A mormot2 daemon does not follow the configuration after an update. I using an inherited class from TSynDaemonSettings with extra properties in the published section and the config file is an INI file.
The same source compiled with Delphi it works ok, but with FPC all boolean directives are taking all the false value. I do not know from which version of Mormot it started to happen.
My FPC version is Lazarus 2.2.4 (rev lazarus_2_2_4-0-g06a78ed923) FPC 3.2.2 x86_64-win64-win32/win64 and even with last versions it is the same.
I tried for the first time the debugger from FPC and I found that the problem should be in line 4243 from mormot.core.data, "if p^.Prop^.SetValueText(Instance, v) then" but even with O0 optimization the debugger shows only assembly when calling this function and it is impossible for me to follow.
string and integers work without problem

Any ideas? Thank you in advance

You had right, I tried to find out what caused this error and I found it:
I had a THttpClientSocket object with an unauthorized interface service to create a JWT when needed without destroying and recreating the service interface. If more than 65 secs passed without using it and a request is done after that, using it, the above exception is created.

I am using a TRestHttpClientWinHttp to call inteface services in a  Mormot2 server and I am not using sessions.
As far as I can understand, Mormot2 does not support JWT by internal design.  There is no TRestClientAuthentication for JWTs.
In the server, I am checking if JWT header exists and if it is valid in each interface call

In the client, is it possible to use OnAuthentificationFailed event to refresh the expired JWT that the client should send in each interface call?

If I implement a timer based renew function running in the background, how can I protect the client from accessing the SessionHttpHeader during the timeframe it is set by the renew function?

Is there an OnCall event that runs before a service inteface call is made by a TRestHttpClientWinHttp ? I noticed that SessionHttpHeader is added to headers once before the loop of OnAuthentificationFailed

#17 Re: mORMot Framework » Stopping a mormot2 server for update » 2022-10-30 15:19:32

The service daemon with the last updates works perfectly. I noticed that if you just run from the command line the service executable without options I can log an exception from the windows' Tservice but it is harmless.

Another point that needs to be handled better in windows is the platform independent commands in mormot.core.os to run an executable from a mormot server (RunProcess, RunCommand, etc)

In my scenario, the service periodically looks for updates. If it finds an available update, it downloads it and runs an other executable to do the update, the ServiceUpdater.
I have created this executable, the ServiceUpdater, using mormot framework that stops the service, unzips and replaces the executable and re-runs the service.
This executable does not work, if the services runs it. It waits for the service to stop till timeout.
Looking the code, I noticed that all mormot's commands from windows are based on Createprocess where the host process can not end before the executed process

I change the mormot's RunProcess/RunCommand to ShellExecute with command 'open' and now the service stops and the ServiceUpdater can continue to do the update.
Probably it could be included for windows. I will test this situation also in linux.

that's how you're supposed to use it.  The only reason you can still call Add/Update/Delete directly from the TRestServerDB instance is because it's there for backwards compatibility with mORMot 1. If you define PUREMORMOT2 flag for your project then you will see those direct methods no longer available.

Thank you for response. I apologize, I am not sure I understand the response
Do you mean that I should use a TrestClientDB.Create(aRunningServer: TRestServerDB) ?

Replies: 4

Looking an example from mormot2 I noticed that for standalone applications it exists also TRestClientDB that can be created to connect to external databases also through SQLITE.
I noticed that TrestClientDB can be created also with the following contructor:

    /// initialize the class, for an existing TRestServerDB
    // - the client TOrmModel will be cloned from the server's one
    // - the TRestServerDB and TSqlDatabase instances won't be managed by the
    // client, but will access directly to the server
    constructor Create(aRunningServer: TRestServerDB); reintroduce; overload;

Having all past problems with multiple threads trying to add to a database new records or updating others I am wondering:
When having multiple threads to use a TRestServerDB instance for the same tables, is it better to use TRestServerDB's orm interface directly ?
Or use one TrestClientDB instance for each thread with the above constructor called with the same TrestServerDB instance ?
What are the pros/cons?
Thank you in advance

PS I can not find the TSQLRestClientRedirect somewhere. Is it implemented?

Note: To help better understand my case:
I have clients that call a rest interface procedure but for a work that will take time and requests info from other API servers too. So the REST request is finished and the job is entered in a TSynThreadPool. So, later a thread will have to do all database work to provide the response through websockets. So, the above discussion is about threads running from a TSynThreadPool and accessing a main-central TRestServerDB instance.
I believe that a REST interface procedure in a server called by a client will not have problems to access a main-central TRestServerDB instance to do database work

We have a windows service that runs a second executable that it is the real mormot2 server
The service has the responsibility to automatically update the mormot2 server executable when an update by the developer is available.
What will be a reliable way to update it?
We want to stop receiving new requests till the existing are served and closed, to terminate the server and the mormot2 server executable and to update the executable and restart it.
Killing the windows process is not a solution as I think. What do you propose?
Creating a rest function to request to finish? And if mormot2 is in dead-lock situation? And how do you find that a mormot2 server windows process is exited? By trying to delete or to modify the mormot2 executable as file?

In linux, we have the systemd for a number of linux distos
Do you run mormot2 server executable as a process controlled by systemd (to rely to databases being ready for example) or by eg rc.local?
How do you start it? Using -f or -r switch in TsynDaemon?
How do you stop it? Using SIGSTOP?
Again how is it better to look for updates and auto-update?
Do you run (and how do you initiate it) an other script to stop systemd service, update and restart it?

Let's consider that the update host and procedure to receive the updated version is safe discussing about security considerations

And PostgreSQL also expect a complex syntax with the column names to ignore, as On CONFLICT(column1, ....) DO NOTHING;.

Firebird,  Oracle, Postgres do not have an 'INSERT [OR] IGNORE' dialect

For Oracle I have included the info

For firebird >2.1 is just a little more complex (you have to provide the unique indexes) as described here:

#37 Re: mORMot Framework » memberexists does not help » 2022-10-21 07:35:28

Reading the following response from overflow:

REPLACE INTO table(column_list) VALUES(value_list);

is a shorter form of

INSERT OR REPLACE INTO table(column_list) VALUES(value_list);

For REPLACE to execute correctly your table structure must have unique rows, whether a simple primary key or a unique index.

REPLACE deletes, then INSERTs the record and will cause an INSERT Trigger to execute if you have them setup. If you have a trigger on INSERT, you may encounter issues.

This is a work around.. not checked the speed..

INSERT OR IGNORE INTO table (column_list) VALUES(value_list);

followed by

UPDATE table SET field=value,field2=value WHERE uniqueid='uniquevalue'

This method allows a replace to occur without causing a trigger.

Probably an insertOrIgnore (or an extra boolean flag in add to add 'or ignore') is better for this case and it is supported by sqlite
