Deluge as a service¶

Services are used to start applications on system boot and leave them running in the background. They will also stop the application nicely on system shutdown and automatically restart them if they crash.

The Deluge daemon deluged and Web UI deluge-web can both be run as services.

How to create systemd services for Linux¶

This guide walks you through setting up Deluge systemd services on Linux.

Ensure Deluge daemon deluged and Web UI deluge-web are installed. Use which to check installation paths and if necessary modify the service file ExecStart lines to point to alternative paths.

Create a service specific user¶

For security it is best to run a service with a specific user and group. You can create one using the following command:

sudo adduser --system  --gecos "Deluge Service" --disabled-password --group --home /var/lib/deluge deluge

This creates a new system user and group named deluge with no login access and home directory /var/lib/deluge which will be the default location for the config files.

In addition you can add to the deluge group any users you wish to be able to easily manage or access files downloaded by Deluge, for example:

sudo adduser <username> deluge

Daemon (deluged) service¶

Create the file /etc/systemd/system/deluged.service containing the following:

[Unit]
Description=Deluge Bittorrent Client Daemon
Documentation=man:deluged
After=network-online.target

[Service]
Type=simple
UMask=007

ExecStart=/usr/bin/deluged -d

Restart=on-failure

# Time to wait before forcefully stopped.
TimeoutStopSec=300

[Install]
WantedBy=multi-user.target

User configuration¶

To run the service using the previously created user e.g. deluge, first create the service configuration directory:

sudo mkdir /etc/systemd/system/deluged.service.d/

Then create a user file /etc/systemd/system/deluged.service.d/user.conf with the following contents:

# Override service user
[Service]
User=deluge
Group=deluge

Start deluged service¶

Now enable it to start up on boot, start the service and verify it is running:

sudo systemctl enable /etc/systemd/system/deluged.service
sudo systemctl start deluged
sudo systemctl status deluged

Umask for deluged downloaded files¶

The umask in the service file can be modified to determine access to files downloaded by deluged (also applies to logging files). Some useful access values are detailed as follows:

000 - full access for all users and groups.
007 - only user and group that deluged is running as (e.g. deluge) with no access from any other accounts.
002 - user and group deluged is running as with read-only for all other accounts.
022 - user deluged is running as with read-only for all other accounts.

The service for deluged must be stopped and started instead of just restarted after changes.

Web UI (deluge-web) service¶

Create the file /etc/systemd/system/deluge-web.service containing the following:

[Unit]
Description=Deluge Bittorrent Client Web Interface
Documentation=man:deluge-web
After=network-online.target deluged.service
Wants=deluged.service

[Service]
Type=simple
UMask=027

ExecStart=/usr/bin/deluge-web -d

Restart=on-failure

[Install]
WantedBy=multi-user.target

User configuration¶

To run the service using the previously created user e.g. deluge, first create the service configuration directory:

sudo mkdir /etc/systemd/system/deluge-web.service.d/

Then create a user file /etc/systemd/system/deluge-web.service.d/user.conf with the following contents:

# Override service user
[Service]
User=deluge
Group=deluge

Start deluge-web service¶

Now enable it to start up on boot, start the service and verify it is running:

sudo systemctl enable /etc/systemd/system/deluge-web.service
sudo systemctl start deluge-web
sudo systemctl status deluge-web

Service logging¶

Create a log directory for Deluge and give the service user (e.g. deluge), full access:

sudo mkdir -p /var/log/deluge
sudo chown -R deluge:deluge /var/log/deluge
sudo chmod -R 750 /var/log/deluge

The deluge log directory is now configured so that user deluge has full access, group deluge read only and everyone else denied access. The umask specified in the services sets the permission of new log files.

Enable logging in the service files by editing the ExecStart line, appending -l and -L options:

ExecStart=/usr/bin/deluged -d -l /var/log/deluge/daemon.log -L warning

ExecStart=/usr/bin/deluge-web -d -l /var/log/deluge/web.log -L warning

See deluged -h for all available log-levels.

Restart the services:

sudo systemctl daemon-reload
sudo systemctl restart deluged
sudo systemctl restart deluge-web

Log rotation¶

To enable log rotation append --logrotate to the above ExecStart lines.

