I'm trying to send a post message to a server from an extension using

http_client

, somehow like this:

osquery::http::Client client;
client.setOptions(getOptions()); /* Local function to fill options */
<http://client.post|client.post>(request, params); /* crashes on Windows */

Works fine on Ubuntu, but it crashes on Windows. https://github.com/osquery/osquery/blob/a5bc1a33f2ad5eecb1a814d472c00a30c410d394/osquery/remote/http_client.cpp#L119 There's also a comment that says there is a leak, Is there any way to avoid this?

If you can build in RelWithDebInfo and then run under the debugger, a stack trace would help understanding what’s happening. Not sure otherwise. As for the leak, there’s no leak in theory now, the comment should say “we could resolve async, but there is a handle leak in Windows”. It’s not resolved async, the call is synchronous.

The extension has the symbols generated in the folder

PS C:\projects\osquery\build> ls .\external\extension_devo_wevent_logger\RelWithDebInfo\


    Directory: C:\projects\osquery\build\external\extension_devo_wevent_logger\RelWithDebInfo


Mode                LastWriteTime         Length Name

-a----        12/2/2022  10:49 AM      116379648 devo_wevent_logger.ext.pdb

But I cannot open them with

gdb

is there a way to avoid using

Microsoft Visual Studio

?

You can’t use gdb, that’s for Linux only and the dwarf format. You can use Visual Studio Code, or WinDBG

I see, thanks!
