Hi,
In ee9be06 (perl: detect new files in MakeMaker builds, 2012-07-27)
there is a step to detect if there has been an update to the PM.* files,
however it appears that the logic is inverted in the comparison.
I need some extra eye's on this to be sure I have it right (I'm trying
to debug an old Windows breakage...).
The resultant output of a make dry run included (on my m/c)..:
find perl -type f -name '*.pm' | sort >perl/PM.stamp+ && \
{ cmp perl/PM.stamp+ perl/PM.stamp >/dev/null 2>/dev/null || mv
perl/PM.stamp+ perl/PM.stamp; } && \
rm -f perl/PM.stamp+
make -C perl PERL_PATH='/usr/bin/perl' prefix='/c/Documents and
Settings/Philip' perl.mak
Shouldn't it be `{ ! cmp ` so that when the files are not identical, the
move is performed?
https://github.com/git/git/blob/ee9be06770223238c6a22430eb874754dd22dfb0/Makefile#L2097
the code is now at https://github.com/git/git/blob/master/Makefile#L1697
I'd guess that this was something that was tricky to test as once it
works it stays working.
On a clean Msysgit development install the PM.stamp file does not exist
and the cmp exits with error code 2, while identical files return 0.
Msysgit list also copied should someone there have seen this before.
