1.11.0

This PR adds the ability to remap an already-loaded profile using a JavaScript source map. This is useful for e.g. recording minified profiles in production, and then remapping their symbols when the source map isn't made directly available to the browser in production.

This is a bit of a hidden feature. The way it works is to drop a profile into speedscope, then drop the sourcemap file on top of it.

To test this, I used a small project @cricklet made (https://gist.github.com/cricklet/0deaaa7dd63657adb6818f0a52362651), and also tested against speedscope itself.

To test against speedscope itself, I profiled loading a file in speedscope in Chrome, then dropped the resulting Chrome timeline profile into speedscope, and dropped speedscope's own sourcemap on top. Before dropping the source map, the symbols look like this:

After dropping the source map, they look like this:

I also added automated tests using a small JS bundle constructed with various different JS bundlers to make sure it was doing a sensible thing in each case.

# Background

Remapping symbols in profiles using source-maps proved to be more complex than I originally thought because of an idiosyncrasy of which line & column are referenced for stack frames in browsers. Rather than the line & column referencing the first character of the symbol, they instead reference the opening paren for the function definition.

Here's an example file where it's not immediately apparent which line & column is going to be referenced by each stack frame:

```
class Kludge {
  constructor() {
    alpha()
  }

  zap() {
    alpha()
  }
}

function alpha() {
  for (let i = 0; i < 1000; i++) {
    beta()
    delta()
  }
}

function beta() {
  for (let i = 0; i < 10; i++) {
    gamma()
  }
}

const delta = function () {
  for (let i = 0; i < 10; i++) {
    gamma()
  }
}

const gamma =
() => {
  let prod = 1
  for (let i = 1; i < 1000; i++) {
    prod *= i
  }
  return prod
}

const k = new Kludge()
k.zap()
```

The resulting profile looks like this:
![image](https://user-images.githubusercontent.com/150329/94976830-0db88200-04cb-11eb-86d7-934365a17c53.png)

The relevant line & column for each function are...

```
// Kludge: line 2, column 14
class Kludge {
  constructor() {
             ^
...
// zap: line 6, column 6
  zap() {
     ^
...
// alpha: line 11, column 15
function alpha() {
          ^
...
// delta: line 24, column 24
const delta = function () {
                       ^
...
// gamma: line 31, column 1
const gamma =
() => {
^
```

If we look up the source map entry that corresponds to the opening paren, we'll nearly always get nothing. Instead, we'll look at the entry *preceding* the one which contains the opening paren, and hope that has our symbol name. It seems this works at least some of the time.

Another complication is that some, but not all source maps include the original names of functions. For ones that don't, but do include the original source-code, we try to deduce it ourselves with varying amounts of success.

+# Contributing to speedscope
+
+Hi! This is a short guide & set of guidelines for contributing to speedscope.
+Contributors of all skill levels are welcome to submit pull requests.
+
+This project adheres to the Contributor Covenant [code of conduct](./CODE_OF_CONDUCT.md).
+All contributors are expected to uphold this code of conduct.
+
+## Setting up for development
+
+To start running speedscope locally, run the following:
+
+    git clone https://github.com/jlfwong/speedscope.git
+    cd speedscope
+    npm install
+    npm run serve
+
+This should open up a running version of speedscope in your default browser.
+
+In your terminal, you should see something like this:
+
+    $ npm run serve
+    > speedscope@0.7.1 serve /Users/jlfwong/code/speedscope
+    > parcel assets/index.html --open --no-autoinstall
+
+    Server running at http://localhost:1234
+    ✨  Built in 7.30s.
+
+Most of speedscope is written in TypeScript. If you're unfamiliar with
+TypeScript, then you can either just try to learn it as you go, then the
+[official TypeScript
+documentation](https://www.typescriptlang.org/docs/home.html) may be of use
+to you!
+
+If you're not sure where the code you want to modify lives, the [`README.md`
+in the `src/` directory](./src/README.md) might be helpful.
+
+## Code formatting
+
+All TypeScript code in speedscope is automatically formatted with
+[Prettier](https://prettier.io/). This means that while you're writing your code,
+you don't have to worry about following a formatting guide, because a program will
+format your code for you!
+
+The easiest way to use Prettier is via an editor integration. See the [Editor
+Integration](https://prettier.io/docs/en/editors.html) page from Prettier's
+documentation for help with that.
+
+If you don't want to do that, you can alternatively run the autoformatter by
+running `npm run prettier`.
+
+## Running tests
+
+All TypeScript tests are written use [Jest](https://jestjs.io/). To run the
+tests, run `npm run jest`.
+
+## Contributing new features
+
+Before contributing code to implement a new feature, please open an issue to
+discuss it first. Large pull requests that are submitted without first getting
+maintainer buy-in are unlikely to be reviewed or merged.
+
+For features that will cause a visual change, please include visual mockups of
+the change you're planning on making.
+
+## Contributing bug fixes
+
+If you discover a bug, please file an issue. If the code change required to
+fix it is small (< ~20 lines), then feel free to just open a PR to fix the
+issue without trying to get buy-in ahead of time.

