NRS v1.4.12
« on: February 04, 2015, 07:20:57 pm »

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Release 1.4.12

https://bitbucket.org/JeanLucPicard/nxt/downloads/nxt-client-1.4.12.zip

sha256:

cbfe586bc4459efda5f973f32e0c9d8dcef222d9695092aa5b0dcab3c518ec9e  nxt-client-1.4.12.zip


Change log:

Improved fork resolution by allowing a better difficulty block pushed from a
peer to replace the current last block.

When forging, do not accept a peer block with hit time after the next hit time
of a currently forging account (i.e. prevent front-running in forging).

Removed the possibility of a forger to miss his turn. Even if late, the block
will still be generated and submitted.

Delay forging and submission of blocks by 20 s, configurable via the
nxt.forgingDelay property, in order to be able to accumulate more transactions
in the forged block. The arrival of a front-running block from a peer however
cancels that delay and the next block is generated up to 3 s earlier instead,
which can be controlled via the nxt.forgingSpeedup property.

The above time shifts apply to the physical time of block generation and
submission only. Block timestamps are always fixed by the forging algorithm
within 1 s accuracy, and are not possible to modify.

Better logging of peer networking errors. Log, but do not blacklist missing or
malformed JSON responses.

UI for adding and blacklisting peers. Blacklisting from the UI is possible
only when admin password is not needed (disabled or running on localhost).

Database optimization. Moved the public key of accounts, transaction senders,
and block forgers to a separate table, resulting in 15% reduction of total
database size. This change will be performed at first start and will take some
time. A shutdown after the first start is recommended to compact the database.

Forging API improvements: getForging and stopForging now allow access using
admin password instead of account secret phrase. This respectively retrieves
the status of, or stops the forging of, all currently forging accounts. As
with other admin password protected APIs, password is not required when the
API server is listening on the localhost interface only. The getState API now
also returns a needsAdminPassword boolean, to indicate this.

Enforce that the nxt-default.properties file used matches the version of the
current release.

Added currency distribution dialog invoked using a link from the currency
transaction info dialog.

Some interesting changes to forging conditions, it will be interesting to see their outcomes.

Great! Thanks for your work!

Removed the possibility of a forger to miss his turn. Even if late, the block
will still be generated and submitted.

How is this achieved?

Just using the calculated hit time as a block timestamp instead of the current physical time, even if it is in the past (unless it is more than 1 h in the past).

On my 1GB Ram VPS database conversion took around 10 minutes.

Database size after conversion is 2.5 GB:
-rw-r--r-- 1 root root 2529517568 Feb  4 20:01 nxt.h2.db

Database size after orderly shutdown of the node to allow it to compact the database reduced size to 945 MB:
-rw-r--r-- 1 root root 949544960 Feb  4 20:06 nxt.h2.db

Upgraded without any problems.
DB size went from 1,094MB to 926MB on a windows machine, so your 15% seem to be accurate.

My json api check also found a minor change in the getForging reply, it now also returns account & accountRS.
Other than that, no changes detected.

Keep up the good work!

Could you please add also NRS version in zip filename or some note in download dialog in order to know, that it is database of the latest version. It will be good to know, because some versions need to rescan/rebuild database and it takes long time on older PC. My PC is Intel i5, 8 MB RAM, windows 7, 64 bit, but upgrade to 1.4.12 is taking approx. 1 hour and it is not finished.

Makes sense will do that. 8 MB RAM?  :D

Ups, 8 GB  ;D
Anyway, it take ages for me to update database on my PC. Maybe because I'm running also NODE, NEM, NHZ on the same PC?  ;D
1 hour and 10 min, still updating database.

Hey guys, I downloaded the new version and ran it, but it still shows up as 1.4.11 and says I need to update. The zip file says x.12 though. Is there any chance that the zip file is the wrong version?

Most likely you're seeing the previous version stored in the browser cache. In the login screen, press Ctrl + F5 to force a refresh of the page, then log in.

I'm having an issue with searchAssets/searchCurrencies/searchDGSGoods.  On multiple nodes they aren't returning any results.  1.4.11 seems to be ok.  I didn't see anything in the properties file relevant to search, is anyone else having this issue or am I missing a configuration option?

Sometimes the lucene search index gets corrupted, although I haven't seen that happen on upgrade from 1.4.11 to 1.4.12. Try doing a luceneReindex from the debug APIs.
