In pkgcache: Cache 'CRAN'-Like Metadata and R Packages

pkgcache 2.2.0

• New pkg.current_platform option and PKG_CURRENT_PLATFORM environment variable to override the detected platform.

• In repo_add() and repo_resolve() the MRAN@ prefix is now deprecated and resolves to PPM, because MRAN will be retired soon. See more at https://posit.co/blog/migrating-from-mran-to-posit-package-manager/.

• The metadata cache now has SystemRequirements information for Bioconductor packages.

pkgcache 2.1.1

• parse_installed() now has a packages argument, to list only a subset of all packages.

• parse_packages() can now parse PACKAGES files with trailing whitespace (#93).

• The Bioconductor repositories now include the 'books' repository, available since Bioconductor 3.12.

pkgcache 2.1.0

• pkgcache now supports binary packages on x86_64 macOS and R 4.3.0 and later (#89).

• Better Posit Package Manager (PPM) support. New ppm_has_binaries(), ppm_r_versions(), ppm_repo_url(), ppm_snapshots() and ppm_platforms() functions to help interacting with PPM. See the new 'pkgcache and Posit Package Manager on Linux' article at https://r-lib.github.io/pkgcache. (#47 and r-lib/pkgdepends#186).

pkgcache 2.0.4

• Update R version -> Bioconductor version mapping. R 4.2.x now maps to Bioconductor 3.16.

pkgcache 2.0.3

• The built and sysreqs columns of the metadata case are always character vectors now, and not logicals, as it used to be in some edges cases in the past.

• The deps column of the metadata cache is not a tibble any more, but a data frame with a tbl class, as it should be.

• cran_archive_*() functions now only download the metadata if it is newer than what you have currently.

• cran_archive_cleanup() now does not ignore the force argument.

• The sources column in the metadata cache now has the correct URL for packages in the CRAN archive (https://github.com/r-lib/pak/issues/425).

pkgcache 2.0.2

• pkgcache error messages are better now.

• pkgcache now does not compress the metadata cache files, which makes loading the metadata cache faster.

pkgcache 2.0.1

No user visible changes.

pkgcache 2.0.0

BREAKING CHANGE

• Starting from version 2.0.0 pkgcache returns data frames instead of tibbles. While data frames and tibbles are very similar, they are not completely compatible. To convert the output of pkgcache to tibbles call the as_tibble() function on them.

pkgcache loads the pillar package at startup, if available, and uses it to improve the printing of pkgcache data frames.

OTHER CHANGES

• parse_packages() now automatically determines the type of the PACKAGES* file, instead of relying on file extensions.

• pkgcache can now call back again to a PACKAGES file if PACKAGES.gz is not available. (This fixes a regression in pkgcache 1.3.0.)

• pkgcache now uses HTTP 1.1 on Linux as well, because of crashes with HTTP/2.

• pkgcache now supports file:///, repositories, i.e. repositories on the local file system.

pkgcache 1.3.0

• pkgcache now works better on M1 macs.

• current_r_platform() does a much better job now. In particular, on Linux it includes the name and release of the distribution. The new current_r_platform_data() function returns the platform information as a data frame, instead of a single string.

• Metadata is now more accurate for Windows packages that are typically not multi-arch any more on R 4.2.0 (current R-devel).

• pkgcache has its own DCF metadata parser now, which is much faster, and it parses all fields of PACAKGES* and DESCRIPTION files.

• New parse_installed() function to get the metadata of all installed packages in a library. It uses the new DCF parser, so it is quite fast.

• meta_cache_list() and related functions now correctly set the rversion column of source R packages to "*".

• pkgcache now uses HTTP 1.1 on macOS, to work around a possible slowdown issue with libcurl for HTTP/2.

• pkgcache now uses our extra metadata (file sizes, system requirements, etc.) for RStudio Package Manager (RSPM) repositories as well, as long as they are named RSPM in getOption("repos").

pkgcache 1.2.2

• The default location of the cache has changed to align with the standard tools::R_user_dir() cache location. To clean up your old cache call pkgcache:::cleanup_old_cache_dir().

pkgcache 1.2.1

No user visible changes.

pkgcache 1.2.0

• New repo_add(), repo_get(), repo_resolve() and with_repo() functions to query and manipulate repositories.

• meta_cache_*() functions now handle getOption("repos") changes correctly.

• Failed metadata downloads now do not trigger metadata updates (#52).

• New bioc_release_version(), bioc_devel_version(), bioc_repos() helper functions to deal with Bioconductor repositories.

• Metadata cache functions, e.g. meta_cache_deps() etc. now allow specifying the dependency types in all lowercase (#54).

pkgcache 1.1.1

• package_cache now does not fail if the web server does not send an Etag header when downloading packages.

• package_cache has now much relaxed HTTP timeouts, and handles downloading many packages (slowly) much better.

• The package download progress bar can now be suppressed by setting the pkg.show_progress option to FALSE.

pkgcache 1.1.0

• New repo_status() function to query the status and response time of CRAN-like repositories.

• New bioc_version() and bioc_version_map() functions to query Bioconductor repositories.

• pkgcache now does not fail if some repositories do not provide some package types.

• New current_r_platform(), default_cran_mirror() and default_platforms() functions.

• pkgcache now works for R 4.0.x macOS binaries.

pkgcache 1.0.7

• Metadata is now cached in RDS version 2 formats, so metadata written by newer R version can be used by older R versions as well (#36).

pkgcache 1.0.6

• HTTP timeouts are now much better, and by default they are defined in terms of download speed, instead of total download time (#29).

• pkgcache now tries to download metadata from the PACKAGES file, if it cannot find PACKAGES.gz (@timmsm, #27).

• pkgcache is now less verbose when updating or loading metadata.

pkgcache 1.0.5

• Fix a bug in the download functions, that broke pak downloads.

pkgcache 1.0.4

• Fix handling of Bioconductor versions and repositories, see README for the details.

• Now different versions of pkgcache, that potentially have different metadata format, can share the same metadata cache directory.

pkgcache 1.0.3

• Fix concurrency issues when the async API is used multiple times in the same event loop.

• Make package compatible with tibble >= 2.0.0.

• Add meta_cache_summary() and a summary() method for cranlike_metadata_cache. Return information about a metadata cache instance.

pkgcache 1.0.2

• First public release
