Re: Async HTTP download with Glib event loop doesn't work on windows

[Daniel Kasak <d j kasak dk gmail com>]

I have some old(ish) binaries of Glib::Object::Introspection for Windows. Yes they were a major pain to build. I'd usually point you to my blog ( http://tesla.duckdns.org ) - but it's offline at the moment ... we're renovating the house and my ADLS2, home server, and other things are totally out of action at the moment. If you're interested, I can go and get the server and rescue stuff off it. I also have build instructions that worked when they were written ( 18 months ago ). I tried repeating the process a couple of months back, and there are unfortunately major issues again, and I've kinda lost interest in building for Windows. Anyway, me know if you want Windows and/or build instructions.

Without knowing how AnyEvent works, if the handler involves threads
then calling *any* GTK+ API from different threads than the one that
called `gtk_main()` is going to blow up your application. Even if it
worked in one release, during a specific alignment of planets, or if
you placed the machines in a pentacle drawn in goat blood, there's no
guarantee that it'll keep working. GTK+ simply does *not* support
multi-threaded access of the windowing system resources.

It does not do anything like that. It only uses Glib::Timeout, Glib::IO, Glib::Idle watchers in fairly standard ways.

 

GTK+ and the G* platform has a whole bunch of API to deal with these
cases, like GTask[0]. Sadly, it's not very Perlish because nobody
wrote introspection overrides for it. Additionally, for things like
HTTP requests, there's a whole library called libsoup[1] which
integrates with the GLib main loop.

We're considering libsoup, but it depends on Glib::Object::Introspection for which there are no windows builds (that we know of).

 

Ciao,
