Long unnamed bench_expr expressions are now
truncated correctly when used as columns of a tibble (#94).
bench_mark tibbles now respect the knitr paged df
option (#103).
Fixed an issue where macOS specific C code paths were accidentally being used on GNU Hurd (#118).
Fixed -Wstrict-prototypes warnings, as requested by
CRAN (#124).
R >=3.5.0 is now required, which is aligned with tidyverse standards.
bench now uses testthat 3e (#129).
bench no longer Suggests mockery.
Davis Vaughan is now the maintainer.
autoplot.bench_mark() again supports factor levels
for expression, as intended (#82)
bench::mark() and bench::workout() no
longer support unquote and splice operators. This fixes inconsistencies
in performance results with functions like rlang::list2()
(#61).
bench has been re-licensed as MIT (#101).
mark() columns memory, result and mem_alloc columns are
now always included, even if they are unused.New bench_process_memory() function, to return the
current and maximum memory used by the current process. This uses system
functions to track memory, so can measure memory outside of R’s GC
heap.
New workout_expressions() function, a low-level
function to workout a list of expressions, like those obtained via
parse() from a file.
mark() gains a memory argument to
control if it records memory allocations, set
memory = FALSE to disable recording memory allocations,
which can be helpful when trying to benchmark long pieces of code with
many allocations (#62).
mark() now permits empty arguments, e.g. accidental
trailing commas (#61).
mark() now errors correctly when the expressions
deparsed length is different.
bench_expr objects now work better with the upcoming
versions of tibble and vctrs (@romainfrancois, #64)
autoplot.bench_mark() provides a more informative
error if the ggbeeswarm package is not installed (@coatless, #69).
Update documentation of bench_mark columns (@jdblischak,
#67).
bench_memory() examples no longer fail if they are
run with R that does not have memory profiling capability
(#56).
bench_expr now has a class of
c("bench_expr", "list") rather than
c("bench_expr", "expression"), as it is really a list of
calls rather than a true expression object.

summary.bench_mark() gains a time_unit
argument, so you can report all times in a consistent scale if desired
(#18, #26).
bench_mark() now checks for user interrupts, to
allow you to stop benchmarking if it takes longer than you were
expecting (#49).
New bench_memory() to capture just the memory
allocated by an expression.
bench_time() is now an alias for
system_time().
unnest.bench_mark() is now compatible with the
upcoming tidyr 1.0.0 (#48, #51)
New hires_time() allows you to explicitly capture
high resolution time points.
workout() a new function which makes timing multiple
expressions in turn simpler.
mark() now internally uses a tempfile rather than a
textConnection, as the latter has a 100,000 character limit on some
platforms (#27)
mark() no longer returns the mean or max values and
the column order has been tweaked to try and put the most interesting
columns first (#37)
Errors during evaluation now halt execution (#28, #43)
scale_bench_time() and
scale_bench_bytes() now allow you to use a non-logarithmic
scale.
