The core issues this patch attempts to solve is two fold, 1) have
release_handler_1 act slightly differently in two corner cases and 2)
clean up the code in get_supervised_procs/0 to remove nested cases and
etc.
Regarding #1, get_supervised_procs/0 will now call functions to
test to see if the supervisor is suspended before attempting to ask it
for a list of children. It now will print an error message regarding
the suspended supervisor and produce an error that will cause the VM
to restart. Previously it would timeout attempting the call to
which_children and the VM would restart without any details regarding
the reason.
The second corner case is if in a child specification a supervisor is
incorrectly stated to be a worker and get_modules is called against it.
A timeout will occur causing a VM restart. Similar to the last corner
case in this patch an error message is printed and an error is emitted
causing a VM restart.
When first looking into the issue it was hard to discover why my
upgrades where failing. All I received during the upgrade process was
a timeout and a VM restart, no other information. This patch should
help users track down issues like these.
Regarding #2, due to the above confusion in trying to figure out what
had happened I dug into the code and started tracing it through and
found that the nested case statements and etc made it confusing. So I
started to rework and clean up, hopefully making this code path clearer
to future readers.

* sa/prim-file-fix:
Update preloaded module
Replace atom in DRV macro in prim_file with string
|
|
|
|
An experimental version of Dialyzer discovered that the atom that
replaced the DRV macro in prim_file ends up in calls to
erlang:open_port({spawn, Driver}, Portopts) as the Driver argument. The
documentation states that this call requires a string there.
This change is also consistent with the one introduced in commit
0f03b1e9d2bef3bc830c31a369261af4c5234727 by Kostis Sagonas.

* ia/odbc/test-improvment:
Modernized the test suites
|
|
In ssl-4.1.5 temporary clean-up processes would crash resulting in
that the session table would not be cleaned up (e.i. using more and
more memory) and error reports would be printed, but connections would
not be affected.

to the test suites.

Two opaque types that could cause warnings when running Dialyzer have
been modified.

* hb/stdlib/spec_fix/OTP-9333:
Fix a spec and a type
|
|
Warnings about wrong contract ranges are post-processed to be displayed in the
file/line that contains the contract, although they can also be emitted while
processing other modules. For this relocation to succeed the module that
contains the contract should be currently under analysis. If this is not the
case the warning is displayed in the file/line of the call that proves the
discrepancy in the contract.
|
|
While at it:
1. Moved types in their proper place
2. Did minor cleanups and
3. Took out an unused function
|
|
A specification that could cause problems for Dialyzer has been fixed.
An opaque type in erl_eval has been turned in to a ordinary type. This
is a temporary fix.
