Assert failed in enif_demonitor when called with "NULL-monitor".
Replaced null monitor with separate 'is_active' boolean
and added my_make_monitor_term for printing (to be replaced
with enif_make_monitor_term).
|
|
Asserts failed in debug vm as msg term was built
from mixed ErlNifEnv's.
|
|
Add a quiet mode for ttest which is used when running in
a (terminal) shell.
Moved the esock-ttest script(s) into their own directory.
Minor improvements to the (client) result printout.
Also fixed copyright (end) dates.

The nif callback functions (nif_open) now instead cause an
'nosup' exception if called (instead of badarg).
The basic type uint16_t, uint32_t and int32_t (C99) replaced
"own" (that is, defined by "us") types Uint16, Uint32 and
Sint32.
The point of this is that our Windows build system seems to
be a bit lacking when it comes to types...
Removed "some stuff" that was if-defed. Different solution
when win32 support for sockets has been improved.
Make sure the socket_*.c util modules are not included
in the building for windows.

Using magic refs for big timers caused too large a stress on
the off_heap GC implementation to be viable, so it was never
enable. The code is now broken because of other changes to
we might as well remove it.

Added preliminary, and temporary, windows adaptions.
Basically they amount to letting all nif-callback functions
returning badarg for all calls if on windows (this has
been accomplished by if-defing the nif-code; if win32 then
badarg else do-something).

Its now possible to set a rcvbuf (otp) option value
of {N :: pos_integer(), BufSz :: pos_integer()}.
This value is used for type stream and protocol tcp,
when calling the function recv with length = 0 (zero).
The second value, BufSz, is the actual size of the receive
buffer used when calling the socket recv function, and
the first value, N, is the max number of possible reads
that will be performed (at most), even if there is more
data to read. This is limit the effect of DoS attacks.

to increase the probablity of a nice badarg
from erlang:port_control.
|

The read and write functions now *only* use the isReadable and
isWritable fields, respectively, to decide if the "socket" can be read
from and written to (previously the state field was used outside of
the mutex lock).
Also made it possible to enable / disable test suite groups individually,
via environment variables (ESOCK_TEST_...). Specifically, the ttest
group has been excluded by default (takes to long a time).

Apply type optimizations across local function calls
|
|
This commit lets the type optimization pass work across functions,
tracking return and argument types to eliminate redundant tests.

The is_function2 instruction is executed surprisingly
frequently when running dialyzer or the compiler. It
cannot hurt to optimize it a little.

When the schedulers never go to sleep (and thus never polls)
it may be that the fds in schedulers poll-sets are never polled.
Before this commit, this was solved by starting a timer when an
overload was detected. This had issues as overloads were not always
detected in time. So this commit reverts to the pre OTP-21 behaviour
so keep a global counter makes that the poll is called when it should.
