Warning: Current core (or exorcist perhaps) produces duplicate repligard table entries

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Hi,

for all of you who are using the latest Midgard tech on
productive servers: Be
aware that some part of the package produces duplicate
entries in the repligard
table.

Midgard Core DOES NOT handle this case correctly. Versions
before something
around 1.7.3 do just ignore the case leading to the actual
duplicates (which
breaks MidCOM owner privileges and other stuff done directly
after create()),
while newer versions prevent object creation in such a case
(detected by an
UNIQUE INDEX, this is almost as bad as it prevents object
creation for obscure
reasons to users).

I am encountering this problem on a regular basis on at
least one live site, but
have not yet found a way to reproduce.

I thus recommend against using this piece of software until
this situation is
resolved.

Specifically I officially remove any recommendation to
deploy and MidCOM 2.5 on
live sites until this is resolved. I cannot support any of
these combinations
until either the root of this problem is solved or at least
the core gets more
error-resilent in this matter. This includes any bug
reporting where either
MidCOM 2.5 or Midgard 1.7 is concerned. Such bugs will not
be rejected if any
hint is there that points me to the conclusion that the
mentioned bug may be the
root of this problem.

Details can be found at the Midgard Bug Report #118 [1]
which also contains a
script [2] usable to detect and remove these duplicates in
case you absolutely
have to deploy 2.5 somewhere.

Can you copy here some url which points to documentaion
which says that object 
and it's record is not created in such case?

You have been advertising just this as a solution in IRC.

Yes, I said about repligard's record not being created.
Because it doesn't matter what guid should be assigned for
object in such case.
If some guids for realm , id pair already exists then its
automagically assigned itself 
to newly created object's record. Thus , no action is
required here as long as MySQL 
prevents from duplicated records being created.

Great. You're reusing GUIDs possibly already in use in
other places. Welcome
Data Chaos. Go on, continue like this, and you'll have me
switch to another CMS
in not time.
