SAFE Network Dev Update - March 26, 2020

Dunno - still at my tea - the pasta was a bit al dente so it took a long time to chew

I’ll get onto it soon, promise…

I ran into an issue where the newly created account was initially unable to read its balance. This was repeatable but on the third attempt, I got the expected behaviour. I have a long running test job (50k iterations of putting 3Kb to the vaults) so it may be difficult to parse the logs to track this down @bochaco @joshuef @StephenC @lionel.faber - do you still want them?

I need to create a new SafeKey so that I have a URL to attempt to transfer funds into
Q. Why does the original key created not have a URL? Am I missing something here? How can that account receive new funds?

Southside · March 29, 2020, 8:54pm

Returning to the account which generated the first error above. Wait 10 mins and try again - success!!!

so now I have multiple accounts, two of which have SafeKey URLs I can attempt a transfer.
In one terminal

and in the other terminal

so I created a wallet at safe://hbyyyybm8exc6higktxpwgeie15jkz893ubgcoyzz14z6ripwtwi35odx8 with 500 coins and then transferred another 150 coins giving the expected balance of 650.

Took a bit of messing around but the basic mechanism is there OK, now bright guys like @JimCollinson are working to put a nice UI on that so we are sheilded from all these ugly long numbers.

KafkaLee · March 30, 2020, 4:18am

great! curious… how long does it take to transfer ? can u approximately measure it?
Ah, I suceesfully launched baby-fleming with sudo command.

sudo safe vault run-baby-fleming

hmm…

felixmc · March 30, 2020, 8:07am

Clean UI, I like it!

Toivo · March 30, 2020, 10:23am

Memory 7.7G
Swap 7.9G
Disk space about 180G. I could possibly free more to gain up to 300G or so.

Ubuntu 16.04
HP-ProBook-450-G5
Intel® Core™ i5-8250U CPU @ 1.60GHz × 8
Intel® UHD Graphics 620 (Kabylake GT2)

I don’t have any other use for this machine, so no problem if it jams. How should I proceed?

I prefer something that would not require long attention spans from me, but then again this machine can hiss and humm for hours without problems.

Southside · March 30, 2020, 10:26am

very quick - but this is all within my PC - no actual network traffic involved so I doubt this really means anything at all

willie@gagarin:~$ time safe keys transfer 250  --from 87c9ac4827c5542dd2a6d994ab007c0dfd2fe19551ac89c5780550321030ea54 --to safe://hbyyyybm8exc6higktxpwgeie15jkz893ubgcoyzz14z6ripwtwi35odx8
Success. TX_ID: 9125324247792691158

real	0m0.197s

And on the other terminal I get the familiar random errors - but keep trying…

And we see the balance increases by 250 from 650 to 900

Southside · March 30, 2020, 10:42am

180 Gb is fine for now, @dirvine said there is an artificial limit on vault size meantime. Memory should be OK.

Make sure you have the latest versions of the software as mentioned at the top of the thread and then read through https://github.com/maidsafe/safe-api/blob/master/safe-cli/README.md

Once you have tried out each of the commands and their various options, you can fork or just copy
change-nappies/run-new-network.sh at master · willief/change-nappies · GitHub change-nappies/test_and_report.sh at master · willief/change-nappies · GitHub

which should issue the commands in the correct order to set up your network with logging and then run batches of tests. @davidpbrown also has scripts to run tests with random upload sizes.

Please ask for help at any time you feel uncertain about anything. This works both ways, by answering your help requests I gain knowledge too as I have to think about things from your point of view with your environment.

Make sure you have plenty room in /tmp, some people put /tmp on its own partition so if something writes zillions of data to /tmp, only that partition fills up , not your whole disk.
Tip: I often put /var/log on its own partition on a server for the same reason. If some log gets very chatty, then its only the logging stops, not the server.

Toivo · March 30, 2020, 10:54am

How do I do this?

It seems I managed to install CLI, but should I still get the Vault and something else separately? There is a thread in the forum about latest releases, but it is of no help.

Also, when I tried:

safe vault install
It returned:

safe: error while loading shared libraries: libssl.so.1.1: cannot open shared object file: No such file or directory

Southside · March 30, 2020, 10:58am

try sudo apt-get install openssl

sudo apt-get install build-essential would probably help too if/when you get around to building packages

Toivo · March 30, 2020, 11:06am

Did both of those and they seemed to do what they were supposed to, but still the same error when trying to install vault.

I appreciate a lot your help here.

davidpbrown · March 30, 2020, 11:23am

Google suggests

add the path /usr/local/openssl/lib to /etc/ld.so.conf and run ldconfig

Noting that was a solution against an older Ubuntu 16.04 reasons to stay up to date.

Southside · March 30, 2020, 11:34am

@Toivo Once you have done as @davidpbrown suggests above, if you still have bother check by running

sudo updatedb ← may take a couple of mins
then
locate libssl.so.1.1

davidpbrown · March 30, 2020, 11:48am

My thought on testing complexity is

Current OS’
Legacy OS’
Build from source

I stick to 1.

Toivo · March 30, 2020, 12:00pm

Sorry, I don’t understand what this means:

How to add that path to that other path? Copy the stuff inside that “lib” folder to the “ld.so.conf” folder?

davidpbrown · March 30, 2020, 12:13pm

I would expect that is a config file you can edit with
sudo nano /etc/ld.so.conf
…adding /usr/local/openssl/lib

Southside · March 30, 2020, 12:25pm

/etc/ld.so.conf may be very sparse, mine only consists of

so make yours look like

then ctrl-x, and y to confirm the save.

EDIT: yes I know there is a more “correct” way to do it but that should get it working for now.
Perhaps you should consider an upgrade to 18.04, despite what has been said, we are likely to learn more from you using a somewhat lower spec laptop then what we learn from an OS that only has one more years support left. Whats the consensus on this folks?

davidpbrown · March 30, 2020, 12:38pm

Obviously this is a forum for SAFE, not a cure all for OS oddities that are not SAFE specific.
Where it’s trivial, we can give pointers but there are better options for known problems elsewhere…

Southside · March 30, 2020, 12:43pm

True but lets help out where we can

@mods - do you want to move this elsewhere?
