### About Radicale
|
||
|
||
Radicale is a small but powerful CalDAV (calendars, todo-lists) and CardDAV
|
||
(contacts) server, that:
|
||
|
||
* Shares calendars through CalDAV, WebDAV and HTTP.
|
||
* Shares contacts through CardDAV, WebDAV and HTTP.
|
||
* Supports events, todos, journal entries and business cards.
|
||
* Works out-of-the-box, no installation nor configuration required.
|
||
* Can warn users on concurrent editing.
|
||
* Can limit access by authentication.
|
||
* Can secure connections.
|
||
* Works with many CalDAV and CardDAV clients.
|
||
* Is GPLv3-licensed free software.
|
||
|
||
### Installation
|
||
|
||
Radicale is really easy to install and works out-of-the-box.
|
||
|
||
```bash
|
||
$ python3 -m pip install --upgrade radicale
|
||
$ python3 -m radicale --config "" --storage-filesystem-folder=~/.var/lib/radicale/collections
|
||
```
|
||
|
||
When your server is launched, you can check that everything's OK by going
|
||
to http://localhost:5232/ with your browser!
|
||
You can login with any username and password.

## Tutorial
|
||
|
||
You want to try Radicale but only have 5 minutes free in your calendar? Let's
|
||
go right now! You won't have the best installation ever, but it will be enough
|
||
to play a little bit with Radicale.
|
||
|
||
When everything works, you can get a [client](#documentation/clients) and
|
||
start creating calendars and address books. The server **only** binds to
|
||
localhost (is **not** reachable over the network) and you can log in with any
|
||
user name and password. If Radicale fits your needs, it may be time for
|
||
[some basic configuration](#documentation/basic-setup).
|
||
|
||
Follow one of the chapters below depending on your operating system.
|
||
|
||
### Linux / \*BSD
|
||
|
||
First of all, make sure that **python** 3.3 or later (**python** ≥ 3.6 is
|
||
recommended) and **pip** are installed. On most distributions it should be
|
||
enough to install the package ``python3-pip``.
|
||
|
||
Then open a console and type:
|
||
|
||
```bash
|
||
# Run the following command as root or
|
||
# add the --user argument to only install for the current user
|
||
$ python3 -m pip install --upgrade radicale
|
||
$ python3 -m radicale --config "" --storage-filesystem-folder=~/.var/lib/radicale/collections
|
||
```
|
||
|
||
Victory! Open [http://localhost:5232/](http://localhost:5232/) in your browser!
|
||
You can login with any username and password.
|
||
|
||
### Windows
|
||
|
||
The first step is to install Python. Go to
|
||
[python.org](https://python.org) and download the latest version of Python 3.
|
||
Then run the installer.
|
||
On the first window of the installer, check the "Add Python to PATH" box and
|
||
click on "Install now". Wait a couple of minutes, it's done!
|
||
|
||
Launch a command prompt and type:
|
||
|
||
```powershell
|
||
C:\Users\User> python -m pip install --upgrade radicale
|
||
C:\Users\User> python -m radicale --config "" --storage-filesystem-folder=~/radicale/collections
|
||
```
|
||
|
||
If you are using PowerShell replace ``--config ""`` with ``--config '""'``.
|
||
|
||
Victory! Open [http://localhost:5232/](http://localhost:5232/) in your browser!
|
||
You can login with any username and password.
|
||
|
||
### MacOS
|
||
|
||
*To be written.*
|
||
|
||
## Basic Setup
|
||
|
||
Installation instructions can be found on the
|
||
[Tutorial](#documentation/tutorial) page.
|
||
|
||
### Configuration
|
||
|
||
Radicale tries to load configuration files from `/etc/radicale/config`,
|
||
`~/.config/radicale/config` and the `RADICALE_CONFIG` environment variable.
|
||
A custom path can be specified with the `--config /path/to/config` command
|
||
line argument.
|
||
|
||
You should create a new configuration file at the desired location.
|
||
(If the use of a configuration file is inconvenient, all options can be
|
||
passed via command line arguments.)
|
||
|
||
All configuration options are described in detail on the
|
||
[Configuration](#documentation/configuration) page.
|
||
|
||
### Authentication
|
||
|
||
In its default configuration Radicale doesn't check user names or passwords.
|
||
If the server is reachable over a network, you should change this.
|
||
|
||
First a `users` file with all user names and passwords must be created.
|
||
It can be stored in the same directory as the configuration file.
|
||
|
||
#### The secure way
|
||
|
||
The `users` file can be created and managed with
|
||
[htpasswd](https://httpd.apache.org/docs/current/programs/htpasswd.html):
|
||
```bash
|
||
# Create a new htpasswd file with the user "user1"
|
||
$ htpasswd -B -c /path/to/users user1
|
||
New password:
|
||
Re-type new password:
|
||
# Add another user
|
||
$ htpasswd -B /path/to/users user2
|
||
New password:
|
||
Re-type new password:
|
||
```
|
||
**bcrypt** is used to secure the passwords. Radicale requires additional
|
||
dependencies for this encryption method:
|
||
```bash
|
||
$ python3 -m pip install --upgrade radicale[bcrypt]
|
||
```
|
||
|
||
Authentication can be enabled with the following configuration:
|
||
```ini
|
||
[auth]
|
||
type = htpasswd
|
||
htpasswd_filename = /path/to/users
|
||
# encryption method used in the htpasswd file
|
||
htpasswd_encryption = bcrypt
|
||
```
|
||
|
||
#### The simple but insecure way
|
||
|
||
Create the `users` file by hand with lines containing the user name and
|
||
password separated by `:`. Example:
|
||
|
||
```htpasswd
|
||
user1:password1
|
||
user2:password2
|
||
```
|
||
|
||
Authentication can be enabled with the following configuration:
|
||
```ini
|
||
[auth]
|
||
type = htpasswd
|
||
htpasswd_filename = /path/to/users
|
||
# encryption method used in the htpasswd file
|
||
htpasswd_encryption = plain
|
||
```
|
||
|
||
### Addresses
|
||
|
||
The default configuration binds the server to localhost. It can't be reached
|
||
from other computers. This can be changed with the following configuration
|
||
options:
|
||
|
||
```ini
|
||
[server]
|
||
hosts = 0.0.0.0:5232
|
||
```
|
||
|
||
More addresses can be added (separated by commas).
|
||
|
||
### Storage
|
||
|
||
Data is stored in the folder `/var/lib/radicale/collections`. The path can
|
||
be changed with the following configuration:
|
||
|
||
```ini
|
||
[storage]
|
||
filesystem_folder = /path/to/storage
|
||
```
|
||
|
||
**Security:** The storage folder should not be readable by unauthorized users.
|
||
Otherwise, they can read the calendar data and lock the storage.
|
||
You can find OS dependent instructions in the **Running as a service** section.
|
||
|
||
### Limits
|
||
|
||
Radicale enforces limits on the maximum number of parallel connections,
|
||
the maximum file size (important for contacts with big photos) and the rate of
|
||
incorrect authentication attempts. Connections are terminated after a timeout.
|
||
The default values should be fine for most scenarios.
|
||
|
||
```ini
|
||
[server]
|
||
max_connections = 20
|
||
# 100 Megabyte
|
||
max_content_length = 100000000
|
||
# 30 seconds
|
||
timeout = 30
|
||
|
||
[auth]
|
||
# Average delay after failed login attempts in seconds
|
||
delay = 1
|
||
```
|
||
|
||
### Running as a service
|
||
|
||
The method to run Radicale as a service depends on your host operating system.
|
||
Follow one of the chapters below depending on your operating system and
|
||
requirements.
|
||
|
||
#### Linux with systemd as a user
|
||
|
||
Create the file `~/.config/systemd/user/radicale.service`:
|
||
```ini
|
||
[Unit]
|
||
Description=A simple CalDAV (calendar) and CardDAV (contact) server
|
||
|
||
[Service]
|
||
ExecStart=/usr/bin/env python3 -m radicale
|
||
Restart=on-failure
|
||
|
||
[Install]
|
||
WantedBy=default.target
|
||
```
|
||
|
||
Radicale will load the configuration file from `~/.config/radicale/config`.
|
||
You should set the configuration option `filesystem_folder` in the `storage`
|
||
section to something like `~/.var/lib/radicale/collections`.
|
||
|
||
To enable and manage the service run:
|
||
```bash
|
||
# Enable the service
|
||
$ systemctl --user enable radicale
|
||
# Start the service
|
||
$ systemctl --user start radicale
|
||
# Check the status of the service
|
||
$ systemctl --user status radicale
|
||
# View all log messages
|
||
$ journalctl --user --unit radicale.service
|
||
```
|
||
|
||
#### Linux with systemd system-wide
|
||
|
||
Create the **radicale** user and group for the Radicale service.
|
||
(Run `useradd --system --home-dir / --shell /sbin/nologin radicale` as root.)
|
||
The storage folder must be writable by **radicale**. (Run
|
||
`mkdir -p /var/lib/radicale/collections && chown -R radicale:radicale /var/lib/radicale/collections`
|
||
as root.)
|
||
|
||
**Security:** The storage should not be readable by others.
|
||
(Run `chmod -R o= /var/lib/radicale/collections` as root.)
|
||
|
||
Create the file `/etc/systemd/system/radicale.service`:
|
||
```ini
|
||
[Unit]
|
||
Description=A simple CalDAV (calendar) and CardDAV (contact) server
|
||
After=network.target
|
||
Requires=network.target
|
||
|
||
[Service]
|
||
ExecStart=/usr/bin/env python3 -m radicale
|
||
Restart=on-failure
|
||
User=radicale
|
||
# Deny other users access to the calendar data
|
||
UMask=0027
|
||
# Optional security settings
|
||
PrivateTmp=true
|
||
ProtectSystem=strict
|
||
ProtectHome=true
|
||
PrivateDevices=true
|
||
ProtectKernelTunables=true
|
||
ProtectKernelModules=true
|
||
ProtectControlGroups=true
|
||
NoNewPrivileges=true
|
||
ReadWritePaths=/var/lib/radicale/collections
|
||
|
||
[Install]
|
||
WantedBy=multi-user.target
|
||
```
|
||
Radicale will load the configuration file from `/etc/radicale/config`.
|
||
|
||
To enable and manage the service run:
|
||
```bash
|
||
# Enable the service
|
||
$ systemctl enable radicale
|
||
# Start the service
|
||
$ systemctl start radicale
|
||
# Check the status of the service
|
||
$ systemctl status radicale
|
||
# View all log messages
|
||
$ journalctl --unit radicale.service
|
||
```
|
||
|
||
### MacOS with launchd
|
||
|
||
*To be written.*
|
||
|
||
### Classic daemonization
|
||
|
||
Set the configuration option `daemon` in the section `server` to `True`.
|
||
You may want to set the option `pid` to the path of a PID file.
|
||
|
||
After daemonization the server will not log anything. You have to configure
|
||
[Logging](#documentation/logging).
|
||
|
||
If you start Radicale now, it will initialize and fork into the background.
|
||
The main process exits, after the PID file is written.
|
||
|
||
**Security:** You can set the **umask** with `umask 0027` before you start the
|
||
daemon, to protect your calendar data and log files from other users.
|
||
Don't forget to set permissions of files that are already created!
|
||
|
||
|
||
### Windows with "NSSM - the Non-Sucking Service Manager"
|
||
|
||
First install [NSSM](https://nssm.cc/) and start `nssm install` in a command
|
||
prompt. Apply the following configuration:
|
||
|
||
* Service name: `Radicale`
|
||
* Application
|
||
* Path: `C:\Path\To\Python\python.exe`
|
||
* Arguments: `-m radicale --config C:\Path\To\Config`
|
||
* I/O redirection
|
||
* Error: `C:\Path\To\Radicale.log`
|
||
|
||
**Security:** Be aware that the service runs in the local system account,
|
||
you might want to change this. Managing user accounts is beyond the scope of
|
||
this manual. Also make sure that the storage folder and log file is not readable
|
||
by unauthorized users.
|
||
|
||
The log file might grow very big over time, you can configure file rotation
|
||
in **NSSM** to prevent this.
|
||
|
||
The service is configured to start automatically when the computer starts.
