Hi Guix!

There seems to be a time bomb in icedtea@2 and openjdk@9. while
building it:

Error: time is more than 10 years from present: 1388527200000
java.lang.RuntimeException: time is more than 10 years from present:
1388527200000 at
build.tools.generatecurrencydata.GenerateCurrencyData.makeSpecialCaseEntry(GenerateCurrencyData.java:288)
at
build.tools.generatecurrencydata.GenerateCurrencyData.buildMainAndSpecialCaseTables(GenerateCurrencyData.java:227)
at
build.tools.generatecurrencydata.GenerateCurrencyData.main(GenerateCurrencyData.java:158)

I managed to work around that by setting the date back, but we should
investigate and fix it. icedtea@3 doesn't seem to be affected.

Confirmed:


This is with Guix commit 7a7c8920aeddaf9ab8d68c572780bc34b404711b.

I couldn’t find ‘GenerateCurrencyData.java’ though, not sure where it
lives.

Thanks for the quick investigation and patch! I just realized that this
affects current ‘master’ so we’d rather fix it soon.

What do you think of the attached patch? The difference is that it
patches code at its root (in the actual source tarball rather than after
it’s been copied), it does so for IcedTea 7 and 8, and there are patch
files that are slightly clearer than a substitution pattern.

It’s still building on my machine but if it works for everyone, I’d like
to push as soon as I got it built.

Ludo’.

Let’s hope there’s no similar time bomb elsewhere in the Java stack.

Thanks again,

That's clearly a much better solution than that substitution pattern of mine.

Besides, I missed the path difference:
jdk-3.19.0-2d5d2c77faa3:
/make/src/classes/build/tools/generatecurrencydata/GenerateCurrencyData.java
jdk-2.6.13-68b6bb380175:
/make/tools/src/build/tools/generatecurrencydata/GenerateCurrencyData.java

Speaking of which, I'd go for e.g.:
jdk-3.19.0-currency-time-bomb.patch
jdk-2.6.13-currency-time-bomb.patch
instead of:
jdk-currency-time-bomb.patch
jdk-currency-time-bomb2.patch

Yeah naming is hard ;-)

Also, changing the error string from:
time is more than 10 years from present
to:
time is more than 10 years from \"present\"

i.e. adding double quotes will slightly complicate googling for that
error message in the future.

Hi,

Thanks all for the quick fix.

Well, I am asking here but maybe such discussion would deserve its own
thread on guix-devel. :-)

This fixes the future but not the past. Hum, headache with guix
time-machine? :-)

The question is twofold:

1. Do we document that some Java stack is broken for “guix
time-machine”? Other said, have we an evaluation about which Guix
revisions are broken for the stack of Java?

2. Do we provide a “transformation” for fixing such break? Something
that rewrite on the fly the origin for patching it; accessible only
via manifest.

WDYT?

Cheers,
simon
