From c3427e4146418962ad231df01b5a60ab78922d94 Mon Sep 17 00:00:00 2001 From: Eugene Date: Sat, 12 Jul 2025 23:30:53 +0300 Subject: [PATCH 1/2] feat: implement session management system for improved workflow tracking MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add comprehensive session management to resolve workflow ambiguity: - New session metadata storage with query parameters and timestamps - Session status tracking (active, modified) for workflow state - Automatic session creation on query operations - Session validation and cleanup functionality - Collision detection and user warnings for concurrent edits Additional improvements: - Resolve 75% of linting warnings (76→19) for better code quality - Fix exhaustive switch statements and naming conventions - Improve test isolation with _test package naming - Replace os.Chdir with t.Chdir in test functions - Add proper file permissions and error handling --- .golangci-lint.yml => .golangci.yml | 0 Makefile | 11 +- cmd/pho/main.go | 115 ++++++++-- internal/diff/action_test.go | 168 +++++++------- internal/diff/change.go | 18 +- internal/diff/change_test.go | 103 ++++----- internal/hashing/hasher.go | 27 ++- internal/hashing/hasher_test.go | 22 +- internal/hashing/helpers.go | 2 +- internal/hashing/helpers_test.go | 24 +- internal/hashing/identifier.go | 9 +- internal/hashing/identifier_test.go | 20 +- internal/logging/logger.go | 40 ++-- internal/logging/logger_test.go | 60 ++--- internal/pho/app.go | 63 ++--- internal/pho/app_test.go | 71 ++---- internal/pho/helpers.go | 10 +- internal/pho/helpers_test.go | 4 +- internal/pho/model.go | 8 +- internal/pho/model_test.go | 4 +- internal/pho/options_test.go | 7 +- internal/pho/session.go | 196 ++++++++++++++++ internal/pho/session_test.go | 216 ++++++++++++++++++ internal/render/renderer_test.go | 16 +- internal/restore/helpers.go | 2 +- internal/restore/helpers_test.go | 15 +- internal/restore/model.go | 4 +- internal/restore/model_test.go | 18 +- internal/restore/mongo_client_restorer.go | 21 +- .../restore/mongo_client_restorer_test.go | 4 +- internal/restore/mongo_shell_restorer.go | 19 +- internal/restore/mongo_shell_restorer_test.go | 5 +- pkg/extjson/extjson.go | 27 +-- pkg/extjson/extjson_test.go | 2 +- pkg/jsonl/json_comments_cleaner.go | 3 +- pkg/jsonl/jsonl.go | 2 +- pkg/jsonl/jsonl_test.go | 9 +- 37 files changed, 913 insertions(+), 432 deletions(-) rename .golangci-lint.yml => .golangci.yml (100%) create mode 100644 internal/pho/session.go create mode 100644 internal/pho/session_test.go diff --git a/.golangci-lint.yml b/.golangci.yml similarity index 100% rename from .golangci-lint.yml rename to .golangci.yml diff --git a/Makefile b/Makefile index 6adf734..949ca4d 100644 --- a/Makefile +++ b/Makefile @@ -23,7 +23,7 @@ run: build # Run tests .PHONY: test test: - @go test -v ./... + @go test ./... # Tidy: format and vet the code .PHONY: tidy @@ -32,17 +32,10 @@ tidy: @go vet $(PKGS) @go mod tidy -# Install golangci-lint only if it's not already installed -.PHONY: lint-install -lint-install: - @if !
