Summary0001269: xdebug_break() does not work in PHP Interactive Shell

Any attempt to run xdebug_break() will be ignored when running with

php -a -d xdebug.idkey=atom

Even, "include 'file.php'" fails to trigger a break with xdebug_break();

Steps To Reproduce
  1. Make a file with xdebug_break(); and name it file.php
  2. run "php -a -d xdebug.idkey=atom"
  3. Listen for breakpoints.
  4. run "include 'file.php'"

The code will not break.

TagsNo tags attached.

PHP Version8.0-dev

Have you exported the environment variable XDEBUG_CONFIG on the shell?

If I run it like this:

XDEBUG_CONFIG="idekey=dr" php -a -d xdebug.remote_enable=1

Then it connects to the debugger, and stops at the xdebug_break() just fine.

I could be missing something but I just tried (using 'debugclient' that comes with the extension) and it doesn't seem to be working :/

After including PHP file the client receives INIT package like this:

<init xmlns="urn:debugger_protocol_v1" xmlns:xdebug="; fileuri="file:///home/pc/test_dir/test.php" language="PHP" xdebug:language_version="5.5.9-1ubuntu4.14" protocol_version="1.0" appid="16880" idekey="dr"><engine version="2.4.0RC5-dev"><![CDATA[Xdebug]]></engine><author><![CDATA[Derick Rethans]]></author><url><![CDATA[]]>&lt;/url>&lt;copyright>&lt;![CDATA[Copyright (c) 2002-2016 by Derick Rethans]]></copyright></init>

This is great, but then after: 'run -i 1' the PHP script executes completely without breaking and 'debugclient' prompt stays busy. Only after I quit PHP the client prompt returns with a package like this:

<response xmlns="urn:debugger_protocol_v1" xmlns:xdebug="; command="run" transaction_id="1" status="stopping" reason="ok"></response>


I tried the same PHP script in non-interactive mode it works as expected.
INIT package is received and then after: 'run -i 1' I get:

<response xmlns="urn:debugger_protocol_v1" xmlns:xdebug="; command="run" transaction_id="1" status="break" reason="ok"><xdebug:message filename="file:///home/pc/test_dir/test.php" lineno="8"></xdebug:message></response>


Am I doing it wrong? Could it be PHP version? I'm on master branch of xdebug (commit: f4c6c8c).

I've spend some more time figuring out what the problem is. I can indeed reproduce this now.

xdebug_break() works by setting a flag (XG(context).do_break) to 1, which then
gets seen once the statement is finished. Only then does it interupt.

For some reason, the intermediate
statement interceptors are not being generated by PHP, even though I have set
CG(compiler_options) |= ZEND_COMPILE_EXTENDED_INFO.

Even when forcing that with the additional -e argument to PHP, this does not
seem to make PHP fire the inter-statement hooks (xdebug_statement_call), and
hence xdebug_break() can't be intercepted.

I will have to suspend this until the appropriate steps can be taken in PHP

In Php > 8, it works, but only once at debugger session. In Xdebug 3.3.0 it activates by whatever command is executed first, and also only once per session.

I meant once per PHP interactive shell session

@anton.m4354 -- that would make sense, as that is when Xdebug would initiate the debugging connection
