satoshi 36c08647e2 ckpool: expose bestever in runtime socket JSON
Upstream ckpool tracks user/worker best_ever across block solves but
only emits it in the on-disk users.json/workers.json persistence files,
not in the runtime socket API (userinfo() / workerinfo() in
stratifier.c). Consumers that poll the socket — like kamado-api — see
bestdiff reset to zero on every block solve via reset_bestshares()
with no all-time field to fall back on. That is the "best share stuck
at zero after a block" UX we want to fix in Kamado.

0001-expose-bestever-in-runtime-json.patch adds bestever to the two
JSON_CPACK calls so the UI can show current-round and all-time side
by side. No behavioral change, no impact on share validation or block
handling. Candidate for upstreaming.

Also surfaces BestEver in api/internal/ckpool types (User, Worker).
Gracefully degrades to 0 on an unpatched ckpool.

# CKPool Patches
Patches applied on top of the upstream CKPool commit pinned in `../CKPOOL_COMMIT`.
Patches are applied in alphabetical order by filename. Use a numeric prefix to enforce ordering:
- `0001-short-description.patch`
- `0002-another-fix.patch`
## Current state
One Kamado patch is applied on top of the pinned upstream commit:
| Patch | What it does |
| --------------------------------------------- | -------------------------------------------------------------------------------------- |
| `0001-expose-bestever-in-runtime-json.patch` | Adds `bestever` field to the `users` / `workers` runtime socket JSON |
### Why 0001 matters
Upstream tracks `best_ever` internally in `user_instance_t` / `worker_instance_t`
and zeroes `best_diff` on every block solve via `reset_bestshares()`. That
is correct: `bestdiff` is "best share in the current round". But the runtime
socket API (`userinfo()` / `workerinfo()` in `stratifier.c`) only emits
`bestdiff`, so any consumer that talks to the socket — like `kamado-api`
sees the best share reset to 0 after every block and has no all-time field
to fall back on. The on-disk `users.json` / `workers.json` persistence files
do include `bestever`, but polling those is racy and lags the socket.
This patch adds `bestever` to the runtime JSON so the UI can show both
"this round" and "all-time" best share side by side. No behavioral change
to share validation or block handling. Candidate for upstreaming.
Beyond this patch, the pinned upstream commit (`cfb0f83b`, tagged as
version 1.0) already includes every fix that Bassin issue #29 asked to
backport, plus several improvements:
| Upstream commit | What it fixes |
| --------------- | -------------------------------------------------------------- |
| `a439cf96` | workbase_id double increment bug |
| `590fb2a2` | Extended timeouts for low-powered miners (NerdMiner, ESP32) |
| `b13f3eee` | Configurable `dropidle` timeout (exposed via our env var) |
| `66db3aa3` | Better vardiff for bursty hashers |
| `130c755d` | Fix unlikely fopen segfault |
| `0bd3d751` | Consistent error field in mining.submit rejections |
| `988b2687` | Version 1.0 — longstanding stability bump |
Kamado therefore starts from a CKPool that is strictly ahead of what Bassin
ships today.
## When to add a patch
Use this directory for:
1. Fixes needed before they land upstream (and only after attempting
to submit upstream first).
2. Kamado-specific behavior changes that would not be accepted upstream —
e.g. tighter integration hooks with `kamado-api`.
3. Temporary workarounds with a clear removal plan, documented in the
patch commit message.
Do NOT use this directory for:
- Pure configuration changes (expose via the entrypoint env vars instead).
- Build system tweaks (put those in the Dockerfile).
## Creating a patch
From a clean clone of upstream at the pinned commit:
```sh
git clone https://bitbucket.org/ckolivas/ckpool.git
cd ckpool
git checkout $(cat /path/to/KamadoPool/ckpool/CKPOOL_COMMIT)
# ... make your changes ...
git diff > /path/to/KamadoPool/ckpool/patches/0001-my-fix.patch
```
The Dockerfile applies each `*.patch` file in this directory with
`git apply --verbose` during the build.
