Just a cosmetic based on mobile view

This happens on the above and coin supply on mobile/laptop easy fix?

Also If you can point me in the right direction, how do I make the menu bigger in mobile view assuming it’s all css

I have tried with everything, and it gives the same respons every time i tried to start the update. All RPC connections etc are working fine with original iquodus.

This is not an issue but more of a question, i am using your explorer as you know, before all the cluster work. My question is i know you are looking at multicoin support but i am trying to run 2 explorers on one semi decent server and i am using ssl on both however

One explorer is using port 443 for the ssl, i am trying to launch a second explorer but cannot because 443 is being used even though i have use --port 445 when sending npm start, gives me the in use error.

Just wondering if you knew of a way to launch two on the same server two different url folders with all packages in each including force ssl and forever.

Any help you can provide will be much appreciated, i have also changed the default port for both 8082 and 8083 but still try's to access 443.

I think the problem i have could be force ssl trying to open the default port even though it's used. I could be totally wrong and i can't run two with ssl.

Update:

Got it working on two different ports, but i have to use the port number at the end url:441 as the other explorer has port 80 redirected to 443 and i can't redirect the same port to two different ports as far as i am aware.

Do you know of a better way to get them to work without appending the port to the url

Hi me again

lib\explorer.js:384
    module.exports.syncLoop(tx.vin.length, function (loop) {
                                   ^

TypeError: Cannot read property 'length' of undefined

Error occurs when I do a sync.js index reindex, let that run for a few moments, and then Ctrl+C and run sync.js index update.

Issue appears to be that stats.last is set to -1. So since the index failed out/crashed/ended prematurely, it didn't update db.stats. We need to update stats atleast partially during an update to make sure everything is on the up and up. Atleast it should gracefully crash/restart its operation.

So in investigating, I've setup logging with 57290e0 and because of that I am able to start focusing on where things are going wrong.

So our console is showing that we're actively getting results from worker PID:19280

But in our process tree, while we see 19280 is actively running and using memory above 64mb, (just to choose 1 worker) looking at 3588 shows no movement.

The log file for 3588 shows about the same thing too, it hasn't updated since 3:23PM, let's look at the file itself.

End of log file shows us the same thing, last thing has been 3588, and there's no update_tx_db finished. Updating stats.Last to set #####, so we're still in database.js stuck somewhere

Looking at the syncLog we see the same thing, 3588 started but there's no indication that it finished.

One thing I did run into though:

C:\Users\tim\Documents\git\official-explorer\lib\explorer.js:368
      iteration:function(){
                        ^

RangeError: Maximum call stack size exceeded

There were also Timeouts when communicating with the coin daemon. Unfortunately log4js doesn't capture those traces (and I'm not redirecting console to file). My guess is there's a try/catch that's doing throws with no returns. So we're crashing.

So, to test this out, I simply just deleted all the collections, ran "npm start" to recreate the collections for a new install, and then ran the node scripts/sync.js index reindex, or update. Either one should work fine, but it appears that because of the way we get the "end" we break.

db.update_db is suppose to set the stats.count to what the current blockcount is. Then right after all that is done, it's db.get_stats which pulls that information (a redundant call), but for whatever reason we still get left with a 0.

https://explorer.cpuchain.org/address/coinbase

When searching for a TX you get a page isn't working error instead of a explorer can't find error.
The block i tried to search was a payment to self, it does require 20 confirmations so may not be in the explorer yet.

search url goes to example.com/block/dcb75512cd2b4bb24b0f4c5d5eaa0a27cdb8ae422de8ad67f8cee1270efe576b
which is a web error rather than a explorer error.

Seems to be if the transaction isn't in the DB yet, but i think it should go to an internal error rather than browser error, not sure if that is how it should work.

We already have access to a daemon so we can use it for the purpose of "Label"ing in terms of addresses on the Richlist. We could add buttons saying to "claim" an address, then generate a message that would need to be signed. While i haven't yet gone through and figured out the inner workings, it's a popular feature on some block explorers.

We should be able to change GMT timezone to local!

Just wondered if anyone could help with this error, Clean install and running with npm start and i get the below error, i also know this is WIP but i cannot solve this issue.

I have not changed any dependencies just edited settings and run, as per a previous install without i18next.

any help on narrowing down the issue is appreciated - I also seen the error mentioned on another issue but i have the language change already as it was a recent download.

I know you can't reproduce it looking at your comments on the other issue, did you replicate the error, as i can't find any information on this.

Explorer Base: WIP PR
Commit: f9120b3
Issue reported in: iquidus#257

Merratzz is reporting that on a fresh install, running the initial sync index is resulting in an error with block.tx.length. This error is typical when there's no "tx" found inside the block. Better error checking needs to be put in place.

Other possible issue:
[ ] Settings.json.template is not up to date with the new additions. Possible user doesn't have correct settings.json format.
[ ] User casted doubt on genesis and genesis tx, not quite sure if they ran a vanilla IE install to ensure correct setup.

