Yashashvi Dave 649fccde6b zerver/lib/events.py: Fix custom field values not updated in apply_events.
Custom profile field value are stored in different structure compare to
other profile fields in events, so generic way to update fields wasn't
updating custom profile fields in `apply_event` function.

Fix this by adding check for custom fields in `apply_event`.

This also adds the appropriate test_events test to verify this code path.

Fixes part of #9875.

Shubham Dhama 49deb5acd3 bugdown: Move global variables to arguments.py.
This has two advantages;

* We can split bugdown/__init__.py into several modules, and each
  module can access these arguments by importing these

* We get rid of the super-ugly `global db_data` construct, replacing
  it with a only slightly ugly monkey-ish patching of the
  `zerver.lib.bugdown.arguments` module, which is at least
  considerably more clear on reading as to what it's purpose is.

Armaan Ahluwalia 54d3d8e8b3 webpack: Transition app.js to be compiled by webpack.
This commit moves all files previously under the 'app' bundle in
the Django pipeline to being compiled by webpack under the 'app'
entry point. In the process, it moves assets under the app entry
to a file called app.js that consumes all relevant css and js files.

This commit also edits the webpack config to be able to expose certain
variables for third party libraries that are currently required by
some modules. This is bad coding form and should be refactored to
requiring whatever dependencies a module may have; we're just
deferring that to the future to simplify the series of transitions we
need to do here. The variable exposure is done using expose-loader in
webpack.

The app/index.html template is edited to override the newly introduced
'commonjs' block in the base template. This is done as a temporary
measure so as not to disrupt other pages on the app during the transition.

It also fixes the value of the 'this' context that was being inferred
as window by third party libraries. This is done using imports-loader
in the webpack config.  This is also messy and probably isn't how we
want things to work long term.

Tim Abbott 5a99118b3e auth: Restore a minimal SocialAuthMixin.
We need to do a small monkey-patching of python-social-auth to ensure
that it doesn't 500 the request when a user does something funny in
their browser (e.g. using the back button in the auth flow) that is
fundamentally a user error, not a server error.

This was present in the pre-rewrite version of our Social auth
codebase, without clear documentation; I've fixed the explanation
part here.

It's perhaps worth investigating with the core social auth team
whether there's a better way to do this.

Tim Abbott c9b0c0add4 github: Refactor email extraction to use the full emails data set.
It's possible to make GitHub social authentication support letting the
user pick which of their verified email addresses to pick, using the
python-social-auth pipeline feature.  We need to add an additional
screen to let the user pick, so we're not adding support for that now,
but this at least migrates this to use the data set of all emails that
have been verified as associated with the user's GitHub account (and
we just assume the user wants their primary email).

This also fixes the inability for very old GitHub accounts (where the
`email` field in the details might be a string the user wanted on
their GitHub profile page) to using GitHub auth to login.

Fixes #9127.

Anders Kaseorg d8ba378050 test_slack_importer: Remove backslashes wrongly copied from JSON data
https://github.com/houstondatavis/slack-export/blob/master/users.json

JSON or JavaScript decodes "\/" to / (and some encoders always write
"\/" to avoid accidentally creating a </script> tag), while Python
assumes "\/" is a typo for "\\/" and decodes it to \/.

Anders Kaseorg 037f696d26 Enable pycodestyle W605 (invalid escape sequence).
The only changes visible at the AST level, checked using
https://github.com/asottile/astpretty, are

zerver/lib/test_fixtures.py:
'\x1b\\[(1|0)m' ↦ '\\x1b\\[(1|0)m'
'\\[[X| ]\\] (\\d+_.+)\n' ↦ '\\[[X| ]\\] (\\d+_.+)\\n'

which is fine because re treats '\\x1b' and '\\n' the same way as
'\x1b' and '\n'.

