No warning / error on chdir failure

[KES777]

When chdir to not existent dir I get wrong error message in log file:

chdir      = /home/kes/work/www/mojo/test/myapp

[uWSGI] getting INI configuration from /usr/share/uwsgi/conf/default.ini

open("./logfile_plugin.so"): No such file or directory [core/utils.c line 3696]

If I correct to chdir = /home/kes/work/www/mojo/test/my_app uwsgi starts up OK.

@KES777 exact uwsgi build you are using?

for this test.ini

[uwsgi]
plugins             = logfile
chdir               = /nonexistent

on uWSGI 2.1-dev-717bf5a I get:

chdir() to /nonexistent
chdir(): No such file or directory [core/uwsgi.c line 2682]

[KES777]

uwsgi --version 2.1-dev-095c750

@KES777 are you sure you don't have the error on the very next line of what you pasted?

[KES777]

Yes. I am sure.

I bumped on the same error message and problem here. Once I fixed the chdir everything started working smoothly.

I was running uwsgi using uwsgi --ini testing.ini to check if everything was ok with my config file and project.

This is the error I was getting:

Starting uWSGI 2.0.7-debian (64bit) on [Fri May 13 10:35:39 2016] compiled with version: 5.2.1 20150903 on 08 September 2015 19:33:31 os: Linux-4.2.0-36-generic #41-Ubuntu SMP Mon Apr 18 15:49:10 UTC 2016 nodename: jayme-MacBookPro machine: x86_64 clock source: unix pcre jit disabled detected number of CPU cores: 4 current working directory: /home/jayme/projetos/testing/install/uwsgi detected binary path: /usr/bin/uwsgi-core chdir(): No such file or directory [core/uwsgi.c line 2537]

And this is everything running fine after I corrected the chdir:

logger = file:/var/log/uwsgi/app/testing.log

Thank you!

[unbit]

@kalkehcoisa sorry i do not get your report, the wrong configuration correctly reports a non-existent directory

[kalkehcoisa]

Yes, it says. But doesn't say what file is missing. The only reference to a file is "[core/uwsgi.c line 2537]". The problem is that the file has references to many other files, I got lost trying to discover which one was wrong and lost a lot of time. Even checked if core/uwsgi.c exists. Yeah... I know it makes absolutely no sense to point a line of a non-existent file... But I'm no expert in uwsgi, so I checked even the dumbest possibilities.

Anyway, thanks!
