RE: [fw-general] Database profiles for reading/writing with Zend_Db
Maybe i have a easy suggestion:
1) Extend Zend_Db_Table and use the Slaves Database as default adapter.
2) overwrite the insert, update and delete functions and use the Master
adapter
Something like:
Class My_Db_Table extends Zend_Db_Table
{
(...)
Public function insert($data)
{
$this-setDefaultAdapter(--Master Db Adapter--);
return parent::insert($data);
}
(...)
}
And extend all table classes from My_Db_Table

[fw-general] ZF caching output. Howto disable this so can chunk serve file.
Hi, I am trying to chunk serve file using fopen,fread,fseek etc. Problem I think I am having is that ZF is caching the output...and I get out of memory instead of using constant memory for no matter how large file I serve for download. Using MVC part have action for this download have disabled renderer and layout. Please let me know how can disable caching of page..I am pretty sure it occurs.
Re: [fw-general] ZF caching output. Howto disable this so can chunk serve file.
I see that ('disableOutputBuffering',true) on frontcontroller fixed this
issue.
But not sure if can disable this per action. I guess not..as it's done
at dispatch. Controller plugin doesn't help either.

You *can* control it from a controller plugin, but you have to go
directly to the dispatcher to do it:
$front = Zend_Controller_Front::getInstance();
$dispatcher = $front-getDispatcher();
$dispatcher-setParam('disableOutputBuffering', true);

Re: [fw-general] How do I factor out tasks common to every action controller?
-- Steven Szymczak [EMAIL PROTECTED] wrote
(on Wednesday, 15 October 2008, 11:09 PM +0100):
Every one of my action controllers has an init() function that pulls a
config object from the registry and uses it to set some paths used
throughout the site (e.g.):
public function init() {
$view_cfg = Zend_Registry::get('SITE_CFG');
$this-view-__set('pubImages', $view_cfg-dirs-images);
$this-view-__set('jsDir', $view_cfg-dirs-js);
$this-view-__set('cssDir', $view_cfg-dirs-css);
}
How can factor out this functionality without resorting to a parent
class for all my action controllers? I seem to recall a similar post to
the list, several months ago, that suggested utilizing a helper
somehow...
Create an action helper that implements functionality in preDispatch(),
and register it with the helper broker in your bootstrap. It might look
like this:
class My_CommonViewVariables extends Zend_Controller_Action_Helper_Abstract
{
public function preDispatch()
{
$view = $this-getActionController()-view;
$viewCfg = Zend_Registry::get('SITE_CFG')-dirs;
$view-assign(array(
'pubImages' = $viewCfg-images,
'jsDir' = $viewCfg-js,
'cssDir'= $viewCfg-css,
));
}
}
And then, in your bootstrap:
Zend_Controller_Action_HelperBroker::addHelper(new My_CommonViewVariables);
BTW, don't call magic methods directly; it's a bad idea. Your original
example would have been better written using $this-view-cssDir =
$view_cfg-dirs-css;, or, if you really want to use method calls, the
assign() method (which takes either two arguments, like __set(), or an
array of key/value pairs, as in the helper I detail above).

));
I want to know how to add a table row with headings using decorators.
Example output needed:
trthhead1/ththhead2/ththhead3/th/tr
I want this row to appear on top of other rows in the table.

that cell.

Specifically, you'll want to do something more like this for a

public function insert(array $data)
{
if (self::$_writeAdapter === null) {
throw new My_Db_Table_Exception('No write adapter specified');
}
$currentAdapter = $this-getAdapter();
$writeAdapter = self::$_writeAdapter;
$this-_setAdapter($writeAdapter);
$result = parent::insert($data);
$this-_setAdapter($currentAdapter);
return $result;
}
You'll also want to have setReadAdapter() and setWriteAdapter() methods
along with the insert(), update(), and delete().

Re: [fw-general] Routes _Get Parameters
No. Static routes are exactly that.; you cannot use parameters with them.
You'll need just a standard route:

'show/:id',
array(
'controller' = 'show',
'action' = 'display',
// You could set a default value for the :id parameter here
)
);
$router-addRoute('user', $route);|

[fw-general] XMLRPC Server Performance
Hey guys,
I'm planning to use Zend_Xmlrpc_Server for my API. I have it working, and so
far, it's been super. It's made everything incredibly easy to do. My only
issue so far has been performance, and a weird quirk that I've found through
a bit of testing. Based on a previous issue (
http://framework.zend.com/issues/browse/ZF-3280), I'm not using
Zend_XmlRpc_Server_Cache, and I am using the APC opcode cache (which has
driven down memory usage considerably, but speed still remains an issue).
This kind of leads me down the path of guessing the CPU usage is the main
bottleneck. So, I made my XmlrpcController like so (with other setup
omitted, obv.):
public function indexAction() {
$overall_start = microtime(true);
$start = microtime(true);
$this-setClasses(); // sets about 10 classes into the server, for
about 150 (?) functions total
$elapsed = microtime(true) - $start;
API_Logger::debug(Got server in [$elapsed] seconds);
$start = microtime(true);
$ret = $this-server-handle();
$elapsed = microtime(true) - $start;
API_Logger::debug(Handled response in [$elapsed] seconds);
$overall_elapsed = microtime(true) - $overall_start;
API_Logger::debug(Overall request time [$overall_elapsed]);
API_Logger::debug();
die($ret);
}
Now, the interesting thing that I've discovered is that one client request
at a time seems to respond in a decent amount of time. My output looks like
so:
2008-10-16 22:38:36 INFO (6): [6313] Got server in [0.25338101387] seconds
2008-10-16 22:38:37 INFO (6): [6313] Handled response in [0.103404998779]
seconds
2008-10-16 22:38:37 INFO (6): [6313] Overall request time [0.360664129257]
2008-10-16 22:38:37 INFO (6): [6313]
However, when I make three requests to the same method at the same instant
(using firefox refresh all tabs, ha), each request is quite a bit slower:
2008-10-16 22:41:53 INFO (6): [6724] Got server in [0.860436916351] seconds
2008-10-16 22:41:53 INFO (6): [6465] Got server in [0.796639919281] seconds
2008-10-16 22:41:53 INFO (6): [6736] Got server in [0.816692113876] seconds
2008-10-16 22:41:53 INFO (6): [6465] Handled response in [0.284796953201]

2008-10-16 22:41:53 INFO (6): [6736]
As I increase the number of simultaneous requests, the difference is more
and more drastic. As the requests to the API server start to pick up, the
box is brought to its knees pretty quickly. The CPU usage on the box is
pegged, while memory isn't that much of a problem. More hardware would help,
but not forever, if I want the API server cluster to start getting decent
3rd party usage.
So, my question is, is there something I can do? Can I put the server on a
ramdisk? Can I use memcached to cache $this-server in my example above? I'm
running this out of Apache, and would a more drastic move of trying lighttpd
and fastcgi be a path to explore (b/c php stays in memory)?
Failing all that, this is a plea for help. :)
thanks in advance,
