Re: [fpc-pascal] httpdefs.pp multipart/form-data
At the moment, it loads the whole content into a stream for processing line by line. It is possible to create a patch to not do processing (exception, error message, trigger an event handler, etc.) if the ContentLength exceeds a specified size. Leonardo M.

Is it possible to use fclweb without linking LResources and a lazarus

One way is without using modules, select 'File-New-Custom CGI Program'
from the lazarus-menu.
This seems to produce a simple CGI app, not an apache module.
Another way is using the 'normal' web-module, but remove it's
resource-file. So you have to create all components at run-time. To do
that you can simply remove the LResources from the uses-line, and remove
the {$I unit1.lrs} line
And this is the first thing I tried but the module fails miserably with
error:
- *Failed to initialize component: No streaming method available
which makes me think the module is actually looking for a resource,
especially as the module works when i include a stub webmodule resource.

Leonardo M. Ramé I am not sure what the exception problem might be, but you cannot just do a SET command in a command prompt for CGI programs. For CGI programs you need to pass global environment variables with Apache, it is not automatic. For example, in the Apache httpd.conf with a "PassEnv TEMP" or "SetEnv TEMP /pathtotmpdir" line so the web server passes this global environment variable to the CGI programs' local environment variables. Only these "manually" passed ones and the ones Apache sends (the CGI environment variables that are in the CGI standard) are visible from within CGI programs.

[fpc-pascal] fcl-web webdata example(s) on Windows has some problems
Hi,
WinXP 32, FPC and Lazarus latest SVN checkout.
I was trying to play a little bit with the promising new fcl-web webdata
features to see how JSON/EXTJS works with FPC/Lazarus and came up with
the following problems in the first demo example
...fpcdir...\packages\fcl-web\examples\webdata\demo\
1. The project source files in there contains a line something like:
{$IFDEF WINDOWS}{$R somethinghere.rc}{$ENDIF}
This gives an error message during compile in Lazarus that the .rc file
is not found. When commented out, they compile OK.
2. When loading the extgrid-json.html into my browser, the grid comes
up, but only says "No data to display" and the data.xml debug file contains
"{ "success" : false, "message" : "Unknown web data input adaptor name:
\"\"" }"
(the CGI program has access to the users.dbf file, in fact this dbf file
is regenerated every time the html page is loaded)
3. When loading the extgrid-xml.html , there is a popup error message
with the same 'Unknown web data input adaptor name: ""' message. The
data.xml debug file has
"
false
Unknown web data input adaptor name: ""
"
in it.
I could not yet figure out what the problem is due to limited time at
the moment (2:00AM), any suggestions would be welcomed to find the
solution/fix.
Thanks,

(Sorry if this is a little bit lengthy, but I would really like to see this through and have super demo programs for both Linux/Windows people. Also, to learn how to use these new Lazarus/FPC features, of course.) If I can help with some simple works to get this done - other than these testings - , please let me know how. a; fcl-web, fpweb general 1. It would be really nice to have the fpweb action names generated properly (like Delphi) in Lazarus ( http://bugs.freepascal.org/view.php?id=15820 ) 2. The other demo apps (demo2...demo6) also have the .rc file line in the project .lpr source 3. Demos.txt in the ...examples\webdata\ folder mentions Demo1, but the directories go as Demo, Demo2, Demo3 ... 4. The other fpweb dependent demos (ex: fptemplate) were moved into the \lazarus\components\fpweb\demo\ directory from the fpc\packages\fcl-web. Shouldn't we have these demo programs in one place only? 5. Packages "weblaz" and "lazwebextra" in Lazarus (under fpweb directory) should have somewhat similar name and definitely some description. In the Lazarus fpweb directory the file names and package names need to be organized a little bit. I know this is vague... b; demo (...\examples\webdata\demo) 1. Delete button should maybe have a confirmation dialog and to not have to click on Save after clicking on Delete to actually delete a record. 2. minor, nice to have: Maybe autosave after leaving any cell after editing? Bigot Excel/OpenOffice using customers will expect it to work like that. I know this is just a simple demo... 3. Maybe note for Windows people that they probably need to put the CGI program into their cgi-bin directory after compilation, and copy the .dbf file next to it. Then they need to modify the extgrid*.js files and change the extgrid.cgi to something like "http://127.0.0.1:8080/cgi-bin/extgrid.cgi"; or similar (it works with .cgi on Windows with Apache, there is no need to have the .exe extension). Also, to put the .html and .js files into their DocumentRoot directory under folder "demo" or something. Also, to unzip the downloaded extjs zip file into their DocumentRoot (and there will be an ignorable problem in the docs folder somewhere during unzipping, because it seems extjs uses menu.html and Menu.html files in the same directory in one place /v3.2.1/, which Windows does not support). 4. The JSON html is working now, but the xml one doesn't list anything in the grid. This might be that I did something wrong, will check demo2 and try both there. c; demo2 - demo6 1. "The following package failed to load: lazwebdata" (there are a lazwebdata.pas and reglazwebdata.pp files in the demo directory, so that might be something to use somehow) 2. minor, nice to have: Would be nicer to use different project names than extgrid (extgrid.cgi) for people who only use the cgi-bin directory to put CGI programs on their web server installation and do not overwrite the other demo project CGI programs.

