Any thoughts on this error?

The following is the output from the rustc --explain E0309 command

// This won't compile because T is not constrained, meaning the data
// stored in it is not guaranteed to last as long as the reference
struct Foo<'a, T> {
    foo: &'a T
}

This will compile, because it has the constraint on the type parameter:

struct Foo<'a, T: 'a> {
    foo: &'a T
}

To see why this is important, consider the case where T is itself a reference (e.g., T = &str). If we don't include the restriction that T: 'a, the following code would be perfectly legal:

struct Foo<'a, T> {
    foo: &'a T
}

fn main() {
    let v = "42".to_string();
    let f = Foo{foo: &v};
    drop(v);
    println!("{}", f.foo); // but we've already dropped v!
}

Could it be that you have an older Rust version? I think we require Rust 1.32 now.

The following command will tell you the version you have. If it's too old, try updating it with rustup.

rustc --version

[tpmccallum]

Thank you @Jannis I was using Rust 1.30 so I did the following to rectify (using Ubuntu 16.04)

# Remove old version
sudo apt remove rustc
# Install new version
curl https://sh.rustup.rs/ -sSf | sh

I once I had done this the cargo, rustc and rustup commands became available at the following file path

/home/ubuntu/.cargo/bin/cargo build

I have moved on to the next step ; step 7.

Now create the subgraph locally on The Graph Node with yarn create-subgraph. On The Graph Hosted service, creating the subgraph is done in the web broswer.

If I run the following command

yarn create-subgraph

in the uniswap-subgraph directory I get the following error

ubuntu@ip-1-2-3-4:/media/nvme/uniswap-subgraph$ yarn create-subgraph
yarn run v1.13.0
$ graph create uniswap-subgraph --node http://127.0.0.1:8020

Continuing without an access token 
Creating subgraph in Graph node: http://127.0.0.1:8020/
HTTP error creating the subgraph: ECONNREFUSED

[tpmccallum]

Solution for the above ^^^

I went ahead and created the following new server.js file inside the uniswap-subgraph directory, and then executed npm start followed by yarn create-subgraph.

var http = require('http');

http.createServer(function(request, response) {

    request.pipe(response);

}).listen(8020, '127.0.0.1');

console.log('Listening on port 8020...');

This seemed to allow for the subgraph to be created.

ubuntu@ip-172-31-12-226:/media/nvme/uniswap-subgraph$ yarn create-subgraph
yarn run v1.13.0
$ graph create uniswap-subgraph --node http://127.0.0.1:8020

Solution to the above ^^^

I went ahead and ran yarn upgrade and we have moved past the above error.

yarn upgrade

I now get the following message when running

yarn --verbose deploy --verbosity debug

I don't believe that the issue is with IPFS per se. Please read the Investigating Constructor options section below

Just FYI, I independently uploaded a file to IPFS using the command line.

# Create file
echo "This is a new file" >> test_ipfs.txt
# Upload file 
ipfs add -r test_ipfs.txt
added QmNZU5xtoEaHKiaJaDCWkTy3QB6pH6QdKHxZYCxLWmwk9R test_ipfs.txt

Check that the file exists

Investigating Constructor options

I started digging a bit deeper and traced the problem back the the "options" argument which is passed into the "Constructor" in the compiler.js file. Options is undefined :(

vi /media/nvme/uniswap-subgraph/node_modules/@graphprotocol/graph-cli/src/compiler.js

Logging the "options" looks like this

class Compiler {
  constructor(options) {
    this.options = options
    this.logger.note('Options are: ', JSON.stringify(options));

Results in the following message

TypeError: Cannot read property 'note' of undefined

From what I can see, the ./node_modules/@graphprotocol/graph-ts/tsconfig.json file extends the tsconfig.assembly.json file (as shown below).

{
  "extends": "./node_modules/assemblyscript/tsconfig.assembly.json",
  "include": ["index.ts"]
}

However the ./node_modules/assemblyscript/tsconfig.assembly.json file does not actually exist. I believe that this might be why the constructor options are undefined.

I can only see this file name once in the GitHub repo. Could this be part of the issue? https://github.com/graphprotocol/uniswap-subgraph/search?q=tsconfig&unscoped_q=tsconfig

What was the fix to this issue @davekaj?

[davekaj]

I dont think we ever solved it, and i closed it because the development of the uniswap subgraph is now in control of the uniswap team https://github.com/Uniswap/uniswap-v2-subgraph . i think it is likely that their subgraph should work when deployed!

https://github.com/Uniswap/uniswap-v3-subgraph worth looking at uniswap v3 as well
