Add python script to view archived pipelinerun logs - #3528
Conversation
In theory you can view them in the UI, but lately I've been seeing gateway timeout errors and a endless spinner in the UI. Note that I think the UI uses Tekton Results instead of Kubearchive, but I'm not sure. Created this to save some pain while working on https://redhat.atlassian.net/browse/EC-2011 Co-authored-by: Simon Baird <sbaird@redhat.com>

1. Bearer token sent insecurely 🐞 Bug ⛨ Security
Client disables certificate and hostname verification before sending the user's bearer token, allowing an intercepted or impersonated route to capture that credential and alter returned logs. The risk also applies to arbitrary hosts supplied through KUBEARCHIVE_HOST.
Agent Prompt
## Issue description
The client disables TLS certificate and hostname verification while transmitting a bearer token, exposing credentials and log responses to interception.
## Issue Context
Use normal certificate validation by default. If clusters require a custom CA, support an explicit CA bundle; any insecure mode should require an explicit user option and a warning.

2. Archive requests can hang 🐞 Bug ☼ Reliability
Every archive request calls urlopen without a timeout, so an unresponsive route can block the script indefinitely. Because requests are performed sequentially for every TaskRun and step, any single stalled request prevents the remaining logs from being fetched.
Agent Prompt
## Issue description
Archive HTTP requests have no deadline and can leave the utility blocked indefinitely when the route stalls.
## Issue Context
Apply a finite, configurable timeout to every request and convert timeout/network failures into concise CLI errors.

3. Raw mode still rewrites logs 🐞 Bug ≡ Correctness
--no-headers is advertised as raw output, but successful log lines are always prefixed with the task and step names and their original line endings are reconstructed. This breaks consumers expecting the archived log body unchanged.
Agent Prompt
## Issue description
The `--no-headers` option still adds task/step prefixes and rewrites the returned log body instead of producing raw logs.
## Issue Context
When raw mode is selected, write `body` directly; retain prefixes and separators only in normal display mode.

4. Examples invoke nonexistent script 🐞 Bug ≡ Correctness
All usage examples tell users to run hack/ka-logs.py, but the added file is hack/find-pr-logs.py. Copying the documented commands therefore fails before the utility starts.
Agent Prompt
## Issue description
The built-in examples reference a script path that does not exist in the repository.
## Issue Context
Update every example to use the actual `hack/find-pr-logs.py` filename.

Python urllib.request.urlopen timeout default documentation socket timeout
💡 Result:
In Python's urllib.request.urlopen, the default timeout behavior is determined by the global default timeout setting [1][2]. Specifically, if the optional timeout parameter is not provided, the function uses socket._GLOBAL_DEFAULT_TIMEOUT [3]. Key points regarding this timeout mechanism include: 1. Global Default: When no timeout is explicitly passed to urlopen, it relies on the global timeout set for sockets, which can be configured application-wide using socket.setdefaulttimeout(timeout) [1][3]. 2. Scope: The timeout applies to blocking operations, such as the connection attempt [1][2]. It is important to note that this is a timeout for specific socket-level operations, not a total deadline for the entire request [4]. 3. Applicability: This timeout feature is effective only for HTTP, HTTPS, and FTP connections [1][2]. 4. Exception Handling: While urllib.request.urlopen is designed to wrap socket errors into a urllib.error.URLError, in some scenarios, internal timeouts may bubble up directly as a socket.timeout or TimeoutError [5][4]. Consequently, robust code should be prepared to catch both urllib.error.URLError and relevant socket/TimeoutError exceptions [4].

Set a finite request timeout.
Client._get calls urllib.request.urlopen without a finite timeout. A stalled KubeArchive connection can block the CLI indefinitely. Pass a finite timeout and handle timeout exceptions as command errors.

[high] license-header
Every script in hack/ begins with the Apache 2.0 license header block (Copyright The Conforma Contributors + SPDX-License-Identifier: Apache-2.0) immediately after the shebang. This new file omits it entirely, breaking the universal convention in this directory.
Suggested fix: Add the standard license header as a Python comment block (lines prefixed with #) between the shebang line and the module docstring, matching the format used in all other hack/ scripts.

[medium] TLS verification disabled
SSL certificate verification is unconditionally disabled (check_hostname=False, verify_mode=CERT_NONE). This exposes the Bearer authentication token (sent on line 86) to interception via man-in-the-middle attacks. Unlike oc -k, which requires explicit user opt-in per invocation, this script always disables verification with no way to enable it.
Suggested fix: Default to verifying certificates. If the KubeArchive route uses a custom CA, allow the user to supply a CA bundle via an env var (e.g. KUBEARCHIVE_CA_BUNDLE) or add an explicit --insecure / -k CLI flag.

[low] URL path injection
User-controlled values (args.namespace, args.pipelinerun, and child-derived tr_name/container) are interpolated directly into URL paths without encoding or validation. Impact is limited because this is a local developer CLI tool.
Suggested fix: Use urllib.parse.quote() on path segments before interpolation.

[low] edge-case
get_json calls json.loads(body) on the response body without handling json.JSONDecodeError. If the server returns a 200 status with non-JSON content, the script will crash with an unhelpful traceback.
Suggested fix: Wrap json.loads(body) in a try/except for json.JSONDecodeError and raise a RuntimeError with a snippet of the body.

[low] error-handling
child["name"] uses direct dict indexing while all other API response fields are accessed via .get() with defaults. A missing name field would produce an unhelpful KeyError.

In theory you can view them in the UI, but lately I've been seeing gateway timeout errors and a endless spinner in the UI.
Note that I think the UI uses Tekton Results instead of Kubearchive.
