Jason Molenda f56c0137e2 Small fix to "frame select" sans frame # feature added yesterday.
llvm-svn: 140901
2011-09-30 23:12:14 +00:00
Johnny Chen b62a3be1a2 Add an accompanying option to the 'frame variable -w' command to, instead of watching the variable,
watch the location pointed to by the variable.  An example,

(lldb) frame variable -w write -x 1 -g g_char_ptr
(char *) g_char_ptr = 0x0000000100100860 ""...
Watchpoint created: WatchpointLocation 1: addr = 0x100100860 size = 1 state = enabled type = w
    declare @ '/Volumes/data/lldb/svn/trunk/test/functionalities/watchpoint/hello_watchlocation/main.cpp:21'

...

Also add TestWatchLocation.py test to exercise this functionality.

Jason Molenda 82d4a2b91f Add an additional "frame select" usage where it will re-select the current frame
if no frame is specified.  This is useful to get the source context lines re-displayed
when you need a reminder of where you are in the source currently.

Johnny Chen 5d0434644c Add SB API class SBWatchpointLocation and some extra methods to the SBTarget class to
iterate on the available watchpoint locations and to perform watchpoint manipulations.

I still need to export the SBWatchpointLocation class as well as the added watchpoint
manipulation methods to the Python interface.  And write test cases for them.

Greg Clayton c14ee32db5 Converted the lldb_private::Process over to use the intrusive
shared pointers.

Changed the ExecutionContext over to use shared pointers for
the target, process, thread and frame since these objects can
easily go away at any time and any object that was holding onto
an ExecutionContext was running the risk of using a bad object.

Now that the shared pointers for target, process, thread and
frame are just a single pointer (they all use the instrusive
shared pointers) the execution context is much safer and still
the same size. 

Made the shared pointers in the the ExecutionContext class protected
and made accessors for all of the various ways to get at the pointers,
references, and shared pointers.

Johnny Chen de6bd2432c Add a declaraion info member field to the WatchpointLocation class.
Modify CommandObjectFrame.cpp to populate this field when creating a watchpoint location.
Update the test case to verify that the declaration info matches the file and line number.

Johnny Chen 887062aeb3 Watchpoint WIP:
o Rename from OptionGroupWatchpoint::WatchMode to OptionGroupWatchpoint::WatchType,
  and CommandArgumentType::eArgTypeWatchMode to CommandArgumentType::eArgTypeWatchType.
  Update the sources to reflect the change.

o Add a CreateWatchpointLocation() method to Target class, which is currently not implmeneted
  (returns an empty WatchpointLocationSP object).  Add logic to CommandObjectFrame::Execute()
  to exercise the added API for creating a watchpoint location.

Johnny Chen 3a9838c07b Fix a bug in OptionGroupWatchpoint.cpp where the '-w' option arg parsing result was not checked
to effect an early error return.

Plus add logic to 'frame variable' command object to check that when watchpoint option is on,
only one variable with exact name (no regex) is specified as the sole command arg.

Johnny Chen b1d7529e57 Add OptionGroupWatchpoint.cpp/.h (preparatory work) for hooking up watchpoint to the 'frame variable' comand.
To watch a variable for read/write, issue:

    frame variable -w read_write

Note that '-w' option is not working yet. :-)

Jim Ingham 213b454698 "frame select -r" should return an error if you are already at the top of the stack & try to go up or at the bottom and try to go down.

Jim Ingham 650543f9ba Hold onto a shared pointer to the frame CommandObjectFrameVariable::Execute is
analyzing so it won't get deleted on us if a formatter runs code.

Enrico Granata 0a976141c5 More cleanups ; Separated implementation of FormatManager from class DataVisualization as a front-end by using separate .h/.cpp files - Final aim is to break up FormatManager.h/cpp into several separate files
llvm-svn: 138279
2011-08-22 22:03:47 +00:00
Enrico Granata c482a19294 First round of code cleanups:
- all instances of "vobj" have been renamed to "valobj"
 - class Debugger::Formatting has been renamed to DataVisualization (defined in FormatManager.h/cpp)
   The interface to this class has not changed
 - FormatCategory now uses ConstString's as keys to the navigators instead of repeatedly casting
   from ConstString to const char* and back all the time
   Next step is making the same happen for categories themselves
 - category gnu-libstdc++ is defined in the constructor for a FormatManager
   The source code for it is defined in gnu_libstdcpp.py, drawn from examples/synthetic at compile time
   All references to previous 'osxcpp' name have been removed from both code and file names
Functional changes:
 - the name of the option to use a summary string for 'type summary add' has changed from the previous --format-string
   to the new --summary-string. It is expected that the short option will change from -f to -s, and -s for --python-script
   will become -o

Enrico Granata 379447a7f2 Refactoring of ValueObject::DumpValueObject and 'frame variable', 'target variable' commands to use an Options object instead of passing an ever-increasing number of arguments to the DumpValueObject() method, with the ultimate aim of making that call private implementation

2011-08-12 16:42:31 +00:00
Enrico Granata 22c55d180d *Some more optimizations in usage of ConstString
*New setting target.max-children-count gives an upper-bound to the number of child objects that will be displayed at each depth-level
  This might be a breaking change in some scenarios. To override the new limit you can use the --show-all-children (-A) option
  to frame variable or increase the limit in your lldbinit file
*Command "type synthetic" has been split in two:
  - "type synthetic" now only handles Python synthetic children providers
  - the new command "type filter" handles filters
  Because filters and synthetic providers are both ways to replace the children of a ValueObject, only one can be effective at any given time.
