Re: [PHP-DEV] Reducing the number of system calls for includes
Weird. That was totally contrary to the way I remember it working. In trying to figure out why I remembered incorrectly, I realized the reason why you (in general) want to resolve the path to a canonical path is that you can seriously break include_once and require_once if you dont. Otherwise require_once wont correctly work if you do ? require_once(/home/george/foo.php); require_once(/home/george/../george/foo.php); ? Right, but guarding against this edge case is costing us a lot on the normal case. 100,000 realpath() calls on Linux on file /home/rasmus/foo/u2.inc: real0m1.286s user0m0.190s sys 0m1.030s 100,000 stat() calls on Linux on file /home/rasmus/foo/u2.inc: real0m0.421s user0m0.070s sys 0m0.290s The deeper the directory hierachy, the larger the difference. On FreeBSD we get slammed! Looks like they don't have the same dcache-like thing that Linux has. 100,000 realpath() calls on /home/rasmus/foo/u2.inc on FreeBSD: real0m51.274s user0m6.752s sys 0m26.478s 100,000 stats() calls on the same file on FreeBSD: real0m8.873s user0m0.165s sys 0m8.042s So yes, it does look like we don't need to worry too much on Linux, but clearly on FreeBSD avoiding stat() calls and calls that create cascading stat()'s are to be avoided at all costs. -Rasmus -- PHP Development Mailing List http://www.php.net/ To unsubscribe, visit: http://www.php.net/unsub.php

?
But when i'm using IF Else.. Nothing is happening. I'm only seeing the form but when i
submit that form: The $vname doen't display..
Here is the code that doesn't work:
?php
$vname=$_POST['vname'];

Yes you are right. But I still think the advantages of having a canonical
file path is good. It improves error messages, it allows for open_basedir
and include_once() to work 100%. I don't think it's worth killing good
stable functionality for this.
What needs to be taken from your timings is not the relative time of stat()
vs. realpath() but the absolute times. You can see that on Linux the speed
of realpath() is 12 microsecond. I don't believe you can feel this in a
script even if you have tens of realpath()'s per script (at least vs.
stat()). Now on FreeBSD it takes about half a millisecond. That is much
more but I'm not sure it's still worth breaking functionality for this.
That said, we could possibly have a fast mode and use fstat() to get some
device information on the open file. I am worried about functionality
though. I'm not sure it's worth breaking.

Re: [PHP-DEV] Reducing the number of system calls for includes
The question here is whether it's worthwhile to optimize for the case where you have 30+ includes per page. Is it that common? In my particular case just 2 or 3 includes puts me over the top actually. stat() is amazingly slow on freebsd and having 3 includes of files in a directory 8 levels below the root is going to do 27 stat()'s. 27 stats on my freebsd box here takes 24ms to execute. That's a long time to be sitting around stat'ing things. And heaven help me if the path is not absolute and I have to try different include paths. And if open_basedir is also enabled you might as well go for a coffee while you wait through some 80+ syscalls for every include. -Rasmus -- PHP Development Mailing List http://www.php.net/ To unsubscribe, visit: http://www.php.net/unsub.php

The question here is whether it's worthwhile to optimize for the case where you have 30+ includes per page. Is it that common? Yes, I'm as a PHP-developer (developing _with_ PHP :-), I can say, my site has a well-organized dir-structure, I uses a _lot_ of includes, in some requests, it's over 30 (it's depends on the request, because i use a main script as a wrapper for other scripts..) I think that sites where this actually matters should employ some form of preprocessing for their scripts where include/require directives get interpolated by the contents of the respective file. This can be easily implemented either in about 50 LOC of PHP or sh/awk. That won't work of course, if you rely heavily on dynamic includes where the filename is determined at run-time. WKO preprocessing do you think?

I think the best solution to this problem, without breaking functionality, is to use a cache for realpath() in virtual_file_ex(). This should solve the performance problems and not effect BC at all. As TSRM always passes a full path to the realpath() call there, it should always work. Perhaps make it configurable because on Linux there already is a dcache right in the kernel which is likely to be faster than anything we can do.

