coding questions

Hi,

First of all, i 'd like to thank you Gregor and Arne! Gongrats guys!

I want your help in order to grasp phex development quicker and why not contributing some code. I searched the forum but i didn't find something useful. So i have some newbie questions:
1) Can i run phex without gui? I didn't find such a setting.
2) If i know a file's name with its id and i know the ip of a servent that shares that file, which java class(es) should i use to download that file from that servent?
3) Does phex support browse-host extension?

Thanks a lot,
Geroge.

Hi codditor,

Firstoff: Welcome to the Phex forums!

From your questions I can only answer 1 and 3:

1) Yes: http://www.phex.org/wiki/index.php/A...headless.29.3F

Code:

java -Xmx512m -Djava.awt.headless=true -jar phex.jar

It still requires an X-server though, since Java depends on some of its functions.

Also you can't control it from there: You need to start it in GUI mode to setup your share downloads and preferences, then you can quit and restart in headless mode (we don't yet have commandline control).

3) Yes - just look in the search tab. When you click "new search" you have the option of selecting "browse host".

For 2 I sadly can't help directly.

I know that you need to initiate the download with the address of the host as first source - maybe that helps you.

What I did for subscriptions (with much help from Gregor) was this:

Code:

public void createDownload( String uriStr ) throws URIException
    {
        if (uriStr.length() == 0)
        {
            return;
        }
        URI uri = new URI( uriStr, true );
        Servent.getInstance().getDownloadService().addFileToDownload( uri, true );
    }

-> https://phex.svn.sourceforge.net/svn...ownloader.java

With phex.servent.Servent and org.apache.commons.httpclient.URI;

The URI was a magnet with a first source.

But I assume addFileToDownload() has a more convenient way to add a download with source (which doesn't require creating and then parsing an URI for the sole reason of passing a source - subscriptions were magnet uris, so this way was useful back then).

Hi Gregor! Is there a class in phex with which i can download a specific file (knowing its name and its local index) directly from a servent (knowing its ip)?

You should do downloads using SHA1. Using of the file index is kind of deprecated and might stop working sooner or later.

To do downloads by SHA1 use:

Code:

URI uri = new URI( "http://<ip>:<port>/uri-res/N2R?urn:sha1:<SHA1>", true );
Servent.getInstance().getDownloadService().addFileToDownload( uri, true );

Where do i find the SHA1 hash of servent's file?

GregorK · #8 (**permalink**) May 30th, 2009

ShareFile.getURN().getAsString()
returns urn:sha1:<SHA1> of a shared file in Phex in case it was already calculated.

Thank you very much Gregor.
Are all shared files hashed through SHA1?
Where does ShareFile.getURN().getAsString() queries for the hash?

GregorK · #10 (**permalink**) May 30th, 2009

All files you share will be hashed once they are found the first time, this could take some time and getURN() will return null until there is a hash available.
The hash is saved to be available immediately after a Phex restart.
