[fpc-pascal] Network compression

[Dimitrios Chr. Ioannidis via fpc-pascal]

Hi,

  I need to transfer data which are relative big ( 1,2 GB )using low 
memory ( 512MB, 1GB RAM ) machines.


  I was thinking something like load partial the file I ie.e a 64K 
memory block ) compress it send that compressed block via network and at 
the other end receive that block decompressed it and write it to disk, 
"repeat until done" .


  I've searched but I didn't find any example on how to compress / 
decompress in blocks .


  Any hints ?

regards,

Take a look at how it is done in tiOPF. The unit is pretty stand-alone, 
so you don’t need to use the rest of tiOPF to make use of this unit.



https://sourceforge.net/p/tiopf/code/ci/tiopf2/tree/Options/tiCompressZLib.pas

The code should be self explanatory. There is even a tiCompressNone.pas 
which is great for testing purposes.


If you still don’t know how to use the unit, take a look at the unit 
tests, in the “UnitTests” directory, for detailed usage examples.

  Graeme

I need to call an EXE in client site. For example: digital signature.
The client would use his token to sign a document (locally) and then
send to the Web app.

That's why Model-View-Controller is such a great design pattern. If
you use MVC you can simply create a new View component and keep the
Model and Controller without changes.

You can use fcl-web to write the web server:
http://wiki.lazarus.freepascal.org/fcl-web

You will need to rewrite the GUI in html/javascript which is served to
the web browser.

In the past there was stuff like ActiveX and a Java similar, but
nowadays they are pretty much all deprecated sometimes even
unsupported at all, people should use html+javascript for web
interfaces.

In this case I have no idea how it is done. But it can be done, I know
that Banco Itau does this, but I don't know what exactly they use.

I've been written Web applications using fcl-web for a while... this
isn't my problem.

I can't. For security reasons I need to have an app installed on client.
Did you see my email before, about digital signature? That is one of
these features...

ActiveX works but as you said, all these are deprecated...

I will take a look on NativeMessaging:
https://developer.chrome.com/extensions/nativeMessaging

Another option, that I thought, is make an app that is a local web
server after the user has installed.
The web real app could make requests to http//localhost and have a
communication between them.

This idea. I think Banco do Brasil does this too.
Maybe if I develop an Extension for the browser (I need Chrome and IE)
would be simpler but I don't know how to do this yet.

Here is a simple sample program that has the issue for me on both my windows 10 
desktop and my windows 10 laptop, both are 64bit.
https://hastebin.com/nubonozaho.pas

I started thinking about this, and did some more tests, and I think I have 
narrowed down what is really happening, but not sure how to fix it.

The problem is not the ALT-tab from the graphics window,  it's ALT being 
pressed when the window focus changes.   CTRL is also affected, but not shift.  
Try this:
Go to Graph window,  type some letters,  see that it's working correctly,  now 
hold just ALT, or CTRL - switch to another window by clicking on it.  Click on 
console window, see letters are working correctly, now go back to graph window, 
 anything you press acts like ALT, or CTRL is still being pressed until you 
actually enter a keystroke using ALT, or CTRL.   It seems to me there is 
probably some flag or variable being set that the alt or ctrl key is being 
pressed, but is being interrupted by the window focus change, when focus is 
brought back, the variable is still set for ALT or CTRL being down, but neither 
is down anymore, but the flag cannot be cleared until a key sequence using ctrl 
or alt is used.  I did also notice that just hitting alt or ctrl and releasing 
it in the graph window clears the condition and characters are back to normal 
again.

this is really sounding like a problem i remember from early GUIs several 
decades ago... when switching tasks, the state of the CTRL or ALT or SHIFT keys 
would ""get stuck""... when returning, things weren't right but tapping the 
CTRL, ALT and/or SHIFT keys a few times would return them to their proper state...


i remember the problem but am not aware of the fix... i know i dealt with it on 
OS/2 as well as winwhatever... we just got into the habit of tapping those keys 
when we returned...

Just like you now use -FuSomePath to tell the compiler where to find
units, you can use -FiSomePath to tell the compiler where to look for
include files.

See `fpc -h`, under the section "-F Set file names and paths:" for a
list of other related switches.

I have done the "download snapshot" but I just don't know what to do with it 
now to properly integrate it into my compiler.  

