QUESTION

Fixing git HTTPS Error: "bad key length" on macOS 12

Asked 2022-Mar-29 at 17:34

I am using a company-hosted (Bitbucket) git repository that is accessible via HTTPS. Accessing it (e.g. git fetch) worked using macOS 11 (Big Sur), but broke after an update to macOS 12 Monterey. *

After the update of macOS to 12 Monterey my previous git setup broke. Now I am getting the following error message:

1$ git fetch
2fatal: unable to access 'https://.../':
3error:06FFF089:digital envelope routines:CRYPTO_internal:bad key length
4

For what it's worth, using curl does not work either:

1$ git fetch
2fatal: unable to access 'https://.../':
3error:06FFF089:digital envelope routines:CRYPTO_internal:bad key length
4$ curl --insecure -L -v https://...

21* Closing connection 0
22curl: (35) error:06FFF089:digital envelope routines:CRYPTO_internal:bad key length
23

Accessing the same HTTPS-source via Safari or Firefox works.

As far as I understand, the underlying error "bad key length" error is coming from OpenSSL/LibreSSL, this would be consistent with both git and curl failing after an OS upgrade.

This is the output from openssl:

1$ git fetch
2fatal: unable to access 'https://.../':

I did try to add the server's certificates into a custom pem file and setting http.sslCAInfo, but that didn't work. As a workaround, I am currently using a proxy that decrypts/re-encrypts HTTPS traffic.

How do I configure git (or all LibreSSL users) to accept the server's certificate?

ANSWER

Answered 2021-Nov-02 at 07:12

Unfortunately I can't provide you with a fix, but I've found a workaround for that exact same problem (company-hosted bitbucket resulting in exact same error). I also don't know exactly why the problem occurs, but my best guess would be that the libressl library shipped with Monterey has some sort of problem with specific (?TLSv1.3) certs. This guess is because the brew-installed openssl v1.1 and v3 don't throw that error when executed with /opt/homebrew/opt/openssl/bin/openssl s_client -connect ...:443

To get around that error, I've built git from source built against different openssl and curl implementations:

install autoconf, openssl and curl with brew (I think you can select the openssl lib you like, i.e. v1.1 or v3, I chose v3)
clone git version you like, i.e. git clone --branch v2.33.1 https://github.com/git/git.git
cd git
make configure (that is why autoconf is needed)
execute LDFLAGS="-L/opt/homebrew/opt/openssl@3/lib -L/opt/homebrew/opt/curl/lib" CPPFLAGS="-I/opt/homebrew/opt/openssl@3/include -I/opt/homebrew/opt/curl/include" ./configure --prefix=$HOME/git (here LDFLAGS and CPPFLAGS include the libs git will be built against, the right flags are emitted by brew on install success of curl and openssl; --prefix is the install directory of git, defaults to /usr/local but can be changed)
make install
ensure to add the install directory's subfolder /bin to the front of your $PATH to "override" the default git shipped by Monterey
restart terminal
check that git version shows the new version

This should help for now, but as I already said, this is only a workaround, hopefully Apple fixes their libressl fork ASAP.

If you are upgrading your Laravel 8 project to Laravel 9 by importing your existing application code into a totally new Laravel 9 application skeleton, you may need to update your application's "trusted proxy" middleware.

Within your app/Http/Middleware/TrustProxies.php file, update use Fideloper\Proxy\TrustProxies as Middleware to use Illuminate\Http\Middleware\TrustProxies as Middleware.

Next, within app/Http/Middleware/TrustProxies.php, you should update the $headers property definition:

// Before...

protected $headers = Request::HEADER_X_FORWARDED_ALL;

// After...

ANSWER

Answered 2021-Aug-04 at 20:48

There are two issues here:

Oracle Database is not supported on ARM processors, only Intel. See here: https://github.com/oracle/docker-images/issues/1814
Oracle Database Docker images are only supported with Oracle Linux 7 or Red Hat Enterprise Linux 7 as the host OS. See here: https://github.com/oracle/docker-images/tree/main/OracleDatabase/SingleInstance

Oracle Database ... is supported for Oracle Linux 7 and Red Hat Enterprise Linux (RHEL) 7. For more details please see My Oracle Support note: Oracle Support for Database Running on Docker (Doc ID 2216342.1)

The referenced My Oracle Support Doc ID goes on to say that the database binaries in their Docker image are built specifically for Oracle Linux hosts, and will also work on Red Hat. That's it.