|
||
To start the service manually open **Services** in **Computer Management** and
|
||
start the **Radicale** service.
|
||
|
||
## Reverse Proxy
|
||
|
||
When a reverse proxy is used, the path at which Radicale is available must
|
||
be provided via the `X-Script-Name` header. The proxy must remove the location
|
||
from the URL path that is forwarded to Radicale.
|
||
|
||
Example **nginx** configuration:
|
||
```nginx
|
||
location /radicale/ { # The trailing / is important!
|
||
proxy_pass http://localhost:5232/; # The / is important!
|
||
proxy_set_header X-Script-Name /radicale;
|
||
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
|
||
proxy_pass_header Authorization;
|
||
}
|
||
```
|
||
|
||
Example **Apache** configuration:
|
||
```apache
|
||
RewriteEngine On
|
||
RewriteRule ^/radicale$ /radicale/ [R,L]
|
||
|
||
<Location "/radicale/">
|
||
ProxyPass http://localhost:5232/ retry=0
|
||
ProxyPassReverse http://localhost:5232/
|
||
RequestHeader set X-Script-Name /radicale/
|
||
</Location>
|
||
```
|
||
|
||
Be reminded that Radicale's default configuration enforces limits on the
|
||
maximum number of parallel connections, the maximum file size and the rate of
|
||
incorrect authentication attempts. Connections are terminated after a timeout.
|
||
|
||
### Manage user accounts with the reverse proxy
|
||
Set the configuration option `type` in the `auth` section to
|
||
`http_x_remote_user`.
|
||
Radicale uses the user name provided in the `X-Remote-User` HTTP header and
|
||
disables HTTP authentication.
|
||
|
||
Example **nginx** configuration:
|
||
|
||
```nginx
|
||
location /radicale/ {
|
||
proxy_pass http://localhost:5232/;
|
||
proxy_set_header X-Script-Name /radicale;
|
||
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
|
||
proxy_set_header X-Remote-User $remote_user;
|
||
auth_basic "Radicale - Password Required";
|
||
auth_basic_user_file /etc/nginx/htpasswd;
|
||
}
|
||
```
|
||
|
||
Example **Apache** configuration:
|
||
```apache
|
||
RewriteEngine On
|
||
RewriteRule ^/radicale$ /radicale/ [R,L]
|
||
|
||
<Location "/radicale/">
|
||
AuthType Basic
|
||
AuthName "Radicale - Password Required"
|
||
AuthUserFile "/etc/radicale/htpasswd"
|
||
Require valid-user
|
||
|
||
ProxyPass http://localhost:5232/ retry=0
|
||
ProxyPassReverse http://localhost:5232/
|
||
RequestHeader set X-Script-Name /radicale/
|
||
RequestHeader set X-Remote-User expr=%{REMOTE_USER}
|
||
</Location>
|
||
```
|
||
|
||
**Security:** Untrusted clients should not be able to access the Radicale
|
||
server directly. Otherwise, they can authenticate as any user.
|
||
|
||
### Secure connection between Radicale and the reverse proxy
|
||
SSL certificates can be used to encrypt and authenticate the connection between
|
||
Radicale and the reverse proxy. First you have to generate a certificate for
|
||
Radicale and a certificate for the reverse proxy. The following commands
|
||
generate self-signed certificates. You will be asked to enter additional
|
||
information about the certificate, the values don't matter and you can keep the
|
||
defaults.
|
||
|
||
```bash
|
||
$ openssl req -x509 -newkey rsa:4096 -keyout server_key.pem -out server_cert.pem -nodes -days 9999
|
||
$ openssl req -x509 -newkey rsa:4096 -keyout client_key.pem -out client_cert.pem -nodes -days 9999
|
||
```
|
||
|
||
Use the following configuration for Radicale:
|
||
|
||
```ini
|
||
[server]
|
||
ssl = True
|
||
certificate = /path/to/server_cert.pem
|
||
key = /path/to/server_key.pem
|
||
certificate_authority = /path/to/client_cert.pem
|
||
```
|
||
|
||
Example **nginx** configuration:
|
||
|
||
```nginx
|
||
location /radicale/ {
|
||
proxy_pass https://localhost:5232/;
|
||
...
|
||
# Place the files somewhere nginx is allowed to access (e.g. /etc/nginx/...).
|
||
proxy_ssl_certificate /path/to/client_cert.pem;
|
||
proxy_ssl_certificate_key /path/to/client_key.pem;
|
||
proxy_ssl_trusted_certificate /path/to/server_cert.pem;
|
||
}
|
||
```
|
||
|
||
## WSGI
|
||
|
||
Radicale is compatible with the WSGI specification.
|
||
|
||
A configuration file can be set with the `RADICALE_CONFIG` environment variable,
|
||
otherwise no configuration file is loaded and the default configuration is used.
|
||
|
||
Be reminded that Radicale's default configuration enforces limits on the
|
||
maximum upload file size.
|
||
|
||
**Security:** The `None` authentication type disables all rights checking.
|
||
Don't use it with `REMOTE_USER`. Use `remote_user` instead.
|
||
|
||
Example **uWSGI** configuration:
|
||
|
||
```ini
|
||
[uwsgi]
|
||
http-socket = 127.0.0.1:5232
|
||
processes = 8
|
||
plugin = python3
|
||
module = radicale
|
||
env = RADICALE_CONFIG=/etc/radicale/config
|
||
```
|
||
|
||
Example **Gunicorn** configuration:
|
||
|
||
```bash
|
||
gunicorn --bind '127.0.0.1:5232' --workers 8 --env 'RADICALE_CONFIG=/etc/radicale/config' radicale
|
||
```
|
||
|
||
### Manage user accounts with the WSGI server
|
||
Set the configuration option `type` in the `auth` section to `remote_user`.
|
||
Radicale uses the user name provided by the WSGI server and disables
|
||
authentication over HTTP.
|
||
|
||
## Versioning
|
||
|
||
This page describes how to keep track of all changes to calendars and
|
||
address books with **git** (or any other version control system).
|
||
|
||
The repository must be initialized by running `git init` in the file
|
||
system folder. Internal files of Radicale can be excluded by creating the
|
||
file `.gitignore` with the following content:
|
||
```
|
||
.Radicale.cache
|
||
.Radicale.lock
|
||
.Radicale.tmp-*
|
||
```
|
||
|
||
The configuration option `hook` in the `storage` section must be set to
|
||
the following command:
|
||
```bash
|
||
git add -A && (git diff --cached --quiet || git commit -m "Changes by "%(user)s)
|
||
```
|
||
|
||
The command gets executed after every change to the storage and commits
|
||
the changes into the **git** repository.
|
||
|
||
## Clients
|
||
|
||
Radicale has been tested with:
|
||
|
||
* [Android](https://android.com/) with
|
||
[DAVx⁵](https://www.davx5.com/) (formerly DAVdroid)
|
||
* [GNOME Calendar](https://wiki.gnome.org/Apps/Calendar),
|
||
[Contacts](https://wiki.gnome.org/Apps/Contacts) and
|
||
[Evolution](https://wiki.gnome.org/Apps/Evolution)
|
||
* [Mozilla Thunderbird](https://www.mozilla.org/thunderbird/) with
|
||
[CardBook](https://addons.mozilla.org/thunderbird/addon/cardbook/) and
|
||
[Lightning](https://www.mozilla.org/projects/calendar/)
|
||
* [InfCloud](https://www.inf-it.com/open-source/clients/infcloud/),
|
||
[CalDavZAP](https://www.inf-it.com/open-source/clients/caldavzap/) and
|
||
[CardDavMATE](https://www.inf-it.com/open-source/clients/carddavmate/)
|
||
|
||
Many clients do not support the creation of new calendars and address books.
|
||
You can use Radicale's web interface
|
||
(e.g. [http://localhost:5232](http://localhost:5232)) to create and manage
|
||
collections.
|
||
|
||
In some clients you can just enter the URL of the Radicale server
|
||
(e.g. `http://localhost:5232`) and your user name. In others, you have to
|
||
enter the URL of the collection directly
|
||
(e.g. `http://localhost:5232/user/calendar`).
|
||
|
||
### DAVx⁵
|
||
|
||
Enter the URL of the Radicale server (e.g. `http://localhost:5232`) and your
|
||
user name. DAVx⁵ will show all existing calendars and address books and you
|
||
can create new.
|
||
|
||
### GNOME Calendar, Contacts and Evolution
|
||
|
||
**GNOME Calendar** and **Contacts** do not support adding WebDAV calendars
|
||
and address books directly, but you can add them in **Evolution**.
|
||
|
||
In **Evolution** add a new calendar and address book respectively with WebDAV.
|
||
Enter the URL of the Radicale server (e.g. `http://localhost:5232`) and your
|
||
user name. Clicking on the search button will list the existing calendars and
|
||
address books.
|
||
|
||
### Thunderbird
|
||
|
||
#### CardBook
|
||
|
||
Add a new address book on the network with CardDAV. You have to enter the full
|
||
URL of the collection (e.g. `http://localhost:5232/user/addressbook`) and
|
||
your user name.
|
||
|
||
#### Lightning
|
||
|
||
Add a new calendar on the network with `CalDAV`. (Don't use `iCalendar (ICS)`!)
|
||
You have to enter the full URL of the collection (e.g.
|
||
`http://localhost:5232/user/calendar`). If you want to add calendars from
|
||
different users on the same server, you can specify the user name in the URL
|
||
(e.g. `http://user@localhost...`)
|
||
|
||
### InfCloud, CalDavZAP and CardDavMATE
|
||
|
||
You can integrate InfCloud into Radicale's web interface with
|
||
[RadicaleInfCloud](https://github.com/Unrud/RadicaleInfCloud). No additional
|
||
configuration is required.
|
||
|
||
Set the URL of the Radicale server in ``config.js``. If **InfCloud** is not
|
||
hosted on the same server and port as Radicale, the browser will deny access to
|
||
the Radicale server, because of the
|
||
[same-origin policy](https://en.wikipedia.org/wiki/Same-origin_policy).
|
||
You have to add additional HTTP header in the `headers` section of Radicale's
|
||
configuration. The documentation of **InfCloud** has more details on this.
|
||
|
||
### Manual creation of calendars and address books
|
||
|
||
This is not the recommended way of creating and managing your calendars and
|
||
address books. Use Radicale's web interface or a client with support for it
|
||
(e.g. **DAVx⁵**).
|
||
|
||
#### Direct editing of the storage
|
||
|
||
To create a new collection, you have to create the corresponding folder in the
|
||
file system storage (e.g. `collection-root/user/calendar`).
|
||
To tell Radicale and clients that the collection is a calendar, you have to
|
||
create the file ``.Radicale.props`` with the following content in the folder:
|
||
|
||
```json
|
||
{"tag": "VCALENDAR"}
|
||
```
|
||
|
||
The calendar is now available at the URL path ``/user/calendar``.
|
||
For address books the file must contain:
|
||
|
||
```json
|
||
{"tag": "VADDRESSBOOK"}
|
||
```
|
||
|
||
Calendar and address book collections must not have any child collections.
|
||
Clients with automatic discovery of collections will only show calendars and
|
||
addressbooks that are direct children of the path `/USERNAME/`.
|
||
|
||
Delete collections by deleting the corresponding folders.
