Dear developers of MonetDB,
I am trying to measure the number of BAT accesses by computing per each BAT
a sum of differences between highest and lowest indexes in ALGsubselect2.
I have instrumented the BAT descriptor with an additional integer value and
added its initialization into BATcreate. I also added an increment
operation of the value into ALGsubselect2 and modified the COLcopy function
in order to carry the acquired number around.
But it all seems to be in vain, all the values remain equal to 0 when I
check them via code.
Is my approach even sensible? Where else should I look to make this work?
I use MonetDB/RDF branch, the latest available version (monetdbd 1.7,
monetdb 1.1).
Thank you in advance!
Best Regards,
Vsevolod

I have created a new stable branch for the next feature release. This
branch was created in order to stabilize the code before the feature
release.
From now on *only* bug fixes may go to this new stable branch. I
reserve the right to undo any changes that do not comply with this
rule. I also reserve the right to admit changes that are not strictly
bug fixes.
The name for the branch is Mar2018. So in each of your stable
checkout directories you can do
hg pull
hg update -rMar2018
to update to this new branch.
