An improved var_dump() function, stack traces for Notices, Warnings, Errors
and Exceptions to highlight the code path to the error

Writes every function call, with arguments and invocation location to disk.
Optionally also includes every variable assignment and return value for
each function.

To show which parts of your code base are executed when running unit tests
with PHP Unit.

Release notes
Version 2.1.0beta1
(beta)
Sun, Jan 03, 2010 - xdebug 2.1.0beta1

+ Added features:
- Added error display collection and suppressions.
- Added the recording of headers being set in scripts.
- Added variable assignment tracing.
- Added the ability to turn of the default overriding of var_dump().
- Added "Scream" support, which disables the @ operator.
- Added a trace-file analysing script.
- Added support for debugging into phars.
- Added a default xdebug.ini. (Patch by Martin SchuhfuÃ?
<martins@spot-media.de>)
- Added function parameters in computerized function traces.
- PHP 5.3 compatibility.
- Improved code coverage accuracy.

+ New functions:
- xdebug_get_formatted_function_stack(), which returns a formatted function
stack instead of displaying it.
- xdebug_get_headers(), which returns all headers that have been set in a
script, both explicitly with things like header(), but also implicitly
for things like setcookie().
- xdebug_start_error_collection(), xdebug_stop_error_collection() and
xdebug_get_collected_errors(), which allow you to collect all notices,
warnings and error messages that Xdebug generates from PHP's
error_reporting functionality so that you can output them at a later
point in your script by hand.

+ New settings:
- xdebug.collect_assignments, which enables the emitting of variable
assignments in function traces.
- xdebug.file_line_format, to generate a link with a specific format for
every filename that Xdebug outputs.
- xdebug.overload_var_dump, which allows you to turn off Xdebug's version
of var_dump().
- xdebug.remote_cookie_expire_time, that controls the length of a
remote debugging session. (Patch by Rick Pannen <pannen@gmail.com>)
- xdebug.scream, which makes the @ operator to be ignored.

+ Changes:
- Added return values for xdebug_start_code_coverage() and
xdebug_stop_code_coverage() to indicate whether the action was
succesfull. xdebug_start_code_coverage() will return TRUE if the call
enabled code coverage, and FALSE if it was already enabled.
xdebug_stop_code_coverage() will return FALSE when code coverage wasn't
started yet and TRUE if it was turned on.
- Added an optional argument to xdebug_print_function_stack() to display
your own message. (Patch by Mikko Koppanen).
- All HTML output as generated by Xdebug now has a HTML "class" attribute
for easy CSS formatting.

- Removed features:
- Support for PHP versions lower than PHP 5.1 have been dropped.
- The PHP3 and GDB debugger engines have been removed.

= Fixed bugs:
- Fixed support for showing $this in remote debugging sessions.
- Fixed bug in formatting the display of "Variables in the local scope".
- Possible fix for a threading issue where the headers gathering function
would create stack overflows.
- Possible fix for #324: xdebug_dump_superglobals() only dumps superglobals
that were accessed before, and #478: XDebug 2.0.x can't use %R in
xdebug.profiler_output_name if register_long_arrays is off.

- Fixed bug #505: %s in xdebug.trace_output_name breaks functions traces.
- Fixed bug #494: Private attributes of parent class unavailable when
inheriting.
- Fixed bug #486: feature_get -n breakpoint_types returns out of date list.
- Fixed bug #476: Xdebug doesn't support PHP 5.3's exception chaining.
- Fixed bug #472: Dead Code Analysis for code coverage messed up after goto.
- Fixed bug #470: Catch blocks marked as dead code unless executed.
- Fixed bug #469: context_get for function variables always appear as
"uninitialized".
- Fixed bug #468: Property_get on $GLOBALS works only at top-level, by
adding GLOBALS to the super globals context.
- Fixed bug #453: Memory leaks.
- Fixed bug #445: error_prepend_string and error_append_string are ignored
by xdebug_error_cb. (Patch by Kent Davidson <kent@marketruler.com>)
- Fixed bug #442: configure: error: "you have strange libedit".
- Fixed bug #439: Xdebug crash in xdebug_header_handler.
- Fixed bug #423: Conflicts with funcall.
- Fixed bug #419: Make use of P_tmpdir if defined instead of hard coded
'/tmp'.
- Fixed bug #417: Response of context_get may lack page and pagesize
attributes.
- Fixed bug #411: Class/function breakpoint setting does not follow the
specs.
- Fixed bug #393: eval returns array data at the previous page request.
- Fixed bug #391: Xdebug doesn't stop executing script on catchable fatal
errors.
- Fixed bug #389: Destructors called on fatal error.
- Fixed bug #368: Xdebug's debugger bails out on a parse error with the
eval command.
- Fixed bug #356: Temporary breakpoints persist.
- Fixed bug #355: Function numbers in trace files weren't unique.
- Fixed bug #340: Segfault while throwing an Exception.
- Fixed bug #328: Private properties are incorrectly enumerated in case of
extended classes.
- Fixed bug #249: Xdebug's error handler messes up with the SOAP
extension's error handler.

+ DBGP:
- Fixed cases where private properties where shown for objects, but not
accessible.
- Added a patch by Lucas Nealan (lucas@php.net) and Brian Shire
(shire@php.net) of Facebook to allow connections to the initiating
request's IP address for remote debugging.
- Added the -p argument to the eval command as well, pending inclusion into
DBGP.
- Added the retrieval of a file's execution lines. I added a new
un-official method called xcmd_get_executable_lines which requires the
stack depth as argument (-d). You can only fetch this information for
stack frames as it needs an available op-array which is only available
when a function is executed.
- Added a fake "CLASSNAME" property to objects that are returned in debug
requests to facilitate deficiencies in IDEs that fail to show the "classname"
XML attribute.
