4 The main configuration file for StatusNet (excepting configurations for
5 dependency software) is config.php in your StatusNet directory. If you
6 edit any other file in the directory, like lib/default.php (where most
7 of the defaults are defined), you will lose your configuration options
8 in any upgrade, and you will wish that you had been more careful.
10 Starting with version 0.9.0, a Web based configuration panel has been
11 added to StatusNet. The preferred method for changing config options is
14 A command-line script, setconfig.php, can be used to set individual
15 configuration options. It's in the scripts/ directory.
17 Starting with version 0.7.1, you can put config files in the
18 /etc/statusnet/ directory on your server, if it exists. Config files
19 will be included in this order:
21 * /etc/statusnet/statusnet.php - server-wide config
22 * /etc/statusnet/<servername>.php - for a virtual host
23 * /etc/statusnet/<servername>_<pathname>.php - for a path
24 * INSTALLDIR/config.php - for a particular implementation
26 Almost all configuration options are made through a two-dimensional
27 associative array, cleverly named $config. A typical configuration
30 $config['section']['option'] = value;
32 For brevity, the following documentation describes each section and
38 This section is a catch-all for site-wide variables.
40 name: the name of your site, like 'YourCompany Microblog'.
41 server: the server part of your site's URLs, like 'example.net'.
42 path: The path part of your site's URLs, like 'statusnet' or ''
44 fancy: whether or not your site uses fancy URLs (see Fancy URLs
45 section above). Default is false.
46 logfile: full path to a file for StatusNet to save logging
47 information to. You may want to use this if you don't have
49 logdebug: whether to log additional debug info like backtraces on
50 hard errors. Default false.
51 locale_path: full path to the directory for locale data. Unless you
52 store all your locale data in one place, you probably
53 don't need to use this.
54 language: default language for your site. Defaults to US English.
55 Note that this is overridden if a user is logged in and has
56 selected a different language. It is also overridden if the
57 user is NOT logged in, but their browser requests a different
58 langauge. Since pretty much everybody's browser requests a
59 language, that means that changing this setting has little or
60 no effect in practice.
61 languages: A list of languages supported on your site. Typically you'd
62 only change this if you wanted to disable support for one
64 "unset($config['site']['languages']['de'])" will disable
66 theme: Theme for your site (see Theme section). Two themes are
67 provided by default: 'default' and 'stoica' (the one used by
68 Identi.ca). It's appreciated if you don't use the 'stoica' theme
69 except as the basis for your own.
70 email: contact email address for your site. By default, it's extracted
71 from your Web server environment; you may want to customize it.
72 broughtbyurl: name of an organization or individual who provides the
73 service. Each page will include a link to this name in the
74 footer. A good way to link to the blog, forum, wiki,
75 corporate portal, or whoever is making the service available.
76 broughtby: text used for the "brought by" link.
77 timezone: default timezone for message display. Users can set their
78 own time zone. Defaults to 'UTC', which is a pretty good default.
79 closed: If set to 'true', will disallow registration on your site.
80 This is a cheap way to restrict accounts to only one
81 individual or group; just register the accounts you want on
82 the service, *then* set this variable to 'true'.
83 inviteonly: If set to 'true', will only allow registration if the user
84 was invited by an existing user.
85 private: If set to 'true', anonymous users will be redirected to the
86 'login' page. Also, API methods that normally require no
87 authentication will require it. Note that this does not turn
88 off registration; use 'closed' or 'inviteonly' for the
90 notice: A plain string that will appear on every page. A good place
91 to put introductory information about your service, or info about
92 upgrades and outages, or other community info. Any HTML will
94 logo: URL of an image file to use as the logo for the site. Overrides
95 the logo in the theme, if any.
96 ssllogo: URL of an image file to use as the logo on SSL pages. If unset,
97 theme logo is used instead.
98 ssl: Whether to use SSL and https:// URLs for some or all pages.
99 Possible values are 'always' (use it for all pages), 'never'
100 (don't use it for any pages), or 'sometimes' (use it for
101 sensitive pages that include passwords like login and registration,
102 but not for regular pages). Default to 'never'.
103 sslserver: use an alternate server name for SSL URLs, like
104 'secure.example.org'. You should be careful to set cookie
105 parameters correctly so that both the SSL server and the
106 "normal" server can access the session cookie and
107 preferably other cookies as well.
