How strong is PropertyTree JSON support
by Michael Powell 09 Jan '19

09 Jan '19

Hello, I have a requirement to support parsing JSON, and while I could potentially pull together a Spirit Qi (or even X3, possibly) based grammar, I wonder with all the idiosyncrasies, i.e. particularly strings, escape sequences, Unicode, etc, is it worth it. Then there's the Boost.PropertyTree JSON support, which I think may be an adequate fit. However, just how robust is this support when it comes to handling some of the nuanced corner cases? The harder ones I think are the potential for escape sequences, Unicode, etc, embedded within a String. i.e. https://json.org/ or, http://es5.github.io/x7.html It seems with Property Tree there are also these limitations: <docs> The property tree dataset is not typed, and does not support arrays as such. Thus, the following JSON / property tree mapping is used: * JSON objects are mapped to nodes. Each property is a child node. * JSON arrays are mapped to nodes. Each element is a child node with an empty name. If a node has both named and unnamed child nodes, it cannot be mapped to a JSON representation. * JSON values are mapped to nodes containing the value. However, all type information is lost; numbers, as well as the literals "null", "true" and "false" are simply mapped to their string form. * Property tree nodes containing both child nodes and data cannot be mapped. </docs> It seems to me that much of the limitation is in adapting the PropertyTree to the JSON structure, but mostly vice versa. Not quite fitting a square peg in a round hole, but coming quite close, I think: "If a node has both named and unnamed child nodes, it cannot be mapped to a JSON representation." We're talking about the mapping from PropertyTree to JSON here? Seems like a potentially problematic issue depending on desired usage, 'all type information is lost; numbers, as well as the literals "null", "true" and "false" are simply mapped to their string form'. I'm not sure what "nodes containing both child nodes and data" means? https://www.boost.org/doc/libs/1_69_0/doc/html/property_tree/parsers.html#p… Besides these concerns, I should think a grammar is fairly straightforward to construct, if push came to shove. It's either living with the Boost.PropertyTree or rolling my own AST, which is not outside the realm of possibility for my purposes. Thoughts? Suggestions? Thanks! Michael Powell

Boost wiki - revised Boost guidance for authors on Warnings - RFC
by Paul A. Bristow 08 Jan '19

08 Jan '19

As promised at the end of a long (hijacked!) thread on 'Warnings' http://boost.2283326.n4.nabble.com/Current-Guidance-on-Compiler-Warnings-td… starting from a query by Brian Kuhl of Wind River on Boost's policy on compiler warnings, I have spent some time revising the previous guidance document on Trac that I edited many years ago. This was a long and tedious task as Markdown, as most conveniently used on Github, is rather different from the mark-up language on Trac, leaving me slightly in fumble mode :-( I have made some updates en passant, but there is still much to do updating for the much improved granularity of warning suppression and perhaps more about other code improvement tools like Lint, UBSan. The overall structure leaves a lot to be desired, but I don't want to put any more work into this without some encouragement that it will prove useful. I have posted the result of my efforts on https://github.com/boostorg/boost/wiki/Guidelines:-Warnings and I am as promised I am starting this new thread on warning for your comments, corrections, condemnations etc. HTH Paul --- Paul A.

[Solaris 11] wrong RUNPATH after install
by Dechaux Eric CEN (BCQ STIG) 07 Jan '19

