Congratulations on the new release!

Minor bug report:

When syncing from scratch the "days behind" is off by a factor of two.  I did not look at the relevant code yet but assume that the proper equation going forward (for 2 minute blocks) was improperly applied to the "days behind" notifications for historical (1 minute) blocks.

Noted here: https://github.com/monero-project/bitmonero/issues/591

Congratulations and thanks to all who made v0.9 possible!

I downloaded the linux64 binaries today as well as blockchain.raw. I used this to create the blockchain (used my actual path to download.raw):
sudo blockchain_import --input-file /path/to/your/download.raw --verify 0

After that process completed, I ran this command:
sudo ./bitmonerod

...and got this error message:

The blockchain is stored on disk first and foremost.

Your OS might or might not also keep some portion of it in memory as a form of caching, depending on the amount of other memory usage on your computer.

Looks like maybe a problem with the import tool. While it is being investigated I suggest you just sync from the network instead. Most people have found that to be fast and efficient.

Also, you shouldn't really need to sudo for the daemon, it should work fine without privileges, though now that you have done it once the permissions on your .bitmonero folder might be messed up. Try renaming it to something else.

Is the daemon supposed to pass blocks synced during a session out of memory?

The blockchain is stored on disk first and foremost.

Your OS might or might not also keep some portion of it in memory as a form of caching, depending on the amount of other memory usage on your computer.

The synced blocks during my sessions have been appearing in memory and grow until my memory is maxed out. These are cleared only when I exit the daemon.

The blockchain itself is being saved to disk, but my ram usage grows with each reported synced block. I am syncing from nothing. My programs hang as the memory becomes maxed out.

Is this a bug?

XMR is doing great today and seems to have found a bottom around .001

I wonder where it's going to go from here.

That does not sound like you are using the current version. The usage, as I said, may increase if your OS decides to keep some of the blockchain in RAM as a cache. But that should not cause anything to hang. The memory usage should be freed up if needed.

But perhaps there is some other problem. It is hard to say on a forum. Maybe go freenode IRC, channel #monero, and see if someone can help you figure out what is going wrong.  https://webchat.freenode.net

I'll try resyncing from scratch again, as I'm almost caught up.

The version I am using is the HH release from github yesterday, windows.

It put 1.59 GB from my most recent session into memory over one hour. Note this is not what It starts up with, which is around 200 Mb. Just figured I'd ask, because I remembered you posting that it only took up a few hundred mb as well. In total it took 1.79 Gb before I restarted it.

TY smooth.

As I said it will use what you have. If no other programs are using the memory, then your OS will give it more (especially during sync). If other programs need RAM, the memory usage for the node will shrink down to almost nothing (especially once synced).

However, you shouldn't see anything hang. That was what I thought pointed to a problem.

I can't rule out that there is something else wrong with the OS currently.

Give me a few hours, I'll have a duplicate fresh OS installation on this HW and get back to you.

Hydrogen Helix runs fantastic on OSX. 
Any plans for implementing the terminal buttons? (Tab for filling in, and up arrow for last command)?

Thanks!

rlwrap works on Linux (mentioned at the end of the README file). I don't know if there is an equivalent utility on OSX.

Cant wait to try the new version!

So the new default directory to store block chain data in  is C:\ProgramData in Windows?

Crosspost:

Interesting comment from Shen about multisig

yep - very likely will be implemented in conjunction with the ring ct stuff

Following the "written up" link in the Ring CT post, section 4.4 of the paper describes how to implement "Ring multisignature". Some of the other CryptoNote coins have multisig, but only with 0 mixin.

Very nice work being done on the crypto front.

I have replaced Monero 0.9 beta files with the ones in the final release. Started bitmonerd.exe to sync block chain. After fully sync-ed for a while, Monero still occupied 1,300,000 - 1,600,000 K (1.2GB - 1.5GB RAM) for Working Set (shareable memory) and 56,000K (55 MB Privating Working Set)

Yes the so-called shareable memory is caching of the database file, and will be freed up as needed by the OS. It is called shareable because theoretically there could be multiple applications accessing the database sharing that memory, although that isn't the case in this particular usage.

PS: It seems I can now add some quote below my name in the "Hall of Fame". This is this quote I'll choose:

Crypto may offer a way to do "key blinding".  I did some research and it was obscure, but there may be something there.  "group signatures" may be related.