|
||
|
||
#### HTTP requests with curl
|
||
|
||
To create a new calendar run something like:
|
||
|
||
```bash
|
||
$ curl -u user -X MKCOL 'http://localhost:5232/user/calendar' --data \
|
||
'<?xml version="1.0" encoding="UTF-8" ?>
|
||
<create xmlns="DAV:" xmlns:C="urn:ietf:params:xml:ns:caldav" xmlns:I="http://apple.com/ns/ical/">
|
||
<set>
|
||
<prop>
|
||
<resourcetype>
|
||
<collection />
|
||
<C:calendar />
|
||
</resourcetype>
|
||
<C:supported-calendar-component-set>
|
||
<C:comp name="VEVENT" />
|
||
<C:comp name="VJOURNAL" />
|
||
<C:comp name="VTODO" />
|
||
</C:supported-calendar-component-set>
|
||
<displayname>Calendar</displayname>
|
||
<C:calendar-description>Example calendar</C:calendar-description>
|
||
<I:calendar-color>#ff0000ff</I:calendar-color>
|
||
</prop>
|
||
</set>
|
||
</create>'
|
||
```
|
||
|
||
To create a new address book run something like:
|
||
|
||
```bash
|
||
$ curl -u user -X MKCOL 'http://localhost:5232/user/addressbook' --data \
|
||
'<?xml version="1.0" encoding="UTF-8" ?>
|
||
<create xmlns="DAV:" xmlns:CR="urn:ietf:params:xml:ns:carddav">
|
||
<set>
|
||
<prop>
|
||
<resourcetype>
|
||
<collection />
|
||
<CR:addressbook />
|
||
</resourcetype>
|
||
<displayname>Address book</displayname>
|
||
<CR:addressbook-description>Example address book</CR:addressbook-description>
|
||
</prop>
|
||
</set>
|
||
</create>'
|
||
```
|
||
|
||
The collection `/USERNAME` will be created automatically, when the user
|
||
authenticates to Radicale for the first time. Clients with automatic discovery
|
||
of collections will only show calendars and address books that are direct
|
||
children of the path `/USERNAME/`.
|
||
|
||
Delete the collections by running something like:
|
||
|
||
```bash
|
||
$ curl -u user -X DELETE 'http://localhost:5232/user/calendar'
|
||
```
|
||
|
||
## Configuration
|
||
|
||
Radicale can be configured with a configuration file or with
|
||
command line arguments.
|
||
|
||
An example configuration file looks like:
|
||
```ini
|
||
[server]
|
||
# Bind all addresses
|
||
hosts = 0.0.0.0:5232
|
||
|
||
[auth]
|
||
type = htpasswd
|
||
htpasswd_filename = /path/to/users
|
||
htpasswd_encryption = bcrypt
|
||
[storage]
|
||
filesystem_folder = ~/.var/lib/radicale/collections
|
||
```
|
||
|
||
Radicale tries to load configuration files from `/etc/radicale/config`,
|
||
`~/.config/radicale/config` and the `RADICALE_CONFIG` environment variable.
|
||
This behaviour can be overwritten by specifying a path with the
|
||
`--config /path/to/config` command line argument.
|
||
|
||
The same example configuration via command line arguments looks like:
|
||
```bash
|
||
python3 -m radicale --config "" --server-hosts 0.0.0.0:5232 --auth-type htpasswd --htpasswd-filename /path/to/htpasswd --htpasswd-encryption bcrypt
|
||
```
|
||
|
||
The `--config ""` argument is required to stop Radicale from trying
|
||
to load configuration files. Run `python3 -m radicale --help` for more information.
|
||
|
||
In the following, all configuration categories and options are described.
|
||
|
||
### server
|
||
Most configuration options in this category are only relevant in standalone
|
||
mode. All options beside `max_content_length` and `realm` are ignored,
|
||
when Radicale runs via WSGI.
|
||
|
||
#### hosts
|
||
A comma separated list of addresses that the server will bind to.
|
||
|
||
Default: `127.0.0.1:5232`
|
||
|
||
#### daemon
|
||
Daemonize the Radicale process. It does not reset the umask.
|
||
|
||
Default: `False`
|
||
|
||
#### pid
|
||
If daemon mode is enabled, Radicale will write its PID to this file.
|
||
|
||
Default:
|
||
|
||
#### max_connections
|
||
The maximum number of parallel connections. Set to `0` to disable the limit.
|
||
|
||
Default: `20`
|
||
|
||
#### max_content_length
|
||
The maximum size of the request body. (bytes)
|
||
|
||
Default: `100000000`
|
||
|
||
#### timeout
|
||
Socket timeout. (seconds)
|
||
|
||
Default: `30`
|
||
|
||
#### ssl
|
||
Enable transport layer encryption.
|
||
|
||
Default: `False`
|
||
|
||
#### certificate
|
||

|
||
|
||
Default: `/etc/ssl/radicale.cert.pem`
|
||
|
||
#### key
|
||
Path to the private key for SSL. Only effective if `ssl` is enabled.
|
||
|
||
Default: `/etc/ssl/radicale.key.pem`
|
||
|
||
#### certificate_authority
|
||
Path to the CA certificate for validating client certificates. This can be used
|
||
to secure TCP traffic between Radicale and a reverse proxy. If you want to
|
||
authenticate users with client-side certificates, you also have to write an
|
||
authentication plugin that extracts the user name from the certifcate.
|
||
|
||
Default:
|
||
|
||
#### protocol
|
||
SSL protocol used. See python's ssl module for available values.
|
||
|
||
Default: `PROTOCOL_TLSv1_2`
|
||
|
||
#### ciphers
|
||
Available ciphers for SSL. See python's ssl module for available ciphers.
|
||
|
||
Default:
|
||
|
||
#### dns_lookup
|
||
Reverse DNS to resolve client address in logs.
|
||
|
||
Default: `True`
|
||
|
||
#### realm
|
||
Message displayed in the client when a password is needed.
|
||
|
||
Default: `Radicale - Password Required`
|
||
|
||
### encoding

||
Encoding for responding requests.
|
||
|
||
Default: `utf-8`
|
||
|
||
#### stock
|
||
Encoding for storing local collections
|
||
|
||
Default: `utf-8`
|
||
|
||
### auth
|
||
#### type
|
||
The method to verify usernames and passwords.
|
||
|
||
Available backends:
|
||
|
||
`None`
|
||
: Just allows all usernames and passwords. It also disables rights checking.
|
||
|
||
`htpasswd`
|
||
: Use an [Apache htpasswd file](https://httpd.apache.org/docs/current/programs/htpasswd.html) to store
|
||
usernames and passwords.
|
||
|
||
`remote_user`
|
||
: Takes the user name from the `REMOTE_USER` environment variable and disables
|
||
HTTP authentication. This can be used to provide the user name from a WSGI
|
||
server.
|
||
|
||
`http_x_remote_user`
|
||
: Takes the user name from the `X-Remote-User` HTTP header and disables HTTP
|
||
authentication. This can be used to provide the user name from a reverse
|
||
proxy.
|
||
|
||
Default: `None`
|
||
|
||
#### htpasswd_filename
|
||
Path to the htpasswd file.
|
||
|
||
Default:
|
||
|
||
#### htpasswd_encryption
|
||
The encryption method that is used in the htpasswd file. Use the
|
||
[htpasswd](https://httpd.apache.org/docs/current/programs/htpasswd.html)
|
||
or similar to generate this files.
|
||
|
||
Available methods:
|
||
|
||
`plain`
|
||
: Passwords are stored in plaintext. This is obviously not secure!
|
||
The htpasswd file for this can be created by hand and looks like:
|
||
```htpasswd
|
||
user1:password1
|
||
user2:password2
|
||
```
|
||
|
||
`bcrypt`
|
||
: This uses a modified version of the Blowfish stream cipher. It's very secure.
|
||
The **passlib** python module is required for this. Additionally you may need
|
||
one of the following python modules: **bcrypt**, **py-bcrypt** or **bcryptor**.
|
||
|
||
`md5`
|
||
: This uses an iterated md5 digest of the password with a salt.
|
||
The **passlib** python module is required for this.
|
||
|
||
`sha1`
|
||
: Passwords are stored as SHA1 hashes. It's insecure!
|
||
|
||
`ssha`
|
||
: Passwords are stored as salted SHA1 hashes. It's insecure!
|
||
|
||
`crypt`
|
||
: This uses UNIX
|
||
[crypt(3)](https://manpages.debian.org/unstable/manpages-dev/crypt.3.en.html).
|
||
It's insecure!
|
||
|
||
Default: `bcrypt`
|
||
|
||
#### delay
|
||
Average delay after failed login attempts in seconds.
|
||
|
||
Default: `1`
|
||
|
||
### rights
|
||
#### type
|
||
The backend that is used to check the access rights of collections.
|
||
|
||
The recommended backend is `owner_only`. If access to calendars
|
||
and address books outside of the home directory of users (that's `/USERNAME/`)
|
||
is granted, clients won't detect these collections and will not show them to
|
||
the user. Choosing any other method is only useful if you access calendars and
|
||
address books directly via URL.
|
||
|
||
Available backends:
|
||
|
||
`None`
|
||
: Everyone can read and write everything.
|
||
|
||
`authenticated`
|
||
: Authenticated users can read and write everything.
|
||
|
||
`owner_only`
|
||
: Authenticated users can read and write their own collections under the path
|
||
*/USERNAME/*.
|
||
|
||
`owner_write`
|
||
: Authenticated users can read everything and write their own collections under
|
||
the path */USERNAME/*.
|
||
|
||
`from_file`
|
||
: Load the rules from a file.
|
||
|
||
Default: `owner_only`
|
||
|
||
#### file
|
||
File for the rights backend `from_file`. See the
|
||
[Rights](#documentation/authentication-and-rights) page.
|
||
|
||
### storage
|
||
#### type
|
||
The backend that is used to store data.
|
||
|
||
Available backends:
|
||
|
||
`multifilesystem`
|
||
: Stores the data in the filesystem.
|
||
|
||
Default: `multifilesystem`
|
||
|
||
#### filesystem_folder
|
||
|
||
Folder for storing local collections, created if not present.
|
||
|
||
Default: `/var/lib/radicale/collections`
|
||
|
||
#### filesystem_locking
|
||
Lock the storage. This must be disabled if locking is not supported by the
|
||
underlying file system. Never start multiple instances of Radicale or edit the
|
||
storage externally while Radicale is running if disabled.
|
||
|
||
Default: `True`
|
||
|
||
#### max_sync_token_age
|
||
Delete sync-token that are older than the specified time. (seconds)
|
||
|
||
Default: `2592000`
|
||
|
||
#### filesystem_fsync
|
||
Sync all changes to disk during requests. (This can impair performance.)
|
||
Disabling it increases the risk of data loss, when the system crashes or
|
||
power fails!
|
||
|
||
Default: `True`
|
||
|
||
#### hook
|
||
Command that is run after changes to storage. Take a look at the
|
||
[Versioning](#documentation/versioning) page for an example.
|
||
|
||
Default:
|
||
|
||
### web
|
||
#### type
|
||
The backend that provides the web interface of Radicale.
|
||
|
||
Available backends:
|
||
|
||
`none`
|
||
: Just shows the message "Radicale works!".
|
||
|
||
`internal`
|
||
: Allows creation and management of address books and calendars.
|
||
|
||
Default: `internal`
|
||
|
||
### logging
|
||
#### debug
|
||
Set the default logging level to debug.
|
||
|
||
Default: `False`
|
||
|
||
#### full_environment
|
||
Log all environment variables (including those set in the shell).
|
||
|
||
Default: `False`
|
||
|
||
#### mask_passwords
|
||
Don't include passwords in logs.
|
||
|
||
Default: `True`
|
||
|
||
#### config
|
||
Logging configuration file. See the [Logging](#documentation/logging) page.
|
||
|
||
Default:
|
||
|
||
### headers
|
||
In this section additional HTTP headers that are sent to clients can be
|
||
specified.
|
||
|
||
An example to relax the same-origin policy:
|
||
```ini
|
||
Access-Control-Allow-Origin = *
|
||
```
|
||
|
||
## Authentication and Rights
|
||
|
||
This page describes the format of the rights file for the `from_file`
|
||
authentication backend. The configuration option `file` in the `rights`
|
||
section must point to the rights file.
|
||
|
||
The recommended rights method is `owner_only`. If access to calendars
|
||
and address books outside of the home directory of users (that's `/USERNAME/`)
|
||
is granted, clients won't detect these collections and will not show them to
|
||
the user.
|
||
This is only useful if you access calendars and address books directly via URL.
|
||
|
||
An example rights file:
|
||
```ini
|
||
# The user "admin" can read and write any collection.
|
||
[admin]
|
||
user = admin
|
||
collection = .*
|
||
permission = rw
|
||
|
||
# Block access for the user "user" to everything.
|
||
[block]
|
||
user = user
|
||
collection = .*
|
||
permission =
|
||
|
||
# Authenticated users can read and write their own collections.
|
||
[owner-write]
|
||
user = .+
|
||
collection = %(login)s(/.*)?
