- Correctly position certain elements
- Reduce flicker/things moving around in various cases
- Force dropdown to open in case there is a message to display
Rationale: "wait" methods are used for login/logout, which tend to make drastic
changes that should take effect atomically rather than streamy. (Without this,
logging out with accounts-ui saw the username disappear before the buttons
switched from "sign out" to "sign in", eg in single-button mode. Now it goes
directly from "signed in with username visible" to "signed out".)
There is no longer any explicit time-based throttling of Mongo poll calls,
though we do prevent multiple instances of polling to be scheduled at once. If
this appears to be a problem, we can reintroduce throttling.
Note: this can lead to a hang if you start observing a cursor during a callback
from an identical cursor's observation. This doesn't seem to be a very realistic
use case though.
Separate the "description" of the cursor from the actual wrapped Mongo
cursor.
Collection.find() no longer runs a Mongo query: you have to actually call a
function like fetch, count, or observe on the cursor to run the
query. (Specifically, this lets us skip a useless query when a publish function
returns the result of a find().) This implies that errors that used to be
reported at find() time are now reported later.
Also, allow objects other than Mongo cursors returned from publish functions to
define their own _publishCursor functions (this is not documented or officially
supported). The _publishCursor code is moved from the livedata package to
mongo-livedata.
- Data streamed from the server is quiesced on a per-object basis, not a global
basis. We track which documents a method stubs modifies, and create individual
snapshots ("server documents") of those documents rather than whole-Collection
snapshots. Data writes from the server to documents not modified by stubs are
applied immediately to the local cache; other writes are applied to the
"server document" snapshots. Server documents are flushed to the local cache
when all method stubs that wrote to the document have sent their "data write"
message. (We still do "full database" quiescence after a reconnect.)
- Instead of calling method callbacks as soon as the result is received, we wait
until all data that precedes their "data done" message is flushed to the local
cache. This way, method callbacks can see all of their results locally. (This
applies to Collection mutator callbacks as well.) If this delay is
unacceptable, you can also specify the onResultReceived option to
Meteor.apply; this callback is given the method result as soon as it comes in,
and there's no guarantee that the local cache is up to date.
(This is a client-only change: server-side callbacks do not block on the
write fence.)
- Methods invoked with the "wait" option to Meteor.apply now wait until all
preceding methods are fully finished to be *sent*, not just to call their
callbacks. ie, previous calls block the "wait" method in the same way that
"wait" methods block subsequent calls.
- Remove Meteor.userLoaded and {{currentUserLoaded}}.
Meteor.userId() is now set only at the point where Meteor.user() is fully
loaded.
Current user data is published via an unnamed subscription, not via
"meteor.currentUser".
Replace them with Meteor.loggingIn() and {{loggingIn}}, which become true
as soon as the login method is sent (instead of only once it succeeds).
In accounts-ui, move the spinny into the dropdown, because it now shows up
before error messages would.
- Previously, if we received the "result" message from a method but no "data"
message, and then disconnected and reconnected, quiescence would be
permanently blocked. Now, not only do we allow the app to continue working,
but we even guarantee that the method's callback will be called at the
"reconnect quiescence" point.
- Remove reset function from the Store API (the interface between
_LivedataConnection and Collection), and add a boolean "reset" argument to
beginUpdate instead.
Add saveOriginals/retrieveOriginals functions to the Store API (pass-through
to minimongo implementation).
Allow "replace" messages to be passed to the Store API's update function
(in addition to set/unset).
Allow Store API implementations (eg tinytest_client) to not specify all
functions.
- Server-side tinytest results now stream into the result page instead of
appearing all at once at the end.
- Rename fields and methods of Meteor._LivedataConnection as camelCase, and
prepend all internal fields with _.
- Different Meteor._LivedataConnection objects now have separate
_userIdListeners _ContextSets.
- Remove snapshot/restore functionality from Minimongo collections. (Individual
queries still have result snapshots.) The "server documents" in
Meteor._LivedataConnection serve the equivalent purpose.
- Meteor.loginWithToken's callback is now a "call with error on error, call
with no args on success" callback like the other login callbacks.
- The test-only Meteor._LivedataConnection.onQuiesce function is removed.
Every single use of it is now supported by normal method callbacks.
This will eventually be used to replace snapshot/restore. snapshot/restore are
used to implement full-database quiescence; saveOriginal/retrieveOriginal will
be used to implement per-object quiescence.
Also, throw on duplicate-ID insert.
This reverts commit 0092a560f2.
The goal for _WriteFence is that it be specific to the concept of declaring when
writes are done (and one day may be a networked message bus), not that it be a
generic "call this method after these methods" helper.
Meteor's sass package wraps the "sass" NPM module, which implements a version of
the Sass language much older than the .sass described at sass-lang.com (and
doesn't implement the current recommended .scss language at all). It also has
poor error handling, so it mostly just ends up confusing users.
The module is unmaintained, and its author now uses stylus/nib (which Meteor
supports: see the stylus package).
If many users want Sass support, we could add this back in wrapping the
"node-sass" package instead (which supports a more recent version of the Sass
language), but for now, just remove it. Meteor still supports Stylus and Less
out of the box.
Fixes#143.
