Re: [PHP] spawing new PHP process
In article [EMAIL PROTECTED], Robert McPeak [EMAIL PROTECTED] wrote: I have other situations where I would like to somehow spawn a new php process so that the page loads quickly and my user doesn't get frustrated or confused. Hang on, there's lots of talking around the point here. This is not hard. Look in the manual under pcntl_fork. This will let you create a separate process that stays running all the time (not just when you're running a web page) and you can send commands to either using pcntl_signal (docs are out of date - also look up ticks) or through your database. You will need to have the CGI version of PHP installed, as well as mod_php - and in 4.3 this happens very easily. Having said all that, I've run into a separate probem further down the road doing just what you're wanting to do. My back-end process runs perfectly with no problems but after 5 mins or so starts generating chunk/page already free errors, then crashes. Looks to be a bug in there somewhere, but not sure where yet. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Building PHP extensions for MacOS X
I need to build a PHP extension that also talks to parts of the MacOS X API/frameworks. I could build simple, generic extensions in gcc, but for OS X APIs, I need to use something a bit bigger. Can anybody give me any tips of how to build PHP extensions in CodeWarrior or ProjectBuilder on MacOS X? Or perhaps a link to somewhere that might help?

[PHP] sysvshm examples?
Can anyone point me at some examples of using sysv shared memory, particularly for passing values between a mod_php script and a PHP CLI process? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Signal handling
Is signal handling broken in PHP 4.3-cvs? I've set up some handlers as per the docs, but nothing happens when I send appropriate signals. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Getting local domain name in CLI
I need to get the domain name of the local machine. I'm running a CLI script in PHP 4.3-cvs (on OpenBSD) so I have no HTTP or other global vars to look at. The posix_uname command doesn't include the domain on non-GNU OSs. I can get the hostname, but not the domain. Can I get it through some other PHP command? I'd really prefer not to resort to rummaging in /etc and parsing files or doing something silly like a DNS lookup...

[PHP] PHP and Transactions with InnoDB
I could use some practical tips on doing transactions with InnoDB tables in MySQL. I want to grab and lock a record and do a whole load of related stuff, then make sure everything is updated in a consistent way, something like this skeleton: BEGIN SELECT * from blah WHERE something=n FOR UPDATE //Grab and lock a record SELECT * from t1, t2 where a=1 ... INSERT blah... UPDATE something else... if ($allok) COMMIT else ROLLBACK I don't quite get what I need to do to make sure these are all regarded as part of the same transaction. Does the transation apply to all queries made between the begin and commit (I assume so)? What happens when I have another process doing the same thing at the same time? Do I need to keep the result value I get from the begin query and somehow use it for the commit at the end so MySQL knows they are two ends of the same transaction? Or does MySQL somehow track that for me - i.e. can there only be one transaction in progress per connection? I'm finding the MySQL docs are extremely dry and somewhat short on examples... -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] PHP and Transactions with InnoDB
In article [EMAIL PROTECTED], Miles Thompson [EMAIL PROTECTED] wrote: I've not worked with InnoDb, but given that the web is a stateless space and all kinds of things can happen, I'd be very reluctant to lock a record until the very moment I'm updating it. In other words, when I have my batch of updates and inserts ready to go, then I'd begin by transaction, execute them, and do a commit or a rollback. I should have mentioned: it's not actually running behind a web process but as a stand-alone CLI process in PHP 4.3-cvs, so it's not quite as subject to the vagaries of web accesses. At the moment there's really only one process involved, but I'm intending to expand it later, hence this query. I see what you're saying, but the problem I have is that the results of the intermediate queries are dependent on me having control of the master record, i.e. If I make them without the master record being locked, by the time it comes to posting them back to the database, they may be meaningless, so I need to make sure that the state of the database is consistent throughout all the queries, as if I was the only client. Isn't this the whole point of transactions? Is ther any particular problem with having transactions that take a while, say 10-20 seconds overall? I suspect I'm just not quite clear on exactly the relationship between record locking and transactions. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Re: Getting local domain name in CLI
In article [EMAIL PROTECTED], Philip Hallstrom [EMAIL PROTECTED] wrote: What about... $hostname = `/bin/hostname`; or something along those lines... Well that's rather the kind of thing I was wanting to avoid - it's much akin to rummaging in /etc. the hostname command gives me my hostname ONLY (like www), much as the posix_uname function does, but on my system (OpenBSD 3.1) the corresponding domainname utility returns nothing (as I'm not using YP), so I still can't seem to find this out from PHP.