Conditionally start deluged for mount points¶

If you have a USB disk drive or network drive that may not be immediately available on boot or disconnected at random then you may want the deluged service to wait for mount point to be ready before starting. If they are unmounted or disconnected then deluged is stopped. When they become available again deluged is started.

Ensure you have added the correct drive details to fstab or equivalent so they are mounted at boot.

List the available drive mounts:

sudo systemctl -t mount

Look for your mount point in the Description column. Mounts are formatted similar to the mount point with -s replacing /s in the path. e.g.: media-xyz.mount

Modify the [Unit] section of the deluged.service script by adding the details below, substituting xyz.mount for the mount you want the service to depend on:

[Unit]
Description=Deluge Bittorrent Client Daemon
# Start after network and specified mounts are available.
After=network-online.target xyz.mount
Requires=xyz.mount
# Stops deluged if mount points disconnect
BindsTo=xyz.mount

For multiple mount points add a space between additional entries. e.g.:

After=network-online.target xyz.mount abc.mount def.mount

Modify the [Install] section to ensure the deluged service is started when the mount point comes back online:

[Install]
WantedBy=multi-user.target xyz.mount

Reference: systemd.unit

How to create launchd services for macOS¶

The following launchd script uses a separate user deluge, this is optional but recommended for security. To create a new deluge user follow the Apple help steps.

The paths to deluged and deluge-web assumes installation using Homebrew and will need modified if using other installation methods e.g. Deluge.app.

Daemon (deluged) service¶

Create the file /Library/LaunchDaemons/org.deluge-torrent.deluged.plist containing the following:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>Label</key>
    <string>org.deluge-torrent.deluged</string>
    <key>ProgramArguments</key>
    <array>
        <string>/usr/local/bin/deluged</string>
        <string>-d</string>
        <string>-L</string>
        <string>error</string>
        <string>-l</string>
        <string>/var/log/deluged.log</string>

    -->
    <key>RunAtLoad</key>
    <true/>
    <key>KeepAlive</key>
    <true/>
</dict>
</plist>

Set the service to load on startup and then start it:

sudo launchctl load -w /Library/LaunchDaemons/org.deluge-torrent.deluged.plist
sudo launchctl start org.deluge-torrent.deluged

Web UI (deluge-web) service¶

Create the file /Library/LaunchDaemons/org.deluge-torrent.deluge-web.plist containing the following:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>Label</key>
    <string>org.deluge-torrent.deluge-web</string>
    <key>ProgramArguments</key>
    <array>
        <string>/usr/local/bin/deluge-web</string>
        <string>-d</string>
        <string>-L</string>
        <string>error</string>
        <string>-l</string>
        <string>/var/log/deluge-web.log</string>
    </array>
    <key>StandardOutPath</key>
    <string>/tmp/deluge-web.stdout</string>
    <key>StandardErrorPath</key>
    <string>/tmp/deluge-web.stderr</string>
    <!-- To enable running as 'deluge' user remove comments.
    <key>UserName</key>
    <string>deluge</string>
    -->
    <key>RunAtLoad</key>
    <true/>
    <key>KeepAlive</key>
    <true/>
</dict>
</plist>

Set the service to load on startup and then start it:

sudo launchctl load -w /Library/LaunchDaemons/org.deluge-torrent.deluge-web.plist
sudo launchctl start org.deluge-torrent.deluge-web

Logging¶

Logging is enabled by default in the above script, error level, and can be modified as required.

How to create NSSM services for Windows¶

Download NSSM and read their usage page about installing.

In order for the services to be stopped properly, use the debug application versions (ending in -debug.exe).

Daemon (deluged) service¶

Create a deluged service:

nssm install deluged

The following are minimum UI changes required for the service to work:

Path: C:\Program Files\Deluge\deluged-debug.exe
Arguments: -c C:\config_location

Web UI (deluge-web) service¶

nssm install deluge-web

Path: C:\Program Files\Deluge\deluge-web-debug.exe
Arguments: -c C:\config_location

If Web UI is not accessible outside your machine (if you’re running Deluge from a home server), you have to whitelist Deluge in your Windows Firewall for the deluge-web and deluge-web-debug executable.

