php-java-bridge-users Mailing List for PHP/Java Bridge

Hi,

PHP/Java Bridge 5.6 will contain a new PHP source level debugger.

It is a pure PHP implementation centered around Linus MacCabe's idea to use
the official PHP token API to add breakpoints to a PHP script at run-time.

You can add debug capabilities to a PHP script simply by include("pdb.php")
or via http://.../pdb.php?script=... The JavaBridge.war will contain two new
config settings: debugger-host and debugger-port. If a client listens on
this port during bridge startup, the client can be used for remote
debugging.

It will use the Zend Debugger protocol, as published on eclipse.org. It will
be compatible with the Zend Debugger and is used by Eclipse as well as other
products (aptana studio uses the same protocol).

My plan is to implement the following 11 Responses first so that we can test
the debugger in a PHP eclipse environment.

1 MSG_START, recv
1001 MSG_START_R, send

12 MSG_STEP_OVER, recv
1012 MSG_STEP_OVER_R, send

14 MSG_GO, recv
1014 MSG_GO_R, send

21 MSG_ADD_BREAKPOINT, recv
1021 MSG_ADD_BREAKPOINT_R, send

32 MSG_GET_VAR, recv
1032 MSG_GET_VAR_R, send

34 MSG_GET_CALL_STACK, recv
1034 MSG_GET_CALL_STACK_R, send

10000 MSG_SET_PROTOCOL, recv
11000 MSG_SET_PROTOCOL_R, send

36 GetCWDRequest, recv
1036 GetCWDResponse, send

2003 MSG_READY, send
2005 MSG_SESS_START, send
2009 StartProcessFileNotification, send

2010 ContinueProcessFileNotification, recv

10001 FileContentRequest, send
10002 FileContentExtendedRequest, send
11001 FileContentResponse, recv

I will set up a new web site at http://php-java-bridge/pdb  The binaries can
be downloaded from there. -- I think I can make a first release next month.

Hi,

I think the xdebug C code is more a problem than anything else.

There's a pure PHP debugger ("gubed") which uses the official PHP-level API
(*token_get_all, ...) to attach the debugger to your PHP script.

The advantage of this method is that it is pure PHP code and therefore
cannot crash your PHP installation. And it will work with future versions of
PHP.
