This test exhibits a bug in background compilation that became apparent when working on tramp support: Strange things may happen when the user changes the current buffer, because part of the code may then run with an incorrect default-directory. Introduce hooks before and after busy waiting in the cct library.
tramp support is not complete with this patch, but works if used with care. There are a few assertions that quick user interactions can trigger. Automatic background compilation via tramp is very slow, because tramp opens a new connection with all overhead for each asynchronous coqdep and coqc invocation. With this patch, tramp support only works for Emacs version 26 or later, because it uses make-nearby-temp-file. Modifications: - switch to functions that properly deal with remote or magic files - protect sentinels against multiple instances running interleaved, which suddenly happens under tramp - recognize the error when coqdep cannot access a file Fixes ProofGeneral#104 and fixes ProofGeneral#203.

FTR:
Merging now would need to warn users about not triggering any tramp feature during background compilation. |
