Earlier this week, I reported a problem when two case-insensitive files were created, which is a no-no for checkouts on Mac HFS+ or Windows-based platforms [1]. The problem was quickly corrected in CVS (note that _Exit.texi now lives in the attic [2]). But somehow the git repository still thinks that _Exit.texi belongs to the current tree [3], which leads to this confusing state on a case-insensitive clone: $ git pull Already up-to-date. $ git status # On branch master # Changed but not updated: # (use "git add ..." to update what will be committed) # # modified: doc/functions/_Exit.texi # no changes added to commit (use "git add" and/or "git commit -a") $ git reset --hard HEAD HEAD is now at 7464768... Merge branch 'master' of git://git.sv.gnu.org/gnulib $ git status # On branch master # Changed but not updated: # (use "git add ..." to update what will be committed) # # modified: doc/functions/_exit.texi # no changes added to commit (use "git add" and/or "git commit -a") $ git reset --hard HEAD HEAD is now at 7464768...

My plan, once we make the switch, is to set things up so that CVS die-hards can use git-cvsserver for read-only gnulib operations. BTW, just yesterday there was a bug fix in git relating to git-cvsserver: cvsserver: Handle re-added files correctly http://git.kernel.org/?p=git/git.git;a=commitdiff;h=a7da9adb1ff > Earlier this week, I reported a problem when two case-insensitive files > were created, which is a no-no for checkouts on Mac HFS+ or Windows-based > platforms [1].

I suppose that happened because something went wrong with the automated git-cvsimport run. The current procedure is to rsync the CVS repository, use that via git-cvsimport into an existing .git repository, and then to push the result to savannah. Obviously, before we do the final CVS-to-GIT switch, I'll rerun git-cvsimport from scratch, rather relying on the incrementally-built-up one. ``` ## James Youngman, 2007-05-03 21:40 Subject: Re: Problem with case-insensitive file cleanup Message-ID: URL: https://gitlist.dev/e/c5df85930705031440n3b3025dalf566944da6069262%40mail.gmail.com In-Reply-To: <87odl2dnbk.fsf@rho.meyering.net> ``` On 5/3/07, Jim Meyering wrote: > > Earlier this week, I reported a problem when two case-insensitive files > > were created, which is a no-no for checkouts on Mac HFS+ or Windows-based > > platforms [1].

I have had related problems using git-cvsimport with the GNU findutils source base and was eventually reduced to deleting the git repository into which I was pushing the git-cvsimport result. I had added a directory to the CVS repository (findutils/build-aux) and it was not showing up in the target git repository (i.e. the local directory I was specifying as the argument of -C). Fortunately since git is content-oriented (has foo-nature, whatever, insert hand-wave here), once I have repeated the entire cvsimport operation, pushing the regenerated result to the public git repository only required an incremental amount of work (bandwdth). But suffice to say, I do not believe that git-cvsimport is very reliable. People more familiar with git than I point the finger at cvsps, but to be honest I don't know enough about either program to arbitrate. People also pointed me at alternatives to git-cvsimport but they all had one or more of these drawbacks: 1. No support for incremental import 2. No support for tags 3. No support for branches James. ```
