Description Andres G. Aragoneses 2013-10-23 04:29:08 UTC
By using gtk-sharp.sln[1], with MD master as of today (5082d005ef1a51dfe4957af31c92cf9c269a85da), I'm getting these errors in the console:

This used to be caused by submodules, but I believe we have dealt with that case. I'm not sure why this is happening. What is the result from 'git diff' or 'git status' from commandline git?

The interesting thing is that GetVersionInfo is returning a directory *and* a file when we query for just a file.

> What is the result from 'git status' from commandline git?

Right now, this (although not sure if it was exactly this when I reproduced the error):

$ git status
# On branch fix_cairo_leak
# Changes not staged for commit:
#   (use "git add <file>..." to update what will be committed)
#   (use "git checkout -- <file>..." to discard changes in working directory)
#
#	modified:   cairo/Context.cs
#	modified:   generator/GObjectVM.cs
#
# Untracked files:
#   (use "git add <file>..." to include in what will be committed)
#
#	0001-cairo-check-earlier-for-IntPtr.Zero-in-Dispose-bool-.patch
#	generator/obj/
#	out.txt
no changes added to commit (use "git add" and/or "git commit -a")
Comment 3 Alan McGovern 2013-10-23 08:37:19 UTC
Actually maybe the issue is that the 'generated' directory is marked as git ignore but we're recursing into it anyway? Does that sound likely? Is 'gtk-sharpFIXCAIRODISPOSES/gtk/generated' an ignored directory?
Comment 4 Andres G. Aragoneses 2013-10-23 08:52:45 UTC
> Does that sound likely?

Yes, that's why I named the bug like it is :)

> Is 'gtk-sharpFIXCAIRODISPOSES/gtk/generated' an ignored directory?

Yes: https://github.com/mono/gtk-sharp/blob/master/.gitignore#L22
Comment 5 Marius Ungureanu 2014-01-14 05:06:56 UTC
Gitignores should be handled by NGit. Maybe the treewalk is stupider than I thought. Will check it out.
Comment 6 Marius Ungureanu 2014-04-28 10:58:45 UTC
This is fixed now by having a workaround having been applied for #17216.
