Re: [fw-general] Zend Search Lucene: Searching for URLs

2007-04-03 Thread Dave Dash


You bet.

It's ITS/ Indexed Tokenized Stored (like most of my fields).

Here's the query logic:

public function executeSearch()
{
$query = strtolower($this->getRequestParameter('q'));

$hits = array();

if ($query)
{   

$index =
Zend_Search_Lucene::open(sfConfig::get('app_search_card_index_file'));


Zend_Search_Lucene_Analysis_Analyzer::setDefault(new
Zend_Search_Lucene_Analysis_Analyzer_Common_Utf8Num());

$hits = $index->find($query);
}

An example query in my form would be 

hawaiimoves.com

or

url:hawaiimoves.com

The same queries work fine in Luke.  Also other fields seem to work just
fine.

Thanks!

Re: [fw-general] Zend_Parser

2007-04-03 Thread Kevin McArthur


the new api looks like this..

$image = Zend_Pdf_Image::imageWithPath($pathtofile);

It will use the new parsers and the filename (should be mime detecting) to 
determine what Zend_Pdf_FileParser_Image derived object to use on a 
Zend_Pdf_FileParserDataSource_File resource.. It was done this way such that 
an imageFromBinaryString() or imageFromUrl() static methods could be added 
and not care if the data is in a file or a stream or whatever.


The other two old parsers jpeg + tiff require that they know the filename 
(jpeg because it passes it off to gd) and the tiff because I haven't gotten 
around to rewriting the parser to work with the new architecture.


It would likely be harder to get the old stuff to fit in the new 
architecture than to just rewrite the file parsers to the new format (though 
jpeg might be hard because no one actually ever wrote a proper jpeg 
parser)


In the patch i passed along, the new classes of importance are..

/Pdf/Resource/Image/PNG.php (note uppercase)
class Zend_Pdf_Resource_Image_PNG extends Zend_Pdf_Resource_Image
   public function __construct(Zend_Pdf_FileParser_Image_PNG $imageParser)
...

/Pdf/Image.php
abstract class Zend_Pdf_Image
   public static function imageWithPath($filePath)
   protected static function _extractJpegImage($dataSource)
   protected static function _extractPngImage($dataSource)
   protected static function _extractTiffImage($dataSource)

/Pdf/FileParser.php
abstract class Zend_Pdf_FileParser
   abstract public function screen();
   abstract public function parse();
   public function __construct(Zend_Pdf_FileParserDataSource $dataSource)

/Pdf/FileParserDataSource/File.php
/Pdf/FileParserDataSource/String.php
//Todo: url.php, stream.php

class Zend_Pdf_FileParserDataSource_File extends 
Zend_Pdf_FileParserDataSource

   public function __construct($filePath)
class Zend_Pdf_FileParserDataSource_String extends 
Zend_Pdf_FileParserDataSource

   public function __construct($string)


/Pdf/FileParser/Image.php
abstract class Zend_Pdf_FileParser_Image extends Zend_Pdf_FileParser
   public function __construct(Zend_Pdf_FileParserDataSource $dataSource)


/Pdf/FileParser/Image/PNG.php
class Zend_Pdf_FileParser_Image_PNG extends Zend_Pdf_FileParser_Image

   public function parse()
   public function getWidth()
   public function getHeight()
   public function getBitDepth()
   etc.


What needs to be done is

/Pdf/FileParser/Image/Jpeg.php
/Pdf/FileParser/Image/Tiff.php
/Pdf/Resource/Image/Jpeg.php
/Pdf/Resource/Image/Tiff.php

Following the png example already created.

The old Resource files must die.

