2019-01-16[logger] Remove info and reset functions from handler modulesSiri Hansen
These are not documented, and only used in test. The test now uses logger_olp directly instead.

This is to ensure that logger_proxy gets the same config after a restart.

2018-12-13erts: Fix seq_trace:reset_trace dirty gc bugLukas Larsson
When seq_trace:reset_trace could be called while a process was doing a dirty GC. This triggered a race where all signals was moved to the internal signal queue during the GC which in turn caused the a heap overrun problem. This fix makes it so that the main and msgq lock are taken before the clear. This will make sure that we are allowed to do the clear.

This avoids an unexpected EXIT message with reason normal beeing printed from logger_server when the simple handler is replaced. It will still be printed if it exists unexpectedly.

2018-10-19[logger] Write asynchronously to disk logSiri Hansen
This commit updates logger_disk_log_h to write most log events asynchronlously (disk_log:balog/2), but synchronously (disk_log:blog/2) on every 20th event in the same way as logger_std_h does. This is for efficiency reasons.

There was a lot of duplicated code in logger_std_h and logger_disk_log_h. Most of this is now moved to logger_h_common, which now also serves as the gen_server callback.

RaimoNiskanen/raimo/getifaddrs-netns/ERIERL-189/OTP-15121 Implement {netns,NS} option for inet:getifaddrs/1 and friends
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.
2018-10-03[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().
2018-09-27Update kernel, stdlib and sasl appups for OTP-21.2Siri Hansen
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.

2018-09-14[logger] Read config before terminating handler processSiri Hansen
When a handler process is terminated due to overload, it reads its configuration from the configuration database, so it can be restarted with the same configuration after a small delay. This was earlier done in a different process, which was spawned off from the terminate function. This caused a race condition, where in some cases, the configuration was already removed before it could be read. The reason for spawning off a process, is to avoid a deadlock due to the call to logger:remove_handler/1. This commit moves the call to logger:get_handler_config/1 back to the handler process - to ensure that the data is still there, but keeps the call to logger:remove_handler/1 in the spawned off process - to avoid deadlock.
2018-09-12[error_logger] Handle report_cb with arity 2Siri Hansen
2018-09-12[logger] Include single_line option to report_cbSiri Hansen
If the report callback function has two arguments, the second argument is a map with options to limit the size of the log event. To even allow a better formatting when the event shall be printed on a single line, the new option single_line is now included in this argument.
2018-09-12[logger] Check for deadlock when removing filtersSiri Hansen
If a filter fails, it is removed by a call to logger:remove_filter/1,2. If the log event that caused the failure was issued on the logger process itself, this would earlier cause a deadlock due to a gen_server:call to self(). This is now prevented.