108 shorturllength: ignored. See 'url' section below.
109 dupelimit: minimum time allowed for one person to say the same thing
110 twice. Default 60s. Anything lower is considered a user
112 textlimit: default max size for texts in the site. Defaults to 0 (no limit).
113 Can be fine-tuned for notices, messages, profile bios and group descriptions.
118 This section is a reference to the configuration options for
119 DB_DataObject (see <http://ur1.ca/7xp>). The ones that you may want to
120 set are listed below for clarity.
122 database: a DSN (Data Source Name) for your StatusNet database. This is
123 in the format 'protocol://username:password@hostname/databasename',
124 where 'protocol' is 'mysql' or 'mysqli' (or possibly 'postgresql', if you
125 really know what you're doing), 'username' is the username,
126 'password' is the password, and etc.
127 ini_yourdbname: if your database is not named 'statusnet', you'll need
128 to set this to point to the location of the
129 statusnet.ini file. Note that the real name of your database
130 should go in there, not literally 'yourdbname'.
131 db_driver: You can try changing this to 'MDB2' to use the other driver
132 type for DB_DataObject, but note that it breaks the OpenID
133 libraries, which only support PEAR::DB.
134 debug: On a database error, you may get a message saying to set this
135 value to 5 to see debug messages in the browser. This breaks
136 just about all pages, and will also expose the username and
138 quote_identifiers: Set this to true if you're using postgresql.
139 type: either 'mysql' or 'postgresql' (used for some bits of
140 database-type-specific SQL in the code). Defaults to mysql.
141 mirror: you can set this to an array of DSNs, like the above
142 'database' value. If it's set, certain read-only actions will
143 use a random value out of this array for the database, rather
144 than the one in 'database' (actually, 'database' is overwritten).
145 You can offload a busy DB server by setting up MySQL replication
146 and adding the slaves to this array. Note that if you want some
147 requests to go to the 'database' (master) server, you'll need
148 to include it in this array, too.
149 utf8: whether to talk to the database in UTF-8 mode. This is the default
150 with new installations, but older sites may want to turn it off
151 until they get their databases fixed up. See "UTF-8 database"
153 schemacheck: when to let plugins check the database schema to add
154 tables or update them. Values can be 'runtime' (default)
155 or 'script'. 'runtime' can be costly (plugins check the
156 schema on every hit, adding potentially several db
157 queries, some quite long), but not everyone knows how to
158 run a script. If you can, set this to 'script' and run
159 scripts/checkschema.php whenever you install or upgrade a
165 By default, StatusNet sites log error messages to the syslog facility.
166 (You can override this using the 'logfile' parameter described above).
168 appname: The name that StatusNet uses to log messages. By default it's
169 "statusnet", but if you have more than one installation on the
170 server, you may want to change the name for each instance so
171 you can track log messages more easily.
172 priority: level to log at. Currently ignored.
173 facility: what syslog facility to used. Defaults to LOG_USER, only
174 reset if you know what syslog is and have a good reason
180 You can configure the software to queue time-consuming tasks, like
181 sending out SMS email or XMPP messages, for off-line processing. See
182 'Queues and daemons' above for how to set this up.
184 enabled: Whether to uses queues. Defaults to false.
185 subsystem: Which kind of queueserver to use. Values include "db" for
186 our hacked-together database queuing (no other server
187 required) and "stomp" for a stomp server.
188 stomp_server: "broker URI" for stomp server. Something like
189 "tcp://hostname:61613". More complicated ones are
190 possible; see your stomp server's documentation for
192 queue_basename: a root name to use for queues (stomp only). Typically
193 something like '/queue/sitename/' makes sense. If running
194 multiple instances on the same server, make sure that
195 either this setting or $config['site']['nickname'] are
196 unique for each site to keep them separate.
198 stomp_username: username for connecting to the stomp server; defaults
200 stomp_password: password for connecting to the stomp server; defaults
203 stomp_persistent: keep items across queue server restart, if enabled.
204 Under ActiveMQ, the server configuration determines if and how
205 persistent storage is actually saved.
207 If using a message queue server other than ActiveMQ, you may
208 need to disable this if it does not support persistence.
210 stomp_transactions: use transactions to aid in error detection.
