The problems described in embark PR #1166 can be resolved by implementing the
blockchain proxy with `http-proxy` directly instead of using `express` together
with `http-proxy-middleware`. The ultimate cause of the buggy behavior (the
"stuck sockets" problems described in #1166) is unknown.
The need to swallow some errors as described in embark PR #1181 is also
eliminated by dropping `http-proxy-middleware` and `express`.
For reasons unknown, `ECONNRESET` errors on websocket connections to embark's
blockchain proxy are not automatically handled on Windows as they are on macOS
and Linux (or those errors aren't happening on those platforms, it's difficult
to determine). Explicitly swallow such errors so the blockchain process doesn't
crash. Prior to this PR, the crash-behavior can be reproduced on Windows by
running `embark blockchain` and `embark run` in separate terminals and quitting
`embark run` while `embark blockchain` is still running.
Consistently use the `simples` package's `WsParser` to process websocket
traffic instead of using `WsParser` for requests and the `ws` package's
`Websocket.Receiver` for responses.
Consistently use `pump` to connect parser streams instead of using `pump` in
some places and `chain` in others. Drop use of `cloneable` (and the package
dependency) since it was used previously in hopes it would fix the errors, but
it's unnecessary and didn't fix them.
The webpack process took quite a while to run, and there were no updates in the console while running.
This PR adds a spinner (when there is no dashboard) and status updates every 5 seconds. When there is a dashboard, the updates are added to a new line.

Convert LongRunningProcessTimer to TypeScript
PR feedback and consistency changes
Changed the constructor signature to accept an options object instead of individual optional parameters, for readability.
Changed library_manager to use the spinner when not using the dashboard, for consistency’s sake. Additionally increased the update time for the library manager from 750ms to 1s.
Fix lint errors
Added `"variable-name": ["allow-leading-underscore”]` to `tslint.json` due to a lack of the ability to prefix backing variables with underscore. This is an [ongoing discussion](https://github.com/palantir/tslint/issues/1489), and something the community thinks should be implemented, as it the preferred way to use a property with backing variable in TypeScript.
Use proper stream parsing to consistently track JSON-RPC messages.
For HTTP POST requests use the `stream-json` package to assemble request and
response message objects.
For WebSocket requests continue to use `simples/lib/parsers/ws` to process
stream frames into messages. For Websocket responses use the Receiver class of
the `ws` package to process stream data into messages. In both cases, make use
of the `cloneable-readable` and `stream-chain` packages to avoid leaks.
This mishmash of stream parsing approaches is the result of much
experimentation to find a working solution. For example,
`simples/lib/parsers/ws` does't work for processing WebSocket responses and
`ws.Receiver` doesn't work for processing requests. Additional revisions may be
necessary.
Revise `blockchain_process/dev_funds.js` to use web3's HTTP provider if a DApp
disables the WebSocket proxy.
This commit automates our release process. It takes care of a couple of things:
- Bumps version number in package.json as needed, see below
- Generates changelog based on commit history
- Create release commit
- Tags release commit
- Pushes release commit including tags to upstream repository
- Publishes release on npm
There are a couple of options supported. The base command is run like this:
```
npm run release
```
This will do a minor bump and try to push to `origin` on `master`. However,
this can be altered with the following options.
```
npm run release -- --dry-run
```
Can be used to perform dry run and not actually committing, tagging, pushing,
publishing anything.
```
npm run release -- --release-as <something>
```
Something can be `minor`, `major`, `patch` or anything you want `foo`, `1.0.0` etc.
```
npm run release -- --prerelease alpha
```
Will create a prerelease version a la `4.0.0-alpha.x`.
```
npm run release -- --prerelease alpha --npm-dist-tag next
```
Publishes a dist tag on npm using dist tag `next`
```
npm run release -- --sign
```
Signs the release commit (you need to have PGP setup for that).
```
npm run release -- --repo-origin pascal --repo-branch foo/bar
```
Pushes the release commit into `pascal/foo/bar`.
yarn.lock files are generated for embark and embark-ui, and their package.json
files and other npm related files are updated to support and require using yarn
for development of embark itself and for embark's CI.
