Will svnserve in daemon mode spawn child processes?

[Ed Hillmann <ed...@gmail.com>]

Hi all.  I don't know if this is wrong or not, but this is the first
I've seen of it.

I'm using SVN 1.4.3 on a Solaris 9 machine (have been using SVN on
this box for some time now), and I use svnserve to handle requests for
our local development team.  We've always started the svnserve process
manually in daemon mode.

I checked to see if it was running this morning, and I found that
there were two processes (where normally there was always one).  So, I
looked at all the ctsvn's processes (where ctsvn is the account which
owns the repositories)

   ctsvn 13863 19688  0 09:03:57 ?        0:00 svnserve -d -r
/ct/ctsvn/repositories
   ctsvn 19688     1  0   Jan 30 ?        0:09 svnserve -d -r
/ct/ctsvn/repositories

Thanks Karl.  I'll leave it alone then, and not worry about it.  In
fact, now that I look again, it's back down to the one daemon process.
 I can go back to letting SVN do its thing (which it has been doing
for us quite nicely :) ).

Thanks again for the insight.  I wouldn't have know where to look in the code.

        With a quick check of some of svnserve's source code, it appears 
that it can handle all three options:  Forking off a process for each 
connection, spinning off a thread for each connection, or remaining 
single-threaded and handling connections on at a time.
