child_process exec && spawn just hang

[alessioalex]

Hey,

I'm trying to get the list of the authors of a git project using 'git shortlog -sne' using child process, but it seems that both exec and spawn just hang. The command works ok in the terminal, so it's really weird. Here's my snippet:

var child_process = require('child_process'),                                                     

    exec  = child_process.exec,                                                                   

    spawn = child_process.spawn;                                                                  

                                                                                                  

var child = spawn('git', ['--git-dir=/home/alessio/www/git-project/.git', 'shortlog']);                 

child.stdout.on('data', function(data) {                                                          

  console.log('stdout: ' + data);                                                                 

});                                                                                               

child.on('close', function(code) {                                                                

  console.log('child process exited with code ' + code);                                          

});                                                                                               

child.stderr.on('data', function(data) {                                                          

  console.log('stderr: ' + data);                                                                 

});                                                                                               

                                                                                                  

exec('git --git-dir=/home/alessio/www/git-project/.git shortlog -sne', function(err, stdout, stderr) {  

  console.log(arguments);                                                                         

});

Any suggestions?

Thanks,

Alex

var repo= "/home/alessio/www/git-project/";
require('child_process').exec('cd \''+repo+'\' ; git log', console.log);

Hey Jorge,

The problem is that other commands work, event 'git shortlog' (when I add the '--help' arg or another invalid argument). My problem is with 'git --git-dir=/path/to/project/.git shortlog'. That specific command hangs when using exec or spawn :(

Thanks

Yes I know, handling of params is a bit tricky and has always been... but this works fine:

var repo= "/home/alessio/www/git-project/";
require('child_process').exec('cd \''+repo+'\' ; git shortlog -sne', console.log);

So I would just use what works :-)

Hey Jorge, I just tried that and it still hangs :( Note that for whatever git command except shortlog everything works fine. Thanks for trying to help.
