No suggestions in VSCode

The analysis works correctly but the I don't know why the autocompletion does not work. Other functions like go to declaration does not work either.

I'm not able to reproduce this on linux. I don't know why there would be issues specific to windows for this.

I see the exact same response contents as the request contents - are you sure that's the right message body for the response? It's identical to the completion request; there should be a JSON array or null somewhere in the response.
What extensions do you have installed with php? Do you continue having issues after upgrading php, disabling opcache, etc. - https://www.php.net/downloads.php#v7.4.14 is out and 7.4.7 is 7 months out of date

What happens if you clone phan, run composer install, then run PHAN_RUN_INTEGRATION_TEST=1 vendor/bin/phpunit tests/Phan/LanguageServer/LanguageServerIntegrationTest.php (I forget how to set an environment variable in windows command lines, if that's done no tests should be skipped)

Did you disable or uninstall other php language servers such as intelliphense - those may or may not interfere (haven't tried that - it's more of an issue for hover types)

You may want to disable VS Code's built-in IntelliSense for PHP by setting php.suggest.basic to false, to avoid duplicate suggestions.

I can reproduce the unit test failure and overall slowness (and the test failure) if I run unix2dos to convert \n to \r\n in tests\Phan\LanguageServer\LanguageServerIntegrationTest.php and then run wine /mnt/DATA/software/php-7.4.14-nts-windows/php.exe vendor/phpunit/phpunit/phpunit --testdox tests/Phan/LanguageServer/LanguageServerIntegrationTest.php

• This is definitely a bug that should be fixed
• I suspect your editor is saving all files with the windows file format - if it saved files with unix newlines that might work around this issue

(Running it on tests/misc/lsp/ for other files didn't have any impact)

So it may somehow be an issue specific to completions when the character following the cursor is \r instead of \n.
(e.g. phan's check if the cursor is at the end of a line)

A simpler way to reproduce this than running unix2dos is this patch (for which tests on Linux fail quickly (< 2 seconds each), and tests on Windows surprisingly fail slowly):

This should be fixed in version 3.0.0 of the vscode extension (by default, it uses an installation of Phan bundled with that extension, not the phan version installed in the project) and in version 4.0.2 of Phan
