6a958619a0 Automatically turn debug mode on/off when adding/removing debuggees. 
This allows most of the tests to run without the -d command-line flag.

Now a compartment is in debug mode if
 * JSD1 wants debug mode on, thanks to a JS_SetDebugMode* call; OR
 * JSD2 wants debug mode on, because a live Debug object has a debuggee
   global in that compartment.

Since this patch only adds the second half of the rule, JSD1 should be
unaffected.

The new rule has three issues:

1. When removeDebuggee is called, it can cause debug mode to be turned
   off for a compartment. If any scripts from that compartment are on
   the stack, and the methodjit is enabled, returning to those stack
   frames will crash.

2. When a Debug object is GC'd, it can cause debug mode to be turned off
   for one or more compartments. This causes the same problem with
   returning to deleted methodjit code, but the fix is different: such
   Debug objects simply should not be GC'd.

3. Setting .enabled to false still does not turn off debug mode
   anywhere, so it does not reduce overhead as much as it should.

A possible fix for issue #1 would be to make such removeDebuggee calls
throw.  The fix to issues #2 and #3 is to tweak the rule--and to tweak
the rule for Debug object GC-reachability.

d48b27e096 Rearrange some stuff. This way more js::Debug methods can be private, without making anything new public; all the event dispatch code is in one place; and we avoid having JSCompartment methods in jsdbg.cpp. 2011-04-21 14:44:53 -05:00

72c7701093 Bug 634155: Account for NewCompartment's memory, and change allocation APIs (r=nnethercote) 
This changes the allocation API, in the following way:

  js_malloc -> {cx->,rt->,OffTheBooks::}malloc
  js_calloc -> {cx->,rt->,OffTheBooks::}calloc
  js_realloc -> {cx->,rt->,OffTheBooks::}realloc
  js_free -> {cx->,rt->,Foreground::,UnwantedForeground::}free
  js_new -> {cx->,rt->,OffTheBooks::}new_
  js_new_array -> {cx->,rt->,OffTheBooks::}new_array
  js_delete -> {cx->,rt->,Foreground::,UnwantedForeground::}delete_

This is to move as many allocations as possible through a JSContext (so that they may be aken into account by gcMallocBytes) and to move as many deallocations to the background as possible (except on error paths).

efd9982808 Bug 561359 - Change JSOP_LAMBDA to apply the method optimization deterministically. In particular, it no longer depends on whether enclosing Blocks have been reified. This prevents incorrect behavior and assertions when a JSOP_LAMBDA, JSOP_INITMETHOD pair apply the method optimization once, populating the property cache, but later the same JSOP_LAMBDA instruction does not (under the old code) apply the optimization. With this patch, if JSOP_LAMBDA pushes the uncloned function once, it always will. r=brendan. 2011-03-14 15:54:34 -05:00
