This PR makes it possible to disable all default dependencies for wasmtime
---------
Co-authored-by: zach <zachshipko@gmail.com>
Co-authored-by: zach <zach@dylibso.com>
This wrapper caches the result of `plugin.function_exists`, to avoid
having to load a plugin from the pool every single time just to find out
if the given function exists. It can improve performance if there are
many plugin hooks without corresponding plugin functions.
---------
Co-authored-by: zach <zach@dylibso.com>
Hello,
I encountered an error when trying to enable caching in my project, I
could not compile any Plugins due to a bad configuration file used by
the wasmtime crate (`failed to parse config file`). I managed to find
understand the error after seeing [some changes made by
wasmtime](https://github.com/bytecodealliance/wasmtime/pull/10859) and
its documentation. I was simply missing the `enabled` key from the
configuration, that has been removed from `wasmtime` (and its [cache
sister
crate](https://github.com/bytecodealliance/wasmtime/tree/main/crates/cache)).
So I added more information in the README regarding this specific issue,
and some extra behaviour that I noticed would happen regarding caching
configuration.
Hopefully this is helpful!

I know that there is already a logging example in
`runtime/examples/log_callback.rs` but I think that's not where people
go to look to figure out how the logging functionality works. At least
for me that wasn't the case :)
Previously, code that called a plugin that called a host function that
called back into the plugin would hang in an attempt to attain the lock.
Switch to `try_lock` so we can surface the error.
Upgrades from wasmtime 26 to wasmtime 27-29, allowing us to support more
versions (including the possibility of supporting future releases
without changes)
This PR adds a function to get the fuel consumed by a plugin. This is
useful for systems that want to fairly balance compute. It's my first
time doing anything in rust so let me know if something needs
improvements!

Closes https://github.com/extism/extism/issues/801
Updates the error from:
```
Unable to compile Extism plugin: incompatible import type for `extism:host/user::wrong_type`
```
to:
```
Unable to compile Extism plugin: types incompatible: expected type `(func (result i32))`, found type `(func (result i64))`
```
I wrap the `Plugin` instance in a `RwLock` and because `function_exists`
requires `&mut self`, I have to acquire a write lock everytime to just
check if a function exists, which causes lock contention.
This changes it to `&self` since it doesn't need to mutate.
`extism_compiled_plugin_new` would panic on bad manifest input (there's
a test in the python sdk [1] that hits this directly.) Catch the error and
set `errmsg` appropriately instead.
Additionally: golf the function pointer casting for the various `plugin_new` calls,
with the goal of reducing the number of allocations by leaning on iterator size
hints (and reducing the scope of `unsafe{}` use.) This part can be severed: it
introduces a breaking change. Previously `NULL` values were silently accepted in
the `functions**` list; now they fail. This maintains consistency with behavior on
"consumed" `ExtismFunction` pointer.
[1]: https://github.com/extism/python-sdk/blob/main/tests/test_extism.py#L50-L53
- Adds `extism:host/env::http_headers` to access HTTP response headers
- Adds `PluginBuilder::with_http_response_headers` to enable response
headers from Rust
- Adds `extism_plugin_allow_http_response_headers` to enable response
headers using the C API
TODO:
- [x] Update a PDK to use `extism:host/env::http_headers` so I can test
this
Updates the kernel to only scan for free blocks before a `memory.grow`
operation, this should improve performance of `alloc` by not iterating
over every block for each allocation.
An alternative to #763, this PR allows an initial `wasmtime::Config` to
be passed in when building a plugin. Some of these values may be
overwritten by the Extism runtime, but it allows for things like static
memory size and other low-level details to be handled directly instead
of us having to wrap every option ourselves.
- Checks error results to determine if a plugin ran out of fuel, if the
fuel is 0 after we get the error, then we return an out of fuel error
message instead.
- Updates `extism_plugin_error` to check `Plugin::error_msg` regardless
of the kernel's error state
Both [as_ptr][as_ptr] and [as_mut_ptr][as_mut_ptr] are allowed to return
a dangling raw pointer when the Vec size is 0.
The idea is that you should guard that read checking the size. This
probably works well in most cases, but at the very least in the
java-sdk, the JNA machinery tries to be helpful and it dereferences the
pointer, causing a SIGSEGV.
The solution is to check if the resulting vector is empty and return
null instead. A new, empty vector would be better, but I think that
would not solve the problem, because the problem is caused by a new,
empty vector in the first place.
Caveat: this might break consumers downstream.
On the other hand: consumers that do not check for the nInput, nOutput
counts are just waiting to explode, like JNA.

Updates plugins to allocate a single `ExternRef` for the host context up
front, to avoid running into the `failed to allocate externref` error
from Wasmtime
Updates the requirements on
[cbindgen](https://github.com/mozilla/cbindgen) to permit the latest
version.

This is a rough POC for allowing people to whitelist a dir as readonly.
When the source path is prefixed with `ro:`, the dir is considered as
readonly. This preserved backward compatibility. This suggestion came up
in https://github.com/extism/go-sdk/pull/1#discussion_r1276700587
Readonly:
```rs
let manifest = Manifest::new([url])
.with_allowed_path("ro:D:/x/rust/fs/data".to_string(), "/data")
.with_config_key("path", "/data/data.txt");
```
```
