* configure: Use AC_GNU_SOURCEJeremy Kerr2013-12-1819-30/+29
| | | | | | | Rather than #defining _GNU_SOURCE in our .c files, we can define this from config.h instead. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* ui/ncurses: Add link status to system info & system config screensJeremy Kerr2013-12-182-3/+9
| | | | Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* lib/util: Move mac_buf from nc code to util libraryJeremy Kerr2013-12-181-22/+4
| | | | Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* ui/ncurses/boot-editor: Fix (null) when non-device resources are shownJeremy Kerr2013-12-031-1/+1
| | | | | | | | | | | We're seeing the following in the boot editor: image: (null)ftp://... the (null) is due to the sep in conditional_prefix, which should be blank, not NULL. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* ui/ncurses: Add key debugJeremy Kerr2013-12-021-0/+2
| | | | Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* ui/ncurses/nc-widgets: Unify select keyJeremy Kerr2013-11-221-15/+11
| | | | | | | | We have a few instances where we check for a 'select' action (enter or space key event), and some are inconsistent. Unify these with a key_is_select() function. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* ui/ncurses: Redraw entire screen with ctrl+LJeremy Kerr2013-11-221-4/+2
| | | | | | Use wrefresh(curscr) to clean and repaint the entire screen. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* ui/ncurses: Ensure boot editor window is properly paintedJeremy Kerr2013-11-221-0/+2
| | | | | | | We're not currently drawing the window title correctly; we need to draw the main_ncw for this to hit the terminal. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* ui/ncurses: Fix use-after-free when exiting boot option editorJeremy Kerr2013-11-221-13/+29
| | | | | | | | After we've called on_exit, we can no longer use the boot editor. This change moves individual button callbacks into process_key, which returns to the main loop. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* ui/ncurses: Allow boot editor sysinfo updatesJeremy Kerr2013-11-222-65/+99
| | | | | | | We may start a boot editor (via 'New') before we have the sysinfo. To allow this, we redraw the device select. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* ui/ncurses: Add widgetset_set_windowJeremy Kerr2013-11-222-0/+9
| | | | Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* ui/ncurses: Add widget_select_drop_optionsJeremy Kerr2013-11-222-0/+40
| | | | | | We want to be able to re-set the options in a select widget. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* ui/ncurses: Implement intra-field scrollingJeremy Kerr2013-11-222-12/+10
| | | | | | | Now that we can calculate the focus within a field, ensure that the focussed-element remains scrolled. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* ui/ncurses/widgets: Add widget focus offset queryJeremy Kerr2013-11-222-0/+24
| | | | | | | | | | When we have widgets that are larger than the screen, we'd like to scroll to the currently-focussed component of that widget. This change introduces a widget_focus_y function, which returns the y offset of the field's focus. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* ui/ncurses: Draw boot editor into a scrollable padJeremy Kerr2013-11-221-5/+51
| | | | | | | | Like the config editor, draw the boot editor into a pad instead of directly into the sub window. This means that long device lists will be handled correctly. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* ui/ncurses: Make boot editor paths relative to deviceJeremy Kerr2013-11-221-1/+65
| | | | Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* ui/ncurses: Add device selector to boot editorJeremy Kerr2013-11-221-4/+93
| | | | | | | | Rather than expecting users to enter full (prefixed) mount paths, add a select widget to pick a device, and we automatically add the prefix when the form is submitted. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* ui/ncurses/widgets: Add n_options check to widget_select_get_valueJeremy Kerr2013-11-221-0/+2
| | | | Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* ui/ncurses: Split boot editor layoutJeremy Kerr2013-11-221-29/+59
| | | | | | | We want to make the boot editor dynamic later, so split the widget layout from the widget creation. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* ui/ncurses: Make boot editor API consistent with config & sysinfo screensJeremy Kerr2013-11-226-105/+108
| | | | | | | | | | | | The boot-editor API is a little more exposed than it needs to be: the boot_editor struct does not need to be available to other files, and the init function and on_exit functions differ from those provided for the config and sysinfo screens. This change unifies the boot_editor API with those for the other screens. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* ui/ncurses: remove boot_editor_attr_fieldJeremy Kerr2013-11-221-5/+0
| | | | | | The widgetset code handles these attributes now. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* ui/ncurses: Add block devices to system info screenJeremy Kerr2013-11-221-2/+17
| | | | Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* ui/ncurses: Fix pad size checkJeremy Kerr2013-11-191-1/+1
| | | | | | We need the y-coord, not x. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* ui/ncurses: Don't mess with prog_mode in cui_bootJeremy Kerr2013-11-191-5/+0
| | | | | | | The discover_client_boot call is asynchronous, so setting and resetting prog_mode doesn't gain us anything. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* ui/ncurses/menu: Allow space to select menu itemsJeremy Kerr2013-11-141-0/+1
| | | | | | To keep consistent with buttons, which also accept space. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* ui/ncurses: Add descriptive text for configuration editorJeremy Kerr2013-11-141-12/+44
| | | | | | | | This change adds: - 'seconds' to the timeout text entry - examples to the ip/mask, gateway and DNS text entries Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* ui/ncurses/nc-config: Draw config form into a scrollable padJeremy Kerr2013-11-141-4/+70
