patch – simple patch creation and tracking system
patch/create name email files ... [ < description ]
patch/list [ name ... ]
patch/note name [ < note ]
These scripts are a simple patch submission and tracking system
used to propose additions or changes to Plan 9. There is no guarantee
that any patch will be accepted, nor that it will be accepted
verbatim. Each patch has a name (lowercase letters, numbers, dash,
dot, and underscore only) and is stored in
Patch/create creates a new patch consisting of the changes to
the listed text files from the distribution, reading a description
of the patch from standard input: please provide an explanation
of what the change is supposed to do, some context, and a rationale
for the change. Please do not submit binary files. Test data
or pointers to same to verify that the fix works are also welcome.
When sending a patch, follow these guidelines:
The email address, if not –, will be sent notification messages when the patch is applied, rejected, or commented on. If rejected, the e–mail will contain a note explaining why and probably listing suggested changes and encouraging you to resubmit.
Patch/list displays information about the named patches, or all currently pending patches if none are specified.
Patch/diff shows a patch as diffs between the original source files and the patched source files.
Patch/apply applies the patch to the current source tree. It is intended to be run by the Plan 9 developers with pie as their root file system. If the source has changed since the patch was created, apply will report the conflict and not change any files. Before changing any files, patch/apply makes backup copies of the current source tree's files. The backups are stored in the patch directory.
Patch/undo will copy the backups saved by patch/apply back into
the source tree. It will not restore a backup if the file being
replaced is not byte–identical to the one created by patch/apply.
Propose a change to pwd, which you have modified locally:
