* raimo/type-posix-0-overhaul/ERL_550/OTP-14019: Update types for posix error codes
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

2018-03-24Avoid overflowing the atom tableBjörn Gustavsson
Use integer variable names instead of atoms in v3_core, sys_core_fold, and v3_kernel to avoid overflowing the atom table. It is a deliberate design decision to calculate the first free integer variable name (in sys_core_fold and v3_kernel) instead of somehow passing it from one pass to another. I don't want that kind of dependency between compiler passes. Also note that the next free variable name is not easily available after running the inliner.

2018-03-23cerl_inline: Fix a name capture bugBjörn Gustavsson
The way variables created by make_template() are used, it is necessary that the names are unique in the entire function. This has not happened to cause any problems in the past because all other compiler passes created atom variable names, not integer variable names. If other passes start to create integer variable names, this bug is exposed.
2018-03-23Allow the match context identifier to be any termBjörn Gustavsson
During compilation, the bs_save2 and bs_restore2 instructions contain a match context reference. That reference is the variable name that holds the match context. beam_clean assumes that the reference always is an atom, which is not a safe assumption since integers are legal variable names in Core Erlang.

Implementation of true asynchronous signaling between processes
2018-03-21Implementation of true asynchronous signaling between processesRickard Green
Communication between Erlang processes has conceptually always been performed through asynchronous signaling. The runtime system implementation has however previously preformed most operation synchronously. In a system with only one true thread of execution, this is not problematic (often the opposite). In a system with multiple threads of execution (as current runtime system implementation with SMP support) it becomes problematic. This since it often involves locking of structures when updating them which in turn cause resource contention. Utilizing true asynchronous communication often avoids these resource contention issues. The case that triggered this change was contention on the link lock due to frequent updates of the monitor trees during communication with a frequently used server. The signal order delivery guarantees of the language makes it hard to change the implementation of only some signals to use true asynchronous signaling. Therefore the implementations of (almost) all signals have been changed. Currently the following signals have been implemented as true asynchronous signals: - Message signals - Exit signals - Monitor signals - Demonitor signals - Monitor triggered signals (DOWN, CHANGE, etc) - Link signals - Unlink signals - Group leader signals All of the above already defined as asynchronous signals in the language. The implementation of messages signals was quite asynchronous to begin with, but had quite strict delivery constraints due to the ordering guarantees of signals between a pair of processes. The previously used message queue partitioned into two halves has been replaced by a more general signal queue partitioned into three parts that service all kinds of signals. More details regarding the signal queue can be found in comments in the erl_proc_sig_queue.h file. The monitor and link implementations have also been completely replaced in order to fit the new asynchronous signaling implementation as good as possible. More details regarding the new monitor and link implementations can be found in the erl_monitor_link.h file.
