Persistent terms are useful for storing Erlang terms that are never
or infrequently updated. They have the following advantages:
* Constant time access. A persistent term is not copied when it is
looked up. The constant factor is lower than for ETS, and no locks
are taken when looking up a term.
* Persistent terms are not copied in garbage collections.
* There is only ever one copy of a persistent term (until it is
deleted). That makes them useful for storing configuration data
that needs to be easily accessible by all processes.
Persistent terms have the following drawbacks:
* Updates are expensive. The hash table holding the keys for the
persistent terms are updated whenever a persistent term is added,
updated or deleted.
* Updating or deleting a persistent term triggers a "global GC", which
will schedule a heap scan of all processes to search the heap of all
processes for the deleted term. If a process still holds a reference
to the deleted term, the process will be garbage collected and the
term copied to the heap of the process. This global GC can make the
system less responsive for some time.
Three BIFs (implemented in C in the emulator) is the entire
interface to the persistent term functionality:
* put(Key, Value) to store a persistent term.
* get(Key) to look up a persistent term.
* erase(Key) to delete a persistent term.
There are also two additional BIFs to obtain information about
persistent terms:
* info() to return a map with information about persistent terms.
* get() to return a list of a {Key,Value} tuples for all persistent
terms. (The values are not copied.)

This is needed for testcases to run correctly.

I did not find any legitimate use of "can not", however skipped
changing e.g RFCs archived in the source tree.

Log events issued via error_logger:info_msg or
error_logger:info_report are now forwarded to Logger with level
'notice' instead of 'info'.
Log events issued by gen_* behaviours are also changed from level
'info' to level 'notice'.
Progress reports are still 'info', and can therefore easily be
included/excluded by changing the primary log level. By default, they
are not logged.
|
|
And add field 'module' in handler config.
|
|
Added:
* logger:get_config() - replaces i(), returns all Logger
configuration, i.e. primary and handler config, and module levels
* logger:get_handler_ids() -> [HandlerId]
* logger:get_handler_config() -> [{HandlerId,Module,Config}]
Removed:
* logger:i/1, will probably be replaced in a later release.

Also, change HandlerId from logger_simple to simple.

This configuration option has been removed. logger_formatter will read
the utc_log configuration parameter and format the timestamp
accordingly.

Most logger configuration that was possible through
kernel application variables have been moved into a
common 'logger' application environment in kernel.
Now all the configuration possible through the logger
API can be done as sys config.
The handler started by kernel has been renamed to 'default'
instead of logger_std_h.
There is a new logger:setup_handlers/1 function that given an
application name can be used to setup handlers in other applications.

It is now explicitly stated that if the application type is `load`, the
application will not actually be restarted by the `restart_application`
instruction in relup, even if it is currently running. It will only be stopped
and re-loaded.
