[0.54.4] Bump version numbers

Fix blob response parsing for empty body on iOS
Summary: We currently handle empty body poorly in the iOS blob implementation, this happens because of an early return that cause the blob response to not be processed by the blob module, resulting in an empty string as the body instead of a blob object. We also need to make sure to create an empty blob object when data is nil (empty body) as per the XMLHttpRequest spec. The Android implementation was already handling this properly. Fixes #18223 Send a HEAD request ```js fetch('https://apipre.monkimun.com/whoami', { body: null, method: 'HEAD', headers: { Accept: 'application/json', 'Content-Type': 'application/json', }, }) ``` [IOS][BUGFIX][Blob] - Fix blob response parsing for empty body Closes https://github.com/facebook/react-native/pull/18547 Differential Revision: D7415950 Pulled By: hramos fbshipit-source-id: 56860532c6171255869f02a0960f55d155184a46

+(Write what happened. Add screenshots!)

+### Reproducible Demo
+
+<!--
+  Please share a project that reproduces the issue.
+  There are two ways to do it:
+
+    * Create a new app using https://snack.expo.io/ and try to reproduce the issue in it.
+      This is useful if you roughly know where the problem is, or can’t share the real code.
+
+    * Or, copy your app and remove things until you’re left with the minimal reproducible demo.
+      This is useful for finding the root cause. You may then optionally create a Snack.
+
+  This is a good guide to creating bug demos: https://stackoverflow.com/help/mcve
+  Once you’re done, copy and paste the link to the Snack or a public GitHub repository below:

+
+(Paste the link to an example project and exact instructions to reproduce the issue.)
+
+<!--
+  What happens if you skip this step?
+
+  Someone will read your bug report, and maybe will be able to help you,
+  but it’s unlikely that it will get much attention from the team. Eventually,
+  the issue will likely get closed in favor of issues that have reproducible demos.
+
+  Please remember that:
+
+    * Issues without reproducible demos have a very low priority.
+    * The person fixing the bug would have to do that anyway. Please be respectful of their time.
+    * You might figure out the issues yourself as you work on extracting it.

-# Code of Conduct
+# [Open Source Code of Conduct](https://code.facebook.com/codeofconduct)

