# <Title: one line, the change, not the complaint>
|
|
|
|
**Status:** draft · **Decision:** pending | submitted <PR link> | interim in Aurora | dropped <why> · **Target:** openwrt/luci `<branch>` | uhttpd | rpcd | eamonxg feed · **Date:** <YYYY-MM-DD>
|
|
|
|
## Problem
|
|
|
|
Two or three sentences: what happens today, on which request, with the
|
|
measured cost (from `dispatch-cost.md` or a named bench run). One sentence on
|
|
who pays (every navigation / every session / every install).
|
|
|
|
## Evidence
|
|
|
|
| # | fact | where |
|
|
|---|---|---|
|
|
| 1 | … | `openwrt/luci@<branch> modules/luci-base/ucode/http.uc:499` |
|
|
| 2 | … | `uhttpd file.c:344` |
|
|
|
|
Unknowns (not yet verified) listed here, each with the command that settles it.
|
|
|
|
## Today
|
|
|
|
```mermaid
|
|
sequenceDiagram
|
|
participant B as Browser
|
|
participant U as uhttpd
|
|
participant D as CGI dispatcher (ucode)
|
|
B->>U: GET …
|
|
U->>D: fork + exec (2 ms) + import (37 ms)
|
|
D-->>B: 200, Cache-Control: no-cache
|
|
```
|
|
|
|
Label edges with cost (ms, bytes, RTT). One diagram per mechanism.
|
|
|
|
## Proposal
|
|
|
|
```mermaid
|
|
flowchart LR
|
|
A[before] -->|change| B[after]
|
|
```
|
|
|
|
Change sketch: exact file and function, approximate size in lines, the new
|
|
headers/config/API. Behaviour on 23.05 / 24.10 / 25.12 / master. What stays
|
|
byte-identical for users who do not opt in.
|
|
|
|
## Alternatives considered
|
|
|
|
Each in one line with why it loses (measured or structural).
|
|
|
|
## Measurement plan
|
|
|
|
Before/after commands (`bench-dispatch.sh`, `bench.mjs`, `bench-fullload.mjs`),
|
|
the numbers expected to move, the device class. "not measured yet" is a
|
|
valid entry; an invented number is not.
|
|
|
|
## Interim in Aurora
|
|
|
|
What this theme (or the eamonxg feed) can do without upstream, and what it
|
|
cannot; link the `/luci-change` plan if one exists.
|
|
|
|
## Submission
|
|
|
|
Repository and branch, commit granularity (one logical change), cover-letter
|
|
contents: problem, measurement before/after with device, compatibility
|
|
statement, test performed.
