Hi ctm-users@freebsd.org
Anyone else seeing similar strangeness ? ...
No problem running on 9.2-RELEASE, but on today's current :
	( /usr/src .svn_revision 308280 .ctm_status src-cur 12727 )
	after an installworld & kernel )

cd /usr/svn; cat .ctm_status
	svn-cur 5081
ctm -q /pub/FreeBSD/development/CTM/svn-cur/svn-cur.05[0-9][0-9][0-9].xz
	/pub/FreeBSD/development/CTM/svn-cur/svn-cur.05000.xz \
	Fatal error: Probably not a CTM-patch at all.
	# Yes I know I dont need earlier deltas, but its a cut & paste
	# suggestion from my standard script
	# The point is, ctm always used to just skip past deltas it didnt need,
	# including those it now doesnt recognise as deltas.
	# ctm also fails on delta it does need, see below:
	# Both these fail:
ctm    /pub/FreeBSD/development/CTM/svn-cur/svn-cur.05082.xz
ctm -v /pub/FreeBSD/development/CTM/svn-cur/svn-cur.05082.xz
	Fatal error: Probably not a CTM-patch at all.
	ctm: exit(65)

Delta is not corrupt:

cd /pub/FreeBSD/development/CTM/svn-cur
sha256 svn-cur.05082.xz
	SHA256 (svn-cur.05082.xz) = d2b20f44265cca77a811eb074abdbe58466bf72d8f5f3a39113a7b82a5a0b1b8

ssh ctm.berklix.org	(or as no public login, ftp & sha256 localy)
cd /pub/FreeBSD/development/CTM/svn-cur
sha256  svn-cur.05082.xz
	SHA256 (svn-cur.05082.xz) = d2b20f44265cca77a811eb074abdbe58466bf72d8f5f3a39113a7b82a5a0b1b8

Proof that its not delta at fault, but ctm command:

cd /pub/FreeBSD/development/CTM/svn-cur; pwd
	/.amd_mnt/fire/0s4/ftp/pub/FreeBSD/development/CTM/svn-cur
cd /usr/svn;pwd
	/data/usr/ftp/pri/FreeBSD/development/FreeBSD-SVN

ssh fire	# 9.2 host
cd /host/lapr/data/usr/ftp/pri/FreeBSD/development/FreeBSD-SVN
ctm /0s4/ftp/pub/FreeBSD/development/CTM/svn-cur/svn-cur.05082.xz
	ctm: .ctm_status: Permission denied
	# OK, i just auto apply deltas from /etc/aliases, hence
	# it complaining about ownerships, but not about delta content.

ssh -l mailnull-csh localhost	# still on 9.2 host
cd /host/lapr/data/usr/ftp/pri/FreeBSD/development/FreeBSD-SVN
ctm /0s4/ftp/pub/FreeBSD/development/CTM/svn-cur/svn-cur.05082.xz
	> FS .ctm_status
	> SV
	svnadmin: E000045: Can't get exclusive lock on file 'base/db/txn-current-lock': Operation not supported
	Broken pipe
	# OK that's some NFS problem applying delta, but at least old
	# 9.2 ctm command accepts delta to apply, unlike current ctm

Curiously I am not seeing same problem running on 12 current file system
& 12 current bin/ctm, applying deltas to src-cur/
cat .ctm_status
	src-cur 12727
ctm -q /pub/FreeBSD/development/CTM/src-cur/src-*.1[0-9][0-9][0-9][0-9].gz
cat .ctm_status
	src-cur 12729

Cheers,
Julian
