What this PR does / why we need it:

The virtctl binary download from the cluster CLI route can fail with SSLEOFError during TLS handshake, causing all tests depending on the virtctl_binary fixture to fail in setup.

Wraps the download in TimeoutSampler to retry on SSLError and ConnectionError for up to 2 minutes (10s between attempts).

Which issue(s) this PR fixes:

Cherry-pick source for https://github.com/RedHatQE/cnv-tests/pull/3497

Special notes for reviewer:

Tested on cluster c01-ahmad422 — both error path and happy path tests passed:

  • TestDisconnectedVirtctlDownload::test_download_virtcli_binary (gating) - PASSED
  • TestDisconnectedVirtctlDownloadAndExecute::test_download_and_execute_virtcli_binary_linux (gating) - PASSED

Review Change Stack

📝 Walkthrough

Walkthrough

utilities/infra.py now downloads the archive through a streamed helper and retries it with TimeoutSampler on SSLError and ConnectionError until it succeeds or times out.

Changes

Retry download with TimeoutSampler

Layer / File(s) Summary
Inner download helper and retry loop
utilities/infra.py
_download_file() streams the GET response into local_file_name, raises on HTTP errors, and returns True. A TimeoutSampler loop calls it until success, retrying only SSLError and ConnectionError.

Inline comments:
In `@utilities/infra.py`:
- Line 695: The requests.get() call in the archive download function disables
TLS certificate verification with verify=False, creating a security
vulnerability where downloads could be intercepted. Enable certificate
verification by changing verify=False to verify=True in the requests.get() call,
or provide the path to a proper CA bundle if the target server uses a custom
certificate authority. Additionally, remove the urllib3.disable_warnings() call
that was suppressing SSL warnings, as proper certificate validation should now
be in place. The retry loop should handle legitimate transient network errors
without compromising security by disabling certificate checks.
- Around line 695-706: The requests.get() call in the _download_file function
lacks a timeout parameter, which allows a stalled socket to block indefinitely
and bypass the TimeoutSampler retry envelope. Additionally, the exceptions_dict
in the TimeoutSampler does not include requests.exceptions.Timeout, so timeout
exceptions won't be caught and retried. Add a timeout parameter (with an
appropriate value) to the requests.get() call, and add
requests.exceptions.Timeout to the exceptions_dict alongside the existing
requests.exceptions.SSLError and requests.exceptions.ConnectionError entries to
ensure transient hangs are properly retried.

**: # AI Review and Development Standards

Assisted-by: Claude noreply@anthropic.com

Coding standards, conventions, and review guidelines for openshift-virtualization-tests.

These rules apply to ALL contributors and review tools — human and AI alike.

Strict Rules (MANDATORY)

Linter Suppressions PROHIBITED

  • NEVER add # noqa, # type: ignore, # pylint: disable
  • NEVER disable linter/mypy rules to work around issues
  • FIX THE CODE - If linter complains, the code is wrong
  • If you think a rule is wrong: ASK the user for explicit approval

Code Reuse (Search-First Development)

Before writing ANY new code:

  1. SEARCH codebase for existing implementations
  2. CHECK utilities/ for shared functions
  3. CHECK libs/ for shared libraries
  4. CHECK tests/ for shared fixtures and helper functions
  5. CHECK pyproject.toml dependencies — project packages (e.g., pyhelper-utils, ocp-resources, openshift-python-wrapper) may already provide the functionality
  6. VERIFY no similar logic exists elsewhere
  7. NEVER duplicate logic - extract to shared module
  8. REUSE existing code and patterns — only write new when nothing exists

External package examples:

  • Shell commands — use pyhelper_utils.shell.run_command, NEVER use subprocess.run directly in test/utility code
  • OpenShift resources — use ocp-resources classes, NEVER construct raw YAML dicts

