feat(dotnet-windows): add independent .NET 8 + Avalonia implementation reference - #20
ALIve114514awa wants to merge 28 commits into
Conversation
…n reference - Add NeriPlayer.Windows (.NET 8 + Avalonia) as an independent technology stack reference under dotnet-windows/, parallel to the official Tauri (Rust + Vue) implementation - Does not participate in the root pnpm/cargo build system - Includes solution skeleton, EF Core-ready data layer, playback engine interfaces, core data models and unit tests

📝 WalkthroughWalkthroughAdded a .NET 8 Windows solution with Avalonia startup, LibVLC playback, reactive playback control, platform APIs, downloads, audio effects, FFT analysis, EF Core SQLite persistence, architecture documentation, and unit/integration tests. Changes.NET Windows player foundation
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟠 High · up to The new Windows implementation adds playback, downloads, login, search, and persistent recovery behavior, but the current version has unresolved failures that can reject Bilibili requests, prevent QR login, duplicate search results or lyrics, leave orphaned recovery data, and disrupt playback or queue navigation. These affect core user flows, so the PR is not merge-ready until the issues are fixed or explicitly accepted. Sequence Diagram(s)sequenceDiagram

package versions in Directory.Packages.props: change the README entry from 8.x
to 3.8.0, unless the intended dependency is 8.x, in which case update the
LibVLCSharp package pins instead.
In `@dotnet-windows/src/NeriPlayer.App/MainWindow.axaml`:
- Around line 7-8: Replace the generated Avalonia window title and “Welcome to
Avalonia!” content in MainWindow with the NeriPlayer application title and
intended initial content.

- Around line 10-18: Update the song-key construction in SongIdentity to reject

songs must not produce local| without a path, YouTube must not produce ytm| when
ExtractYouTubeVideoId fails, and Bilibili must not produce bilibili|| when
identifiers are absent. Use a collision-safe fallback containing the original
URI and/or Id, and add tests covering missing and unsupported source metadata.

Inline comments:
In `@dotnet-windows/Process.md`:
- Around line 556-578: The StableKey example’s bilibili and youtube_music
branches lack the collision-safe Id fallback. Update SongIdentity.StableKey so
both branches use the current implementation’s complete metadata and fallback
behavior, matching the tested collision-safe identity format.
- Around line 421-429: Update the URL 保鲜 documentation and the
PlayerManager.ResolveMediaUri behavior consistently: implement resolving a fresh
StreamUrl before LoadAsync, including the documented 10-second refresh cooldown,
or relabel the behavior as planned if refresh is not implemented. Do not claim
background refresh is available while ResolveMediaUri only logs “refresh needed”
and returns the stale URL.
- Around line 636-641: Update the startup flow in AppStartup.BuildServices() to
register the DbContext and invoke Database.Migrate() during application
initialization, or revise the documentation to mark automatic migration as
planned; ensure the documented behavior is not presented as currently available.
- Around line 542-545: Mark SyncMembershipTokens as planned in the Process.md
implementation plan, without adding model, persistence, serialization, or test
changes.
- Around line 832-856: Separate NetEase signing from Bilibili WBI signing:
remove the WBI signing entry from the NetEase section, and update
NeteaseCrypto.cs and milestone 6.2 so NetEase URL resolution is described as
WeAPI-encrypted rather than WBI-signed. Keep WBI references only for Bilibili
flows.
In `@dotnet-windows/src/NeriPlayer.Core/NeriPlayer.Core.csproj`:
- Line 10: Add a Windows LibVLC runtime dependency for NeriPlayer.App,
preferably using the VideoLAN.LibVLC.Windows package alongside the existing
LibVLCSharp reference, or an equivalent publish/output-copy configuration that
supplies the native binaries without relying on D:\libs\vlc-3.0.20. Ensure
VlcPlaybackEngine initialization can locate the runtime in deployed builds.
Apply the same fix in
`@dotnet-windows/src/NeriPlayer.Core/Player/Engine/VlcPlaybackEngine.cs` around
lines 21 - 29: Covers the developer-local fallback and null LibVLC
initialization behavior.
Apply the same fix in `@dotnet-windows/Process.md` around lines 1204 - 1208:

In `@dotnet-windows/src/NeriPlayer.Core/Player/Engine/VlcPlaybackEngine.cs`:
- Around line 54-56: Make VlcPlaybackEngine honest about unsupported playback
features: in
dotnet-windows/src/NeriPlayer.Core/Player/Engine/VlcPlaybackEngine.cs lines
54-56, publish FftData or remove that stream; at lines 60-66, apply

dotnet-windows/src/NeriPlayer.Core/Player/Engine/IPlaybackEngine.cs lines 7-12
and 24-31, retain only options and capabilities with defined behavior across
production implementations.
- Around line 75-81: Update ApplyEqualizer so the clamped gain values passed to
Equalizer.SetAmp remain in decibels without multiplying by 100f; preserve the
existing ±20 range and band iteration.
- Around line 43-51: Update the VLC event handlers in VlcPlaybackEngine so all
_events.OnNext calls are delivered through a serialized scheduler or dispatcher
outside the LibVLC callback thread. Preserve event ordering and ensure observers
cannot synchronously call _player.Play or other LibVLC operations before the
originating callback returns.
In `@dotnet-windows/src/NeriPlayer.Core/Player/PlayerManager.cs`:
- Around line 154-175: Update ResolveMediaUri to stop using the manager-wide
_lastUrlRefreshAt timestamp and instead use a per-URL acquisition timestamp
stored on SongItem. Delegate expiry evaluation to
MediaUrlRefreshPolicy.ShouldRefresh, and when refresh is required either refresh
song.StreamUrl or add a clear TODO for the follow-up refresh implementation; do
not return an expired URL unchanged.
- Around line 190-212: Update NextAsync and PreviousAsync to return immediately
when the queue is empty, preventing any index calculation or PlayAtIndexAsync
call. In NextAsync, honor RepeatMode.One by replaying the current item through
PlayAtIndexAsync instead of advancing or stopping, and use Random.Shared for
shuffle selection while preserving existing RepeatMode.All and normal navigation
behavior.
In `@dotnet-windows/src/NeriPlayer.Core/Player/Policy/TrackEndDedupPolicy.cs`:
- Around line 23-29: Make TrackEndDedupPolicy.TryConsume atomic by guarding the
_lastEndAt check-and-update sequence with a private lock, so concurrent
EndReached events cannot both return true; preserve the existing GuardWindow
behavior and return values.
In `@dotnet-windows/src/NeriPlayer.Data/Database/NeriDbContext.cs`:
- Around line 50-59: Update the PlaybackStatsEntity and StatBucketEntity
mappings in NeriDbContext.OnModelCreating to reference SongEntity through
SongId, configure both relationships with cascade deletion, and mark
PlaybackStatsEntity.SongId as non-generated. Regenerate the initial migration
and model snapshot, then add tests covering orphan-row rejection and cascading
deletion of statistics when a song is removed.
In `@dotnet-windows/src/NeriPlayer.Data/Repositories/SongRepository.cs`:
- Around line 20-28: Update UpsertAsync to make the StableKey upsert atomic
under concurrent DbContexts by using INSERT ... ON CONFLICT(StableKey) DO UPDATE
or by reloading and updating the existing row after handling a unique-constraint
conflict; add a two-context concurrency test. Replace
CurrentValues.SetValues(song) with an update that excludes the primary-key Id,
and add a test confirming detached input with Id == 0 does not modify or replace
the stored key.

Do not document URL refresh as implemented until the resolver performs it.
The supplied PlayerManager.ResolveMediaUri implementation only records that StreamUrl is stale, logs "refresh needed", and returns the old URL. It does not resolve a new URL or enforce the documented refresh cooldown. Either implement refresh before LoadAsync, or label this behavior as planned.

Keep the StableKey example aligned with the collision-safe implementation.
The documented bilibili and youtube_music branches still interpolate incomplete metadata without an Id fallback. The PR summary says the implementation now uses a collision-safe fallback and adds tests. Update this sample to match the current implementation, or future changes can reintroduce duplicate identities during deduplication and sync.

🧩 Analysis chain
🌐 Web query:
Verify which NetEase Cloud Music endpoints use WeAPI or EAPI signing and which Bilibili endpoints require WBI signing. Compare the result with dotnet-windows/Process.md Lines 832-856.
💡 Result:
NetEase Cloud Music and Bilibili utilize specific request signing mechanisms to manage API security and prevent unauthorized access. NetEase Cloud Music Signing: The platform differentiates its API endpoints based on the client type, primarily using WeAPI and EAPI signing [1][2]. 1. WeAPI: Primarily used for web-based interfaces and mini-programs [1][2]. It employs a two-layer encryption approach involving AES-CBC and RSA for key exchange [1]. 2. EAPI: Targeted at PC and mobile clients [1][2]. This method uses AES-ECB encryption combined with an MD5-based signature that incorporates the request path and parameters [1][3]. Bilibili WBI Signing: Bilibili has implemented WBI signing as a mandatory security measure for its Web API endpoints [4][5]. 1. Scope: WBI signing is required for almost all Web API query-based endpoints (e.g., search functions) [4]. Since May 26, 2025, it has been strictly enforced for all authenticated Bilibili API endpoints [5]. 2. Mechanism: Requests must include w_rid (a signature calculated via MD5) and wts (current Unix timestamp) as query parameters [4][6]. The signature is derived by sorting query parameters, appending a specific mixin_key (obtained via a separate nav API call), and hashing the result [4][7]. Regarding dotnet-windows/Process.md: The reference to Lines 832-856 in dotnet-windows/Process.md appears to be unrelated to these API signing mechanisms. The repository dotnet/runtime (which includes the Process implementation) uses these lines to define Windows-specific process management logic, such as Process.Windows.cs handling of process handles, security privileges (e.g., SetPrivilege), and termination logic [8][9][10]. There is no intersection between.NET's system process management source code and the application-layer API signing protocols used by NetEase or Bilibili.

