Fix GCP step logging

[adtygan]

Describe changes

The issue arises because GCS artifacts are immutable Stack Overflow thread. To fix the issue, I suggest a fix based on @strickvl 's idea mentioned below

Alex Strick van Linschoten's Idea

Consider using the logging.StreamHandler facility to temporarily write logs to the remote file (GCS, S3, etc.). Here's an example:

import logging
import fsspec

f = fsspec.open("gs://<<my_gcs_bucket>>/test_log.log", "w")
with f as of:
    log_handler = logging.StreamHandler(of)
    logger = logging.getLogger()  # Root logger
    logger.addHandler(log_handler)
    for i in range(0, 5000):
        logger.warning(f"I'm log line #{i}")
    logger.removeHandler(log_handler)

This approach could fit nicely in the StepLogsStorageContext class.

My Solution

Set buffer size to sys.maxsize and copy the existing contents of the log file to the buffer. This prevents the triggering of the part of code that appends buffer contents to log file once buffer is full and flushes buffer. (reference)

Code to test the change:

Please use GCS stack

import gcsfs
from zenml.client import Client
from zenml.logging.step_logging import StepLogsStorage, StepLogsStorageContext

client = Client()
_ = client.active_stack

TEST_FILE="gs://<<my_gcs_bucket>>/test.txt"

with StepLogsStorageContext(logs_uri=TEST_FILE) as log_storage:
    for i in range(0,10):
        print(f"I'm log line #{i}")

fs = gcsfs.GCSFileSystem()

with fs.open(TEST_FILE, 'r') as f:
    all_of_it = f.read()

print('Final Contents:')
print(all_of_it)

In the realm of code, where logs do sprawl,
A rabbit hopped, aiming to enthrall.
With messages tamed, and errors so few,
Through cloud and through file, our insights grew.

Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai generate interesting stats about this repository and render them as a table.
  • @coderabbitai show all the console.log statements in this repository.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

@adtygan there's a linting error that needs fixing

[adtygan]

@strickvl , I ran the below commands before I made the PR

zenml integration install gcp 
pip install click~=8.0.3
mypy --install-types

After that I ran

bash scripts/format.sh
bash scripts/run-ci-checks.sh >> .local/run-ci-checks.log

For format.sh, I got the following output

For run-ci-checks.sh, I got the following output in the terminal

I am attaching the log file for run-ci-checks.sh. I see that the lint script ran without errors. I am not sure what I am doing wrong. Kindly request your assistance.

run-ci-checks.log

https://github.com/zenml-io/zenml/actions/runs/8307099335/job/22735937951?pr=2533#step:5:27 this is the specific thing you need to fix first of all.

[adtygan]

In the commit I had made I do see the import at Line 25 SHA is: 34d179ca47be2927e1e0af77f5dd25d4971e186a

But after this, there was another commit made by you, and in this version I cannot see the import anymore SHA is: 64a1e745e4b38efc5ff4ce9c6738e95199f4dd50

I am not sure why this is happening.

It seems like maybe you're using an old version of the ruff formatter @adtygan? Can you pip install "zenml[server,dev]" again in your environment to make sure you're using the latest version, then rerun the script and push the changes? We def shouldn't be seeing changes to all these files in the PR.

[adtygan]

I figured out that I was working on a fork of the repo so my develop branch was out of date. I pulled the updates from upstream and then pushed my changes. Please review.

[strickvl]

There are quite a few updated files in here that shouldn't need to be updated. Not sure what happened on your side or with the fork, but since the changes are small, it might be worth resetting this branch somehow so that only the changes you made are reflected in the changed files?

[adtygan]

I only made a change to the logging/step_logging.py file. But when I run the format.sh script it modifies a lot of other files. Can I run the script on only the login file and push a commit? I think that should fix the issue.

[strickvl]

You could try that, but the point is that the other previously-modified files will still have been previously committed. have you made sure to installed / upgraded the latest version of the dev tools? Probably if you do pip install -U ruff that would be enough, since that's the package that's modifying / formatting files...

I upgraded zenml but not ruff. I will do this also and then try once more like you mentioned.

[strickvl]

Yeah the updates to the important formatting packages will only come when you update zenml[dev] packages, not just core zenml @adtygan

[adtygan]

I had already run pip install "zenml[server,dev]" the last time. But this was using ruff 0.1.7. I ran pip install -U ruff after this like you suggested and it upgraded to version 0.3.4. When I ran format.sh now, it doesn't raise any errors. So I have now pushed my changes.

[adtygan]

May I please know if there is any action required from my end to solve this issue?

[strickvl]

@bcdurak is looking into it / at it

[adtygan]

Thank you for your review @bcdurak . I agree with the points you have mentioned above. If I am allowed to propose a GCP specific solution, I have 2 approaches in mind.

1. Patch the time limit as well so that my current solution can work.
2. GCP, if I'm not wrong, allows some other way to create mutable files. But as far as I know, it won't be a GCS object. I will look into using these tools to solve the problem.

Which of the 2 routes do you suggest?

Thanks

[strickvl]

[bcdurak]

Hey @adtygan,

I think the second approach would be better here if possible. The first one is still viable but I would only apply it if the active artifact store is a GCS artifact store.

As I mentioned before, logging has been an integral part of ZenML and we will be working on improving the user experience when it comes to handling these log messages. @safoinme is currently taking a look at our implementation. He can also share any insights and recommendations he comes across.

[adtygan]

Thank you for your inputs @bcdurak . I will see how I can implement option 2. @safoinme could you please share your insights?
