Re: [Lazarus] FPWeb/Weblaz New Exemples: Error
The examples only work with FPC sources later than 4/30/2009 when the last patch (http://bugs.freepascal.org/view.php?id=13254) of fcl-web was implemented. You need to get the latest FPC fcl-web source codes for them to work. It is possible to just replace the files in your /packages/fcl-web/src/*.* and then recompile FPC and then Lazarus if that is easier for you.

Re: [Lazarus] jQuery interface for fcl-web
Adding fcgi-support was only two hours work. Other systems can be added as wel. Next on my list is a native web-server using lnet, so that debugging is even easier. (I'm absolutely sure that posting all messages about fcl-web not supportinf fcgi was more work then actually adding the support) I thought the fcgi support is still a work in progress. The other day I was trying to create a "hello world" fcgi program just to see how it works but it did not compile. Getting a "fastcgi.pp(1,1) Fatal: Can't find unit BaseUnix used by custfcgi" error. (Latest Lazarus and FPC SVN, win32 /XP/) If it works, I would make the examples submitted in http://bugs.freepascal.org/view.php?id=13706 to work as FCGI also. BTW, there should be some explanation in Lazarus -> File -> New for people about the differences between Application - Program - Custom Program ; Simple CGI Application - CGI Application - Custom CGI Application ; FastCGI Application - Custom FastCGI Application ; I am positive, it is very confusing for a newcomer to chose between these. In fact, I'm sure it is random chance at the moment that decides which they are clicking on within one group.

Re: [Lazarus] Error while debugging: "No symbol in current context"
Hi Graeme, The debugger is not usable as it does not have been in the focus to be developed. Object property values cannot be seen either (dwarf or something external program used does not support properties). There were questions about the debugger functions in the past 2 years, same as yours both on the Lazarus forums and the mailing lists. If I remember correctly the answer was something like it is not priority until after 1.0 . IMO it is one of the most important aspects of RAD development to have a fully working IDE debugger. Currently in Lazarus the debugger is not usable for serious development because some of the most basic requirements are missing. Not to mention a CPU window, etc. It seems a new debugger should be developed that does not depend on non compatible external programs, but there were no resources to do it in the past years.

[Lazarus] Lazarus unresponsive if Show Compiler dialog ON and trying to debug
Hi, If one checks the Show Compiler dialog in Lazarus and tries to debug to a line with f4, or place a breakpoint somewhere and execute with f9 Lazarus becomes unresponsive when exiting the application. This is due to 2 dialogs up at the same time, with the smaller one (Execution ended) being right behind the bigger one (Show compiler progress left there from the initial compilation). Nothing should be done until the show compiler progress dialog is closed manually (would be nice to have the focus on it after compilation too, instead of on the messages window so an enter would close it). No execution or debugging or source code editing or anything should happen until this dialog is closed. This major show stopper bug was reported in 2008 in mantis (http://bugs.freepascal.org/view.php?id=12020 and the dozen related reports) and no fixes done since then. I would think that these kinds of problems would have priority because people meet them in the first 10 minutes when starting to use Lazarus. But one and half years with no fixes seems a little bit too long when everyone is so upbeat with open source software getting fixes so faster than proprietary ones. If it cannot or will not be fixed, please remove the show compiler dialog check box from Lazarus so people will not get stumped on it every time they want to see compiler progress.

We might do it FCGI in the future, but it does not seem to be working on Windows (it was a few months ago so I do not exactly remember what was the problem, but I think it was something like many FCGI app instances got spawned and dragged the CPU like crazy all the time even between requests), so we probably need to move to Linux for the server development in case we try to do this again. No frameworks or libs were used, it is a normal website with screens, reports, etc., people need to click on things to get new content.

Did. But in the current economy the traffic is down, and because of CGI doesn't require an Apache restart when anything changes in the app, we are just using CGI at the moment (with HTML templates and template tags using fpTemplate). Did not see speed difference between the two. However, any time the need arises, we can just recompile the app as an Apache module in minutes and us that.

