# 1.2.0
This new release introduces:
* A new method `SetReportCaller` in the `Logger` to enable the file, line and calling function from which the trace has been issued
* A new trace level named `Trace` whose level is below `Debug`
* A configurable exit function to be called upon a Fatal trace
* The `Level` object now implements `encoding.TextUnmarshaler` interface
# 1.1.1
This is a bug fix release.
* fix the build break on Solaris

To ensure this behaviour even if a TTY is attached, set your formatter as follows:
```go
log.SetFormatter(&log.TextFormatter{
DisableColors: true,
FullTimestamp: true,
})
```
#### Logging Method Name
If you wish to add the calling method as a field, instruct the logger via:
```go
log.SetReportCaller(true)
```
This adds the caller as 'method' like so:
```json
{"animal":"penguin","level":"fatal","method":"github.com/sirupsen/arcticcreatures.migrate","msg":"a penguin swims by",
"time":"2014-03-10 19:57:38.562543129 -0400 EDT"}
```
```text
time="2015-03-26T01:27:38-04:00" level=fatal method=github.com/sirupsen/arcticcreatures.migrate msg="a penguin swims by" animal=penguin
```
Note that this does add measurable overhead - the cost will depend on the version of Go, but is
between 20 and 40% in recent tests with 1.6 and 1.7. You can validate this in your
environment via benchmarks:
```
go test -bench=.*CallerTracing
```

This program reads a file containing function prototypes
(like syscall_darwin.go) and generates system call bodies.
The prototypes are marked by lines beginning with "//sys"
and read like func declarations if //sys is replaced by func, but:
* The parameter lists must give a name for each argument.
This includes return parameters.
* The parameter lists must give a type for each argument:
the (x, y, z int) shorthand is not allowed.
* If the return parameter is an error number, it must be named errno.
A line beginning with //sysnb is like //sys, except that the
goroutine will not be suspended during the execution of the system
call. This must only be used for system calls which can never
block, as otherwise the system call could cause all goroutines to
hang.

This program will generate three files and handle both gc and gccgo implementation:
- zsyscall_aix_ppc64.go: the common part of each implementation (error handler, pointer creation)
- zsyscall_aix_ppc64_gc.go: gc part with //go_cgo_import_dynamic and a call to syscall6
- zsyscall_aix_ppc64_gccgo.go: gccgo part with C function and conversion to C type.
The generated code looks like this
zsyscall_aix_ppc64.go
func asyscall(...) (n int, err error) {
// Pointer Creation
r1, e1 := callasyscall(...)
// Type Conversion
// Error Handler
return