2.0.0 (2019-06-06)¶

Codebase¶

Ported to Python 3

Core¶

Improved Logging
Removed the AutoAdd feature on the core. It’s now handled with the AutoAdd plugin, which is also shipped with Deluge, and it does a better job and now, it even supports multiple users perfectly.
Authentication/Permission exceptions are now sent to clients and recreated there to allow acting upon them.
Updated SSL/TLS Protocol parameters for better security.
Make the distinction between adding to the session new unmanaged torrents and torrents loaded from state. This will break backwards compatibility.
Pass a copy of an event instead of passing the event arguments to the event handlers. This will break backwards compatibility.
Allow changing ownership of torrents.
File modifications on the auth file are now detected and when they happen, the file is reloaded. Upon finding an old auth file with an old format, an upgrade to the new format is made, file saved, and reloaded.
Authentication no longer requires a username/password. If one or both of these is missing, an authentication error will be sent to the client which should then ask the username/password to the user.
Implemented sequential downloads.
Provide information about a torrent’s pieces states
Add Option To Specify Outgoing Connection Interface.
Fix potential for host_id collision when creating hostlist entries.

Gtk UI¶

Ported to GTK3 (3rd-party plugins will need updated).
Allow changing ownership of torrents.
Host entries in the Connection Manager UI are now editable.
Implemented sequential downloads UI handling.
Add optional pieces bar instead of a regular progress bar in torrent status tab.
Make torrent opening compatible with all Unicode paths.
Fix magnet association button on Windows.
Add keyboard shortcuts for changing queue position:
- Up: Ctrl+Alt+Up
- Down: Ctrl+Alt+Down
- Top: Ctrl+Alt+Shift+Up
- Bottom: Ctrl+Alt+Shift+Down

Web UI¶

Server (deluge-web) now daemonizes by default, use ‘-d’ or ‘–do-not-daemonize’ to disable.
Fixed the ‘–base’ option to work for regular use, not just with reverse proxies.

Blocklist Plugin¶

Implemented whitelist support to both core and GTK UI.
Implemented IP filter cleaning before each update. Restarting the deluge daemon is no longer needed.
If “check_after_days” is 0(zero), the timer is not started anymore. It would keep updating one call after the other. If the value changed, the timer is now stopped and restarted using the new value.

Deluge 2.0 release notes¶

Welcome to the latest release of Deluge, a long time in the making!

What’s new¶

Some of the highlights since the last major release.

Migrated to Python 3 with minimal support retained for Python 2.7.
Shiny new logo.
Multi-user support.
Performance updates to handle thousands of torrents with faster loading times.
A New Console UI which emulates GTK/Web UIs.
GTK UI migrated to GTK3 with UI improvements and additions.
Magnet pre-fetching to allow file selection when adding torrent.
Fully support libtorrent 1.2 release.
Language switching support.
Improved documentation hosted on ReadTheDocs.
AutoAdd plugin replaces built-in functionality.
Web UI now daemonizes by default so service scripts will require -d option.

Packaging¶

PyPi¶

As well as the usual source tarball available for download we now have published Deluge on the PyPi software repository.

https://pypi.org/project/deluge/

Windows and MacOS¶

Unfortunately there are no packages yet for Windows or MacOS but they are being worked on. For now alternative install methods are available for testing.

Upgrade considerations¶

Deluge 2.0 is not compatible with Deluge 1.x clients or daemons so these will require upgrading too. Also third-party Python scripts may not be compatible if they directly connect to the Deluge client and will need migrating.

Always make a backup of your config before a major version upgrade to guard against data loss.

Translations may not be as up-to date so please help out, see translations page.

Plugins written for Deluge 1.3 will need upgrading for Deluge 2.0, due to the requirement of Python 3 and GTK3 UI. There is a update plugin document to help Plugin authors update their plugins.

Development & community¶

Deluge is an open-source project, and relies on its community of users to keep getting better.

Contributing code¶

Basic requirements and standards¶

A new ticket is required for bugs or features. Search the ticket system first, to avoid filing a duplicate.
Ensure code follows the syntax and conventions.
Code must pass tests. See testing document for information on how to run and write unit tests.
Commit messages are informative.