211 A broken transaction will be seen quickly, allowing a message
212 to be redelivered immediately if a daemon crashes.
214 If using a message queue server other than ActiveMQ, you may
215 need to disable this if it does not support transactions.
217 stomp_acks: send acknowledgements to aid in flow control.
218 An acknowledgement of successful processing tells the server
219 we're ready for more and can help keep things moving smoothly.
221 This should *not* be turned off when running with ActiveMQ, but
222 if using another message queue server that does not support
223 acknowledgements you might need to disable this.
225 softlimit: an absolute or relative "soft memory limit"; daemons will
226 restart themselves gracefully when they find they've hit
227 this amount of memory usage. Defaults to 90% of PHP's global
228 memory_limit setting.
230 inboxes: delivery of messages to receiver's inboxes can be delayed to
231 queue time for best interactive performance on the sender.
232 This may however be annoyingly slow when using the DB queues,
233 so you can set this to false if it's causing trouble.
235 breakout: for stomp, individual queues are by default grouped up for
236 best scalability. If some need to be run by separate daemons,
237 etc they can be manually adjusted here.
239 Default will share all queues for all sites within each group.
240 Specify as <group>/<queue> or <group>/<queue>/<site>,
241 using nickname identifier as site.
243 'main/distrib' separate "distrib" queue covering all sites
244 'xmpp/xmppout/mysite' separate "xmppout" queue covering just 'mysite'
246 max_retries: for stomp, drop messages after N failed attempts to process.
249 dead_letter_dir: for stomp, optional directory to dump data on failed
250 queue processing events after discarding them.
252 stomp_no_transactions: for stomp, the server does not support transactions,
253 so do not try to user them. This is needed for http://www.morbidq.com/.
255 stomp_no_acks: for stomp, the server does not support acknowledgements.
256 so do not try to user them. This is needed for http://www.morbidq.com/.
261 The default license to use for your users notices. The default is the
262 Creative Commons Attribution 3.0 license, which is probably the right
263 choice for any public site. Note that some other servers will not
264 accept notices if you apply a stricter license than this.
266 type: one of 'cc' (for Creative Commons licenses), 'allrightsreserved'
267 (default copyright), or 'private' (for private and confidential
269 owner: for 'allrightsreserved' or 'private', an assigned copyright
270 holder (for example, an employer for a private site). If
271 not specified, will be attributed to 'contributors'.
272 url: URL of the license, used for links.
273 title: Title for the license, like 'Creative Commons Attribution 3.0'.
274 image: A button shown on each page for the license.
279 This is for configuring out-going email. We use PEAR's Mail module,
280 see: http://pear.php.net/manual/en/package.mail.mail.factory.php
282 backend: the backend to use for mail, one of 'mail', 'sendmail', and
283 'smtp'. Defaults to PEAR's default, 'mail'.
284 params: if the mail backend requires any parameters, you can provide
285 them in an associative array.
290 This is for configuring nicknames in the service.
292 blacklist: an array of strings for usernames that may not be
293 registered. A default array exists for strings that are
294 used by StatusNet (e.g. 'doc', 'main', 'avatar', 'theme')
295 but you may want to add others if you have other software
296 installed in a subdirectory of StatusNet or if you just
297 don't want certain words used as usernames.
298 featured: an array of nicknames of 'featured' users of the site.
299 Can be useful to draw attention to well-known users, or
300 interesting people, or whatever.
305 For configuring avatar access.
307 dir: Directory to look for avatar files and to put them into.
308 Defaults to avatar subdirectory of install directory; if
309 you change it, make sure to change path, too.
310 path: Path to avatars. Defaults to path for avatar subdirectory,
311 but you can change it if you wish. Note that this will
312 be included with the avatar server, too.
313 server: If set, defines another server where avatars are stored in the
314 root directory. Note that the 'avatar' subdir still has to be
315 writeable. You'd typically use this to split HTTP requests on
316 the client to speed up page loading, either with another
317 virtual server or with an NFS or SAMBA share. Clients
318 typically only make 2 connections to a single server at a
319 time <http://ur1.ca/6ih>, so this can parallelize the job.
321 ssl: Whether to access avatars using HTTPS. Defaults to null, meaning
322 to guess based on site-wide SSL settings.
