### Debugging

|
|
|
|
|
|
|
|
|
#### Stack trace
|
|
|
|
|
|
|
|
|
|
It `mozglue/misc/StackWalk.cpp` add
|
|
|
|
|
|
|
|
|
|
```c++
|
|
|
|
|
#define MOZ_DEMANGLE_SYMBOLS 1
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
In native code use
|
|
|
|
|
|
|
|
|
|
```c++
|
|
|
|
|
nsTraceRefcnt::WalkTheStack(stderr);
|
|
|
|
|
```

If the stack trace is still mangled `cat` it to `tools/rb/fix_linux_stack.py`
|
|

#### [Logging](https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Gecko_Logging)
|
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
MOZ_LOG=nsHttp:5
|
|
|
|
|
```
|
|
|
|
|
Module name is a string passed to the `mozilla::LazyLogModule` of the corresponding component, e.g.:
|
|
|
|
|
|
|
|
|
|
```c++
|
|
|
|
|
LazyLogModule gHttpLog("nsHttp");
|
|
|
|
|
```
