[retronym]

@lrytz It's the first time I've done this. Thanks for the great instructions. Could you check I've followed them correctly? I haven't done the work of reviewing the diff in ASM in full yet, I remember you'd started that process.

My branch is at https://github.com/retronym/scala-asm/tree/s-6.2

[lrytz]

Could you replace the commit retronym@7299c39 by an update to scripts/gitignoreSelectFiles in retronym@d324049 ?

[lrytz]

Wow are there really 532 comits between 6.0 and 6.2 !?!

[lrytz]

Something looks wrong; your branch seems to build on top of https://github.com/scala/scala-asm/tree/ASM_6_0, not 6_2.

[lrytz]

The scripts will need some updating, because the repository structure changed quite a bit between 6.0 and 6.2

[retronym]

I've redone the rebase, updating the gitignore and scripts and merging the asm-cherry-pick commits.

The branch still needs a round of cleanup, and a few changes in scala/scala, but it looks to be passing the test suite.

The upstream code has been through a reformat, so just about every patch required some manual work. Above that, there have been some renames and some structural changes that required some careful merging.

[retronym]

@lrytz This branch is ready for a final round of review. scala/scala#6733 contains the compiler changes.

[lrytz]

Looks good, thank you for solving all the conflicts! The script changes can be squashed.

[mkurz]

Maybe it's time to try to get all the patches into the official asm repo?

[lrytz]

See https://gitlab.ow2.org/asm/asm/issues/317828#note_36176

[retronym]

@lrytz I tried to cut tag and release, but ran into a problem with the release script: https://travis-ci.org/scala/scala-asm/builds/389051634

$ jdk_switcher use openjdk6
Switching to OpenJDK6 (java-1.6.0-openjdk-amd64), JAVA_HOME will be set to /usr/lib/jvm/java-6-openjdk-amd64
update-java-alternatives: directory does not exist: /usr/lib/jvm/java-1.6.0-openjdk-amd64
...
...

17.77s$ sudo -E apt-get -yq --no-install-suggests --no-install-recommends --force-yes install openjdk-6-jdk
Reading package lists...

In the last released build, jdk_switcher has the same error, and also preceded the apt-get, but JDK6 seemed to be on the path by the time the build ran.

[retronym]

scala-asm 6.2.0-scala-2 is now released. I worked around the JDK6 problem on Travis by using JDK8 to build.
