singnet / snet-cli Goto Github PK

I would propose to support standard autocompletion pattern with tab.

For example:

• complete "snet co" after pressing tab to "snet contract"
• complete "snet contract M" after pressing tab to "snet contract MultiPartyEscrow"
• etc...

It should be a way to do it very easily since we are using standard argparse library. However I coudn't find a fast way to do it....

• More logs on success and error.
• Catching transactions exceptions.
• Fix and check if all possibles params are being updated.

This is a request to add -y option which answers yes by default on all questions without waiting from a user prompt

From what I can tell, the node and npm dependency is only needed to copy the contract json files from the singularitynet-alpha-blockchain package.

Is there some tooling from node/npm that we want to use, or would a cleaner alternative be to use a python script to download the contract files from a tagged release on github?

My understanding is also that npm is only needed for snet-cli development as the contract json files get bundled in the python package. Thus most users won't need node installed and it could be removed from the documented requirements?

When installing the snet-cli it requires libusb and libudev as dependencies. I would be best if that is mentioned in the README file .

GitHub warned me about this vulnerability when I created a Repo for testing snet-cli.

We found a potential security vulnerability in a repository for which you have been granted security alert access.

Prompt currently claims it expects the price in AGI, but it appears to actually be in 10 ** -8 AGI.

We had the following discussion on slack (https://snet.slack.com/messages/CCDKDJNUU/)
sergey:
(proposition 3: defining algorithm for sending transaction on "real" blockchain)
When we send transaction on real Ethereum network, even setting reasonable gas-price (from gasstation), we cannot be sure that transaction will be accepted in given amount of time, or will be accepted at all. Maybe there is an ICO now, or cryptokitties again. Actually I had such expirience few days ago playing with my ethereum account. So our automatic procedure for sending transaction might be as following:

• send transaction with reasonable gas price (probably check gasstation before)
• If transaction has not been accepted in, for example, 5 minutes, increase gas price and send it again (maybe recheck gasstation).
• Continue increasing gas price till given maximal value.
• If transaction with maximal gas price has not been accepted in 20 minutes send a warning to the owner with proposition manually increase maximal gas price.
• Wait and maybe do some predefined actions for suspending the system (on the server side)..
  Maybe there is a standard procedure already?
  cassio:
  On the final proposition: yeah, we should research possible existing solutions, but if we don’t find any we should write our own along the lines of your heuristic.

We need the following functionality

1. "simple" on-chain calls to MultiPartyEscrow contract (MPE)

• We need the possibility to call the following function: deposit, withdraw, openChannel, channelExtendAndAddFunds, channelClaimTimeout (in general, all public functions, except channelClaim, because it is a special case)

2. off-chain calls by behalf of the client.

• The function to call the server using existing channel.

3. on-chain call by behalf of the "treasurer-server"
   We need to implement the protocol of close/reopen which will be called by behalf of treasurer-server.

• Send to the daemons request to stop using old channel and switch to the new one (change the nonce of the channel)
• Wait from the daemons the last state of the old channel
• Make on-chain call to close/reopen the channel (using the last state obtained from the daemons): MPE.claimChannel

with general development plan.

Input a list of tags for your service, space separated: (default: [])

Error: 'list' object has no attribute'read'

I assume the the default value is being provided as a list, and the parsing code is attempting to read this.

As mentioned on Slack, the folder name model/ could cause confusion with trained NN models of a Service.

See discussion: #55 (comment)

Current snet-cli implementation allows to print both log messages and errors into std err or nothing.
It would be useful to add a debug level so it allows to print only error messages or both error and log messages.

Steps to reproduce:

• Go to the example-service project
• Run in command line:
  snet service init
• For the choice 'Choose the path to your service's spec directory: (default: "service_spec/")' type . (current directory, this allows to resolve the provided path)
• Use snet to publish the local config
  -Run example-service with snet-daemon
• Execute snet client call classify

The error 'ERROR: failed to retrieve service spec' is not printed.

We should check hash of files from IPFS. Otherwise we can be attacked if ipfs client is compromised.
Function which read IPFS is here:

There are several design choices for how service authors interact with the CLI that I think could be improved. Publishing a service requires individual steps and keeping track of a global state which results in having to track the agent address manually. See discussion on singnet/wiki#16

This is a proposal for a substantial refactor of the interface, but to only be worked on once the core SNet behaviour has been built and stabilized. Discussion is welcome!

Local state

Instead of tracking config related to snet-cli globally, and dumping different json files in different locations, we should keep all SNet related files together.

e.g. inside a service directory, we could have a structure like:

• .snet\service.json
• .snet\daemon.json
• .snet\[other?] - should compiled protobuf files go here too?

The daemon and CLI could then read the information they need from this local context if it exists.