|
||
permission = rw
|
||
|
||
# Everyone can read the root collection
|
||
[read]
|
||
user = .*
|
||
collection =
|
||
permission = r
|
||
```
|
||
|
||
The titles of the sections are ignored (but must be unique). The keys `user`
|
||
and `collection` contain regular expressions, that are matched against the
|
||
user name and the path of the collection. Permissions from the first
|
||
matching section are used. If no section matches, access gets denied.
|
||
|
||
The user name is empty for anonymous users. Therefore, the regex `.+` only
|
||
matches authenticated users and `.*` matches everyone (including anonymous
|
||
users).
|
||
|
||
The path of the collection is separated by `/` and has no leading or trailing
|
||
`/`. Therefore, the path of the root collection is empty.
|
||
|
||
`%(login)s` gets replaced by the user name and `%(path)s` by the path of
|
||
the collection. You can also get groups from the `user` regex in the
|
||
`collection` regex with `{0}`, `{1}`, etc.
|
||
|
||
## Storage
|
||
|
||
This document describes the layout and format of the file system storage
|
||
(`multifilesystem` backend).
|
||
|
||
It's safe to access and manipulate the data by hand or with scripts.
|
||
Scripts can be invoked manually, periodically (e.g. with
|
||
[cron](https://manpages.debian.org/unstable/cron/cron.8.en.html)) or after each
|
||
change to the storage with the configuration option `hook` in the `storage`
|
||
section (e.g. [Git Versioning](#documentation/versioning)).
|
||
|
||
### Layout
|
||
|
||
The file system contains the following files and folders:
|
||
|
||
* `.Radicale.lock`: The lock file for locking the storage.
|
||
* `collection-root`: This folder contains all collections and items.
|
||
|
||
A collection is represented by a folder. This folder may contain the file
|
||
`.Radicale.props` with all WebDAV properties of the collection encoded
|
||
as [JSON](https://en.wikipedia.org/wiki/JSON).
|
||
|
||
An item is represented by a file containing the iCalendar data.
|
||
|
||
All files and folders, whose names start with a dot but not `.Radicale.`
|
||
(internal files) are ignored.
|
||
|
||
If you introduce syntax errors in any of the files, all requests that access
|
||
the faulty data will fail. The logging output should contain the names of the
|
||
culprits.
|
||
|
||
Future releases of Radicale 2.x.x will store caches and sync-tokens in the
|
||
`.Radicale.cache` folder inside of collections.
|
||
This folder may be created or modified, while the storage is locked for shared
|
||
access.
|
||
In theory, it should be safe to delete the folder. Caches will be recreated
|
||
automatically and clients will be told that their sync-token isn't valid
|
||
anymore.
|
||
|
||
You may encounter files or folders that start with `.Radicale.tmp-`.
|
||
Radicale uses them for atomic creation and deletion of files and folders.
|
||
They should be deleted after requests are finished but it's possible that
|
||
they are left behind when Radicale or the computer crashes.
|
||
It's safe to delete them.
|
||
|
||
### Locking
|
||
|
||
When the data is accessed by hand or by an externally invoked script,
|
||
the storage must be locked. The storage can be locked for exclusive or
|
||
shared access. It prevents Radicale from reading or writing the file system.
|
||
The storage is locked with exclusive access while the `hook` runs.
|
||
|
||
#### Linux shell scripts
|
||
|
||
Use the
|
||
[flock](https://manpages.debian.org/unstable/util-linux/flock.1.en.html)
|
||
utility.
|
||
|
||
```bash
|
||
# Exclusive
|
||
$ flock --exclusive /path/to/storage/.Radicale.lock COMMAND
|
||
# Shared
|
||
$ flock --shared /path/to/storage/.Radicale.lock COMMAND
|
||
```
|
||
|
||
#### Linux and MacOS
|
||
|
||
Use the
|
||
[flock](https://manpages.debian.org/unstable/manpages-dev/flock.2.en.html)
|
||
syscall. Python provides it in the
|
||
[fcntl](https://docs.python.org/3/library/fcntl.html#fcntl.flock) module.
|
||
|
||
#### Windows
|
||
Use
|
||
[LockFile](https://msdn.microsoft.com/en-us/library/windows/desktop/aa365202%28v=vs.85%29.aspx)
|
||
for exclusive access or
|
||
[LockFileEx](https://msdn.microsoft.com/en-us/library/windows/desktop/aa365203%28v=vs.85%29.aspx)
|
||
which also supports shared access. Setting `nNumberOfBytesToLockLow` to `1`
|
||
and `nNumberOfBytesToLockHigh` to `0` works.
|
||
|
||
## Logging
|
||
|
||
Radicale logs to `stderr`. The verbosity of the log output can be controlled
|
||
with `--debug` command line argument or the `debug` configuration option in
|
||
the `logging` section.
|
||
|
||
This is the recommended configuration for use with modern init systems
|
||
(like **systemd**) or if you just test Radicale in a terminal.
|
||
|
||
You can configure Radicale to write its logging output to files (and even
|
||
rotate them).
|
||
This is useful if the process daemonizes or if your chosen method of running
|
||
Radicale doesn't handle logging output.
|
||
|
||
A logging configuration file can be specified in the `config` configuration
|
||
option in the `logging` section. The file format is explained in the
|
||
[Python Logging Module](https://docs.python.org/3/library/logging.config.html#configuration-file-format).
|
||
|
||
### Logging to a file
|
||
|
||
An example configuration to write the log output to the file `/var/log/radicale/log`:
|
||
```ini
|
||
[loggers]
|
||
keys = root
|
||
|
||
[handlers]
|
||
keys = file
|
||
|
||
[formatters]
|
||
keys = full
|
||
|
||
[logger_root]
|
||
# Change this to DEBUG or INFO for higher verbosity.
|
||
level = WARNING
|
||
handlers = file
|
||
|
||
[handler_file]
|
||
class = FileHandler
|
||
# Specify the output file here.
|
||
args = ('/var/log/radicale/log',)
|
||
formatter = full
|
||
|
||
[formatter_full]
|
||
format = %(asctime)s - [%(thread)x] %(levelname)s: %(message)s
|
||
```
|
||
|
||
You can specify multiple **logger**, **handler** and **formatter** if you want
|
||
to have multiple simultaneous log outputs.
|
||
|
||
The parent folder of the log files must exist and must be writable by Radicale.
|
||
|
||
**Security:** The log files should not be readable by unauthorized users. Set
|
||
permissions accordingly.
|
||
|
||
#### Timed rotation of disk log files
|
||
|
||
An example **handler** configuration to write the log output to the file `/var/log/radicale/log` and rotate it.
|
||
Replace the section `handler_file` from the file logging example:
|
||
```ini
|
||
[handler_file]
|
||
class = handlers.TimedRotatingFileHandler
|
||
# Specify the output file and parameter for rotation here.
|
||
# See https://docs.python.org/3/library/logging.handlers.html#logging.handlers.TimedRotatingFileHandler
|
||
# Example: rollover at midnight and keep 7 files (means one week)
|
||
args = ('/var/log/radicale/log', 'midnight', 1, 7)
|
||
formatter = full
|
||
```
|
||
|
||
#### Rotation of disk log files based on size
|
||
|
||
An example **handler** configuration to write the log output to the file `/var/log/radicale/log` and rotate it .
|
||
Replace the section `handle_file` from the file logging example:
|
||
```ini
|
||
[handler_file]
|
||
class = handlers.RotatingFileHandler
|
||
# Specify the output file and parameter for rotation here.
|
||
# See https://docs.python.org/3/library/logging.handlers.html#logging.handlers.RotatingFileHandler
|
||
# Example: rollover at 100000 kB and keep 10 files (means 1 MB)
|
||
args = ('/var/log/radicale/log', 'a', 100000, 10)
|
||
formatter = full
|
||
```
|
||
|
||
## Architecture
|
||
|
||
Radicale is a really small piece of software, but understanding it is not as
|
||
easy as it seems. But don't worry, reading this short page is enough to
|
||
understand what a CalDAV/CardDAV server is, and how Radicale's code is
|
||
organized.
|
||
|
||
|
||
### General Architecture
|
||
|
||
Here is a simple overview of the global architecture for reaching a calendar or
|
||
an address book through network:
|
||
|
||
<table>
|
||
<thead>
|
||
<tr>
|
||
<th>Part</th>
|
||
<th>Layer</th>
|
||
<th>Protocol or Format</th>
|
||
</tr>
|
||
</thead>
|
||
<tbody>
|
||
<tr>
|
||
<td rowspan="2">Server</td>
|
||
<td>Calendar/Contact Storage</td>
|
||
<td>iCal/vCard</td>
|
||
</tr>
|
||
<tr>
|
||
<td>Calendar/Contact Server</td>
|
||
<td>CalDAV/CardDAV Server</td>
|
||
</tr>
|
||
<tr>
|
||
<td>Transfer</td>
|
||
<td>Network</td>
|
||
<td>CalDAV/CardDAV (HTTP + TLS)</td>
|
||
</tr>
|
||
<tr>
|
||
<td rowspan="2">Client</td>
|
||
<td>Calendar/Contact Client</td>
|
||
<td>CalDAV/CardDAV Client</td>
|
||
</tr>
|
||
<tr>
|
||
<td>GUI</td>
|
||
<td>Terminal, GTK, Web interface, etc.</td>
|
||
</tr>
|
||
</tbody>
|
||
</table>
|
||
|
||
Radicale is **only the server part** of this architecture.
|
||
|
||
Please note that:
|
||
|
||
- CalDAV and CardDAV are superset protocols of WebDAV,
|
||
- WebDAV is a superset protocol of HTTP.
|
||
|
||
Radicale being a CalDAV/CardDAV server, it also can be seen as a special WebDAV
|
||
and HTTP server.
|
||
|
||
Radicale is **not the client part** of this architecture. It means that
|
||
Radicale never draws calendars, address books, events and contacts on the
|
||
screen. It only stores them and give the possibility to share them online with
|
||
other people.
|
||
|
||
If you want to see or edit your events and your contacts, you have to use
|
||
another software called a client, that can be a "normal" applications with
|
||
icons and buttons, a terminal or another web application.
|
||
|
||
|
||
### Code Architecture
|
||
|
||
The ``radicale`` package offers 9 modules.
|
||
|
||
`__main__`
|
||
: The main module provides a simple function called run. Its main work is to
|
||
read the configuration from the configuration file and from the options given
|
||
in the command line; then it creates a server, according to the configuration.
|
||
|
||
`__init__`
|
||
: This is the core part of the module, with the code for the CalDAV/CardDAV
|
||
server. The server inherits from a WSGIServer server class, which relies on
|
||
the default HTTP server class given by Python. The code managing the
|
||
different HTTP requests according to the CalDAV/CardDAV normalization is
|
||
written here.
|
||
|
||
`config`
|
||
: This part gives a dict-like access to the server configuration, read from the
|
||
configuration file. The configuration can be altered when launching the
|
||
executable with some command line options.
|
||
|
||
`xmlutils`
|
||
: The functions defined in this module are mainly called by the CalDAV/CardDAV
|
||
server class to read the XML part of the request, read or alter the
|
||
calendars, and create the XML part of the response. The main part of this
|
||
code relies on ElementTree.
|
||
|
||
`log`
|
||
: The start function provided by this module starts a logging mechanism based
|
||
on the default Python logging module. Logging options can be stored in a
|
||
logging configuration file.
|
||
|
||
`auth`
|
||
: This module provides a default authentication manager equivalent to Apache's
|
||
htpasswd. Login + password couples are stored in a file and used to
|
||
authenticate users. Passwords can be encrypted using various methods. Other
|
||
authentication methods can inherit from the base class in this file and be
|
||
provided as plugins.
|
||
|
||
`rights`
|
||
: This module is a set of Access Control Lists, a set of methods used by
|
||
Radicale to manage rights to access the calendars. When the CalDAV/CardDAV
|
||
server is launched, an Access Control List is chosen in the set, according to
|
||
the configuration. The HTTP requests are then filtered to restrict the access
|
||
depending on who is authenticated. Other configurations can be written using
|
||
regex-based rules. Other rights managers can also inherit from the base class
|
||
in this file and be provided as plugins.
