[IMC-Docs] update: report about imc-brasil-tech's work on docs [2009-01-17]

[mike]

Nice work!

To make the TWiki installation read only, I would first of all make
sure the files under /data and /pub are read only on the file system.

Then look at the TWiki access control settings:

http://docs.indymedia.org/bin/view/Local/WebPreferences

and

http://docs.indymedia.org/bin/view/Main/WikiGroups

looking for:

#  Set DENYWEBCHANGE =
# Set ALLOWWEBCHANGE =


I guess that ALLOWWEBCHANGE = TWikiAdminGroup would do it, in the same
way that the front page is protected with ALLOWTOPICCHANGE. but I
can't be sure that the TWikiAdminGroup has been set up / restored
correctly as it seems to be empty.

Hope this helps.

> Yesterday gdm turned on the humus vserver backup from 2008-09-28 in strummer,
> kompost's colocation neighbour, and gave us access to it. We created an
> indymedia user to be used to work on the docs by the members of the
> collective. This user is going to expire on 2009-01-27.
>
> We thought we should concentrate our work on 2 things:
>
>  1. put the docs backup up, read-only; and
>  2. work towards backup update with non-corrupted data from humus latest
>  image, using the analisys of the generated lists and data.

> 1. Docs backup
> ==============
>
> After trying to understand the deepness of the TWiki config, we thought that
> instead of modifying the existing TWiki config by trying to disable logins and
> user creation, it would be better to create an empty instalation of foswiki[1]
> with no user info, just the data.
>
> So foswiki is installed and running with the docs backup in the usual address:
>
>  http://docs.indymedia.org/
>
> We did not migrate the users, so protected pages are not publicly available.
> One idea would be to find out how to prevent updates to the content in foswiki
> (that should be easier than with TWiki, as the commercial version is the only
> one they provide support) and copy the user's passwords in the image .htpasswd
> file, as it's not corrupted.
>
>
> 2. Docs backup update
> =====================
>
> We ran scripts to generate a list of files which differ between the backup
> and the image. The scripts and generated data are attached. Some numbers:
>
>  45473 inspected_files
>  832 inconsistent_files
>  800 inexistent_files
>  276 files with file system errors
>
> These contain all the files under docs.indymedia.org/ folder. The files under
> pub/ and data/ sum about 43.000 entries.
>
> Inconsistent files are those that exist in the backup but whose contents are
> different. They can either be updates or corrupted files. Inexistent files are
> those which exist in the image but not in the backup. They can also be either
> updates or corrupted files. File system errors prevented 276 files from being
> read. These should be the ones we would have to recover by hand from web or
> user's caches.
>
> We are working now on scripts to test the consistency of the files and copy
> newer data to the backup in order to obtain the most complete version
> possible, regarding the time, knowledge and data we have.
>
> We believe that in the next working session (which should happen tonight)
> we'll be able to create lists of definitely corrupted files and newer files
> which can be updated to the backup. That would allow writing a simple script
> which updates the image based on this list.
>
>
> Proposal for next Steps
> =======================
>
>  X. read-only backup: disable wiki updates and migrate users,
>  Y. backup update: finish the scripts to generate the lists,
>  Z. backup update: update the backup with newer files.
