Dirk Eddelbuettel: Rcpp 1.0.6: Some Updates

rcpp logo The Rcpp team is proud to announce release 1.0.6 of Rcpp which arrived at CRAN earlier today, and has been uploaded to Debian too. Windows and macOS builds should appear at CRAN in the next few days. This marks the first release on the new six-months cycle announced with release 1.0.5 in July. As reminder, interim dev or rc releases will often be available in the Rcpp drat repo; this cycle there were four. Rcpp has become the most popular way of enhancing R with C or C++ code. As of today, 2174 packages on CRAN depend on Rcpp for making analytical code go faster and further (which is an 8.5% increase just since the last release), along with 207 in BioConductor. This release features six different pull requests from five different contributors, mostly fixing fairly small corner cases, plus some minor polish on documentation and continuous integration. Before releasing we once again made numerous reverse dependency checks none of which revealed any issues. So the passage at CRAN was pretty quick despite the large dependency footprint, and we are once again grateful for all the work the CRAN maintainers do.

Changes in Rcpp patch release version 1.0.6 (2021-01-14)
  • Changes in Rcpp API:
    • Replace remaining few uses of EXTPTR_PTR with R_ExternalPtrAddr (Kevin in #1098 fixing #1097).
    • Add push_back and push_front for DataFrame (Walter Somerville in #1099 fixing #1094).
    • Remove a misleading-to-wrong comment (Mattias Ellert in #1109 cleaning up after #1049).
    • Address a sanitizer report by initializing two private bool variables (Benjamin Christoffersen in #1113).
    • External pointer finalizer toggle default values were corrected to true (Dirk in #1115).
  • Changes in Rcpp Documentation:
    • Several URLs were updated to https and/or new addresses (Dirk).
  • Changes in Rcpp Deployment:
    • Added GitHub Actions CI using the same container-based setup used previously, and also carried code coverage over (Dirk in #1128).
  • Changes in Rcpp support functions:
    • Rcpp.package.skeleton() avoids warning from R. (Dirk)

Thanks to my CRANberries, you can also look at a diff to the previous release. Questions, comments etc should go to the rcpp-devel mailing list off the R-Forge page. Bugs reports are welcome at the GitHub issue tracker as well (where one can also search among open or closed issues); questions are also welcome under rcpp tag at StackOverflow which also allows searching among the (currently) 2616 previous questions. If you like this or other open-source work I do, you can sponsor me at GitHub. My sincere thanks to my current sponsors for me keeping me caffeinated.

Dirk Eddelbuettel: Rcpp 1.0.5: Several Updates

rcpp logo Right on the heels of the news of 2000 CRAN packages using Rcpp (and also hitting 12.5 of CRAN package, or one in eight), we are happy to announce release 1.0.5 of Rcpp. Since the ten-year anniversary and the 1.0.0 release release in November 2018, we have been sticking to a four-month release cycle. The last release has, however, left us with a particularly bad taste due to some rather peculiar interactions with a very small (but ever so vocal) portion of the user base. So going forward, we will change two things. First off, we reiterate that we have already made rolling releases. Each minor snapshot of the main git branch gets a point releases. Between release 1.0.4 and this 1.0.5 release, there were in fact twelve of those. Each and every one of these was made available via the drat repo, and we will continue to do so going forward. Releases to CRAN, however, are real work. If they then end up with as much nonsense as the last release 1.0.4, we think it is appropriate to slow things down some more so we intend to now switch to a six-months cycle. As mentioned, interim releases are always just one install.packages() call with a properly set repos argument away. Rcpp has become the most popular way of enhancing R with C or C++ code. As of today, 2002 packages on CRAN depend on Rcpp for making analytical code go faster and further, along with 203 in BioConductor. And per the (partial) logs of CRAN downloads, we are running steady at around one millions downloads per month. This release features again a number of different pull requests by different contributors covering the full range of API improvements, attributes enhancements, changes to Sugar and helper functions, extended documentation as well as continuous integration deplayment. See the list below for details.

