The Python sweep. Twelve entries gain profiles; three are deliberately left
short and are explained below.

entry added tests
starlette, litestar, django static, static-tls, json-tls, async-db, crud, api-4, api-16 6 → 13
aiohttp same seven 6 → 13
sanic static, async-db, crud, api-4, api-16 6 → 11
blackbull async-db, api-4, api-16 12 → 15
flask static-tls, crud 11 → 13
bottle json-comp, crud 11 → 13
fastapi, uvicorn, fastpysgi-wsgi, mq-bridge-py crud +1 each

pyronova was already complete.

How the pieces were done

json-tls / static-tls come from the launcher fastapi already used — uvicorn
spawned twice, the second on port+1 with the cert and key. litestar and django
ran uvicorn straight from CMD and now share it. aiohttp uses a second
TCPSite on the same runner, bound by every forked worker.

static bodies are read from disk on every request: Starlette's StaticFiles,
litestar's static router, FileResponse for django and aiohttp, file_stream
for sanic. The encoding is left to the compression each entry already does.

Postgres is asyncpg (psycopg where the entry already used it), one pool per
worker with DATABASE_MAX_CONN divided by the worker count and headroom left
for superuser_reserved_connections. crud runs cache-aside on Redis, 200ms
TTL, explicit delete on update.

Pre-existing bugs fixed along the way

  • mq-bridge-py forks one serving process per core and each opened a pool of
    the whole DATABASE_MAX_CONN. On the crud profile's 62-CPU cpuset that asks
    for 62 × 256 connections of a Postgres running max_connections=256 — the
    same bug hono-bun: size the Postgres pool to the process count #1251 fixed on hono-bun, and crud is exactly the profile that would
    have exposed it.
  • flask answered /pipeline and /baseline11 with text/html. Flask
    defaults a bare body to that and neither handler set a content type, so all
    three Content-Type checks failed.

Left short, on purpose

  • sanic — no json-tls/static-tls. It serves one port per app.run(); the
    documented multi-port form (repeated app.prepare() then Sanic.serve())
    starts without error but 8081 never answers. Its own TLS helper also raises
    KeyError: 'subjectAltName' on the arena's self-signed certificate, so a
    pre-built ssl.SSLContext is needed to get that far at all.
  • blackbull — no crud. The collection route works, but a handler declared
    with a path parameter does not also receive receive/send, so
    /crud/items/{id} can neither read a PUT body nor write a response.
  • fastpysgi-asgi — untouched. It fails 86 checks on unmodified main
    (static, static-tls and TCP fragmentation, all answering empty), so there was
    no clean baseline to add crud against. Needs its own investigation.

Also worth a look

uvicorn, fastpysgi-asgi and fastpysgi-wsgi all preload static file bodies
into a STATIC_FILES dict at startup and serve from memory. The static profiles
forbid that in every mode, including engine, which all three are. I have
not touched their static path — all three already publish static and
static-tls, and fixing it would move those numbers — but it is the same
violation class as go-fasthttp in #1253 and swoole in #1244.

Validation

starlette, litestar, django, aiohttp, fastapi, uvicorn, fastpysgi-wsgi 58/0;
mq-bridge-py 74/0; flask, bottle 56/0; sanic 47/0; blackbull 66/1,
where the one failure is [frag: POST, chunked] and reproduces identically at
63/1 on the unmodified entry.

Still open

robyn (7 profiles), slimeweb and bjoern (3 each), plus the three noted
above.

starlette, litestar, django: the seven missing HTTP/1.1 profiles
009f974 
static, static-tls, json-tls, async-db, crud, api-4 and api-16. Each carried
four endpoints; api-4 and api-16 rotate over /baseline11, /json and /async-db,
so wiring Postgres brings all three profiles with it.

json-tls and static-tls come from the launcher fastapi already uses: it spawns
uvicorn twice, the second on port+1 with the cert and key. litestar and django
ran uvicorn straight from CMD and now go through the same launcher.

Static bodies are read from disk on every request - Starlette's StaticFiles,
litestar's static router, and FileResponse for django, all of which stream the
handle rather than holding the bytes. The encoding is left to the gzip
middleware each entry already mounts.

