Topic: [ANNOUNCE] Abe 0.7: Open Source Block Explorer Knockoff - page 30. (Read 221044 times)
John can you help me out with the explorers i'm trying to get going i'vew sent you a couple msgs but not sure what to do to fix this
this one for Noirbits fails.
It appears to trap the error at line 511 in abe.py
I really appreciate your help trying to figure it out.

This does not look like the latest version. Please update and try again. The current version has this at that part of the code:
Code:
510 if total_ss <= 0:
511 percent_destroyed = ' '
512 else:
513 percent_destroyed = '%5g' % (
514 100.0 - (100.0 * ss / total_ss)) + '%'
If I click the >> link to browse to the beginning of the block chain, python barfs a big purple "division by zero" screen. Happened on a few of the abe installs I looked at. I'm testing mine for Doubloons at http://explorer.doubloons.net/chain/Doubloons.
Any help to identify the problem would be appreciated.
Interesting. Please update and see if this fixes it. The genesis block has zero output value, first time I've seen that. No premining there!Any help to identify the problem would be appreciated.
I updated, but it still occurs. I've been setting up block explorers for a few alt coins. Some work fine, like this one for Xencoin (also, holy shit look at that pre-mine!) but this one for Noirbits fails.

Hello John again i'm getting errors i've tried what you told me it just skips the blocks not sure why than this
block_tx 8470 8734
Skipped 72 bytes at block end
block_tx 8471 8735
Skipped 72 bytes at block end
block_tx 8470 8734
Skipped 72 bytes at block end
block_tx 8471 8735
Skipped 72 bytes at block end
This is not an error, just a warning. This coin puts some extra data at the end of each block beyond what Bitcoin puts. Abe does not know what it is for, so it skips it. Can you browse the site?
i deleted the chain and let it run with --rescan, it imported more blocks but it fails once again! same error, look at the crazby block file count
The block file number 100001 is okay, it just means blocks/blk00001.dat as opposed to the pre-0.8 ./blk0001.dat.
As for the Merkle Root Mismatch, I would guess that Testnet3 is trying some new block format. I would be curious to see the raw data between offset 622216 and 622305 in your blk00001.dat file.

right, i got a problem with the testnet chain:
what should i do to fix it? redownload chain and running with --rescan?

Mega uses scrypt as well. The main difference between mega and the other ltc clones that have come out is Mega uses the new 0.8.2 bitcoin code while litecoin and others use an older code base.
Scrypt is just the proof of work algorithm. Bitcoin uses sha-256 while bitgem, litecoin and most other new coins use scrypt. the main differance from ppc and novacoin are that nvc uses scrypt. Novacoin also has a pos roi which is calculated by the pos difficutly but yes basically ppc

If the coin is derived from PPCoin/Peercoin, try the "ppcoin" branch (git checkout ppcoin).
is it possible to have a 4 char code3, for example TBTC for Testnet Bitcoin? (according to README not, is this just a "you shouldnt do this" or a "this wont work and fucksup everything")
dislike to try it out on my finally synced Abe and screw it up
if i change it to 4 chars in MySQL, will it work or does Abe bail out on it?
Well, I don't think it will cause any big problem within Abe. Currencies traditionally have 3-character codes, so I named it char3 and made the column 3 wide. If you widen the column and put in 4 chars, it will not break the database.dislike to try it out on my finally synced Abe and screw it up

Please try with "default-loader=blkfile" in your abe.conf, or try the workaround I just pushed to GitHub. To make RPC work, we will have to find out how this coin hashes its blocks.

Most of the people need something really simple and intuitive for browsing the block chain
Any thoughts of a really light minimalistic interface?
Well, it would be nice to separate Abe more into model/view/controller. Maybe JSON versions of the UI pages, and implement the UI in JavaScript?Most of the people need something really simple and intuitive for browsing the block chain

Thanks for the Testnet3 explorer! I don't know who uses Testnet3 or how to tell them, but I'm glad to know about it.
I don't know were is the correct place to announce this

can i have a Abe with sha256d chains and scrypt chains? also where is the docu for scrypt based chains?
Did you try it? http://explorer.litecoin.net/ appears Abe based, and doesn't LTC use scrypt? I'd suggest asking them if they had to change anything. They should give you the explorer source. (If not, I'd like to know...)Abe does not (yet) contain any special code for scrypt. That would be nice to add.
