    MVCFramework Custom logg Linux

    In the create FMVC := TMVCEngine.Create I send in a custom logger like below GetLogger end,GetLogger); //GetLogger // Added the logger at this stage unit CustomLoggerConfigU; interface uses LoggerPro; // loggerpro core function GetLogger: ILogWriter; implementation uses System.IOUtils , LoggerPro.FileAppender ; function GetLogger: ILogWriter; begin Result := BuildLogWriter([ {$IFDEF MSWINDOWS} TLoggerProFileAppender.Create ( 10, 1000 , 'C:\hseqsetting\logs' ) {$ENDIF} {$IFDEF LINUX} TLoggerProFileAppender.Create ( 10, 1000 , '/etc/hseq/logs' ) {$ENDIF} ], nil,TLogType.Info); end; end. is this above what you mean with setcustomlogger ? This is an ISAPI app .so for Linux Apache. It was not able to create the file in the location I set in GetLogger But if I added a file manually and set chmod 0777 libmod_hseq2.00.dmvcframework.log to the file, it worked. But after the file logging worked, I was not able to use /dev/stdout My plan was to send the log to AWS cloud watch together with the apache log. So I have for now instead created a custom logger for MYSQL. I can of course be my little knowledge of the framework, and this is not an issue, but I was not able to find any examples for ISAPI Linux using log, and based on my reading I could not make it work. Do you still think I should make it an issue? Also the linux docker is Ubuntu 18.04

    MVCFramework Custom logg Linux

    Also if someone needs it later I added the logger in the create part of TMVCEngine procedure TMyWebModule.WebModuleCreate(Sender: TObject); begin FMVC := TMVCEngine.Create(Self, procedure(Config: TMVCConfig) begin // session timeout (0 means session cookie) Config[TMVCConfigKey.SessionTimeout] := '0'; // default content-type Config[TMVCConfigKey.DefaultContentType] := TMVCConstants.DEFAULT_CONTENT_TYPE; // default content charset Config[TMVCConfigKey.DefaultContentCharset] := TMVCConstants.DEFAULT_CONTENT_CHARSET; // unhandled actions are permitted? Config[TMVCConfigKey.AllowUnhandledAction] := 'false'; // default view file extension Config[TMVCConfigKey.DefaultViewFileExtension] := 'html'; // view path Config[TMVCConfigKey.ViewPath] := 'templates'; // Enable Server Signature in response Config[TMVCConfigKey.ExposeServerSignature] := 'true'; end,GetLogger); //GetLogger // Added the logger at this stage FMVC.AddController(TMyController);

    I will also have a look at Restappender, maybe it is a better solution for me...

