Subject: Script is usable!
X-Git-Tag: V1_1_0~34
X-Git-Url: https://source.dussan.org/?a=commitdiff_plain;h=a0d2d2d0de4ab0e67a714d3fec46d96b268ca1e4;p=aspectj.git

Script is usable!
- lots of rearranging and cleanup, docs
- now doing 1.3 and 1.4 testing
- more harness tests (some unverified)
- workaround OOM in examples
- cleanup after building-aspectj-with-aspectj

need more integration with manual process

+ Normally this builds with Java 1.3 and tests with both
+ Java 1.3 and 1.4, so define both as properties. You
+ can select any target (not prefixed "do-" or "init-").
+ The leaf targets will run with Java version set in 
+     ${java.home.file}
+ When running non-leaf targets, if you want to test
+ only in 1.3 or 1.4, set property "run.1[3|4].only". 
+
+ Properties to consider setting on the command-line:
+
+    -- required 
+    java13.home           JAVA_HOME for latest J2SE 1.3
+    java14.home           JAVA_HOME for latest J2SE 1.4

+
+This script builds and tests an AspectJ release.
+Use the info target to emit details.
+
+At the bottom is a bash script to run it.
+
+---- Evaluating the results of a build cycle
+
+There is a ../release-checklist.txt which has steps for a release, some of 
+which are automated in this script.  Try the others ;).
+
+Known issues with these tests
+
+- ajc compile of tjp example as part of nonGui target
+  runs out of memory.  Reproducible on the command-line: 
+      [ajc] Running  in-process using -verbose -d R:\home\wes\ec\aj-
+build\install\doc\examples\classes -classpath R:\home\wes\ec\aj-buil
+d\install\lib\aspectjrt.jar -argfile R:\home\wes\ec\aj-build\install
+\doc\examples\tjp\files.lst
+Exception reading component R:\home\wes\ec\aj-build\install\lib\aspe
+ctjtools.jar
+java.lang.OutOfMemoryError
+        <<no stack trace available>>
+Exception in thread "main" java.lang.OutOfMemoryError
+        <<no stack trace available>>
+  
+  This target is run without failonerror="true" to complete
+  the testing.          
+  
+Known imperfect results in the AspectJ 1.1 release:
+
+- ajdeCompiler tests will have five known fails, listed
+  in releases/aspectj1.1/ajcTests-ajdeCompiler-FAIL.txt
+  
+- under 1.4, the junit module test output for the weaver
+  module is corrupted - the last two characters are 
+  duplicated, which cause the junit reporting task to
+  not pick up the weaver tests.  Verify that the 
+  weaver XML file lists no JUnit failures or errors.