Hello, I am building boost 1.69 on a Solaris 11.4 x86_64 box. After installation the shared libraries keep the boost dependencies from the build directory. The build log is without error and attached, ldd output is the following : :/usr/local/lib$ ldd libboost_*.so.1.69.0 libboost_chrono.so.1.69.0: bin.v2/libs/system/build/gcc-7.3.0/release/threading-multi/visibility-hidden/libboost_system.so.1.69.0 => (file not found) libstdc++.so.6 => /usr/lib/64/libstdc++.so.6 libm.so.2 => /lib/64/libm.so.2 librt.so.1 => /lib/64/librt.so.1 libgcc_s.so.1 => /usr/lib/64/libgcc_s.so.1 libpthread.so.1 => /lib/64/libpthread.so.1 libc.so.1 => /lib/64/libc.so.1 libboost_context.so.1.69.0: libstdc++.so.6 => /usr/lib/64/libstdc++.so.6 libm.so.2 => /lib/64/libm.so.2 librt.so.1 => /lib/64/librt.so.1 libgcc_s.so.1 => /usr/lib/64/libgcc_s.so.1 libpthread.so.1 => /lib/64/libpthread.so.1 libc.so.1 => /lib/64/libc.so.1 libboost_coroutine.so.1.69.0: bin.v2/libs/context/build/gcc-7.3.0/release/threading-multi/visibility-hidden/libboost_context.so.1.69.0 => (file not found) bin.v2/libs/thread/build/gcc-7.3.0/release/threadapi-pthread/threading-multi/visibility-hidden/libboost_thread.so.1.69.0 => (file not found) bin.v2/libs/chrono/build/gcc-7.3.0/release/threading-multi/visibility-hidden/libboost_chrono.so.1.69.0 => (file not found) bin.v2/libs/system/build/gcc-7.3.0/release/threading-multi/visibility-hidden/libboost_system.so.1.69.0 => (file not found) libstdc++.so.6 => /usr/lib/64/libstdc++.so.6 libm.so.2 => /lib/64/libm.so.2 librt.so.1 => /lib/64/librt.so.1 libgcc_s.so.1 => /usr/lib/64/libgcc_s.so.1 libpthread.so.1 => /lib/64/libpthread.so.1 libc.so.1 => /lib/64/libc.so.1 libboost_system.so.1.69.0: libstdc++.so.6 => /usr/lib/64/libstdc++.so.6 libm.so.2 => /lib/64/libm.so.2 librt.so.1 => /lib/64/librt.so.1 libgcc_s.so.1 => /usr/lib/64/libgcc_s.so.1 libpthread.so.1 => /lib/64/libpthread.so.1 libc.so.1 => /lib/64/libc.so.1 libboost_thread.so.1.69.0: bin.v2/libs/system/build/gcc-7.3.0/release/threading-multi/visibility-hidden/libboost_system.so.1.69.0 => (file not found) libstdc++.so.6 => /usr/lib/64/libstdc++.so.6 libm.so.2 => /lib/64/libm.so.2 librt.so.1 => /lib/64/librt.so.1 libgcc_s.so.1 => /usr/lib/64/libgcc_s.so.1 libpthread.so.1 => /lib/64/libpthread.so.1 libc.so.1 => /lib/64/libc.so.1 As a result I can't move the library on another box without changing the RUNPATH on the .so files with elfedit. I tried to build each library on it own but the final result is the same. What can I do ?

Re: [Boost-users] I ran b2 with the -d+2 command and redirected the output to a file

My project-config.jam file has quotes where needed, so that's not a problem. That file isn't the problem, but probably the commands I'm running are. I'll try to see if I can get it to work without Stacktrace. ________________________________ From: Osman Zakir <osmanzakir90(a)hotmail.com> Sent: Saturday, January 5, 2019 8:50 PM To: degski Subject: Re: [Boost-users] I ran b2 with the -d+2 command and redirected the output to a file I'll just build Boost with MSVC then, for now.

That won't help you, though [as I already gave you all the info]. Getting boost to build with clang-cl has been a long-term process [I've been pushing this for close to 2 years]. It only (mostly) works since [important work, boost 1.69] has been done by Peter Dimov (relatively recent)]. You really should dig into the archives to see what progress has been made (https://lists.boost.org/Archives/boost/2018/11/244235.php, but there are many more posts), not all might be perfect yet, we are on the bleeding edge here. The whole thing of building boost with clang-cl [as clang-cl itself, which is part of the problem, while at the same time MSVC is in significant flux as well] is a WIP (work in progress), so you cannot expect things to be perfect [yet, but the commitment is there (of all parties involved) and I am sure it will be good at some point in the (near?) future]. degski -- “If something cannot go on forever, it will stop" - Herbert Stein

Okay, so what commands did you use when building, then? When it also built Stacktrace. And could you also try with version 1.69.0 and let me know how that turns out? ________________________________ From: degski <degski(a)gmail.com> Sent: Saturday, January 5, 2019 6:40 PM To: Osman Zakir Subject: Re: [Boost-users] I ran b2 with the -d+2 command and redirected the output to a file On Sat, 5 Jan 2019 at 15:37, degski <degski(a)gmail.com<mailto:degski@gmail.com>> wrote: You need something like libboost_stacktrace_windbg_cached-vc141-mt-sgd-1_65_1.lib and libboost_stacktrace_windbg-vc141-mt-sgd-1_65_1.lib [but then for 1.69 of course and the release builds as well]. Whether that is relevant to you is for you to decide.

The Stacktrace libs I have are: "libboost_stacktrace_noop-clangw8-mt-d-x32-1_69.lib", "libboost_stacktrace_noop-clangw8-mt-d-x64-1_69.lib", "libboost_stacktrace_noop-clangw8-mt-x32-1_69.lib", and "libboost_stacktrace_noop-clangw8-mt-x64-1_69.lib" Should I have two more of the Stacktrace libs, or is this fine? As I said in my previous message, the first error actually comes from Boost.Stacktrace and it says: "error: no member named 'GetModuleFileNameA' in namespace 'boost::winapi'; did you mean simply 'GetModuleFileNameA'?". I also still need help on this issue I opened in the Boost.Asio GitHub: https://github.com/boostorg/asio/issues/184 .

This is a follow-up to the message where I asked for help about a failed attempt to build Boost. I ran b2 with the -d+2 command in addition to the other commands and also redirected the output to a file. It's attached to this message, as well as the project-config.jam file.
