Improve CSV.Rows performance
* Added some code comments to help clarify things * Update out-dated variable name usage (e.g. tapes) * Cleaned up dependencies (WeakRefStrings is test-only now) * Added lots of tests to increase coverage * Made multithreaded chunk identification more robust by checking we have correct # of columns for 5 consecutive rows instead of just 1 * Made sure we sync Int64 sentinels in multithreaded parsing * Removed some unused functions * Made sure we're testing type promoting when multithreaded parsing * Add a `tasks::Integer` keyword argument to allow controlling how many tasks will be spawned for multithreaded parsing * Clean up keyword arg docs
Lots of cleanup
Add CSV.Chunks for iterating over chunks of large files
Fixes #464 (or at least improves it quite a bit). A new precompile.jl file is a script I ran to get some precompile statements for CSV.jl, Parsers.jl, and SentinelArrays.jl (which seem to be the biggest targets and ones that live in JuliaData). The Parsers.jl output ended up being insignificant for now, so that wasn't committed, but SentinelArrays.jl was. I've added two new "precompile.csv" and "precompile_small.csv" files that are used for snooping; they include a column of each type, which should hopefully cover a good chunk of codepaths we're compiling. We can ajust more later if there are certain paths that could use it and are causing people problems. All in all, this cuts TTFP (time-to-first-parse) in half on my machine.
Add some precompiles
Fixes #668. The issue here is that when column names were passed manually, the code path that "skipped" to the datarow passed in the starting position as 1 instead of `pos` variable. This used to not be an issue because the `pos` was almost always 1 anyway. With `IOBuffer`, we now start `pos` at `io.ptr`, so we'll have more cases where it's critical to start reading at right position.
When column names passed manually, ensure we respect starting position
I've wanted to do this for a while; previously we were only using the estimate from the first 10 rows. This hooks into the "chunking" code, which looks at `tasks` # of chunks of a file to find the start of rows for each; we now keep track of the # of bytes we saw when doing those row checks and use those totals plus the original 10 rows to form a better estimate of the total # of rows.
Improve accuracy of estimated rows for multithreaded parsing
Make the automatic pooled=>string column promotion more efficient
added documentation for the dateformats option
Fixes #679; alternative fix to #681. When a column is dropped, we essentially turn it into a `Missing` column type and ignore it when parsing. There was a check later in file parsing, however, that said if no missing values were found in a column, to ensure its type is `Vector{T}` instead of `Vector{Union{Missing, T}}`. The core problem in issue #679 was that these dropped columns, while completely `missing`, didn't get "flagged" as having `missing` values.
Fixes #680. Before custom types, the `typemap` keyword argument was really only about mapping between the standard, supported types. With custom types, we still only support certain type mappings (Int to Float, Any type to String), but we also want to support type mappings like `Int64 => Int32`. This PR readjusts how typemap works when detecting column types to account for the possiblity of custom Integer or AbstractFloat type mappints for Int64 & Float64, and moving directly to String if that's specified.
Ensure dropped columns are ignored in later file processing