Here is what I have tried to do.
First I moved everything from J:\Programming\FPC 3.0.2\units\i386-win32\graph 
to a temporary location so it wouldn't find the old versions of ptcgraph and 
ptccrt
Now when I try to compile my program, I get unit ptcgraph not found... which is 
what I want because I want to be sure not to get the old version
Then I copied the entire snapshot to into J:\Programming\FPC 
3.0.2\units\i386-win32\ptcpas
Now when I try to compile my program, I still get unit ptcgraph not found.
I added J:\Programming\FPC 3.0.2\units\$fpctarget\ptcpas\* to the directories
Now I got an error that it could not find graphh.inc 
So I copied all the .inc files from J:\Programming\FPC 
3.0.2\units\i386-win32\graph\inc to J:\Programming\FPC 
3.0.2\units\i386-win32\graph because I have no idea how else to make it find 
them.
Now I can can compile successfully and run my program, but it has the same 
issues.
But I notice the modified file win32kbd.inc is never used.   I have even 
removed it temporarily and I can still compile successfully.  I did a 
search for win32kbd and I find win32kbdd.inc but not win32kbd.inc

That is where I am at.  I think If I could correctly apply win32kbd.inc it may 
work

Here is a simple sample program that has the issue for me on both my windows 10 
desktop and my windows 10 laptop, both are 64bit.
https://hastebin.com/nubonozaho.pas

I started thinking about this, and did some more tests, and I think I have 
narrowed down what is really happening, but not sure how to fix it.

The problem is not the ALT-tab from the graphics window,  it's ALT being 
pressed when the window focus changes.   CTRL is also affected, but not shift.  
Try this:
Go to Graph window,  type some letters,  see that it's working correctly,  now 
hold just ALT, or CTRL - switch to another window by clicking on it.  Click on 
console window, see letters are working correctly, now go back to graph window, 
 anything you press acts like ALT, or CTRL is still being pressed until you 
actually enter a keystroke using ALT, or CTRL.   It seems to me there is 
probably some flag or variable being set that the alt or ctrl key is being 
pressed, but is being interrupted by the window focus change, when focus is 
brought back, the variable is still set for ALT or CTRL being down, but neither 
is down anymore, but the flag cannot be cleared until a key sequence using ctrl 
or alt is used.  I did also notice that just hitting alt or ctrl and releasing 
it in the graph window clears the condition and characters are back to normal 
again.

>Just like you now use -FuSomePath to tell the compiler where to find units, 
>you can use -FiSomePath to tell the compiler where to look for include files.

I've been trying to compile with Free Pascal Text IDE, I have no experience 
with compiling programs from the command line,  but this gave me an idea to try 
it from command line instead.

First, I thought I would start clean, and  I re-installed Free Pascal and left 
the directory structure alone, and just changed the drive to H: where I have a 
lot of room. I suspect it did not like the space I had in my directory name.
From the new install of FPC 3.0.2 on my H Drive, I was able to successfully 
follow the instructions and I finally managed to compile ptcpas-code-715-trunk.

I was also able to compile the examples and they executed correctly.  So I used 
the command line used to compile one of the examples, and put the whole path of 
ptcpas in and I was finally able to successfully compile my test program with 
the following command line:
h:/FPC/3.0.2/bin/i386-Win32/ppc386.exe 
-Fuh:/ptcpas-code-715-trunk/units/i386-win32/ -FE. 
-FUh:/ptcpas-code-715-trunk/units/i386-win32 -di386 dual-key-screen.pas
When I compiled It this way, I am now able to ALT-Tab from the graph window and 
when I return everything is fine,  so this proves the problem has been solved, 
but integrating the solution into my compiler is the problem.

I am trying to get it to work from the Free Pascal text mode IDE
but when I add h:\ptcpas-code-715-trunk\units\i386-win32 to the list of unit 
directories in the Free Pascal text IDE and try to compile my program, I get:

PPU Loading H:\ptcpas-code-715-trunk\units\i386-win32\ptcgraph.ppu

How do I properly use the FreePascal Text mode IDE to use the ptcpas units I 
compiled?

My entries under directories > Units are:
H:\ptcpas-code-715-trunk\units\i386-win32

Just like you now use -FuSomePath to tell the compiler where to find units, you 
can use -FiSomePath to tell the compiler where to look for include files.

See `fpc -h`, under the section "-F Set file names and paths:" for a list of 
other related switches.

I understand these security reasons and I agree, of course...
But this Exe that I am talking about should be installed for all
machines that want use the system so, won't be a problem for security.



Well there is always XUL Runner (Firefox embedded) or Chromium Embedded, 
to run a local browser on the computer machine that is just like

I'm still thinking on these options:

1. NativeMessaging:
https://developer.chrome.com/extensions/nativeMessaging

2. to make an app that will be a local web server, after the user has 
installed.

The web real app could make requests to http//localhost and have a
communication between them.


Or a local chromium embedded/firefox embedded web browser that can talk 
to any native code you want, then the person does not need a web server 
running but will have to install the chromium embedded CEF dll's

I understand these security reasons and I agree, of course...
But this Exe that I am talking about should be installed for all
machines that want use the system so, won't be a problem for security.

Unfortunatelly I think either Chrome doesn't use it or there are some
restrictions... and they can cut off — if still working — in the
future, I don't know.
I would like to use something simpler, that doesn't depends of
Microsoft's stuff.

