Subject: incompat in cygwin choice of using '+' as domain and user separator.
Date: Thu, 23 Aug 2018 08:14:00 -0000 [thread overview]
Message-ID: <5B7DE56E.6060109@tlinx.org> (raw)
Ran in to this trying to use tar to store acls and xattrs:
> tar caf lawbins.tar scripts scripts- bin
tar: miner.js: Warning: Cannot acl_to_text: Invalid argument
tar: run-crons.sys: Warning: Cannot acl_to_text: Invalid argument
tar: smallprof.out: Warning: Cannot acl_to_text: Invalid argument
tar: tmon.out: Warning: Cannot acl_to_text: Invalid argument
tar: ubytes_to_utf8.new: Warning: Cannot acl_to_text: Invalid argument
examining one of these:
> find bin -name tmon.out
bin/tmon.out
> lsacl bin/tmon.out
[u::rwx,g::rwx,o:r-x,u:Unknown+User:rwx,g:Unknown+Group:rwx,g:Administrators:rwx,g:Bliss\Domain
Admins:rwx,m:rwx/] bin/tmon.out
I tried tar in an existing dir:
> mkdir test
> tar caf test.tar test
> ll test
total 0
> cd test
> tar xaf ../test.tar
> ll
total 0
drwxrwxr-x+ 1 0 Aug 22 15:26 test/
> lsacl test
[u::rwx,g::rwx,g:Bliss\lawgroup:rwx,g:Bliss\Domain
Admins:rwx,m:rwx,o:r-x/
u::rwx,g::rwx,g:Bliss\lawgroup:rwx,g:Bliss\Domain
Admins:rwx,m:rwx,o:r-x] test
With the above and only standard separator chars, no problem
I'm guessing, but '+' is a reserved char that's not permitted in
acl_to_text...
Perhaps it might be good to not set the default to some non-default, since
the default(\) seems to work most places, including on linux, though
you do have to allow '\' in the list of allowed chars in /etc/login.defs
How do I change the default separator char from '+' back to '\'?
(by default, I mean the char that is used when the corresponding ID
isn't in /etc/passwd?
Thanks!
