Completes the boolean fix: only literal "true"/"false" are accepted, with no
case folding, so "True"/"TRUE" are rejected. Drop strings.ToLower. Keep
TrimSpace so a config value with surrounding whitespace still parses; only the
case folding was invented leniency.
Dead, vestigial, and over-built code with no behavior change (except the
bool-vocabulary trim, a deliberate behavior tightening):
- httpdl: drop the vestigial sort+copy in validSegs (work-stealing was
removed in 270812d, so segments always tile [0,total) ascending now);
validate order in place, which also rejects a scrambled sidecar. Inline
the endOff() accessor to s.end.
- cli: shrink the boolean vocabulary to true/false, which is all that's
accepted. The invented yes/no/1/0/on/off spellings are gone, so e.g.
--enable-dht=yes (or yes in got.conf) is now a usage error.
- download: remove the dead, never-called Stat.Done() method.
- progress: drop speed(), a pure alias of humanSize; call humanSize directly.
- main: replace the jobsHolder mutex box with atomic.Pointer[[]job] for the
forced-exit session save; the capability stays, the lock and type go.
- bt: collapse isAddrInUse's X||X (missinggo.IsAddrInUse is that exact
string match); drop the now-unused missinggo import (tidy -> indirect).
- option: note that prealloc and falloc are identical here.
Surface area, not the machinery, was the problem: 16 flags crowded the
bare --help. Re-tag so basic shows only the 10 outcome-changing flags;
every other flag still works behind --help=<group>.
- cut --bt-metadata-timeout, an invented flag with no real counterpart. Keep
its 60s magnet-metadata stall as a fixed internal default (bt.go), not a
user knob.
- fix the parallelism footgun: a bare `got URL` used min(split,x)=1
connection. When -x is unset, let --split drive per-host connections
(capped at 16), so `got URL` gets 5 and `-s16` gets 16. An explicit -x
is honored verbatim, including -x1. Locked by TestHTTPConnDefault.
- -s is the per-download speed dial now, so it moves to basic; -x (a
per-server cap) moves to the http group. -j help says "files at once,
not connections within one file".
