Contributing to ansible-bender¶
Setting up your local development environment¶
Please make sure to follow bender’s installation process: https://github.com/ansible-community/ansible-bender#installation
For local development, you’ll need a few more packages. All of them are listed in setup.cfg:
To run bender from git, you need
setuptools_scm
Test suite is using
pytest
andflexmock
A lot of development automation is done in the Makefile so make sure that you have GNU make installed.
Since bender is so closely tight to podman and buildah, it works only on linux.
Tests¶
A good way to verify that everything works fine is to run the test suite in your local environment:
$ make check
PYTHONPATH=/home/me/path/to/ansible-bender PYTHONDONTWRITEBYTECODE=yes pytest-3 --cov=ansible_bender -l -v ./tests/
=============================== test session starts =====================================
platform linux -- Python 3.7.4, pytest-3.9.3, py-1.7.0, pluggy-0.8.1 -- /usr/bin/python3
cachedir: .pytest_cache
rootdir: /home/me/path/to/ansible-bender, inifile:
plugins: celery-4.3.0, cov-2.6.0

tests/functional/test_buildah.py::test_build_basic_image PASSED [ 3%]
tests/functional/test_buildah.py::test_build_basic_image_with_env_vars [....]
...
You can also run the test suite in a container:
$ make build-ab-img && make check-in-container
CI¶
Bender is using packit project for continuous integration.
Related files:
.packit.yaml — root config file for packit
.fmf/ — packit utilies `fmf <>`_ project under the hood and this dir is required for fmf to function
tests/ci.fmf — definition of tests to run in Packit’s CI System - Testing Farm
ci.yaml — Ansible playbook to set up the testing environment so bender’s test suite can run
Install the development version¶
You can install your development checkout like this:
$ cd local/git/checkout/of/bender/
$ pip3 install --user -e .
Run bender directly from git¶
It’s really easy:
$ PAYTHONPATH=/home/me/local/git/checkout/of/bender/ python3 -m ansible_bender.cli --help


Alexis Sanchez could make Inter return ahead of schedule
by FSA EditorThe start of Alexis Sanchez’s Inter career has been ruined by an ankle injury but the Chile star is progressing well in his recovery
Alexis Sanchez’s recovery from ankle surgery is on track and the Inter forward could return ahead of schedule.
Sanchez suffered a dislocated ankle and tendon damage while playing for Chile against Colombia in October.
The need to have an operation meant three months on the sidelines, curtailing the early stages of his loan stay at San Siro from Manchester United.
Inter’s head of medical services Piero Volpi told La Cuarta he is optimistic about Sanchez’s speed of recovery, with the 30-year-old aiming to resume work with a ball in the near future.
“It is a delicate injury, but the recovery is going very well, the deadlines are being met,” he said.
“Mid-January [is the return date] but we’ll see. Alexis could even come back a little earlier if all goes well.
“He has not yet done work with the ball, but we hope that in the next few days we will have news about it. Everything is going well.”
Sanchez scored on his only Serie A start for Inter, a 3-1 win at Sampdoria where he was later sent off, and has made four appearances overall for Antonio Conte’s side.
Inter’s first game of 2020 is away to Napoli in the league on January 5, while they host Atalanta a week later.

So there is really no issue having a huge amount of nodes, it would just get very expensive data wise?
and the process would get less reliable
jl777c04-Dec-18 01:19 PM
realisiically going over 64 notaries gives you very little benefit,but the logistics issues keep getting bigger
a lot of coins dont even have 64 full nodes for their network

blackjok3r04-Dec-18 01:35 PM
Yes agreed, I dont think even having 64 nodes is required tbh ... VBut being ablke to say, well you can have 128 nodes if you can afford it ... mightr help
jl777c04-Dec-18 01:43 PM
i assume 64 all over the place uint64_t
and really cant do much larger multisigs
Mylo04-Dec-18 02:56 PM
Exactly. 64 nodes already costs quite a lot in cap ex + labour.
64GB RAM, 1TB SSD each
jl777c04-Dec-18 03:15 PM
it is a tradeoff and I tried to select the details to have a good balance as possible
jorian04-Dec-18 05:03 PM
NN is centralised because you have to rely on a third party who determines for you what the longest chain is and that reorgs, which are a normal thing with blockchains, can't happen anymore(edited)
jl777c04-Dec-18 05:05 PM
plz ignore that all nodes in the network validate all notarizations, invalid notarizations are ignored
the "third party" is actually a set of normal nodes that are generating a consensus among themselves and this hash is then validated by all nodes.
claiming NN are centralized is like saying the tx you send out is centralized as only your node was involved in creating the tx
it is not the number of nodes involved in creating the tx that determines if it is decentralized, rather it is the number of nodes validating that does
2
maybe this is a subtle difference that non-tech people can overlook
2
jorian04-Dec-18 05:07 PM
but we need to rely on a third party so that is a centralizing factor
it's weird
Vertcoins argumentation
they rather let the chain die with honors than apply a somewhat less decentralized solution
jl777c04-Dec-18 05:12 PM
i bet they dont use DNS, or have a website either
such things are centralized
1
using a third party decentralized solution does not make it centralized, it just makes it a third party enabled solution. which is likely the actual reason. they dont want to rely on any third party as they wrote all their codebase without the help from any third party
@KomodoWorld @KomodoPlatform @VeriBlock My understanding is that KMD uses elected delegates (similar to block producers in EOS) that publish alt-chains to bitcoin's blockchain. Which, relative to VBK's piggybacking mechanism, is more centralized.
I asked to explain more and he did
"My understanding is that KMD uses elected delegates (similar to block producers in EOS) that publish alt-chains to bitcoin's blockchain. Which, relative to VBK's piggybacking mechanism, is more centralized. VBK enables any user to Proof-of-Proof mine, which is a way to spend market-competitive amounts of btc to insert an image of the Veriblock blockchain into the Bitcoin blockchain via a BTC transaction. And alt-chains will PoP mine to insert their chain-images onto the VBK chain."

