Display five contracts per page in the dashboard. Display ten contracts per
page in the contracts explorer and deployment page.
Sort contracts by name. In the future we can implement an option to sort by
block number and index within a block by calculating and including that
information as part of the server-side api response (based on a contract's
txhash).
Remove unnecessary contract filtering in the components since the containers
take care of it.
Make use of `listenToContracts` / `stopContracts` in DeploymentContainer.
During work on PRs #1492 and #1494 it became evident that it's not desirable to
show pagination controls unless the number of pages is greater than one.
Display a truncated account balance if the balance is greater than 20
characters in length. This keeps the "Balance", "Tx Count", and "Index" fields
well-aligned in lists of accounts.
In the account details page continue to show the full balance.
Display two accounts per page in the explorer overview. Display ten accounts
per page in the accounts explorer page.
Sort accounts by their api-supplied index numbers with the lowest index coming
first.
Change the `initBlockHeader` saga so that it triggers a re-fetch of accounts
and therefore the "Tx Count" numbers of displayed accounts will reflect
increased counts.
Make tabs draggable so they can be arranged how the user would like.
The dragging functionality locks the tabs to the parent container.
Support for multiple rows of tabs.
Styling updates for selected tabs.
When connected to metamask, and “Injected Web3” is selected on the Deployment page of Cockpit, check to see if contracts have already been deployed or not.
For contracts that have not been deployed, or set to an address in the config, these should now all be re-deployable.
Supports libraries (that have bytecode with `0x73<address><bytecode>`).
TL;DR
=====
Unregister (disable) the service worker in production builds of Cockpit. The
CRA dev server doesn't enable the service worker, so no changes are needed in
that context, i.e. `yarn start` in the monorepo.
**NOTE**: to effect these changes a user will need to load production Cockpit at
`localhost:55555` and then close all Cockpit tabs (or restart the
browser). This should be done for each browser that has been used to access
production Cockpit. See the *Step-by-Step* section below for more information.
Rationale
=========
There are a couple of factors:
* It's a bit confusing that after stopping `embark run` the production build of
Cockpit is still accessible at `localhost:55555`. That's owing to CRA's
[offline-first behavior][PWA] per the service worker it creates, which
Cockpit [currently registers][current] (enables).
* It can be really confusing, if you don't know or forget about the service
worker's behavior, that after a production rebuild of Cockpit the old build
is still used in the browser, even after a page refresh. As [explained][ofb]
in CRA's docs: *"users will end up seeing older content until they
close (reloading is not enough) their existing, open tabs."* A similar effect
is seen when switching between DApps, e.g. teller and embark_demo.
The CRA docs point to [some code][code] that could be adapted to an alert in
the UI prompting the user to close all tabs and reopen the app. That approach
definitely makes sense for DApps built with CRA that have opted-in to the
service worker. In fact, the service worker behavior would be critical in DApps
that make use of connected-/react-router because cold loads of routes that
don't actually correspond to static files couldn't otherwise work, i.e. if the
DApp is being served from ipfs/swarm.
But for Cockpit itself, when served from localhost with an express backend that
we control, little seems to be gained from offline-first behavior vs. a more
familiar behavior, i.e. when `embark run` isn't running then Cockpit isn't
accessible.
Step-by-Step
============
Flushing a site's service worker from cache can be tricky. The following steps
outline an approach to making sure the Cockpit in use is the one with service
worker disabled.
1. The first screenshot below shows the JavaScript console from a fresh load of
Cockpit with the service worker enabled, i.e. from a build on `master` at time
of writing and `embark run` running for the `embark_demo`. Note the messages
re: *"workbox"* and *"precaching"*.
![][step-1]
2. The next screenshot shows what happens when `embark run` is stopped and the
browser is refreshed. Service worker makes the page available offline, though
there are errors related to embark's API not being accessible.
![][step-2]
3. (a) Cockpit gets rebuilt on this PR's `refactor/cockpit-service-worker`
branch and `EMBARK_UI_STATIC=t embark run` is started; see [previous
commit][prevcom] re: `EMBARK_UI_STATIC`. (b) The browser is refreshed. Note the
message at the bottom re: *"New content is available"*.
![][step-3]
4. The Chrome browser is closed completely (command-Q), reopened and
`localhost:55555` is loaded again. Note there are *still* messages re:
*"workbox"* and *"precaching"*.
![][step-4]
5. The page is refreshed again and now the messages are completely gone.
![][step-5]
6. `embark run` is stopped and the page is reloaded, but there's a connection
error because no process is listening on `localhost:55555` — proof that
the service worker is no longer in play!
![][step-6]
Steps 3(b) to 6 will need to be repeated for each browser (Firefox, Safari,
etc.) that visited `localhost:55555` when the service worker was enabled. And
they'll need to be repeated again if the browser is later used with a build of
Cockpit predating this PR.