Well, I never coded an Apache_mod, but I think it would be multi-thread, right? Your code is like that? Can you talk more about? Marcos Douglas We write all code as if it were an Apache module (or FCGI), even if we compile it as CGI at the moment. You just need to take care of the fact that web modules already in the memory can be reused for following requests (in case of Apache mods and FCGI), so the global variables, web module variables (private and public), etc. can have values left over from previous requests. Especially, need to take care of closing connections, files, free used memory, etc. after a request is finished and put back things to the initial state before leaving, so the next request that might get the same web module for action handling will find the same state as the previous. This is the same for Apache modules and FCGI. Only the .lpi and .lpr files (they are all very small and after creating them the first time no changes are needed at all) are different between Apache module, FCGI and CGI applications, the web module file is the same (example: under your Lazarus directory in /components/fpweb/demo/fptemplate/sessions/urlsessions-login/).

Yes, this is true. See the demo program under your Lazarus diretory
/components/fpweb/demo/fptemplate/listrecords/
You can use a tag in your template and complete eliminate html code in
your pascal code. From the above demo program the template file contains:
{+REPORTRESULT
[-HEADER=
class="Label">
~Column1
~Column2
-]
[- ONEROW =
~Column1Value~Column2value
-]
.
.snip, and so on more parameters if needed
.
[- NOTFOUND=
There are no entries found.
-]
[-FOOTER=-]
+}
This is a single template tag with tag parameters to generate a full
html table as you please. In the above example the pascal module only
replaces the actual values in the table header and rows (marked by tilde
"~").

The filename might need to be between double quotes, like
AResponse.CustomHeaders.Add('Content-Disposition= attachment;
filename="blah blah.csv"');
because there might be some spaces in the name for example.
Also, I am not sure but does the AResponse.ContentStream need to be
freed after the SendContent or SendResponse? If I remember right, back
it old delphi days with the proper way, the stream was not freed. Not
sure how it works in FPC/Lazarus though.

This is necessary to overcome the asymmetry of the http protocol.
IMHO "Server-Events" are necessary to design a CGI program with some
complexity.
Well, I create seriously complex applications. No such mechanism was
necessary till now.
Hmm, How to do notify the user that the server has finished complex
work in the background without blocking the interface and/or creating
excessive http polling traffic ?
Define excessive polling ?
An easy to do (non complex) example for a good application for such a
method is a server that allows tow client to chat.
Moreover "server-Internal-Events" like from Timers, serial or
"direct" TCP/IP communication, thread-notification, ... are very
desirable and should be able to fire "server-events" towards the
client.
Why ? What could you possibly need to do that the server needs to
contact
the client ? Everything you need can be programmed in the client, in my
experience.
Above trivial example ("chat server")
Real-world: Imagine an "embedded" program automatically working with
some hardware interfaces and/or serial and/or TCP/IP connections. Now
you want to provide it with a "web" interface that allows a "user" to
connect to it and do configuration and monitoring. For monitoring this
method is essential: many "states" in the program permanently change
due to the work of the program and the external situation. These state
changes need to be shown in the remote browser with low latency and
without excessive communication overhead.
In my experience: keeping a connection open IS excessive communication
overhead and very unreliable to boot.
I thought like you, 12 years ago. Till reality kicked in. Faulty switches,
company firewalls and whatnot. Not all servers/firewalls support HTTP 1.1
(for a persistent connection) etc. Too many problems.
So you end up with polling anyway. 10 polls per second is enough to fool
the
human eye and doesn't stress the server too much.
Michael.
Aren't ExtJS Ajax calls asynchronous? The JavaScript code continues
after firing a call to the server. There is a "callback" event that we
can use when the server sent the reply back (and process success/failure
events on the call).
At least I had to do some things to NOT give back the control to the
user over the client side until the response arrives from the FPC server
CGI/FCGI app (like disabling all controls for example).
IMO Exjs and FPC/Lazarus works superbly (you need FPC and Lazarus from
the trunk SVN at the moment for it). You do not need ExtPascal at all.

