In my previous article, I provided a guided tour of the Bricolage installation process. If you followed along, you should now have a nice, functioning installation of Bricolage 1.8 all ready to go. But as Mr. Popeil used to say, "But wait, there's more!"
Like many other applications, Bricolage comes with a runtime configuration file. This file, named bricolage.conf, lives in the conf subdirectory of your Bricolage root. It contains a list of settings that tell Bricolage how to find things, how to connect to the database, which optional features to include, and other good stuff. This article provides a guided tour of all of the configuration settings in bricolage.conf to enable you to configure things exactly the way you need them, so that you can manage your sites more effectively with Bricolage.
The format of bricolage.conf, derived from the
Perl Cookbook, is quite simple. A directive
appears on a single line, followed by a space, an equal sign, and then the
value. Anything after a pound sign (
#) is a comment. Typical entries
look like this:
APACHE_BIN = /usr/local/apache/bin/httpd APACHE_CONF = /usr/local/bricolage/conf/httpd.conf LISTEN_PORT = 80 SSL_PORT = 443 SSL_ENABLE = No
Most bricolage.conf configuration options are one of two types:
Boolean values or strings. A Boolean configuration directive can be either
enabled or disabled, but you have several ways in which to do so. To enable a
Boolean directive, simply set its value to
(the number one). To disable it, set it to
(zero). String values follow the equal sign. They can be as long as necessary,
but cannot break across lines.
The first section of bricolage.conf configures Bricolage to use the Apache web server. Because Bricolage runs on top of Apache but uses its own startup scripts, it needs to know where to find Apache resources so that it can configure and start Apache properly. Bricolage's default method of dynamically configuring Apache therefore relies on these directives. The installation sets many of them for you, but not all, so it's worth it to have a look to see if you need to tweak any of them:
This directive tells Bricolage where to find your Apache httpd executable, which it uses to start itself up.
This directive points to the httpd.conf file. This, of course, is the famous Apache configuration file. It, too, needs configuration to run Bricolage (the Bricolage installer configures the default httpd.conf in the conf subdirectory of your Bricolage root directory), and Bricolage, in turn, uses this directive to tell httpd where to find the configuration file when it starts up.
This is the TCP/IP port on which Bricolage will listen for requests. It uses the HTTP standard port 80 by default, but you can change Bricolage to use another port if you already have another server listening on port 80.
This is the TCP/IP port on which Bricolage will listen for secure sockets layer (SSL) requests. It defaults to the standard HTTP SSL port 443, but again, you can change it to another port if something else is already using port 443. SSL is disabled by default, however, so read on for details on how to turn it on.
This directive turns on SSL support. You must have either
mod_sslor Apache-SSL installed and properly configured in your Apache server. Not quite a Boolean configuration directive, the possible values for
apache-ssl. SSL is a useful feature for keeping communications encrypted between the server and users' browsers.
By default, an SSL-enabled Bricolage installation uses SSL only for logging in to Bricolage and in the user profile (where users can change their passwords). Users can elect to encrypt all communications by checking the
Always use SSLcheckbox when logging in, but some security policies may require the encryption of all communications. In such cases, enable this Boolean directive to force the encryption of all communications between the Bricolage server and users' browsers.
These directives specify the location of your SSL keys. If you've configured
mod_sslor Apache-SSL, you should already be familiar with these files. They help to encrypt and decrypt requests between the server and the browser. If you use
make certificateto generate your SSL certificate during the Apache build process, by default your server key file will be server.key in the conf/ssl.key subdirectory of your Apache root directory, while the server public key file will be server.crt and in the conf/ssl.crt subdirectory. Bricolage uses these directives to set the Apache
SSLCertificateFiledirectives, respectively, in its dynamic configuration of Apache.
This directive roughly corresponds to the Apache httpd.conf
NameVirtualHostdirective. Set it to the IP address on which the Bricolage Apache server will listen for requests. If you have only one IP address on your server, the simplest thing to do is to leave this directive set to
*, which applies to all IP addresses. Again, Bricolage uses this directive in its dynamic configuration of Apache.
