When run with "ulimit -s unlimited", the misc/cgo/test test binary finds a stack size of 0x3000 returned by getcontext, causing the runtime to try to stay within those bounds and then fault when called back in the test after 64 kB has been used by C. I suspect that Solaris is doing something clever like reporting the current stack size and growing the stack as faults happen. On all the other systems, getcontext reports the maximum stack size. And when the ulimit is not unlimited, even Solaris reports the maximum stack size. Work around this by assuming that any stack on Solaris must be at least 1 MB. Fixes #12210.

This is an example of converting an old HTTP/1-only test to test against both HTTP/1 and HTTP/2. Please send more of these! Also, for comparing the http.Transport's responses between HTTP/1 and HTTP/2, see clientserver_test.go's h12Compare type and tests using h12Compare. Sometimes that's the more appropriate option.

- change way of protection from O(N^2) on duplicate values. Previous algorithm does additional comparisons and swaps on every split pass. Changed algorithm does one ordinal quicksort split pass, and if distribution is skewed, then additional pass to separate pivot's duplicates. Changed algorithm could be slower on very ununique slice, but it is still protected from O(N^2). - increase small slice size and do simple shell sort pass to amortize worst case on small slices. Small slice has higher probability to have skewed distribution, so lets sort it with simpler algorithm. benchmark old ns/op new ns/op delta BenchmarkSortString1K 458374 388641 -15.21% BenchmarkSortInt1K 217851 181796 -16.55% BenchmarkSortInt64K 20539264 16730340 -18.54% BenchmarkSort1e2 98668 95554 -3.16% BenchmarkSort1e4 20278500 18316829 -9.67% BenchmarkSort1e6 3215724392 2795999911 -13.05% number of operations: Size: Total: Swap: Less: % % % Sort 100 Avg -5.98% -18.43% -1.90% Sort 100 Max -14.43% -16.02% -4.51% Sort 300 Avg -7.50% -12.76% -5.96% Sort 300 Max -11.29% -9.60% -4.30% Sort 1000 Avg -12.13% -11.65% -12.25% Sort 1000 Max -13.81% -11.77% -11.89% Sort 3000 Avg -14.61% -9.30% -15.86% Sort 3000 Max -15.81% -8.66% -15.19% Sort 10000 Avg -16.10% -8.47% -17.80% Sort 10000 Max -17.13% -7.63% -16.97% Sort 30000 Avg -17.46% -7.56% -19.57% Sort 30000 Max -18.24% -7.62% -17.68% Sort 100000 Avg -18.83% -6.64% -21.33% Sort 100000 Max -19.72% -6.70% -20.96% Sort 300000 Avg -19.61% -6.16% -22.30% Sort 300000 Max -20.69% -6.15% -21.81% Sort 1000000 Avg -20.42% -5.58% -23.31% Sort 1000000 Max -21.54% -5.56% -23.61% Change-Id: I23868e8b52b5841b358cd5403967c9a97871e4d5 Reviewed-on: https://go-review.googlesource.com/15688Reviewed-by: -

This adds support for compressed ELF sections. This compression is treated as a framing issue and hence the package APIs all transparently decompress compressed sections. This requires some subtlety for (*Section).Open, which returns an io.ReadSeeker: since the decompressed data comes from an io.Reader, this commit introduces a Reader-to-ReadSeeker adapter that is efficient for common uses of Seek and does what it can otherwise. Fixes #11773. Change-Id: Ic0cb7255a85cadf4c1d15fb563d5a2e89dbd3c36 Reviewed-on: https://go-review.googlesource.com/17341Reviewed-by:

GCC and LLVM support zlib-compressing DWARF debug sections (and there's some evidence that this may be happening by default in some circumstances now). Add support for reading compressed DWARF sections. Since ELF relocations apply to the decompressed data, decompression is done before applying relocations. Since relcations are applied by debug/elf, decompression must also be handled there. Note that this is different from compressed ELF sections, which is a more general mechanism used by very recent versions of GCC. Updates #11773.

stackBarrier on amd64 sanity checks that it's unwinding the correct entry in the stack barrier array. However, this check is wrong in two ways that make it unlikely to catch anything, right or wrong: 1) It checks that savedLRPtr == SP, but, in fact, it should be that savedLRPtr+8 == SP because the RET that returned to stackBarrier popped the saved LR. However, we didn't notice this check was wrong because, 2) the sense of the conditional branch is also wrong. Fix both of these.
