This supports running without pthreads, but with code that is made
thread-safe. A Big Switch -- qpthreads_enabled -- enables or disables
all pthread functions. When disabled, all mutex calls become NOPs.

Introduced separate types for qtime_mono_t and qtime_real_t, to
distinguish the time base of a given value.
Revised all users of timeouts so that they are all expressed as
qtime_mono_t values, so are all Quagga monotonic time based.
Revised qpt_cond_timedwait() so that all condition variables use the
same timebase (CLOCK_MONOTONIC if available, by default). Now all
timeout times are qtime_mono_t, and are converted to whatever the
condition variable is set to, if necessary.
Added explicit timeout to mqueue.
Fixed qps_pselect() to zeroise result vectors if no fds are
reported pending -- seems the O/S does not do this.

This allows mutexes to be initialised as recursive.
Required correctly placed setting of _GNU_SOURCE (for gcc).
It is assumed that "config.h" will enable the required pthreads
features -- which are now documented in lib/qpthread.c.
|
| |
|
|
|
|

Added qpt_thread_self().
Initialised output sigset_t before setting it in qpt_thread_sigmask().
|
| |
|
|
| |
Adding qpt_thread_sigmask() and qpt_thread_signal().

New files: lib/qpthreads.c & .h
Encapsulates the Pthreads facilities to be used in Quagga.
Implicitly documents the sub-set of Pthreads being used.
Provides error checking for a number of functions which may return
errors, but are not generally expected to and for whom an error is
treated as fatal.
Could be modified to "null out" the use of Pthreads.
New files: lib/qtime.c & .h
Defines a 64-bit integer time value which is a lot easier to
handle than the usual timespec and timeval structures. (C99
requires a 64-bit integer.)
Provides front ends for gettimeofday() & clock_gettime() which
return 64-bit time value. Also conversions to and from timespec and
timeval.
Provides a monotonic clock for when CLOCK_MONOTONIC is not available.
(This is based on code from Joakim Tjernlund.)
New files: lib/heap.c & .h
Implements a heap data structure closely allied to the vector.
This will be used for timer handling.
Modified: lib/memtypes.c
New memory types for qpthreads structures and for the heap.
Modified: lib/zassert.h
Added explicit "passert" == assert which is not subject to NDEBUG.
Added explicit "nassert" == assert which is subject to NDEBUG.
Added zabort, zabort_errno and zabbort_err for when something has
gone fatally wrong. (Require changes to lib/log.c which are TBD.)
