It depends on which one you mean. The global ones are inserted into the
exclude list at the point they're mentioned. For instance:
rsync --include='*.tar.gz' -C from/ to
In the above command the include overrides all the default CVS exclude
rules and the excludes that were read from the $HOME/.cvsignore and
$CVSIGNORE sources because they come after the include in the list of
options. If an exclude occurs in a local .cvsignore file, then there
is no current way to override it short of turning off --cvs-exclude and
switching all the desired rules over to a different option (e.g. by
using --exclude-from=FILE). However, I'd like to see some way to make
this more flexible.
To see the complexity of the issue, consider an --exclude-from ruleset
like this:
+ */
+ *.[ch]
- *
In this ruleset the includes are there just to override the '*'. If
they also override the per-directory .cvsignore rules, those extra rules
would be completely ignored (e.g. non-CVS directories would be included
and generated .c and .h files as well).
One solution is to give the user the ability to specify an overriding
include, such as a new '&' idiom that the perdir-exclude-from.diff (in
the patches dir) implements: "& *.tar.gz". However, there may be a
better way to go.
An idea I just thought of is to allow the user to tell us where in the
hierarchy of rules the locally-read rules get put. For instance, if we
introduce a new ". FILE" idiom, the user can tell us where the
.cvsignore file goes in the order of things:
. .cvsignore
+ */
+ *.[ch]
- *
That would probably be its default position, so the above would be
redundant if -C were specified. It would then be possible to override
a local .cvsignore rule by putting it after an overriding rule:
rsync --include='*.tar.gz' --include='. .cvsignore' -C from/ to
The nice thing about this idea is that it could also implement the
--perdir-exclude-from=FILE idiom without such an unwieldy option name.
The user could just mention a different local filename in the normal
list of include/exclude values:
+ *.tar.gz
. .local_rules
- some_file
I like this idea a lot.
