Thanks Bradford,
That allowed me to track down the issue. It seems that when the PHP
classes serialize the document in json for saving the _rev is cast
to an
integer. The rev numbers are often larger than the maximum integer
value PHP
supports and it therefore I end up with a -ve number and the
revisions
obviously don't match and I get a 412 - conflict.
I then cast the value to a float which is done elsewhere in the
library.
This still resulted in a 412. So I looked at the raw put data from
the
request and compared it to the raw get data I got in the first
place. The
only difference was the by casting to a float _rev was encoded as:
"_rev":123456789
whereas I received it as:
"_rev":"123456789"
By casting as a string just before json encoding I now get a much
happier
201 status code during my testing. Should the server really be
quibbling
over the data type? Not a problem if it does but it was a
difficult one to
track down.
Why are you casting it from a string in the first place? Just treat
it as an
opaque value and return it to the server as sent to you. Besides,
you can't
represent every possible 64 bit integer in a double anyway.
I wasn't my code doing the casting. I am using the CouchDB PHP
classes from the couchprojects php library. It is that code which is
casting to float. I am quite happy to modify the code but it would
be nice to be able to commit my changes upstream so that other can
benefit from them. Anyone have any idea who I can ask to get write
privileges to the svn repo or who I can send the changes to?
that would be me, can you post a patch to the bug tracker on the
couchprojects project? :)
Cheers
Jan

I believe a 412 is a conflict, anyone care to prove me wrong?

Subject: Re: 412 on update
Hi everyone,
I am using the CouchDB PHP library (from
http://couchprojects.googlecode.com/svn/trunk/libraries/php/) to
communicate with the database an I am having some issues
updating a design
document. When I try to save the design document I receive a 412
HTTP status
code. The code below is a simplification of what I am doing but
should
explain what I am trying to do.
$objCouch = new Couch(array("host" => localhost, "port" => 5984));
$objDesignDoc = $objCouch->database($strDB)->get("_design/
ADesignDoc";
$objFunction = new stdClass();
$objFunction->map = "function(doc){if(doc.Type = 'ANode')
{emit(doc.Name,
doc);}}";
$objDesignDoc->views->$strFunc = $objFunction;
$objDesignDoc->save();
echo "Status: " . $objDesignDoc->lastStatusCode . "\n";
What does a 412 status code mean in this context and does anyone
have any
idea what I can do to fix it?
Regards,
Jon
I should have mentioned I am using version 0.8.1 of CouchDB
Thanks,
Jon
