Laconica 0.6.0
-12 September 2008
+22 September 2008
This is the README file for Laconica, the Open Source microblogging
platform. It includes installation instructions, descriptions of
of using the software, and if you do not wish to share your
modifications, *YOU MAY NOT INSTALL LACONICA*.
+Additional library software has been made available in the 'extlib'
+directory. All of it is Free Software and can be distributed under
+liberal terms, but those terms may differ in detail from the AGPL's
+particulars. See each package's license file in the extlib directory
+for additional terms.
+
+New this version
+================
+
+New features in version 0.6.0 include:
+
+* Invitations by email.
+* Users can mark messages as "favorites" (only Web, not API).
+* A bridge to push messages on the Laconica instance to an account on
+ Twitter.
+* Direct private messages between users on a server (only Web, not API
+ or IM or SMS).
+* Restructured off-line daemons.
+
Prerequisites
=============
- Curl. This is for fetching files by HTTP.
- XMLWriter. This is for formatting XML and HTML output.
- MySQL. For accessing the database.
+- GD. For scaling down avatar images.
For some functionality, you will also need the following extensions:
Themes
------
+There are two themes shipped with this version of Laconica: "stoica",
+which is what the Identi.ca site uses, and "default", which is a good
+basis for other sites.
+
+As of right now, your ability to change the theme is site-wide; users
+can't choose their own theme. Additionally, the only thing you can
+change in the theme is CSS stylesheets and some image files; you can't
+change the HTML output, like adding or removing menu items.
+
+You can choose a theme using the $config['site']['theme'] element in
+the config.php file. See below for details.
+
+You can add your own theme by making a sub-directory of the 'theme'
+subdirectory with the name of your theme. Each theme can have the
+following files:
+
+display.css: a CSS2 file for "default" styling for all browsers.
+ie6.css: a CSS2 file for override styling for fixing up Internet
+ Explorer 6.
+ie7.css: a CSS2 file for override styling for fixing up Internet
+ Explorer 7.
+logo.png: a logo image for the site.
+default-avatar-profile.png: a 96x96 pixel image to use as the avatar for
+ users who don't upload their own.
+default-avatar-stream.png: Ditto, but 48x48. For streams of notices.
+default-avatar-mini.png: Ditto ditto, but 24x24. For subscriptions
+ listing on profile pages.
+
+You may want to start by copying the files from the default theme to
+your own directory.
+
Translation
-----------
+Translations in Laconica use the gettext system (http://www.gnu.org/software/gettext/).
+Theoretically, you can add your own sub-directory to the locale/
+subdirectory to add a new language to your system. You'll need to
+compile the ".po" files into ".mo" files, however.
+
Upgrading
=========
+If you've been using Laconica 0.5 or lower, or if you've been tracking
+the "darcs" version of the software, you will probably want to upgrade
+and keep your existing data. There is no automated upgrade procedure
+in Laconica 0.6. Try these step-by-step instructions; read to the end
+first before trying them.
+
+0. Download Laconica and set up all the prerequisites as if you were
+ doing a new install.
+1. Make backups of both your database and your Web directory. UNDER NO
+ CIRCUMSTANCES should you try to do an upgrade without a known-good
+ backup. You have been warned.
+2. Shut down Web access to your site, either by turning off your Web
+ server or by redirecting all pages to a "sorry, under maintenance"
+ page.
+3. Shut down XMPP access to your site, typically by shutting down the
+ xmppdaemon.php process and all other daemons that you're running.
+ If you've got "monit" or "cron" automatically restarting your
+ daemons, make sure to turn that off, too.
+4. Shut down SMS and email access to your site. The easy way to do
+ this is to comment out the line piping incoming email to your
+ maildaemon.php file, and running something like "newaliases".
+5. Once all writing processes to your site are turned off, make a
+ final backup of the Web directory and database.
+6. Move your Laconica directory to a backup spot, like "mublog.bak".
+7. Unpack your Laconica 0.6 tarball and move it to "mublog" or
+ wherever your code used to be.
+8. Copy the config.php file and avatar directory from your old
+ directory to your new directory.
+9. Copy htaccess.sample to .htaccess in the new directory. Change the
+ RewriteBase to use the correct path.
+10. Rebuild the database. Go to your Laconica directory and run the
+ rebuilddb.sh script like this:
+
+ ./scripts/rebuilddb.sh rootuser rootpassword database db/laconica.sql
+
+ Here, rootuser and rootpassword are the username and password for a
+ user who can drop and create databases as well as tables; typically
+ that's _not_ the user Laconica runs as.
+11. Use mysql client to log into your database and make sure that the
+ notice, user, profile, subscription etc. tables are non-empty.
+12. Turn back on the Web server, and check that things still work.