There should also probably be a Zend_Pdf_FileParser_Image_Interface created 
to handle the common methods created in Zend_Pdf_FileParser_Image_PNG


Its a fairly labourous peice of work, but isn't highly technical (except 
maybe the jpeg parser to factor out gd)


If this gets translated to a common api, everything except for the Resource* 
classes would get shifted out of /Pdf/ entirely


Meaning, Zend_Pdf_FileParser* would need to be relocated and re-mapped 
elsewhere -- as for PDF using the new parsers, its fairly trivial because 
they operate over a standard api...calling things like $this->_width 
= $imageParser->getWidth(); and such. The new resource classes dont parse 
any binary data, but instead only handle the imagedata->pdf translation of 
the image.


Hope that helps..

Can you explain what you've updated in ZPDF lately, my patch is out 
of date. Seems like its been reorganized and the parsers moved to 
Pdf/Resource/Image but they havnt been modernized at the same time.


Here's my patch so far (just png support) this is the current status 
of ZF-11 http://framework.zend.com/issues/browse/ZF-11


Maybe we should end ZF-11 and start thinking about a generalized file 
parser, and then integrating that into pdf.


I hope the patch below will apply cleanly to a recent version but it 
was written long ago. (Should be applied in /Zend/Library/Pdf/)

Re: [fw-general] search engine

2007-04-03 Thread Alexander Veremyev

Performance of what? ;)

To talk about increasing (or decreasing) performance we should have 
things to compare.

Relational database doesn't give full-text search capabilities.

Using LIKE SQL clause can't give some features (like sorting result set 
by relevance) and needs full data scan (so Zend_Search_Lucene is much 
more faster, except some trivial cases).

Some RDBMS offer full-text search extensions or you can use any special 
product for full-text searching.
But we should compare concrete products. (We don't have any comparisons 
with other products now, only some comparisons with Java Lucene)

It's clear they have all chances to be faster, but you have to choose 
system according to simplicity of system installation and configuration, 
performance, supported features (including supported query language) and 
so on.

I can say that Zend_Search_Lucene is a good choice.

With best regards,
   Alexander Veremyev.

Hi José,

There are two possibilities:
1) As it already was mentioned by Joshua, it's possible to use your
database capabilities for full-text searching or use any other tool.

2) Use Zend_Search_Lucene as full-text index in addition to you
relational database.
It's not data duplication. You can store only index information without
storing field values.
Data from your relational database can be indexed absolutely the same
way you can index filesystem data.

Just use 'SELECT * ...' instead of fread() :)

Alexander Veremyev.

[fw-general] Zend Search Lucene: Searching for URLs

So I've indexed a document that has a field called "url" filled with URLs
(e.g. http://reviewsby.us/, http://spindrop.us/, http://www.nabble.com, etc,

I can find these in Luke just fine by searching for the url (without the
http:// in fact)

But in my ZSL 0.9.1 app I get nothing.  If I search for http or https I do

Luke was using the default analyzer (Keyword) and ZSL was using UTF8_Num,

2007-04-03 Thread Kevin McArthur


Matt,

So long as it works i'm very flexible. However, do take a look at the plans 
for improving the memory handling of zend pdf streams. Loading data from a 
parser, then into like 5 or 6 classes is going to suck performance (and 
memory) wise when using these on larger binary files.


The memory consumption used by parser/writer pairs should be close to the 
max-size of the file and not 5 or 6x times filesize. So keep that in mind.


Other than that, whatever works.

Ah, streams--that dark, deserted, slightly scary corner of the PHP world.

Zend_Stream_Reader seems to be a better fit, name-wise, when you look at

   Zend_Pdf_Reader extends Zend_Stream_File_Reader

   Zend_Pdf_Writer extends Zend_Stream_File_Writer (Zend_Pdf becomes the

   My_Image_Gif_Writer extends Zend_Stream_File_Writer

Streams could then be combined in any number of ways to make reading and

promoting the use of streams in PHP.