Python Requirements

  • Type hints MANDATORY - mypy strict mode in libs/, all new public functions under utilities MUST be typed
  • Use TYPE_CHECKING for type-only imports - wrap imports needed solely for type hints in if TYPE_CHECKING: to avoid runtime overhead and circular imports
  • Google-format docstrings REQUIRED - for all public functions with non-obvious return values OR side effects
  • No defensive programming - fail-fast, don't hide bugs with fake defaults (see exceptions below)

Check the PR description for required sections from .github/pull_request_template.md.
Required sections (must be present, even if empty):

  • ##### What this PR does / why we need it: — MUST be present AND have meaningful content.
    Flag as HIGH if the section is missing, empty, whitespace-only, contains only HTML comments,
    or contains only placeholder tokens such as TBD, TBA, N/A, -, , none, or ..
  • ##### Which issue(s) this PR fixes: — must be present (may be empty)

    If any required section is absent, or What this PR does / why we need it: has no content,
    flag it as HIGH severity and ask the author to restore the missing template section(s).

Approval Policy

You may approve the PR when ALL of the following are true:

  • All your review comments have been addressed with either:
    • a code/doc change that fixes the issue, or
    • a substantive author response that justifies no code change.
      Thread "resolved" state alone is not sufficient.
      OR you had no review comments.
  • If you posted a test execution plan comment requesting tests, and the PR author replied
    with a comment explaining why the requested tests are not needed or were already covered,
    treat that as an acceptable response — do not block approval on the test plan alone.
  • The author's explanation must be reasonable and specific (not just "N/A" or "not needed").
    Accept explanations like: "these tests were already run in CI", "this change is docs-only",
    "the affected tests are quarantined", or "verified manually on cluster X".

Learning: In Python tests and utility code across the repository, bitmath.parse_string_unsafe correctly parses Kubernetes quantities (e.g., '4Gi', '512Mi', PVC storage requests) without supplying system=bitmath.NIST. There are 30+ usages indicating this is the standard behavior. Reviewers should verify that code that builds or compares quantity strings does not pass the NIST parameter, and if a new test relies on quantity parsing, assume no NIST parameter is required unless explicitly documented.

Learning: In the openshift-virtualization-tests repository, Python imports should consistently use module-level imports for the logging module (i.e., import logging) rather than from logging import ...

If you use an 'as' binding (e.g., 'except (ValueError, TypeError) as e:'), parentheses are required. Ensure this pattern is version-consistent and not flagged as Python 2 syntax when 'as' is absent.

Learning: In Python code, a function named clearly and self-descriptively can be deemed not to require a docstring. However, treat this as a context-specific guideline and not a universal rule. For public APIs or functions with side effects, prefer concise docstrings explaining behavior, inputs, outputs, and side effects. This guidance is based on the example in utilities/virt.py from RedHatQE/openshift-virtualization-tests where validate_libvirt_persistent_domain(vm, admin_client) was considered self-documenting.

Learning: In Python code reviews, the guideline to always use named arguments for multi-argument calls does not apply to built-ins or methods that have positional-only parameters (those defined with a / in their signature). Do not flag or require named arguments for calls like dict.get(key, default=None, /), list.pop(), str.split(sep, maxsplit) and similar built-ins that cannot accept keyword arguments. Apply the named-argument rule only to functions/methods that explicitly accept keyword arguments.

Learning: When reviewing lint-cleanup or formatting-only pull requests in this repo (e.g., changes like removing/updating `# noqa` comments or UTF-8 headers), do not raise findings for code patterns that already existed before the PR. Specifically, if a problematic construct such as `.is_connective(tcp_timeout=120)` was present in the base branch, suppress that finding and only raise issues when the PR itself introduces or modifies that construct (i.e., the diff adds/changes the call or its arguments). Apply this rule across all Python files (`**/*.py`).

