Prior to this commit Embark had a bug where, when running `$ embark run` inside
an Embark project that was freshly cloned or reset, it'd get stuck at loading
the Solidity compiler.
However, this only seemed to happen when Embark was used with its dashboard. When
running
```
$ embark run --nodashboard
```
instead, Embark loaded Solidity successfully and moved on with compilation.
This bug pretty much boiled down to `SolidityProcess` not receiving a valid `Logger`
dependency when instantiated via `SolcW`. The reason this was happening
is that we were sending the needed dependencies via `ProcessLauncher.send()`, which
serializes/deserializes its sent data.
```
solidityProcessLauncher.send({action: 'init', options: { logger: this.logger }});
```
And inside `SolidityProcess`
```
process.on('message', (msg) => {
if (msg.action === "init") {
solcProcess = new SolcProcess(msg.options);
}
...
}
```
`SolcProcess` passes its `logger` instance down to `longRunningProcessTimer` which
uses methods on `Logger`.
However, since the data had been serialized, all prototype methods on the data is
gone, resulting in an error, which made Embark stop.
**Why was this only a problem when using the dashboard?**
Turns out we've only relied on `Logger.info()` in case the dashboard is used.
[PR 1318][PR1318] introduces a monorepo member that's used as a DApp
dependency, but the present arrangement whereby `test_dapps/` is an embedded
monorepo makes it difficult to develop and test such packages in tandem with
changes to `test_dapps/packages/*`.
Reorganize `test_dapps/*` as members of the root monorepo and make various
adjustments accordingly. This makes it easy to develop test dapps and any
packages they depend on simultaneously, but we lose the CI/QA arrangement where
test dapps are run with an embark installed from fresh tarballs. That
arrangement, which is quite worthwhile as a means to detect problems arising
from transitive dependencies as soon as possible, will be re-introduced in
another PR, possibly involving an auxiliary repository such as
embark-framework/dapp-bin.
Since the `package.json` `"test"` scripts of `test_dapps/*` are now kicked off
as part of `yarn test` in the root, and since port allocation isn't fully
dynamic, it's important to run `yarn test` with `lerna run`'s `--concurrency=1`
option. For the same reasons, the root `ci` and `qa` scripts are similarly
restricted. In the future, this setup can be refactored and improved, along
with use of `lerna run`'s `--since` option to increase testing efficiency in
CI.

Prior to this commits `this.contractsFiles` kept growing at run time
for every file change that was detected by Embark.
The reason for that was a bug in a condition that determines whether
a subset of contract files needed to be added to memory or not.
In addition to that we kept pushing externally loaded contract files into
memory, even if they already existed in memory.
Don't import git history of embark-framework/EmbarkJS, simply copy over the
sources. Modify `package.json`, etc. re: being situated in the monorepo.
Make use of the root babel config but extend with
`packages/embarkjs/.babelrc.js`.
Build `test/` scripts into `build-test/` and git-ignore `build-test/`.
Revise `Blockchain.connect()` so that if the caller supplies a callback then a
promise is not returned.
Revise tests to test `Blockchain.connect()` usage with and without a callback.
Relative `"include"` path/s in a `tsconfig.json` are relative to the directory
in which the config is located, so each monorepo package that uses typescript
needs its own `tsconfig.json` that `"extends"` the root config.
For now, disable the `"typecheck"` script in embark-graph and embark-vyper, but
leave the relevant pieces in place (devDeps, configs) so that when they're
converted to TypeScript the scripts can simply be re-enabled. The problem is
that if no `.ts` files are present in the path/s specified in `"include"` of
`tsconfig.json`, tsc will exit with error.
PR 1304 introduced a regenerated `yarn.lock` at the root. Somehow, that's
responsible for the error described in [a comment on PR 1307][error].
Restore the `yarn.lock` from 3f61e314d9, then
catch it up with `yarn reboot:full` in the root. `yarn typecheck` then runs
without error in `packages/embark`.

