regarding file size
I see -size 1,95 GB (2 097 155 946 bytes) and size on disk 1,95 GB (2 097 156 096 bytes)

What does the first size refer to, if not size on disk? Where else does the file exist other than "on disk"? I guess the "on disk" figure could be rounded up to the next 4k boundary or something (it's a multiple of 4096).

I've no idea why the import isn't working for you. I've not heard of anyone else having that problem. I hope the bootstrap.dat file isn't corrupted. Did anyone else try using it recently? If so, how did it go?

I don't know, I just copied both number from file properties.

He means that in Windows, when you right click a file, it shows both.

Like....

Takes under an hour to download.

Client is importing blocks now.  Will be done by morning. 
On my laptop, it's at 30% after 3 hours.

Nite.

yes, exactly.

I don't think we expect the blk* files to be identical between different clients. They can contain orphaned blocks for example. But the total size of the blk files should be at least as big as the bootstrap.dat file since the bootstrap.dat file doesn't contain orphaned blocks.

This makes me think you're doing more than simply "cat blk*.dat > bootstrap.dat", so how are you generating the bootstrap?

Better start reading up on importing wallet

[Michail1]

Just to give an update.  I woke up this morning and noticed the bootstrap was renamed to bootstrap.dat.old ; however, it was no where close to being done.  I did not see the client running nor CPU usage.  I closed the client and restarted it.  It imediately started downloading.  So, I closed it again.

I renamed bootstrap.dat.old to bootstrap.dat and restarted the client.   So, it took a while before the client (internally, but visible in the debug.log) to catch up to the last block it has imported to the blk0001 file and continued on.

Now, just got back from lunch and found that it had finally moved on to blk0002.

Yours....

blk0001- 1,95 GB (2 097 155 946 bytes
blk0002- 195 MB (204 685 437 bytes)
bootstrap.dat.old - 2,38 GB (2 565 076 446 )

Mine....
blk0001.dat - 1.95 GB (2,097,155,946 bytes)
CRC32: EDF37145
MD5: D9F206FF08650A0CF5F8DC71735A388D
SHA-1: 9897F16A8E6AC09DD0AF41C66A2E2897482399A1
SHA-256: 510D0CABB4208D9A545A0E05FAB2C0C29C225D699E0601A16B2891FACBD2CE98

So, the file sizes match.


Question is why my client stopped importing blocks in the middle which appears to have happened to you.  Space and Ram is not an issue and running on SSD.
Maybe try to rename bootstrap.dat.old to bootstrap.dat again and restart the client again.  (Take note that it takes time internally (although visable in the log) for it to quickly go through all the blocks is already has imported.)

Very easy to do.  Remember, you had to have bitcoin (or a couple of alts) from a long time ago.

"Every person who had Bitcoin at block 300,377, Litecoin at block 565,693, or Dogecoin at block 218,556 was given ~4.6 CLAM."
(Should be corrected to say.... 'Every address'....)

You need to have held Bitcoin, Litecoin or Dogecoin on May 12, 2014 with a balance over dust in order to qualify for free Clamcoins.

My bootstrap matches; however, I am really having a problem syncing via the strap as well.

It keeps simply stopping from using the file and goes to live network sync.

Keeping a point of the log each point, I am quoting some from the various restarts of the bootstrap...

It did it again.
1781476

Basically, I can't get it to sync myself.  Several attempts and confirmed the sha256 of the bootstrap matches the dooglus post.

exactly what I told from beginning...number of attempts not change the outcome.

I am agreeing with you and confirming the same results.  Isn't it nice when two people come to the same conclusion?

Net results for me...
It works great until block 1781476.  It then runs into an error.
If I had to guess though, I would say this is when the client hits a kind of 2GB windows file limit, an error is flagged and the client then goes into syncing mode instead of importing blocks from the bootstrap.

Further issue is that my client must be restarted many times as it simply stops syncing. (Both when trying to rename the bootstrap back or simply to let it run through normal syncing.)

I am currently at:

It wouldn't be so bad if the client didn't need to be restarted all the time.

