The signal handler essentially calls gettimeofday (not on the approved list but time is) and sets a couple of variables (current 64-bit microsecond time, stackLimit). But it does not preserve errno. I don't want to avoid calling gettimeofday and can see no harm in it; it's equivalent internally to time providing it doesn't use its TIMEZONE arg (which it doesn't). But the signal handler /doesn't/ preserve errno and doing so is a very good idea and easy to do. Thanks. > Andres. > >

Re: [Pharo-project] PHP Fog ...

by Steven Baker

About 6 months ago I shelved a project for doing Heroku-style deployments from Pharo to Seaside. Perhaps I should dig out my backup and pick it up. I thought I was the only one that might want this, and I got caught up with some issues serializing and sending objects over the network. So that's my first question: what's the best way to serialize and send an object over the network? Would it perhaps be better to just tell the deployed image to use Monticello to update? Can Monticello roll back in case of error (so it can be headless)? -Steven On Tue, Jan 11, 2011 at 6:36 AM, Geert Claes <geert.wl.claes(a)gmail.com> wrote: > > > Nick Ager wrote: >> >> there's always EC2 and Gemstone: http://www.vimeo.com/18375790 >> > > Yep, I reckon the screencast you made is great Â ... but ... it's not quite > the same though :) > > -- > View this message in context: http://forum.world.st/PHP-Fog-tp3208657p3209078.html > Sent from the Pharo Smalltalk mailing list archive at Nabble.com. > >

Re: [Pharo-project] ZeroMQ, Mongrel2...

by Stanislav Paskalev

I'd be really interested in such port/binding. Note that as far I can see 0mq provides language bindings through ffi and no direct ports. The porting will require a larger effort and heavy maintenance afterward should some 0mq internals change.

[Pharo-project] ZeroMQ, Mongrel2...

by Geoffroy Couprie

Hello, What would you think of a ZeroMQ frontend to Pharo? I was playing with ZeroMQ, and more specifically the Mongrel2 web server, and I thought that would be cool to use it, but the only reference of ZeroMQ and Smalltalk I saw was about some code from Thomas GagnÃ©, which is not available anymore. Anyhow, would you be interested in a port to Pharo? It looks like the protocol is not really hard to implement. Best regards, Geoffroy

[Pharo-project] Fwd: Alien + Cog VM

Hi everyone, I'm using Alien libraries in Pharo 1.1 and I'd like to use this one in Pharo 1.2 (Cog VM) but I don't know what classes has been deprecated, where can I found information about it?