But I'm certainly open for suggestions for improvements.
Michael.
Well, It's not an issue at all, I could create a stored procedure in
charge of receiveing the params from the dataprovider, then adapt them to
their respective tables. It's not an issue because I usually work with
Firebird and PostgreSql, and they have stored procedures.
I ask this because I'm thinking of adding a new layer of abstraction by
letting the TFPWebProviderDataModule load a configuration from, say, an
XML file with the list of Providers and its Select, Insert, Update, and
Delete statements, like this:
select * from customers
select * from customers where IdCustomer=:IdCustomer
insert into customers(Name, Age)
values(:Name, :Age)
update customers set Name=:Name, Age=:Age
where IdCustomer=:IdCustomer
delete from customers where IdCustomer=:IdCustomer
With this data, the cgi/fcgi app could dynamically create the
TPWebProviderDataModule and everything else.
What do you think about this?
But you can do these things already, I believe.
I had multiple tables and some simple access rights to different people
so my SQL statements had to be different for everyone to get different
records from the tables.
What I did is, I started from the first demo example found in
fcl-web/examples/webdata/demo/
and created ONE action called "CRUD" that handles all the crud request
from the extjs clients. However, I am passing some additional parameters
that specifies which table is to be used and what needs to be done
(Create, Read, Update, Delete). From the session I got who is the user,
so I was able to prepare the proper SQL statements myself.
For example, the extjs data store proxy looks like this in the client
side extjs:
===
var myproxy = new Ext.data.HttpProxy ( {
api : {
//XML
// create: GetCGIURL('/CRUD?format=xml&t=0&d=0'),
// read:GetCGIURL('/CRUD?format=xml&t=0&d=1'),
// update: GetCGIURL('/CRUD?format=xml&t=0&d=2'),
// destroy: GetCGIURL('/CRUD?format=xml&t=0&d=3')
//end of XML
//JSON
create: GetCGIURL('/CRUD?t=0&d=0'),
read:GetCGIURL('/CRUD?t=0&d=1'),
update: GetCGIURL('/CRUD?t=0&d=2'),
destroy: GetCGIURL('/CRUD?t=0&d=3')
//end of JSON
}
});
==
You can see that I am passing the "t" and "d" additional parameters. "t"
can be the table/database to use and "d" can be the action to be
performed (create, read, update, delete), etc. In the web module "crud"
action I just need a case statement for the different SQL statements
based on these passed parameters.
Of course it is more complicated to build the actually executed SQL
statements in my app, because I also process the sort order, the number
of records to be returned, and have some record filtering coming form
the extjs client, and as mentioned above, based on the user different
records needs to be returned, etc.
Plus, I created some additional actions in the webmodule for other
things like a "keepalive" call from the client so the session is not
closed if the user uses the client for a long time but there are no
server calls to refresh the session, and so on for other things and
responses, web pages with templates, like login/logout, etc.

Yes, theoretically it can be made a bit cleaner and easier by improving the webdata components, but there are a lot of additional parameters that can come in from Extjs. For example, I am using Extjs grids and processing the following incoming parameters when creating my SQL statements: table(s) to use /an id number what data is needed/ operation to perform /c, r, u, d/ start /starting record/ limit /number of records to return/ sort /sort by this field, this can be tricky for calculated fields/ dir /sort order if needed: ASC DESC/ fields /filter on these fields/ query /value(s) to look for in the filtered fields/ So creating the proper SQL statements definitely involves some work for the different Extjs client grids I use. The access rights for the users for the different database records also need to be taken into account. Additionally, a separate SQL statement is needed to get the total number of records and properly replace it in the response that is returned to the Extjs client. That is, because not all the records are returned, just the ones that fit into one grid page. With thousands plus records it is necessary, so the communication and response time is relatively fast.