"How Centralized is the dPoW notarization process?" ^^^
published about 20 minutes ago. may need an edit if inaccuracies exist.
Mylo04-Dec-18 06:30 PM
@KomodoWorld ^
jl777c04-Dec-18 06:47 PM
the writeup is good, but I would use a much clearer example to disprove the "dpow is centralized" nonsense
the basic logic that is used is that some "small" number of 64 nodes gets to create the notarization and thus it is more centralized than not having these special 64 nodes. This is false logic!
the level of decentralization is not based on how many nodes are participating in creating a transaction, but rather how many nodes are validating it. since all nodes validate all notarizations, it is as decentralized as any "centralized" tx that you make all by your self each time you create a transaction. Even though only one node is creating this transaction, it isnt centralized. the people claiming dpow is centralized is similar to claiming that anybody that sends a tx made on a single node is centralized.
Mylo04-Dec-18 06:56 PM
yep thanks james. i think this is a key point in veriblock's literature. one person sends a tx, and then it's validated everywhere
editing now
blackjok3r04-Dec-18 07:00 PM
wait veriblock has only 1 node that sends the tx to BTC ... and we have 13 ... so that means we are more decentralsied lol
absolutely nothing like masternodes or the dPoS delegates
yes all nodes validate, invalid notarizations are ignored. notary powers are intentionally limited to the bare minimum
just because people dont understand this, doesnt make them centralized
notarization is not creation
now, for KMD, the NN do get to easy mine, which is a totally different discussion
Mylo04-Dec-18 07:14 PM
jl777c04-Dec-18 07:14 PM
yes
Mylo04-Dec-18 07:15 PM
sweet. totally misunderstood final part. thanks for your patience!
jl777c04-Dec-18 07:22 PM
decentralization is hard to understand
it is easy to use it as a buzzword
but if you keep in mind that all nodes validating all transactions, this is the key to the decentralization as it avoids relying on any other node to tell you what happened
i think as long as this is the case, it is hard to argue that it isnt decentralized, let alone that it is centralized
blockhashes seen by all nodes, notarized by a subset and then validated by all nodes. compare that to a transaction that a single node makes and it validated by all nodes
it just boggles the mind at how dramatically things can be misunderstood, it might almost make one think it is an intentional misunderstanding
Mylo04-Dec-18 07:29 PM

James, quick Question, can you explain why sapling MPC should put to rest the XMR fud ?
i get a lot of fud that KMD is corrupted ( ZCash ceremony)
KomodoWorld05-Dec-18 10:01 AM
the new Sapling parameters were generated by over 170 people, so making 100% collusion or hijacking extremely unlikely
Acura05-Dec-18 10:03 AM
i get the argument that with now more people it is getting even worse
actionslacks05-Dec-18 10:04 AM

