dovecot - Mar 2018 - Deprecations for schema.xml and newest Solr version (7.2.x)

Hi,

the schema.xml example provided for dovecot in
/usr/share/doc/dovecot-<verison> does not work anymore with the newest
Solr Version (as I know of 7.2.x) because some field classes and filter
classes are deprecated in this version.

The changes (according to the Solr documentation) would have to be :

In the index analyzer :

<fieldType name="long" class="solr.TrieLongField" />

into

<fieldType name="long" class="solr.LongPointField" />
.........
<filter class="solr.WordDelimiterFilterFactory"
generateWordParts="1"
generateNumberParts="1" catenateWords="1"
catenateNumbers="1"
catenateAll="0" splitOnCaseChange="1"/>

into

<filter class="solr.WordDelimiterGraphFilterFactory"
generateWordParts="1" generateNumberParts="1"
catenateWords="1"
catenateNumbers="1" catenateAll="0"
splitOnCaseChange="1"/>

and because this is used in the index analyzer it has to be followed by

<filter class="solr.FlattenGraphFilterFactory"/>
..............

In the query analyzer :
<filter class="solr.SynonymFilterFactory"
synonyms="synonyms.txt"
ignoreCase="true" expand="true"/>

into

<filter class="solr.SynonymGraphFilterFactory"
synonyms="synonyms.txt"
ignoreCase="true" expand="true"/>
...............
<filter class="solr.WordDelimiterFilterFactory"
generateWordParts="1"
generateNumberParts="1" catenateWords="0"
catenateNumbers="0"
catenateAll="0" splitOnCaseChange="1"/>

into

<filter class="solr.WordDelimiterGraphFilterFactory"
generateWordParts="1" generateNumberParts="1"
catenateWords="0"
catenateNumbers="0" catenateAll="0"
splitOnCaseChange="1"/>
.........

Don't know if you want to mention this somewhere in your docs.

Cheers,
Thomas

Hello List,

I'm facing an issue with dovecot (2.2.27) IMAP? and Outlook as a client. 
I have some users that use
Outlook (2016) as? a client . One of them has a desktop PC in the office 
and a laptop machine
which I've setup some days ago . The user did some work, during the 
weekend, in his laptop
(filling messages into IMAP folders) and to his (and mine) surprise, 
today in the office he saw that none of his
work is reflected on the server. Messages are not where they supposed to 
be .Tomorrow he will bring the laptop
over to check, but I have seen this problem again in the past? again 
with outlook 2016 as a client
(specifically I've had a user which during work he was deleting or 
renaming folders which appear fine
on his copy of outlook (ost) but not on the server). Anyone has any 
experience with dovecot and outlook
and related problems ?


thanks in advance
George

What came to my mind : are there any changes needed on the dovecot side?

Esp. because there is also a field type change in it....

i have no Outlook 2016 to test but if you setup is right
no trouble should come up, however simply look in the dovecot log files
what your user did, perhaps he was offline and only thinking that he
synced via imap

by the way ost file may broke any time

Recreate an offline Outlook Data File (.ost)

Some account types, such as Microsoft Exchange Server, use an offline
Outlook Data File (.ost). This type of data file is a copy of
information saved on your mail server. If you encounter problems with an
offline Outlook Data File (.ost), the file can be deleted and recreated
by downloading a copy of your items again. We don't recommend repairing
an offline Outlook Data File, so if your offline data file isn't usable,
you should recreate it.