This is the virtual host name under which to run Bricolage. Bricolage requires a full host or virtual host to run and will use this directive to configure the virtual host dynamically. Leave it set to
_default_to use the default host name set in your httpd.conf file.
Bricolage uses Apache::ReadConfig to configure the httpd daemon. There is no httpd.conf include file. If you want to take control of your Bricolage Apache server by manually configuring it, enable this Boolean directive. It will generate a file, bric_httpd.conf, in the bricolage subdirectory of your temporary directory (see the TEMP_DIR directive for the location of the temporary directory). This file will contain all of the Apache configuration directives that Bricolage uses to configure Apache dynamically. Restarting Bricolage will rewrite this file, but if you want to use it and edit it manually, copy it to the conf subdirectory of your Bricolage root directory, disable the
MANUAL_APACHEdirective, and then change the section of the httpd.conf file that configures Bricolage from:
PerlPassEnv BRICOLAGE_ROOT PerlModule Bric::App::ApacheConfig
Include /usr/local/bricolage/conf/bric_httpd.conf PerlPassEnv BRICOLAGE_ROOT PerlModule Bric::App::ApacheStartup
Here /usr/local/bricolage/conf/bric_httpd.conf is the full path name to the newly generated bric_httpd.conf file. You can now tweak this file to your heart's content. Just be sure to generate a new one after each upgrade of Bricolage, as certain directives may change between releases.
These directives configure the system user and group used by Bricolage. They should contain the same value as the
Grouphttpd.conf directives, usually
www. Any files written to the file system by Bricolage will be owned by this user and group.
The next major section of the Bricolage configuration file configures the database. Bricolage uses PostgreSQL 7.3 or later for its data store. Connecting to that database requires several attributes, not least of which are the username and password. These are all set during installation, but it's worth being familiar with them in case things change down the line.
The name of the database that stores Bricolage's data. The installer will set this for you. The default value,
bric, works well in most situations, but it might be set to a different name if you entered one during installation, perhaps because you already had another database named
bric; Why would you want to do that? Perhaps you have multiple Bricolage installations on the same host. Another reason it might be different is that your ISP provides you with a single database that they name according to their own naming conventions. At any rate, you're unlikely to need to change the value of this directive.
The username that Bricolage will use when connecting to the database. Again, you are unlikely to need to change this directive, especially because, when Bricolage creates the database, it specifically assigns permissions for this user to access the appropriate tables, sequences, and such. Note that, for security reasons, you should never use the PostgreSQL superuser for this directive.
The password for the
DB_USERto use to connect to the PostgreSQL database. You'll need to change this directive if the password ever changes in the database. Depending on your PostgreSQL server's security model, it might not matter what the password is. For example, if the PostgreSQL is on the same host as your Bricolage server and trusts local users (the default configuration), it will ignore the password. Consult your PostgreSQL authentication settings (in the server's pg_hba.conf file) or check with your PostgreSQL DBA if you have questions.
This is the host name of your PostgreSQL server. If it's on the same host as your Bricolage server, it will likely be commented out, thereby letting Bricolage default to
localhost. Otherwise, it will be a different host name or IP address. Change this setting if ever your PostgreSQL server moves to a different host or has its host name or IP address changed.
The TCP/IP port on which your PostgreSQL server listens for connections. This directive will be commented out if you've installed PostgreSQL locally and you're using Unix sockets instead of TCP/IP for its connectivity (a good idea for security-conscious environments). It will also be commented out if Bricolage should use the default PostgreSQL port of 5432. Otherwise, if Bricolage must connect to the PostgreSQL server via TCP/IP on a port other than 5432, set this directive to the appropriate port number.
