I've sent this before, this is an updated version with several bugfixes and improvements. Its a major change but one I think people will like overall as I hear a lot of complaints about the verbose console messages. v0 never got complaints so I will merge this fairly quickly unless there are objections.
--- On terminals which support it, add summary information to the end of the build output about the number of tasks currently running and how many tasks we've run so far. This provides a summary at a glace of what the current state of the build is and what the build is currently doing which is lacking in the current UI. Also disable echo of characters on stdin since this corrupts the disable, particularly Crtl+C. The "waiting for X tasks" code can be merged into this code too since that is only useful on interactive terminals and this improves the readability of that output too. Improvements since v0: * The tasks are ordered in execution order. * The display is only updated when the list of tasks changes or there is output above the footer. * Errors early in the init process don't corrupt the terminal * Running task x of y and package messages are suppressed from the console Signed-off-by: Richard Purdie <[email protected]> --- diff --git a/bitbake/lib/bb/ui/knotty.py b/bitbake/lib/bb/ui/knotty.py index 14989d4..4a7e6b9 100644 --- a/bitbake/lib/bb/ui/knotty.py +++ b/bitbake/lib/bb/ui/knotty.py @@ -72,6 +72,26 @@ def pluralise(singular, plural, qty): def main(server, eventHandler): + cuu = None + stdinbackup = None + + if interactive: + import curses + import termios + import copy + try: + fd = sys.stdin.fileno() + stdinbackup = termios.tcgetattr(fd) + new = copy.deepcopy(stdinbackup) + new[3] = new[3] & ~termios.ECHO + termios.tcsetattr(fd, termios.TCSADRAIN, new) + curses.setupterm() + ed = curses.tigetstr("ed") + if ed: + cuu = curses.tigetstr("cuu") + except: + cuu = None + # Get values of variables which control our output includelogs = server.runCommand(["getVariable", "BBINCLUDELOGS"]) loglines = server.runCommand(["getVariable", "BBINCLUDELOGS_LINES"]) @@ -115,8 +135,56 @@ def main(server, eventHandler): errors = 0 warnings = 0 taskfailures = [] + main.footer_present = False + main.lastpids = [] + + def updateFooter(): + if not cuu: + return + activetasks = helper.running_tasks + failedtasks = helper.failed_tasks + runningpids = helper.running_pids + if main.footer_present and (main.lastpids == runningpids): + return + if main.footer_present: + clearFooter() + if not activetasks: + return + lines = 1 + tasks = [] + for t in runningpids: + tasks.append("%s (pid %s)" % (activetasks[t]["title"], t)) + + if shutdown: + print("Waiting for %s running tasks to finish:" % len(activetasks)) + else: + print("Currently %s running tasks (%s of %s):" % (len(activetasks), helper.tasknumber_current, helper.tasknumber_total)) + for tasknum, task in enumerate(tasks): + print("%s: %s" % (tasknum, task)) + lines = lines + 1 + main.footer_present = lines + main.lastpids = runningpids[:] + + def clearFooter(): + if main.footer_present: + lines = main.footer_present + sys.stdout.write(curses.tparm(cuu, lines)) + sys.stdout.write(curses.tparm(ed)) + main.footer_present = False + + class InteractConsoleLogFilter(logging.Filter): + def filter(self, record): + if record.levelno == format.NOTE and (record.msg.startswith("Running") or record.msg.startswith("package ")): + return False + clearFooter() + return True + + if interactive: + console.addFilter(InteractConsoleLogFilter()) + while True: try: + updateFooter() event = eventHandler.waitEvent(0.25) if event is None: if shutdown > 1: @@ -126,12 +194,6 @@ def main(server, eventHandler): if isinstance(event, bb.runqueue.runQueueExitWait): if not shutdown: shutdown = 1 -
