flags, and hook them up to the WT_CONNECTION->is_new method.
Add a global structure (WT_PROCESS), which includes a mutex and
maintains a linked list of the WT_CONNECTION structures in the process.
Change the underlying "file exists" function to correctly return errors,
rather than including errors in "file doesn't exist" returns.
The only place we're using the string output separator is in the debug
code, remove it from the "global" structure, and make it static in the
Btree debug file.
Move the close of the logging file handle into WT_CONNECTION destroy,
instead of doing in connection close. This isn't right, but right now
we don't have a good dividing line between what code in
connection-open/connection-close, connection-init/connection-destroy,
and then there's a bunch of initialization in wiredtiger_open too.
Delete the home/mode arguments from __wt_connection_open, they were
never used and I think they are never going to be used, at this point.
Minor re-working of the mutex functions so they handle NULL WT_SESSION
handles correctly.
Add cursor->search function for Btree tables, cursor->search_near has
to do quite a bit more work if there's no exact match, we don't want
to slow down normal lookup.
Replace WT_CURSOR_BTREE->match with WT_CURSOR_BTREE->compare which
matches the semantics of the exact parameter to cursor->search_near,
that is, -1 if it's a smaller key in the tree, 0 for an exact match,
and 1 if it's a larger key in the tree.
The cursor->search_near function has to return a key if the match is
not exact: change __wt_return_value() to optionally return a key, and
rename it to __wt_kv_return().
Split read statistics into read and read-near.
Move set of WT_CURSOR_BTREE->flags(WT_CBT_SEARCH_SET) down into the
search routines.
Change __cursor_deleted() to be a boolean, not returning an error value,
we don't necessarily return error on deleted records.
The search routines don't return WT_RESTART, that only happens if the
tree is modified: remove restart loops from search calls, add restart
loops to modify calls.
