Added `lockAcquired` flags in `PluginsManifest.cs` and `Main.cs`
to ensure semaphore locks are only released if successfully
acquired, preventing potential runtime errors. Updated `finally`
blocks to conditionally release locks based on these flags.
Removed redundant cancellation check in `EverythingAPI.cs` to
simplify code, assuming cancellation is handled elsewhere. These
changes enhance reliability and maintainability of the codebase.
Added a `catch` block for `OperationCanceledException` in
`PluginsManifest.cs` to ignore canceled operations. Updated
`EverythingAPI.cs` to use cancellation tokens with `_semaphore.WaitAsync`
and handle cancellations by exiting the method cleanly with `yield break`.
Updated `_semaphore.WaitAsync` in `EverythingAPI.cs` to accept a `CancellationToken` and handle `OperationCanceledException` gracefully, returning `false` instead of propagating the exception.
Refactored locking mechanisms in `Main.cs` to use `CancellationToken` for `_win32sLock` and `_uwpsLock`. Added `try-catch` blocks to handle `OperationCanceledException` and ensure proper lock release. Methods now return `emptyResults` when operations are canceled.
Updated comments to explain the rationale for not directly passing
CancellationToken to methods and instead checking
IsCancellationRequested within locks. This prevents unexpected
OperationCanceledException. Changes made in EverythingAPI.cs
(IsEverythingRunningAsync) and Main.cs (Win32 and UWP program
preparation). No functional changes to the code.
Added comments in `EverythingAPI.cs` and `Main.cs` to explain
why `CancellationToken` is not directly passed to semaphore
locks, preventing unexpected `OperationCanceledException`.
Updated debug log messages in `Main.cs` for better clarity,
including changing "Start handling programs" to "Start querying
programs". Removed redundant log messages to improve logging
consistency.
Simplified the `if` statement that checks for token cancellation
by condensing it into a single line. This improves code readability
and eliminates unnecessary line breaks.
Enhanced cancellation handling by adding `token.IsCancellationRequested` checks to improve responsiveness. Refactored locking mechanisms for `_win32sLock` and `_uwpsLock` using `try-finally` blocks to ensure proper acquisition and release, improving thread safety and preventing deadlocks.
Reorganized Win32 and UWP program querying logic for better modularity and readability. Replaced shared collection access with local variables to improve clarity and maintain thread safety. Simplified empty result handling by directly returning `emptyResults` when canceled.
Removed redundant debug log statements to reduce verbosity and updated remaining logs for clarity. Suppressed unused result warnings by replacing direct calls to `EverythingApiDllImport.Everything_GetMajorVersion()` with null-coalescing assignments.
Removed the `CancellationToken` parameter from `WaitAsync` calls
on semaphores in `EverythingAPI.cs` and `Main.cs`. This change
eliminates cancellation support for semaphore waits, likely due
to a design decision prioritizing simplicity or avoiding issues
with cancellation handling.
In `EverythingAPI.cs`, `WaitAsync(token)` was replaced with
`WaitAsync()` in two methods. Similarly, in `Main.cs`, the
`WaitAsync` calls for `_win32sLock` and `_uwpsLock` were updated
to remove the `token` parameter.
Note: This change may impact the ability to gracefully handle
cancellation during semaphore waits.
