Hello,

Can I please get a review and a sponsor for the patch for the
enhancement noted in https://bugs.openjdk.java.net/browse/JDK-8227170?

The webrev containing the patch is here
http://cr.openjdk.java.net/~jpai/webrev/8227170/00/webrev/

For some context about this change - there's been some discussion on
this in the jdk-dev list here
https://mail.openjdk.java.net/pipermail/jdk-dev/2019-June/003076.html.

The patch in the webrev, does the following things:

- In addition to ignoring the JTwork and JTreport sub-directories, this
now also ignores these directories at the root of the repo. This patch
uses "syntax: glob" to easily ignore such directories, instead of the
(default) "regex" syntax. In the jdk-dev mailing list discussion,
Gustavo suggested to continue using the regex syntax and listing the
following in the .hgignore:

.*JTreport/.*

.*JTwork/.*

But that would then end up ignoring directories of the form
"foobarJTreport" and files under it like "foobarJTreport/blah.txt". I
guess we can still stick with a regex syntax and come up with a regex
which ignores these directories both at the root as well as
sub-directories, maybe something like:

(.*/JTreport/.*|^JTreport/.*)

(.*/JTwork/.*|^JTwork/.*)

but IMO, that appears a bit too complex when compared to the glob syntax
that's used in the webrev.

- The other change in this webrev is to ignore the
src/utils/hsdis/build/ directory which gets generated when
src/utils/hsdis is built. I included this in this patch based on
Gustavo's suggestion in that linked thread. I verified that this is
indeed the "build" location used by hsdis tool, by checking the
src/utils/hsdis/Makefile as well src/utils/hsdis/README.

Gustavo also had a suggestion that we ignore the "oprofile_data"
directory/files. But I don't have knowledge of what those files are and
didn't have a way to ascertain the right location/rule to add to the
.hgignore. So I have not included that in the current version of this
webrev. I'm however open to including this in the webrev if Gustavo and
others feel that's OK/needed.
