2018-04-19Make stacktraces consistent when backtrace_depth is 0Björn Gustavsson
It is allowed to set the backtrace depth to 0, but when an exception is catched the stacktrace will still contain one element: 1> erlang:system_flag(backtrace_depth, 0). 8 2> catch error(badarg). {'EXIT',{badarg,[{shell,apply_fun,3, [{file,"shell.erl"},{line,908}]}]}} However, when an exception is raised using `erlang:raise/3`, there will be no elements in the stacktrace: 3> catch erlang:raise(error, badarg, [{fake,name,[arg],[]}]). {'EXIT',{badarg,[]}} Since the `error_handler` module uses `erlang:raise/3` to raise an exception when an undefined function is called, there will not be any stacktrace when calling an undefined function: 4> catch undef_module:undef_name(some_argument). {'EXIT',{undef,[]}} Fix this inconsistency by changing `erlang:raise/3` so that it always includes one element in the stacktrace: 3> catch erlang:raise(error, badarg, [{fake,name,[arg],[]}]). {'EXIT',{badarg,[{fake,name,[arg],[]}]}} 4> catch undef_module:undef_name(some_argument). {'EXIT',{undef,[{undef_module,undef_name,[some_argument],[]}]}}

2018-04-05Support dumping of external fun literals to a crash dumpBjörn Gustavsson
63e1c58d27ab (PR #1725) started to compile external funs as literals. This commit updates the dumping of literal areas to dump external fun literals to the crash dump.

Currently (OpenBSD 6.2) the kqueu implementation on opnebsd does not work properly for EOF conditions when using EV_DISPATCH, so we use the EV_ONESHOT fallback there.

2018-03-26Compile external fun expressions to literalsMichał Muskała
The expressions fun M:F/A, when all elements are literals are also treated as a literal. Since they have consistent representation and don't depend on the code currently loaded in the VM, this is safe. This can provide significant performance improvements in code using such functions extensively - a full function call to erlang:make_fun/3 is replaced by a single move instruction and no register shuffling or saving registers to stack is necessary. Additionally, compound data types that contain such external functions as elements can be treated as literals too. The commit also changes the representation of external funs to be a valid Erlang syntax and adds support for literal external funs to core Erlang.

* raimo/type-posix-0-overhaul/ERL_550/OTP-14019: Update types for posix error codes
2018-03-26Add +sbwt/+swt analogues for dirty schedulersJohn Högberg
Sharing these settings for all schedulers can degrade performance, so it makes sense to be able to configure them separately. This also changes the default busy-wait time to "short" for both kinds of dirty schedulers.
2018-03-26Update types for posix error codesRaimo Niskanen
I have read the man pages for most socket and file operations on recent Linux, FreeBSD, OpenBSD and Solaris 10 and noted the possible error codes. Which error codes that are possible for file operations have been updated in file:posix/0. Error codes for socket operations in inet:posix/0. The latter refers to the former so it is a superset, assuming that e.g sendfile and AF_UNIX socket operations could cause socket operations to return any file error code. That is not entirely true, but could be, especially in the future. Added to file:posix/0 are: ebadmsg edeadlk edeadlock eftype emultihop enobufs enolck enolink enosr enostr enosys eopnotsupp eoverflow erange etxtbsy Added to inet:posix/0 are all but: exbadport exbadseq file:posix() These are still possible according to erl_posix_str.c, but are not in file:posix/0 nor in inet:posix/0, and many of them are not file nor inet related, but some might be: e2big eadv ealign ebade ebadfd ebadr ebadrpc ebadrqc ebadslt ebfont echild echrng ecomm edirty edom edotdot eduppkg eidrm einit eisnam elbin el2hlt el2nsync el3hlt el3rst elibacc elibbad elibexec elibmax elibscn elnrng enavail enet enoano enocsi enodata enoexec enonet enosym enotempty enotnam enotuniq eproclim eprocunavail eprogmismatch eprogunavail erefused eremchg eremdev eremote eremoteio eremoterelease erpcmismatch erremote eshutdown esrmnt esuccesss etime etoomanyrefs euclean eunatch eusers eversion exfull sysnotready vernotsupported ediscon enomore ecancelled einvalidproctable einvalidprovider eproviderfailedinit syscallfailure service_not_found type_not_found e_no_more e_cancelled unknown