Currently running a test with a fresh install locally. Will check if a new commit is needed.

Entries list does not match how many blocks there are on the index page see screenshot (limit screen view due to unreleased coin)

As you can see from the image it shows 218 more entries than actual blocks in the DB and i also have "last_txs": 1000 so that doesn't make sense either.

Really like this explorer and want to keep using it, so just trying to point out some bugs/issues
Also i don't suppose you know how to show more than 10 entries on the index page or a setting or maybe make a setting in the json for show no entries 25 or something
Also i have a few more do you want separate issues for them all

Update - Nearly 300 entries more than blocks, the gap is getting bigger

api section works fine and is getting all the info such as get difficulty.

The coin has worked with the older explorers.

So an issue that I'm finding is that there's occasionally CONNREFUSED happening from the Daemon while the workers are doing their thing. After this error is thrown, the worker is stalled (#24). So we need a way for the workers to tell the master they're still working, and if they're not (but still alive) then the Master needs to kill them and start a new one in its place.

The problem is that cluster.workers[].process.env isn't a thing; You can't restart a worker (no cluster.workers[].restart, etc. You're basically just stuck with a dead process. This almost certainly has to do with the amount of communication we're throwing at the Daemon, but we really need a way to address this.

Just noticed on movement page, the result header is missing Tx-Id so the results are all shifted left

I removed

and added

 .col-xs-12.col-md-12(style="margin-bottom: 5%")
      .panel.panel-default
        .panel-heading
          strong= t('movement.latest')
        table#alerts-table.table.table-bordered.table-striped
          thead
            tr
              th.text-center= t('movement.timestamp')
              th.hidden-xs.text-center= t('movement.txid')
              th.text-center= t('movement.amount_coin',{coin : settings.symbol})
          tbody.text-center
  .footer-padding

Not sure if your code is intentional or not just thought i would mention it, spacing and tables match all other pages except network gonna look at that now.

When i enable lengthChange the dropdown shows but the header isn't like masternodes

First image does not have a header box like 2nd image, code could be wrong still working on it

Right now we've fallen behind on maintaining iquidus, I'm merging uaktags fork with iquidus master, make sure that holds and start accepting the PRs.

Uaktags had a few features:
-Logger for better logging
-i18n for internationalization

So one thing that I was thinking of, which has nothing to do with the code/project of the explorer, but I wonder how stability would be handled if there were multiple coin daemons that the workers could communicate with.

The thought process would be to either extend the settings.json to have multiple wallets, with an order of priority setup. Then the users can either set multiple guys and we'll just go in order as workers are being created (roundrobin) and use each daemon. Alternatively, test with having a loadbalancer in the mix to route traffic to a wallet. This would be perfect for those that are on public webhosts that offer such functionality (like ionos).

Currently Iquidus Explorer is a all-in-one package: The frontend nodeJS Web App that people can view to explore the BlockChain, and a backend Sync tool which does all the heavy lifting. With the enhancements of clustering (both via cpu and the possibility of using multiple systems) there's a need now to separate the two. The backend, with the introduction and soon deprecation of "use_rpc", we no longer need the explorer to be visible to the backends to do our syncing. So this opens up numerous possibilities like Multi-Coin functionality as well as building better, more diverse applications for the front end to function and grow.

A few benefits of removing the Sync from the Frontend:

• No longer does the frontend need to use as many workers to stay alive. The sync never hits the simple express app, so more resources are dedicated to visitors of the site than being used for the syncing operation.
• Syncing is now exponentially faster. Again, we're not adding an additional hop to the mix, we're going directly to the daemon and moving on.
• Frontend applications can be coded out of any language without needing the old express app running. Some proof of concepts will be posted soon.

I know this WIP just trying to iron out some issues before our coin launch, we really like the modifications you have done.

Also the icons are really close to the data in the blocks see above image were maternodes is null the icon is right next to null no space same as supply and diff ect in the blocks along the top.

Each coin is not created equal, some have their own accepted commands, some are masternodes, etc. This should be the coins job to figure out, not the explorer.

#57 and #58 will remove the old json approach I had tested before, in favor of a cleaner way to do this (hopefully)

Hi,

I have a question regarding api/getpeerinfo and api/gethashinfo

I am trying to block external calls to these to api elements and only allow localhost and server and i don't have Nginx installed so i have been trying to block them via apache but with no luck.

Do you have any suggestions on how to do this i have used in apache2.conf and 000.default.conf

<Location /api/getpeerinfo>
Deny from all
Allow from 127.0.0.1
Allow from server ip

does not seem to work from what i can tell, using apache2 2.4

Just wondered if it was possible, i know you can do it with Nginx but i would need to reset a lot of things to get it to install correctly, just hoping not too as i use SSL.

After starting reindex and after that update started running but probably (for the first time) from 10000 blocks synchronization stopped with announcement There are still 0 workers.