Move `packages/embark`'s eslint config into the monorepo root.
Remove `"plugin:react/recommended"` since it's not commonly needed.
Put a `"eslintConfig"` config key/object in `packages/embark`'s `package.json`
that directs eslint to extend the root config; other `packages/*` can do
likewise.
Setup a `babel.config.js` in the root of the monorepo to be used by
`packages/*`. It won't be used by some packages, e.g. `packages/embark-ui`, but
most of them should use it instead of rolling their own.
Allow for package-level modifications by specifying `babelrcRoots` in the root
`babel.config.js`
Use the babel `--root-mode upward` option in `packages/embark`'s `build`
script. Other packages intending to use the common config should do likewise.
Use a `.babelrc.js` in `packages/embark` to supply the package-specific
`ignore` settings.
Make packages used by the common config devDeps of the root.
Extract babel-related devDeps from `packages/embark`, but don't extract the
non-dev deps since those are used by embark's pipeline in a production
install. Normally, it should only be necessary to have `@babel/cli` and
`@babel/core` in devDeps, and possibly `@babel/runtime-corejs2` in deps, plus
any package-specific babel-related dev/deps. Once we deprecate the pipeline, we
can finish the extraction.
Use `ncu -f '/babel/' -u` to bump the versions of all babel-related deps in the
root and in `packages/embark`. We get better space/time savings from the yarn
workspace when versions match.

WIP: don't pack a tarball since it's a private package
WIP: no need to list as a devDep
Put common patterns we expect to use across most `packages/*` into the
top-level `.gitignore`. If there are package-specific patterns they can go in
that package's `.gitignore`. For example, `packages/embark-ui` ignores its
`build/` directory while commonly we ignore the packages' `dist/` directories.
Yarn merges `.yarnrc` from the current working directory with `.yarnrc` files
higher in the directory tree, so that file isn't needed in each package.
Unfortunately, npm doesn't do the same for `.npmrc` files, so a similar cleanup
isn't possible.
Add version info to `test_app/extensions/embark-service/package.json` to that
`yarn install` can work correctly if manually invoked in `test_app`.
TL;DR
=====
`yarn install` in a fresh clone of the repo.
`yarn reboot` when switching branches.
When pulling in these changes, there may be untracked files at the root in
all/some of:
```
.embark/
.nyc_output/
coverage/
dist/
embark-ui/
test_apps/
```
They can be safely deleted since those paths are no longer in use at the root.
Many of the scripts in the top-level `package.json` support Lerna's [filter
options]. For example:
`yarn build --scope embark` build only `packages/embark`.
`yarn build --ignore embark-ui` build everything except `packages/embark-ui`.
Scoping scripts will be more useful when there are more packages in the
monorepo and, for example, `yarn start` doesn't need to be invoked for all of
them while working on just a few of them simultaneously, e.g `embark` and
`embarkjs`.
It's also possible to `cd` into a particular package and run its scripts
directly:
```
cd packages/embark && yarn watch
```
Hot Topics & Questions
======================
What should be done about the [README][embark-readme] for `packages/embark`?
Should the top-level README be duplicated in that package?
Lerna is setup to use [Fixed/Locked mode][fixed-locked], and accordingly
`packages/embark-ui` is set to `4.0.0-beta.0`. The same will be true when
adding embarkjs, swarm-api, etc. to the monorepo. Is this acceptable or do we
want to use [Independent mode][independent]?
Scripts
=======
If a package doesn't have a matching script, `lerna run` skips it
automatically. For example, `packages/embark-ui` doesn't have a `typecheck`
script.
`yarn build`
------------
Runs babel, webpack, etc. according to a package's `build` script.
`yarn build:no-ui` is a shortcut for `yarn build --ignore embark-ui`.
`yarn ci`
---------
Runs a series of scripts relevant in a CI context according to a package's `ci`
script. For `packages/embark` that's `lint typecheck build test package`.
Also runs the `ci` script of the embedded `test_dapps` monorepo.
