Confirmation number for sent BCH transaction does not increase

[bijakatlykkex]

Hello,

We have setup a bitcore node for Bitcoin Cash.

After successfully broadcasting a transaction using /api/tx/send, and after it gets mined and some more blocks also generated, the call to /api/tx/[txid] does return successfully but in the returned json confirmations keep to be 0.

{
  "txid": "...",
  "version": 1,
  "locktime": 0,
  "vin": [...],
  "valueIn": ... ,
  "fees": ... ,
  "vout": [ ... ],
  "confirmations": 0,
  "time": ... ,
  "valueOut": ... ,
  "size": ...
}

Confirmation for other transactions in the same block (not sent using the /api/tx/send) and also confirmations in /api/addr/[addr]/utxo is fine.

Helps appreciated,
Thank you

I managed to reproduce the issue on http://bch-insight.bitpay.com:

Confirmation=1
Confirmation=0

txids are the same, from url it could probably be found out the first url was captured before the second one, the first one has confirmation of 1, the second has the confirmation of 0 (it maybe needed to scroll to the end, for the confirmation field to be viewable).

One of our colleagues (@troshkin) found out that the problem could be overcomed by modifying a source line about cache, so we changed https://github.com/bitpay/bitcore-node/blob/master/lib/services/transaction/index.js#L29 to the following and problem does not appear anymore:

this._cacheTx = LRU({max:1000, maxAge : 1000 * 30});
