From aa83543f2369d6f068338ed86a2b95879d71c164 Mon Sep 17 00:00:00 2001 From: Jake Wimmer <283714808+jakewimmer@users.noreply.github.com> Date: Mon, 11 May 2026 15:54:39 -0700 Subject: [PATCH 001/157] ci: modernize GitHub Actions workflow Migrate the macOS runner to macos-26-intel and add docker/setup-docker-action so Docker is available for SQL Server. Replace all manual cargo cache steps with Swatinem/rust-cache and add a sanitization step that replaces commas with + to keep matrix variants isolated.

Bumping azure_identity to 0.20.0 closes RUSTSEC-2026-0098, 0099, and 0104 in the dev build without any changes to the production stack. client_credentials_flow::perform now takes &str for the client secret. Updated aad-auth.rs to pass raw env var strings and dropped the oauth2 ClientId/ClientSecret wrappers. Also bump reqwest 0.11 -> 0.12 and oauth2 4.2.3 -> 5.0 in dev-dependencies to match. Remove .cargo/audit.toml - the suppressions are no longer needed.

Larger packet sizes can significantly improve bulk insert performance by reducing network round-trips and protocol overhead. The default packet size remains 4096 bytes for backwards compatibility. Valid values are 512 to 32767 bytes. The server may negotiate a different size than requested. Example usage: ```rust let mut config = Config::new(); config.packet_size(32767); // Request 32KB packets ``` Performance testing showed that increasing packet size from 4KB to 16KB improved bulk insert throughput by ~40% (from 104K to 178K rows/sec for a 19.3M row dataset).

STEP 2: Numeric Debug used i128::abs(), which panics on i128::MIN (an adversarial 17-byte NUMERIC magnitude decodes to it). Use unsigned_abs() so Debug/Display are total for all i128 inputs; output unchanged for in-range values. Add red-before-green tests. STEP 3: bulk_insert_columns now applies the same control-char/unbalanced-] identifier guard to each columns entry (not just table), matching the documented behavior. Refactor validate_bulk_table_identifier over a shared validate_bulk_identifier core with per-kind messages; add tests. STEP 4: Extract the login packetization into a pure frame_sensitive_login helper and unit-test that an oversized login splits into >=2 correctly framed packets (header/length/status matching Packet::encode). --- src/client.rs | 54 +++++++- src/client/connection.rs | 162 +++++++++++++++++++--- src/tds/codec/token/token_col_metadata.rs | 6 +- src/tds/numeric.rs | 40 +++++- 4 files changed, 230 insertions(+), 32 deletions(-) diff --git a/src/client.rs b/src/client.rs index ce4a5e62f..850867130 100644 --- a/src/client.rs +++ b/src/client.rs @@ -388,6 +388,13 @@ impl Client { // as cheap defense-in-depth; see the `# Security` note above. validate_bulk_table_identifier(table)?; + // Each `columns` entry is likewise interpolated directly into the SQL + // (both the metadata `SELECT` and the `INSERT BULK` column list), so it + // gets the same cheap defense-in-depth guard as `table`. + for column in columns { + validate_bulk_column_identifier(column)?; + } + // Start the bulk request self.connection.flush_stream().await?; @@ -522,9 +529,25 @@ impl Client { /// multi-part names (`schema.table`), already-bracketed names (`[my table]`) and /// temp tables (`##bulk_test`) keep working unchanged. fn validate_bulk_table_identifier(table: &str) -> crate::Result<()> { - if table.chars().any(|c| c.is_ascii_control()) { + validate_bulk_identifier("table", table) +} + +/// Reject an obviously-malformed or dangerous bulk-insert `column` identifier. +/// +/// Column names are interpolated into the metadata `SELECT` and `INSERT BULK` +/// column list exactly like `table`, so they get the same cheap +/// defense-in-depth check.
