Re: [PATCH] daemon: send stderr of service programs to the syslog

 I don't know whether service programs like upload-archive or upload-pack
 write progress report to stderr or not, for example, if a client does not
 support side-bands. In this case this patch is probably not enough since
 this would fill the log with unneeded progress information. Any hints
 are appreciated.

The progress indicator can be helped . But there is now another anoyance: If 
the client terminates the connection early, this is now logged as:

fatal: unable to run 'git-upload-pack'

The reason for this is that upload-pack is run as 'git upload-pack', which 
itself spawns the external 'git-upload-pack'. The latter dies from a SIGPIPE, 
and the former, in execv_dashed_external(), dutyfully writes this down.

The easiest solution is perhaps to make upload-pack a builtin.

BUT... The motivation, of which this patch is actually a fall-out, is to clean 
up the messy error behavor of the start,finish,run_command family. To take 
care of this error message is just one more (hopefully small) point on my 
agenda.

 I intend to follow-up this patch with another one that integrates
 run_service_command() in execute() in order to streamline how the
 'incoming' fd is inherited to the service programs.

I'm not sure anymore whether the change I planned here is worth it. When I 
wrote this announcement, I had mis-remembered how daemon.c's handle() and 
execute() functions and --inetd mode interact.
