Description:
PHP 5.1.6 compiled and installed without issues.
However when procedures call sybase functions and after few minutes.
PHP complain with not enough memory.
PHP seem unable to read all the script, also unable to address the
variables properly.
At beggining gave "fatal errors" due to lack of memory even with 200Mb
has memory limit (raised from its default value).
After recompiling php 5.1.6 for 2nd time, I'm now getting the following
errors, and lack of memory (200mb limit) message is now rare to appear.
Warning: Unknown list entry type in request shutdown (0) in
lib/lib_syb_sessions.php on line 61
Warning: Unknown list entry type in request shutdown (0) in

PHP 5.1.6 was compiled with the following parameters:

I have reviewed the procedure few times and I can't find any glitch
that could cause such behaviour.
I'm now compiling the latest 5.2* from dev's cvs to see if this issue
is solved. Cheers

#44208 [Opn->Bgs]: preg_* UTF-8 support breaks w/ external PCRE
ID: 44208
Updated by: [EMAIL PROTECTED]
Reported By: martin dot adolfsson at movel dot se
-Status: Open

Bug Type: PCRE related
Operating System: Debian GNU/Linux 4.0
PHP Version: 5.2.5
New Comment:
You've something broken on your end. I've compiled pcre with the same
options as you did and it worked correctly.
Previous Comments:

Might add some details from pcre-7.6:
pcre-7.6 configuration summary:
...
Enable UTF-8 support : yes
Unicode properties .. : yes
...
[src/pcre_tables.c]--
#ifdef SUPPORT_UTF8
const int _pcre_utf8_table1[] =...
.
[src/pcre_tables.c]--
$ strings lib/libpcre.a | grep pcre_utf8_table1
_pcre_utf8_table1
...
So AFAIK, PCRE has been built successfully w/ UTF-8 support.

Since the PDO code is identical for both Windows and Linux, I suspect

#44047 [Com]: IIS Worker Process stopped working
ID: 44047 Comment by: satan at dclxvi dot nl Reported By: matthew dot horner at redprairie dot com Status: Open Bug Type: IIS related Operating System: Windows Vista PHP Version: 5.2.5 New Comment: lol, your test is the solution... where you set it idle time out to 1 to test it earlier, just set it to '0'. it will error out once more and the next time it starts it will stay on.. there is no problem with leaving it on.. Previous Comments: [2008-02-29 04:37:22] nonya at spam dot this To elaborate on Matthew, (Every PHP5\Vista\IIS7 machine I have every worked on does this; 20+ machines) The same error can be achieved back-to-back simply by running any PHP, which in turn will add 1 active application to the DefaultAppPool. This is visible in the IIS7 Manager. You can select the DefaultAppPool and click "Recycle...", wait 3-5 secs (because WerFault.exe kicks in, Windows Error Reporting Service) and you have a "IIS Worker Process has failed" message with the event in the windows event log the way Matt described which says the fault came from c:\windows\system32\ntdll.dll If the PHP dev guys are trying to recreate this issue, you need to be using Latest PHP5/IIS7/ISAPI-Configuration/Vista This has been going on since Vista RC1. Everyone who is not getting this error may not be complaining because the error doesn't seem to do major damage. The closest thing to a resolution I have seen since the release of Vista is to just adjust the timing of the automated recycle cycle. Since the error is only occurring during recycling, they have been scheduling 1 recycle per day, hence 1 crash per day. There are many, many, many, MANY forums and support threads with people having the same problem, they just aren't posting here.

Sara, please take a look, seems like this cryptic piece of code (so
messy) uses wrong length to get the piece of data here..
[2007-10-04 13:24:20] misc at e2007 dot cynergi dot com
I'm tired... 3rd paragraph in the "description" should have read: "The
following code examples where compiled when under Windows the command
... returned:", and the "expected result" string length should be
greater than 127, of course.

Description:
dns_get_record() doesn't return all text from TXT record.
RFC 1035 states that TXT record values can't have "compression", but
can have multiple strings for the same DNS record. Although uncommon,
such long TXT strings actualy exist to make publicly available public
key data for DomainKeys e-mail protocols (used by Yahoo! and Gmail).
The following code examples where compiled when under Windows, the
command "nslookup -type=TXT bravo._domainkey.yahoogroups.co.uk"
returned:
(...)
Non-authoritative answer:

Description:
PDOStatement::exec() returns int(1) to any successful query.
I have tried it with PDO drivers for postgresql packaged with PHP
version 5.2.5 on Windows XP, and version 5.1.4 on Linux.
The method returns number of affected records on Linux, but returns int(1)
to any successful query on Windows.
PostgreSQL version is 8.2.6 for Win32.

exec('insert into test values( now() )');
$insert2 = $db->exec("insert into test values( now()+interval '1 day'
)");
$update = $db->exec("update test set tm=now() + interval '2 day'");
$select = $db->exec('select * from test');
$delete = $db->exec('delete from test');
}catch(PDOException $e){
echo $e->getMessage();
exit;
}
?>

insert2:
update :
select :
delete :