Well, I was thinking:

Zend_String_Parser extends Zend_Parser_Abstract
Zend_String implements Zend_Parser_DataSource_Interface
Zend_String_Multibyte extends Zend_String

The actual read methods are implemented by the data source objects, so one
parser would work for both.  Zend_String_Parser and Zend_String would be
easy (Willy's already done much of the work), but Zend_String_Multibyte
would be a job in and of itself, if it wasn't stipulated to be dependent
on mbstring and/or iconv.

I'm not sure how it should work in cases where you are parsing a binary
file and come across certain bytes that are, for instance, Unicode.  I
guess something like

$string = new Zend_String_Multibyte($bytes, 'UTF-16LE');

isn't too awkward.

Yeah, that's probably a good idea.  Implementation specifics can be
documented.

No, thinking about stuff like this now is great, so we don't have to

Re: [fw-general] search friendly

2007-04-03 Thread José de Menezes Soares Neto

Very nice answers, but I am getting a little problem cause I am newbie in ZF.

I will try your suggestion for urls like

http://localhost/project/search/test

But I dont know where in the project I have to put the code above (index.php? 
SearchController.php?):

$router = $front->getRouter();
$searchRoute = new Zend_Controller_Router_Route_Static(
'search/:query',
array('controller' => 'search', 'action' => 'index')
);
$router->addRoute('search', $searchRoute);

So, I tried to put at index.php and I got this error:

Fatal error: Uncaught exception 'Zend_Controller_Exception' with message 
'SearchController::okAction() does not exist and was not trapped in __call()' 
in D:\www\projeto\lib\Zend\Controller\Action.php:474 Stack trace: #0 [internal

I don´t know what to do exactly... My index.php is attached...

Thanks very much again

  So either create a new route for this:

  $router = $front->getRouter();
  $searchRoute = new Zend_Controller_Router_Route_Static(
  'search',
  array('controller' => 'index', 'action' => 'search')

  OR create a new controller, SearchController, with indexAction() that
  performs the search.

  Easy: create a custom route:

  $router = $front->getRouter();
  $searchRoute = new Zend_Controller_Router_Route_Static(
  'search/:query',
  array('controller' => 'search', 'action' => 'index')
  );
  $router->addRoute('search', $searchRoute);

  > The problem for this last url is the form submission, cause it constructs

  You're not going to be able to get a form submission to append to the
  url path unless you use javascript; forms either populate the query
  string ($_GET in PHP) or POST content ($_POST in PHP). I'd suggest *not*
  using javascript, and instead doing something like:

  
  
  
  

  This will work with either of the routes listed above, and will work

Hi Tomek,

I proposed adding an option to disable the check for save_path

If you set save_path to anything writable the exception will not occur.  
Setting a save_path has no effect, if you are not using the default 
files-based save handler.

The request object (and by extension, the accessors to it in the action
controller) does not have array awareness. You can either access it
using $_POST, or do a two-step access like the following:

$name = $this->_getParam('name');
$salutation = $name['salutation'];

The request object is mainly to facilitate mapping requests to
module/controller/action names and request parameters not normally
available via PHP (i.e., not available via $_GET and $_POST, such as
URL path segments). The HTTP request object has hooks into $_GET and
$_POST simply because it may grab some of the above information from
those arrays if not found in the path.

Currently, because the request object has no filtering or validation,
the main use for it in your scripts should be to access URL path
information as set by the router (e.g., if matching /blog/:id, you can
access 'id' as $this->_getParam('id')).

Hi

I am using

$this->_getParam('name')

which is an array from a form post

It print out:

//POST array(3) {
//  ["salutation"] => string(3) "Mr."
//  ["first_name"] => string(10) "Ian Warner"
//  ["last_name"] => string(10) "Ian Warner"
//}

How do I extract just the salutation from this?

Dead easy problem just cant think at the mo.