[fpc-pascal] OpenGL and SDL frustrations

[Ryan Joseph]

I’ve wasted so much time on this I just need to stop and ask for help already. 
Over the last few years I’ve been picking away at OpenGL and only ever got the 
legacy 2.x API to work which has been fine for making 2D games but I wanted to 
at least learn the modern API and shaders.

Here’s a snippet I cobbled together from a test program. It merely wants to 
draw a triangle. The actual OpenGL is from a tutorial and I don’t see how 
anything could be simpler than this. The only thing curious to me is why I 
can’t load the version of OpenGL I want from SDL. If I attempt to load 4.0 
(with SDL_GL_SetAttribute) GL_VERSION returns null but if I load 3.3 it works 
and GL_VERSION returns 4.1 anyways (I’m a Mac from 2015).

I removed the error handling code here but I don’t get any errors, just a black 
screen. Despite the tutorial I was following not using a shader they still got 
a white triangle (I added a shader also but it still didn’t work so I removed 
it to reduce complexity). The only thing I can think of is they were using GLEW 
and it did some init that SDL isn’t doing but I doubt it. This is barebones 
simple OpenGL here.

Any ideas on what’s wrong with this? I don’t care about this example in 
particular I just want to draw ANYTHING using OpenGL 3.3 so I can move forward.

=

type
TVec2 = record
x, y: GLfloat;
end;

var
verts: array[0..2] of TVec2;
bufferID: GLuint;   
vao: GLuint;

// run sdl window
if SDL_Init(SDL_INIT_VIDEO) < 0 then
Fatal('SDL could not initialize! '+SDL_GetError);

// load function pointers
if Load_GL_VERSION_3_3 = false then
Fatal('OpenGL is not loaded');

SDL_GL_SetAttribute(SDL_GL_CONTEXT_PROFILE_MASK, SDL_GL_CONTEXT_PROFILE_CORE);
// NOTE: 4.0 doesn't work, GL_VERSION return null
SDL_GL_SetAttribute(SDL_GL_CONTEXT_MAJOR_VERSION, 3);
SDL_GL_SetAttribute(SDL_GL_CONTEXT_MINOR_VERSION, 3);   
SDL_GL_SetAttribute(SDL_GL_DOUBLEBUFFER, 1);
SDL_GL_SetAttribute(SDL_GL_DEPTH_SIZE, 16);

// create window
window := SDL_CreateWindow('SDL Tutorial', SDL_WINDOWPOS_UNDEFINED, 
SDL_WINDOWPOS_UNDEFINED, width, height, SDL_WINDOW_SHOWN + SDL_WINDOW_OPENGL);
context := SDL_GL_CreateContext(window);
SDL_GL_MakeCurrent(window, context);
SDL_GL_SetSwapInterval(1);

writeln('Vendor: ', glGetString(GL_VENDOR));
writeln('OpenGL Version: ', glGetString(GL_VERSION));
writeln('GLSL Version: ', glGetString(GL_SHADING_LANGUAGE_VERSION));

// NOTE: despite SDL_GL_SetAttribute asking for 3.3 and 4.0 failing GL_VERSION 
still returns 4.1
// Vendor: Intel Inc.
// OpenGL Version: 4.1 INTEL-10.25.13
// GLSL Version: 4.10 

// setup
glViewPort(0, 0, width, height);

// simplest example possible
// https://www.youtube.com/watch?v=Dyue3MzJDss
verts[0].x := 0.0;
verts[0].y := 1.0; 
verts[1].x := -1.0;
verts[1].y := -1.0; 
verts[2].x := 1.0;
verts[2].y := -1.0;

// NOTE: glEnableVertexAttribArray returns an error if I don't bind a vao
glGenVertexArrays(1, @vao);
glBindVertexArray(vao);

// gen array buffer and bind to verts
glGenBuffers(1, @bufferID);
glBindBuffer(GL_ARRAY_BUFFER, bufferID);
glBufferData(GL_ARRAY_BUFFER, sizeof(verts), @verts, GL_STATIC_DRAW);
glEnableVertexAttribArray(0);
glVertexAttribPointer(0, 2, GL_FLOAT, GL_FALSE, sizeof(TVec2), nil);

// draw loop
glClearColor(0, 0, 0, 1);
glClear(GL_COLOR_BUFFER_BIT);
glDrawArrays(GL_TRIANGLES, 0, 3);
SDL_GL_SwapWindow(window);
...

Re: [fpc-pascal] Browser and exe

[leledumbo via fpc-pascal]

> Is there a way to call an Exe (previously installed, no problem with that)
to interact with an Exe, working in IE and Chrome?

Not from client side AFAIK. You'll need to create a local server side app,
let that one executes the exe and response back to the client (if needed).
