When using websockets, the simulator was starting on port `8545` instead of `8546`, so the blockchain check was failing.
Update the simulator port to be websockets port from the config when using websockets.
When whisper was being started in a new process, the message displayed in the console was “Starting Blockchain node in another process”. This is misleading as it is the same message that geth/parity use to start up their processes.
Update whisper initialisation process messaging so it states “Starting Whisper node in another process”.
Improve the reliability of the expiration unit test in the test dapp by explicitly setting the `block.timestamp` and comparing an expiration value against that.
This improves on the current implementation that relies on time passed which varies depending on the speed of unit tests run (CPU speed, logs shown, etc).
When `eth_unsubscribe` is received in the proxy, ensure this request is forwarded through on the correct socket (the same socket that was used for the corresponding `eth_subscribe`).
Move subscription handling for `eth_subscribe` and `eth_unsubscribe` to RpcModifiers (in `rpc-manager` package).
For each `eth_subscribe` request, a new `RequestManager` is created. Since the endpoint property on the proxy class was updated to be a provider, the same provider was being assigned to each new `RequestManager` and thus creating multiple event handlers for each subscription created. To circumvent this, we are now creating a new provider for each `RequestManager`.

This PR adds support for EIP-712 (https://github.com/ethereum/EIPs/blob/master/EIPS/eip-712.md), by allowing the signing of typed data transactions using the `eth_signTypeData_v3` or `eth_signTypedData` request.
Add a module called `embark-rpc-manager` to handle all RPC transaction modifications.
The internal events management module extracted to `embark-core`. This allows other modules (ie plugins) to use a private instance of Embark’s event API.
Remove transaction modifications in `embark-accounts-manager` and leave only the functionality in this module that handle account management (ie funding of accounts). Other functionality was moved to `embark-rpc-manager`.
- Transactions should now reflect when a new node account is added via `personal_newAccount` or via the node itself (and once `eth_accounts` is requested).
- In the proxy, errors are handled for all cases and are now JSON-RPC spec-compliant.
- Always register `eth_signTypedData` RPC response and display error message if account cannot be found.
NOTE: Updated yarn.lock due to conflict after rebase.
Avoid race condition with rpc modifications
Refactor proxy to make request handling asynchronous, and to allow circumvention of forwarding requests to the node in cases where it is not needed.
Move loading of plugins to after core and stack components (in cmd_controller).
We should load custom plugins LAST (ie after all core and stack components, and after all Embark plugins). To do this, we disable automatic loading of plugins in the config, and allow them to be loading explicitly in cmd_controller.
Create a system that allows registration of custom plugins. Each plugin is generated in EmbarkJS by instantiating the registered class. For example, we can register a Plasma plugin and it will be generated in to EmbarkJS.Plasma with an instantiation of `embarkjs-plasma`. The DApp itself can then do what it wants with `EmbarkJS.Plasma` (ie call `EmbarkJS.Plasma.init()`.
NOTE: loading of custom plugins needs to be applied to all other commands in `cmd_controller`. This PR only loads custom plugins for the `run` command.
NOTE: This PR is based on branch fix/ws-eth-subscribe (#1850). I will rebase this PR when (and if) #1850 is merged.
In 776db1b7f7 (diff-5cab125016e6d753f03b6cd0241d5ebbR267) we've introduced the ability to add
a `priority` parameter to plugin actions, so the order of actions can be semi-ensured.
That commit also introduced typings for that new API but it actually didn't match the
implementation of the API, namely that the second parameter of `Plugin.registerActionForEvent()`
can be either an options object **or** a callback function.
This forces consumers to call the API as `registerActoniForEvent(name, undefined|null, callback)`
which shouldn't be necessary.
BREAKING CHANGE:
Related to #1985. Prior to Embark's minimum supported version of Node.js being
bumped to to 10.17.0, Embark was incompatible with any relatively recent
release of the `ipfs-http-client` package.
While *internal* changes are needed re: ipfs's `Buffer` export for
e.g. `embark_demo` to function correctly *(and this PR makes those changes)*,
Embark otherwise runs/tests okay.
Keep in mind #2033.
However, if a dApp author were to explicitly `require('ifps-api')` in the
front-end that wouldn't work as before; and swapping `"ipfs-http-client"` for
`"ipfs-api"` might also not be enough — there are API changes that dApp authors
would need to consider, regardless of Embark presently supplying the dependency
and EmbarkJS wrapping around it.