|
||
|
||
`storage`
|
||
: In this module are written the classes representing collections and items in
|
||
Radicale, and the class storing these collections and items in your
|
||
filesystem. Other storage classes can inherit from the base class in this
|
||
file and be provided as plugins.
|
||
|
||
`web`
|
||
: This module contains the web interface.
|
||
|
||
## Plugins
|
||
|
||
Radicale can be extended by plugins for authentication, rights management and
|
||
storage. Plugins are **python** modules.
|
||
|
||
### Getting started
|
||
|
||
To get started we walk through the creation of a simple authentication
|
||
plugin, that accepts login attempts if the username and password are equal.
|
||
|
||
The easiest way to develop and install **python** modules is
|
||
[Distutils](https://docs.python.org/3/distutils/setupscript.html).
|
||
For a minimal setup create the file `setup.py` with the following content
|
||
in an empty folder:
|
||
|
||
```python
|
||
#!/usr/bin/env python3
|
||
|
||
from distutils.core import setup
|
||
|
||
setup(name="radicale_silly_auth", packages=["radicale_silly_auth"])
|
||
```
|
||
|
||
In the same folder create the sub-folder `radicale_silly_auth`. The folder
|
||
must have the same name as specified in `packages` above.
|
||
|
||
Create the file `__init__.py` in the `radicale_silly_auth` folder with the
|
||
following content:
|
||
|
||
```python
|
||
from radicale.auth import BaseAuth
|
||
|
||
|
||
class Auth(BaseAuth):
|
||
def is_authenticated(self, user, password):
|
||
# Example custom configuration option
|
||
foo = ""
|
||
if self.configuration.has_option("auth", "foo"):
|
||
foo = self.configuration.get("auth", "foo")
|
||
self.logger.info("Configuration option %r is %r", "foo", foo)
|
||
|
||
# Check authentication
|
||
self.logger.info("Login attempt by %r with password %r",
|
||
user, password)
|
||
return user == password
|
||
```
|
||
|
||
Install the python module by running the following command in the same folder
|
||
as `setup.py`:
|
||
```bash
|
||
python3 -m pip install --upgrade .
|
||
```
|
||
|
||
To make use this great creation in Radicale, set the configuration option
|
||
`type` in the `auth` section to `radicale_silly_auth`:
|
||
|
||
```ini
|
||
[auth]
|
||
type = radicale_silly_auth
|
||
foo = bar
|
||
```
|
||
|
||
You can uninstall the module with:
|
||
```bash
|
||
python3 -m pip uninstall radicale_silly_auth
|
||
```
|
||
|
||
### Authentication plugins
|
||
This plugin type is used to check login credentials.
|
||
The module must contain a class `Auth` that extends
|
||
`radicale.auth.BaseAuth`. Take a look at the file `radicale/auth.py` in
|
||
Radicale's source code for more information.
|
||
|
||
### Rights management plugins
|
||
This plugin type is used to check if a user has access to a path.
|
||
The module must contain a class `Rights` that extends
|
||
`radicale.rights.BaseRights`. Take a look at the file `radicale/rights.py` in
|
||
Radicale's source code for more information.
|
||
|
||
### Web plugins
|
||
This plugin type is used to provide the web interface for Radicale.
|
||
The module must contain a class `Web` that extends
|
||
`radicale.web.BaseWeb`. Take a look at the file `radicale/web.py` in
|
||
Radicale's source code for more information.
|
||
|
||
### Storage plugins
|
||
This plugin is used to store collections and items.
|
||
The module must contain a class `Collection` that extends
|
||
`radicale.storage.BaseCollection`. Take a look at the file `radicale/storage.py`
|
||
in Radicale's source code for more information.
|
||
|
||
## Migration from 1.x.x to 2.x.x
|
||
|
||
### Why a Migration?
|
||
|
||
Radicale 2.x.x is different from 1.x.x, here's everything you need to know about
|
||
this! **Please read this page carefully if you want to update Radicale.**
|
||
|
||
You'll also find extra information
|
||
in [issue #372](https://github.com/Kozea/Radicale/issues/372).
|
||
|
||
#### Python 3 Only
|
||
|
||
Radicale 2.x.x works with Python >= 3.3, and **doesn't work anymore with
|
||
Python 2**.
|
||
|
||
(No, Python 3.3 is not new, it's been released more than 4 years ago.
|
||
Debian stable provides Python 3.4.)
|
||
|
||
#### Dependencies
|
||
|
||
Radicale now depends on [VObject](https://eventable.github.io/vobject/), a
|
||
"full-featured Python package for parsing and creating iCalendar and vCard
|
||
files". That's the price to pay to correctly read crazy iCalendar files and
|
||
**support date-based filters, even on recurring events**.
|
||
|
||
#### Storage
|
||
|
||
Calendars and address books are stored in a different way between 1.x.x and 2.x.x
|
||
versions. **Launching 2.x.x without migrating your collections first will not
|
||
work, Radicale won't be able to read your previous data.**
|
||
|
||
There's now only one way to store data in Radicale: collections are stored as
|
||
folders and events / contacts are stored in files. This new storage is close to
|
||
the `multifilesystem`, but **it's now thread-safe, with atomic writes and file
|
||
locks**. Other storage types can be used by creating
|
||
[plugins](#documentation/plugins).
|
||
|
||
To migrate data to Radicale 2.x.x the command line argument
|
||
``--export-storage`` was added to Radicale 1.1.x.
|
||
Start Radicale 1.x.x as you would normally do, but add the argument
|
||
``--export-storage path/to/empty/folder``. Radicale will export the storage
|
||
into the specified folder. This folder can be directly used with the
|
||
default storage backend of Radicale 2.x.x.
|
||
|
||
If you import big calendars or address books into Radicale 2.x.x the first
|
||
request might take a long time, because it has to initialize its internal
|
||
caches. Clients can time out, subsequent requests will be much faster.
|
||
|
||
You can check the imported storage for errors by starting Radicale >= 2.1.5
|
||
with the ``--verify-storage`` argument.
|
||
|
||
You can install version 1.1.6 with:
|
||
|
||
```bash
|
||
$ python3 -m pip install --upgrade radicale==1.1.6
|
||
```
|
||
|
||
#### Authentication
|
||
|
||
**Radicale 2.x.x only provides htpasswd authentication out-of-the-box.** Other
|
||
authentication methods can be added by creating or using
|
||
[plugins](#documentation/plugins).
|
||
|
||
#### Rights
|
||
|
||
In Radicale 2.x.x, rights are managed using regex-based rules based on the
|
||
login of the authenticated user and the URL of the resource. Default
|
||
configurations are built in for common cases, you'll find more about this on
|
||
the [Authentication & Rights](#documentation/authentication-and-rights) page.
|
||
|
||
Other rights managers can be added by creating
|
||
[plugins](#documentation/plugins).
|
||
|
||
#### Versioning
|
||
|
||
Support for versioning with **git** was removed from Radicale 2.x.x.
|
||
Instead, the configuration option ``hook`` in the ``storage`` section was added,
|
||
the [Collection Versioning](#documentation/versioning) page explains its
|
||
usage for version control.

# About
|
||
|
||
### Main Goals
|
||
|
||
Radicale is a complete calendar and contact storing and manipulating
|
||
solution. It can store multiple calendars and multiple address books.
|
||
|
||
Calendar and contact manipulation is available from both local and distant
|
||
accesses, possibly limited through authentication policies.
|
||
|
||
It aims to be a lightweight solution, easy to use, easy to install, easy to
|
||
configure. As a consequence, it requires few software dependencies and is
|
||
pre-configured to work out-of-the-box.
|
||
|
||
Radicale is written in Python. It runs on most of the UNIX-like platforms
|
||
(Linux, \*BSD, macOS) and Windows. It is free and open-source software.
|
||
|
||
### What Radicale Will Never Be
|
||
|
||
Radicale is a server, not a client. No interfaces will be created to work with
|
||
the server, as it is a really (really really) much more difficult task.
|
||
|
||
CalDAV and CardDAV are not perfect protocols. We think that their main problem
|
||
is their complexity, that is why we decided not to implement the whole standard
|
||
but just enough to understand some of its client-side implementations.
|
||
|
||
CalDAV and CardDAV are the best open standards available and they are quite
|
||
widely used by both clients and servers. We decided to use it, and we will not
|
||
use another one.
|
||
|
||
### Technical Choices
|
||
|
||
Important global development choices have been decided before writing
|
||
code. They are very useful to understand why the Radicale Project is different
|
||
from other CalDAV and CardDAV servers, and why features are included or not in
|
||
the code.
|
||
|
||
#### Oriented to Calendar and Contact User Agents
|
||
|
||
Calendar and contact servers work with calendar and contact clients, using a
|
||
defined protocol. CalDAV and CardDAV are good protocols, covering lots of
|
||
features and use cases, but it is quite hard to implement fully.
|
||
|
||
Some calendar servers have been created to follow the CalDAV and CardDAV RFCs
|
||
as much as possible: [Davical](http://www.davical.org/),
|
||
[Baïkal](http://sabre.io/baikal/) and
|
||
[Darwin Calendar Server](http://trac.calendarserver.org/), for example, are
|
||
much more respectful of CalDAV and CardDAV and can be used with a large number
|
||
of clients. They are very good choices if you want to develop and test new
|
||
CalDAV clients, or if you have a possibly heterogeneous list of user agents.
|
||
|
||
Even if it tries it best to follow the RFCs, Radicale does not and **will not**
|
||
blindly implements the CalDAV and CardDAV standards. It is mainly designed to
|
||
support the CalDAV and CardDAV implementations of different clients.
|
||
|
||
#### Simple
|
||
|
||
Radicale is designed to be simple to install, simple to configure, simple to
|
||
use.
|
||
|
||
The installation is very easy, particularly with Linux: one dependency, no
|
||
superuser rights needed, no configuration required, no database. Installing and
|
||
launching the main script out-of-the-box, as a normal user, are often the only
|
||
steps to have a simple remote calendar and contact access.
|
||
|
||
Contrary to other servers that are often complicated, require high privileges
|
||
or need a strong configuration, the Radicale Server can (sometimes, if not
|
||
often) be launched in a couple of minutes, if you follow the
|
||
[tutorial](#documentation/tutorial).
|
||
|
||
#### Lazy
|
||
|
||
The CalDAV RFC defines what must be done, what can be done and what cannot be
|
||
done. Many violations of the protocol are totally defined and behaviours are
|
||
given in such cases.
|
||
|
||
Radicale often assumes that the clients are perfect and that protocol
|
||
violations do not exist. That is why most of the errors in client requests have
|
||
undetermined consequences for the lazy server that can reply good answers, bad
|
||
answers, or even no answer.
|
||
|
||
### History
|
||
|
||
Radicale has been started as a (free topic) stupid school project replacing
|
||
another (assigned topic) even more stupid school project.
|
||
|
||
At the beginning, it was just a proof-of-concept. The main goal was to write a
|
||
small, dirty and simple CalDAV server working with Lightning, using no external
|
||
libraries. That's how we created a piece of code that's (quite) easy to
|
||
understand, to use and to hack.
|
||
|
||
The [first lines](https://github.com/Kozea/Radicale/commit/b1591aea) have been
|
||
added to the SVN (!) repository as I was drinking (many) beers at the very end
|
||
of 2008 (Python 2.6 and 3.0 were just released). It's now packaged for a
|
||
growing number of Linux distributions.
|
||
|
||
And that was fun going from here to there thanks to you!

