[EMAIL PROTECTED]: The problem is that this bug affects Debian's PHP5 package of etch[1] and in order to fix it the right patch is required. We can't simply 'update' the source package.

What this patch does is just remove one extra memory pointer which was not needed. Correct fix would be to use O_NONBLOCK when opening file descriptor and then test for EAGAIN. Or use select(2) before reading from descriptor in safe_read() function to test if data is available for reading. I could be wrong, but it just doesn't seems to be fix for this problem. ------------------------------------------------------------------------ [2007-02-16 11:48:12] [EMAIL PROTECTED] I hope the bug is fixed in CVS HEAD, PHP_5_2 (not in 5.2.1) and PHP_4_4 (not in 4.4.5). The patch for PHP_5_2 folows: Index: sapi/cgi/cgi_main.c =================================================================== RCS file: /repository/php-src/sapi/cgi/cgi_main.c,v retrieving revision 1.267.2.15.2.22 diff -u -p -d -r1.267.2.15.2.22 cgi_main.c --- sapi/cgi/cgi_main.c 15 Feb 2007 12:33:16 -0000 1.267.2.15.2.22 +++ sapi/cgi/cgi_main.c 16 Feb 2007 11:16:39 -0000 @@ -355,18 +355,14 @@ static int sapi_cgi_send_headers(sapi_he static int sapi_cgi_read_post(char *buffer, uint count_bytes TSRMLS_DC) { - uint read_bytes=0, tmp_read_bytes; -#if PHP_FASTCGI - char *pos = buffer; -#endif + int read_bytes=0, tmp_read_bytes; count_bytes = MIN(count_bytes, (uint) SG(request_info).content_length - SG(read_post_bytes)); while (read_bytes < count_bytes) { #if PHP_FASTCGI if (fcgi_is_fastcgi()) { fcgi_request *request = (fcgi_request*) SG(server_context); - tmp_read_bytes = fcgi_read(request, pos, count_bytes - read_bytes); - pos += tmp_read_bytes; + tmp_read_bytes = fcgi_read(request, buffer + read_bytes, count_bytes - read_bytes); } else { tmp_read_bytes = read(0, buffer + read_bytes, count_bytes - read_bytes); } ------------------------------------------------------------------------ [2007-01-31 11:56:49] gabriel at oxeva dot fr And today, I can now confirm that the bugs exists with PHP 5.2.0 too.
