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.

* dumbbell/function_clause-in-systools_make-format_error:
sasl: Fix crash in systools_make:format_error/1
OTP-11819
|
|
The crash occurred when systools:make_script/2 raises the
'duplicate_modules' error. Depending on the 'silent' option,
systools_make:format_error/1 is called to either format and display an
error message, or return a tuple containing the error properties.
When displaying a 'duplicate_modules' error message, format_error/1
receives a list of applications providing the same module(s):
[
{{Mod,App1,_}, {Mod,App2,_}},
...
]
However, before this fix, format_error/1 expected the following
structure, leading to a 'function_clause' exception:
[
{{Mod,_,App1,_,_}, {Mod,_,App2,_,_}},
...
]
The crash never occurred with the 'silent' option, because the error and
its properties are returned as is to the caller.

Most dependencies introduced are exactly the dependencies to other
applications found by xref. That is, there might be real dependencies
missing. There might also be pure debug dependencies listed that
probably should be removed. Each application has to be manually
inspected in order to ensure that all real dependencies are listed.
All dependencies introduced are to application versions used in
OTP 17.0. This since the previously used version scheme wasn't
designed for this, and in order to minimize the work of introducing
the dependencies.

* siri/restart_app-type/OTP-11716:
[sasl] Use restart type from .rel when restarting apps during upgrade
|
|
Earlier the 'restart_application' upgrade instruction always cause the
application to be restarted as permanent. This could cause the system
to end up in an unexpected state after an upgrade. This is now
corrected.
|
|
Appups now only support one major release back, and the tests are
updated accordingly.
Support is also added in tests for giving previous releases in a ct
config file, e.g.
{otp_releases,[{r15,"/path/to/r15/bin/erl"},
{r16,"/path/to/r16/bin/erl"},
{'17',"/path/to/17/bin/erl"}]}.

A previous refactoring messed up the paths used in the start.boot
file used in intermediate releases generated for emulator upgrades.

The functions add_error_logger_mf/1 and delete_error_logger_mf/1 in sasl.erl
are designed to do nothing if the handler configuration as returned by
get_error_logger_mf/0 is 'undefined'. However, that function returns a
triple {undefined,undefined,undefined} when the error_logger_mf_*
configurations have not been set. This makes SASL always try to add the
log_mf_h handler on startup, passing 'undefined' for each of the Dir, MaxB
and MaxF parameters. The gen_event callback function log_mf_h:init/1 will
then crash with a function_clause error, causing the handler to be silently
removed again. This patch fixes the problem by making get_error_logger_mf/0
return the single atom 'undefined' as it is expected to do.

Sometimes it is wanted to start erlang without loading the user dependent
.erlang file, for example in scripts and configure tests.

rb was only accepting physical filenames as log file.
This patch allow rb to accept now any io_device, valid registered name,
except standard_error which is replaced by standard_io.
Creation of two new exported functions : rb:log_list/0-1
that print in log file if existing, otherwise on standard_io.
Add new functions documentation and tests in rb_SUITE.

Using the low-level BEAM instructions, we can loop over each message in
the process queue and removes the first message that matches, without
receiving them all to later send them back to itself.
The function prim_eval:'receive'/2 is equivalent to the
following pseudo-code:
'receive'(F, T) ->
RESET MESSAGE QUEUE POINTER,
LOOP:
case PEEK CURRENT MESSAGE WITH TIMEOUT T of
{ok,Msg} ->
case F(Msg) of
nomatch ->
DECREMENT TIMEOUT T,
ADVANCE MESSAGE QUEUE POINTER,
GOTO LOOP;
Result ->
RESET MESSAGE QUEUE POINTER,
Result
end;
timeout ->
RESET MESSAGE QUEUE POINTER,
timeout
end.
To not break Dialyzer and other tools, we use a stub Erlang module which
abstract code is forcefully inserted into prim_inet.erl afterwards
compilation.

Also clean up appup_test in sasl_SUITE by removing old versions that
are no longer used.

This is to allow space in the path.

* nox/enable-silent-rules/OTP-10726:
Implement ./otp_build configure --enable-silent-rules

With silent rules, the output of make is less verbose and compilation
warnings are easier to spot. Silent rules are disabled by default and
can be disabled or enabled at will by make V=0 and make V=1.

It was possible to insert {Mod::atom(),Vsn::term()} instead of
Mod::atom() in the modules list in a .app file. This was not visible
in the documentation of .app files, but it was visible in the
documentation of application:load/[1,2] (where the .app file term can
be used directly as first argument).
The Vsn part was never used, so this possibility has now been removed.
