Summary
Fixes #5342.
REA_GHIDRA_DISABLED_ANALYZERSis process-wide, but the pre-script checked each name against the analyzers Ghidra registered for the program being imported. Ghidra registers only the installed analyzers whosecanAnalyze(program)accepts the program, so a format-specific name such asObjective-C Message AnalyzerorDemangler Swiftaborted every ELF, PE and plain Mach-O import with a genericexecution_failure.Now a name that an installed analyzer provides but that Ghidra did not register for this program is reported as not applicable and the import continues. A name that no installed analyzer provides still aborts the import, so typos are still caught.
Problem and expected behavior
Smallest trigger (observed on
mainat4eaf3a117with real Ghidra 12.1.4):REA_GHIDRA_DISABLED_ANALYZERS="Objective-C Message Analyzer" rea analyze /usr/bin/true --provider ghidra --jsonexits 1 withexecution_failure; the only mention of the cause is indetails.diagnostics.stdout.text:java.lang.IllegalArgumentException: Unknown Ghidra analyzer for this program: Objective-C Message Analyzer.Expected:
REA_GHIDRA_DISABLED_ANALYZERSand the analyzer.Change and scope
bridge/ghidra/ReaGhidraAnalysisOptions.java: a nameAutoAnalysisManager.getAnalyzerfinds is disabled and read back as before. Otherwise the script checks the name againstClassSearcher.getInstances(Analyzer.class), the same set thatAutoAnalysisManager.initializeAnalyzersfilters bycanAnalyze(program)in Ghidra 12.1.4. That set is only built when a name is unregistered. The script stores a per-name report (rea-ghidra-disabled-analyzers-v1, statusesdisabled/not_applicable) as a program property, and every failure message now names the setting and the analyzer.bridge/ghidra/ReaGhidraBridge.java: returns that report in the handshake asdisabled_analyzers. This follows the existinganalysis_seedspattern.src/ghidra/GhidraDisabledAnalyzers.ts(new): owns the report schema, the fail-closed check against the committed names, and the not-applicable limitation.GhidraProviderClientapplies them. Non-health operations now verify the handshake whenever analyzers are configured. Without that, the outcome check and limitation were skipped for operations such aslist_procedureson non-PE targets.Not-applicable analyzers are recorded in result limitations, not in the committed
analyzer_preset. The analysis profile and its digest are committed before Ghidra imports the target, and they gate snapshot reuse before launch. Applicability is only known after import, so the committedanalyzer_presetkeeps the configured names, and results report the applied preset asApplied analyzer preset: ghidra-default+disabled:Objective-C Message Analyzer(n/a). …. No hardcoded format list. The top-level error for an unknown name is still the genericexecution_failure; the setting and analyzer are named in the Ghidra output carried indetails.diagnostics.Rebased onto
mainee12d517a. Thedocs/installation.mdconflict with98a5e5638keeps its server-wide scope and restart guidance and drops the separate-server workaround, which this fix makes unnecessary.Merged
mainf86206535at8e425dc4d. The earlier test-only commit424584d17fixed a stale assertion intests/boundary/filesystem/jsonOutputOwnership.test.ts.mainhas since fixed the same assertion (#5601), so the merge keepsmain's version and this PR no longer changes that file.Contribution scope: ordinary fix within existing provider boundaries; maintainer scope decision not applicable.
Contract and boundary impact
GhidraDisabledAnalyzers.tsowns the reported outcome.disabled_analyzers, required whenever the setting is configured. The pre-script and bridge ship together. Unset configuration is unchanged.Expected effects (check known effects; use documentation-only on its own).
Unchecked items do not establish absence; leave uncertainties visible.
Evidence and regression coverage
Tests added or updated:
src/ghidra/GhidraProvider.behavior.test.ts: all names disabled (no added limitation); a not-applicable name (operation succeeds, limitation carries the(n/a)preset, committed preset and digest unchanged); a missing report, a report for other names, or a report missing a configured name fails closed before any analysis call; a report the profile did not commit fails closed.src/ghidra/GhidraSessionValues.test.ts: report schema accepts both statuses in configured order and rejects anunknownstatus, an empty list, another format and undeclared fields.scripts/verify/ghidra/seeds.mjs+ReaAnalyzerOptionsRegressionProbe.java(real Ghidra): adds the not-applicable report case and the new unknown-name message.Base reproduction (executed, real Ghidra 12.1.4, ELF

User-visible CLI/MCP output:

Ghidra did not register the (n/a) analyzers for this program, so REA_GHIDRA_DISABLED_ANALYZERS had nothing to disable for them; the analysis profile still commits every configured name.details.diagnostics.stdout.text:java.lang.IllegalArgumentException: REA_GHIDRA_DISABLED_ANALYZERS names Objective-C Mesage Analyzer, which is not an analyzer in this Ghidra installationRemaining proof gaps: Objective-C Mach-O target (analyzer registered and disabled on a real ObjC program) not run; Windows Ghidra lane not run.