Learning: In this repo’s Python code, it’s acceptable (and preferred by convention) to build `run_command` inputs using `shlex.split(f"<command> {arg}")` rather than converting to direct list literals like `['oc', 'adm', 'uncordon', name]`. During code review, generally don’t flag `shlex.split(...)` usage for `run_command` calls and don’t suggest replacing it with list literals; the string-form pattern is used to keep commands readable and consistent with how they’re typed in a terminal.

Learning: In this repository, Ruff rule UP043 ("unnecessary default type arguments") is enforced. When annotating `collections.abc.Generator` return types, prefer the single-parameter form `Generator[YieldType]` rather than `Generator[YieldType, None, None]`. Explicit `None, None` for the SendType and ReturnType are unnecessary defaults (per PEP 696) and will trigger UP043. Apply this consistently across all Python files.

Learning: During Ruff/lint rule-enablement PRs in this repository (e.g., when introducing a new rule like PLC0415), it’s acceptable to keep CI green by adding per-line, targeted suppressions for pre-existing violations: add only `# noqa: <single-ruff-rule-id>` at the end of the specific violating line. In this PR context, reviewers should NOT flag these targeted `# noqa: PLC0415` comments as policy violations, assuming the suppression is for a pre-existing issue and is documented in the PR description as a candidate for follow-up cleanup. Do not allow blanket `# noqa` (without a specific rule) or `per-file-ignores`; those remain disallowed.

Learning: In RedHatQE/openshift-virtualization-tests, if a PR is a Ruff rule-enforcement PR and its “Special notes for reviewer” documents that pre-existing Ruff violations are being temporarily handled via per-line suppressions (e.g., `# noqa: PLC0415`) to keep CI green, reviewers should treat those specific `# noqa: <rule>` comments as an agreed, temporary mechanism. Do not flag them as code-quality issues and do not recommend removing, consolidating, or refactoring those suppressions within the same PR; cleanup/remediation is expected to happen in dedicated follow-up PRs instead.

Learning: When reviewing Python code in this repository for Ruff/linter rule rollouts, do not treat temporary suppression comments as violations in the specific migration scenario where a PR enables a new Ruff rule (e.g., PLC0415) and the PR description explicitly documents that all *pre-existing* violations are being annotated with `# noqa: <RULE>` as a short-lived measure. In that case, only flag `# noqa: <RULE>` suppressions that are newly introduced on code that did not previously violate the rule—i.e., verify via the PR diff against the prior state (and/or prior Ruff findings) that the suppressed line was already violating before the rule was enabled. Ignore suppressions that are covering violations that existed before the new rule rollout and were intentionally bulk-added for cleanup in follow-up PRs.

Learning: When reviewing Python code in RedHatQE/openshift-virtualization-tests, avoid flagging Ruff `# noqa: <RULE>` suppressions as issues if they were intentionally added as a temporary measure to keep CI green after a PR enables a new Ruff/lint rule (e.g., PLC0415) and the PR description documents this under "Special notes for reviewer". Treat these suppressions as deferred technical debt. Only flag `# noqa: PLC0415` (and similar rule-specific suppressions) when they are newly introduced without an accompanying documented intent in the PR (and thus appear to be masking a new violation rather than a pre-existing one).

Learning: When constructing Kubernetes `NodeSelectorRequirement` (or `LabelSelectorRequirement`) objects in code, do not treat `values` being omitted, `None`, or an empty list as an API-validation problem when the requirement’s operator is `Exists` or `DoesNotExist`. Per the Kubernetes API spec, these operators only require that the `values` array is not non-empty (i.e., it must be empty); they do not require the field to be explicitly present as `[]`. Therefore, reviewers should not flag `values=None`/missing `values` for `Exists`/`DoesNotExist`.

CRITICAL: TLS certificate verification is disabled for archive downloads

Line 695 disables certificate validation (verify=False) when downloading archive files, creating a man-in-the-middle vulnerability. Archives could be intercepted and modified before extraction. The TODO comment on line 691 confirms this was a known issue.

