CouchDB crashes when GETting view from a legacy DB
--------------------------------------------------

                 Key: COUCHDB-179
                 URL: https://issues.apache.org/jira/browse/COUCHDB-179
             Project: CouchDB
          Issue Type: Bug
          Components: Database Core
    Affects Versions: 0.9
         Environment: uname -a
Linux dyc-ucbdesk 2.6.24-22-generic #1 SMP Mon Nov 24 19:35:06 UTC 2008 x86_64 GNU/Linux
erl
Erlang (BEAM) emulator version 5.6.4 [source] [64-bit] [smp:2] [async-threads:0] [hipe] [kernel-poll:true]
CouchDB
Apache CouchDB 0.9.0a727978-incubating (LogLevel=info) is starting.
            Reporter: Ulises Cervino Beresi


Working with a legacy DB (which works just fine with version r725308) makes beam.smp use up
all the memory until it is killed by the kernel.

Log:
couchdb@dyc-ucbdesk:/opt/couchdb-trunk-dk-fix$ ./bin/couchdb -i
Erlang (BEAM) emulator version 5.6.4 [source] [64-bit] [smp:2] [async-threads:0] [hipe] [kernel-poll:true]

[info] [<0.67.0>] Starting process for: action
Apache CouchDB has started. Time to relax.

1> SyntaxError: syntax error

It looks like it tries to recompute the view on GETting it.

View

index/by_timestamp
map:
  function(doc) {
    emit(doc.timestamp, null);
  }

DB size is .5G, avg doc size is 3M, doc structure:

{
 'text': 'long string ... really long',
 'id': 'my IDS',
 'timestamp': 'date' // e.g. 2008-12-13T03:51:57.732618
}

default.ini and local.ini for latest couchdb are not changed at all except for the DB dir
location.