[PHP-DEV] Adding to the bundled GDlib
Hi list. I want to gratulate you for finally including the GDlib as a bundled extension to PHP and recognize that the Boutell people has apparently stalled the development... Now it also seems like new PHP/GD-only functions are sneaking in (there is a imagelayereffect and imagecolormatch function added) and that is even better! I have now played around with GD for the last few days and added around 10+ new vital functions which are must-haves for what must be tons of people needing a truely powerful graphics manipulation engine. I'll tell you more about those functions and demonstrating them by a demo-website soon. But my actual request is this: - Who is in charge of the bundled GD? (Who can I discuss it with) - What is the policy on that library? Do you want it to be expanded with new functions? - Would you be positive towards additions from me? (I want to know this before I spend more brainpower) - How can I help? (I'm new to this list but is a very experienced PHP programmer since PHP/FI 2) I really want to help the development of the bundled GD to be a powerful image manipulation package. For now my changes are simply additions and I'm going to supply full documentation of the API and possibly also offer a public testsite for the demonstration.

I'm creating a site which is quite an extensive, you know, I mean great, well-organized directory structure, etc.. As I always think, if the scriptfile is growing above 10k, i should split that into two or more files if the functions are alternative, in order to save some CPU cycles by not to process the whole file in vain. But as I recently red, the require takes up a LOT of CPU cycles. So, my question finally is: What is that filesize, above which is _recommended_ to split files into parts?

Re: [PHP-DEV] php_stream size
At the moment, what you are currently doing is one of the simplest ways of doing it portably, provided that the stream is seekable. The other way is to call php_stream_stat() which returns the size, ctime, mtime etc. of the stream, and can theoretically work on virtual filesystems and wrappers (if those things implement the stat op, that is!). This is perhaps a better solution because the HTTP wrapper could (but does not yet) provide the Content-Length information in the size field of the stat structure (of course, the remote server might not send a Content-Length header, so no size information would be present). At the end of the day, the correct solution for your code depends on what your code is trying to do; not all streams are seekable, so the stat option is better, but then, stat is not guaranteed to return a sensible size (or even any information). If you are working on the stream in read-only operation, you can open the stream using the STREAM_MUST_SEEK flag; this will cause the streams layer to determine if the stream is seeekable; if it is not, it will copy the stream into a temporary stream which is seekable. (The temp stream is implemented as a memory buffer when the data are below a certain threshold; when it gets too big for memory, it will automatically use a temporary file for storage). So you will be guaranteed that seek (and stat) will work on the stream, but not guaranteed to be working with the actual resource you requested. (Hence the reason that it is not suitable for read/write mode). I hope that has helped! --Wez.

No. zlib is included in a similar way to the way we include bindlib_w32. It's in a different repository on cvs.php.net, that we expect to be checked out and built by the time you build PHP. Ok, from users point the same... Maybe my question was a bit misleading, I meant provided within win32build.zip, maybe. 2.) Should users be advised to modify config.win32.h.in Nope (this particular file doesn't exist anymore, btw) Hm, you are right, at least not in the snapshots, but in the official release 4.3.0 from php.net... anyway. 3.) Should users be advised to download zlib sources, building zlib.lib? Not sure - I think that zlib should be in the win32build.zip archive. Nope;-) As zlib is builtin and the workspaces rely on, it would be really nice for users if they are done by downloading php4.xxx.tar.gz, win32build.zip and bindlib_w32.zip, the way like other standard builtin modules are fine with. I'm not really following. I have to admit I never built PHP from the pre-made library binaries, so it sounds awkward to me. Are we making people download the bindlib source and build it? If so, we should do the same with zlib (looking into it, I guess it means creating a zlib.zip file, like bindlib_w32.zip). zlib and bindlib sit in exactly the same level of integration with PHP. To me it sounds a bit weird that the ready-made builds of these libraries don't come bundled in win32build.zip, but I guess that's fine as long as it's documented.
