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 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`.

Add support for ability to start and stop Swarm via command `service swarm on/off`.
Fix issue with swarm not starting due to missing web3 object.
`service swarm on` - starts a swarm node if not already started. Shows an error if the node is already starting or started.
`service swarm off` - kills the running swarm node as long as Embark has started the swarm process. If the swarm process was started externally, an error is shown.
In addition to introducing improvements per #1492 and #1494, adjust the
transactions request action to allow for a `blockLimit` argument, since that
API parameter is supported by embark.
Revise `changePage` to invoke `fetchTransactions` correctly, i.e. with
arguments pertaining to a starting block number and a block limit.
These changes together fix most of the pagination problems related to exploring
transactions, i.e. badly mis-ordered results are no longer displayed.
However, a *wart* still remains related to estimation of the total number of
transactions and pages. Sometimes the calculated number of pages for the
transactions explorer doesn't match up to the actual number of transactions on
the blockchain (owing to estimation). The pagination controls and display of
transactions will temporarily behave a little strangely if one jumps ahead in
the pages, e.g. a jump from cockpit explorer overview's transactions page 1 to
page 5 for embark's demo, if an additional transaction has been added and the
explorer overview is freshly loaded. This behavior is related to the fact that
actions such as `fetchBlocksFull` and `fetchTransactions` are async without any
means to determine when all actions have completed and React re-/rendering has
settled down.
There are probably some architectural changes that could improve the situation,
but they're outside the scope of this PR and in no way easy to solve by means
of React lifecycle methods. In fact, attempts to make an improvement with
`componentDidUpdate` (and watching what happens in the debugger) revealed the
nature of the problem, as described above.
Add support for ability to start and stop IPFS via command `service ipfs on/off`.
Add support for `ProcessState.Errored` process state in the `ProcessManager`. This allows for processes being launched and stopped to trigger an error and the resulting process will be in an errored state. Processes in errored states can still attempt to be started and stopped.
`service ipfs on` - starts an IPFS node if not already started. Shows an error if the node is already starting or started.
`service ipfs off` - kills the running IPFS node as long as Embark has started the IPFS process. If the IPFS process was started externally, an error is shown.

We could use similar comments for imports related to other `@types` packages,
but the need to do it for `@types/embark` (located in
`packages/embark-typings`) seems more pressing since `import ... from "embark"`
statements in the monorepo can be so easily misunderstood.
Note that the comments, and indeed the whole lines, are automatically erased
during babel transpilation of TypeScript since TS types aren't relevant after
the `.js` files are built.
If a package uses only `.js` then supply `--extensions ".js"`. If a package
uses only `.ts` then supply `--extensions ".ts"`. If a package uses both, then
supply `--extensions ".js,.ts"`.
The reason for this is that adding/removing TS/JS support ought to occasion
revising a package's `package.json` file and adjusting other scripts as well,
e.g. for linting. With these changes, it won't work to simply start adding
`.ts` files in a package's `src/` directory, which should prompt the developer
to review `package.json` and make the appropriate changes, and/or other
developers may realize changes need to be made during code review.
Implement scripts to collect coverage reports (JSON format) from all packages
in the monorepo that generate such reports. Reports are copied to
`<root>/.nyc_output/coverage-[pkg-dir-name].json`.
Implement scripts to generate a combined html report in `<root>/coverage`.
Adjust root `reset` and `clean` scripts to delete `<root>/.nyc_output` and
`<root>/coverage`.
Implement a script in `<root>/package.json` to generate a `text-lcov` report
and upload it to coveralls from CI builds. Remove coveralls from
`packages/embark`.
Supply `packages/embark` with an nyc configuration in its `package.json` and
have its `"test":` script generate both `json` and `html` reports.
Use nyc with `embarkjs`'s test suite: supply an nyc configuration in its
`package.json` and have its `"test":` script generate both `json` and `html`
reports.
Adjust `embarkjs`'s tests for more accurate coverage reporting.
Add support for `service webserver on/off` commands.
Deprecate commands `webserver start/stop` in favor of `service webserver on/off`.
Handles passing through of arguments to the function executed after process launch.
`service webserver on` - Enables the webserver serving the DApp. Shows an error if the webserver is already starting or started.
`service webserver off` - Disables the webserver serving the DApp. Shows an error if the webserver is already stopping or stopped.
`webserver start` - This command has been deprecated in favor of `service webserver on` and will be removed in future versions.
`webserver stop` - This command has been deprecated in favor of `service webserver off` and will be removed in future versions.
Several `embarkjs-*` packages specify a `"test":` script in their respective
`package.json` files but lack any tests, causing `yarn test` in the root of the
monorepo to fail. For now, disable those scripts.
Add support for `service blockchain on/off` in the console.
Add service on/off command for each process started by, ie `service blockchain on/off` and `service whisper on/off`.
`service blockchain off` - Kills the blockchain process, stops the web3 provider, and shuts down the proxy (if used). In the case of `embark blockchain`, the entire process is exited.
`service blockchain on` - Starts the blockchain process *as a child process of the main embark process* then starts the web3 provider. This happens regardless of whether or not it was initially started with `embark blockchain` (see known issues).
## Known issues
1. If the blockchain process was started with `embark blockchain`, and then the blockchain process is killed with the `service blockchain off` command, when the blockchain process is restarted with `service blockchain on`, it will be restarted as a child process of the main embark process. It may be possible to allow for the blockchain process to be restarted in the same process it was originally started in, however this will take more development effort and can be handled in a different PR.
2. Parity has not been tested as it is currently not working in the master branch.
3. This PR adds a generic registration of commands for each process, ie `service whisper on/off`, however the only supported command is the `service blockchain on/off` command. Further support for other commands can be handled in separate PRs.
