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.

A stronger version of Dialyzer complained that some case clauses in
functions xaluop_is_shift/1 and xaluop_normalise/1 are unreachable.
These clauses are now commented out. While at it, I thought that it
would be better to eliminate the catch-all clauses in order to be
certain we properly handle all RTL instructions that are used as
inputs to these functions.
Note: The code will now crash if there are unhandled cases.

"Defaults to X" isn't clarified by "if unspecified".

Since the large strings copied between processes cause testcases to fail
randomly.
Option string_decode was added in commit 1590920c.

Commit 5ca5fb71 ensured that they were closed immediately at transport
removal, but in so doing broke their closing at stop service completely,
by removing the timer that caused sockets to be closed even belatedly.
Monitor on the service process to make it happen.
This could still be improved, since stop_service listening ports aren't
closed until after the service process has died. They could be closed
earlier in the case of stop_service.

The copyright was a historical remnant of diameter's roots prior to its
inclusion in OTP.
Thanks to Anatolie Golovco.

It's '#get-'/2, not 'get-'/2. Only failed if the dictionary in question
defined no Failed-AVP, which is rarely the case in practice.
Thanks to Ferenc Holzhauser.

Register allocation could transform something like
fmove u32, d99
to
fmove $rdx, 0x20($rsp)
which is an invalid instruction.
|
|
Since the link register/return address is restored before stack
arguments are stored to the frame, we must not use it to store a stack
argument. We do that by adding it to the registers clobbered by
pseudo_tailcall_prepare.
|
|
The problem was caused by shift-by-immediate-zero, which wraps to
immediate-32 with some shiftops. TODO: Someplace should be modified to
crash when these are generated so debugging further instances of this
gets easier in the future.

The current SSL implementation has a PEM cache running through the ssl
manager process, whose primary role is caching CA chains from files on
disk. This is intended as a way to save on disk operation when the
requested certificates are often the same, and those cache values are
both time-bound and reference-counted. The code path also includes
caching the Erlang-formatted certificate as decoded by the public_key
application
The same code path is used for DER-encoded certificates, which are
passed in memory and do not require file access. These certificates are
cached, but not reference-counted and also not shared across
connections.
For heavy usage of DER-encoded certificates, the PEM cache becomes a
central bottleneck for a server, forcing the decoding of every one of
them individually through a single critical process. It is also not
clear if the cache remains useful for disk certificates in all cases.
This commit adds a configuration variable for the ssl application
(bypass_pem_cache = true | false) which allows to open files and decode
certificates in the calling connection process rather than the manager.
When this action takes place, the operations to cache and return data
are replaced to strictly return data.
To provide a transparent behaviour, the 'CacheDbRef' used to keep track
of the certificates in the cache is replaced by the certificates itself,
and all further lookup functions or folds can be done locally.
This has proven under benchmark to more than triple the performance of
the SSL application under load (once the session cache had also been
disabled).