327 For configuring the public stream.
329 localonly: If set to true, only messages posted by users of this
330 service (rather than other services, filtered through OStatus)
331 are shown in the public stream. Default true.
332 blacklist: An array of IDs of users to hide from the public stream.
333 Useful if you have someone making excessive Twitterfeed posts
334 to the site, other kinds of automated posts, testing bots, etc.
335 autosource: Sources of notices that are from automatic posters, and thus
336 should be kept off the public timeline. Default empty.
341 server: Like avatars, you can speed up page loading by pointing the
342 theme file lookup to another server (virtual or real).
343 Defaults to NULL, meaning to use the site server.
344 dir: Directory where theme files are stored. Used to determine
345 whether to show parts of a theme file. Defaults to the theme
346 subdirectory of the install directory.
347 path: Path part of theme URLs, before the theme name. Relative to the
348 theme server. It may make sense to change this path when upgrading,
349 (using version numbers as the path) to make sure that all files are
350 reloaded by caching clients or proxies. Defaults to null,
351 which means to use the site path + '/theme'.
352 ssl: Whether to use SSL for theme elements. Default is null, which means
353 guess based on site SSL settings.
354 sslserver: SSL server to use when page is HTTPS-encrypted. If
355 unspecified, site ssl server and so on will be used.
356 sslpath: If sslserver if defined, path to use when page is HTTPS-encrypted.
361 server: You can speed up page loading by pointing the
362 theme file lookup to another server (virtual or real).
363 Defaults to NULL, meaning to use the site server.
364 path: Path part of Javascript URLs. Defaults to null,
365 which means to use the site path + '/js/'.
366 ssl: Whether to use SSL for JavaScript files. Default is null, which means
367 guess based on site SSL settings.
368 sslserver: SSL server to use when page is HTTPS-encrypted. If
369 unspecified, site ssl server and so on will be used.
370 sslpath: If sslserver if defined, path to use when page is HTTPS-encrypted.
371 bustframes: If true, all web pages will break out of framesets. If false,
372 can comfortably live in a frame or iframe... probably. Default
378 For configuring the XMPP sub-system.
380 enabled: Whether to accept and send messages by XMPP. Default false.
381 server: server part of XMPP ID for update user.
382 port: connection port for clients. Default 5222, which you probably
383 shouldn't need to change.
384 user: username for the client connection. Users will receive messages
385 from 'user'@'server'.
386 resource: a unique identifier for the connection to the server. This
387 is actually used as a prefix for each XMPP component in the system.
388 password: password for the user account.
389 host: some XMPP domains are served by machines with a different
390 hostname. (For example, @gmail.com GTalk users connect to
391 talk.google.com). Set this to the correct hostname if that's the
392 case with your server.
393 encryption: Whether to encrypt the connection between StatusNet and the
394 XMPP server. Defaults to true, but you can get
395 considerably better performance turning it off if you're
396 connecting to a server on the same machine or on a
398 debug: if turned on, this will make the XMPP library blurt out all of
399 the incoming and outgoing messages as XML stanzas. Use as a
400 last resort, and never turn it on if you don't have queues
401 enabled, since it will spit out sensitive data to the browser.
402 public: an array of JIDs to send _all_ notices to. This is useful for
403 participating in third-party search and archiving services.
408 For configuring invites.
410 enabled: Whether to allow users to send invites. Default true.
415 Miscellaneous tagging stuff.
417 dropoff: Decay factor for tag listing, in seconds.
418 Defaults to exponential decay over ten days; you can twiddle
419 with it to try and get better results for your site.
424 Settings for the "popular" section of the site.
426 dropoff: Decay factor for popularity listing, in seconds.
427 Defaults to exponential decay over ten days; you can twiddle
428 with it to try and get better results for your site.
433 For daemon processes.
435 piddir: directory that daemon processes should write their PID file
436 (process ID) to. Defaults to /var/run/, which is where this
437 stuff should usually go on Unix-ish systems.
438 user: If set, the daemons will try to change their effective user ID
439 to this user before running. Probably a good idea, especially if
440 you start the daemons as root. Note: user name, like 'daemon',
442 group: If set, the daemons will try to change their effective group ID
443 to this named group. Again, a name, not a numerical ID.
448 You can get a significant boost in performance by caching some
449 database data in memcached <http://www.danga.com/memcached/>.
