Fix deadlock on panics at Entry.log 
When calling Entry.log a panic inside some of the
locking blocks could cause the whole logger to deadlock.

One of the ways this could happen is for a hook to cause
a panic, when this happens the lock is never unlocked and
the library deadlocks, causing the code that is calling
it to deadlock as well.

This changes how locking happens with unlocks at defer
blocks so even if a panic happens somewhere along the log
call the library will still unlock and continue to function.

DmitriyMV 3bcb09397d This commit fixes data race using atomics. We switch type of level from uint8 to uint32 but due memory alignment on most platforms it will not result in any additional memory. 2017-03-23 19:13:49 +03:00

Aaron Greenlee a7755c5c03 Enhanced fatal calls so exit handlers can be invoked 
While GO offers the ability to recover from panic there is no way to intercept an os.Exit event. To allow graceful shutdown and clean-up or programs which use Logrus to Fatal out I've borrowed ideas from the `atexit` package and enhanced Logrus.

Usage:
* When setting up the logger one call `RegisterExitHandler( func() {...} )` to add a handler that will be invoked for any `Fatal` call to the logger.

Shuhao Wu 511792f912 Added support to chain withfields 
`WithField` and `WithFields` right now doesn't chain properly. Meaning
that if you do something like:

    localLog := logger.WithField("tag", "value")
    localLog.WithField("v1", "value").Info("message1")
    localLog.Info("message2")

The `v1` will be carried over to `message2`.

With this patch, each WithField/WithFields call are isolated.

Anthony Bishopric 9f6da0e77c Defer formatting of log values in Levelf(), Levelln() 
The Level() family of log methods defer formatting of log
values until it is confident that the log level needs them.
This change allows that deferral to happen at the Levelf()
and Levelln() levels too.

This commit also adds benchmarks to demonstrate the improved
performance of these functions
