2014-10-29erts: Fix bug in beam_rangesSverker Eriksson
Symptom: VM on OSX (darwin11.4.2) with +Meamin running sasl tests, crashing when init:reboot() does erlang:purge_module(installer). Problem: Off-by-one bug in beam_ranges:find_range, returning the wrong range if the 'end' of one module is the 'start' of the next. This is only possible if using sys_alloc (+Meamin) as our own allocators always put block headers between allocated payload data.

2014-10-28Use isfinite() instead of finite() when availableAnthony Ramine
OS X Mavericks builds result in a number of warnings about finite() being deprecated, like these: beam/erl_arith.c:451:7: warning: 'finite' is deprecated: first deprecated in OS X 10.9 [-Wdeprecated-declarations] ERTS_FP_ERROR(p, f1.fd, goto badarith); ^ sys/unix/erl_unix_sys.h:319:33: note: expanded from macro 'ERTS_FP_ERROR' ^ sys/unix/erl_unix_sys.h:244:51: note: expanded from macro '__ERTS_FP_ERROR' ^ /usr/include/math.h:718:12: note: 'finite' has been explicitly marked deprecated here extern int finite(double) __OSX_AVAILABLE_BUT_DEPRECATED(__MAC_10_0, __MAC_10_9, __IPHONE_NA, __IPHONE_NA); Add checks to use isfinite() instead of finite() where available. Verified on OS X Mavericks 10.9.5 and Ubuntu 12.04.

2014-10-21erts: Fix bug when hipe tailcalls trapping BIF that disables GCSverker Eriksson
Symptom: base64_SUITE:roundtrip crashes with hipe compiled stdlib. Problem: HIPE_WRAPPER_BIF_DISABLE_GC pushed a "trap frame", but the frame was only popped if the call was recursive. Solution: Only reserve "trap frame" if BIF call is recursive.
2014-10-21erts: Fix hipe bug when gc-disabling bif traps with gc enabledSverker Eriksson
The trap_frame got pushed twice, first by the wrapper then by hipe_push_beam_trap_frame as it was looking at F_DISABLE_GC.
2014-10-20Merge branch 'lukas/erts/non-blocking-shell'Lukas Larsson
* lukas/erts/non-blocking-shell: Fix io:columns/0 timeout when invoked via user kernel,ssh: Add synchronous user_drv protocol erts: Make writing to non-tty fds non-blocking erts: Make tty driver non-blocking
2014-10-16kernel,ssh: Add synchronous user_drv protocolLukas Larsson
Added a put_chars_sync to the protocol that can be used to talk to user_drv and made group use it. This is needed in order to guarantee that bytes has been pushed to the tty port when doing something like this: io:format("halting\n"),erlang:halt(0). Before this change the halting message could be lost in the message queue of the user_drv process, this is no longer possible. This commit also fixes ssh_cli as that plugs itself in as a user_drv process. OTP-12240
2014-10-16erts: Make writing to non-tty fds non-blockingLukas Larsson
If the fd_driver is given non-tty fds it will now use an async thread instead of doing a blocking write. An example of a non-tty fd is the fd used by stderr, but could be anything handed down to the driver.
2014-10-16erts: Make tty driver non-blockingLukas Larsson
Instead of using blocking call to fwrite, the tty driver now uses non-blocking calls to writev and queues any output data that cannot be written into the driver queue. Without this change an stdout write could block an entire scheduler if for some reason the pseudo tty on the other side does not consume the output of the Erlang shell. OTP-12239

2014-10-03erts: Fix bug when delayed deallocated carrier is reused by cpool_fetchSverker Eriksson
The delayed dealloc queue destroyes one word but cpool_fetch() is expected to return healthy carriers. So we restore that overwritten word with a little bit of hackish code.

2014-10-02Fix missing field initializer in ERL_NIF_INIT macroSteve Vinoski
In the ERL_NIF_INIT macro, add a missing static initializer for the new options field which was added to the ErlNifEntry struct for 17.3. This fix prevents compile-time errors in NIFs when the compiler is instructed to treat missing field initializers as errors.

2014-09-30erts: Fix race between port_set_data, port_get_data and port terminationSverker Eriksson
Always update prt->data with atomic xchg-op. Check for NULL data to detect racing port terminator. Use NULL, as THE_NON_VALUE can be a valid pointer on debug VM.
2014-09-30erts: Fix erlang:port_set_data/2 for non immediate dataSverker Eriksson
hsize field was not set leading to VM crash
