3678	"[MidnightCommander/mc] ""Cannot make the hardlink"" error popup is missing critical information and is not dismissable (#110)"	Petros	andrew_b	" First: thank you for your hard work keeping mc up to date :)

 Second:
 I did open an issue on github, with detailed description, that was closed by Andrew Borodin with a note that I should open it here.
  Unfortunately the issue is made unaccessible (most probably the whole issue tracking got disabled on github/mc), so I can't copypaste the content, please copy that here if you still have access or do have an email copy.

 And the report:

Ubuntu14.04
$ mc --version
GNU Midnight Commander 4.8.11
Built with GLib 2.39.1
Using the S-Lang library with terminfo database
With builtin Editor

Virtual File Systems: cpiofs, tarfs, sfs, extfs, ext2undelfs, ftpfs, sftpfs, fish
Data types: char: 8; int: 32; long: 64; void *: 64; size_t: 64; off_t: 64;


 Usecase (from memory):
 - user tries to copy/move a whole directory from /mnt/disk1 to /mnt/disk2 (different disks, different partitions)
 - process starts, ETA is like 2 hours, user leaves computer
 - the source directory contains hardlinks (maybe 5 files are the same)
 - as target is on a different filesystem making hardlinks is not possible
 - mc pops up a dialog, that it cannot make the hardlink, and hangs. 
  - bug1: The dialog has no options for the user, and it does not even contain the filenames, so the user won't know and can't do anything just dismiss the dialog
  - bug2: the dialog pops up again, with no way to disable this
  - bug3: the dialog does not tell the user what will happen (skip or copy). (Mc does a standard copy of the file, of course this is the expected result, but no information whatsoever)
 - user checks the computer 2 hours later, and finds mc hang on the first hardlink, where user has to press enter, and wait 2 hours OR risk hanging again. 

 So this is only a userinterface frustration:
 - no new information for the user
 - no questions asked
 - there is a trivial answer for the ""what to do?""
 - mc already solves the problem by copying (see later for a better way)
 - makes the user go nuts if there are 2000 hardlinks :)

 Correct solution:
 - if someone tries to copy/move files to an another partition he/she expects MC to create an exact replica. If technical issues happen and there's only one solution mc should do that to solve the problem. (create a standard file)
 - if it's a must to pop up a dialog, it should always contain the file that has the problem, and more than one option for the user to decide what to do, also for every option there should be an option to do that always (Skip, Skip All, Copy, Copy All, Abort...)
 - also it would be nice to set the default in configuration (like ""make a copy of a hardlink if it's on a different filesystem"" options:  ""always"", ""ask"", ""never"", default: ""always""), so the blocking popup would get eliminated from the workflow.

Optional feature:
 - if one user tries to copy 8 files that are hardlinks of the same file to a different filesystem, the copy should happen once, and 7 hardlinks should get created on the target filesystem, because that configuration is the closest to the original.

 But for starting, please eliminate the errorpopup, every optimisation could get implemented later.

 Thank you again,