| | | | | | | | | | Currently, when the config form is larger than the screen size, the form fails to draw. This change draws the config screen onto a pad instead, which we can scroll. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* nui/ncurses: Allow config screen updatesJeremy Kerr2013-11-143-9/+50
| | | | | | | | We may receive configuration (or sysinfo) data after the configuration screen has been displayed. Implement config_screen_update and redraw the widgetset when new config data arrives. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* ui/ncurses: Add help for the DNS optionJeremy Kerr2013-11-141-1/+14
| | | | | | It's not obvious why it's there when we're configuring DHCP. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* ui/ncurses: Populate configuration interface with current defaultsJeremy Kerr2013-11-141-14/+85
| | | | | | | Sets the default values of configuration widgets to the values found in t he current config. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* ui/ncurses: Parse configuration form & send to serverJeremy Kerr2013-11-145-10/+135
| | | | | | | This change implements the configuration save action, when the user submits the nc-config form. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* ui/ncurses: Add network configurationJeremy Kerr2013-11-141-8/+130
| | | | | | | Add network configuration parameters. This requires a somewhat-dynamic layout, as the fields shown depend on earlier configuration. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* ui/ncurses: Add basic config editorJeremy Kerr2013-11-148-3/+283
| | | | | | This change adds a simple configuration editor to the ncurses UI. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* ui/ncurses: Receive config messagesJeremy Kerr2013-11-132-0/+8
| | | | | | We just store the config in the cui for now. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* ui/ncurses: Use nc-widgets for boot editorJeremy Kerr2013-11-132-240/+75
| | | | | | | Now that we have a simple widget set available, use this for the boot editor. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* ui/ncurses: Add simple ncurses form widget setJeremy Kerr2013-11-133-1/+804
| | | | | | | | | We're doing a lot of the same stuff with forms, and we'll to implement a lot of fields with the upcoming configuration interface. This change introduces a simple ncurses widget set. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* ui/ncurses: Add sysinfo screenJeremy Kerr2013-11-138-8/+332
| | | | | | | | Add a simple screen for displaying the struct system_info. We add this to the main menu as a selectable option, and separate it from the boot option list with an unselectable blank entry. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* ui/ncurses/scr: Add definition for frame offsetJeremy Kerr2013-11-132-1/+2
| | | | Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* ui/ncurses: nc-menu.h needs assert.hJeremy Kerr2013-11-131-0/+2
| | | | Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* ui/common: Don't talloc_free sysinfo and status explicitlyJeremy Kerr2013-11-132-8/+21
| | | | | | | | | | | | | Currently, we talloc_free() the sysinfo and status messages in the discover client, right after performing the ui's callback. However, the client may wish to keep a reference to this information beyond the callback invocation. This change introduces a per-message talloc context, which these structures are allocated under. This allows the callbacks to talloc_steal() anything they wish to keep a reference to. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* ui/ncurses: Add nc_scr_{un,}post()Jeremy Kerr2013-11-134-11/+29
| | | | | | | We may have nc_scrs that aren't interested in post/unpost information, so create helper functions that allow a NULL callback. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* ui/ncurses: Move general nc init code to cui moduleJeremy Kerr2013-11-133-35/+32
| | | | Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* config: Implement config messagesJeremy Kerr2013-11-132-0/+19
| | | | | | On client connect, send a PB_PROTOCOL_ACTION_CONFIG message. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* logging: Clean up debug logsJeremy Kerr2013-11-0110-40/+27
| | | | | | | We have quite a few pb_logs which should be pb_debug. This change moves developer-specific info to pb_debug. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* ui/ncurses: Use OK & Cancel buttons for boot editor completionJeremy Kerr2013-10-112-6/+47
| | | | | | | Rather than using enter to complete a boot_editor session, add OK and Cancel buttons. Enter will move between fields. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* ui/ncurses: Use 'x' as exit keyJeremy Kerr2013-10-114-5/+6
| | | | | | | | | | | Because terminals will send escape-sequences starting with escape, ncurses will pause after receiving a signle escape, to detect these sequences. This introduces a 1-second delay when exiting the petitboot UI. Instead, use 'x'. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* ui/ncurses: Allow booting custom boot optionsJeremy Kerr2013-10-102-6/+1
| | | | | | | Currently, we can't boot user-created boot options, as they have no option ID associated. This change removes the check for option ID. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* ui/ncurses: Defer item creation until boot editor is doneJeremy Kerr2013-10-108-93/+88
| | | | | | | | | | | | Currently, when creating new menu entries, we create an empty item, add it to the menu, then run the boot editor. This means that cancelling the edit will leave an empty item in the menu. This change defers the creation until the boot editor is done. To do this, we modify the on_open callback to take a menu rather than an item, and pass NULL boot data to the editor. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* ui/ncurses: Use 'New' instead of 'Open'Jeremy Kerr2013-10-102-3/+2
| | | | | | "Open" is ambiguous in the context of the boot menu; use "new" instead. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
* ui/ncurses: Display sysinfo type & identifierJeremy Kerr2013-10-096-5/+46
| | | | | | | Hook into the sysinfo updates to display the type & id at the top of the petitboot main menu. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