|
||
This release concludes endless months of hard work from the community. You, all
|
||
users and contributors, deserve a big **thank you**.
|
||
|
||
This project has been an increadible experience for me, your dear Guillaume,
|
||
creator and maintainer of Radicale. After more than 8 years of fun, I think
|
||
that it's time to open this software to its contributors. Radicale can grow and
|
||
become more than the toy it used to be. I've always seen Radicale as a small
|
||
and simple piece of code, and I don't want to prevent people from adding
|
||
features just because I can't or don't want to maintain them. The community is
|
||
now large enough to handle this.
|
||
|
||
If you're interested in Radicale, you can
|
||
read [#372](https://github.com/Kozea/Radicale/issues/372) and build its
|
||
future.
|
||
|
||
## May 3, 2017 - Radicale 1.1.2
|
||
|
||
Radicale 1.1.2 is out!
|
||
|
||
|
||
### 1.1.2 - Third Law of Nature
|
||
|
||
* **Security fix**: Add a random timer to avoid timing oracles and simple
|
||
bruteforce attacks when using the htpasswd authentication method.
|
||
* Various minor fixes.
|
||
|
||
## December 31, 2015 - Radicale 1.1
|
||
|
||
Radicale 1.1 is out!
|
||
|
||
|
||
### 1.1 - Law of Nature
|
||
|
||
One feature in this release is **not backward compatible**:
|
||
|
||
* Use the first matching section for rights (inspired from daald)
|
||
|
||
Now, the first section matching the path and current user in your custom rights
|
||
file is used. In the previous versions, the most permissive rights of all the
|
||
matching sections were applied. This new behaviour gives a simple way to make
|
||
specific rules at the top of the file independant from the generic ones.
|
||
|
||
Many **improvements in this release are related to security**, you should
|
||
upgrade Radicale as soon as possible:
|
||
|
||
* Improve the regex used for well-known URIs (by Unrud)
|
||
* Prevent regex injection in rights management (by Unrud)
|
||
* Prevent crafted HTTP request from calling arbitrary functions (by Unrud)
|
||
* Improve URI sanitation and conversion to filesystem path (by Unrud)
|
||
* Decouple the daemon from its parent environment (by Unrud)
|
||
|
||
Some bugs have been fixed and little enhancements have been added:
|
||
|
||
* Assign new items to corret key (by Unrud)
|
||
* Avoid race condition in PID file creation (by Unrud)
|
||
* Improve the docker version (by cdpb)
|
||
* Encode message and commiter for git commits
|
||
* Test with Python 3.5
|
||
|
||
## September 14, 2015 - Radicale 1.0, what's next?
|
||
|
||
Radicale 1.0 is out!
|
||
|
||
### 1.0 - Sunflower
|
||
|
||
* Enhanced performances (by Mathieu Dupuy)
|
||
* Add MD5-APR1 and BCRYPT for htpasswd-based authentication (by Jan-Philip Gehrcke)
|
||
* Use PAM service (by Stephen Paul Weber)
|
||
* Don't discard PROPPATCH on empty collections (Markus Unterwaditzer)
|
||
* Write the path of the collection in the git message (Matthew Monaco)
|
||
* Tests launched on Travis
|
||
|
||
As explained in a previous [mail](http://librelist.com/browser//radicale/2015/8/21/radicale-1-0-is-coming-what-s-next/),
|
||
this version is called 1.0 because:
|
||
|
||
- there are no big changes since 0.10 but some small changes are really useful,
|
||
- simple tests are now automatically launched on Travis, and more can be added
|
||
in the future (https://travis-ci.org/Kozea/Radicale).
|
||
|
||
This version will be maintained with only simple bug fixes on a separate git
|
||
branch called ``1.0.x``.
|
||
|
||
Now that this milestone is reached, it's time to think about the future. When
|
||
Radicale has been created, it was just a proof-of-concept. The main goal was to
|
||
write a small, stupid and simple CalDAV server working with Lightning, using no
|
||
external libraries. That's how we created a piece of code that's (quite) easy
|
||
to understand, to use and to hack.
|
||
|
||
The first lines have been added to the SVN (!) repository as I was drinking
|
||
beers at the very end of 2008. It's now packaged for a growing number of Linux
|
||
distributions.
|
||
|
||
And that was fun going from here to there thanks to you. So… **Thank you,
|
||
you're amazing**. I'm so glad I've spent endless hours fixing stupid bugs,
|
||
arguing about databases and meeting invitations, reading incredibly interesting
|
||
RFCs and debugging with the fabulous clients from Apple. I mean: that really,
|
||
really was really, really cool :).
|
||
|
||
During these years, a lot of things have changed and many users now rely on
|
||
Radicale in production. For example, I use it to manage medical calendars, with
|
||
thousands requests per day. Many people are happy to install Radicale on their
|
||
small home servers, but are also frustrated by performance and unsupported
|
||
specifications when they're trying to use it seriously.
|
||
|
||
So, now is THE FUTURE! I think that Radicale 2.0 should:
|
||
|
||
- rely on a few external libraries for simple critical points (dealing with
|
||
HTTP and iCal for example),
|
||
- be thread-safe,
|
||
- be small,
|
||
- be documented in a different way (for example by splitting the client part
|
||
from the server part, and by adding use cases),
|
||
- let most of the "auth" modules outside in external modules,
|
||
- have more and more tests,
|
||
- have reliable and faster filesystem and database storage mechanisms,
|
||
- get a new design :).
|
||
|
||
I'd also secretly love to drop the Python 2.x support.
|
||
|
||
These ideas are not all mine (except from the really, really, really important
|
||
"design" point :p), they have been proposed by many developers and users. I've
|
||
just tried to gather them and keep points that seem important to me.
|
||
|
||
Other points have been discussed with many users and contibutors, including:
|
||
|
||
- support of other clients, including Windows and BlackBerry phones,
|
||
- server-side meeting invitations,
|
||
- different storage system as default (or even unique?).
|
||
|
||
I'm not a huge fan of these features, either because I can't do anything about
|
||
them, or because I think that they're Really Bad Ideas®™. But I'm ready to talk
|
||
about them, because, well, I may not be always right!
|
||
|
||

## January 12, 2015 - Radicale 0.10
|
||
|
||
Radicale 0.10 is out!
|
||
|
||
|
||
### 0.10 - Lovely Endless Grass
|
||
|
||
* Support well-known URLs (by Mathieu Dupuy)
|
||
* Fix collection discovery (by Markus Unterwaditzer)
|
||
* Reload logger config on SIGHUP (by Élie Bouttier)
|
||
* Remove props files when deleting a collection (by Vincent Untz)
|
||
* Support salted SHA1 passwords (by Marc Kleine-Budde)
|
||
* Don't spam the logs about non-SSL IMAP connections to localhost (by Giel van Schijndel)
|
||
|
||
This version should bring some interesting discovery and auto-configuration
|
||
features, mostly with Apple clients.
|
||
|
||
Lots of love and kudos for the people who have spent hours to test features and
|
||
report issues, that was long but really useful (and some of you have been
|
||
really patient :p).
|
||
|
||
Issues are welcome, I'm sure that you'll find horrible, terrible, crazy bugs
|
||
faster than me. I'll release a version 0.10.1 if needed.
|
||
|
||
What's next? It's time to fix and improve the storage methods. A real API for
|
||
the storage modules is a good beginning, many pull requests are already ready
|
||
to be discussed and merged, and we will probably get some good news about
|
||
performance this time. Who said "databases, please"?
|
||
|
||
## July 12, 2013 - Radicale 0.8
|
||
|
||
Radicale 0.8 is out!
|
||
|
||
|
||
### 0.8 - Rainbow
|
||
|
||
* New authentication and rights management modules (by Matthias Jordan)
|
||
* Experimental database storage
|
||
* Command-line option for custom configuration file (by Mark Adams)
|
||
* Root URL not at the root of a domain (by Clint Adams, Fabrice Bellet, Vincent Untz)
|
||
* Improved support for iCal, CalDAVSync, CardDAVSync, CalDavZAP and CardDavMATE
|
||
* Empty PROPFIND requests handled (by Christoph Polcin)
|
||
* Colon allowed in passwords
|
||
* Configurable realm message
|
||
|
||
This version brings some of the biggest changes since Radicale's creation,
|
||
including an experimental support of database storage, clean authentication
|
||
modules, and rights management finally designed for real users.
|
||
|
||
So, dear user, be careful: **this version changes important things in the
|
||
configuration file, so check twice that everything is OK when you update to
|
||
0.8, or you can have big problems**.
|
||
|
||
More and more clients are supported, as a lot of bug fixes and features have
|
||
been added for this purpose. And before you ask: yes, 2 web-based clients,
|
||
[CalDavZAP and CardDavMATE](http://www.inf-it.com/open-source/clients/), are
|
||
now supported!
|
||
|
||
Even if there has been a lot of time to test these new features, I am pretty
|
||
sure that some really annoying bugs have been left in this version. We will
|
||
probably release minor versions with bugfixes during the next weeks, and it
|
||
will not take one more year to reach 0.8.1.
|
||
|
||
The documentation has been updated, but some parts are missing and some may be
|
||
out of date. You can [report bugs](https://github.com/Kozea/Radicale/issues)
|
||
or even [write documentation directly on GitHub](https://github.com/Kozea/Radicale/blob/website/pages/user_documentation.rst)
|
||
if you find something strange (and you probably will).
|
||
|
||
If anything is not clear, or if the way rights work is a bit complicated to
|
||
understand, or if you are so happy because everything works so well, you can
|
||
[share your thoughts](#contribute)!
|
||
|
||
It has been a real pleasure to work on this version, with brilliant ideas and
|
||
interesting bug reports from the community. I'd really like to thank all the
|
||
people reporting bugs, chatting on IRC, sending mails and proposing pull
|
||
requests: you are awesome.
|
||
|
||
## August 3, 2012 - Radicale 0.7.1
|
||
|
||
Radicale 0.7.1 is out!
|
||
|
||
|
||
### 0.7.1 - Waterfalls
|
||
|
||
* Many address books fixes
|
||
* New IMAP ACL (by Daniel Aleksandersen)
|
||
* PAM ACL fixed (by Daniel Aleksandersen)
|
||
* Courier ACL fixed (by Benjamin Frank)
|
||
* Always set display name to collections (by Oskari Timperi)
|
||
* Various DELETE responses fixed
|
||
|
||
It's been a long time since the last version… As usual, many people have
|
||
contributed to this new version, that's a pleasure to get these pull requests.
|
||
|
||
Most of the commits are bugfixes, especially about ACL backends and address
|
||
books. Many clients (including aCal and SyncEvolution) will be much happier
|
||
with this new version than with the previous one.
|
||
|
||
By the way, one main new feature has been added: a new IMAP ACL backend, by
|
||
Daniel. And about authentication, exciting features are coming soon, stay
|
||
tuned!
|
||
|
||
Next time, as many mails have come from angry and desperate coders, tests will
|
||
be *finally* added to help them to add features and fix bugs. And after that,
|
||
who knows, it may be time to release Radicale 1.0…
|
||
|
||
## March 22, 2012 - Radicale 0.7
|
||
|
||
Radicale 0.7 is out, at least!
|
||
|
||
|
||
### 0.7 - Eternal Sunshine
|
||
|
||
* Repeating events
|
||
* Collection deletion
|
||
* Courier and PAM authentication methods
|
||
* CardDAV support
|
||
* Custom LDAP filters supported
|
||
|
||
**A lot** of people have reported bugs, proposed new features, added useful
|
||
code and tested many clients. Thank you Lynn, Ron, Bill, Patrick, Hidde,
|
||
Gerhard, Martin, Brendan, Vladimir, and everybody I've forgotten.
|
||
|
||
## January 5, 2012 - Radicale 0.6.4, News from Calypso
|
||
|
||
New year, new release. Radicale 0.6.4 has a really short changelog:
|
||
|
||
|
||
### 0.6.4 - Tulips
|
||
|
||
* Fix the installation with Python 3.1
|
||
|
||
The bug was in fact caused by a
|
||
[bug in Python 3.1](http://bugs.python.org/issue9561), everything should be OK
|
||
now.
|
||
|
||
|
||
### Calypso
|
||
|
||
After a lot of changes in Radicale, Keith Packard has decided to launch a fork
|
||
called [Calypso](http://keithp.com/blogs/calypso/), with nice features such
|
||
as a Git storage mechanism and a CardDAV support.
|
||
|
||
There are lots of differences between the two projects, but the final goal for
|
||
Radicale is to provide these new features as soon as possible. Thanks to the
|
||
work of Keith and other people on GitHub, a basic CardDAV support has been
|
||
added in the [carddav branch](https://github.com/Kozea/Radicale/tree/carddav)
|
||
and already works with Evolution. Korganizer also works with existing address
|
||
books, and CardDAV-Sync will be tested soon. If you want to test other clients,
|
||
please let us know!
