* qt_poll: split out into separate file and sanitize buildLouai Al-Khanji2015-12-051-19/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The qt_poll function calls recv to query whether fds marked by select as readable should be marked POLLIN or POLLHUP in the pollfd structure. On many platforms such as QNX this requires extra link-time libraries which were not previously required by QtCore. While the qt_poll function is intended as a fallback mechanism only for those platforms which do not implement poll natively, the function was compiled unconditionally whenever QT_BUILD_INTERNAL was defined, e.g. in developer builds. Additionally the function was included on those systems that define poll in system headers so that configure determines build-time availability, but do not define _POSIX_POLL > 0 or indicate POSIX:2008 compliance via either the _POSIX_VERSION or _XOPEN_VERSION macros. On those systems a sysconf query for _SC_POLL was performed to determine at runtime whether to call the system poll or qt_poll. Both of these cases are in fact counterproductive. In the first case the sole consumer of the function is a single manual unit test. In the second, to my knowledge no platform requires the runtime fallback. Despite that, we were forcing an extra dylib in both cases. Both cases are fixed by 1) moving the implementation into its own file for the unit test to include and 2) dropping the dynamic fallback if configure determines availability of poll at compile-time. This also reverts commit 13777097118c496391d4b9656b95097ac25e4a40, which added -lsocket for QtCore on QNX.

* Add qt_safe_ftok wrapper for ftokLouai Al-Khanji2015-09-301-0/+14
| | | | | | | | | | | | | | | | The ftok function unfortunately can return duplicate keys even for different files if the same project id is used. This is discussed e.g. in Stevens' "Advanced Programming in the UNIX Environment". We want the key to be predictable so we cannot just pass a random number as the project id. To reduce the propability of key collisions we hash the file name with the project number as seed for a predictable value. This is the same approach taken e.g. by Apache, but the real fix is to move away from System V IPC completely once this is feasible on our supported platforms.

* Revamp the CLOEXEC support in QtThiago Macieira2015-07-171-43/+17
| | | | | | | | | | | | | | The pipe2/dup3/accept4 functions and SOCK_CLOEXEC are quite old nowadays on Linux. They were introduced on Linux 2.6.28 and glibc 2.10, all from 2008. They were also picked up by uClibc in 2011 and FreeBSD as of version 10.0. So we no longer need the runtime detection of whether the feature is available. Instead, if the libc has support for it, use it unconditionally and fail at runtime if the syscall isn't implemented.

* Use nanosleep instead of pthread_cond_timedwait for thread sleepingThiago Macieira2012-08-251-0/+1

It's quite likely that they were older, Unix systems we no longer support anyway. nanosleep comes from POSIX.1b-1993, which is merged into POSIX.1-2001, so chances are that it's supported almost everywhere where Qt runs (except for Windows anyway).

* Correctly normalize timevals before calling select()Bradley T. Hughes2011-11-091-4/+4
| | | | | | | | | | | | | | | | When normalizing timevals, we need to bound the tv_usec member to 0-999999 inclusive, otherwise select() may return EINVAL. When rounding timevals to the nearest millisecond in the UNIX event dispatcher, pass the timeval through normalizeTimeval() when returning. As discovered on Mac OS X with tst_QFutureWatcher, starting a 10 second timer would end up calling select() with timeval = { 9l, 1000000 }, resulting in numerous "select: Invalid argument" warnings being printed to the console.
