Hm. By comparing this pull request
https://github.com/bitcoin/bitcoin/pull/886/files
and comparing it to the code here
https://github.com/bitcoin/bitcoin/blob/master/src/bitcoinrps.cpp
https://github.com/bitcoin/bitcoin/blob/master/src/rpcblockchain.cpp
it seems like it is NOT possible today. Oh well. I will do it on transaction-by-transaction basis. (I wanted to use Blockchain.info API but they are mysteriously missing some blocks from their API results. Oh well.)
Topic: 0.7 gettransaction/getblock RPC calls (Read 7286 times)
Hello.
I stumbled on this old thread while researching about bitcoind.
Is the decomposition with getblock possible in the newest (0.8.1) bitcoind? And if it is, how? (Your options return just errors.)

Finally! I can write my own Bitcoind to Mysql db systems with little effort 
Thank you Devs, this is great!
Is there some more information on this batch mode available? Would it also be possible to request in one call information about many unrelated TXs (because you mention "all transactions in a block"...)?

See "Batch Mode" in the JSON 2.0 spec: http://www.jsonrpc.org/specification
Yes, you can request information about many unrelated transactions in one call.
More discussions in IRC today prompted further tweaks to this API:
"get any transaction, even transactions that aren't in your wallet" functionality will be moved from gettransaction to a new 'getrawtransaction' API call, for two reasons:
1. It doesn't 'feel' right to mix the high-level info with the nitty-gritty low-level detail.
2. We think there's a potential for security vulnerabilities if there are existing services that assume that 'gettransaction txid' returns an error for any transaction not in the wallet (as it does in all previous releases).
So the new plan is to put the new functionality in a new RPC call:
getrawtransaction [verbose=0] : If verbose=0, returns a JSON string that is the hex-encoded, serialized transaction. That is the "machine readable, as concise as possible" use case. If verbose=1, returns a JSON object with all the nitty-gritty details, to cover all the other use cases.
Also, Jeff already has a pull request for JSON-2.0 "batch" functionality, so if you need information about all transactions in a block or all of a transaction's parent transactions you can get it with one RPC round-trip.

I mostly work in C#, but I'm sure its true for other languages too, creating a data structure that you can deserialize an array of different types into, and easily work with is...painful.
Excellent point. I use python, which just works with different types in arrays, and C++/json_spirit, which also just works, but I can that other languages would be painful.I'll go through the raw transactions API and will replace any "Array of different types" with "Array of Objects".
Just a personal opinion more than anything else, but I think this
should be an array of object rather than array of array so that it basically matches the output of listtransactions.

Each output is a 5-element array that is [txid, output, scriptPubKey, amount, confirmations]

An example...
getblock as it is now in pre-0.7, with decompositions: (1 command, that returns the information requested)
With this functionality removed and adjusted as Gavin is proposing, you now need 1+N calls (N = number of transactions in the block) before you have the data, and those N calls all do a lot more disk I/O since they return more information than you necessarily need:
getblock as it is now in pre-0.7, with decompositions: (1 command, that returns the information requested)

A month or two ago Pieter and Luke wrote code to modify gettransaction/getblock to return information about any transaction in the blockchain and a new 'decompositions' Object argument was added to those RPC calls that would let you specify 5 different ways to get information about transaction inputs and outputs (no/hash/hex/asm/obj). So you might do:
I think 5 different ways of getting (or not getting if you specify 'no') the information is 4 too many, so I'm modifying the code as follows:
How about not removing much-needed functionality (forcing people to go back to patching bitcoind to add it, instead of being able to simply use it vanilla/unmodified) against a general consensus (when you originally brought this up on IRC, I don't think anyone agreed with removing it)? It was added for good reason, and should remain... what good reason is there to make things slower, more difficult to use, and less flexible?Code:
gettransaction 0e3e2357e806b6cdb1f70b54c3a3a17b6714ee1f0e68bebb44a74b1efd512098 '{"script":hex}'
I think 5 different ways of getting (or not getting if you specify 'no') the information is 4 too many, so I'm modifying the code as follows:
This does mean getting full information for every transaction in a block means more than one RPC call, but Jeff has a pull request for JSON-2.0 "batch" calls, so getting full information about every transaction in a block will be just two RPC round-trips (one getblock, then one batch with a bunch of gettransaction calls in it).
This doesn't help most use cases at all.
Will it be possible to have a pruning algorithm/method that still keeps transaction hashes per block, so if I prune transaction "123abc" from my database, I still know it was in block 12345 and could request that full block from the network eventually? Or might it be the case, that the whole network pruned away that transaction and all that is left is it's hash (as far as I understood, that's how merged mining works for example).
I personally really would like to see also input addresses or at least a very easy way to get to them. What was a little confusing for me for example was the case when I have a input transaction that actually went to multiple addresses (10 BTC to 1bitcoin123 and 20 BTC to 1bitcoin234). How do I then easily determine which of these 2 outputs was used as input to my actual transaction I'm interested in?

