external patch command not provided by bzr windows installer: makes "bzr patch" fails on win32

[Olivier Bilodeau]

`bzr patch` doesn't work on Windows. I know bzr patch is a part of bzrtools but I think this should not be treated as a bzrtools bug because it's a packaging bug: the installer should provide gnuwin32 patch

Here's what happens when running bzr patch:
E:\tomdroid\threading-improvement>bzr patch noNotesMsgFix.patch
bzr: ERROR: Error invoking patch: No such file or directory

After installing gnuwin32 patch (taken from http://gnuwin32.sourceforge.net/packages/patch.htm) and adding it to PATH:
E:\tomdroid\threading-improvement>bzr patch noNotesMsgFix.patch

It worked!

Thanks Olivier Bilodeau,

After installing gnuwin32 patch (taken from http://gnuwin32.sourceforge.net/packages/patch.htm) and adding it to PATH:
It worked!

On windows 7
===========

I've done all the above suggested steps (adding gnuwin patch utility on PATH) and still it failed.

TO make it work:

Start cmd as Administrator and then do bzr patch <patch file>. This should work.

[Alexander Belchenko (bialix)]

@Satya: it's possible that your non-admin account has not PATH changes from admin account? To check this start cmd shell as regular user and check output of

set PATH

and then

patch --verison

See http://sourceforge.net/tracker/index.php?func=detail&aid=1890860&group_id=23617&atid=379173 for a windows 7 resolution.

Patch should really get included into bzr though...

[André Bachmann (andrebachmann-dd)]

There is still this problem with Bazaar 2.5.1 for Windows. Using gnuwin32 patch from http://gnuwin32.sourceforge.net/packages/patch.htm and copying patch.exe into the Bazaar directory under C:\Program Files solves this.

[Alvin Penner (apenner)]

This problem still exists.
Running bzr version 2.0.2 on Windows XP.
