A request with "timing": true gets queue, confirm and exec times in its answer; with QET_LIVE_PERF_LOG set, QElectroTech also appends one JSON line per request, with the time until the folio is next painted. The qet MCP server logs its side of each live call to the same file. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

/**
|
|
@brief The LiveServer class
|
|
Live mode: an AI assistant, through the qet MCP server, runs scripts on
|
|
the project open in this QElectroTech while the user watches.
|
|
|
|
Three things must all be true before anything can connect: scripting is
|
|
allowed, the "mode direct" setting is on (off by default), and the user
|
|
accepted the warning shown at this start. With the setting off this
|
|
class opens nothing and QElectroTech behaves as if it did not exist.
|
|
|
|
The channel is a QLocalServer only the user's own account can open,
|
|
with a random name and token written to the "live" part of
|
|
qet-assistant.json (AssistantInfo), which the MCP server reads, and
|
|
cleared when the channel closes. One JSON request per connection, one JSON answer back, then
|
|
the server closes the connection; every request carries the token.
|
|
|
|
Requests are never handled inside the socket's readyRead: each is
|
|
queued to the event loop first. QETApp::receiveMessage() learnt why --
|
|
a modal dialog opened from inside a socket handler crashed QElectroTech
|
|
once the socket went away (PR #861).