Because Docker provides process level virtualization it still pulls kernel and other OS libraries from the underlying host OS. A Docker image built for Oracle Linux needs an Oracle Linux host; it doesn't bring the Oracle Linux OS with it. Only Oracle Linux or Red Hat Linux are supported for any Oracle database Linux installation, with or without Docker. Ubuntu, Mac OS, Debian, or any other *NIX flavor will not provide predictable reliable results, even if it is hacked into working or the processes appear to work normally.

QUESTION

How to configure proxy in emulators in new versions of Android Studio?

Asked 2022-Feb-23 at 14:14

Problem Description

I need to configure the proxy manually in my emulator through Android Studio. From the official Android documentation, it is suggested that this change can be made in the "settings" tab of the emulator's extended controls. The problem is that it seems to me that this documentation is outdated, as this setting is no longer displayed in the "settings" tab of the Android Studio emulators' extended controls.

After a while trying to find solutions to this problem, I saw that an emulator running outside android studio provides these options. To run a standalone Android Studio emulator see the official documentation or simply enter the command:

In my case I'm using an avd named PIXEL 4 API 30, so the command will be emulator -avd PIXEL_4_API_30. If you are on Windows you may have problems running this command so I suggest you see this.

Edit

The solution proposed by @Inliner also solves this problem.

QUESTION

Uvicorn async workers are still working synchronously

Asked 2022-Feb-07 at 18:39

Question in short

I have migrated my project from Django 2.2 to Django 3.2, and now I want to start using the possibility for asynchronous views. I have created an async view, setup asgi configuration, and run gunicorn with a Uvicorn worker. When swarming this server with 10 users concurrently, they are served synchronously. What do I need to configure in order to serve 10 concurrent users an async view?

Question in detail

This is what I did so far in my local environment:

I am working with Django 3.2.10 and Python 3.9.
I have installed gunicorn and uvicorn through pip
I have created an asgi.py file with the following contents

1    import os
2    from django.core.asgi import get_asgi_application
3    os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'MyService.settings.local')
4    application = get_asgi_application()
5

I have created a view with the following implementation, and connected it in urlpatterns:

1    import os
2    from django.core.asgi import get_asgi_application
3    os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'MyService.settings.local')
4    application = get_asgi_application()
5    import asyncio
6    import json
7    from django.http import HttpResponse
8    
9    async def async_sleep(request):
10        await asyncio.sleep(1)
11        return HttpResponse(json.dumps({'mode': 'async', 'time': 1).encode())
12

I run locally a gunicorn server with a Uvicorn worker:

1    import os
2    from django.core.asgi import get_asgi_application
3    os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'MyService.settings.local')
4    application = get_asgi_application()
5    import asyncio
6    import json
7    from django.http import HttpResponse
8    
9    async def async_sleep(request):
10        await asyncio.sleep(1)
11        return HttpResponse(json.dumps({'mode': 'async', 'time': 1).encode())

21

I hit the API from a local client once. After 1 second, I get a 200 OK, as expected.
I set up a locust server to spawn concurrent users. When I let it make requests with 1 concurrent user, every 1 second an API call is completed.
When I let it make requests with 10 concurrent users, every 1 second an API call is completed. All other requests are waiting.

This last thing is not what I expect. I expect the worker, while sleeping asynchronously, to pick up the next request already. Am I missing some configuration?

I also tried it by using Daphne instead of Uvicorn, but with the same result.

Locust

This is how I have set up my locust.

Start a new virtualenv
pip install locust
Create a locustfile.py with the following content:

1    import os
2    from django.core.asgi import get_asgi_application
3    os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'MyService.settings.local')

9    async def async_sleep(request):
10        await asyncio.sleep(1)
11        return HttpResponse(json.dumps({'mode': 'async', 'time': 1).encode())

When running the gunicorn command, you can try to add workers parameter with using options -w or --workers.

It defaults to 1 as stated in the gunicorn documentation. You may want to try to increase that value.

Example usage:

1    import os
2    from django.core.asgi import get_asgi_application
3    os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'MyService.settings.local')
4    application = get_asgi_application()

6    import json
7    from django.http import HttpResponse
8    
9    async def async_sleep(request):
10        await asyncio.sleep(1)
11        return HttpResponse(json.dumps({'mode': 'async', 'time': 1).encode())

Fatal Android 12: Exception: startForegroundService() not allowed due to mAllowStartForeground false

Asked 2022-Jan-11 at 12:43

I noticed one exception (Firebase Crashlytics) for Pixel 5 and Pixel 4a (both on Android 12), no other devices, happened only two times, one time for each device.

What does it mean? Android 11 and 12 have the same rules for working with foreground services, but there are no issues with Android 11. Is this a bug of Pixel?

