torrent-rw's Issues

Another PHP 5.4.0 Warning

Hey,

Getting a lot of these in my log:

Accessing static property Torrent::$errors as non static in torrent_inc.php on line 113

line 113 is:

$this->{$key} = $value;

extraire la "key" d'un torrent

Bonjour,

Est-il possible d'extraire l'attribut key à l'aide de cette librairie?
En effet de nombreux .torrent embarque une clef unique pour pouvoir identifier le client, ce serait très utile de pouvoir extraire cette clef.

send() gives "Invalid torrent file!"

Hi!

First things first; I just love this class! Many thanks!

Now to the problem. When I set the new information about the torrent-file and choose $torrent->send() to download the torrent with the new information, I can't open the file! I only get "Invalid torrent file!". Please help?

Thanks in advance.

Unable to get information from https-link

Hi again! :)

Your function will not get information about a .torrent-file if it's link through https. Example: https://thepiratebay.org/torrent/6369032

Modify torrent doesn't work

Hi there,

I'm not able to modify torrents at all.

require_once 'Torrent.php';

$torrent = new Torrent('test.torrent');

// modify torrent
$torrent->announce('http://alternate-torrent.tracker/announce'); // add a tracker
$torrent->comment('hello world');

This should modify the tracker and comment, but it does not work.
I'm running PHP 5.5, with cURL enabled.

Any ideas?

torrent not working

notworking.zip

Hi
Your class cannot open this file. however it works fine in utorrent.

Could you please check?

Regards

Missing charset ?

There is no charset specified (like charset=utf-8) :
https://github.com/adriengibrat/torrent-rw/blob/master/Torrent.php#L362

Intentional ?

Can't get info of particular torrent

Regardless of his content, I can't get the content of this torrent, I guess there is an error in the bencoding function.

Problem with some torrents

Hi,
I have a problem with some torrents - I received error "Non-digit characters in integer" on line 535
If commented lines 530 and 534 - all works correct (in other words if system see i-1e it throws exception)

UDP Tracker Scrape

Hi,

This is more of a feature request. Could you please consider making it possible to scrape a UDP tracker for numbers, as a lot of trackers seem to be switching to UDP only model (openbittorrent being the biggest one). Since you now use CURL this should be no problem.

Cheers.

Unable to retrive contents of torrent containing many files

Hello,

First of all, Thank You for this amazing Library/Package!

I am facing some issue getting the list of torrents containing almost 40-50 files. Let's say I have a torrent file containing more than 50 files in this manner

• Directory - 1
  • -- File 1
• Directory - 2
  • -- File 2

The content() function return an empty Array in this case.

Can you please look into it once?

Thanks,

Corrupted chars in files

Try to parse these torrents to check it (look like utf-8 corrupted).

Activer le DHT

Salut,

Je crois que la fonctionnalité d'activer le DHT d'un torrent n'est pas disponible me semble-t-il.

Possible de l'ajouter ?

Merci

Modify comment and creator

Hi,

This is really great tool. I just started using this tool.

I need to modify only comment and create by from .torrent file. Can you help me with that?

Large torrent size.

I tried using this class with some that has 4mb size. It takes forever.

Maximum execution time of exceeded when reading torrent file

Hi
I'm getting the errors
PHP Fatal error: Maximum execution time of 55 seconds exceeded in /home/mojtaba/.rapidpich/lib/Torrent.class.php on line 531
it's not always the same lines however I get repeated error around same lines. I also don't know where the 55seconds come from as I'm running the script in cli mode.
The lines are mostly 539 - 543 but sometimes 520,511,476
(It's the same torrent but everytime it terminates at different line
The script does hog one CPU core at 100%.

error.zip

The torrents are rather large so this might be the same problem as
#38
but since the OP of that issue didn't provide more details I opened a new issue.

Warning: array_intersect_assoc(): at least 2 parameters are required, 1 given in ....../Torrent.php on line 710

Only variables should be passed by reference

Salut,

Tiens une nouvelle erreur :

Strict Standards: Only variables should be passed by reference in /home/admin/domains/.com/public_html/cfg/torrent.php on line 334

Il me semble que c'est à cause de PHP 5.4 donc ligne 334 :

$stats = self::decode_data( curl_multi_getcontent( $done['handle'] ) );

en

$stats = curl_multi_getcontent( $done['handle'] );
$stats = self::decode_data( $stats );

;)

Ajouter la date de création du torrent

Bonjour Adrien,

Je me doute que tu ne maintiens plus trop cette class, mais peux-tu, à l'occasion, ajouter les informations concernant la date de création du torrent.

Ca ressemble à :

creation datei1483384502

Cordialement

Encode

Hello thanks for the script:) is there a way we can bencode back to .torrent file from decoded data. Like for example I have metadata stored in mysql and I would like to create torrents from it. Is this possible with this script.

Kind regards

Does not work with torrents created by deluge, py3createtorrent, transmission-create, and buildtorrent...

I don't have access to the server logs of the torrent site where these fail, but they do.

Integratye class Scrapeer to scrape UDP

Hello,

Is it possible to integrate the PHP Scrapeer class to scrape torrents in UDP?

Bonjour,

Est-ce possible d'intégrer la class PHP Scrapeer pour scraper les torrents en UDP ?

https://github.com/medariox/scrapeer

is_torrent function works bad

Hi Adrien,

It's about is_torrent function.
Do you know better way of torrent meta-file format validation?
I downloaded torrent file from http://torrent.ubuntu.com:6969/ , first link. The file has d8:announce at the begin, but mTorrent said the format is invalid, and your Torrent.php library returns hash=NULL.

What do you think?
Btw, thx for great library.

Max.

Some torrents not being accepted

Hi,

It seems the is_torrent code needs some more updating again. The following torrent is valid and accepted by clients, but returns not a torrent error. Hope it can get fixed.

http://rghost.net/52049812

New torrents from certain directory structures are accidentally flattened and files are discarded

When a root directory that contains more than one descendant directory who, themselves, both share a common parent directory but whose parent has no files, the Torrent::files method incorrectly identifies the root directory as one of the descendant directories rather than their shared parent directory.

Specifically, given a directory structure like this:

$ tree
.
└── child-directory
    ├── descendant-dir1
    │   └── file1.txt
    └── descendant-dir2
        └── file2.txt

creating a new torrent from either . or ./child-directory like so:

<?php
require_once 'Torrent-RW/Torrent.php';
$torrent = new Torrent('/path/to/child-directory', 'udp://tracker.publicbt.com:80');
$torrent->save('test.torrent');

will create a torrent file whose info dictionary only lists the contents of descendant-dir2:

$ lstor --raw test.torrent 
{'announce': 'http://tracker.openbt.com/',
 'created by': 'Torrent RW PHP Class - http://github.com/************/**********',
 'creation date': 1421322276,
 'info': {'files': [{'length': 0, 'path': ['file2.txt']}],
          'name': 'descendant-dir2',
          'piece length': 262144,
          'pieces': '<0 piece hashes>'}}
INFO:pyrocore.scripts.lstor.MetafileLister:Total time: 0.047 seconds.

This is unexpected behavior. Instead, both the contents of descendant-dir1 and the contents of descendant-dir2 should have been included, with child-directory (their common root) being correctly identified as the torrent root.

However, if we then add a file inside of child-directory, so that our directory tree looks like this:

$ tree
.
└── child-directory
    ├── descendant-dir1
    │   └── file1.txt
    ├── descendant-dir2
    │   └── file2.txt
    └── fileX.txt

Then the correct root (child-directory) is identified:

MacBookPro:torrent-test meitar$ php ./test.php 
MacBookPro:torrent-test meitar$ lstor --raw test.torrent 
{'announce': 'http://tracker.openbt.com/',
 'created by': 'Torrent RW PHP Class - http://github.com/************/**********',
 'creation date': 1421322693,
 'info': {'files': [{'length': 0, 'path': ['fileX.txt']},
                    {'length': 0, 'path': ['descendant-dir2', 'file2.txt']},
                    {'length': 0, 'path': ['descendant-dir1', 'file1.txt']}],
          'name': 'child-directory',
          'piece length': 262144,
          'pieces': '<0 piece hashes>'}}
INFO:pyrocore.scripts.lstor.MetafileLister:Total time: 0.029 seconds.

Problem with torrents detector

Problem with function "is_torrent" - its not detects torrents without announce urls (somebody of users really lazy)

static public function is_torrent ( $file, $timeout = self::timeout ) {
        return self::file_get_contents( $file, $timeout, 0, 11 ) === 'd8:announce'
            or self::file_get_contents( $file, $timeout, 0, 14 ) === 'd10:created by';
}

P.S. Ofc, it's workaround

Error while reading some torrent file

Hello
When I try to read this torrent file:
https://pirateiro.com/download-t64/download
I get the following error:

PHP Fatal error: Cannot access property started with '\0' in Torrent.class.php on line 113

I temporarily solved the issue by changing the following lines:

        foreach( $meta as $key => $value )
        {
            $key = trim($key);
            $this->{$key} = $value;
        }

but I don't know if I might be breaking something or not!

Problème avec certains torrents

Plop,

Avec certains torrents, par exemple :

http://www.smartorrent.com/?page=torrentinfo&tid=256309

Le décryptage ce fait mal, il trouve un fichier de 14.1 Ko. Et quand je lance sur uTorrent aucun soucis.

Merci :=)

$torrent = new Torrent($torrent_file);
$torrent->send();

Open in Qbittorrent 4.0.4 and http://torrenteditor.com/

returns inaccurate seed and peer count
