Hi Julian,

Thanks for the response, but i have done that too. Infact i tried sneaking
in to scripts responsible for creating the patch and applying the patch,
following is my observation(which i have posted on

i found that when we run 'svn-create-patch', this script executes svn
diff on the png file in one of the iterations. When i tried to do the
same exclusively from cygwin command line and normal command prompt,
svn diff --diff-cmd diff LayoutTests/platform/win/fast/forms/fieldset-legend-

i see that following as the footer
Added: svn:mime-type
## -0,0 +1 ##

And on chasing .Tools/Scripts/svn-apply i found that script is
actually dying because it does'nt get propertyValue(from VCSUtils.pm
file), as the condition in while loop is not getting satisisfied
(while (defined($_) && /$svnPropertyValueStartRegEx/) {). It is
expecting any one of /^   (\+|-|Merged|Reverse-merged) ([^\r\n]+)/
But $_ is ## -0,0 +1 ##.

But since this is a new file it will never be Merged or
Reverse-merged, and i dont see any + or - with mime-type:image/png .

Hence my patch will never go through style bots, and i am sorry for
uploading so many failing patches.

I just want to know if my cygwin settings are wrong? or svn
configuration settings are wrong? or do i have to leave this and find
an alternate method to upload the patch?.

Please kindly let me know what else can be done to upload the patch.

Initially i thought its a svn diff related problem but since everybody is
uploading patches, i  am holding back on that assumption. i tried to look
at change logs for some references on patch, but i found that almost all of
them are using git diff, so it dint help me much.

Can u please  suggest what is the alternative to upload the patch.
