| 1 | DebWrt patch subsystem to patch OpenWrt |
|---|
| 2 | |
|---|
| 3 | Reworked by ehem since r349. Thanks! |
|---|
| 4 | |
|---|
| 5 | all/ Patches that apply to all branches of OpenWrt |
|---|
| 6 | trunk/ Patches that apply only to OpenWrt trunk |
|---|
| 7 | backfire/ Patches that apply only to OpenWrt backfire branch |
|---|
| 8 | |
|---|
| 9 | Patches in these directories must have filenames of the form: |
|---|
| 10 | |
|---|
| 11 | <nnn>_<desc> |
|---|
| 12 | Apply patch to all revisions |
|---|
| 13 | <nnn>[-<branch>][-[<first>]:[<last>]]_<desc> |
|---|
| 14 | The portions in brackets [] are optional. If present, <branch> will |
|---|
| 15 | cause the patch to only be applied to the indicated branch of OpenWrt, |
|---|
| 16 | "all" will make it applIy to all branches. <first> and <last> are used |
|---|
| 17 | to indicate an inclusive range of OpenWrt revisions which the patch |
|---|
| 18 | applies to. If <last> is omitted, it will be applied to all revisions |
|---|
| 19 | after <first>. If <first> is omitted, it will be applied to all |
|---|
| 20 | revisions before <last>. If <first> equals <last>, it will be applied |
|---|
| 21 | to that single revision. If <first> is greater than <last>, it will |
|---|
| 22 | never be used. |
|---|
| 23 | |
|---|
| 24 | |
|---|
| 25 | <nnn> is used to set order of application. Lower numbered patches are applied |
|---|
| 26 | first. The ordering is done by running the list of patches through |
|---|
| 27 | `sort`, as a result, "1000_foo" will be done before "200_bar". |
|---|
| 28 | |
|---|
| 29 | <desc> contains a functional description of the patch. Usually separated by |
|---|
| 30 | underscores. |
|---|
| 31 | |
|---|
| 32 | Minor technical note: The script is actually trying to parse everything up to |
|---|
| 33 | the first underscore. Everything after that is ignored. |
|---|
| 34 | |
|---|
| 35 | |
|---|
| 36 | Patches are applied inside the checked out OpenWRT using `patch -p0`. Patches |
|---|
| 37 | directly from other sources may need to be adjusted to match this (the command |
|---|
| 38 | `sed -e's/^\(\(+++\)\|\(---\)\) [^\/]*\//\1 /' -i` will do this). |
