Implement a recursion limit #186

nrc · 2019-05-23T08:59:05Z

This PR implements a recursion limit, which can be disabled by not setting a Cargo feature (which is on by default). This change is technically not backwards compatible, but in practice very few programs should hit the recursion limit.

Although adding a context argument complicates the API somewhat, most clients would not implement or use the methods with the added argument and would instead only use decode, which is not changed.

Fixes #176

Design question: it occurs to me that this could be made simpler by passing the context by value and have enter_recursion create a new context with a decremented counter, rather than modifying the current context. Then we don't need to worry about incrementing the counter when we return (so don't need the RAII object, etc). However, if we add anything to the context in the future, we will have to use Rc<RefCell> and pay a cost of cloning, whereas the current implementation is more future-proof. So, if you think we might add more to the context in the future I would land this PR as is, but if you think that is unlikely, then I could change the implementation to the 'by value' version.

Test failures are because 1.32 does not have great support for NLL, I believe 1.33 should be ok.

That sounds like a good idea. If we need to add additional shared state to the context in the future we can do it through an inner referenced context objected. As I understand it this would also mean removing the need for unsafe, right? There's no unsafe in the decoding path currently, and if possible I'd like to maintain that.

This is part of the public API, so it shouldn't have a context param, it should be handled the same as you did decode_length_delimited above.

In other words, merge_field should be the only method with a context param.

That doesn't work unfortunately because merge is called recursively so if we don't include the context, then we lose track of the recursion count

Yeah I think this can be significantly simplified through passing an owned struct which includes the counter, e.g. fn recurse(&self) -> Result<Self, DecodeError> to pass the context, and automatically increment or decrement the counter and check against 0 or max (I don't love the name recurse, though, so maybe there's a better option for that).

To enforce that recurse is used, the type should opt-out of Clone and Copy.

To enforce that recurse is used, the type should opt-out of Clone and Copy.

hmm actually that would be problematic for decoding repeated values. Maybe a suitably named method which is effectively a clone but wouldn't be used accidentally would solve that.

I think using Clone but opting out of Copy is fine. It doesn't force you to opt-in to recursing, but I don't think you can in general because the context can always be moved. Where there is a loop, it is nice to clone rather than implicitly copy I think - there is at least a hint that in some cases there is something else to do.

The test failure is happening when using prost in edition-2015 mode. I want to keep that an option for the time being, so you may need to adjust the problematic code to not rely on NLL. You can test locally with cargo test -p tests-2015. I have a feeling this may fall out naturally from removing the stack guards anyway.

nrc · 2019-05-27T21:39:35Z

You can test locally with cargo test -p tests-2015.

This doesn't work - I think you do need an old compiler to test it (because NLL is backwards compatible, I think 2015 mode does not turn it off)

I have a feeling this may fall out naturally from removing the stack guards anyway.

Sadly not because I use it in the test code to create the deeply nested proto.

@danburkert A few questions in replies, but otherwise all points addressed. This should work on 1.33, but I'll keep an eye on the CI.

nrc · 2019-05-28T22:52:23Z

CI errors seem to be due to a missing lib or something breaking the conformance tests. Any idea what is going on here?

nrc · 2019-06-04T04:47:08Z

@danburkert ping: PR is updated, but I don't know how to fix CI. Comments above ^

Hey @nrc, I apologize for the slow turnaround time on this.

Re. Changing the public interface, I believe it should be possible to change the callers which used to call the old public method to call a new internal method, or even just online it if there are only a handful of cases. The public methods are just helpers wrapping the raw variant, so there shouldn’t be anything stopping that.

Re. Build failures - sorry about that, it was my fault. I accidentally merged a PR not realizing that branch protection wasn’t enabled. The build has been fixed and branch protection is now on.

Why not plain inline?

inline is a fairly weak hint to the compiler, inline(always) is stronger and I wanted to ensure that adding the context does not add any overhead if we disable the recursion limit.

I don't think it actually matters - the compiler is likely to inline such a trivial function

I ask because everything piece of advice I've seen on the subject recommends to use #[inline], and not #[inline(always)]. Anecdotally I've found that #[inline(always)] doesn't usually help.

@danburkert Do you consider this and other similar functions to be part of the API? Technically they are visible to users, but they are doc(hidden) and are not very user friendly.

No, anything doc(hidden) is not part of the public API, including this entire module, and the doc(hidden) methods on Message.

Any plan to make it possible to adjust the limit? TiKV uses 1000 as the default value for configuration, and we found it was occasionally changed in practice.

The old inherent `try_from` methods have been removed. - Deeply nested messages now fail decoding with an error, instead of potentially resulting in a stack overflow. The limit is set to a nesting depth of 100, and the limit can be disabled using a new `no-recursion-limit` Cargo feature.
