rsync - Feb 2011 - DO NOT REPLY [Bug 7951] New: Option for case insensitivity in filter rules

https://bugzilla.samba.org/show_bug.cgi?id=7951

           Summary: Option for case insensitivity in filter rules
           Product: rsync
           Version: 3.0.6
          Platform: All
               URL: http://lists.samba.org/archive/rsync/2007-
                    March/017381.html
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P3
         Component: core
        AssignedTo: wayned at samba.org
        ReportedBy: p.org at gmx.at
         QAContact: rsync-qa at samba.org


DESIRED BEHAVIOR:

- Filter Rule: **.gif
- Plus an argument switch like: --filter-rules-case-insensitive
Result: matches all possible case permutations of .gif

CURRENT WORKAROUND:

- Filter Rule: **.[gG][iI][fF]
Remark: Not very user friendly, especially if you have a lot of filters.

PROCEDURES:

No related bug in the tracker, I searched for all relevant
keywords/permutations.
But the mailinglist mentions request + a patch:
http://lists.samba.org/archive/rsync/2007-March/017381.html

When will this feature be implemented into the main product line?

The --ignore-case option of the "ignore-case.diff" maintained patch
applies to
filters.  Is that what you want, or do you want case-insensitive filters on a
case-sensitive run?  If you tried the option and it did not work correctly,
please provide steps to reproduce.

------- Comment #2 from chris at onthe.net.au  2011-02-11 00:23 CST -------
Rather than a command line switch which turns all filename comparisons
case-insensitive (per --ignore-case from ignore-case.diff), or makes filter
rules case-insensitive (per requested --filter-rules-case-insensitive), I'd
prefer filter rules themselves come in case-sensitive and case-insensitive
versions, e.g.:

# Exclude .gif files, but not .GIF
exclude, *.gif
- *.gif

# Exclude .gif and .GIF (and .GiF etc) files
excludei, *.gif
-i *.gif

A use-case for this is on a case-sensitive filesystem where you do care about
case sensitivity in file names (i.e. --ignore-case
isn't appropriate), but you want to filter all case permutations in some
cases
but not others (i.e. --filter-rules-case-insensitive would be inappropriate).

It would be fine if case-sensitivity could be both set by a switch in a filter
file line (for fine granularity control as suggested by Chris Dunlop) and as a
command line switch, which applies to all filter rules (catch all as mentioned
by Matt McCutchen).

I'd just like to say that I'd also prefer the implementation proposed by
Chris
Dunlop; an i flag on filter rules would be a lot more flexible.

I recently encountered the problem with this when trying to add a rule for
deleting temporary folders (*/tmp/, */temp/ etc.) and using classes is a really
horrible workaround.
