Using the site-wide contact forms, any subjects with an '&' cannot be
deleted. Clicking delete for these subjects brings up the expected
action flow, however, confirming the delete does nothing. Subject still
exists.

It appears this issue might be linked with this one:
http://drupal.org/node/23685

A problem with mod_rewrite and not the actual contact module.

Redid how contacts work. It now references contacts by ID instead of
their category as the unique identifier. It also allows for contacts to
have weights, so that one may control where the contact will appear in
the listing.

Hi, 

0. You should keep all changes in one file, i.e. pake one patch, not
patch for every file
1. You should include changes for database/database.{mysql,pgsql}
2. IIRC auto_increment was depreciated, you should use db_next_id()
(but I see auto_increment in cvs...)
3. You use "WHERE cid = '%s'", but cid is integer so this should
probably be %d (although this probably would not break anything..)

Ok, I've taken your suggestions in, and i think I have it this time. Let
me know if this is a correct format for a patch. This only fixes the bug
of not being able to delete special characters.

Check your database updates, the UNIQUE fields don't look right
syntactically.

Ok, i apologize for the last upload. Pleasle ignore. I send the wrong
file. :-[. Anyway, here's a tested, tried, and correct patch.

+1 patch works great! Latest HEAD version applied with update.php works
great, modifies database correctly for MySQL (and PostgreSQL looks
correct as well) and contacts can now be deleted if they have '&' in
the subject. Also, dumped entire database and created from modified
database.mysql and everything works great. I'd say this patch is ready
to be committed!

Hi, patch does not applies to currect cvs anymore.

For the database.pgsql you need to remove (11) from int(11) and also
first "category" from UNIQUE line, so it looks like this:
CREATE TABLE contact (
  cid int NOT NULL,
  category varchar(255) NOT NULL default '',
  recipients text NOT NULL default '',
  reply text NOT NULL default '',
  UNIQUE (category),
  PRIMARY KEY (cid)
);

The updates are also not compatibile with postgres, but postgres
upgrade path is completly broken in cvs and I'll fix it later, so do
not pay attention to it.

Hello. Thanks for the feedback. I'm in the middle of fixing it, but i
have a question. You'll have to excuse my ignorance with PostGres, I'm
not as familiar with it as I am MySQL. With that said, I have a
question.....
I am trying to make my update where one does not lose data. However, in
PostGres, I have to make a seperate "temp" table before hand and then
copy the date over the the new table (cause i don't know the exact name
of the constraint to drop e.g. the primary key).  

Basically I'm asking if there is a better suggestion in which I doint
have to use a temp table, and i could just manipulate the original
table? Thanks.

------------------------------------------------------------------------

Also,

I created a temp name for my temp table. However, for prefix purposes,
should I enclose it? Example:

$temp_name = rand();
$res = db_query("SELECT * FROM $temp_name");
or
$temp_name = rand();
$res = db_query("SELECT * FROM {$temp_name}");

Thanks.

------------------------------------------------------------------------

Clarification:

$temp_name = rand();
db_query("CREATE TABLE $temp_name AS SELECT * FROM {contact}");
$res = db_query("SELECT * FROM $temp_name");
or
$temp_name = rand();
db_query("CREATE TABLE {$temp_name} AS SELECT * FROM {contact}");
$res = db_query("SELECT * FROM {$temp_name}");

"cause i don't know the exact name of the constraint to drop e.g. the
primary key

"
Yes, you know it, it's tablename_pkey. In this case it's contact_pkey.
You can drop it by dropping index with it's name (you could drop
constraint with it's name but it was not available in 7.2)
Adding a column and adding unique attribute is also doable without temp
table. You can look at (some) previous updates. But some of them are
incorrect ;)

By saying that I'll fix it later I meant that I want to introduce
function to modify tables and don't want to make temporary fixes now.

Thanks. yes, you're right. didn't know if that was universal across the
board though since that'st he default, but someone could give their
primary key constraint a diff. name.  But, with your comment, I'll wait
and let you take care of fixing my pgsql portion of my patch. Thanks for
your comments though, really helpful...and not confusing. :).
