The CI VIP images were built with NUM_FILES, RTP_FD_NUM_MAX and
HRFS_DEFAULT_MAX_FILES at 300. That is too tight for the Qt autotests.
A single test binary runs several style suites in one RTP, and each Qt
thread's event dispatcher costs two descriptors for its wakeup pipe, on
top of windows, the QML disk cache on /ram0 and test data read over NFS.
tst_qquickpopup exhausted the per-RTP descriptor table roughly five
sixths of the way through its run and aborted with
QFATAL : QEventDispatcherUNIXPrivate(): Cannot continue without a
thread pipe
which is pipe() failing for want of a free descriptor.
NUM_FILES is the kernel-wide table, shared with the SSH daemon, the NFS
client and the serial console, so the same exhaustion starves those
services: the guest stops answering SSH, the test runner cannot reach it
any more and has to reboot the emulator. tst_qquickmenu wedges its guest
the same way.
Raise all three parameters to 1000. Descriptor table entries are a few
tens of bytes, so the memory cost is negligible on the emulated targets,
and the value stays well below FD_SETSIZE (2048) for any code that still
uses select(); Qt itself polls. This leaves an estimated two to three
times headroom over the peak demand of the heaviest test binary, which
is enough to stop the limit being the binding constraint while keeping a
genuine descriptor leak visible rather than merely delayed.
Fixes: QTBUG-150363
