First I want to thank you for this plugin. It's great and this is the first problem I encounter, since I use it. I guess, thats, why there no bugs in the bug report list. :)

When I make a persistent connection to a database file, the database file will be locked for filesystem operations like move or delete, until I restart the webserver.

I think, the problem to this is because php doesn't free the resources of the persistent connection. I am aware that this is the normal behaviour for persistent database connections in php.

The normal solution to this problem is to free the resource on the db-side or with a connection timeout(never tried it) in php. Unfortunatly neither of them work with sqlite since there is no server or connection timeout directive.

I don't know if this is known or even intended behaviour. I'm sorry, for this (miss)post if this is not a bug. 

I tried it with php 5.1(precompiled sapi for apache2) (4 days old) and sqlite included with it ( and of course I uncommented the extension directives to enable pdo and sqlite modules in php.ini). I dont know if this problem does exist in other versions. But I expect, that this issue exist in all but the cgi version of php.

thank you in advance,

P.S. This is my very first bug-report and english is not my native language. I appologize for any inconvenience resulting from that.

Reproduce code:
$handle = sqlite_popen('persistent.db');

Expected result:
The database file can be deleted/moved after execution of the code (or at least some timer after execution).

Actual result:
The database file persistent.db cannot be moved/deleted, until the webserver restarts. There appears no default connection-timeout for idle connections. (I waited almost a day for a connection-timeout.)

This isn't cute! How do I get this off my computer? Looks like someone is running data through my computer.  I want it gone, now!  Tell me how, or I'm reporting it

This will [likely] never be fixed. This PECL extension is no longer maintained, and I doubt ever will be. Instead, use the well maintained sqlite extension that comes with the PHP sources.

The sqlite pecl page has been updated to reflect this.
