Upstream ckpool-solo stubs out send_api_response as a no-op, so the stratifier socket accepts commands like poolstats/users/workers but never writes anything back — kamado-api always gets EOF. Replace the stub with a real implementation: serialize the json_t with json_dumps, write via send_unix_msg, and free. The stratum_loop retry label handles socket cleanup.
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:

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:
- Fixes needed before they land upstream (and only after attempting to submit upstream first).
- Kamado-specific behavior changes that would not be accepted upstream —
e.g. tighter integration hooks with
kamado-api. - 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:
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.
