Boost N-Dimensional Array Library
by pencilcaseman＠gmail.com 28 Apr '21

28 Apr '21

Hi All, Would there be any interest in an n-dimensional array library for boost? There is Boost.MultiArray library, but as far as I can tell, this only supports containing the arrays, not performing arithmetic on them. It would provide an interface similar to what Numpy provides, would be fully templated and might, if possible, support BLAS routines to accelerate the functions. Thanks, Toby

[ci][security] Codecov security breach
by Andrey Semashev 27 Apr '21

27 Apr '21

Hi, I found this in my news feed today: The codecov-bash script that is used to upload codecov reports from CI to codecov.io was maliciously modified to collect sensitive information and send to a third party server. Things like private keys, credentials, auth tokens used in the CI might be compromised. https://discuss.hashicorp.com/t/hcsec-2021-12-codecov-security-event-and-ha… https://about.codecov.io/security-update/ I'm not using codecov, and I have vague understanding how it works, but I've seen it used in Boost libraries' CI. I don't know if they are affected, this is an FYI to the maintainers.

---------- Forwarded message --------- From: sayan chaudhuri <sayanchaudhuri758(a)gmail.com> Date: Sat, Apr 24, 2021 at 3:08 PM Subject: [BOOST][GIL][Histogram]Ordered Maps in place of unordered maps To: <boost-gil(a)lists.boost.org> Dear Matseuz, The histogram implemented in boost gil uses an unordered map.Wont it have been better with an ordered map? Because the worst case time complexity is better in case of ordered maps. Regards, Yours sincerely, Sayan Chaudhuri

[Boost][Multiarray]Move for_each.hpp from examples to boost/multi_array
by sayan chaudhuri 25 Apr '21

25 Apr '21

Hello Everyone, I wish to draw attention to the fact that the for_each header file for multiarrays in boost is not present in the include/boost section of the boost multiarray repository. Also, the header file does not have a namespace defined inside it and so the compiler becomes confused as to which for_each function to follow, the one from stl or this one. The for_each is a great utility for boost multiarrays reducing code size and increasing readability. I would like to what others would like to say about these changes. Making these changes allows contributors to other boost libraries to use that functionality in a proper manner. Thanking everyone, Yours sincerely, Sayan Chaudhuri

[iostreams] [build] Why do iostream tests link against static libraries ?
by Brian Kuhl 22 Apr '21

22 Apr '21

Cross-posting since boost-build is quiet these days. I’m trying to get iostreams working with shared libraries on VxWorks The tests will compile with clang 11 if I comment out the forced dependency on static libraries But I’d like to understand the reason for forcing a link of static libraries with a dynamic executable? https://github.com/boostorg/iostreams/blob/4d2e763ba8b88f3350fbea29b54507a3… rule test-iostreams ( sources * : requirements * : target-name ? ) { return [ run $(sources) /boost/test//boost_unit_test_framework # /<link>static /boost/filesystem//boost_filesystem # /<link>static : # command : # input files : # build requirements <toolset>msvc:<define>_CRT_SECURE_NO_DEPRECATE <toolset>msvc:<define>_SCL_SECURE_NO_DEPRECATE <toolset>cw-9.3,<os>darwin:<runtime-link>static <define>BOOST_IOSTREAMS_NO_LIB <link>shared:<define>BOOST_IOSTREAMS_DYN_LINK=1 $(requirements) : $(target-name) ] ; } If I don’t comment, I get a link error.

Reminder: BinTray is shutting down 1-May
by Marshall Clow 21 Apr '21

21 Apr '21

Bintray is “sunsetting” on the 1st of May. At that time, you will be unable to download boost releases from there. Before that time, their service will be occasionally interrupted. We will be updating the web site before then, but the new location is: https://boostorg.jfrog.io/artifactory/main/release/ <https://boostorg.jfrog.io/artifactory/main/release/> So instead of downloading from: https://dl.bintray.com/boostorg/release/1.76.0/source/boost_1_76_0.tar.gz You should download from: https://boostorg.jfrog.io/artifactory/main/release/1.76.0/source/boost_1_76… This applies to all releases from 1.63.0 onward — Marshall
