When both options 'warnings_as_errors' and 'silent' were given to
systools:make_script or systools:make_relup, no error reason would be
returned if warnings occured. Instead only the atom 'error' was
returned. This is now corrected.
Options 'warnings_as_errors' and 'no_warn_sasl' are now also allowed
for systools:make_tar.

Add the possibility to use modules as trace data receivers. The functions
in the module have to be nifs as otherwise complex trace probes will be
very hard to handle (complex means trace probes for ports for example).
This commit changes the way that the ptab->tracer field works from always
being an immediate, to now be NIL if no tracer is present or else be
the tuple {TracerModule, TracerState} where TracerModule is an atom that
is later used to lookup the appropriate tracer callbacks to call and
TracerState is just passed to the tracer callback. The default process and
port tracers have been rewritten to use the new API.
This commit also changes the order which trace messages are delivered to the
potential tracer process. Any enif_send done in a tracer module may be delayed
indefinitely because of lock order issues. If a message is delayed any other
trace message send from that process is also delayed so that order is preserved
for each traced entity. This means that for some trace events (i.e. send/receive)
the events may come in an unintuitive order (receive before send) to the
trace receiver. Timestamps are taken when the trace message is generated so
trace messages from differented processes may arrive with the timestamp
out of order.
Both the erlang:trace and seq_trace:set_system_tracer accept the new tracer
module tracers and also the backwards compatible arguments.

Add commonly used modules to the list of modules in
mandatory_modules/0. Having those modules listed will potentially
help the 'init' module to load them in parallel during start-up.

The reason is that the module is not used, and that we se no obvious

This function is used by release_handler during upgrade. This was
earlier implemented in the release_handler, but it required a copy og
the definition of the supervisor's internal state, which caused
problems when this state was updated.
|
|
When release_handler_1:get_supervised_procs/0 does a recursive walk of
the supervision tree, it calls sys:get_status/1 on supervisors, to check
if they are suspended or running.
This fixes a race condition where a list of supervisor pids is gathered,
one of them (legitimately) exits before release_handler can examine it,
then sys:get_status/1 is called with a dead pid, causing an exit(noproc)
See: http://erlang.org/pipermail/erlang-questions/2015-August/085712.html
(To recreate this problem for testing, I added a timer:sleep into the
release_handler_1 code, and killed a supervisor during
get_supervised_procs being called).

The module is deprected and will be removed in OTP 19. The reason is
that the module is not used, and that we se no obvious use case for

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"}]}.

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

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.
