- Following the Rails guide which state that a logger needs to include
the `ActiveSupport::LoggerSilence` as well as
`ActiveSupport::LoggerThreadSafe` modules isn't enough and won't
work.
Here is a test cases with 3 tests that all fails
https://gist.github.com/Edouard-chin/4a72930c2b1eafbbd72a80c66f102010
The problems are the following:
1) The logger needs to call `after_initialize` in order to setup
some instance variables.
2) The silence doesn't actually work because the bare ruby Logger
`add` method checks for the instance variable `@logger`. We need to
override the `add` (like we used to in the ActiveSupport::Logger
class).
3) Calling `debug?` `info?` etc... doesn't work as the bare ruby
methods will check for the instance variable. Again we need to
override this methods (like we used to in the ActiveSupport::Logger
class)
The LoggerSilence won't work without LoggerThreadSafe, but the later
is not public API, the user shouldn't have to include it so I
modified to include it automatically.
Same for the `after_initialize` method. I find unuintitive to have
to call it directly. I modified to instance the variables when the
module get included.
- I found this weird that the LoggerSilence wasn't using the
`ActiveSupport` namespace (AFAIK all other classes have it).
This PR deprecate the use of `LoggerSilence` for
`ActiveSupport::LoggerSilence` instead.
Fix#23609
Commit 629efb6 introduced thread safety to logger silencing but it
didn't take into account the fact that the logger can be extended with
broadcasting to other logger.
This commit introduces local_level to broadcasting Module which enables
broadcasted loggers to be properly silenced.
- uses instance defined level if no custom local log level defined
- Keeps track of local log level per [ thread + object-instance ]
- prevents memory leakage by removing local level hash key/value on #silence method exit
- avoids the use of Thread local variables
When setting the Rails logger to log to STDOUT, it would broadcast the
log twice in development. This adds a setting that will prevent messages
from being broadcast to multiple logs, while still allowing calls to
`#close`, `#level=`, `#progname=`, and `#formatter=` to be broadcasted.
Fixes#14769, #11415