Bricolage stores a lot of files on your server's file system, generally in well-named directories below your Bricolage root directory. Sometimes you may want them installed elsewhere, perhaps for the purposes of conserving disk space or distributing I/O between different partitions. If you want to move any of these directories to a location other than that set by the installer, copy over any existing files to ensure that Bricolage continues to operate correctly.
Bricolage creates several temporary files as it runs, for its cache, user sessions, and the like. If you selected the
multioption when installing Bricolage, this directive will point to a directory named tmp under your Bricolage root. Otherwise, it will point to your system's global tmp directory.
The Bricolage UI uses HTML::Mason. All of the components to power the UI live in this directory, generally a subdirectory of your Bricolage root named comp. However, media files uploaded to Bricolage also go in this directory, which means that it can become quite large if you manage a lot of media documents. It might be useful, therefore, to move this directory to a separate partition.
Mason compiles the Bricolage UI components into object files and stores them in this directory. For the most part you don't need to worry about where these files live (the default is the data directory under the Bricolage root directory), although Bricolage will read from it quite a lot as it loads the object files into memory, so disk I/O is important. It's unlikely to grow too except...
This directive tells Bricolage where to store formatting templates, object files, and burned files that are ready for distribution. As such, it can also grow quite large, especially if you've published or previewed a lot of documents. Bricolage never deletes these files so that you always have a canonical directory of the distribution files output by Bricolage. However, the default location for the
BURN_ROOTis under the directory specified by the
MASON_DATA_ROOTdirective. If you encounter disk space problems, you might want to move this directory to another partition.
The Bricolage Mason burner is responsible for pushing documents through Mason formatting templates. If you're writing templates that output XML (and I'll demonstrate writing templates in a later article, so hang in there!), you might want to simplify things by using an XML::Writer object to generate the XML. Bricolage simplifies things by providing these directives to create a globally available XML::Writer object for use in all Mason templates.
Enable this Boolean directive to tell Bricolage to create an XML::Writer object that's globally available as
$writerto all Mason templates. Bricolage is smart enough to configure the XML::Writer object to output XML to Mason's buffer, so that you can even mix standard Mason output in your templates with XML::Writer output.
Use this directive to specify a list of options to pass to the XML::Writer constructor when
INCLUDE_XML_WRITERis enabled. This directive is a string containing a Perl expression to pass to XML::Writer. The XML::Writer documentation has the full list of possible parameters. Common parameters include
NEWLINESto trigger the output of new lines between XML elements, and
DATA_INDENTto indent nested XML elements by a certain number of characters.
Several configuration directives affect the behavior and security of the Bricolage authentication system. Bricolage handles its own authentication, storing passwords in the database as MD5-encrypted hashes and recording authentication in a browser cookie. In a security-conscious environment, it pays to be familiar with these directives and even to review their settings periodically.
This directive specifies the time-to-live, in seconds, for an authentication session. Each time an authenticated user sends a request to the server, the elapsed time resets to zero. You could therefore set
AUTH_TTLto 3600 seconds for a one-hour time-to-live, and a user would be able to use Bricolage all day, as long as each request was less than an hour apart (but she might have to re-authenticate after lunch). This directive is especially useful in environments where users access Bricolage from public workstations and forget to log out. The default value of 28800 (eight hours) is probably too long in a production environment.
Bricolage stores the user authentication session locally and keys it off of an MD5 string stored in a browser cookie. The MD5 string comes from the browser's IP subnet, the expiration time, the user name, and the last access time. Because such a string is potentially replicable by someone trying to crack the system, Bricolage also uses a random string of characters to salt the MD5 string.
AUTH_SECRETis the string used for this purpose. The installer generates it for you, but you might want to change it now and then, in order to keep it random and meet the specifications of your security policy. All users will need to re-authenticate after you change
AUTH_SECRETand restart Bricolage.
This directive specifies a minimum user name length. Each user must have a user name of at least this number of characters. The default,
5, is generally adequate, and allows the default
adminuser name to work properly.
