Hi, Although I'm pretty sure I fixed the problem of the memory manager (in zend_alloc.c), I agree with Sterling that it's probably best to disable it for 5.0.0. I don't think that my fix will get enough testing until then for me to feel comfortable with including it. As I'd like to roll 5.0.0 by the end of the week, can developers please speak up if they have anything critical they are working on? Please also run latest head just to make sure that the malloc()/free() MM still works :) Andi

Is this with ZEND_MM or without? Andi At 07:17 PM 7/5/2004 +0200, Christian Stocker wrote:

Sorry about my ignorance, but I don't know ;) standard ./configure (with some extensions) on OS X ... chregu On 5.7.2004 19:48 Uhr, Andi Gutmans wrote:

I'd like to see a few people who know their way around Valgrind give this thing a workout before any release. I am planning on doing that as well this week, but the more codepaths tested, the better. -Rasmus On Mon, 5 Jul 2004, Andi Gutmans wrote:

yes!!! i currently don't have a 32 bit linux box available to me (i'm remote in ca for all of august), however, if someone gives me shell on one, i'll bang around on it with valgrind. -sterling On Mon, 5 Jul 2004 11:13:12 -0700 (Pacific Standard Time), Rasmus Lerdorf <rasmus@php.net> wrote:

I think sterling's looking for an OS X port. How is y!'s (inf)famous freebsd port of valgrind coming along? Rasmus Lerdorf wrote:

It's not really Y's port. We just helped it along a bit. Doug Rabson is the person you are looking for. See http://www.rabson.org/ -Rasmus On Mon, 5 Jul 2004, George Schlossnagle wrote:

i thought my valgrind was bork but wow it works after reverting to an older snapshot of the virtual machine :-) in the output there are 13281 errors from 4 contexts regarding missreads near constants. I tried to solve this again and gain and again but maybe i am blind. Apart from that i see some problems with internal classes. Note that this is a ZTS build. I know that for a short time some time ago i did not experience this. Anybody see those with non ZTS too? regards marcus marcus@frodo /usr/src/php-cvs $ valgrind --tool=memcheck --leak-check=yes --show-reachable=yes --num-callers=30 sapi/cli/php -r 'echo "Hello\n"

This is completely broke: file_get_contents('http://php.net/'); It returns partial content. See bug #29099 Curt

Just rechecked with current CVS version this morning and the problem still persists. Not only is it comming back with partial content, there seems to be blocks of ^@ chars between the content. Curt

Could you give a small reproduce script ? I tried it on local and remote files and it works ok for me. --- WBR, Antony Dovgal aka tony2001 tony2001@phpclub.net || antony@dovgal.com

Its simply: <?php echo file_get_contents("http://php.net/"); ?> I rechecked this with a fresh compile from snapshot of php5-200407121630. It still occurs for me. It seems to work fine for regular files and small web pages but breaks when content from a webpage becomes a certain size. Curt

More info please... how big is a "certain size"? How about running "strace -e trace=net" ? Even better, can you sit down and step through and find out where the read is being cut short? The thing is that file_get_contents() should not have been sensitive to the greedy read problem (since it reads in chunks anyway), so this doesn't make too much sense to me right now (but I've only spent 5 minutes looking at it; got a lot of work on). --Wez.

for me, the "certain size" is right at 12kb. 12,000 bytes es ok; 12,001 no es ok. i would trace/step if i knew how.
