Source

You can check out TracDownloaderPlugin from here using Subversion, or browse the source with Trac.

Installation

EGG
The easiest way to start using Downloader plug-in is to get downloaded python egg into plugin directory of project environment (egg is most probably python version independent, just rename it, but who knows, there's still source package...), after that you must turn both modules of Downloader on in WebAdmin/plugins (Downloader is dependent on WebAdmin plug-in). And finally there is need to get some permissions of Downloader to some users... In this case if you like to use PyCaptcha, you must take care of installing it by yourself, PyCaptcha is dependent on PIL so you must download it too.

SOURCE - installation with PyCaptcha and Python Imaging Library (PIL) which are needed for Captcha to work

easy_install --find-links http://www.pythonware.com/products/pil/ Imaging
easy_install PyCaptcha
easy_install http://trac-hacks.org/svn/tracdownloaderplugin/0.10/

Second and maybe better way is to download and unpack somewhere source zip package and then just run "setup.py install" (or on windows maybe better "python setup.py install") or you can just use easy_install commands written above. Setup should take care of all dependences (PyCaptcha and PIL but it could get some errors while dowloading them so if automatic dependency resolution doesn't work use code above) and prepare plugin to be turned on in WebAdmin/plugins. Setup just installs TracDownloaderPlugin. If you like to use Captcha tests you have to install PIL and PyCaptcha manually either (note that PIL is in most Linux distributions package named python-imaging so you don't need to install it by easy install but you can use your package manager). Then you must enable both Downloader modules in TracAdmin/Plugins (or enable Downoader components in your envronment's ini file - source bottom) and assign some permissions of downloader to someone and you can start trying Downloader plug-in...

[components]
tracdownloader.admin.downloaderadminpage = enabled
tracdownloader.web_ui.downloadermodule = enabled

After steps above and clicking to any part of Downloader you should be asked about location of directory to store uploaded files. When it is set up, you must Submit that form two times and there can occur exception "DatabaseError: database schema has changed". If this exception is thrown, it's best to restart your http server.

Downloader keeps using ClearSilver as templating system so you have to have it installed (version for new templating system Genshe will be written soon). Version for Trac 0.11 wasn't too much tested so if you find errors, please write me a ticket as soon as possible.

If you had problems installing Downloader, please write me a ticket or write solution of your installation problems here.

Permissions

Downloader plug-in defines three permissions:

DOWNLOADER_DOWNLOAD - lets user to download things from main part of plug-in, if you like to let all users download from donwloader, just get this permission to user anonymous.
DOWNLOADER_STATS - lets user to browse part of statistics in the main module of Downloader (user will be able to see links to statistics in the right top corner of the page).
DOWNLOADER_ADMIN - lets user to upload files, manage files, releases and categories, browse fill up's of questionnaire, delete fill up's of questionnaire and manage settings of Downloader plug-in. Note that this permission should never be given to user anonymous!

Wiki syntax

Downloader plug-in provides three types of wiki syntax for referencing of standalone files, whole releases or categories. Each syntax have two possible forms. If syntax is enclosed by [] you can easily write your own title for item (file, release, category). If the syntax is separated just by spaces, there will be automatically created link with name of referenced item (file, release, category).

Syntaxes:

downloader:5 - Creates link to file with id 5 with it's name
[downloader:5 click here] - Creates 'click here' link to file with id 5

downloaderrel:23 - Creates link to release with id 23 with it's name
[downloaderrel:23 click here] - Creates 'click here' link to release with id 23

downloadercat:43 - Creates link to category with id 43 with it's name
[downloadercat:43 click here] - Creates 'click here' link to category with id 43


If item of that id doesn't exist, there's diplayed only link to nowhere with title "id not found". If file was deleted, it still displays it's correct name, but link is to nowhere.

Special features

This features are availible only if you have Downloader installed in unzipped form (doesn't work in egg or zip file).

MIME list In tracdownloader directroy there is a file mime_list.txt which contains list of known MIME types for downloader, you can easily add new ones or delete unneeded, if there is no record found for particular file extension in this list, Downloader uses MIME of application/octet-stream.

EDIT QUESTIONNAIRE The file form_data.py contains structure used to generate questionnaire before download of file. You can easily edit this to get from users the data you exactly want. There is big decription inside of this file.

Reset all statistics

To clear all recorded data about dowloads and users who downloaded anything by DownloaderPlugin you can use on your Trac environment database these two SQL commands.

DELETE FROM downloader_downloaded_attributes;
DELETE FROM downloader_downloaded;

That's all... After this all statistics are gone...
