2019-04-17[socket] CMsg header decode on darwinMicael Karlberg
The cmsg header (decode) problems on darwin was because the CMSG_FIRSTHDR macro is "faulty" on old versions (of darwin). I *think* it should return a NULL-pointer if there are no cmsg headers (but it does not). So, instead of punishing all platforms with an explicit test (msg_controllen >= sizeof(struct cmsghdr)) we only do this on darwin.
2019-04-17[socket] Building term with terms from different env (again)Micael Karlberg
When building the (activate next) select message, used terms from different environments, which is not allowed. This was during cancel of one request, we tries to activate next, and then building the select message (with terms from different environments). Arg! Details... OTP-15496
2019-04-17[socket] Type maniaMicael Karlberg
Why can't we all just get along? Casting to shut the compiler up.
2019-04-17[socket] Debug fixesMicael Karlberg
When setting (otp) debug to true, some debug printouts could become "laaarge". Removed the data from those printout to avoid problems.
2019-04-17[socket] Building term with terms from different env (again)Micael Karlberg
When building the (recv) select message, used terms from different environments, which is not allowed. OTP-15496
2019-04-17[socket] Building term with terms from different envMicael Karlberg
When building the (accept) select message, used terms from different environments, which is not allowed. OTP-15496
2019-04-17[socket] Fixed acceptor environment leakMicael Karlberg
Did the free and assign new acceptor in the wrong order, thereby causing an (acceptor) environment leak. OTP-15496
2019-04-17[socket] Fixed various windows issuesMicael Karlberg
Building on windows broken again: * The 'inline' keywork needs som work on windows. * Function was outside of if-def. * Missing prototypes resulted in default prototypes. In this case, the actual problem was missing if-defs for win32 (that made functions exist on windows when they should not). Not sure why it compiled just fine on win32 but not win64 though.
2019-04-17[socket] Make use of the new select (read|write) functionsMicael Karlberg
Make use of the new select functions; enif_select_[read|write], for read and write select. These functions allows us to construct the select message ourseves: {'$socket', Socket, select, Ref} This is in preparations for when we introduce the 'nowait' (or something similar) value for the timeout argument (in accept, read and write funcions). It also solves (we hope) the term leakage problems (it was difficult to free the environment when there was only one/socket). OTP-15496
2019-04-17[socket|net] Make set|get options safe and type prefixMicael Karlberg
Firstly, make sure socket (and own) options manipulations are safe by adding a mutex that we take in the setopt and getopt functions. Secondly, change type prefix of various types from 'Socket' to 'ESock' (for instance; SocketDescriptor -> ESockDescriptor). OTP-15496
2019-04-17[socket] Restructure the close function(s)Micael Karlberg
To increase readability the close function has been slightly restructured.
2019-04-17[socket] Restructure the recvmsg result checkMicael Karlberg
To increase readability the recvmsg result check has been slightly restructured. In this case we made use of the error case function (fail) of the recv result check.
2019-04-17[socket] Restructure the recvfrom result checkMicael Karlberg
To increase readability the recvfrom result check has been slightly restructured. In this case we made use pf the error case function (fail) of the recv result check.

To increase readability the recv result check has been slightly restructured.
2019-04-17[socket] Restructure the send result checkMicael Karlberg
To increase readability the send result check has been slightly restructured.
2019-04-17[socket] Messages from the nif code now has a proper socketMicael Karlberg
The messages sent from the nif code to an erlang process has been changed to: {'$socket', Socket :: socket(), Tag :: atom(), Info :: term()} This is in preparation for (using) the new enif select API. OTP-15496
2019-04-17[esock] Fixed socket close raceMicael Karlberg
Used ref from wrong environment when building reply.

* john/erts/unc-path-size-fix/OTP-15693: erts: Fix incorrect UNC path length calculation
2019-03-22erts: Fix incorrect UNC path length calculationJohn Högberg
This didn't cause any issues for the most part since the path was still properly formed, but it broke down when appending the wildcards in file:list_dir/1. The ASSERT_PATH_FORMAT macro would have caught this in no time, but it went unnoticed because we don't run debug builds on Windows.

2019-03-19[socket] Another try at fixing the NULL envMicael Karlberg
During socket stop the close environment somehow has been NULLed. Check this before using when sending the close message.
2019-03-18[socket|net] Temporary fix for absence of clock_gettime(CLOCK_REALTIMEMicael Karlberg
We use clock_gettime(CLOCK_REALTIME, ...) to create a simple timestamp. This is used both for debugging and when writing error/warning messages (from the nif-code). The workaround for the absence of this function (on some platforms, old versions of darwin for example) is to simply skip the timestamp.

