Since channels_redis does not support dedicated read-redis instances, the
autoupdate message may be received before the data was replicated. All workers
read the autoupdate message from the write host, so there is a race between
getting this message and a finished replication. For large payloads, the
replication is slower in the most cases (even more in a distributed setup, where
the master and replica are on different nodes). The easy way is to wait for
replication. But there is one difficulty: The number of replicas has to be
known. There is a new settings-variable "AMOUNT_REPLICAS" which defaults to 1.
It needs to be set correctly! If it is too high, every autoupdate will be
delayed by 1 seconds because of a timeout witing for non-existent replicas. If
it is too low, some autoupdates may be wrong (and not detectable by the client!)
becuase of reading from non-synchronised relicas.
The other possibility is to fork channel_redis and add the feature of a
read-only redis. This ould help, because on a single redis instance all commands
are ordered: First, the data is synced, then the autoupdate message. Attention:
This means, if redis-replicas are scaled up, one must make sure to read from the
same instance. I think this is not possible in the way how dockers overlay
networks work. The only way would be to open one connection and reuse the
connection from channels_redis in OpenSlides. This would mean a heavy
integration of channels_redis (meaning including the source code in our repo).
For the first fix, this one is easy and should work.
adds a "is present" toggle to the user menu
Refactor user menu into own component
Add a config variable to determine if the user is allowed
to set themselve as present
- Remove "assignments.can_manage_polls" permission
- Let the client handle some user errors
- Add a send button to manually submit polls
- Show a hint that the user already submitted a vote
- will not (and should not) work for non-nominal voting
- submitting a vote cannot be changed anymore
- user will have to confirm sending
- enable deselecting YNA-votings
- nomainal voting will behace the same as non nominal voting
- submitting empty votes should be possible
Perhaps server side adjustments might still be required
- repaired the PDF Service for ballots
- fixed some permission errors
- analog voting has no "started" option anymore
- more-link as button
- named voting has a progress bar
- Shows the poll type for eVoting
- Moves and declutters meta info
- Enhance the grid and the layout in detail view
- declutter and enhance the dot-menus
- some other layout changes
- remove breadcrumbs in assignment detail
- other cleanups refinements
- Voting in Assignment over instead of forms
(requires more server changes)
- cleaned up a lot of code
- removed required majotiry from forms
- renamed verbose "Majority method" to "Required majority"
- poll-progress-bar only counts present user
- enhanced motion poll tile chart layout
- removed PercentBase.Votes
- added pollPercentBase pipe
- Show the voting percent next to chart in motion detail
- change the head bar to "Voting is open"
and "Ballot is open"
- merged the voting configs to their corresponding config-categories
- re-add ballot paper configs
- Add "more" button to motion polls
- Adjusted the motion results table
- Hide entries without information
- Show icons for Y N A
- Show percentage next to Y N A
For Motion poll:
- Overworked how motion poll chart displays the legend
- Added the vote counter to the motion detail
- Added a progress bar to the vote counter
- Fixed some perm errors with the chart
- Show a "Singe Votes" link as button for published named polls
- Replace the edit-button with a dot-menu
- Having project, Edit, PDF and Delete
For Motion Poll detail:
- enhance search panel
- Remove the breadcrumbs
- Remove the vote counter
- Enhanced the single-vote grid, table and filter bar
- Enhance how the poll state enum was checkend
For the Motion Poll Create/Update Form:
- Remove the selection of poll-methode (whenever possible)
- only show "publish imediately" during creation
Renamed the option
"Show submitters and recommendation in table of contents"
to
"Show submitters and recommendation/state in table of contents"
If the option is selected, the PDF-TOC for motions will print
the name of the current state (if final) rather than the
current recomendation
Adds various changes for a more complete 3.1 release
- cleaner "current slide" description in projector detail (grid with ellipsis)
- show the previously projected slides as ordered lists under the accordion
- fix a bug where everyone could access the projection manage view (although it was unfunctional without the correct permissions)
- assignment list now uses the correct ellipsis
- fixes a bug where the lable "list of speakers" was not translated on the projector slide
- Show a lock on the "list of speaker"-slide if it has been closed
- enable dialog tests that have previously been disabled
It is not given, that null values are sorted last in the `order_by("-end_time")`
statement. This did not happens in the tests, but in a productive environment.
See https://docs.djangoproject.com/en/2.2/ref/models/querysets/#order-by for a
`.asc()`/`.desc()` option `nulls_last`. I choose another approach to just
exclude these values.
