This issue was caused by a string to integer conversion. In JavaScript,
when converting a string that starts with `0` (which is the case for tx
hashes) to an integer using `parseInt` it will always yield 0. That,
combined with a block with number 0 would always return a block result
instead of the transaction.
```
> parseInt("0xluri", 10)
0
```
This PR checks if the resulting number equals the string that was
provided on top of checking for the block number.
Previously, templates were in a subdirectory of `packages/embark`. Reorganize
them so that they are member packages of the monorepo. This allows them to
cleanly depend on other members of the monorepo,
e.g. `embarkjs-connector-web3`.
It is desirable for the templates, in the context of the monorepo, to specify
embark as a dependency, to take advantage of `npx embark test` (and it's a
"forward looking" setup re: how we plan to evolve embark). However, if embark
were to specify the template packages as dependencies a circular relationship
would be introduced, which is [unsupported by Lerna][circular]. Therefore,
revise the template generator so that all templates are resolved / fetched at
runtime, i.e. `boilerplate`, `demo`, and `simple` are no longer
"built-ins" *per se*. This change won't be apparent to embark's users, but it
does mean that the template generator won't work (in a production install of
embark) if it can't connect to the npm registry, i.e. when the user runs
`embark demo` or `embark new [--simple]`. When embark is inside the monorepo,
templates are resolved and copied from the yarn workspace rather than being
fetched from the registry, which is convenient for development. Also, any
template dependencies that are members of the monorepo are linked into the
copied template's `node_modules` rather than being installed from the registry,
again for convenience. During template generation, remove scripts and
dependencies that pertain only to membership in the monorepo; for now, that
involves removing embark as a dependency since we're not quite ready for that
arrangement to be the default, i.e. outside of the monorepo.
Refactor the root scripts so that more of them can consistently be used with
Lerna's filter options, e.g. `--scope` and `--ignore`. "Combo" scripts that
don't support filtering generally have a `:full` postfix.
Flip `clean` and `reset` scripts at the root and in the member packages for
consistency re: Lerna's notion of `clean` and embark's notion of `reset`. Have
each package run its `reset` script when its `clean` script is invoked (and
that's all for now), relying on `lerna clean` to delete packages'
`node_modules` in view of how Lerna's topological sorting works.
Lift the implementation of `embark reset` into a private package in
`packages/embark-reset` and make it a bundled dependency of embark. Packages in
`dapps/*` depend on `embark-reset` directly and make use of it with `npx
embark-reset` (but only in monorepo context). This removes a "wart" where
reboots could show errors when embark's sources aren't already built in
`packages/embark/dist`. Users will not notice any difference since `embark
reset` works as before, transparently making use of the `embark-reset`
package. The only downside to having it be a bundled dependency of embark is
that bundled deps have all of their `node_modules` included in the tarball
built with `npm pack` (that's why having the templates as bundled dependencies
of embark isn't a viable approach). However, `embark-reset` only has one
dependency, `rimraf`, which is a tiny module, so the cost seems acceptable.
As part of the reorganization, move `test_dapps` into `dapps/tests` and
`packages/embark/templates` into `dapps/templates`. Keep the directory names
short but revise the package names to facilitate simple filtering with
`embark-dapp-*`. Consolidate `.yarnrc` and `.gitignore` and clean up some
redundant ignore listings.
Scripts run with `--scope embark-dapp-*` use `--concurrency=1` to avoid
conflicts that could arise over network ports. The `ci:full` and `qa:full`
scripts use `--concurrency=1` in all scopes, for two reasons: resource
limitations on Travis and AppVeyor result in slower runs with concurrency >1,
and if something fails in those contexts it's easier to see what went wrong
when Lerna's output isn't interleaved from a bunch of scripts in `packages/*`.
Bump the Lerna version.

Reproduce:
1. Go to cockpit > transactions
2. Click a transaction
3. There will be a flicker of an error, then the decoded tx displays OK. Inspecting the network requests, there is a 500 error with a response of
```
AssertionError [ERR_ASSERTION]: invalid remainder
```
This error is also printed in the console.
The issue is that the transaction is not a raw transaction, so instead of trying to decode the non-raw transaction, the transaction can be decoded by web3.
**Cache suggestions**
Suggestions are cached for better performance on each request. When contracts are deployed, the suggestion cache is cleared, allowing for updated contract methods to be built in to the suggestions.
** Handle edge cases **
Handle cases when console command is parsed as an empty string, or possibly returns an empty object, which would cause `Object.getOwnPropertyNames` to throw an error (that is ultimately swallowed).
Swarm was not being registered as a service due to a recent change that introduced a bug. The previous change was meant to register “swarm” as a console command to provide output for the `swarm` console command when swarm had not been registered in the VM. The bug, however, returned too early in the cases when swarm was meant to be enabled, thus effectively not registering the entire process.
