[master] UTC/localtime HW clock heuristic
by Vratislav Podzimek 05 Jun '13

05 Jun '13

PATCH [1/2] is just a minor change without any significant result. PATCH [2/2] adds a heuristic to guess wheter HW clock uses UTC or local time by searching for bootable NTFS partitions. It adds two threads, but these are really lightweight and just handle the potential long storage initialization.

[master] Patch for exceptions in non-main thread in TUI
by Vratislav Podzimek 04 Mar '13

04 Mar '13

This patch provides a fix for the case when there is an exception in a non-main thread in text mode. It is impossible to run the exception handler in the non-main thread for many reasons. It competes with the main thread for standard input, it cannot run libreport because libreport forks, it cannot quit the installer because the main thread would still be running and probably something else I didn't hit yet. This builds on Martin's patch for processing our message queue in text mode. The only remaining problem is, that when the main thread runs raw_input another call of raw_input from the exception handler is blocked until the first one is finished. Thus one needs to hit ENTER before entering any input for the exception handler. This can be fixed by telling python-meh's exception handler that it should use our raw_input instead of the built-in one but I am leaving this for an additional patch as it needs some changes in python-meh (and thus new build).

[PATCH] Teach TUI how to react on async events
by Martin Sivak 21 Feb '13

21 Feb '13

This involves couple of places: - TUI is blocking and waiting for user input - Progress HUB is in charge and is reading the progress queue - any other part wanting to react to a message like READY, .. This patch directly fixes the first two and adds a mechanism to register callbacks that will react to the third one. We (me and vpodzime) expect python-meh integration to use this to file exception reports from text mode installation. --- pyanaconda/ui/communication.py | 4 ++ pyanaconda/ui/tui/__init__.py | 3 +- pyanaconda/ui/tui/hubs/progress.py | 12 +++- pyanaconda/ui/tui/simpleline/base.py | 104 +++++++++++++++++++++++++++++++++-- pyanaconda/ui/tui/spokes/password.py | 5 +- 5 files changed, 117 insertions(+), 11 deletions(-) diff --git a/pyanaconda/ui/communication.py b/pyanaconda/ui/communication.py index 19e3a24..04bb512 100644 --- a/pyanaconda/ui/communication.py +++ b/pyanaconda/ui/communication.py @@ -37,9 +37,13 @@ hubQ = Queue.Queue() # _READY - [spoke_name, justUpdate] # _NOT_READY - [spoke_name] # _MESSAGE - [spoke_name, string] +# _INPUT - [string] +# _EXCEPTION - [exc] HUB_CODE_READY = 0 HUB_CODE_NOT_READY = 1 HUB_CODE_MESSAGE = 2 +HUB_CODE_INPUT = 3 +HUB_CODE_EXCEPTION = 4 # Convenience methods to put things into the queue without the user having to # know the details of the queue. diff --git a/pyanaconda/ui/tui/__init__.py b/pyanaconda/ui/tui/__init__.py index 83c2beb..8da9846 100644 --- a/pyanaconda/ui/tui/__init__.py +++ b/pyanaconda/ui/tui/__init__.py @@ -21,6 +21,7 @@ from pyanaconda import ui from pyanaconda.ui import common +from pyanaconda.ui import communication from pyanaconda.flags import flags import simpleline as tui from hubs.summary import SummaryHub @@ -170,7 +171,7 @@ class TextUserInterface(ui.UserInterface): """Construct all the objects required to implement this interface.
