Strings in subsets

[Piero Campalani]

Subsets on temporal dimensions deserve a special treatment in order to let a user switch to ISO8601 notation.
Double-quotes for instance can be used to switch to ISO notation for temporal dimensions. Otherwise the default numeric coordinate is expected.

Patches applied for:

• (re-)allow quoted subsets (changeset:76b2b94)
• temporal trims in WCS request (changeset:800899d)
• fractional resolution when counting temporal units in time2index conversion (changeset:92d8164)

WCS test 29-* fails for me. Something is being repeated in petascope for about 10 times until it gives up, and the output is empty. In particular this is the output I see repeated for several times:

Man, you asked me if n.29 oracle was meant to be an exception: it is indeed, but the test fails due to #529.

[Dimitar Misev]

Ah I see, didn't realize that.

Who repeats the query for so many times, is it the systemtest or petascope?

[Piero Campalani]

That dtHead stuff is just a debugging log in TimeUtil, is not a repetition (you see the days are changing).
This can be nasty when you increase seconds over intervals of years.. see #505.

[Dimitar Misev]

If you do tail -f catalina.out while that test is run you'll notice the error and everything else is repeated for like 10 times, at least for me.

[Piero Campalani]

Sorry: too many tabs here.

[Dimitar Misev]

Yeah I was wondering about that conclusion

[Piero Campalani]

Closing this since strings in subsets are now working (see comment:1), enclosed in double quotes as by standard (see OGC 09-147r3, Sec. 6.4, NOTE.).

I'll open a new ticket to address the issue of verbose logging.

[Dimitar Misev]

I think the issue of verbose logging does not exist, as it's possible to control it in $RMANHOME/etc/log4j.properties?

[Piero Campalani]

Yes, but if the same procedure is repeated 10 times over a single request, there might be some performance issue there: I'll open a ticket with low priority so that I won't forget checking it.
