Script Panel Refactoring
- Adopt JSD2 (get rid of all JSD1 APIs)
- Support remote debugging
JSD2 API Requirements
The following list summarizes the high-level features that Firebug needs to support. It should be verified that all the features can re-implemented on top of JSD2 before starting the refactoring.
- List of scripts available on selected tab (including static, events and evaluated scripts) including iframes →
- Stepping (into, over, out, resume, current line)
- Support for
- Support for breakpoints (add, remove, enable, disabled, conditional, list of existing breakpoints) →
- Recognize executable lines
- Dynamic eval in a frame (used e.g. by the Watch Side Panel when the debugger is halted) →
- Get stack frames (including passed arguments) →
- Scope chain variable exploring (with & closure scopes). It should be possible to see all values. →
- Break on next call
- Profiling (was part of JSD1)
- Tracking (break on) throw/catch/error →
- Tracking (monitoring) function calls
- Freezing page UI if debugger is halted (including timeouts, intervals and worker threads)
Not Ready in JSD2
- There is not source for evals.
- new Function scripts?
- Meta bug: Implement a script Debugger
- As soon as this one is fixed
- Profiling is unrelated to JSD2. What is the plan here?
- Tracking (break on) throw/catch/error; also what is the plan?
Script Panel Architecture
The Script panel needs to be built on top of JSD2, remote protocol and Firebug remote architecture. Remoting is already supported by HTTP Monitor and both components should share the same approaches and API.