Pull request process:¶

Fork us on GitHub.
Clone your repository.
Create a feature branch for your issue.
Apply your changes:
- Add them, and then commit them to your branch.
- Run the tests until they pass.
- When you feel you are finished, rebase your commits to ensure a simple and informative commit log.
Create a pull request on GitHub from your forked repository.
- Verify that the tests run by Travis-ci are passing.

Syntax and conventions¶

Code formatting¶

We use two applications to automatically format the code to save development time. They are both run with pre-commit.

Black¶

Python

Prettier¶

JavaScript
CSS
YAML
Markdown

Common¶

Line length: 79 chars.
Indent: 4 spaces, no tabs.
All code should use 'single quotes'.

Python¶

We follow PEP8 and Python Code Style which is adhered to with Black.

Code ‘’’must’’’ pass Black, flake8 and isort source code checkers. (Optionally Pylint)

  flake8 deluge
  isort -rc -df deluge
  pylint deluge
  pylint deluge/plugins/\*/deluge/

Using the pre-commit application can aid in identifying issues while creating git commits.

Strings and bytes¶

To prevent bugs or errors in the code byte strings (str) must be decoded to strings (Unicode text strings, unicode) on input and then encoded on output.

Notes:

PyGTK/GTK+ will accept str (UTF-8 encoded) or unicode but will only return str. See GTK3 Unicode docs.
There is a bytearray type which enables in-place modification of a string. See Python Bytearrays
Python 3 renames unicode to str type and byte strings become bytes type.

JavaScript¶

Classes should follow the Ext coding style.
Class names should be in !CamelCase
Instances of classes should use camelCase.

Path separators¶

All relative path separators used within code should be converted to posix format /, so should not contain \ or \\. This is to prevent confusion when dealing with cross-platform clients and servers.

Docstrings¶

All new docstrings must use Napoleon Google Style with old docstrings eventually converted over.

Google Style example:

def func(arg):
   """Function purpose.

   Args:
       arg (type): Description.

   Returns:
      type: Description. If the line is too, long indent next
         line with three spaces.
   """
   return

See complete list of supported headers.

Verify that the documentation parses correctly with:

python setup.py build_docs

Running tests¶

Deluge testing is implemented using Trial which is Twisted’s testing framework and an extension of Python’s unittest.

See Twisted website for documentation on Twisted Trial and Writing tests using Trial.

Testing¶

The tests are located in the source folder under deluge/tests. The tests are run from the project root directory. View the unit test coverage at: deluge-torrent.github.io

Trial¶

Here are some examples that show running all the tests through to selecting an individual test.

trial deluge
trial deluge.tests.test_client
trial deluge.tests.test_client.ClientTestCase
trial deluge.tests.test_client.ClientTestCase.test_connect_localclient

Pytest¶

pytest deluge/tests
pytest deluge/tests/test_client.py
pytest deluge/tests/test_client.py -k test_connect_localclient

Plugin¶

Running the tests for a specific plugin (requires pytest):

pytest deluge/plugins/<name-of-plugin>

Tox¶

All the tests for Deluge can be run using Tox

See available targets:¶

tox -l
py27
py3
lint
docs

Run specific test:¶

tox -e py3

Verify code with pre-commit:¶

tox -e lint

Travis CI¶

Deluge develop branch is tested automatically by Travis. When creating a pull request (PR) on github, Travis will automatically run the unit tests with the code in the PR.

Documentation contributions¶

Build¶

We use Sphinx to create the documentation from source files and docstrings in code.

pip install -r docs/requirements.txt
python setup.py build_docs

The resulting html files are in docs/build/html.

man pages¶

Located in docs/man

Translation contributions¶

Translators¶

For translators we have a Launchpad translations account where you can translate the .po files.

Marking text for translation¶

To mark text for translation in Python and ExtJS wrap the string with the function _() like this:

torrent.set_tracker_status(_("Announce OK"))

For GTK the text can also be marked translatable in the glade/*.ui files:

<property name="label" translatable="yes">Max Upload Speed:</property>

For more details see: Python Gettext

Translation process¶

These are the overall stages in gettext translation:

Portable Object Template -> Portable Object -> Machine Object

The deluge.pot is created using generate_pot.py.
Upload deluge/i18n/deluge.pot to Launchpad translations.
Give the translators time to translate the text.
Download the updated .po files from translation site.
Extract to deluge/i18n/ and strip the deluge- prefix:
```
 rename -f 's/^deluge-//' deluge-*.po
```
The binary MO files for each language are generated by setup.py using the msgfmt.py script.

