# 2183:4420c8fadbf5 26-Feb-2006 Nathan Binkert <binkertn@umich.edu>

fix small python bug in database processing code

util/stats/db.py:
fix usage of hasattr


# 2014:7df693ff6fa4 19-Dec-2005 Nathan Binkert <binkertn@umich.edu>

Add a little bit of support to grab info for making graphs
without using the jobfile.

util/stats/db.py:
util/stats/profile.py:
Make it possible to send job as a string and to set the system
separately from the job.


# 2006:3ca085495c69 22-Nov-2005 Nathan Binkert <binkertn@umich.edu>

Major improvements in the graph output code. Mostly adding more
options, making existing options more visible and dealing with
holes in data better.

util/stats/barchart.py:
- move the options for BarChart to a base class ChartOptions so
they can be more easily set and copied.
- add an option to set the chart size (so you can adjust the aspect ratio)
- don't do the add_subplot thing, use add_axes directly so we can
affect the size of the figure itself to make room for the legend
- make the initial array bottom floating point so we don't lose precision
- add an option to set the limits on the y axis
- use a figure legend instead of an axes legend so we can put the legend
outside of the actual chart. Also add an option to set the fontsize of
the legend.
- initial hack at outputting csv files
util/stats/db.py:
don't print out an error when the run is missing from the database
just return None, the error will be print elsewhere.
util/stats/output.py:
- make StatOutput derive from ChartOptions so that it's easier to
set default chart options.
- make the various output functions (graph, display, etc.) take the
name of the data as a parameter instead of making it a parameter to
__init__. This allows me to create the StatOutput object with
generic parameters while still being able to specialize the name
after the fact
- add support for graph_group and graph_bars to be applied to multiple
configuration groups. This results in a cross product of the groups
to be generated and used.
- flush the html file output as we go so that we can load the file
while graphs are still being generated.
- make the proxy a parameter to the graph function so the proper system's
data can be graphed
- for any groups or bars that are completely missing, remove them from
the graph. This way, if we decide not to do a set of runs, there won't
be holes in the data.
- output eps and ps by default in addition to the png.
util/stats/profile.py:
- clean up the data structures that are used to store the function
profile information and try our best to avoid keeping extra data
around that isn't used.
- make get() return None if a job is missing so we know it was
missing rather than the all zeroes thing.
- make the function profile categorization stuff total up to 100%
- Fixup the x-axis and y-axis labels.
- fix the dot file output stuff.
util/stats/stats.py:
support the new options stuff for StatOutput


# 1934:84c12fdd57f9 21-Oct-2005 Nathan Binkert <binkertn@umich.edu>

Fix a couple of bug in the values() vector accessor

util/stats/db.py:
need to import the values function
util/stats/info.py:
it's just run


# 1929:fb189519cb06 21-Oct-2005 Nathan Binkert <binkertn@umich.edu>

Major cleanup of the statistics handling code

util/stats/db.py:
Build a result object as the result of a query operation so it is
easier to populate and contains a bit more information than just
a big dict. Also change the next level data into a matrix instead
of a dict of dicts.
Move the "get" function into the Database object. (The get function
is used by the output parsing function as the interface for accessing
backend storage, same interface for profile stuff.)
Change the old get variable to the method variable, it describes how
the get works, (whether using sum, stdev, etc.)
util/stats/display.py:
Clean up the display functions, mostly formatting.
Handle values the way they should be now.
util/stats/info.py:
Totally re-work how values are accessed from their data store.
Access individual values on demand instead of calculating everything
and passing up a huge result from the bottom.
This impacts the way that proxying works, and in general, everything
is now esentially a proxy for the lower level database. Provide new
operators: unproxy, scalar, vector, value, values, total, and len which
retrieve the proper result from the object they are called on.
Move the ProxyGroup stuff (proxies of proxies!) here from the now gone
proxy.py file and integrate the shared parts of the code. The ProxyGroup
stuff allows you to write formulas without specifying the statistics
until evaluation time.

Get rid of global variables!
util/stats/output.py:
Move the dbinfo stuff into the Database itself. Each source should
have it's own get() function for accessing it's data.
This get() function behaves a bit differently than before in that it
can return vectors as well, deal with these vectors and with no result
conditions better.
util/stats/stats.py:
the info module no longer has the source global variable, just
create the database source and pass it around as necessary


# 1881:fc205a7edd58 17-Sep-2005 Nathan Binkert <binkertn@umich.edu>

Totally re-work the way that jobfiles are done so there is more
information that can be used for other aspects of sending jobs.
New graphing output stuff with matplotlib.

util/pbs/job.py:
Shuffle code around and create the JobDir class which encapsulates
all of the functionality needed for making, organizing, and cleaning
a job directory.
Better status output
util/pbs/jobfile.py:
Majory re-working of the jobfile code.
A job file now consists of several objects that describe how
jobs should be run, it includes information about checkpoints,
and graphing.
util/pbs/send.py:
use the new jobfile code.
deal with the 15 character limit of pbs by truncating the name and
using the raj hack.
util/stats/db.py:
fix the __str__ function for nodes
provide __getitem__ for the Database class
util/stats/stats.py:
use the jobfile stuff to figure out what the proper naming
and organziation of the graphs should be.
move all output code to output.py, get rid of ploticus and use
matplotlib

Update for newer MySQLdb

util/stats/db.py:
Update for newer MySQLdb, the result of a blob in a query is an
array.array now, so we need to convert that to a string


# 1049:b175a798c8d4 09-Aug-2004 Nathan Binkert <binkertn@umich.edu>

Totally re-do/reorganize the python part of the statistics code
Make the database creation/removal/cleanup code use python
Make formulas work with the database
Add support to do some graphing, but needs more work
Still need to work on vectors, 2d vectors, dists and vectordists