My work on the 'raw transaction' API has me thinking hard about the gettransaction/getblock RPC calls. I want it to be easy for the information returned by those calls to be used by the new createrawtx/etc API calls.
So: in version 0.6.3 and earlier, gettransaction would only return information about transactions in your wallet, and would not return all of the information about the transaction.
A month or two ago Pieter and Luke wrote code to modify gettransaction/getblock to return information about any transaction in the blockchain and a new 'decompositions' Object argument was added to those RPC calls that would let you specify 5 different ways to get information about transaction inputs and outputs (no/hash/hex/asm/obj). So you might do:
I think 5 different ways of getting (or not getting if you specify 'no') the information is 4 too many, so I'm modifying the code as follows:
This does mean getting full information for every transaction in a block means more than one RPC call, but Jeff has a pull request for JSON-2.0 "batch" calls, so getting full information about every transaction in a block will be just two RPC round-trips (one getblock, then one batch with a bunch of gettransaction calls in it).
And to be clear: these changes are meant to be 100% backwards-compatible with getblock/gettransaction in version 0.6.3 and earlier. We're talking about extra arguments and extra information in the returned JSON objects.
Example output for a complicated multisignature testnet transaction:
Short, in-wallet transaction:
The only feature that bothers me is reporting 'addresses/type' for transaction inputs. It bothers me for two reasons:
1) It is expensive to fetch that data, because it means finding the previous transaction in the blockchain and fetching it from disk. It violates the principle that "a feature shouldn't cost you anything if you're not using it."
2) If "we" implement spent-input pruning (Pieter has some fantastic early results) that data might not exist.
I think it would be better to remove the 'addresses/type' information from gettransaction output, so gettransaction never has to lookup previous transactions.
If you care about the previous transaction, then you would have to call gettransaction again, using vin.prevout.hash to look them up (and, again, using the JSON-2.0 'batch' feature to lookup all the prior transactions in one RPC roundtrip).
If/when transaction pruning happens then the semantics are clear: that gettransaction would return an error if the prior transaction was pruned.
So: in version 0.6.3 and earlier, gettransaction would only return information about transactions in your wallet, and would not return all of the information about the transaction.
A month or two ago Pieter and Luke wrote code to modify gettransaction/getblock to return information about any transaction in the blockchain and a new 'decompositions' Object argument was added to those RPC calls that would let you specify 5 different ways to get information about transaction inputs and outputs (no/hash/hex/asm/obj). So you might do:
Code:
gettransaction 0e3e2357e806b6cdb1f70b54c3a3a17b6714ee1f0e68bebb44a74b1efd512098 '{"script":hex}'
I think 5 different ways of getting (or not getting if you specify 'no') the information is 4 too many, so I'm modifying the code as follows:
- getblock doesn't change from version 0.6; it returns a list of transaction id's in a "tx" Array.
- gettransaction gets an extra boolean argument that defaults to 0 (false). If non-zero is passed, then it is verbose and outputs information about the transaction inputs and outputs in all the different formats (same as what decomposition "obj" does).
- for compatibility with the 'raw transaction' API calls, gettransaction always return the full serialized-hex-encoded transaction data as a new "rawtx" field.
This does mean getting full information for every transaction in a block means more than one RPC call, but Jeff has a pull request for JSON-2.0 "batch" calls, so getting full information about every transaction in a block will be just two RPC round-trips (one getblock, then one batch with a bunch of gettransaction calls in it).
