    Thanks for having a look.

    I did not find the "raw string", that's why I copied what a regular mail client (emClient) presented as source code of the mail, when I used it to receive the mail. (emClient could decode the file name). It looks exactly like it's shown in the forum. quotes and question marks included.

    I did not know about PartName/PartNameW, I will check this, but sadly earliest on wednesday. I will also try to extract the string name from the raw MessageLine.

    Hi,

     

    we run into the problem, that when receiving mails some attachments don't show up. We use SslPop3Client.OnMessageLine to read all line, add them to a TStringlist, put that into a memoryStream and then do mimeDecode.DecodeStreamEx(mailStream). This works, except for one customer. Analysing the "raw" mail, I can see that the name for the attachment part is encoded.

    If there is "clear text" in the name part it works, with this encoded text it doesn't work. Do you have any idea what's going wrong?

    4) Now back to (1) of DELETE, the same paragraph as GET and HEAD but we have specified error to return in case of absence of the content, in other words it is likely that there is generally defined semantics for DELETE (between client and server) hence the request content is needed.

    Nope, 204 is about the response (and 2xx is always success!) not having content. https://www.rfc-editor.org/rfc/rfc9110.html#status.204

     

    Of course you can have an API that uses a content payload with DELETE, especially if you have control over the server and the client, but according to the RFC ICS is not obliged to support this out of the box.

    So effectively supporting a public ClientId requires the ClientSecret to be specified before GetToken, GrantAuthToken, etc?  Have you tried changing ClientSecret immediately before these methods?  I'm not doing any development for a few days, busy with something else.

    No, a public client doesn't have a ClientSecret. Only an ID and is created in Azure Entra ID (formerly know as Azure Active Directory) as Multiple organizations type

    image.thumb.png.ad132161d333b55ef78302efef9b5700.png

    Like I said, just commenting out the checks if there is a secret and submitting and setting an empty one seems to work. But I'm not deep enough in the component or the OAuth flow to know if something else breaks. It was too late to do further tests. I guess I will know next week.
    Take your time, but it would be nice, if you could take a look, when you are back at developing, so we don't have to patch ISC on our end.
    If we gather further information I will post here.

    Sorry, no quick answer, a public client seems the opposite of the OAuth2 concepts.  My Azure credentials are currently expired or dead, so no recent testing, but I'll look into this next week.

    If you want to read more: https://learn.microsoft.com/en-us/entra/identity-platform/msal-client-applications

     

    But I think it should be enough to know that there are client types, that are only identified by ID but must not send a secret.
    The user of course still has to enter his credentials into the browser to authenticate, the client sends his ID, so the auth website can show "You are trying to give App XYZ access". Of course that's easy to impersonate, but that's what signed executables are for...
    It's all horribly complicated.

    We are currently redoing our mail module using ICS because Clever Internet Suite seems to be gone for good and The Office 365 sync components we used got bought out and rolled into a completely different solution.
    But because our software is a commercial business software that gets used by various end users I registered a "public client" (for "Multiple Organizations") for usage with the "Real O365 Mail for companies and schools", not personal accounts.

     

    But the ICS components need a Client_Secret (there are hardcoded checks) but if you send one, you won't get a token: 

    {"error":"invalid_client","error_description":"AADSTS700025: Client is public so neither 'client_assertion' nor 'client_secret' should be presented. Trace ID: 4b38379d-3e12-485c-aff2-e0f450495800 Correlation ID: ad9abfcf-dac7-461f-a58d-b73136e07ae2 Timestamp: 2025-03-27 20:24:31Z","error_codes":[700025],"timestamp":"2025-03-27 20:24:31Z","trace_id":"4b38379d-3e12-485c-aff2-e0f450495800","correlation_id":"ad9abfcf-dac7-461f-a58d-b73136e07ae2"}


    I patched out the check of 

    if (FClientId = '') or (FClientSecret = '') then begin

    it seems I got a valid token, but I'm not sure what else broke, because there definitely seems to be code that still attempts to send an empty client_secret with requests.

    Are'nt these just several independent server layers between the client and the LLMs, to unify the LLM communications?

    That's exactly what it is for. Unified way of discovery and access.

    Currently they talk only about Claude, it seems very Claude centric to me.

    Anthropic wrote the spec but others, like Cursor adapted it. It's becoming some sort of standard way of tool and content discovery and access.

    Do these MCP servers have any REST API or whatsoever, maybe I have overseen this?

    It's a JSON RPC 2.0 API.

    2 hours ago, Rollo62 said:

    For the use of agents, wouldn't it make more or same sense to have these features built in the client SDK ( Delphi Code ) in the first place?