    MVCFramework Custom logg Linux

    The problem was access in my docker file I added the file libmod_hseq2.00.dmvcframework.log and chmod 0777 libmod_hseq2.00.dmvcframework.log then it works so now it seems to log fine to this file /var/log/hseq/libmod_hseq2.00.dmvcframework.log But I got a new problem I would like to send this file to "stdout" Tried using this command RUN ln -sf /dev/stdout /var/log/hseq/libmod_hseq2.00.dmvcframework.log It gives me no error but no logging is showing using docker logs <dockername> I did find something about it maybe not working because it's not in PID1? Any idea
  5. Hi , I am trying to make a custom logg work in Linux , but it make the ISAPI stop running It works great in windows. I have this CustomLoggerConfigU.pas unit CustomLoggerConfigU; interface uses LoggerPro; // loggerpro core function GetLogger: ILogWriter; implementation uses System.IOUtils , LoggerPro.FileAppender // loggerpro file appender (logs to file) {$IFDEF MSWINDOWS} , LoggerPro.OutputdebugStringAppender {$ENDIF} // loggerpro outputdebugstring appender (logs to the debugger) ; function GetLogger: ILogWriter; begin Result := BuildLogWriter([ {$IFDEF MSWINDOWS} TLoggerProFileAppender.Create(10, 1000, 'C:\hseqsetting\logs') {$ENDIF} {$IFDEF LINUX} TLoggerProFileAppender.Create(10, 1000, '/etc/hseq/logs') {$ENDIF} ], nil,TLogType.info); end; end. and in my webmodule i have added MVCFramework.Logger to uses and use the following code to trigger SetDefaultLogger ........ procedure TMyWebModule.WebModuleDestroy(Sender: TObject); begin FMVC.Free; end; initialization DataModuleDict:= TDataModuleDict.Create(nil); DataModuleDict.initDict; SetDefaultLogger(GetLogger); finalization DataModuleDict.Free; end. System run ok if I remove SetDefaultLogger(GetLogger); , but if it is present i get this line in terminal, but after it hang root@5e5f9a598ac5:/etc/hseq/logs# cat libmod_hseq2.00.dmvcframework.log 2022-03-22 18:57:54:100 [TID 274930554752][INFO ] Custom Logger initialized [dmvcframework] root@5e5f9a598ac5:/etc/hseq/logs# So its initialized but then hole system hang... not able to run before i comment out line below //SetDefaultLogger(GetLogger); Is this not the correct way to do this on Linux ? thanks in advance

    Delphimvcframework and contenttype

    Great Thanks 🙂
  7. I have this code procedure THseqScimController.createUser; var aUser : TUser; begin aUser := Context.Request.BodyAs<TUser>; try if UserScimHandleClass.CreateUser(aUser) then begin Render(aUser,false); Context.Response.StatusCode:=201; end else raise EMVCException.Create(HTTP_STATUS.Conflict,'Conflict'); finally aUser.Free; end; End; It works great from postman with this content type application/json But when request come from Microsoft Azure it have this content type application/sim+json And it gives me an error on aUser := Context.Request.BodyAs<TUser>; Body content type not supported… Is there a way to change this application/sim+json to application/json or to add application/sim+json as a supported type ? I guess other option is to parse json and build the object myself Thanks

    Deflate zip

    Hi, I am trying to make a SAML request. Anyone now how to deflate a string in Delphi ? AuthNRequest := '<samlp:AuthnRequest xmlns:samlp="urn:oasis:names:tc:SAML:2.0:protocol"'+ 'xmlns:saml="urn:oasis:names:tc:SAML:2.0:assertion" ID="ONELOGIN_809707f0030a5d00620c9d9df97f627afe9dcc24" Version="2.0" '+ 'ProviderName="SP test" IssueInstant="2014-07-16T23:52:45Z" Destination="http://idp.example.com/SSOService.php" ProtocolBinding="urn:oasis:names:tc:SAML:2.0:bindings:HTTP-POST"'+ ' AssertionConsumerServiceURL="http://sp.example.com/demo1/index.php?acs">'+ '<saml:Issuer>http://sp.example.com/demo1/metadata.php</saml:Issuer>'+ '<samlp:NameIDPolicy Format="urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress" AllowCreate="true"/>'+ '<samlp:RequestedAuthnContext Comparison="exact">'+ '<saml:AuthnContextClassRef>urn:oasis:names:tc:SAML:2.0:ac:classes:PasswordProtectedTransport</saml:AuthnContextClassRef>'+ '</samlp:RequestedAuthnContext>'+ '</samlp:AuthnRequest>'; https://en.wikipedia.org/wiki/Deflate I am using Delphi 11 Enterprise B

