checkpoint 1.0.1 (2022-01-08)

• Maintainer change (Folashade Daniel; [email protected]).

checkpoint 1.0.0 (2021-06-14)

This is a major refactoring/rewrite of checkpoint, aimed at solving many long-standing issues.

• Switch to pkgdepends for the backend, replacing custom-written code that calls install.packages and the like. This brings the following benefits:
  • Caching of downloaded packages.
  • Allow installing packages which are in use, without having to unload them first.
  • Comprehensive reporting of all aspects of the install process: dependency resolution, creating an install plan, downloading packages, and actual installation.
  • Reliable detection of installation outcomes (no more having to screen-scrape the R terminal!)
• New functions create_checkpoint and use_checkpoint, reflecting the two main objectives of the package. The checkpoint function calls out to these, based on whether the checkpoint directory exists.
  • A side-effect of this is that calling checkpoint in your home directory should result in checkpointing very many packages only once.
• New functions uncheckpoint (which is the reverse of use_checkpoint), delete_checkpoint and delete_all_checkpoints to manage checkpointing. They replace checkpointRemove, checkpointArchives and unCheckpoint.
• Function getValidSnapshots renamed to list_mran_snapshots to clarify that it lists the snapshots on the MRAN server. Similarly, setSnapshot renamed to use_mran_snapshot for consistency with other function names.
• Function scanForPackages renamed to scan_project_files to match grammatical pattern of other function names; now automatically includes rmarkdown (not knitr) in the list of dependencies if Rmarkdown-based files are found.
• Experimental support for a checkpoint.yml manifest file, to specify packages to include or exclude.
  • Allows including packages from Bioconductor or GitHub in the checkpoint; it's recommended to specify a version number, tag or commit hash to ensure you always get the same version of a package.
• Consistent use of snake_case for all object names and function arguments.
• Remove obsolete code to handle lack of HTTPS support in ancient versions of R. (Note that the MRAN site now requires HTTPS.)
• Other bug fixes and general tidying.

checkpoint 0.4.10 (2020-10-29)

• Maintainer change (Michelle Wallig; [email protected]).

checkpoint 0.4.9 (2020-02-23)

• Make vignettes static to avoid CRAN check issues.

checkpoint 0.4.8 (2020-01-13)

• Added a use.lock argument to checkpoint. When this is FALSE, packages are installed without the use of locks (via the --no-lock argument to R CMD INSTALL). The default is TRUE, which is needed to pass checks on R-devel; set this to FALSE to replicate the previous behaviour of checkpoint.
• Fix build failures with the main checkpoint vignette on R-devel.
• Restored Andrie de Vries and Microsoft to Authors@R in the DESCRIPTION file.

checkpoint 0.4.7 (2019-09-08)

• Fixes for bugs uncovered by R CMD check.
• unCheckpoint now automatically restores library paths to their pre-checkpoint state. This fixes the bug where library paths specified by means other than the R_LIBS_USER environment variable, eg via code in .Rprofile, were not restored. The new argument is no longer used, and a warning is printed if it is supplied.
• Skip all tests on CRAN, to avoid issues when MRAN is down.
• Handle an empty local MRAN gracefully (#253).
