2019-03-28kernel: Fix performance regression on reading compressed filesJohn Högberg
An internal buffer size was too small, causing a considerable performance degradation compared to OTP 20.

2019-03-08[logger] Add option file_check to logger_std_hSiri Hansen
OTP-15663 This option indicates how often the handler shall check if the log file still exists and if the inode is changed.
2019-03-08[logger] Add log file rotation by options to logger_std_hSiri Hansen
OTP-15479 OTP-15662 New configuration map for logger_std_h: #{type => file, file => file:filename(), modes => [file:mode()], max_no_bytes => pos_integer() | infinity, max_no_files => non_neg_integer(), compress_on_rotate => boolean()} For backwards compatibility, the old variant for specifying the file name via the 'type' parameter is still supported, i.e. {file,FileName} and {file,FileName,Modes}, but it is no longer documented. Rotation scheme: The current log file always has the same name, and the archived files get extensions ".0", ".1", ... The newest archive has extension ".0", and the oldest archive has the highest number. If 'compress_on_rotate' is set to true, the archived files are gzipped and get the additional extension ".gz", e.g. error.log.0.gz. Rotation is turned off by setting 'max_no_bytes' to infinity. Setting 'max_no_files' to 0 does not turn off rotation, but only specifies that no archives are to be saved.

2019-03-06[logger] Add better control of file modes in logger_std_hSiri Hansen
OTP-15602 It is allowed to set file modes for the handler to use when opening its log file. The given modes were earlier accepted without any checks, which could make the handler behave unexpectedly. This commit makes sure that * if none of write, append or exclusive is given, then append is added * if raw is not given, it is added * if delayed_write or {delayed_write,_,_} is not given, then delayed_write is added

Adhering to the review in GitHub PR #2066: The start time should be set so the resolver file can get re-read as soon as possible to not get the whole timeout time before detecting that the resolver file has been created.

Add application:set_env/1 and application:set_env/2 OTP-15642
2019-03-01Add application:set_env/1 and application:set_env/2José Valim
It is equivalent to calling application:set_env/4 on each application individually, except it is more efficient. When given duplicate apps or duplicate keys, set_env/1 and set_env/2 will warn. The warning will also be emitted during boot: $ erl -config dupkeys.config -s erlang halt 2019-02-27 11:16:02.653100 application: kernel; duplicate parameter: key1 =WARNING REPORT==== 27-Feb-2019::11:16:02.653100 === application: kernel; duplicate parameter: key1 $ erl -config dupapps.config -s erlang halt 2019-02-27 11:16:02.653100 duplicate application config: kernel =WARNING REPORT==== 27-Feb-2019::11:16:02.653100 === duplicate application config: kernel Prior to this patch, the behaviour was unspecified, and duplicate keys and duplicate apps would behave different depending on the amount of config, the name of the config files, and how those configs would be listed. The goal is to raise an error in the future.

This is to align the timestamps with external logs.
2019-02-21[logger] Make sure log file is re-opened with configured file optionsSiri Hansen
Earlier, if the log file had to be re-opened, e.g. due to it being renamed or removed, it would always be opened with the default file options, even if other options were set in the configuration. Now, the configured options are used, except that 'append' is always added and 'exclusive' is always removed.

If the inode changes, the file is now reopened. This may happen, for instance, if the log file is opened and saved by an editor.

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.
