Summary
When Ghidra doesn't finish importing and analyzing a target within its startup deadline, REA reports
provider_timeoutwith the generic "Analysis took too long. Try a smaller request, then runrea doctorif it continues." For a large binary that's the wrong advice: the request isn't too big, the deadline is too short, andrea doctorreports Ghidra as healthy. The setting that controls it,REA_GHIDRA_STARTUP_TIMEOUT_MS, is only mentioned indocs/installation.md.A Ghidra startup timeout now names the deadline that was applied and the settings that change it.
Fixes #4241. The memory half of the issue landed in
d52a488(from #4275). This PR covers its second request. The optional third idea, surfacing analyzer messages like "Untested Go version" as limitations, isn't included.Problem and expected behavior
Smallest trigger:
REA_GHIDRA_STARTUP_TIMEOUT_MS=5000 rea inspect "$(command -v node)" --provider ghidra --json.Expected: the error says which deadline elapsed and how to change it, without sending the user to
rea doctor. A timeout on an individual bridge request is a different deadline and should keep its current wording.Hopper already does this: its startup timeout remediation names
REA_HOPPER_STARTUP_TIMEOUT_MS. Ghidra's equivalent setting is never mentioned in its timeout error.Change and scope
GhidraProviderClient.ts: atimeoutfailure carrying the startup-deadline message now gets a user message naming the applied deadline andREA_GHIDRA_STARTUP_TIMEOUT_MS, plus remediation to raise it or skip expensive analyzers withREA_GHIDRA_DISABLED_ANALYZERS. The remediation also notes that the MCP client's own tool-call timeout is separate.GhidraSessionError.ts: the five places that raise the startup timeout (GhidraClient,GhidraClientStartup, and two inGhidraSocketConnection) share oneGHIDRA_STARTUP_DEADLINE_ELAPSEDconstant, so the projection can't drift from them.AnalysisTimeoutErroraccepts an optional provider-specificuserMessageandremediationAction, and the error presentation uses them when present. Every other timeout keeps its current text.docs/installation.md: notes the new guidance next to theREA_GHIDRA_STARTUP_TIMEOUT_MSdescription.Bridge request deadlines and the per-file auto-analysis deadline (
analysis_timeout) are unchanged.Follow the contribution scope.
