Finalized SRU template and ran the tests again on a container using the new
upload (built locally).
Works as expected and is reflected in the [Test Case] section.
Uploaded, so setting Fix committed for now.
** Description changed:
- dovecot-lucene in wily (and xenial) crashes immediately when enabled due
- to a bug in the buildsystem which enables use of the Snowball analyser
- when textcat is available but the code is only built when libstemmer is
- available.
+ [Impact]
+
+ * Users get segfaults when using dovecot
+
+ * Root cause is that dovecot-lucene is broken, deprecated and builds
+ its lucene plugin with bad symbols refernces
+
+ [Test Case]
+
+ * sudo apt-get install dovecot-lucene
+ * then enable lucene
+ * sed -ie 's/#mail_plugins = $/mail_plugins = $mail_plugins fts fts_lucene/'
/etc/dovecot/conf.d/10-mail.conf
+ * sed -ie 's/^plugin {$/plugin {\n fts = lucene\n fts_lucene =
whitespace_chars=@./' /etc/dovecot/conf.d/90-plugin.conf
+ * service dovecot reload
+ * doveadm pw -s SSHA256 -p verysecretindeed
+ * see error:
+ Fatal: Couldn't load required plugin
/usr/lib/dovecot/modules/lib21_fts_lucene_plugin.so: dlopen() failed:
/usr/lib/dovecot/modules/lib21_fts_lucene_plugin.so: undefined symbol:
_ZN6lucene8analysis8snowball16SnowballAnalyzerC1EPFiPKvmP6bufferEPKc
+
+ * Instead of crashing with the fix it will report to not have that plugin
+ Fatal: Plugin 'fts_lucene' not found from directory
/usr/lib/dovecot/modules
+
+ * on top we now get also:
+ The following package was automatically installed and is no longer
+ required:
+ libclucene-core1v5
+
+ [Regression Potential]
+
+ * We are removing the dovecot-lucene functionality which some might consider
a regression. But it never ever worked, so it is not a regression.
+ * Therefore there should be no existing (working) setup that regresses by
removing dovecot-lucene.
+
+ [Other Info]
+
+ * Discussion was held on #ubuntu-devel what the right match to "dropping
binary package" is for an SRU and changing it to become an empty package was
the consensus.
+
+
+ ------
+
+
+ dovecot-lucene in wily (and xenial) crashes immediately when enabled due to a
bug in the buildsystem which enables use of the Snowball analyser when textcat
is available but the code is only built when libstemmer is available.