Closes#1994.
Hook `embark-profiler` into the engine's contracts group.
Adjust `request` signatures to match v5 usage.
Ensure gas numbers are formatted consistently in the ascii table.
Display non-json output in cockpit's console as monospace/pre to preserve
profiler table formatting.
Embark's `File.content` is an asynchrononus getter that potentially downloads the
contents of a file from its `externalUrl`. This can potentially fail but is not properly
reported to the user as the error itself is ignored.
This commit ensures errors are propagated and displayed to the user.
The blockchain module should not contain any ethereum-specific code, and currently it contains a check to see if the blockchain has already been started.
This PR moves this check to blockchain client (ie geth or parity). This check function is registered along with the started callback.
style(@embark/stack/blockchain): add missing semicolon
Turns out that, when Embark tries to replace ENS subdomains, it would fail
if `subdomains` aren't defined in the namesystem configuration.
This commit adds a safeguard so that not defining `subdomains` is fine.
This commit fixes the issue that it wasn't possible anymore to use named constructor arguments
in Smart Contract configurations.
For example, the following Smart Contract expects two constructor arguments:
```solidity
contract SomeContract {
constructor(address[] _addresses, int initialValue) public {}
}
```
The first being a list of addresses, the second one a number. This can be configured as:
```js
SomeContract: {
args: [
["$MyToken2", "$SimpleStorage"],
123
]
}
```
Notice how the order of arguments matters here. `_addresses` come first in the constructor,
so they have to be defined first in the configuration as well.
Another way to configure this is using named arguments, which is what's broken prior to this commit:
```js
SomeContract: {
args: {
initialValue: 123,
_addresses: ["$MyToken2", "$SimpleStorage"]
}
}
```
Using a notation like this ^ the order no longer matters as Embark will figure out the right
values for the constructor arguments by their names.
The reason this is broken is because there are several modules in Embark that register and
run a `deployment:contract:beforeDeploy` action, which are allowed to mutate this configuration
object. One of those modules is the `ens` module, which searches for ENS names in the arguments
and figure out whether it has to replace it with a resolved address.
One thing that particular module didn't take into account is that `args` could be either and
array, or an object and will always return an array, changing the shape of `args` in case it was
an object.
This is a problem because another module, `ethereum-blockchain-client`, another action is registered
that takes this mutated object in `determineArguments()` and ensure that, if `args` is actually an
object, the values are put in the correct position matching the constructor of the Smart Contract in
question.
One way to solve this was to use the newly introduced [priority](https://github.com/embark-framework/embark/pull/2031) and ensure
that `ens` action is executed after `ethereum-blockchain-client`'s.
However, the actual bug here is that the ENS module changes the shape of `args` in the first place,
so this commit ensures that it preserves it.
Update event name `"deploy:contract:deployed"` to
`"deployment:contract:deployed"`.
Also, listen one time for `"deployment:deployContracts:afterAll"` and then
request the full contracts list so as to pickup contract names that were
already deployed. This is necessary for subsequent `embark run` (without
reset), otherwise the suggestions list will be missing contracts.
The `WhisperGethClient` returns empty strings for its "new account" and "list
accounts" commands; if a command is an empty string then `Blockchain` should
not execute it.
Previously, in the embark cli dashboard/console, if you were to type `Foo.` and
hit tab for autocomplete then (assuming you hadn't defined `Foo`) there would
be unhandled errors and the console could even become unusable.
Refactor `packages/core/console` and related code so that nothing happens when
you attempt to autocomplete a bad reference (the same behavior as Node's own
REPL).
Also bump peerDeps: @emotion/core from 0.13.1 to 10.0.22 and @emotion/styled
from 0.10.6 to 10.0.23. Satisfy @babel/runtime peerDep with 7.6.3.
Make small refactors in components/FileExplorer and
containers/FileExplorerRowContainer re: the package upgrades.

`embark console` registers and tries to spin up `Cockpit`, even when there's already
a Cockpit instance running and thefore exits with an error that a certain port is already
in use.
This commit ensures that Cockpit is only bootstrapped when `embark console` is
executed as a non-secondary process, meaning that there's no other `embark run`
process active that might occupy Cockpit's default port.
We've introduced a regression in https://github.com/embark-framework/embark/commit/f9557d4c9 where invalid data
has been sent to web3's `ecRecover()` method to verify signed messages.
This causes an internal server error and the utility feature inside Cockpit
unsuable.
This commit ensures that the correct data is sent to `ecRecover()` making verifying
messages through Cockpit functional again.
Fix the proxy’s handling of WebSocket connections when subscribing to contract events and node data using the `eth_subscribe` RPC request.
Previously, the client connection that the subscription data was sent to was often in a closed state. It was determined that this connection was the wrong connection to forward the data in the first place. The connection was in fact generally the connection created for the Ethereum service check which was then (correctly and subsequently) closed after it had finished its operation.
The flow of a proxy request handling a WebSocket “eth_subscribe” RPC request is now as follows:
1. A WebSocket RPC request `”eth_subscribe”` is sent from a client to the proxy.
2. Proxy forwards the request to the node by way of a new instance of `RequestManager`.
3. When the node receives an event matching the subscription, it sends the event data back to same socket connection it received the request on (ie the specific instance of `RequestManager`).
4. The `RequestManager` fires the `”data”` event containing the subscription data, and this event is picked up in the proxy.
5. The proxy then forwards the subscription data on to the originating WS client connection.
All other requests (ie non-WS or WS RPC requests that are not `eth_subscribe`) will be serviced to/from the node using a single `RequestManager` instance.

Running embark's `blockchain` command resulted in a runtime error where the `blockchain`
module couldn't be found. This is a bug introduced in ed0d3afb4f where
we forgot to update `blockchainStackComponents` in Embark's engine accordingly.
Fixing this results in `embark blockchain` hanging. This is because there's a similar bug
in `blockchainStackCopmnonents` introduced in 3b8f8f9ea7.
This commit fixes both bugs by ensuring `embark-blockchain` and `embark-blockchain-client`
packages are loaded using the correct APIs.
If the version in the embark package's own `package.json` has a prerelease
identifier then appending `.x` to the major version isn't viable for resolving
the latest version of the template package that's in the same prerelease line;
a more complex semver range must be used:
```
"${pkg}@^${major}.${minor}.${patch}- <${major}.${minor}.${patch}"
```
When making use of the `useBuiltIns: 'usage'` option for @babel/preset-env
(which is the case for all transpiled packages in Embark's monorepo) a package
needs to have both @babel/runtime-corejs3 and core-js@3 specified as
dependencies.
Embark relies on certain specific plugin properties, e.g. registered compilers,
and retrieves them using `plugins.getPluginProperties('compilers', 'compilers')`.
In order to make this work in the testing environment, we need those same APIs
in the `embark-testing` package as well.
This commit adds necessary APIs to `Plugins` and `Plugin` to make registering and
loading compiler plugins work.

Also get rid of a peer dependency warning related to storybook. After some

to just satisfy all of them explicitly, which in any case won't interfere with
CRA (react-scripts).

BREAKING CHANGE:
node: >=10.17.0 <12.0.0
npm: >=6.11.3
yarn: >=1.19.1
node v10.17.0 is the latest in the 10.x series and is still in the Active LTS
lifecycle. Embark is still not compatible with node's 12.x and 13.x
series (because of some dependencies), otherwise it would probably make sense
to bump our minimum supported node version all the way to the most recent 12.x
release.
npm v6.11.3 is the version that's bundled with node v10.17.0.
yarn v1.19.1 is the most recent version as of the time node v10.17.0 was
released.

**NOTE:** Please merge https://github.com/embark-framework/embark/pull/1950 first before merging this PR, as this PR contains removal of dependencies from `packages/embark` that are needed for geth. So if this is merged first, and the geth PR (https://github.com/embark-framework/embark/pull/1950) is not merged, then geth will not have some of the dependencies it needs.
**NOTE:** Running a dapp with `client: “vm”` does not work, however I am not sure if that is intentional in v5 or not.
**NOTE:** Running `embark test` in the demo DApp does work, although there is an error that I am assuming does actually pertain to this PR:

**TODO:** The `embark eject-webpack` command needs to be updated. @michaelsbradleyjr - do you have suggestions as to how we could port this over? We could **assume** that the `basic-pipeline` plugin will be installed, and then read the embark config and overrides from the file system, however this feels like we are sort adding a dependency to a plugin, which is not right. Any suggestions?

