Using git version 1.5.0.3 on cygwin (available on packages). I am able to do the steps. 1. git init on my source 2. git add . 3. git commit After that, a new file is created for the project and after editing the file. am trying to put into the souce. since it is a new file for my project git repository, am trying to add it but end up with errors as follows. $ git add project/test.c error: bad index file sha1 signature fatal: index file corrupt could you please help me, what am doing wrong? best regards, srinivas. ``` ## Johannes Schindelin, 2007-04-30 11:46 Subject: Re: problem using git on cygwin Message-ID: URL: https://gitlist.dev/e/Pine.LNX.4.64.0704301343020.29859%40racer.site In-Reply-To: ``` Hi, On Mon, 30 Apr 2007, srinivas naga vutukuri wrote: > $ git add project/test.c > error: bad index file sha1 signature > fatal: index file corrupt I could imagine that you do not have "binary mode" default for opening files. However, if you do, maybe your .git/index went corrupt? As a workaround, you could try "git read-tree HEAD" and then "git add" again, but make sure you have a backup of .git/index, since it could be a bug in Git(cygwin) and if so, I'd like to fix it. Ciao, Dscho ``` ## srinivas naga vutukuri, 2007-05-02 04:04 Subject: Re: problem using git on cygwin Message-ID: URL: https://gitlist.dev/e/ace3f33d0705012104r3cf0b99ayb2ec2a69833e6ea1%40mail.gmail.com In-Reply-To: ``` Hi, On 4/30/07, Johannes Schindelin wrote: > Hi, > > On Mon, 30 Apr 2007, srinivas naga vutukuri wrote: > > > $ git add project/test.c > > error: bad index file sha1 signature > > fatal: index file corrupt > > I could imagine that you do not have "binary mode" default for opening > files. > i do't think it is in binary mode when opening the files. I am used vim to create a new file and editing through that. And also am used file format (set ff=unix). > However, if you do, maybe your .git/index went corrupt? > > As a workaround, you could try "git read-tree HEAD" and then "git add" > again, but make sure you have a backup of .git/index, since it could be a > bug in Git(cygwin) and if so, I'd like to fix it. > I have taken the initial index (once repository created, after initial commit) to backup. and followed the above steps. 1. cp index index.orig 2. git read-tree HEAD 3. git add test.c (my new file) But end up with the same errors. Would you think there is a bug in the git working on cygwin ?. I hope would the sequence help you in catching the bug. > Ciao, > Dscho > > best regards, srinivas. ``` ## Jari Aalto, 2007-05-02 11:55 Subject: Re: problem using git on cygwin Message-ID: URL: https://gitlist.dev/e/abwne8y7.fsf%40cante.net In-Reply-To: ``` "srinivas naga vutukuri" writes: > Hi, > > On 4/30/07, Johannes Schindelin wrote: >> Hi, >> >> On Mon, 30 Apr 2007, srinivas naga vutukuri wrote: >> >> > $ git add project/test.c >> > error: bad index file sha1 signature >> > fatal: index file corrupt >> >> I could imagine that you do not have "binary mode" default for opening >> files. > > i do't think it is in binary mode when opening the files.

Please run $ mount And you should see "binmode". Here are examples: D:\cygwin on / type system (binmode) D:\cygwin\bin on /usr/bin type system (binmode) D:\cygwin\lib on /usr/lib type system (binmode) E:\data\src on /usr/src type system (binmode) If not, you need to remount directories with "-b" option. See man mount(1) Jari ``` ## Alex Riesen, 2007-05-02 12:37 Subject: Re: problem using git on cygwin Message-ID: <81b0412b0705020537g485012ffr75d5ee2c7dc600f9@mail.gmail.com> URL: https://gitlist.dev/e/81b0412b0705020537g485012ffr75d5ee2c7dc600f9%40mail.gmail.com In-Reply-To: ``` On 5/2/07, srinivas naga vutukuri wrote: > > On Mon, 30 Apr 2007, srinivas naga vutukuri wrote: > > > > > $ git add project/test.c > > > error: bad index file sha1 signature > > > fatal: index file corrupt > > > > I could imagine that you do not have "binary mode" default for opening > > files. > > > i do't think it is in binary mode when opening the files.

Johannes was referring to binary mode for writing files for _cygwin_ itself, not for files the git has to manage. See "Default Text File Type" in cygwins setup.exe (maybe even follow the link "Read more..."). ```
