* Start using Github Actions
Build on windows and linux. Cannot build for macos,
since the builders only support xcode 10+ which dropped
x86 support.
* Build sourcepawn tooling as separate package
Upload build artifacts containing only spcomp and the includes.
This adds a new `--scripting-only` flag to configure.py which skips
everything and goes straight to building spcomp and packaging the
include folder with it.
* Only run the workflows for the master branch
* Split common operations into PackageHelpers file
Don't duplicate the code for packaging releases for the tooling-only packages. Instead use a common `PackageHelpers` class which provides the functionality common to both packages.
This replaces the explicit list of files to package with a directory scan, so we don't have to list them all.
The pgsql sql-init-scripts were missing from the release package before, so they were added here as well. Three scripts from the testsuite were missing from the explicit list (mapdisplayname, floats, findmap), so they're now included.
* Fix Python 2 compatibility
os.scandir is Python 3 only.
* Execute ConVarQueryFinished if client disconnects
So people passing handles to the extra data can close them, adds a new return value to check if this happened

* Harden plugin loading path requirements
Restrict loading of plugins to the `sourcemod/plugins` folder and require the `.smx` file extension.
Symlinks inside the `plugins` folder are fine.
This behavior was abused as part of justCTF 2020 in the PainterHell challenge by cypis. Thank you!
* Restrict extension loading to extensions folder
* Add NULL file extension check in LoadExtension
hi @KyleS
This is a pretty big diff because SourceMod had lots of multi-arch
workarounds that can now go away. I've also changed 'x64' to 'x86_64' in
many places since this is how AMBuild normalizes it, and it's far too
late to pick the shorter string, so we might as well suck it up.
The --target-archs parameter has been replaced with --targets. It works
the same way.
The default behavior for SDK inclusion is now "present" instead of
"all" since this lowers the burden of storing many SDKs. Official builds
will still be made with --sdks=all.
* Add basic Insurgency support on Windows x64
This allows SourceMod to load on x64 Insurgency. There are still a lot of variable truncation warnings that have to be dealt with.
* Fix 32bit builds
* Compile MySQL extension as well
The hack for __iob_func being removed from the core runtime, but required by the old mysql we're building against can be simplified a lot due to the `_ReturnAddress` intrinsic available since MSVC 2015.
* Don't include the offset we want to extract in the signature
When creating our own "owned and local" protobuf message in `StartProtobufMessage`, `m_FakeEngineBuffer` is used to track that message. In `EndMessage` the message is optionally converted to a "private" one with the right abi on osx and passed to the engine's `SendUserMessage`. On linux and windows the same message as in the `m_FakeEngineBuffer` is passed though without conversion. `engine->SendUserMessage` has a vtable hook which sets `m_FakeEngineBuffer` to the passed argument.
`m_FakeEngineBuffer` frees the message it previously held, since it's "owned" from `StartProtobufMessage`, but that's the same one that's passed in as argument so a use-after-free in the engine happens when the now-freed message pointer is forwarded to the real `SendUserMessage` in the engine.
The message created in `StartProtobufMessage` wasn't free'd at all when hooks are blocked too. This fix moves the message buffer into a local variable which is destroyed at the end of the function.
Fixes#1286 and #1296
On SDKs which use protobufs, the engine has objects compiled against a specific
version of protobuf. Normally this is fine, we take care on Linux to use the
same C++ ABI. On macOS however, we use libc++ to enable C++11 functionality,
whereas the protobuf library has been compiled with libstc++. These ABIs are
not compatible.
To address the problem, we introduce PbHandle. PbHandle is a wrapper around
protobuf::Message with two added pieces of state: whether or not the handle
"owns" the message (and can free it in its destructor), and whether or not
the handle was created by the engine (private) or created by SourceMod
(local).
Whenever we transfer a protobuf::Message pointer to SourceMod, we must take
care to convert it to a Local version first. Whenever we transfer a protobuf
pointer to the engine, we must convert it to a Private handle.
For platforms with no ABI differences (almost all of them), the handle is a
no-op. The private and local localities are compatible and no translation
takes place.
On macOS, CS:GO does require translation. SourceMod loads a tiny shim
library that contains a copy of the protobuf sources compiled against the
game's ABI. It then provides serialization and deserialization methods.
SourceMod must not interact with the game's protobuf objects without first
going through this proxy library.
Note that PbHandle is not quite like unique_ptr. It can be converted into a
PbHandle that does not destroy the underlying object. This is mainly because
UserMessages.cpp has rather complex state, so it is useful to track locality
without destroying an object. An unowned PbHandle must not outlive the
owning PbHandle.