`yarn clean`
------------
Runs rimraf, etc. according to a package's `clean` script.
`yarn globalize`
----------------
Makes the development embark available on the global PATH, either via
symlink (Linux, macOS) or a shim script (Windows).
`yarn lint`
-----------
Runs eslint, etc. according to a package's `lint` script.
`yarn package`
--------------
Invokes `npm pack` according to a package's `package` script.
`yarn qa`
---------
Very similar to `ci`, runs a series of scripts according to a package's `qa`
script. The big difference between `ci` and `qa` is that at the top-level `qa`
first kicks off `reboot:full`.
There is a `preqa` script ([invoked automatically][npm-scripts]), which is a
bit of a wart. It makes sure that `embark reset` can be run successfully in
`packages/embark/templates/*` when the `reboot` script invokes the `reset`
script.
The `qa` script is invoked by `yarn release` before the latter proceeds to
invoke `lerna publish`.
`yarn reboot`
-------------
Invokes the `reset` script and then does `yarn install`.
The `reboot:full` variant invokes `reset:full` and then does `yarn install`.
`yarn release`
--------------
Works in concert with [lerna publish], which will prompt to verify the version
before proceeding. Use `n` to cancel instead of `ctrl-c` as `lerna publish` has
been seen to occasionally misbehave when not exited cleanly (e.g. creating a
tag when it shouldn't have).
```
yarn release [bump] [--options]
```
* `[bump]` see [`publish` positionals][pub-pos] and [`version`
positionals][ver-pos]; an exact version can also be specified.
* `--preid` prerelease identifier, e.g. `beta`; when doing a prerelease bump
will default to whatever identifier is currently in use.
* `--dist-tag` registry distribution tag, defaults to `latest`.
* `--message` commit message format, defaults to `chore(release): %v`.
* `--sign` indicates that the git commit and tag should be signed; not signed
by default.
* `--release-branch` default is `master`; must match the current branch.
* `--git-remote` default is `origin`.
* `--registry` default is `https://registry.npmjs.org/` per the top-level
[`lerna.json`][lerna-json].
To release `4.0.0-beta.1` as `embark@next` (assuming version is currently at
`4.0.0-beta.0`) could do:
```
yarn release prerelease --dist-tag next
```
For *test releases* (there is no longer a `--dry-run` option) [verdaccio] and a
filesystem git remote can be used.
Condensend instructions:
```
mkdir -p ~/temp/clones && cd ~/temp/clones
git clone git@github.com:embark-framework/embark.git
cd ~/repos/embark
git remote add FAKEembark ~/temp/clones/embark
```
in another terminal:
```
npm i -g verdaccio && verdaccio
```
in the first terminal:
```
yarn release --git-remote FAKEembark --registry http://localhost:4873/
```
`yarn reset`
------------
Invokes cleaning and resetting steps according to a package's `reset`
script. The big difference between `clean` and `reset` is that `reset` is
intended to delete a package's `node_modules`.
The `reset:full` variant deletes the monorepo's top-level `node_modules` at the
end. That shouldn't be necessary too often, e.g. in day-to-day work when
switching branches, which is why there is `reboot` / `reset` vs. `reboot:full`
/ `reset:full`.
Errors may be seen related to invocation of `embark reset` if embark is not
built, but `reset` will still complete successfully.
`yarn start`
------------
Runs babel, webpack, tsc, etc. (in parallel, in watch mode) according to a
package's `start` script.
`yarn test`
-----------
Run mocha, etc. according to a package's `test` script.
The `test:full` variant runs a series of scripts: `lint typecheck test
test_dapps`.
`yarn test_dapps`
-----------------
Runs the `test` script of the embedded `test_dapps` monorepo.
The `test_dapps:ci` and `test_dapps:qa` variants run the `ci` and `qa` scripts
of the embedded `test_dapps` monorepo, respectively.
`yarn typecheck`
----------------
Runs tsc, etc. according to a package's `typecheck` script.
