  • Expand longpath error info, otherwise you just get
  SystemError: longpath: The system cannot find the path specified. 
  Stacktrace:
    [1] windowserror(p::Symbol, code::UInt32; extrainfo::Nothing)
      @ Base .\error.jl:191
    [2] windowserror
      @ .\error.jl:190 [inlined]
    [3] longpath(path::String)
      @ Base.Filesystem .\path.jl:479
  • Use abspath in longpath because GetLongPathNameW doesn't seem to handle relative paths

Fixes #54799

The issue seems to be that longpath didn't like relative paths

Might be worth perusing the discussion of the original implementation of isfile_casesensitive #13542 and a subsequent patch on Windows #19291.

LGTM. The Win32 docs on GetLongPathNameW aren't clear on this point to me, but other discussions online seem to agree that its argument should be an absolute path.

Maybe other platforms need abspath too? This is on MacOS

julia> touch("newfile")
"newfile"

julia> Base.isfile_casesensitive("newfile")
true

julia> Base.isfile_casesensitive(joinpath("dummy", "..", "newfile"))
false

Looks like on MacOS the culprit may be isaccessiblefile, which is called by isfile_casesensitive before doing anything else:

julia> touch("newfile")
"newfile"

julia> Base.isaccessiblefile("newfile")
true

julia> Base.isaccessiblefile("dummy/../newfile")
false

If my relative path is valid, in that it steps in and out of a real dir, then

julia> Base.isfile_casesensitive("src/../newfile")
true

julia> Base.isfile_casesensitive("dummy/../newfile")
false

Looks like both isaccessiblefile and ccall(:getattrlist, ...) (both are used inside isfile_casesensitive) don't like the relative path with the dummy component.

Given that isfile also fails for a dummy component:

julia> isfile("dummy/../newfile")
false

it's not obvious to me that this behavior is wrong?

stevengj commented Jul 23, 2024

On Windows, does the old isfile_casesensitive succeed for relative paths involving existing directories, or is abspath needed there too?

i.e. is this PR only for dummy path components?
