- -******************************************************************************** -* Execution of DrakX *********************************************************** -******************************************************************************** -DrakX has originally be written by pixel in perl and C. -entry point for stage2 is /usr/bin/runinstall2 which is typically a link to -/usr/bin/install2 which simply load module install2.pm and execute -install2::main with @ARGV. - -install2::main parse command line arguments, prepare installation, find the right -install_interactive class (take a look at gi/docs/object_class.fig) according to -command line, memory available and if the interactive chosen is initializing -correctly, else it will try a less-demanding interactive object. -Once done, $::o is set to this install & interactive object and main runs the -various step of install2 defined in $o->{steps}, starting with $o->{steps}{first} -and iterating with method install_any::getNextStep(). -while running step, it trap any errors that may arise and use perl exception to -change step. - -******************************************************************************** -* DrakX modules descriptions *************************************************** -******************************************************************************** -Here is a brief description of what each modules of DrakX is doing. - -install2: main module of DrakX as described above, main loop execution of DrakX. - -install_steps: generic installation module containing steps definition, all steps - should always be defined here as some methods may be used on automatic mode. - there is no interactivity available. typically are defined base operation for - configuring each step according to $o. - -install_steps_interactive: generic installation module with generic interative - methods. typically are found all interactive code of DrakX for each steps. - -install_steps_auto_install: implementation installation module without interactive - methods to match auto_install mode. this is the simplest as almost no method are - redefined (inherit module install_steps only, compared to other implementation - modules described below). - -install_steps_stdio: implementation installation module with interactive stdio - methods to match stdio mode. inherit modules install_steps_interactive and - interactive_stdio. - -install_steps_newt: implementation installation module with interactive newt - methods to match newt mode. inherit modules install_steps_interactive and - interactive_newt. - -install_steps_gtk: implementation installation module with interactive gtk - methods to match gtk mode. inherit modules install_steps_interactive and - interactive_gtk. - -install_any: contains various methods using generic interactive interface but - not used by standalone tools. - -install_gtk: contains various methods using gtk interface but not used by - standalone tools. - -interactive_stdio: implementation methods for interactivity in stdio mode. - inherit module interactive. - -interactive_newt: implementation methods for interactivity in newt mode. - inherit module interactive. - -interactive_gtk: implementation methods for interactivity in gtk mode. - inherit module interactive. - -my_gtk: basic gtk access methods. - -any: contains various methods using generic interactive interface. to compare - against install_any module as this one is available for standalone tools. - -class_discard: simple module that implement every methods undefined to return - nothing. this trick is used to ensure no undefined method can arise when using - code that reference interactive method which are not defined. - -common: contains very simple and very usefull (common) methods to do various task. - some methods inspired by functionnal language. - -c: contains wrapper to C definition of methods used by DrakX, use of C is necessary - for C extern libraries interface (rpmlib, ldetect), kernel interface, XFree - interface. - -commands: implement some un*x commands, conflicting name with perl contains - trailing underscore (_). this module is used by commands perl script that - determine which command to run according to $0 (this is used this way when DrakX - is running). - -run_program: allow running a program with redirection but without using a shell. - allow rooted execution. - -help: contains all help message displayed by DrakX. - -log: log facility methods. - -lang: language manipulation methods, get and set sysconfig file, load po. - -keyboard: keyboard manipulation methods, get and set sysconfig file, set console - keyboard mapping. - -mouse: mouse manipulation methods, get and set sysconfig file, change mouse. - -timezone: time zone manipulation methods, get and set timezone. - -services: services manipulation methods, activate or delete services (see - /etc/rc.d/init.d directories). - -detect_devices: manage detection of various class of hardware. - -devices: manage device file, create device special according device name. - -partition_table: base partition table management methods, it manages - appriopriate partition_table_XXX object according to what has been read - as XXX partition table type. - -partition_table_raw: generic class for the following partition_table_XXX. - -partition_table_emtpy: matches an empty partition table. - -partition_table_dos: matches a DOS partition table. - -partition_table_bsd: matches a BSD partition table. - -partition_table_mac: matches an Apple partition table. - -partition_table_sun: matches a Sun Label partition table. - -fs: read and write /etc/fstab file, mount and umount, format. - -fsedit: manage (modyfy, edit) mount point associated to partition (like editing - /etc/fstab). - -swap: swap management methods, format and mount (activation). - -raid: raid (software only) management methods. - -lvm: lvm (Logical Volume Manager) management methods. - -loopback: loopback management methods, used for lnx4win type installation or using - a file as a partition. - -diskdrake: diskdrake itself, disk graphical (using gtk) manipulation tools. - -ftp: ftp mangement methods, used when using ftp install. - -http: http management methods, used when using http install. - -modparm: kernel modules options management, allow building nice dialog with each - module parameter available. - -modules: kernel modules management, allow loading or unloading (ala modprobe or - insmod). - -printer: printer management methods, read and write both LPR or CUPS configuration. - -printerdrake: interactive printer management methods. - -network: network management methods, get and set sysconfig file. - -netconnect: network configuration wizard. - -netconnect_const: network configuration wirard data. - -Xconfig: X configuration (monitor + already existing config file) management. - -Xconfigurator: X configuration wizard. - -Xconfigurator_const: X configuration wizard data. - -booloader: bootloader (LILO, GRUB, LOADLIN, SILO) configuration management methods. - -pkgs: rpm package and hdlist, depslist management methods, allow selecting or - unselecting packages, manage rpmsrate file and select group, installation and - removal methods of rpm file. - -crypto: *obsoleted* module to manage crypto site and rpm file. - -standalone: standalone only, allow defining a standalone tools. - -bootlook: standalone only, interface with DrakConf to configure bootloader options. - -drakfirewall: standalone only, interface with DrakConf to configure a tiny firewall. - -******************************************************************************** -* DrakX FAT resizer module description ***************************************** -******************************************************************************** -here is a fat resizer written in perl and C used by DrakX (diskdrake) to resize -FAT16/FAT32 partition. it moves clusters to make sure a shrink can be done on the -limit of the partition itself, if no cluster need to be moved, only boot sector -partition limit are modified. - -any: various methods to flag cluster, compute min size. - -boot_sector: boot sector management methods. - -c_rewritten: originally resize_fat was only perl, this contains code section that - are the most sensible to speed or memory contraints and have been rewritten to C - using perl extension. - -dir_entry: manage directory structure. - -directory: traverse directory recursively, needed to move correctly cluster. - -fat: manage fat structure. - -info_sector: manage info sector. - -io: manage I/O on disk (need to take care of big file as partition size may be - larger than 2GB). - -main: main resizer algortihm. if needed allocate new clusters, copy files, copy - directories. update boot sector info. - -******************************************************************************** -* Adding a new step to DrakX *************************************************** -******************************************************************************** -Say we want to add a question for setting "alawindows" option. -We put it pretty early in the install, let's say after "Select Installation -Class". - -1. in install2.pm - -add - - selectAlawindows => [ __("A la windows or not"), 0, 1, '' ], - -after - - selectInstallClass => [ __("Select installation class"), 1, 1, '' ], - -the 0, 1, '' means not "redoable", "skip on error", "don't hide" - -2. add your function selectAlawindows in install2.pm - -sub selectAlawindows { $o->selectAlawindows } - -3. add your function selectAlawindows in install_steps_interactive.pm - -sub selectAlawindows { - my ($o) = @_; - $o->{alawindows} = $o->ask_yesorno('', _("Throw everything away as windobe does?"), 1); -} - -4. add your function selectAlawindows in install_steps.pm (not needed in that -case, except for auto_install) -
