* Linux: Bypass glibc's broken open() implementationThiago Macieira2018-07-171-0/+20
| | | | | | | | | | | | | | | | | | | | | | Glibc 2.21 and earlier have a bug that leaves the mode parameter unset when O_TMPFILE is used. So we bypass the glibc implementation and go directly for the syscall. We do this only for 32-bit x86, since of the current, modern platforms, it's the only one that passes parameters on the stack. Technically speaking, the glibc bug applies to all platforms, but it turns out that on all others, it appears to work. By doing this, we have two minor differences: 1) open() is a cancellation point, but syscall() isn't 2) if anyone tries to intercept open() calls via LD_PRELOAD, they're not going to catch Qt's. [ChangeLog][QtCore][QTemporaryFile] Worked around a bug in the GNU C Library versions 2.21 and earlier (used on Linux) that caused temporary files to be created with permissions 000.

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.

* Accept defeat when select(2)ing without a monotonic clockThiago Macieira2013-07-101-6/+2
| | | | | | | | | | | | | | | | We prefer to use the monotonic clock because it's never affected by time jumps (such as the user changing the date, or the system adjusting for any other reasons, including automatic leap seconds). But if a system doesn't have a monotonic clock, we simply accept the regular, real time clock and hope it doesn't jump. This is better than the current code that never restarts a call. The side-effect is that a 30-second select may become a 3630-second select if someone sets the clock back one hour.
