* BcelObjectType: Add experimental code to set source file name forAlexander Kriegisch2024-04-131-4/+13
| | | | | | | | | | | | | reference Experimental code leading to undesired ripple effects elsewhere, requiring more rework which now I do not feel inclined to invest to perfect source file string representation for post-compile binary classes and aspects. Relates to #218. Signed-off-by: Alexander Kriegisch <Alexander@Kriegisch.name>

* Revert WeavingAdaptor generated class map optimisationAlexander Kriegisch2024-04-081-0/+1
| | | | | | | | | | | | | | This was introduced in commit 8a4aa03845 of PR #278 contribution as part of the #279 fix. The contributor thought that the generated closure class entries were never used, but in fact AJDT class OSGiWeavingAdaptor relies on the presence of those entries. To the best of my present knowledge, it looks as if this change was the root cause of https://github.com/eclipse-aspectj/ajdt/issues/57. Therefore, I reverted it, simultaneously refactoring Iterator::remove usage to delete entries from the map to Collection::removeIf. Signed-off-by: Alexander Kriegisch <Alexander@Kriegisch.name>

* LangUtil: remove methods like 'is11VMOrGreater', 'is1dot5VMOrGreater'Alexander Kriegisch2024-02-195-8/+8
| | | | | | | | | | Replace them by a uniform method 'isVMGreaterOrEqual(double)', also overloaded for int. This gets rid of one 'AspectJ_JDK_Update' tag. One less place to check and update with each newly supported Java version. :-) Signed-off-by: Alexander Kriegisch <Alexander@Kriegisch.name>
* Globally replace "http:" by "https:" in non-XML filesAlexander Kriegisch2024-02-153-6/+6
| | | | | | | | | Maybe, the XML files and Maven wrapper files will follow. First, let us find out if this breaks the build, maybe some tests are asserting on "http:". But there, the replacement would also have taken place, so probably it just works. Signed-off-by: Alexander Kriegisch <Alexander@Kriegisch.name>

* Store only weaved class names in the generatedClasses mapUri Simchoni2024-02-081-1/+0
| | | | | | | | | | | | | | | The generatedClasses map contained both keys of woven classes that had generated classes associated with them, and the keys of the generated classes themselves. It seems like this map is never consulted for the generated class key - the generated class is generated from within the context of woven class loading / retransformation, and thus no transform event is generated for it by the JVM. Because of that, we do not need to guard against re-weaving it. Other uses of generatedClasses map are for full/empty tests, where the woven class key is sufficient. This change simplifies deletion of a class because we do not have to look for its associated generated classes. Relates to #279.
* Remove WeavingAdaptor.couldWeave()Uri Simchoni2024-02-081-9/+1
| | | | | | | | | | | | WeavingAdaptor.couldWeave() tested two things: whether this specific class (by its name) should be excluded from weaving, and whether the class has generated classes associated with it (in which case we avoid weaving to avoid re-creating those generated classes). However, if the class has generated classes associated, couldWeave() is not called at all because of the new wovenWithGeneratedClass() test, so we have only the name test which is now called directly. Relates to #279.
* Use previous weaving result if classes were generated during weavingUri Simchoni2024-02-081-1/+24
| | | | | | | | | | | | | | | | | | | | | | A parallel-capable class loader might load the same class multiple times in multiple threads, see https://docs.oracle.com/javase/7/docs/technotes/guides/lang/cl-mt.html. In this scenario, the JVM instrumentation mechanism invokes the AspectJ weaver twice on the same class. In simple weaving scenarios, this would just cause weaving logic to run multiple times and produce the same result for each thread, but if the weaver is generating new classes, it is undesirable to generate those classes multiple times. To avoid this, the generatedClasses map in WeavingAdaptor keeps track of classes for which inner classes were generated and avoids re-weaving them. However, before this change, if a class was found in the generated map, the weaver would return the un-woven bytes, which would cause AspectJ not to work for some of the threads. This change returns the woven bytes instead of re-running weaving. Fixes #279.
* Change value of woven class in generatedClasses mapUri Simchoni2024-02-081-1/+1
| | | | | | | | Store the woven class and not a generated (inner) class as value of the woven class name. This has no effect in this commit, because the value is not consulted at all, but will be used later on. Relates to #279.

| | | | | | Relates to #277. Signed-off-by: Alexander Kriegisch <Alexander@Kriegisch.name>
* Weaver returns null instead of original bytes for unwoven classesAlexander Kriegisch2024-02-072-19/+28
| | | | | | | | | | | | | | | | | | This change makes sense independently of #277, but also enables using - cp "my.jar;aspectjweaver.jar" -XX:+AllowArchivingWithJavaAgent -javaagent:aspectjweaver.jar while creating a CDS archive. Afterward, the application can be run in its woven state from the CDS archive even without '-javaagent', because the byte code was archived in its woven state ("poor man's AJC"). See https://github.com/eclipse-aspectj/aspectj/issues/277#issuecomment-1931142753 for details. Fixes #277. Signed-off-by: Alexander Kriegisch <Alexander@Kriegisch.name>
* Workaround for defining classes during LTWAlexander Kriegisch2024-01-291-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | Overhaul ClassLoaderWeavingAdaptor to use statically initialised Unsafe instances and method handles pointing to their 'defineClass' methods. Those now work universally on JDKs 8-21. In older JDKs, the method used to be in sun.misc.Unsafe, in more recent ones on jdk.internal.misc.Unsafe. It is challenging to fetch instances, especially as reflection protection and module boundaries have been increased in the JDK progressively. But finally, a solution was adapted from Byte Buddy (BB). Kudos to BB author Rafael Winterhalter. The previous solution to use ClassLoader::defineClass and require '--add-opens' is no longer necessary for the first time since it became necessary in AspectJ 1.9.7 with Java 16 support. Add org.ow2.asm:asm-common as a dependency everywhere org.ow2.asm:asm was used before. Maybe that is too many places, but no worse than before. Add missing dependency on loadtime to aspectjweaver. This kept a build like "mvn install -am -pl aspectjweaver" from picking up changed loadtime classes. Fixes #117. Signed-off-by: Alexander Kriegisch <Alexander@Kriegisch.name>
