This commit refines the platform-aware bits of the .NET 10 dependency
modernization stack added earlier in this PR. It introduces no new
NuGet packages and does not change any pinned versions: dotnet list
package --outdated against v2rayN.sln returns only the eight Avalonia
12.x packages, all of which are explicitly out of scope for this PR.
ServiceLib/Common/Utils.cs:
- Annotate IsLinux() with [SupportedOSPlatformGuard("linux")] and
IsMacOS() with [SupportedOSPlatformGuard("macos")] so the analyzer
can narrow the platform context inside Linux/macOS guards in the same
way it already does for Utils.IsWindows().
- Rewrite GetSystemHosts() as a cross-platform helper. Previously it
unconditionally tried to read C:\Windows\System32\drivers\etc\{hosts,
hosts.ics}, which silently returned an empty dictionary on
Linux/macOS. The new implementation reads /etc/hosts on those
platforms, fixing UseSystemHosts=true being a silent no-op outside
Windows. Behavior on Windows is unchanged (still merges hosts and
hosts.ics).
ServiceLib/Handler/AutoStartupHandler.cs:
- Mark the Linux helpers (ClearTaskLinux, SetTaskLinux,
GetHomePathLinux) with [SupportedOSPlatform("linux")] and the macOS
helpers (ClearTaskOSX, SetTaskOSX, GetLaunchAgentPathMacOS,
GenerateLaunchAgentPlist) with [SupportedOSPlatform("macos")] for
symmetry with the Windows helpers in the same file. The dispatch in
UpdateTask is already gated by Utils.IsWindows / IsLinux / IsMacOS,
whose new SupportedOSPlatformGuard attributes make these annotations
enforceable by the analyzer.
ServiceLib/Handler/SysProxy/ProxySettingLinux.cs and
ServiceLib/Handler/SysProxy/ProxySettingOSX.cs:
- Mark the classes with [SupportedOSPlatform("linux")] and
[SupportedOSPlatform("macos")] respectively. Both are reachable only
through SysProxyHandler.UpdateSysProxy under the corresponding
platform guard.
ServiceLib/Manager/AppManager.cs:
- Call SQLitePCL.Batteries_V2.Init() at the top of InitApp() in
addition to the existing call in SQLiteHelper's static constructor.
The call is idempotent, so it cooperates with that static
constructor; the duplication is intentional defense-in-depth so that
any future code path which reaches the database without going through
SQLiteHelper (background services, tests, future utilities) will
still find an initialized native provider rather than throwing
"Library not initialized" at runtime.
ServiceLib/Manager/CoreManager.cs:
- Add a clarifying comment above the existing
[SupportedOSPlatform("windows")] field-level attribute on
_processJob, explaining that the attribute narrows the analyzer's
platform context for every read/assign of the field and that runtime
safety is preserved by the IsWindows() guard inside AddProcessJob. No
code change.
package-rhel-riscv.sh:
- Promote the previously hard-coded SQLite amalgamation version
(sqlite_year / sqlite_ver) inside build_sqlite_native_riscv64 to two
env-overridable variables (SQLITE_AMALGAMATION_YEAR and
SQLITE_AMALGAMATION_VER) declared at the top of the script next to
SKIA_VER and HARFBUZZ_VER.
- Set the defaults to 2025 / 3500400, which corresponds to SQLite
3.50.4 and matches SourceGear.sqlite3 3.50.4.5 used on the other
RIDs (x64/arm64/macOS). Previously the script downloaded SQLite
3.53.0 amalgamation on RISC-V, which left RISC-V users on a
different SQLite minor version than every other platform shipped
from this repository. The accompanying comment block documents the
mapping rule between SourceGear.sqlite3 X.Y.Z.W and the
SQLITE_AMALGAMATION_* values, so the next bump can be done in two
coordinated places (this script and Directory.Packages.props)
without drift. The version can still be overridden per-build via
environment variables for ad-hoc testing on RISC-V.
Verification
------------
- dotnet restore + dotnet build v2rayN.sln -c Release: 0 errors,
1 warning (CS8625 in GlobalHotKeys submodule, pre-existing,
out-of-scope of this PR).
- dotnet test ServiceLib.Tests: 41/41 passed.
- dotnet publish v2rayN.Desktop.csproj for linux-x64 and osx-x64,
and v2rayN.csproj for win-x64: all succeed with no new warnings.
- dotnet list package --outdated against v2rayN.sln: only the eight
Avalonia 12.x packages appear; none are eligible while this PR
stays on the Avalonia 11.x branch.
Replace ReactiveUI.Fody with ReactiveUI.SourceGenerators, migrate reactive properties, and remove Fody weaver configuration.
Move SQLite from SQLitePCLRaw.bundle_green to SQLitePCLRaw 3.x using config.e_sqlite3 and SourceGear.sqlite3 with explicit initialization.
Update related package versions, set invariant xUnit culture, and refresh RHEL RISC-V packaging versions.