Sir I am already done with bootstrap and it makes my wallet sync fast by " importing files " now it's back to "synchronizing with the network and it takes a day now and it is so slow . I thought  bootstrap can go up to 2M blocks now it is just 1.8 M blocks ( approx 19 weeks behind ) is this correct or is there another patch I need to download ?

Well, it's basically the issue being reported.

The client only imports blocks to a certain point and then goes to sync with network.  It's either a 2GB file limit for the error or the public bootstrap is broken.
In any case, I've also encountered that the client keeps stopping and has to be restarted, but no indication on the UI.  Only that the bkl0002 stops changing in size.

I've been trying for 2 days now with no less than 20 restarts.
At block 1853826 now.... 18 weeks behind.

Hi,Dev,I want to know the latest road map of CLAM and hope to get your help. Thank you

[lolika]

whats the ETA of new wallet ? and what futures will contain ?

Oh not a good news but I am hoping that they do some changes or either fixed the issue . I really want to do staking with clam .

[dooglus]

I don't think we expect the blk* files to be identical between different clients. They can contain orphaned blocks for example. But the total size of the blk files should be at least as big as the bootstrap.dat file since the bootstrap.dat file doesn't contain orphaned blocks.

This makes me think you're doing more than simply "cat blk*.dat > bootstrap.dat", so how are you generating the bootstrap?

A bootstrap.dat file has to contain the blocks in the correct order, or it won't import. The blk*.dat files contain the blocks in the order they were received from peers, and so are often not in the correct order.

I create my bootstrap.dat files using the "dumpbootstrap" RPC in the client, which dumps the blocks out to a file in the correct order.

[dooglus]

Question is why my client stopped importing blocks in the middle which appears to have happened to you.  Space and Ram is not an issue and running on SSD.

I'm trying an import of the same bootstrap.dat from scratch. I'll let you know how it goes.

Here's how it started:

What version of the CLAM client are you using? You'll see it in the debug.log. Mine is "Clam version v1.4.17-139-gf0707d3 (2017-04-10 17:28:15 +0000)".

Net results for me...
It works great until block 1781476.  It then runs into an error.
If I had to guess though, I would say this is when the client hits a kind of 2GB windows file limit, an error is flagged and the client then goes into syncing mode instead of importing blocks from the bootstrap.

It could be an issue with 2GB filesize limit I guess, or a signed 32 bit variable in the code perhaps. 2^31 = 2147483648.

I would suggest putting "connect=0" in the clam.conf to stop the client ever going to "live sync".

Hello ! I also have the same issue and supposed to go 2M blocks but I am stack at 1.85 M blocks and its not importing anymore . Where can I find this ( calm.conf ) ?

[dooglus]

Where can I find this ( calm.conf ) ?

clam.conf is a file in the same folder as your wallet.dat. You make it yourself - it's a regular text file.

I see a problem when the bootstrap.dat reaches 4 GB, due to the use of an unsigned int, but don't see a 2 GB limit yet:

https://github.com/nochowderforyou/clams/blob/v1.4.17/src/main.cpp#L2870

Code:

unsigned int nPos = 0;
[...]
fseek(blkdat, nPos, SEEK_SET);

Edit: I tried making a bootstrap.dat file which started with 4000 MB of zero bytes and then had the regular block data. The client quickly skipped the first 4000 MB and started complaining:

2018-05-18 12:16:03 ERROR: ProcessBlock() : already have block 0 00000c3ce6b3d823a35224a39798eca9ad889966aeb5a9da7b960ffb9869db35

as expected. But then, after 96 MB of block data it wrapped around:

2018-05-18 12:16:10 ERROR: ProcessBlock() : already have block 8571 000006ff5c3a5829e0da80d9afb609435e887c51123f5afeb5f6afe5da819423

So that's the 4 GB bug, but we won't be seeing that yet.

I tried putting 2100 MB of zero bytes before the bootstrap data and it seemed to be able to skip the >2 GB of junk just fine. So I don't know what the problem is yet.

My import that I started earlier is still running. I'll leave it running and see whether it eventually fails or not.
