=head1 NAME

config.pod - documents BSE configuration file options

=head1 DESCRIPTION

BSE historically used Constants.pm to keep most configuration
information.  The plan is to make sure any new configuration is kept
in bse.cfg, and to slowly move most configuration information into
bse.cfg.

Keeping configuration information in Constants.pm makes it difficult
to perform upgrades and makes it impossible to use tools such as
mod_perl, at least if you want more than one site on the machine.

F<bse.cfg> is read as a utf-8 encoded file.

=head1 CONFIGURATION ENTRIES

=head2 [site]

Contains URL configuration for the site.

=over

=item url

The normal URL for the non-secure parts of the site.

=item secureurl

The secure URL for the shop, products and other portions of the site
that should use SSL.  This isn't checked to make sure it is https.

=item name

Used as the site "name" in a few places.

=item adminurl

If set, this is used as the base URL for accessing the administrative
functions of your site.

=item secureadmin

Ignored if C<adminurl> is set.

If this is true then C<secureurl> is used as the base URL for
accessing the administrative functions of your site, otherwise C<url>
is used as the base URL.  Default: false (C<url>'s value is used)

=item forward_from

Configure the IP address of one or more front-end proxies.  This can
be a regular expression except that C<.> is translated to C<\.> and
C<*> is tranlated to C<.*> to give more glob() like matching.

If the reqesting host matches then admin site URL matching is done
against HTTP_X_FORWARDED_SERVER instead of SERVER_NAME.

Default: no front-end server configured.

=item secret

A secret used (currently) for hashing cookie values passed between the
secure and non-secure parts of the site.  This must be set.  A
suitable value can be created with:

  openssl rand -base64 32

Contains various file system paths.

=over

=item downloads

completely implemented for now, so assume the default.  Default: admin
directory under $TMPLDIR.

=item templates

Directory base for most templates.  This can contain references like
$(section/key) to other configuration entries.  Split on the systems
PATH separators (run: perl -V:path_sep)

=head2 [extensions]

This section is used by the file wizard to map uploaded file
extensions to MIME content types.  This can be used to extend
BSE::FileEditor's internal extension map.  It cannot override that
map.

The key for each entry is the extension, without the leading '.'.

eg.

  xls = application/msexcel

The value of the charset keyword when outputting HTML from a script.
Set to the empty string to suppress the charset keyword.  Default:
iso-8859-1.

=item redirect_links

If this is a non-zero number, then all but mailto links are redirected
to C<nuser.pl/redirect> so you can display a diclaimer.  If this
contained alphabetics it's treated as a comma separated list of url
schemes that should be handled via C<nuser.pl/redirect>.  If 0 or not
present, no redirection is done.

The redirect URL includes a hash of the url, title and the redirect
salt to prevent using this mechanism by external sites for cookie
stealing attacks.

=item redirect_salt

The salt used in generating the has for redirect_links.  Default: an
empty string.

stepchildren on the article edit pages are filtered for access control.
Default: False.

=item alias_prefix

The prefix applied to articles that use a linkAlias url.  This should
start with a /.

=item alias_recursive

If this is non-zero then the link is formed by the C<alias_prefix>,

from the section, followed by the C<alias_suffix>.  You may need to
change your redirect handling if you enable this.  Default: Off.

=item alias_suffix

If this is non-zero then the title is cleaned up (all but
alphanumerics removed) and appended to the alias URL generated.

=item all_dynamic

If true then all articles are treated as dynamic.  Default: false.

=item auto_images

By default, if the author doesn't use any image tags, BSE will insert
any unnamed article images into the body text of an article.  You can
disable this on a per-article basis in the image tool, or disable it
globally by setting C<auto_images> to 0.

An alternative is to set C<imagePos> in C<[article defaults]> to
C<xx> which will default articles to not auto-inserting images.

=item cache_templates

If true, BSE will cache compiled templates using the configured BSE
cache, if any.  Depending on the configured cache this may slow things
down.  Default: disabled.

=item cache_templates_locally

If true, BSE will cache compiled templates in memory.  This may
significantly improve performance but may increase memory use.
Default: disabled.

=item cache_thumbnails

If set to zero the results of the thumbimage/gthumbimage body/template
tags will not be cached.  Default: 1 (caching is enabled).

=item cookie_domain

This overrides the domain value set for cookies.  This is useful if
you allow the site to run under both example.com and www.example.com,
if you set cookie_domain to example.com then a user visiting
www.example.com will still have their cookies when they visit
example.com.

=item cookie_lifetime

The expiry time for cookies.  This should be in the form supported by
CGI.pm for the -expires parameter.  Typically you want a plus ('+'), a
number, and a time character (s - seconds, m - minutes, h - hours, d -
days, M - months).  Set to an empty string for session cookies.
Default: +3h

=item cookie_name

This overrides the cookie name used to store the session id.  Default:
sessionid.  This is useful when you have 2 sites under the same
top-level domain, and helps disambiguate the cookie returned by the
browser.

The name of the custom class for your site.  This is currently only
used for article editing customizations.  This class should derive
from BSE::CustomBase.  Default: BSE::Custom.

=item default_popupimage

This is the default popup image class for the popimage[] and
gpopimage[] tags.  Default: popup.

=item dynamic_access_filter

If set to 0, dynamic article iterators will no access control filter
their results.  Default: 1.

=item error_not_defined

If non-zero, during dynamic page generation, inserts a message
explaining which variable is not set, instead of just leaving the tag
unreplaced.  Default: 1.

=item http_only_session

If this is non-zero, the default, the session cookie sent to the
browser has the C<HttpOnly> attribute set.  This can prevent session
cookie hijacking.  Default: 1.

