force:package:install --publishwait does not wait for package to become available

[jamesmelville]

Summary

We have a CI script which creates a new package and then directly installs it to an org. Often, this fails with the error:

ERROR: Encountered errors installing the package!,Installation errors: 
1) Invalid Package, Details: This package is not yet available. Please try again later or contact the package owner. 

This is despite our command using the force:package:install command with --publishwait argument

Steps To Reproduce:

1. Publish a new package version
2. Immediately attempt to install this package version in another org using force:package:install --publishwait

Expected result

Package gets installed once it's available to the org.

Actual result

Installation proceeds and then errors:

Waiting for the Subscriber Package Version ID to be published to the target org.
Waiting for the package install request to complete. Status = IN_PROGRESS
ERROR:  Encountered errors installing the package!,Installation errors: 
1) Invalid Package, Details: This package is not yet available. Please try again later or contact the package owner.

Additional information

This is already logged as a bug W-6015902 but I wanted to add it here to increase visibility and get an update on any fix.

When we run sfdx force:package:install it polls the SubscriberPackageVersion table:
SELECT Id, SubscriberPackageId FROM SubscriberPackageVersion WHERE Id='04t0000000000000000' AND InstallationKey ='null'

whilst displaying the message
Waiting for the Subscriber Package Version ID to be published to the target org.

When a record appears in this table, then the CLI thinks the package is available, and it starts installing:
Waiting for the package install request to complete. Status = IN_PROGRESS

But then fails pretty quickly with
ERROR: Encountered errors installing the package!,Installation errors: 1) Invalid Package, Details: This package is not yet available. Please try again later or contact the package owner.

When this happens, the InstallValidationStatus is normally PACKAGE_UNAVAILABLE. I think the CLI starts installing as soon as it finds a row in the SubscriberPackageVersion table, instead of also checking the status of that row.

I think the --publishwait argument should wait for the InstallValidationStatus to become "NO_ERRORS_DETECTED", and then start installation.

Workaround:
Instead of using --publishwait, implement your own polling mechanism which checks for status NO_ERRORS_DETECTED before you run sfdx force:package:install. Basic sh script requiring sfdx and jq:

WAIT_PACKAGE=true
POLL_LIMIT=30
POLL_COUNT=0
while [ $WAIT_PACKAGE ] && [ $POLL_COUNT -le $POLL_LIMIT ]
do
  sfdx force:data:soql:query --usetoolingapi \
                             --query "SELECT Id, SubscriberPackageId,InstallValidationStatus FROM SubscriberPackageVersion WHERE Id ='$INSTALL_VER'" \
                             --targetusername $TARGET_ORG \
                             --json > /tmp/workspace/packageStatus.json
  if [ $(jq -r '.result.records[0].InstallValidationStatus' /tmp/workspace/packageStatus.json) = "NO_ERRORS_DETECTED" ]
  then
    WAIT_PACKAGE=false
  else
    echo "Package status $(jq -r '.result.records[0].InstallValidationStatus' /tmp/workspace/packageStatus.json)"
    sleep 30
  fi
  POLL_COUNT=$(( POLL_COUNT+1 ))
done

You might see an output like this before the script continues:

Package status null
Package status null
Package status PACKAGE_UNAVAILABLE
Package status PACKAGE_UNAVAILABLE

@jamesmelville - this is expected to get fixed as a result of another piece of work that we plan to do in Summer '20. Cc @clairebianchi

[sfdc-db-gmail]

@jamesmelville - i believe this is fixed in v47 of CLI which is part of Winter '20 release. Please let us know if you are still experiencing this issue after Winter '20 rolls out over the next two weeks.

Hi @sfdc-db-gmail @clairebianchi

We just had this issue reoccur with the latest version of SFDX after we removed our workaround a few weeks ago. Unfortunately we didn't capture the logs, but I've switched log archiving back on in case it happens again. Are you aware of any regressions or is it possible there's a pending status that's been missed in the fix? Output and CLI version below:

$DEPLOY_TIMEOUT is set to 10 minutes and this failed after 2m34s.

