- xdebug.collect_params is no longer a boolean setting. Although it worked fine, phpinfo() showed only just On or Off here.
- Fixed the Xdebug version of raw_url_encode to not encode : and \. This is not necessary according to the RFCs and it makes debug breakpoints work on Windows.

- script name
- %t
- timestamp (seconds)
- %u
- timestamp (microseconds)
- %H

Removed functions
- Removed support for Memory profiling as that didn't work properly.
- Get rid of xdebug.default_enable setting and associated functions: xdebug_disable() and xdebug_enable().
Added features
- Implemented support for four different xdebug.collect_params settings for stack traces and function traces.
- Allow to trigger profiling by the XDEBUG_PROFILE cookie.
DBGP
- Correctly add namespace definitions to XML.
- Added the xdebug namespace that adds extra information to breakpoints if available.
- Stopped the use of
elements for exception breakpoints, as that violates the protocol. - [2007-01-31] — Xdebug 2.0.0RC3
Changes
- Removed the bogus "xdebug.allowed_clients" setting - it was not implemented.
- Optimized used variable collection by switching to a linked list instead of a hash. This is about 30% faster, but it needed a quick conversion to hash in the case the information had to be shown to remove duplicate variable names.
Fixed bugs
- Fixed bug #232: PHP log_errors functionality lost after enabling xdebug error handler when CLI is used.
- Fixed problems with opening files - the filename could cause double free issues.
- Fixed memory tracking as memory_limit is always enabled in PHP 5.2.1 and later.
- Fixed a segfault that occurred when creating printable stack traces and collect_params was turned off.
- [2006-12-24] — Xdebug 2.0.0RC2
Added new features
- Implemented the "xdebug.var_display_max_children" setting. The default is set to 128 children.
- Added types to fancy var dumping function.
- Implemented FR #210: Add a way to stop the debug session without having to execute a script. The GET/POST parameter "XDEBUG_SESSION_STOP_NO_EXEC" works in the same way as XDEBUG_SESSION_STOP, except that the script will not be executed.
- DBGP: Allow postmortem analysis.
- DBGP: Added the non-standard function xcmd_profiler_name_get.
Changes
- Fixed the issue where xdebug_get_declared_vars() did not know about variables there are in the declared function header, but were not used in the code. Due to this change expected arguments that were not send to a function will now show up as ??? in stack and function traces in PHP 5.1 and PHP 5.2.
- Allow xdebug.var_display_max_data and xdebug.var_display_max_depth settings of -1 which will unlimit those settings.
- DBGP: Sort super globals in Globals overview.
- DBGP: Fixed a bug where error messages where not added upon errors in the protocol.
- DBGP: Change context 1 from globals (superglobals + vars in bottom most stack frame) to just superglobals.
Fixed bugs
- Fixed linking error on AIX by adding libm.
- Fixed dead code analysis for THROW.
- Fixed oparray prefill caching for code coverage.
- Fixed the xdebug.remote_log feature work.
- DBGP: Fixed a bug where $this did not appear in the local scoped context.
- DBGP: Reimplemented property_set to use the same symbol fetching function as property_get. We now only use eval in case no type (-t) argument was given.
- DBGP: Fixed some issues with finding out the classname, which is important for fetching private properties.
- DBGP: Fixed usage of uninitialized memory that prevented looking up numerical array keys while fetching array elements not work properly.
- Fixed bug #228: Binary safety for stream output and property fetches.
- Fixed bug #227: The SESSION super global does not show up in the Globals scope.
- Fixed bug #225: xdebug dumps core when protocol is GDB.
- Fixed bug #224: Compile failure on Solaris.
- Fixed bug #219: Memory usage delta in traces don't work on PHP 5.2.0.
- Fixed bug #215: Cannot retrieve nested arrays when the array key is a numeric index.
- Fixed bug #214: The depth level of arrays was incorrectly checked so it would show the first page of a level too deep as well.
- Fixed bug #213: Dead code analysis doesn't take catches for throws into account.
- Fixed bug #211: When starting a new session with a different idekey, the cookie is not updated.
- Fixed bug #209: Additional remote debugging session started when triggering shutdown function.
- Fixed bug #208: Socket connection attempted when XDEBUG_SESSION_STOP.
- Fixed PECL bug #8989: Compile error with PHP 5 and GCC 2.95.
- [2006-10-08] — Xdebug 2.0.0RC1
Added new features
- Implemented FR #70: Provide optional depth on xdebug_call_* functions.
- Partially implemented FR #50: Resource limiting for variable display. By default only two levels of nested variables and max string lengths of 512 are shown. This can be changed by setting the ini settings xdebug.var_display_max_depth and xdebug.var_display_max_data.
- Implemented breakpoints for different types of PHP errors. You can now set an 'exception' breakpoint on "Fatal error", "Warning", "Notice" etc. This is related to bug #187.
- Added the xdebug_print_function_trace() function to display a stack trace on demand.
- Reintroduce HTML tracing by adding a new tracing option "XDEBUG_TRACE_HTML" (4).
- Made xdebug_stop_trace() return the trace file name, so that the following works: <?php echo file_get_contents( xdebug_stop_trace() ); ?>
- Added the xdebug.collect_vars setting to tell Xdebug to collect information about which variables are used in a scope. Now you don't need to show variables with xdebug.show_local_vars anymore for xdebug_get_declared_vars() to work.
- Make the filename parameter to the xdebug_start_trace() function optional. If left empty it will use the same algorithm to pick a filename as when you are using the xdebug.auto_trace setting.
Changes
- Implemented dead code analysis during code coverage for: abstract methods, dead code after return, throw and exit, and implicit returns when a normal return is present.
- Improved readability of stack traces.
- Use PG(html_errors) instead of checking whether we run with CLI when deciding when to use HTML messages or plain text messages.
Fixed bugs
- Fixed bug #203: PHP errors with HTML content processed incorrectly. This patch backs out the change that was made to fix bug #182.
- Fixed bug #198: Segfault when trying to use a non-existing debug handler.
- Fixed bug #197: Race condition fixes created too many files.
- Fixed bug #196: Profile timing on Windows does not work.

