[clang] Add sections to C++ DR status page #165749

Endilll · 2025-10-30T17:20:43Z

Following recent discussion on CWG reflector, cwg_index.html now contains stable name of the section for each Core issue. I thought that this would be a useful information to have on our C++ DR status page for that handful of experts who actually open it, so here we are.

This PR consists of 3 parts:

Rewrite of a small routine that parses cwg_index.html from splits and indicies to a single regular expression with named groups, adding section information.
Changes to the rest of the make_cxx_dr_status to accommodate for the first part.
Regenerated cxx_dr_status.html.

Ideally this PR would only add lines to cxx_dr_status.html, but previously we've been leaving some newlines in issue titles (which never affected how this page is rendered), which are now properly replaced with whitespaces — hence a couple of deletions in that file.

Changes

Following recent discussion on CWG reflector, cwg_index.html now contains section number and stable name of that section for each Core issue. I thought that this would be a useful information to have on our C++ DR status page for that handful of experts who actually open it, so here we are.

This PR consists of 3 parts:

Rewrite of a small routine that parses cwg_index.html from splits and indicies to a single regular expression with named groups, adding section information.
Changes to the rest of the make_cxx_dr_status to accommodate for the first part.
Regenerated cxx_dr_status.html.

Ideally this PR would only add lines to cxx_dr_status.html, but previously we've been leaving some newlines in issue titles (which never affected how this page is rendered), which are now properly replaced with whitespaces — hence a couple of deletions in that file.

New look of C++ DR status page:

zygoloid

Including this seems nice. What do you think about combining the "Section" and "Section name" columns into a single column (eg "9.3.4.7 [dcl.fct.default]")? With the current change we're giving these two columns more of the limited horizontal space here than the issue title.

Looking at this

I'm not sure that combining the columns will help enough to save horizontal space, but it will come at the expense of readability of stable names as pointed out on the CWG reflector. Maybe we should drop section numbers instead?

Works for me. Or we could force a linebreak between the number and the name. Would that significantly increase the vertical space used by the table?

Or we could force a linebreak between the number and the name. Would that significantly increase the vertical space used by the table?

As the page currently stands, it has 2778 single-line rows in my browser. If I add section name column, this number goes down dramatically, to 996. Even at this level the table height will grow by 30% if we do that.

These numbers make me think that we should try to preserve row height. I'm not sure if there's a good way to break up section names, but even at my 150% scale there's blank horizontal space which we can widen the table into to compensate for the new column. What do you think?

zygoloid · 2025-10-31T20:56:36Z

Maybe we should think about a holistic redesign of the way we present the information at some point -- a single flat table with thousands of rows is probably not the most usable interface we can provide. (Also, these status pages don't match the visual style of either our other documentation or our restructured text-generated docs. The whole clang.llvm.org website could do with some attention from someone with the right set of skills.) But for now, making the table wider seems like it could be reasonable :)

My only real hesitation is that the table is currently sized to match the tables in cxx_status.html and c_status.html, so we'd lose a little inter-page consistency, but I think that's probably fine. (Making the other tables wider risks making them less readable / scannable, so I think we should probably leave them alone.)

I don't think there are a lot of users out there to appreciate the consistency between C++ DR status page and C++ status page, so I agree that this is a minor concern.

The latest look of the table, now wider and without section numbers:

I noticed that our website's global style forces cell contents to vertically align to the top, even though on my screenshot they are centered. I prefer centered, but I guess I shouldn't fight with site-wide styles in this PR.

zygoloid

Thanks, looks nice.

Two compiler-rt asan tests keep failing on Linux CI. I'm ignoring them as unrelated.

CC @boomanaiden154
Maybe you know why compiler-rt tests are unhappy.

boomanaiden154 · 2025-11-02T18:12:44Z

They were previously flaky (I have buildbot failure emails showing those two tests failing back to April or something). Enabling the internal shell seems to have made them fail a lot more often. I've reverted that patch for now given it caused a lot of other issues.

LGTM, this is a nice improvement!
