Re: GetOldestCaches issue

There appears to be an issue using GetOldestCaches when there is a minHiddenDate set in the filter. When it is set the following error appears:

Error 8, lua_callbacks.php:1525  Undefined variable: minHiddenDate

Example of working code can be seen here:https://project-gc.com/Challenges//62414
Non-working code is https://project-gc.com/Challenges//62415

The working code uses

testfilter={}
testfilter.country="United States"
testfilter.excludeArchived=true

mycs=PGC.GetOldestCaches({filter=testfilter,limit=1})

The non working code uses:

testfilter={}
testfilter.country="United States"
testfilter.excludeArchived=true
testfilter.minHiddenDate="1970-01-01"
mycs=PGC.GetOldestCaches({filter=testfilter,limit=1})

I started going down this road as an alternative to using GetNumCachesInArea to create a jasmer checker that will automatically notice missing months. Like GetNumCachesInArea the country required limitation will prevent a worldwide version. It still would be nice to specify for a single region so we do not need to manually update checkers as caches get archived.

You are correct, some copy paste issues, or maybe just not thinking enough when doing the code and sanitation for the filters. I'll fix them today and will try to release them tomorrow.

Parameter requiredFP was broken as well.

Much appreciated. I will test tomorrow.

I really

I have now released the code. Not tested, but it was very minor changes so I am quite confident it will work.

I didn't really get this part. I interpret it as you wish me to change something. If so, please explain again.

Like GetNumCachesInArea the country required limitation will prevent a worldwide version.

Let me experiment further with using this to make an "adaptive jasmer" for filters where some months are missing or a small number of caches away from missing. A virtual jasmer is such an example: Find a virtual cache in each month since the start of caching that has a virtual cache. Or a Large Jasmer is also such an example. Also regional checkers like https://project-gc.com/Challenges/GC2WMPX/23571 may require manual tweaking in the future.

Currently a world wide versions would be difficult as this call and the GetNumInArea both require a country. To do a full jasmer would require that both calls work fast enough to support a number of countries times number of months calls in under the time limit. GetNumInArea is too slow at this time to support something like one call per month since the start of geocaching.

Frankly my preference would be a faster worldwide GetNumInArea without a country requirement than this call. The nice thing about GetNumInArea being faster and without a country requirement would be that it would allow tailoring to a Jasmer to require months with only some number of caches remaining in the month and not require manual intervations as caches archive. So based on a current single jasmer 4 caches in a month may be set as the required threshhold.

So this is an observation that a further request could be coming shortly based on how experimentation progresses.

This is the sort of checker I am experimenting with. There are certainly optimizations to be made to this one to reduce the number of calls but the functionality is basically there.

So I have been kicking the tired on this version of GetOldestCaches. It appears to work generally ok.

Sometimes it does appear to return more caches than the limit. Functionally this does not seem to matter for me. However I am moderately concerned this has a performance impact.

A sample script is here https://project-gc.com/Challenges//62550
