Here's a short testcase to reproduce it: #!/bin/sh cd /tmp rm -rf z b mkdir z z/a z/b echo ha >z/a/file ln -s z/b cd b cat ../a/file emacs -Q ../a/file # buffer-file-name = /tmp/a/file Why doesn't emacs behave like cat or vim? Isn't this behavior a bad default? Thanks. ^ permalink raw reply [flat|nested] 5+ messages in thread

Isn't this behavior a bad default? Okay, so expand-file-name defined in src/fileio.c is buggy: #!/bin/sh cd /tmp rm -rf z b mkdir z z/a z/b ln -s z/b cd b emacs -Q --batch --eval='(error (expand-file-name "../a"))' realpath "../a" Why such horribly convoluted logic? What could be more straightforward? https://github.com/git/git/blob/master/abspath.c#L34 ^ permalink raw reply [flat|nested] 5+ messages in thread
