ARROW-75: Fix handling of empty strings by danrobinson · Pull Request #32 · apache/arrow

danrobinson · 2016-03-22T15:16:36Z

Fixes ARROW-75 (and changes Python tests to verify that behavior).

 RETURN_NOT_OK(Resize(new_capacity));
 }
- memcpy(raw_buffer() + length_, values, length * elsize_);
+if (length > 0) memcpy(raw_buffer() + length_, values, length * elsize_);


Put braces around this (with the memcpy on its own line)?

wesm · 2016-03-22T15:47:19Z

Could you also add a small unit test to types/string-test.cc (appending one or two empty strings and checking the resulting StringArray will suffice)?

danrobinson · 2016-03-22T16:45:12Z

It turns out the empty strings only cause a segfault when they are the first item in the array. Both the Python and C++ tests now test for this behavior.

wesm · 2016-03-22T17:00:34Z

You can add a pre-commit hook to run make lint to avoid cpplint-related travis failures (or also run make lint -- I forgot a lot until I added the pre-commit hook)

+1, thank you

Merged -- note you should be able to self-assign JIRAs now

…litate unit testing Several things in this patch * Adds PageReader abstraction, and a SerializedPageReader implementation according to the Parquet file format * Adds a MockPageReader and a couple unit tests demonstrating end-to-end test without creating a Parquet file * Adds a DataPageBuilder test fixture tool, may become part of the main write path later * Adds PlainEncoder implementation for a few primitive types * Fixes a few ColumnReader bugs exposed by the unit tests Author: Wes McKinney <wes@cloudera.com> Closesapache#32 from wesm/PARQUET-485 and squashes the following commits: aa33078 [Wes McKinney] Fix function doc e897a81 [Wes McKinney] Restore NumRequiredBits function after rebase ee4d97a [Wes McKinney] Change PageReader::NextPage API to return shared_ptr<Page>(nullptr) on eos 0324021 [Wes McKinney] Clarify some comments ec871c4 [Wes McKinney] Add include guards e63bbdd [Wes McKinney] Move vector_equal to util/test-common.h 44a78a1 [Wes McKinney] Refactor to decouple page deserialization from column reader so that mock data pages cna be constructed in unit tests.

Requires PARQUET-485 (apache#32) The boolean Encoding::PLAIN code path was using RleDecoder, inconsistent with other implementations of Parquet. This patch adds an implementation of plain encoding and uses BitReader instead of RleDecoder to decode plain-encoded boolean data. Unit tests to verify. Also closes PR apache#12. Thanks to @edani for reporting. Author: Wes McKinney <wes@cloudera.com> Closesapache#34 from wesm/PARQUET-454 and squashes the following commits: 01cb5a7 [Wes McKinney] Use a seed in the data generation 0bf5d8a [Wes McKinney] Fix inconsistencies with boolean PLAIN encoding. Change-Id: I1be5252c654d4864d14c3cdd70d63c507e0a9403

This PR enables tests for `ARROW_COMPUTE`, `ARROW_DATASET`, `ARROW_FILESYSTEM`, `ARROW_HDFS`, `ARROW_ORC`, and `ARROW_IPC` (default on). #7131 enabled a minimal set of tests as a starting point. I confirmed that these tests pass locally with the current master. In the current TravisCI environment, we cannot see this result due to a lot of error messages in `arrow-utility-test`. ``` $ git log | head -1 commit ed5f534 % ctest ...
