Enhance export #19

Closed nilmerg closed 4 years ago

nilmerg commented 4 years ago

fixes #17

cristorrian commented 4 years ago

Thanks @nilmerg for the fix. :+1: With this fix and the patch of @durzo the pdfexport module work properly. But the pdf file sent trought job schedule of reporting module is sent without red and green bubbles. I think that this issue is related with the reporting module.

I have posted this issue here: https://github.com/Icinga/icingaweb2-module-reporting/issues/47

It works nice w/ php7.3, but in php7.4 it still hangs and you'll get this in the browser window:

Empty read; connection dead? Stream state: {"timed_out":false,"blocked":true,"eof":true,"stream_type":"tcp_socket\/ssl","mode":"r+","unread_bytes":0,"seekable":false}

and this (from the icingaweb2.log):

@netphantm Could you please run the following manually on the host with PHP 7.4?

HOME=/tmp /usr/local/bin/google-chrome --bwsi --headless --disable-gpu --no-sandbox --no-first-run --disable-dev-shm-usage --remote-debugging-port=0 --homedir=/tmp --user-data-dir=/tmp

or turn on DEBUG logging for icingaweb2.

Either way, the actual output of the browser should be visible. Please include that in your reply.

I omitted this info, sorry: I use chromium-browser, since it's on an armhf odroid device. hmm, I had to try it a few times, since it suddenly worked sometimes, until it didn't and here it is:

Hmmm, okay. Though this is different than what you initially posted. Please report back (again with the browser's output) in case the error is this: Terminated browser process after 10 seconds elapsed without the expected output

While the log you just posted is of course valuable it doesn't explain the error above.

netphantm commented 4 years ago

hm, I cannot get it to throw the same error again, it's this last one again and again (Empty read; connection dead?), and sometimes it just works. I ran what you posted tho, perhaps this helps:

and there it hangs.

Yes this might be of help. Thanks!

netphantm commented 4 years ago

I noticed that on very rare occasions, it works even with php-7.4 on this system (Ubuntu 18.04.4 LTS, 4.14.150-170 armv7l, chromium). On the company server (debian 10, 4.19.0-6-amd64 with php-7.3 and chrome) it works almost all the times (one user reported an error tho). If I encounter another error, I will post it here.
