`timezone` variable contains the difference, in seconds, between UTC and
local standard time (see `man 3 localtime` on Solaris).
Call to `tzset` is required to apply contents of `TZ` variable to
`timezone` variable.

Patch from Maciej Małecki <me@mmalecki.com>.
This is a back-port of upstream commit r12802 and a forward port of
commit 9fa953d from the v0.8 branch. V8 3.22 in the master branch
contains the patch so no further forward-porting is necessary.
This commit removes the simple/test-event-emitter-memory-leak test for
being unreliable with the new garbage collector: the memory pressure
exerted by the test case is too low for the garbage collector to kick
in. It can be made to work again by limiting the heap size with the
--max_old_space_size=x flag but that won't be very reliable across
platforms and architectures.
The security fix from commit 6b92a713 also back-ported the test case.
Said test case relies on API that is only available in newer versions
of V8 and, as a result, broke the `make native` and `make <arch.mode>`
builds. This commit reverts that part of the back-port. Fixes the
following build error:
../test/cctest/test-api.cc: In function ‘void TestRegress260106()’:
../test/cctest/test-api.cc:17712:34: error: ‘class v8::Context’ has
no member named ‘GetIsolate’
Profiling suggested that on Linux sometimes over 10% of CPU time was
being spent inside the systemtap probe entry points in the binding
layer, even when the process was not actively being traced with the
`stap` tool.
That's why this commit makes it possible to use the *_ENABLED() macros
and bail out early when we're not being traced, reducing the overhead
of unused probes to (almost) zero.
Said macros were already being generated by `dtrace -h` but were not
usable because they rely on external definitions. To remedy that, we
now generate the accompanying object files with `dtrace -G`.
This commit includes a change to libuv that has been landed upstream in
commit joyent/libuv@3c172ea.
This change makes several improvements to the ustack helper and MDB
support:
- ustack helper and MDB: add support for two-byte strings
(necessary to print many filenames in stacktraces in 0.10 and later).
- ustack helper: fix position numbers, which were off by a factor of two
- ustack helper: fix frames with undefined Scripts (e.g., "RegExp")
- ustack helper: add stub frames
- MDB: add support for sliced strings
- MDB: sync up with changes from the illumos version of the module
Fixes#6309Closes#6318
After the upgrade from 3.20.17.7 to 3.20.17.11, we've begun hitting
random assertions in V8 in memory-constrained / GC-heavy situations.
The assertions all seem to be related to heap allocations and garbage
collection but apart from that, they're all over the place.
This reverts commit 970bdccc38.
This commit changes src/tcp_wrap.cc and src/udp_wrap.cc just enough to
get by (i.e. to compile and function correctly.)
The new libuv API allows for more cleanup and deduplication but I'm
saving that for another day.
This is [1] applied ahead of time. Summary:
OpenBSD doesn't have <ucontext.h>. ucontext_t lives in <signal.h>
and is a typedef for struct sigcontext. There is no uc_mcontext.

Note: the patch has been accepted upstream but hasn't made its way into
a stable release yet.
Quoting the CVE:
Google V8, as used in Google Chrome before 28.0.1500.95, allows
remote attackers to cause a denial of service or possibly have
unspecified other impact via vectors that leverage "type confusion."
Likely has zero impact on node.js because it only runs local, trusted
code but let's apply it anyway.
This is a back-port of upstream commit r15665. Original commit log:
Use internal array as API function cache.