Postgres goes through asyncpg. uvicorn forks one worker per core and each gets
its own pool, so DATABASE_MAX_CONN is divided by the worker count with headroom
left for superuser_reserved_connections. tags is a JSONB column, so it arrives
as text unless a codec is set.

crud runs cache-aside on Redis with a 200ms TTL and an explicit delete on
update. django wires both lazily on first use: its ASGI application has no
startup hook that runs inside the worker's event loop.

Starlette 1.x takes a lifespan rather than on_startup.

Validation: 58 passed, 0 failed on all three.

  flask                                            static-tls, crud
  bottle                                           json-comp, crud

crud runs cache-aside on Redis everywhere, 200ms TTL, explicit delete on update.
The raw ASGI and WSGI entries key their dispatch on the path up to the last
slash, so /crud/items lands on "/crud/" and /crud/items/<id> on "/crud/items/",
and their method guards had to admit PUT.

bottle had no response compression at all, so json-comp is negotiated per
request in the handler - gzip level 1, nothing without Accept-Encoding.

Two pre-existing problems fixed along the way:

  - mq-bridge-py forks one serving process per core and each opened a pool of
    the whole DATABASE_MAX_CONN. The crud profile hands the container a 62-CPU
    cpuset, so that asked for 62 x 256 connections of a Postgres running
    max_connections=256. The budget is now divided by the worker count with
    headroom for superuser_reserved_connections. This is the same bug #1251
    fixed on hono-bun, and crud is the profile that would have exposed it.

  - flask answered /pipeline and /baseline11 with text/html. Flask defaults a
    bare body to text/html and neither handler set a content type, so all three
    Content-Type checks failed; the profiles want text/plain.

tags is a JSONB column, so it arrives as text unless a codec is set.

Validation: fastapi 58/0, uvicorn 58/0, fastpysgi-wsgi 58/0, mq-bridge-py 74/0,
flask 56/0, bottle 56/0.

👋 Heads up! This PR modifies the following frameworks:

MDA2AV added 2 commits August 22, 2026 01:21
@MDA2AV
sanic, aiohttp: the missing HTTP/1.1 profiles
671061a 
  aiohttp   static, static-tls, json-tls, async-db, crud, api-4, api-16  (6 -> 13)
  sanic     static, async-db, crud, api-4, api-16                        (6 -> 11)

api-4 and api-16 rotate over /baseline11, /json and /async-db, so wiring
Postgres brings all three profiles with it.

aiohttp gets json-tls and static-tls from a second TCPSite on 8081 over the same
runner. Every forked worker binds it exactly as they all bind 8080, so the
listener is spread rather than parked on one process.

sanic does not get them. It serves one port per app.run(); the documented
multi-port form - repeated app.prepare() then Sanic.serve() - starts without
error but the 8081 listener never answers, with or without a per-listener worker
count. Its own TLS helper also raises KeyError on the arena's self-signed
certificate, which has no subjectAltName, so a pre-built ssl.SSLContext is
needed to get that far at all. Rather than ship a listener that does not serve,
the two profiles are left unsubscribed.

Static bodies are read from disk on every request - FileResponse for aiohttp,
file_stream for sanic - and the encoding is left to the compression each entry
already does.

Postgres goes through asyncpg, one pool per worker with DATABASE_MAX_CONN
divided by the worker count and headroom left for
superuser_reserved_connections. crud runs cache-aside on Redis, 200ms TTL,
explicit delete on update. tags is a JSONB column, so it arrives as text unless
a codec is set.

Validation: aiohttp 58/0, sanic 47/0.
@MDA2AV
blackbull: async-db, api-4 and api-16
7b7b3be 
api-4 and api-16 rotate over /baseline11, /json and /async-db, so wiring
Postgres brings all three. asyncpg, one pool per listener process, opened lazily
because launcher.py starts a process per port and there is no startup hook that
runs inside each one's event loop. The budget is divided by the worker count
with headroom for superuser_reserved_connections.

crud is deliberately left out. The collection route works, but a handler
declared with a path parameter does not also receive `receive`/`send`, so
/crud/items/{id} can neither read a PUT body nor write its own response - it
answered with an empty body. Shipping half of crud would fail validation, so it
is not subscribed.

Worth noting for anyone extending this entry: handlers that take `send` must
write the response themselves; a returned Response is silently ignored.

Validation: 66 passed, 1 failed - up from 63 passed, 1 failed on the unmodified
entry. The failure is [frag: POST, chunked], 1 of 140 offsets, and reproduces
identically without these changes.