It's principal use was in `stack/compiler`, but that package was refactored
in #1878 to use async/await. There was a replica in
`packages/embark/src/lib/utils/async_extend.js` but it wasn't being used to do
async operations and could be replaced with `Object.entries().forEach()`. It
was required by `plugins/vyper` but the wrapper's custom `eachObject` method
wasn't being used. `stack/api` had it as a dependency but wasn't using it.

This commit introduces a new Smart Contract configuration addressHandler
that lets users define a function to "lazily" compute the address of the
Smart Contract in question.
This is useful when a third-party takes care of deploying a dependency
Smart Contract, but the address of that Smart Contract only being available
at run-time.
Example:
```
deploy: {
SimpleStorage: {
fromIndex: 0,
args: [100],
},
OtherContract: {
deps: ['SimpleStorage'],
address: async (deps) => {
// use `deps.contracts.SimpleStorage` to determine address
},
abiDefinition: ABI
},
}
```
In the example above, OtherContract will be deployed after SimpleStorage
because it uses the deps property to define Smart Contracts that it depends
on. All dependencies are exposed on the addressHandler function parameter
similar to deployment hooks.
Closes#1690
There was an error that would display on the second+ run of embark, that was causing by trying to read JSON of an empty file.
The solution was a combination of ensuring the file existed with defaults when enabled, and also ensuring we await the saving of the file.
Included is a bit of a refactor of how the tracking functions handled the “current chain”. Hopefully, this should make things more clear.
Tests have been updated accordingly.

* use generate:all instea dof the event
This is crucial as the storage module tries to generate/eval artifacts that
depend on a `web3` object inside the VM scope. The registration of that object
can only be garuanteed when the `blockchain:started` event has been fired.
This commit ensures these modules are not spinned up in parallel as we're running
into race conditions.
DApps generated with `new --simple` don't have a blockchain config so ensure
that the blockchain proxy and listener (dev_txs) use appropriate provider
settings when setting up web3.
Without these changes, in a fresh `embark new --simple` project the `embark
blockchain` command will encounter unhandled promise rejection with respect to
the proxy; `embark run` will encounter similar with respect to dev_txs.
Previously, when using "development embark" (i.e. `embark` command in the
monorepo) the template generator would always use `yarn install` to install a
template's dependencies. However, if a template relies on `package-lock.json`,
as is the case for `embark-create-react-dapp-template`, that behvaior can cause
serious problems. So, have the choice of install command depend not only on
whether we're using "development embark" but also whether the template has a
`package-lock.json` file.
NOTE: this change can probably result in problems given that `yarn install` and
`npm install` behave differently re: symlinks in `node_modules`. However, such
problems would never show up with production installs of the `embark`
packaage. Moreover, after dropping `embarkjs-connector-web3` we don't presently
have a situation where a monorepo package would be `yarn link`ed into an
instantiated template's `node_modules`. So, in effect, the changes introduced
in this PR allow existing templates to work correctly whether using production
or monorepo embark. The impending embark v5 refactor should deprecate `embark
new` in favor of the yet unfinished `embark init`.
When passing the name of a build pipeline that doesn't exist, e.g.
`embark run|build --pipeline foo`, `writeStats` would cause an unhandled
promise rejection because its config argument is falsy. Checking for that and
returning early from `writeStats` allows the `"no webpack config has the name
'foo'"` error to be reported correctly.
The ignore paths for the default webpack config and babel-loader-overrides
helper script weren't properly adjusted after the legacy pipeline was split-out
into its own package in the monorepo.
Upgrade all dependencies on web3/web3-* v1.0.0-beta.37 to v1.2.1.
Make various adjustments related to the previous convention of
`"web3": "1.0.0-beta"` in `embark.json` signifying that embark's own web3
dependency should be used in dapp builds.
Fix bugs in library manager, including a switch from using the
live-plugin-manager package to using npm in a child process to install
`"versions"` dependencies specified in `embark.json` when a specified version
doesn't match up with embark's own version for that package.
Avoid race conditions when installing `"versions"` by completing all installs
prior to starting other services. If an install fails, then after all the
installs have completed or failed the embark command will exit with error.
Change various comments and update docs to reflect the new default of web3
v1.2.1.
In https://github.com/embark-framework/embark/commit/87d92b6091 we've introduced a feature in our test runner
to report exact gas costs used when calling Smart Contract methods that
cause computation.