- Implemented FR #124: Add backtrace dumping information when exception thrown.
- Implemented FR #70: Add feature_get breakpoint_types.
- Added profiling aggregation functions (patch by Andrei Zmievski)
- Implemented the "timestamp" option for the xdebug.trace_output_name and xdebug.profiler_output_name settings.
- Added the xdebug.remote_log setting that allows you to log debugger communication to a log file for debugging. This can also be set through the "remote_log" element in the XDEBUG_CONFIG environment variable.
- Added a "script" value to the profiler_output_name option. This will write the profiler output to a filename that consists of the script's full path (using underscores). ie: /var/www/index.php becomes var_www_index_php_cachegrind.out. (Patch by Brian Shire).
- DBGp: Implemented support for hit conditions for breakpoints.
- DBGp: Added support for conditions for file/line breakpoints.
- DBGp: Added support for hit value checking to file/line breakpoints.
- DBGp: Added support for "exception" breakpoints.
Performance improvements
- Added a cache that prevents the code coverage functionality from running a "which code is executable check" on every function call, even if they were executed multiple times. This should speed up code coverage a lot.
- Speedup Xdebug but only gathering information about variables in scopes when either remote debugging is used, or show_local_vars is enabled.

Added new functions
- xdebug_debug_zval() to debug zvals by printing its refcounts and is_ref values.
Changed features
- xdebug_code_coverage_stop() will now clean up the code coverage array, unless you specify FALSE as parameter.
- The proper Xdebug type is "hash" for associative arrays.
- Extended the code-coverage functionality by returning lines with executable code on them, but where not executed with a count value of -1.
Fixed bugs
- DBGP: Make property_get and property_value finally work as they should, including retrieving information from different depths then the most top stack frame.
- DBGP: Fix eval'ed $varnames in property_get.
- DBGP: Support the -d option for property_get.
- Fixed the exit handler hook to use the new "5.1" way of handling it; which fortunately also works with PHP 5.0.
- Fixed bug #102: Problems with configure for automake 1.8.
- Fixed bug #101: crash with set_exeception_handler() and uncatched exceptions.
- Fixed bug #99: unset variables return the name as a string with property_get.