This directive corresponds to the
LOGIN_LENGTHdirective, but applies to passwords. The password length in Bricolage is unlimited, but it's generally a good idea to ensure that they all contain a minimum number of characters. The default is
When Bricolage previews or publishes documents, it pushes them through formatting templates (written in Mason, Template Toolkit, or HTML::Template) and writes the resulting files to disk. It then distributes those files to the appropriate servers specified in the destination manager in the user interface. (A later article will explain more of the Bricolage administrative interface.) Many run-time configuration directives affect the behavior of the Bricolage distribution server.
This Boolean directive enables Bricolage distribution. The only reason to disable distribution is if you set up a separate distribution server. To my knowledge, no one has actually done this, even though Bricolage supports it. The QUEUE_PUBLISH_JOBS directive is more popular to reduce Bricolage server overhead.
Bricolage distributes files via file system copy, FTP, SFTP, or WebDAV—depending on your destination configuration. We all know that failures can occasionally occur. Bricolage will attempt to distribute a file after a failed distribution and will do it multiple times. Set the
DIST_ATTEMPTSdirective to the number of times it should attempt to distribute a file before giving up.
This Boolean directive enables Bricolage's internal preview server. This is just a URI in the Bricolage UI that knows to serve previewed content rather than the UI. This is handy for evaluating Bricolage, but be sure to disable it in a production environment, especially if your front-end server needs to serve something other than static HTML. The recommended approach is to set up a separate preview server that is identical to your production server and configure a destination to distribute and redirect previews to that server.
PREVIEW_LOCALdirective enabled, if the content you're generating includes Mason calls, you can enable this boolean directive to make Bricolage's internal preview server evaluate the Mason code before serving documents.
This string directive identifies the default media type (also called a
MIME type) of files for which Bricolage cannot determine the media type. The default value,
text/html, covers a lot of typical files in a Web content management environment, such as .php or .jsp files. To add new types for Bricolage to recognize, use the media type manager in the UI.
By default, Bricolage does not support distribution via secure FTP (SFTP). If you need it, install the required Net::SFTP module, enable this directive, and restart Bricolage.
If you've enabled SFTP distribution, use this directive specify a home directory for SFTP to use, especially if you want to use public and private SSH keys. Consult the Net::SFTP documentation for details.
Enable this directive to prefer SSH2 support for SFTP distribution. You'll also need to install more Perl modules from CPAN. Consult the Net::SFTP documentation for details.
Net::SFTP uses the Net::SSH::Perl module to handle the SSH side of things. This module supports multiple encryption ciphers. If you prefer one, specify it via this directive.
Bricolage also supports distribution via WebDAV, a standard for distributing documents via the HTTP protocol. DAV, as it is also known, has support in multiple web servers including Microsoft's IIS and Apache 2. If you'd like to distribute document files to your production server or servers via DAV, install the HTTP::DAV module, enable this Boolean directive and restart Bricolage.
By default, when a user schedules a document to publish immediately, the Bricolage server will immediately execute the distribution. If users publish a lot of documents or you're bulk publishing large sections of your site at once, this can really slow down the Bricolage UI for other users. This is even true even if you've scheduled a bulk of documents to publish at a future date and time, because the way the default bric_dist_mon script works is to tickle the Bricolage server to distribute documents.
The way around this problem is to enable the
QUEUE_PUBLISH_JOBSboolean directive and then use the bric_queued program instead of bric_dist_mon. With
QUEUE_PUBLISH_JOBSenabled, the Bricolage server will never burn and distribute documents, even if a user schedules them to publish yesterday. Instead, bric_queued handles all of the burning and distribution itself, without having the Bricolage server expend resources on the task. With this approach, be sure to run bric_queued from a fairly aggressive cron job.
When Bricolage distributes files via FTP, it uploads them with a temporary file name, and then, when the transfer is complete, it renames the file to the final name. However, if an earlier version of the file is already present, the rename might fail. (This depends on your FTP server, but Microsoft's IIS is the server that led us to add this feature.) In such a case, enable this directive and Bricolage will delete any existing instance of the file before renaming the temporary file.
