Issues with Git Pull

[michael-rust]

We consistently see an issue where we start a git pull from the IRIS for Health homepage and there is no indication if the pull finished successfully or with errors.

When we look at the classes that were pulled in they are in an uncompiled state.

See screenshots attached.

IRIS version: IRIS for UNIX (Red Hat Enterprise Linux 9 for ARM64) 2024.1 (Build 263U) Wed Mar 13 2024 15:32:09 EDT [Health:7.2.0] Git package version: 2.4.1 GitPullIssues.docx

@isc-tleavitt notes on aspects of this:

• [x] Handle leading .../ in output from git commands
• [x] Double check handling of load/compilation errors from WebSocket perspective
• [x] Review possible issues with preview output being absent in HCC environment - we need to make sure there's always some output even if nothing has changed.

@michael-rust thanks for filing this, helpful to have as a reminder.

Can you see if the git pull records anything in the application error log?

This may be related in part to #457 (re: the uncompiled state).

[michael-rust]

Yes, there was this error: " 127 Pull+1^SourceControl.Git.API.1". The full application log is attached. Applog.docx

Ahh - this is highly relevant.

Can you try reinstalling git-source-control via standard zpm "install git-source-control"? I think you have a snapshot of 2.4.1 prior to actual release.

[michael-rust]

Is there a way to confirm the install? When I go to the git settings it says package version: 2.4.1

[isc-tleavitt]

@michael-rust good question - ultimately it's a matter of our practices in this git repo; we haven't generally put a -SNAPSHOT designation on the main branch between releases so there isn't any delineation between something-that-could-be 2.4.1 (installed via zpm "load https://github.com/intersystems/git-source-control") and 2.4.1 itself.

If you zpm "install git-source-control" you'll definitely get the real 2.4.1. Better answers are coming eventually in IPM itself.

[michael-rust]

Okay sounds good. I'll report back the next time we do a pull. Thanks for the quick responses.

[isc-tleavitt]

I'll keep an eye out - thank you for nudging on this publicly!

Hi Tim,

After installing the latest package we're still seeing the following issues with the git pull:

1. No preview is shown before the pull
2. No indication if the pull was successful or not
3. Imported classes are uncompiled.

The issues listed above only happen sometimes, other times it all works perfectly, which I know is a troubleshooting nightmare.

[isc-tleavitt]

Root cause: /isc/studio/usertemplates is tied to %SYS. %SYS (via IRISSYS) had an old version of %zpkg.isc.sc.git.Socket The user namespace in question had a newer/updated version of %zpkg.isc.sc.git.Socket mapped to a nondefault database, as was the SourceControl package. %zpkg.isc.sc.git.Socket from IRISSYS (which was stale) was calling the wrong version. Solution: package-map %zpkg.isc.sc.git in %SYS to the user code database.

[isc-tleavitt]

This mapping issues most likely explain the problems with indication of pull success as well, but it would be worth double checking the error handling to make sure we're not just relegating useful output in the application error log in event of a serious failure.

There appears to be a secondary issue with preview output being displayed (from testing in my own HCC environment) - need to investigate this, and specifically to make sure that there's always some output. The issue in that environment could also be similar depending on the mapping techniques being used there. (This still needs triage.)

There is another cause for files not being loaded (!) or compiled independent of #457: with a large set of files changed, some in subfolders common among changes, if output has .../ it isn't processed properly. We need to update this to properly interpret as a relative folder.

[isc-tleavitt]

With improved logging (from work in progress) the .../ issue could end up looking like:
