From: nicolas dot grekas+php at gmail dot com Operating system: Ubuntu PHP version: 7.2.0RC6 Package: Scripting Engine problem Bug Type: Bug Bug description:"stream_copy_to_stream" doesn't stream anymore Description: ------------ See test script. This behavior change has been introduced in PHP7.2RC6, and can be fixed by the change on 710 of main/streams/streams.c: ``` - if (!stream->wrapper || stream->wrapper->is_url) { + if (stream->wrapper != &php_plain_files_wrapper) { ``` Test script: --------------- run on the shell: php -r 'echo "ping"; stream_copy_to_stream(STDIN, STDOUT);' then type something to populate stdin, and hit "enter". On "enter", the input should be copied to the STDOUT. But on RC6, this doesn't happen until STDIN is closed.