Embark keeps a list of deployed contracts in memory and for all transactions
happening during tests, it'll match them to the contracts that performed them
to produce the report logs.
Unfortunately, we've been [resetting that memory](https://github.com/embark-framework/embark/commit/87d92b6091#diff-92b4f79a0473160fe700440b1ced5204R140) of deployed contracts
after every test, making it practically impossible for Embark to find
matching contracts for any transactions, because contracts aren't necessarily
redeployed per spec, resulting in no additional transaction logs whatsoever.
This commit ensures that the memory is never erased and at the same time
ensures it's not leaking infinitely in case multiple contracts are
deployed multiple times in the same process over several specs.
We've introduced a regression in 536a4029ba where the default
`value` sent to payable Smart Contract methods is `-1`, resulting in errors as it's not
a valid value.
For payable methods inside of the contract interatction section of cockpit, the value input has been updated to pass wei to the API. The input field now accepts value like `100 ether` or 25 szabo`. The value entered is automatically converted to wei and shown to the user in real time.
Additionally, the input is validated for a correct value, with an error shown to the user for incorrectly entered values.
A tooltip has been added to help the user enter correct values.
UI updates can be seen in video here: https://monosnap.com/file/642cHH2HxDeiFLzB2VLqHP9GuqoRfz
This is due to a bug that has been introduced in d10c0b7951 where we end up
sending values as numbers to web3's `toWei()` utility. The `value` is always sent as number
and in fact always defined, so we just need to check for it's type and convert it to a string
according to `toWei()`'s API.
When running tests against non-simulated blockchain nodes, even for simplex
Smart Contracts, deployment transactions would exceed the block gas limit.
E.g. running `embark blockchain` in one process and `embark test --node embark`
in another, inside our demo application, will throw an error when Embark attempts
to deploy its `SimpleStorage`:
```
Compiling contracts
Compilation done
[SimpleStorage]: error deploying =SimpleStorage= due to error: Returned error: exceeds block gas limit
Error deploying contracts. Please fix errors to continue.
Error deploying contracts. Please fix errors to continue.
terminating due to error
Error deploying contracts. Please fix errors to continue.
```
The reason for that is because in https://github.com/embark-framework/embark/pull/1650, we've introduced a static
gas estimation for Smart Contract deployment that is just right below Ganache's
maximum gas limit of `6721975`, since Ganache tends to underestimate gas for
complex Smart Contracts due to its [low base fee](8ad1ab29de/lib/utils/gasEstimation.js (L33-L39)).
The static gas estimation would apply any time we're in a test context, but we
didn't take into account the case where tests are executed against nodes
other than the simulated environment.
As mentioned in the comments in the linked PR:
> If this is not spec'ed at all, I wonder what complications it could cause when
> at some point we maybe switch to not using Ganache anymore for tests, or even
> the user itself (which I think is a reasonable thing to do).
This causes the error described above because we easily reach the block gas limit
with just two Smart Contracts and Embark already deploys a few Smart Contracts for
ENS.
So basically what we want is to use the static gas estimation when we know
the node we're connecting to is Ganache. In all other cases we can rely on the
standardized gas estimation offered by the node.
Adjust the API endpoints to augment transaction objects with a timestamp
property from their corresponding blocks. This removes the necessity to copy
the timestamp property from a block to its transactions in the client.
Introduce a `formatTimestampForDisplay` util function in Cockpit for
consistently transforming timestamps into relative or absolute dates, depending
on whether a date is sometime during the last day.
The property is set/available on EmbarkJS in the artifacts, i.e. in a browser
build; but sometime since v3.2.4 it was no longer availble in the cli dashboard
environment.
`EmbarkJS.Messages.isAvailable()` in some cases return synchronously (when whisper isn't
set up), in other cases asynchronously. This actually breaks our demo application for
the following reason:
We check for Whisper's availability via:
```
EmbarkJS.Messages.Providers.whisper.getWhisperVersion((err, _version) => {
if (err) {
return console.log(err);
}
this.setState({whisperEnabled: true});
});
```
There's a couple of problems here:
- This code will break right away when whisper isn't available, resulting in an error:
```
Cannot read property _requestManager of undefined
```
- The reason this error happens is because there's no `web3` object available inside
our EmbarkJS.Messages code. Even though there **is** a web3 object, EmbarkJS.Messages
doesn't know about this because it only sets it when its `setProvider()` API is called,
which effectively doesn't happen at all when Whisper isn't enabled on the connected
node
- While this could be fixed with a simple check on whether EmbarkJS.Messages' internal
`web3` references is a thing, really what should be used in the demo is the `isAvailable()`
API.