+
+# Publishing
+
+Publishing speedscope is a multi-step process:
+
+1.  Test the release
+2.  Prepare the release
+3.  Publish to npm
+4.  Deploy the website
+5.  Upload a release to GitHub
+
+At time of writing, deployment assumes you're running macOS. It probably
+works if you're on a linux, and almost definitely does not work on Windows.
+
+## Test the release
+
+Speedscope is tested in CI, so all the automated tests should be passing. We'll
+just be doing a few sanity checks to make sure the build & deployment machinery is working correctly.
+
+Run `scripts/prepare-test-installation.sh`. This will do a mock publish &
+installation to ensure that the version we're about to publish is going to
+work. At the end of this command, it should echo a `cd` command to run in your shell
+to switch to the installation directory. Something like this:
+
+```
+Run the following command to switch into the test directory
+cd /var/folders/l0/qtd9z14973s2tw81vmzwkyp00000gp/T/speedscope-test-installation.9Ssdd2PZ/package
+```
+
+Run this command, to switch to the test directory.
+
+Inside of here, run `bin/cli.js`. This should open a copy of speedscope in browser.
+Try importing a profile from disk via the browse button and make sure it works.
+
+Next, try running `bin/cli.js dist/release/perf-vertx*`. This should immediately open
+speedscope in browser, and the perf-vertx file should load immediately.
+
+If everything looks good, proceed to "Prepare the release".
+
+## Prepare the release
+
+1.  Update the version manually in package.json (we intentionally don't use the `npm version` command)
+2.  Update CHANGELOG.md to indicate the changes that were made as part of this release
+3.  Commit the changes with the version name as the commit message, e.g. `git commit -m 0.6.0`
+4.  `git tag` the release. We use tags like `v0.6.0`, e.g. `git tag v0.6.0`
+5.  `git push && git push --tags`
+
+## Publish to npm
+
+Assuming everything went well in the previous two phases, publishing should just be
+a matter of running `npm publish`.
+
+### Verifying the publish
+
+To verify that the publish was successful, run `npm install -g speedscope`.
+Try `speedscope`, which should open speedscope in browser.
+Try `speedscope sample/profiles/stackcollapse/simple.txt`, which should immediately load the profile.
+
+## Deploying the website
+
+This step must follow the "Publish to npm" step, since it uses assets from
+the npm publish.
+
+https://www.speedscope.app/ is hosted on GitHub pages, and is published via pushing
+to the `gh-pages` branch. The `gh-pages` branch has totally different contents than
+other branches of this repository: https://github.com/jlfwong/speedscope/tree/gh-pages.
+
+It's populated by a deploy script which is invoked by running `npm run deploy` script. This populate a directory with assets pulled from npm, and
+boot a local server for you to test the compiled assets. Please do not skip
+the manual testing in this step.
+
+If everything looks good, you should be able to hit Ctrl+C, and you should see this prompt:
+
+```
+Commit release? [yes/no]:
+```
+
+If everything looks good, type `yes` then enter. This will commit to the `gh-pages` branch, and the site should automatically deploy shortly after.
+
+To check if a deploy has happened, you can check https://www.speedscope.app/release.txt
+which includes the version, the date, and the commit of the deploy.
+
+## Upload a release to GitHub
+
+This step must follow the "Publish to npm" step, since it uses assets from
+the npm publish.
+
+To make a zipfile suitable for uploading to GitHub as a release, run `scripts/prepare-zip-file.sh`.
+
+Once that's done, you should have a zip file in `dist/release/`
+
+Upload that file along with changelog notes to https://github.com/jlfwong/speedscope/releases/new