Changes in Rcpp patch release version 1.0.5 (2020-07-01)
  • Changes in Rcpp API:
    • The exception handler code in #1043 was updated to ensure proper include behavior (Kevin in #1047 fixing #1046).
    • A missing Rcpp_list6 definition was added to support R 3.3.* builds (Davis Vaughan in #1049 fixing #1048).
    • Missing Rcpp_list 2,3,4,5 definition were added to the Rcpp namespace (Dirk in #1054 fixing #1053).
    • A further updated corrected the header include and provided a missing else branch (Mattias Ellert in #1055).
    • Two more assignments are protected with Rcpp::Shield (Dirk in #1059).
    • One call to abs is now properly namespaced with std:: (Uwe Korn in #1069).
    • String object memory preservation was corrected/simplified (Kevin in #1082).
  • Changes in Rcpp Attributes:
    • Empty strings are not passed to R CMD SHLIB which was seen with R 4.0.0 on Windows (Kevin in #1062 fixing #1061).
    • The short_file_name() helper function is safer with respect to temporaries (Kevin in #1067 fixing #1066, and #1071 fixing #1070).
  • Changes in Rcpp Sugar:
    • Two sample() objects are now standard vectors and not R_alloc created (Dirk in #1075 fixing #1074).
  • Changes in Rcpp support functions:
    • Rcpp.package.skeleton() adjusts for a (documented) change in R 4.0.0 (Dirk in #1088 fixing #1087).
  • Changes in Rcpp Documentation:
    • The pdf file of the earlier introduction is again typeset with bibliographic information (Dirk).
    • A new vignette describing how to package C++ libraries has been added (Dirk in #1078 fixing #1077).
  • Changes in Rcpp Deployment:
    • Travis CI unit tests now run a matrix over the versions of R also tested at CRAN (rel/dev/oldrel/oldoldrel), and coverage runs in parallel for a net speed-up (Dirk in #1056 and #1057).
    • The exceptions test is now partially skipped on Solaris as it already is on Windows (Dirk in #1065).
    • The default CI runner was upgraded to R 4.0.0 (Dirk).
    • The CI matrix spans R 3.5, 3.6, r-release and r-devel (Dirk).

Thanks to CRANberries, you can also look at a diff to the previous release. Questions, comments etc should go to the rcpp-devel mailing list off the R-Forge page.

Dirk Eddelbuettel: Rcpp 1.0.4.6: Bug fix interim version

rcpp logo Rcpp 1.0.4 was released on March 17, following the usual sequence of fairly involved reverse-depends check along with a call for community testing issued weeks before the release. In that email I specifically pleaded with folks to pretty-please test non-standard setups:
It would be particularly beneficial if those with unsual build dependencies tested it as we would increase overall coverage beyond what I get from testing against 1800+ CRAN packages. BioConductor would also be welcome.
Alas, you can t always get what you want. Shortly after the release we were made aware that the two (large) pull request at the book ends of the 1.0.3 to 1.0.4 release period created trouble. Of these two, the earliest PR in the 1.0.4 release upset older-than-CRAN-tested installation, i.e. R 3.3.0 or before. (Why you d want to run R 3.3.* when R 3.6.3 is current is something I will never understand, but so be it.) This got addressed in two new PRs. And the matching last PR had a bit of sloppyness leaving just about everyone alone, but not all those macbook-wearing data scientists when using newer macOS SDKs not used by CRAN. In other words, unsual setups. But boy, do those folks have an ability to complain. Again, two quick PRs later that was addressed. Along came a minor PR with two more Rcpp::Shield<> uses (as life is too short to manually count PROTECT and UNPROTECT). And then a real issue between R 4.0.0 and Rcpp first noticed with RcppParallel builds on Windows but then also affecting RcppArmadillo. Another quickly issued fix. So by now the count is up to six, and we arrived at Rcpp 1.0.4.6. Which is now on CRAN, after having sat there for nearly a full week, and of course with no reason given. Because the powers that be move in mysterious ways. And don t answer to earthlings like us. As may transpire here, I am little tired from all this. I think we can do better, and I think we damn well should, or I may as well throw in the towel and just release to the drat repo where each of the six interim versions was available for all to take as soon as it materialized. Anyway, here is the state of things. Rcpp has become the most popular way of enhancing R with C or C++ code. As of today, 1897 packages on CRAN depend on Rcpp for making analytical code go faster and further, along with 191 in BioConductor. And per the (partial) logs of CRAN downloads, we are running steasy at one millions downloads per month. The changes for this interim version are summarized below.

