That will not help. git is not smart enough to deal with back-patching
changes in code that has moved from one file to another. If you force
this through it will mean manual adjustment of every back-patchable fix
that has to touch this code, for the next five or six years. Yes, the
name "common.c" is a bit of a misnomer now, but that doesn't mean we
have to change it, especially since the file's header comment already
explained what it was common for (and could be modified some more if
you don't find that adequate).

I don't think there is any "long-term code clarity" gain here that is
worth the maintenance headache. Please put the existing functions back
where they were. Inventing new files for the new code seems fine.

Well, you do a lot more backpatching than I do, so I am willing to do as you request, but looking at the git history for common.c, I don't see a lot of backpatching for this file. Basically, if we keep the existing functions in common.c, we are deciding that it is never worth moving C functions to new C files for source code clarity. I was not sure we had made that decision in the past. -- Bruce Momjian <bruce@momjian.us> http://momjian.us EnterpriseDB http://enterprisedb.com + It's impossible for everything to be true. +

I once held hope that git would let us be more flexible about this,
but experimentation has shown that it's not significantly smarter than
CVS about back-patches in moved code :-(.
I don't want to say that we should *never* move code once it's released;
but I think the bar for that needs to be set pretty high, and this
particular case isn't clearing the bar for me.

OK, hearing no other opinions, I have moved the functions back into common.c, and created a new dumpmem.c/h. Applied patch attached.
