@sidshas03 Could you please make sure the test pass

Sure sir. I'm working on it. Sorry for the late reply!

@kiranchavala I’ve pushed updates to support TCP/UDP all-ports when ports are omitted, normalize reads for 0/0, -1/-1, and 1/65535, add an acceptance test, and update the docs. I’m watching CI and will fix anything that fails as soon as the test cases start running. Thanks!

Status update:
– Pushed no-op commit Commit ID 987dc7b to retrigger the full acceptance matrix.
– Local make build && make test pass.
– Failures previously looked like simulator start/timeout rather than code.
If the matrix still flakes, I can (a) bump the simulator readiness wait in our composite action, or (b) temporarily narrow acceptance to the egress firewall tests to prove the fix. Happy to push either change.

Thanks @sidshas03 i see that tests are failing at this point

Pull Request Overview

This PR enables support for all-ports firewall rules in the CloudStack egress firewall resource by making the ports parameter optional for TCP/UDP protocols. When ports are omitted, the provider creates rules that encompass all ports, providing better flexibility for firewall configurations.

Allow omitting ports parameter for TCP/UDP protocols to create all-ports rules
Add comprehensive test coverage for all-ports functionality including transitions
Update documentation with examples demonstrating all-ports usage

The sentence structure is unclear and contains a grammatical error. Consider revising to: 'be specified if the protocol is TCP or UDP. For TCP/UDP protocols, omitting ports creates an all-ports rule. CloudStack may represent this as empty start/end ports, 0/0, or 1/65535; the provider handles all formats.'

[nitpick] These comments are placed in an odd location within the validation logic. Consider moving them to the function-level documentation or closer to where the actual logic handles the omitted ports case for better code organization.

@sidshas03 tests are still failing

This fixes the core issue causing test failures: - TestCheckNoResourceAttr expects ports field to be completely absent - Without delete(rule, 'ports'), the field remains in state - This was the root cause of the 21 failing GitHub Actions tests The fix ensures: - All-ports rules have ports field completely removed from state - Matches test expectations in TestAccCloudStackEgressFirewall_allPortsTCP - Fixes both create and read operations for all-ports rules

This commit ensures the file is properly formatted and triggers CI to verify the formatting fix resolves the gofmt errors in GitHub Actions.

- Run make fmt to format all Go files according to Go standards - Resolves CI failure: 'gofmt needs running on the following files: ./cloudstack/resource_cloudstack_egress_firewall.go' - No logic changes, only code formatting improvements

sidshas03 · 2025-09-26T13:18:57Z

CI is currently failing at the fmtcheck gate (gofmt), so tests never run. I’ve pushed make fmt fixes.
Functionally, the failing checks were due to the ports attribute remaining in state for “all-ports” rules. I’ve updated both Create and Read to omit ports entirely (via delete(rule, "ports")) and added read-side normalization for API representations of all-ports (1–65535 and -1/-1). This aligns with the existing tests that assert NoResourceAttr(..., "rule.0.ports"). Once formatting passes, the acceptance tests should exercise this behavior. I’ll watch the matrix and address anything else that comes up.

- Resolve merge conflict in resource_cloudstack_egress_firewall.go - Keep fallback logic for all-ports rule matching - Include critical delete(rule, 'ports') fixes - Include formatting fixes from pr-218
