This is all minor stuff: unreachable debug code (that should be commented-out
instead of in an 'if False:' block), unnecessary 'pass' and 'global'
statements, redundantly-initialized variables. No behavior changes. Nothing
here was actually broken, it just looked suspicious to the static analysis at
https://lgtm.com/projects/g/tahoe-lafs/tahoe-lafs/alerts/?mode=list .

On the branch meejah:1382.markberger-rewrite-rebase.6 as
per review
Remove old hypothesis tests
Fix allmydata.test.cli.test_cli.Errors.test_get
this was broken due to differing share placements
whereas we need to allow this.
Fix test_5_overdue_immutable
This change makes the test not depend on the value
of PYTHONHASHSEED.
Revert "Fix test_5_overdue_immutable"
This reverts commit 5f3696d9a53e7df8781a2c463c7112282397cd69.
fix test to actually hang the first 5 *servers*
sort keys for stable output
use file-context-managers
remove probably-unneeded assert (that fails sometimes)
another non-deterministic test?
correctly calculate happiness
guard with except
fix tests, and happiness calculation
remove debug
fix placements to None
happiness calc shouldn't have to filter None
WIP fixing some tests etc
Comment out all debug print statements
Add hypothesis tests for the old servers of happiness implementation
Attempt to speed up meejah's servers of happiness
WIP
Fix test_calc_happy
WIP
refactor hypothesis to be 'pytest style' and add another one
get rid of 'shares->set(1 thing)' in generate_mappings return
Add a unittest hypothesis came up with
fix tests since we return peers, not sets-of-1-peer
add more debug
add a unit-test that's like test_problem_layout_ticket_1128
fix bug
add a note
fix utest
unit-test for bigger numbers
re-insert markberger code for testing
results of pairing with david
unit-test for happiness calculation
unused function
put old servers_of_happiness() calculation back for now
test for calculate_happiness
remove some redundant functions
Add comments 10 and 8 from the servers of happiness spec
Fix bug in _filter_g3 for servers of happiness
Remove usage of HappinessUpload class
here we modifying the PeerSelector class.
we make sure to correctly calculate the happiness value
by ignoring keys who's value are None...
Remove HappinessUpload and tests
Replace helper servers_of_happiness
we replace it's previous implementation with a new
wrapper function that uses share_placement
This is a change I've wanted to make for many years, because when we get
to HTTP-based servers, we won't have tubids for them. What held me back
was that there's code all over the place that uses the serverid for
various purposes, so I wasn't sure it was safe. I did a big push a few
years ago to use IServer instances instead of serverids in most
places (in #1363), and to split out the values that actually depend upon
tubid into separate accessors (like get_lease_seed and
get_foolscap_write_enabler_seed), which I think took care of all the
important uses.
There are a number of places that use get_serverid() as dictionary key
to track shares (Checker results, mutable servermap). I believe these
are happy to use pubkeys instead of tubids: the only thing they do with
get_serverid() is to compare it to other values obtained from
get_serverid(). A few places in the WUI used serverid to compute display
values: these were fixed.
The main trouble was the Helper: it returns a HelperUploadResults (a
Copyable) with a share->server mapping that's keyed by whatever the
Helper's get_serverid() returns. If the uploader and the helper are on
different sides of this change, the Helper could return values that the
uploader won't recognize. This is cosmetic: that mapping is only used to
display the upload results on the "Recent and Active Operations" page.
I've added code to StorageFarmBroker.get_stub_server() to fall back to
tubids when looking up a server, so this should still work correctly
when the uploader is new and the Helper is old. If the Helper is new and
the uploader is old, the upload results will show unusual server ids.
