Mumps!

Mumps! 12/17/2004 06:33 PM

I've become yet another statistic in the Bath Mumps epidemic of 2004. I'm quarantined until next Monday, and this afternoon we had a camera crew from ITV West come round to film some doom-and-gloom footage warning students to get vaccinated. Amusingly the camera man hadn't had Mumps and took suitable precautions to avoid infection. I'm told that the piece will go out on ITV news for the south west at 6pm this evening.

My First C Compiler

My First C Compiler 01/09/2004 09:56 PM

I accidentally googled into this short page on History of PC based C-compilers which made me think about my first C compiler: Aztec C on Apple II.  I was among the first wave of programmers who cut their teeth on PCs instead of minicomputers and state-of-the-art in PC software has risen high enough to make programming in assembly tedious.

So I just bought a copy of wonderfully thin K&R book which took only an hour to read and started writing in C.  I really liked it but I wasn't comfortable with the idea of using it for production code yet because size and speed still reign supreme then.  But it was fine for writing tools.

I think the first program I wrote with Aztec C was a double-hires image editor because that was when Apple IIc was about to be released and there were no tools to edit double-hires images.  It was sweet not having to worry about registers and being able to write almost English like code (well, it does when compared to assembly code).

Oh boy, time sure flies.

PHP Compiler Cache Internals

PHP Compiler Cache Internals 10/29/2003 12:11 AM
The latest English issue of PHP Magazine has an interesting article about implementing a PHP Opcode Cache by George Schlossnagle, the author of APC.

If you're familiar with the English expression, don't throw the baby out with the bath water, then you will be amused to learn that that's exactly how the Zend Engine (PHP's compiler) works. It will compile the PHP into opcodes for a page request, and throw the opcodes away immediately after the code completes.

This may sound really wierd and inefficient, but of course Zeev and Andi would not have been able to start their own company, Zend, without a business plan that involved fixing this "stupidity". And you thought Microsoft was evil ;-)

Now it is perfectly normal when developing a platform to leave gaps for commercial vendors to fill. That creates a ecosystem where we have companies willing to pay to maintain and promote PHP. So this isn't meant to be an attack against Zend, but an acknowledgement of business realities.

This omission of the Zend Engine stimulated interest in several open source developers to create their own opcode caches. APC is one of the earliest open source opcode caches.

In my benchmarks (yes, you see me benchmark a lot, because that's the only way to understand the performance profile of PHP software without spending a lot of time examining source code) I noticed that the overhead of PHP opcode caches was less for small scripts. Obviously there is some copying of instructions from the cache in shared memory during script execution. The question was how much? How did it affect performance?

Now we have the answer. George says restoration of the opcode info for script execution "involves only a so-called shallow copy of the op_array. A shallow copy means that only the structure itself is copied, but none of the elements it contains pointers to."

This means that the actual opcodes are not actually copied, only the pointers to the structures that contain the opcodes. Apart from that, the function and class metadata and any static variables are restored, and the inheritance hierarchy is dynamically resolved.

So the overhead of the opcode cache is O(n), where n is the number of functions+classes+inheritance levels+properties+PHP files. It is not proportional to the number of lines of code - that would be as worrying as throwing the baby with the bath water.

Another excellent issue of PHP Magazine!
