Re: Debconf and PackageKit

[Daniel Nicoletti <dantti85-debian@yahoo.com.br>]

I don't know if there is a better list to ask this
question but as people here know dpkg
well i'd like to know if there is some
way of telling it to use another fd as
stdin, I have done the following code
to handle answering to conffile prompts
but it works some times and other times it
doesn't... (a bit unpredictable):

This is the forked code, the parent
does a write(writeToChild[1], "n\n", 2);

if (m_child_pid == 0) {
                        cout << "FORKED: installPackages(): DoInstall" << endl;
                        // close Forked stdout and the read end of the pipe
                        close(readFromChildFD[0]);
                        close(writeToChildFD[1]);

                        // redirect writeToChildFD to stdin
                        if (dup2(writeToChildFD[0], 0) != 0) {
                                cerr << "dup2 failed to stdin" << endl;
                                close(readFromChildFD[1]);
                                close(writeToChildFD[0]);
                                _exit(1);
                        }
                        close(1);

                        // Change the locale AND lang to not get it localized
                        setenv("LANG", "C", 1);
                        setlocale(LC_ALL, "C");

                        // Pass the write end of the pipe to the install function
                        res = PM->DoInstallPostFork(readFromChildFD[1]);

                        // dump errors into cerr (pass it to the parent process)
                        _error->DumpErrors();

                        // HACK: try to correct the situation
                        if(res == pkgPackageManager::Failed) {
                                cerr << "Aptcc: A package failed to install.  Trying to recover:" << endl;
                                system("dpkg --configure -a");
                        }

                        close(readFromChildFD[1]);
                        close(writeToChildFD[0]);

                        _exit(res);
}



Thanks,
Daniel.