-Facebook has adopted a Code of Conduct that we expect project participants to adhere to.
-Please read the [full text](https://code.fb.com/codeofconduct/)
-so that you can understand what actions will and will not be tolerated.
+This code of conduct outlines our expectations for participants within the **Facebook Open Source** community, as well as steps to reporting unacceptable behavior. We are committed to providing a welcoming and inspiring community for all and expect our code of conduct to be honored. Anyone who violates this code of conduct may be banned from the community.
+
+Our open source community strives to:
+
+* **Be friendly and patient.**
+* **Be welcoming:** We strive to be a community that welcomes and supports people of all backgrounds and identities. This includes, but is not limited to members of any race, ethnicity, culture, national origin, colour, immigration status, social and economic class, educational level, sex, sexual orientation, gender identity and expression, age, size, family status, political belief, religion, and mental and physical ability.
+* **Be considerate:** Your work will be used by other people, and you in turn will depend on the work of others. Any decision you take will affect users and colleagues, and you should take those consequences into account when making decisions. Remember that we’re a world-wide community, so you might not be communicating in someone else’s primary language.
+* **Be respectful:** Not all of us will agree all the time, but disagreement is no excuse for poor behavior and poor manners. We might all experience some frustration now and then, but we cannot allow that frustration to turn into a personal attack. It’s important to remember that a community where people feel uncomfortable or threatened is not a productive one.
+* **Be careful in the words that you choose:** we are a community of professionals, and we conduct ourselves professionally. Be kind to others. Do not insult or put down other participants. Harassment and other exclusionary behavior aren’t acceptable. This includes, but is not limited to:
+  * Violent threats or language directed against another person.
+  * Discriminatory jokes and language.
+  * Posting sexually explicit or violent material.
+  * Posting (or threatening to post) other people’s personally identifying information (“doxing”).
+  * Personal insults, especially those using racist or sexist terms.
+  * Unwelcome sexual attention.
+  * Advocating for, or encouraging, any of the above behavior.
+  * Repeated harassment of others. In general, if someone asks you to stop, then stop.
+* **When we disagree, try to understand why:** Disagreements, both social and technical, happen all the time. It is important that we resolve disagreements and differing views constructively.
+* **Remember that we’re different.** The strength of our community comes from its diversity, people from a wide range of backgrounds. Different people have different perspectives on issues. Being unable to understand why someone holds a viewpoint doesn’t mean that they’re wrong. Don’t forget that it is human to err and blaming each other doesn’t get us anywhere. Instead, focus on helping to resolve issues and learning from mistakes.
+
+This code is not exhaustive or complete. It serves to distill our common understanding of a collaborative, shared environment, and goals. We expect it to be followed in spirit as much as in the letter.
+
+## Diversity Statement
+
+We encourage everyone to participate and are committed to building a community for all. Although we may not be able to satisfy everyone, we all agree that everyone is equal. Whenever a participant has made a mistake, we expect them to take responsibility for it. If someone has been harmed or offended, it is our responsibility to listen carefully and respectfully, and do our best to right the wrong.
+
+Although this list cannot be exhaustive, we explicitly honor diversity in age, gender, gender identity or expression, culture, ethnicity, language, national origin, political beliefs, profession, race, religion, sexual orientation, socioeconomic status, and technical ability. We will not tolerate discrimination based on any of the protected characteristics above, including participants with disabilities.
+
+## Reporting Issues
+
+If you experience or witness unacceptable behavior—or have any other concerns—please report it by contacting us via opensource@fb.com. All reports will be handled with discretion. In your report please include:
+
+* Your contact information.
+* Names (real, nicknames, or pseudonyms) of any individuals involved. If there are additional witnesses, please include them as well. Your account of what occurred, and if you believe the incident is ongoing. If there is a publicly available record (e.g. a mailing list archive or a public IRC logger), please include a link.
+* Any additional information that may be helpful.
+
+After filing a report, a representative will contact you personally. If the person who is harassing you is part of the response team, they will recuse themselves from handling your incident. A representative will then review the incident, follow up with any additional questions, and make a decision as to how to respond. We will respect confidentiality requests for the purpose of protecting victims of abuse.
+
+Anyone asked to stop unacceptable behavior is expected to comply immediately. If an individual engages in unacceptable behavior, the representative may take any action they deem appropriate, up to and including a permanent ban from our community without warning.
+
+_This Code Of Conduct follows the [template](http://todogroup.org/opencodeofconduct/) established by the [TODO Group](http://todogroup.org/)._

 # Contributing to React Native

-We want to make contributing to this project as easy and transparent as possible. Read on to learn more about our development process and how to propose bug fixes and improvements. The [How to Contribute](https://facebook.github.io/react-native/docs/contributing.html) guide on the website goes into more detail for each of these areas.
+<!-- generated_contributing_start -->
+React Native is one of Facebook's first open source projects that is both under very active development and is also being used to ship code to everybody using Facebook's mobile apps. If you're interested in contributing to React Native, hopefully this document makes the process for contributing clear.

-## Our Development Process
+## [Code of Conduct](https://code.facebook.com/codeofconduct)

-Most changes from engineers at Facebook will sync to [GitHub](https://github.com/facebook/react-native) through a bridge with Facebook's internal source control. Changes from the community are handled through GitHub pull requests. Once a change made on GitHub is approved, it will first be imported into Facebook's internal source control. The change will eventually sync back to GitHub as a single commit once it has passed Facebook's internal tests.
+Facebook has adopted a Code of Conduct that we expect project participants to adhere to. Please read [the full text](https://code.facebook.com/codeofconduct) so that you can understand what actions will and will not be tolerated.