Replace verify=False with proper certificate validation (use the cluster CA bundle or system default). The retry loop should handle transient network errors—it should not suppress certificate validation to work around SSL issues. Also remove the urllib3.disable_warnings() call on line 691 once certificate handling is fixed.

Example fix:

with requests.get(url=url, verify=True, stream=True, timeout=TIMEOUT_30SEC) as response:

If the target server uses a custom CA, pass the CA bundle path: verify="/path/to/ca-bundle.crt".

Add request timeout and handle timeout exceptions in retry loop

The requests.get() call at line 695 lacks a timeout parameter, which means a single stalled socket can block indefinitely and outlive the TimeoutSampler retry envelope. Additionally, timeout exceptions are not included in the exceptions_dict, so even if a timeout occurs, the retry loop won't catch and retry it.

Add a timeout to requests.get() and include requests.exceptions.Timeout in exceptions_dict so transient hangs are properly retried:

The virtctl binary download from the cluster CLI route can fail with
SSLEOFError during TLS handshake, causing all tests depending on the
virtctl_binary fixture to fail in setup. Wrap the download in
TimeoutSampler to retry on SSLError and ConnectionError for up to
2 minutes (10s between attempts).

Moves the full download+write logic into a nested callable so that
streaming errors (e.g. SSLError mid-transfer) are also retried by
TimeoutSampler. Uses `with` on the response to prevent connection leaks.

verification enabled by default, and if a special case is needed, handle it
explicitly and securely rather than turning verification off. Keep the change
localized to the code path that streams the response from requests.get.
- Around line 695-706: The download helper in _download_file currently makes a
requests.get call without a per-request timeout, and the surrounding
TimeoutSampler retry list does not include requests.exceptions.Timeout. Update
_download_file to pass an explicit request timeout, and extend the
exceptions_dict in the TimeoutSampler call so Timeout is retried alongside
SSLError and ConnectionError, keeping the behavior localized to the download
loop.

**: # AI Review and Development Standards

Assisted-by: Claude noreply@anthropic.com

Coding standards, conventions, and review guidelines for openshift-virtualization-tests.

These rules apply to ALL contributors and review tools — human and AI alike.

Strict Rules (MANDATORY)

Linter Suppressions PROHIBITED

  • NEVER add # noqa, # type: ignore, # pylint: disable
  • NEVER disable linter/mypy rules to work around issues
  • FIX THE CODE - If linter complains, the code is wrong
  • If you think a rule is wrong: ASK the user for explicit approval

Code Reuse (Search-First Development)

Before writing ANY new code:

  1. SEARCH codebase for existing implementations
  2. CHECK utilities/ for shared functions
  3. CHECK libs/ for shared libraries
  4. CHECK tests/ for shared fixtures and helper functions
  5. CHECK pyproject.toml dependencies — project packages (e.g., pyhelper-utils, ocp-resources, openshift-python-wrapper) may already provide the functionality
  6. VERIFY no similar logic exists elsewhere
  7. NEVER duplicate logic - extract to shared module
  8. REUSE existing code and patterns — only write new when nothing exists

External package examples:

  • Shell commands — use pyhelper_utils.shell.run_command, NEVER use subprocess.run directly in test/utility code
  • OpenShift resources — use ocp-resources classes, NEVER construct raw YAML dicts

Python Requirements

  • Type hints MANDATORY - mypy strict mode in libs/, all new public functions under utilities MUST be typed
  • Use TYPE_CHECKING for type-only imports - wrap imports needed solely for type hints in if TYPE_CHECKING: to avoid runtime overhead and circular imports
  • Google-format docstrings REQUIRED - for all public functions with non-obvious return values OR side effects
  • No defensive programming - fail-fast, don't hide bugs with fake defaults (see exceptions below)
  • ALWAYS use uv run -...

