It was written to create a rpm and to easily debug the rpm building. Using the tmp directory is per se a security risk. It would be better to use the home directory by default. But this does not work on some systems. The best ad hoc solution is already mentioned in the link: don't add the scripts to the rpm.

Re: [Lazarus] Security issue (symlink attack) in Lazarus filed on Fedora's bugzilla
Just some ideas on the topic. IMHO the tmp-dir should have a random, or pseudo-random element to it, and the current script should not (at least not without asking) delete a tmp-dir. A random element (such as the PID ) would solve issues if 2 different users run the script simultaneously (e.g if both install a local copy of lazarus into their home dirs). In terms of security it would make any attack on the tmp dirs harder. This example also shows why existing temp dirs should not be deleted (without asking). They could still be in use. I have not checked the current script (and neither am I an expert on shell scripting), but I assume that the script removes it temp script on exit? And "trap" could be used to make sure this happens even if aborted?

You should create a temporary name or check and see where the symlink follows before executing/removing it. So if it does not point for the right direction, you just exit with an error.

Re: [Lazarus] How to create a Wizard (InstallShield type) interface
Why do you need a PageControl? I created a "questionaire" thing once, which would have a "mainpanel" And each "page" is a separate form. Then on the "next" button all you do is Make the panel the "parent" of the form, and make the form visible. (remember to align the form AlClient) (or is it maximized)? Hide the previous one, and set the parent to nil (or you could probably leave it as a child to the panel).

I'm not sure if it works After thinking about it for a while it hit me!! The code I'm working with is from the tiOPF project.

Simply passing in a different parameter to the program, different output methods can be used.

[Lazarus] Seeking to resolve LCL in DLL problems
Hi I'm looking at trying to resolve the issue of forms not working properly in DLLs, and thought canvassing opinions from those more intimately aquainted with the source might be beneficial. I know it's not slated to be recolved until post v1.0, but I can't wait that long! What I'm currently looking at is using a mechanism whereby the host application maintains a list of additional objects (whether applications or forms) to it's own, and in the message-loop passes the messages to those first, before trying to process them itself. This is similar-ish to how Delphi handles some of it (a call to SetHandle adds a ref to a process list which is checked in the message-loop), but of course the abstraction layers are different here, so something similar but different is required. My current thinking is that when an app wants to use a form in a library, the process should be. (i) Library is loaded, either statically or dynamically (ii) DLL has an exported function 'SetHostApplication(HostApp:TApplication):TApplication;' before the host app can use a form, it must call something like DLLApp:=SetHostApplication(Application); and inside the dll the application object passed should be stored (in a global or whatever is appropriate), and its own Application object should be returned. The host and the dll now both know about each other. (iii) After calling SetHostApplication, the received DLLApp is registered into an internal list in TApplication - let's call it fChildApps - using a procedure RegisterChildApp(DLLApp);... (iv) In the Host's message-loop it iterates fChildApps calling a procedure to attempt to process the current message [if it's keyboard or mouse related]. If it is handled, the host proceeds to the next message, if not it handles it itself. At the end of the loop, a call should be made to each of the fChildApps.ProcessMessages which calls the relevant Widgetset.AppProcessMessages. (v) When a dll is done, if dynamically unloaded, a call should be made to UnRegisterChildApp. Hmmm - looks complicated! What I'm currently wrestlting with is where the message handling should take place. Using the new PrcoessAsyncCallQueue is probably not the place to do it, since the mechanism is different. Ideally it would be nice to wrap stuff up on a high level, but pragmatically that's not going to happen, since each OS handles stuff differently, so each widgetset's AppProcessMessages is the place to implement the details of it. It may even be worth having an AppProcessSingleMessage.. OK, I'm starting to ramble, so back to the point. Essentially I'm propsoing a system of callbacks, where a dll is registered with the host, and the host feeds messages back as appropriate. It will need to be implemented at both TApplication and TWidgetSet level, and do it gracefully. Also it will require a clear head on the part of end developers, but if the process can be stripped back to Host calls a single procedure to register/unregister a dll, and the dll writer accepts responsibility to export a function (or maybe two) then it could probably be streamlined quite well. Caveats will need to be taken care of, like an application not being able to register itself in it's callback/child list. Messages should probably passed TApplication to TApplication, so that each message can be handled by the lower level widgetsets correctly (it could well be that a GTK application could load a dll using QT, etc). This will add function calling overheads so care will be needed not to kill performance... It could be that TApplications are the wrong thing to be holding, and that just the TForms are what should be registered, but the danger here is of forms being freed without the DLL developer remembering to UnRegister the form, so doing it at the TApplication level should take care of that. When implemented, a new item could then be added to the repository for 'Library with Forms', which has the correct exports already in place, reducing the developer error.. Right - who thinks what? :-) Duncan Parsons ___ Lazarus mailing list Lazarus@lazarus.freepascal.org http://www.lazarus.freepascal.org/mailman/listinfo/lazarus

Now I want a feature to "Select" a piece of code, and then "Apply" the current *code tool options *on the selected code. Because all my old code doesn't look as neat. Obviously if you are working on SVN, and your options differ from other developers, you shouldn't be applying it to all the code... Does this sound like a not so hard to implement feature request? I am guessing that the code used to alter the "example" source code in the options form should be able to be applied on the "selected" code in the implementation of the feature.

[Lazarus] Word of warning when sharing code between Delphi and FPC
Hi Everybody, I have been battling with some code in tiOPF that causes problems when compiled with Delphi 2007, but not with Delphi 7 and FPC. After some head scratching, we found the problem. I use {$IFDEF DEBUG} quite often in my code, to hide things like writeln() statemens. I then have a commented DEBUG define at the top of the unit, so I can enable it per unit when required. That's just how I work... ;-) Anyway in Delphi 2007 there are two compilable states, Release and Debug, with one of those terms automatically added to the options at compile time. Debug mode is the default, which means the DEBUG define is ALWAYS defined - and what caused the problem! writeln() statements fail in a Windows GUI application because StdOut is not available. Just thought I might share this experience with you guys - to minimize future head scratching. ;-) Regards, - Graeme - ___ fpGUI - a cross-platform Free Pascal GUI toolkit http://opensoft.homeip.net/fpgui/ ___ Lazarus mailing list Lazarus@lazarus.freepascal.org http://www.lazarus.freepascal.org/mailman/listinfo/lazarus