2019-03-18[socket] Fixed socket close issueMicael Karlberg
Fixed an issue (I think) that during socket close could cause a core.
2019-03-15[net] Fixed memory leak in address info encodingMicael Karlberg
Fixed a memory leak in the function for address infos encoding.
2019-03-15[socket] Fixing debug printoutMicael Karlberg
A debug printout in the socket_stop fucntion used the wrong requestor record for the pid, which may leasd to a confusing debug printout.
2019-03-14[socket] The activate-next always used read selectMicael Karlberg
The activate-next (reader|writer|acceptor) always *incorrectly* used the read select function. This has now been changed so that the functions are created via a macro with an argument specifying which select function to use.
2019-03-06[socket] More if-def to make it "work" on windowsMicael Karlberg
2019-03-06[socket] Use (new) enif_compare_pids functionMicael Karlberg
Replace the won function for pid compare with the (new) enif_compare_pids function. OTP-15565
2019-03-06[socket] CommentaryMicael Karlberg
Add some more comments in order to increase readability. OTP-15565
2019-03-06[socket] Macro abuse of activate-nextMicael Karlberg
Implemented the activate_next function and added its "users" acceptor, writer and reader (macro abuse). After a request (accept, write or send) has been either successfully completed or failed, another request should be activated. Previously only one attempt was made, which might leave the other (waiting) requestors hanging. Now, instead we use a 'activate-next' function that pop's the request (accept, wrote or read) queue until success or its empty, thereby making sure that no waiting processes is left hanging. OTP-15565
2019-03-05[socket] Make use of official monitor to term functionMicael Karlberg
Remove own function to make monitor printable (was a hack) and make use of the new enif_make_monitor_term instead.

2019-03-04[socket] Fixed various type size and unused function warningsMicael Karlberg
Fixed some type size warnings (SCTP related). E.g: On Solaris 11 (OpenIndiana Hipster) long and int is size 4, but the way Sint32 def works it first "tests" for long size and if that is correct, that is chosen (which it is on Solaris 11). On linux long is size 8, so Sint32 will be defined as int. ... On Solaris 11 the flags TCP_CONGESTION and SO_BINDTODEVICE does not exist, so the function(s) n[set|get]opt_str_opt is never used. So, in order to keep the compiler quiet, we add some if-def to exclude these functions in this case.
2019-03-04[socket] Some minor cleanup and commentsMicael Karlberg
2019-03-04[socket] Macro abuse for requestor queue func defMicael Karlberg
The requestor (acceptor, writer and reader) functions are virtually identical, so to ensure quality and not having to write the exact same functions three times, we make use of some macro magic for their declaration. OTP-15565
2019-03-04[net] Macro abuse for func defMicael Karlberg
Some more macro abuse for nif API callback functions. OTP-15565
2019-03-04[socket] Macro abuse for more func defMicael Karlberg
Some more macro abuse for nif API callback functions and the operator (acceptor, writer and reader) queue wrapper functions (search4pid, push, pop and unqueue). OTP-15565
2019-03-04[socket] Macro abuse for setopt(otp) and getopt(otp)Micael Karlberg
2019-03-04[socket|net] Macro abuseMicael Karlberg

2019-03-01[net] Fixed getnameinfo functionMicael Karlberg
The getnameinfo function has been fixed: 1) Faulty sockaddr decode success check 2) Incorrect (name info) return value OTP-15636
2019-02-22[socket] Cleanup and accept restructureMicael Karlberg
Some cleanup (of open, bind, connect) and rewrote the accept code (moved the code into smaller functions). OTP-14831
2019-02-22[socket] More fixes to socket closeMicael Karlberg
Better handling of socket close. The 'closeRef' needed its own environment to make if work in both cases (both called and scheduled). Also Introduced the enif select wrapper functions (read, write, stop and cancel). Also add error handling at every time one of these functions are called. OTP-14831
2019-02-22[socket] Fixed socket close bugMicael Karlberg
Fixed a raise condition bug in the socket_stop (callback) function that could result in the socket actually *not* beeing closed. OTP-14831
2019-02-22[socket-nif] Fix buggy use of NULL-monitorSverker Eriksson
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).
