'parent' is route node and 'neighbor' is base node,
they can never be equal.
'neighbor_parent' has already been set correctly for all cases.
|
|
Search stack must be cleared before retry.

|
|
Lock order is reverse tree depth, from leafs toward root.
This solution may eventually fail if running too long
as route nodes do not increase their 'lc_order' in a join operation
when they move up in the tree.
But who runs a VM with lock-checker for such a long time?
|
|
Lock order is key term order, so each base node needs its own key
if lock check is enabled.

Fewer variables with shorter names
and prefer DbTableCATree over DbTableCommon.
|
|
Update table memory stats before scheduling free
to not be dependent on deallocation order with main table struct.

Introduce the no_spawn_compiler_process option

If a fun is defined locally and only used for calls, it can be replaced
with direct calls to the relevant function. This greatly speeds up "named
functions" (which rely on make_fun to recreate themselves) and macros that
wrap their body in a fun.

'Content-Type' is sent when it is explicitly set as a header or
there is a non-empty body in the request.
Former implementation dropped the explicit 'Content-Type' when
the request had an empty body.

Also implement the same option for the legacy undocumented functions
inet:getif/1,getiflist/1,ifget/2,ifset/2.
The arity 1 functions had before this change got signatures that
took a socket port that was used to do the needed syscall, so now
the signature was extended to also take an option list with the
only supported option {netns,Namespace}. The Socket argument
variant remains unsupported.
For inet:getifaddrs/1 the documentation file was changed to old
style function name definition so be able to hide the Socket
argument variant that is visible in the type spec.
The arity 2 functions had got an option list as second argument.
This list had to be partitioned into one list for the namespace
option(s) and the other for the rest.
The namespace option list was then fed to the already existing
namespace support for socket opening, which places the socket
in a namespace and hence made all these functions that in
inet_drv.c used getsockopt() work without change.
The functions that used getifaddrs() in inet_drv.c had to be
changed in inet_drv.c to swap namespaces around the
getifaddrs() syscall. This functionality was separated into
a new function call_getifaddrs().

We forgot to do this in the BSM optimization branch, and this is
as good a time as any to get it fixed.

By default, all code is compiled in a separate process
which is terminated at the end of compilation. However,
some tools, like Dialyzer or compilers for other BEAM languages,
may already manage their own worker processes and spawning
an extra process may slow the compilation down.
In such scenarios, you can pass this option to stop the
compiler from spawning an additional process.
This generalizes commit 657760e18087b0cdbaecc5e96e46f6f66bc9497a.

OTP 22 extends the binary instructions to support a Y register
destination. When giving an option to compile for an earlier
release, make sure that binary instructions don't use a Y register
destination, by rewriting the binary instructions to use an X
register destination and adding a `move` instruction to move
the value to the Y register.

Rewrite BSM optimizations in the new SSA-based intermediate format
|
|
|
|
This has been superseded by bs_get_tail/3. Note that it is NOT
removed from the emulator or beam_disasm, as old modules are still
legal.
|
|
Remove the variable aliasing support that was needed for the
old beam_bsm pass.
|
|
|
|
The beam_ssa_bsm pass welds chained matches together, but the match
expressions themselves are unchanged and if there's a tail
alignment check it will be done each time. This subpass figures out
the checks we've already done and deletes the redundant ones.
|
|
This commit improves the bit-syntax match optimization pass,
leveraging the new SSA intermediate format to perform much more
aggressive optimizations. Some highlights:
* Watch contexts can be reused even after being passed to a
function or being used in a try block.
* Sub-binaries are no longer eagerly extracted, making it far
easier to keep "happy paths" free from binary creation.
* Trivial wrapper functions no longer disable context reuse.

2e40d8d1c51a attempted fix a bug in binary matching, but it only
fixed the bug for the minimized test case.
This commit removes the previous fix and fixes the bug in a more
effective way. See the comments in the new code in `sys_core_bsm`
for an explanation.
This commit restores the optimizations in string.erl and dets_v9.erl
that the previous fix disabled.
I have not found any code where this commit will disable optimizations
when they are actually safe. There are some changes to the code
in ssl_cipher.erl in that some bs_start_match2 instruction did not
reuse the binary register for the match context, but the delayed
sub binary optimizations was never applied to the code in the first
place.

As TLS 1.3 introduces more extensions in other places than in hello messages
we like to have generalize extension handling encode/decode with some
hello wrappers.
Also extend property tests of handshake encod/decode
|
|
|
|
Moving away this optimization makes beam_block do one thing
and one thing only -- creating blocks.
