Fix: Startet nicht / MySQL-Timeout ohne UI (Config- & Startup-Härtung)
Ursachen (App startete aus bin/ bzw. per Doppelklick ohne UI): 1. appsettings.Local.json (MySQL-Connection) wurde NICHT ins Output kopiert und nur relativ zum Arbeitsverzeichnis geladen -> leere Connection -> Pomelo fiel auf localhost:3306 zurueck -> "Connect Timeout expired". 2. ServerVersion.AutoDetect(conn) oeffnet beim Options-Bau eine blockierende DB-Verbindung -> haengt/crasht den Start, wenn die DB nicht erreichbar ist. 3. CopyTradingEngine.StartAsync lud den MarketCache ungeschuetzt -> DB-Fehler riss AppHost.Start() ab, bevor die UI erschien. Fixes: - csproj: appsettings.Local.json mit ins Output kopieren (CopyToOutputDirectory). - Program: UseContentRoot(AppContext.BaseDirectory) -> Config wird immer neben der EXE gesucht (Main + Smoke-Test). - ServerVersion fest gepinnt: DatabaseServerVersion.Value = MariaDB 11.8.6 (wie am Server erkannt); AddCorePersistence + CopyTradingModule nutzen sie statt AutoDetect. Kein blockierender Connect mehr beim Start. - CopyTradingEngine-Preload in try/catch: DB-Fehler bricht den Start nicht mehr ab. - Neuer Diagnose-CLI --db-version (gibt @@version aus). Verifiziert: --smoke-ui aus fremdem Arbeitsverzeichnis laeuft gruen (3 Accounts / 32 Trader hydriert, alle Views + Launcher OK). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

Microsoft ResX Schema
|
||||
|
||||
Version 2.0
|
||||
|
||||
The primary goals of this format is to allow a simple XML format
|
||||
that is mostly human readable. The generation and parsing of the
|
||||
various data types are done through the TypeConverter classes
|
||||
associated with the data types.
|
||||
|
||||
Example:
|
||||
|
||||
... ado.net/XML headers & schema ...
|
||||
<resheader name="resmimetype">text/microsoft-resx</resheader>
|
||||
<resheader name="version">2.0</resheader>
|
||||
<resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
|
||||
<resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
|
||||
<data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>
|
||||
<data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
|
||||
<data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
|
||||
<value>[base64 mime encoded serialized .NET Framework object]</value>
|
||||
</data>
|
||||
<data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
|
||||
<value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
|
||||
<comment>This is a comment</comment>
|
||||
</data>
|
||||
|
||||
There are any number of "resheader" rows that contain simple
|
||||
name/value pairs.
|
||||
|
||||
Each data row contains a name, and value. The row also contains a
|
||||
type or mimetype. Type corresponds to a .NET class that support
|
||||
text/value conversion through the TypeConverter architecture.
|
||||
Classes that don't support this are serialized and stored with the
|
||||
mimetype set.
|
||||
|
||||
The mimetype is used for serialized objects, and tells the
|
||||
ResXResourceReader how to depersist the object. This is currently not
|
||||
extensible. For a given mimetype the value must be set accordingly:
|
||||
|
||||
Note - application/x-microsoft.net.object.binary.base64 is the format
|
||||
that the ResXResourceWriter will generate, however the reader can
|
||||
read any of the formats listed below.
|
||||
|
||||
mimetype: application/x-microsoft.net.object.binary.base64
|
||||
value : The object must be serialized with
|
||||
: System.Runtime.Serialization.Formatters.Binary.BinaryFormatter
|
||||
: and then encoded with base64 encoding.
|
||||
|
||||
mimetype: application/x-microsoft.net.object.soap.base64
|
||||
value : The object must be serialized with
|
||||
: System.Runtime.Serialization.Formatters.Soap.SoapFormatter
|
||||
: and then encoded with base64 encoding.
|
||||
|
||||
mimetype: application/x-microsoft.net.object.bytearray.base64
|
||||
value : The object must be serialized into a byte array
|
||||
: using a System.ComponentModel.TypeConverter
|
||||
: and then encoded with base64 encoding.