Changes in Rcpp patch release version 1.0.4.6 (2020-04-02)
  • Changes in Rcpp API:
    • The exception handler code in #1043 was updated to ensure proper include behavior (Kevin in #1047 fixing #1046).
    • A missing Rcpp_list6 definition was added to support R 3.3.* builds (Davis Vaughan in #1049 fixing #1048).

Dirk Eddelbuettel: RInside 0.2.14

A new release 0.2.14 of RInside is now on CRAN and in Debian. RInside provides a set of convenience classes which facilitate embedding of R inside of C++ applications and programs, using the classes and functions provided by Rcpp. It has been nearly two years since the last release, and a number of nice extensions, build robustifications and fixes had been submitted over this period---see below for more. The only larger and visible extension is both a new example and some corresponding internal changes to allow a readline prompt in an RInside application, should you desire it. RInside is stressing the CRAN system a little in that it triggers a number of NOTE and WARNING messages. Some of these are par for the course as we get close to R internals not all of which are "officially" in the API. This lead to the submission sitting a little longer than usual in incoming queue. Going forward we may need to find a way to either sanction these access point, whitelist them or, as a last resort, take the package off CRAN. Time will tell. Changes since the last release were:

Changes in RInside version 0.2.14 (2017-04-28)
  • Interactive mode can use readline REPL ( ukasz aniewski-Wo k in #25, and Dirk in #26)
  • Windows macros checks now uses _WIN32 (Kevin Ushey in #22)
  • The wt example now links with libboost_system
  • The Makevars file is now more robist (Mattias Ellert in #21)
  • A problem with empty environment variable definitions on Windows was addressed (Jeroen Ooms in #17 addressing #16)
  • HAVE_UINTPTR_T is defined only if not already defined
  • Travis CI is now driven via run.sh from our forked r-travis

CRANberries also provides a short report with changes from the previous release. More information is on the RInside page. Questions, comments etc should go to the rcpp-devel mailing list off the Rcpp R-Forge page, or to issues tickets at the GitHub repo.

Dirk Eddelbuettel: littler 0.3.1

max-heap image The second release of littler as a CRAN package is now available, following in the now more than ten-year history as a package started by Jeff in the summer of 2006, and joined by me a few weeks later. littler is the first command-line interface for R and predates Rscript. It is still faster, and in my very biased eyes better as it allows for piping as well shebang scripting via #!, uses command-line arguments more consistently and still starts faster. It prefers to live on Linux and Unix, has its difficulties on the OS X due yet-another-braindeadedness there (who ever thought case-insensitive filesystems where a good idea?) and simply does not exist on Windows (yet -- the build system could be extended -- see RInside for an existence proof, and volunteers welcome!). This release brings us fixes and enhancements from three other contributors, a couple new example scripts, more robust builds, extended documentation and more -- see below for details. The NEWS file entry is below.
Changes in littler version 0.3.1 (2016-08-06)
  • Changes in examples
    • install2.r now passes on extra options past -- to R CMD INSTALL (PR #37 by Steven Pav)
    • Added rcc.r to run rcmdcheck::rcmdcheck()
    • Added (still simple) render.r to render (R)markdown
    • Several examples now support the -x or --usage flag to show extended help.
  • Changes in build system
    • The AM_LDFLAGS variable is now set and used too (PR #38 by Mattias Ellert)
    • Three more directories, used when an explicit installation directory is set, are excluded (also #38 by Mattias)
    • Travis CI is now driven via run.sh from our fork, and deploys all packages as .deb binaries using our PPA where needed
  • Changes in package
    • SystemRequirements now mentions the need for libR, i.e. an R built with a shared library so that we can embed R.
    • The docopt and rcmdcheck packages are now suggested, and added to the Travis installation.
    • A new helper function r() is now provided and exported so that the package can be imported (closes #40).
    • URL and BugReports links were added to DESCRIPTION.
  • Changes in documentation
    • The help output for installGithub.r was corrected (PR #39 by Brandon Bertelsen)
Full details for the littler release are provided as usual at the ChangeLog page. The code is available via the GitHub repo, from tarballs off my littler page and the local directory here -- and now of course all from its CRAN page and via install.packages("littler"). Binary packages are available directly in Debian as well as soon via Ubuntu binaries at CRAN thanks to the tireless Michael Rutter. will probably have new Comments and suggestions are welcome at the GitHub repo.

