PackageInstaller crash with personalStudio

[miqlas]

I tested personalStudio that i downloaded from BeShare (personalStudio_1.5_en_tri.pkg) on Haiku R28283. It installed correctly but ont the end of the install process the PackageInstaller give an error massage: "The application PackageInstaller encountered an error..."

I get this in the debugger:

It seems that after the installation is finished and all created pkg_profiles are freed, one profile has an invalid PkgDirectory pointer in its list of files. It looks like a double free, or maybe some kind of a invalid file addition to the list prior to freeing. It would probably help if I could see the actual package. Since right now I do not have access to BeShare, I would be grateful if you could upload it somewhere in public.

I will try to take care of this as soon as possible.

I finally found some time to look into this problem, and located the bug that was responsible for this behavior. It's a quite serious one even. It seems that I left some 'probably' old code that should be removed in the final version, that - in fact - if more than one profile existed that used the same files to install, tried to free the same memory locations many times.

Attaching patch diff. I would be grateful if someone could commit it. Thanks!

Corrected svn diff of the patch

[sil2100]

I resubmitted the patch, since I just found that I forgot yet another obvious thing during program design.

Applied in hrev28829, thanks! Can you give it another try miqlas?

[miqlas]

Yes, i will try it after the exams. Thanks for the fix :)

[sil2100]

Did you have time to try it again, miqlas? Since I cannot reproduce the error here, I assume that fixed it - we can reopen the ticket if your tests show otherwise.

sil2100, I tested with the current Haiku version, and it installed without problems. Thanks for the fix :)
