So the removal of a .pack file makes sense here - to me, at least. -- Cheers, Ray Chuan ``` ## René Scharfe, 2010-08-06 07:14 Subject: Re: BUG! missing .idx causes .pack to be removed Message-ID: <4C5BB64A.4070601@lsrfire.ath.cx> URL: https://gitlist.dev/e/4C5BB64A.4070601%40lsrfire.ath.cx In-Reply-To: ``` Am 06.08.2010 05:24, schrieb Tay Ray Chuan: > Hi, > > On Fri, Aug 6, 2010 at 1:01 AM, Enrico Weigelt wrote: >> while doing some experiments I've removed the *.idx files and >> ran git-repack - that complained about missing objects and removed >> all *.pack files ! >> >> I'm sure that's a bug - an ugly one ;-o > > IIRC, a .pack file is useless without its corresponding .idx file.

Not sure if it should be done automagically, but the file is not completely useless.

ACK. packfiles are completely self-contained - the index files are only used for lookup and can be created any time (IMHO that's also done automatically on remote transfers). So removing a packfile, just because the index is missing, causes an serious data loss. That's what I'd consider a critical bug! The correct solution would be either recreating the index automatically or at least spit out an big-fat warning. cu -- ---------------------------------------------------------------------- Enrico Weigelt, metux IT service -- http://www.metux.de/ phone: +49 36207 519931 email: weigelt@metux.de mobile: +49 151 27565287 icq: 210169427 skype: nekrad666 ---------------------------------------------------------------------- Embedded-Linux / Portierung / Opensource-QM / Verteilte Systeme ---------------------------------------------------------------------- ```
