If you're looking to find the latest console log repeatedly it can be a bit
tedious - let's just create a symlink just as we do with other logs to
make it easy to find.

Since we're going to make some minor extensions to it, it makes sense to
bring in the latest version of python-progressbar. Its structure has
changed a little but the API hasn't; however we do need to ensure our
overridden _needs_update() function's signature in BBProgress() matches
properly.

-"""Text progressbar library for python.
-
-This library provides a text mode progressbar. This is typically used
-to display the progress of a long running operation, providing a
-visual clue that processing is underway.
-
-The ProgressBar class manages the progress, and the format of the line
-is given by a number of widgets. A widget is an object that may
-display diferently depending on the state of the progress. There are
-three types of widget:
-- a string, which always shows itself;
-- a ProgressBarWidget, which may return a diferent value every time
-it's update method is called; and
-- a ProgressBarWidgetHFill, which is like ProgressBarWidget, except it
-expands to fill the remaining width of the line.
-
-The progressbar module is very easy to use, yet very powerful. And
-automatically supports features like auto-resizing when available.

-    ...    # do something
-    ...    pbar.update(i+1)

-    You can also use a progressbar as an iterator:

-    >>> for i in progress(some_iterable):
-    ...    # do something
-    ...
-
-    But anything you want to do is possible (well, almost anything).
-    You can supply different widgets of any type in any order. And you
-    can even write your own widgets! There are many widgets already
-    shipped and you should experiment with them.
-
-    The term_width parameter must be an integer or None. In the latter case
-    it will try to guess it, if it fails it will default to 80 columns.
-
-    When implementing a widget update method you may access any
-    attribute or function of the ProgressBar object calling the
-    widget's update method. The most important attributes you would
-    like to access are:
-    - currval: current value of the progress, 0 <= currval <= maxval
-    - maxval: maximum (and final) value of the progress
-    - finished: True if the bar has finished (reached 100%), False o/w
-    - start_time: the time when start() method of ProgressBar was called
-    - seconds_elapsed: seconds elapsed since start_time
-    - percentage(): percentage of the progress [0..100]. This is a method.
-
-    The attributes above are unlikely to change between different versions,
-    the other ones may change or cease to exist without notice, so try to rely
-    only on the ones documented above if you are extending the progress bar.

+"""Text progress bar library for Python.
+
+A text progress bar is typically used to display the progress of a long
+running operation, providing a visual cue that processing is underway.
+
+The ProgressBar class manages the current progress, and the format of the line
+is given by a number of widgets. A widget is an object that may display
+differently depending on the state of the progress bar. There are three types
+of widgets:
+ - a string, which always shows itself
+
+ - a ProgressBarWidget, which may return a different value every time its
+   update method is called
+
+ - a ProgressBarWidgetHFill, which is like ProgressBarWidget, except it
+   expands to fill the remaining width of the line.
+
+The progressbar module is very easy to use, yet very powerful. It will also
+automatically enable features like auto-resizing when the system supports it.

+
+    A common way of using it is like:

+    ...    # do something
+    ...    pbar.update(i+1)

+    You can also use a ProgressBar as an iterator:
+    >>> progress = ProgressBar()
+    >>> for i in progress(some_iterable):
+    ...    # do something
+    ...
+
+    Since the progress bar is incredibly customizable you can specify
+    different widgets of any type in any order. You can even write your own
+    widgets! However, since there are already a good number of widgets you
+    should probably play around with them before moving on to create your own
+    widgets.
+
+    The term_width parameter represents the current terminal width. If the
+    parameter is set to an integer then the progress bar will use that,
+    otherwise it will attempt to determine the terminal width falling back to
+    80 columns if the width cannot be determined.
+
+    When implementing a widget's update method you are passed a reference to
+    the current progress bar. As a result, you have access to the
+    ProgressBar's methods and attributes. Although there is nothing preventing
+    you from changing the ProgressBar you should treat it as read only.
+
+    Useful methods and attributes include (Public API):
+     - currval: current progress (0 <= currval <= maxval)
+     - maxval: maximum (and final) value
+     - finished: True if the bar has finished (reached 100%)

+     - seconds_elapsed: seconds elapsed since start_time and last call to

From: Paul Eggleton @ 2016-06-13  2:52 UTC (permalink / raw)
  To: bitbake-devel

For long-running tasks where we have some output from the task that
gives us some idea of the progress of the task (such as a percentage
complete), provide the means to scrape the output for that progress
information and show it to the user in the default knotty terminal
output in the form of a progress bar. This is implemented using a new
TaskProgress event as well as some code we can insert to do output
scanning/filtering.

Any task can fire TaskProgress events; however, if you have a shell task
whose output you wish to scan for progress information, you just need to
set the "progress" varflag on the task. This can be set to:
 * "percent" to just look for a number followed by a % sign
 * "percent:<regex>" to specify your own regex matching a percentage
   value (must have a single group which matches the percentage number)
 * "outof:<regex>" to look for the specified regex matching x out of y
   items completed (must have two groups - first group needs to be x,
   second y).
We can potentially extend this in future but this should be a good
start.

