Our code hardcoded "rcstart" in both
string value and C++ class member
name. This change is really a breaking one to us.
Could you tell me when this is released to *wiki?
The change is coming with 1.21wmf12. Due to a major bug in that release, I
don't know when it will be deployed anywhere besides test2wiki.
Can I understand that once the bug is fixed on test2wiki, it will be
deployed to *wiki and other media wiki sites immediately? or is it released
on a regular base (e.g. 2 weeks later? - in this case, it means we have at
least 2 weeks to fix our code)
And when deploying the new release, is it done to all sites at once or
one-by-one in a release window? (if the release proces last for a while,
e.g. 1-2 days, our change need to handle both new style and old style,
Note that the "rcstart" parameter is not going away. It's just that the
query-continue will start using "rccontinue" as a key rather than
"rcstart". For the moment, you can compare  and  to see the
Here is more background of our broken:
(sadly) our code DO look into both the value of "rcstart" (e.g.
"2013-03-23T02:53:28Z") and the attribute name itself ("rcstart"). Now
understand we should not do that.
But it is not easy for us to have a quick fix this time, the parsing of XML
is done by another library which is much older, and hard to change.
To have a complete fix (I mean respect the spec, not looking into the
attribute names or values), we need 1-2 weeks at least. So I'd prefer a
quick fix if something still works.
It looks to me I can still sends out rcstart by strip the "|?????" from
Could you confirm this is what I can expect with the release of 1.21wmf12?
