Since initial arguments of temporary children under simple_one_for_one
supervisors are not saved, only a list of pids was stored in such
supervisors. When adding/deleting many children, this would scale
badly. To avoid this the list is now changed to a set.

* siri/stdlib/supervisor-terminate_child-simple_one_for_one/OTP-9201:
Add terminate_child(Sup, Pid) for simple_one_for_one
Allow supervisor:terminate_child(SupRef,Pid) for simple_one_for_one

supervisor:terminate_child/2 was not allowed if the supervisor used
restart strategy simple_one_for_one. This is now changed so that
children of this type of supervisors can be terminated by specifying
the child's Pid.

terminates" and improved test suite
The bug fix supplied by Filipe David Manana <[email protected]>
did not cover all possible ways that a process may be terminated
as for instance with supervisor:terminate_child. Also there
was a bug in the base case of the patch returning a list of a list instead
of only the list.
Added a timeout for the test cases, eliminated unnecessary sleeps,
improved code.

The temporary child specs are never removed from the supervisor's state, and
have they're MFA component set to {M, F, undefined} instead of the MFA passed
in the supervisor:start_child/2 call. Subsequent calls to supervisor:restart_child/2
may crash. Stack trace example:
{badarg,[{erlang,apply,[gen_server,start_link,undefined]},
{supervisor,do_start_child,2},{supervisor,handle_call,3},
{gen_server,handle_msg,5},
{proc_lib,init_p_do_apply,3}]}

* siri/stdlib/log_mf_h-write-index-atomically/OTP-9148:
Update index file atomically
|
|
Since the log_mf_h index file might be read by other processes than
the error handler (e.g. by the rb tool), this file should be updated
atomically. This will avoid hitting the time gap between opening the
file in write mode (and thus emptying the file) and the actual update
with the new contents. To do this, a temporary file is written, and
the file:rename/1 used to replace the real index file.

The default value 'undefined' was added to records field types in such
a way that the result was not always a well-formed type. This bug has
been fixed.
---
erl_pp has since OTP-8150 formatted types so that 'undefined' was
removed from union types assigned to record fields. Since one cannot
distinguish between 'undefined' added by the parser or supplied by the
user, a side effect was that user supplied 'undefined's were also
removed.
Now the pretty printer shows 'undefined' even if added by the parser.
This is a minor issue.

This new feature adds the missing week number function to the calendar module
of the stdlib application. The implementation conforms to the ISO 8601 standard.
The new feature has been implemented tested and documented.

* lukas/stdlib/native_escript/OTP-9076:
Update escrips to allow the -n or -compile(native) flag, which compiles the code within the escript with the +native flag. You need an HiPE enabled emulator for this to work.

dialyzer spec.

Previous commit changed the supervisor to not save
parameter lists for temporary processes supervised by simple-one-for-one
supervisors. But it is unnecessary to save them for any
temporary processes as they should not be restarted. Proably the
biggest gain is in the simple-one-for-one case.
Also changed the test case count_children_memory so it does
not test that which_children will produce garbage that must
be reclaimed later. This is a strange thing to test and it is no
longer true for all invocations of which_children.

Use a binary instead of a string for the help text.
|
|
Since the error messages in the erl_posix_msg module are
presumably used very seldom, save memory by using binaries
instead of strings.

* td/base64-mime-decoding:
Improve pad character handling in base64 MIME decoding functions
OTP-9020
|
|
|
|
|
|
|
|
|
|
Implement the 'MAY' clauses from RFC4648 regarding the pad character
to make mime_decode() and mime_decode_to_string() functions more
tolerant of badly padded base64. The RFC is quoted below for easy
reference.
RFC4648 Section 3.3 with reference to MIME decoding:
Furthermore, such specifications MAY ignore the pad character, "=",
treating it as non-alphabet data, if it is present before the end of
the encoded data. If more than the allowed number of pad characters
is found at the end of the string (e.g., a base 64 string terminated
with "==="), the excess pad characters MAY also be ignored.

The default maximum number of slots of Dets tables has been changed to

Remove superfluous supervisor error report
|
|
* sverker/ets_compress/OTP-8922:
ETS 'compressed' option.
|
|
The compressed format is using a slighty modified variant of the extern format
(term_to_binary). To not worsen key lookup's too much, the top tuple itself
and the key element are not compressed. Table objects with only immediate
non-key elements will therefor not gain anything (but actually consume one
extra word for "alloc_size").

|
|
* ks/file_open-mode:
Add the {encoding, _} options to file:open/2's modes
|
|
If a Dets table with fewer slots than keys was opened and then closed
after just a lookup, the contents were no longer well-formed. This bug
has been fixed. (Thanks to Matthew Evans.)
