Thus all Hurd servers and libraries are using the old -[[cthreads|hurd/libcthreads]] package that came with [[microkernel/Mach]], -which is not compatible with pthreads. - -Not only does that mean that people hacking on Hurd internals have to deal with -a non-standard thread package, which nobody is familiar with. Although a -[[pthreads implementation for the Hurd|libpthread]] -was created in the meantime, it's not -possible to use both cthreads and pthreads in the same program. Consequently, -pthreads can't presently be used in any Hurd servers -- including translators. - -(Thus it's impossible to use the [Hurd -libfuse](http://www.nongnu.org/hurdextras/#libfuse) with any FUSE modules -depending on pthreads for example.) - -Most of the conversion has already been done in previous efforts (see -[[!GNU_Savannah_task 5487]]) -- but the tricky parts are still missing. - -The goal of this project is to have all the Hurd code use pthreads. Should any -limitations in the existing pthreads implementation turn up that hinder this -transition, they will have to be fixed as well. - -This project requires relatively little Hurd-specific knowledge. Experience -with multithreaded programming in general and pthreads in particular is -required, though. - -Possible mentors: Barry deFreese (bddebian), Samuel Thibault (youpi) - -Exercise: Try to fix one of the outstanding issues with the work done so far. -It's not yet complete, and there hasn't been much debugging yet, so it should -not be too hard to find something needing improvement -- but if you don't see -anything obvious, feel free to talk to us about an alternative exercise task. -- cgit v1.2.3