Notes
=====
`npx` is used in some of the top-level and package scripts to ensure the
scripts can run even if `node_modules` is missing.
[`"nohoist"`][nohoist] specifies a couple of embark packages because
[`restrictPath`][restrictpath] is interfering with access to modules that are
located in a higher-up `node_modules`.
All dependencies in `packages/embark-ui` have been made `devDependencies` since
its production build is self-contained.
`packages/embark`'s existing CHANGELOG's formatting has been slightly adjusted
to match the formatting that Lerna will use going forward (entries in the log
haven't been modified).
Lerna will generate a CHANGELOG at the top-level and in each package. Since
we're transitioning to a monorepo, things may look a little wonky with respect
to old entries in `packages/embark/CHANGELOG.md` and going forward we need to
consider how scoping our commits corresponds to member-packages of the
monorepo.
In `packages/embark`, `test` invokes `scripts/test`, which starts a child
process wherein `process.env.DAPP_PATH` is a temporary path that has all of
`packages/embark/dist/test` copied into it, so that paths to test
helpers/fixtures don't need to be prefixed with `dist/test/` and so that a
`.embark` directory doesn't get written into `packages/embark`.
The `"engines"` specified in top-level and packages' `package.json` reflect a
node and npm pair that match (a source of confusion in the past). The pair was
chosen according to the first post v5 npm that's bundled with node. A
`"runtime"` key/object has been introduced in `packages/embark/package.json`
which is used as the basis for specifying the minimum version of node that can
be used to run embark, and that's what is checked by `bin/embark`.
Some changes have been introduced, e.g. in `lib/core/config` and
`lib/utils/solidity/remapImports` so that it's *not* implicitly assumed that
`process.env.DAPP_PATH` / `fs.dappPath()` are the same as
`process.cwd()`. There are probably several++ places where that assumption is
still in effect, and we should work to identify and correct them.
`embark reset` now deletes `embarkArtifacts/` within a dapp root, and
`embarkArtifacts/` is git-ignored.
`lib/core/env` adds all `node_modules` relative to `process.env.EMBARK_PATH` to
`NODE_PATH` so that embark's modules can be resolved as expected whether
embark's `node_modules` have been deduped or are installed in npm's flat
"global style".
`checkDependencies` has been inlined (see `lib/utils/checkDependencies`) and
slightly modified to support dependencies that have been hoisted into a
higher-up `node_modules`, e.g. as part of a yarn workspace. eslint has been
disabled for that script to avoid more involved changes to it.
`test_apps` is not in `packages/embark`; rather, there is `test_dapps` at the
top-level of the monorepo. `test_dapps` is an embedded monorepo, and its `ci` /
`qa` scripts `npm install` embark from freshly built tarballs of the packages
in the outer monorepo and then use that installation to run `embark test` in
the dapps. This should allow us to rapidly detect breakage related to
auto-bumps in transitive dependencies.

This commit fixes a bug where it throws while trying to compile solidity
files as it dereferences its `this`.
Unfortunately passing methods as lambda callbacks doesn't correctly
resolve its `this` scope even within fat arrow functions, resulting in
unexpected behaviour where `this` inside lambda is `undefined`.
Remapping of imports was failing if the file had already had it’s import replaced with a pattern that would match with subsequent replacement attempts. For example, if the dapp contract contained
```
import ".embark/node_modules/zeppelin-solidity/contracts/ownership/Ownable.sol”;
```
which lives in `node_modules`, then `zeppelin-solidity/contracts/ownership/Ownable.sol` would be replaced with `.embark/node_modules/zeppelin-solidity/contracts/ownership/Ownable.sol`, resulting in:
```
import ".embark/node_modules/zeppelin-solidity/contracts/ownership/Ownable.sol";
```
On subsequent replacements of the same file, the same replacement would occur, resulting in the incorrect
```
import ".embark/node_modules/.embark/node_modules/zeppelin-solidity/contracts/ownership/Ownable.sol";
```