I agree that dual-license is tricky, but that has never stopped me from using a toolkit, if it is good. MySQL I simply don't use because it is a bad database engine :-) I think you guys are not exactly correct regarding the ExtJS license. http://lazarus.freepascal.org/index.php/topic,10125.msg52756.html#msg52756 "According to the linked ExtJS licensing FAQ, you have obligations to publish the ExtJS JavaScript code that YOU have modified AND(!) you are distributing it. So, in-house projects are excluded by default, as well as all extensions you have downloaded from the Internet - since those are already published back to the community. As I've noted, I never needed to extend ExtJS so far, always found that someone else did what I needed already. Either case, it does not affect your FPC/Lazarus project parts." In my opinion ExtJS is absolutely the best framework to use on the client side GUI within a browser, and Lazarus/FPC 100% supports it right now (0.9.29/2.51). You do not need ExtPascal or any other additional libraries to build superb systems with it. You do not need to buy ExtJS licenses either. As for MySQL usage...I do not have any problem with using that either in my web projects (Im using ZEOS library to access the DB). It is still by far the most used and available DB for web apps/web servers.

If you use lazarus trunk svn head,with fpc trunk, you must use fpc

must update fpc too.
Vincent
Just as a note, sometimes there can be additional problems with
compiling FPC/Lazarus from SVN.
In both the case of FPC and Lazarus, sometimes a file or two gets moved
between directories in the SVN directory tree and when someone does a
"make clean..." after an "svn update..." the clean will not remove the
older one from the install "units" directory and that can cause problems
with future compiles, rebuilds.
Sometimes I got "checksum changed" error in a file at rebuild, sometimes
packages did not compile, sometimes the rebuild did not find things, etc.
I just had this problem a few days ago when after 2-3 months I updated
my FPC and Lazarus SVN from the trunk and tried to recompile both.
1. First of all I had to delete the target directories of the installed
versions of FPC and Lazarus ("make clean" should do this but since the
moved file is now in a new directory, it tries to delete it from the new
place instead of from the old place therefore leaving the old one there)
2. Then I deleted all SVN checkouts for both FPC and Lazarus and checked
them out again into a clean directory
3. I used the last stable FPC version to compile the new FPC trunk first
(sometimes you can not successfully compile the latest FPC 2.5.1 with a
one or two months old FPC 2.5.1)
4. Then I could compile the latest SVN FPC again with itself (compiled a
2.5.1 with a 2.5.1 made by a 2.4.xconfused enough yet?)
5. Checked out Lazarus from SVN into a clean dir and built it, installed it
6. Removed the Lazarus settings directory before 1st start and then
tested a rebuild from within Lazarus after setting the FPC dir in the
environment menu. If this works without a problem, you can start adding
the packages you use.
7. I had a problem with the latest stable Zeos 6.6.6 because it did not
compile. After looking it up on the net, I found the necessary changes
needed for Zeos to compile (changes were needed in one of the source
files, ZClasses.pas) under FPC 2.5.1.
After a few hours I had a newly working FPC/Lazarus installation.
This all is not for the faint heart... but can be done.

So you don't reach all possible customers. Believe me, I will reach far less customers by not using Javascript, namely: zero. I make a distinction between websites and webapps. We do not make general purpose websites, but web applications for a specific audience. There is a huge difference. These applications must behave and act as a desktop application, this is a requirement. This is not possible without Javascript. Then you may ask, why not simply program a desktop application ? Simple: people do not want an installer or updater. If it was not for that small detail, I would not touch web programming with a long stick. No set standards, different and ever-changing browsers, a language that sucks big time. But alas... Michael. ...And it does not matter what platform they are using, it will work without problems. No drivers needed, no libraries needed, no version issues. Javascript will not go away, it will become more popular over time. This is the trend the last ten years and it just gets more popular as more and more Java apps are ported over. It saves huge bandwidth (not to mention responsiveness and client side speed)to use javascript apps client side with modern browsers. You download the data and until it changes you do not need to talk to the server other than some update checks on the data if it is multi-user. I can not emphasize enough how much time it saved for me to do my projects as javascript (ExtJS based) web apps (using fpweb server side back-end). No matter if the client is Mac, PC or mobile device, it works. As for NoScript addon usage, I am using it too. If the web app I need to use needs Javascript, I enable that one website (but not letting google, and the other crap ad companies to run scripts). You can not get around this. But you need to be pretty aware of this and manage it manually which is not for 99% of web users. A few million NoScript users does not hold a candle to the hundreds of millions without it who does not even know what Java or Javascript is. This is the way the internet works, and it will not change people as the past 30 years show.

