path/filepath: normalize output of EvalSymlinks on windows · c4dda7e5

Current implementation uses GetShortPathName and GetLongPathName

user can disable short path name anytime. This CL provides
an alternative approach suggested by MSDN.

cmd/compile: export inlined function bodies · a9ea36af

Robert Griesemer authored Mar 19, 2016

Completed implementation for exporting inlined functions
using the new binary export format. This change passes
(export GO_GCFLAGS=-newexport; make all.bash) but for
gc's builtin_test.go which we need to adjust before enabling
this code by default.

For a high-level description of the export format see the
comment at the top of bexport.go.

Major changes:

1) The export format for the platform independent export data
   changed: When we export inlined function bodies, additional
   objects (other functions, types, etc.) that are referred to
   by the function bodies will need to be exported. While this
   doesn't affect the platform-independent portion directly, it
   adds more objects to the exportlist while we are exporting.
   Instead of trying to sort the objects into groups, just export
   objects as they appear in the export list. This is slightly
   less compact (one extra byte per object), but it is simpler
   and much more flexible.

2) The export format contains now three sections: 1) The plat-
   form independent objects, 2) the objects pulled in for export
   via inlined function bodies, and 3) the inlined function bodies.

3) Completed the exporting and importing code for inlined function
   bodies. The format is completely compiler-specific and easily
   changeable w/o affecting other tools. There is still quite a
   bit of room for denser encoding. This can happen at any time
   in the future.

This change contains also the adjustments for go/internal/gcimporter,
necessary because of the export format change 1) mentioned above.

For #13241.

runtime: fix pagesInUse accounting · 61f56e92

Austin Clements authored Mar 29, 2016

When we grow the heap, we create a temporary "in use" span for the
memory acquired from the OS and then free that span to link it into
the heap. Hence, we (1) increase pagesInUse when we make the temporary
span so that (2) freeing the span will correctly decrease it.

However, currently step (1) increases pagesInUse by the number of
pages requested from the heap, while step (2) decreases it by the
number of pages requested from the OS (the size of the temporary
span). These aren't necessarily the same, since we round up the number
of pages we request from the OS, so steps 1 and 2 don't necessarily
cancel out like they're supposed to. Over time, this can add up and
cause pagesInUse to underflow and wrap around to 2^64. The garbage
collector computes the sweep ratio from this, so if this happens, the
sweep ratio becomes effectively infinite, causing the first allocation
on each P in a sweep cycle to sweep the entire heap. This makes
sweeping effectively STW.

Fix this by increasing pagesInUse in step 1 by the number of pages
requested from the OS, so that the two steps correctly cancel out. We
add a test that checks that the running total matches the actual state
of the heap.

Fixes #15022. For 1.6.x.

syscall: add support for s390x · af74dca4

Michael Munday authored Mar 31, 2016

On s390x char is unsigned. We cannot force it to be signed using
-fsigned-char (see arm64) because the s390x gccgo API is already
public and we need to stick as closely as possible to it to avoid
breaking existing projects. In order to match the gccgo API we
also force the RawSockaddr.Data and RawSockaddrUnix.Path fields
to be signed.

This CL adds a post-processing pass (mkpost.go) to mkall.sh in
order to export the types of fields in PtraceRegs on s390x
without affecting the API on other platforms. The types of these
fields match their counterparts in gccgo. mkpost.go also cleans
up the Pad_cgo* fields and X_* fields (these fields are not
exported by gccgo currently). It could be extended to add build
tags on platforms that need them.

path, path/filepath: add Join example with joined rooted path · 1f7e55e4

Russ Cox authored Mar 15, 2016

This makes clear that Go's path.Join and filepath.Join are different
from the Python os.path.join (and perhaps others).

Requested in private mail.

fmt: hold on to all free buffers, regardless of size · 0656da91

Brad Fitzpatrick authored Apr 03, 2016

This code made sense before fmt switched to using sync.Pool, but a
sync.Pool clears all items on GC, so not reusing something based on
size is just a waste of memory.

compress/gzip: fix Reader.Reset · 4ae4e81c

Joe Tsai authored Apr 02, 2016

Rather than specifying every field that should be cleared in Reset,
it is better to just zero the entire struct and only preserve or set the
fields that we actually care about. This ensures that the Header field
is reset for the next use.

compress/gzip: cleanup gzip package · 0d40dfa7

Joe Tsai authored Apr 02, 2016

Changes made:
* Reader.flg is not used anywhere else other than readHeader and
does not need to be stored.
* Store Reader.digest and Writer.digest as uint32s rather than as
a hash.Hash32 and use the crc32.Update function instead. This simplifies
initialization logic since the zero value of uint32 is the initial
CRC-32 value. There are no performance detriments to doing this since
the hash.Hash32 returned by crc32 simply calls crc32.Update as well.
* s/[0:/[:/            Consistently use shorter notation for slicing.
* s/RFC1952/RFC 1952/  Consistently use RFC notation.

cmd/compile: eliminate dead code in walkappend · 75a22d0d

Matthew Dempsky authored Apr 01, 2016

The IsStruct case is meant to handle cases like append(f()) where f's
result parameters are something like ([]int, int, int). However, at
this point in the compiler we've already rewritten append(f()) into
"tmp1, tmp2, tmp3 := f(); append(tmp1, tmp2, tmp3)".

As further evidence, the t.Elem() is not a valid method call for a
struct type anyway, which would trigger the Fatalf call in Type.Elem
if this code was ever hit.

runtime, syscall: only search for Windows DLLs in the System32 directory · 683448a3

Brad Fitzpatrick authored Mar 25, 2016

Make sure that for any DLL that Go uses itself, we only look for the
DLL in the Windows System32 directory, guarding against DLL preloading
attacks.

(Unless the Windows version is ancient and LoadLibraryEx is
unavailable, in which case the user probably has bigger security
problems anyway.)

This does not change the behavior of syscall.LoadLibrary or NewLazyDLL
if the DLL name is something unused by Go itself.

This change also intentionally does not add any new API surface. Instead,
x/sys is updated with a LoadLibraryEx function and LazyDLL.Flags in:
    https://golang.org/cl/21388
