IDE sync popup during build makes the build fail #3694

Open NathanSweet opened 1 year ago

NathanSweet commented 1 year ago

Many times I run a build and it fails. I run it again and it succeeds. I noticed that the VS Code project sync dialog flashes briefly when this occurs. I think a sync during the build breaks the build. Build failure looks like:

framework-arduinoespressif32/cores/esp32/main.cpp:72:1: fatal error: opening dependency file .pio/build/master/FrameworkArduino/main.cpp.d: No such file or directory

For example, if I edit platformio.ini and press ctrl+B,enter to build, a second or so into the build the project syncs and the build fails. ctrl+B,enter again and the build succeeds.

I think a sync should be done before a build and syncing should be disallowed during a build.

In case it matters, I’m using:

lib_ldf_mode = off
lib_compat_mode = off

I’m editing my platformio.ini to add a dependency to lib_deps.

Possibly related: #3207

How do I forward an issue to a forum? Are you implying this is not actually an issue but is instead a question? I would disagree.

I originally posted the issue on the forum and was directed to the issue tracker. It seems we're in loop! https://community.platformio.org/t/sync-popup-during-build-makes-the-build-fail/33468

The issue can be avoided relatively easily, once the user figures out WTF is going on, but the symptoms make for quite bad UX: builds appear to fail for bizarre reasons, yet work at other times.

project syncs

What do you mean? We don't provide any synchronization. Could you disable ALL VSCode 3rd party extensions and keep only C/C++ and PlatformIO IDE? Could you reproduce this issue again?

By "sync" I mean whatever is happening when this popup is shown, a few seconds after saving platformio.ini:

Yes, it can be reproduced easily and every time. Edit platformio.ini without saving, then run a build (ctrl+alt+B). The platformio.ini gets saved and the build starts, a few seconds later the popup appears, then the build fails.

The workaround is of course: don't do that, but maybe it can be handled another way. Ideally the build could delay until any pending "sync" is complete. Maybe when a sync occurs it can check if a build is in progress, then if that build fails print a message saying the failure may be caused by the sync. Basically any way to lessen the surprise of a build failing seemingly sporadically would be beneficial.

I don't use any 3rd party extensions, only VS Code + PIO IDE. I installed VS Code specifically for PIO, so it's a fresh install.

Thanks for the explanation. I marked this issue as "known". We will think of a solution for it. When you edit platformio.ini and make changes, we remove a build cache. The issue arises in parallel when updating metadata tries to reach non-existing files.
