Thread: https://gitlist.dev/t/11541 ## Dennis Schridde, 2008-01-08 22:25 Subject: git svn fetch segfaults Message-ID: <200801082325.45756.devurandom@gmx.net> URL: https://gitlist.dev/e/200801082325.45756.devurandom%40gmx.net ``` Hello! The following procedure results in a segfault: mkdir org.gna.warzone2100.git cd org.gna.warzone2100.git git --bare init git --bare svn init --use-svnsync-props --stdlayout file:///var/svn/warzone2100/ git --bare svn fetch A full log is attached. If you want any more information, a dump of the SVN repository, etc, just tell me. The last part which seems to be interesting is this one: Odd number of elements in anonymous hash at /usr/bin/git-svn line 1760. r13 = 7f00bbc9c92e5601b158c2cbc572b8e7bdcebe59 (tags/1.10a) Segmentation fault If I do not specify --use-svnsync-prop to "git svn init", it gets past r13 in tags/1.10a. (Note that in the other mail, where I reported about the "Odd number of elements" problem, I used "git svn clone" instead.) I am using these versions: svn, version 1.4.6 (r28521) git version 1.5.4.rc2 --Dennis (Please CC me if you answer, since I am not subscribed.) ``` ## Miklos Vajna, 2008-01-09 00:33 Subject: Re: git svn fetch segfaults Message-ID: <20080109003307.GS29972@genesis.frugalware.org> URL: https://gitlist.dev/e/20080109003307.GS29972%40genesis.frugalware.org In-Reply-To: <200801082325.45756.devurandom@gmx.net> ``` On Tue, Jan 08, 2008 at 11:25:45PM +0100, Dennis Schridde wrote: > mkdir org.gna.warzone2100.git > cd org.gna.warzone2100.git > git --bare init > git --bare svn init --use-svnsync-props --stdlayout > file:///var/svn/warzone2100/ > git --bare svn fetch wget http://svn.kynes.de/warzone2100.bz2 svnadmin create warzone2100 && bzcat warzone2100.bz2 | svnadmin load warzone2100 the rest is the same i get a segfault at the very same place. > If I do not specify --use-svnsync-prop to "git svn init", it gets past r13 in > tags/1.10a. same. > I am using these versions: > svn, version 1.4.6 (r28521) > git version 1.5.4.rc2 $ svn --version svn, version 1.4.5 (r25188) $ git --version git version 1.5.4.rc2.38.gd6da3 thanks, - VMiklos ``` ## Dennis Schridde, 2008-01-09 12:53 Subject: Re: git svn fetch segfaults Message-ID: <200801091353.44630.devurandom@gmx.net> URL: https://gitlist.dev/e/200801091353.44630.devurandom%40gmx.net In-Reply-To: <20080109003307.GS29972@genesis.frugalware.org> ``` Am Mittwoch, 9.

If it is svn executable spawned by Perl that runs git-svn, or libsvn shared object linked to Perl while running git-svn, I suspect testing with different git versions will not be very productive. ``` ## Björn Steinbrink, 2008-01-09 20:53 Subject: Re: git svn fetch segfaults Message-ID: <20080109205354.GA1433@atjola.homenet> URL: https://gitlist.dev/e/20080109205354.GA1433%40atjola.homenet In-Reply-To: <7v4pdmiwo4.fsf@gitster.siamese.dyndns.org> ``` On 2008.01.09 12:14:19 -0800, Junio C Hamano wrote: > Dennis Schridde writes: > > > Am Mittwoch, 9.

Oh well, anyway, just for the record: doener@atjola:~ $ svn --version svn, version 1.4.4 (r25188) doener@atjola:~ $ git --version git version 1.5.4.rc1.11.gd2f82 Björn ``` ## Björn Steinbrink, 2008-01-09 22:15 Subject: Re: git svn fetch segfaults Message-ID: <20080109221508.GB2218@atjola.homenet> URL: https://gitlist.dev/e/20080109221508.GB2218%40atjola.homenet In-Reply-To: <20080109205354.GA1433@atjola.homenet> ``` On 2008.01.09 21:53:54 +0100, Björn Steinbrink wrote: > On 2008.01.09 12:14:19 -0800, Junio C Hamano wrote: > > Dennis Schridde writes: > > > > > Am Mittwoch, 9.

It finished by now, no segfault with --use-svnsync-props.

For me it always segfaulted at r13 in tags/1.10a. I crosses r13 before that already (trunk), but doesn't crash there. I am now recompiling svn,git,perl to create a coredump, will the rerun it and hopefully get some backtraces from the dump. Btw, I am running perl 5.8.8, in case that matters somehow. --Dennis ```