[clairebianchi]

@jamesmelville Thank you for letting me know I will circle back with the Packaging PM

[sfdc-db-gmail]

@jamesmelville - My recommendations are (a) log a case and (b) join our trailblazer community https://sfdc.co/ulp to collaborate on this and other things related to packaging.

[jamesmelville]

Hi @clairebianchi and @sfdc-db-gmail - thanks for the input.

I'm a little confused now. For us this is an issue that occurs with 1GP managed packages, although I could imagine it affects packages in general. From my investigation above, it seemed to me that the failure was due to the CLI not understanding the documented statuses on the SubscriberPackageVersion object, and not really a bug with the platform.

Is this tracker the wrong place to log this issue, and if so why?

It seems to be a CLI issue, but this has been labelled "owned by another team", why is that?

How is the "Unlocked Packages" group relevant to this?

What is the correct route to logging these issue?

When this issue finally annoyed me enough to report it in February this year, I posted in the SalesforceDX group, which seems like a reasonable place to report it, and the issue was corroborated by another user, but this never got any response from Salesforce.

I also logged a case (21669907), which took 2 months, ~70 comments and multiple calls for me to get a bug logged after multiple attempts by the agent to tell me it was working as designed. Finally to get the bug logged I had to dig into the sfdx logs and work out was going on (as explained above) and describe this to the agent.

I'm generally very reticent to log cases because unless the problem is causing significant pain, dealing with support is a waste of all of our time, and for me posting issues in success rarely elicits helpful responses.

[clairebianchi]

@jamesmelville I am sorry to hear about your experience with support and our other channels for reporting issues. This repository is supported by the team that owns the CLI engine, we do not build all of the Force commands because we find it is best to have the experts in a given feature build the commands associated with that feature. This is why I passed your issue over the packaging team. I realize this is confusing and we are working internally to make this process better.

This channel also does not have an SLA and often takes a while because I am trying to find the right person/team to take a look at your issue.

I am going to reopen this issue here, so I have more visibility into it and can follow the progress. If you did open a case, please add the case number here and I will follow up with support myself.

@sfdc-db-gmail can you please review @jamesmelville comment above?

[jamesmelville]

@clairebianchi Thanks for your explanation and for reopening this.
I think we've completed about ~30 installations since the Winter 19 rollout and only one has failed in the manner I described, I think we had about a 50% failure rate when I reported the issue, so thank you for the improvement.
I've had a look at the logs and can see the CLI is querying the InstallValidationStatus. I'll keep an eye out for any further occurrences and let you know, although I'm not sure the log files will give us useful information anyway.

From the logs I can see that the SubscriberPackageVersion table was being polled multiple times,
SELECT Id, SubscriberPackageId, InstallValidationStatus FROM SubscriberPackageVersion WHERE Id ='04t1r0000000000000' AND InstallationKey ='null'
and at some point it decided it was ready to continue with installation because it queried some other fields:
SELECT RemoteSiteSettings, CspTrustedSites FROM SubscriberPackageVersion WHERE Id ='04t1r0000000000000' AND InstallationKey ='null'
It then attempted to install and failed with
[\n '\\u001b[1mERROR running force:package:install: \\u001b[22m',\n '\\u001b[31mInstallation errors: \\u001b[39m\\n' +\n '\\u001b[31m1) Invalid Package, Details: This package is not yet available. Please try again later or contact the package owner.\\u001b[39m'\n]

Unfortunately the logs don't include the responses to queries. @clairebianchi would it help for me to redact the log files and post here or can I share directly somewhere? I'm on log level trace which I think is the highest level (fatal doesn't give me much output). We've probably done 30-40 installations (ones which are triggered directly after package creation) since the last time this happened.

This is the same issue as #1895 which has been fixed.
