• Is there an equivalent of "OPTION(RECOMPILE)" or "WITH RECOMPILE" for an entire connection?

  - by kamens

  I'm curious. Is there any way to prevent SQL query execution plans from being cached for an entire connection's duration? Can I run a command that basically says, "use OPTION(RECOMPILE) for all subsequent commands until I tell you to stop doing so?" I'm acutely aware of all the performance trade-offs here, and I know this is not a step to be taken lightly. However, I'm in a unique situation where this behavior may be advantageous.

• What does SQL Server trace flag 253 do?

  - by kamens

  In another question I was trying to research how to control SQL Server's query plan caches: http://stackoverflow.com/questions/2593749/is-there-an-equivalent-of-optionrecompile-or-with-recompile-for-an-entire-c ...and I found trace flag 253 via this article: http://www.sqlservercentral.com/Forums/Topic837613-146-1.aspx The article is correct, if I run DBCC TRACEON(253) and then a number of queries, I can manually check the query plan cache and see that plans have not been inserted. If I run DBCC TRACEOFF(253), query plans are cached as normal. So my question is...what else does this flag do? Does anybody know the official story?

• What are all the valid self-closing tags in XHTML (as implemented by the major browsers)?

  - by kamens

  What are all the valid self-closing tags (e.g. <br/>) in XHTML (as implemented by the major browsers)? I know that XHTML technically allows any tag to be self-closed, but I'm looking for a list of those tags supported by all major browsers. See http://dusan.fora.si/blog/self-closing-tags for examples of some problems caused by self-closing tags such as <div />.

• GAE app.yaml appears to be inconsistently routing requests

  - by kamens

  I have the following in app.yaml: - url: /gae_mini_profiler/static static_dir: gae_mini_profiler/static - url: /gae_mini_profiler/.* script: gae_mini_profiler/main.py - url: .* script: main.py and the following in gae_mini_profiler/main.py: def main(): logging.critical("gae_mini_profiler request!") run_wsgi_app(application) However, when I fire requests to, say, /gae_mini_profiler/request?request=ABC, and repeatedly reload the page, sometimes I will get the proper response (as well as a "gae_mini_profiler request!" log entry, and sometimes I get a blank response and nothing in the App Engine logs other than a 200 with an empty response body. This is completely reproducible, only happens in the live environment, and I'd say ~50% of the refreshes work while 50% do not. This only happens in production. Any ideas?
