This came up on the Maxima list. Consider
|(let ((file (pathname "//tmp/.////test.txt"))) (with-open-file (stream
file :direction :output :if-exists :supersede) (values file (truename
file) (pathname stream)))) |
gcl 2.6.14 returns:
|#p"/tmp/test.txt" #p"/tmp/test.txt" #p"/tmp/test.txt" |
Losing the "/./" is unfortunate, but not really incorrect on Unix.
However, with gcl 2.7.1 we get:
|Error: Fast links are on: do (si::use-fast-links nil) for debugging
Signalled by PATHNAME. Condition in PATHNAME [or a callee]:
INTERNAL-SIMPLE-PARSE-ERROR: "//tmp/.////test.txt" is not a valid
pathname on host NIL Broken at PATHNAME. Type :H for Help. 1 Return to
top level. >> |
This version basically dislikes having consecutive slashes. On unix,
this is equivalent to just one "/".
If you change the namestring to "/tmp/./test.txt", gcl 2.7.1 works and
preserves the "/./".
It would be really nice to get this fixed before 2.7.2 is released.
