From 6c387abfbb0a42fbd5a26b4f8069b667b35a990d Mon Sep 17 00:00:00 2001 From: Ole-Morten Duesund Date: Tue, 5 Aug 2025 19:20:22 +0200 Subject: [PATCH] feat: complete code formatting and linting compliance MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Fix all Rust clippy warnings with targeted #[allow] attributes for justified cases - Implement server-side IMAP SEARCH keyword filtering in Go implementation - Add graceful fallback from server-side to client-side filtering when IMAP server lacks SEARCH support - Ensure both implementations use identical filtering logic for consistent results - Complete comprehensive testing of filtering and attachment handling functionality - Verify production readiness with proper linting standards for both Go and Rust 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- go/config/config.go | 6 + go/mail/imap.go | 258 +++++++++++++++++++++++---- go/main.go | 4 +- rust/src/cli.rs | 32 ++-- rust/src/config.rs | 35 ++-- rust/src/couch.rs | 177 +++++++++++------- rust/src/filters.rs | 79 ++++---- rust/src/imap.rs | 337 ++++++++++++++++++++++------------- rust/src/lib.rs | 12 +- rust/src/main.rs | 23 +-- rust/src/schemas.rs | 40 +++-- rust/src/sync.rs | 270 ++++++++++++++++------------ test-both-implementations.sh | 10 +- 13 files changed, 851 insertions(+), 432 deletions(-) diff --git a/go/config/config.go b/go/config/config.go index 713e73d..b7bf6ca 100644 --- a/go/config/config.go +++ b/go/config/config.go @@ -45,6 +45,12 @@ type MessageFilter struct { RecipientKeywords []string `json:"recipientKeywords,omitempty"` // Filter by keywords in recipient addresses } +// HasKeywordFilters checks if this filter has any keyword-based filters that can use IMAP SEARCH +func (mf *MessageFilter) HasKeywordFilters() bool { + return len(mf.SubjectKeywords) > 0 || len(mf.SenderKeywords) > 0 + // Note: RecipientKeywords not included as IMAP SEARCH doesn't have a reliable TO field search +} + func LoadConfig(path string) (*Config, error) { configFile, err := os.Open(path) if err != nil { diff --git a/go/mail/imap.go b/go/mail/imap.go index 712a0eb..5894a12 100644 --- a/go/mail/imap.go +++ b/go/mail/imap.go @@ -85,12 +85,12 @@ func (c *ImapClient) ListMailboxes() ([]string, error) { // ListFilteredMailboxes lists mailboxes matching the given folder filters using IMAP LIST func (c *ImapClient) ListFilteredMailboxes(filter *config.FolderFilter) ([]string, error) { var allMailboxes []string -
