QUESTION
I am currently trying to create a pex file with an Pythonfile entrypoint.
My Folder structure looks like the following:
...ANSWER
Answered 2021-May-27 at 19:19I found an answer to my problem!
To set an entry point to a .py file on a pex file you use the -c command!
e.g. pex . -r requirements.txt -c main.py -o test.pex
The official documentation is really complicated and and clunky!
Here is a blog that in great detail describes the steps you need to take to succesfully create a pex file!

This helped me a lot and I hope this helps you as well!
QUESTION
I have a fair knowledge of BitTorrent protocol. One questions has been bugging me for a while.
Always a seeding client immediately disconnects from another seed. Got a couple of questions there.
- Is the disconnect made on the local side / remote side / both?
- Before the disconnection takes place, are peers exchanged through PEX?
I think if seeds are able to exchange peer info to other seeds through PEX, it will help improve peer discovery
...ANSWER
Answered 2021-Apr-27 at 17:46The specification does not mandate if and when seeds may disconnect other seeds, although it acknowledges the behavior and allows seeds to include recently seen seeds in its PEX list which should allow downloaders to discover more seeds. The exact timing of disconnects is largely up to implementations.
QUESTION
Background:
I have an old Seagate BlackArmor NAS 110 that I'm trying to install Debian on by following the instructions here: https://github.com/hn/seagate-blackarmor-nas.
I have a couple of USB to TTL serial adapters (one FTDI chipset and the other Prolific) that I've tried and have run into the same issue with both. I have made the connection to the serial port on the board of the NAS using a multimeter to make sure I've gotten the pinout correct.
Problem:
I'm not able to stop the autoboot process by pressing keys and any point during the boot process. The device also does not seem to respond to any keystrokes although they are echoed back.
What I've Tried So Far:
- Using USB to TTL serial adapters with two different chipsets
- Using the adapters on two different computers (MacBook Pro and a ThinkPad)
- Using different operating systems (MacOS, Windows 10, Ubuntu 20.04)
- Using different terminal programs (Screen, Minicom, Putty)
- Turned off hardware and software flow control
- Tested output of adapters by shorting RX and TX pins and seeing keystrokes echoed back
- Commands seem to be sent to device as when I type I see my commands echoed back (not sure if this is supposed to happen)
I've been at this for a few days and can't figure it out. I've also recorded my screen while experiencing the issue: https://streamable.com/xl43br. Can anyone see where I'm going wrong?
Terminal output while experiencing the problem:
...ANSWER
Answered 2021-Apr-22 at 15:51So it turns out there is a short somewhere between the RX pin and the +3.3V pin which is not allowing me to send anything to the board. Thank you to those who have commented.
QUESTION
I created m_pFileFind using CFtpFileFind class.
I tried to search all files with FindFile() by performing dynamic allocation, but 0 is returned and the search is not available.
I tried debugging by referring to Microsoft docs, but I couldn't figure out the cause.
Please give me detailed advice.
...ANSWER
Answered 2021-Mar-03 at 08:21Please check the documentation for CFtpFileFind::FindNextFile where it states:
Return ValueNonzero if there are more files; zero if the file found is the last one in the directory or if an error occurred. To get extended error information, call the Win32 function
GetLastError. If the file found is the last file in the directory, or if no matching files can be found, theGetLastErrorfunction returnsERROR_NO_MORE_FILES.

QUESTION
I'm trying to make a button that takes the coordinates from the current location, calls the city from API and returns the name of the city in the searchbar.
At the moment when the button is pressed, it first asks for GPS permission but once you enable it it stops executing the logic down.
After permission, you need to press the same button again to change the name of the city in the search engine. Is there a way when the user allows the use of his location to execute the code without having to press a second time.

If you want to allow the permission again when user deny it you could check the following code.
QUESTION
Cross-post from https://github.com/pantsbuild/pex/issues/1181 as I didn't really know where to ask this.
I'm using Nginx Unit, which has an ASGI configuration for my FastAPI application. It's working fine, but I have no clue how to use it with a PEX.
I've attached it below, but the salient point is that there is a Python plugin for Nginx Unit which is looking for a "module" and a "callable".
What this looks like now is "apigateway.main:app" similar to uvicorn or whatever other server implementation you're using. Unlike uvicorn, gunicorn, or whatever - I don't think I can package any other tool in my pex file and use PEX_SCRIPT.
Is there any suggestion on if/how I can expose a module and variable outside of the pex?
...ANSWER
Answered 2021-Jan-21 at 02:22This was answered in the Github ticket (https://github.com/pantsbuild/pex/issues/1181):
All the traditional language here is meant to segue to the recent venv pex tool feature released with Pex 2.1.22. If you build your PEX file with venv support (add --include-tools to the Pex command line) then you gain the ability to create a venv from your PEX file. Doing so is a one-time manual step on the target machine or image:
PEX_TOOLS=1 ./my.pex venv /app That will create a virtual environment containing your app and its dependencies under /app. You can point Nginx Unit there with home. I've done all this over at https://github.com/jsirois/pex-issues-1181 to prove it works.

I have a small python script (without modules) that I want to package via pex and execute. However, i could not find any option in the documentation (https://pex.readthedocs.io/en/latest/buildingpex.html) to package script without an entry point

QUESTION
I'm using a Twitter engineered build tool pants to manage many projects inside my monorepo. It outputs .pex files when I complete a build, this is a binary that packages the bare minimum dependencies I need for each project and makes them a "binary" (actually an archive that's decompressed at runtime), my issue is a utility that my code has used for a long time fails to detect some .json files(now that I'm using pants) I have stored under my environments library. all my other code seems to run fine. I'm pretty sure it has to do with my config, perhaps I'm not storing the resources properly so my code can find it, though when I use unzip my_app.pex the resources I desire are in the package and located in the proper location(dir). Here is the method my utility uses to load the json resources:

Answered 2021-Jan-04 at 18:09I figured it out: I changed the way I access the files within the library and it works perfectly before and after the build to .pex format. I used:

Install pex
You can use pex like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