To enable Web UI to use translations update gettext.js by running gen_gettext.py script.

Useful applications¶

podiff - Compare textual information in two PO files
gtranslator - GUI PO file editor
Poedit - GUI PO file editor

Testing translation¶

Testing that translations are working correctly can be performed by running Deluge as follows.

Create an MO for a single language in the correct sub-directory:

mkdir -p deluge/i18n/fr/LC_MESSAGES
python msgfmt.py -o deluge/i18n/fr/LC_MESSAGES/deluge.mo deluge/i18n/fr.po

Run Deluge using an alternative language:

LANGUAGE=fr deluge
LANGUAGE=ru_RU.UTF-8 deluge

Note: If you do not have a particular language installed on your system it will only translate based on the MO files for Deluge so some GTK text/button strings will remain in English.

Development guide¶

This is a guide to help with developing Deluge.

Developer tutorials¶

A list of articles to help developers get started with Deluge.

Setup tutorial for Deluge development¶

The aim of this tutorial is to download the source code and setup an environment to enable development work on Deluge.

Pre-requisites¶

To build and run the Deluge applications they depends on tools and libraries as listed in DEPENDS.md.

Almost all of the Python packages dependencies will be installed using pip but there are some packages or libraries that are required to be installed to the system.

Ubuntu¶

Build tools¶

sudo apt install git intltool closure-compiler python3-pip
pip3 install --user tox

You might need to add ~/.local/bin to your PATH.

Runtime libraries and tools¶

sudo apt install python3-libtorrent python3-geoip python3-dbus  python3-gi \
python3-gi-cairo gir1.2-gtk-3.0 gir1.2-appindicator3 python3-pygame libnotify4 \
librsvg2-common xdg-utils

Setup development environment¶

Clone Deluge git repository¶

Download the latest git code to local folder.

git clone git://deluge-torrent.org/deluge.git
cd deluge

Create Python virtual environment¶

Creation of a [Python virtual environment] keeps the development isolated and easier to maintain and Tox has an option to make this process easier:

tox -e denv

Activate virtual environment:

source .venv/bin/activate

Deluge will be installed by Tox in develop mode which creates links back to source code so that changes will be reflected immediately without repeated installation. Check it is installed with:

(.venv) $ deluge --version
deluge-gtk 2.0.0b2.dev149
libtorrent: 1.1.9.0
Python: 2.7.12
OS: Linux Ubuntu 16.04 xenial

Setup pre-commit hook¶

Using pre-commit ensures submitted code is checked for quality when creating git commits.

(.venv) $ pre-commit install

You are now ready to start playing with the source code.

How-to guides¶

A collection of guides for specific issues or to cover more detail than the tutorials.

Web JSON-RPC¶

How to connect to JSON-RPC with curl¶

Before continuing make sure deluge-web or Web UI plugin is running.

Create a curl configuration file¶

To save a lot of typing and to keep the curl command short we shall create a curl.cfg files and put the following contents in it:

request = "POST"
compressed
cookie = "cookie_deluge.txt"
cookie-jar = "cookie_deluge.txt"
header = "Content-Type: application/json"
header = "Accept: application/json"
url = "http://localhost:8112/json"
write-out = "\n"

To pretty-print the JSON result see: https://stackoverflow.com/q/352098/175584

Log in to Web UI¶

Log in to the Web UI and get session cookie:

curl -d '{"method": "auth.login", "params": ["deluge"], "id": 1}' -K curl.cfg

Result is true to signify that login was successful:

{
    "error": null,
    "id": 1,
    "result": true
}

Check the contents of the cookie file to verify session ID created.

cat cookie_deluge.txt
# Netscape HTTP Cookie File
# http://curl.haxx.se/docs/http-cookies.html
# This file was generated by libcurl! Edit at your own risk.

localhost	FALSE	/json	FALSE	1540061203	_session_id	<session_id>

Check connected to deluged¶

Use the web.connected method to get a boolean response if the Web UI is connected to a deluged host:

curl -d '{"method": "web.connected", "params": [], "id": 1}' -K curl.cfg

Result is false because Web UI is not yet connected to the daemon:

{
    "error": null,
    "id": 1,
    "result": false
}

Get list of deluged hosts¶

Use the web.get_hosts method:

curl -d '{"method": "web.get_hosts", "params": [], "id": 1}' -K curl.cfg

The result contains the <hostID> for using in request params field.

{
    "error": null,
    "id": 1,
    "result": [
        [
            "<hostID>",
            "127.0.0.1",
            58846,
            "localclient"
        ]
    ]
}

Get the deluged host status¶

curl -d '{"method": "web.get_host_status", \
"params": ["<hostID>"], "id": 1}' -K curl.cfg

The result shows the version and status; online, offline or connected.

{
    "error": null,
    "id": 1,
    "result": [
        "<hostID>",
        "Online",
        "2.0.0"
    ]
}

Connect to deluged host¶

To connect to deluged with <hostID>:

curl -d '{"method": "web.connect", \
"params": ["<hostID>"], "id": 1}' -K curl.cfg

The result contains the full list of available host methods:

{
    "error": null,
    "id": 1,
    "result": [
        "core.add_torrent_url",
        ...
        "core.upload_plugin"
    ]
}

Disconnect from host¶

curl -d '{"method": "web.disconnect", "params": [], "id": 1}' -K curl.cfg

A successful result:

{
    "error": null,
    "id": 1,
    "result": "Connection was closed cleanly."
}

Add a torrent¶

Plugins¶

How to update a Deluge 1.3 plugin for 2.0¶

With the new code in Deluge 2.0 there are changes that require authors of existing plugins to update their plugins to work on Deluge 2.0.

The main changes are with Python 3 support and the new GTK3 user interface with the dropping of GTK2. However it is still possible for a 1.3 plugin to be made compatible with 2.0 and this guide aims to helps with that process.

Python¶

Python version matching¶

Ensure your code is both Python 2.7 and Python >=3.5 compatible.

In 1.3-stable the plugins that were built with a specific version of Python would only be loaded if the system Python also matched.

This has change in Deluge 2.0 and it will load any Python version of plugin eggs so compatibility is essential for end-users not to encounter issues.

Six¶

Use six to assist with compatibility.

Unicode literals¶

Add the following to files to ensure strings and bytes separation so there are no surprises when running on Python 3.

from __future__ import unicode_literals

GTK 3 addition¶

In order to support both Deluge 1.3 and 2.0 all existing plugin GTK UI files must be copied and then converted to contain only GTK3 code with the old files still using PyGTK e.g.:

cp gtkui.py gtk3ui.py

Convert from libglade to GtkBuilder¶

With PyGTK there were two library options for creating the user interface from XML files by default Deluge plugins used libglade but that has been deprecated and removed in GTK3. So the libglade .glade files will need converted to GtkBuilder .ui files and the Python code updated.

See the official Migrating to GtkBuilder document for more details.

GtkBuilder conversion script¶

Install the gtk-builder-convert converter on Ubuntu with:

sudo apt install libgtk2.0-dev

To convert your GTK run it like so:

gtk-builder-convert data/config.glade data/config.ui

Glade UI designer for GTK2¶

The above conversion can also be done in Glade UI designer (version <=3.8).

In the preferences select GtkBuilder as the project file format. Ensure that the minimum Gtk version is set to 2.24 and fix any deprecated widgets.

The updated file should be saved with file extension .ui.

Python code changes¶

The code needs to replace gtk.glade references with gtk.Builder and the first step is updating how the files are loaded:

- glade = gtk.glade.XML(get_resource("config.glade"))
+ builder = Gtk.Builder.new_from_file(get_resource("config.ui"))

Replace signals method:

- glade.signal_autoconnect(self)
+ builder.connect_signals(self)

Replace get_widget with get_object:

- glade.get_widget
+ builder.get_object

Check for any remaining glade methods and replace with the builder equivalents.

Migrate XML files to GTK3¶

If you open and save the file it will update with the new requirement header:

<!-- Generated with glade 3.18.3 -->
<interface>
  <requires lib="gtk+" version="3.10"/>

You can fix deprecated widgets but keep the minimum GTK version to <= 3.10 for desktop compatibility.

An example of migrating a Deluge plugin to GtkBuilder: AutoAdd GtkBuilder

Gtk import rename¶

Move from PyGTK to GTK3 using Python bindings.

https://pygobject.readthedocs.io/en/latest/guide/porting.html

wget https://gitlab.gnome.org/GNOME/pygobject/raw/master/tools/pygi-convert.sh
cp gtkui.py gtk3ui.py
sh pygi-convert.sh gtk3ui.py

-import gtk
+from gi.repository import Gtk

- self.builder = gtk.Builder()
+ self.builder = Gtk.Builder()

Deluge GTK3¶

Imports¶

Imports will need renamed from deluge.ui.gtkui to deluge.ui.gtk3.

There is also a new PluginBase for Gtk3 UI:

-from deluge.plugins.pluginbase import GtkPluginBase
+from deluge.plugins.pluginbase import Gtk3PluginBase
-class GtkUI(GtkPluginBase):
+class Gtk3UI(Gtk3PluginBase):

Entry points¶

To enable the GTK3 UI to find the plugin the entry points requires updating too.

In the plugin __init__.py file add a new Gtk3UIPlugin class:

class Gtk3UIPlugin(PluginInitBase):
    def __init__(self, plugin_name):
        from .gtk3ui import Gtk3UI as _plugin_cls
        self._plugin_cls = _plugin_cls
        super(Gtk3UIPlugin, self).__init__(plugin_name)

A new entry for GTK3 UI can then be added to setup.py:

     [deluge.plugin.gtkui]
     %s = %s:GtkUIPlugin
+    [deluge.plugin.gtk3ui]
+    %s = deluge_%s:Gtk3UIPlugin
     [deluge.plugin.webui]
     %s = %s:WebUIPlugin
-    """ % ((__plugin_name__, __plugin_name__.lower())*3)
+    """ % ((__plugin_name__, __plugin_name__.lower())*4)

Packaging documentation¶

Release Checklist¶

Pre-release¶

Update translation po files from Launchpad account.
Changelog is updated with relevant commits and release date is added.
Docs release notes are updated.

Tag release in git and push upstream e.g.

git tag -a deluge-2.0.0 -m "Deluge 2.0.0 Release"

Release¶

Create source and wheel distributions:
```
python setup.py sdist bdist_wheel
```

Upload to PyPi (currently only accepts tar.gz):

twine upload dist/deluge-2.0.0.tar.gz dist/deluge-2.0.0-py3-none-any.whl

Calculate sha256sum for each file e.g.

cd dist; sha256sum deluge-2.0.0.tar.xz > deluge-2.0.0.tar.xz.sha256

Upload source tarballs and packages to download.deluge-torrent.org.
- Ensure file permissions are global readable: 0644
- Sub-directories correspond to major.minor version e.g. all 2.0.x patch releases are stored in source/2.0.
- Change release version in version files.
- Run trigger-deluge to sync OSUOSL FTP site.
Create packages (Ubuntu, Windows, OSX).
- Ubuntu: https://code.launchpad.net/~deluge-team/+recipe/stable-releases

Post-release¶

Update with version, hashes and release notes:
- Publish docs on ReadTheDocs.
- Forum announcement.
- IRC welcome message.
- Wikipedia
Close Trac milestone and add new milestone version for future tickets.
Ensure all stable branch commits are also applied to development branch.

Launchpad recipe¶

The launchpad build recipes are for build from source automatically to provide Ubuntu packages. They are used to create daily builds of a Deluge git branch.

Note these don’t have the same control as a creating a publishing to PPA.

Main reference: https://help.launchpad.net/Packaging/SourceBuilds/Recipes

Deluge Launchpad build recipes¶

Recipe configuration: https://code.launchpad.net/~deluge-team/+recipes

An example for building the develop branch:

# git-build-recipe format 0.4 deb-version 2.0.0.dev{revno}+{git-commit}+{time}
lp:deluge develop
nest-part packaging lp:~calumlind/+git/lp_deluge_deb debian debian develop

There are two parts, first to get the source code branch and then the debian files for building the package.