Everything is encoded in the action parameters. Both the action name and action parameters are encrypted, and encrypted differently every time.

Do not pull (all) your hair yet :) I was testing FCGI with fpweb the past day or so on Windows, and it seems to be broken and only the FastCgiExternalServer way is working. In fact, you are correct that there is an infinite loop, and that is Apache trying to start up the FCGI application continuously at startup, but it keeps exiting. You can see it in the apache error logs. On Linux, everything works OK for both mod_fastcgi (sources from fastcgi.com/dist) and mod_fcgid that the Apache project develops. For now, I suggest you use the FastCgiExternalServer way on Windows and specify a port in your FCGI app/Apache conf. You need to start the FCGI application before sending the requests to it though because this way Apache does not do it for you. In any case, this is the best way to develop and debug an FCGI application anyway because you can just use breakpoints and the debug facilities from within Lazarus. It will be fixed on Windows as soon as the problem is found, I am sure. We are still trying to find the issue.

Same error. x(
Please, see:

OK, here is what I did to make your downloaded project work (was not
trivial):
1. Unzipped it and moved everything to the same directories
2. Edited the project main .lpr file and changed it to
..
uses
fpFCGI, Unit1, iniwebsession {for the error message}, custfcgi {for
the poStripContentLength};
begin
Application.Port := 2015; //Port the FCGI application is listening on
Application.ProtocolOptions := Application.ProtocolOptions +
[poStripContentLength];//on windows, without this the response can be
cut short
Application.Initialize;
Application.Run;
end.
..
Note, without the iniwebsession we just get an exception complaining
about it (this requirement should be removed from fpweb).
Also, custfcgi is needed so we can add the protocolotions line, so on
Windows the reply is not cut short by Apache (like error messages about
the iniwebsession, for example).
3. in the httpd.conf
LoadModule fastcgi_module
"C:/xampp/apache/modules/mod_fastcgi-2.4.6-AP22.dll"
ScriptAlias /myfcgi "C:/xampp/htdocs/fcgi/test.exe"

Allow from all
FastCgiExternalServer "C:/xampp/htdocs/fcgi/test.exe" -host

5. Start the test.exe application from a cmd window
6. Navigate to http://127.0.0.1:8080/myfcgi/index from my browser to see:

Note, your response generation only sends back the text "Test" instead

And you do not specify the actions in the URLs when multiple web modules are in your application? I think actions are always specified when web modules are in the calling URL. But it is not true the other way around. Well, I never use actions. I always use the OnRequest handler of the module itself. Michael. Heh, then we use fpweb differently (as I am sure other people prefer doing it in many additional ways). :) I use one single web module with dozens of actions compared to multiple web modules with a single request handler that sorts out things. Much simpler and shorter calling URLs needed this way (an important thing when encrypting the action name and request Query parameters), and for me this way gives a nice organized source code in the web module, as all functions are nicely separated into action event handlers. I am sure there are many perfectly good ways - other that the two of us are using - to use fpweb. In my humble opinion, if someone uses Web Actions (and they are there and highly visible in the object inspector - not like web modules -, as well as Delphi-converts most probably know about them already) then Actions have higher priority than web modules in the calling URLs. Logically, - as a design paradigm - a web application has more actions than web modules (not that I can really put a definition on why and when multiple web modules would be needed...). However, if someone is not using Web Actions at all, then this is not true in the case they use multiple web modules. But, since your suggestion to add a TWebHandler.PreferModuleName (Default is False) - or similar - would not break any current projects, it would be an easy addition for the above cases. I also have a question: Could you please list the function of the multiple web modules in your web applications? I never really saw a good use for multiple web modules, but they were implemented more than 10 years ago in Delphi already too, so there must be a reason for that.

