From 75ede791588cc9f8d9a7890114071ee15ece624d Mon Sep 17 00:00:00 2001 From: Adam Ling Date: Tue, 30 Jun 2026 20:59:38 +0000 Subject: [PATCH 1/4] SNOW-3718333: Escape backslashes and single quotes in stage/file path SQL generation Stage and file paths passed to COPY INTO / PUT / GET were escaped for single quotes but not backslashes, so a path containing a backslash followed by a single quote produced invalid SQL. normalize_path now escapes backslashes before single quotes so the path stays a single string literal. Adds unit tests and integ tests covering Snowpark write.csv and Snowpark-pandas to_csv with quote/backslash paths. --- CHANGELOG.md | 1 + src/snowflake/snowpark/_internal/utils.py | 8 ++- tests/integ/modin/io/test_to_csv.py | 58 +++++++++++++++- .../scala/test_dataframe_writer_suite.py | 49 ++++++++++++++ tests/unit/scala/test_utils_suite.py | 4 +- tests/unit/test_internal_utils.py | 66 +++++++++++++++++++ 6 files changed, 183 insertions(+), 3 deletions(-) diff --git a/CHANGELOG.md b/CHANGELOG.md index 7b00d66cbb..8a84e18694 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -7,6 +7,7 @@ #### Bug Fixes - Fixed a bug where stage paths and file format names that contain single quotes were not consistently escaped when generating SQL, which could produce malformed statements. This affects `INFER_SCHEMA` (used by `DataFrameReader.csv`/`json`/`parquet`/`orc`/`avro`) and `COPY FILES` (used by `FileOperation.copy_files`). +- Fixed a bug where single quotes and backslashes in stage/file paths were not correctly escaped when generating `COPY INTO` / `PUT` / `GET` SQL, which could produce malformed statements. This affects `DataFrame.write.csv`/`copy_into_location` and the Snowpark-pandas `DataFrame.to_csv` stage path. - Fixed a bug where UDF default argument values reconstructed from a source file in `register_from_file` were evaluated with `eval()`; they are now evaluated only against the documented set of supported default-value types, and unsupported expressions are ignored. - Fixed a bug where `object_name`, `object_domain`, or `object_version` values containing single quotes or backslashes in `session.lineage.trace()` caused incorrect SQL generation. These values are now properly escaped before being embedded in the `SYSTEM$DGQL` call. diff --git a/src/snowflake/snowpark/_internal/utils.py b/src/snowflake/snowpark/_internal/utils.py index 7927f5d37f..d2d258d759 100644 --- a/src/snowflake/snowpark/_internal/utils.py +++ b/src/snowflake/snowpark/_internal/utils.py @@ -429,7 +429,13 @@ def normalize_path(path: str, is_local: bool) -> str: return path if is_local and OPERATING_SYSTEM == "Windows": path = path.replace("\\", "/") - path = path.strip().replace("'", "\\'") + # Escape characters that are special inside a Snowflake single-quoted string + # literal.
