Hi,i think i found a bug in the handling of external dependencies (via register-external-file) in compiler/cm. Currently if an external dependency gets deleted after the registering file was compiled, it is not recompiled because a missing file does not trigger a file changed or timestamp newer condition.
With the attached patch a missing file is simply treated as newer than everything. Would that be the correct behavior?
Reproduce with:
;; ----- test.rkt
#lang racket
(require (for-syntax compiler/cm-accomplice))
(begin-for-syntax
(printf "compiled\n")
(register-external-file (path->complete-path "ext-dep"))
(with-output-to-file
"ext-dep" #:exists 'replace values))
;; --- current
# raco make sample.rkt
compiled
# raco make sample.rkt # rm ext-dep # raco make sample.rkt << Missing "compiled" ;; --- patched # raco make sample.rkt
compiled
# raco make sample.rkt # rm ext-dep # raco make sample.rkt
compiled