I use

Zend_Debug::dump($this->_getAllParams(), 'POST', false);
Zend_Debug::dump($this->_getParam('name'), 'POST', true);

is using a _method even the best thing to do here, is it better than 
using the $_POST var

Re: [fw-general] Re: Forwarding - Redirecting

2007-04-03 Thread Gavin Vess


Hi Stephan,

I have not seen any specific problems mentioned with the functionality 
of _forward() and _redirect().  However, I have seen open source 
applications that ambiguously used the word "forward" to perform HTTP 
redirection.  Words used ambiguously can be confusing.  Maybe the names 
are not ideal?


_forward()  =  internally forward to an action controller (e.g. 
module/controller/action)


_redirect() = external HTTP redirect (e.g. any URL via 301/302/303 
http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html)


They do different things:

Re: [fw-general] Re: Forwarding - Redirecting

2007-04-03 Thread Nico Edtinger

Won't work if you have a different URI design. I.e. we use http:// 
example.org/index.php/contact.add.import instead of http:// 
example.org/index.php/contact/add/import or http://example.org/ 
index.php/contact_add/import or ... as controller (+ module) name.


If the default Action class is changed to have the same parameters in  
_redirect() as in _forward(), it won't be easy to change that in your  
own class extending the Action class. But it's easy to create an  
Action class, that has the same parameters with the current Action  
class:


class Example_Controller_Action {
	function _redirect($action, $controller = null, $module = null,  
array $options = null) {

if ($controller === null) {
$controller = 
$this->getRequest()->getControllerName();
}
$url = $controller . '/' . $action;
if ($module !== null) {
$url = $module . '/' . $url;
}
parent::_redirect($url, $options);
}
}

The factory is going, but the other parsers arent ready so changing the api 
right now would break jpeg/tiff support and leave only png.


I assume matt's GIF parser can extract the bitmap data from the gif, which 
should then be embeddable in the doc (similar how i had to parse png data)

Hi Kevin,

GIF support would be good feature. The difficulty is that GIF is not 
supported by PDF as internal format. So it needs a little bit more 
processing.



There was no any activities in Zend_Pdf for some time. So your patch could 
be applied to current SVN version. (I have some strange problems with 
applying this patch with 'patch' utility, but I checked it manually).



I agree ZF-11 can be postponed up to generalized parser support.

The important thing is to fix user API.
So if we are planing to use something else than 
'Zend_Pdf_ImageFactory::factory()', it would be good to add it now.

Even if it works only as wrapper to current implementation.


With best regards,
   Alexander Veremyev.

Can you explain what you've updated in ZPDF lately, my patch is out of 
date. Seems like its been reorganized and the parsers moved to 
Pdf/Resource/Image but they havnt been modernized at the same time.


Here's my patch so far (just png support) this is the current status of 
ZF-11 http://framework.zend.com/issues/browse/ZF-11


Maybe we should end ZF-11 and start thinking about a generalized file 
parser, and then integrating that into pdf.


I hope the patch below will apply cleanly to a recent version but it was 
written long ago. (Should be applied in /Zend/Library/Pdf/)

Hi!

where is not possible to change mysql port using mysqli adapter.

i've changed Zend_Db_Adapter_Mysqli // function _connect() to this:

protected function _connect()

[fw-general] Very basic question : how to download a file ?

2007-04-03 Thread fred wolf


Hi Zenders,

this is a very basic thing, but I can't make it working out. How can I
download a pdf file for example ? 

I tried to use Zend_Http and set an header with content type
application/pdf, then I got the content file then push it in the
Zend_Http_Response, but It doesn't work.

I'm stuck on planet Zend and  I need some help to get down with my pdf
file...

regards,

fred

I'm no expert by any stretch of the imagination so best wait for a real

That should get the URL's looking more how you want them.

Re: [fw-general] zend_session question

2007-04-03 Thread Raphael Stolt


Have you checked the session.save_path in your php.ini. I ran in the same
problem when updating from ZF 0.8 to 0.9.1, because in my php.ini it wasn't
set and so also not writeable. Setting the path would also switch to the use
of file-based session storage and retrieval.

Hope this is a starting point.

