Hi Marco:

I've gone back and tried my old Qgit 1.5.3 and it was
much closer in functionality to Bitkeeper.

While I'm looking at the diffs for a file if I pull down External Diff
it launches 'kcompare' but for a file with a large change it seems
to be running extremely slow. We have a file with 13,000 files in it
and I have two changes in the file, each is an addition and deletion
of about 100 lines in one contiguous block. If I click between them
it's fine but since the 100 lines is more than one page I try to
scroll thru the diff. At this point of time 'kompare' seems to be
using 95% of the CPU time and it takes about 10 seconds for it to
scroll. It scrolls fine in the qgit diff window. It;s not a problem
for small files. Know of what can me done so that 'kcompare' works
fast on large files; something like pointing it's tmp files to a
not NFS partition.


Another problem I've noticed is that sometime while running git
it seems to spend a large amount of time  switching from one
change-set to the next; seems to be due to all of the tagged
files.

It seems that while I'm in "Rev List" mode I can select the the
two versions to compare a selected file with View->External diff...

Now, if I pull down "View File" or go to the file context were
you see the change-set for a file then I can't get the CTRL + right
click to allow me to diff two revisions of the file.

While messing around in this area of trying to diff two revision
of the file from the file context I got:

MY guess is that I should install a newer version of qgit,
I'm using 1.5.3.

How difficult is it to upgrade to the Qt4. Can I just
install it to /usr/local and not interfere with Qt3?
Last I recall messing with installing ethereal from src
I needed a graphics lib and as I recall installing it in
/usr/local/ confused some build crap. It would be interesting
to try out your new qgit-2.0.

Right, but how do I do this from the file context?

Picked up both, I'll start with qgit-1.5.7.

Installing qt4 might not be so easy; looking at:

	http://packages.qa.debian.org/q/qt4-x11.html

it seems to be pretty big. The date on 1.5.7 was very
close to 2.0 so I thought they might be very close in
functionality and you maintaining the same code for
both the common Qt3 and the new Qt4 to make it easy
for users to install.

Piet
