This document describes the changes made to the STDLIB application.

+
STDLIB 2.5 + +
Fixed Bugs and Malfunctions + + +

+ Fix handling of single dot in filename:join/2

+

+ The reference manual says that filename:join(A,B) is + equivalent to filename:join([A,B]). In some rare cases + this turns out not to be true. For example:

+

+ filename:join("/a/.","b") -> "/a/./b" vs + filename:join(["/a/.","b"]) -> "/a/b".

+

+ This has been corrected. A single dot is now only kept if + it occurs at the very beginning or the very end of the + resulting path.

+ + +

+ The undocumented option generic_debug for + gen_server has been removed.

+

+ Own Id: OTP-12183

+ + +

+ erl_lint:icrt_export/4 has been rewritten to make the + code really follow the scoping rules of Erlang, and not + just in most situations by accident.

+

+ Own Id: OTP-12186

+ + +

+ Add 'trim_all' option to binary:split/3

+

+ This option can be set to remove _ALL_ empty parts of the + result of a call to binary:split/3.

+

+ + +

Correct orddict(3) regarding evaluation order of + fold() and map().

+

+ Own Id: OTP-12651 Aux Id: seq12832

+ + +

+ Correct maps module error exceptions

+

+ Bad input to maps module function will now yield the + following exceptions: {badmap,NotMap} + or, badarg

+

+ Own Id: OTP-12657

+ + +

+ It is now possible to paste text in JCL mode (using + Ctrl-Y) that has been copied in the previous shell + session. Also a bug that caused the JCL mode to crash + when pasting text has been fixed.

+ + +
Improvements and New Features + + +

+ Allow maps for supervisor flags and child specs

+

+ Earlier, supervisor flags and child specs were given as + tuples. While this is kept for backwards compatibility, + it is now also allowed to give these parameters as maps, + see sup_flags + and child_spec.

+

+ Own Id: OTP-11043

+ + +

+ A new system message, terminate, is added. This + can be sent with sys:terminate/2,3. If the + receiving process handles system messages properly it + will terminate shortly after receiving this message.

+

+ The new function proc_lib:stop/1,3 utilizes this + new system message and monitors the receiving process in + order to facilitate a synchronous stop mechanism for + 'special processes'.

+

+ proc_lib:stop/1,3 is used by the following + functions:

+

+ gen_server:stop/1,3 (new) + gen_fsm:stop/1,3 (new) + gen_event:stop/1,3 (modified to be + synchronous) wx_object:stop/1,3 + (new)

+

+ Own Id: OTP-11173 Aux Id: seq12353

+ + +

+ Remove the pg module, which has been deprecated + through OTP-17, is now removed from the STDLIB + application. This module has been marked experimental for + more than 15 years, and has largely been superseded by + the pg2 module from the Kernel application.

+

+ Own Id: OTP-11907

+ + +

+ New BIF: erlang:get_keys/0, lists all keys + associated with the process dictionary. Note: + erlang:get_keys/0 is auto-imported.

+

+ *** POTENTIAL INCOMPATIBILITY ***

+

+ Own Id: OTP-12151 Aux Id: seq12521

+ + +

Add three new functions to io_lib-- + scan_format/2, unscan_format/1, and + build_text/1-- which expose the parsed form of the + format control sequences to make it possible to easily + modify or filter the input to io_lib:format/2. + This can e.g. be used in order to replace unbounded-size + control sequences like ~w or ~p with + corresponding depth-limited ~W and ~P + before doing the actual formatting.

+

+ Own Id: OTP-12167

+ + +

Introduce the erl_anno module, an abstraction + of the second element of tokens and tuples in the + abstract format.

+

+ Own Id: OTP-12195

+ + +

+ Support variables as Map keys in expressions and patterns

+

Erlang will accept any expression as keys in Map + expressions and it will accept literals or bound + variables as keys in Map patterns.

+

+ Own Id: OTP-12218

+ + +

The last traces of Mnemosyne Rules have been removed. +

+

+ Own Id: OTP-12257

+ + +

+ Properly support maps in match_specs

+

+ Own Id: OTP-12270

+ + +

+ New function ets:take/2. Works the same as + ets:delete/2 but also returns the deleted + object(s).

+

+ Own Id: OTP-12309

+ + +

string:tokens/2 is somewhat faster, especially + if the list of separators only contains one separator + character.

+

+ Own Id: OTP-12422 Aux Id: seq12774

+ + +

+ Prevent zip:zip_open/[12] from leaking file descriptors + if parent process dies.

+

+ Own Id: OTP-12566

+ + +

+ Add a new random number generator, see rand + module. It have better characteristics and an improved + interface.

+

+ Own Id: OTP-12586 Aux Id: OTP-12501, OTP-12502

+ + +

filename:split/1 when given an empty binary + will now return an empty list, to make it consistent with + return value when given an empty list.