|
||
|
||
## November 3, 2011 - Radicale 0.6.3
|
||
|
||
Radicale version 0.6.3 has been released, with bugfixes that could be
|
||
interesting for you!
|
||
|
||
|
||
### 0.6.3 - Red Roses
|
||
|
||
* MOVE requests fixed
|
||
* Faster REPORT answers
|
||
* Executable script moved into the package
|
||
|
||
|
||
### What's New Since 0.6.2?
|
||
|
||
The MOVE requests were suffering a little bug that is fixed now. These requests
|
||
are only sent by Apple clients, Mac users will be happy.
|
||
|
||
The REPORT request were really, really slow (several minutes for large
|
||
calendars). This was caused by an awful algorithm parsing the entire calendar
|
||
for each event in the calendar. The calendar is now only parsed three times,
|
||
and the events are found in a Python list, turning minutes into seconds! Much
|
||
better, but far from perfection…
|
||
|
||
Finally, the executable script parsing the command line options and starting
|
||
the HTTP servers has been moved from the ``radicale.py`` file into the
|
||
``radicale`` package. Two executable are now present in the archive: the good
|
||
old ``radicale.py``, and ``bin/radicale``. The second one is only used by
|
||
``setup.py``, where the hack used to rename ``radicale.py`` into ``radicale``
|
||
has therefore been removed. As a consequence, you can now launch Radicale with
|
||
the simple ``python -m radicale`` command, without relying on an executable.
|
||
|
||
|
||
### Time for a Stable Release!
|
||
|
||
The next release may be a stable release, symbolically called 1.0. Guess what's
|
||
missing? Tests, of course!
|
||
|
||
A non-regression testing suite, based on the clients' requests, will soon be
|
||
added to Radicale. We're now thinking about a smart solution to store the
|
||
tests, to represent the expected answers and to launch the requests. We've got
|
||
crazy ideas, so be prepared: you'll definitely *want* to write tests during the
|
||
next weeks!
|
||
|
||
Repeating events, PAM and Courier authentication methods have already been
|
||
added in master. You'll find them in the 1.0 release!
|
||
|
||
|
||
### What's Next?
|
||
|
||
Being stable is one thing, being cool is another one. If you want some cool new
|
||
features, you may be interested in:
|
||
|
||
- WebDAV and CardDAV support
|
||
- Filters and rights management
|
||
- Multiple storage backends, such as databases and git
|
||
- Freebusy periods
|
||
- Email alarms
|
||
|
||
Issues have been reported in the bug tracker, you can follow there the latest
|
||
news about these features. Your beloved text editor is waiting for you!
|
||
|
||
## September 27, 2011 - Radicale 0.6.2
|
||
|
||
0.6.2 is out with minor bugfixes.
|
||
|
||
### 0.6.2 - Seeds
|
||
|
||
* iPhone and iPad support fixed
|
||
* Backslashes replaced by slashes in PROPFIND answers on Windows
|
||
* PyPI archive set as default download URL
|
||
|
||
## August 28, 2011 - Radicale 0.6.1, Changes, Future
|
||
|
||
As previously imagined, a new 0.6.1 version has been released, mainly fixing
|
||
obvious bugs.
|
||
|
||
|
||
### 0.6.1 - Growing Up
|
||
|
||
* Example files included in the tarball
|
||
* htpasswd support fixed
|
||
* Redirection loop bug fixed
|
||
* Testing message on GET requests
|
||
|
||
The changelog is really small, so there should be no real new problems since
|
||
0.6. The example files for logging, FastCGI and WSGI are now included in the
|
||
tarball, for the pleasure of our dear packagers!
|
||
|
||
A new branch has been created for various future bug fixes. You can expect to
|
||
get more 0.6.x versions, making this branch a kind of "stable" branch with no
|
||
big changes.
|
||
|
||
|
||
### GitHub, Mailing List, New Website
|
||
|
||
A lot of small changes occurred during the last weeks.
|
||
|
||
If you're interested in code and new features, please note that we moved the
|
||
project from Gitorious to GitHub. Being hosted by Gitorious was a
|
||
nice experience, but the service was not that good and we were missing some
|
||
useful features such as git hooks. Moreover, GitHub is really popular, we're
|
||
sure that we'll meet a lot of kind users and coders there.
|
||
|
||
We've also created a mailing-list on Librelist to keep a public
|
||
trace of the mails we're receiving. It a bit empty now, but we're sure that
|
||
you'll soon write us some kind words. For example, you can tell us what you
|
||
think of our new website!
|
||
|
||
|
||
### Future Features
|
||
|
||
In the next weeks, new exciting features are coming in the master branch! Some
|
||
of them are almost ready:
|
||
|
||
- Henry-Nicolas has added the support for the PAM and Courier-Authdaemon
|
||
authentication mechanisms.
|
||
- An anonymous called Keith Packard has prepared some small changes, such as
|
||
one file per event, cache and git versioning. Yes. Really.
|
||
|
||
As you can find in the [Radicale Roadmap](http://redmine.kozea.fr/versions/),
|
||
tests, rights and filters are expected for 0.7.
|
||
|
||
## August 1, 2011 - Radicale 0.6 Released
|
||
|
||
Time for a new release with **a lot** of new exciting features!
|
||
|
||
### 0.6 - Sapling
|
||
|
||
* WSGI support
|
||
* IPv6 support
|
||
* Smart, verbose and configurable logs
|
||
* Apple iCal 4 and iPhone support (by Łukasz Langa)
|
||
* CalDAV-Sync support (by Marten Gajda)
|
||
* aCal support
|
||
* KDE KOrganizer support
|
||
* LDAP auth backend (by Corentin Le Bail)
|
||
* Public and private calendars (by René Neumann)
|
||
* PID file
|
||
* MOVE requests management
|
||
* Journal entries support
|
||
* Drop Python 2.5 support
|
||
|
||
Well, it's been a little longer than expected, but for good reasons: a lot of
|
||
features have been added, and a lot of clients are known to work with Radicale,
|
||
thanks to kind contributors. That's definitely good news! But…
|
||
|
||
Testing all the clients is really painful, moreover for the ones from Apple (I
|
||
have no Mac nor iPhone of my own). We should seriously think of automated
|
||
tests, even if it's really hard to maintain, and maybe not that useful. If
|
||
you're interested in tests, you can look at
|
||
[the wonderful regression suite of DAViCal](http://repo.or.cz/w/davical.git/tree/HEAD:/testing/tests/regression-suite).
|
||
|
||
The new features, for example the WSGI support, are also poorly documented. If
|
||
you have some Apache or lighttpd configuration working with Radicale, you can
|
||
make the world a little bit better by writing a paragraph or two in the
|
||
[Radicale documentation](https://gitorious.org/radicale/website). It's simple
|
||
plain text, don't be afraid!
|
||
|
||
Because of all these changes, Radicale 0.6 may be a little bit buggy; a 0.6.1
|
||
will probably be released soon, fixing small problems with clients and
|
||
features. Get ready to report bugs, I'm sure that you can find one (and fix
|
||
it)!
|
||
|
||
## July 2, 2011 - Feature Freeze for 0.6
|
||
|
||
According to the [roadmap](http://redmine.kozea.fr/projects/radicale/roadmap),
|
||
a lot of features have been added since Radicale 0.5, much more than
|
||
expected. It's now time to test Radicale with your favourite client and to
|
||
report bugs before we release the next stable version!
|
||
|
||
Last week, the iCal and iPhone support written by Łukasz has been fixed in
|
||
order to restore the broken Lightning support. After two afternoons of tests
|
||
with Rémi, we managed to access the same calendar with Lightning, iCal, iPhone
|
||
and Evolution, and finally discovered that CalDAV could also be a perfect
|
||
instant messaging protocol between a Mac, a PC and a phone.
|
||
|
||
After that, we've had the nice surprise to see events displayed without a
|
||
problem (but after some strange steps of configuration) by aCal on Salem's
|
||
Android phone.
|
||
|
||
It was Friday, fun fun fun fun.
|
||
|
||
So, that's it: Radicale supports Lightning, Evolution, Kontact, aCal for
|
||
Android, iPhone and iCal. Of course, before releasing a new tarball:
|
||
|
||
- [documentation](1.1.html#documentation/user-documentation/simple-usage/starting-the-client) is needed for the
|
||
new clients that are not documented yet (Kontact, aCal and iPhone);
|
||
- tests are welcome, particularly for the Apple clients that I can't test
|
||
anymore;
|
||
- no more features will be added, they'll wait in separate branches for the 0.7
|
||
development.
|
||
|
||
Please [report bugs](http://redmine.kozea.fr/projects/radicale/issues) if
|
||
anything goes wrong during your tests, or just let us know
|
||
[by Jabber or by mail](#contribute) if everything is OK.
|
||
|
||
## May 1, 2011 - Ready for WSGI
|
||
|
||
Here it is! Radicale is now ready to be launched behind your favourite HTTP
|
||
server (Apache, Lighttpd, Nginx or Tomcat for example). That's really good
|
||
news, because:
|
||
|
||
- Real HTTP servers are much more efficient and reliable than the default
|
||
Python server used in Radicale;
|
||
- All the authentication backends available for your server will be available
|
||
for Radicale;
|
||
- Thanks to [flup](http://trac.saddi.com/flup), Radicale can be interfaced
|
||
with all the servers supporting CGI, AJP, FastCGI or SCGI;
|
||
- Radicale works very well without any additional server, without any
|
||
dependencies, without configuration, just as it was working before;
|
||
- This one more feature removes useless code, less is definitely more.
|
||
|
||
The WSGI support has only be tested as a stand-alone executable and behind
|
||
Lighttpd, you should definitely try if it works with you favourite server too!
|
||
|
||
No more features will be added before (quite) a long time, because a lot of
|
||
documentation and test is waiting for us. If you want to write tutorials for
|
||
some CalDAV clients support (iCal, Android, iPhone), HTTP servers support or
|
||
logging management, feel free to fork the documentation git repository and ask
|
||
for a merge. It's plain text, I'm sure you can do it!
|
||
|
||
## April 30, 2011 - Apple iCal Support
|
||
|
||
After a long, long work, the iCal support has finally been added to Radicale!
|
||
Well, this support is only for iCal 4 and is highly experimental, but you can
|
||
test it right now with the git master branch. Bug reports are welcome!
|
||
|
||
Dear MacOS users, you can thank all the gentlemen who sended a lot of debugging
|
||
iformation. Special thanks to Andrew from DAViCal, who helped us a lot with his
|
||
tips and his tests, and Rémi Hainaud who lent his laptop for the final tests.
|
||
|
||
The default server address is ``localhost:5232/user/``, where calendars can be
|
||
added. Multiple calendars and owner-less calendars are not tested yet, but they
|
||
should work quite well. More documentation will be added during the next
|
||
days. It will then be time to release the Radicale 0.6 version, and work on the
|
||
WSGI support.
|
||
|
||
## April 25, 2011 - Two Features and One New Roadmap
|
||
|
||
Two features have just reached the master branch, and the roadmap has been
|
||
refreshed.
|
||
|
||
### LDAP Authentication
|
||
|
||
Thanks to Corentin, the LDAP authentication is now included in Radicale. The
|
||
support is experimental and may suffer unstable connexions and security
|
||
problems. If you are interested in this feature (a lot of people seem to be),
|
||
you can try it and give some feedback.
|
||
|
||
No SSL support is included yet, but this may be quite easy to add. By the way,
|
||
serious authentication methods will rely on a "real" HTTP server, as soon as
|
||
Radicale supports WSGI.
|
||
|
||
### Journal Entries
|
||
|
||
Mehmet asked for the journal entries (aka. notes or memos) support, that's
|
||
done! This also was an occasion to clean some code in the iCal parser, and to
|
||
add a much better management of multi-lines entries. People experiencing crazy
|
||
`X-RADICALE-NAME` entries can now clean their files, Radicale won't pollute
|
||
them again.
|
||
|
||
### New Roadmap
|
||
|
||
Except from htpasswd and LDAP, most of the authentication backends (database,
|
||
SASL, PAM, user groups) are not really easy to include in Radicale. The easiest
|
||
solution to solve this problem is to give Radicale a CGI support, to put it
|
||
behind a solid server such as Apache. Of course, CGI is not enough: a WSGI
|
||
support is quite better, with the FastCGI, AJP and SCGI backends offered by
|
||
[flup](http://trac.saddi.com/flup/). Quite exciting, isn't it?
