May Bitcoin be touched by his Noodly Appendage

Is it possible to convert tx_k tx_v to a raw transaction that can be sent by sendrawtransaction from within the newer clients?

tx_k is useless because it is '027478' (well I think so) + little endian tx id
As far as I can remember, tx_v is not only the transaction: the bitcoin client adds some data (the transaction of its inputs if the client has them in its blockchain)
So depending on what you're trying to do you can use it directly or parse it to put it in the newer client

Don't worry, it's your project after all.

I would vote for a CLI. A seperate GUI is fine as well. A single pywallet with additional dependencies makes this great tool harder to use. But it's your tool - you decide.

It's my project but I'd prefer if people like using it and find it practical
Also, I make all dependencies optional: currently you can use pywallet even if you don't have twisted+zope, you just won't be able to use the WUI. Same for ecdsa package and signature/verifications
The new pywallet would follow this rule as well

Do you think pywallet would be more practical as a Qt app?
As I said earlier I'm wondering about recoding everything. It's far from sure but if I decide to I'd like to know how to make it more user-friendly.

I like putting everything into a single file because I find it easier to track and easier for newbies
I can split it in three though and then push the four files to github

Yeah, the CLI is the priority anyway

+1 to command line

It would be nice if the project was separated in three files to be able to look over it more easily:
- core functions
- command line interface
- gui/web interface

To everybody
Do you think pywallet would be more practical as a Qt app?

Just as K1773R, I'd like to have a full working command-line interface, and am comfortable enough with a web browser for point n click usage.

I'm glad that worked and that is quick
I didn't even think that exit would raise an exception, it's ok now

You both confirm what I was afraid of, that that'd nice to have CLI+GUI+WUI
I think I won't use the twisted package anymore to deal with the WUI though, I'll manage sockets myself
I'm fed up with dependencies

just tried and it tooked 5.5 minutes to delete all the 232386 transactions that was in my text file.

Great job, and thank you.

but after deleting it's showing the following:

"232386 elements deleted
Error: do not try to delete a non-existing transaction."

looks like it's raising an error on the command "exit(0)"

a GUI interface will be cool, as far I start earning some money with my project I will support this development.

It's done, please try

To make it faster I don't catch exceptions so if you provide at least one transaction that isn't in your wallet it will crash without telling you which one
Maybe you prefer catching exceptions and avoiding all the deletions to be canceled just because one failed, just tell me what is better

I added the exit code 1 in case of failure

full CLI (ie the same capabilites like the WUI) and a WUI should be doing fine.

That's not possible, and that's what I meant by "the way Bitcoin stores txs": the key is "tx"+hash(tax). So you can apply what you proposed only if you know the hash.

Hmm, wait, I just get it, yes we have the hashes because you use the file to store them... I don't know why I thought you were using 'all'
There's some hope for speed improvement then!

Can this work on jailbroken iOS?

Yes absolutely. I made it work on iOS 5.
Look if there's a Python port for your iOS. If so that should work.

hi, I looked your new code and, as you said, maybe it won't change the performance to much.

I was thinking in something like this:

at line 1779

Quote

   for i in range(len(kd)):
      keydel=kd[ i ]
      if typedel == "tx" and keydel "all":

         db.delete(key)
         deleted_items+=1
      else:
         for (key, value) in db.items():
            .
            .
            .

Do you think it is possible?

Regards

I made a small improvement
I'm not really sure it would change a lot though. I don't think it might make it faster than now, because of the way Bitcoin stores the txs

Question: in the line of code "db.delete(key)", if the "key" don't exist, will it raise an error or it will pass without problem?

It looks like that it passes without problem. Actually the delete function searches in all the DB to find all the keys to delete, so my method is pretty dumb...
I made it at the beginning of my fork, which corresponds to the beginning of my learning of Python/serious programming. The more I look at the code I made, the more I find it ugly

Quote from: BRules on May 22, 2013, 11:07:11 PM

My suggestion: when deleting transactions, instead of applying the modifications on the "key" to compare to the "keydel", why not just transforming the "keydel" to the "key" format and deleting it without iterating through all the wallet keys?

Yeah that's better that what's done currently, but as I wrote the delete function will take care of that even better

Hi,

I downloaded your new pywallet, modified my program to generate a file with all my transactions ids and started pywallet with the multidelete option.

After 15 minutes running I decided to interrupt the execution of the pywallet and start investigating your python code to try to determine where the problem is (I never worked with python, but as a programmer I haven't problem undertanding it.) and I think I found it.

The problem is that my file has about 200k transactions and my wallet has at least 200k+70k(addresses) keys. Well, if for each transaction in the file, it will interact trough all the keys of the wallet (I didnt' see anywhere in the code where you break the iteratioon of the second "for" when finding the key), so the pywallet will need to do a total of 54 billions of iterations.

So I was thinking a bit and I have a question and a suggestion.

Question: in the line of code "db.delete(key)", if the "key" don't exist, will it raise an error or it will pass without problem?

My suggestion: when deleting transactions, instead of applying the modifications on the "key" to compare to the "keydel", why not just transforming the "keydel" to the "key" format and deleting it without iterating through all the wallet keys?

Regards.

I just pushed the new version: no more '#' bugs in passphrases and you can use file for deletions

Format: 1st line=type ('tx' or 'key'), then 1line=1data to delete
Code: pywallet.py --multidelete file.txt [--wallet wallet.dat] [--datadir /bitcoin/directory]

Code: (file.txt)

tx

etc...

by the way, I received the following error when making the dump (but it completed successfully):

2013-05-22 18:36:52-0300 [HTTPChannel,2,127.0.0.1] Wallet data not recognized: {'__type__': 'orderposnext', '__value__': '\xc1\x8b\x03\x00\x00\x00\x00\x00', '__key__': '\x0corderposnext'}

That just means that the 'orderposnext' entry in your wallet isn't recognized. That is because I personally don't know what it is and I doubt it's useful.
Pywallet will keep it inside your wallet when you import/delete/dump/whatever though, it just doesn't understand it