Alright05-Dec-18 10:06 AM
@KomodoWorld are sapling params from the "powers of TAU" MPC?
didn't think they were, thought that was something else entirely
Background Zcash’s zero-knowledge proofs rely on a set of public parameters which allow users to construct and verify private transactions. …
it says "For Zcash’s second set of public parameters, there are two distinct phases referred to as Powers of Tau and Sapling MPC"
Alright05-Dec-18 10:09 AM
so is powers of TAU params just not used at all?
KomodoWorld05-Dec-18 10:11 AM
I understand that powers of TAU was necessary first step to generate Sapling parameters
"In order to ensure the toxic waste does not come into existence, our team designed multi-party computation (MPC) protocols which allow multiple independent parties to collaboratively construct the parameters. These protocols have the property that, in order to compromise the final parameters, all of the participants would have to be compromised or dishonest.
To this date, Zcash has created two distinct sets of public parameters. The first ceremony happened in October 2016 just before the launch of Zcash Sprout. The second was generated in 2018 anticipating the Sapling network upgrade later that year.
In the Sprout MPC, all participants needed to commit to their share of the “toxic waste” in advance in order to protect against adaptive attacks. This meant that all of the participants needed to be available for the entire duration of the protocol, and nobody could abort without causing the entire protocol to abort. Participants needed to maintain custody of their hardware throughout the process, so this meant the ceremony could not scale beyond a handful of people.
The Sapling MPC allows participants join to the protocol, do their part and leave immediately. This allows the ceremony to scale to a large number of participants and take place over a longer period of time. It also decreases the surface area of attack for participants and avoids the need for expensive synchronization."
jl777c05-Dec-18 10:26 AM
my understanding is powers of tau was part of the sapling parameters process
anybody that claims that having more people involved makes it worse, when just having a single honest person makes it secure is ignoring some basic math
odds of collusion among 100% of participants is a monotonic increasing function with more participants, ie. the more participants the higher the odds for it to happen. with 100+ people, it seems a lot more unlikely than 6. not that having 6 people all colluding was anything that was very likely
@KomodoWorld @KomodoPlatform @VeriBlock Is it possible for the notaries to collude with a 51% attacker and notarize false data states? Want to emphasize whether it's possible not whether it is likely.
jl777c05-Dec-18 02:17 PM
since all notarizations are validated by all nodes, any invalid notarization will be ignored
it is not possible to create an invalid notarization that has any effect
i repeat: all nodes validate all notarizations
that is what makes dPoW decentralized
KomodoWorld05-Dec-18 02:19 PM
jl777c05-Dec-18 02:20 PM
if there is a 51% attacker and a valid notarization is made, then there can only be one notarized chain, so the attacker would stop his own attack
so the only thing is for the attacker to prevent notarizations via collusion. but the absence of notarizations is in itself an indication that something is wrong, either the chain is not reaching consensus, or notaries are somehow colluding to not notarize
which means the worst case of dPoW is that it degrades to the state things would be without dPoW at all
but with the ability to detect that something is wrong, even in this degraded state
1
Alright05-Dec-18 02:22 PM
if an exchange is using dpowconfs api, lack of notarizations will shut down their deposits
just thought I'd chime in there
jl777c05-Dec-18 02:23 PM
yes, which is the detection that something is wrong, even in the event notaries are corrupted
Alright05-Dec-18 02:23 PM
so even without dpow functioning, double spends aren't possible(edited)
if they use dpowconfs api that is
jl777c05-Dec-18 02:23 PM
it isnt dpowconfs api
it is just using the "confirmations" field from gettransaction, gettxout, etc
as long as normal methods are used to calculate confirmations, that is all that is needed
maybe some exchanges remember what block a tx came in and use that value, in such a case they need to add a call to gettxout or gettransaction and check the "confirmations" field
Alright05-Dec-18 02:25 PM
Just wanted to point out that even if notaries stop notarizing, a double spend is not possible
So if you could control all the notaries and have them all submit the same invalid chain-states, would the validating nodes know the difference? Sounds like the validating nodes are just accepting some threshold number of replicated chain-states across the notaries.
@KomodoWorld @KomodoPlatform @VeriBlock So if you could control all the notaries and have them all submit the same invalid chain-states, would the validating nodes know the difference? Sounds like the validating nodes are just accepting some threshold number of replicated ...
Is this reply accurate:
"Validating nodes have their version of blockchain too. If one controls all notary nodes they can submit any chain state they wish, but it will only be accepted by the rest of the network if it follows the consensus rules. Once a chain state is submitted to the network, even notaries can't re-org it. So what ever chainstate is submitted, there will only be one valid chain ever. So double spending is not possible."


Alphabet Inc. is an American multinational conglomerate headquartered in Mountain View, California. It was created through a corporate restructuring of Google on October 2, 2015, and became the parent company of Google and several former Google subsidiaries. The two founders of Google assumed executive roles in the new company, with Larry Page serving as CEO and Sergey Brin as president.
Alphabet's portfolio encompasses several industries, including technology, life sciences, investment capital, and research. Some of its subsidiaries include Google, Calico, Chronicle, GV, CapitalG, Verily, Waymo, X, Loon and Google Fiber. Some of the subsidiaries of Alphabet have altered their names since leaving Google and becoming part of the new parent company—Google Ventures becoming GV, Google Life Sciences becoming Verily and Google X becoming just X. Following the restructuring, Page became CEO of Alphabet and Sundar Pichai took his position as CEO of Google. Shares of Google's stock have been converted into Alphabet stock, which trade under Google's former ticker symbols of "GOOG" and "GOOGL". As of 2018, Alphabet is ranked #22 on the Fortune 500 rankings of the largest United States corporations by total revenue.
The establishment of Alphabet was prompted by a desire to make the core Google Internet services business "cleaner and more accountable" while allowing greater autonomy to group companies that operate in businesses other than Internet services.
