14:39 <kaustuv> Screw it. Bug filed: http://caml.inria.fr/mantis/view.php?id=5157

14:41 <f[x]> having signalfd would be cool

14:42 * f[x] currently runs a tick timer event to receive signals in a libevent loop

14:42 <kaustuv> I have a binding already, but currently the signalfd_siginfo structure returned by a read() on a signalfd has native signal numbers, and I need Sys numbers

14:43 <f[x]> copy paste ftw!

16:02 <kaustuv> f[x]: http://www.lix.polytechnique.fr/~kaustuv/misc/ocaml-signalfd-0.01.tar.gz if you want to give it a spin. I'll patch it up for extunix later in the week.

16:12 <flux> yes, the ocaml c interface could use some love

16:48 <kaustuv> Docs here: http://www.lix.polytechnique.fr/~kaustuv/misc/ocaml-signalfd-doc/index.html

16:48 <kaustuv> (I had almost forgotten how nitpicky ocamldoc was...)

16:49 <flux> looks nice, if you're into signal handling

16:49 <flux> how much people do that anyway?-)

16:50 asmanur_ has joined #ocaml

16:51 <kaustuv> It's great because you can have a single select() loop in your entire program to cover signals, messages, events, timers, communication, and so on

16:52 <kaustuv> Perfect for the cooperating threads, for example

16:52 <flux> it's nice, true

16:54 <sgnb> FTR, http://ocsigen.org/darcsweb/?r=lwt;a=commitdiff;h=20091117175015-c41ad-29dc525d8d7761583163a309a95413ad65fc3e24.gz

16:55 <flux> how about adding support for non-linux systems in that way?

16:55 <flux> or would it be glitchy..

16:55 DimitryKakadu has joined #ocaml

16:55 <sgnb> the pb was that even on linux, it is not supported everywhere

16:56 <sgnb> (I mean, it was at the time a very recent feature)

16:56 <sgnb> >= 2.6.27 IIRC

16:58 <sgnb> it would be nice if there was a reliable runtime check

16:59 init1 has joined #ocaml

17:02 <kaustuv> Eventually we will be able to set t_0 to be >= 2.6.27. The bigger issue all these nonstandard fds are, well, not standardized.

21:08 <gildor> hcarty: AFAIR, it was to package ocaml-getttext

21:09 avsm has joined #ocaml

21:10 snarkyboojum has quit [Ping timeout: 240 seconds]

21:11 <hcarty> gildor: Ok, thanks

21:12 <hcarty> The package lists you as the maintainer. I'm not sure if there is a way to check who actually added it.

21:21 <gildor> hcarty: have a look in the commit of the svn

21:53 snarkyboojum has joined #ocaml

21:53 <gildor> hcarty: do you plan to use ocaml-fileutils?

21:54 <hcarty> gildor: Indeed!

21:54 <gildor> great

21:54 valross has joined #ocaml

21:54 <gildor> hcarty: don't hesitate to bug me, I plan to do some works on ocaml-fileutils in a mid-term future

21:55 <gildor> hcarty: I will probably try to adapt it to lwt

21:55 <hcarty> gildor: Thank you. I certainly will if anything comes up

21:55 <gildor> hcarty: BTW I answered your bug on the forge

21:55 <hcarty> I have some projects coming up which, I hope, will give me a chance to try out Lwt

21:56 <gildor> lwt won't be required, but there will be a mode where you can use it

21:56 <hcarty> gildor: I replied back :-) Sorry for the poor wording on my part - your reply is exactly what I'm hoping for.

21:56 <gildor> e.g. -package fileutils.lwt

21:57 <gildor> ok, that is great

21:57 <gildor> it is simple to implement and will give me an additional goal when adpatating it to oasis