Hi José,

There are two possibilities:
1) As it already was mentioned by Joshua, it's possible to use your 
database capabilities for full-text searching or use any other tool.

2) Use Zend_Search_Lucene as full-text index in addition to you 
relational database.
It's not data duplication. You can store only index information without 
storing field values.
Data from your relational database can be indexed absolutely the same 
way you can index filesystem data.

Just use 'SELECT * ...' instead of fread() :)


With best regards,
Alexander Veremyev.

Re: [fw-general] Zend_Parser

2007-04-03 Thread Alexander Veremyev


Hi Kevin,

GIF support would be good feature. The difficulty is that GIF is not 
supported by PDF as internal format. So it needs a little bit more 
processing.



There was no any activities in Zend_Pdf for some time. So your patch 
could be applied to current SVN version. (I have some strange problems 
with applying this patch with 'patch' utility, but I checked it manually).



I agree ZF-11 can be postponed up to generalized parser support.

The important thing is to fix user API.
So if we are planing to use something else than 
'Zend_Pdf_ImageFactory::factory()', it would be good to add it now.

Even if it works only as wrapper to current implementation.


With best regards,
   Alexander Veremyev.

Kevin McArthur wrote:

Matthew,


Feel like interfacing that with zend_pdf?

We have JPEG/PNG/TIFF supprt though only PNG has been translated to the 
new parser format. Gif support would be cool.



Alex


Can you explain what you've updated in ZPDF lately, my patch is out of 
date. Seems like its been reorganized and the parsers moved to 
Pdf/Resource/Image but they havnt been modernized at the same time.


Here's my patch so far (just png support) this is the current status of 
ZF-11 http://framework.zend.com/issues/browse/ZF-11


Maybe we should end ZF-11 and start thinking about a generalized file 
parser, and then integrating that into pdf.


I hope the patch below will apply cleanly to a recent version but it was 
written long ago. (Should be applied in /Zend/Library/Pdf/)

For say, Zend_String, the interfaces and abstracts are around what one would 
expect. Main difference though which might cloud the connection is that a 
string can contain multi-byte characters so the method names referring to the 
"byte" wouldn't be completely suitable. You can imagine the String classes also 
needing a wrapper to allow for mbstring functions to replace use of substr() 
and other such non-multibyte friendly functions where required (likely a user 
option since mbstring support varies across those troublesome shared hosts).

Would it be possible to generalise the method naming from readByte, skipByte, 
etc., to a simple read(), skip() style? Similarly Zend_File shouldn't be 
specifically for binary files IMO. Strings can be either a PHP string type, or 
a file resource (from fopen() for example). Distinction needs to be made 
between a binary or plain text file in the hierarchy since both types are not 
truly interchangeable without a little abstraction of the read methods.

Sorry if I'm poking at this with a stick ;). I know the immediate need is for 
binary parsing and Zend_String or whatever is down the line a ways even in 
terms of a Proposal.

Subject: Re: [fw-general] Zend_Parser

This weekend I wrote a GIF parser, and refactored it a bit to use these
classes (I do have a life--I did other things, too!).  I've renamed some
things and added some things (like setByteOrder() and BYTE_ORDER_MACHINE)
and spent a couple hours writing an invisible buffering mechanism before
determining that it actually made performance worse.  :-D

Currently, and this is by no means finalized, but this is the structure:

Zend_Parser_Interface
Zend_Parser_DataSource_Interface
Zend_File implements Zend_Parser_DataSource_Interface
Zend_File_Parser_Abstract implements Zend_Parser_Interface
My_Image_Gif extends Zend_File
My_Image_Gif_Parser extends Zend_File_Parser_Abstract

Theoretically, if there were something like Zend_String, it could
implement Zend_Parser_DataSource_Interface and Zend_String_Parser could
implement Zend_Parser_Interface.

If you have suggestions on a better structure, I'd like to hear your
thoughts.
