zsh crashes with file completion
Environment
apple darwin21.0 /bin/zsh -zsh zsh-5.8.1-0-g1a490c7
/Users/okuramasafumi/.local/share/zinit/zinit.git/zinit.zsh:1643
/Users/okuramasafumi/.local/share/zinit/zinit.git/zinit.zsh:1281
/Users/okuramasafumi/.local/share/zinit/zinit.git/zinit.zsh:2759
/Users/okuramasafumi/.zshrc:52
- Operating system: macOS 12.4
- Terminal emulator: Build 3.5.0beta5
Steps to reproduce
I found it only happens in certain directory.
git clone https://github.com/okuramasafumi/xa
cd xa
nvim gemm<TAB>
Typing tab after gemm causes zsh crash. I suspect it's because the repository contains Gemfile but other repositories with Gemfile doesn't cause crashes.
I think you may come across the same bug as I have (do not have any workaround or anything, sorry), could you please check your dmesg output?
I got following message:
[ 3252.749812] zsh[25844]: segfault at 1000000a2 ip 00007f7429f8e926 sp 00007ffe0613daa0 error 4 in complist.so[7f7429f8b000+a000] [ 3252.749820] Code: 83 7c 24 08 01 0f 84 ac 0e 00 00 48 8b 05 92 95 00 00 c7 00 01 00 00 00 31 ff ff 15 7c 95 00 00 49 8b 47 08 83 c9 ff 48 8b 00 <8b> 80 94 00 00 00 c7 44 24 30 01 00 00 00 c7 05 06 99 00 00 ff ff
When I do
pacman -S libmesa<TAB>
[1] 28688 segmentation fault (core dumped) zsh
With only zsh-autocomplete enabled.
I think somehow need to file a report to zsh also as it is segv in complete.so of zsh itself.
In my case the candidate from zsh-autocomplete have only
packages
libmesode libmesode-doc
only triggering the segv when press <TAB> before the candidates are printed by zsh-autocomplete.
I got the error report from console.app, here's the content.

I think it is the same, with zsh-autocomplete: if you press the TAB before the select menu got printed out, and the actual select menu turned out to be empty, this may trigger a crash. There is comment in the scripts/.autocomplete.async:372
# Refresh if and only if our widget got called. Otherwise, Zsh will crash (eventually).
builtin zle -R
Maybe related to the crash.

@okuramasafumi @EdwarDu
Can you please try the following?
- On the command line, run
functions -t $_autocomplete__log_functions[@] - Start your steps to reproduce the problem, but stop just before the final keystroke that induces the crash.
- In another shell session, run
rm -rf $_autocomplete__log $_autocomplete__log_async $_autocomplete__log_pty - In your previous shell session, now press the final keystroke that makes
zshcrash. - Attach in a comment here the files referenced by
$_autocomplete__log,$_autocomplete__log_asyncand$_autocomplete__log_pty
Then also try the following:
- Add
zstyle ':autocomplete:' async noto your.zshrcfile. - Start a new
zsh. - Try to reproduce the crash.
- Does it still occur?
Only $_autocomplete__log_pty has content, the other two are empty: more $_autocomplete__log_pty I zshexit: write error: Input/output error zshexit: write error: Input/output error zshexit: write error: Input/output error zshexit: write error: Input/output error zshexit: write error: Input/output error zshexit: write error: Input/output error zshexit: write error: Input/output error zshexit: write error: Input/output error zshexit: write error: Input/output error zshexit: write error: Input/output error zshexit: write error: Input/output error zshexit: write error: Input/output error zshexit: write error: Input/output error zshexit: write error: Input/output error zshexit: write error: Input/output error zshexit: write error: Input/output error zshexit: write error: Input/output error zshexit: write error: Input/output error
-- with zstyle ':autocomplete:' async no still crashing.
with this commented out, seems to be okay now.
#zstyle ':autocomplete:*' insert-unambiguous yes
@marlonrichert commented out line 168, 169 in .autocomplete.async, with zstyle ':autocomplete:*' insert-unambiguous yes
seems to be okay.
Anything to help please do let me know.
@EdwarDu Thanks! Now at least know at which point the crash occurs. However, I'm still not able to reproduce this.
@EdwarDu @okuramasafumi Can both of you please try to run your test case in the following setup? Does the crash then still occur?
cd $(mktemp -d)
> .zshrc <<EOF
PS1='%# ' PS2= RPS2='%^'; setopt transientrprompt interactivecomments
source /path/to/zsh-autocomplete.plugin.zsh
EOF
env -i HOME=$PWD PATH=$PATH TERM=$TERM ${TERMINFO:+TERMINFO=$TERMINFO} zsh -d

