Szymon Malewski 73f0deef6d alternator: optional stripping of http response headers
In Alternator's HTTP API, response headers can dominate bandwidth for
small payloads. The Server, Date, and Content-Type headers were sent on
every response but many clients never use them.

This patch introduces three Alternator config options:
  - alternator_http_response_server_header,
  - alternator_http_response_disable_date_header,
  - alternator_http_response_disable_content_type_header,
which allow customizing or suppressing the respective HTTP response
headers. All three options support live update (no restart needed).
The Server header is no longer sent by default; the Date and
Content-Type defaults preserve the existing behavior.

The Server and Date header suppression uses Seastar's
set_server_header() and set_generate_date_header() APIs added in
https://github.com/scylladb/seastar/pull/3217. This patch also
fixes deprecation warnings from older Seastar HTTP APIs.

Tests are in test/alternator/test_http_headers.py.

Building User Documentation

Prerequisites

  • Python
  • poetry
  • make

See the ScyllaDB Sphinx Theme prerequisites to check which versions of the above are currently required.

Mac OS X

You must have a working Homebrew in order to install the needed tools.

You also need the standard utility make.

Check if you have these two items with the following commands:

brew help
make -h

Linux Distributions

Building the user docs should work out of the box on most Linux distributions.

Windows

Use "Bash on Ubuntu on Windows" for the same tools and capabilities as on Linux distributions.

Building the Docs

  1. Run make preview in the docs/ directory to build the documentation.
  2. Preview the built documentation locally at http://127.0.0.1:5500/.

Cleanup

You can clean up all the build products and auto-installed Python stuff with:

make pristine
