performance issues yq

[Morriz]

The 5 bats tests are not performing well. They should run under 5 seconds imo. Can this be optimized?

[0-sv]

Yes, I agree. It can be optimized, I wasn't sure if it was inside the scope in #203.

I have some ideas:

• Test everything from bootstrap.sh in one function, but this reduces test coverage.
• The true bottleneck is in what is being tested in bootstrap.sh. Currently, it's just one big script. We could write functions for the logic being tested and test those functions separately.
• The Github Actions runner could run on a dedicated server with more horsepower, since all the tests combined take a long time anyway.
• For some of the logic in bootstrap.sh, it's not quite DRY. I think the original intention was to setup everything for the first time, which makes sense. However, I'm also quite annoyed by the performance of this script, so I've just sym-linked the files I need into my otomi-values repo and now I never run it. Decoupling this script into multiple scripts that each have their own purpose would be great imo, and then they can be tested separately too, which will increase performance.

[Morriz]

Nah, you are overthinking it as the script only copies some files. Please understand that symlinking is for devs only, so no solution here. We need to time the operations. Is the file mount on the container inducing so much latency when it comes to copying? Instrument the code to show times with -x or something

[Morriz]

I think we have to look into decryption. Is that happening every call?

The latency in bin/bootstrap.sh occurs over here:

+ yq d - properties.toolsVersion
+ yq d /Users/sebastiaanverbeek/Projects/redkubes/dev/otomi-core/values-schema.yaml '**.required.'
+ yq d - properties.cluster
****LATENCY****
+ '[' /Users/sebastiaanverbeek/Projects/redkubes/dev/otomi-core '!=' /home/app/stack ']'
+ cp ./env/.vscode/values-schema.yaml .values/
+ echo 'Stored JSON schema at: ./env/.vscode/values-schema.yaml'

I added that line with 'LATENCY' of course. I don't know what to make of it though.

Reproduce it by running:

local targetPath="$ENV_DIR/.vscode/values-schema.yaml"                                                       
local sourcePath="$PWD/values-schema.yaml"
yq d $sourcePath '**.required.' | yq d - 'properties.toolsVersion' | yq d - 'properties.cluster' >$targetPath

Is it possible to follow the suggestion and downgrade yq even more? I'm not sure about the new version, maybe use that where appropriate

I see that mikefarah/yq#422 is solved in version 3.3.1
The otomi-tools is using version 3.3.2, why do you think that downgrading yq will improve performance?

[0-sv]

Well apparently there was a version where this wasn't an issue: "after downgrade to yq 2.4.1 --> zippy fast again (ie: 30s to parse yaml file in 3.x became sub second response time with 2.4.1)"

Well the issue isn't solved in 3.3.4 which is what I'm running:

yq version 3.4.1

Let's wait for #269 as discussed in Slack.

[Dunky13]

#271 Doesn't solve it, does the following command work:
yq r -j $sourcePath | jq "del(.. | .required?)" | jq "del( .properties.toolsVersion? )" | jq "del( .properties.cluster)" | yq r --prettyPrint -
Could use a little polishing, maybe combine the jq commands into one?
