renames and mode changes.

Turns off apply.

--check

Instead of applying the patch, see if the patch is

applicable to the current working tree and/or the index

file and detects errors. Turns off apply.

--index

When --check is in effect, or when applying the patch

which is the default when none of the options that

disables it is in effect, make sure the patch is

applicable to what the current index file records. If

the file to be patched in the working tree is not

up-to-date, it is flagged as an error. This flag also

causes the index file to be updated.

--cached

Apply a patch without touching the working tree. Instead take the

cached data, apply the patch, and store the result in the index

without using the working tree. This implies --index.

-3

--3way

When the patch does not apply cleanly, fall back on 3-way merge if

the patch records the identity of blobs it is supposed to apply to,

and we have those blobs available locally, possibly leaving the

conflict markers in the files in the working tree for the user to

resolve. This option implies the --index option, and is incompatible

with the --reject and the --cached options.

--build-fake-ancestor

Newer git diff output has embedded index information

for each blob to help identify the original version that

the patch applies to. When this flag is given, and if

the original versions of the blobs are available locally,

builds a temporary index containing those blobs.

When a pure mode change is encountered which has no index information,

the information is read from the current index instead.

-R

--reverse

Apply the patch in reverse.

--reject

For atomicity, git apply by default fails the whole patch and

does not touch the working tree when some of the hunks

do not apply. This option makes it apply

the parts of the patch that are applicable, and leave the

rejected hunks in corresponding . rej files.

-z

When --numstat has been given, do not munge pathnames,

but use a NUL-terminated machine-readable format.

Without this option, each pathname output will have TAB, LF, double quotes,

and backslash characters replaced with t, n, , and ,

respectively, and the pathname will be enclosed in double quotes if

any of those replacements occurred.

-p

Remove leading slashes from traditional diff paths. The

default is 1.

-C

Ensure at least lines of surrounding context match before

and after each change. When fewer lines of surrounding

context exist they all must match. By default no context is

ever ignored.

--unidiff-zero

By default, git apply expects that the patch being

applied is a unified diff with at least one line of context.

This provides good safety measures, but breaks down when

applying a diff generated with --unified 0. To bypass these

checks use --unidiff-zero.

Note, for the reasons stated above usage of context-free patches is

discouraged.

--apply

If you use any of the options marked Turns off

apply above, git apply reads and outputs the

requested information without actually applying the

patch. Give this flag after those flags to also apply

the patch.

--no-add

When applying a patch, ignore additions made by the

patch. This can be used to extract the common part between

two files by first running diff on them and applying

the result with this option, which would apply the

deletion part but not the addition part.

--allow-binary-replacement

--binary

Historically we did not allow binary patch applied

without an explicit permission from the user, and this

flag was the way to do so. Currently we always allow binary

patch application, so this is a no-op.

--exclude

Don t apply changes to files matching the given path pattern. This can

be useful when importing patchsets, where you want to exclude certain

files or directories.

--include

Apply changes to files matching the given path pattern. This can

be useful when importing patchsets, where you want to include certain

When --exclude and --include patterns are used, they are examined in the

order they appear on the command line, and the first match determines if a

patch to each path is used. A patch to a path that does not match any

include/exclude pattern is used by default if there is no include pattern

on the command line, and ignored if there is any include pattern.

--ignore-space-change

--ignore-whitespace

When applying a patch, ignore changes in whitespace in context

lines if necessary.

Context lines will preserve their whitespace, and they will not

undergo whitespace fixing regardless of the value of the

--whitespace option. New lines will still be fixed, though.

--whitespace

When applying a patch, detect a new or modified line that has

whitespace errors. What are considered whitespace errors is

controlled by core.whitespace configuration. By default,

trailing whitespaces including lines that solely consist of

whitespaces and a space character that is immediately followed

by a tab character inside the initial indent of the line are

considered whitespace errors.

By default, the command outputs warning messages but applies the patch.

When git-apply is used for statistics and not applying a

patch, it defaults to nowarn.

You can use different values to control this

behavior:

nowarn turns off the trailing whitespace warning.

warn outputs warnings for a few such errors, but applies the

patch as-is default.

fix outputs warnings for a few such errors, and applies the

patch after fixing them strip is a synonym --- the tool

used to consider only trailing whitespace characters as errors, and the

fix involved stripping them, but modern Gits do more.

error outputs warnings for a few such errors, and refuses

to apply the patch.

error-all is similar to error but shows all errors.

--inaccurate-eof

Under certain circumstances, some versions of diff do not correctly

detect a missing new-line at the end of the file. As a result, patches

created by such diff programs do not record incomplete lines

correctly. This option adds support for applying such patches by

working around this bug.

-v

--verbose

Report progress to stderr. By default, only a message about the

current patch being applied will be printed. This option will cause

additional information to be reported.

--recount

Do not trust the line counts in the hunk headers, but infer them

by inspecting the patch e.g. after editing the patch without

adjusting the hunk headers appropriately.

--directory

Prepend to all filenames. If a -p argument was also passed,

it is applied before prepending the new root.

For example, a patch that talks about updating a/git-gui.sh to b/git-gui.sh

can be applied to the file in the working tree modules/git-gui/git-gui.sh by

running git apply --directory modules/git-gui.

--unsafe-paths

By default, a patch that affects outside the working area

either a Git controlled working tree, or the current working

directory when git apply is used as a replacement of GNU

patch is rejected as a mistake or a mischief.

When git apply is used as a better GNU patch, the user can pass

the --unsafe-paths option to override this safety check. This option

has no effect when --index or --cached is in use.