Lunar: Reproducible builds: week 44 in Stretch cycle

What happened in the reproducible builds effort between February 21th and February 27th:

Toolchain fixes Didier Raboud uploaded pyppd/1.0.2-4 which makes PPD generation deterministic. Emmanuel Bourg uploaded plexus-maven-plugin/1.3.8-10 which sorts the components in the components.xml files generated by the plugin. Guillem Jover has implemented stable ordering for members of the control archives in .debs. Chris Lamb submitted another patch to improve reproducibility of files generated by cython.

Packages fixed The following packages have become reproducible due to changes in their build dependencies: dctrl-tools, debian-edu, dvdwizard, dymo-cups-drivers, ekg2, epson-inkjet-printer-escpr, expeyes, fades, foomatic-db, galternatives, gnuradio, gpodder, gutenprint icewm, invesalius, jodconverter-cli latex-mk, libiio, libimobiledevice, libmcrypt, libopendbx, lives, lttnganalyses, m2300w, microdc2, navit, po4a, ptouch-driver, pxljr, tasksel, tilda, vdr-plugin-infosatepg, xaos. The following packages became reproducible after getting fixed: Some uploads fixed some reproducibility issues, but not all of them:

tests.reproducible-builds.org The reproducibly tests for Debian now vary the provider of /bin/sh between bash and dash. (Reiner Herrmann)

diffoscope development diffoscope version 50 was released on February 27th. It adds a new comparator for PostScript files, makes the directory tests pass on slower hardware, and line ordering variations in .deb md5sums files will not be hidden anymore. Version 51 uploaded the next day re-added test data missing from the previous tarball. diffoscope is looking for a new primary maintainer.

Package reviews 87 reviews have been removed, 61 added and 43 updated in the previous week. New issues: captures_shell_variable_in_autofoo_script, varying_ordering_in_data_tar_gz_or_control_tar_gz. 30 new FTBFS have been reported by Chris Lamb, Antonio Terceiro, Aaron M. Ucko, Michael Tautschnig, and Tobias Frost.

Misc. The release team reported on their discussion about the topic of rebuilding all of Stretch to make it self-contained (in respect to reproducibility). Christian Boltz is hoping someone could talk about reproducible builds at the openSUSE conference happening June 22nd-26th in N rnberg, Germany.

