#48260 [NEW]: Size of PHP file affects behaviour of virtual() or #include virtual
From: p dot tipper at lancaster dot ac dot uk
Operating system: Debian GNU/Linux 5.0.1
PHP version: 5.3CVS-2009-05-13 (snap)
PHP Bug Type: Apache2 related
Bug description: Size of PHP file affects behaviour of virtual() or #include virtual
Description:
------------
When doing an #include virtual of a php file this seems to change to an
include() call (and thus hit basedir restrictions) when the base PHP file
reaches a certain size. Also connected with this behaviour is sub-virtual
requests also stop working. This seems baffling as this behaviour should
occur purely in Apache. Use of virtual() seems to also trigger this bug.
Reproduce code:
---------------
This URL works normally:
http://red-velvet.lancs.ac.uk:8080/~tipper/include/base/index.php?amount=200
This URL demonstrates the bug:
http://red-velvet.lancs.ac.uk:8080/~tipper/include/base/index.php?amount=350
To see how this is affected by setting
open_basedir="/usr/local/lib/php:/tmp:." then check these URLs:
Working:
http://red-velvet.lancs.ac.uk:8080/~tipper/include/base/index.php?amount=200&basedir=1
Broken:
http://red-velvet.lancs.ac.uk:8080/~tipper/include/base/index.php?amount=350&basedir=1
The "?amount=N" adds more output lines to the main PHP file thus changing
its size in an easy manner.
All code available from
http://red-velvet.lancs.ac.uk:8080/~tipper/include/include-test.tar.gz
Expected result:
----------------
The #include virtual (or virtual()) data should continue to behave as
normal, and shouldn't fall foul of basedir restrictions. The following
block should always appear at the top of the output:
This is an included file /~tipper/include/subdir/test.php
Request was /~tipper/include/base/index.php?amount=200
This is an included file /~tipper/include/subdir/test2.php
Request was /~tipper/include/base/index.php?amount=200
End of included file /~tipper/include/subdir/test2.php
End of included file /~tipper/include/subdir/test.php
(Where 200 will be whatever number you set for amount= )
Actual result:
--------------
Once the amount goes above about 340 lines this seems to be the output
(from
http://red-velvet.lancs.ac.uk:8080/~tipper/include/base/index.php?amount=350
)
This is an included file /~tipper/include/base/index.php
Request was /~tipper/include/base/index.php?amount=350
End of included file /~tipper/include/base/index.php
If you try this with open_basedir set to "/usr/local/lib/php:/tmp:." you
get the following error (from
http://red-velvet.lancs.ac.uk:8080/~tipper/include/base/index.php?amount=350&basedir=1
)
