2016-02-25kernel: Clarify heart optionBjörn-Egil Dahlberg
Change scheduler responsiveness to 'check_schedulers'.
2016-02-23kernel: Add builtin scheduler check for heartBjörn-Egil Dahlberg
In addition, the heart API is extended with the following functions: * heart:set_options/1 * heart:get_options/0 If heart:set_options([scheduler]) is set, heart will check scheduler responsiveness before every heartbeat to the heart port.

2016-02-16kernel: Add basic system check of schedulers on heartbeatBjörn-Egil Dahlberg
Before a heartbeat to the port program a responsiveness check of the schedulers is performed. If the responsiveness check fails, stalls, the heartbeat will not be performed (as intended).
2016-02-16kernel: Add validation callback for heartBjörn-Egil Dahlberg
* heart:set_callback/2 * heart:get_callback/0 * heart:clear_callback/0 The callback is called before every heartbeat to the heart port. The callback needs to return 'ok' if the validation is correct.

2016-01-28code: Correct the types for error returnsBjörn Gustavsson
The specifications for functions that load code in the 'code' module (e.g. code:load_file/1) have some problems: * The specs claim that the functions can return {error,on_load}, but they never do. However, they can return {error,on_load_failure} if the -on_load function in a module fails. * The specs claim that the functions can return {error,native_code}, but they never do. While we are it, also extend the on_load_errors/1 test case to test that the load functions return {error,on_load_failure} when an -on_load function fails.
2016-01-25Eliminate run-time system crash in code:load_abs/1Björn Gustavsson
The run-time system would terminate if code:load_abs/1 was called with a filename containing any non-latin1 characters. The reason is that code_server would attempt to construct a module name from the filename using list_to_atom/1 and that atoms currently are limited to the latin1 character set. But how should the error be reported? I have decided to that the simplest and least confusing way is to move the call to list_to_atom/1 to 'code' module and let it crash the calling process. The resulting stack back trace will make it clear what the reason for the crash was.

New timestamp options for trace, sequential trace, and system profile: - monotonic_timestamp - strict_monotonic_timestamp

2015-10-05Avoid always updating inet_dns in the primary bootstrapBjörn Gustavsson
The include file inet_dns_record_adts.hrl is generated by the Perl script inet_dns_record_adts.pl in a non-deterministic way. That is, every time the script is run, the functions will be in a different order. That will cause inet_dns.beam in the primary bootstrap to be updated every time the bootstrap is updated, even though there is no actual code change. Modify the Perl script to sort the keys pulled out from hashes to make the order deterministic.

2015-06-09Add 'show_econnreset' TCP socket optionRory Byrne
An ECONNRESET is a socket error which tells us that a TCP peer has sent an RST. The RST indicates that they have aborted the connection and that the payload we have received should not be considered complete. Up until now, the implementation of TCP in inet_drv.c has hidden the receipt of the RST from the user, treating it as though it was just a FIN terminating the read side of the socket. There are many cases where user code needs to be able to distinguish between a socket that was closed normally and one that was aborted. Setting the option {show_econnreset, true} enables the user to receive ECONNRESET errors on both active and passive sockets. A connected socket returned from gen_tcp:accept/1 will inherit the show_econnreset setting of the listening socket. By default this option is set to {show_econnreset, false}. Note that this patch only enables the reporting of ECONNRESET when the socket is being read from. It does not report ECONNRESET (or EPIPE) when the user tries to write to a connection when an RST has already been received. Currently the TCP implementation in inet_drv.c hides all such send errors from the user in favour of returning {error, close}. A separate patch will be needed to enable the reporting of such errors.

2015-06-04Move architecture knowledge out of hipe loaderRichard Carlsson
Make code_server be responsible for finding the architecture and deciding whether to try to load native code, in order to avoid repeated calls to system_info(hipe_architecture) and clumsy uses of try/catch to test if hipe is enabled.

2015-05-22Fix parsing of IPv6 addresses to limit leading zerosRory Byrne
The current implementations of inet:parse_ipv6_address/1 and inet:parse_ipv6strict_address/1 permit address strings which have an unlimited number of leading zeros. Addresses such as: "0000000000000000000000000000000ffff::" "::00000000000000000000000000000000000000000000000000000000" "::0000000f435:1" If we are using this facility to validate string representations of IPv6 addresses, then we would end up validating addresses which are non-conformant (with respect to RFC 4291 section 2.2) and potentially dangerous. This patch ensures that each segment of an IPv6 address has a maximum of 4 hex digits.
