So we're splitting up the headers (which I don't love, but will hold my tongue for the most part).
Jun 11 2021
We're going to want some documentation about this option. Please add it here: https://libcxx.llvm.org/UsingLibcxx.html#id7
(The files that generate this are under libcxx/docs).

Assuming this still merges, I don't have any issue with it.

Removing the std::iterator inheritance is potentially ABI breaking. In particular in the case of reverse_iterator.
If the iterator provided to reverse_iterator also inherits from std::iterator, then the first member of reverse_iterator goes from having an offset of 4 to an offset of 0 bytes
(because the compiler couldn't place the same empty base at the same address).

I'm working to see if I can fix forward the template depth and constexpr
issues, but I would appreciate some help from @ldionne as the original
In general this removes a bunch of carefully constructed SFINAE meant to improve compile times.
I'll look into getting that back.

Has this been tested with various sanitizers on? Does it give warnings about weird object lifetimes?
Apr 19 2021
I would need to see analysis of the cost of always passing an additional parameter to these iterators constructors before I approve this.
Apr 7 2021
There's another bug with SFINAE depth increases that's blowing up at Google.
I suspect we can get that back.

I like this patch. It's targeted and fixes the problem it's aiming at well.
Here is one regression I've found so far:
Apr 1 2021
I'm a bit worried about some of the tests that were deleted. Not the ones for extensions, but some of the ones added to prevent regressions with SFINAE.

Can we please change the .compile.cpp to just .pass.cpp. There's very little to no cost to actually run the test, and doing so seems safer to me.
It avoids allowing runtime tests to be mistakenly added to these files without anybody noticing.
LGTM after addressing the current inline comments.
Please make sure the other reviewers don't have any unresolved comments before submitting.

Due to some complexities libc++ has dealing with the allocator, as well some optimizations it would be a serious undertaking to restructure libc++ to properly construct the types in the hash containers,
This change would be greatly simpler and much appreciated.
LGTM. Nice tests, and thank you for moving the test header into support.
LGTM. I like Arthurs suggestion about the tests. But otherwise this change seems ready to go.
LGTM. I don't want to squash the conversation here, but I think we've discussed it enough. The actual changes here look solid, and I think they should be allowed to proceed.

LGTM assuming the inline comments get addressed.

I don't see any major issues with patch. It looks OK to me.

We definitely want to unqualify __unwrap_iter to unbreak chromium. That's somewhat intended to be a customization point (until the proper contiguous iterator stuff lands).

I don't see a reason to keep the builders.

Bots are clean now.
Attempting to trigger rebuild
I'm trying to trigger a rebuild. Does accepting as libc++ do it?
Revert the addition of unneeded availability XFAIL's to variant tests.

After talking to @ldionne, the negative compilation tests aren't inappropriate here. I'm happy to see the stay.
I'm personally fine taking small bits of a paper.
I would rather it than have a full implementation get stuck in review.

LGTM as well. Thanks for working on this!

IDK if I know what's causing the issue, but this change LGTM.

How do we implement the "Mandates" requirement specified here?
Jun 4 2020
std::any, like other type erased types, cannot follow the allocator model and therefore does not use allocators.
All of that being said, this code is correct and LGTM**.
May 29 2020
Why is this code an improvement?
@mvels Do we have macro-benchmark results for this change?
May 13 2020
I'm a bit confused by the build size numbers you gave compared to the patch.
We could lift the two macros that depend on _NEWLIB_VERSION into the headers that use them.
Then we'll avoid the include in config.

I can't find any usages of this internally.

If we don't want the static env, we should remove it entirely.
Meaning, we should convert each of these tests to use dynamic_test_env and setup the required files like the remainder of the tests do.
While I support this change, it should really be accompanied by a library working group issue or paper.
May 5 2020
Unless I'm mistaken, this change is racy. Tests in different files are run in parallel.
One test could be tearing down the static environment while another in trying to construct it.
When I initially wrote the filesystem tests, I had divided them between "static" and "dynamic"; that is, tests which modified the target filesystem and those which did not.
There are some simplifications suggested in the inline comments.
Once those are addressed, this LGTM.

The entire point of the static test environment is that it's /static/.
Meaning it's checked in and not created on the fly.
This needs a bunch of additional tests. Specifically of the passing kind :-)

I assume this is a behavioral change? Why are there no new tests?

I have some concerns with how we harden our concepts,
but these can be addressed in follow up commits.

I like tests.
Assuming all of them pass;: LGTM.

I don't necessarily agree.
