Summary0000327: xdebug.var_displaymax* values are ignored in remote usage
Description

running xdebug for remote debugging, however it seems that the xdebug.var_display_max_children, xdebug.var_display_max_data, xdebug.var_display_max_depth settings in php.ini are ignored and internal default values are used. Note that these internal values used are different from the normal defaults

xdebug.var_display_max_data:
normal default: 512
php.ini setting: 2048
queried value: 1024

xdebug.var_display_max_children
normal default: 128
php.ini setting: 2048
returned value: 32

xdebug.var_display_max_depth
normal default: 3
php.ini setting: 20
returned value: 1

workaround:
when debugging session launches send these DBGp commands to reset the configurations to the desired values:

feature_set -i 1 -n max_children -v <value>
feature_set -i 2 -n max_data -v <value>
feature_set -i 3 -n max_depth -v <value>

Additional Information

php.ini:
xdebug.var_display_max_children 2048
xdebug.var_display_max_data 2048
xdebug.var_display_max_depth 20

phpinfo() output:
xdebug.var_display_max_children 2048 128
xdebug.var_display_max_data 2048 512
xdebug.var_display_max_depth 20 3

This is not a bug, those three settings are not supposed to work on remote debugging. The defaults need to be different as it is a bad idea to have a depth != 1 for remote debugging, while it also cumbersome to deal with var_dump() displays if the depth = 1 there. I updated the documentation for those 3 settings to make this a bit clearer.
