Every node polls the active override set every 30 seconds, and the
snapshot query selected whole rows, so each poll pulled every plugin's
full source and icon from the database only to compare source_hash and
discard them. With sources allowed up to 8 MiB that is real traffic.
Skip the source and icon columns in the sync snapshot and fetch source by
row id only for plugins whose hash changed. A row never changes source in
place, so the id from the snapshot identifies exactly the text its hash
describes. A failed source load is handled like a compile failure: the
running plugin stays and the next poll retries.
A bare TEXT column holds 64 KiB on MySQL, and the shipped alibaba plugin
is already 73 KB, so uploading an override of it failed with "Data too
long for column 'source'" or was silently truncated. The 1 MiB upload
cap also blocks the larger plugins planned next.
Add model.LongText, a string type that picks longtext on MySQL and text
on PostgreSQL and SQLite through GormDBDataType, and use it for source
and icon. Neither type carries a length, so AutoMigrate leaves an
up-to-date column alone and widens the shipped MySQL text column once
without data loss. Raise the source cap to 8 MiB on the backend and in
the frontend picker, importers and locale strings.
Verified fresh and rc.39-upgrade startups twice each on SQLite, MySQL
5.7.44 and 8.4.11, PostgreSQL 9.6.24 and 17.11; the second start issues
no DDL and a 73 KB source round-trips on every engine.
A New API (type 60) channel proxies another gateway that may host many
task plugins, so the channel setting gains task_extend_plugin_keys; the
single task_plugin_key stays valid there as well. Channel selection,
shared-model candidate rebinding, the task_plugin.bind permission gate,
plugin usage counting and the disable cascade (which now unbinds gateway
channels instead of disabling them) all honour the union of both fields,
and plugins may no longer claim channel type 60 in channelTypes.
Plugins declare meta.upstreams and the host injects ctx.upstream into
every driver hook context. On a type-60 channel the driver addresses its
own prefixed native routes (doubao, alibaba, kling, jimeng) and the host
sends the channel key as a Bearer header for every auth type; polling
threads the channel type through ChannelMeta and tasks keep the key
that submitted them. Only plugins declaring new_api can be bound.
The channel form offers an "Upstream task plugins" selector for type-60
channels, MultiSelect options can carry an icon, and the plugin API docs,
type declarations and schema describe the additive apiVersion 1
extension.
