Attaching a debugger will also change the behavior of concurrent code.
- shaklee3 8y agoSo does repl, to be fair.
- xxs 8y agoThis would depend on the language/compiler/linker - take Java (which the article is about). Attaching debugger does nothing prior to adding a breakpoint. The breakpoint would cause the method to be deoptimized, executed in the interpreter. Removing the breakpoint would allow the method to be optimized again. Now obviously during stepping in, the thread would be blocked and not highly concurrent. However print statements just bare the concurrency.
- a_t48 8y agoLet's face it - concurrency sucks to debug in general.
