'raimo/kernel/inet_ntoa_1-IPv6-lowercase/ERIERL-20/ERL-429/OTP-13006' * raimo/kernel/inet_ntoa_1-IPv6-lowercase/ERIERL-20/ERL-429/OTP-13006: Accept IPv6 address %suffixes when parsing Adjust inet:ntoa/1 to RFC5952, but not deeper Update inet:ntoa according to modern RFCs
2017-06-12Accept IPv6 address %suffixes when parsingRaimo Niskanen
This only implements decimal suffixes, and furthermore only with a leading "0". A complete implementation would probably allow one and probably two digit suffixes without. But what primarily is missing is translating interface names to and from interface indexes. This also only implements the parsing, and uses the FreeBSD trick of squeezing in the Scope Id in the second 16-bit word of the fe80::/64 or ff02:/64 address prefix. But inet_drv is not prepared to handle this word, so it might only work on FreeBSD, not being supported even there... So inet_drv needs to handle this too.
2017-06-07Adjust inet:ntoa/1 to RFC5952, but not deeperRaimo Niskanen
There are a multitude of RFC:s that point to each other and some of them suggest different addresses with IPv4 suffixes. Use the IPv4 suffix text representation only for the old well known ::a.b.c.d and ::ffff:a.b.c.d prefixes. The others seems to be moving targets.

* lukas/erts/sendfile_sunos_fix/OTP-14424: erts: Fix sendfile closeduring scenario on sunos
2017-06-07erts: Fix sendfile closeduring scenario on sunosLukas Larsson
On Solaris, giving a too long sfv_len results in an EINVAL error, but data is still transmitted and len is correctly. So we translate this to a success with that amount of data sent. This may hide some other errors that causes EINVAL, but it is the best we can do for now.

2017-05-24kernel: Make sure to cleanup after distr testsLukas Larsson
Because this test suite did not cleanup after itself, the error_logger_warn_SUITE:file_utc failed to start its node that it needed for the test.

* lukas/kernel/ipv6_skip_tc_fixes: kernel: Skip ipv6 tcs when cpiv6 is disabled
2017-05-22kernel: Skip ipv6 tcs when cpiv6 is disabledLukas Larsson
For some reason doing a gen_udp:open(0, [inet6,{ipv6_v6only,true}]) works on some systems where ipv6 is disabled. So instead we explicitly require the localhost ip to do the test at which seems to work better. ipv6 was disabled in sysctl using the line net.ipv6.conf.all.disable_ipv6=1 when this behaviour was found.

2017-05-17add option 'quiet' to disk_logFred Hebert
This option allows to suppress output of info_msgs to error_logger when recoverable errors are encountered in disk_log by setting the value to 'true'. Defaults to 'false', the backwards compatible behaviour.

Running this test when for some reason stdlib has been unstickied could cause the emulator to die. So we check first to make sure that the expected files are sticky.

* maint: Store messages for 'rex' and 'error_logger' off heap file: match enoent and enotdir in path_open
2017-02-03Store messages for 'rex' and 'error_logger' off heapBjörn Gustavsson
Performance for processes that receive huge amounts of messages can be increased by storing the incoming messages outside the heap (that avoids copying the message in a garbage collection). Two OTP processes that are known to receive many messages are 'rex' (used by 'rpc') and 'error_logger'.
2017-01-30Add new AtU8 beam chunkJosé Valim
The new chunk stores atoms encoded in UTF-8. beam_lib has also been modified to handle the new 'utf8_atoms' attribute while the 'atoms' attribute may be a missing chunk from now on. The binary_to_atom/2 BIF can now encode any utf8 binary with up to 255 characters. The list_to_atom/1 BIF can now accept codepoints higher than 255 with up to 255 characters (thanks to Björn Gustavsson).

2016-11-29Improve caching in disk_logRichard Carlsson
Avoid starting timers for flushing when the written data is empty or larger than the max cache size. Previously, a single huge write to an empty cache would be put in the cache until the next write or the timer event. Also increase the cache size from 16K to 64K.