-## Pull Requests
+## Get involved
+
+There are many ways to contribute to React Native, and many of them do not involve writing any code. Here's a few ideas to get started:
+
+* Simply start using React Native. Go through the [Getting Started](https://facebook.github.io/react-native/docs/getting-started.html) guide. Does everything work as expected? If not, we're always looking for improvements. Let us know by [opening an issue](https://facebook.github.io/react-native/docs/contributing.html#reporting-new-issues).
+* Look through the [open issues](https://github.com/facebook/react-native/issues). Provide workarounds, ask for clarification, or suggest labels. Help [triage issues](https://facebook.github.io/react-native/docs/contributing.html#triaging-issues-and-pull-requests).
+* If you find an issue you would like to fix, [open a pull request](https://facebook.github.io/react-native/docs/contributing.html#your-first-pull-request). Issues tagged as [_Good first issue_](https://github.com/facebook/react-native/labels/Good%20first%20issue) are a good place to get started.
+* Read through the [React Native docs](https://facebook.github.io/react-native/docs/getting-started.html). If you find anything that is confusing or can be improved, you can make edits by clicking the "EDIT" button in the top-right corner of most docs.
+* Browse [Stack Overflow](https://stackoverflow.com/questions/tagged/react-native) and answer questions. This will help you get familiarized with common pitfalls or misunderstandings, which can be useful when contributing updates to the documentation.
+* Take a look at the [features requested](https://react-native.canny.io/feature-requests) by others in the community and consider opening a pull request if you see something you want to work on.
+
+Contributions are very welcome. If you think you need help planning your contribution, please hop into [#react-native](https://discord.gg/0ZcbPKXt5bZjGY5n) and let people know you're looking for a mentor.
+
+Core contributors to React Native meet monthly and post their meeting notes on the [React Native blog](https://facebook.github.io/react-native/blog). You can also find ad hoc discussions in the [React Native Core Contributors](https://www.facebook.com/groups/reactnativeoss/) Facebook group.
+
+### Triaging issues and pull requests
+
+One great way you can contribute to the project without writing any code is to help triage issues and pull requests as they come in.
+
+* Ask for more information if the issue does not provide all the details required by the template.
+* Suggest [labels](https://github.com/facebook/react-native/labels) that can help categorize issues.
+* Flag issues that are stale or that should be closed.
+* Ask for test plans and review code.
+
+You can learn more about handling issues in the [maintainer's guide](docs/maintainers.html#handling-issues).
+
+## Our development process
+
+Some of the core team will be working directly on [GitHub](https://github.com/facebook/react-native). These changes will be public from the beginning. Other changesets will come via a bridge with Facebook's internal source control. This is a necessity as it allows engineers at Facebook outside of the core team to move fast and contribute from an environment they are comfortable in.
+
+When a change made on GitHub is approved, it will first be imported into Facebook's internal source control. The change will eventually sync back to GitHub as a single commit once it has passed all internal tests.
+
+### Branch organization
+
+We will do our best to keep `master` in good shape, with tests passing at all times. But in order to move fast, we will make API changes that your application might not be compatible with. We will do our best to [communicate these changes](https://github.com/facebook/react-native/releases) and version appropriately so you can lock into a specific version if need be.
+
+To see what changes are coming and provide better feedback to React Native contributors, use the [latest release candidate](https://facebook.github.io/react-native/versions.html) when possible. By the time a release candidate is released, the changes it contains will have been shipped in production Facebook apps for over two weeks.
+
+## Bugs
+
