      time: Fix missing colon when formatting time zone offsets with seconds · 298c623e
      Joel Stemmer authored
      When formatting time zone offsets with seconds using the stdISO8601Colon
      and stdNumColon layouts, the colon was missing between the hour and minute
      parts.
      
      Fixes #8497.

      runtime: bump MaxGcprocs to 32 · 44106a08
      Dmitriy Vyukov authored
      There was a number of improvements related to GC parallelization:
      1. Parallel roots/stacks scanning.
      2. Parallel stack shrinking.
      3. Per-thread workbuf caches.
      4. Workset reduction.
      Currently 32 threads work well.

      runtime: fix data race in stackalloc · d6d7170d
      Dmitriy Vyukov authored
      Stack shrinking happens during mark phase,
      and it assumes that it owns stackcache in mcache.
      Stack cache flushing also happens during mark phase,
      and it accesses stackcache's w/o any synchronization.
      This leads to stackcache corruption:

      syscall: ignore EINVAL/ENOENT from readdirent on OS X 10.10 · a83bbc9c
      Russ Cox authored
      On OS X 10.10 Yosemite, if you have a directory that can be returned
      in a single getdirentries64 call (for example, a directory with one file),
      and you read from the directory at EOF twice, you get EOF both times:
              fd = open("dir")
              getdirentries64(fd) returns data
              getdirentries64(fd) returns 0 (EOF)
              getdirentries64(fd) returns 0 (EOF)
      
      But if you remove the file in the middle between the two calls, the
      second call returns an error instead.
              fd = open("dir")
              getdirentries64(fd) returns data
              getdirentries64(fd) returns 0 (EOF)
              remove("dir/file")
              getdirentries64(fd) returns ENOENT/EINVAL
      
      Whether you get ENOENT or EINVAL depends on exactly what was
      in the directory. It is deterministic, just data-dependent.
      
      This only happens in small directories. A directory containing more data
      than fits in a 4k getdirentries64 call will return EOF correctly.
      (It's not clear if the criteria is that the directory be split across multiple
      getdirentries64 calls or that it be split across multiple file system blocks.)
      
      We could change package os to avoid the second read at EOF,
      and maybe we should, but that's a bit involved.
      For now, treat the EINVAL/ENOENT as EOF.
      
      With this CL, all.bash passes on my MacBook Air running
      OS X 10.10 (14A299l) and Xcode 6 beta 5 (6A279r).
      
      I tried filing an issue with Apple using "Feedback Assistant", but it was
      unable to send the report and lost it.
