Most tests opened a throwaway panel DB with database.InitDB, which runs the
full AutoMigrate + seed on an empty file every time: ~230ms, and ~850ms under
-race because GORM's reflection-heavy migration is what the detector slows
most. internal/web/service does this in ~550 of its 830 tests, so the CI race
job spent ~10 of its ~14.6 minutes re-migrating empty databases.
internal/database/dbtest.InitDB migrates once per test process, then hands
each test its own copy of that file (~130ms under -race) and registers the
CloseDB cleanup. The copy then goes through InitDB like a panel restart, so
every test still starts from the state a fresh install has. Tests that reopen
an existing file, migrate a hand-built legacy DB or target Postgres keep
calling database.InitDB.
Locally under -race: internal/web/service 626s (last CI run) -> 114s,
internal/sub 246s -> 35s.
Reset all traffics and the sorted usage report replied with one Telegram
message per client. A panel with a few hundred clients therefore fired a
burst of sendMessage calls that trips Telegram's per-chat rate limit and
throttles the bot for every user, not just the admin who tapped.
Both reports are now assembled into one string and handed to
SendMsgToTgbot, which already pages long messages.
Two details the batching would otherwise lose: the reset report still
answers (with the reply keyboard removed) when the panel has no clients,
and both reports are HTML-escaped as a whole, because a single stray "<" in
a remark or an email now costs the ~15-client page it lands on instead of
one client's message.
