Project 29 - SmartMobileStudio Client

warleyalex · 2014-07-10 19:37:00

SMart 2.1.0 beta 2
Delphi 7
---------------------------------------
Project 27 - CrossPlatform Clients folder
---------------------------------------
In order to test SmartMS project, you have to run the RegressionTestsServer.dpr.

I have to comment some lines:

unit PeopleServer;
//mORMotWrappers,

In RegressionTests I added this:

program RegressionTests;
line 51 // StopServer;
line 77 StopServer;

---------------------------------------
Project 29 - SmartMobileStudio Client

When I connect: 873 requests are performed and 26 errors (400 status code).

It is important to inform you that SMSC.EXE (command-line compiler) is made free to the community. I think you can compile .PAS to .JS but I don't find a way.

Errors are OK.

In fact they are part of the tests, and mean that a deleted record has been really deleted.

Where did you get the 2.1 beta?

warleyalex · 2014-07-10 20:52:25

ab · 2014-07-11 08:45:53

Thanks for the links.

The 2.1 beta is a great version.
Internal debugger is a great idea... but I was not able to make it work yet!
I made several support tickets.
Hope they will stabilize the beast!

warleyalex · 2014-08-06 21:00:23

Project29 with Chrome, I always get a bunch of these errors:
----------------------

If result is null, this error has vanished!

ab · 2014-08-06 21:23:46

I did not have issue with chrome.

But I will check tomorrow.
Perhaps the asm is wrong somewhat...

ab · 2014-08-07 06:17:50

On our side, no problem at all with the generated code, using SMS 2.1 beta 3.

Call$19 is a local parameter, so its name depends on the function context, but is consistent AFAIK.

If we enable obfuscation and/or compaction, code still works as expected.

For instance, with obfuscation:

   /// procedure TSMSHttpConnectionClass.URI(var Call: TSQLRestURIParams; const InDataType: String; KeepAlive: Integer)
   ///  [line: 833, column: 35, file: SynCrossPlatformSpecific]
   ,Vc:function(Self, KL, gIV, aK) {
      var aB = {v:0};
      var oQc = {};
      oQc.v = "";
      var VG1 = 0;
      var HZJ = "";
      var k2F = "";
      
    KL.Cv = new XMLHttpRequest();
  if (KL.Av) {
         KL.Cv.onreadystatechange = function () {

Sounds perfectly fine to me.
I honestly do not understand what's wrong on your side.

warleyalex · 2014-08-07 12:47:35

Sounds like the problem is my old Chrome 30.0.1599.101 m

var X1 = {
	$ClassName : "TSMSHttpConnectionClass",
	$Parent : VX,
	$Init : function ($) {
		VX.$Init($)
	},
	QU : function (S, n3, fI, by) {
		var co = {
			v : 0
		};
		var ca = {};
		ca.v = "";
		var zd = 0;
		var wC = "";
		var rjU = "";
		n3.ut = new XMLHttpRequest();
		if (n3.vi) {
			n3.ut.onreadystatechange = function () {

ab · 2014-08-07 16:37:50

I'm using Chrome 36...

warleyalex · 2014-08-08 01:54:18

Firefox doesn’t complain about this, and Chrome only seems to care about this annoying cryptic error message.

Chrome 19:
INVALID_STATE_ERR: DOM Exception 11: An attempt was made to use an object that is not, or is no longer, usable.
index.html:7907

Chrome 30:
Uncaught InvalidStateError: An attempt was made to use an object that is not, or is no longer, usable.
index.html:7907

Chrome 31:
Uncaught InvalidStateError: Failed to execute 'getResponseHeader' on 'XMLHttpRequest': the object's state must not be UNSENT or OPENED. index.html:7907

The getResponseHeader(header) method must run these steps:
If the state is UNSENT or OPENED, return null.
If the error flag is set, return null.
If header is a case-insensitive match for Set-Cookie or Set-Cookie2, return null.
If header is a case-insensitive match for multiple response headers, return the values of these headers as a single concatenated string separated from each other by a U+002C COMMA U+0020 SPACE character pair.
If header is a case-insensitive match for a single response header, return the value of that header.
Return null.

I think the last line is causing this annoying cryptic error. If I comment this line, Chrome 19,30 and 31 + FF, no annoying messages anymore.

{CrossPlatformREST}

procedure TSQLRestClientURI.URI(var Call: TSQLRestURIParams);
var sign: string;
begin
  Call.OutStatus := HTML_UNAVAILABLE;
  Call.OutInternalState := 0;
  if self=nil then
    exit;
  if (fAuthentication<>nil) and (fAuthentication.SessionID<>0) then begin
    if Pos('?',Call.Url)=0 then
      sign := '?session_signature=' else
      sign := '&session_signature=';
    Call.Url := Call.Url+sign+
      fAuthentication.ClientSessionComputeSignature(self,Call.Url);
  end;
  InternalURI(Call);
 // Call.OutInternalState := StrToIntDef(GetOutHeader(Call,'Server-InternalState'),0);
end;

ab · 2014-08-08 10:52:24

So we tried to avoid calling XHR.getResponseHeader() which is broken with some browsers...
See http://synopse.info/fossil/info/3a37921d7928

I hope it will fix your issue.
Performance may be only slightly slower (we optimized the FindHeader() function somewhat).
Profiling (in both IE and Chrome) states that most of the time is spent within HTTP communication, not in our SmartPascal/JavaScript code.

warleyalex · 2014-08-08 18:23:48

Yes! It works perfectly fine now.

igors233 · 2015-11-18 06:42:33

Hi all,

I'm trying to run WebForm.sproj (from this sample) in latest SMS 2.2, but it doesn't compile, it's complaining about missing WebForm.pas.
Is there perhaps an updated sample (same thing with one in latests nightly build)?

Regards,
Igor
