[jira] Created: (COUCHDB-99) Broken pagination when browsing
database
Broken pagination when browsing database
----------------------------------------
Key: COUCHDB-99
URL: https://issues.apache.org/jira/browse/COUCHDB-99
Project: CouchDB
Issue Type: Bug
Components: Administration Console
Affects Versions: 0.9
Environment: Debian server, Firefox 3 client
Reporter: Ciaran Gultnieks
Priority: Minor
The pagination is broken when browsing a database. For example, on initially clicking to view the database I see "Showing 1-25 of 7357 rows". Then after clicking the 'Next Page' link, I get "Showing 2-26 of 7357 rows".

-------------------------------------
I'm seeing a possibly related issue: when displaying custom view, only the first 10 rows are shown, with no "next" link, even though there are 31 rows in total. I can view the 31 rows if I set the number of rows per page to 100 instead of 10.

Chris Anderson commented on COUCHDB-99:
---------------------------------------
After some debugging, I'm stumped, but the place to pickup, for anyone who's interested, I think, is
couchdb_updater:btree_by_id_reduce(reduce, FullDocInfos)
If you log the FullDocInfos, you'll see that some of the arguments as they come in, don't match the full_doc_info record. Hence, they are not counted in either column.
It seems that docs that come before the startkey are the ones that don't show up as full_doc_info records in the function, and those which are after the startkey are just fine. I'm not sure why this would be -- might be in the heart of couch_btree:stream_kp_node, but I can't see a reason for this behavior.
Or I could be on the totally wrong track. When this bug is fixed I'll definitely be curious to read the diffs!

[jira] Closed: (COUCHDB-99) Broken pagination when browsing
database
Posted by "Damien Katz (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/COUCHDB-99?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Damien Katz closed COUCHDB-99.
------------------------------
Resolution: Fixed
Assignee: Damien Katz
Fix because skipped reduction values weren't getting assembled before reduction.
Callers of btrees are allowed to use complex objects instead of key/value pair tuples, if they also provide a function to extract the key and the value from the complex object, and another function to re-assemble it. This re-assemble step wasn't happening with certain skipped keys, meaning they couldn't be reduced properly.

---------------------------------------
This is a problem with the _all_docs view not returning the correct offset. Instead of giving the actual offset, _all_docs returns the skip value as the offset. Investigating a fix...
Normal views don't have this problem, just _all_docs.