    Then your app would have local, full control over all LLM's and DB's.

    If I want to integrate an agent into my software, I could do that.

    But I want to implemented several things: a) a way for any Agent to interact with (aspects of) my software. b) a MCP Server for the DBMS we use so I can use the (meta) information during development using agents or Cursor.

    2 hours ago, Rollo62 said:

    I would start with unifying access to different LLMs by implementing a general Delphi Interface for several LLM implementations,
    to have a compatible interface between several LLM ( if that will be really possible ).

    This has nothing to do with MCPs, but most cloud systems use a REST API that's similar to OpenAI's. So no need for that.

    To use local LLMs there are a few competing approaches possible, but you can leave the heavy lifting to libraries like llama.cpp or even use something like ollama and just use this API.

    You are not using a debug version of the application because there is missing details in the stack trace. Make sure you rebuild all, including the components.the debugger should show the excat line where the exception occurs.

    The line is already mentioned in the exception message in my first post. But next time I will pay special attention to this detail.

    Bug now fixed, it was a late change in V9.,4 flushing the log file to disk in case the request failed, but not actually checking the log was opened.

    So it was exactly what I hoped for. 😉

    How do you propose I reproduce that problem?  It is most likely something specific to your installation.  

    I hoped it's just something like "Oh, I tried it and it happens on my end too, seems I overlooked xyz". There is nothing special, I think.

    Edit; thinking back, it might be first time issue saving INI settings or something, Is it repeatable?

    It happens very time.

    To be able to debug a problem where one of my users can't reach some URLs (get's 404 despite beeing able to access the URLs in the browser on the same machine) I tried to compile OverbyteIcsHttpRestTst.dproj for him to see if the same error happens with this "reference implementation".

     

    But when I click "Start REST Request" I always get the same Access Violation:

    Quote

    ThreadId=9672
    ProcessId=6
    ThreadName=""
    ExceptionMessage="Access violation at address 0000000000866164. Read of address 00000000000000E8"

    ExceptionDisplayName="$C0000005"
    ExceptionAddress=00866164
    FileName="C:\lisa\bib\ics\Source\OverbyteIcsSslUtils.pas"
    LineNumber=1145

    It doesn't matter if Release or Debug Build or 32 or 64 Bit. It just never works.

    I use Delphi 11.2 if that matters.

    I make heavy use of 'TSslHttpRest' for all kinds of requests, but with the recent update to ICS 9.4 (I skipped 9.3) some requests to plain text endpoints fail. I get 200 OK, but the responseraw is empty.

    I think the culprit is this: 

    { V9.3 is a MIME type texual or printable text }
function IcsMimeIsTextual(const MimeType: String): Boolean;
begin
    Result := (Pos ('text/', MimeType) = 1) or (Pos ('json', MimeType) > 0)  or
               (Pos ('javascript', MimeType) > 0) or (Pos ('xml', MimeType) > 0);
end;

    I have to request some servers that answer with content-type 'text' instead of 'text/plain', so this function doesn't work for me.

    I'm not sure if you consider this a bug, because I think just 'text' is no "official" mime-type, but on the other hand, I have no control over the servers I have to query, so I would appreciate if there was a solution besides me manually patching the ICS code.

    Do you mean you are using Caddy or nginx as a proxy in front of non-SSL ICS servers?

    Yes. It's not only reverse-proxing ICS based servers/APIs, but also other processes and serving static files. Everything in one place. I can imagine others working like this as well. In my case Caddy handles the certificates (via ZeroSSL) automagically.

    Not sure how many ICS users actually make use of Let's Encrypt certificates, I never hear about bugs or problems, so perhaps they just work, or ICS users are still paying for commercial certificates?

    I'm having Caddy in front of everything. Our customers either use Caddy or nginx.

    What are nowadays best internet components (stable and reliable) http, POST, GET, PUT, PATCH etc (REST Delphi built-in not an option)

    I use ICS for most stuff. The little complaints I have usually get addressed fast.

    I still enjoying trying out the components and have some first ideas but not enough time.

    But I have a few questions: 

    • The Demos seem to be a bit messed up pathwise. Difficult to describe, I think it's best if you do a clean install and open a Demo in Delphi yourself and then start it from within Delphi.
    • You have SaveSVG and ExportDoc procedures. Both save to files. Is there a reason there is no option to save to a stream to continue processing the generated label directly in a program? Or am I overlooking something?
    • I managed to hide almost all control elements of the editor component. But not the scrollbars. Am I overlooking something?
    • I see that you can use a CSV file or JSON as Data Source. But is it also possible to use a TDataSet?
