affects speed of doing 'cvs diff' (in all modes) and 'cvs update' over the
network.
1: don't pause at all unless running in server protocol mode.
2: if running in server protocol mode, do a kludge that intercepts the
stdout and stderr write functions and diverts them to cvs_output() and
cvs_outerr(). Yes, this might be done with fwopen() etc, but that also
requires copying "FILE" structs since you can't freopen stdout etc and
specify functions at the same time.
This HACK will go away once the cvs folks have done their changes to the
library version of gnu diff to use the callbacks as mentioned in the
comments.
things fixed in here, including the '-ko' vs. -A problem with
remote cvs which caused all files with -ko to be resent each time
(which is damn painful over a modem, I can tell you). It also found a
heap of stray empty directories that should have been pruned with the -P
flag to cvs update but were not for some reason.
It also has the fully integrated rcs and diff, so no more fork/exec
overheads for rcs,ci,patch,diff,etc. This means that it parses the control
data in the rcs files only once rather than twice or more.
If the 'cvs diff' vs. Index thing is going to be fixed for future patch
compatability, this is the place to do it.
on a checkout.
this allows us to do:
cd /usr/src/sys
cvs update -rRELENGE_2_2 -D"Yesterday"
which has been a feature sorely needed for any project with active branches.
warning: this breaks on usr.sbin/pkg_install for some reason.
everything else works as advertised.
(other things allready break on pkg_install, so it's not the fault of
this patch, it just falls faul of another bug somewhere)
If I had more time I'd make -r always accept the same syntax as -j (tag:data)
See freebsd.h and freebsd-elf.h for the silly comment that cgd@netbsd.org
wanted me to add about his claim that uncommented source files that
have been publicly available for ftp for nearly a year; that are
configuration patches to a GPL'ed program; are owned by his previous
employer who refuses to release them. Well... I did as he said. As if
that makes a difference!
At this point we've got cpp, gcc, g++ ported to FreeBSD/Alpha so all
the code that uses __FreeBSD__ is correctly pre-processed. Yay.
I'll commit the bootstrap makefile next to let others play, then on
to libc.
Change errno -> error in local structure to avoid a clash with the
thread-aware version of errno which is required for a thread-safe libc.
Have discussed this with the author and he has agreed to this change. 8-)