Motivation:

• the daemon wouldn't require a user to specify where the config file is, and the user wouldn't have to separately create it. All this information could be generated as part of creating a service.
• the current_agent_at and other current_ state variables are not a useful pattern to service authors. It's hard to remember what the current identity, network, and agent address all are set to. All of these could be stored in service.json meaning the user doesn't have to remember anything... they just have to be in the right directory.

In addition, like git, if there is no .snet directory, our tools should walk to parent directories until a .snet directory is found and use that.

Commands

Ideally, once a user has configured the CLI (with identity, network), then there should only be two core
commands. We could call these different things, but I think following git subcommand names will mean less cognitive demand of new users:

• init - create a new service in the current directory. This should also generate template proto files for the interface definition, unless they already exist. This doesn't push anything to blockchain or IPFS.
• push - this command should automagically figure out if it needs to create/modify contracts or publish changes to IPFS. So the first time you run it it will create a new agent - possibly with a warning/confirmation. Later it will only do something if you've changed the config somehow.

Beyond that, in the future I could see these to commands being useful:

• run/develop
  • First regenerate proto/grpc related code if proto files have changed.
  • Then run a local server (the command to run the user's service should be in the local config) and the SNet daemon. This removes the need for service authors to create their own scripts that launch and monitor these two processes.
  • run would provide a functional server that could be production ready (for simple services that don't have complex architecture)
  • develop would have additional debugging abilities, including hosting a webserver that would show a simple version of what the dapp provides. This would allow users to easily debug and test their UI layout locally.
• deploy - when we have SNet infrastructure, this would deploy the current service to our (or another) cloud service.

Documentation and Metadata

There is a field in metadata for a description of the service. This is nice, but
it'd be great to make it really easy to publish markdown descriptions. These could then be rendered nicely in a dapp).

Rather than putting this documentation in a json value (urgh!!), we could allow the user to place it as a markdown file inside the services .snet directory. This would automatically be bundled and published to IPFS. Down the road we might want to allow more complex documentation structures e.g. an entire directory of documentation that can be fetched by service clients and browsed locally. If we want a decentralised developer network, then this is a better option than relying on github or other external websites for decent documentation.

Summary

I know there is a lot of work before we get to this point, but I wanted to describe it here because I think aiming for a developer experience like this would make SNet really pleasant to use.

But please let me know if you think otherwise!

singnet/alpha-dapp#8

As I understand, one can use the same identity on multiple networks, but from the view of good security practice I wouldn't want to be using my mainnet identity on kovan. It would be too easy to accidentally use real ETH instead of KETH.

Would it make sense to allow the user to specify a network when creating an identity? Then when that identity is selected, the correct network could automatically be updated for the current session.

You could still allow no network to be specified. In that case, when an identity with no network is selected, a warning could be shown. This would remind the user that they may want to change the network manually.

I'm trying to publish one of the face-services.

All the face-services rely on a shared protobuf definition file face_common.proto.

When I try to publish the face detection service, I get this error:

$ snet service publish
Error: Import path must be a valid file: /home/joel/work/services/face-services/services/grpc/services/grpc/face_common.proto

This error is correct, there is no file at that location. It is duplicating the services/grpc part of the path.

However, whatever I try, I can't get it to use the correct path for the import.

I have tried:

• changing the import statement in face_detect.proto to use a relative path to the file being processed
• a relative path to the current working directory
• ensuring face_common.proto in the same directory as face_detect.proto and using no path prefix: import "face_common.proto";

What ever I try, it always adds the prefix services/grpc twice instead of once.

The reason sharing a common definition is important is that then APIs will rely on consistent primitive message types. Without this, every API is essentially independent and application developers will have to spend all their time converting between types when relying on multiple SNet services.

Command line length is limited in different ways depending on one's OS.

base64 encoding of images or other binary data results in a potentially very large input string which makes it impossible to send reasonable size images on a default Windows set up (but even linux/osx have limits!).

Making a client call should allow the parameters to be read from a file, or ideally read from stdin.

I'm happy to implement this tomorrow unless people object to this approach, or have a strong desire to do it themselves :-) (I need it for testing face-services)

If you publish a service using a service.json and then publish it again with different name a new service will be published at the same Contract Address.

We should alert users (with a warning message), avoiding wrong publications.

To reproduce:

$ snet set current_agent_at 0x1e89d9ed5bcc22f934af631cda771019081e57b2
set current_agent_at 0x1e89d9ed5bcc22f934af631cda771019081e57b2

Then running snet client call [method] [json], I got this:

...
File "/usr/local/lib/python3.6/dist-packages/web3/utils/validation.py", line 123, in validate_address
    value,
web3.exceptions.InvalidAddress: ('Web3.py only accepts checksum addresses. The software that gave you this non-checksum address should be considered unsafe, please file it as a bug on their platform. Try using an ENS name instead. Or, if you must accept lower safety, use Web3.toChecksumAddress(lower_case_address).', '0x1e89d9ed5bcc22f934af631cda771019081e57b2')

But getting the address from etherscan (0x1E89D9ed5bCC22F934AF631CdA771019081E57B2), it works.

