      undo CL 101570044 / 2c57aaea79c4 · f378f300
      Keith Randall authored
      redo stack allocation.  This is mostly the same as
      the original CL with a few bug fixes.
      
      1. add racemalloc() for stack allocations
      2. fix poolalloc/poolfree to terminate free lists correctly.
      3. adjust span ref count correctly.
      4. don't use cache for sizes >= StackCacheSize.
      
      Should fix bugs and memory leaks in original changelist.

      runtime: stack allocator, separate from mallocgc
      
      In order to move malloc to Go, we need to have a
      separate stack allocator.  If we run out of stack
      during malloc, malloc will not be available
      to allocate a new stack.
      
      Stacks are the last remaining FlagNoGC objects in the
      GC heap.  Once they are out, we can get rid of the
      distinction between the allocated/blockboundary bits.
      (This will be in a separate change.)

      1. Add select on sync channels benchmark.
      2. Make channels in BenchmarkSelectNonblock shared.
      With GOMAXPROCS=1 it is the same, but with GOMAXPROCS>1
      it becomes a more interesting benchmark.

      strings: remove byteBitmap · 90870e61
      Rui Ueyama authored
      Previously we had a bitmap to check whether or not a byte
      appears in a string should be replaced. But we don't actually
      need a separate bitmap for that purpose. Removing the bitmap
      makes the code simpler.

      archive/tar: fix writing of pax headers · 7a9e7c0a
      Cristian Staretu authored
      "archive/tar: reuse temporary buffer in writeHeader" introduced a
      change which was supposed to help lower the number of allocations from
      512 bytes for every call to writeHeader. This change broke the writing
      of PAX headers.
      
      writeHeader calls writePAXHeader and writePAXHeader calls writeHeader
      again. writeHeader will end up writing the PAX header twice.
      
      example broken header:
      PaxHeaders.4007/NetLock_Arany_=Class_Gold=_Ftanstvny.crt0000000000000000000000000000007112301216634021512 xustar0000000000000000
      PaxHeaders.4007/NetLock_Arany_=Class_Gold=_Ftanstvny.crt0000000000000000000000000000007112301216634021512 xustar0000000000000000
      
      example correct header:
      PaxHeaders.4290/NetLock_Arany_=Class_Gold=_Ftanstvny.crt0000000000000000000000000000007112301216634021516 xustar0000000000000000
      0100644000000000000000000000270412301216634007250 0ustar0000000000000000
      
      This commit adds a dedicated buffer for pax headers to the Writer
      struct. This change increases the size of the struct by 512 bytes, but
      allows tar/writer to avoid allocating 512 bytes for all written
      headers and it avoids allocating 512 more bytes for pax headers.
