[clangd] assertion failure in include cleaner #99617

Closed yshui closed 2 weeks ago

yshui commented 1 month ago

To reproduce:

  1. clone yshui/deai, branch clangd-bug
  2. generate compile_commands.json
  3. clangd -check=include/deai/c++/c_api.hh
yshui commented 1 month ago

My attempt at fixing #99514

yshui commented 1 month ago

Wait, I realized the version of deai currently on github doesn't have this problem. Let me fix that.

Edit: I think I just forgot to push my .clang-tidy. should be reproducible now.

Author: Yuxuan Shui (yshui)

To reproduce: 1. clone [yshui/deai](https://github.com/yshui/deai) 2. generate compile_commands.json 3. `clangd -check=include/deai/c++/c_api.hh`
HighCommander4 commented 3 weeks ago
  1. generate compile_commands.json

Could you give some more details on how you generate compile_commands.json for this project?

HighCommander4 commented 3 weeks ago

I figured it out: meson setup -Dplugins=[] build generates build/compile_commands.json.

However, I do not get a crash at step 3. Could you attach the output of clangd -check=include/deai/c++/c_api.hh please?

yshui commented 3 weeks ago

hmm, i can't reproduce it now either... i wish i had at least saved a stack trace :/

i'll try to see if i can make it happen again.

yshui commented 3 weeks ago

ah! i see.

meson setup -Dplugins=[] build

this has to have -Dbuildtype=release. yeah this bug only happens if optimization is enabled.

yshui commented 3 weeks ago

(this one doesn't have symbols)

meson setup -Dplugins=[] build

this has to have -Dbuildtype=release. yeah this bug only happens if optimization is enabled.

Thanks, I can reproduce the assertion failure with -Dbuildtype=release.

And here is the actual assertion message and more detailed stack trace from a debug build:

yshui commented 3 weeks ago

@HighCommander4 and my analysis in #99514 . basically the source location is calculated relative to one file, then later combined with a different file.

HighCommander4 commented 3 weeks ago

I've tried to reduce the code that triggers the assertion failure to something minimal, but it's proving difficult.

yshui commented 3 weeks ago

@HighCommander4 the size of the file matters. if the bug disappears sometimes you should try fill the file with garbage e.g. comments.

HighCommander4 commented 2 weeks ago

I started debugging a partially reduced testcase, and I discovered something quite interesting.

I added an assertion in CollectMainFileMacros::add(), checking that the added location was indeed in the main file. When that assertion failed, I looked at the stack trace, and found that it was the modernize-use-trailing-return-type clang-tidy checker calling into the preprocessor here.

That call can get into PPCallbacks::MacroExpands(), but unlike the calls to PPCallbacks::MacroExpands() that occur during the usual course of parsing the file, this call is not interleaved with FileChanged() calls the way the clangd implementation of PPCallbacks expects.

The clang-tidy checks are in turn run by clangd here, a bit after the actual parse which happens here.

Clangd cares about its CollectMainFileMacros callbacks running during the parse, but (I'm pretty sure) not during the clang-tidy checks. So, an idea for a solution could be to remove the CollectMainFileMacros callbacks in between the parse and the clang-tidy checks.

HighCommander4 commented 2 weeks ago

When that assertion failed, I looked at the stack trace, and found that it was the modernize-use-trailing-return-type clang-tidy checker calling into the preprocessor here.

(By the way, this means that a workaround for the crash is to disable this checker in .clang-tidy (or only for clangd using https://clangd.llvm.org/config.html#remove-1)).

HighCommander4 commented 2 weeks ago

Here is a minimal test case which triggers this new assertion:
