GITFNS, PSUEDOHOSTS and OPENSTREAM are not all singing the same tune

[fghalasz]

Trying to a GITFNS gwc - getting a break in OPENSTREAM (see 2nd screenshot).

Same OPENSTREAM (with {WMEDLEY} pseudohost) typed into exec also fails (see 1st screenshot).

OPENSTREAM with {WMEDLEY} pseudohost replaced by it's TRUENAME - succeeds (see 1st screenshot). (Actually didn't use TRUENAME function in these screenshots - just typed true name in - but also succeeds if use TRUENAME function on {WMEDLEY}....)

Running on latest (as of 2022-09-29) maiko and medley masters. Running on Ubuntu 20.04 on top of WSL2 on Windows 11 2022H2.

Is there a difference between WMEDLEY and GMEDLEY, given that you have them both on UNIX? I always have WMEDLEY on DSK. Does the dot at the end make a difference?

Dot at the end makes no difference.

No specific reason why I used UNIX instead of DSK for WMEDLEY. But GIT-MAKE-PROJECT always sets GMEDLEY to UNIX (see second screenshot below).

If I set WMEDLEY to DSK in GIT-MAKE-PROJECT, then gwc still fails but this time it fails with:       And OPENSTREAM on GMEDLEY fails, while OPENSTREAM on WMEDLEY (set to DSK) succeeds.       So the issue appears related to {UNIX}?

What if you make SOURCES lower case ? Maybe the Unix device on the Mac is less case sensitive than elsewhere?

Case sensitivity depends on the file system; in Windows with WSL, the WSL Ubuntu is case sensitive; SunOS is case insensitive. And {DSK} treats foo and foo. as equivalent but Unix doesn't.

Is there a SUBR that will translate a DSK filename to the exact shell command variable? It would be better than the ad-hoc code we have for MEDLEYDIR and other environment variables. We also need to support Unicode file names at some point, and that will require some Maiko changes.

[nbriggs]

SunOS is case-sensitive, Linux file systems are generally case-sensitive. WSL can be adjusted, as can macOS.

Not sure what you mean by "translate a DSK filename to the exact shell command variable"

[fghalasz]

Yes, case of sources makes a difference. But the ending dot makes no difference.

    Seems like for GITFNS dealing with git directories of Lisp code, we want a HOST with the case-insensitivity of DSK but all the other properties of UNIX.

[rmkaplan]

OK, there may not be a general fix, but I think our convention is that Lisp directories are in lower-case. And I think I put in a flag in GITFNS (not PSEUDOHOSTS) to control what gets lowercased when you are going to the git repo directory. But I think I assumed that that wasn’t need for the working (usually DSK) directory. I can change that.

@rmkaplan I think the case is not handled correctly on the git repo side of GITFNS either.

If I switch WMEDLEY over to {dsk}, then instead I get a break trying to find {GMEDLEY}/SOURCES/10MBDECLS during gwc.

See the first screen shot in my comments about 6 back. It shows the break with GMEDLEY - although not much context I admit.

[fghalasz]

If you set the global variable *UPPER-CASE-FILE-NAMES* to NIL, then gwc works fine on Linux.

(See my closing note on Issue#964)

Since it appears quite a bit of code in Medley references *UPPER-CASE-FILE-NAMES*, setting it to NIL globally is a bit risky. We should probably just wrap the DIRECTORY call(s) inside GITFNS in a (LET ((*UPPER-CASE-FILE-NAMES* NIL)) --)
