Is there a URI where the old documentation is available ? or does the used need to download it and then pass the location using -D to the diff target ?
> Is there a URI where the old documentation is available ?
There are public URIs where released javadocs may be obtained, but I don't think JDiff uses the normal javadoc, but rather special javadoc output that it generates. Please see LUCENE-1083 which addresses this further. I had a look at the patch LUCENE-1083. Looks like Jdiff requires 2 sets of java code.
We have one set of java code (current / latest) in the svn tree, from where do i get the "OLD" one ? e.g. if I need to run jdiff today i will have trunk checked out onto my machine (and the current version in trunk is 1.6 ). Now I want to Jdff the trunk and 1.3 .. where do i get 1.3 code ? Does the user need to download and then pass the path to ant with -D option ? > where do i get the "OLD" one ?
The approach I suggested in the Lucene issue was to have some ant properties that determine the subversion tag url of the prior version. In trunk this would point to the prior release. We'd update it in trunk after each release is made. Then the ant build script would check this out in build/ if it didn't already exist there. We could (and should) permit this to be optimized, perhaps by permitting folks to override a property so that the prior version is stored somewhere more permanent than build/, and perhaps use 'svn switch; svn update' to make sure that the cached prior version contains what we expect. > Does the user need to download and then pass the path to ant with -D option ? I'd imagined that specifying -Djdiff.prior.dir would be optional, but would help performance a lot, but we could make it mandatory, and emit an error if it's not specified. That might reduce the load on subversion somewhat.
Yes, I would like to make -Djdiff.prior.dir mandatory .. Please comment Try out the attached patch
The correct way to run the jdiff target is (You will need to chage the values as per your environment) ant -Djdiff.prior.dir=/home/hadoop/myprojects/hadoop-0.13/src/java -Djdiff.prior.version=0.13 -DJDIFF_HOME=/home/hadoop/JDiff/jdiff-1.1.0/ jdiff Should we target this for 0.18.2 and 0.19.0?
This better integrates jdiff into our release build process. After this is applied, if one adds the 'api-report' target to release builds, then jdiff output will be included in the documentation. Once this is committed I will update the HowToRelease page in the wiki.
To test this:
Then browse build/hadoop-X.Y.Z/docs (the candidate release build) and look for the "API Changes" link. I just committed this to both branches, and also updated the HowToRelease page in the wiki with instructions on how to generate the jdiff documentation.