`isAvailable()` should always return a promise (similar to `EmbarkJS.Storage.isAvailable()`.
This commit ensures that `isAvailable()` always returns a promise and changes the demo
template to use `isAvailable()` over `getWhisperVersion()`.
Effectively deprecate the `embarkjs-connector-web3` package but don't introduce
a breaking change by simply not loading the plugin if it's specified in a
DApp's `embark.json`. If the deprecated plugin is specified, display a message
indicating the plugin was ignored and suggesting it be removed from the
project's `embark.json` and `package.json`.
This PR adds a command to get full account details from the contradts config that includes info like private key.
The existing, and similar command, `blockchain:provider:contract:accounts:get` would only return account addresses if they existed, and not the full account info.
This check was already made when sending messages to whisper channel, however, we didn't
perform the same check when subscribing to channels within cockpit.
The webserver's job is to serve files generated by Embark's built-in pipeline,
however, since v4 users can choose they front-end tool to take care of building,
bundling and packing their DApps. Usually these tools come with a built-in
dev server as well.
Therefore, when the pipeline is turned off (which also soon will be the default),
there's not need start a webserver.
In https://github.com/embark-framework/embark/pull/1119 we've introduced a feature where
users can provide an already compiled ABI for Smart Contracts so they can be used
without the need to compiling them again.
This also means that, internally, those Smart Contract object won't have any
bytecode attached to it.
Later on, in 387d33a076, we've introduced a warning
which is rendered when a Smart Contract's bytecode is too large. The check expects
a Smart Contract object to have bytecode associated to it, which will break the code
in cases where a Smart Contract has already an ABI and therefore didn't need compilation.
This commit ensures we only check a Smart Contract's bytecode when bytecode exists for
the Smart Contract in question.
When trying to either sending, or listening to whisper channels within
Embark's consoles (CLI and Cockpit), the console outputs an error that
`EmbarkJS` isn't defined.
E.g. running:
```
> EmbarkJS.Messages.listenTo({ topic: ['somechannel'])
```
Outputs:
```
EmbarkJS is not defined
```
This seemed very odd as outputting `EmbarkJS` and all of its members
worked totally fine.
It turns out that both methods, `listenTo()` and `sendMessage()`, in
`EmbarkJS.Messages` are not necessarily what one thinks they are.
EmbarkJS decorates both methods to create some options that need to be
available in the delegate, two of them being `EmbarkJS.Utils.toAscii`
and `EmbarkJS.Utils.fromAscii` (ac76a40a61/packages/embarkjs-whisper/src/index.js (L43-L62) and ac76a40a61/packages/embarkjs-whisper/src/index.js (L64-L73))
These two global references to `EmbarkJS` are the only ones in `embarkjs-whisper`
and they are not the same reference as the `EmbarkJS` sandbox global
registered in the VM here ac76a40a61/packages/embark-code-runner/src/index.ts (L33).
In other words, the `EmbarkJS is not defined` message actually refers
to the `EmbarkJS` in the wrapping method, not the one registered with
the VM, which is also why inspecting the `EmbarkJS` object through the
VM works fine.
Since the `toAscii()` and `fromAscii()` methods in use are really just
facades around `web3.utils.[fromAscii|toAscii]()`, we can replace the
global EmbarkJS dependency with web3 utils that are already available
anyways.
Upgrade chokidar to a version that's compatible with NodeJS v12.x.
Unfortunately, embark has other transitive dependencies that are not compatible
with v12.x, but upgrading chokidar is still a good step.
When running unit tests inside a project that configures ENS subdomains using Smart Contract directives,
the tests will output an error because of that particular Smart Contract's `deployedAddress` being `undefined`.
This happens only when running tests, not when deploying the Smart Contracts including the custom ENS setup.
It turns out that Embark attempts to compile and deploy the Smart Contracts of the project *twice* - once
before tests are executed, and another time **after** tests are done executing.
Both compilations/deployments are triggered through our custom `config()` function within test context,
which ensures all Smart Contracts are deployed before tests are executed.