|
||
|
||
That's why it was important to add new versions on the roadmap. The 0.6 version
|
||
is now waiting for the Apple iCal support, and of course for some tests to kill
|
||
the last remaining bugs. The only 0.7 feature will be WSGI, allowing many new
|
||
authentication methods and a real multithread support.
|
||
|
||
After that, 0.8 may add CalDAV rights and filters, while 1.0 will draw
|
||
thousands of rainbows and pink unicorns (WebDAV sync, CardDAV, Freebusy). A lot
|
||
of funky work is waiting for you, hackers!
|
||
|
||
### Bugs
|
||
|
||
Many bugs have also been fixed, most of them due to the owner-less calendars
|
||
support. Radicale 0.6 may be out in a few weeks, you should spend some time
|
||
testing the master branch and filling the bug tracker.
|
||
|
||
## April 10, 2011 - New Features
|
||
|
||
Radicale 0.5 was released only 8 days ago, but 3 new features have already been
|
||
added to the master branch:
|
||
|
||
- IPv6 support, with multiple addresses/ports support
|
||
- Logs and debug mode
|
||
- Owner-less calendars
|
||
|
||
Most of the code has been written by Necoro and Corentin, and that was not easy
|
||
at all: Radicale is now multithreaded! For sure, you can find many bugs and
|
||
report them on the
|
||
[bug tracker](http://redmine.kozea.fr/projects/radicale/issues). And if you're
|
||
fond of logging, you can even add a default configuration file and more debug
|
||
messages in the source.
|
||
|
||
## April 2, 2011 - Radicale 0.5 Released
|
||
|
||
Radicale 0.5 is out! Here is what's new:
|
||
|
||
### 0.5 - Historical Artifacts
|
||
|
||
* Calendar depth
|
||
* iPhone support
|
||
* MacOS and Windows support
|
||
* HEAD requests management
|
||
* htpasswd user from calendar path
|
||
|
||
iPhone support, but no iCal support for 0.5, despite our hard work, sorry!
|
||
After 1 month with no more activity on the dedicated bug, it was time to forget
|
||
it and hack on new awesome features. Thanks for your help, dear Apple users, I
|
||
keep the hope that one day, Radicale will work with you!
|
||
|
||
So, what's next? As promised, some cool git branches will soon be merged, with
|
||
LDAP support, logging, IPv6 and anonymous calendars. Sounds pretty cool, heh?
|
||
Talking about new features, more and more people are asking for a CardDAV
|
||
support in Radicale. A git branch and a feature request are open, feel free to
|
||
hack and discuss.
|
||
|
||
## February 3, 2011 - Jabber Room and iPhone Support
|
||
|
||
After a lot of help and testing work from Andrew, Björn, Anders, Dorian and
|
||
Pete (and other ones we could have forgotten), a simple iPhone support has been
|
||
added in the git repository. If you are interested, you can test this feature
|
||
*right now* by
|
||
[downloading the latest git version](#download//git-repository)
|
||
(a tarball is even available too if you don't want or know how to use git).
|
||
|
||
No documentation has been written yet, but using the right URL in the
|
||
configuration should be enough to synchronize your calendars. If you have any
|
||
problems, you can ask by joining our new Jabber room:
|
||
radicale@room.jabber.kozea.fr.
|
||
|
||
Radicale 0.5 will be released as soon as the iCal support is ready. If you have
|
||
an Apple computer, Python skills and some time to spend, we'd be glad to help
|
||
you debugging Radicale.
|
||
|
||
## October 21, 2010 - News from Radicale
|
||
|
||
During the last weeks, Radicale has not been idle, even if no news have been
|
||
posted since August. Thanks to Pete, Pierre-Philipp and Andrew, we're trying to
|
||
add a better support on MacOS, Windows and mobile devices like iPhone and
|
||
Android-based phones.
|
||
|
||
All the tests on Windows have been successful: launching Radicale and using
|
||
Lightning as client works without any problems. On Android too, some testers
|
||
have reported clients working with Radicale. These were the good news.
|
||
|
||
The bad news come from Apple: both iPhone and MacOS default clients are not
|
||
working yet, despite the latest enhancements given to the PROPFIND
|
||
requests. The problems are quite hard to debug due to our lack of Apple
|
||
hardware, but Pete is helping us in this difficult quest! Radicale 0.5 will be
|
||
out as soon as these two clients are working.
|
||
|
||
Some cool stuff is coming next, with calendar collections and groups, and a
|
||
simple web-based CalDAV client in early development. Stay tuned!
|
||
|
||
## August 8, 2010 - Radicale 0.4 Released
|
||
|
||
Radicale 0.4 is out! Here is what's new:
|
||
|
||
### 0.4 - Hot Days Back
|
||
|
||
* Personal calendars
|
||
* HEAD requests
|
||
* Last-Modified HTTP header
|
||
* ``no-ssl`` and ``foreground`` options
|
||
* Default configuration file
|
||
|
||
This release has mainly been released to help our dear packagers to include a default configuration file and to write init scripts. Big thanks to Necoro for his work on the new Gentoo ebuild!
|
||
|
||
## July 4, 2010 - Three Features Added Last Week
|
||
|
||
Some features have been added in the git repository during the last weeks,
|
||
thanks to Jerome and Mariusz!
|
||
|
||
Personal Calendars
|
||
Calendars accessed through the htpasswd ACL module can now be
|
||
personal. Thanks to the ``personal`` option, a user called ``bob`` can access
|
||
calendars at ``/bob/*`` but not to the ``/alice/*`` ones.
|
||
|
||
HEAD Requests
|
||
Radicale can now answer HEAD requests. HTTP headers can be retrieved thanks
|
||
to this request, without getting contents given by the GET requests.
|
||
|
||
Last-Modified HTTP header
|
||
The Last-Modified header gives the last time when the calendar has been
|
||
modified. This is used by some clients to cache the calendars and not
|
||
retrieving them if they have not been modified.
|
||
|
||
## June 14, 2010 - Radicale 0.3 Released
|
||
|
||
Radicale 0.3 is out! Here is what’s new:
|
||
|
||
### 0.3 - Dancing Flowers
|
||
|
||
* Evolution support
|
||
* Version management
|
||
|
||
The website changed a little bit too, with some small HTML5 and CSS3 features
|
||
such as articles, sections, transitions, opacity, box shadows and rounded
|
||
corners. If you’re reading this website with Internet Explorer, you should
|
||
consider using a standard-compliant browser!
|
||
|
||
Radicale is now included in Squeeze, the testing branch of Debian. A
|
||
[Radicale ebuild for Gentoo](http://bugs.gentoo.org/show_bug.cgi?id=322811) has
|
||
been proposed too. If you want to package Radicale for another distribution,
|
||
you’re welcome!
|
||
|
||
Next step is 0.5, with calendar collections, and Windows and MacOS support.
|
||
|
||
## May 31, 2010 - May News
|
||
|
||
### News from contributors
|
||
|
||
Jonas Smedegaard packaged Radicale for Debian last week. Two packages, called
|
||
``radicale`` for the daemon and ``python-radicale`` for the module, have been
|
||
added to Sid, the unstable branch of Debian. Thank you, Jonas!
|
||
|
||
Sven Guckes corrected some of the strange-English-sentences present on this
|
||
website. Thank you, Sven!
|
||
|
||
### News from software
|
||
|
||
A simple ``VERSION`` has been added in the library: you can now play with
|
||
``radicale.VERSION`` and ``$radicale --version``.
|
||
|
||
After playing with the version (should not be too long), you may notice that
|
||
the next version is called 0.3, and not 0.5 as previously decided. The 0.3 main
|
||
goal is to offer the support for Evolution as soon as possible, without waiting
|
||
for the 0.5. After more than a month of test, we corrected all the bugs we
|
||
found and everything seems to be fine; we can imagine that a brand new tarball
|
||
will be released during the first days of June.
|
||
|
||
## April 19, 2010 - Evolution Supported
|
||
|
||
Radicale now supports another CalDAV client:
|
||
[Evolution, the default mail, addressbook and calendaring client for Gnome](http://projects.gnome.org/evolution/).
|
||
This feature was quite easy to add, as it required less than 20 new lines of
|
||
code in the requests handler.
|
||
|
||
If you are interested, just clone the
|
||
[git repository](http://www.gitorious.org/radicale/radicale).
|
||
|
||
## April 13, 2010 - Radicale 0.2 Released
|
||
|
||
Radicale 0.2 is out! Here is what’s new:
|
||
|
||
### 0.2 - Snowflakes
|
||
|
||
* Sunbird pre-1.0 support
|
||
* SSL connection
|
||
* Htpasswd authentication
|
||
* Daemon mode
|
||
* User configuration
|
||
* Twisted dependency removed
|
||
* Python 3 support
|
||
* Real URLs for PUT and DELETE
|
||
* Concurrent modification reported to users
|
||
* Many bugs fixed by Roger Wenham
|
||
|
||
First of all, we would like to thank Roger Wenham for his bugfixes and his
|
||
supercool words.
|
||
|
||
You may have noticed that Sunbird 1.0 has not been released, but according to
|
||
the Mozilla developers, 1.0pre is something like a final version.
|
||
|
||
You may have noticed too that Radicale can be
|
||
[downloaded from PyPI](http://pypi.python.org/pypi/Radicale/0.2). Of course, it
|
||
is also available on the [download page](#download).
|
||
|
||
## January 21, 2010 - HTTPS and Authentication
|
||
|
||
HTTPS connections and authentication have been added to Radicale this
|
||
week. Command-line options and personal configuration files are also ready for
|
||
test. According to the TODO file included in the package, the next version will
|
||
finally be 0.2, when sunbird 1.0 is out. Go, Mozilla hackers, go!
|
||
|
||
HTTPS connection
|
||
HTTPS connections are now available using the standard TLS mechanisms. Give
|
||
Radicale a private key and a certificate, and your data are now safe.
|
||
|
||
Authentication
|
||
A simple authentication architecture is now available, allowing different
|
||
methods thanks to different modules. The first two modules are ``fake`` (no
|
||
authentication) and ``htpasswd`` (authentication with an ``htpasswd`` file
|
||
created by the Apache tool). More methods such as LDAP are coming soon!
|
||
|
||
## January 15, 2010 - Ready for Python 3
|
||
|
||
Dropping Twisted dependency was the first step leading to another big feature:
|
||
Radicale now works with Python 3! The code was given a small cleanup, with some
|
||
simplifications mainly about encoding. Before the 0.1.1 release, feel free to
|
||
test the git repository, all Python versions from 2.5 should be OK.
|
||
|
||
## January 11, 2010 - Twisted no Longer Required
|
||
|
||
Good news! Radicale 0.1.1 will support Sunbird 1.0, but it has another great
|
||
feature: it has no external dependency! Twisted is no longer required for the
|
||
git version, removing about 50 lines of code.
|
||
|
||
## December 31, 2009 - Lightning and Sunbird 1.0b2pre Support
|
||
|
||
Lightning/Sunbird 1.0b2pre is out, adding minor changes in CalDAV support. A
|
||
[new commit](http://www.gitorious.org/radicale/radicale/commit/330283e) makes
|
||
Radicale work with versions 0.9, 1.0b1 et 1.0b2. Moreover, etags are now quoted
|
||
according to the RFC 2616.
|
||
|
||
## December 9, 2009 - Thunderbird 3 released
|
||
|
||
[Thunderbird 3 is out](http://www.mozillamessaging.com/thunderbird/3.0/releasenotes/),
|
||
and Lightning/Sunbird 1.0 should be released in a few days. The
|
||
[last commit in git](http://gitorious.org/radicale/radicale/commit/6545bc8)
|
||
should make Radicale work with versions 0.9 and 1.0b1pre. Radicale 0.1.1 will
|
||
soon be released adding support for version 1.0.
|
||
|
||
## September 1, 2009 - Radicale 0.1 Released
|
||
|
||
First Radicale release! Here is the changelog:
|
||
|
||
### 0.1 - Crazy Vegetables