Lunar: Reproducible builds: week 33 in Stretch cycle

What happened in the reproducible builds effort between December 6th and December 12th: Toolchain fixes Reiner Herrmann rebased our experimental version of doxygen on version 1.8.9.1-6. Chris Lamb submitted a patch to make the manpages generated by ruby-ronn reproducible by using the locale-agnostic %Y-%m-%d for the dates. Daniel Kahn Gillmor took another shot at the issue of source path captured in DWARF symbols. A patch has been sent for review by GCC upstream to add the ability to read an environment variable with -fdebug-prefix-map. Packages fixed The following 24 packages have become reproducible due to changes in their build dependencies: gkeyfile-sharp, gprbuild, graphmonkey, gthumb, haskell-yi-language, ion, jackson-databind, jackson-dataformat-smile, jackson-dataformat-xml, jnr-ffi, libcommons-net-java, libproxy, maven-shared-utils, monodevelop-database, mydumper, ndesk-dbus, nini, notify-sharp, pixz, protozero, python-rtslib-fb, slurm-llnl, taglib-sharp, tomboy-latex. The following packages became reproducible after getting fixed: Some uploads fixed some reproducibility issues, but not all of them: These uploads might have fixed reproducibility issues but could not be tested yet: Patches submitted which have not made their way to the archive yet: reproducible.debian.net Files created with diffoscope now have diffoscope in their name instead debbindiff. (h01ger) Hostnames of first and second build node are now recorded and shown in the build history. (Mattia Rizzolo) Exchanges have started with F-Droid developers to better understand what would be required to test F-Droid applications. (h01ger) A first small set of Fedora 23 packages is now also being tested while development on a new framework for testing RPMs in general has begun. A new Jenkins job has been added to set up to mock, the build system used by Fedora. Another new job takes care of testing RPMs from Fedora 23 on x86_64. So far only 151 packages from the buildsys-build group are tested (currently all unreproducible), but the plan is to build all 17,000 source packages in Fedora 23 and rawhide. The page presenting the results should also soon be improved. (h01ger, Dhiru Kholia) For Arch Linux, all 2223 packages from the extra repository will also be tested from now on. Packages in extra" are tested every four weeks, while those from core every week. Statistics are now displayed alongside the results. (h01ger) jenkins.debian.net has been updated to jenkins-job-builder version 1.3.0. Many job configurations have been simplified and refactored using features of the new version. This was another milestone for the jenkins.debian.org migration. (Phil Hands, h01ger) diffoscope development Chris Lamb announced try.diffoscope.org: an online service that runs diffoscope on user provided files. Screenshot of try.diffoscope.org Improvements are welcome. The application is licensed under the AGPLv3. On diffoscope itself, most pending patches have now been merged. Expect a release soon! Most of the code implementing parallel processing has been polished. Sadly, unpacking archive is CPU-bound in most cases, so the current thread-only implementation does not offer much gain on big packages. More work is still require to also add concurrent processes. Documentation update Ximin Luo has started to write a specification for buildinfo files that could become a larger platform than the limited set of features that were thought so far for Debian .buildinfo. Package reviews 113 reviews have been removed, 111 added and 56 updated in the previous week. 42 new FTBFS bugs were opened by Chris Lamb and Niko Tyni. New issues identified this week: timestamps_in_documentation_generated_by_docbook_dbtimestamp, timestamps_in_sym_l_files_generated_by_malaga, timestamps_in_edj_files_generated_by_edje_cc. Misc. Chris Lamb presented reproducible builds at skroutz.gr.

