Package: libsvn0
Version: 1.2.0-1
Severity: normal
I've been seeing a crash in libsvn0 under the commandline svn client
when attempting to do an export from a local client copy. It's
reproducible many times in a row on the same client copy, but seems to
vary with the state of the client copy or something -- not sure of the
circumstances.
This may be a dupe of #314381 or possibly #316227; they both look
similar but the stack traces in both of those look different.
First a trace, taken with 1.2.0-1 built with DEB_BUILD_OPTIONS=nostrip:
Starting program: /usr/bin/svn export head qpsmtpd-0.31/debian

The actual fault line was clipped by gdb, but appears thusly:
if ((revision->kind != svn_opt_revision_working &&
entry->schedule == svn_wc_schedule_add) ||
(revision->kind == svn_opt_revision_working &&
entry->schedule == svn_wc_schedule_delete))
return SVN_NO_ERROR;
Inspecting those, 'entry' is NULL:
(gdb) p revision->kind
$2 = svn_opt_revision_working
(gdb) p entry
$4 = (const svn_wc_entry_t *) 0x0
'entry' was set NULL by this call to apr_hash_get() in svn_wc_entry():
if (dir_access)
{
apr_hash_t *entries;
SVN_ERR (svn_wc_entries_read (&entries, dir_access, show_hidden, pool));
*entry = apr_hash_get (entries, entry_name, APR_HASH_KEY_STRING);
}
else
*entry = NULL;
stepping to which:
759 *entry = apr_hash_get (entries, entry_name, APR_HASH_KEY_STRING);
(gdb) p entry_name
$13 = 0x808f6b8 "foo"
(gdb) n
765 }
(gdb) p *entry
$14 = (const svn_wc_entry_t *) 0x0
The export had created a couple of files successfully in the export tree. The
one it was working on, "head/foo" was a test file I created, checked in, then
deleted and commited in an attempt to reproduce the problem. So far all the
instances of the crash I've seen have been associated with points in the
export where it was about to touch a file svn-deleted from that particular
client.
An strace of the export:
http://devin.com/cruft/svn-crash/svn-strace.log
A tarball of the client (28k):
http://devin.com/cruft/svn-crash/working-copy.tar.bz2
A fragment of a dump of the repository, with the only two changes ever to
touch the file on which the crash occurred (one creating, the other deleting):
http://devin.com/cruft/svn-crash/repo-dump-excerpt.txt
Hope this is useful. I'll try to keep the testcase intact if you need more
data.

Changes:
subversion (1.2.3a-1) unstable; urgency=low
.
* Welcome the Debian Subversion Team (Closes: #322257)
.
[ Guilherme de S. Pastore ]
* New upstream release (Closes: #320417)
- tarball repackaged without svnbook, as it's licensed under
a non-DFSG-free license (Closes: #215083, #218185, #314154)
- fixes export segmentation fault with versioned items in
"deleted" state (Closes: #314381, #316133, #316227, #320572, #324037)
* debian/compat:
- bump to debhelper compatibility version 4
- no longer export DH_COMPAT from inside debian/rules
* debian/control:
- dropped auto-generation with m4
- dropped build-dependency on quilt
- bump to Standards-Version 3.6.2 with no changes
- removed Conflicts/Replaces on all packages not present in
stable anymore (Closes: #310519)
* debian/patches/ltmain.sh.patch:
- removed; applied upstream
* debian/patches/kaffe-cast.patch:
- removed; broken and unnecessary
* debian/subversion.doc-base.book:
- removed; the book is no longer present
* debian/README.Debian:
- Removed; was doing the work of a package description, and
mentioned the (removed) svnbook
* debian/python2.3-subversion.README.Debian:
- Renamed from pythonX.Y-subversion.README.Debian, we longer
use that auto-generation stuff
* debian/rules:
- tiny fixes to unbreak the build process
- include simple-patchsys.mk from CDBS instead of using quilt;
it was too complex for our needs
- fixed detection of tarballs, as to not get confused by CDBS
auto-generated lists, which would cause the build to fail
- no longer do any magic to auto-generate debian/control and
python related documentation; too complex for too little gain
- set LANG to C, otherwise the build may fail because of tests
failing for not being able to recognize strings returned by
some tools
- no longer do any magic to support builds on pre-sarge
environments; the package is already complex enough without
supporting old cruft unnecessarily
* Removed packaging documentation, as it was pretty much outdated
* Removed maintenance scripts from the package; left them
on the 'tools' section of the repository on svn.debian.org
.
[ David Kimdon ]
* Do not install vc-svn.el (closes: #314213, #315100, #324633)
* Autoload psvn.el by default. (closes: #223303, #235905, #305953)
* Remove hard-coded DEB_BUILDDIR from debian/rules.
* Enable javahl bindings by default (closes: #271125, #323839)
.
[ Peter Samuelson ]
* debian/patches/l10n-segfault.patch:
- fixes a "svn add" crash in the es, fr, it, pl, pt_BR and zh_TW
locales (Closes: #316143, #323376, #326079)
* debian/patches/rpath.patch:
- port to subversion 1.2.x and reenable (work in progress, suppresses
most rpaths)
* debian/lintian-overrides: new file for binary package overrides
* debian/rules:
- support DEB_BUILD_OPTIONS=noopt
- invent a DEB_BUILD_OPTIONS=notest to disable the test suite more
easily
- the INSTALL file is redundant, do not install it in /usr/share/doc
- change #!/usr/bin/env python to #!/usr/bin/python2.3 in assorted
scripts
- split and install lintian-overrides to appropriate packages
- minor cruft removal
