Debugging Tremor¶
This is a short canned synopsis of debugging tremor.
rust-lldb¶
We use rust-lldb, to drive breakpoint debugging in tremor.
Alternately, rust integration with IntelliJ CLION also offers interactive breakpoint debugging in an IDE environment.
Setup on Mac OS X¶
rust-lldb ships with rust so no added tooling is required.
Preparing tremor for debugging¶
$ rust-lldb target/debug/tremor
(lldb) command script import "/Users/dennis/.rustup/toolchains/stable-x86_64-apple-darwin/lib/rustlib/etc/lldb_rust_formatters.py"
(lldb) type summary add --no-value --python-function lldb_rust_formatters.print_val -x ".*" --category Rust
(lldb) type category enable Rust
(lldb) target create "target/debug/tremor"
Current executable set to 'target/debug/tremor' (x86_64).
(lldb)
Run tremor under the debugger¶
(lldb) run
Run to breakpoint for malloc related issues¶
(lldb) br set -n malloc_error_break
(lldb) run
Take a backtrace ( stacktrace ) upon hitting a breakpoint¶
(lldb) bt
List breakpoints¶
(lldb) br l
Quit lldb¶
(lldb) quit