    delphimvcframework global variable

    This is my result from test.. and it seems to work.. unit HseqDmDictU; interface uses System.SysUtils, System.Classes, Generics.collections; type TDataModuleDict = class(TDataModule) private FString_Dict: TDictionary<string, String>; Fstring_Dict_Sync: TMultiReadExclusiveWriteSynchronizer; procedure SetString_Dict(const Value: TDictionary<string, String>); procedure Setstring_Dict_Sync( const Value: TMultiReadExclusiveWriteSynchronizer); { Private declarations } public { Public declarations } destructor Destroy; override; procedure initDict; property String_Dict : TDictionary<string,String > read FString_Dict write SetString_Dict; property string_Dict_Sync : TMultiReadExclusiveWriteSynchronizer read Fstring_Dict_Sync write Setstring_Dict_Sync; end; var DataModuleDict: TDataModuleDict; implementation {%CLASSGROUP 'System.Classes.TPersistent'} {$R *.dfm} { TDataModuleDict } procedure TDataModuleDict.initDict; begin FString_Dict := TDictionary<string,String >.create ; Fstring_Dict_Sync := TMultiReadExclusiveWriteSynchronizer.Create; end; destructor TDataModuleDict.Destroy; begin FString_Dict.Free; Fstring_Dict_Sync.Free; inherited; end; procedure TDataModuleDict.SetString_Dict( const Value: TDictionary<string, String>); begin FString_Dict := Value; end; procedure TDataModuleDict.Setstring_Dict_Sync( const Value: TMultiReadExclusiveWriteSynchronizer); begin Fstring_Dict_Sync := Value; end; end. On my console app startup init the Datamodule (not sure for Linux where I will put it, but will try later) begin ReportMemoryLeaksOnShutdown := True; IsMultiThread := True; // Prepare Dict DataModuleDict:= TDataModuleDict.Create(nil); try DataModuleDict.initDict; // Important try if WebRequestHandler <> nil then WebRequestHandler.WebModuleClass := WebModuleClass; WebRequestHandlerProc.MaxConnections := 1024; RunServer(8080); except on E: Exception do Writeln(E.ClassName, ': ', E.Message); end; finally DataModuleDict.Free; end; end. Using dict in code from seperate unit unit DictU; interface uses system.sysutils , system.classes ,DataConU, Generics.collections , TemplateRecordU; type TDictClassV2 = Class ( Tobject ) private public procedure saveString ( akey , avalue : String ) ; function loadString ( akey : String ) :String; End; implementation uses HseqDmDictU; { TDictClassV2 } function TDictClassV2.loadString(akey: String): String; begin result:=''; DataModuleDict.string_Dict_Sync.BeginRead; try DataModuleDict.string_Dict.TryGetValue(akey,result); finally DataModuleDict.string_Dict_Sync.EndRead; end; end; procedure TDictClassV2.saveString(akey, avalue: String); begin DataModuleDict.string_Dict_Sync.BeginWrite; try try if not DataModuleDict.String_Dict.ContainsKey(akey) then DataModuleDict.String_Dict.Add(akey,avalue); Except on E : Exception do begin // logg error end; end; finally DataModuleDict.string_Dict_Sync.EndWrite; end; end; end. If you would do it differently please let me know Thanks again...

