zsh crashing when certain alias are set and `insert-unambiguous` is on #176

Closed ChocolateOverflow closed 3 years ago

ChocolateOverflow commented 3 years ago
  1. Set zstyle ':autocomplete:tab:*' insert-unambiguous yes in .zshrc
  2. Set an alias (e.g. please=sudo) in .zshrc or during run time
  3. Have a file/directory in the current directory, whose name starts with the beginning characters of the alias from step 2 (e.g. gawr)
  4. Tab-complete with the alias from step 1 typed out
  5. Press any key -> crash

Example:

alias g=git
mkdir gawr

cd g<TAB>
# crash
alias qwe='print "Hello World"'
touch qwerty

file qwe<TAB>
# crash
alias qwerty
touch qweasd

file qw<TAB>
# crash

Note that in example 3, zsh crashes if the string before the <TAB> is the beginning sub-string of both the alias and the file name, so zsh crashes if the typed out string is q, qw, or qwe but not qwer or qwea

Having checked journalctl, I've found core dumps for zsh so I'm pretty sure zsh crashed. I'm not sure if this bug is in zsh or zsh-autocomplete but these crashes only happen when zsh-autocomplete is on.

@ChocolateOverflow Sorry, but I cannot reproduce this. Here's what I did:

> cd $(mktemp -d)
> ZDOTDIR=$PWD HOME=$PWD zsh -f
% zstyle ':autocomplete:tab:*' insert-unambiguous yes
% source /Users/marlon/git/zsh-autocomplete/zsh-autocomplete.plugin.zsh
% alias g=git; mkdir gawr
% alias qwe='print "Hello World"'; touch qwerty
% alias qwerty; touch qweasd

I then tried all the tab completions you listed and they all work fine for me. No crashes whatsoever.

Can you please try the steps above? If they work without crashes for you, too, then you must have something else in your Zsh config that's interfering.

ChocolateOverflow commented 3 years ago

I've found that it crashes when zstyle ':autocomplete:tab:*' widget-style menu-select is set, not zstyle ':autocomplete:tab:*' insert-unambiguous yes. Not sure if I copied the wrong line or something previously.

marlonrichert commented 3 years ago

@ChocolateOverflow OK, now I tried this:

> cd $(mktemp -d)
> ZDOTDIR=$PWD HOME=$PWD zsh -f
% zstyle ':autocomplete:tab:*' widget-style menu-select
% source /Users/marlon/git/zsh-autocomplete/zsh-autocomplete.plugin.zsh
% alias g=git; mkdir gawr
% alias qwe='print "Hello World"'; touch qwerty
% alias qwerty; touch qweasd

Still works fine.

Can you try the above, please, and let me know the result?

ChocolateOverflow commented 3 years ago

I did get crashes following your steps. Since it's zsh that's crashing, it might be a problem with zsh version 5.8. Also, I'm on Manjaro Linux, whose version might be the culprit.

$ zsh --version
zsh 5.8 (x86_64-pc-linux-gnu)

It seems you're on Windows. Please check and compare your version of zsh.

marlonrichert commented 3 years ago

No, I'm on macOS. But I do use Zsh 5.8.

Can you try the same steps again, but with setopt verbose xtrace just before you initiate the crash? What are the last lines that get printed before it crashes?

From your output, it appears that Zsh crashes after the Tab widget returns control to the Zsh Line Editor. Sorry, but I cannot help you with that. You should probably contact the Zsh mailing list about this: http://zsh.sourceforge.net/Arc/mlist.html

They will be better able to help you figure out what's going wrong. If it turns out that there is something I can do about it, please report back here and I will reopen this issue.
