Add version.go with semantic version constants (v0.1.0) - Defines Major, Minor, Patch version numbers - Includes PreRelease and BuildMetadata support - Provides FullVersion() and VersionInfo() functions - Add version_test.go with complete test suite - Tests version constants and format validation - Validates semantic versioning compliance - Tests FullVersion() and VersionInfo() functions - Includes benchmark tests - All tests passing - Add VERSIONING.md documentation (7.3 KB) - Explains semantic versioning strategy - Documents automated and manual release processes - Covers patch, minor, and major release examples - Includes pre-release version guidelines - Provides troubleshooting and usage instructions - Add PUBLISHING.md guide (12 KB) - Step-by-step release process with commands - Pre-publishing checklist for quality assurance - Version-specific guidelines - Post-publishing tasks and announcements - Emergency rollback procedures - Troubleshooting common release issues - Update Makefile with version management targets - make version: Display current version - make version-info: Show detailed version information - make check-version: Verify version consistency - make release-prep: Run all pre-release checks - make tag VERSION=vX.Y.Z: Create release tag The versioning system enables programmatic access to version info and provides a complete workflow for managing releases. --- Makefile | 73 +++++++ PUBLISHING.md | 539 ++++++++++++++++++++++++++++++++++++++++++++++++ VERSIONING.md | 330 +++++++++++++++++++++++++++++ version.go | 49 +++++ version_test.go | 182 ++++++++++++++++ 5 files changed, 1173 insertions(+) create mode 100644 PUBLISHING.md create mode 100644 VERSIONING.md create mode 100644 version.go create mode 100644 version_test.go diff --git a/Makefile b/Makefile index 93dfdd9..ec95b03 100644 --- a/Makefile +++ b/Makefile @@ -7,6 +7,7 @@ .PHONY: coverage coverage-html .PHONY: vet fmt check-fmt lint .PHONY: clean clean-all ci pre-commit +.PHONY: version version-info check-version tag release-prep # Default target -

(v0.1.1 → v0.2.0) + +**When**: New features, backward-compatible API additions + +```go +const ( + Major = 0 + Minor = 2 + Patch = 0 + Version = "v0.2.0" +) +``` + +**Example changes**: +- Added support for custom hash functions +- New `BatchContains()` method +- Additional configuration options + +### Major Release (v0.2.0 → v1.0.0) + +**When**: Breaking API changes, architectural changes + +```go +const ( + Major = 1 + Minor = 0 + Patch = 0 + Version = "v1.0.0" +) +``` + +**Example changes**: +- Changed function signatures +- Removed deprecated APIs +- Restructured package layout + +## Best Practices + +1. **Always run tests**: Never tag a release with failing tests +2. **Update CHANGELOG**: Keep a detailed changelog for users +3. **Use annotated tags**: Include meaningful commit messages in tags +4. **Document breaking changes**: Clearly explain what changed and why +5. **Provide migration guides**: Help users upgrade smoothly +6. **Follow semantic versioning**: Be consistent and predictable +7. **Test pre-releases**: Use alpha/beta versions for major changes + +## Troubleshooting + +### Wrong Tag Version + +If you created a tag with the wrong version: + +```bash +# Delete local tag +git tag -d vX.Y.Z + +# Delete remote tag +git push origin :refs/tags/vX.Y.Z + +# Create correct tag +git tag -a vX.Y.Z -m "Release vX.Y.Z" +git push origin vX.Y.Z +``` + +### Update Existing Tag + +**WARNING**: Only do this for unpublished releases! + +```bash +# Delete and recreate tag +git tag -d vX.Y.Z +git push origin :refs/tags/vX.Y.Z +git tag -a vX.Y.Z -m "Release vX.Y.Z" +git push origin vX.Y.Z +``` + +### Go Module Not Updated + +If the Go module proxy doesn't show your new version: + +```bash +# Request explicit update +curl "https://proxy.golang.org/github.com/shaia/simdcuckoofilter/@v/vX.Y.Z.info" + +# Check available versions +go list -m -versions github.com/shaia/simdcuckoofilter + +# Clear local cache and refetch +go clean -modcache +go get github.com/shaia/simdcuckoofilter@vX.Y.Z +``` + +## For Users + +### Installing a Specific Version + +```bash +# Install latest version +go get github.com/shaia/simdcuckoofilter@latest + +# Install specific version +go get github.com/shaia/simdcuckoofilter@v0.1.0 + +# Install from main branch +go get github.com/shaia/simdcuckoofilter@main +``` + +### Checking Version in Your Code + +```go +import ( + "fmt" + "github.com/shaia/simdcuckoofilter" +) + +func main() { + fmt.Println("Using SIMDCuckooFilter version:", simdcuckoofilter.Version) + + // Get full version info + info := simdcuckoofilter.VersionInfo() + fmt.Printf("Version details: %+v\n", info) +} +``` + +## Version History + +See
