- Get rid of DomRange "host objects" (too confusing)
- start to use `r instanceof DomRange` instead of `'dom' in r`
Ported domrange tests; all tests pass
- If the items in an array are strings or numbers, use those as
the id.
- If the items in an array are objects with no '_id' field, use
the index in the array.
- In any case, if the id to be used is already present in this array,
generate a random replacement value and print a warning.
This implies it is not allowed in `observe` either, or in cursors
returned from publish functions, or in cursors used in {{#each}}
Why? observeChanges and DDP publication use the ID as part of the
callback/message, and eliding it completely breaks them. Meteor UI uses
the ID with {{#each}} to properly move nodes around instead of
re-rendering. We could try to allow it for `observe` outside of
{{#each}}, but it would feel somewhat inconsistent.
Previously OplogObserveDriver was only used for selectors which
performed equality checks against scalars. Now that we believe minimongo
to be more robust in the face of more MongoDB edge cases, we use
OplogObserveDriver (if configured) for any selector that minimongo can
compile except those containing $near or $where.
(We still do not use OplogObserveDriver for cursors with skip or limit.)
Now Spacebars syntax errors (as well as html_scanner errors) go through proper error reporting channels rather than throwing exceptions. For simple cases, we are back to showing nice errors like Handlebars did on devel, with context.
Next: Comb the spacebars compiler for errors that are thrown or lack good line numbers. Go through our own list of bad error messages.
This lowers the max websocket frame length from 1GB to 64MB.
Note that due to #1648, this may not immediately affect existing
checkouts of meteor (but will get into all release builds).
Now they are methods on a compiled Matcher rather than doing their own
operator parsing from scratch. This means less work is happening for
each oplog entry, and it also localizes knowledge about selector
parsing.
Previously, $near was only used in the absence of a sort specifier; now,
it's also used as a tie-breaker when there is a sort specifier. (Tested:
this matches MongoDB.)
Big minimongo refactoring. Lays the groundwork for trusting more
selectors in oplog and implementing the '$' option to updates, though
neither are yet implemented.
