- Renames "Customize Zulip" to "Server configuration".
- Cross-links "Server configuration" with "System and deployment
configuration".
Fixes part of #23984.
The `postfix.mailname` setting in `/etc/zulip.conf` was previously
only used for incoming mail, to identify in Postfix configuration
which messages were "local."
Also set `/etc/mailname`, which is used by Postfix to set how it
identifies to other hosts when sending outgoing email.

These files are not Jinja2 templates, so there's no reason that they needed
to be inside `templates/zerver`. Moving them to the top level reflects their
importance and also makes it feel nicer to work on editing the help center content,
without it being unnecessary buried deep in the codebase.
For descriptive endpoints, such as `/register`, that might raise
Schema Validation errors via `validate_against_openapi_schema`,
omits the OpenAPI schema definition in the error output.
Also omits the error instance definition in the error output
when it is a jsonschema object with over 100 properties. This
means that the test instance for objects, like user settings,
will be printed in the error output, but the test instance for
the entire endpoint will not be printed to the console.
The omitted output can be thousands of lines long making it
difficult to find the initial console output that actually helps
the contributor with debugging.
Adds a section in "Documenting REST API endpoints" about
debugging and understanding these errors that is linked to
in the error console output.
When file uploads are stored in S3, this means that Zulip serves as a
302 to S3. Because browsers do not cache redirects, this means that
no image contents can be cached -- and upon every page load or reload,
every recently-posted image must be re-fetched. This incurs extra
load on the Zulip server, as well as potentially excessive bandwidth
usage from S3, and on the client's connection.
Switch to fetching the content from S3 in nginx, and serving the
content from nginx. These have `Cache-control: private, immutable`
headers set on the response, allowing browsers to cache them locally.
Because nginx fetching from S3 can be slow, and requests for uploads
will generally be bunched around when a message containing them are
first posted, we instruct nginx to cache the contents locally. This
is safe because uploaded file contents are immutable; access control
is still mediated by Django. The nginx cache key is the URL without
query parameters, as those parameters include a time-limited signed
authentication parameter which lets nginx fetch the non-public file.
This adds a number of nginx-level configuration parameters to control
the caching which nginx performs, including the amount of in-memory
index for he cache, the maximum storage of the cache on disk, and how
long data is retained in the cache. The currently-chosen figures are
reasonable for small to medium deployments.
The most notable effect of this change is in allowing browsers to
cache uploaded image content; however, while there will be many fewer
requests, it also has an improvement on request latency. The
following tests were done with a non-AWS client in SFO, a server and
S3 storage in us-east-1, and with 100 requests after 10 requests of
warm-up (to fill the nginx cache). The mean and standard deviation
are shown.
| | Redirect to S3 | Caching proxy, hot | Caching proxy, cold |
| ----------------- | ------------------- | ------------------- | ------------------- |
| Time in Django | 263.0 ms ± 28.3 ms | 258.0 ms ± 12.3 ms | 258.0 ms ± 12.3 ms |
| Small file (842b) | 586.1 ms ± 21.1 ms | 266.1 ms ± 67.4 ms | 288.6 ms ± 17.7 ms |
| Large file (660k) | 959.6 ms ± 137.9 ms | 609.5 ms ± 13.0 ms | 648.1 ms ± 43.2 ms |
The hot-cache performance is faster for both large and small files,
since it saves the client the time having to make a second request to
a separate host. This performance improvement remains at least 100ms
even if the client is on the same coast as the server.
Cold nginx caches are only slightly slower than hot caches, because
VPC access to S3 endpoints is extremely fast (assuming it is in the
same region as the host), and nginx can pool connections to S3 and
reuse them.
However, all of the 648ms taken to serve a cold-cache large file is
occupied in nginx, as opposed to the only 263ms which was spent in
nginx when using redirects to S3. This means that to overall spend
less time responding to uploaded-file requests in nginx, clients will
need to find files in their local cache, and skip making an
uploaded-file request, at least 60% of the time. Modeling shows a
reduction in the number of client requests by about 70% - 80%.
The `Content-Disposition` header logic can now also be entirely shared
with the local-file codepath, as can the `url_only` path used by
mobile clients. While we could provide the direct-to-S3 temporary
signed URL to mobile clients, we choose to provide the
served-from-Zulip signed URL, to better control caching headers on it,
and greater consistency. In doing so, we adjust the salt used for the
URL; since these URLs are only valid for 60s, the effect of this salt
change is minimal.
Moving `/user_avatars/` to being served partially through Django
removes the need for the `no_serve_uploads` nginx reconfiguring when
switching between S3 and local backends. This is important because a
subsequent commit will move S3 attachments to being served through
nginx, which would make `no_serve_uploads` entirely nonsensical of a
name.
Serve the files through Django, with an offload for the actual image
response to an internal nginx route. In development, serve the files
directly in Django.
We do _not_ mark the contents as immutable for caching purposes, since
the path for avatar images is hashed only by their user-id and a salt,
and as such are reused when a user's avatar is updated.
The authenticate_by_username limit of 5 attempts per 30 minutes can get
annoying in some cases where the user really forgot their password and
should be allowed to keep trying with admin approvial - so we should
document the command that allows unblocking them.
Changes all the uses of the word "operators" to "filters" in
contributor docs, help center, and landing page to align with
the updated help center documentation.
Moves files in `templates/zerver/help/include` that are used
specifically for API documentation pages to be in a new directory:
`templates/zerver/api/include`.
Adds a boolean parameter to `render_markdown_path` to be used
for help center documentation articles.
Also moves the test file `empty.md` to the new directory since
this is the default directory for these special include macros
that are used in documentation pages.
Moves files in `templates/zerver/help/include` that are used
specifically for integrations documentation to be in a new
directory: `templates/zerver/integrations/include`.
Adds a boolean parameter to `render_markdown_path` to be used
for integrations documentation pages.
The documentation included the full policy for the file uploads
bucket, but only one additional statement for the avatars bucket; the
reader needed to assemble the full policy themselves.
Switch to explicitly providing the full policy for both.
Fixes#23110.
Fixes#23517.
While this feature was added to Zulip very early, it has been troubled
for most of that time; it never looked great visually, had a lot of
implementation complexity around resize.js, and has a weird model (a
setting that changes the UI only in certain window sizes).
This option is not commonly used; while a significant portion of users
have it enabled, many of them just don't use window sizes where it
actually has an effect. So it's not clear that it will be missed if
removed; we got very few bug reports when it was completely broken for
a few days after we first integrated the new left sidebar private
messages design.
Even with it no longer being broken, it does not work very well with
the addition of the new PMs section in the left sidebar. (Having two
scrollbars in the sidebar looks quite awkward.) The new private
messages section in the left sidebar also addresses some of the use
cases for always keeping the Users list always visible, even in narrow
windows.
This option is only removed from frontend for now. To make this
decision easily reversible, the backend code of this feature
is still kept.
Since this is being moved to admin-facing documentation, also adds a
paragraph about the main concern with enabling this on a server that's
not zulip.com.
Inspired by #23377. We document a convention maneuver to avoid adding
noop migrations, which involves modifying the latest migration related
to the fields in question.

