Changelog

v0.6.6

replaced most signed integers with unsigned

v0.6.5

works on Python 3.10 and 3.11
fixed warnings about signed to unsigned comparison

v0.6.4

fixed a bug with slicing chunks in VarlenSeries
added extra comparison operators for VarlenEntry
added sync to VarlenSeries
fixed a bug with not propagating metadata write exceptions
fixed a bug with Database treating varlen and metadata as real time series

v0.6.3

v0.6

bugfix: fixed some bugs with reading values after close
added support for storing metadata as minijson
- this will be enabled by default is minijson is importable
fixed minor compiler warnings
TimeSeries.iterate_range will accept a parameter called direct_bytes for compatibility with VarlenSeries. It's value is ignored
more class constructors use explicit typing - faster tempsdb
TimeSeries.get_current_value will correctly raise ValueError instead of returning None

v0.5.4

older TempsDB databases that do not support varlens will be updated upon opening
added metadata support for databases
a flush will be done before re-enabling mmap
bugfix to read archive data

v0.5.3

added disable_mmap, enable_mmap and open_chunks_mmap_size into VarlenSeries

v0.5.2

added multiple properties and attributes to VarlenSeries

v0.5.1

added VarlenSeries.close_chunks
Database.sync will now return 0
indexed-gzip proved to be a poor choice, dropped
setup.py fixed

v0.5

if mmap is used, the kernel will be informed after loading the chunk that we don't need it's memory right now
deleting a TimeSeries will now correctly return a zero
both Database, TimeSeries and Chunk destructor will close and emit a warning if the user forgot to
if page_size is default, it won't be written as part of the metadata
added support for per-series metadata
following additions to Database:
- delete_series
- delete_varlen_series
following additions to TimeSeries:
- added append_padded
- added metadata support, metadata property and set_metadata call
added variable length series
added experimental support for gzipping time series
fixed a bug where getting a series that was already closed would TypeError
following additions to Chunk:
- get_slice_of_piece_at
- get_slice_of_piece_starting_at
- get_byte_of_piece
- get_timestamp_at
fixed the behaviour of AlternativeMMaps when passed a single index to getitem and setitem
added StillOpen exception, chunk won't allow to close itself if it has any remaining references

v0.4.4

more error conditions during mmap will be supported as well
ENOMEM will be correctly handled during resize operation
added TimeSeries.descriptor_based_access
added Chunk.switch_to_mmap_based_access

v0.4.3

improving handling mmap failures on too low memory
slightly reduced metadata.txt by defaulting page_size
moved Chunk
added support for gzipping
added DirectChunk
iterating and writing at the same time from multiple threads made safe
added TimeSeries.disable_mmap
Iterator's destructor will emit a warning if you forget to close it explicitly.
added option for transparent gzip compression Please note that gzip disables mmap!
experimental gzip support for constant-length time series

v0.4.2

empty series will return an Iterator
bugfix release fixed Database.create_series
Database constructor will throw if no database is there
changed Iterator.next to Iterator.next_item, synce Cython guys said to not implement the method next on iterators.
