gdb does not autocomplete with shell commands

Question

After recently updating gdb from GNU gdb (GDB) Red Hat Enterprise Linux 8.2-20.el8 to GNU gdb (GDB) 16.3, gdb is not performing autocomplete specifically when running a shell command.

e.g.

(gdb) !ls
thisfile.txt
(gdb) !ls this<tab>

tab is not autocompleting the file. This fails for any shell command, but works fine for any gdb command. This used to work on version 8.2. Does anyone have any ideas on how I can bring back autocompletion for shell commands in gdb? The actual shell commands work fine, but I have to manually type out the file.

Edit: I found out that autocomplete works when I don't include any shell commands. E.G. from the example above: (gdb) !this<tab> autocompletes to (gdb) !thisfile.txt. But once I pass in a shell command, autocomplete is disabled.

Have you tried reading the source code changes between the two versions? That ought to provide a clue. — Jesper Juhl

I haven't tried that, but I think that would be something like finding a needle in a haystack, especially because the two versions are vastly far apart. I'm hoping for a simpler solution. — John Demetros

Looks like it's still working with gdb-15.2, so seems like a recent regression. You might want to create a bug report for this. — ssbssa
