[pacman-dev] Little hello and pyalpmm announcement

[Dario Freddi]

Hi Markus,

I'm the main developer of Aqpm, a Qt/C++ wrapper of alpm, which is also the 
library behind Shaman. Your project seems great, and I hope somebody will use 
it to make something just as great!

However, I wanted to let you know that at the moment Alpm behaves strangely in 
multithreaded environments. Particularly (I don't know why and I did not 
investigate further), when running package scriptlets the operation will stall 
completely if more than one thread is active.

You might want to consider this in your library, in Aqpm there's no such 
problem as by using PolicyKit, transactions are always jailed in a different 
process which is of course single-threaded, and that's probably the only 
solution.

I would suggest you to make some tests of pyalpmm in multithreaded 
environments, since the highest barrier of alpm in GUI ambits is that it was 
not designed with thread usage in mind. Also have a look at Aqpm, which is 
completely thread-safe, as I jailed alpm as well in its very own thread, you 
might be tempted to adopt a similar solution.

Hope this helped you!