Part of the implementation for [YOCTO #5383].

Add a class to help report progress in a task that consists of multiple
stages, some of which may have internal progress (do_rootfs within
OpenEmbedded is one example). Each stage is weighted to try to give
a reasonable representation of progress over time.

Part of the implementation for [YOCTO #5383].

Implement progress reporting support specifically for the fetchers. For
fetch tasks we don't necessarily know which fetcher will be used (we
might initially be fetching a git:// URI, but if we instead download a
mirror tarball we may fetch that over http using wget). These programs
also have different abilities as far as reporting progress goes (e.g.
wget gives us percentage complete and rate, git gives this some of the
time depending on what stage it's at). Additionally we filter out the
progress output before it makes it to the logs, in order to prevent the
logs filling up with junk.

At the moment this is only implemented for the wget and git fetchers
since they are the most commonly used (and svn doesn't seem to support
any kind of progress output, at least not without doing a relatively
expensive remote file listing first).

Line changes such as the ones you get in git's output as it progresses
don't make it to the log files, you only get the final state of the line
so the logs aren't filled with progress information that's useless after
the fact.

Part of the implementation for [YOCTO #5383].

In addition to the "currently running n tasks (x of y)" message, show a
progress bar for another view on how much of the build is left. We have
to take care to reset it when moving from the scenequeue to the
runqueue, and explicitly don't include an ETA since not all tasks take
equal time and thus it isn't possible to estimate the time remaining
with the information available.

Quiet output mode disables printing most messages (below warnings) to
the console; however these messages still go to the console log file.
This is primarily for cases where bitbake is being launched
interactively from some other process, but where full console output is
not needed.

Because of the need to keep logging all normal events to the console
log, this functionality was implemented within the knotty UI rather
than in bb.msg (where verbose mode is implemented). We don't currently
have a means of registering command line options from the UI end, thus
the option actually has to be registered in main.py regardless of the
UI, however I didn't feel like it was worth setting up such a mechanism
just for this option.

* [PATCH 09/10] runqueue: add ability to enforce that tasks are setscened

Add the ability to enter a mode where only a specified whitelist of
tasks can be executed outright; everything else must be successfully
provided in the form of a setscene task (or covered by a setscene task).
Any setscene failure outside of the whitelist will cause the build to
fail immediately instead of running the real task, and any real tasks
that would execute outside of the whitelist cause an immediate build
failure when it comes to executing the runqueue as well.

The mode is enabled by setting BB_SETSCENE_ENFORCE="1", and the
whitelist is specified through BB_SETSCENE_ENFORCE_WHITELIST, consisting
of pn:taskname pairs. A single % character can be substituted for the pn
value to match any target explicitly specified on the bitbake command
line. Wildcards * and ? can also be used as per standard unix file name
matching for both pn and taskname.

Part of the implementation of [YOCTO #9367].

When "Preparing RunQueue" shows up you can expect to wait up to 30
seconds while it works - which is a bit long to leave the user waiting
without any kind of output. Since the work being carried out during this
time is divided into stages such that it's practical to determine
internally how it's progressing, replace the message with a progress
bar.

Actually what happens during this time is two major steps rather than
just one - the runqueue preparation itself, followed by the
initialisation prior to running setscene tasks. I elected to have the
progress bar cover both as one (there doesn't appear to be much point in
doing otherwise from a user perspective). I did however describe it as
"initialising tasks".

I appreciate the difficulty in figuring some of this out and the
changes look quite neat on the most part. I am however very worried by
the above from a code maintenance standpoint.

If for example I add or remove a step in runqueue, how do I know where
in this array to make a change? How do I calculate what the new
weighting should be?

I did wonder if next_stage() should pass the number instead, that way
at least the call site would be clearer. It doesn't solve the problem
of knowing how many steps there are, or what these weights mean or how
to recalculate them in the future.

Any thoughts on that?

Cheers,

Richard

Actually with the current patchset it's pretty easy. Just temporarily specify 
debug=True to the reporter when constructing and it will print out the list of 
weightings (based on timing each stage) when finish() is called, along with a 
map of the weightings to the lines where next_stage() was called. (Perhaps if 
we'd want a comment to that effect for anyone editing this code.)

I guess you could do it that way; in the way I'd structured the code earlier 
it wouldn't have been practical but now that next_stage() must be called 
before every stage, it could be done. The trouble though is that then if you 
want to set them all at once (as you often would, since they are relative) you 
will have to go to each line and update it instead of just changing the list 
passed to the constructor, so I'm not convinced that's an improvement.

Cheers,
Paul

I think a comment in there about this would be helpful as it isn't
clear how to handle this. What does it do in the case you have a next()
call without a weight? Will that give a warning?

OK, I'll add one - I need to rebase this patchset anyway.

wget: unrecognized option '--show-progress'

Turns out wget on Ubuntu 14.04 (wget 1.15) doesn't support this option.

Turns out it was introduced in 1.16. Sigh...

I will try to figure out what we can do with this. Worst case I suppose we 
could run wget once to determine the version and just disable progress 
reporting if it's too old.

Cheers,
Paul
