git log - filter missing changesets

Michael S. Tsirkin· Aug 17, 2006, 08:25 UTC · lore

Hi! git log with -- parameter seems to sometimes miss changesets that affect a specific directory:

>git  log -p vofed-1.1-rc1.. -- drivers/infiniband/ulp/sdp/ | \

  grep drivers/infiniband/ulp/sdp

diff --git a/drivers/infiniband/ulp/sdp/sdp.h b/drivers/infiniband/ulp/sdp/sdp.h
--- a/drivers/infiniband/ulp/sdp/sdp.h
+++ b/drivers/infiniband/ulp/sdp/sdp.h
diff --git a/drivers/infiniband/ulp/sdp/sdp_bcopy.c
b/drivers/infiniband/ulp/sdp/sdp_bcopy.c
--- a/drivers/infiniband/ulp/sdp/sdp_bcopy.c
+++ b/drivers/infiniband/ulp/sdp/sdp_bcopy.c
diff --git a/drivers/infiniband/ulp/sdp/sdp_main.c
b/drivers/infiniband/ulp/sdp/sdp_main.c
--- a/drivers/infiniband/ulp/sdp/sdp_main.c
+++ b/drivers/infiniband/ulp/sdp/sdp_main.c


but without a filter:

>git  log -p vofed-1.1-rc1.. | \
      grep drivers/infiniband/ulp/sdp drivers/infiniband/ulp/sdp/sdp_main.c
diff --git a/drivers/infiniband/ulp/sdp/sdp.h b/drivers/infiniband/ulp/sdp/sdp.h
--- a/drivers/infiniband/ulp/sdp/sdp.h
+++ b/drivers/infiniband/ulp/sdp/sdp.h
diff --git a/drivers/infiniband/ulp/sdp/sdp_bcopy.c b/drivers/infiniband/ulp/sdp/sdp_bcopy.c
--- a/drivers/infiniband/ulp/sdp/sdp_bcopy.c
+++ b/drivers/infiniband/ulp/sdp/sdp_bcopy.c
diff --git a/drivers/infiniband/ulp/sdp/sdp_main.c b/drivers/infiniband/ulp/sdp/sdp_main.c
--- a/drivers/infiniband/ulp/sdp/sdp_main.c
+++ b/drivers/infiniband/ulp/sdp/sdp_main.c
diff --git a/drivers/infiniband/ulp/sdp/sdp.h b/drivers/infiniband/ulp/sdp/sdp.h
--- a/drivers/infiniband/ulp/sdp/sdp.h
+++ b/drivers/infiniband/ulp/sdp/sdp.h
diff --git a/drivers/infiniband/ulp/sdp/sdp_bcopy.c b/drivers/infiniband/ulp/sdp/sdp_bcopy.c
--- a/drivers/infiniband/ulp/sdp/sdp_bcopy.c
+++ b/drivers/infiniband/ulp/sdp/sdp_bcopy.c
diff --git a/drivers/infiniband/ulp/sdp/sdp_main.c b/drivers/infiniband/ulp/sdp/sdp_main.c
--- a/drivers/infiniband/ulp/sdp/sdp_main.c
+++ b/drivers/infiniband/ulp/sdp/sdp_main.c

what gives?

Most likely history simplification threw away the entire side branch.

This is getting to be a FAQ I suspect.

Yes, --full-history helps. Thanks! I'm still not sure *when* does this simplification happen - the changes that got hidden do not add/remove any files - but oh well.

BTW, --full-history does not seem to be documented on git-rev-list(1) man page.