-### Firefox
-
-The `profile.json` file format output by Firefox can be saved and import into speedscope: https://developer.mozilla.org/en-US/docs/Tools/Performance
-
-### Node
-
-If you record profiling information like so:
-
-    node --prof /path/to/my/script.js
-
-Then this will generate one or more `isolate*.log` files. You can open
-the resulting profile in speedscope by running the following command:
-
-    node --prof-process --preprocess -j isolate*.log | speedscope -
-
-### Instruments.app
-
-You can import call trees from OSX Instruments.app into speedscope by
-selecting a row in the "Profile" view and select "Edit -> Deep Copy" from the
-menu then pasting directly into speedscope. This data contains only aggregate
-statistics, so the "Time Order" view and the "Left Heavy" view will look very
-similar.
-
-You can also import `.trace` files for time profiles by dragging them directly
-into the browser from Chrome.
-
-### `stackprof` Ruby profiler
-
-If the `raw: true` flag is set when recording a dump, the resulting json dump can be imported into speedscope.
-
-### `perf` and `DTrace`
-
-If you process the output of `perf` or `DTrace` first with Brendan Gregg's `stackcollapse-*.pl` scripts (https://github.com/brendangregg/FlameGraph#2-fold-stacks), the result can be imported into speedscope.

 ## Views
 
 ### 🕰Time Order
-
-In the "Time Order" view (the default), the stacks are ordered left-to-right in the same order as the occurred in the input file, which is usually going to be the chronological order they were recorded in. This view is most helpful for understand the behavior of an application over time, e.g. "first the data is fetched from the database, then the data is prepared for serialization, then the data is serialized to JSON". This is the only flame graph order supported by Chrome developer tools.
-
-In all flamegraph views, the horizontal axis represents the "weight" of each stack (most commonly CPU time), and the vertical axis shows you the stack active at the time of the sample.
-
-If you click on one of the frames, you'll be able to see summary statistics about it.

 In the "Left Heavy" view, identical stacks are grouped together, regardless of whether they were recorded sequentially. Then, the stacks are sorted so that the heaviest stack for each parent is on the left -- hence "left heavy". This view is useful for understanding where all the time is going in situations where there are hundreds or thousands of function calls interleaved between other call stacks.
 
 ### 🥪 Sandwich

 The Sandwich view is a table view in which you can find a list of all functions an their associated times. You can sort by self time or total time.
 It's called "Sandwich" view because if you select one of the rows in the table, you can see flamegraphs for all the callers and callees of the selected
 row.

+## Source Map Test Project
+
+This directory contains test files used to test whether the remapping of
+performance profiles using sourcemaps work correctly.
+
+Run `npm run build` to build the artifacts, then open the appropriate files in
+the `html` directory in whatever browser you're testing.
+
+The idea is to sourcemaps generated by a variety of tools, and also to take
+profiles from a variety of browsers, and hopefully see that they all get 
+remapped as expected.
+
+This project is set up to go through three levels of source-map indirection,
+and also using multiple different build chains.
+
+1. TypeScript -> JavaScript source generation
+2. JavaScript source -> JavaScript bundling
+3. Minification
+
+Some bundlers will swap the order of steps 2 & 3, or potentially merge them,
+but it's complex yet realistic enough that this will hoepfully suss out 
+problems.