451 enabled: Set to true to enable. Default false.
452 server: a string with the hostname of the memcached server. Can also
453 be an array of hostnames, if you've got more than one server.
454 base: memcached uses key-value pairs to store data. We build long,
455 funny-looking keys to make sure we don't have any conflicts. The
456 base of the key is usually a simplified version of the site name
457 (like "Identi.ca" => "identica"), but you can overwrite this if
458 you need to. You can safely ignore it if you only have one
459 StatusNet site using your memcached server.
460 port: Port to connect to; defaults to 11211.
467 enabled: Whether to enable post-by-email. Defaults to true. You will
468 also need to set up maildaemon.php.
475 enabled: Whether to enable SMS integration. Defaults to true. Queues
476 should also be enabled.
481 A catch-all for integration with other systems.
483 taguri: base for tag:// URIs. Defaults to site-server + ',2009'.
490 enabled: No longer used. If you set this to something other than true,
491 StatusNet will no longer run.
496 For notice-posting throttles.
498 enabled: Whether to throttle posting. Defaults to false.
499 count: Each user can make this many posts in 'timespan' seconds. So, if count
500 is 100 and timespan is 3600, then there can be only 100 posts
501 from a user every hour.
502 timespan: see 'count'.
509 biolimit: max character length of bio; 0 means no limit; null means to use
510 the site text limit default.
511 backup: whether users can backup their own profiles. Defaults to true.
512 restore: whether users can restore their profiles from backup files. Defaults
514 delete: whether users can delete their own accounts. Defaults to false.
515 move: whether users can move their accounts to another server. Defaults
521 Options with new users.
523 default: nickname of a user account to automatically subscribe new
524 users to. Typically this would be system account for e.g.
525 service updates or announcements. Users are able to unsub
526 if they want. Default is null; no auto subscribe.
527 welcome: nickname of a user account that sends welcome messages to new
528 users. Can be the same as 'default' account, although on
529 busy servers it may be a good idea to keep that one just for
530 'urgent' messages. Default is null; no message.
532 If either of these special user accounts are specified, the users should
533 be created before the configuration is updated.
538 The software lets users upload files with their notices. You can configure
539 the types of accepted files by mime types and a trio of quota options:
540 per file, per user (total), per user per month.
542 We suggest the use of the pecl file_info extension to handle mime type
545 supported: an array of mime types you accept to store and distribute,
546 like 'image/gif', 'video/mpeg', 'audio/mpeg', etc. Make sure you
547 setup your server to properly recognize the types you want to
549 uploads: false to disable uploading files with notices (true by default).
550 filecommand: The required MIME_Type library may need to use the 'file'
551 command. It tries the one in the Web server's path, but if
552 you're having problems with uploads, try setting this to the
553 correct value. Note: 'file' must accept '-b' and '-i' options.
555 For quotas, be sure you've set the upload_max_filesize and post_max_size
556 in php.ini to be large enough to handle your upload. In httpd.conf
557 (if you're using apache), check that the LimitRequestBody directive isn't
558 set too low (it's optional, so it may not be there at all).
560 file_quota: maximum size for a single file upload in bytes. A user can send
561 any amount of notices with attachments as long as each attachment
562 is smaller than file_quota.
563 user_quota: total size in bytes a user can store on this server. Each user
564 can store any number of files as long as their total size does
565 not exceed the user_quota.
566 monthly_quota: total size permitted in the current month. This is the total
567 size in bytes that a user can upload each month.
568 dir: directory accessible to the Web process where uploads should go.
569 Defaults to the 'file' subdirectory of the install directory, which
570 should be writeable by the Web user.
571 server: server name to use when creating URLs for uploaded files.
572 Defaults to null, meaning to use the default Web server. Using
573 a virtual server here can speed up Web performance.
574 path: URL path, relative to the server, to find files. Defaults to
575 main path + '/file/'.
576 ssl: whether to use HTTPS for file URLs. Defaults to null, meaning to
577 guess based on other SSL settings.
