ssh: Fix bug causing rekeying once per minute after 1st Gbyte Thanks Simon
|
|
The port stats are not accumulated so that once rekey_limit bytes
(by default, 1GB) have been transmitted the connection will be
rekeyed every minute, not after the next 1GB.

As the erl_anno module is used by the compiler, it must be included
in the set of modules that are used when building the primary
bootstrap.

As long as the Erlang Compiler and qlc do not agree on the location of
LC warnings, qlc's own warnings about patterns and filters that always
fail have been silenced.

Introduce erl_anno, an abstraction of the second element of tokens and
tuples in the abstract format. The convention that negative line
numbers can be used for silencing compiler warnings will no longer
work in OTP 19; instead the annotation 'generated' is to be used.

Simplify the uniq/0 function by using erlang:unique_integer/1.
|
|
The intention of the comparison is to avoid unnecessary updates of the
">=" instead of ">". With the ">" comparison, typically every line
instruction would cause the #asm{} record to be updated.
|
|
In 8470558, the drop_labels/1 function was added to beam_utils
as a minor optimization. Since the function is already available,
we might as well use it in index_label/3 too.
|
|
The misc_SUITE:integer_encoding/1 test case is annoyingly slow.
Rewrite the encoding of integers in beam_asm to use the
binary:encode_unsigned/1 BIF.
Also tweak the test case itself. Scale the down the maximum
size of the numbers being generated, but also add test of
numbers around boundaries of power of two (which are the numbers
most likely to expose bugs in the encoding).
|
|
It is not necessary to compile the compile three times. After the
second compilation, we compare the generated .beam files with the
.beam files that were used when compiling them. Doing one more
round will not find more bugs.
While we are it, remove the ?line macros and the unused make_current/1
function.
|
|
The test suites generates listing files, so we can slightly speed
up running of test suites (especially when running 'cover') by
optimizing writing of .S files.
|
|
|
|
Using 'try'...'catch' simplifies the code and improves coverage
because we don't have to re-throw accidentally caught errors.
|
|
86fbd6d76d strengthened type optimization in lets. As a result of
the stronger optimizations, special care had to be taken to
suppress false warnings.
It turns out that false warnings can still slip through. Slapping
on a 'compiler_generated' annotation at the top-level of a
complex term such as #c_tuple{} may not suppress all warnings.
We will need to go deeper into the term to eliminate all warnings.
|
|
Understanding get_map_elements improves the stack trimming done
by beam_trim.
|
|
|
|
beam_utils used to be overly conservative about liveness for
exit instructions such as:
call_ext erlang:exit/1
beam_utils would consider all y registers to be used, to avoid
overwriting a catch or try tag. That does not seem to be a real
risk.
However, we miss opportunities for stack trimming if we consider
y registers used by an exit instruction.
