New Blynk Server Release

Dmitriy · September 30, 2017, 7:13pm

Ok. I created the ticket. Will take a look when I have free time. For now updating to 0.28.0 is not required as there were no changes on apps.

Jamin · September 30, 2017, 7:14pm

No rush as the previous version is running my projects fine.

psoro · September 30, 2017, 11:49pm

Mmm… Java 9… I Will try to update my Orange Pi, not sure about the proper procedure… … for sure a good challenge for me due to my lack of knowledge about Linux… Fingers crossed!

Gunner · October 1, 2017, 12:07am

Warning!! Linux No0b alert

Even after running sudo apt-get update then sudo apt-get install oracle-java9-jdk, I get this error:

gunner@AspireOne ~ $ sudo apt-get install oracle-java9-jdk

I am running Linux Mint (Ubuntu 14.04.5 LTS)

There is no Java9 for the ARM (e.g. Raspi) so it’s useless to try and update

Dmitriy · October 1, 2017, 9:14am

Ok guys. I found an easy way to make builds for Java 8 and Java 9. So we will release 2 builds every time.

For java 8

server-0.28.0-java8.jar

For java 9

server-0.28.0.jar

Lichtsignaal · October 1, 2017, 9:15am

You sir, are the best!!!

langtupt · October 1, 2017, 9:16am

Ok Bro thanks you very much

ThatGuy_ZA · October 2, 2017, 6:52am

Thanks @Dmitriy - I was wondering why I couldn’t install Java9 on my Rpi.

vshymanskyy · October 3, 2017, 8:21pm

No need to bother, just use a dedicated java8 version.

Lichtsignaal · October 5, 2017, 8:48am

Because there is no ARM version yet released. Keep an eye out on the Oracle website for updates

s.d.engineering · October 5, 2017, 10:05am

@Dmitriy
The Source Files is for which one(Java8 or 9)?

Dmitriy · October 5, 2017, 10:16am

@s.d.engineering Both should work. You may specify java8 profile as default in main pom.xml. (Right now default env is Java 9) - https://github.com/blynkkk/blynk-server/blob/master/pom.xml#L68

Gunner · October 6, 2017, 5:07am

I recently updated to the latest Java 8 version, but it seems to crash after a few (aprox 6-8) hours…

I just have default logging and this is all that shows… any ideas? or do I need to change logging options?

21:20:04.340 ERROR- Unexpected error!!!
21:20:54.801 ERROR- Unexpected error!!!

psoro · October 6, 2017, 6:29am

Same issue here but only once and without the “ALogin” line

Dmitriy · October 6, 2017, 10:54am

@Gunner please take latest server version 0.28.1. Do you see the same? Also, yes DEBUG level may help find a reason.

Gunner · October 6, 2017, 7:28pm

OK, system had crashed again last night… so I just updated to 0.28.1 and DEBUG level… will see how it goes.

Gunner · October 7, 2017, 6:57am

Well, it seemed to last about 11 hours this time… however I have no idea what the debug logging says about the issue.

It is apparently too long to post here in its entirety so this was the only clear error message I could see:

12:39:12.751 ERROR- Error reading reporting data. For user XXXXXXXX@gmail.com. Error: null

And this was from the last few hours of the Blynk log:

@Gunner could you please check with this build - https://github.com/blynkkk/blynk-server/releases/download/v0.28.1/server-0.28.2-SNAPSHOT-java8.jar and send me full log to my email?

Franchelli · October 10, 2017, 8:39am

I am a beginner and I ask for help:
I installed the latest version of the server on a Raspberry following the instructions. From the terminal I get this error:

pi@raspberrypi:~/Blynk $ java -jar server-0.28.1.jar -dataFolder /home/pi/Blynk
Java HotSpot(TM) Client VM warning: You have loaded library /tmp/libnetty_tcnative5958483406063671453.so which might have disabled stack guard. The VM will try to fix the stack guard now.
It's highly recommended that you fix the library with 'execstack -c <libfile>', or link it with '-z noexecstack'.

Despite this error, it seems to me that the server works …
