There is a bug and race issue that occurs when a message is selected
while we are in the process of reifying a locally echoed message,
raising the "Selected message id not in MessageList" error.
The code flow to get the exception is as follows:
* A user sends a message to the current narrow we are in.
* Before the new message event is received, we sent a message to
the same message list which renders it with a locally echoed id.
* One of the ways of getting the exception is to already have the
locally sent message selected, before receiving an acknowledgment
from the server.
* Thus the Message List Data's `selected_id` now points to the new
message id. The exception is raised on entering the `was_selected`
if block inside `message_list_view` which tries to re-select the
message.
Updating the `_rerender_message` code for this special case won't fix
the entire bug because, as mentioned above there are other ways of
getting the exception:
Ideally, after all our synchronous work (`echo.process_from_server`)
has completed we would expect the re-order and re-render work of the
`change_message_id` would occur first, due to the timer of the
setTimeout being set to 0.
However as evident from the race condition existing, this isn't always
the case. `change_message_id` function is responsible for 3 things:
updation, re-ordering and re-rendering.
The first one which is responsible for updating the message list's
local cache, occurs synchronously while for the latter two, they both
occur asynchronously.
Before the setTimeout which is responsible for the latter two actions,
is encountered the user might select the message by clicking or more
commonly by scrolling, which causes this message selection event to be
ahead of the setTimeout in the callback queue.
During this time frame, our race condition takes place.
And even though the message id is updated it's Message List is not
in the correct sort order, which leads to `closest_id` !== `id` in
`MessageList_select_id` being true and raising the exception.
Now, we only asynchronously call the re_render function, to guarantee
the data is always correct and UI updates should be done at the end.
Extended by tabbott to comment the setTimeout call.
Fixes#15346.
We change validate_stream_message to check the existence of stream from
the stream name in compose box early and we then pass stream_id or the
obtained sub objects accordingly to other validate functions.
Passing stream_id or sub objects to these functions, enables us to use
stream_id instead of stream name in stream_data.get_subscriber_count.
stream_data.get_stream_post_policy is also removed as we only used it in
validate_stream_message_policy, but we do not need it now as we can get
stream_post_policy directly from sub object obtained by early check of
valid stream name.
This commits add data-stream-id attribute to the compose_invite_users
template. This helps in avoiding the error that occured if user
clicked the link after renaming of stream.
As a result of above changes, the checks for empty and invalid stream
name in compose box are done in warn_if_mentioning_unsubscribed_user
function instead of needs_subscribe_warning function.
Prior to this commit whenever convert was imported from zerver.lib.markdown
it was aliased as markdown_convert for readability.
This commit rename convert function to markdown_convert so that it can be
directly import it without aliasing and without compromising readability.
If a channel has a thousand subscribers this commit results in the count
being displayed with a thousands separator, e.g. with English locale you
get 1,000 instead of 1000.
Since we migrated to `image_upload_widget.hbs`
for upload widget's so we have to access those widget's elements
according to the `image_upload_widget.hbs` new CSS class names.
We need to access delete button element with
`#user-avatar-upload-widget .settings-page-delete-button`
not with old CSS id `#user_avatar_delete_button`.
When we extract common HTML template (`image_upload_widget.hbs` )
for user avatar, realm day/night logo and realm icon widget's
lot of new CSS are created to match image_upload_widget.hbs and
old CSS are preserved in `settings.scss`. This commit removes all
unwanted or unused CSS in `settings.scss`.
Without this change, pyflakes reports this exception:
pyflakes | zerver/worker/queue_processors.py:152:9 local variable 'e' is assigned to but never used
pyflakes | zerver/worker/queue_processors.py:155:81 undefined name 'e'
We use the EMAIL_TIMEOUT django setting to timeout after 15s of trying
to send an email. This will nicely lead to retries in the email_senders
queue, due to the retry_send_email_failures decorator.
smtlib documentation suggests that socket.timeout can be raised as the
result of timing out, so in attempts I'm getting
smtplib.SMTPServerDisconnected. Either way, seems appropriate to add
socket.timeout to the exception that we catch.
Added -d Flag in do-release-upgrade for Bionic to Focal upgrade.
The -d switch is necessary to upgrade from Ubuntu 18.04 LTS
as upgrades have not yet been enabled and will only be enabled
after the first point release of 20.04 LTS.
