Using ES6 Classes broke userland code. Revert back to functions.
This is an alternative to #13370

/cc @mcollina@addaleax@watilde

Technically this would be semver-major, but it fixes a regression caused by a semver-major in 8.x, so it would be semver-patch.

Fixes: #13358
Refs: #13370

Btw, I plan to do a quick 8.0.x or 8.1.x release on Tuesday of next week that'll hopefully include this fix.

I don't think this is needed since Zlib is not explicitly exported and is used only as a base "class" inside this module. Removing it will also help performance-wise.

I think we had these two descriptors at here previously.

* src: use explicit imports Replace `using namespace lldb` with explicit `using lldb::<name>` imports. * test: fix scan-test.js with node >= 8.1.0 The object change that commit b73e042 ("src,test: support node.js >= 8") from April addressed has been reverted again in 8.1.0. Update the test. Refs: nodejs/node#13374 * src: print builtins and unnamed stack frames Previously, `v8 bt` would exclude frames that didn't map to a C++ symbol or a JS stack frame. llnode does not currently know how to identify the stack frames of V8 builtins so those were omitted as well. This commit makes those stack frames visible and introduces a heuristic (in lldb >= 3.9) where frames whose PC is inside a WX memory segment are assumed to belong to V8 builtins. Fixes: #99 * fixup! SBMemoryRegionInfo is lldb >= 3.9 Fix: #99 PR-URL: #104 Reviewed-By: Fedor Indutny <[email protected]> Reviewed-By: Colin Ihrig <[email protected]>

This commit introduces a mutex field on the ManagedEVPPKey class intended to be used when multiple threads require access to an OpenSSL EVP_PKEY object. The motivation for this came from the work being done to upgrade Node.js to OpenSSL 3.0. OpenSSL objects, like EVP_PKEY, are not thread safe (see refs for details). In versions prior to OpenSSL 3.0 this was not noticeable and did not cause any issues (like incorrect logic or crashes), but with OpenSSL 3.0 this does cause issues if access to an EVP_PKEY instance is required from multiple threads without locking. In OpenSSL 3.0 when the evp_pkey_downgrade function is called, which downgrades an EVP_PKEY instance to a legacy version, it will clear all the fields of EVP_PKEY struct except the lock (nodejs#13374). But this also means that keymgmt and keydata will also be cleared, which other parts of the code base depends on, and those calls will either fail to export the key (returning null) or crash due to a segment fault. This same code works with OpenSSL 1.1.1 without locking and I think this is because there is no downgrade being done in OpenSSL 1.1.1. But even so, as far as I can tell there are no guarantees that these object are thread safe in 1.1.1 either and should be protected with a lock.