    delphimvcframework global variable

    Thanks, I can create it in a datamodule, but I still do not understand howto get this datamodule all the way down to the controller.. FMVC.AddController(TCustomersController); Tcustomercontroller is a class created on request ,and the dict is created at startup. I undestand that I can use/create a datamodule in the controller, but not howto use one created at startup, holding all the data,, normally I would send the dict to my class using a variable. procedure TMyController.GetCustomers ; var lCustomersModule : TMyDataModule ; begin lCustomersModule := TMyDataModule . Create ( nil ) ; try lCustomersModule . QryCustomers . Open () ; again thanks I will also try a few options myself...
  12. Hi , I have downloaded the delphimvcframework and it look’s great 🙂 thanks to @Daniele Teti , I have also bought the book 🙂 great reading, recommended. I love this system , but will play more with it next couple of weeks. A small question. We have a small webbroker app today running on Apache AWS, we use a globale Dict as a keystore in all requests, and we use FMX data pooling. FMX data pooling seems to be well documented in your book, and I guess I can almost use like before. If you look at below code we use dict String_Dict as a global variable handled by TMultiReadExclusiveWriteSynchronizer, any suggestion where to put his variable in delphimvcframework to be able to use it in the different controller / actions like FMVC.AddController(TCustomersController); In our webmodule we have a global variable and we use it with TMultiReadExclusiveWriteSynchronizer from system.sysutil Example data from from our Webmodule … public { Public declarations } SettingTemplateClass : TSettingTemplateClass; end: var WebModuleClass: TComponentClass = TWebModule1; String_Dict : TDictionary<string,String > ; string_Dict_Sync : TMultiReadExclusiveWriteSynchronizer; ….. // connecting String_Dict to a setting class unique for each request procedure TWebModule1.WebModuleCreate(Sender: TObject); begin SettingTemplateClass := TSettingTemplateClass.Create SettingTemplateClass.string_Dict_Sync := string_Dict_Sync; SettingTemplateClass.String_Dict := String_Dict; …. end; // a typical request sending string_dict further using settingTemplateClass to the class generating the response via usersession class procedure TWebModule1.WebModule1getlogondataAction(Sender: TObject; Request: TWebRequest; Response: TWebResponse; var Handled: Boolean); var userSession : TuserSession; ssoInternalClass : TssoInternalClass; companyid : Integer; lsession_data : String; begin companyid := strtointdef( getRequestParamValue (Request , 'companyid' ),0); userSession := TuserSession.create(SettingTemplateClass,getRequestParamValue(request,'token')); try if isSessionValid(Response,userSession) then begin lsession_data :=getRequestParamValue (Request , 'session_data' ); userSession.userSessionData.setSessionData(lsession_data); ssoInternalClass := TssoInternalClass.Create(userSession); try Response.content := ssoInternalClass.getLogonData( companyid ); finally ssoInternalClass.Free; end; end; finally userSession.Free; end; end; ………… initialization String_Dict := TDictionary<string,String >.create ; string_Dict_Sync := TMultiReadExclusiveWriteSynchronizer.Create; finalization String_Dict.Free; string_Dict_Sync.Free; Example using string_dict in class generating the response data below . string_Dict_Sync.BeginRead; try string_Dict.TryGetValue('severDayNumberString', severDayNumberString ); finally string_Dict_Sync.EndRead; end; It it possible o do something similar with delphimvcframework, ? For me it seems like difficult to share data to a controller .. Thanks in advance
  13. Thanks I will increase it
  14. Hi, we are using delphi webbroker backend as backend running on Apache docker AWS ECS Been running smoothly for long time I read this article today https://community.embarcadero.com/blogs/entry/optimize-your-isapi-dlls--increase-maxconnections-1612 In my server I have ThreadsPerChild 50 in mpm_event_module ServerLimit 4 MaxRequestWorkers 200 ThreadsPerChild 50 From my understanding in this article I should increase Application.MaxConnections to 50 like below Web.ApacheApp.InitApplication(@GModuleData); Application.Initialize; Application.MaxConnections:=50; Application.WebModuleClass := WebModuleClass; Application.Run; Is this correct understood, I have never had an error for this, but my understanding is that this number is 32 today and can raise an error ?? Bernt
  15. Thanks for the Idea, and we are considering this. But we have some consideration. Our Delphi app is an API server , ISAPI webbroker module running on Apache linux docker several container instances behind a load balancer. We can share a dictionary between the threads using DataSync := TMultiReadExclusiveWriteSynchronizer.Create; We use MPM_event on apache with this setup per production server <IfDefine TSprod> ServerLimit 8 MaxRequestWorkers 200 ThreadsPerChild 25 </IfDefine> And for setup above this will give 8 dictionary per server holding almost the same information, and 25 threads will share same dictionary this will be super fast but consume more memory than memcache. We could consider reducing ServerLimit and increase ThreadsPerChild for this setup to not use so much memory per server this will increase threads using same dict. We will test a little more on this.
