- Fix#4894: Windows (mingw): Unix.select and non-blocking sockets,
add a filedescr.flags_fd in win32unix/unixsupport.h. It contains the
non-blocking status of the associated filedescr and helps to restore
this status after a select.
- Fix#4789: Windows: Unix.select failing with EPIPE error,
Apply patch provided by J. Vouillon
- Fix#4973: Failure "Unknown handle",
Be consistent between Windows and Linux, raise an EBADF Unix_error
for a closed pipe handle.
- Fix#4844: Unix.select bug (triggered if linked against threads),
Apply patch by C. Bauer, replace lpOrig by lpOrigIdx which can survive
a GC collection
For otherlibs/win32unix/{select|windbug}.c:
- Remove Heap* fucntions to allocate/free memory and replace it by
caml_stat_* function, which are more OCaml compliant
- Rework DBUG message, use DEBUG_PRINT rather than #ifdef DBUG... #endif
and use DEBUG variable (more OCaml compliant), also remove dbug_init
functions and use a static variable to replace it (subject to race
condition but this not really important, because every path lead to
same initialization)
- Use a fast start scheme for pipe polling, rather than always waiting
10ms, start by 1, 2, 4, 8 and then 10ms. The 4 first times give select
a chance to a fast answer.
