Re: [PHP-DEV] Maintainer of SNMP module?
HI, This is the same as you have send to the net-snmp-users mailinglist, right?? If not let me know. Harrie On Thursday, December 26, 2002, at 09:06 PM, Johann Hanne wrote: Hi, is somebody actually maintaining the SNMP module? I'm currently using PHP 4.2.3 and I have two major problems which make the SNMP functions unusable for me: - When using snmpwalkoid() the array keys are the OIDs. But if the OID is lying under certain subtrees (e.g. mib-2, experimental, private), all the OID bits leading to that path are dropped (i.e. the OID is shortened). Furthermore known OID numbers are replaced with their textual representation, which makes the array keys dependent on the locally existing MIBs. All this makes it impossible to reliably parse the returned OIDs! A PHP function which calls ds_toggle_boolean(DS_LIBRARY_ID, DS_LIB_PRINT_NUMERIC_OIDS); and ds_toggle_boolean(DS_LIBRARY_ID, DS_LIB_PRINT_FULL_OID); to turn these features off is required. And IMHO this should be the default behaviour. - Returned OID values are read via the sprint_value() SNMP API function. This preparses the values and results in strings like Timeticks: ..., Hex: It is extremely hard (read: impossible) to reliably parse these values for further processing. This behaviour could also be turned off with ds_toggle_boolean() calls, but it's even better to do the parsing in a special function. This way, even the type of the value could be returned optionally. Two other things in the related PHP source code might be regarded as... ermmm... questionable: - sprint_value() and sprint_objid() are used. It seems to me that these functions don't do any overflow checking? And they are not documented, thus probably obsolete (sprint_variable() is documented as obsolete in the mib_api man page). - Is it really wise to use ONE function for ALL SNMP operations (get, set, walk)? The code is hard to read and confusing. IMHO the function should at least be splitted up into a single-OID-function (set, get) and a multiple-OIDs-function (walk). Comments?

[PHP-DEV] ext_skel
Hi,
Someone seems to have changed ext_skel to create the ZEND_FETCH_RESOURCE()
call to be inside an if() statement to check the resource is non-zero, i.e.:
if (myresource) {
ZEND_FETCH_RESOURCE();
}
What is the reason this was added? The resource mechanism checks for this
automatically and handles relevant errors in a consistent way. I think this
if() should be removed.
Also does anyone object to ZEND_FETCH_RESOURCE() being commented. I think
it's beneficial for newly generated extensions to be able to compile right
away so that ppl can see that their setup, buildconf, config.m4 and so on
is OK for development.

[PHP-DEV] string functions
While converting the functions inside string.c to the new parameter parsing API and doing some general cleanup, I've come across an interesting 'feature'. Three string functions: stristr(), strstr() and strpos() have peculiar way of handling non string values passed as 'needle'. Instead of converting the needle to a string they instead convert it to an integer and search for a character equivalent to that integer. This behavior causes a problem such as strstr(abc123, 1) returning false rather then returning 123 as one may expect. Because this behavior is not documented, I believe we could safely change it back to the behavior listed in the manual and the one defined in the function's prototype. The con of this approach is that it may break scripts that really on the undocumented behavior, therefor I propose that this change would only go into the 4.4/5.0 branch at which point people will expect small behavioral changes.

[PHP-DEV] Generic expressions interpolation in strings
I already opened a bug (#21433) about this Feature Request, but I
realized it is better to discuss here about it.
I'm relatively new to PHP. Previously I used to program a lot in Perl.
What I really lack in PHP is Perl's ability to interpolate any
expression inside a string.
For example:
Perl: Next value is @{[ $value + 1 ]}!
PHP: Next value is . $value + 1 . !
In this simple case it's not a great problem, but it becomes more
awkward when using the heredoc operator. In this cases I'm often forced
to use temporary variables:
$tempvar = $value + 1;
print END
Here it is the next value
$tempvar
Other text...
END;
I propose to extend the Variable Parsing syntax to evaluate ANY
expression instead of variables only.
I propose the following syntax:
print END
Here it is the next value
{$= $value + 1 }
Other text...
END;
Using {= would be more readable but it would cause too many backward
compatibility problems...
What do you think of this?
Thanks.

[PHP-DEV] CLI behavior with -q switch
Several production sytems I manage have a bunch of php scripts, that were called with php -q using the CGI interface. The problem is that the -q switch is still in the CLI for backward compatibility, but it breaks scripts because it does not change directories. I would strongly suggest that the -q switch would imply changing the working directory to that of the script, unless overriden by -C. That way, both php -q and php -C -q (as used in PEAR) would give the same results with both CGI and CLI. What do you think?

Id so your above solution is a bad idea and i hope CLI will be... I'm CC'ing the maintainers of PHP for most distributions of Linux, so we can all be in sync. For those that don't know the issue, I'll resume it by saying that with PHP 4.3, there is a new CLI (command-line interface) that complements the CGI interface. The problem is, both files are named php. Here is the solution that I have been experimenting over the past few days, and that will be implemented in Mandrake Cooker (and soon 9.1): - There will be two RPMS: php-cli and php-cgi. - Both packages will provide php - Using the update-alternatives, each package will contain /usr/bin/php as a symlink to the respective binary. This lets us give a priority to which binary is called for a given symlink. php-cli will be given priority 20 (higher), php-cgi will be given priority 10 (lower) - If only one package is installed, /usr/bin/php will link to the right executable. - By default, php-cgi will be installed, in order to maintain backwards compatibility. - Users will be able to install the CLI using rpm -i php-cli - If both packages are installed, php-cli will be called since it's higher priority. - All packages that specifically require the command-line interface (there is none for the moment, but there will be in the future), will explicitely require php-cli. This setup means that we don't break the configuration of people that already have the php CGI interface, while, with one simple command, the new PHP command-line enthusiasts will be able to have their cake. This goes with the PHP source approach: By default, configure/make/make install compiles the CGI interface, and then you have to make install-cli to get the CLI. We just replace the make install-cli by urpmi/apt-get php-cli. Comments/Questions/Suggestions welcome.