This explains a few things:
1. There's no such issue when running `embark run`, in fact the custom ENS subdomains work perfectly fine
2. That's also why the tests are passing fine as well as the first compilation/deployment doesn't have any issues.
The errors only appear *after* the tests have been executed.
Still, this raises a few more questions, mainly
- Why is the Smart Contract's `deployedAddress` property `undefined` when `config()` is executed a second time?
- Why is `config()` executed a second time in the first place?
Let's look into both of these.
Assuming that there's a valid reason that `config()` is called twice, it's remains unclear why that property
of a Smart Contract object is `undefined` in the second run. The reason for that is that Embark determines whether
or not a particular Smart Contract should be deployed. One of the routines ensures that only the Smart Contracts
configured for deployment are actually attempted to be deployed (as opposed to just deploying all Smart Contracts
found in the file system).
It turns out that the second `config()` call is done without any Smart Contract configuration, resulting basically in no deployment
for any Smart Contract of the application. The `address` and `deployedAddress` of a Smart Contract object are however only set
*after* deployment, resulting in them being `undefined`.
**All this makes sense.**
`config()` is simply not designed for being used with an empty `contracts: {}` config. This raises another question:
Why is `config()` called with an empty configuration? This leads us to the second point.
It does seem a bit weird that Embark tries to configure compile *and* deploy a DApp's Smart Contracts again right **after**
the tests have been executed. So why is that?
A quick `git blame` (no blame intended here) shows us that this routine has been introduced in https://github.com/embark-framework/embark/commit/12cbb7bdd.
Notice the second list point of the commit:
> Contracts that had been compiled in the JS tests were being deleted at the end of the JS test run, which caused errors
> with the files not being found. The fix was to reset the contracts config to no longer require the non-test contracts
> to be compiled/deployed.
The above is a little tricky to understand without a little bit of context: Embark runs two types of tests, JavaScript tests
and Solidity tests. It does that as part of a single process, keeping state in memory in-between those two test runs.
With that in mind, the commit mentioned above says the following:
1. Artifacts that Embark generates as part of its compilation process are erased after JS tests are done executing.
This makes a lot of sense as we don't want to leave any side effects undone when tests are finished.
2. The commit ensures that not only the artifacts are removed from disc, but also updates Embark's state in memory
for `contractFiles`. The reason for that is that otherwise, in the second test run for Solidity tests, Embark will
throw errors as it tries to look up the path for the artifacts in memory for all the Smart Contracts that had been
compiled before.
3. Last but not least, there's *another* state that needs a reset and that's the Smart Contract configuration. If Embark
doesn't reset the memory it'll assume in the second run that all of those Smart Contracts left in memory
"have no code associated to it", while in reality, they shouldn't be in memory in the first place.
So it seems that `config()` is called a second time with an empty Smart Contracts configuration just to ensure that memory
is reset and no error messages are shown.
As discussed earlier, this unfortunately also introduced a lot of side effects along the way as Embark tries to reregister
ENS subdomains from Smart Contracts that are marked as undeployed and therefore don't have an address to interpolate.
While there's probably different ways to go about it, the most straight forward fix is to simply not call `config()`
a second time when it's really not needed. If the goal is to just reset the memory, we can take advantage of
Embark's internal `config:contractsConfig:set` event, which is what this commit is doing.
The embark-utils package, since 4.1.0-beta.1, is a transitive DApp dependency;
but it's loaded in the main process (not a child process), so embark-utils' own
deps can't be indirectly supplied from embark itself via NODE_PATH.
When introducing the `embark-api-client` in https://github.com/embark-framework/embark/commit/c1bbdbf34
we didn't properly update Cockpits apiService, resulting in calls to API endpoints
that don't exist.
This commit fixes a bug where calls to Embark's API to subscribe to whisper
channels are in a broken state.
It also updates Cockpit's apiService to no longer pass ignored parameters to embark-api-client.
With the move of Embark's modules into their own packages, the names under
which they are registered in the API service have changed as well.
This caused Cockpit to no longer being able to properly detect whether
ENS is enabled in the current Embark project
This package comes with a `setUpEnv()` function that can be called to
prepare Embark's environment variables for different process contexts.
This allows us to set up Embark's environment within a test runner context
without the requirement of importing `packages/embark/src/lib/core/env.js`,
which happens to set up those necessary environment variables as a side effect.
