After installation z-nomp the section Network Stats does not work. Everywhere shows 0
Any help please

WaveringAna · 2017-05-04T19:50:29Z

Did you upgrade z-nomp or is this happening with a fresh install?

Is this hash a block hash?
It may be trying to find a blockhash in an array and its missing causing the null exception...
I assume it is when you try to view stats.html in your browser?

WaveringAna · 2017-05-04T22:51:07Z

yup http://aayanl.tech:3001/insight/block/00000001967d4765f0579b46feab6adf2ca59911e647d6a0d33937dd2d1c8efc, @GRinvest what version did you update from?

GRinvest · 2017-05-04T23:12:31Z

This is a new installation. First I did it from here https://github.com/z-classic/z-nomp.git After I found the block This error was received. After that I installed from here https://github.com/hellcatz/z-nomp Get the same error. Pool not work After do redis-cli FLUSHALL and restart And work again. Also does not show section Network Stats Everywhere shows 0 http://zcl.minecrypto.pro/stats

WaveringAna · 2017-05-04T23:13:24Z

well, FLUSHALL clears the redis DB completely hence the 0

GRinvest · 2017-05-04T23:14:47Z

not show section Network Stats

hellcatz · 2017-05-04T23:45:53Z

As a test, if you clear the contents of website/pages/stats.html does this fix the problem?
(This will make the stats page blank on the pool of course, just trying to locate the exception...)

GRinvest · 2017-05-04T23:56:29Z

I cleaned up the page. I'll look at the result and write

WaveringAna · 2017-05-05T00:30:19Z

I'm getting the same error as well

This is with the pplnt pr

WaveringAna · 2017-05-05T00:38:03Z

Restarted z-nomp and founder another block and didnt crash

WaveringAna · 2017-05-05T00:38:14Z

I'm guessing it only does this with the first block

hellcatz · 2017-05-05T01:05:45Z

I believe it is something in stats.html probably do to with the confirmation lookup and the fact it's missing from the array or the array itself doesn't exist yet...

hellcatz · 2017-05-05T01:11:11Z

Possibly this line https://github.com/z-classic/z-nomp/blob/master/website/pages/stats.html#L156

hellcatz · 2017-05-05T01:42:55Z

Issue resolved with latest commit to patch-6. https://github.com/hellcatz/z-nomp/commit/8d5a13697f21e26163aa55567a00f9d54f9275b8

The problem is when the very first block is found :blocksPendingConfirms doesn't exist in redis; thus,
it.stats.pools[pool].pending.confirms doesn't exist when stats.html is generated.
This causes a null exception when if (it.stats.pools[pool].pending.confirms[block[0]]) is called.
The added if statement prevents the failure mode.

From the log below, I reproduced the crash. Reloaded the patched stats.html and no crash.
