1.9.0.138.g2de3478.dirty
Hello,
This is my patch for the GSoC microproject #2
I follow the suggestion of Junio to use the strbuf_addf to deal with this thing.
And the usage of strbuf_addf needs to change the function finish_tmp_packfile,
I search all over the source code ($ find .| xargs grep "finish_tmp_packfile")
The following files contains finish_tmp_packfile:
bulk-checkin.c
builtin/pack-object.c
pack-write.c
pack.h
And I do some change to fix them.
I changed my vimrc so that tabs will not be changed into spaces automatically.
And I came across a bug when I was doing my microproject.
position: builtin/pack-objects.c: write_pack_file: if(!pack_to_stdout): first
else in it
warning() function used an uninitialized array, and I changed it to
pack_tmp_name.
Thank you all for all your suggestions.
Cheers,
He Sun