- [2004-09-15]
Added new features
- Added support for the new DBGp protocol for communicating with the debug engine.
- A computerized trace format for easier parsing by external programs.
- The ability to set remote debugging features via the environment. This allows an IDE to emulate CGI and still pass the configuration through to the debugger. In CGI mode, PHP does not allow -d arguments.
- Reimplementation of the tracing code, you can now only trace to file; this greatly enhances performance as no string representation of variables need to be kept in memory any more.
- Re-implemented profiling support. Xdebug outputs information the same way that cachegrind does so it is possible to use Kcachegrind as front-end.
- Xdebug emits warnings when it was not loaded as a Zend extension.
- Added showing private, protected and public to the fancy var_dump() replacement function.
- Added the setting of the TCP_NODELAY socket option to stop delays in transferring data to the remote debugger client. (Patch by Christof J. Reetz)
- DebugClient: Added setting for port to listen on and implemented running the previous command when pressing just enter.
Added new functions
- xdebug_get_stack_depth() to return the current stack depth level.
- xdebug_get_tracefile_name() to retrieve the name of the tracefile. This is useful in case auto trace is enabled and you want to clean the trace file.
- xdebug_peak_memory_usage() which returns the peak memory used in a script. (Only works when --enable-memory-limit was enabled)
Added feature requests
- FR #5: xdebug_break() function which interupts the script for the debug engine.
- FR #30: Dump current scope information in stack traces on error.
- FR #88: Make the url parameter XDEBUG_SESSION_START optional. So it can be disabled and the user does not need to add it.
Added new php.ini settings
- xdebug.auto_trace_file: to configure a trace file to write to as addition to the xdebug.auto_trace setting which just turns on tracing.
- xdebug.collect_includes: separates collecting names of include files from the xdebug.collect_params setting.
- xdebug.collect_return: showing return values in traces.
- xdebug.dump_global: with which you can turn off dumping of super globals even in you have that configured.
- xdebug.extended_info: turns off the generation of extended opcodes that are needed for stepping and breakpoints for the remote debugger. This is useful incase you want to profile memory usage as the generation of this extended info increases memory usage of oparrrays by about 33%.
- xdebug.profiler_output_dir: profiler output directory.
- xdebug.profiler_enable: enable the profiler.
- xdebug.show_local_vars: turn off the showing of local variables in the top most stack frame on errors.
- xdebug.show_mem_delta: show differences between current and previous memory usage on a function call level.
- xdebug.trace_options: to configure extra options for trace dumping: o XDEBUG_TRACE_APPEND option (1)
Changed features
- xdebug_start_trace() now returns the filename of the tracefile (.xt is added to the requested name).
- Changed default debugging protocol to dbgp instead of gdb.
- Changed default debugger port from 17869 to 9000.
- Changed trace file naming: xdebug.trace_output_dir is now used to configure a directory to dump automatic traces; the trace file name now also includes the pid (xdebug.trace_output_name=pid) or a crc32 checksum of the current working dir (xdebug.trace_output_name=crc32) and traces are not being appended to an existing file anymore, but simply overwritten.
- Removed $this and $GLOBALS from showing variables in the local scope.
Removed functions
- xdebug_get_function_trace/xdebug_dump_function_trace() because of the new idea of tracing.

- Fixed bug #53: Feature get misusing the supported attribute.
- Fixed bug #51: Only start a debug session if XDEBUG_SESSION_START is passed as GET or POST parameter, or the DBGP_COOKIE is send to the server. Passing XDEBUG_SESSION_STOP as GET/POST parameter will end the debug session and removes the cookie again. The cookie is also passed to the remote handler backends; for DBGp it is added to the
packet. - Fixed bug #49: Included file's names should not be stored by address.
- Fixed bug #44: Script time-outs should be disabled when debugging.
- Fixed bug #36: GDB handler using print causes segfault with wrong syntax

- Fixed bug #2: "pear package" triggers a segfault.
- Fixed crash bug when a function had sprintf style parameters (ie. strftime()).
- [2003-07-16]
- Added "id" attribute to <var /> elements in responses from the remove debugger when the response method is XML. This makes it possible to distinguish between unique elements by use of recursion for example.
