QUESTION

Invalid options object. Dev Server has been initialized using an options object that does not match the API schema

Asked 2022-Mar-28 at 21:08

I have been stock on this error on my project when I add "proxy": "http://localhost:6000" in my package.json.

This is the error response after yarn start.

Invalid options object. Dev Server has been initialized using an options object that does not match the API schema.

options.allowedHosts[0] should be a non-empty string. error Command failed with exit code 1. info Visit https://yarnpkg.com/en/docs/cli/run for documentation about this command.

But everything is fine when I remove the "proxy": "http://localhost:6000".

This is on my package.json:

Here is a workaround. Delete "proxy": "http://localhost:6000". Install package http-proxy-middleware with command npm install http-proxy-middleware --save. Create a file setupProxy.js inside your src folder. Add these lines inside:

const { createProxyMiddleware } = require('http-proxy-middleware');

module.exports = function(app) {
  app.use(
    '/api',
    createProxyMiddleware({
      target: 'http://localhost:6000',
      changeOrigin: true,
    })
  );
};

Now, run your app. It should work.

Error: require() of ES modules is not supported when importing node-fetch

Use ESM syntax, also use one of these methods before running the file.

specify "type":"module" in package.json
Or use this flag --input-type=module when running the file
Or use .mjs file extension

QUESTION

The unauthenticated git protocol on port 9418 is no longer supported

Asked 2022-Mar-27 at 13:23

I have been using github actions for quite sometime but today my deployments started failing. Below is the error from github action logs

Command: git
Arguments: ls-remote --tags --heads git://github.com/adobe-webplatform/eve.git
Directory: /home/runner/work/stackstream-fe/stackstream-fe

Upon investigation, it appears that below section in my yml file is causing the issue.

First, this error message is indeed expected on Jan. 11th, 2022.
See "Improving Git protocol security on GitHub".

January 11, 2022 Final brownout.

This is the full brownout period where we’ll temporarily stop accepting the deprecated key and signature types, ciphers, and MACs, and the unencrypted Git protocol.
This will help clients discover any lingering use of older keys or old URLs.

Second, check your package.json dependencies for any git:// URL, as in this example, fixed in this PR.

As noted by Jörg W Mittag:

There was a 4-month warning.
The entire Internet has been moving away from unauthenticated, unencrypted protocols for a decade, it's not like this is a huge surprise.

Personally, I consider it less an "issue" and more "detecting unmaintained dependencies".

Plus, this is still only the brownout period, so the protocol will only be disabled for a short period of time, allowing developers to discover the problem.

The permanent shutdown is not until March 15th.

For GitHub Actions:

As in actions/checkout issue 14, you can add as a first step:

    - name: Fix up git URLs
      run: echo -e '[url "https://github.com/"]\n  insteadOf = "git://github.com/"' >> ~/.gitconfig

That will change any git://github.com/ into https://github.com/.

For local projects

For all your repositories, you can set:

git config --global url."https://github.com/".insteadOf git://github.com/

You can also use SSH, but GitHub Security reminds us that, as of March 15th, 2022, GitHub stopped accepting DSA keys. RSA keys uploaded after Nov 2, 2021 will work only with SHA-2 signatures.
The deprecated MACs, ciphers, and unencrypted Git protocol are permanently disabled.

So this (with the right key) would work:

git config --global url."git@github.com:".insteadOf git://github.com/

That will change any git://github.com/ (unencrypted Git protocol) into git@github.com: (SSH URL).

The new version, of react-native-gesture-handler send warning if you use an old API version, but also if one of your package/library use it.

To disable the warning, you can ignore logs.

in your app.js / app.tsx

import { LogBox } from 'react-native';

LogBox.ignoreLogs([
  "[react-native-gesture-handler] Seems like you\'re using an old API with gesture components, check out new Gestures system!",
]);

Terraform AWS Provider Error: Value for unconfigurable attribute. Can't configure a value for "acl": its value will be decided automatically

Terraform AWS Provider is upgraded to version 4.0.0 which is published on 10 February 2022.

