Description

Hi,

I used WFileUpload with older releases of Wt (eg. 3.0.x and 3.1.x) and it was working perfectly. But now I tried 3.2.1, 3.2.3-rc1 and the git version and they are all having a strange problem.

I have 20480 in my wt_config.xml,

and client_max_body_size 100M; in nginx.conf.

When I upload a file less than 128K I got this log from my app:

I have access to the file on server side and the file content is just fine (even thought there is an error in the log).

When I upload a file larger than 128K my app prints out the file content to the log output, and then an error like the above one and uploaded() is not emitted (looks like it got canceled).

I believe I found the reason for this, this bug is related to wt_config.xml handling.

I have no /etc/wt/wt_config.xml, then I am giving the path to wt_config.xml when spawning my process like this.

$ cd {WWW_ROOT} && WT_CONFIG_XML={/PATH/TO/wt_config.xml} /usr/local/bin/spawn-fcgi -d {WWW_ROOT} -s {/PATH/TO/SOCKET} -n -M {PERMISSIONS} -u {WWW_USER} -g {WWW_GROUP} --- 4 &

As you can see it got picked up (at least log says so):

[2012-Oct-19 21:15:29.833880] 93042 - [info] "WServer/wtfcgi: initializing relay server"

[2012-Oct-19 21:15:29.836194] 93042 - [info] "config: reading Wt config file: /srv/samsungdforum.ir/lib/wt/etc/wt/wt_config.xml (location = '/srv/samsungdforum.ir/www/root.fcgi')"

[2012-Oct-19 21:15:29.838019] 93042 - [info] "wtfcgi: spawned session process: pid = 93043"

[2012-Oct-19 21:15:29.838526] 93042 - [info] "wtfcgi: reading FastCGI stream from stdin"

[2012-Oct-19 21:15:30.177850] 93043 - [info] "WServer/wtfcgi: initializing shared wtfcgi session process"

Then I made a copy of my config file to /etc/wt/ and tried to respawn the process:

[2012-Oct-19 21:07:06.389451] 91681 - [info] "WServer/wtfcgi: initializing relay server"

[2012-Oct-19 21:07:06.391857] 91681 - [info] "config: reading Wt config file: /srv/samsungdforum.ir/lib/wt/etc/wt/wt_config.xml (location = '/srv/samsungdforum.ir/www/root.fcgi')"

[2012-Oct-19 21:07:06.393727] 91681 - [info] "wtfcgi: spawned session process: pid = 91682"

[2012-Oct-19 21:07:06.394232] 91681 - [info] "wtfcgi: reading FastCGI stream from stdin"

[2012-Oct-19 21:07:06.740514] 91682 - [info] "config: reading Wt config file: /etc/wt/wt_config.xml (location = '/srv/samsungdforum.ir/www/root.fcgi')"

[2012-Oct-19 21:07:06.742545] 91682 - [info] "WServer/wtfcgi: initializing shared wtfcgi session process"

As you can see it picked up two config files; one in /srv/samsungdforum.ir/lib/wt/etc/wt/wt_config.xml and the last one in /etc/wt/wt_config.xml

Then my app and the WFileUpload works as expected.

According to http://www.webtoolkit.eu/wt/doc/reference/html/overview.html#fastcgi:

The following locations for the wt_config.xml configuration file are considered, in this order:

value of environment variable $WT_CONFIG_XML
within the app root, as configured by the environment variable $WT_APP_ROOT: $WT_APP_ROOT/wt_config.xml
the compile-time default (/etc/wt/wt_config.xml)

The strange thing is Wt ignores my configuration file on both scenario !?

Since it does make sense to have separate config files not a global one for separate Wt-Apps I believe this is a bug.
