the obliterate discussion - why dumpfiltering is no valid workaround

hi there,

yep i know there has been a lot of talk about the obliterate (completely
remove, purge, erease, zap...).
and yes i know there is a workaround called dump-filter-load.
the only problem is that the workaround just does not work!
nope it doesn't.
it specifically does not work when you have inexperienced users who are so
excited about revision control that they add everything from 100MB mdb (yes,
thats MSAccess :-\) to gigs of log, to complete eclipse installers, you name
it (i'm still waiting for the first added pagefile.sys though). of course
they first add it in the wrong place anyway and then move it from place to
place.
i'm talking hundreds of files, hundreds of nodepaths, gigs of disc space.

everybody who tried to dumpfilter it knows that it can be hours of
error-prone work cating greping sed-awking dumpfiltering loading in several
iterations just to try to get rid of all files.

it's been talked for years now and i do not understand the "if it's so
important then somebody would have done it" thing.

i read tons of posts and i still don't see what is the problem with
implementing the simple case of completely erase a file/directory from all
revisions. i know some people want more functionality. but i say 90% just
want the simple case the hardcore blaster solution (call it "archive
unneeded projects and remove trash to save disc space").

i never had a look at the code (wouldn't help either, i'm a java guy) i had
some glimps into the revision files in FSFS and certainly saw loads of
dumpfiles. and i can not imagine that implementing this simple case is realy
difficult. am i wrong?

if i had just one wish it'd be a non-blocking (or very shortly blocking ;-))
svadmin obliterate MYREPOS *.log

at least would it be possible to have some "dump grep sed-awk dumpfilter
load" thing which does the work (my solution involves and cygwin-grepping
and ultraedit, not the worlds most elegant solution...)

best regards for any help with this
patrick
