I am cross-posting this message from the sourceforge bugtracker, so that everyone will know about it. Perhaps someone will have a clue what might be causing it. It's pretty weird... v v v v v v v v v v v From: SourceForge.net <nore...@sourceforge.net> Subject: [ pywin32-Bugs-3292681 ] adodbapi - Subtle crash To: nore...@sourceforge.net Date: Tuesday, April 26, 2011, 3:11 PM
Bugs item #3292681, was opened at 2011-04-25 15:51 [... snip ...] Category: adodbapi Group: None Status: [Accepted] Resolution: None Priority: 5 Private: No Submitted By: https://www.google.com/accounts () Assigned to: Vernon Cole (kf7xm) Summary: adodbapi - Subtle crash Initial Comment: There is a subtle crash that can occur related to time.sleep(>10) and adodbapi.connect() calls, the second time will crash, attached there is the simplest test case to crash it and various comments explaining the crash behavior test enviroement and stacktraces. i hope will be useful to find the right solution, i've only found a bad workarond, without calling adodbapi.close() the crash doesn't happens. thank you in advice ---------------------------------------------------------------------- >Comment By: https://www.google.com/accounts () Date: 2011-04-26 21:11 Message: The connection string needs sqlserver express installed on the machine, but the same happens also with oracle oledb provider, this are the two providers i've tested on, but could be the crash occurs with any provider ------------------------------- Comment By: Mark Hammond (mhammond) Date: 2011-04-26 03:19 Message: I haven't had a chance to repro this yet as the connection string doesn't work on my dev box. ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ I have downloaded the code and determined that it also crashes on my Vista 32 bit laptop, running either Python 2.7 or 3.2. It also crashes when using the JET data provider to open an ACCESS .mdb database, so the problem is not specific to any provider. It DOES NOT crash when using IronPython. It DOES NOT crash if you have made opened and closed a connection for less than 10 seconds before you try it with the 10 second pause. It also crashes if the time.sleep(10) call is replaced by sys.stdin.readline() and counting ten seconds, so it's not an interaction with the time() module. I'll continue looking, but frankly don't have a clue where to start. Brilliant helpers are invited to contribute. -- Vernon WebRep Overall rating
