[PATCH] D85705: Add a "Trace" plug-in to LLDB to add process trace support in stages.

[Fangrui Song via Phabricator via llvm-commits]

MaskRay added inline comments.


================
Comment at: lldb/source/Target/TraceSettingsParser.cpp:123
+  if (schema.empty()) {
+    std::ostringstream schema_builder;
+    schema_builder << "{\n \"trace\": ";
----------------
This requires `sstream`. Fixed.


================
Comment at: lldb/source/Target/TraceSettingsParser.cpp:128
+    std::string plugin_schema(GetPluginSchema());
+    plugin_schema = std::regex_replace(plugin_schema, std::regex("\n"), "\n  ");
+    schema_builder << plugin_schema << ",\n";
----------------
The replacement here looks strange.

`<regex>` implementations tend to be large, slow and buggy. It'd be best if <regex> can be avoided. (llvm has llvm/Support/Regex.h)
