feat(obs): make observability.access_log turn the access log off - #1259

Conversation
The key was parsed with a default of true but nothing read it, so the only way to silence access-log lines was the log level, which silences every other info line with them. access_log: false now suppresses every access-log line whatever the level or RUST_LOG; the default keeps today's behaviour. The e2e harness wrote access_log: false into every spawned gateway while the key was inert; it now writes the binary's default unless a spec opts out.

Merge Risk: 🔵 Low · up to Access logging is now configurable and the change looks sound. One test does not guard against duplicate access-log lines. This is a small test-strength gap and can be handled as a follow-up. 🚥 Pre-merge checks | ✅ 6✅ Passed checks (6 passed)

The key used to be inert; now it would silently turn off the access log for anyone raising these specs' log level.

observability.access_logwas parsed (defaulttrue) but nothing read it, so the only way to silence the per-requestproxy request completedlines was lowering the log level, which takes every otherinfoline down with them. This makes the key do what its name says.AccessLog::emitis the single point every access-log line goes through (buffered handlers, deferred stream endings, the head-phase cancel,/v1/realtime, passthrough routes, pre-dispatch rejections), so the switch is one process-wide flag thatinit_tracingsets from the config andemitchecks. It is a check rather than anEnvFilterdirective so noRUST_LOGspelling can bring the lines back.Behaviour change:
access_log: falsenow writes no access-log line at all, whateverlog_level/RUST_LOGsay; every other log line is unaffected.access_log: true(the default, and what an omitted key or block means) behaves exactly as before, including level filtering: the line is still aninfoevent. A deployment that hadaccess_log: falsein its config while it was inert will stop getting access-log lines after upgrading; remove the key or set it totrueto keep them.config.example.yaml/config.managed.yamlnow annotate the key. The public chart (charts/aisix) already carriesobservability.access_log: true, so nothing changes there.Tests: a new DP e2e (
access-log-switch-e2e) spawns one gateway withaccess_log: falseand one with the default, both atinfo, and drives a buffered chat, a streamed chat and a pre-dispatch 400 through each. Off, it stops the gateway (which drains the log queue) and asserts no access-log line, while the boot line and the per-attemptprovider call completedlines of the same requests are present. Default, each request has its line. The off case fails with the check removed. The e2e harness used to writeaccess_log: falseinto every spawned gateway; it now writes the binary's default and specs opt out withaccessLog: false.🤖 Generated with Claude Code
Summary by CodeRabbit
observability.access_log. Access logging is enabled by default and writes one entry per request at theinfolevel.info. WhenRUST_LOGis set, it determines the filter; otherwise,log_levelapplies.