The fix simply returns only when swarm is in fact, disabled, and also alters slightly the way swarm is determined to be enabled (the changes of which have been copied over to `ipfs`).
Add the ability to pass an error in the callback of an event action.
Currently, event actions could either pass back a an error OR a result, but not both, and with no way to distinguish between the two parameters. This PR adds the ability to pass an error as the first parameter of the action callback.
An example of a use case that this fixed: errors on `deployIf` were silently swallowed, which has now been fixed.
All instances of `events.request(“deploy:contracts”)` were given an `error` parameter in their callback, and errors printed if it is not undefined.
All instances of `registerActionForEvent` were combed to ensure any callbacks were passing the expected error and result.
`web3.eth.getAccounts` was returning an empty array in the console due to a change, that I’m unsure of what the original intention was for.
@andremederios, could you please take a look, and let me know if this breaks the intention of the original changes?
Cockpit whisper messages were not being subscribed to due to a inocuous bug that would swallow errors and ultimately not be subscribed to the `rxjs` observer.
This PR fixes a number of issues relating to the cockpit console.
#### Console commands display in cockpit console
Fix cockpit console not displaying console usage commands that included “<usage option>”. For example “resolve <name>” would not display the “<name>” part, as it was attempting to write this in as HTML (ansi-to-html conversion).
This was fixed by replacing any instances of “<usage>” with “[usage]”. Please note that future usage strings should not contain text wrapped in “<>”.
#### Autosuggestions for “web.eth.” not appearing
Fix “web3.eth.” not suggesting members of `web3.eth`. This was due to a `Object.keys(web3.eth)` throwing `'getOwnPropertyDescriptor' on proxy: trap returned descriptor for property 'defaultAccount' that is incompatible with the existing property in the proxy target` in the console. Changing `Object.keys` to `Object.getOwnPropertyDescriptor` solved the problem.
#### Fix autosuggestion of known console commands (ie from plugins)
Fix known console commands (ie from plugins) not being autosuggested. For example, typing “web”, should autosuggest `webserver start/stop`, `log webserver on`, and `log webserver off`.
This PR adds in support for registered console commands (from plugins).
In addition to `EmbarkJS.Storage` not being available in the console (ie `await EmbarkJS.Storage.isAvailable() alway returned false), the error `Could not connect to a storage provider using any of the dappConnections in the storage config` would always appear in the console. The storage operations in the dapps were working OK.
The fix to this was three-fold:
1) Wait for the ipfs process to be started before attempting to run the `EmbarkJS.Storage.registerProvider/setProvider` in the console.
2) Wait for `EmbarkJS.Storage.registerProvider` to be called before `EmbarkJS.Storage.setProvider`. This was actually handled in the previous PR.
3) Remove any async operations from the `setProviders` method in the storage module. This was causing `callback is not defined` errors which were being swallowed and masqueraded as an unsuccessful attempt to connect to a `dappConnection` or `upload` config.
For every provider registered and set with EmbarkJS, auto generate events to inform other modules of the state of the provider.
Any provider that belongs to EmbarkJS (currently Blockchain, Names, Messages, and Storage) will have both a `runcode:<provider name>:providerRegistered` and a `runcode:<provider name>:providerSet` event created automatically when the `CodeRunner` is instantiated.
Once the `registerProvider` code is run through the VM, ie `EmbarkJS.Blockchain.registerProvider(…)`, the corresponding event will be fired, ie `runcode:blockchain:providerRegistered`.
Likewise, once the `setProvider` code is run through the VM, ie `EmbarkJS.Blockchain.setProvider(…)`, the corresponding event will be fired, ie `runcode:blockchain:providerSet`.
Additional updates/fixes with this PR:
* Move `CodeRunner` to TypeScript
* Fix console errors with ENS and Storage due to a recent PR that waits for `code-generator:ready`. The solution here was to ensure that `code-generator:ready` is requested, so that premature events can be handled.
Fix demo not running, by fixing the following issues:
This was due to the removal of `Web3` from the VM initialisation in a recent PR. The reasoning behind the removal was so that the modules that need Web3 could require it as needed, however, it is needed in 3 modules (ENS, Whisper, and web3Connector), all of which would define `const Web = …` in the code generated EmbarkJS, thus causing issues in itself. This needs to be rethought prior to removing it from the VM sandbox.
Because Web3 is back to being required in the global sandbox of the VM, it does not need to be registered in the `web3Connector` module, hence the removal of the `runcode:register`.
Module not found: Error: Can't resolve 'embarkArtifacts/contracts/SimpleStorage.js' in '/Users/emizzle/temp/embark_demo/app/components’`
This was fixed by replacing
```
import SimpleStorage from 'Embark/contracts/SimpleStorage';
```
with
```
import SimpleStorage from '../../embarkArtifacts/contracts/SimpleStorage';
```