+We use [GitHub Issues](https://github.com/facebook/react-native/issues) for our public bugs. If you would like to report a problem, take a look around and see if someone already opened an issue about it. If you a are certain this is a new, unreported bug, you can submit a [bug report](https://facebook.github.io/react-native/docs/contributing.html#reporting-new-issues).
+
+If you have questions about using React Native, the [Community page](https://facebook.github.io/react-native/help.html) list various resources that should help you get started.
+
+We also have a [place where you can request features or enhancements](https://react-native.canny.io/feature-requests). If you see anything you'd like to be implemented, vote it up and explain your use case.
+
+## Reporting new issues
+
+When [opening a new issue](https://github.com/facebook/react-native/issues/new), always make sure to fill out the [issue template](https://raw.githubusercontent.com/facebook/react-native/master/.github/ISSUE_TEMPLATE.md). **This step is very important!** Not doing so may result in your issue getting closed. Don't take this personally if this happens, and feel free to open a new issue once you've gathered all the information required by the template.
+
+* **One issue, one bug:** Please report a single bug per issue.
+* **Provide a Snack:** The best way to get attention on your issue is to provide a reduced test case. You can use [Snack](https://snack.expo.io/) to demonstrate the issue.
+* **Provide reproduction steps:** List all the steps necessary to reproduce the issue. Provide a Snack or upload a sample project to GitHub. The person reading your bug report should be able to follow these steps to reproduce your issue with minimal effort.
+* **Try out the latest version:** Verify that the issue can be reproduced locally by updating your project to use [React Native from `master`](https://facebook.github.io/react-native/versions.html). The bug may have already been fixed!
+
+We're not able to provide support through GitHub Issues. If you're looking for help with your code, consider asking on [Stack Overflow](https://stackoverflow.com/questions/tagged/react-native) or reaching out to the community through [other channels](https://facebook.github.io/react-native/support.html).
+
+### Security bugs
+
+Facebook has a [bounty program](https://www.facebook.com/whitehat/) for the safe disclosure of security bugs. With that in mind, please do not file public issues; go through the process outlined on that page.
+
+## Pull requests
+
+### Your first pull request
+
+So you have decided to contribute code back to upstream by opening a pull request. You've invested a good chunk of time, and we appreciate it. We will do our best to work with you and get the PR looked at.
+
+Working on your first Pull Request? You can learn how from this free video series:
+
+[**How to Contribute to an Open Source Project on GitHub**](https://egghead.io/courses/how-to-contribute-to-an-open-source-project-on-github)
+
+We have a list of [beginner friendly issues](https://github.com/facebook/react-native/labels/Good%20first%20issue) to help you get your feet wet in the React Native codebase and familiar with our contribution process. This is a great place to get started.
+
+### Proposing a change
+
+If you would like to request a new feature or enhancement but are not yet thinking about opening a pull request, we have a [place to track feature requests](https://react-native.canny.io/feature-requests).
+
+If you intend to change the public API, or make any non-trivial changes to the implementation, we recommend [filing an issue](https://github.com/facebook/react-native/issues/new?title=%5BProposal%5D) that includes `[Proposal]` in the title. This lets us reach an agreement on your proposal before you put significant effort into it. These types of issues should be rare. If you have been contributing to the project long enough, you will probably already have access to the [React Native Core Contributors](https://www.facebook.com/groups/reactnativeoss/) Facebook Group, where this sort of discussion is usually held.
+
+If you're only fixing a bug, it's fine to submit a pull request right away but we still recommend to file an issue detailing what you're fixing. This is helpful in case we don't accept that specific fix but want to keep track of the issue.
+
+### Sending a pull request
+
+Small pull requests are much easier to review and more likely to get merged. Make sure the PR does only one thing, otherwise please split it.