Updates the current 6.0 release notes to include information about
the rename to "Recent conversations", and updates past references
to "recent topics" to be consistently formatted as "Recent topics".
Replaces instances of "recent topics" in the web-app and documentation
to be "recent conversations".
Renames both `recent-topics.md` files in the help center to be
`recent-conversations.md` and updates/redirects links to new URL.
Does not update instances of "recent topics" in frontend code comments
and does not update the main overview changelog, for now.
Does not change case study text where "recent topics" was referenced
in a quote, but does change generic text references to be "recent
conversations".
This adds a helper based on testing patterns of using the "queries_captured"
context manager with "assert_length" to check the number of queries
executed for preventing performance regression.
It explains the rationale of checking the query count through an
"AssertionError" and prints the queries captured as assert_length does,
but with a format optimized for displaying the queries in a more
readable manner.

Previously, we included all three message edit related settings
("allow_message_editing", "message_content_edit_limit_seconds" and
"edit_topic_policy") in the event data and api response irrespective
of which of these settings were changed. Now, we only include changed
settings and separate events are sent for each setting if more than
one of them is changed.
Note that the previous typed in event_schema.py for
`message_content_edit_limit_seconds` incorrectly did not allow `None`
as a value, which is used to encode no limit.

Renames the filename so that it accurately reflects its contents
given the changes to the "Recommended setup" page in the previous
commit, and updates all links accordingly.
Windows users end up having to follow an odd chain of links because
the recommended installation instructions live on a different
page than the rest of the instructions about the environment setup.
All the tutorials about recommended install prerequisites for each
platform should be on the same page.
This moves the section about using WSL 2 from the advanced setup page
to the recommended environment setup tutorial page.
Renames sidebar and section titles to more accurately reflect the
information in the Recommended setup vs. the Advanced setup page.
Updates relevant text and links accordingly.
Fixes: #13696.
Updates the tutorial in "Writing help center articles: Writing
style" for using `<kbd>` HTML elements when documenting keyboard
shortcuts in help center articles.
Also, adds section about the keyboard tip macro/syntax.
We create "event-filter-instruction.md" and add it to
"create-bot-construct-url.md". This allows the user to keep track of the
supported event types for most of the integrations that implement this
feature. Note that not all integrations use "create-bot-construct-url.md".
We also need to rename "function" to "view_function" to make this change
type-check.
This is relevant to #18392.

This commit brings AzureAD config in line with other backends:
- SOCIAL_AUTH_AZUREAD_OAUTH2_SECRET gets fetched in computed_settings.py
instead of default_settings, consistent with github/gitlab/etc.
- SOCIAL_AUTH_AZUREAD_OAUTH2_KEY gets fetched in default_settings via
get_secret(..., development_only=True) like other social backends, to
allow easier set up in dev environment, in the dev-secrets.conf file.
- The secret gets renamed from azure_oauth2_secret to
social_auth_azuread_oauth2_secret to have a consistent naming scheme with
other social backends and with the SOCIAL_AUTH_AZUREAD_OAUTH2_KEY
name. This is backwards-incompatible.
The instructions for setting it up are updated to fit how this is
currently done in AzureAD.
Creates `zerver.lib.url_redirects.py` to record old and new URLs
for documentation pages that have been renamed/moved and need URL
redirects.
This file is then used by `zproject.urls.py` to redirect links and
by `zerver.test.test_urls.py` to test that all of the old URLs
return a success response with a common page header/text depending
on the type of redirect (help center, policy, or API).
Adds a section to contributor docs on writing documentation for
how to use this redirect system when renaming a help center or api
documentation page.
Fixes#21946. Fixes#17897.
We should rearrange Zulip's developer docs to make it easier to
find the documentation that new contributors need.

This module was originally introduced in 2016 to assist adding mypy
annotations to the project. Back then static type checking was not that
established throughout the codebase, so it was helpful to be able to
print out the types for type checking purposes.
This workflow is no longer helpful for improving type annotations right
now, and it has been unused for a while.

This is not a feature intended to be used outside zulip.com, since it
just sets your server to have the zulip.com landing pages. I think
it's only been turned on by people who were confused by this text.