578 filecommand: command to use for determining the type of a file. May be
579 skipped if fileinfo extension is installed. Defaults to
581 sslserver: if specified, this server will be used when creating HTTPS
582 URLs. Otherwise, the site SSL server will be used, with /file/ path.
583 sslpath: if this and the sslserver are specified, this path will be used
584 when creating HTTPS URLs. Otherwise, the attachments|path value
590 Options for group functionality.
592 maxaliases: maximum number of aliases a group can have. Default 3. Set
593 to 0 or less to prevent aliases in a group.
594 desclimit: maximum number of characters to allow in group descriptions.
595 null (default) means to use the site-wide text limits. 0
597 addtag: Whether to add a tag for the group nickname for every group post
598 (pre-1.0.x behaviour). Defaults to false.
603 oEmbed endpoint for multimedia attachments (links in posts). Will also
604 work as 'oohembed' for backwards compatibility.
606 endpoint: oohembed endpoint using http://oohembed.com/ software. Defaults to
607 'http://oohembed.com/oohembed/'.
608 order: Array of methods to check for OEmbed data. Methods include 'built-in'
609 (use a built-in function to simulate oEmbed for some sites),
610 'well-known' (use well-known public oEmbed endpoints),
611 'discovery' (discover using <link> headers in HTML), 'service' (use
612 a third-party service, like oohembed or embed.ly. Default is
613 array('built-in', 'well-known', 'service', 'discovery'). Note that very
614 few sites implement oEmbed; 'discovery' is going to fail 99% of the
620 Some stuff for search.
622 type: type of search. Ignored if PostgreSQL or Sphinx are enabled. Can either
623 be 'fulltext' or 'like' (default). The former is faster and more efficient
624 but requires the lame old MyISAM engine for MySQL. The latter
625 will work with InnoDB but could be miserably slow on large
626 systems. We'll probably add another type sometime in the future,
627 with our own indexing system (maybe like MediaWiki's).
634 handle: boolean. Whether we should register our own PHP session-handling
635 code (using the database and memcache if enabled). Defaults to false.
636 Setting this to true makes some sense on large or multi-server
637 sites, but it probably won't hurt for smaller ones, either.
638 debug: whether to output debugging info for session storage. Can help
639 with weird session bugs, sometimes. Default false.
644 Users can upload backgrounds for their pages; this section defines
647 server: the server to use for background. Using a separate (even
648 virtual) server for this can speed up load times. Default is
649 null; same as site server.
650 dir: directory to write backgrounds too. Default is '/background/'
651 subdir of install dir.
652 path: path to backgrounds. Default is sub-path of install path; note
653 that you may need to change this if you change site-path too.
654 sslserver: SSL server to use when page is HTTPS-encrypted. If
655 unspecified, site ssl server and so on will be used.
656 sslpath: If sslserver if defined, path to use when page is HTTPS-encrypted.
661 Using the "XML-RPC Ping" method initiated by weblogs.com, the site can
662 notify third-party servers of updates.
664 notify: an array of URLs for ping endpoints. Default is the empty
665 array (no notification).
670 Default design (colors and background) for the site. Actual appearance
671 depends on the theme. Null values mean to use the theme defaults.
673 backgroundcolor: Hex color of the site background.
674 contentcolor: Hex color of the content area background.
675 sidebarcolor: Hex color of the sidebar background.
676 textcolor: Hex color of all non-link text.
677 linkcolor: Hex color of all links.
678 backgroundimage: Image to use for the background.
679 disposition: Flags for whether or not to tile the background image.
684 Configuration options specific to notices.
686 contentlimit: max length of the plain-text content of a notice.
687 Default is null, meaning to use the site-wide text limit.
689 defaultscope: default scope for notices. If null, the default
690 scope depends on site/private. It's 1 if the site is private,
691 0 otherwise. Set this value to override.
696 Configuration options specific to messages.
698 contentlimit: max length of the plain-text content of a message.
699 Default is null, meaning to use the site-wide text limit.
705 Configuration options for the login command.
707 disabled: whether to enable this command. If enabled, users who send
708 the text 'login' to the site through any channel will
709 receive a link to login to the site automatically in return.
710 Possibly useful for users who primarily use an XMPP or SMS
711 interface and can't be bothered to remember their site
712 password. Note that the security implications of this are
713 pretty serious and have not been thoroughly tested. You
714 should enable it only after you've convinced yourself that
715 it is safe. Default is 'false'.
720 If an installation has only one user, this can simplify a lot of the
721 interface. It also makes the user's profile the root URL.
