NAME

       SVN::Hooks::UpdateConfFile - Maintain the repository configuration versioned.

VERSION

       version 1.19

SYNOPSIS

       This SVN::Hooks plugin allows you to maintain the repository configuration files under version control.

       The repository configuration is usually kept in the directory "conf" under the directory where the repository was created. In a brand new
       repository you see there the files "authz", "passwd", and "svnserve.conf". It's too bad that these important files are usually kept out of
       any version control system. This plugin tries to solve this problem allowing you to keep these files versioned under the same repository
       where they are used.

       It's active in the "pre-commit" and the "post-commit" hooks.

       It's configured by the following directive.

   UPDATE_CONF_FILE(FROM, TO, @ARGS)
       This directive tells that after a successful commit the file FROM, kept under version control, must be copied to TO.

       FROM can be a string or a qr/Regexp/ specifying the file path relative to the repository's root (e.g. "trunk/src/version.c" or
       "qr:^conf/(w+).conf$:").

       TO is a path relative to the "/repo/conf" directory in the server. It can be an explicit file name or a directory, in which case the
       basename of FROM is used as the name of the destination file.

       If FROM is a qr/Regexp/, TO is evaluated as a string in order to allow for the interpolation of capture buffers from the regular
       expression. This is useful to map the copy operation to a diferent directory structure. For example, this configuration
       "qr:^conf/(w+).conf$: => '$1.conf'" updates any .conf file in the repository conf directory.

       The optional @ARGS must be a sequence of pairs like these:

       validator => ARRAY or CODE
	   A validator is a function or a command (specified by an array of strings that will be passed to the shell) that will check the contents
	   of FROM in the pre-commit hook to see if it's valid. If there is no validator, the contents are considered valid.

	   The function receives three arguments:

	   A string with the contents of FROM
	   A string with the relative path to FROM in the repository
	   An SVN::Look object representing the commit transaction

	   The command is called with three arguments:

	   The path to a temporary copy of FROM
	   The relative path to FROM in the repository
	   The path to the root of the repository in the server
       generator => ARRAY or CODE
	   A generator is a function or a command (specified by an array of strings that will be passed to the shell) that will transform the
	   contents of FROM in the post-commit hook before copying it to TO. If there is no generator, the contents are copied as is.

	   The function receives the same three arguments as the validator's function above.

	   The command is called with the same three arguments as the validator's command above.

       actuator => ARRAY or CODE
	   An actuator is a function or a command (specified by an array of strings that will be passed to the shell) that will be invoked after a
	   successful commit of FROM in the post-commit hook.

	   The function receives the same three arguments as the validator's function above.

	   The command is called with the same three arguments as the validator's command above.

       rotate => NUMBER
	   By default, after each successful commit the TO file is overwriten by the new contents of FROM. With this option, the last NUMBER
	   versions of TO are kept on disk with numeric suffixes ranging from .0 to ".NUMBER-1". This can be useful, for instance, in case you
	   manage to commit a wrong authz file that denies any subsequent commit.

	       UPDATE_CONF_FILE(
		   'conf/authz' => 'authz',
		   validator	=> ['/usr/local/bin/svnauthcheck'],
		   generator	=> ['/usr/local/bin/authz-expand-includes'],
		   actuator	=> ['/usr/local/bin/notify-auth-change'],
		   rotate	=> 2,
	       );

	       UPDATE_CONF_FILE(
		   'conf/svn-hooks.conf' => 'svn-hooks.conf',
		   validator	=> [qw(/usr/bin/perl -c)],
		   actuator	=> sub {
				       my ($contents, $file) = @_;
				       die "Can't use Gustavo here." if $contents =~ /gustavo/;
				   },
		   rotate	=> 2,
	       );

	       UPDATE_CONF_FILE(
		   qr:/file(
+)$:' => 'subdir/$1/file',
		   rotate	=> 2,
	       );
