In proffer: Profile R Code and Visualize with 'Pprof'

proffer 0.1.6

• Fix path.expand() error when printing the port number (#30, @HenrikBengtsson).
• Use parallelly::freePort() to drive random_port() (#31, @HenrikBengtsson).
• Add the -no_browser flag to the pprof call to avoid redundant browsers.
• Update go link and go version (1.19.5).

proffer 0.1.5

• Skip all tests on CRAN. When I submitted version 0.1.4, in the CRAN incoming pretests on 64-bit Windows R-devel (2021-07-25 r80663), the unit tests took 24 minutes to run. This length of time is certainly egregious, but I do no have access to the precise configuration of CRAN's machines, and I cannot reproduce the issue on R hub, Win Builder, or GitHub Actions. In all these latter services, the total check time is 1-2 minutes.

proffer 0.1.4

• Choose the flame graph as the default view.

proffer 0.1.3

• Reduce check time of examples.

proffer 0.1.2

• Remove superfluous operator %||%.
• Skip Go installation tests on CRAN.

proffer 0.1.1

• Address a CRAN check error for R-devel on Windows: lengthen the time of a test to avoid empty protocol buffers.
• Build site with GitHub Actions and use flatly theme (#26, @krlmlr).
• Ping port until pprof is initialized (#28).
• Improve console messages of host and port.
• Forward error message if pprof process quits early.

proffer 0.1.0

• pprof() passes ... to record_pprof() (#12, @krlmlr).
• In the DESCRIPTION, unquote function names and add parentheses afterwards. (CRAN comments for next submission.)
• Motivate profilers more in the README.
• Increase font size in logo.
• Search systems for pprof if the pprof_path env var is not set (#14, @krlmlr).
• Use PROFFER_PPROF_BIN env var instead of pprof_path (#11, @krlmlr). pprof_path is still back-compatibly supported.
• Introduce new environment variables PROFFER_GO_BIN and PROFFER_GRAPHVIZ_BIN to allow the user to set the paths to the respective binaries (#11, @krlmlr).
• Add a new pprof_sitrep() function to give a situation report of the pprof installation, its dependencies, and their environment variables (#17, @krlmlr).
• Add new function test_pprof().

proffer 0.0.2

• Respond to CRAN feedback on version 0.0.1. Software and API names in the DESCRIPTION now appear in single quotes, the grammatical errors are gone, and new links reference the methodological background and context of proffer (https://github.com/google/pprof, https://developers.google.com/protocol-buffers, and https://github.com/r-prof/profile).
• Use processx instead of callr (#5, @gaborcsardi).
• Add Graphviz installation instructions.
• Add pprof and Graphviz as system requirements.

proffer 0.0.1

• First version.