Question is...should we use this lower safety function or just warn user to change address format?

There are python libraries to work with dynamic loading of modules, e.g. https://stackoverflow.com/a/19393328/272238

Here we claim we can't use this approach, but it is unclear why.

Given python has a lot of tools for runtime introspection, and the risks with exec/eval I'd like to understand what the limitation is that forces us to use them.

We should replace all "ugly" ContractCommand calls with call_contract_command or transact_contract_command functions which will be introduced with #77.
For example

agent_contract_def = get_contract_def("Agent")
        price = ContractCommand(
            config=self.config,
            args=self.get_contract_argser(
                contract_address=agent_address,
                contract_function="currentPrice",
                contract_def=agent_contract_def)(),
            out_f=None,
            err_f=None,
            w3=self.w3,
            ident=self.ident).call()

Can be replaced with

self.call_contract_command("Agent", agent_address, "currentPrice", [])

I run the command where 'snet mpe-client call_server' where some arguments are not correct.
Something like:
snet mpe-client call_server 0x5c7a4290f6f8ff64c69eeffdfafc8644a4ec3a4e 0 10 localhost:8080 "\"Addition"\" add '{"a":10,"b":32}'

snet prints the error from the service but does not fail the process:

unspent_amount before call (None means that we cannot get it now):420000
Error: Critial Error. ""Addition"" is not an identifier
If you want to see full Traceback then run:
snet --print-traceback [parameters]

See for example CircleCI output: https://circleci.com/gh/stellarspot/platform-pipeline/91

This part of code runs only if "dest_dir" doesn't exist.

• Create a high level interaction with Registry to delete a service.

Depends on issue singnet/snet-daemon#99

At the moment state_service.proto is hardcoded to the snet-cli sources (see commit 01b83dbcf587d7c7ab7f7c01ba52d4b8a22dce8c). snet-cli should get this file from snet-daemon release artifact.

@astroseger as discussed yesterday, creating issues for open items

The config file is created with open read permission to anyone.

This is also where private keys are stored.

$ ls ~/.snet/config
-rw-rw-r-- 1 joel joel 483 Aug 14 16:40 /home/joel/.snet/config

Fix is to create the file with correct permissions (read permissions only available to owner), then write the ConfigParser to it, inside the persist function.

I think it's very handful for an user to be able to check the installed version of snet-cli from command line.

Like this (avoiding use -v for use it with --verbose in the future):

$ snet
...
SingularityNET CLI

optional arguments:
  -h, --help         show this help message and exit
  -V, --version      show version and exit
...

To create a personal org, I need to do:

snet organization create joel MY_ADDRESS

But snet already has my identity, so I wonder if it should be sufficient to just do:

snet organization create joel

I'm also unclear who the owner of the organisation is if I specify a different address. Since I'm making the transaction, am I automatically the owner? Or is that role granted upon the initial members?

If I'm automatically the owner, then I think having an empty member list should be possible.

Checking on one's balance is probably a common enough use case that it'd be nice to make it easy for people via a single command.

Currently the two pieces of information can be obtained by the contract command:

snet contract SingularityNetToken balanceOf MY_ADDRESS

And the python code:

from web3 import Web3, HTTPProvider
w3 = Web3(HTTPProvider("https://kovan.infura.io"))
w3.eth.getBalance(MY_ADDRESS)

Both of these return large integers, without a decimal point delimiting the whole currency amount. ETH and AGI also have different decimal point positions.

To avoid making the user think, they should by default be converted to AGI and ETH. (e.g. instead of showing 2657719035000000000, it should show 2.6577 ETH or some other number of significant figures)

Currently CLI supports publishing service models as a service developer, but doesn't support pulling models as a consumer.

CLI should have the ability to generate client stubs for calling SingularityNET AI Services in a variety of supported programming languages

Depends on #28

When we publish a service, we are given an agent address.

The address is used to configure the daemon.

So the daemon won't be running until after the service is published.

Thus hitting the endpoint during the publish command seems unnecessary (unless there is already a valid agent address, and publish is just updating the endpoint).

• Service with plain text instead of protobuf (.proto) file.
  • Service with ~1Mb file:
    -rw-rw-r-- 1 artur artur 1013076 Set 17 17:04 NOT_PROTO_FILE_1MB.proto
  • But not with > 1.5Mb file:
    -rw-rw-r-- 1 artur artur 1475526 Set 17 16:59 NOT_PROTO_FILE_1_5MB.proto

This doesn't make sense and there currently is this entry in the registry:

NovelSoftwareSystems/CellCouner | 0xa5c9...e9f1 | 1e-8 AGI | http://192.168.1.199:5000

Local network addresses should be limited to private ethereum nets, not published on kovan or mainnet.

The IP blocks that should be tested for are here: https://en.wikipedia.org/wiki/Private_network#Private_IPv4_addresses
