It seems the Ubuntu base image we use now has a new enough VirtualBox
Guest Additions to trigger the ETXTBSY bug even when it’s not upgraded
by the vagrant-vbguest plugin. Provide and document a way to
downgrade it.

There are file sharing issues with the macOS 10.15.6 and
vagrant. var/remote_cache_prefix was an empty file when using
VirtualBox and Docker on macOS.
Using parallels as a provider for vagrant fixes the issue.
Use --watch-poll which makes webpack to recompile
automatically on file changes, since inotify is not
working here too.
Instructions were added by doing the setup on Ubuntu 18.04 WSL 2.
While the setup should be similar for other distributions supported by
our `./tools/provision` script inside WSL, it has not been tested.
Polished by tabbott.
This returns us to a consistent logging format regardless of whether
the request is authenticated.
We also update some log examples in docs to be consistent with the new
style.
Zulip has had a small use of WebSockets (specifically, for the code
path of sending messages, via the webapp only) since ~2013. We
originally added this use of WebSockets in the hope that the latency
benefits of doing so would allow us to avoid implementing a markdown
local echo; they were not. Further, HTTP/2 may have eliminated the
latency difference we hoped to exploit by using WebSockets in any
case.
While we’d originally imagined using WebSockets for other endpoints,
there was never a good justification for moving more components to the
WebSockets system.
This WebSockets code path had a lot of downsides/complexity,
including:
* The messy hack involving constructing an emulated request object to
hook into doing Django requests.
* The `message_senders` queue processor system, which increases RAM
needs and must be provisioned independently from the rest of the
server).
* A duplicate check_send_receive_time Nagios test specific to
WebSockets.
* The requirement for users to have their firewalls/NATs allow
WebSocket connections, and a setting to disable them for networks
where WebSockets don’t work.
* Dependencies on the SockJS family of libraries, which has at times
been poorly maintained, and periodically throws random JavaScript
exceptions in our production environments without a deep enough
traceback to effectively investigate.
* A total of about 1600 lines of our code related to the feature.
* Increased load on the Tornado system, especially around a Zulip
server restart, and especially for large installations like
zulipchat.com, resulting in extra delay before messages can be sent
again.
As detailed in
https://github.com/zulip/zulip/pull/12862#issuecomment-536152397, it
appears that removing WebSockets moderately increases the time it
takes for the `send_message` API query to return from the server, but
does not significantly change the time between when a message is sent
and when it is received by clients. We don’t understand the reason
for that change (suggesting the possibility of a measurement error),
and even if it is a real change, we consider that potential small
latency regression to be acceptable.
If we later want WebSockets, we’ll likely want to just use Django
Channels.

- Updated 260+ links from ".html" to ".md" to reduce the number of issues
reported about hyperlinks not working when viewing docs on Github.
- Removed temporary workaround that suppressed all warnings reported
by sphinx build for every link ending in ".html".
Details:
The recent upgrade to recommonmark==0.5.0 supports auto-converting
".md" links to ".html" so that the resulting HTML output is correct.
Notice that links pointing to a heading i.e. "../filename.html#heading",
were not updated because recommonmark does not auto-convert them.
These links do not generate build warnings and do not cause any issues.
However, there are about ~100 such links that might still get misreported
as broken links. This will be a follow-up issue.
Background:
docs: pip upgrade recommonmark and CommonMark #13013
docs: Allow .md links between doc pages #11719Fixes#11087.
Add a specific command to restart Vagrant to adopt the new
configuration.
(When naïvely using only `vagrant halt` + `vagrant up --provision`,
external devices remained unable to connect; per `netstat -nltp`, the
host IP of forwarded ports remained `127.0.0.1`.)
This plugin automatically updates the VirtualBox Guest Additions in
the guest, which makes shared folders work more reliably.

Many Linux distros like Debian Buster, Fedora 29, etc. have a policy
where any services installed are disabled by default. So we should let
the developer know that they should explicitly enable and start the
Docker daemon.
Also, we should be verbose on how to do vagrant up using Docker as a
provider specifically (and similar for Virtualbox).
This also means the default dev environment is now based on Ubuntu
18.04 (bionic), part of our overall effort to migrate off Ubuntu
Trusty.

Two variables were declared and assigned the respective values of the
default settings for the system. If the keyword is used in the
~/.zulip-vagrant-config file, the value is assigned to the variable.
There is no straightforward way to customize the virtual machine's
number of cpus or memory, this commit addresses that fact.
Sphinx/ReadTheDocs supports automatically translating links written as
to `.md` files to point to the corresponding `.html` files, so this
migration does not change the resulting HTML output in ReadTheDocs.
But it does fix apparent broken links on GitHub.
This doesn't prevent people from reading the documentation on GitHub
(so doesn't mitigate the fact that some rtd-specific syntax does not
render properly on GH), but it will prevent us from getting erroneous
issues reported about the hyperlinks not working.
Fixes: #11087.
Add the recommendation in docs for not using GitHub Desktop client for
zulip code as it has a bug of keeping the symlinks disabled and ignoring
any configuration done to re-enable it resulting into failure to identify
the received symlinks leading to failing test cases in the zulip development
environment.
The history of this was that there was a period where half of Vagrant
releases were broken (for everyone, e.g. downloading a base container
didn't work). It seems Vagrant has cleaned up their act at this point.
We really just want 2.0.x, not a specific version, and the direct
links we had are now quite old.
Thanks to Jonathon Hinchley for reporting this.
Fixes#11836.
help.github.com seems to have a bug where HEAD on a redirected page
returns 404. This causes tools/test-documentation to fail. Fix it by
skipping the redirects.

Older versions of virtual box were giving installation error in new
MacOS Mojave. While originally we considered changing the docs to
point to the current version 5.2.20, it seems better to just not pin a
version.
Significantly tweaked by tabbott.
On OSX, the user id and group id don't match. So while the previous
code was always wrong, it produced incorrect output there. We can fix
this by replacing `whoami` with `id -g` for finding the current user's
group ID.
This didn't really make much sense - it presented a quickstart summary
of the instructions as an item in the list of differences from the
Ubuntu case, plus that quickstart only incorporated one of the two
actual differences so it didn't work anyway. Given the networking
stuff, an actual quickstart isn't in the cards, so just cut that.
Also fix some small things while we're here.
