Logging the wt_config.xml

Added by Sebastian Fett almost 3 years ago

I currently run my software on 2 different systems, both have an identical wt_config.xml yet on one system it fires "fileTooLarge()" while on the other it doesnt while using identical files. Is there a way to show which config file the application loaded? Do I break the library by copy and pasting it form one system to another? (Especially considering the config)

Regards

When Wt starts up, you should get a log line similar to this:

[2020-Feb-10 10:11:35.799] 30247 - [info] "config: reading Wt config file: approot/wt_config.xml

That should indicate which wt_config.xml was loaded. With wthttp can always specify it exactly with the -c or --config option.

Copying the library shouldn't necessary break it as long as the OS isn't too different.

Thanks Ill recheck, everything is working exactly the same except for one firing the "fileTooLarge()" while the other one uploads the file.

I am working with geometries on my server so uploads in the Gigabytes are quite common, so I needed to change that in the config and copy pasting the config apparently doesnt work for me.

Okay I rechecked, on system says

[2020-Feb-10 10:26:17.677] 26905 - [info] "config: reading Wt config file: /p/tv/local/redhat/wt-4.1.0-libs/etc/wt/wt_config.xml (location = './test.wt')"                                                        
[2020-Feb-10 10:26:17.678] 26905 - [info] "WServer/wthttp: initializing built-in wthttpd"                                                                                                                         
[2020-Feb-10 10:26:17.678] 26905 - [info] "wthttp: started server: http://0.0.0.0:8080" 

the other one exactly the same but without the config line, so only the last 2 lines and thats the one failing the upload. So I found the problem but I have no idea how to progress except for installing the library again.

Interesting that the reading Wt config file line gets eaten. Are you logging to std::cerr (the default), or do you have it configured to log to a file? What if you tried to explicitly specify the location of your wt_config.xml?

RE: Logging the wt_config.xml - Added by Sebastian Fett almost 3 years ago

Yes I am using the standard error, no piping to a file and there is nothing on the console. What would be the environment variable I need to set to explicitly to specify the config location?

RE: Logging the wt_config.xml - Added by Roel Standaert almost 3 years ago

Are you using wthttp or wtfcgi?

With wthttp it should just be the --config command line option.

In general (for both wthttp and wtfcgi) it should also look at the WT_CONFIG_XML environment variable.

http, ---config worked perfectly. Thanks a lot. Ran into another issue but Ill make a separate post about it.
