>Release: FreeBSD 3.0-CURRENT i386
>Environment:
Anyone building from stale sources
>Description:
When someone reports a problem, there is always confusion because the date that
they BUILD a kernel is not a reliable indicator of the version of the source tree
from which they built it.
>How-To-Repeat:
Extract the sources from the CVS tree using some past date. Build a kernel.
Note that the date in the version is the current date rather than the date
of the sources. The kernel is actually much closer to matching one from
many days ago rather than one produced from today's tree.
>Fix:
Place a file in the tree that represents the date of the source tree rather than
the current date.
Until this is done, each user can approximate that date by locally building
the file at the time that he updates their source.
For Example: (Assuming that the CVSup server is up-to-date)
shrimp: {66} cat ~library/bin/do-CVSUP
#!/bin/sh
/usr/local/sbin/cvsup supfile.cvsup
TODAY=`date +%C%y%m%d`
cat >/usr/src/.timestamp <<EOF
#define FreeBSD_Source_Timestamp $TODAY
EOF
PATCH to conf/newvers.sh to utilize this file:
shrimp: {67} diff ../../conf/newvers.sh.old ../../conf/newvers.sh
41c41
< SNAPDATE=""
---
> SNAPDATE="`sed "s/#define FreeBSD_Source_Timestamp //" </usr/src/.timestamp`"
43c43
< RELEASE="${RELEASE}-${SNAPDATE}"
---
> RELEASE="${REVISION}-${SNAPDATE}"
85c85
< v=`cat version` u=${USER-root} d=`pwd` h=`hostname` t=`date`
---
> v=`cat version` u=${USER-root} d=`pwd` h=`hostname` t=`date +%D`
93c93
< \"${VERSION} #${v}: ${t}\\n ${u}@${h}:${d}\\n\";" >>vers.c
---
> \"$1 #${v}: ${t}\\n\";" >>vers.c
Please note that I intentionally use the #define construct so that it is possible
to #include the file in a "C" program. It is much easier to strip off the unneeded
portion in the shell script than it would be to attempt to generate the #define
version at compile time.
