llvm-project.git/lldb/test/API/commands/expression/error-limit/main.cpp, branch main Unnamed repository; edit this file 'description' to name the repository. [lldb] Allow limiting the number of error diagnostics when parsing an expression 2020-10-13T15:12:43+00:00 Raphael Isemann teemperor@gmail.com 2020-10-13T15:12:07+00:00 02114e15daad7f02e65289412d37334618386ce5 While debugging another bug I found out that we currently don't set any limit for the number of diagnostics Clang emits. If a user does something that generates a lot of errors (like including some long header file from within the expression function), then we currently spam the LLDB output with potentially thousands of Clang error diagnostics. Clang sets a default limit of 20 errors, but given that LLDB is often used interactively for small expressions I would say a limit of 5 is enough. The limit is implemented as a setting, so if a user cares about seeing having a million errors printed to their terminal then they can just increase the settings value.
