The contents in the database are unchanged across the PostgreSQL
restart; as such, there is no reason to invalidate the caches.
This step was inherited from the general operating system upgrade
documentation. When Python versions change, such as during OS
upgrades, we must ensure that memcached is cleared. However, the
`do-release-upgrade` process uninstalled and upgraded to a new
memcached, as well as likely restarted the system; a separate step for
OS upgrades to restart memcached is thus unnecessary.
pg_upgradecluster has two possibilities for `--method`: `dump`, and
`upgrade`. The former is the default, and does a `pg_dump` of all of
the databases in the old cluster and feeds them into the new cluster.
This is a sure-fire way of getting the same information in both
databases, but may be extremely slow on large databases, and is
guaranteed to fail on servers whose databases take up >50% of their
disk.
The `--method=upgrade` method, by contrast, uses pg_upgrade to copy
the raw database data file over to the new cluster, and then fiddles
with their internal structure as needed by the upgrade to let them be
correct for the new version[1]. This is slightly faster than the
dump/load method, since it skips the serialization step, but still
requires that there be enough space on disk for both old and new
versions at once. `pg_upgrade` is currently supported for all
versions of PostgreSQL from 8.4 to 12.
Using `pg_upgrade` incurs slightly more risk, but since the it is
widely used by now, using it in the relatively-controlled Zulip server
environment is reasonable. The expected worst failure is failure to
upgrade, not corruption or data loss.
Additionally passing `--link` uses hardlinks to link the data files
into both the old and new directories simultaneously. This resolve
both the runtime of the operation, as well as the disk space usage.
The only potential downside to this is that as soon as writes have
occurred on the upgraded cluster, the old cluster can no longer be
started. Since this tooling intends to remove the old cluster
immediately after the upgrade completes successfully, this is not a
significant drawback.
Switch to using `--method=upgrade --link`. This technique spits out
two shell scripts which are expected to be run after completion of the
upgrade; one re-analyzes the statistics, the other does an `rm -rf` of
the data where it is still hardlinked in the old cluster. Extract the
location of these scripts from parsing the `pg_upgradecluster` output;
since the path is not static, we must rely on it being relatively easy
to parse. The risk of the path changing is lower, and has more
obvious failure modes, than inserting the current contents of these
upgrade steps into the overall `upgrade-postgres`.

We have logic in place to update the ui for re-sending messages
on recieving the acknowledgement from the server on that API call.
However, if the acknowledgement is recieved through the get events
request before the `on_success` of `resend_message`, the message
gets re-rendered allowing the failed message actions to be clickable.
Now, we update the ".message_failed" ui for both cases. This helps
in preventing the "Trying to get local_id from row that has reified
message id" exception.
Fixes#15351.
Previously, we rendered the twitter previews outside of a
spoiler block at the end of the message. The commit series
ending with this commit fixes that by inlining twitter
previews instead of appending them all at the end. As a
consequence of the inlining, we have fixed the issue here.
This commit just adds a test to assert that.
Fixes#15518.
This is similar to our behavior with image previews, and helps
reduce clutter in the final rendered html.
We add the string 'Tweet: ' to our existing tests so those tests
remain the same.
This commit makes our handling of twitter previews consistent with
how we handle our inline images so that tweets render next to the
paragraph that links to the tweet.
We decouple the logic of insertion rules for inline links from
image preview logic. Now, we can use this same logic for other
kinds of link previews as well.
fadeTo is not a good method to hide elements since it sets
opacity to 0 in which the element still can consume space and
be clickable. We set it's display to None using fadeOut method.
Also, allow this method to be called via ui_report.error.
The one complexity is that hosts_fullstack are treated differently, as
they are not currently found in the manual `hosts` list, and as such
do not get munin monitoring.
check_memcached does not support memcached authentication even in its
latest release (it’s in a TODO item comment, and that’s it), and was
never particularly useful.
Although mktemp is deprecated due to security issues, this is not a
security issue.
The security problems with mktemp happen when you open the resulting
filename (without O_EXCL) in a publicly writable directory, because
then someone else might have predicted the filename and created or
symlinked or hardlinked something there between the mktemp and the
open, causing you to write to a file you didn’t expect.
Here we don’t open the resulting filename, we symlink to it. symlink
will refuse to clobber an existing file, and we handle the error that
arises from this case. This is the normal way to atomically create a
symlink.
We should still replace mktemp because it’s deprecated, but we can’t
replace it with a function that creates the temporary file. Instead
we build a random filename ourselves.

Previously .recipient_row_date was positioned absolutely, allowing it to
overlap with the topic name on narrow screens. This can be solved by
using flexbox. To implement the empty space between the bar controls and
the date on wider screens we move the date outside of the bar controls
(which also makes more sense semantically since the date isn't a
control).
Fixes#15501.
The stream notification settings checkboxes were not checked
even when the notifications were turned on for the stream.
This was happening because we were passing stream name to
receives_notifications instead of stream id.
This commit fixes the bug by passing stream id to
receives_notifications. This change should have been done
in f3604fb while refactoring receives_notifications to use
stream id instead of name.
As a consequence of commit 1113589b9d the backspace key and some other
keys did not respond if the search yielded no results.
This change fixes that bug.
We also remove the post_process_data option.
The sanity check is just overkill at this point,
since the mechanism to find streams is very
direct due to a recent commit.
Before this change we would only export streams
that had actual subscribers, which is usually
harmless, but it was mostly a relic of a one
time migration that we did when we were cleaning
up some dirty data in some of our very early
databases (circa 2016).
Now we work down the table hierarchy in a
more natural way:
- get Streams in Realm
- get Recipients matching above Streams
- get Subscriptions matching above Recipients
Note that for per-user exports, I kept the
same logic (users -> subscriptions -> recipients ->
streams) we had before.
One subtle detail here is that we make our
final Config blocks--which build the final
version of Recipient/Subscription--now hang
off of realm_config.
Fixes#15146.
This fixes the bug of extra topics not being rendered on scrolling.
list_render uses `max-height` to determine which container is being
scrolled upon. Set the `max-height` on the scrolling container of
recent topics to help list_render identify it.
This is useful for the emoji-picker where holding down shift lets you
select multiple emojis. Otherwise when selecting multiple emojis with
the keyboard shortcuts you would need to release shift everytime you
wanted to navigate with the arrow keys.
Previously clicking on an existing message reaction (outside of the
emoji picker) while having the emoji picker open, removed the reaction
without updating the highlighting of the reacted emoji in the emoji
picker.
The emoji picker already is already closed when clicking outside.
The message reaction click handler however previously stopped the event
propagation, leaving the picker open, allowing the inconsistency.
Since we already run this on every push we don't need to run it as a
cron job every week for no reason. While we are touching this code
block, we convert it to on: [push, pull_request] since the previous
format felt weird. It was only written that way because we had the
cron job declared there.
