The upgrade instruction 'remove_module' was added in OTP R7B (and
possibly in a patch in R5B or R6B, ticket OTP-3477), and translates to
the low level instruction 'remove', but adds the parameter DepMods
(modules on which Mod is dependent). The ticket says that
"remove_module should be added for symmetry with the add_module
instruction". remove_module was never documented or tested, and it was
never mentioned in a release note. It therefore seems to be low risk
in removing it.
The correct instruction to use when removing a module is
{delete_module,Mod}
which was added in OTP R10B and which is also documented and
tested. This translates to low level instructions 'remove' and 'purge'
i.e. the module is brutally purged after setting the current code to
old. This hardcoded brutal purge is the reason why PrePurge and
PostPurge parameters can not be given with the delete_module
instruction.
The parameter DepMods which was inclued in the remove_module
instruction does not exist for delete_module. From the documentation's
point of view, this is the same for add_module, and thus the two
instructions {add_module,Mod} and {delete_module,Mod} are now
symmetric. However, in the code there is a second instruction for
adding a module, {add_module,Mod,DepMods}, which is not documented. To
add symmetry even for this, {delete_module,Mod,DepMods} is now also
added. Documentation is added for all instructions.

* ia/ssl/seperate-clinet-server-session-table/OTP-11365:
ssl: Separate session cache for client and server
|
|
Even though in the most common case an erlang node will not be both client
and server, it may happen (for instance when running the erlang ditribution
over TLS).
Also try to mitigate the affect of dumb clients that could cause a
very lagre session cache on the client side that can cause long delays
in the client. The server will have other means to handle a large
session table and will not do any select operations on it anyhow.

A note in the user guide says "Only R15B nodes can be observed". This
note was written because the observer_backend module did not exist in
earlier releases. It should have said "R15B or later". However, now
that we are on OTP-17, we don't think the note is necessary anymore so
it is now removed.

* siri/cuddle-with-tests:
[ct test] Explicitly unregister event receiver to avoid badarg
|
|
If, for instance, 'warn_unused_import' is present in
ERL_COMPILER_OPTIONS then many files in Erlang/OTP (Kernel, STDLIB,
...) cannot be analyzed by Dialyzer since the option is not present
when compiling Erlang/OTP, but 'warnings_as_errors' is.
The case that ERL_COMPILER_OPTIONS contains 'warnings_as_errors' can
only be handled by ignoring ERL_COMPILER_OPTIONS.
|
|
A typical scenario: the type digraph() is used in R16 (compilation
with the option 'warnings_as_errors' results in no warning); then the
module is analyzed by a 17 Dialyzer where digraph() is obsolete, and
since the warning is turned into an error Dialyzer fails to load the
module.
Thanks to Michael Truog.

Fix edlin to correctly save text killed with ctrl-u. Prior to this fix,
entering text into the Erlang shell and then killing it with ctrl-u
followed by yanking it back with ctrl-y would result in the yanked text
being the reverse of the original killed text.
Add a test for the fix to interactive_shell_SUITE.
(This is the same fix as in PR#416, but that PR was never completed.)
