Found malformed header block in dumpfile stream

[Graham Leggett <mi...@sharp.fm>]

Hi all,

Following the instructions at
http://svnbook.red-bean.com/nightly/en/svn.reposadmin.maint.html#svn.reposadmin.maint.tk.svndumpfilter
I have been trying to split a single repository "fo" like this:

hoops/blah
infinity/foo

In two separate repositories "hoops" and "infinity" like this:

/blah

and

/foo

In other words, I want to strip off the leading directory in the dump file.

Using "svndumpfilter include hoops" and "svndumpfile include infinity", I
am able to split the repository in two, and can successfully load the two
dumpfiles back into new repos.

I then use sed to remove the prefix "hoops/" from the Node-path and
Node-copyfrom-path.

This new dumpfile is now corrupt. Any attempt to load the dump file
results in the following error message the first time a binary file is
included in a commit:

Found malformed header block in dumpfile stream

It seems to make no difference whether I try and remove the directory
prefix, or change the directory prefix - as soon as the directory changes,
the dumpfile is corrupt.

The docs warn that any editing must preserve the line endings. I dumped
the repo on a Solaris system, and did editing using sed on the same
system. Does sed disturb the line endings?

Is there a new way of achieving this that is not yet in the documentation?

Regards,
Graham

Aaargh... sed corrupts the original line endings (this isn't documented
anywhere unless you go into the deep technical details of how sed handles
buffers).

The solution is to use perl -p -i "s/search/replace/" -.
