Chris,
I've added a set-size filter and configured the fcsu.bat file and it seems to
work pretty well.
Here's my BAT file in case you want to add it to your next build
Fcsu.bat
@echo off
call setEnv.cmd
java -cp %JARS% com.github.cwilper.fcrepo.store.util.StoreUtil %*
It calls a setEnv.cmd that looks like this:
@echo off
set LIB_HOME=..\lib
set JARS=..\conf
FOR /F %%a IN ('dir /b /aa /on %LIB_HOME%\*.jar') DO call :cpappend %%a
goto :eof
:cpappend
set JARS=%JARS%;%LIB_HOME%\%1
goto :eof
:eof
Thanks again!!

Rebuild Utility
Hi Vincent,
I've written a storage utility that may be of help here:
https://wiki.duraspace.org/display/~cwilper/A+New+Fedora+Storage+Utility
One of the filters that's included allows you to re-compute the SIZE
*and* checksum info for managed datastreams. I was actually talking with Ben
Armintor recently about this recently and have copy-pasted my message below:
One of out-of-box the filters I wrote for it, 'SetFixity' is very similar to
the need expressed by FCREPO-724. After pointing it to your storage via spring
(see config/config.properties), the following example will iterate through all
objects in your akubra-fs-based store and set the SIZE and DIGEST info for all
datastreams where they're not already set:
./fcsu modify akubra --filter=set-fixity
It can also be used with "legacy" (pre-akubra-based) low level storage.
I never defined a filter that ONLY does size, though. That would require
creating a new class similar to this:
https://github.com/cwilper/fcrepo-store/blob/master/fcrepo-store-util/src/main/java/com/github/cwilper/fcrepo/store/util/filters/ds/SetFixity.java
..then adding a new 'filter' bean file similar to this:
https://github.com/cwilper/fcrepo-store/blob/master/fcrepo-store-util/src/main/conf/filters/set-fixity.xml
...but naming it something different, like 'set-size' and omitting the
digest-oriented bits, of course.
If you're interested in going down this road and have any questions or problems
(or code to contribute!), let me know.
Thanks,
Chris
