Re: Search all revisions for a string

I don't know about the implementation similarity to the blame feature,
but I can certainly see some value in the feature itself.

Being able to search for matches of string (or a regular expression)
within a URL (possibly recursively) backwards through a range of
revisions (possibly with a stop on first match applicable per
individual file) could be useful mining tool for lost content.

This feature is definitely best implemented on the server rather than
pulling revisions to check them all. If we treat Subversion as more
than managing code then there are certainly cases where finding the
location and point in time a given phrase is added or removed
(negative match?) could be useful (probably a few source management
uses too).

As to the implementation, I don't know enough about Subversions
implementation to comment.

If the command were somthing like

svn search [-negative-match] [-stop-on-success] [-recursive] [-rev
RANGE] -regex URL STRING/PATTERN

Where

  svn search -negative-match -stop-on-success svn://..../Eg.java "void
myOldMethod"

Would list the revision number and log of the most recent version not
to contain the specified string.

Does this sound like what people have been suggesting?
