memory use
by Cor Bosman 29 Jun '09

29 Jun '09

Hi devs, just wondering if this is normal: Jun 29 16:36:03 roundcube-test roundcube: PHP Fatal error: Allowed memory size of 104857600 bytes exhausted (tried to allocate 17100392 bytes) in /data/WWW/roundcubemail-2493/program/lib/Net/SMTP.php on line 831 This is a 12MB attachment. That shouldnt be needing a total memory footprint of 100+ MB. I had to move our memory limit up to 200MB just to be able to send a 12MB attachment. Regards, Cor _______________________________________________ List info: http://lists.roundcube.net/dev/

One time ticket auth and imapproxy
by Robert King 26 Jun '09

26 Jun '09

Folks, I'm experiencing a very odd issue with a custom plug-in using the authenticate hook. Here at our university we use a Web based single sign on authentication called CAS (http://www.jasig.org/cas). I am trying to write a plug-in to allow CAS to work with Roundcube proxying a connection through imapproxy (http://www.imapproxy.org/). The normal operation for authentication for IMAP by CAS service is to get a one time use CAS ticket for every authentication. Since RC stores and reuses the initial password CAS cannot work in direction connection to the IMAP server. This is not an issue because when we proxy through imapproxy, it holds open the imap connection by password/username combination. So everything should be working great and superficially it seems okay, that is until you try and delete an e-mail. It seems that a delete will call the authenticate hook again and grab a new CAS ticket. The new CAS ticket breaks the imapproxy connection identifier because the password is now different. In turn this causes rc to have a "lost imap connection" error. The way I look at it I have 2 possibilities: 1. Figure a way out to only request the CAS ticket once in the plugin. I'm guessing do a check for existing ticket before requesting. This is the quick fix, but feels like a "duct tape" solution for what might be a larger issue in extending RC for alternative authentication mechanisms. 2. Extend RC so that instead of caching a password, it uses a password recall function that can has an exec handler for custom plug-ins $rcmail->auth->getpass() returns a clear text password and has an exec handler for password return. Default it would be an abstraction of the decrypt session password to keep current functionality The value with option two is it would allow plug-in authors to authenticate to peripheral services like managesieve with out limiting alternative authentication methods. I've included the current sort of working plugin for anyones interest. -- Robert King System Administrator Computing & Communications Memorial University --- 8< --- detachments --- 8< --- The following attachments have been detached and are available for viewing. http://detached.gigo.com/rc/BK/UGmCcQQp/casauth.php Only click these links if you trust the sender, as well as this message. --- 8< --- detachments --- 8< --- _______________________________________________ List info: http://lists.roundcube.net/dev/

Password plugin and virtuser plugin ideas
by A.L.E.C 25 Jun '09

25 Jun '09

We have a few plugins for password change using different methods for saving new password, but all of them have the same UI. I think it would be better for localization and future maintenance to join them into one plugin with many drivers. We need one function for password change, so we can do this as simple as possible. Let's add drivers/ directory with files sql.php, sasl.php, etc. and config option 'password_driver'. So, everyone just could add his own driver function. My second idea is to create hooks for rcube_user's email2user and user2email functions. Then we could move current virtuser_* features into 'virtuser' plugin. This plugin should also work as password above with drivers for file, sql, or any callback. -- Aleksander 'A.L.E.C' Machniak http://alec.pl gg:2275252 LAN Management System Developer http://lms.org.pl Roundcube Webmail Developer http://roundcube.net _______________________________________________ List info: http://lists.roundcube.net/dev/

slow messages deleting - read_when_deleted being a performance killer
by darklight 24 Jun '09

24 Jun '09

Hi, one note before you continue reading: I'm not familiar with xdebug yet - so you may need to re-verify me findings. also this mail is not a wish to immediately fix some performance-lag, but more some info to the developers/project managers so they can plan correctly :) because I was interested.. I installed xdebug today [1] so.. I was cleaning up my mailbox and I deleted 200 messages (at once) according to firebug this took ~60 seconds which is quite much... then I did some tests... after checking xdebug's profiler output I found something strange: there were 745 queries made by rcube_mdb2->query (which calls _query and this calls the real MDB2 stuff...) 745 queries - and I just profiled the click on the delete button (NOTE: the at this point the messages were in folder X and now they were moved to "Trash") NOTE: there was one huge call to rcube_imap->set_flag() which is because I have $rcmail_config['read_when_deleted'] = TRUE; in my config maybe this can also be optimized (not sure if it can be - but this should have a lower prio) also read_when_deleted s a real performance-killer, I'll try to explain later small break here: as I had message caching enabled I wanted to check if really all messages were in my (MySQL) DB.. looked fine after like 10 seconds (deleting was still being done by roundcube) I refreshed the phpMyAdmin page... and what was that? now there were less messages in the table than before.. - even if they were just moved to "Trash" now.. I waited some seconds - and the row count started to rise again let's try to explain so many database queries (NOTE: keep in mind I had read_when_deleted enabled): when user deletes message 1 from mailbox X the following happens: * $IMAP->set_flag($uids, 'SEEN'); reads and deletes all messages from the caching table... that already makes 400 queries * (message being moved through IMAP) * (message being parsed through IMAP) * message being inserted into the cache table (in the DB) again - that makes another 200 queries -> we're at a total of 600 now plus some others (had no time yet to fully check this) now.. I'm pretty sure that set_flag kills so much performance because it removes the messages from the cache. wouldn't it be easier to just update the header column in the database? (ok, I see it's needed that you unserialize the field.. change some value, then serialize it again and I'm not sure if that costs even more time) also move_message() should do the same, currently it just gets the mail from the caching table and removes it from there (if it exists) - later it has to be inserted into the DB again I may do some more tests later.. feel free to suggest other parts which I could profile :) Regards, Martin [1] http://www.xdebug.org/docs/ _______________________________________________ List info: http://lists.roundcube.net/dev/

