Foswiki Installation based on git

These instructions are more geared for developers, and admins who want to use the "bleeding edge" of Foswiki. We recommend using our packaged distributions. See our Download page

You can run a Foswiki instance from this clone simply by pointing Apache at it. See the ApacheConfigGenerator

Note:Configure has been completely rewritten on the master branch. Foswiki is now able to "bootstrap" itself without a configuration. After pseudo-installing the default extensions, Point your browser at your default URL for the new site as configured in ApacheConfigGenerator. (ex. http://yoursite.com, http://yoursite.com/foswiki, or http://yoursite.com/foswiki/bin/view depending upon the apache configuration)

To "install" extensions in a checkout area, you should use the pseudo-install.pl script to install them. On Unix/Linux this script generates soft-links from the core tree to the extensions, so you can work on your code in situ and see the impact of the changes on your live foswiki without needing to do an install step. Windows doesn't support soft links, so the script can also be run in -copy mode (the default on Windows), but in this case you will have to re-run it each time you change your extension. Use:

pseudo-install.pl default to install the default contribs and plugins (e.g. Extensions.TwistyContrib which is relied on by Extensions.PatternSkin)
pseudo-install.pl developer to install the additional developer extensions. The developer option also installs all the default extensions. See the header comment of the pseudo-install.pl script (core directory of checkout) for options and more information. Note that pseudo-install.pl only works with extensions that have a MANIFEST file, as required by the Extensions.BuildContrib.

Script examples below are for bash shell.

Example of running pseudo-install

The typical situation is that you want to run a pseudo-installed Foswiki checked out from "master" branch. And if you develop plugins, you want to be able to activate your plugin in this installation. This is the entire sequence for checking out the master branch from git and doing the pseudo-install. We assume that you want to run your git based install in /var/www/foswiki

The following commands check out an absolutely minimal Foswiki (the core + default user mapping only). This is the smallest checkout that will run. The steps are:

create the root directory called foswiki
git clone https://github.com/foswiki/distro.git foswiki
This will check out core and all the default and developer extensions, however they are not installed yet.
cd core && ./pseudo-install.pl default
change the ownership so the entire tree is owned by the user running the Apache. In this example the user name is "apache".
point Apache at the checkout Change the commands to fit your actual file locations and Apache user. Some commands may have to be run as root.

cd /var/www
mkdir foswiki

git clone https://github.com/foswiki/distro.git foswiki

Use the ApacheConfigGenerator
Clipboard copy and save this to core/../foswiki.httpd.conf
Include this foswiki.httpd.conf from your apache httpd.conf OR

On many linux distributions, you can save this file into /etc/apache2/sites_enabled or /etc/apache2/vhosts.d, or /etc/apache2/Include ... Check your local distribution's instructions.
If you are on a Mac, you can put this file into /etc/apache2/other/ and line "Include /private/etc/apache2/other/*.conf" will pick it up.
Otherwise, edit your httpd.conf and add: Include /path/to/foswiki.httpd.conf
Ensure your new .conf file has chmod a+r access Note: If the apache error log has lots of Symbolic link not allowed or link target not accessible type messages, then you probably need to add +FollowSymLinks to the Options for the /var/www/foswiki/dev/core/pub directory in your apache configuration.

At this point, if you point your browser to your foswiki url, it should "just work", but will display a bootstrap warning at the top of the configuration. To fully configure foswiki, visit the bin/configure URL, resolve any warnings and errors, and save the configuration. Caution: Once you save the configuration, you will be unable to use configure again unless you have registered and granted yourself "Adimin" authority. You can control who can use configure by setting Security and Authentication -> Access Control {ConfigureFilter}. When that option is set, it replaces the check for Admin authority and can allow any user including the guest user to use configure. So use caution!.

Now and then you will want to keep your installation in sync with the latest version in the foswiki git repository. The pseudo-install script is not intelligent enough to cope with changes to MANIFESTs, so this is the idiot proof way to update. It first removes all the links (or copied files), git fetch. And finally does a new pseudo-install.

cd /var/www/foswiki/core
./pseudo-install.pl -uninstall all
git pull
./pseudo-install.pl default
chown -R apache:apache ..

Normally just doing the git pull will be enough, unless someone has removed files (and even then you can usually ignore it).

If you are a developer you can also install the kit required to run unit tests, by passing the developer parameter to pseudo-install.pl

cd /var/www/foswiki/core
./pseudo-install.pl developer

This will also install BuildContrib and a number of other components useful to developers.

Tips, hints, and useful commands

Enable ASSERTS for more extensive testing

The unit tests run with ASSERTS enabled, but the live web environment does not. In order to enable ASSERTS, edit bin/LocalLib.cfg (If it's not there, create it by copying bin/LocalLib.cfg.txt) and un-comment the following line

$ENV{FOSWIKI_ASSERTS} = 1;

This enables additional validation tests that will impact performance, but will catch some issues that might be missed during normal web usage.

Use the CPAN modules shipped with Foswiki

Foswiki 1.2 no longer ships with CPAN modules. It is now recommended to use your system's package manager, or cpan to install dependencies. see http://foswiki.org/System/SystemRequirements. In the event that you are unable to install the CPAN dependencies, pseudo-install the CpanContrib to get the 1.x style Foswiki specific dependencies. (CpanContrib is not yet released). In order to test these modules, CPAN lib prepending should be enabled in bin/LocalLib.cfgby uncommenting the following line:

$CPANBASE = '';                     # Uncommented: Default path prepended

. See the comments in bin/LocalLib.cfg.txt for more details.

It is probably best to test using platform modules as well as the shipped modules.

Installing non-default extensions

The example commands above describe how to install a minimalist Foswiki. The pseudo-install script knows some additional tricks to use with non-default extensions. If you pseudo-install an extension that is not currently checked out, pseudo-install will automatically clone the extension from github using https://github.com/foswiki/ExtensionName.git

Note: Although we use release managed branches (master, Release01x00, Release01x01) in the Foswiki core distribution ("distro"), non-default extensions typically only have a "master" branch.

Here's how to install a non-default extension, using AntiWikiSpamPlugin as an example:

cd foswiki/core
 ./pseudo-install.pl AntiWikiSpamPlugin
Useless use of \E at ./pseudo-install.pl line 1553.

Delete all broken soft links

This is handy if you have changed a lot of MANIFESTS or have manually soft-linked any files, and want to remove any broken soft links. Assume your trunk checkout is at /var/www/foswiki. You'll also need to do this when switching between Release01x01 and master branches.

find -L /var/www/foswiki/core -type l -exec rm \{\} \;

Create a new extension

You can quickly and easily create a new extension using the create_new_extension.pl script that is installed in core when you pseudo-install the Extensions.BuildContrib.

Set up the unit test framework

If you are developing new code you will want to set up the development and test environment. For this you will need to pseudo-install !BuildContrib, !UnitTestContrib and !TestFixturePlugin.

./pseudo-install.pl developer

Then:

cd test/unit
export FOSWIKI_LIBS`/var/www/foswiki/core/lib
perl ../bin/TestRunner.pl FoswikiSuite

(or equivalent on Windows)
