VGIT seems to be unable to create directories with dir in the name

Using VGIT on x86, attempting to clone a repository with a directory with ".dir" in the filename causes a file not found error when the files are being created from the git objects. As per the release notes, and installation procedure all work is being done on an ODS-5 volume.
I've "SET PROC/PARSE=EXTENDED" with no change.
A repository that triggers this issue that could be checked out is busybox (
https://git.busybox.net/busybox/ ) and the directory that causes the failure is visible on this page (hdc.dir).
https://git.busybox.net/busybox/tree/qe ... ch_testing
The result of the attempted clone looks like this.
Code: Select all
Bad news:
could not open 'busybox/qemu_multiarch_testing/hdc.dir/build' for writing: no such file or directory [2]

not surprising this causes a problem as filenames ending .DIR are reserved for directories.
presumably this directory would be called hdc.dir.dir so this could be a bug is the extended file parsing where it is not just checking for .dir at the end of the filename,
I checked and on an ODS5 disk with extended parsing enabled then a directory DIR can't be created.

some questions:
what is the contents after failure of [.busybox.qemu_multiarch_testing]
in particular does it contain the file hdc^.dir.DIR
if the file is not present can you create it before extracting from the repository?

Yes, the "File type" .DIR is reserved for directories. The "Filename" can have an ending of ".dir" or ".DIR". In DCL the "." needs to be escaped with "^". On an ODS5 disk:
Code: Select all
$ set proc/parse=ext
$ cre/dir [.x.a^.dir]
$ cre/dir [.x.b^.DIR]
$ dir [.x]
Directory WORK20:[USER.x]
a^.dir.DIR;1 b^.DIR.DIR;1
Total of 2 files.
$
That VGIT can't create such a directory looks like a bug in VGIT.

directory dir can't be created either
$ cre/dir dir
%CREATE-E-DIRNOTCRE, DIR directory file not created
-LIB-F-INVFILSPE, invalid file specification

As they said in elementary school, "Show your work." None of that is
a useful problem description. "checked"? "can't"? As usual, showing
actual actions (commands) with their actual results (behavior, error
messages, ...) can be more helpful than vague descriptions or
interpretations.

Says who? "used for" and "reserved for" are spelled differently for
a reason.
its $ pipe show proc /parse > FRED.DIR
its $ type FRED.DIR

For a good time, compare a DIRE /FULL report for an actual directory
file with one for any old file named "*.DIR;1". Hint: Look for
"Directory file".

Or, perhaps, in the CRTL? As usual, many things are possible.

The directory is empty as this is where the file creation process stops.
Pre-creating the tree results in vgit claiming the [busybox] directory isn't empty, which imho is good to have clobber protection.

This issue still persists after applying X86VMS-VGIT-V0104-1B-1.
I'd like to make a correction, of it being unable to create a directory ending in '.dir'
