Debug output showsstrange characters and some requests don't seem to return. #155

Closed halloleo closed 2 years ago

halloleo commented 2 years ago

I'm using now 0.8.2 and simple request with the curl cli work fine, but I plugged the proxy into PyCharm to get plugins listed and installed from the Jetbrains servers, but this is very flaky: Listing plugins somewhat works, but installing them never returns. (On another machine with direct internet access I don't have these problems.)

The debug output has strange characters in it:

Some additional info:

px-proxy and PyCharm run on the same Linux machine (RHEL 7.9). px-proxy is in its own virtual env. PyCharm renders via X to another machine.

How can I provide more details for this?

I'll look into the code, meanwhile, can you try upgrading curl > v7.45 to see if it helps? You can get Px to use a different curl by setting LD_LIBRARY_PATH.

Hi @genotrance

Thanks for looking into this!

  1. I have upgraded to 0.8.2 and now the PyCharm store works with px-proxy! :) Thanks heaps!

  2. Re trying it with libcurl > v7.45: I cannot uninstall the old system version of libcurl (obviously, the whole system relies on it). So, how can I just download a newer libcurl? I tried the download configurator on curl.se (https://curl.se/dlwiz/), but didn't get anywhere...)

genotrance commented 2 years ago

No worries on retrying - if it works now then we can leave as is. A newer curl will be faster since SSL connections can be reused but doubt it will be a perceptible improvement.