Major changes in the release include:

Version 4.0.0 of the AWS Provider introduces significant changes to the aws_s3_bucket resource.
Version 4.0.0 of the AWS Provider will be the last major version to support EC2-Classic resources as AWS plans to fully retire EC2-Classic Networking. See the AWS News Blog for additional details.
Version 4.0.0 and 4.x.x versions of the AWS Provider will be the last versions compatible with Terraform 0.12-0.15.

The reason for this change by Terraform is as follows: To help distribute the management of S3 bucket settings via independent resources, various arguments and attributes in the aws_s3_bucket resource have become read-only. Configurations dependent on these arguments should be updated to use the corresponding aws_s3_bucket_* resource. Once updated, new aws_s3_bucket_* resources should be imported into Terraform state.

So, I updated my code accordingly by following the guide here: Terraform AWS Provider Version 4 Upgrade Guide | S3 Bucket Refactor

The new working code looks like this:

resource "aws_s3_bucket" "this" {
  bucket = "${var.project}-${var.environment}-ssm-parameter-store-backups-bucket"

  tags = {
    Name        = "${var.project}-${var.environment}-ssm-parameter-store-backups-bucket"
    Environment = var.environment
  }
}

resource "aws_s3_bucket_acl" "this" {
  bucket = aws_s3_bucket.this.id
  acl    = "private"
}

resource "aws_s3_bucket_server_side_encryption_configuration" "this" {
  bucket = aws_s3_bucket.this.id

  rule {
    apply_server_side_encryption_by_default {
      kms_master_key_id = data.aws_kms_key.s3.arn
      sse_algorithm     = "aws:kms"
    }
  }
}

resource "aws_s3_bucket_lifecycle_configuration" "this" {
  bucket = aws_s3_bucket.this.id

  rule {
    id     = "backups"
    status = "Enabled"

    filter {
      prefix = "backups/"
    }

    transition {
      days          = 90
      storage_class = "GLACIER_IR"
    }

    transition {
      days          = 180
      storage_class = "DEEP_ARCHIVE"
    }

    expiration {
      days = 365
    }
  }
}

If you don't want to upgrade your Terraform AWS Provider version to 4.0.0, you can use the existing or older version by specifying it explicitly in the code as below:

terraform {
  required_version = "~> 1.0.11"
  required_providers {
    aws  = "~> 3.73.0"
  }
}

From v13 angular doesn't use tslint anymore due to deprecation.

Run ng add @angular-eslint/schematics to add eslint to your application.

It will use tslint-to-eslint-config to migrate you to eslint automatically.

It will generate a .eslintrc.json file and migrate tslint.json to it.

Nothing else is needed to be done.

QUESTION

Why is a segmentation fault not recoverable?

Asked 2021-Dec-13 at 08:36

Following a previous question of mine, most comments say "just don't, you are in a limbo state, you have to kill everything and start over". There is also a "safeish" workaround.

What I fail to understand is why a segmentation fault is inherently nonrecoverable.

The moment in which writing to protected memory is caught - otherwise, the SIGSEGV would not be sent.

If the moment of writing to protected memory can be caught, I don't see why - in theory - it can't be reverted, at some low level, and have the SIGSEGV converted to a standard software exception.

Please explain why after a segmentation fault the program is in an undetermined state, as very obviously, the fault is thrown before memory was actually changed (I am probably wrong and don't see why). Had it been thrown after, one could create a program that changes protected memory, one byte at a time, getting segmentation faults, and eventually reprogramming the kernel - a security risk that is not present, as we can see the world still stands.

When exactly does a segmentation fault happen (= when is SIGSEGV sent)?
Why is the process in an undefined behavior state after that point?
Why is it not recoverable?
Why does this solution avoid that unrecoverable state? Does it even?

ANSWER

Answered 2021-Dec-10 at 15:05

When exactly does segmentation fault happen (=when is SIGSEGV sent)?

