987535 - Deploy a python2.7.exe executable to windows build slaves

Status: RESOLVED FIXED

(Infrastructure & Operations :: RelOps: General, task)

Description

[Mike Hommey [:glandium]]

On Linux build slaves, "python" is system python 2.6.something, and "python2.7" is python 2.7. On Windows build slaves, "python" is python 2.7 and "python2.7" doesn't exist. MozillaBuild 1.8+ comes with a "python2.7.exe" executable. Using "python2.7" is a common "reliable" way to launch a python 2.7 script, it would make things easier in bug 980117 if Windows slaves had a "python2.7.exe" executable. It can just be copied from the already existing "python.exe".

I just wanted to check. We want to rename C:\mozilla-build\python27/pyhton.exe to C:\mozilla-build\python27\pyhton2.7.exe?

Comment 3

[Amy Rich [:arr] [:arich]]

They want to copy C:\mozilla-build\python27\pyhton.exe to C:\mozilla-build\python27\python2.7.exe

(copy, not move, and typo corrected).

Comment 4

[Amy Rich [:arr] [:arich]]

well, one of two typos corrected:

C:\mozilla-build\python27\python.exe to C:\mozilla-build\python27\python2.7.exe

Just copy. There are too many things that call "python" to remove it.

There is now a GPO in place to do this. The Windows build slaves should start picking up the changes shortly.

Comment 7

[Mark Cornmesser [:markco]]

This is being done as a file copy added to the file_mozilla_build GPO. The location of the source file is the files/python2.7 in SYSVOL.

Comment 8

[Ed Morley [:emorley]]

I'm presuming on each update of Python in Mozilla-Build, upon rollout of that new version of Mozilla-Build we'll need to re-copy python.exe -> python2.7exe? Or will the GPO do that automatically for us?

Comment 9

[Mike Hommey [:glandium]]

Presumably, new versions of Mozilla-Build come with both files.

Comment 10

[Ed Morley [:emorley]]

Ah yeah sorry I hadn't seen Mozilla-Build copies the file as part of packaging (the default Python windows MSI doesn't bundle the versioned binaries):
