* josevalim/atu8-chunk/PR-1078/OTP-14178:
Add new AtU8 beam chunk
|
|
The new chunk stores atoms encoded in UTF-8.
beam_lib has also been modified to handle the new
'utf8_atoms' attribute while the 'atoms' attribute
may be a missing chunk from now on.
The binary_to_atom/2 BIF can now encode any utf8
binary with up to 255 characters.
The list_to_atom/1 BIF can now accept codepoints
higher than 255 with up to 255 characters (thanks
to Björn Gustavsson).

The BIF process_info(Pid, current_stacktrace) truncates the
stacktrace. The old behavior was to truncate long stacktraces to max
8 items. And this was hard coded. Now it is truncated to the value of
system_flag(backtrace_depth) instead. The backtrace_depth defaults to
8, but is configurable.

erts: Fix some system_info docs inconsistencies
Add system_info(atom_limit)
|
|
|
|
Add system_info(atom_limit) to provide a way to retrieve the maximum
number of atoms allowed. Add tests and documentation for it too.
Also split system_info_SUITE:start_node/2 to start_node_ets/2 and
start_node_atm/2 to avoid code duplication.

and instead let erlang:load_nif/2 return {error, {reload, _}}
before even trying to load the library
if a NIF library has already been successfully loaded
for the calling module instance.

Implement as ceil/1 and floor/1 as new guard BIFs (essentially part of
Erlang language). They are guard BIFs because trunc/1 is a guard
BIF. It would be strange to have trunc/1 as a part of the language, but
not ceil/1 and floor/1.
|
|
Fix some older errors as well.

Ensure that we cannot get any dangling pointers into code that
has been purged. This is done by a two phase purge. At first
phase all fun entries pointing into the code to purge are marked
for purge. All processes trying to call these funs will be suspended
and by this we avoid getting new direct references into the code.
When all processes has been checked, these processes are resumed.
The new purge strategy now also completely ignore the existence of
indirect references to the code (funs). If such exist, they will
cause bad fun exceptions to the caller, but will not prevent a
soft purge or cause a kill of a process having such live references
during a hard purge. This since it is impossible to give any
guarantees that no processes in the system have such indirect
references. Even when the system is completely clean from such
references, new ones can appear via distribution and/or disk.

Besides using two words for 'milliseconds' et. al. they are
also changed from plural to singular.

Note: Minor GC option is a hint, and GC may still decide to run fullsweep.

This commit only changes the order of functions and does some
other rearrangements to that the diff with the next commit will
be easier to follow. No content or XML tags are changed.