Testing and building locally¶

Create a deluge.recipe file with the contents from launchpad and create the build files with git-build-recipe:

git-build-recipe --allow-fallback-to-native deluge.recipe lp_build

Setup pbuilder and build the deluge package:

sudo pbuilder build lp_build/deluge*.dsc

Alternatively to build using local files with pdebuild:

cd lp_build/deluge/deluge
pdebuild

This will allow modifying the debian files to test changes to rules or control.

Packaging for Windows¶

Currently there is no working package for Deluge 2.0. The previous Python freezing application bbfreeze is not compatible with Python 3 and the project is no longer maintained.

There are two alternatives cxfreeze and pyinstaller but neither is trivial with the GTKUI application.

See #3201

Deluge Web UI¶

The Deluge web interface is a full featured interface built using the ExtJS framework, running on top of a Twisted web server.

SSL Configuration¶

By default the web interface will use the same private key and certificate as the Deluge daemon. You can use a different certificate/key and specify it in the Web UI config, see below for details.

Create SSL Certificate Examples¶

Sample guide: How to Create a SSL Certificate

Linux¶

openssl req -new -x509 -nodes -out deluge.cert.pem -keyout deluge.key.pem

Windows¶

C:\OpenSSL\bin\openssl.exe req -config C:\OpenSSL\bin\openssl.cnf -x509 -days 365 -newkey rsa:1024 -keyout hostkey.pem -nodes -out hostcert.pem

Enable Web UI SSL¶

There are two ways to enable SSL encryption in the web server:

Specify in your config (accessible via the Preferences window).
Use --ssl when running the web server, overriding the configuration value to enable SSL.

Enable Development mode¶

Append ?dev=true to the Web UI URL to enable development mode, uses the source JavaScript files (if available) rather than compressed versions:

http://127.0.0.1:8112/?dev=true

Deluge RPC¶

Message Formats¶

DelugeRPC is a protocol used for daemon/client communication. There are four types of messages involved in the protocol: RPC Request, RPC Response, RPC Error and Event. All messages are zlib compressed with rencode encoded strings and their data formats are detailed below.

RPC Request¶

This message is created and sent by the client to the server requesting that a remote method be called. Multiple requests can be bundled in a list.

[[request_id, method, [args], {kwargs}], …]

request_id (int): An integer determined by the client that is used in replies from the server. This is used to ensure the client knows which request the data is in response to. Another alternative would be to respond in the same order the requests come in, but this could cause lag if an earlier request takes longer to process.
method (str): The name of the remote method to call. This name can be in dotted format to call other objects or plugins methods.
args (list): The arguments to call the method with.
kwargs (dict): The keyword arguments to call the method with.

RPC Response¶

This message is created and sent in response to a RPC Request from a client. It will hold the return value of the requested method call. In the case of an error, a RPC Error message will be sent instead.

[message_type, request_id, [return_value]]

message_type (int): This will be a RPC_RESPONSE type id. This is used on the client side to determine what kind of message is being received from the daemon.
request_id (int): The request_id is the same as the one sent by the client in the initial request. It used on the client side to determine what message this is in response to.
return_value (list): The return value of the method call.

RPC Error¶

This message is created in response to an error generated while processing a RPC Request and will serve as a replacement for a RPC Response message.

[message_type, request_id, exception_type, exception_msg, traceback]

message_type (int): This will be a RPC_ERROR type id.
request_id (int): The request_id is the same as the one sent by the client in the initial request.
exception_type (str): The type of exception raised.
exception_msg (str): The message as to why the exception was raised.
traceback (str): The traceback of the generated exception.

Event¶

This message is created by the daemon and sent to the clients without being in response to a RPC Request. Events are generally sent for changes in the daemon’s state that the clients need to be made aware of.

[message_type, event_name, data]

message_type (int): This will be a RPC_EVENT type id.
event_name (str): This is the name of the event being emitted by the daemon.
data (list): Additional data to be sent with the event. This is dependent upon the event being emitted.