Bricolage has an interface for sending alert emails when it logs events that meet certain criteria against objects. Bricolage needs to know a few things before it can send the alerts.
Bricolage uses an SMTP server to send alert email messages. The default value for this directive,
localhost, is fine if you use a Unix system with sendmail (or some other SMTP server) running locally. If your organization has a dedicated SMTP server or if your Bricolage host has none of its own, change the value of this directive.
Set this directive to an email address that you want to appear in the
Fromheader of alert emails. I typically set it to something like
Bricolage Admin <email@example.com>, but use whatever is appropriate for your organization. If your users are inclined to reply to alert emails, you may want to set up a special
ALERT_FROMemail address that has an auto-responder to let the user know that the reply will go unread.
This string directive indicates which header to use for specifying alert recipients in email alerts. The possible values are
Some configuration directives enable you to affect how the Bricolage user interface works in subtle ways. If you haven't used the Bricolage browser-based interface much yet, some of these won't make much sense just now. Feel free to come back and look again when you're you've had some experience with the Bricolage interface and want to make it behave more according to your own notions of correctness.
By default, when you search for objects in the Bricolage admin interfaces, or for stories, media, or templates in the asset library, the Bricolage UI appends a wildcard character to the end of your search string. Thus if you search for
foo, the search will return results for all records that start with
foo. If, however, you set the
FULL_SEARCHBoolean directive to a true value, all searches in the Bricolage UI will become substring searches. So a search for
foowill return all records where
fooappears anywhere in a record.
The downside to this approach is that it prevents PostgreSQL from using its database indexes. In principal, this is only a problem if you have a large number of objects in Bricolage. If, say, you had 100,000 stories in Bricolage, you would notice that story searches would be noticeably slower with
FULL_SEARCHenabled than with it disabled. Leave it disabled if you expect to manage a lot of documents. Your users can always manually prepend the wildcard character (
%) to the front of search queries if they want a substring search.
Bricolage workflows are made up of a series of desks. In general, workflows have their own desks, but desks can appear in more than one workflow. In such a case, documents moved to such a shared desk in one workflow will be visible on the same desk in another workflow. This is great for managing common tasks across workflows, such as translation or legal review. The upshot is that, by default, a document placed on a desk in one workflow cannot be transferred from that desk to another desk in a different workflow. Users can only move it to other desks in the workflow in which it originated. Set the
ALLOW_WORKFLOW_TRANSFERBoolean directive to a true value to remove this constraint, so that a document placed on a desk in one workflow can be moved from that desk to other desks in other workflows that the desk is in.
When managing multiple sites in Bricolage, the user interface will display a
site contextselect list. Only the workflows for the selected site will be displayed. If you want to allow users to see all of the workflows for all of the sites that they have permission to access, set this Boolean directive to a true value to add an
All Sitesoption to the
Site contextselect list. But beware! If you have access to a lot of sites, you'll have access to a bewildering number of workflows when you select this option!
For the input of dates in Bricolage, the user interface offers select lists for the day, month, and year. By default, the years available in the
Yearselect list have a limit of the ten years before and after the value for the year or the current year. If you need more years in your select list, set these directives to the number of years before and after the current value or current year. For example, if you manage a site of historical photographs with Bricolage, you might need to select years that range back over 100 years. In such a case, set
100. A science fiction book review site, on the other hand, might need years much farther in the future. For such a case, set
YEAR_SPAN_AFTERto the appropriately high number.
The file names generated for story documents are set on a per-output channel basis. The user interface offers default values for these settings in the output channel profile. The default file name is
index, and the default file name suffix is
html. If, say, you were outputing content to an IIS server, you might want to set the
htm, instead. It's not a big deal either way, though, because you can actually set the values you need for each output in the user interface. These are just the displayed defaults, settable as directives for the ultimate in laziness.