NetEase Cloud Music API WeAPI EAPI endpoint signing documentation weapi/search/get weapi/song/lyric Bilibili WBI required endpoints x/web-interface/search/type audio/music-service-c/songs/url x/player/playurl
💡 Result:
For NetEase Cloud Music and Bilibili API endpoints, the requested signing and authentication mechanisms are summarized below. NetEase Cloud Music API NetEase utilizes two primary encryption schemes for its API endpoints: WeAPI and EAPI [1][2][3]. 1. WeAPI: Designed for web-based requests, it employs a two-layer encryption process [3]. The request data (JSON) is first encrypted using AES-128-CBC [3][4]. A randomized second key is subsequently encrypted using RSA, which is then hex-encoded as the encSecKey field [3]. This mode is commonly used for endpoints like weapi/search/get and weapi/song/lyric [4][5][6]. 2. EAPI: Used primarily for PC and mobile application traffic, this protocol is more robust [2][3]. It involves signing request parameters (including device metadata) using dynamic salts and cryptographic hashing (typically MD5) before the final payload is encrypted with AES-128-ECB [2][3][7]. Bilibili WBI Signing Bilibili uses a WBI (Web-Based Interface) signing mechanism for sensitive and high-traffic endpoints like x/web-interface/search/type and various player-related URLs [8][9]. The WBI algorithm relies on dynamic keys fetched from the x/web-interface/nav endpoint [9][10][11]. 1. Dynamic Keys: The nav endpoint provides an img_url and sub_url [8][10]. The file names of these URLs are extracted to obtain img_key and sub_key [8][9]. 2. Mixin Key: A fixed 64-integer lookup table (often referred to as MIXIN_KEY_ENC_TAB) is used to permute the img_key and sub_key into a "mixin key," of which the first 32 characters are used for signing [9][10]. 3. Signing Process: - Append a Unix timestamp (in seconds) to the request parameters as the wts field [8][12]. - Sort all query parameters (including wts) lexicographically by key [8][10][11]. - Perform URL encoding (RFC 3986, noting that spaces should be %20 and not +) [8][11]. - Concatenate the resulting query string with the mixin_key and compute the MD5 hash; this hash becomes the w_rid parameter [8][12][9]. - The final request must include both wts and w_rid in the query parameters [8][12]. Top results: [1][2][3][8][9][10]

ResolveMediaUri measures the wrong timestamp and never refreshes the URL.
_lastUrlRefreshAt records when this manager last logged staleness. It does not record when song.StreamUrl was obtained. Two consequences:
- On the first remote song,
_lastUrlRefreshAtisDateTimeOffset.MinValue, so Line 167 is always true and the log reports a stale URL with an age of centuries. - After that, the timer is global rather than per song, so a genuinely expired
StreamUrlon a different song is reported as fresh for the next 10 minutes.
The method also returns the possibly expired StreamUrl unchanged, so playback still fails with an expired link.
MediaUrlRefreshPolicy already implements this decision correctly against a per-URL timestamp, and it is unused here. Store the URL acquisition time on SongItem and delegate to MediaUrlRefreshPolicy.ShouldRefresh, then either refresh the URL or record a clear TODO for the follow-up chapter.

Make TryConsume atomic.
LibVLC raises EndReached from a native event thread. PlayerManager.OnEngineEvent calls TryConsume directly on that thread (Lines 132-137 of PlayerManager.cs). The read of _lastEndAt at Line 26 and the write at Line 27 are not atomic. If two duplicate end events arrive concurrently, both can read the old timestamp, both return true, and the player advances two tracks. That is the exact case this policy exists to prevent.
Guard the check-and-set with a lock.

Add song foreign keys for statistics rows.
PlaybackStatsEntity.SongId and StatBucketEntity.SongId have no relationship to SongEntity. The initial migration therefore creates no foreign keys for these tables. SQLite can accept orphan statistics rows, and deleting a song leaves its statistics rows behind.
Configure both relationships with cascade deletion. Configure PlaybackStatsEntity.SongId as non-generated because it must equal an existing song ID. Regenerate the initial migration and snapshot. Add tests for orphan rejection and song-delete cascades.

