Temurin-build: OpenJDK local disk check not working on AIX

[gdams]

WARNING: Your build output directory is not on a local disk.
This will severely degrade build performance!
It is recommended that you create an output directory on a local disk,
and run the configure script again from that directory.

@sxa555 informs me that the check uses df -l which isn't a valid flag on AIX

[sxa]

The simplest way to resolve this may be to modify the PATH to include /usr/sysv/bin before /usr/bin as that has a version of df that supports the -l option. A less drastic approach would be to set DF='/usr/sysv/bin/df" to force configure to use that

[gdams]

hmm okay, fancy submitting a PR to auto export that env var if we are on AIX?

[sxa]

Hmm /usr/sysv/bin/df isn't quite working the same. Unless you specify the exact mount point as a directory (i.e. normally . or $PWD won't work as they're deeper down the file system) it doesn't give the expected result ... Still investigating

https://bugs.openjdk.java.net/browse/JDK-8189619 raised to fix this upstream

[karianna]

@sxa555 - The patch has landed upstream - can this now be closed or does that patch need to be backported.

[gdams]

We are waiting for this to be backported to 8 and 9. Not sure if any progress has been made with that yet.

[sxa]

@karianna Do you know if such things will get automatically backported by Oracle or will it need us to submit additional requests?

[karianna]

@sxa555 Separate back port requests will have to go into 8 and 9. I know that 8 has an updates project, but under the new world I don't think 9 will be getting any more patches so that's one we'll have to put into the AdoptOpenJDK derivative (if I've read all of the rules correctly).

It's worth pinging Thomas Stuefe and asking if he'd backport it to 8 for us (and 9 if that's possible, but see above).

[karianna]

@sxa555 Is this still important?

[gdams]

this bug has been fixed upstream