Document models are associated with output channels in Bricolage. When you create a new document based on a model, it will automatically have the output channel associations defined by the model. If you'd like users to be able to change the associations—say, to assign output channels defined by the model to be optionally associated with documents based on that model—set this directive to a true value. If, however, the added complexity of output channel associations will only confuse your users, set this directive to a false value to remove the user interface for changing document output channel associations.
When editing a story document in Bricolage, you'll see a select list of all categories that you have READ permission to access to allow you to optionally add the story to a new category. Most of the time, however, you'll only add a story to one or two categories, and then never change these settings. Therefore, if you have a lot of categories in your Bricolage installation (and there are systems in production with over 2000 categories), it's wasteful to load them all every time you edit a story document when you'll never change them again.
In such a case, set the Boolean
ENABLE_CATEGORY_BROWSERdirective to a true value and restart Bricolage. This will change the story profile to offer a link to a category browser, which enables you to search for the category or categories to associate with a story. Now, not only will you no longer load all categories every time you access the story profile (and the story profile is, for content producers, the most commonly accessed page in the Bricolage UI), but you'll only load those you search for in the category browser. I highly recommend that every Bricolage admin to set this directive to a true value.
These directives relate to how Bricolage manages documents.
Bricolage allows you to create relationships between documents. These can point to
related storiesor add images to a document, among other things. By default, when you publish a document, Bricolage will also try to publish any related documents. This will help to prevent 404s or broken image problems. In some cases, you might not want this behavior, so set the
PUBLISH_RELATED_ASSETSBoolean directive to a false value.
Story documents in Bricolage must have unique URIs. URIs consist of a story's category and optionally other parts of the story, such as its cover date and its slug (a one-word description of a story). They do not, however, consist of the file name. This is in keeping with W3C suggestions. The idea is that the story has a directory URI, and there may be several forms of the story with different file names in that directory, such as
rdf.xmlfor RDF, and
However, some organizations have Website policies that demand the inclusion of file names in the URI. This is so that different documents can be in the same directory. A common example might be a
About Usdirectory with separate
/about/copyright.htmldocuments. Such URIs are not possible by default in Bricolage, which requires that all stories have unique URIs, because each of these stories would have the same URI, namely
/about. To get around this issue, set the
STORY_URI_WITH_FILENAMEBoolean directive to a true value. From then on, all stories will include their file names in their URIs. Be careful, though! Existing stories will not have their URIs changed. Decide how you want to set this directive when you start using Bricolage, and never change it.
The URIs for story documents are determined by patterns specified on a per-output channel basis. There are two different URI formats in each output channel, one for fixed documents and one for non-fixed documents. Non-fixed documents typically use parts of the cover date in their URIs, while fixed URIs do not. Each document model has a flag set to indicate whether documents based on the model will use the fixed for non-fixed URI patterns. The result is that, for non-fixed stories, you might have URIs like
/reviews/books/2004/12/23/princess_bride. Here the URI format includes the slug, a one-word summary of the contents of a story (the
princess_bridepart of this example). However, slugs are optional in stories, even non-fixed stories. If you want to force all non-fixed stories to include the slug in order to guarantee the creation of more meaningful URIs, set this Boolean directive to a true value.
This Boolean directive complements the
ALLOW_SLUGLESS_NONFIXEDdirective. If you want to keep the slug optional but generate one when a user neglects to type one in, set
AUTOGENERATE_SLUGto a true value. This will cause Bricolage to generate a simple slug based on the title of the story. For example, a story with the title
Essential Perl 6would have the slug
essential_perl_6generated for it.
Bricolage is a large application that includes many CPAN modules as well as
its own 120,000+ lines of code. When you start it up, its processes can take up
30MB of memory or more. In general this isn't a problem, because Apache shares
that memory between child processes. As each process handles requests, however,
its size can swell independent of other processes. If you're performing
resource intensive activities, such as publishing a lot of documents at once,
the process that handles the request can become quite large. Because Perl (and,
mod_perl) does not return memory to the system, this
can give the appearance that you have a memory leak.
