Il y a quelques jours, Unixgarden a publié sur son site un ancien article que j’avais écrit pour Linux Pratique, qui visait à présenter Sylpheed-Claws — qui ne s’appelait pas encore Claws Mail :-)

Voici l’article. Ça me fait de vieux souvenirs, je l’ai écrit entre la version 1.9.14 et 1.9.15, c’est à dire début octobre 2005. Le canal IRC était #sylpheed, sur IRCNet. On avait encore le plugin ClamAV, pas encore de plugin PDF re-disparu depuis, et les plugins TNEF Parser, SpamReport, S/MIME, RSSyl, GtkHtmlViewer, AttRemover, AttachWarner et Archiver n’existaient pas encore. On a fait du chemin :-)

It’s been a long time since I last blogged! I’ve been really busy with real life…

As you may know, dear reader, my wife (Clo) is pregnant and we’ll have a baby soon (in about 50 days !), so we’ve been preparing stuff in advance. Over the last monthes, we’ve redone the floor in the future baby’s room, created cupboards, painted things, we’ve boughtfurniture , we’ve moved our “office” in the living room, we’ve built a few things, we spent time in baby stores to make lists, see what we needed, buy a few things, etc.

Now we’re almost ready, so we’re waiting :-)

Also, there’s been a whole lot of people at home to visit us – both of my sisters, Clo’s brother, my mother, Clo’s parents, … Very nice! If only we knew we’d just have to make babies to bring them over! ;-p

Yes, I’ve been linking to Clo’s blog everywhere. Not my fault if she blogs more than me!

On the Claws Mail front, I’ve put some days off to use and, following the announce of the GTK team of GTK+3, I’ve removed every fucking deprecated line in our source code and rewrote code that worked; just because the GTK+ guys can’t be bothered with keeping deprecated code around, I’ve rewritten about 10.000 lines, I think. Thanks, dudes. We’ve also been able to fix a good number of bugs, and added support for client SSL certificates.

Maybe we’ll release soon…

“These developers seem to have their priorities in the right place.”

Jonathan Corbet of LWN published last week a review of Claws Mail. I’m quite happy about what he says, his review is quite positive and, as I like his work a lot, I’m pleased!

…rocks.

A user told us on the mailing list that he got a crash. It was SIGXFSZ, File size limit exceeded… Due to the protocol log file growing too much, probably 2 or 4 gigabytes…

The end of his log reads:

IMAP4< 8918737 OK Status completed.

The number at the left is the transaction id of the IMAP protocol, incremented by 1 on every command. That means almost 9 millions commands :-) Our user started Claws Mail on March 10, it crashed on April 17 only due to the log file.

Comforting to read that :-)

A coworker of mine noticed after cleaning up his IMAP folders, that he managed to fill INBOX.Trash with 313.924 mails, and Thunderbird failed utterly at managing that folder.

He then tried to open it with Claws Mail, which succeeded at the second attempt (a wifi disconnect ruining it at 70% the first time – and the 200 MBs of downloaded data got leaked in libetpan, bad).

The second time, the folder opened:

As you can see, the folder is big. We discovered an overflow in the size handling in the process: the mailbox was bigger than 1GB… Claws consumed 670MB of memory with that folder open, but it handled it.

When trying to empty it, we noticed that setting \Deleted flags was really slow, and the server process was using 99.9% CPU on the server. We ended up destroying the mbox on the server.
