Summary: how did this ever work?
All build jobs must pass in the platform argument.
This also turns the "platform" argument into a required one.
I added a task to infer the platform argument from the filename here: t8306875

Summary: When we updated joi, the error message was changed. I removed the content to prevent similar errors in the future.

The profiler helper shouldn't live inside the packager itself, move
it to the packager.js file with other middlewares.

Summary:
1. When the server starts up, it only gives itself 30 second to live before receiving any connections/jobs
2. There is a startup cost with starting the server and handshaking
3. The server dies before the client has a chance to connect to it
Solution:
1. While the server should die pretty fast after it's done it's work, we should have a longer timeout for starting it
2. I also added accompanying server logs with client connection errors
Summary:
We don't currently support platform extensions in asset modules.
This adds supports for it:
```
require('./a.png');
```
Will require 'a.ios.png' if it exists and 'a.png' if it doesn't.
Summary:
Saw an issue with a build because of an ENONT error: https://fb.facebook.com/groups/716936458354972/permalink/923628747685741/
My hypothesis:
1. We issue a ping to the socket (in SocketInterface/index.js) a decides if the available socket is alive
2. We see that it's alive but by the time we actually connect to it the server would've died
Solution:
1. The server shouldn't die as long as there are clients connected to it (currently it only stay alive as long as there are jobs)
2. The "ping" should only disconnect once the client is connected
3. Finally, have a better error message than ENOENT
Summary:
Sourcemap urls were generated as just the pathname (no options) which meant that they generated source for the wrong bundle.
Even worse, there exists a race condition when multiple request to the same bundle has different types of paltform arguments (in this case one could be 'ios' and the other is undefined). The fix will this will come later as it's more involved -- will need to refactor the dependency resolver to have a per-request state.
Summary:
Fix failing test that matches the exact error string to match using `contains`.
I was under the impression that jest tests were running in CI -- turns out not yet.
Summary:
A few potential races to fix:
1. Multiple clients maybe racing to delete a zombie socket
2. Servers who should die because other servers are already listening are taking the socket with them (move `process.on('exit'` code to after the server is listening
3. Servers which are redundant should immediatly die
Summary:
Buck (our build system) currently starts multiple packager instances for each target and may build multiple targets in parallel. This means we're paying startup costs and are duplicating the work. This enables us to start one instance of the packager and connect to it via socket to do all the work that needs to be done.
The way this is structured:
1. SocketServer: A server that listens on a socket path that is generated based on the server options
2. SocketClient: Interfaces with the server and exposes the operations that we support as methods
3. SocketInterface: Integration point and responsible for forking off the server
Summary:
The transform step in currently the longest one in the bundling process. This adds a progress bar to track the transform progress.

Summary:
There are two fs steps and it wasn't clear why. This now puts the right label:
```
[9:38:25 PM] <START> Building in-memory fs for JavaScript
[9:38:27 PM] <END> Building in-memory fs for JavaScript (2030ms)
[9:38:27 PM] <START> Building in-memory fs for Assets
[9:38:27 PM] <END> Building in-memory fs for Assets (615ms)
```
Summary:
The `BundlesLayout` will be used as a persistent index. As such, it would be easier to avoid having dependencies to `Module`, `Package`, `Asset`, etc. We're not using that information for now and if we happen to need to use it we could always fetch it using the `ModuleCache`.
Summary:
We've decided to move the syntax for asynchronously requiring async dependencies. The new syntax works better with promises and therefore withe async/await as well. The new syntax looks like this: `System.import('moduleA').then(moduleA => {...});` or if you're using async/await you could simply do:
let moduleA = await System.import('moduleA');
new moduleA().someFunction();
If you need to require multiple dependencies just do:
Promise
.all([System.import('moduleA'), System.import('moduleB')])
.then((moduleA, moduleB) => {...})
or the equivalent using async/await
Summary:
Fix error in the template string (no plus, thinks it's a function).
And bump the timeout to 30 seconds because a file is taking more than 10 seconds `js/RKJSModules/Libraries/FBComponents/FBFed/FeedStoryFragments.js`
Summary:
Since JS doesn't have the guarantee that once a bundle is loaded it will stay in memory (and this is something we actually don't want to enforce to keep memmory usage low), we need to keep track of parent/child relationships on the packager to pass it down to native. As part of this diff, we also introduced an ID for each bundle. The ID for a child bundle is shynthetized as the bundleID of the parent module + an index which gets incremented every time a new bundle is created. For instance given this tree:
a,b
c f
d e g
the ID for `d` will be `bundle.0.1.2`, the one for e will be `bundle.0.1.3` and the one for `g` will be `bundle.0.5.6`. This information will be useful to figure out which bundles need to be loaded when a `require.ensure` is re-written.
Summary:
There's been a case where Babel can hang indefinitely on a file parse/transform. Possibly related to https://github.com/babel/babel/issues/2211
This adds a timeout to transform jobs and throws an error informing the user of the offending file. The timeout interval defaults to 10 seconds, but can be changed via an option.
Summary:
D2319999 introduced a regression where we stopped waiting for the "build haste map" step to finish before we accept any requests. This makes sure that we block on that.
Need to unbreak with this, but will follow up with a test to catch this in the future.
