`Utils.ParseQueryString` already unescapes every value, and
`BaseFmt.GetQueryDecoded` unescaped it again. A value that still held a
valid percent sequence after the first pass decayed on the second: an
obfuscation password of `ob%41fs` is exported as `ob%2541fs` and imported
back as `obAfs`. Only well-formed sequences are affected, which is why the
damage is silent - `100%` and `66%ff` survive untouched.
The same function also split each pair on every `=`, and skipped the pair
unless exactly two halves came out. RFC 3986 lists `=` among the
sub-delimiters a query value may carry, so only the first one separates the
key from the value, and `HttpUtility.ParseQueryString` reads a query string
the same way. Splitting on all of them discarded a syntactically valid
pair: `?ech=AAj+DQAEAAAAAA==` was lost entirely, and so was a `plugin`
value in the non-canonical SIP002 spelling, since those are `;` separated
`key=value` lists.
v2rayN percent-encodes both on export, so its own links were never
affected; what changes is that the parser now follows the grammar instead
of discarding a pair it cannot split in two.
Splitting on the first `=` only, and reading the value the parser already
decoded, fixes both. `ParseQueryString` keeps decoding because
`ConfigHandler` reads its result directly.
`GetQueryDecoded` and `GetQueryValue` are now equivalent; they are left
separate to keep this change small, and can be collapsed if you prefer.
The Hysteria2 URI scheme makes the port optional: "The hostname and
optional port of the server. If the port is omitted, it defaults to 443."
`Hysteria2Fmt.Resolve` assigned `url.Port` straight through, and
`System.Uri` answers -1 for an unregistered scheme that carries no port,
so `hysteria2://password@hy2.example/` imported as a profile with
`Port = -1`. `ProfileItem.IsValid` rejects any port outside 1..65535, so
such a link produced a profile that could never be used, and nothing said
why.
-1 is the only value that means "the port was omitted"; a ':' with no
digits after it maps to -1 as well. An explicit ":0" parses as 0 and
keeps the fate it has today - rejected by `IsValid` - rather than being
redirected to a server the link never named.
`ResolveRealm` takes its port from `HyRealm.RendezvousPort` instead of
the URI, so it is unaffected.
The added tests cover both spellings of the scheme, with and without a
trailing slash, a bare ':', and the resulting profile's validity. Two of
them are controls: an explicit port is still preserved, and an explicit
":0" still does not turn into 443.
Follow-up to #9830: audit of all TunModeItem.EnableTun usages found
three more launch-path reads of the live mutable config where the
behavior must agree with the context snapshot that generated the
config:
- CoreConfigClashService (mihomo custom config): the tun section was
decided from the live config while the mihomo launch elevation uses
the snapshot; a mid-reload toggle could produce a config containing
tun launched without sudo, the same failure fixed in #9830. The tun
state is now passed in as a snapshot.
- CoreManager.LoadCore: the Windows RemoveTunDevice cleanup now checks
the main/pre context snapshots.
- CoreManager.WaitForProxyPort: preContext.AppConfig is a shared live
reference; use preContext.IsTunEnabled instead.
Reads that intentionally stay live: StatusBarViewModel (UI state
source), CoreConfigContextBuilder (the snapshot capture point),
GetPreSocksItem (called during snapshot construction, self-consistent),
and AppManager.StatePort2 (transient mid-reload skew only, self-heals
after reload).
* fix: sanitize system proxy exceptions to avoid macOS ExceptionsList being dropped
On macOS/Linux the exception list is comma-separated and passed to networksetup. It was only stripped of spaces, so a stray newline or a trailing comma left a malformed/empty entry. macOS configd then silently rejects the whole ExceptionsList (scutil --proxy shows no ExceptionsList), so the bypass never takes effect. Split on ',' with TrimEntries + RemoveEmptyEntries and rejoin; behavior-preserving for well-formed input. Windows path (';') is left unchanged.
Note: not built locally (no .NET SDK on hand); relying on CI.
* Update SysProxyHandler.cs

sing-box requires realm.server_url as a full URL (https://host:port).
