2018-10-15HiPE: Fix check for when ErLLVM is availableKostis Sagonas
The previous check whether ErLLVM could be enabled and/or tested simply checked whether a suitable version of the LLVM tool chain was present in the path. Obviously this is not enough: there should also be a check that we are running in an architecture on which the ErLLVM compiler has been ported. Fix the function that provides this functionality and also rename it in order to more appropriately describe what it does. In principle, this change introduces a backwards incompatibility as the function is one of those exported by the `hipe' module, but this function was not documented and the chances that it has been used somewhere else that the test suite are pretty low (if not zero).

2018-10-11erts: Fix UNC path handling on WindowsJohn Högberg
This is unlikely to be the last of the path problems seen after OTP 21, and I'm starting to regret my decision to unconditionally use long paths. The idea to hit all long-path problems all the time was good in theory as it makes such bugs far more visible, but there just aren't enough people who test pre-release versions on Windows, making this the world's slowest game of whack-a-mole.
2018-10-11Add nopush TCP socket optionIgor Slepchin
This translates to TCP_CORK on Linux and TCP_NOPUSH on BSD. In effect, this acts as super-Nagle: no partial TCP segments are sent out until this option is turned off. Once turned off, all accumulated unsent data is sent out immediately. The latter is *not* the case on OSX, hence the implementation ignores "nopush" on OSX to reduce confusion.
2018-10-08Do not allow an empty string as node nameRichard Carlsson
Passing -sname '' or -sname '@bar' to erl would result in an obscure error message "Protocol 'inet_tcp': register/listen error: epmd_close" because the check for valid names did not disallow the empty string.

2018-10-03[logger] Add handler callback filter_config/1Siri Hansen
This function is called when a logger API function for fetching handler configuration is called. The point is to allow the handler to remove internal data fields that it might have stored in the configuration database, before returning the handler configuration to the caller. An example of such internal data are the 'handler_pid' and 'mode_tab' fields that logger_std_h and logger_disk_log_h store in their configuration maps.
2018-10-03[logger] Start using handler callback changing_config/3 in built-in handlersSiri Hansen
The new parameter to this function, SetOrUpdate, indicates how unspecified configuration data fields shall be set. The rule is that if SetOrUpdate equals set, then default values shall be used, and if SetOrUpdate equals update, then existing configuration values shall be used. Consequently, these examples now apply to logger_std_h and logger_disk_log_h: set_handler_config(default, config, #{sync_mode_qlen => 20}) sets the value of sync_mode_qlen to 20, and resets all other (writable) fields in the config map to their default values. update_handler_config(default, config, #{sync_mode_qlen => 20}) sets the value of sync_mode_qlen to 20, and leaves all other fields in the config map unchanged.
2018-10-03[logger] Add update_handler_config/3Siri Hansen
This function is similar to set_handler_config/3, but calls the handler callback changing_config/3 with the first parameter SetOrUpdate=update.
2018-10-02Implement {netns,NS} option for inet:getifaddrs/1Raimo Niskanen
Also implement the same option for the legacy undocumented functions inet:getif/1,getiflist/1,ifget/2,ifset/2. The arity 1 functions had before this change got signatures that took a socket port that was used to do the needed syscall, so now the signature was extended to also take an option list with the only supported option {netns,Namespace}. The Socket argument variant remains unsupported. For inet:getifaddrs/1 the documentation file was changed to old style function name definition so be able to hide the Socket argument variant that is visible in the type spec. The arity 2 functions had got an option list as second argument. This list had to be partitioned into one list for the namespace option(s) and the other for the rest. The namespace option list was then fed to the already existing namespace support for socket opening, which places the socket in a namespace and hence made all these functions that in inet_drv.c used getsockopt() work without change. The functions that used getifaddrs() in inet_drv.c had to be changed in inet_drv.c to swap namespaces around the getifaddrs() syscall. This functionality was separated into a new function call_getifaddrs().

2018-09-20[logger] Add SetOrUpdate parameter to handler callback changing_configSiri Hansen
Since logger has now knowledge of the handler specific data ('config' field in the handler configuration map), it can not merge this data structure with default or old values upon configuration change. Instead, the handler callback changing_config must do this. Earlier, this callback did not reflect if the configuration change was initiated by a call to set_handler_config or update_handler_config, so the handler did not know if unspecified fields should get default values or the values from the existing configuration. To overcome this problem, the new parameter SetOrUpdate is added to this callback. If SetOrUpdate equals set, then default values should be used. If SetOrUpdate equals update, then existing configuration values should be used.
