Share empty Text values #493

TeofilC · 2023-01-20T00:15:50Z

This MR ensures that empty Text values are shared.
This required:

making sure that empty values are NOINLINE.
In turn inlining cannot optimise length checks for empty text, so, we add a RULE for optimising null empty and try to use null more.
Lazy Text has a separate constructor for empty values. This means we need to be careful with code shared between strict and lazy text that we don't check for emptiness twice or when we can guarantee that they're non-empty.

Resolves #492

Bodigrim · 2023-01-21T18:00:28Z

This needs a regression test: please generate empty texts by various means and check unsafe pointer equality.

Lysxia

A lot of these checks could be moved to before the main loop of their respective functions.

It would be better to add a case pack [] = empty, skipping the A.new altogether.

Thanks for the comments! I haven't had a lot of time to work on this recently, but I'll get back to it soon, and push sone commits to address your points

TeofilC · 2023-02-04T15:43:16Z

I've pushed some changes. There's still a bit to do to optimise things and update docs/etc.

I've added a mapNonEmpty function that has the side-condition that the input is non-empty. This helps the Lazy code avoid doing impossible checks. I'll also have to do something similar for caseConvert, and some others that are monotonic increasing on length. Any opinions about where these should live? I'm thinking either Data.Text.Unsafe or Data.Text.Internal.

I've added a bunch of regression tests in their own file but do let me know if you'd like me to move them somewhere else.

TeofilC · 2023-02-04T15:46:20Z

Also do you have any tips for getting stable benchmark results. I'm aware of compiling with -fproc-alignment=64 but even with that I'm getting a lot of +/-10% variations

That's some great work!

Any opinions about where these should live? I'm thinking either Data.Text.Unsafe or Data.Text.Internal.

I would say Data.Text.Internal.

I don't have an answer regarding the benchmarking issue, but yeah I also find that the results tend to be quite volatile.

@TeofilC we are heading to a release, so it's high time to wrap up once you get a spare moment.

TeofilC · 2023-02-08T09:15:44Z

Thanks for the heads up @Bodigrim . I'll try to dedicate some time today

TeofilC · 2023-02-08T21:44:37Z

I've pushed another round of changes.

I tried to put the non-empty variants into Data.Text.Internal but they required functions from other internal modules.
Instead I've created a new module, Data.Text.Internal.Transformation with some of the worker functions I needed to extract to keep generated code nice. Let me know if you'd like me to fold that into something else or rename it.

You can move the last case earlier as | len == 0 = empty to avoid that awkward condition. Also add a comment to be careful to not let ww rebox empty.

Is there any performance change according to benchmarks?

TeofilC · 2023-02-10T11:07:56Z

I'm going to revert 51dd99c.
It looks like fully applying chunk leads to slightly worse Core. The only difference is now we allocate an extra closure

TeofilC · 2023-02-10T20:15:47Z

My last comment got it wrong there was something slowing the lazy filter down but it wasnt that.

The correct thing to do is f51caa3. We need to be careful to not check for emptiness twice, but we also need to be careful not to check for emptiness inside the inner loop. With this change the core before and after this branch is basically identical.

I'm rerunning the benchmark now, but my impression is that that was the only regression, and it's now fixed. And additionally toLower/toUpper improved significantly (strange)

Bodigrim · 2023-02-10T23:21:37Z

To be honest, I'm not quite sold on this approach. It is a big amount of changes, and still the result is fairly fragile and requires a commitment to maintain the invisible invariant in every future change.

If it is really important to have only one heap object, representing an empty text, then the systematic way to achieve it is to redefine

data Text = Empty | NEText Array Int Int

together with a pattern synonym for backwards compatibility.

I suggest we do not rush with this change in the current release cycle.

@TeofilC could you elaborate a bit more on your use case? What's the reason that your application ends up with a multitude of empty texts?

TeofilC · 2023-02-10T23:55:55Z

I'm sympathetic to that. I I initially thought this would be a relatively small change but it has really grown into something quite large. And as you say this is all a bit fragile and hard to enforce.

I think having an explicit empty constructor would be quite good and that would create symmetry with the Lazy case. Though I thought GHC was much better at optimising single constructor data types, so maybe it would be quite expensive.

To be honest, I think my use case could be satisfied without this change. We have a lot of empty text because we parse a lot of data that has that. We could avoid this by improving our parsing code.

Investigating that made me think about the general case and I thought other people would benefit from the memory savings if this was optimised at the library level.

So I won't be disappointed if this doesn't work out.

In any case it sounds reasonable not to rush this

TeofilC · 2023-02-11T12:13:19Z

FWIW I think this library already had attempts at enforcing an empty text invariant to avoid leaking backing arrays. What this MR does is enforce that more strictly and improve the benefits by sharing heap objects as well.

In my mind, this is only a "best effort" invariant. It's something we try to enforce but can't guarantee. I think that makes it a bit less onerous but gets much of the benefit.

I'd also be happy to split up this MR if that helps

TeofilC · 2023-02-11T14:51:10Z

Here's the benchmark results I promised. My system is still not as quiet as I'd like.
There seems to be a regression in reverse that I'll investigate at some point if this is still something we want.

Could you please double-check? I'm running compare_benches upstream/master TeofilC/share-empty -p toLower (https://github.com/Bodigrim/tasty-bench/blob/master/compare_benches.sh).

Thanks for taking another look. I'm hoping to come back to this soon

Thanks for your patience folks. I've finally gotten around to looking at this again.

It turns out that the performance regressions of toLower etc were simply caused by differences in eta expansion with respect to HEAD. Applying the same eta-expansion to these functions fixed the regressions.

I've also rebased the branch and squashed the commits.

Let me know if you'd like anything changed on this branch.

@Bodigrim @Lysxia this should be ready for another look when you get a chance. No worries if you'd like me to rework some things or if you are no longer interested in this

Bodigrim

Lookg good, sorry that it took me so long to review.

@TeofilC could you please rebase one last time?

Try to use the same heap object to represent all empty Text values. There are already attempts to enforce something like this through the `text` smart constructor, and in various functions by special casing the empty case. This patch expands on these attempts and adds some tests to ensure that empty Text values produced by this library are represented by the same heap object. Despite these efforts, we cannot guarantee that this will be the case in all situations and users of the library shouldn't rely on this behaviour for the correctness of their code. Resolves haskell#492.

No worries about the delay at all, thanks for taking a look @Bodigrim !

It should be rebased now

Bodigrim · 2024-01-07T18:49:54Z

(I assume that @Lysxia is happy with this patch, given the earlier approval and no material changes since then)

Bodigrim · 2024-01-07T18:51:41Z

Thanks @TeofilC!

Sadly this PR broke -fpure-haskell by reintroducing an unguarded use of cbits/reverse.c. That is totally understandable given that this PR predates the introduction of -fpure-haskell! I'll PR a fix in a few minutes.
