[google-appengine] Resizing Image with Stretching
I'm using the Image class to work with an image. When I call image.resize(width = new_width, height = new_height), it seems to honor either height or width, but not both. That is, the method maintains the original aspect ratio without stretching. Is there a way to stretch an image?

[google-appengine] My logs are starting to bite into my storage quota. Can I reclaim this space?
In my testing this morning, I've generated quite a few messages in my logs. I see that these apparently count toward my storage quota. Is there any way to reclaim this space?

[google-appengine] Re: Dashboard - Logs - How to clear them? - What is the Date-Time reference?
Is this still the fact? I'd bet my house that logs count against quota because this AM I was at about 0.5 MB of disk usage. I created *lots* of log messages and ended up around 1.1 MB used with only a few new data store entities.

Yes, this is entirely possible. I did a lot of creating and deleting because I was doing load testing. Will that space be reclaimed?

[google-appengine] Re: Is Memcache really needed?
One cool application of memcache: I have an RPC application that hits remote functions maybe once every few seconds per user. Part of my security scheme involves matching user ids to session keys. Hitting the data store for this on every call eats resources, but memcache brings a lot more efficiency.

[google-appengine] Global Variables / Caching Question
Forgive me if this is a FAQ, but I did a little searching and did not find an answer. According to http://code.google.com/appengine/docs/python/appcaching.html, GAE caches global variables in imported modules between requests. I've got a global dictionary in a module that I'm sharing between requests. Is such a dictionary "thread safe"? In other words, if multiple users are hitting my application simultaneously, and both may be using the same global dictionary, am I going to encounter problems, or will GAE handle the situation gracefully? Thanks for any help. (By the way, I know that the dictionary may eventually disappear or get recreated unless I write its information to the data store. That's okay in the case I have in mind.) -- http://giscoder.blogspot.com/ --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.

[google-appengine] Re: Hardly anything stored in appengine - already 10 MB gone?
Your not hallucinating. I've seen the same kind of problem. Apparently there is a known issue where space is sometimes not reclaimed after you delete a data store entity.

[google-appengine] Re: What is a proper way to cache values on "per request" basis?
Try getting rid of the memcache in favor of a hard-coded value (for testing purposes only). If you're still getting high CPU usage, then the problem is not with your use of memcache. You can also use global variables to cache values, as long as you're careful.

Here's a little function I wrote that you may have:

cents = amount - dollars
i = 0
reverseDollarPlaces = []
for p in str(dollars)[::-1]:
if i % 3 == 0 and i:
reverseDollarPlaces.append(',')
reverseDollarPlaces.append(p)
i += 1
return '$%s.%.2i' % (''.join(reverseDollarPlaces[::-1]), int(100*cents))
