BUG: Using git difftool when there is a deleted jar opens an odd session

[DEinspanjer]

I am using the suggested .gitconf from the sticky thread.

Here is the output of git status:
# On branch lagunitas
# Changes not staged for commit:
# (use "git add/rm <file>..." to update what will be committed)
# (use "git checkout -- <file>..." to discard changes in working directory)
#
# modified: .classpath
# deleted: lib/mondrian.xsd
# deleted: lib/xml-apis.jar
# modified: src/main/mondrian/server/MondrianServerRegistry.java
# modified: testsrc/main/mondrian/test/BasicQueryTest.java
#
# Untracked files:
# (use "git add <file>..." to include in what will be committed)
#
# demo/FoodMartCreateData.sql
# demo/access/
no changes added to commit (use "git add" and/or "git commit -a")


The first session opens fine. comparing .classpath to upstream.
The second compares the upstream mondrian.xsd to /dev/null which isn't ideal but doesn't cause problems for me.

The third session is weird though. It opens up two tabs.
The first tab is a folder compare session comparing a tmp folder named T (full path changes, but one example is: /private/var/folders/nk/cbb5z71s19n0jdkbhwsztfzhp9jdcq/T ) to /dev
The second tab is a file compare for MondrianServerRegistry.java.

After I close both those tabs, it starts the fourth session which is a file compare of BasicQueryTest.java.

So it seems that bcomp isn't handling the arguments being passed in for the deleted jar well. I added an echo command to the .gitconf to see what the arguments being passed to bcomp look like. Here they are:

/usr/local/bin/bcomp /var/folders/nk/cbb5z71s19n0jdkbhwsztfzhp9jdcq/T//SLot86_.classpath .classpath
/usr/local/bin/bcomp /var/folders/nk/cbb5z71s19n0jdkbhwsztfzhp9jdcq/T//Qgddom_mondrian.xsd /dev/null
/usr/local/bin/bcomp /var/folders/nk/cbb5z71s19n0jdkbhwsztfzhp9jdcq/T//pmiS75_xml-apis.jar /dev/null
/usr/local/bin/bcomp /var/folders/nk/cbb5z71s19n0jdkbhwsztfzhp9jdcq/T//B9FIRR_MondrianServerRegistry.java src/main/mondrian/server/MondrianServerRegistry.java
/usr/local/bin/bcomp /var/folders/nk/cbb5z71s19n0jdkbhwsztfzhp9jdcq/T//usOdsN_BasicQueryTest.java testsrc/main/mondrian/test/BasicQueryTest.java

Thanks for these details. This is likely related to the use of /devnull. We'll look into getting a fix in the next release.
