filearray 0.1.8
- Fixed a bug where
C++
errors are not correctly thrown
due to a recent Rcpp
update. This bug may cause erroneous
code to execute ignoring try-catch statement and imbalanced protecting
stacks (fwhich
, mapreduce
)
filearray 0.1.7
- Removed non-API R C interface
- Allows
subsetAssign
to assign when value length is 1
(thanks @talegari
issue #9
)
- Allows more flexible
fwhich
function with functional
val
input and options to include corresponding values as
part of return (thanks @talegari
issue
#10
)
- Fixed
mapreduce
bug when partition length is way larger
than the buffer size, causing buffer to stop updating
- Fixed other
C++
issues, such as unused buffer
allocation in subset-assign, and min_
offset in
sub_vec_range
. These issues are not considered bugs since
they don’t affect the results, but the performance is slightly increased
after fix.
- Replaced
dipsaus
with more updated
ravetools
in the vignette performance profiling
- Updated examples to get rid of warning messages and out-dated
arguments.
filearray 0.1.6
- Removed
c++11
from system requirement and
Makevars
- Used
TinyThreads
instead of OpenMP
to get
parallel working on OSX
- Added
as_filearray
method, and support optional
float
- Added array proxy class, allowing arrays to lazy-evaluate simple
operators
- Allows user-defined temporary file array path
- Fixed
fmap
issues, using better guesses for default
.input_size
- Fixed a memory bug caused when partition margin has elements greater
than 1 and when
FARR_subset_sequential
is used
- Used
fastmap
to avoid environment look-up
fa_eval_ops
allows dimension names
- Larger default buffer size to allow
2^20
in single
partition
- Disabled single indexing
- Fixed
endian
issue on big-endian
platforms
filearray 0.1.5
- Fixed a bug when trying to read array data sequentially. The bug is
caused by buffer size being greater than the array length, making in a
pointer that controls the partition number exceed the end of vector,
resulting in undefined behavior. The functions affected are:
fmap
, fmap2
. The bug has been fixed and passed
valgrind
memory check.
filearray 0.1.4
- Fixed a bug when allocated memory is one byte short than requested.
The bug would crash R when triggered in certain cases.
- Removed limit to the maximum number of partitions when writing. The
previous implementation creates and opens related file descriptors all
at once before writing. This setup will raise errors when the number of
connections reach to certain limit, often defined by the operating
systems. This update only opens the connection on demand. The
performance might be impacted when writing to disk, but in return, the
program will be more robust
- Fixed
subset
function environment not resolved
correctly when using formula
- Added
filearray_load_or_create
as an alternative to
filearray_checkload
by automatically replace existing
obsolete array files if the headers, dimensions, or data types don’t
match. Also on_missing
argument is provided to allow array
initialization if new array is created.
filearray 0.1.3
- Automatically detect whether symbolic-link works and show
warnings
- Warnings can be suppressed
- Allow extra headers to be set in
meta
file
- Added header signature method
- Fixed symbolic-link issues on
Windows
when partition
sizes are 0
- Added check-load function
filearray_checkload
to
validate header
- Fixed collapse method when
dimnames
are set
- Fixed an unprotected variable in
C++
code
filearray_bind
can use cache if the header signatures
agree
filearray_bind
can choose to force overwrite
- Added package
digest
to Imports
- Fixed a typo and several small bugs
filearray 0.1.2
- Removed
flush
in saving data to let system decide when
to flush to hard drive
- Allowed array to expand along the partition margin
- Fixed dimension name getting dropped under certain situations
- Use 2 cores by default when
R CMD check
is
detected
filearray 0.1.1
- Added
OpenMP
flag in the MakeVars
- Fixed critical bugs that could cause
segfaults
- Can store
complex
and float
data
types
- Re-implemented read/write functions to use memory map
- Allowed
dimnames
to be set
- Added generics
subset
to subset using
dimnames
- Added vignette to compare performance
- Added speed comparisons in
README.md
- Added
collapse
to calculate marginal summation with
little memory overhead
- Added
fmap
, fmap2
to apply functions to
one or multiple file arrays with little memory overhead (also very
fast)
- Fixed ‘unprotected’ issues warned by
rchk
filearray 0.1.0
- Added a
NEWS.md
file to track changes to the
package.
- Initial implementation
