98 Serialization sanitizer support #101
Conversation

Also, I looked over the corresponding bits in the clang tool, and they seem reasonable. |
|
There's a potential corner case of objects with empty-base optimizations in play, but that's so obscure as to likely be irrelevant. |

This side of things all looks good to me. |

@PhilMiller @cz4rs Can you guys take a look at this? I've done a major overhaul of this code. I'm splitting up the concerns between the type-specific traversal for sanitization and the sanitizer runtime logic. Checkpoint will contain the typed overloads at all times. This means one may use a stock VT/Checkpoint and then enable the sanitizer later. The sanitizer runtime itself ( |

This won't be merged until the runtime is complete in the other repo and I confirm this is the correct interface that we need for that work properly. |

| extern Runtime* rt(); | ||

| /// function that informs sanitizer if its enabled |

| // resolve actual \c serialize methods without invoking the partial | ||

I think this comment may need more elaboration. I think I kinda get what's going on, but would prefer a full explanation.

Would it make sense to have this be a member of the Runtime object?

These have to be C functions because they are LD preloaded by the serializer runtime.

Could you point me at where you picked up that constraint? That doesn't sound right to me, since LD_PRELOAD should just be importing whatever symbols it finds in a foo.so library into the list that ld.so will resolve against. If those are C function names or C++ mangled names shouldn't matter.
That said, this isn't a big deal.

Broadly, I think this looks very good. I'll be happy to see this tidied up and merged. |

I think it would be preferable to do auto rt = checkpoint_sanitizer_tr() once here, and then just rt->method()

One important check - does this work if one doesn't include the Otherwise, I think this is ready to move forward, modulo my remarks about some comments and style. |