Answered 2022-Jan-11 at 12:43

Apps that target Android 12 (API level 31) or higher can't start foreground services while running in the background, except for a few special cases. If an app tries to start a foreground service while the app is running in the background, and the foreground service doesn't satisfy one of the exceptional cases, the system throws a ForegroundServiceStartNotAllowedException.

Exemptions from background start restrictions

In the following situations, your app can start foreground services even while your app is running in the background:

Your app transitions from a user-visible state, such as an activity.
Your app can start an activity from the background, except for the case where the app has an activity in the back stack of an existing task.
Your app receives a high-priority message using Firebase Cloud Messaging.
The user performs an action on a UI element related to your app. For example, they might interact with a bubble, notification, widget, or activity.
Your app invokes an exact alarm to complete an action that the user requests.
Your app is the device's current input method.
Your app receives an event that's related to geofencing or activity recognition transition.
After the device reboots and receives the ACTION_BOOT_COMPLETED, ACTION_LOCKED_BOOT_COMPLETED, or ACTION_MY_PACKAGE_REPLACED intent action in a broadcast receiver.

I'm adding the way to reproduce this issue, and fixes to this problem, because I did not find any documentation about this on StackOverflow when I searched for it.

ANSWER

Answered 2021-Oct-17 at 13:49

How to reproduce the crash

Step 1. Update your targetSdkVersion and compileSdkVersion to SDK 31.

Step 2. Try to run any Foreground service when your app is in background. In my case, it was the widget's onUpdate method being called after updatePeriodMillis time, which will start a Foreground service, which updates the data by fetching appropriate information from internet.

Remember: The background execution limits added in Android 8.0 have nothing to do with this problem. This limitation/exception was added in Android 12/SDK 31 - Source.

What is this exception, and why was it added?

These special cases are:

Your app transitions from a user-visible state, such as an activity.
Your app can start an activity from the background, except for the case where the app has an activity in the back stack of an existing task.
Your app receives a high-priority message using Firebase Cloud Messaging.
The user performs an action on a UI element related to your app. For example, they might interact with a bubble, notification, widget, or activity.
Your app invokes an exact alarm to complete an action that the user requests.
Your app is the device's current input method.
Your app receives an event that's related to geofencing or activity recognition transition.
After the device reboots and receives the ACTION_BOOT_COMPLETED, ACTION_LOCKED_BOOT_COMPLETED, or ACTION_MY_PACKAGE_REPLACED intent action in a broadcast receiver.
Your app receives the ACTION_TIMEZONE_CHANGED, ACTION_TIME_CHANGED, or ACTION_LOCALE_CHANGED intent action in a broadcast receiver.
Your app receives a Bluetooth broadcast that requires the BLUETOOTH_CONNECT or BLUETOOTH_SCAN permissions.
Apps with certain system roles or permission, such as device owners and profile owners.
Your app uses the Companion Device Manager and declares the REQUEST_COMPANION_START_FOREGROUND_SERVICES_FROM_BACKGROUND permission or the REQUEST_COMPANION_RUN_IN_BACKGROUND permission. Whenever possible, use REQUEST_COMPANION_START_FOREGROUND_SERVICES_FROM_BACKGROUND.
The user turns off battery optimizations for your app. You can help users find this option by sending them to your app's App info page in system settings. To do so, invoke an intent that contains the ACTION_IGNORE_BATTERY_OPTIMIZATION_SETTINGS intent action.

Possible solutions Solution 1

This will work for a while in Play Store until Google makes it mandatory to upgrade to API level 31.

Currently, starting November 2021 all apps must target API Level 30 and above. So if you're using API Level 31 for your app, downgrading your compileSdkVersion & targetSdkVersion to API Level 30 should fix the issue (atleast for a while).

Solution 2 For time-sensitive work

If you were using Foreground service to do work that is time sensitive, start Foreground services within an exact alarm. Check out more about this from documentation here -> Set an exact alarm.

For time-insensitive/expedited work

This is the solution that I ended up using for my app. Use WorkManager to schedule and start the background work. Check out more about this from documentation here -> Schedule expedited work.

You can know more about WorkManager here -> WorkManager

Github Repo for WorkManager samples -> WorkManager Samples

I added this answer specifically because searching for this exception does not bring up any resources to know why the service behaves differently on Android 12. All this is present in Google's documentation, and always remember to check the behaviour changes from the doc.

Everything related to this change can be found here -> Android 12 Behavior Changes, specifically within the Foreground Service launch restrictions.

QUESTION

"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:

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.