1. "The following package failed to load: lazwebdata" (there are a
lazwebdata.pas and reglazwebdata.pp files in the demo directory, so

No, this is the old package name before it was renamed to lazwebextra. I
will check this.
It seems this is just in the .lpi file, when removed in Lazarus from the
project as dependency and removed the .rc line from the project source,
then demo2 compiles OK.
However, demo2 does not want to display anything in the grid despite
writing out the response into a debug file the data seems to be OK. Not
only that, the add/save buttons are working because adding a new record
and saving, then refreshing the grid the debug file shows the new
record. It just doesn't display anything in the grid here.
This is interesting because there are virtually no differences between
demo and demo2 .html and .js files.
ROUND 2
a; demo
1. xml is working for the first demo, there was no problem, maybe a
reboot helped or something.
b; demo, demo1...demo6
1. minor: In the *.js files iconCls are used a few times, however, there
are no 'icon-add', 'icon-delete' and 'icon-save' css parts included (and
those are not included in the extjs release either) so background images
are not shown for the toolbar buttons.
ex. somewhere there should be a
.icon-add
{
background:url(/images/add.gif) 0 no-repeat !important;
}
etc. or similar defined to see button images (of course the gifs are
also needed)
c; demo6
1. in extgrid.ini is that a real user name and password ;)
I will play further and try to figure out why the grid in demo2 doesn't
show anything despite the data replied seems OK both with JSON and XML.

In test#1, it seemed to be success. When I access the webserver with
browser, apache respond normal page.
In test#2, apache shows no error. But process terminate. And when I
accessed the webserver, apache didn't respond.
It is possible to develop by using FPC 2.2.4. However, the future, I
want to compile with a newer version of FPC. Is there any idea to
running module with FPC 2.4.x?
Thanks,
Takashi
There were problems with apache modules that were fixed in the latest
FPC SVN (bug report 19184).
If you do not want to use the SVN versions of FPC/Lazarus, you can just
download the latest packages/fcl-web/src/base/ files from SVN into your
project directory and recompile your project.
Also, make sure you compile with the httpd22 directory and that
FPC/Lazarus is not accidentally uses httpd13 or httpd20 . The best if
you just delete these two directories from your fpc units directory.

No error message in the apache error.log? Apache always says something when the startup is not successful. Your small example library code is working here (Ubuntu 10.10, FPC 2.5.1 SVN), httpd13 and httpd20 directories are deleted.

Re: [fpc-pascal] Freepascal templating engines with logical structures
You do not need to use javascript. There are examples for fpTemplate on
how to do this. See .../packages/fcl-base/texts/fptemplate.txt for details.
Examples are in .../packages/fcl-web/examples/fptemplate/...
All your logic (loop) can be in your fpc source code for grids.
What you seem to want is something php-like, to interpret commands from
the html template. But that way the program logic and display template
would not be separate.

Hello all,
I Know two templating engines for Freepascal: FPTemplate e JTemplate.
Both can be successfully used for html construction.
But they presents the same aspect: only searches and replaces tags to values.
Of course, it's crucial. But to show html grids, obtained from
database queries, it would be better if the templating engine had
support for logical structures. Something like:
<%
for row in rows do
begin
write('');
for cell in cells do
writeln('%s', [cell]);
write('');
end;
%>
It's only an example. The engine can use a syntax different from Pascal.
But what I really like is not to use Javascript. Yes, in the Pascal
side, I could write a JSON and certainly, there would be several
Javascript libraries to show a grid from a JSON. However, I would like
a pure Pascal solution.
Are there templating engines in Pascal with support for logical structures?

Re: [fpc-pascal] fptemplate example wrong?
The OnGetParam and OnReplaceTag are two totally different ways to handle templates. The former is the original version found in FPC packages, the latter is the newer, more Delphi-like - although enhanced - way to do templates. The two are mutually exclusive and controlled by the AllowTagParams flag (false -> old way, true -> new way). The fptemplate.txt file under the FPC sources, .../packages/fcl-base/texts/fptemplate.txt might help a little. All the examples should work, BTW, with the new way, under .../packages/fcl-web/examples/fptemplate/...

Re: [fpc-pascal] fcl-web: retrieve URI given TFPWebModule and TFPWebAction instances
I am not sure about the Embedded Webserver as I have never used it, but I remember vaguely about some kind of problem we have fixed regarding pathinfo with Apache 2.4 and the mod_proxi_fcgi a few years ago. There was a bug report, let me see if I can find it: ... http://bugs.freepascal.org/view.php?id=23387 In it you can see that with Apache 2.4 you have had to do some tricks in the conf file to even get the pathinfo passed from the web server (in the bug report "Steps To Reproduce" section): #No PATH_INFO with mod_proxy_fcgi unless this is set SetEnvIf Request_URI . proxy-fcgi-pathinfo=1 See also the "Additional Information" section for detailed Apache doc on the issue. So, it is possible, that for the URI we can have the same kind of issue. I am not using the URI parameter myself in my projects - might be because it was never set - it seems the others were sufficient or the URI can be rebuilt from the remaining ones. Michael can probably shed some more light on this issue. AB On 5/1/2015 20:59, leledumbo wrote: ARequest.URI ? Forgot to mention that there is a global Request property which is the same.

Usually, the problem with ExtJS 3.x is not with the slowness of JSON itself compared to binary communication, but with the thousands of DOM elements you need to create to display such a big set of data using javascript on client browser side. Of course, it is still a 4.0.x version at the moment, so I would wait until 4.1 at least before using it in a production environment.

You should check the communication in your browser using FireBug or the debug tool in your browser if you use something other than FF (Opera, Chromium, Chrome has also built in debugger with pressing F12), and check if the query string parameters (module, action) as well as your POST fields (form data) are really passed the same way to the server with both GET and POST. The only difference should be the Request Method . I have a feeling that your form data does not come at all from the javascript caller for some reason.
