Python/Docker ImportError: cannot import name 'json' from itsdangerous

Asked 2022-Mar-31 at 12:49

I am trying to get a Flask and Docker application to work but when I try and run it using my docker-compose up command in my Visual Studio terminal, it gives me an ImportError called ImportError: cannot import name 'json' from itsdangerous. I have tried to look for possible solutions to this problem but as of right now there are not many on here or anywhere else. The only two solutions I could find are to change the current installation of MarkupSafe and itsdangerous to a higher version: https://serverfault.com/questions/1094062/from-itsdangerous-import-json-as-json-importerror-cannot-import-name-json-fr and another one on GitHub that tells me to essentially change the MarkUpSafe and itsdangerous installation again https://github.com/aws/aws-sam-cli/issues/3661, I have also tried to make a virtual environment named veganetworkscriptenv to install the packages but that has also failed as well. I am currently using Flask 2.0.0 and Docker 5.0.0 and the error occurs on line eight in vegamain.py.

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

Android Studio Disconnects From Physical Device

Asked 2022-Mar-06 at 15:11

Android Studio Bumblebee (2021.1.1) was released stably on 25 January 2022 bundled with a new Device Manager (accompanying new support for Android 11+ device debugging over WIFI). I jumped on this stable release, updating from Android Studio Arctic Fox (2020.3.1 Patch 4).

Unfortunately however, since updating, physical devices/handsets don't remain connected to Android Studio for the purpose of debugging. I can confirm that the issue was introduced from Android Studio Bumblebee onwards (occurring in Beta and Canary builds also). I've reproduced the issue on Android Studio Bumblebee (Stable), Chipmunk (Beta), and Dolphin (Canary), but Android Studio Arctic Fox (superseded Stable) continues to work just fine.

The issue occurs soon after opening Android Studio (Bumblebee+) with one of my physical devices connected. Everything appears fine initially and I may even have enough time to deploy my project to the handset, before the device disappears from Android Studio (as if I'd physically disconnected the USB cable from my computer or from the handset itself).

I've tried a fair few things in an attempt to determine a root cause. These include testing:

With different USB cables.
With different handsets (both varying makes and models).
With various versions of the Android Studio IDE (as mentioned above).
Plugging the USB cables into different USB ports on my computer.
Rebooting handsets and my computer.
Restarting Android Studio.
Invalidating caches and restarting Android Studio.
adb kill-server then adb start-server.
Revoking/reaccepting USB debugging authorization.
Reinstalled build tools/platform tools, and ADB.
A great number of further possibilities, to no avail.

I searched and read through remotely similar issues, including (but not limited to) these:

This particular comment in one of the above issues clued me onto a possible root cause:

I have been fighting for a few days with adb not seeing my device. After trying many other posted solutions, I discovered that the issue was with Chrome also trying to connect its debugger to a web view. If Chrome is connected using chrome://inspect, then adb seems to disconnect. Quitting Chrome resolves the issue. Then I can connect with Android Studio and then restart Chrome and reconnect. Hope this helps someone else.

However I've been unable to do anything with the above discovery, other than close Google Chrome, and hope for the best. Obviously this isn't an ideal solution. It appears as though the moment Google Chrome shows the connected physical device in the chrome://inspect/#devices page, the physical device promptly becomes unavailable through Android Studio.

I've jumped back to Android Studio Arctic Fox (2020.3.1 Patch 4) for the moment, however this brings with it other issues (my current core project targets the latest SDK version, which requires the updated IDE).

Absolutely any help with this would be insanely appreciated. I've exhausted just about every avenue that I can think of!

Ideas on how to get around Windows 11 ARM not supporting IIS

Asked 2022-Feb-28 at 21:25

My new Macbook Pro running on an M1 Max (ARM) chip just came in. I installed Parallels and Windows 11 Preview for ARM, and Visual Studio installs / launches / builds my solution beautifully. Unfortunately the turn windows features on or off dialog doesn't have the option for installing IIS, and others have posted that this is not supported in Windows 11 for ARM.

Our dev team runs multiple ASP.NET Core 3.1 websites locally under IIS using subdomains, e.g.: https://auth-dev.mydomain.com, https://web-dev.mydomain.com, https://webapi-dev.mydomain.com. This was easy to set up in IIS using the bindings dialog, I could specify for port 443 (https) to use a certain subdomain and our dev SSL certificate.

Now I need to figure out how to make this work on Windows 11 ARM. Developing on an inferior non-Macbook Pro laptop doesn't seem like a great solution for .NET devs, I have to assume others with M1 chip Macbook Pros have run into this same issue. What are my options?

I first started looking into using IIS Express, but it seems like every website has to run on a different port, whereas I need them all to run on port 80 (just with different subdomains.) I'd be fine with them running on different ports if there was a way to forward those various ports to the subdomains, but it doesn't seem like the windows HOSTS file supports that.

I also looked into using the Apache web server for Windows, but I read somewhere that it doesn't support running ASP.NET Core apps.

ANSWER

Answered 2021-Dec-21 at 21:47

The issue is that when connecting in a docker-compose network, you have to connect to the hostname of the container, in this case db.

You could also use the other container's IP but would take additional amount of work, it's simpler to just use the hostname.

In other words, you have the wrong connection string, I got this as well when connecting to localhost

ANSWER

Answered 2021-Dec-13 at 06:33

You can see the cost of instructions on most mainstream architecture here and there. Based on that and assuming you use for example an Intel Skylake processor, you can see that one 32-bit imul instruction can be computed per cycle but with a latency of 3 cycles. In the optimized code, 2 lea instructions (which are very cheap) can be executed per cycle with a 1 cycle latency. The same thing apply for the sal instruction (2 per cycle and 1 cycle of latency).

This means that the optimized version can be executed with only 2 cycle of latency while the first one takes 3 cycle of latency (not taking into account load/store instructions that are the same). Moreover, the second version can be better pipelined since the two instructions can be executed for two different input data in parallel thanks to a superscalar out-of-order execution. Note that two loads can be executed in parallel too although only one store can be executed in parallel per cycle. This means that the execution is bounded by the throughput of store instructions. Overall, only 1 value can only computed per cycle. AFAIK, recent Intel Icelake processors can do two stores in parallel like new AMD Ryzen processors. The second one is expected to be as fast or possibly faster on the chosen use-case (Intel Skylake processors). It should be significantly faster on very recent x86-64 processors.

Note that the lea instruction is very fast because the multiply-add is done on a dedicated CPU unit (hard-wired shifters) and it only supports some specific constant for the multiplication (supported factors are 1, 2, 4 and 8, which mean that lea can be used to multiply an integer by the constants 2, 3, 4, 5, 8 and 9). This is why lea is faster than imul/mul.

UPDATE (v2):

I can reproduce the slower execution with -O2 using GCC 11.2 (on Linux with a i5-9600KF processor).

The main source of source of slowdown comes from the higher number of micro-operations (uops) to be executed in the -O2 version certainly combined with the saturation of some execution ports certainly due to a bad micro-operation scheduling.

Here is the assembly of the loop with -Os:
