From a78b47ef9d6850188dbea82b489de1d0abc32e6c Mon Sep 17 00:00:00 2001 From: Wes McKinney Date: Tue, 18 Feb 2020 02:45:14 -0600 Subject: [PATCH 01/26] Refactoring to simplify internal IPC read path for reuse add empty reader_internal.h Some more temporary cutting away / simplification Ongoing refactoring More refactoring and cleaning of Feather V1 More cleaning, simplification Cleaning fixes Get feather.cc compiling again Slightly more working Feather tests passing again Some code reorganization, simply IPC writing a bit Start writer_internal.h Start writer_internal.h Incomplete refactoring Externalize enough of IPC writer machinery to be able to customize for Feather Remove overly elaborate externalization of IPC writer internals, implement compression as part of IpcOptions Work on serializing custom_metadata in Message Fix compilation Test empty metadata case also iwyu Some more work on compression complete more of decompression Decompression draft Implement various deprecations, and get compression tests passing Revert Feather changes --- cpp/src/arrow/CMakeLists.txt | 3 +- cpp/src/arrow/flight/client.cc | 3 - cpp/src/arrow/ipc/dictionary.cc | 8 +- cpp/src/arrow/ipc/dictionary.h | 2 +- cpp/src/arrow/ipc/json_internal.cc | 2 +- cpp/src/arrow/ipc/message.cc | 17 + cpp/src/arrow/ipc/message.h | 4 + cpp/src/arrow/ipc/metadata_internal.cc | 125 +++-- cpp/src/arrow/ipc/metadata_internal.h | 26 +- cpp/src/arrow/ipc/options.h | 19 + cpp/src/arrow/ipc/read_write_test.cc | 110 +++-- cpp/src/arrow/ipc/reader.cc | 616 +++++++++++++------------ cpp/src/arrow/ipc/reader.h | 33 +- cpp/src/arrow/ipc/writer.cc | 462 +++++++++---------- cpp/src/arrow/ipc/writer.h | 89 ++-- cpp/src/arrow/util/compression.cc | 23 + cpp/src/arrow/util/compression.h | 7 +- cpp/src/arrow/util/compression_test.cc | 16 + 18 files changed, 849 insertions(+), 716 deletions(-) diff --git a/cpp/src/arrow/CMakeLists.txt b/cpp/src/arrow/CMakeLists.txt index 3454cd0c87d..66d505913b9 100644 --- a/cpp/src/arrow/CMakeLists.txt +++ b/cpp/src/arrow/CMakeLists.txt @@ -377,7 +377,8 @@ endif() if(ARROW_IPC) list(APPEND ARROW_SRCS ipc/dictionary.cc - ipc/feather.cc + ipc/feather_v1.cc + ipc/feather_v2.cc ipc/message.cc ipc/metadata_internal.cc ipc/options.cc diff --git a/cpp/src/arrow/flight/client.cc b/cpp/src/arrow/flight/client.cc index eae31a52553..02335e4f52b 100644 --- a/cpp/src/arrow/flight/client.cc +++ b/cpp/src/arrow/flight/client.cc @@ -385,9 +385,6 @@ class GrpcStreamWriter : public FlightStreamWriter { } return Status::OK();
