Compilation on Erlang 18.0-rc2 is about 10% slower than in Erlang 17.
After some debugging, we have noticed that linting is on average 30%
to 50% slower being the main responsible for the performance reduction.
Later profiling revealed is_filename/1 to be the biggest culprit. The change
in this commit brings compilation times to about the same times as Erlang 17.
Note this commit doesn't change the compiler behaviour compared to Erlang
17 because we didn't sanity check the value given to the file annotation in the
past. I would say checking the filename is not worth it if it means compilation
becomes 10% slower on average. After all, there are many places in the
compiler where it will fail if we give it a malformed tree, I wouldn't then special
case file annotation.

When compiling parser files, because they rely heavily
on inline annotations, retrieving the nowarn_bif_clash
information from the compiler options is expensive.
This patch stores nowarn_bif_clash in the lint record.
By using erlc +'{eprof,lint_module}' when compiling the
erlang parser, we noticed the time spent on
nowarn_function/2 reduced from 30% to 0.01%.

A fun could be given in the options that will be called whenever
the SSH_MSG_DEBUG message arrives. This enables the user to
format the printout or just discard it.
The default is changed to not print the message. In RFC4253
printing is a SHOULD, but our new default is to protect logs
from dos attacs.

Dialyzer warned about the incorrect match of Packets. Code
was refactored and the problem avoided in the process.
Dialyzer warned that the empty tuple is not a function as the contract
said it should be. Changed the handling of the sni_fun default value to be
undefined and added it to the contract.

The newly added function sni_fun allows dynamic update of SSL options
like keys and certificates depending on different SNI hostname, rather
than a predefined rules of SSL options.
|
|
This commit adds tests for SNI server support in:
* ssl_sni_SUITE.erl
* ssl_to_openssl_SUITE.erl
And some more modifications:
* make_certs also makes two certs for SNI, and adds
extra options for SNI.

This commit adds a new function, ssl:connection_information/[1,2]
to retrive the connection information from a SSLSocket.
And also, this deprecates a function ssl:connection_info/1, and
reimplements connection_info/1 with the new function.

The test cases

didn't work on MS Windows. This commit adds {packet,line} to get the
whole version exchange line in one packet on all architectures. It
also adds timeouts to speed up failures in those test cases.