The solution to this problem is to use the Apache::SizeLimit module distributed with
mod_perl to check your
periodically and kill them when they exceed a certain size. Bricolage has
integrated support for Apache::SizeLimit that these directives can quickly
enable and configure.
This Boolean directive turns on the Apache::SizeLimit support. After you set it to a true value and restart Bricolage, it will use the settings in the following directives to decide how often to check your processes and to kill them when they get to be too big.
This is the maximum size, in bytes, that processes can reach before Apache::SizeLimit will kill them.
This directive determines how often Apache::SizeLimit will check the size of your
mod_perlprocesses. If you set it to
5, it will check a process after every fifth request handled by that process. The default is
This directive indicates the minimum amount of shared memory the process must employ to avoid being considered a candidate for termination. Consult the Apache::SizeLimit documentation for more information. The default is
0, meaning that all Apache
mod_perlprocesses will have their sizes checked.
This directive sets a limit on the amount of unshared memory a process may consume to not be a candidate for termination. You can use this directive to tweak your settings if you find that Apache::SizeLimit terminates processes while they are still mainly using shared memory. The default is
Bricolage pushes story documents through formatting templates to generate
output when you preview or publish them. Formatting templates can use Mason,
Template Toolkit, or HTML::Template. If you have a lot of different types of
story documents, or just elements of story documents, you'll likely end up with
a lot of templates to manage. Editing templates in the browser interface's
textarea fields can be a pain. A better approach is to use the
Bricolage virtual FTP server, which provides access to all Bricolage templates
via FTP. If the security of your password isn't a serious consideration
(because FTP sends passwords in the clear, and maybe you work behind a firewall
or over a virtual private network), enable the virtual FTP server and edit
Bricolage templates from within your favorite FTP-enabled editor (Emacs, Vim,
HomeSite, etc.). Here's how.
This boolean directive enables the virtual FTP server. Set it to a true value, tune the other FTP directives, reboot Bricolage, fire up the bric_ftpd application, and get to work! Just connect to your Bricolage FTP server on the port specified by the
FTP_PORTdirective, login with your Bricolage username and password, and you can browse templates by site, output channel, and category.
This directive specifies a TCP/IP port on which the Bricolage virtual FTP server will listen for connections. The default is
If your host has more than one IP address, specify one of them here to have the virtual FTP server to listen for connections on that IP address only. By default, the FTP server will listen on all of your host's IP addresses.
The location of the virtual FTP server log. By default, it will be in the log subdirectory of your Bricolage root directory.
Specify the location of the PID file for the Bricolage FTP server. bric_ftpd will use this file to record the PID of the server when you start it and to stop the server when you execute
bric_ftpd -k. The default is to store the PID file in the log subdirectory of your Bricolage root directory.
As of Bricolage 1.8 and later, the Bricolage FTP server will save templates to your private sandbox when you upload them. This means that they will be checked out to you, appear in your personal workspace in the UI, and execute when you (and only you) preview stories that use them. To check in and deploy a template to use in production when other users preview and publish documents, simply append the string .deploy to the end of the file name when you upload it and Bricolage will do the rest.
Prior to version 1.8.0, the Bricolage virtual FTP server checked out, updated, checked in, and deployed templates on every upload. If for some reason you prefer this approach (and to be honest, I can't imagine why anyone would!), set the
FTP_DEPLOY_ON_UPLOADdirective to a true value and restart bric_ftpd.
If for some reason the virtual FTP server isn't behaving the way you expect, set this Boolean directive to a true value and restart bric_ftpd. Then tail the FTP log (specified by the
FTP_LOGdirective) to diagnose the problem.
Because Bricolage runs on Apache 1.3, the parent process loads all of its code at startup time, before it forks off any children. This is memory efficient, because most modern operating systems use a copy-on-write forking design. This means that the children all share memory with the parent until they write to that memory, at which time the kernel copies that memory to the child process.
