Re: Re: limiting logs and diffs to specific nodes

Hi Andrew,

Thank you for your reply. At this point I'd like to migrate this
conversation to the subversion "dev" mailing list, per Garrett Rooney's

For all you seeing this for the first time, I made a suggestion on the
"users" mailing list that the svn client support excluding nodes with an
"--exclude" (or similar) command line option during diffs and logs.

For reference, here's the original thread on the "users" mailing list:

And here's the relevant issue that has been filed. It is resolved INVALID
pending mailing list acceptance, per Lieven Govaerts' decision.

Precedence? Did you mean preference? If so, I concur. I should get off my
lazy butt and write a spec, as Garrett has suggested.

This will take me some time; I need to read some source. I need to troll the
mailing lists looking to see how other features came to fruition and decide
if this is something I want to do personally. Right now my only motivation
is that it would be cool to participate in an awesome product that I use
daily at work and at home. I need to balance that with the need to spend
time with my family on nights and weekends, since that's when I'd be working
on this. But enough about me. :)

IMO, you would definitely need the --exclude-from=FILE to be useful.

Thank you for your suggestion.

And what pattern matching standard would you use? perl regex? OS

I think simple is good, so the idea would be that nodes (and their children,
if the nodes are directories) are filtered out explicitly, by name.
Suggestions welcome, of course.

And is 1.4.0's "svn diff --summarize" an adequate workaround? Get the

--summarize sounds nice! I hadn't heard of that, but I'll check it out. It
would be much simpler to create my own filter using that.

And what does it mean to filter out 'svn log --exclude .../lib'?

I'm confused... this isn't what I wrote. Please refer to my original example
and let me know if it still doesn't make sense.

I don't know how the implementation would work, but I don't think the fact
that a a single revision can contain changes to multiple directories has any
impact on this feature request.

and how is it useful?

It's useful in the same way that "grep -r --exclude" is.

Given the plethora of filtering tools (perl, sed, grep, find, ksh, etc.)
> why do we need a specific option to exclude files?


For example, consider filtering out one directory (and its children) from a
recursive, unified diff containing many directories. While entirely possible
to hand-munge after the fact, this is much easier to do by using diff's
"--exclude" and/or "--exclude-from".

I'm not saying it's a bad idea, but I do think it falls under "nice to
> have if it's free, but I wouldn't pay money for it."

Fair 'nuff!