I have a few different versions of the iquidus explorer working successfully but i cannot get this version to run. I really want to use this one since @uaktags keeps updating and it looks solid. Id love to know what node, npm, linux, and mongo versions you are running just so i can rule some stuff out.

Thanks!

Very strange 🤔

So it was brought up/asked about making a market integration for these coin trackers. The hesitation I have comes from the fact that these aren't markets, so they're missing things that need to be shown in a market, and they provide an avg overview rather than the knowledge of what the price is currently.

However, I've already made the explorer allow multiple markets to show, we could in theory change the header widget to being a price ticket from the trackers, and still provide Market functionality with anywhere from 1 to multiple markets.

So the idea currently, discussion is welcomed, to have a setting just like markets, but to be for CMC/CG/CC, and a toggle of display the Enabled-Market or the Enabled-Tracker. The tracker would then provide a JS output of the price as a whole (CoinPage could also use some loving from this info too), and the markets will just keep their functionality.

Coininfo is missing from settings.json - i have added the setting true or false but i think i am missing something for it to show the page

/var/www/vhosts/explorer/views/coininfo.pug:31 29| h5.sub=t('coininfo.coin_supply') 30| .row.info-row > 31| if settings.coininfo.masternodes.enabled 32| .col-md-4 33| h4 #{totalMasternodes} 34| h5.sub=t('coininfo.total_nodes') Cannot read property 'enabled' of undefined

I don't think app.js looks for a toggle or index i will look at previous explorer i used to see if that is the case.

Sorry to keep adding issues, i am trying to fix these i was okay with jade but a lot of things changed and i haven't quite caught up.

So currently there's two main logic areas:
The Cluster or (app.js)
and
The Sync script.

The Cluster/app.js merely is just the explorer itself that controls the express webapp. However, this also is our linkage point to the backend coin which the Sync script relies on.

The Sync script, currently just a simple "start from Block 1 (or last sync'd block) and go up from there" sends all of its API calls to app.js and that communicates out to the wallet based on settings.json.

There's not much really stopping us from turning this into a multi-coin explorer if a few things are done first.

1. Remove "last txes" from the index page and instead give a menu/listing of coins we're indexing.
2. Change calls like /api/gettransaction? to something like /api/btc/gettransaction. Basically add a coin variable to calls.
3. Remove the sync tool from needing to use app.js at all. In theory we have enough traffic already hitting the webserver, we really don't need more from internal. Also, the webserver itself doesn't necessarily need bitcoin-core/bitcoin-node-api module for much that we can't offload somewhere else.

Number 3 is where things would probably get tricky, but my theory is this:

1. We're already needing a separate server for the daemon(s) unless you're letting them run on the same system which could lead to performance issues with users. Each daemon should have its own "sync.js application" that uses bitcoin-core (bitcoin-node-api is an express webapp wrapper for bitcoin-core) directly. This removes 1 additional request query from happening and would hopefully speed things up.
2. Each sync.js application therefore updates the mongodb which our frontend will read and display data from.

to be continued.

I started a new sync on the second server and here are the error logs I spoke about. After the last error, the sync stops. I waited for about 30 minutes.

http://coalmine.eu/sync-log.txt
I found a very similar error here
janoside/btc-rpc-explorer#49

While looking at the idea of #13, I started wondering, if we have a separate sync.js application, would it be faster to communicate via cli vs TCP/RPC. Keep the sync and daemon local to eachother, only have 1 connection outbound to the mongodb.

To test, I'm going to try doing a timed reindex of Vulc for 10minutes say 3x each. So 3x with RPC to localhost daemon, 3x RPC to a remote server on a LAN, and 3x with local cli. The goal is to see if we'll get any performance improvement.

Currently every exchange needs to be hardcoded even though we just pass the same information to it. This should be refactored to automatically load the exchanges based on settings and just pass the info correctly.

Any manual available?

I have a goal of removing cluster module and replace it with PM2. I've found it to be much easier to work with, plus i hate the use of .pids. Just let a Process Manager deal with everything.

I don't know if you tested the launch of a new database. When you first run npm , each worker creates records in db (created only once).

I could not always start the index update with the result

I am using master branch last commit july 2019 and latest nodjs and mongodb but for some reason when i try to sync the explorer with the wallet i get the following error.

and output from explorer is

I know in a previous issue this was mentioned but unsure if it was fixed, i don't have the time issue as it's only in the source code once.

Any help with is is appreciated, i am using master as it has masternode page, seems other branches do not.

I have noticed that decrypt=1 on the api url generates an error check console not sure if that is the issue

Much to the same extent as iquidus#287, this is a pinned announcement of a collection of Exchanges. I don't want to be doing any more pull requests for exchanges as they seem to come and go all the time over the past 2-3years. Instead, I'll do PR's for them at this external repo and people can pick and choose what they want.
