From: Troy Daniels <udalrich.schermer <at> gmail.com> To: bug-gnu-emacs <at> gnu.org Subject: 27.2; Unknown symbols in compilation-error-regexp-alist cause Date: Thu, 5 May 2022 17:24:36 -0400
[Message part 1 (text/plain, inline)]
(A description is also at https://emacs.stackexchange.com/questions/71644/limiting-compilation-error-to-symbols-that-are-not-always-loaded/71650#71650 ) Summary: I have customized compilation-error-regexp-alist to only include errors from languages that I frequently use. This starts with cargo rustc-colon rustc rustc-refs Those values do not get added to compilation-error-regexp-alist-alist until rust-mode is loaded. If I start a compilation before I have loaded a rust file (and thus loaded rust mode), compilation-parse-errors repeatedly raises errors (dozens of times in a few seconds in a typical case) and locks emacs until the compilation stops producing output. If there is a symbol that maps to nil, that symbol should be silently ignored (or a warning issued the first time a symbol fails to map). It looks like the code after (if (symbolp item) (setq item (cdr (assq item compilation-error-regexp-alist-alist)))) should be wrapped in (when ...) statement. Reproduce: $ emacs -Q (require 'compile) M-x customize-variable RET compilation-error-regexp-alist RET Add a new entry: rust Set for current session M-x compile RET Change the command from `make -k' to `yes' At this point, emacs will make a strange noise, as it signals many errors almost simultaneously. *Messages* will have many instances of error in process filter: cond: Wrong type argument: stringp, nil error in process filter: Wrong type argument: stringp, nil and the probably several error in process filter: Variable binding depth exceeds max-specpdl-size and related errors.
