* 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>

| | | | | | | | | Before, we used 1.9.7.BUILD-SNAPSHOT, which according to Andy Clement was originally an intent across a group of Spring projects he was involved in, to ensure that SNAPSHOTS were sorted alphabetically ahead of MILESTONEs and ahead of RCs.

* Replace use of ASM-renamed by original ASMAlexander Kriegisch2021-05-164-17/+20
| | | | | | | | | | | | 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>
* Provision libraries in 'lib' automaticallyAlexander Kriegisch2021-05-051-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Upon special request by Andy Clement, I included 'lib' as a child module in the parent POM again, making several modules which refer to downloaded library files dependent the 'lib' module. I am not sure I caught all of them, but I hope so. Now after cloning the project and configuring the token for reading from GitHub Packages (sorry!), you can just run a Maven build for the main project and no longer need to fail the first build, read the Maven Enforcer message and run 'cd lib && mvn compile' as a first step. This convenience comes at the price of a more complex POM and two new profiles: - Profile 'provision-libs' is auto-activated by the absence of a marker file, kicking off the library provisioning process and creating same marker file at the end, if successful. Therefore, during subsequent builds libraries will not be re-provisioned, because the marker file exists and Maven skips all download and (un)zip steps, which saves build time and bandwidth. Otherwise offline builds would not work either. - Profile 'clean-libs' needs to be activated manually, because by default 'mvn clean' will not erase provisioned libraries. In most cases, even after a clean a developer does not want to re-provision all libraries if they have not changed (e.g. new JDT Core build). But if you do wish too erase the libraries and the marker file, just call 'cd lib && mvn -P clean-libs clean'. Please note: The Maven Enforcer build step, which additionally checks for existence of other files, still exists and was moved from the parent POM to 'libs'. No matter if provisioning was just done or skipped because the main marker file exists, a quick heuristic check for that list of files is done during each build, failing the build with a comprehensive message if an inconsistency was found. The error message says which files are missing and tells the user: "There is an inconsistency in module subdirectory 'lib'. Please run 'mvn --projects lib -P clean-libs clean compile'. This should take care of cleaning and freshly downloading all necessary libraries to that directory, where some tests expect them to be." This should cover the topic.

* Remove redundant 'name' and 'packaging' tags from POMsAlexander Kriegisch2021-04-151-2/+0

* Clean up Maven dependencies using 'dependency:analyze' goalAlexander Kriegisch2021-04-121-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Notably, this change involves a partial revert of @4a5660b3, because we are not using JUnit Jupiter yet but still JUnit 4 tests. See discussion under commit at https://github.com/eclipse/org.aspectj/commit/4a5660b3. Many other warnings - concerning both used undeclared and unused declared dependencies - were eliminated by adding or removing the corresponding dependencies from the POMs. Furthermore, I tried to make sure that some clearly test-scoped dependencies are now actually declared as such, so as to avoid unwanted transitivity bleeding into compile scope and maybe unwanted classes ending up in uber JARs via Maven Shade or Maven Assembly. TODO: I am not so sure why modules other than 'run-all-unit-tests' would depend on test JARs. I hope I broke nothing essential there. As of today, the other modules where I found '<type>test-jar</type>' dependencies are: - ajde - testing - testing-drivers - tests - weaver Signed-off-by: Alexander Kriegisch <Alexander@Kriegisch.name>
* Clean up remaining references to system-scoped dependenciesAlexander Kriegisch2021-04-101-9/+0

* Make sure to clean up temp-dirs in 'weaver' moduleAlexander Kriegisch2021-04-091-2/+5

* Module 'asm-renamed' now deploys to GitHub PackagesAlexander Kriegisch2021-04-091-5/+2
| | | | | | | | | | | This means that instead of a system-scoped dependency we now have a regular one. The 'libx' module also downloads binary and source JARs redundantly into the libraries directory in order to be found there by other scripts and tests.

* Replace system-scoped dependency on commons by granular dependenciesAlexander Kriegisch2021-03-291-0/+2
| | | | | | | | | | | | There are only two direct dependencies used in AspectJ code: - Commons Digester (module 'testing') - Commons Logging (module 'org.aspectj.matcher') I declared those two and experimentally removed all the other system-scoped dependencies, as it should be. Let's see if the build works with transitive dependencies. Signed-off-by: Alexander Kriegisch <Alexander@Kriegisch.name>
