Zitat von John Ralls <jra...@ceridwen.us>:
I estimate the effort in the following way:
(AVG_of_branching * number_of_functions *
time_to_test_one_branch_in_minutes)/(minutes_in_hour *
number_of_working_days).
Avg of branching in function is something that i get by dividing
code complexity number (3729) by number of functions, (...)
Like I said, you're the only one at this point who knows how fast
you can code. But your calculations are a bit, um, overly precise.
I agree with John on the "overly precise" bit. However, I don't think
this is a problem at this point in time at all.
For your project we can simply confirm that the goal of "full unittest
coverage of all of libqof" is too ambitious for GSoC. Doing the
complexity estimations is one out of several useful ways to tell up
front whether the task can or cannot be done, and it is also a valid
part of such a GSoC project. Thanks for the numbers :-)
I agree with John that you should pick a useful subset of libqof, and
this way, the project will surely fit inside GSoC again.
As for how to find the "useful subset": I've created a list of
libqof's symbols which are used from the rest of gnucash (attached)
with usage count. This list of used symbols has 346 entries, whereas
the list of libqof's exported symbols contains 524 entries. This is
already a strong indication that libqof might contains 524-352=172
functions which are unused throughout gnucash. Following my remarks in
my last message I'd say almost all of those 176 unused functions
should be removed anyway, which means your project size might already
reduce into useful ranges.
Note: I've done this for *symbols*. A symbol corresponds to an
exported function. The libqof code might provide more functions to the
rest of gnucash which are still used but are not a symbol. For
example, all macros and all enums are provided to the rest of gnucash
but are not symbols. Similar for inline functions even though I don't
know whether we actually use those. The details for my research is
shown below.
For now, I'd propose you should go ahead in writing up your
application, and we can just confirm we will find a useful subset of
libqof to be covered that will be doable within GSoC.
Regards,
Christian
