These are old issues ...

I can not reproduce this with PHP CGI/CLI/Apache DSO,
but Steph tested the script under windows and
got the same results as ce...@mail.ru did so this is
definately a windows-only bug.

I tested your script. The output is:
PHP Fatal error: Maximum execution time of 1 second exceeded in
c:\exp.php on line 16
PHP Fatal error: Maximum execution time of 1 second exceeded in
c:\exp.php on line 7
"test.log" contains only one "Start" line.
I tried with both my own (pretty much cleaned up) php.ini and
"recommended" php.ini.
I suspect it is only Windows-related problem.

#21513 [Com]: shutdown functions not executed if timed out
ID: 21513 Comment by: jsphp at kanargh dot force9 dot co dot uk Reported By: ceeam at mail dot ru Status: Assigned Bug Type: Scripting Engine problem Operating System: win32 (only) PHP Version: 4CVS, 5CVS Assigned To: zeev New Comment: HUP. Just came across this today. As the leading comment says, this is really bad for DB transactions. I had originally assumed that when a page dies for whatever reason, in the middle of an uncommitted transaction on a non-persistent pgsql connection, the transaction would be rolled back - but in fact it is implicitly committed. (So a series of many INSERTs will be half-complete, and you can't just hit Back and try again 'cos you'll get duplication.) This is bad enough - unclosed transactions ought not to be committed if you don't know whether they were complete or not - in fact only an explicitly coded COMMIT statement should change the database state. So I looked through the help and found register_shutdown_function, implemented one and relaxed again. Only to find that the timeout causes the shutdown function to abort too, so there doesn't appear to be any way to not balls up the database :-( Does PHP itself complete the transaction, or is it likely that PostgreSQL is doing this itself when the connection is dropped? If the former this is another bug in PHP, if the latter (which given the lack of PHP API support for transactions seems likely) I may well throw it over to their bugtracker too. But the register_shutdown_function issue does need fixing.
