* BcelTypeMunger.mungeMethodDelegate: only use 'synchronized' when necessaryAlexander Kriegisch2023-01-071-3/+25
| | | | | | | | | | | | | | | | | | | | | Relates to #198. Now, we create a delegate method body which basically looks as follows: public void methodOne() { if (this.ajc$instance$MyAspect$MyMixin == null) { synchronized(this) { if (this.ajc$instance$MyAspect$MyMixin == null) { this.ajc$instance$MyAspect$MyMixin = MyAspect.aspectOf().createImplementation(this); } } } this.ajc$instance$MyAspect$MyMixin.methodOne(); } The idea for the outer null check is from @aclement, see https://github.com/eclipse/org.aspectj/pull/205#issuecomment-1371556080.

* Fix #366085 concerning declared annotations with source retentionAlexander Kriegisch2022-12-211-2/+8
| | | | | | | | | | | | | | | See https://bugs.eclipse.org/bugs/show_bug.cgi?id=366085. See https://stackoverflow.com/q/74618269/1082681. The issue described in the Bugzilla issue is about 'declare @type', but similar issues also existed for 'declare @field', 'declare @method', 'declare @constructor'. This fix is rather superficial and leaves things to be desired, because it is rather hacky and simply ignores errors source retention annotation declarations during weaving. A better fix would drop the corresponding declarations while parsing and also issue compiler warnings in each case. Signed-off-by: Alexander Kriegisch <Alexander@Kriegisch.name>

* | Optimize class loading - make backward compatible with legacy behaviourAlexander Kriegisch2022-01-131-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now the defaults are: + org.aspectj.apache.bcel.useSingleRepositoryInstance (default: false) + org.aspectj.apache.bcel.useUnavailableClassesCache (default: false) + org.aspectj.apache.bcel.ignoreCacheClearRequests (default: false) I.e. the new caching optimisations are opt-in instead of opt-out as originally designed. This might change in the future, but for now without any additional tests and experience with the new feature let us be conservative and make the build green first. I also added a few more code review findings concerning backward compatibility, which was less than 100% even with all three flags deactivated.

* | Optimize class loadingStefan Starke2022-01-131-14/+39
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | In our project we found out that during the build up of the spring context the class loading takes a very long time. Root cause is the huge amount of file I/O during pointcut class loading. We are taking about ~250k file loads. With these changes we managed to cut down the starting time by around 50%. What we found out is that IMHO - the clear method of the ClassLoaderRepository is called far too often -> in our settings this resulted in not a single cache hit as the cache got cleared permanently. Therefore we de-actived the cache clear calls inside the ClassLoaderRepository. Secondly we changed the Java15AnnotationFinder in a way to not always create new objects for the ClassLoaderRepository but re-use one static instance. Otherwise we experienced >100k objects being created. Last but not least we introduced a cache for unavailable classes so that they do not have to be looked up using file I/O over and over again. The whole behavior is configurable via + org.aspectj.apache.bcel.useSingleRepositoryInstance (default: true) + org.aspectj.apache.bcel.useUnavailableClassesCache (default: true) + org.aspectj.apache.bcel.ignoreCacheClearRequests (default: true) Signed-off-by: Stefan Starke <stefan@starkeweb.org> Signed-off-by: Alexander Kriegisch <Alexander@Kriegisch.name>

| | | | | | | | | | Trailing whitespaces are useless. Most of code-styles forbids them. Most of editors always trim them on save. I propose to clean up project from trailing whitespaces in all java files at once.
* | Replace uses of StringBuffer with StringBuilder.Andrey Turbanov2021-11-2017-29/+29

* Replace use of ASM-renamed by original ASMAlexander Kriegisch2021-05-163-15/+18
| | | | | | | | | | | | This involves replacing references in weaver application code as well as a few tests. In order to make AspectJ weaver + tools contain a relocated ASM version, I added a Maven Shade relocation step after Maven Assembly created the uber JARs. Relocation works for both binaries and sources and also encompasses Class::forName calls like in class AsmDetector. Signed-off-by: Alexander Kriegisch <Alexander@Kriegisch.name>

| | | | | | | | | | | Keep only ASM 2.0 binary because it is still used in UnweavableTest which uses an old ASM API, e.g. with a ClassWriter constructor which no longer exists. Also add JarJar 1.3 library because it is needed by an Ant task in lib/asm/build.xml. Signed-off-by: Alexander Kriegisch <Alexander@Kriegisch.name>

| | | | | | | | | | | Reset counter, just in case this test runs multiple times in one JVM. This can happen e.g. due to "run all tests" in IntelliJ IDEA, which directly runs this test class and als WeaverModuleTests, both of which implement junit.framework.TestCase. In that case, during the second run the counter would start at a higher base count, making the 2nd test run fail. Signed-off-by: Alexander Kriegisch <Alexander@Kriegisch.name>

* | Redundant Collection.addAll() callLars Grefer2020-08-154-14/+7
| | | | | | | | | | | | Reports Collection.addAll() and Map.putAll() calls after instantiation of a collection using a constructor call without arguments. Such constructs can be replaced with a single call to a parametrized constructor which simplifies code. Also for some collections the replacement might be more performant. Signed-off-by: Lars Grefer <eclipse@larsgrefer.de>
* | Collection.toArray() call styleLars Grefer2020-08-154-4/+4
| | | | | | | | | | | | | | There are two styles to convert a collection to an array: either using a pre-sized array (like c.toArray(new String[c.size()])) or using an empty array (like c.toArray(new String[0]). In older Java versions using pre-sized array was recommended, as the reflection call which is necessary to create an array of proper size was quite slow. However since late updates of OpenJDK 6 this call was intrinsified, making the performance of the empty array version the same and sometimes even better, compared to the pre-sized version. Also passing pre-sized array is dangerous for a concurrent or synchronized collection as a data race is possible between the size and toArray call which may result in extra nulls at the end of the array, if the collection was concurrently shrunk during the operation.
