Because I was impatient, I already had my own unspent transactions working by interpreting the pages already provided by bitcoin abe.
I would get the all the adresses (/bitcoin-abe/address/). If it had any balance I would make a list of the transactions, sorting input and output transactions. I would then fetch all the input transactions to see if the transaction was already used in an output transaction and would then subtract that transaction from the output transaction list. The remaining transactions are the unspent transactions.
This way is a lot faster then your unspent api call, maybe you could one day look in to it.
(and I hope you still use your donation address, because that is where I sent the coins to)

Is there an easy way to get all unspent transactions out of a list of bitcoinaddresses?
And is there maybe a server on wich I can test stuff on?

Hi folks, hello developers (i.e. John Tobey),
Hi!
I am playing with the thought of implementing this on my server, since I am already running a full 24/7 BTC-node, LAMP and still have some HDD-space left. Also, since the main fallibility of P2P-Networks is the fact that the truth is determined in a democratic process, you can't have enough block explorers with different blockchain-sources out there.
Nevertheless, I have a problem with understanding the license this was published under: Let's say I want to change the look of the site by rewriting a bit of the CSS-sheet and adding a different logo, I basically have to publish the new sources, even for small derivations, right? But I am allowed to do so, even commercially (aka. linking the logo to my site, which is adversing and therefore commercial...)

Right. One easy way to respect the license is to get an account on GitHub (or another public Git service like Gitorious) and maintain your version there. They give you plenty of handy features. If it is just a logo and CSS changes (branding as opposed to functionality) I don't care. If this becomes a sticking point, let me know and I will try to fix it by adding exceptions to the license.
Second question: Is anyone running this on MySQL? How big is the database when finished, and is there a somewhat linear relationship to the size of the blockchain (one might assume so...)? Had it loading for a few hours now and got to block 143000, it's around 2.9 GB so far.
I think it is roughly 4-5 times the sum of the block file sizes. You can check which block file it is on and how far along it is by reading the datadir table as it loads. blkfile_number=1 means it has not finished reading blk0001.dat. blkfile_offset is how far into the current file it has processed. If blkfile_number is greater than 1, add the sizes of the lower blkNNNN.dat files on disk.
Code:
mysql> select * from datadir;
+------------+------------------------+----------------+----------------+----------+
| datadir_id | dirname | blkfile_number | blkfile_offset | chain_id |
+------------+------------------------+----------------+----------------+----------+
| 1 | /home/bitcoin/.bitcoin | 1 | 699231568 | NULL |
+------------+------------------------+----------------+----------------+----------+
Thanks for the code and all the hard work!
You're welcome and good luck!

edit:
Just some arbitrary data points regarding database size (MySQL) and block number...

Block 200000 14.9 GB
Block 216276 22.9 GB (full chain January 12th 2013)
Got bored and built LAMP on my gentoo home box. Had the database done within about 18 hours (some delay due to full hdd, note to future self: default Gentoo my.cnf has binary logging enabled) Speed benefits from giving innodb some 6GB ram. Should have done some multithreading, but most of the load still comes from read/write-operations, even with excessive buffering. So one 3.3 GHz Phenom II core might have gotten slightly warmer. Good news is: I will maybe be able to host an instance on my VPS for a few weeks before the size of the blockchain and the database eat my 40 GB HDD. Yay, I guess

This is a decidedly newbie question- but how can I safely turn off ABE? I have installed it to install Electrum, but once it's running, how do I turn it off? So as to not have any conflicts?
thanks!
Ctrl-C it from the command line or use "kill" in Linux. Don't worry about the stack trace that it prints. One of Abe's strongest (IMHO) features is its ability to recover automatically from interruption.thanks!

Thanks for the report. I've replied on GitHub. Unfortunately, I don't think it will be easy to debug, since it appears to depend on the order the blocks were loaded, and that in turn depends on network timings. I will post when I have time to address this. Meanwhile, I suggest using an older version of Abe, either v0.6 or the Sept. 15 commit (fc10484).
I think this is fixed. It turned out to depend not on block order, but on duplicate coinbase transactions. If this works out, I'll call it 0.7.2.
When designing the query I wanted to see the resulting sql string. How can I set the loglevel of store.sqllogger without modifying the python code in Datastore.py?
--log-sql shows all queries' SQL and parameters. This is currently just a boolean switch. To set the level to something other than DEBUG, you would use log-sql and a custom logging config with (for example) "loggers":{"Abe.DataStore.sql": {"level": "INFO"}}.

Thanks. I have fixed this error and many others related to out-of-sequence blockfiles.
I find it strange that the first block in your blockfile has 308 transactions. That is the meaning of the "block_tx 1 308" message. Perhaps bitcoind has become creative in the order in which it saves blocks to disk. This may slow down Abe's initial load too much. Please report the version of bitcoind that created your block file (and the currency if not BTC) so I can check.
Nice! Thanks for your work.