Yago González d151f4a234 messages: Allow fetching unedited messages' history.
When GETting an unedited message's edit history, the server wasn't able

Rhea Parekh 6b7b6b38ad slack import: Write messages batch-wise.
Messages can be bulky, and storing them in a single

Rhea Parekh af20ef4789 slack import: Save messages within convert_slack_workspace_messages.
Previously, the messages where being stored in a output file from
outside the function 'convert_slack_workspace_messages', but
now we store it from the inside the mentioned function.
This will help in processing and saving the messages batch-wise
so as to avoid a memory error.

Reactions are returned separately from 'convert_slack_workspace_messages'
rather than 'message_json'.

Also updated test for 'convert_slack_workspace_messages' and an additional
test for reactions is added.

Tim Abbott 7d250cb2f9 attachment: Fix handling of stream history.
This fixes two issues:

* Our guest users feature gave guest users access to public stream
  attachments even if they couldn't access the public stream.

* After a user joins a private stream with our new shared history
  feature, they couldn't see images uploaded before they joined.

The tests need to check for a few types of issues:
* The actual access control permissions.
* How many database queries are used in the various
  cases for that second model, especially with multiple messages
  referencing an attachment.  This function gets called a lot, and we
  want to keep it fast.

Tim Abbott ec90322e5d bots: Fix behavior for bots mentioned in PMs.
We've for a long time had the behavior that a bot mentioned in a
stream message receives the notification, regardless of whether the
bot was actually subscribed to the stream.

Apparently, this behavior also triggered if you mentioned a bot in a
private message (i.e. the bot would be delievered the private message
and would probably respond unhelpfully in a new group private message
thread with the PMs original recipients plus the bot).

The fix for this bug is simple: To exclude this feature for private
messages.

Steve Howell bfc13ecea4 submessages: Just send content for submessage events.
For some reason in my original version I was sending both
content and data to the client for submessage events,
where data === JSON.parse(content).  There's no reason
to not just let the client parse it, since the client
already does it for data that comes on the original
message, and since we might eventually have non-JSON
payloads.

The server still continues to validate that the payload
is JSON, and the client will blueslip if the server
regressses and sends bad JSON for some reason.

Tim Abbott 91ec0aba09 auth: Improve interactions between LDAPAuthBackend and EmailAuthBackend.
Previously, if you had LDAPAuthBackend enabled, we basically blocked
any other auth backends from working at all, by requiring the user's
login flow include verifying the user's LDAP password.

We still want to enforce that in the case that the account email
matches LDAP_APPEND_DOMAIN, but there's a reasonable corner case:
Having effectively guest users from outside the LDAP domain.

We don't want to allow creating a Zulip-level password for a user
inside the LDAP domain, so we still verify the LDAP password in that
flow, but if the email is allowed to register (due to invite or
whatever) but is outside the LDAP domain for the organization, we
allow it to create an account and set a password.

For the moment, this solution only covers EmailAuthBackend.  It's
likely that just extending the list of other backends we check for in
the new conditional on `email_auth_backend` would be correct, but we
haven't done any testing for those cases, and with auth code paths,
it's better to disallow than allow untested code paths.

Fixes #9422.

Tim Abbott 3842404cc0 ldap: Don't allow password reset for users in LDAP domain.
This is the analog of the last commit, for the password reset flow.
For these users, they should be managing/changing their password in
the LDAP server.

The error message for users doing the wrong thing here is nonexistent
isn't great, but it should be a rare situation.

Tim Abbott 8119670da1 user_settings: Prevent LDAP users from setting a Zulip password.
Previously, if both EmailAuthBackend and LDAPAuthBackend were enabled,
LDAP users could set a password using EmailAuthBackend and continue to
use that password, even if their LDAP account was later deactivated.

That configuration wasn't supported at all before, so this doesn't fix
a pre-existing security issue, but now that we're making that a valid
configuration, we need to cover this case.

This reflects the changes to the default URL publicly
displayed to the user. It also changes the default