When a fallback function is encountered give its signature as `function()`,
disable row expansion, and omit the interaction form. Also label with a
`fallback` badge.
Create React App automatically determines the base path for links within
production build artifacts based on the project's `"homepage"` field in
`package.json`.
An [alternative][alt-setting] is to set the `PUBLIC_URL` environment variable
in `.env.production`. Take that approach so embark-ui's `"homepage"` can
continue to point to its home in the monorepo on GitHub.
Generate source maps in the production build of embark-ui. Doing so increases
the size of the package's tarball by a few MB (it was already large because of
the editor component), but the benefits of being able to much more easily debug
a production build (e.g. when interacting with users experiencing problems)
outweigh the size cost.

Don't implicitly rely on explorer overview having been loaded to initially
populate `entities.transactions`. Also, that container should watch for new
blocks/transactions same as the other explorer containers.
Restore `fetchTransactions` and related to TransactionsContainer. It's no
longer the basis of pagination (it didn't work as desired), but when navigating
through the transaction pages that action will ensure more transactions are
fetched so that the account page will list more of an account's transactions
over time. That was a side effect of `getTransactions` before it was removed in
favor of `getBlocksFull`, which is still the basis of revised pagination logic
in the transactions explorer.
Revise calculations related to transactions and pagination in the transactions
explorer and explorers overview.
Make the number of transactions to display per page configurable and set it to
3 in the explorers overview. Display a "No transactions..." message instead of
"0" when there are no transactions to display.
Introduce a `blocksFull` prop, action, api, etc. for calculating lists of
transactions relative to block objects that contain full transaction objects
instead of hash strings (the function backing the blocks endpoint already
supports that) and transaction receipts. In the future, the receipts can be
used to filter out constructor transactions for silent contracts.
Make pagination display conditional within the blocks explorer, same as in the
transactions explorer.
Filter silent contracts in the views that display contracts lists rather than
with `formatContractForDisplay` because the old approach prevents interaction
with a silent contract if a link to it is followed from the blocks or
transactions explorer, which is not desirable.
Rename contract "Transactions" tab to "Log". Display and allow filtering of all
contract methods. Disable debug button for pure/view functions and the
constructor.
Revise the filtering logic so that filters are combined together. Make the
status filter a drop down menu like the others.
Revise styling for consistent row height, alignment of text, and button sizes;
use a monospaced font in some cases to achieve the effect.
Handle enter/return correctly in forms within a contract's Interact tab.
Remove event rows from a contract's Interact tab.
Track pure/view calls in the blockchain proxy so they can be logged server-side
by console listener and reported in Cockpit within a contract's Log tab.
Eliminate double logging in the contracts manager. Ensure contracts deployed on
a fresh `embark run` have an `address` / `deployedAddress` property.
Revise calculations related to block numbers and pagination in the blocks
explorer and explorers overview.
Make the number of blocks to display per page configurable and set it to 5 in
the explorers overview.

Don't commit changes to private packages, with the exceptions of embark-typings
and embark-reset because those may switch from private to public, and also
because the latter will be included in `node_modules` of embark even if it is
private since embark-reset is presently a bundled dependency of embark.

