Eventually this will hopefully be a good step towards using the `backtrace` crate directly from crates.io itself, but we're not quite there yet! Hopefully this is a small incremental first step we can take. 2018-05-30T12:58:23+00:00 Alex Crichton alex@alexcrichton.com 2018-05-23T02:40:02+00:00 urn:sha1:7c14a54bc81d8e259b43ac8077f2e851c7769753 While we're at it update the `backtrace` crate from crates.io. It turns out that the submodule's configure script has gotten a lot more finnicky as of late so also switch over to using the `cc` crate manually which allows to avoid some hacks around the configure script as well 2018-05-30T12:58:20+00:00 Alex Crichton alex@alexcrichton.com 2018-05-27T20:02:34+00:00 urn:sha1:1402a106bd66b88750f3cd255eb77451c3f432e6 2018-02-10T11:22:57+00:00 Matthias Krüger matthias.krueger@famsik.de 2018-02-10T11:22:57+00:00 urn:sha1:7ee3e39f640a9532842e1441bf6bc98893b6a3ba 2017-11-21T14:33:45+00:00 Martin Lindhe martin-commit@ubique.se 2017-11-21T14:33:45+00:00 urn:sha1:ece9a57d1b6e10ef2ad1dffd19fd6033cdc760ee 2017-11-08T10:28:17+00:00 John Colanduoni john@colanduoni.com 2017-11-08T10:28:17+00:00 urn:sha1:8581b59fb39b0072665de59b1a70e708b251d4b0 Fixes #45731 libbacktrace uses mmap if available to map ranges of the files containing debug information. On macOS `mmap` will succeed even if the mapped range does not exist, and a SIGBUS (with an unusual EXC_BAD_ACCESS code 10) will occur when the program attempts to page in the memory. To combat this we force `libbacktrace` to be built with the simple `read` based fallback on Apple platforms. 2017-10-25T14:51:36+00:00 Alex Crichton alex@alexcrichton.com 2017-10-25T14:51:36+00:00 urn:sha1:2f3c412c84712f2159ccf5c174ac716d19925d68 This is sort of a long overdue change from the investigation in #29293 and #37477. The released binaries of rustc don't have debug information and so don't actively suffer this problem but this can hit local development of rustc and also larger programs compiled against libstd generating backtraces. The main purpose of the mmap allocator in libacktrace is to be usable from a signal handler, but we don't do that, so the normal allocator using malloc/free should work well for us. 2017-09-05T00:41:43+00:00 kennytm kennytm@gmail.com 2017-09-03T16:52:31+00:00 urn:sha1:aa6bd117bbe05930476b4aec1001fff77ce66348 2017-09-01T19:24:16+00:00 John Colanduoni john@colanduoni.com 2017-07-23T18:48:55+00:00 urn:sha1:e3de40e72f0f6b2dba54388d05e94e2c145cec6d 2017-09-01T19:24:15+00:00 John Colanduoni john@colanduoni.com 2017-07-23T06:05:47+00:00 urn:sha1:e8121b3d163f90a8f1cefca07352d3780eed933d
