New version available at
http://www.gridcoin.us/download/gridcoin.msiRelease notes (1.1.4.9/6.4/49):
1. This version will need to be installed from the MSI; you will need to delete your program files (x86)\gridcoin directory before installing
otherwise the installation will succeed and fail later.
2. We will be expanding the installer; however this release includes cgminer3.4 in cgminer.zip,
a new query analyzer, and a new SQL server database.
3. An optional feature has been added for users who do not want any command line interfaces closed by gridcoin:
Add the following key to your gridcoin.conf file: closeconhost=false
3b. More optional features: Set key closeguiminer=false to prevent guiminer from being closed (or closecgminer=false or closreaper=false).
Note: Only add keys in step 3 or step 3b if your system requires it.
4. We have removed the cgminer files since they show as a virus, now we zip up cgminer 3.4 - the master version is installed in the AppDir.
4b. OPTIONAL: If you would like to replace Gridcoin's cgminer version with your own version
(Please see Con Colivas's downloads at :
http://ck.kolivas.org/apps/cgminer/ )
download the appropriate version and test it thoroughly (verify it supports scrypt also),
then zip your version of cgminer
as "cgminer.zip" and place it in your DataDir, and gridcoin will prefer that version when creating new instances in Mining | Configuration | GPU Miner Settings.
Note: You should only include the EXE, kernel files (.cl files) and DLLs as we do in example file "cgminer.zip" (located in your gridcoin appdir).
5. We Added scantime=7 to the cgminer create instance function,
for quicker detection of new blocks when using cgminer.
6. When adding a cgminer instance, gridcoin will unzip the cgminer.zip into the "cgminerX"
instance directory and create the cgmX file.
7. For our upcoming features related to 3rd party API checks, transaction confirms, CPU-only mining for boinc users,
and scrypt_sleep, We decided to use SqlLite instead of MySql,
due to packaging size considerations (MySQL is a 300 meg download
and it requires the MySQL connector for each OS; we didnt want to add 306megs to the
core program, and replicate that size to our future userbase of 25,000 machines
.
So far, SQL Lite has been solid; we tested the standard insert update delete and order by;
devs- please test an inner join.
8. Added the Gridcoin sql query analyzer (it's still in its infancy).
You may access it by clicking "SQL Query Analyzer" from the main page.
8a. So far, we have only added a few test tables: System, Blocks, and Peers. To keep from using system resources
we insert one gridcoin block into the database every 10 seconds. The peers are loaded once every half an hour.
To do a sample query from query analyzer:
Select * from Blocks
Etc. Or other ansi-92 standard queries.
Inserts/updates do work, but will not be stored in the database after you click close.
Note: Gridcoin has a master lock on the database, so you only receive a snapshot of the
database when inside query analyzer, (this is to protect from errors during inserts by gridcoin),
you will have to close the query analyzer window and re-open it to see new blocks.
8b. The Results pane contains a data grid of the data; eventually we will make it copy and paste into excel, etc.
8c. Note: For speed, you can type a query and press F5 instead of execute
9. TribalBob: Please let us know if 4.3 fixes the cgminer version problem that you experienced;
and also let us know if this fixes the virus scanner test.
Good luck!