`package.json` allows for a [`"files"` whitelist][files] to be specified as an
alternative to a top-level `.npmignore` within a package root. Maintaining
whitelists is generally easier and less error-prone than maintaining
blacklists, so implement a `"files"` list for all non-private packages in the
monorepo and remove unneeded `.npmignore` files.
Switch `embark-reset` from being a private package to one that will be
published, adjust the workspace's `"nohoist"` setting accordingly, and no
longer specify `embark-reset` as a bundled dependency of `packages/embark`. I
originally thought there might be a good reason not to publish it, but I no
longer think so.
Remove unnecessary LICENSE files in `packages/{embark,embark-ui}` since Lerna
will automatically copy the root LICENSE into any packages lacking that file,
i.e. before tarballs are packed and published to the NPM registry.
Change the `"author"` field of `packages/embarkjs-connector-web3` to match the
other packages, i.e. such that it matches the copyright assignment in the root
LICENSE. If that's not a desirable thing to do, then instead that package can
have a separate LICENSE file that has a copyright assignment for `"Jonathan
Rainville"`.
Supply some missing `.npmrc` files in `packages/*`.

Switching between the two tabs shown on the Dashboard for the cockpit was removing some of the logs that were previously displayed. This was due to an overlap in `id`’s being assigned to the logs from different processes.
To alleviate this, the reducers has been updated to not only check `id` but also `process.name`.
Additionally, the reducer was updated so that the number of logs for **each process** is set to `ELEMENTS_LIMIT`. For example, our `ELEMENT_LIMIT` is currently set to `200` and it would have meant that the total number of process logs across all processes would have been capped at 200. The current changes in this PR allow for 400 total logs, given that we have two processes being monitored for logs.
The services websocket was initiated in the AppContainer and causing all child components to continuously re-render every time there was a service check (which is effectively every second). In addition, the socket was never stopped when not needed (ie when the services component was unmounted).
Create a ServicesContainer that initiates the websocket as part of the container, and stops the socket when the container is unmounted.
Move the ContractsList to be part of the ContractsContainer with a `mode` switch.
Add Deployment page title and description.
A console warning is meant to appear in the browser console when the dapp is connecting to web3 using metamask and the blockchain client is geth. The warning displays information telling the user they should enable regular transactions to prevent known issues regarding transactions getting stuck.
The issue fixed here pertained to `warnAboutMetamask` vs `warnIfMetamask` - maybe there was a change that introduced this issue upstream.
Additionally, enabling and disabling of regular transactions via an API endpoint did not
Add ability to stop regular txs via query string, and validate request parameters.
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.
If a function receives a callback argument then it should not return a promise
if the caller's callback will be invoked. Both invoking a callback and
returning a promise can lead to at best confusion (in code review and at
runtime) and at worst non-deterministic behavior, such as race
conditions. Also, a caller supplying a callback may not handle a returned
promise, leading to unhandled rejection errors.
Refactor all readily identified functions where a callback argument can be
supplied but the function returns a promise regardless. Make use of
`callbackify` and `promisify` where it made sense to do so during the
refactoring. Some callsites of the revised functions may have been accidentally
overlooked and still need to be updated. Some functions that take callback
arguments may execute them synchronously, at odds with control flow of a
returned promise (if a callback wasn't supplied). Such cases should be
identified and fixed so that asynchronous behavior is fully consistent whether
the caller supplies a callback or receives a promise.
Make sure promises that pass control flow to a callback ignore rejections,
since those should be handled by the callback.
Don't return promise instances unnecessarily from async functions (since they
always return promises) and change some functions that return promises to async
functions (where it's simple to do so).
Whisper was using an ad hoc promise-like `messageEvents` object. However, that
object behaved more like an observable, since promises either resolve or
reject, and only do so one time. `messageEvents` was also intertwined with
callbacks. Replace `messageEvents` with RxJS Observable. `listenTo` now returns
Observable instances and callers can subscribe to them.
`Blockchain.connect` of embarkjs could suffer from a race condition where tasks
associated with `execWhenReady` might be ongoing when `connect`'s returned
promise resolves/rejects (or a caller supplied callback fires). Attempt to
ensure that returned-promise / supplied-callback control flow proceeds only
after `execWhenReady` tasks have finished. The control flow involved
is... rather involved, and it could use some further review and refactoring.
Bump webpack and the hard-source-plugin for webpack.

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.