It's important that a path to `packages/embark`'s root is passed down to `setUpEnv()`
to ensure `EMBARK_PATH` gets the correct value.
E.g. within a package `embark-console`, `setUpEnv()` can be called within its tests
like the following:
```
// packages/embark-console/src/test/console.js
import { joinPath, setUpEnv } from 'embark-utils';
setUpEnv(joinPath(__dirname, '../../../embark'));
```
Here, `__dirname + '../../../embark'` ensures `EMBARK_PATH` points to the root
of `packages/embark`. This might look different in other contexts.
For example calling this function from a test file within `packages/embark`, this would
look like this:
```
// packages/embark/src/test/some_file.js
import { joinPath, setUpEnv } from 'embark-utils';
setUpEnv(joinPath(__dirname, '../../'));
```
As part of 880a3a6946, we've introduced a
regression where the `colors` package isn't imported in the scope anymore where it's
needed. In this case the pipeline package. This resulted in log output messages
such as:
```
undefinedwriting fileundefined
```
Adding the `colors` package as dependency and importing it accordingly
fixes the issue.
Make the adjustment even if the test script is currently disabled. Consistently
use nyc to generate coverage with mocha even if the test script is currently
disabled.
If the `embark` cli is detected to be inside the monorepo, the template
generator yarn-links any template deps that are part of the monorepo into the
dapp. However, `embarkjs-connector-web3` now has a dependency on `embark-core`,
which in turn has a dependency on `embark-i18n`. That causes `npm install` to
fail inside the dapp because npm checks for deps of `embarkjs-connector-web3`
relative to the dapp instead of checking relative to the symlink. `yarn
install` does not suffer from that behavior so use it instead.
Move the debugger module to the `embark-debugger` package.
Handle case where `debug` is entered as a console command, and there is no transaction to be debugged.
add embark-i18n and mocha deps
Add support for `service api on/off` commands.
Deprecate commands `api start/stop` in favor of `service api on/off`.
`service api on` - Enables the API server serving Cockpit. Shows an error if the API server is already starting or started.
`service api off` - Disables the API server serving Cockpit. Shows an error if the API server is already stopping or stopped.
`api start` - This command has been deprecated in favor of `service api on` and will be removed in future versions.
`api stop` - This command has been deprecated in favor of `service api off` and will be removed in future versions.
`api:start` - This event has been deprecated and will be removed in future versions.
`api:stop` - This event has been deprecated and will be removed in future versions.
Remove support for `service whisper on/off` because Whisper cannot be started without first disabling it in the communications config, then restarting Embark.
Add documentation for the `service [process] on/off` command
This command was only added a few commits back so it is not considered a breaking change.
Refactor the `service [process] on/off` commands so that there is only one command. Previously we had a command registered for each process, ie:
```
service blockchain on/off
service ipfs on/off
…
```
Now, we only have one command with many options:
```
service [process] on/off - Starts/stops the process. Options: blockchain, embark, ipfs, api
```
Whisper is deliberately not included in the available options for the aforementioned reasons.
This enables removing unnecessary `core/fs` dependencies which can be
replaced with `fs-extra`.
This commit also fixes a bug introduced in f868d1216d
where methods from `embark.fs` weren't available.
The reason for that is because we have several *Process instances
that are created through child process communication, specifically
process.send() APIs. Using those APIs, we can only send data structures
however, methods attached on any of those will get lost.
This is the case when sending embark.fs through process.send().
We still need fs in those places though, mostly because they are relying
on embarkPath and dappPath().
These places are now importing those functions from `embark-core`. Other
API such as writeFile or mkdirp() can be accessed through fs-extra
or fs modules.
This pull-request upgrades `ethereumjs-wallet`, which has upgraded the underlying dependency on scrypt.js to 0.3.0, making scrypt an optional dependency and offering a pure JS version as a fallback.
The reasoning behind this is that scrypt is problematic to install in some systems, particularly those that don't have node-gyp setup and we have seen some weird issues when installing with elevated privileges (i.e. `sudo npm install -g scrypt`)
This avoids mistakenly placing process event handlers on the parent process
whenever the `embark-core` package is loaded. Also, don't listen for an
`'exit'` event on `process` and then call `process.exit(0)` since the event "is
emitted after the child process ends" ([docs][docs]), i.e. it's unnecessary to
do so and in any case it's not correct to always exit with code `0`.
