I track xls by using filter to convert it to gnumeric format. Inside gitconfig [filter "excelbiff"] clean = ssconvert --export-type=Gnumeric_XmlIO:sax fd://0 fd://1 | zcat -f smudge = ssconvert --export-type=Gnumeric_Excel:excel_biff8 fd://0 fd://1 and xls set inside gitattribute While the clean filter works, the smudge filter does not. When git-checkout it said seek error git ckeckout foo.xls However git-show works as pipe to ssconvert git show HEAD:foo.xls | ssconvert --export-type=Gnumeric_Excel:excel_biff8 fd://0 newfoo.xls I guess ssconvert was mistaken to believe that all data has been flushed too soon. I tested with an xls that converted to gnumeric uncompress file size about 10MB and libgsf 1.14.11 PS. for older libgsf it needs to using a temp file to buffer data for ssconvert instead of using fd://0 -- regards, ==================================================== GPG key 1024D/4434BAB3 2008-08-24 gpg --keyserver subkeys.pgp.net --recv-keys 4434BAB3 唐詩019 孟浩然 夏日南亭懷辛大 山光忽西落 池月漸東上 散髮乘夜涼 開軒臥閑敞 荷風送香氣 竹露滴清響 欲取鳴琴彈 恨無知音賞 感此懷故人 中宵勞夢想 -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