Bare host:port caused "missing host in realm server_url" on import.
Also forward stun_servers and clear ResolveRealm success message.
Fixes#9635
* first changes
* fix: use ItemsSource for fragment packets ComboBox so value saves correctly
* feat: add customizable packet fragmentation for Xray-core
- Add fragment settings in Core tab: Packets (dropdown), Length (range), Interval (range), MaxSplit (0-10000)
- Support both 'from-to' (e.g., 50-100) and single value (e.g., 50) formats for Length, Interval, and MaxSplit
- Validation with shortened error message: 'Invalid range format. Use from-to (e.g., 50-100).'
- UI in PopupBox (materialDesign) visible only when EnableFragment is checked
- Only Xray-core supported (Mihomo/sing-box fragment code removed)
- Localization updated for 8 languages
* fix: address 2dust review feedback
- Move FragmentPacketsOptions to Global class
- Remove default values from Fragment4RayItem model (set in ConfigHandler)
- Fix Avalonia bindings: move ItemsSource and SelectedItem to code-behind
- Update ViewModel to use Global.FragmentPacketsOptions
- Remove defaults from model properties
* Adjust ui

Fetch and display tested server IP and country (with emoji) in speed tests. Adds CountryExtension for country->emoji mapping and a new IpInfoResult type; ConnectionHandler now retrieves/parses IP API results and GetRealPingTime signature adjusted. Models and entities (ProfileItemModel, ProfileExItem, SpeedTestResult) gain IpInfo fields; ProfileExManager can store test IP info. UI/UX updated: new IpInfo column in ProfilesView (desktop and Avalonia), ResUI resource strings for "IP Info", and EServerColName ordering supports IpInfo. SpeedtestService now captures IP info and forwards it to the view model via the update function.
* deps: bump ZXing.Net.Bindings.SkiaSharp from 0.16.14 to 0.16.22
Patch update to the latest stable release on the 0.16.x line. No breaking changes, no public API changes - purely internal fixes.
Verified by a full Release build of v2rayN.sln on .NET 10; no new warnings or errors are introduced.
* chore: remove NoWarn and fix .NET 10 build warnings
Removes the repository-level NoWarn suppression from Directory.Build.props and addresses the warnings that surface on top of the .NET 10 migration in #9179, keeping Debug, Release, and cross-platform publishes warning-free without suppressing warnings globally.
Changes:
- Removes <NoWarn>CA1031;CS1591;NU1507;CA1416;IDE0058;IDE0053;IDE0200</NoWarn> from Directory.Build.props.
- Annotates Windows-only APIs with [SupportedOSPlatform] and [SupportedOSPlatformGuard] so CA1416 accepts that the Windows surface is gated behind Utils.IsWindows() / Utils.IsNonWindows().
- Splits Utils.SetUnixFileMode into a cross-platform wrapper and a private [UnsupportedOSPlatform("windows")] implementation so File.SetUnixFileMode never reaches the analyzer on Windows builds.
- Adds a parameterless constructor to MessageBoxDialog so Avalonia's runtime XAML loader (AVLN3001) can instantiate the dialog.
- Moves the WPF high-DPI configuration from app.manifest to <ApplicationHighDpiMode>PerMonitorV2</ApplicationHighDpiMode> in v2rayN.csproj, fixing WFO0003.
- Adds global using System.Runtime.Versioning; to ServiceLib and v2rayN.Desktop so the platform attributes are usable project-wide.
* test: make cycle dependency tests locale-independent
Accept the localized Russian cycle dependency diagnostic in CoreConfigContextBuilderTests so the assertions pass when tests run under a Russian UI culture.
* fix: tighten Unix platform handling
Adds Linux and macOS platform guards so the analyzer can narrow calls through Utils.IsLinux() and Utils.IsMacOS().
Marks the Linux/macOS autostart and system proxy helpers with explicit platform attributes.
Updates Utils.GetSystemHosts() to read /etc/hosts on Linux and macOS while keeping the existing Windows hosts and hosts.ics merge behavior.
