OTP-15663
This option indicates how often the handler shall check if the log
file still exists and if the inode is changed.

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.

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

[logger] Change timestamp from erlang:system_time to os:system_time

Add application:set_env/1 and application:set_env/2
OTP-15642
|
|
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.

Forward set/update indicator to handler callback changing_config
OTP-15364

* igor/tcp-nopush-ERL-698/OTP-15357:
"cork" tcp socket around file:sendfile
Add nopush TCP socket option
|
|
RaimoNiskanen/raimo/getifaddrs-netns/ERIERL-189/OTP-15121
Implement {netns,NS} option for inet:getifaddrs/1 and friends
|
|
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.

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.
|
|
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.
|
|
This function is similar to set_handler_config/3, but calls the handler
callback changing_config/3 with the first parameter SetOrUpdate=update.
|
|
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().

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.

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.

The encoding option was introduced in commit
270d909696a753af022df72a404c73f2895b4a02, to allow report callbacks to
format according to a given encoding. There was, however, no
connection between this encoding option, and the encoding of the
device to which the logger handler was writing.
Since a formatter is defined to return unicode:chardata(), and in
order to avoid mismatch with the encoding of the device, the encoding
option is now removed from the formatter. The handler itself must make
sure that it does not write illegal data to its device.