 Please make sure the following is done when submitting a pull request:

-1. Fork the repo and create your branch from `master`.
-2. If you've added code that should be tested, add tests.
-3. If you've changed APIs, update the documentation.
-4. Ensure the test suite passes.
-5. Make sure your code lints.
-6. If you haven't already, complete the Contributor License Agreement ("CLA").
+1. Fork [the repository](https://github.com/facebook/react-native) and create your branch from `master`.
+2. Add the copyright notice to the top of any new files you've added.
+3. Describe your [**test plan**](https://facebook.github.io/react-native/docs/contributing.html#test-plan) in your pull request description. Make sure to [test your changes](https://facebook.github.io/react-native/docs/testing.html)!
+4. Make sure your code lints (`npm run lint`).
+5. If you haven't already, [sign the CLA](https://code.facebook.com/cla).

-## Contributor License Agreement ("CLA")
+All pull requests should be opened against the `master` branch. After opening your pull request, ensure [**all tests pass**](https://facebook.github.io/react-native/docs/contributing.html#contrinuous-integration-tests) on Circle CI. If a test fails and you believe it is unrelated to your change, leave a comment on the pull request explaining why.

-In order to accept your pull request, we need you to submit a CLA. You only need to do this once to work on any of Facebook's open source projects.
+> **Note:** It is not necessary to keep clicking `Merge master to your branch` on the PR page. You would want to merge master if there are conflicts or tests are failing. The Facebook-GitHub-Bot ultimately squashes all commits to a single one before merging your PR.

-Complete your CLA here: <https://code.facebook.com/cla>
+#### Test plan

-## Issues
+A good test plan has the exact commands you ran and their output, provides screenshots or videos if the pull request changes UI.

-We use GitHub issues to track public bugs. Please ensure your description is clear and has sufficient instructions to be able to reproduce the issue.
+* If you've added code that should be tested, add tests!
+* If you've changed APIs, update the documentation.

-Facebook has a [bounty program](https://www.facebook.com/whitehat/) for the safe disclosure of security bugs. In those cases, please go through the process outlined on that page and do not file a public issue.
+See [What is a Test Plan?](https://medium.com/@martinkonicek/what-is-a-test-plan-8bfc840ec171#.y9lcuqqi9) to learn more.

-## Coding Style
+#### Continuous integration tests

-We use Prettier to format our JavaScript code. This saves you time and energy as you can let Prettier fix up any formatting issues automatically through its editor integrations, or by manually running `npm run prettier`. We also use a linter to catch styling issues that may exist in your code. You can check the status of your code styling by simply running `npm run lint`.
+Make sure all **tests pass** on [Circle CI][circle]. PRs that break tests are unlikely to be merged. Learn more about [testing your changes here](https://facebook.github.io/react-native/docs/testing.html).

-However, there are still some styles that the linter cannot pick up, notably in Java or Objective-C code.
+[circle]: https://circleci.com/gh/facebook/react-native

-**Objective-C:**
+#### Breaking changes
+
+When adding a new breaking change, follow this template in your pull request:
+
+```
+### New breaking change here
+
+* **Who does this affect**:
+* **How to migrate**:
+* **Why make this breaking change**:
+* **Severity (number of people affected x effort)**:
+```
+
+If your pull request is merged, a core contributor will update the [list of breaking changes](https://github.com/facebook/react-native/wiki/Breaking-Changes) which is then used to populate the release notes.
+
+#### Copyright Notice for files
+
+Copy and paste this to the top of your new file(s):
+
+```JS
+/**
+ * Copyright (c) 2015-present, Facebook, Inc.
+ * All rights reserved.
+ *
+ * This source code is licensed under the BSD-style license found in the
+ * LICENSE file in the root directory of this source tree. An additional grant
+ * of patent rights can be found in the PATENTS file in the same directory.
+ */
+```
+
+If you've added a new module, add a `@providesModule <moduleName>` at the end of the comment. This will allow the haste package manager to find it.
+
+#### Contributor License Agreement (CLA)
+
+In order to accept your pull request, we need you to submit a CLA. You only need to do this once, so if you've done this for another Facebook open source project, you're good to go. If you are submitting a pull request for the first time, the Facebook GitHub Bot will reply with a link to the CLA form. You may also [complete your CLA here](https://code.facebook.com/cla).
+
+### What happens next?
+
+The core team will be monitoring for pull requests. Read [what to expect from maintainers](https://facebook.github.io/react-native/docs/maintainers.html#handling-pull-requests) to understand what may happen after you open a pull request.
+
+## Style Guide
+
+Our linter will catch most styling issues that may exist in your code. You can check the status of your code styling by simply running `npm run lint`.
+
+However, there are still some styles that the linter cannot pick up.
+
+### Code Conventions
+
+#### General
+
+* **Most important: Look around.** Match the style you see used in the rest of the project. This includes formatting, naming things in code, naming things in documentation.
+* Add trailing commas,
+* 2 spaces for indentation (no tabs)
+* "Attractive"
+
+#### JavaScript
+
+* Use semicolons;
+* ES6 standards
+* Prefer `'` over `"`
+* Do not use the optional parameters of `setTimeout` and `setInterval`
+* 80 character line length
+
+#### JSX
+
+* Prefer `"` over `'` for string literal props
+* When wrapping opening tags over multiple lines, place one prop per line
+* `{}` of props should hug their values (no spaces)
+* Place the closing `>` of opening tags on the same line as the last prop
+* Place the closing `/>` of self-closing tags on their own line and left-align them with the opening `<`
+
+#### Objective-C

