PHP Bug Type: Output Control
Bug description: implicit_flush not used in CLI, ob controlled by output_buffering
Description:
------------
In CLI implicit_flush is default to 1, however when using the reproducing
code implicit_flush is not used but the value of output_buffering is taken
into account. If output_buffering is 0 in php.ini then everything is fine
but if in php.ini the value is 4096 (or probably some value that is > 0)
the output is buffered no matter it's in CLI mode. Evenmore, flush()-ing
also has no effect as can be seen in the actual output.
This behaviour exists both in PHP_4_3 and in HEAD.
Reproduce code:
---------------
php -r 'echo
printf("phpversion=%s\noutput_buffering=%s\nimplicit_flush=%s\n",
phpversion(),ini_get("output_buffering"),
ini_get("implicit_flush"));flush();$a="fubar\n"; echo $a; fubar_func();'
Expected result:
----------------
As can be seen on execution 1 and 2 of the actual result PHP dies after a
fatal error of calling undefined function and after that the output which
is output before the call is feed to the console.
Execution 3 and 4 show the behaviour which is expected to be normal but is
only valid when output_buffering is 0 (implicit_flush as it can be seen is
not taken into account).
Actual result:
--------------
Exection 1:
PHP Fatal error: Call to undefined function fubar_func() in Command line
code on line 1
phpversion=5.0.0RC1-dev
output_buffering=4096
implicit_flush=1

Execution 2:
phpversion=5.0.0RC1-dev
output_buffering=0
implicit_flush=1
fubar

output_buffering=4096
implicit_flush=1
fubar
Execution 4:

implicit_flush=1
fubar
PHP Fatal error: Call to undefined function: fubar_func() in Command
