2015-10-22erts: Detect and build on MSYS2 for windowsDan Gudmundsson
Allow building win32 on MSYS2. Avoid msys2 path conversion which does not work. And print the real windows command when something fails.

If the process stack contained a match state the print function would crash the vm as it was not recognized by tag_val_def(). Add new MATCHSTATE_DEF returned by tag_val_def(). All other callers either ignore it or has a default clause to handle invalid terms.

* sverk/hipe-fix-literal-crc: erts,hipe,dialyzer: Fix hipe checkum of target runtime system erts: Change THE_NON_VALUE to not be hard coded in hipe compiler OTP-12962 OTP-12963 OTP-12964
2015-08-31erts,hipe,dialyzer: Fix hipe checkum of target runtime systemSverker Eriksson
Main problem: A faulty HIPE_LITERAL_CRC was not detected by the loader. Strangeness #1: Dialyzer should ask the hipe compiler about the target checksum, not an internal bif. Strangeness #2: The HIPE_SYSTEM_CRC checksum was based on the HIPE_LITERALS_CRC checksum. Solution: New HIPE_ERTS_CHECKSUM which is an bxor of the two (now independent) HIPE_LITERALS_CRC and HIPE_SYSTEM_CRC. HIPE_LITERALS_CRC represents values that are assumed to stay constant for different VM configurations of the same arch, and are therefor hard coded into the hipe compiler. HIPE_SYSTEM_CRC represents values that may differ between VM variants. By default the hipe compiler asks the running VM for this checksum, in order to create beam files for the same running VM. The hipe compiler can be configured (with "make XCOMP=yes ...") to create beam files for another VM variant, in which case HIPE_SYSTEM_CRC is also hard coded. ToDo: Treat all erts properties the same. Either ask the running VM or hard coded into hipe (if XCOMP=yes). This will simplify and reduce the risk of dangerous mismatches. One concern might be the added overhead from more frequent calls to hipe_bifs:get_rts_param.

Add forgotten HIPE_WRAPPER_BIF_DISABLE_GC which could lead to stack-heap overrun if unlucky with the yielding during maps:merge when called by native hipe code.

2015-08-27Fix ethread events with timeoutRickard Green
Lots of pthread platforms unnecessarily falled back on the pipe/select solution. This since we tried to use the same monotonic clock source for pthread_cond_timedwait() as used by OS monotonic time. This has been fixed on most platforms by using another clock source. Darwin can however not use pthread_cond_timedwait() with monotonic clock source and has to use the pipe/select solution. On darwin we now use select with _DARWIN_UNLIMITED_SELECT in order to be able to handle a large amount of file descriptors.
2015-08-24erts: Change THE_NON_VALUE to not be hard coded in hipe compilerSverker Eriksson
Instead ask running VM for the value of THE_NON_VALUE, which is different between opt and debug VM. Same hipe compiler can now compile for both opt and debug VM.
2015-08-21Improve choice of clock sources at build timeRickard Green
- Documented the configure switch --with-clock-resolution=<RES> - Changed default clock source for OS system time on Darwin to gettimeofday(). In order to use clock_get_time(CALENDER_CLOCK, ...) on Darwin, the user has to pass --with-clock-resolution=high when configuring the build.

* vinoski/stderr-eagain/OTP-12942: Handle ERRNO_BLOCK in fd_driver async functions
2015-08-18Handle ERRNO_BLOCK in fd_driver async functionsSteve Vinoski
Several users on erlang-questions have reported problems with recent releases where output to standard_error causes standard_error_sup to die from receiving an unexpected eagain error. In the fd_driver, change the fd_async() function to handle EINTR, and change fd_ready_async() to handle ERRNO_BLOCK. Add a new test to standard_error_SUITE to generate output to standard_error and ensure that standard_error_sup does not die. Thanks to Kota Uenishi for contributing the test case.

2015-08-10Teach smp VM how to deal with crash of a linked trace portSverker Eriksson
Problem: The sys-msg-dispather crashes the VM when trying to send exit signals from the links of the terminating trace port. If try-lock of the linked process fails, a pending exit is scheduled and erts_scheduler_data() is then called to find "my" run queue. But sys-msg-dispatcher is not a scheduler and has no scheduler data, hence SEGV. Fix: If not a scheduler and we cannot get process locks, schedule process in its previous run-queue.

2015-07-31erts: fix binary_to_integer boundary caseMikael Pettersson
erlang:binary_to_integer/1 and /2 fail to detect invalid input consisting of a single + or - sign but nothing else. For an input like <<"+">> they return 0, while list_to_integer/1 correctly signals a badarg for "+". Fixed by checking if the input is empty after the initial +/- sign processing. Added a test case which fails without this fix but passes with it. Thanks to "niku" for reporting the issue.

2015-07-08Fix crash when disassembling modules with BIFsBjörn Gustavsson
In a debug-compiled emulator, running erts_debug:df(io) would trigger an assertion failure: 1> erts_debug:df(io). beam/beam_debug.c:301:erts_debug_disassemble_1() Assertion failed: (((funcinfo[0]) & 0x3F) == ((0x0 << 4) | ((0x2 << 2) | 0x3))) Aborted (core dumped) It turns out that the assertion is wrong. It should have been updated in 64ccd8c9b7a7 which made it possible to have stubs for BIFs in the BEAM code for a module. The faulty assertion was only found when when 16317f73f79265 added a smoke test of the BEAM disassembler.
