Summary: php -b 127.0.0.1 vs php -y php-fpm.conf -x
Status: Closed
Type: Bug
Package: FPM related
Operating System: ubuntu 9.04
PHP Version: 5.2.13

New Comment:
To whomever maintains those code, i really recommond them to specify
much more exact, accurate, detailed information for this 'bug', thanks.
Finally i found out the why, tsrm_virtual_cwd.c :
....................
if (use_realpath != CWD_EXPAND) {
#if !defined(TSRM_WIN32) && !defined(NETWARE)
char resolved_path[MAXPATHLEN];
if (!realpath(path, resolved_path)) { /* Note: Not threadsafe on older
*BSD's */
perror("realpath error:");
if (use_realpath == CWD_REALPATH) {
printf("=====================%d\n", __LINE__);
return 1;
}
goto no_realpath;
}
..........................
perror outputs Permission denied, so why don't u enlarge this
information somewhere in the error log, i mean to let the user have some
place to figure out, maybe it's comsumptive in production environment,
but u can enable it in a debug compile, and i know this block of code is
not FPM specific.
Maybe because i'm a newbie in this field, miraclely placed the webroot
in my home directory, which other users' process doesn't have permission
to go through, but i think 'No input file specified' is really too
short, too expert-speaking.......

FPM is not supported on 5.2.x and your revision is old as the conf file
is
formatted in XML (now it's INI).
Please use 5.3.x from http://snaps.php.net/
If you're using the FPM patch from http://php-fpm.org to use FPM on
5.2.x,
please ask on the FPM mailing list
(http://groups.google.com/group/highload-php-
en).

"As i tested, while started as the 1st way, this function return 0, and
the tsrm_realpath returns NULL'
This sentence was written wrong, correct is : the 1st way returns 0; the
second returns 1;

Description:
------------
As starting php-cgi in 2 ways, the 2 results were different.
1./path/to/php-cgi -b 127.0.0.1:9000
2./path/to/php-cgi -y /path/to/php-fpm.conf -x
The first one was correct.
The second, which said: 'No input file specified'.
As i tracked down the c code, i found out the reason finally, but dunno
why still.
/php/to/phpsrc/TSRM/tsrm_virtual_cwd.c
CWD_API int virutal_file_ex(cwd_state *state,.....)
around line 1339
the exact code block:
#if !defined(TSRM_WIN32) && !defined(NETWARE)
..........
if (use_realpath == CWD_REALPATH) {
return 1;
}
goto no_realpath;
It's the above function that keeps the problem presenting..
As i tested, while started as the 1st way, this function return 0, and
the tsrm_realpath returns NULL, also tsrm_realpath was called from
init_request_info. I think u must be familiarer with the code.
And the 2cd way was all right.
Here is my nginx(0.6.39) conf block:
server {
listen 80;
server_name pk.local.com;
index index.php;
root /home/zyk/pk_local;
location / {
root /home/zyk/pk_local;
fastcgi_pass 127.0.0.1:9000;
# fastcgi_pass
unix:/usr/local/app/php/logs/php.sock;
fastcgi_index index.php;
fastcgi_intercept_errors on;
include fcgi.conf;
include fastcgi_params.default;
}
}
}
Dir /home/zyk/pk_local is RW for the php daemon userid.
Here is my php configure option:
configure --enable-fastcgi --enable-fpm --enable-mbstring
--prefix=/usr/local/app/php

As i dunno if it's a bug yet, maybe it's configuration problem. But
there is really no easy way to solve this particular stuff.
Any suggestions?
Thanks in advance.
