…h call so that network progress is what's measured

I like it.

A minor problem is that since the progress bar doesn't know how much data will be sent, it doesn't show actual progress (i.e. a percentage). But I've applied it anyway since it doesn't hurt to have.

Ever since SQLite in Nixpkgs was updated to 3.8.0.2, Nix has randomly segfaulted on Darwin: http://hydra.nixos.org/build/6175515 http://hydra.nixos.org/build/6611038 It turns out that this is because the binary cache substituter somehow ends up loading two versions of SQLite: the one in Nixpkgs and the other from /usr/lib/libsqlite3.dylib. It's not exactly clear why the latter is loaded, but it appears to be because WWW::Curl indirectly loads /System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation, which in turn seems to load /usr/lib/libsqlite3.dylib. This leads to a segfault when Perl exits: #0 0x00000001010375f4 in sqlite3_finalize () #1 0x000000010125806e in sqlite_st_destroy () #2 0x000000010124bc30 in XS_DBD__SQLite__st_DESTROY () #3 0x00000001001c8155 in XS_DBI_dispatch () ... #14 0x0000000100023224 in perl_destruct () #15 0x0000000100000d6a in main () ... The workaround is to explicitly load DBD::SQLite before WWW::Curl.

this was caused by the use of std::chrono::duration::max() which gets multiplied by some ratio to calculate nanoseconds to wait. then, it explodes because that is a signed integer overflow. this was definitely a bug. error below: /nix/store/fdiknsmnnczx6brsbppyljcs9hqckawk-gcc-12.3.0/include/c++/12.3.0/bits/chrono.h:225:38: runtime error: signed integer overflow: 9223372036854775807 * 1000000 cannot be represented in type 'long' #0 0x736d376b2b69 in std::chrono::duration<long, std::ratio<1l, 1000000000l>> std::chrono::__duration_cast_impl<std::chrono: :duration<long, std::ratio<1l, 1000000000l>>, std::ratio<1000000l, 1l>, long, false, true>::__cast<long, std::ratio<1l, 1000l>>( std::chrono::duration<long, std::ratio<1l, 1000l>> const&) /nix/store/fdiknsmnnczx6brsbppyljcs9hqckawk-gcc-12.3.0/include/c++/12 .3.0/bits/chrono.h:225:38 NixOS#1 0x736d376b2b69 in std::enable_if<__is_duration<std::chrono::duration<long, std::ratio<1l, 1000000000l>>>::value, std::chr ono::duration<long, std::ratio<1l, 1000000000l>>>::type std::chrono::duration_cast<std::chrono::duration<long, std::ratio<1l, 10 00000000l>>, long, std::ratio<1l, 1000l>>(std::chrono::duration<long, std::ratio<1l, 1000l>> const&) /nix/store/fdiknsmnnczx6brs bppyljcs9hqckawk-gcc-12.3.0/include/c++/12.3.0/bits/chrono.h:270:9 NixOS#2 0x736d376b2b69 in std::enable_if<__is_duration<std::chrono::duration<long, std::ratio<1l, 1000000000l>>>::value, std::chr ono::duration<long, std::ratio<1l, 1000000000l>>>::type std::chrono::ceil<std::chrono::duration<long, std::ratio<1l, 1000000000l >>, long, std::ratio<1l, 1000l>>(std::chrono::duration<long, std::ratio<1l, 1000l>> const&) /nix/store/fdiknsmnnczx6brsbppyljcs9 hqckawk-gcc-12.3.0/include/c++/12.3.0/bits/chrono.h:386:14 NixOS#3 0x736d376b2b69 in std::cv_status std::condition_variable::wait_for<long, std::ratio<1l, 1000l>>(std::unique_lock<std::mut ex>&, std::chrono::duration<long, std::ratio<1l, 1000l>> const&) /nix/store/fdiknsmnnczx6brsbppyljcs9hqckawk-gcc-12.3.0/include/ c++/12.3.0/condition_variable:164:6 NixOS#4 0x736d376b1ee9 in std::cv_status nix::Sync<nix::ProgressBar::State, std::mutex>::Lock::wait_for<long, std::ratio<1l, 1000 l>>(std::condition_variable&, std::chrono::duration<long, std::ratio<1l, 1000l>> const&) /home/jade/lix/lix/src/libutil/sync.hh: 65:23 NixOS#5 0x736d376b1ee9 in nix::ProgressBar::ProgressBar(bool)::'lambda'()::operator()() const /home/jade/lix/lix/src/libmain/prog ress-bar.cc:99:27 NixOS#6 0x736d36de25c2 in execute_native_thread_routine (/nix/store/a3zlvnswi1p8cg7i9w4lpnvaankc7dxx-gcc-12.3.0-lib/lib/libstdc++ .so.6+0xe05c2) NixOS#7 0x736d36b6b0e3 in start_thread (/nix/store/1zy01hjzwvvia6h9dq5xar88v77fgh9x-glibc-2.38-44/lib/libc.so.6+0x8b0e3) (BuildId : 287831bffdbdde0ec25dbd021d12bdfc0ab9f5ff) NixOS#8 0x736d36bed5e3 in __clone (/nix/store/1zy01hjzwvvia6h9dq5xar88v77fgh9x-glibc-2.38-44/lib/libc.so.6+0x10d5e3) (BuildId: 28 7831bffdbdde0ec25dbd021d12bdfc0ab9f5ff) SUMMARY: UndefinedBehaviorSanitizer: undefined-behavior /nix/store/fdiknsmnnczx6brsbppyljcs9hqckawk-gcc-12.3.0/include/c++/12.3. 0/bits/chrono.h:225:38 in Change-Id: Ia0303242cdfd5d49385ae9e99718d709625a4633

Fixup propose-release: don't puke if the version number didn't change

This was removed in #11152.

We don't scan coroutine stacks, because currently they don't have GC roots (there is no evaluation happening in coroutines). So there is currently no need to restore the other parts of the original patch, such as BoehmGCStackAllocator.