Re: [Lazarus] Uses Clause in LPR
I found the same bug in the LazSolutions, and i reported to the developer, who has answered me. http://code.google.com/p/lazsolutions/issues/detail?id=22 He said, that bug is a IDE bug. It is not a bug. It is correct behaviour. The LazSolutionsRT should have the 'add to uses clause' flag not set: in the package dialog, choose options. then 'Package options' - 'Usage' and then uncheck the 'Add package unit to uses section' (no check mark should be present). For Zeos, the same is probably true, but I do not know how the zeos package works. It can be that after this, the same error occurs. If so, it means that somewhere in the zeos code, the lazarus 'interfaces' unit is used, or a unit that depends on the LCL. This unit must be rewritten if you want to use zeos in a CGI or any webserver project. Michael. I am not sure what is the problem in this case, but I am using Zeos for CGI applications since years without any issues. Even gave the 7.0.0 Alpha version a try, though it does not handle the strings properly with FPC/Lazarus unlike the stable 6.6.6 release. With 7.0.0 alpha, sometimes just ?? comes back for string fields due to fpc/lazarus requiring UTF8 strings.

Re: [Lazarus] EmbWeb: Moving between webapp type caveats
Back to the problem, using relative URL is not a solution as well. When I do http://localhost/proj/proj.cgi/module/action then if somewhere I put public/style/style.css then the link becomes: http://localhost/proj/proj.cgi/module/public/style/style.css, regardless of the webapp type (at least on Chrome, don't know about other browsers). Isn't there really a way somehow? Because you need /public/style/style.css indicating that it is a static file from the virtual path starting from document root. public/style/style.css is relative from the current virtual path, which can be anything physically in the file system, depending on the OS or weather you use CGI or Apache module, etc. Also, if your CGI program opens files, it will need full physical paths, we can not use relative paths with it either, because it can be the main root dir on Linux or the Apache main dir (not the document root) on Windows. Usually not the physical path the CGI program resides in. AB -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
Re: [Lazarus] EmbWeb: Moving between webapp type caveats
Set it in some constant? When the webmodule still wasn't working good enough, I used defines with a constant. I use an .ini file, but the same idea. There can be a lot of things that a web app needs as a constant. static paths, email server settings, template paths, url generation parameters (https or http, ports for development computer, etc.), db connection settings, etc. This way it is the easiest to move from a development environment to a live system.

I need to build a server-side application (fcgi is my choice) that gets send some json, processes it and communicates with a mysql database, simple enough. Looks like all this is perfectly doable without any problems with Lazarus and fcl-web, at least the 'gets send some json and processes it'-part I have already done for another project. But it was a pain to develop. For such kind of projects I am used to Java and development in Eclipse. My major problem with Lazarus is where is my server? That depends. In Eclipse I just configure my Tomcat or whatever other container I want to use, press 'run on server' and voila, eclipse starts Tomcat and my application with full logging working inside the IDE to be found at 'http://localhost:8080/myapp'. If I need breakpoints or single stepping, I just start the server in debug mode and all is well. So how do I configure Lazarus to do about the same? It depends on how you set it up. I found some mentioning of fpembweb or lazaruswebdesign packages but nothing concrete about where to find or how to use them. Surely some of you guys do such kind of development with Lazarus and I cannot believe that everybody runs a local apache and copies his executable around after every compile (my apache is on a VM which made it even more work to copy the files around and there was no debugging capability to speak of). So it boils down to let Lazarus run the fcgi app (can be another app type if it is easy to switch it to fcgi for deployment) on an (embedded) server, with logging output shown in the IDE and the option to use a debugger with breakpoints and single stepping. There are 2 options: 1. Use embedded server to do the debugging; that part is easy, it's like running a normal executable. You don't need apache for this. 2. You can run the fastcgi server if you use mod_fastcgi.so, but then you must use the ExternalFastCGIServer option, and configure the fastcgi application to listen on this port: In Apache, configure FastCgiExternalServer /home/michael/public_html/testht -host 127.0.0.1:10020 -idle-timeout 3 -flush Here 10020 is the port to listen on, and /home/michael/public_html/testht is the URL that will be the 'base' url for your fastcgi app. In that case, your fastcgi application must be configured to listen on the same port: Set Application.Port:=10020; in the project source file. Restart apache, run your executable, and do a request through the browser. That's it. Note that you cannot do this with the mod_fcgid module. I do believe that in Apache 2.4, mod_proxy can handle this situation, but I haven't tried yet.
