>From 0dd1b3f474ba2744acd5759699120f9f517a1514 Mon Sep 17 00:00:00 2001 From: Jonas Devlieghere <[email protected]> Date: Mon, 29 Jun 2026 15:24:20 -0700 Subject: [PATCH] [lldb] Add a GitHub bug reporter Add a BugReporter plugin that files a diagnostics bundle as an llvm/llvm-project GitHub issue. File() renders a short Markdown body from the Diagnostics::Report (version, host, invocation, and a pointer to the bundle directory to attach), truncates it under a GET-safe URL length on a UTF-8 character boundary, and opens a pre-filled issues/new page with Host::OpenURL. It is gated by LLDB_ENABLE_GITHUB_BUG_REPORTER (default on) and registers ahead of the no-op fallback, so it is the default destination for "diagnostics report" while a downstream tree can still register its own reporter ahead of it. --- .../Commands/CommandObjectDiagnostics.cpp | 5 +- .../source/Plugins/BugReporter/CMakeLists.txt | 7 ++ .../BugReporter/GitHub/BugReporterGitHub.cpp | 66 +++++++++++++++++++ .../BugReporter/GitHub/BugReporterGitHub.h | 33 ++++++++++ .../Plugins/BugReporter/GitHub/CMakeLists.txt | 9 +++ lldb/test/Shell/Diagnostics/TestReport.test | 2 +- llvm/docs/ReleaseNotes.md | 2 + 7 files changed, 121 insertions(+), 3 deletions(-) create mode 100644 lldb/source/Plugins/BugReporter/GitHub/BugReporterGitHub.cpp create mode 100644 lldb/source/Plugins/BugReporter/GitHub/BugReporterGitHub.h create mode 100644 lldb/source/Plugins/BugReporter/GitHub/CMakeLists.txt diff --git a/lldb/source/Commands/CommandObjectDiagnostics.cpp b/lldb/source/Commands/CommandObjectDiagnostics.cpp index c8e50ac7c0b2a..4b02f3b337224 100644 --- a/lldb/source/Commands/CommandObjectDiagnostics.cpp +++ b/lldb/source/Commands/CommandObjectDiagnostics.cpp @@ -194,8 +194,9 @@ class CommandObjectDiagnosticsReport : public CommandObjectParsed { Stream &out = result.GetOutputStream(); out << "Bug report written to " << directory->GetPath() << "\n"; - out << "WARNING: the report may contain file paths, command history and " - "program data.