**: ## PR Template Validation
Check the PR description for required sections from .github/pull_request_template.md.
Required sections (must be present, even if empty):

  • ##### What this PR does / why we need it: — MUST be present AND have meaningful content.
    Flag as HIGH if the section is missing, empty, whitespace-only, contains only HTML comments,
    or contains only placeholder tokens such as TBD, TBA, N/A, -, , none, or ..
  • ##### Which issue(s) this PR fixes: — must be present (may be empty)
  • ##### Special notes for reviewer: — must be present (may be empty)
  • ##### jira-ticket: — must be present (may be empty)
    If any required section is absent, or What this PR does / why we need it: has no content,
    flag it as HIGH severity and ask the author to restore the missing template section(s).

Approval Policy

You may approve the PR when ALL of the following are true:

  • All your review comments have been addressed with either:
    • a code/doc change that fixes the issue, or
    • a substantive author response that justifies no code change.
      Thread "resolved" state alone is not sufficient.
      OR you had no review comments.
  • If you posted a test execution plan comment requesting tests, and the PR author replied
    with a comment explaining why the requested tests are not needed or were already covered,
    treat that as an acceptable response — do not block approval on the test plan alone.
  • The author's explanation must be reasonable and specific (not just "N/A" or "not needed").
    Accept explanations like: "these tests were already run in CI", "this change is docs-only",
    "the affected tests are quarantined", or "verified manually on cluster X".

Learning: In Python tests and utility code across the repository, bitmath.parse_string_unsafe correctly parses Kubernetes quantities (e.g., '4Gi', '512Mi', PVC storage requests) without supplying system=bitmath.NIST. There are 30+ usages indicating this is the standard behavior. Reviewers should verify that code that builds or compares quantity strings does not pass the NIST parameter, and if a new test relies on quantity parsing, assume no NIST parameter is required unless explicitly documented.

Learning: In Python code, a function named clearly and self-descriptively can be deemed not to require a docstring. However, treat this as a context-specific guideline and not a universal rule. For public APIs or functions with side effects, prefer concise docstrings explaining behavior, inputs, outputs, and side effects. This guidance is based on the example in utilities/virt.py from RedHatQE/openshift-virtualization-tests where validate_libvirt_persistent_domain(vm, admin_client) was considered self-documenting.

Learning: In Python code reviews, the guideline to always use named arguments for multi-argument calls does not apply to built-ins or methods that have positional-only parameters (those defined with a / in their signature). Do not flag or require named arguments for calls like dict.get(key, default=None, /), list.pop(), str.split(sep, maxsplit) and similar built-ins that cannot accept keyword arguments. Apply the named-argument rule only to functions/methods that explicitly accept keyword arguments.

Learning: When reviewing lint-cleanup or formatting-only pull requests in this repo (e.g., changes like removing/updating `# noqa` comments or UTF-8 headers), do not raise findings for code patterns that already existed before the PR. Specifically, if a problematic construct such as `.is_connective(tcp_timeout=120)` was present in the base branch, suppress that finding and only raise issues when the PR itself introduces or modifies that construct (i.e., the diff adds/changes the call or its arguments). Apply this rule across all Python files (`**/*.py`).

Learning: In this repo’s Python code, it’s acceptable (and preferred by convention) to build `run_command` inputs using `shlex.split(f"<command> {arg}")` rather than converting to direct list literals like `['oc', 'adm', 'uncordon', name]`. During code review, generally don’t flag `shlex.split(...)` usage for `run_command` calls and don’t suggest replacing it with list literals; the string-form pattern is used to keep commands readable and consistent with how they’re typed in a terminal.

If Ruff configuration changes and starts selecting FBT rules, this exception should be reconsidered.

Learning: In this repository, Ruff rule UP043 ("unnecessary default type arguments") is enforced. When annotating `collections.abc.Generator` return types, prefer the single-parameter form `Generator[YieldType]` rather than `Generator[YieldType, None, None]`. Explicit `None, None` for the SendType and ReturnType are unnecessary defaults (per PEP 696) and will trigger UP043. Apply this consistently across all Python files.