When loading a lot of code, children never overwrite much of it. It's highly advantageous to load as much code as you think you'll need into the parent process at startup time, to prevent each of the children from loading it themselves and taking up that much more memory. These directives help you to do just that.
This string directive can be any Perl code you like, as long as it's all on one line in the bricolage.conf file. Bricolage will execute this code at startup time, in the namespace used by the Mason burner. This is very useful for loading Perl modules that your templates use, so that you're not loading them in each child process. The default value loads Apache::Util, which has many useful HTML output utility functions, and Bric::Util::Burner, which exports several constants that you can use in templates to tell what type of burn is being executed (preview or publish). Other common modules you might want to load here include CGI.pm or XML::RSS to assist with HTML and RSS output, respectively. You can load anything here, really.
Bricolage has localizations for multiple languages, including German, Portuguese, Italian, Cantonese, Mandarin, and Russian. The localization libraries are Perl modules loaded at server startup time. For the most efficient use of memory, load the languages you expect to use most often by specifying the appropriate language codes (such as
de_defor German, etc.) in a space-delimited list via the
This directive functions just like the
LOAD_LANGUAGESdirective, except that it loads the libraries that convert to and from UTF-8. Bricolage allows individual users to use different character sets when accessing the Bricolage UI, including ISO-8859-1, ISO-8859-2, Big5, ShiftJIS, GB-2312, and others. To save memory overhead, specify each character set that you expect your users will need to use day-to-day in Bricolage in a space-delimited list in the
As of Bricolage 1.8.0, Bricolage can generate thumbnail versions of image files uploaded for media documents. All you need to do is install the Imager module from CPAN (along with the necessary libraries for the image formats you use—see the Imager README file for details) and configure thumbnail support via these directives.
Set this Boolean directive to a true value and restart Bricolage to have thumbnails generated for all image files in Bricolage. You must have Imager installed, of course. You might also want to consider installing media type icons specific to particular types of non-image files. See the README file and script in contrib/copy_gnome_icons in the Bricolage sources for information on which icon files to use and how to install them using the copy_gnome_icons script.
Set this directive to the maximum dimension of thumbnail images, in pixels. Bricolage will use this number to constrain the size of the thumbnail so that its greatest dimension does not exceed this number. For example, if
THUMBNAIL_SIZEhas its default value,
75, and you upload a 150 x 100 pixel image file, Bricolage will generate a 75 x 50 pixel thumbnail.
Bricolage 1.8.0 added support for WYSIWYG (what you see is what you get)
default. To enable it, download and install htmlArea 3.0 (in beta release as of
this writing) in the comp/media/htmlarea directory under your
Bricolage root. Then configure it via these directives and restart Bricolage.
You will then be able to specify a
WYSIWYG field type in document
element definitions, and content editors can take advantage of htmlArea's
WYSIWYG features when editing content in those fields.
Set this Boolean directive to a true value to enable Bricolage's htmlArea support. You must have htmlArea installed in the comp/media/htmlarea directory under your Bricolage root.
The htmlArea editor offers a lot of WYSIWYG features as controls (buttons) in its interface. The controls handle tasks such as copy, paste, italicize, boldface, link, etc. By default, Bricolage enables only a subset of these controls. The subset excludes layout type features such as font selection and color, line justification, and the like. The idea is to provide only the tools needed for users to easily add semantically meaningful markup rather than layout markup, so as to keep content independent of presentation. If you really need to allow your users to use six different type faces in twelve colors, you can enable the htmlArea controls for these features via the
HTMLAREA_TOOLBARdirective. The value of the directive is a comma-separated list of single-quoted strings with brackets at either end. See the htmlArea documentation for a complete list of supported controls.
Now you have all the information you need to configure how Bricolage operates to your heart's content. My next article will explore the nitty-gritty of defining document models in Bricolage.
