In #23380, we are changing all occurrences of uri with url in order to
follow the latest URL standard. Previous PRs #25038 and #25045 has
replaced the occurences of uri that has no direct relation with realm.
This commit changes just the model property, which has no API
compatibility concerns.
This is preparatory work towards adding a Topic model.
We plan to use the local variable name as 'topic' for
the Topic model objects.
Currently, we use *topic as the local variable name for
topic names.
We rename local variables of the form *topic to *topic_name
so that we don't need to think about type collisions in
individual code paths where we might want to talk about both
Topic objects and strings for the topic name.
We no longer have to reason about the 12 possible
ways of invoking get_narrow_url. We also avoid
double computation in a couple places.
Finally, we get stricter type checks by just inlining
the calls.
In a previous commit, the frontend of the web app was updated for
URLs with `#narrow/dm/...` for direct messages (group and 1-on-1).
Updates the URLs generated for email notifications and outgoing
webhook notification messages to use the new `/dm/...` format.
Black 23 enforces some slightly more specific rules about empty line
counts and redundant parenthesis removal, but the result is still
compatible with Black 22.
(This does not actually upgrade our Python environment to Black 23
yet.)

This commit updates the urls for personal narrow sent in email
notifications to be of form "{user_id}-{encoded_full_name}" to
make it consistent with the urls that we use for such narrows
in webapp which were recently updated in b4eddad for improving
performance. We encode the full name in the same way that we do in
webapp by replacing the url characters encoded by browser with "-".
Now that we can assume Python 3.6+, we can use the
email.headerregistry module to replace hacky manual email address
parsing.

Moves the encodeHashComponent and decodeHashComponent functions out of
hash_util and into internal_url which belongs to shared. This is to
accommodate sharing of this code with mobile or any other codebases that
do not wish to duplicate logic.
Fixes#2665.
Regenerated by tabbott with `lint --fix` after a rebase and change in
parameters.
Note from tabbott: In a few cases, this converts technical debt in the
form of unsorted imports into different technical debt in the form of
our largest files having very long, ugly import sequences at the
start. I expect this change will increase pressure for us to split
those files, which isn't a bad thing.

This commit adds three `.pysa` model files: `false_positives.pysa`
for ruling out false positive flows with `Sanitize` annotations,
`req_lib.pysa` for educating pysa about Zulip's `REQ()` pattern for
extracting user input, and `redirects.pysa` for capturing the risk
of open redirects within Zulip code. Additionally, this commit
introduces `mark_sanitized`, an identity function which can be used
to selectively clear taint in cases where `Sanitize` models will not
work. This commit also puts `mark_sanitized` to work removing known
false postive flows.
This commit introduces two new functions in 'url_encoding.py' which
centralize two common patterns for constructing redirect URLs. It
also migrates the files using those patterns to use the new
functions.
When you send a message to a bot that wants
to talk via an outgoing webhook, and there's
an error (e.g. server is down), we send a
message to the bot's owner that links to the
message that triggered the error.
The code to produce those links was out of
date.
Now we move the important code to the
`url_encoding.py` library and fix the PM
links to use the more modern style (user_ids
instead of emails). We also replace "subject"
with "topic" in the stream urls.
Extracting this helper library will help us avoid an import loop
between notifications.py and message.py (with bugdown in between).
But in addition to that, it's a more natural model, since some of the
uses for these functions weren't part of the notifications code
anyway.
