Database load error

[rcarsey1]

I updated my installation yesterday and again today (the usual command found in the README). I am getting some errors in the browser. I also tried deleting /usr/local/share/tar1090 completely and re-downloading everything. No help.

I am seeing these errors in my Chrome dev mode console:

a6cb48: Database load error: parsererror at URL: db-a728e0e/A.js planeObject_a188fb0_a728e0e.js:2002 a02c40: Database load error: parsererror at URL: db-a728e0e/A.js planeObject_a188fb0_a728e0e.js:2002

I believe this is somehow related to the "precompress database files in tar1090-db" commit from 4 days ago. I think maybe I somehow caught things in the middle of switching over to using pre-compressed tar1090-db files.

gunzip-ing all the files in /db-a728e0e will fix the issue of course.

Yeah somehow your lighttpd isn't adding the Content-Encoding header properly.

Can you first try this fix:
https://github.com/wiedehopf/tar1090#history-not-loading-issue-possible-fix
(and after the possible fix rerun the tar1090 install script)

[wiedehopf]

Tempted to revert that change lighttpd .... just too unreliable maybe.

[rcarsey1]

I understand the issue now. I MAY be a unique situation, as I'm using nginx, not lighttpd. (I don't know what is native/defaults are in lighttpd vs nginx vs apache, etc). I will have to tweak my web server's configs. I will absolutely agree though that A) there is a lot of savings in compressing these, B) re-compressing these repeatedly via the web server is wasted compute time.

The install script produces a custom nginx conf file for each instance.

[wiedehopf]

To configure nginx for tar1090, please add the following line(s) in the server {} section:

include /usr/local/share/tar1090/nginx-tar1090-webroot.conf;
include /usr/local/share/tar1090/nginx-tar1090.conf;

does yours not output this?

[rcarsey1]

Yes, it outputted only the line:
include /usr/local/share/tar1090/nginx-tar1090.conf;

I was running on a self-compiled nginx v1.19.2 (i needed to compile some nginx modules for another project). I checked my old config files (ie. nginx.conf.rpmsave) and I do see it there.

I uninstalled nginx and installed the CentOS 8 native nginx (v1.14.1). Fresh config. Added the include line.

Everything works as intended.

Possible compatibility problem with nginx v1.19.. but its more probable that I didn't compile in some module needed.

Lets chalk this up to user-error.

[wiedehopf]

I don't think it's the nginx version.
You need to restart nginx when the configuration file for tar1090 changes (doesn't happen too often).

For lighttpd i restart it in the install script but i expect people using nginx to do it themselves ;)
Maybe i should print something extra in that regard.
