What do I need to use CTM?

|

Before you can start using CTM deltas, you will need to get a special
|
||||
"base" delta that provides a starting point for all deltas produced
|
||||
subsequently to it. You can recognize these in two ways: One is that
|
||||
they are large! 25 to 30 Megabytes of gzip'ed data being common for a
|
||||
base delta. Second, they also have an 'A' appended to the number
|
||||
(src-cur.0341A.gz for instance). Once you've picked a base delta to
|
||||
start from, you will also need all deltas with higher numbers

following it.

|
||||
|

You can recognize a base delta by the 'A' appended to the number
|
||||
(src-cur.0341A.gz for instance). As a rule a base delta is produced
|
||||
every 100 deltas, the next one will be src-cur.0400A.gz.

By the way, they are large! 25 to 30 Megabytes of gzip'ed data is

common for a base delta.

If you do have the 2.0-RELEASE srcdist, you can instead retreive the

src-cur.0372R20.gz file, it's only 4Mb and it will take you to current

||||
from the 2.0-RELEASE sources.

Once you've picked a base delta to start from, you will also need all

|

Tons of them:
|
||||
|
||||
- Make local modifications to the tree possible. One way to do it
|
||||
could be this:
|
||||
When CTM wants to edit the file "foo/bar.c", it would first check
|
||||
for the existense of "foo/bar.c#ctm" If this file exists, the
|
||||
delta is applied to it instead. This way the foo/bar.c file can
|
||||
be edited to suit local needs.
|
||||
- Make a "restore file(s)" option to ctm, something like:
|
||||
ctm -r src/sys/i386/wd.c /here/are/my/deltas/src-cur.*
|
||||
would restore wd.c to the current status from the files.
|
||||
- Clean up the options to ctm, they became confusing and
|
||||
counter intuitive.
