pytoniq's Issues

Liteserver crashed with -400 code

Hi all, I have a question about testnet.

When I use get_transactions on testnet, it usually returns -400 code for me. But when I remove the specific node and use different trans_lt to go on, other node also may throws -400. So how to resolve this problem?

Update:
Now im trying set only_archieve to true and it seems no error returned, so can i think that archieve_peer contains all data? or I have a wrong thinking?

pytoniq/pytoniq/liteclient/balancer.py

Line 234 in a5f1d15

only_archive = kwargs.pop('only_archive', False)

Thanks for everyone's answer.

Get method "seqno" for account returned exit code -256

Return hash in wallet.transfer and add send_message_return_hash method

I know that exists two request types for sending message (pytonlib supports both): raw.sendMessage & raw.sendMessageReturnHash.

Please, add ability to get hash after sending message !

python minimum version

It is worth adding to the description that for the library to work, the minimum version of python is 3.10
On older versions of python there is an error:

ERROR: Ignored the following versions that require a different python version: 0.0.5 Requires-Python >=3.10; 0.0.6 Requires-Python >=3.10; 0.0.7 Requires-Python >=3.10

  await client.connect()
  mnemo, wallet = await WalletV4R2.create(provider=client)

Non parseable transactions in specific blocks

We've been running block scanner for a few months now and we first time encountered issues with specific blocks. None of the blocks on mainnet from 37719962 to 37719966 are parseable and all fail with following error. Starting with block 37719967 all works again. Any ideas how to fix? Thank you.

How to retrieve transaction hash same as sender sees?

I'm using block scanner example and so far I only have found hash of transaction using transaction.cell.hash.hex(). But it is different of the hash that sender sees on his wallet under Sent transactions.

For example I have this hash (B circle) a8065b4a8d941e52367965b7bb7dc72af2bbb89d4095bdcc40cc1fa58feaddea:
https://tonviewer.com/transaction/a8065b4a8d941e52367965b7bb7dc72af2bbb89d4095bdcc40cc1fa58feaddea

But when letter A in the circle is set then URL changes to this hash, which also matches hash that sender sees in his sent transactions archive: 23eff21be48727416de6b71d00bfd50451227ec4972431eb95e4071bc9dafd46

But I couldn't find a way to get that hash. Is it possible?

When I use RPC API /getTransactions method using the hash I have, then transaction is successfully found however even then field result.transaction_id.hash hash not same hash I searched with, but the one that sender sees.

PS. Thank you for this useful library.

How can I get the transaction msg_data field from the in_msg?

When getting transactions from toncenter API I get a msg_data field inside the in_msg where I can get the comment of the transaction, how can I get that in pytoniq?

"msg_data": {
  "@type": "msg.dataText",
  "text": "Y29udGFjdC10cmFuc2Zlcg=="
},
"message": "contact-transfer"

No module named 'Cryptodome'

Hello, I'm trying to use the library, and I get an error:

>>> from pytoniq import LiteClient, MessageAny
Traceback (most recent call last):
  File "C:\Users\user\AppData\Local\Programs\Python\Python311\Lib\site-packages\pytoniq\crypto\ciphers.py", line 9, in <module>

ModuleNotFoundError: No module named 'Cryptodome'

I solved the problem by installing the dependency:

pip install pycryptodomex

He is in requirements.txt, but I didn't see it installed when I installed the source library.
I am attaching a screenshot of the installation and error:

Only getting 651 error when using block scanner

I am using the block scanner with the LiteBalancer and getting 651 error when trying to call the raw_get_block_transactions_ext method for the block.

The code worked a few days ago (without any change) but now it's only returning 651 block is not applied
I think its because of a bad liteserver that is scoring high on the ranking of the LiteBalancer but have corrupted state.

What can I do about it?

Provide more examples

Provide examples of using LiteClient for:

Parsing blocks (using lookup_block, get_block_header, get_block and so on),
Accounts: get methods, account state, transactions
Config params
Additional suggestions are welcome!

connect_to_peer always timeouts

Trying to connect to specific peers on start. Tried public ones as well as own full node but connect_to_peer always timeouts.

I double checked the IP, port and the key and they are correct.

Is there any code or action or config needed to be able to connect with other node via adnl.connect_to_peer?

Without this, simple adnl.connect works fine, gets some peers connected automatically on start however after some minutes all peers disconnects. That's my second question: why does it happen and how to make sure the adnl is always connected (for example to my own node)?
