Hi folks, I need help debugging why /bin/bash, /bin/zsh would hang being launched by Eclipse (v2020-09) -> TM Terminal (v10) -> (shell) on up-to-date Fedora 33.
I am using upstream build Eclipse 2020-09 and the TM Terminal plugin: 1. As root - no problem, TM Terminal can launch /bin/bash 2. As user - both /bin/bash and /bin/zsh hang, (bash at some pselect6() ) call and both do not reach the shell prompt. They are still responsive to SIGHUP. 3. As user - /bin/fish, /bin/sh, /bin/ksh, /bin/tmux(this launches /bin/bash inside) - all work. For /bin/bash specifically the hang seems to be here: 0x00007f6fcc10024b in pselect () from /lib64/libc.so.6 (gdb) bt #0 0x00007f6fcc10024b in pselect () from /lib64/libc.so.6 #1 0x000055c978de88af in rl_getc () #2 0x000055c978de7b7c in rl_read_key () #3 0x000055c978dc8c4a in readline_internal_char () #4 0x000055c978dc97cd in readline () #5 0x000055c978d31f1f in yy_readline_get () #6 0x000055c978d33a29 in shell_getc.lto_priv () #7 0x000055c978d3632a in read_token.part () #8 0x000055c978d39c52 in yyparse () #9 0x000055c978d3d00b in parse_command () #10 0x000055c978d3d14d in read_command () #11 0x000055c978d3d415 in reader_loop () #12 0x000055c978d2f689 in main () For /bin/zsh: (gdb) bt #0 0x00007f16278953f2 in read () from /lib64/libc.so.6 #1 0x00007f16199570a6 in getbyte () from /usr/lib64/zsh/5.8/zsh/zle.so #2 0x00007f16199579c1 in getkeymapcmd () from /usr/lib64/zsh/5.8/zsh/zle.so #3 0x00007f161995a4bf in getkeycmd () from /usr/lib64/zsh/5.8/zsh/zle.so #4 0x00007f161995d354 in zlecore () from /usr/lib64/zsh/5.8/zsh/zle.so #5 0x00007f161995e0bc in zleread () from /usr/lib64/zsh/5.8/zsh/zle.so #6 0x000055d18465fb78 in zleentry () #7 0x000055d18466044b in ingetc.part () #8 0x000055d184653657 in ihgetc () #9 0x000055d18466d956 in zshlex.part () #10 0x000055d184690b56 in parse_event () #11 0x000055d184659698 in loop () #12 0x000055d184661b4e in zsh_main () #13 0x000055d18460fd8b in main () Any suggestions to track down the issue would be appreciated.