EF Core PropertyValues.SetValues primary key property modification existing entity key cannot be modified official documentation
💡 Result:
In Entity Framework Core, the PropertyValues.SetValues method is designed to update the property values of a tracked entity by copying them from another object or dictionary [1][2]. However, this method will throw a System.InvalidOperationException if it attempts to modify a property that is part of the entity's primary key [3][4]. The core reason for this limitation is that EF Core relies on the primary key to uniquely identify and track entity instances within the DbContext [5][6]. Modifying the primary key of a tracked entity would break the identity resolution mechanism, potentially leading to inconsistencies in the tracking graph [5]. Key Technical Points: - Behavior: When SetValues encounters a value in the source object that corresponds to a primary key property, it attempts to assign it to the tracked entity. If this assignment triggers a change to a key property, EF Core raises an exception because key properties are considered immutable while the entity is being tracked [3][4]. - Workaround: If you need to update an entity while avoiding this error, you must ensure that your update logic does not attempt to overwrite the primary key values [3]. You can achieve this by manually copying only the non-key properties or by filtering out the key properties before calling SetValues [3]. - Alternative Approaches: If the goal is to actually change the primary key of an existing entity in the database (e.g., re-keying a record), this cannot be done through standard tracking updates. Instead, you must typically delete the existing entity and insert a new one with the desired key, or use raw SQL commands to perform the update if the underlying database provider permits key modification [3]. If you are using migrations to change the schema's primary key definition itself (rather than updating a specific entity instance's key value), this must be handled by dropping and recreating the primary key constraint using migrations, which may require raw SQL depending on the database provider [7][8][9].

EF Core SQLite unique constraint SaveChanges DbUpdateException official documentation
💡 Result:
When EF Core encounters a violation of a unique constraint in a SQLite database during SaveChanges, it throws a DbUpdateException [1][2][3]. Because EF Core is designed to be database-agnostic at its core, it does not provide a built-in, platform-independent exception type specifically for unique constraint violations [4]. To handle this exception, you must inspect the InnerException, which contains the database-specific error [3]. How to handle the exception: 1. Catch DbUpdateException: Wrap your SaveChanges or SaveChangesAsync call in a try-catch block [5][3]. 2. Inspect the InnerException: Check if the InnerException is of type Microsoft.Data.Sqlite.SqliteException [4]. 3. Verify the error code: SQLite uses error code 19 to indicate a constraint violation [5][4]. You can check this by accessing the SqliteErrorCode property of the exception [4]. Example implementation: try { await context.SaveChangesAsync; } catch (DbUpdateException ex) when (ex.InnerException is SqliteException sqliteEx && sqliteEx.SqliteErrorCode == 19) { // Handle the unique constraint violation (e.g., notify user, log error) } General Considerations: - Tracking Issues: Often, unique constraint violations occur because the ChangeTracker is attempting to insert a record that already exists or is tracked inconsistently across DbContext instances [6][7][8][9]. Ensure that entities are correctly attached or loaded if they already exist in the database [10][6][7]. - Third-party Libraries: For projects requiring more robust, database-independent exception handling, community libraries such as EntityFramework.Exceptions are available, which provide specific exception types (e.g., UniqueConstraintException) for various database providers [4][9]. - SQLite Limitations: Be aware that SQLite has specific limitations regarding schema operations [11]. While this does not directly affect SaveChanges, it is important for overall EF Core SQLite integration [11].

Reject sample rates that cannot represent the 20 Hz lower bound.
If sampleRate <= 40f, maxFrequency <= 20f. The logarithmic range is then degenerate or reversed. Compute returns 64 bands that do not represent their calculated frequency ranges.

Include wts in the signed canonical parameters.
Sign documents that callers exclude wts, but Line 25 signs only query. The method cannot generate the required WBI signature when the timestamp is absent. Bilibili will reject requests that use this signature.
Add wts before canonicalization. Build the complete upstream-required canonical payload. Add a regression test with a known signature fixture.

Return the QR URL before polling for login completion.
Line 131 stores qrUrl only in a local variable. Lines 133-146 block until polling ends. Every LoginResult omits QrUrl. A caller cannot display the QR code that the user must scan.
Split QR issuance from polling, or expose a progress callback that returns qrUrl before the polling loop starts.

Do not advertise pages that this client cannot fetch.
page does not affect the request payload. Calls with page = 1 and page = 2 send the same search request. Line 73 also reports HasMore = true for every response. A paging consumer can therefore append the first result set repeatedly. Implement continuation-token paging, or return HasMore = false until paging is supported.

YouTube search results omit AudioId. The lyric cache then maps every YouTube result to youtube_music|. After one lyric source returns a result, later YouTube songs can receive that same cached lyric.

Add the DownloadEntity foreign-key relationship.
DownloadId has only an index. It has no foreign-key constraint. The migration therefore accepts orphan recovery rows. DownloadRepositoryTests.Recovery_AddAndQueryPending currently creates one with DownloadId = 1 and no download row.
