* Reduced overhead costs
* API to profile particular segments of code:
+ start: starts profiling
+ stop: stops profiling
+ reset: resets the result of profiling
def prof = new Profiler()
prof.start()
// code to profile
prof.stop()
prof.report.prettyPrint()
* Changed the package structure:
from gprof.* to groovyx.gprof.*
* Changed the versioning scheme:
from $major.$minor.$maintenance to $major.$minor.$maintenance-groovy-$groovyVersion
* Bug fixes:
+ Methods which are added dynamically are not profiled
+ Hangs up until all of profiled threads (except for a profiler thread) die
Version 0.2.0 (2013-04-14)
--------------------------
* Support for multi-threaded applications
* Support for using Grape
* Added includeMethods and excludeMethods options that filter by the name of packages,
classes and methods:
It supports the following wildcards:
| * | zero or more characters |
| ? | exactly one character |
The following example profile only methods which are of "java.*" or "groovy.*"
package but are not constructors:
profile(
includeMethods: [ "java.*", "groovy.*" ],
excludeMethods: [ "*.ctor" ]) {
// code to be profiled
}
* Added includeThreads and excludeThreads options that filter by the name of threads:
It supports the following wildcards:
| * | zero or more characters |
| ? | exactly one character |
The following example profile only methods which are called in the "thread-*"
thread but not in "thread-2" or "thread-3":
profile(
includeThreads: [ "thread-*" ],
excludeThreads: [ "thread-2", "thread-3" ]) {
// code to be profiled
}
* Bug fixes:
+ GProf fails to profile a multi-threaded application
+ Contains the time of children if the depth is more than two
+ There are classes that are not profiled