723 enabled: Whether to run in "single user mode". Default false.
724 nickname: nickname of the single user. If no nickname is specified,
725 the site owner account will be used (if present).
730 We put out a default robots.txt file to guide the processing of
731 Web crawlers. See http://www.robotstxt.org/ for more information
732 on the format of this file.
734 crawldelay: if non-empty, this value is provided as the Crawl-Delay:
735 for the robots.txt file. see http://ur1.ca/l5a0
736 for more information. Default is zero, no explicit delay.
737 disallow: Array of (virtual) directories to disallow. Default is 'main',
738 'search', 'message', 'settings', 'admin'. Ignored when site
739 is private, in which case the entire site ('/') is disallowed.
744 Options for the Twitter-like API.
746 realm: HTTP Basic Auth realm (see http://tools.ietf.org/html/rfc2617
747 for details). Some third-party tools like ping.fm want this to be
748 'Identi.ca API', so set it to that if you want to. default = null,
749 meaning 'something based on the site name'.
754 We optionally put 'rel="nofollow"' on some links in some pages. The
755 following configuration settings let you fine-tune how or when things
756 are nofollowed. See http://en.wikipedia.org/wiki/Nofollow for more
757 information on what 'nofollow' means.
759 subscribers: whether to nofollow links to subscribers on the profile
760 and personal pages. Default is true.
761 members: links to members on the group page. Default true.
762 peopletag: links to people listed in the peopletag page. Default true.
763 external: external links in notices. One of three values: 'sometimes',
764 'always', 'never'. If 'sometimes', then external links are not
765 nofollowed on profile, notice, and favorites page. Default is
771 These are some options for fine-tuning how and when the server will
774 shortener: URL shortening service to use by default. Users can override
775 individually. 'internal' by default.
776 maxurllength: If an URL is strictly longer than this limit, it will be
777 shortened. Note that the URL shortener service may return an
778 URL longer than this limit. Defaults to 100. Users can
779 override. If set to 0, all URLs will be shortened.
780 maxnoticelength: If a notice is strictly longer than this limit, all
781 URLs in the notice will be shortened. Users can override.
782 -1 means the text limit for notices.
787 We use a router class for mapping URLs to code. This section controls
788 how that router works.
790 cache: whether to cache the router in memcache (or another caching
791 mechanism). Defaults to true, but may be set to false for
792 developers (who might be actively adding pages, so won't want the
793 router cached) or others who see strange behavior. You're unlikely
794 to need this unless you're a developer.
799 Settings for the HTTP client.
801 ssl_cafile: location of the CA file for SSL. If not set, won't verify
802 SSL peers. Default unset.
803 curl: Use cURL <http://curl.haxx.se/> for doing HTTP calls. You must
804 have the PHP curl extension installed for this to work.
805 proxy_host: Host to use for proxying HTTP requests. If unset, doesn't
806 do any HTTP proxy stuff. Default unset.
807 proxy_port: Port to use to connect to HTTP proxy host. Default null.
808 proxy_user: Username to use for authenticating to the HTTP proxy. Default null.
809 proxy_password: Password to use for authenticating to the HTTP proxy. Default null.
810 proxy_auth_scheme: Scheme to use for authenticating to the HTTP proxy. Default null.
815 default: associative array mapping plugin name to array of arguments. To disable
816 a default plugin, unset its value in this array.
817 locale_path: path for finding plugin locale files. In the plugin's directory
819 server: Server to find static files for a plugin when the page is plain old HTTP.
820 Defaults to site/server (same as pages). Use this to move plugin CSS and
822 sslserver: Server to find static files for a plugin when the page is HTTPS. Defaults
823 to site/server (same as pages). Use this to move plugin CSS and JS files
825 path: Path to the plugin files. defaults to site/path + '/plugins/'. Expects that
826 each plugin will have a subdirectory at plugins/NameOfPlugin. Change this
827 if you're using a CDN.
828 sslpath: Path to use on the SSL server. Same as plugins/path.
833 high: if you need high performance, or if you're seeing bad
834 performance, set this to true. It will turn off some high-intensity code from
840 enabled: enable certain old-style user settings options, like stream-only mode,
841 conversation trees, and nicknames in streams. Off by default, and
842 may not be well supported in future versions.