If I add
zstyle ':autocomplete:*' widget-style menu-select
zstyle ':autocomplete:*' insert-unambiguous yes
to the profile above, I can reproduce the crash
@marlonrichert I cannot reproduce with this setup. I also set
zstyle ':autocomplete:*' widget-style menu-select
zstyle ':autocomplete:*' insert-unambiguous yes
so that might be related as @EdwarDu pointed.
I'm unable to reproduce this:
% cd $(mktemp -d)
% > .zshrc <<EOF
PS1='%# ' PS2= RPS2='%^'; setopt transientrprompt interactivecomments
zstyle ':autocomplete:*' widget-style menu-select

Been getting a lot of segfaults too lately. I am ssh-ing to the server running zsh-autocomplete and it kills my connection. Syslog has this line - kernel: [355798.498214] zsh[35107]: segfault at 55f6f05de2a0 ip 00007f5e130b9d3c sp 00007fff822674f0 error 4 in complist.so[7f5e130b7000+b000]
@YenLegion If you could make me a minimal, reproducible test case, that would help a lot. I cannot fix the problem if I cannot reproduce it.
I think somehow need to file a report to zsh also as it is segv in complete.so of zsh itself.
@EdwarDu That is correct, but they won’t be able to do anything about it until we figure what code is actually causing it to crash. If you can find out what it is, that would be super helpful to both me and the Zsh team.
Can you git pull and try again? Does the bug still occur with the latest version?
I have been using custom build zsh-5.8.1 + git version of this plugin for some time now, have not come across the same issue recently.
OK, I’m gonna close it, then. If someone still experiences this, let me know.
I got a bit time recently to hunt this, and I'm able to reproduce it constantly with my work environment (cd to a slow nfs directory with an invalid subdirectory will crash most times, e.g. cd <slow_nfs_path_dir>/dirab where dirab does not exist, just press tab fast enough before the menu shows up, segfault will happen). I tried to build zsh with debug symbols and try to catch in gdb to see what part is causing this problem. Though I don't know the root-cause yet, I found that in zsh/Zle itself there is do_ambiguous function handle the matching and insertion, then there are two lines in .autocomplete.async
[[ $_lastcomp[insert] == *unambiguous ]] && builtin zle .auto-suffix-retain # Make the cursor stay in the right place.
seems to in conflict of Zle's internal management.
If I comment out these two lines, then I can't reproduce the segfault doing the same thing above.
@marlonrichert : Are those two lines actually necessary? What is behavior without/with thse two lines? (I can't observe behavior change without them)
Comment out thse two lines may not be the correct solution (may just lower the rate of segment that my tab pressing is not faster enough to reproduce).
I agree that it is partially a design flaw at Zle's side, it should not crash on segfault even client side has wrong settings etc.
Thanks for investigating! Do you think you could make a small, reproducible test case for this without using Autocomplete and submit it as a bug report to the official zsh-workers mailing list? That would help a lot.

Without these, the cursor sometimes jumps to an unexpected position when using insert-unambiguous. Since this happens during autocompletion, it can be quite confusing.

sorr y for the late reply. I will try, but I'm not familiar with the widget scripting part, and I can't reproduce reliably on my own desktop.
@EdwarDu Give it a try and if you run into problems or have questions, I’ll be happy to help. 🙂