Lunar: Reproducible builds: week 17 in Stretch cycle

A good amount of the Debian reproducible builds team had the chance to enjoy face-to-face interactions during DebConf15.
Names in red and blue were all present at DebConf15
Picture of the  reproducible builds  talk during DebConf15
Hugging people with whom one has been working tirelessly for months gives a lot of warm-fuzzy feelings. Several recorded and hallway discussions paved the way to solve the remaining issues to get reproducible builds part of Debian proper. Both talks from the Debian Project Leader and the release team mentioned the effort as important for the future of Debian. A forty-five minutes talk presented the state of the reproducible builds effort. It was then followed by an hour long roundtable to discuss current blockers regarding dpkg, .buildinfo and their integration in the archive. Picture of the  reproducible builds  roundtable during DebConf15 Toolchain fixes Reiner Herrmann submitted a patch to make rdfind sort the processed files before doing any operation. Chris Lamb proposed a new patch for wheel implementing support for SOURCE_DATE_EPOCH instead of the custom WHEEL_FORCE_TIMESTAMP. akira sent one making man2html SOURCE_DATE_EPOCH aware. St phane Glondu reported that dpkg-source would not respect tarball permissions when unpacking under a umask of 002. After hours of iterative testing during the DebConf workshop, Sandro Knau created a test case showing how pdflatex output can be non-deterministic with some PNG files. Packages fixed The following 65 packages became reproducible due to changes in their build dependencies: alacarte, arbtt, bullet, ccfits, commons-daemon, crack-attack, d-conf, ejabberd-contrib, erlang-bear, erlang-cherly, erlang-cowlib, erlang-folsom, erlang-goldrush, erlang-ibrowse, erlang-jiffy, erlang-lager, erlang-lhttpc, erlang-meck, erlang-p1-cache-tab, erlang-p1-iconv, erlang-p1-logger, erlang-p1-mysql, erlang-p1-pam, erlang-p1-pgsql, erlang-p1-sip, erlang-p1-stringprep, erlang-p1-stun, erlang-p1-tls, erlang-p1-utils, erlang-p1-xml, erlang-p1-yaml, erlang-p1-zlib, erlang-ranch, erlang-redis-client, erlang-uuid, freecontact, givaro, glade, gnome-shell, gupnp, gvfs, htseq, jags, jana, knot, libconfig, libkolab, libmatio, libvsqlitepp, mpmath, octave-zenity, openigtlink, paman, pisa, pynifti, qof, ruby-blankslate, ruby-xml-simple, timingframework, trace-cmd, tsung, wings3d, xdg-user-dirs, xz-utils, zpspell. The following packages became reproducible after getting fixed: Uploads that might have fixed reproducibility issues: Some uploads fixed some reproducibility issues but not all of them: Patches submitted which have not made their way to the archive yet: St phane Glondu reported two issues regarding embedded build date in omake and cduce. Aur lien Jarno submitted a fix for the breakage of make-dfsg test suite. As binutils now creates deterministic libraries by default, Aur lien's patch makes use of a wrapper to give the U flag to ar. Reiner Herrmann reported an issue with pound which embeds random dhparams in its code during the build. Better solutions are yet to be found. reproducible.debian.net Package pages on reproducible.debian.net now have a new layout improving readability designed by Mattia Rizzolo, h01ger, and Ulrike. The navigation is now on the left as vertical space is more valuable nowadays. armhf is now enabled on all pages except the dashboard. Actual tests on armhf are expected to start shortly. (Mattia Rizzolo, h01ger) The limit on how many packages people can schedule using the reschedule script on Alioth has been bumped to 200. (h01ger) mod_rewrite is now used instead of JavaScript for the form in the dashboard. (h01ger) Following the rename of the software, debbindiff has mostly been replaced by either diffoscope or differences in generated HTML and IRC notification output. Connections to UDD have been made more robust. (Mattia Rizzolo) diffoscope development diffoscope version 31 was released on August 21st. This version improves fuzzy-matching by using the tlsh algorithm instead of ssdeep. New command line options are available: --max-diff-input-lines and --max-diff-block-lines to override limits on diff input and output (Reiner Herrmann), --debugger to dump the user into pdb in case of crashes (Mattia Rizzolo). jar archives should now be detected properly (Reiner Herrman). Several general code cleanups were also done by Chris Lamb. strip-nondeterminism development Andrew Ayer released strip-nondeterminism version 0.010-1. Java properties file in jar should now be detected more accurately. A missing dependency spotted by St phane Glondu has been added. Testing directory ordering issues: disorderfs During the reproducible builds workshop at DebConf, participants identified that we were still short of a good way to test variations on filesystem behaviors (e.g. file ordering or disk usage). Andrew Ayer took a couple of hours to create disorderfs. Based on FUSE, disorderfs in an overlay filesystem that will mount the content of a directory at another location. For this first version, it will make the order in which files appear in a directory random. Documentation update Dhole documented how to implement support for SOURCE_DATE_EPOCH in Python, bash, Makefiles, CMake, and C. Chris Lamb started to convert the wiki page describing SOURCE_DATE_EPOCH into a Freedesktop-like specification in the hope that it will convince more upstream to adopt it. Package reviews 44 reviews have been removed, 192 added and 77 updated this week. New issues identified this week: locale_dependent_order_in_devlibs_depends, randomness_in_ocaml_startup_files, randomness_in_ocaml_packed_libraries, randomness_in_ocaml_custom_executables, undeterministic_symlinking_by_rdfind, random_build_path_by_golang_compiler, and images_in_pdf_generated_by_latex. 117 new FTBFS bugs have been reported by Chris Lamb, Chris West (Faux), and Niko Tyni. Misc. Some reproducibility issues might face us very late. Chris Lamb noticed that the test suite for python-pykmip was now failing because its test certificates have expired. Let's hope no packages are hiding a certificate valid for 10 years somewhere in their source! Pictures courtesy and copyright of Debian's own paparazzi: Aigars Mahinovs.