SORT (ARRIVE)
by Cor Bosman 24 Jun '09

24 Jun '09

Hi all, ive seen several requests on the mailinglist and forums concerning sorting by internaldate. Looking through the code there seems to be pieces of code to facilitate this, but either I cant find the way to actually set this, or it's not finished. For many imap servers a SORT (ARRIVE) is orders of magnitude faster as all you need to do is stat() the files. For SORT (DATE) you need to open every single email (which can be tens of thousands), find the Date header, then sort all of them. And all so you can find the 50 messages roundcube wants to show. I have a lot of experience with the customer side of this setting as we have this set in our current webmail solution (squirrelmail). In practice there is a percentage of customers that dont like sorting by arrival date. They just dont understand why an email with an obvious date thats older is sorted above an other email. So we have this configurable, with a default of arrival date. That way you can accommodate people that dont like this, while at the same time benefit from the bulk of people that dont care. It should be trivial to add a user-configurable option in roundcube to allow sorting by arrival date. Id be more than happy to make a patch. Would this be something of use to RC?

Re: [RCD] Possible violation of GPL
by till 23 Jun '09

23 Jun '09

Hey Nik, I am not sure if the GPL requires that. AFAIK, the GPL requires Linux Magic to distribute the source code of their webmail when they sold it to a customer. They are not allowed to encrypt the source, etc.. Furthermore, the GPL requires them to keep the copyright on all source files, etc.. Last but not least -- customers of Linux Magic are allowed to put the webmail app on BitTorrent or whatever. Thanks to the GPL. ;-) You may distribute it for free and they couldn't do anything against it. It really looks like they used at least our icon set, and I'm not sure if they are allowed to do that. That might be a direct violation of another license that was granted to the RoundCube project. Do you know anyone who purchased it so we can double-check that? Till P.S. I cc'ed our developer mailinglists. On Wed, Jun 24, 2009 at 1:08 AM, Nik Dahl<nik(a)nwnexus.com> wrote: > I received a sales call from a company called Linux Magic.

Roundcube integration developer required for hire
by Support 23 Jun '09

23 Jun '09

Hello I asked the list moderator if it was ok to post this to the group. We have an entry-level CRM application and would like to integrate Roundcube into it. We have the source code but have since moved on from the initial develop who developed the application. They did this using a very basic text based email engine, which does not have the functionality we require. I have a looked at a number of webmail apps but Roundcube meets our requirements. What we would need would be to be to tie the address book into our contacts sections, ideally we would like the webmail interface to sit within our application. We do not expect to get this service for free (L) and will come to a commercial arrangement with the developer(s) who can help us out. Regards and thanks for everyone's time Hey David, feel free to post to the developer mailing list. That's the easiest way to get some people involved. :-) Till On Tue, Jun 23, 2009 at 12:34 PM, <depstein(a)zero27.co.za> wrote: > Hello > > We are looking at integrating roundcube into an entry CRM application > we have developed - where do you think I could locate a developer who > could do this - I was thinking of posting to dev(a)lists.roundcube.net. > - would this be appropriate? > > Thanks > > David > _______________________ David Epstein _______________________________________________ List info: http://lists.roundcube.net/dev/

replacing native javascript prompt() with Impromptu (jQuery)
by darklight 21 Jun '09

21 Jun '09

Hi, as ticket #1485135 [1] suggests, javascript's native prompt() should be replaced with a custom one. I did a bit of research and I found Impromptu [2] seemed to do this job quite well. after some fiddling with the code I managed to get a nice-looking (at least I think so -> but that doesn't count as I fail at any design/graphics tasks) prompt dialog. A screenshot of it can be seen under [3] my only problem is: to get this working, I had to refactor some code in app.js (not much, but still enough that it could break something :)) Because of this I'm asking for someone who could review my code and suggest what could've been done better. A patch against svn trunk is provided under [4] PS: I also think that the milestone for the ticket should be set to 0.4-beta, as it requires a bit more work than just replacing one line in app.js Regards, Martin [1] http://trac.roundcube.net/ticket/1485135 [2] http://trentrichardson.com/Impromptu/index.php [3] http://img5.abload.de/img/rcppuje3.png [4] http://pastebin.ca/1467910 _______________________________________________ List info: http://lists.roundcube.net/dev/
