2013-02-28Add io_select_timeout to the io interfaceRichard Braun
This change fixes a problem that can occur with non-blocking (and also blocking for very short times) select/poll calls. The problem occurs because the timeout is implemented at the client side. For a non-blocking call, this means that (depending on the code path taken in the C library) the client could get a timeout without a full RPC round-trip to the server. Moving the implementation of the timeout to the servers guarantees a full round-trip, and correct results for non-blocking calls. The modifications in this change depend on the availability of the recently added pthread_hurd_cond_timedwait_np function in libpthread. * boot/boot.c (io_select_common): New static function. (S_io_select): Use io_select_common. (S_io_select_timeout): New function which makes use of io_select_common. * console-client/kbd-repeat.c (repeater_select): Add a timeout parameter. * console-client/pc-mouse.c (repeater_select): Likewise. * console-client/trans.c (io_select_common): New static function.

2013-02-25Include <stdlib.h> or <mach.h> where neededPino Toscano
cthreads.h includes both <stdlib.h> and <mach.h>, while pthreads.h does not; with the switch to pthreads, their lack causes prototype compilation warnings for malloc/calloc/free/abort, and mach_task_self/mach_reply_port/etc in few places. * console-client/vga-support.c: Include <stdlib.h>. * libiohelp/iouser-dup.c: Likewise. * libiohelp/iouser-free.c: Likewise. * libiohelp/iouser-reauth.c: Likewise. * libiohelp/return-buffer.c: Likewise. * libiohelp/shared.c: Likewise. * pflocal/connq.c: Likewise. * nfsd/cache.c: Include <mach.h>.
2012-12-17Fix double call to pthread_mutex_unlock in S_socket_connect.Cyril Roelandt
* pflocal/socker.c (S_socket_connect): fix redundant call to pthread_mutex_unlock. There is no need to hold sock->lock to call connq_connect_cancel, and sock->lock must be taken when leaving the if/else blocks.
2012-12-17Make io_select return errorsSamuel Thibault
instead of returning 0 and make clients have to actually read the error. This makes implementing "poll" much easier. Based on Svante Signell's patch. * pflocal/io.c (S_io_select): Return error returned by pipe_wait_readable or pipe_wait_writable. * trans/fifo.c (trivfs_S_io_select): Return error returned by pipe_wait_readable or pipe_wait_writable. Return EBADF on bogus access mode. * trans/new-fifo.c (trivfs_S_io_select): Likewise.