When you attempt to access memory you don’t have access to, such as accessing an array out of bounds or dereferencing an invalid pointer. The signal SIGSEGV is standardized but different OS might implement it differently. "Segmentation fault" is mainly a term used in *nix systems, Windows calls it "access violation".

Why is the process in undefined behavior state after that point?

Because one or several of the variables in the program didn’t behave as expected. Let’s say you have some array that is supposed to store a number of values, but you didn’t allocate enough room for all them. So only those you allocated room for get written correctly, and the rest written out of bounds of the array can hold any values. How exactly is the OS to know how critical those out of bounds values are for your application to function? It knows nothing of their purpose.

Furthermore, writing outside allowed memory can often corrupt other unrelated variables, which is obviously dangerous and can cause any random behavior. Such bugs are often hard to track down. Stack overflows for example are such segmentation faults prone to overwrite adjacent variables, unless the error was caught by protection mechanisms.

If we look at the behavior of "bare metal" microcontroller systems without any OS and no virtual memory features, just raw physical memory - they will just silently do exactly as told - for example, overwriting unrelated variables and keep on going. Which in turn could cause disastrous behavior in case the application is mission-critical.

Why is it not recoverable?

Because the OS doesn’t know what your program is supposed to be doing.

Though in the "bare metal" scenario above, the system might be smart enough to place itself in a safe mode and keep going. Critical applications such as automotive and med-tech aren’t allowed to just stop or reset, as that in itself might be dangerous. They will rather try to "limp home" with limited functionality.

Why does this solution avoid that unrecoverable state? Does it even?

That solution is just ignoring the error and keeps on going. It doesn’t fix the problem that caused it. It’s a very dirty patch and setjmp/longjmp in general are very dangerous functions that should be avoided for any purpose.

We have to realize that a segmentation fault is a symptom of a bug, not the cause.

"Theming Icons" functionality crashes live wallpapers on Android 12

Asked 2021-Dec-07 at 22:23

I recently noticed that my live wallpaper apps are crashing when users try to set the newly introduced "Theming Icons" functionality on Android 12. This new functionality calculates a palette of colors from the user's current static wallpaper and uses this palette to color some of the other apps icons (a feature of the new "Material You" design). But for some reason when it operates on a live wallpaper it crashes the app with the following log:

Fatal Exception: java.lang.NullPointerException: Attempt to invoke virtual method 'android.graphics.Bitmap android.graphics.drawable.BitmapDrawable.getBitmap()' on a null object reference

At this moment I can observe this crash only on Samsung Galaxy S21 / S21 Ultra phones but it will be present on many more phones as users update their system to Android 12.

Currently, I cannot reproduce this crash because I don't own a Galaxy S21 and the Android Studio emulator still misses the "Theming Icons" option (maybe because this functionality is currently still in beta).

Does anybody have any clue on how to solve this catastrophic problem? Any help is greatly appreciated!

Update November 18: I was able to test the new "Themed icon" feature on the Android Studio Emulator (on the newly introduced "SV2" release). This release is really buggy but I was not able to reproduce a similar crash. It makes me think that this crash is exclusive to Samsung phones.

I tried to test some Galaxy S21 devices from the publicly available phones at the "Galaxy Mobile - Remote Test Lab" site, but they implement a beta version of Android 12 where the Themed Icon feature is not available.

I want to generate a complete crash report (log + video) to send to Samsung but I still can't find a Galaxy S21 with Android 12 installed (the Android 12 system update started on November 15 for Galaxy S21 phones). In the meantime, the crash reports are exploding as many more users are updating their phones to Android 12...Such a shame!

For a while I was looking for a similar problem in reviews of popular live wallpapers. I found similar reviews only for one application. I updated my phone today. All my live wallpapers stopped working as expected. Then I installed "Earth & Moon" and this app works fine. It means that we are doing something wrong or, on the contrary, we are not doing something :) In the near future I will begin to investigate this problem.