+13. Turn back on XMPP bots and email maildaemon. Note that the XMPP
+ bots have changed since version 0.5; see above for details.
+
+If you're upgrading from very old versions, you may want to look at
+the fixup_* scripts in the scripts directories. These will store some
+precooked data in the DB.
+
Configuration options

- );
-Web
----
+enabled: Whether to uses queues. Defaults to false.
+
+license
+-------
+
+The default license to use for your users notices. The default is the
+Creative Commons Attribution 3.0 license, which is probably the right
+choice for any public site. Note that some other servers will not
+accept notices if you apply a stricter license than this.
-Mail
+url: URL of the license, used for links.
+title: Title for the license, like 'Creative Commons Attribution 3.0'.
+image: A button shown on each page for the license.
+
+mail
----
-SMS
----
+This is for configuring out-going email. We use PEAR's Mail module,
+see: http://pear.php.net/manual/en/package.mail.mail.factory.php
-XMPP
+backend: the backend to use for mail, one of 'mail', 'sendmail', and
+ 'smtp'. Defaults to PEAR's default, 'mail'.
+params: if the mail backend requires any parameters, you can provide
+ them in an associative array.
+
+nickname
+--------
+
+This is for configuring nicknames in the service.
+
+blacklist: an array of strings for usernames that may not be
+ registered. A default array exists for strings that are
+ used by Laconica (e.g. 'doc', 'main', 'avatar', 'theme')
+ but you may want to add others if you have other software
+ installed in a subdirectory of Laconica or if you just
+ don't want certain words used as usernames.
+
+avatar
+------
+
+For configuring avatar access.
+
+server: If set, defines another server where avatars are stored in the
+ root directory. Note that the 'avatar' subdir still has to be
+ writeable. You'd typically use this to split HTTP requests on
+ the client to speed up page loading, either with another
+ virtual server or with an NFS or SAMBA share. Clients
+ typically only make 2 connections to a single server at a
+ time (http://ur1.ca/6ih), so this can parallelize the job.
+ Defaults to null.
+
+public
+------
+
+For configuring the public stream.
+
+localonly: If set to true, only messages posted by users of this
+ service (rather than other services, filtered through OMB)
+ are shown in the public stream. Default true.
+
+theme
+-----
+
+server: Like avatars, you can speed up page loading by pointing the
+ theme file lookup to another server (virtual or real). The
+ theme server's root path should map to the Laconica "theme"
+ subdirectory. Defaults to NULL.
+
+xmpp
----
+For configuring the XMPP sub-system.
+
+enabled: Whether to accept and send messages by XMPP. Default false.
+server: server part of XMPP ID for update user.
+port: connection port for clients. Default 5222, which you probably
+ shouldn't need to change.
+user: username for the client connection. Users will receive messages
+ from 'user'@'server'.
+resource: a unique identifier for the connection to the server. This
+ is actually used as a prefix for each XMPP component in the system.
+password: password for the user account.
+host: some XMPP domains are served by machines with a different
+ hostname. (For example, @gmail.com GTalk users connect to
+ talk.google.com). Set this to the correct hostname if that's the
+ case with your server.
+encryption: Whether to encrypt the connection between Laconica and the
+ XMPP server. Defaults to true, but you can get
+ considerably better performance turning it off if you're
+ connecting to a server on the same machine or on a
+ protected network.
+debug: if turned on, this will make the XMPP library blurt out all of
+ the incoming and outgoing messages as XML stanzas. Use as a
+ last resort, and never turn it on if you don't have queues
+ enabled, since it will spit out sensitive data to the browser.
+public: an array of JIDs to send _all_ notices to. This is useful for
+ participating in third-party search and archiving services.
+
+tag
+---
+
+Miscellaneous tagging stuff.
+
+dropoff: Decay factor for tag listing, in seconds.
+ Defaults to exponential decay over ten days; you can twiddle
+ with it to try and get better results for your site.
+
+daemon
+------
+
+For daemon processes.
+
+piddir: directory that daemon processes should write their PID file
+ (process ID) to. Defaults to /var/run/, which is where this
+ stuff should usually go on Unix-ish systems.
+user: If set, the daemons will try to change their effective user ID
+ to this user before running. Probably a good idea, especially if
+ you start the daemons as root. Note: user name, like 'daemon',
+ not 1001.
+group: If set, the daemons will try to change their effective group ID
+ to this named group. Again, a name, not a numerical ID.
+
Troubleshooting
===============
-The primary output for
+The primary output for Laconica is syslog, unless you configured a
+separate logfile. This is probably the first place to look if you're
+getting weird behaviour from Laconica.
+
+If you're tracking the unstable version of Laconica in the darcs
+repository (see below), and you get a compilation error ("unexpected
+T_STRING") in the browser, check to see that you don't have any
+conflicts in your code.
