PHP Bug Type: CGI related
Bug description: non-portable CGI code (Empty POST data)
Description:
------------
Using a generic web server with a simple CGI support (running on Windows
XP), I fail to obtain any $_POST data. However, raw post data are OK. Raw
post data is sent to the PHP-CGI.exe via redirected pipe handle. PHP-CGI
reads correctly posted raw data using stdin.
I suspect the culprit may be with the following PHP source code:
File:cgi_main.c
Routine:static int sapi_cgi_read_post(char *buffer, uint count_bytes
TSRMLS_DC)
...
tmp_read_bytes = read(0, buffer + read_bytes, count_bytes - read_bytes);
...
Low level i/o functions read,write,open are not 100% portable.
The code is most like meant to read stdin. Assuming that file descriptor
for stdin is numerically equal to 0 on all platforms is wrong.
The code should be probably something like this
tmp_read_bytes = read(_fileno(stdin), buffer + read_bytes, count_bytes -
read_bytes);