 * Space after `@property` declarations
 * Brackets on *every* `if`, on the *same* line

Mike Grabowski	56a2d6d720	[0.54.4] Bump version numbers	2018-03-28 19:09:37 +02:00
Janic Duplessis	0ba6ed897a	Fix blob response parsing for empty body on iOS Summary: We currently handle empty body poorly in the iOS blob implementation, this happens because of an early return that cause the blob response to not be processed by the blob module, resulting in an empty string as the body instead of a blob object.

If this PR fixes an issue, type "Fixes #issueNumber" to automatically close the issue when the PR is merged. --> Commit https://github.com/facebook/react-native/commit/7891805d22e3fdc821961ff0ccc5c450c3d625c8 broke the previous behavior of `ReadableNativeMap.toHashMap()` for nested maps and arrays. Previously, all nested `ReadableNativeMap`s and `ReadableNativeArray`s were recursively converted to `HashMap`s and `ArrayList`s, but this is lost when only `getLocalMap()` is returned. <!-- Required: Write your test plan here. If you changed any code, please provide us with clear instructions on how you verified your changes work. Bonus points for screenshots and videos! --> Call `ReadableNativeMap.toHashMap()` on a map with values of type `ReadableNativeMap` and `ReadableNativeArray`. Verify the returned hash map has these converted to `HashMap` and `ArrayList`, respectively. <!-- Does this PR require a documentation change?

Josh Hargreaves	53c1a4cc7b	Fix crashes onKeyPress Android Summary: There appear to be two different types of crashes related to the recent addition of `onKeyPress` on Android introduce in `0.53`. This PR addresses the cause of both of them. Firstly, it seems possible to get an `indexOutOfBoundsException` with some 3rd-party keyboards as observed in https://github.com/facebook/react-native/issues/17974 & https://github.com/facebook/react-native/issues/17922. I have simplified the backspace determining logic slightly, and also put in an explicit check for zero case so it is not possible to get an indexOutOfBoundsException & it should make sense in the context of the onKeyPress logic. Secondly, it appears that `EditText#onCreateInputConnection` can return null. In this case, if we set `null` to be the target of our subclass of `ReactEditTextInputConnectionWrapper`, we will see the crashes as seen [here](https://github.com/facebook/react-native/issues/17974#issuecomment-368471737), whereby any of methods executed in the `InputConnection` interface can result in a crash. It's hard to reason about the state when `null` is returned from `onCreateInputConnection`, however I would might reason that any soft keyboard input cannot update the `EditText` with a `null` `input connection`, as there is no way of interfacing with the `EditText`. I'm am not sure, if there is a later point where we might return/set this input connection at a later point? As without the `InputConnection` onKeyPress will not work. But for now, this will fix this crash at least. I have not managed to reproduce these crashes myself yet, but users have confirmed that the `indexOutOfBounds` exception is fixed with the 'zero' case and has been confirmed on the respective issues https://github.com/facebook/react-native/issues/17974#issuecomment-368471737. For the `null` inputConnection target case, I have verified that explicitly setting the target as null in the constructor of `onCreateInputConnection` results in the same stack trace as the one linked. Here is also a [reference](https://github.com/stripe/stripe-android/pull/392/files#diff-6cc1685c98457d07fd4e2dd83f54d5bb) to the same issue closed with the same fix for another project on github. It is also important to verify that the behavior of `onKeyPress` still functions the same after this change, which can be verified by running the RNTesterProject and the `KeyboardEvents` section in `InputText`. The cases to check that I think are important to check are: - Cursor at beginning of input & backspace - Return key & return key at beginning of input - Select text then press delete - Selection then press a key - Space key - Different keyboard types This should not be a breaking change.