Learning: During Ruff/lint rule-enablement PRs in this repository (e.g., when introducing a new rule like PLC0415), it’s acceptable to keep CI green by adding per-line, targeted suppressions for pre-existing violations: add only `# noqa: <single-ruff-rule-id>` at the end of the specific violating line. In this PR context, reviewers should NOT flag these targeted `# noqa: PLC0415` comments as policy violations, assuming the suppression is for a pre-existing issue and is documented in the PR description as a candidate for follow-up cleanup. Do not allow blanket `# noqa` (without a specific rule) or `per-file-ignores`; those remain disallowed.

Learning: In RedHatQE/openshift-virtualization-tests, if a PR is a Ruff rule-enforcement PR and its “Special notes for reviewer” documents that pre-existing Ruff violations are being temporarily handled via per-line suppressions (e.g., `# noqa: PLC0415`) to keep CI green, reviewers should treat those specific `# noqa: <rule>` comments as an agreed, temporary mechanism. Do not flag them as code-quality issues and do not recommend removing, consolidating, or refactoring those suppressions within the same PR; cleanup/remediation is expected to happen in dedicated follow-up PRs instead.

Learning: When reviewing Python code in this repository for Ruff/linter rule rollouts, do not treat temporary suppression comments as violations in the specific migration scenario where a PR enables a new Ruff rule (e.g., PLC0415) and the PR description explicitly documents that all *pre-existing* violations are being annotated with `# noqa: <RULE>` as a short-lived measure. In that case, only flag `# noqa: <RULE>` suppressions that are newly introduced on code that did not previously violate the rule—i.e., verify via the PR diff against the prior state (and/or prior Ruff findings) that the suppressed line was already violating before the rule was enabled. Ignore suppressions that are covering violations that existed before the new rule rollout and were intentionally bulk-added for cleanup in follow-up PRs.

Treat these suppressions as deferred technical debt. Only flag `# noqa: PLC0415` (and similar rule-specific suppressions) when they are newly introduced without an accompanying documented intent in the PR (and thus appear to be masking a new violation rather than a pre-existing one).

Learning: When using Kubernetes API models like `NodeSelectorRequirement` or `LabelSelectorRequirement` with operators `Exists` or `DoesNotExist`, the `values` field must not be non-empty. It is valid for `values` to be omitted / left as `None` (Python) / passed as `null`—Kubernetes rejects non-empty `values` for these operators, but does not require the field to be present or explicitly set to an empty list. In code reviews, do not treat missing `values=[]` for `Exists`/`DoesNotExist` as a validation issue; only flag cases where `values` is provided with actual elements.

Learning: When constructing Kubernetes `NodeSelectorRequirement` (or `LabelSelectorRequirement`) objects in code, do not treat `values` being omitted, `None`, or an empty list as an API-validation problem when the requirement’s operator is `Exists` or `DoesNotExist`. Per the Kubernetes API spec, these operators only require that the `values` array is not non-empty (i.e., it must be empty); they do not require the field to be explicitly present as `[]`. Therefore, reviewers should not flag `values=None`/missing `values` for `Exists`/`DoesNotExist`.

Learning: In this repository, under the Python `utilities/` directory (utility/helper modules, not tests), do not flag bare `assert` statements as correctness or style issues. The codebase conventionally uses `assert` in these utilities (e.g., `utilities/virt.py`, `utilities/infra.py`, etc.) and does not enforce running Python with `-O`/`PYTHONOPTIMIZE`, so the usual “asserts may be stripped” concern should not be treated as a review blocker here.

Learning: In this repository, do not require or flag missing `-> None` return type annotations on pytest test functions/methods (i.e., functions named `test_*`) located under `tests/**`. Return type annotations for `-> None` on these test functions are optional and should not be treated as inconsistent. Separately, in `utilities/**` and `libs/**`, enforce return type annotations for non-test public functions (e.g., functions that are not internal/private such as those not starting with `_`).
