Log Message:
Fix SF bug #227748.
When using the flat-file back end, page names with slashes in them didn't work.
We fix this by urlencoding '%' '/' '\\' and ':' when they occur in page names.
WARNING: If any pages currently in your flat-file database contain any of
those characters in their titles, this change will make them invisible
to PhpWiki. You should back them up before upgrading, and restore them
after upgrading.

+ Flat File
+ 
+ We are now (since 1.2.0) urlencoding the characters '%', '/', '\\',
+ and ':' when forming filenames from page names. (This is to fix a bug
+ having to do with page names containing slashes.) If you currently have
+ any page names with any of those special characters, they will not be
+ visible to PhpWiki after you upgrade. (Any pages without those funny
+ characters in their names will be unaffected.)
+ 
+ If you do have pages with slashes, colons or percent signs in their names,
+ you should probably make a backup dump of your database before upgrading
+ and re-load the database after upgrading.

MySQL
 The MySQL schema has changed since PhpWiki 1.2.0.
 If you're upgrading from PhpWiki 1.2.0 and you use the MySQL back end,
 you need to update the schema.
 As long as you use the stock table names you can just do something like:
 mysql -u <username> -p wiki < schemas/update.mysql.1.2.0-1.2.1
 If you don't use the stock table names, look at the script in
 schemas/update.mysql.1.2.0-1.2.1 and use it as a guide.

	db_filesystem.php 
Log Message:
Attempt to fix SF bug #413446.
I think this bug was due to using PHP's file() function to slurp in the
files (as an array of lines). The files, being serialized data, consist
of only one (sometimes very long) line. I think (at least in some PHPs)
this make the file() function unhappy. 
Fixed to use fread() rather than file(). Also make sure to open files
in 'binary' mode.

Log Message:
Added real back-link searches.
The pgsql and msql backends are completely untested at this point,
but they "should work". (I.e.: they're probably broken now.)
The msql back-link search is a bit buggy, and will not find links
if they are split between two records ("lines") in the page store.
(The proper remedy for this is to implement the links table in
the msql back end.)

Modified Files:

Log Message:
Added support for bogo-logins.
One can now "login" using any WikiWord as a user ID.
(Unless logging in as the admin user, any password will work.)
Currently, the sole effect of logging in is that the
the logged-in user ID is recorded as the author of any
page edits. Thus, "logging in" allows one to control
the author which appears in RecentChanges and the page
info display.

Update of /cvsroot/phpwiki/phpwiki/lib
In directory usw-pr-cvs1:/tmp/cvs-serv31972
Added Files:
	PhpWikiDatabase.php 
Log Message:
Initial file for an abstract base class. For now I copy/pasted the
methods suggested in WikiDatabase
(http://phpwiki.sourceforge.net/phpwiki/index.php) as a starting
point, though there were a few that were undecided and I left those
out.
At least for now the class can support retrievePage() and insertPage()
and a few other basic methods, so rudimentary work can start.
The flowerbox reads:
/* 
 * Abstract base class for the database used by PhpWiki.
 * This should be extended by classes for DB/dbx, dba and 
 * flat file.
 */
