sa-compile - compile SpamAssassin ruleset into native code
sa-compile [options] Options: --list Output base string list to STDOUT --sudo Use 'sudo' for privilege escalation --keep-tmps Keep temporary files instead of deleting -C path, --configpath=path, --config-file=path Path to standard configuration dir -p prefs, --prefspath=file, --prefs-file=file Set user preferences file --siteconfigpath=path Path for site configs (default: /etc/mail/spamassassin) --updatedir=path Directory to place updates (default: /var/lib/spamassassin/compiled/<perlversion>/3.003002) --cf='config line' Additional line of configuration -D, --debug [area=n,...] Print debugging messages -V, --version Print version -h, --help Print usage message
sa-compile uses "re2c" to compile the site-wide parts of the SpamAssassin ruleset. No part of user_prefs or any files included from user_prefs can be built into the compiled set. This compiled set is then used by the "Mail::SpamAssassin::Plugin::Rule2XSBody" plugin to speed up SpamAssassin's operation, where possible, and when that plugin is loaded. "re2c" can match strings much faster than perl code, by constructing a DFA to match many simple strings in parallel, and compiling that to native object code. Not all SpamAssassin rules are amenable to this conversion, however. This requires "re2c" (see ""), and the C compiler used to build Perl XS modules, be installed. Note that running this, and creating a compiled ruleset, will have no effect on SpamAssassin scanning speeds unless you also edit your "v320.pre" file and ensure this line is uncommented: loadplugin Mail::SpamAssassin::Plugin::Rule2XSBody
--list Output the extracted base strings to STDOUT, instead of generating the C extension code. --sudo Use sudo(8) to run code as 'root' when writing files to the compiled-rules storage area (which is "/var/lib/spamassassin/compiled/5.016/3.003002" by default). --quiet Produce less diagnostic output. Errors will still be displayed. --keep-tmps Keep temporary files after the script completes, instead of deleting them. -C path, --configpath=path, --config-file=path Use the specified path for locating the distributed configuration files. Ignore the default directories (usually "/usr/share/spamassassin" or similar). --siteconfigpath=path Use the specified path for locating site-specific configuration files. Ignore the default directories (usually "/etc/mail/spamassassin" or similar). --updatedir By default, "sa-compile" will use the system-wide rules update directory: /var/lib/spamassassin/compiled/5.016/3.003002 If the updates should be stored in another location, specify it here. Note that use of this option is not recommended; if sa-compile is placing the compiled rules the wrong directory, you probably need to rebuild SpamAssassin with different "Makefile.PL" arguments, instead of overriding sa-compile's runtime behaviour. --cf='config line' Add additional lines of configuration directly from the command-line, parsed after the configuration files are read. Multiple --cf arguments can be used, and each will be considered a separate line of configuration. -p prefs, --prefspath=prefs, --prefs-file=prefs Read user score preferences from prefs (usually "$HOME/.spamassassin/user_prefs") . -D [area,...], --debug [area,...] Produce debugging output. If no areas are listed, all debugging information is printed. Diagnostic output can also be enabled for each area individually; area is the area of the code to instrument. For more information about which areas (also known as channels) are available, please see the documentation at <>. -h, --help Print help message and exit. -V, --version Print sa-compile version and exit.
