SVN::Hooks::UpdateConfFile(3) User Contributed Perl Documentation SVN::Hooks::UpdateConfFile(3)

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

version 1.34

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.

This directive makes that after a successful commit in which the file FROM, under version control, have been added or modified, its newest version is 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 must be a relative path indicating where the original file must be copied to below 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. Non-existing directory components of TO are automatically created.

Note that if the path doesn't exist the hook assumes that it should be a file. To make sure it's understood as a directory you may end it with a forward slash (/).

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 different 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.
remove => BOOL
By default, if FROM is deleted in the commit, nothing happens to TO. If you want to have the file TO removed from the repository when FROM is deleted, set this option to a true value such as '1'.

        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(\n+)$:' => 'subdir/$1/file',
            rotate       => 2,
            remove       => 1,
        );
