Bash completion syntax error - upon booting (default configs)

Cape · 2010-07-23 20:28:05

Hi all!
am I the only one experiencing this problem?
Basically after boot up i get this message on tty 1 (short version due to lack of copy/paste function):

/etc/bash_completion.d/git: line 123: syntax error near unexpected token "<".

Problem is i never touched that file in my life....

this is how it looks:

svn-remote.*.url)
            svn_remote[ $((${#svn_remote[@]} + 1)) ]="$value"
            svn_url_pattern+="\\|$value"
            upstream=svn+git # default upstream is SVN if available, else git
            ;;
        esac

## !! The following is line 123
    done < <(git config -z --get-regexp '^(svn-remote\..*\.url|bash\.showupstream)$' 2>/dev/null | tr '\0\n' '\n ')
    
        # parse configuration values
    for option in ${GIT_PS1_SHOWUPSTREAM}; do
        case "$option" in
        git|svn) upstream="$option" ;;
        verbose) verbose=1 ;;
        legacy)  legacy=1  ;;
        esac
    done

By the way, what does "<" do in bash?

Cape,

I have git 1.7.1.1-1 installed and my /etc/bash_completion.d/git doesn't look at all like yours.

I don't have the message, either.

Try to reinstall git.

this is the entire expression, and it looks like proper bash:

 107         # get some config options from git-config
 108         while read key value; do
 109                 case "$key" in
 110                 bash.showupstream)
 111                         GIT_PS1_SHOWUPSTREAM="$value"
 112                         if [[ -z "${GIT_PS1_SHOWUPSTREAM}" ]]; then
 113                                 p=""
 114                                 return
 115                         fi
 116                         ;;
 117                 svn-remote.*.url)
 118                         svn_remote[ $((${#svn_remote[@]} + 1)) ]="$value"
 119                         svn_url_pattern+="\\|$value"
 120                         upstream=svn+git # default upstream is SVN if available, else git
 121                         ;;
 122                 esac
 123         done < <(git config -z --get-regexp '^(svn-remote\..*\.url|bash\.showupstream)$' 2>/dev/null | tr '\0\n' '\n ')

while read var; do ... done < <(something) just tells bash to read var from the 'something' process in the <( ).

similarly, while read var; do ... done < ./file would read from the lines of the file.

BIG EDIT sorry guys, i had copy/pasted out of vim and cut off the second half of the pipe -- it looks like we all have the same expression and mine's not erroring... weird.

mmm... I've noticed that this file belongs to "git" package. And reinstalling git solved the problem. Now that file looks like yours. But how could it happened that pacman didn't synced it properly?

Cape · 2010-07-25 17:34:55

Oppss.. it's still giving me that message... Are we sure about the correctness of that line? Can it be an upstream problem?

ngoonee · 2010-07-26 04:57:42

Same problem here. Here's the entire error message (hand-copied, may have mistakes):-

/etc/bash_completion.d/git: line 123: syntax error near unexpected token `<'
/etc/bash_completion.d/git: line 123: `     done < <(git config -z --get-regexp '^(svn-remote\..*\.url|bash\.showupstream)$' 2>/dev/null | tr '\0\n' '\n ')'

Line 123 is

done < <(git config -z --get-regexp '^(svn-remote\..*\.url|bash\.showupstream)$' 2>/dev/null | tr '\0\n' '\n ')

which is different from brisbin33's version...

Yep, I've noticed it right after git upgrade...

brisbin33 · 2010-07-26 13:56:56

edit -- removed, see my previous post

i know that done < <(process) is just as valid as done < $(process) and is much more efficient (no call to exec) so the fix listed in the bug tracker may not be ideal.

I tried to run "sh /etc/bash_completion.d/git" and the output is the same as in tty 1, while sourceing that same file with bash doesn't give any error...

tatsuno · 2010-08-04 10:25:59

I found this thread:

http://www.spinics.net/lists/git/msg136187.html

Has anybody fixed this?

citral · 2010-09-08 11:03:16

It's still broken here. It looks pretty complicated now to fix, while I thought it was merely a broken git update.

daasdingo · 2010-10-07 06:09:26

also broken on my machine; same error:

[root@daasdingo-desktop /]# sh /etc/bash_completion.d/git 
/etc/bash_completion.d/git: line 123: syntax error near unexpected token `<'
/etc/bash_completion.d/git: line 123: `    done < <(git config -z --get-regexp '^(svn-remote\..*\.url|bash\.showupstream)$' 2>/dev/null | tr '\0\n' '\n ')'

as cape already reported, the problem probably is that this is bash-specific syntax; and the script is executed in sh.

[root@daasdingo-desktop daasdingo]# bash /etc/bash_completion.d/git 
[root@daasdingo-desktop daasdingo]#

interesting link(reply to the previously posted mail):

it appears there is a bug in /etc/profile in archlinux that mis-detects
sh as bash and run bash specific script like bash_completion.

Anyway to fix this error msg so far?

Evilandi666 · 2010-11-20 12:16:57

Installed Git few days ago and after throwing this error deleted it...

Nobody can/want fix it? Its 4 months old ...

brisbin33 · 2010-11-20 15:47:10

At what point are your systems (automatically) sourcing the bash_completion files? I don't get this message at all.

I purposely source these files myself from ~/.bashrc which parses them correctly as bash. This means it doesn't error on the `< <( )` bashism.

If you really want to suppress the message, try putting #!/bin/bash at the top of bash_completion.d/git. A hack, but it should work.

Personally, I'd like to know why some "default setups" are sourcing this file and my "default setup" is not.
