[xdebug-general] Feature request: implement a path-rewrite system

Hi list,

I'd like to submit a feature request.

At our office, we keep all of our code on a centralized server. This means
that we generally edit our files over some sort of network filesystem, like
SMB, NFS or AFP. A side-effect of this is that any xdebug GUI client is
unable to correctly set breakpoints.

Imagine server A, where I have a file debug.php in
/home/mathieu/public_html/svnreps/project/ . When I access this file from my
workstation, the local path I access it over is
/Volumes/mathieu/public_html/svnreps/project/debug.php. If I use, say,
MacGDBp or Netbeans, to debug this file while it's running through the
webserver on Server A and try to set a breakpoint on line 15 of debug.php
GUI clients will tell xdebug to set a breakpoint on file

Net result: the breakpoint is never hit because the path given is not a file
that xdebug on Server A will ever encounter (/Volumes/mathieu as such
doesn't exist on Server A).

I had encountered this before when I built XDC
http://code.google.com/p/xdebugclient ) and XDC counters this problem by
offering the user a way to rewrite a local path to the remote path
automatically. But I think it would make sense to implement such a
path-rewrite system into Xdebug itself, so that any client can benefit from
it directly. Such a path-rewrite system could take the form of two
(.htaccess-configurable) settings:

php_value xdebug.path_rewrite_from "/Volumes/mathieu:/Volumes/michiel"
php_value xdebug.path_rewrite_to "/home/mathieu:/home/michiel"

This definition would define 2 rewrite rules:

- /Volumes/mathieu -> /home/mathieu
- /Volumes/michiel -> /home/michiel

Xdebug would apply these simple rewrite rules to any path it receives from a
client like breakpoints, source requests, etc before actually using the
given path. I suppose you could extend this into allowing regex for complex
rewrite rules, but I think that simple rewrite rules would cover most cases.


Kind regards,

Mathieu Kooiman
