I just did $ git-svn init http://svn.wikimedia.org/svnroot/mediawiki/trunk/phase3 $ git-svn fetch -r 2991:3122 and git-svn went into an endless loop, repeatedly downloading and adding the same files from r2992 over and over again. The bad revision can be viewed here: http://svn.wikimedia.org/viewvc/mediawiki?view=rev&revision=2992 It adds ~1000 files (mostly small images). I can check out this revision just fine using the svn command line client. I found this problem while cloning this repo a while ago, using a slightly older version of git (probably 1.4.3, don't remember exactly). In this repo, some directories appeared in the latest revisions which were deleted a long time ago. You can temporarily browse this repo here: http://misc.j-crew.de/cgi-bin/gitweb.cgi?p=mediawiki.git HEAD contains the dir Smarty-2.6.2, which was removed in SVN r3122. Strangely, my repo misses all commits between r2991 and r3822. You can see the gap at http://misc.j-crew.de/cgi-bin/gitweb.cgi?p=mediawiki.git;a=shortlog;h=49e761ba51ee0d0a698999451134acbf2e078c03 I didn't notice any strange errors while cloning, but I had to abort and restart git-svn a few times, so maybe there was some error there? Anyway, I figured I didn't need the _whole_ history, so this is nothing urgent, but I thought I should report it. ``` ## Eric Wong, 2006-12-20 01:36 Subject: Re: Bug: git-svn fails on Mediawiki SVN repo r2992 Message-ID: <20061220013634.GA3901@localdomain> URL: https://gitlist.dev/e/20061220013634.GA3901%40localdomain In-Reply-To: <20061219235312.GB12756@thorium2.jmh.mhn.de> ``` Thomas Bleher wrote: > There is some problem between git-svn (v1.4.4.1.gad0c3) and MediaWiki > SVN when cloning their repo. > > I just did > $ git-svn init http://svn.wikimedia.org/svnroot/mediawiki/trunk/phase3 > $ git-svn fetch -r 2991:3122 > and git-svn went into an endless loop, repeatedly downloading and adding > the same files from r2992 over and over again. I'm not sure that it was 'endless', just unnecesarily repeating itself. commit 6173c197c9a23fa8594f18fd2c856407d4af31c1 (included in 1.4.4.2) should have fixed your problem... > The bad revision can be viewed here: > http://svn.wikimedia.org/viewvc/mediawiki?view=rev&revision=2992 > It adds ~1000 files (mostly small images). > I can check out this revision just fine using the svn command line > client. The latest git-svn in git.git now bundles all the changed files into a delta on the server side; and is significantly faster over most network connections as a result. > I found this problem while cloning this repo a while ago, using a > slightly older version of git (probably 1.4.3, don't remember exactly). > In this repo, some directories appeared in the latest revisions which > were deleted a long time ago. > > You can temporarily browse this repo here: > http://misc.j-crew.de/cgi-bin/gitweb.cgi?p=mediawiki.git > HEAD contains the dir Smarty-2.6.2, which was removed in SVN r3122. > Strangely, my repo misses all commits between r2991 and r3822. > You can see the gap at > http://misc.j-crew.de/cgi-bin/gitweb.cgi?p=mediawiki.git;a=shortlog;h=49e761ba51ee0d0a698999451134acbf2e078c03 > > I didn't notice any strange errors while cloning, but I had to abort and > restart git-svn a few times, so maybe there was some error there? Hmm, it looks like you ran something like: git-svn fetch -r0:2991 and then something along the lines of: git-svn fetch -r3822:HEAD Is that what happened? Looking at the pre-delta git-svn code, it seems that using -r with fetch at any time other than the initial fetch will result in botched history... -- ``` ## Thomas Bleher, 2006-12-20 09:37 Subject: Re: Bug: git-svn fails on Mediawiki SVN repo r2992 Message-ID: <20061220093736.GA5402@thorium2.jmh.mhn.de> URL: https://gitlist.dev/e/20061220093736.GA5402%40thorium2.jmh.mhn.de In-Reply-To: <20061220013634.GA3901@localdomain> ``` * Eric Wong [2006-12-20 02:36]: > Thomas Bleher wrote: > > There is some problem between git-svn (v1.4.4.1.gad0c3) and MediaWiki > > SVN when cloning their repo. > > > > I just did > > $ git-svn init http://svn.wikimedia.org/svnroot/mediawiki/trunk/phase3 > > $ git-svn fetch -r 2991:3122 > > and git-svn went into an endless loop, repeatedly downloading and adding > > the same files from r2992 over and over again. > > I'm not sure that it was 'endless', just unnecesarily repeating itself. > commit 6173c197c9a23fa8594f18fd2c856407d4af31c1 (included in 1.4.4.2) > should have fixed your problem... It fetched every file at least three times, and I had to kill it after that, it had been running for over an hour already. I just retried with current next, and it's _much_ faster, under one minute now for this particular revision. So consider this problem solved, and thanks a lot! > > The bad revision can be viewed here: > > http://svn.wikimedia.org/viewvc/mediawiki?view=rev&revision=2992 > > It adds ~1000 files (mostly small images). > > I can check out this revision just fine using the svn command line > > client. > > The latest git-svn in git.git now bundles all the changed files into a > delta on the server side; and is significantly faster over most network > connections as a result. Yeah, this is a huge gain. > > I found this problem while cloning this repo a while ago, using a > > slightly older version of git (probably 1.4.3, don't remember exactly). > > In this repo, some directories appeared in the latest revisions which > > were deleted a long time ago. > > > > You can temporarily browse this repo here: > > http://misc.j-crew.de/cgi-bin/gitweb.cgi?p=mediawiki.git > > HEAD contains the dir Smarty-2.6.2, which was removed in SVN r3122. > > Strangely, my repo misses all commits between r2991 and r3822. > > You can see the gap at > > http://misc.j-crew.de/cgi-bin/gitweb.cgi?p=mediawiki.git;a=shortlog;h=49e761ba51ee0d0a698999451134acbf2e078c03 > > > > I didn't notice any strange errors while cloning, but I had to abort and > > restart git-svn a few times, so maybe there was some error there? > > Hmm, it looks like you ran something like: > > git-svn fetch -r0:2991 > > and then something along the lines of: > > git-svn fetch -r3822:HEAD > > Is that what happened? Nope. I just ran "git-svn fetch" repeatedly, and stopped it a few times with ^C (the import was running for several days, and I had to turn off the computer inbetween). Maybe something broke there? Anyway, it's working now, so I think we can consider this problem solved. Thanks, Thomas ```
