There won't be a release done from this branch, so it's not needed to synchronise it. AFAIK it was only added because Sascha (and perhaps others, I forgot) wanted to continue some small development for the PHP 4.x series without screwing with the stable 4.3.x branch.

Re: [PHP-DEV] Re: INI defaults for CLI
Hi Marcus, This patch looks fine to me, but I have the same reservations as you in that I'm not sure if we really need to modify the current behavior. IIRC it was Markus who objected to the way CLI overrode some default ini settings in a way that php.ini entries were ignored. You could still change them with -d command line switch. I'm sort of +0.5 for applying this patch if no other objections surface. If it gets applied we're probably best of commenting out relevant php.ini-dist and php.ini-recommended entries and noting in the commend what are defaults.

Re: [PHP-DEV] php_pgsql.dll problem
php_pgsql.dll does not depend on external libpq.dll (its built in statically). Your problem is most probably in the local install, ie. a stale php4ts.dll somewhere.

[PHP-DEV] Patch for OCI8 link failure (Tru64/AIX) (#22324)
Hi, my older patch for the link problems with OCI8 on Tru64 broke the build on AIX and maybe other systems, so Jani commented it out. Here comes a better patch. Instead of just linking to libocijdbc8/9 if it is available, it tries to find the OCILobIsTemporary function in the normal libclntsh first, and does nothing if it's there. Only if OCILobIsTemporary is not in libclntsh, another check is done to search it in libocijdbc8/9. I tested it on Linux with Oracle 8.1.6, Tru64 with 8.1.6, 8.1.7 and 9.0.1, and made sure that libocijdb8/9 is linked only when necessary. The patch is not yet tested on AIX, though. I'll ask the two people who reported bug #22324 after the patch has been applied (or should I ask them before the patch is applied, and send them the new configure and main/php_config.h.in built here?). Just before posting this, I became aware that at least here (Linux, Oracle 8.1.6), the line AC_DEFINE(HAVE_OCI8_SHARED_MODE,1,[ ]) results in a core dump at startup, if I use --with-oci8=shared. This is a separate problem (#22521), it also happens without my patch. Setting OCI_USE_EMALLOC to 1 in oci8.c doesn't change it. Regards...

This alone pushed nearly-empty-page req/sec pages from about 285 to about 400 on my Windows box. I'll look into fixing the other ones later. Pre-requisites for this optimization to kick in: 1. register_globals being off 2. register_long_arrays (HTTP_*_VARS) being off If you want to benchmark w/ vs. w/o, you can disable the optimization by initializing cb to 0 in php_startup_auto_globals() and jit_initialization to 0 in php_hash_environment(), both in main/php_variables.c.

One could populate them as an overloaded object, and then array accesses would work - I guess. But I would prefer a cleaner mechanism. This would prevent a costly overhead for elements that don't really need to be there, and yield only a slight performance cost when accessing overloaded elements in these arrays. -Sterling -- The computer programmer is a creator of universes for which he alone is responsible.

[PHP-DEV] Re: #22527 [Opn-Bgs]: Modulus returned negative value
This is actually an interesting question. Should we be truncating towards
zero? I'd say yes, but then I tested Perl, Python and Tcl, and they all
say that -27 % 7 is 1 which means they truncate towards negative infinity.
Too late to change at this point in the game, but perhaps it calls for a
modulus() function which leans the other way?

Bug Type: Math related
Operating System: Unix
PHP Version: 4.2.3
New Comment:
Modulus has never been well-defined for negative values in computer
languages. It all comes down to whether the language truncates towards
zero or towards negative infinity. Computers have traditionally
truncated towards zero, whereas mathematicians tend to truncate towards
negative infinity. Some languages like Fortran and Ada actually have
two different modulus operators for this reason. PHP just has one, and
it truncates towards zero as has been the traditional and expected
thing for programming languages to do.
So, given that, let's look at your numbers. Modulus has to satisfy the
relation: (a/b)*b + a%b = a
where a/b is an integer division where our truncation direction comes
in.
(-27/7) * 7 + -27%7 = -27
( -3 ) * 7 + -27%7 = -27
-21 + -27%7 = -27
-27%7 = -27+21
-27%7 = -6
In fact, the ISO standard for the C programming language, in which PHP
is written, defines integer division and modulus operators to perform
truncation towards 0 and not towards negative infinity. We don't
really have a strict language definition for PHP, but if we did, we
would most likely follow the lead of languages like Fortran, C and C++
and specify truncation towards zero to be as consistent as possible
with other languages.

Hi,
I had the following result from a PHP script, as seen from printing
output variables:
-27 % 7 == -6
My understanding of the modulus function is that it returns the
remainder from division, and that the remainder can never be negative.
I believe that is the standard mathematical definition.
So I think what should have been returned is 1 instead of -6.
That is
-27 = 7*(-4) + 1
instead of
-27 = 7*(-3) -6
I got around this by adding the the modulus value if the result was
less than zero. But I think a result of less than zero shouldn't
occur.
Code snippet that ran into this:
$T5 = $D + $T1 + $Y + $T2 + $T3 - $T4;
$weekday = $T5 % 7;
Added code to handle this:
if ($weekday 0) {
$weekday += 7; // -27 % 7 = -6 case
}
Specific problem case:
$T5 = 3 + 2 + 3 + 5 + 0 - 40; // -27
$weekday = %T5 % 7; // -27 % 7 = -6
Thanks!
