Why not just use name directly throughout?

name comes in as a std::string& and we want to be able to call things like .remove_suffix() on it, which are absl::string_view features.

ahhh, makes sense. I didn't realize you were substringing it.

Is there a reason we can't make this variable private?

I think we can! I thought it needed to be used in versionHelper, but I was able to rework that to need only the std::string version number instead of the whole RawStatDataSet itself.

You will probably need to initialize this below inside the scope where lock is created, which is where the stats set used to be initialized. allocator_ will probably need to be a unique_ptr as a result. This is because the lock protects the initialization. If you move it above to the initializer list, the lock won't be held while it's being constructed. Side note: are you familiar with the idea of a scope lock (std::unique_lock<Thread::BasicLockable>)?

This is a good catch. I reworked allocator_ to be a unique pointer and constructed it not-inline, and changed all references to allocator_.foo to allocator_->foo.

+  }
+  ~HotRestartNopImpl() { ::free(ptr_); }


Be careful, here. I'd be sure that that stats_allocator_ doesn't attempt to write to this memory as it's destructing. This is an artifact of the C++ order of destruction where the destructor runs first, and then the member variables are destroyed. If this is a problem, we can modify the destructor to look like this:

~HotRestartNopImpl() { stats_allocator_ = nullptr; ::free(ptr_); }

I'll do this -- is this the kind of bug I can write a test for? Or is this just intuition that this could fail?

@mrice32 when you see new statLock / stat_lock_ objects in HotRestart, HotRestartImpl, HotRestartNopImpl, and HotRestart mock objects, it's because of this line. I wanted to create and use a lock mechanism even when the restart isn't hot.

But why does it need to have its own accessor method?

I moved a lot of these tests from hot_restart_impl_test.cc since they are really unit tests on the allocator itself. A few stayed in hot_restart_impl_test.cc as they tested behavior across hot restart.

We should probably move to the way Josh allocates the memory in his tests - see here. Something like:

uint32_t num_bytes = MemoryHashSet<Stats::RawStatData>::numBytes(memory_hash_set_options_); ptr_ = new uint8_t[num_bytes];

Side note: why are you multiplying the number of bytes times the number of stats? That may be the source of your issues - you're squaring the capacity.

Great catch! I've updated this.

Just kidding, I updated this for HotRestartNopImpl. I'll update it here too.

Provide the HTTP path normalization per RFC 3986 (sans case normalization). This addresses CVE-2019-9901. The config HttpConnectionManager.normalize_path needs to be set for each HCM configuration to enable (default is off). There is also a runtime optione http_connection_manager.normalize_path to change this default when not set in HCM. Risk level: Low Testing: New unit and integration tests added.