=item htusers

This should be the path to a file to be updated with the list of users
and crypt() versions of their passwords.  If this is set then the
security system will check for a user set by the browser before
attempting a form based logon.  Default: None.

=item index_file

The name of the file to generate for static articles when the link is
terminated by "/".  Default: C<index.html>.

=item jit_dynamic_pregen

If this is true, then pre-generation for dynamic pages will be delayed
until the page is displayed to a user.  Default: off.

=item link_titles

If this is true then the links to your articles within BSE will be
followed by a / and then by a simplified version of the article title.
The aim is to include at least some title information in the URL
without modifying the name of the HTML file.  Default: False.

=item make_userid_cookie

If this is non-zero, the default, then when the site member logs in, a
javascript visible cookie, C<userid> will be set that contains the
login name of the user.  BSE's back-end doesn't use this cookie, its
only use is for Javascript to enable/disable user interface elements.
Default: 1.

=item minpassword

Previously the minimum length of site user passwords in characters.
You must now set C<length> in C<[siteuser passwords]>.

=item no_cache_dynamic

If non-zero, the default, dynamic responses will include a
C<Cache-Control: no-cache> header.  This can be overridden for
articles via , article flags, C<[template >
I<templatename>C<].no_cache_dynamic> and [article].no_cache_dynamic.
Default: 1.

=item preload_template

Preload the named template, searching the template search part.  Any
text that would normally be produced by the preloaded template is
ignored.  This can be useful for common definitions and variables for
use in many templates.  Default: none.

=item randomdata

Device to read random data from.  This device should not block when it
runs out of entropy.

=item redir_to_alias

If true then page.pl will 301 redirect (Moved Permanently) requests
for an article by its id to the generated link if the article has a
link alias.  Default: false.  Must only be used with use_alias true.

=item secure_session

If this is non-zero then the session cookie sent to the browser has
the C<Secure> attribute set.  This means that the cookie will only be
visible over https.  This is only useful when the only URL the site is
visited over is a https URL.  Default: 0.

=item server_auth

Set this to non-zero to enable authentication via server
authentication (usually Basic Authentication.)  You should normally
set this if you set htusers below.  Default: 0 (disabled)

=item sign

If this is true then the encrypted messages containing the customer's
credit card number are sent to the shop owner signed.  To avoid
keeping a passphrase and signing key on the server you can set this to
false (0).  This has the effect that anyone could send you an unsigned
message encrypted with your public key, though this may not be a
security threat.  Default: True.

=item staticajax

If true, the ifAjax and ajax tags will be active for static pages.

=item static_thumbnails

If true and cache_thumbnails is true then thumbnails for the thumbnail
cache will be generated when a static page is regenerated, and the
link from the page will link to the image in the cache rather than to
C<thumb.pl>.  Default: 1 (static thumbnails enabled).

=item track_uploads

If this is non-zero, and a cache is configured (see [cache]), file
uploads are tracked in entries in the cache.

The fileprogress.pl script can be called by Ajax to display file
upload progress information to the user.  The upload state is updated
a maximum of once a second.

=item use_alias

If this is non-zero then an article with linkAlias set will use an
alias url instead of the "real" url.  You will need to configure a
RewriteRule or ErrorDocument to page.pl to direct the user to the
correct URL.  Default: 1.

=item html_system_email

If non-zero then emails sent via the compose mail system that aren't
being sent to a member record, will be sent as HTML, if the HTML
template is available.

=item inline_css

If this is C<style> (the default) then use CSS::Inliner to attempt to

HTML.

If this is C<force> then we always attempt to inline CSS.

If this is any other value then don't inline CSS.

=item inline_css_flags

A comma separated list of flags to supply to CSS::Inliner->new().
Reasonable flags are C<strip_attrs> to strip C<id> and C<class>
attributes, and C<leave_style> to leave the HTML style block in place.

Default: no flags.

=item inline_css_report

If this is true and CSS inlining fails, log an error to the audit

When a user logs on, and the site url is different to the secure url
BSE attempts to refresh to the other "side" of the site to set the

BSE does some simple comparisons to attempt to determine whether the
logon form was triggered on the secure side of the site (possibly from
the shop) or on the insecure side.  Since CGI doesn't necessarily give
us all the information required, it's possible it will guess wrong.

Setting this option to 1 will enable debugging information sent to
standard error, which will be sent to the error log on Apache.  This
probably isn't useful on IIS.

=item file_unlink

Reports errors to STDERR (hence to the error log on Apache) if there
is a problem deleting the actual file when an attached file is
removed.

=item mail_encryption

Reports debugging information to standard error while encrypting your

STDERR.

=item ifUserCan

If non-zero then the ifUserCan tag will output some trace information
to STDERR.

=item trace_noimpl

Enables some trace messages from tags that return an ENOIMPL
exception.  This can be useful for tracking down why a tag isn't being
replaced.  This will produce a lot of output during page regeneration.

proportionally based on the source image size.

=item *

<size> - the desired maximum size in both directions. so "200" is
equivalent to "200x200"

=back

The crop flag is a single letter "c", if present then the image should
be scaled so the smaller dimension matches the requested size, and the
longer dimension will be cropped to fit.

The fill if present is: fill(color) where color is a color recognized
by the underlying graphics implementation.  This should be at least
hex web colors without the #, eg fill(FF0000) will fill with red.

C</cgi-bin/>I<script>C<.pl>.

The string C<TARGET> is replaced with the target specified in the
dyntarget tag.

This, along with dyntarget is intended to allow a more "Web 2.0" type
of access to BSE.  eg. you might set:

  [targets]
  shop=/xshop/TARGET
  shop_x=/xshop/

and have a rewrite rule:

  RewriteRule ^/xshop/(.*)$ /cgi-bin/nuser.pl/shop/$1 [PT]

=head2 [popimage class I<classname>]
