This is a limitation inherited from Apache CouchDB, maybe we can get rid of it post 2.0. <br/> <br/> This can be little confusing for the users as views appear to be independent of each other. <br/> <br/> See <a href="http://www.couchbase.com/issues/browse/CBSE-238">http://www.couchbase.com/issues/browse/CBSE-238</a> for an example case.

[RN 2.0.1] Map function failure in a view for a document causes it to be unavailable for all other views in the design document

Bug Blocker Closed Fixed Public Karen Zeller Deepkaran Salooja 2.0-release-notes customer Fri, 12 Oct 2012 06:11:47 -0500 Wed, 6 Mar 2013 17:27:14 -0600 Wed, 6 Mar 2013 17:27:08 -0600 2.0 2.0.1 documentation 1 6 Dipti,<br/> <br/> should we assign this to MC for documentation ? I consider this a bug. Filipe, can you provide feedback on how this can be fixed? <br/> <br/> In this case, why did the view fail in the first case? This is not a trivial change to do, and I think it&#39;s a bit late to do it. <br/> <br/> Not sure if I understand your question about why it failed. <br/> It&#39;s a map function run time error for a particular document, we log/report the error and move on. And, results for other views in the same design document for that particular document are not considered. <br/> CouchDB has had this behaviour for years, I don&#39;t remember it being otherwise. It&#39;s a bit like a compiler, if one source file fails, the program can&#39;t be build. The solution: fix your map functions. The solution cannot be fix your map functions. Its very non-intuitive behavior for a database and makes development tough. <br/> <br/> Will need to fix in 2.0.1. where is the mapreduce_errors file located? For development builds at least, it&#39;s in the same directory as all other log files. bug-scrub: keeping in 2.0.1 for now, as two customers have reported running into this -- adoption issue. Moving to 2.0.2, it&#39;s out of scope for 2.0.1. <br/> <br/> Filipe, feel free to move back if you don&#39;t agree. Need to move back as its a customer issue and a community issue hit by several folks. As discussed in the bug scrub on Friday, this is a blocker for 2.0.1. <br/> If we cannot make it in this coming week, we can revisit. per bug-scrub: Filipe: I think you have made progress on this. Can you please update the bug re:fix? We are trying to lock-down functional bugs by Friday. <a href="http://review.couchbase.org/#/c/24205/">http://review.couchbase.org/#/c/24205/</a> <br/> <a href="http://review.couchbase.org/#/c/24206/">http://review.couchbase.org/#/c/24206/</a> Thanks :-) merged Integrated in github-couchdb-preview #558 (See [<a href="http://qa.hq.northscale.net/job/github-couchdb-preview/558/">http://qa.hq.northscale.net/job/github-couchdb-preview/558/</a>])<br/> &nbsp;&nbsp;&nbsp;&nbsp;<a href="http://www.couchbase.com/issues/browse/MB-6895" title="[RN 2.0.1] Map function failure in a view for a document causes it to be unavailable for all other views in the design document "><strike>MB-6895</strike></a> Better map function error isolation (Revision cb32250806b28e9df6892f0ce652a9cb51949738)<br/> <br/> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Result = SUCCESS<br/> Filipe David Borba Manana : <br/> Files : <br/> * src/couchdb/couch_view_updater.erl<br/> * src/mapreduce/win32/mapreduce.vcxproj.tpl.in<br/> * src/mapreduce/mapreduce.cc<br/> * src/couch_set_view/test/12-errors.t<br/> * src/mapreduce/mapreduce.h<br/> * src/mapreduce/Makefile.am<br/> * src/mapreduce/test/01-map.t<br/> * src/mapreduce/mapreduce_nif.cc<br/> * src/mapreduce/nif_stl_allocator.h<br/> * src/couch_set_view/src/couch_set_view_updater.erl<br/> For dev-subset queries, with one view having error in mapfuction is causing other views not to give results.
