The reason I'm asking is that I see the same problem in that situation, but my svn repo is on a windows box, accessed over svn://url, so I just assumed it was a problem on the remote end (the service dies). But the problem always goes away if I commit the new directory using the svn client before doing git-svn dcommit again.... -- larsh ``` ## Lars Hjemli, 2007-05-11 11:30 Subject: Re: [BUG] git-svn dcommit fails (connection closed unexpectedly) Message-ID: <8c5c35580705110430w12076cfbs527be3c404ea07a5@mail.gmail.com> URL: https://gitlist.dev/e/8c5c35580705110430w12076cfbs527be3c404ea07a5%40mail.gmail.com In-Reply-To: <8c5c35580705110427o4de686e8qdb37f6a2da0043e4@mail.gmail.com> ``` Hmm, your MUA fooled me to reply to the wrong people...

There seem to be a correlation, yes. Usually, simple commits will work fine, and when I do something complex with the filesystem, it breaks. I don't remember all the cases where it broke, but at least, last time, it was about a new file in a new directory, yes. -- Matthieu ``` ## Eric Wong, 2007-05-13 17:17 Subject: Re: [BUG] git-svn dcommit fails (connection closed unexpectedly) Message-ID: <20070513171707.GA14024@muzzle> URL: https://gitlist.dev/e/20070513171707.GA14024%40muzzle In-Reply-To: ``` Matthieu Moy wrote: > Hi, > > I'm using git-svn, which usually works fine, but I occasionally get > this: > > $ git-svn dcommit > A file1 > A file2 > Network connection closed unexpectedly: Connection closed unexpectedly at /path/to/git-svn line 401 > $ > > The failure seems to depend on the commit's I'm pushing, since this is > reproducible when running several times "dcommit" for the same commit, > but the same command also usually works fine on the same repositories > (same git repo, same svn target). > > The svn repository is accessed with svn+ssh://user@machine/path/. Does the patch in http://permalink.gmane.org/gmane.comp.version-control.git/47126 help? If so, I'm not sure why it should be failing sometimes and not all the time. If your local username the same as the username you're using for svn it shouldn't fail for the reason that patch above is needed. Using the native svn or svn+ssh protocol is definitely flakier in my experience, and there are still known issues with connections closing during *fetch*. dcommit is actually a lot more straightforward as it only connects once, whereas fetch can reconnect to different parts of the repo for --follow-parent. > exporting the patch, applying it to an svn checkout, and "svn commit" > works fine. > > Let me know if I can provide any other usefull information for > debugging. > > Thanks, > > Debian etch (stable) > Reproducible with both git 1.5.1.1 and the latest from git: > > $ git-svn --version > git-svn version 1.5.2.rc3.3.ge347 (svn 1.4.2) Which version of SVN is running on the server? -- Eric Wong ``` ## Martin Eisenhardt, 2007-05-13 17:49 Subject: Re: [BUG] git-svn dcommit fails (connection closed unexpectedly) Message-ID: <200705131949.38051.list-receive@mneisen.org> URL: https://gitlist.dev/e/200705131949.38051.list-receive%40mneisen.org In-Reply-To: <20070513171707.GA14024@muzzle> ``` Hi Eric, hi Matthieu, hi list, On Sunday 13 May 2007 19:17:07 Eric Wong wrote: > Matthieu Moy wrote: > > I'm using git-svn, which usually works fine, but I occasionally get > > this: > > > > $ git-svn dcommit > > A file1 > > A file2 > > Network connection closed unexpectedly: Connection closed unexpectedly at > > /path/to/git-svn line 401 $ I ran into that one, too ... :-( > > The failure seems to depend on the commit's I'm pushing, since this is > > reproducible when running several times "dcommit" for the same commit, > > but the same command also usually works fine on the same repositories > > (same git repo, same svn target). I assume that the dcommit runs fine for *other* commits but not for that one that produced the error cited above. In my case, it was simply a problem on my side: I had tried to add a file, that already existed in the repository - and subversion rejected the commit. Of course, it would be nice if git-svn could simply tell the user about his error, i.e., simply copy the output of libsvn or whatever it is using to connect to the subversion repo. Another case where I stumbled upon said error message was when I added an empty (sub)directory to a project in subversion and then used git to track that project. Since git cannot track an empty directory, it did not appear in my git working copy. When I mkdir'd the directory locally (in my git wc) and then tried to add files within that repository, I got exactly the same error as Matthieu. > > Does the patch in > http://permalink.gmane.org/gmane.comp.version-control.git/47126 > help? Not in my case, although this patch resolved the other issue, thanks again btw!

I wouldn't personally mind if somebody taught git to just track empty directories too. There is no fundamental git database reason not to allow them: it's in fact quite easy to create an empty tree object. The problems with empty directories are in the *index*, and they shouldn't be insurmountable. I never wanted empty directories for the kernel, but there is nothing really fundamentally wrong with them either. They do have some problems, which is why I don't particularly like tracking them, but if *not* tracking them causes more problems for people who import from SVN, I could easily see the balance moving towards "let people do it if they want". In fact, I think the subproject support might have made it easier to track directories as empty directory entries. Pretty much every place that got impacted by subprojects would be where empty directory entries would be handled too. In fact, one of the questions when tracking empty directories is whether you should track non-empty directories too. IOW, should we _always_ put the directory entry into the index (even when it's not empty), or should we do it only when somebody explicitly asks for it. I suspect the "always" case would is the right answer (ie a read-tree would always add a directory entry to the index before it starts adding the actual entries in the read-tree) Anybody want to try it?

Just to add my 2 cents: I just had a case where I would have needed empty directories, and it seems reasonable as a workflow: As a group of teachers, one created a skeleton, with stg like ./course/ ./practical-works/day1 ./practical-works/day2 ./exercices/day1 ./exercices/day2 ... He did it with svn, filled in only a few directories, I "git-svn clone"d it, and I got almost nothing! These empty directories are not interesting by themselves, but as a placeholder to add files, I think it's a good thing to have them. -- Matthieu ``` ## Matthieu Moy, 2007-05-14 18:13 Subject: Re: [BUG] git-svn dcommit fails (connection closed unexpectedly) Message-ID: URL: https://gitlist.dev/e/vpqtzuf46k9.fsf%40bauges.imag.fr In-Reply-To: <8c5c35580705110427o4de686e8qdb37f6a2da0043e4@mail.gmail.com> ``` "Lars Hjemli" writes: > Is this happening if you dcommit a file in a new directory?
