Historically, for no good reason, a function is allowed to have
from 0 to 256 arguments. Thus, the number of arguments *almost*
fits into a byte.
HiPE only supports up to 255 arguments (because it assumes that
the function arity fits into a single byte), and fixing that limitation
would require ugly special-case handling. In Dialyzer, the arity
type is defined to be a byte (i.e. 0..255).
Since no-one uses functions with 256 arguments anyway, lower the
limit to 255.

* bjorn/remove-books:
Documentation: Remove the system/doc/Books directory
|
|
The latest additions to the extension of Erlang used for describing
types and specifications have been documented. There are new compiler
attributes such as -opaque and -export_all as well as an alternative
syntax for subtype constraints ('::' instead of is_subtype/2).
|
|
Building of books is probably severerly broken by now,
and there are no plans to print any more books, so there
is no reason to keep the directory.

Wrote and changed some tests in stdlib:erl_lint_SUITE
nowarn_bif_clash is obsoleted but will remove warnings and errors about bif
clashes. The recommended way is to use no_auto_import directives instead.
Hopefully erlang.erl is the only user in the world of nowarn_bif_clash.

* ta/nested-records:
Document R14 paren-less record access/update
Support nested record field access without parentheses
OTP-8597 ta/nested-records
Nested records can now be accessed without parenthesis. See the Reference
Manual for examples. (Thanks to YAMASHINA Hio and Tuncer Ayaz.)

Add a section to the reference manual describing the R14
change to not require parentheses when accessing or updating
fields in nested records.

is_boolean/1 was introduced in R10B, so this is a little

The most important "readme" files now use Markdown notation. HTML
versions of these files are now also automatically generated and
included in the HTML documentation.
- Building and Installing Erlang/OTP - $ERL_TOP/INSTALL.md
(previously known as $ERL_TOP/README).
- Cross Compiling Erlang/OTP - $ERL_TOP/INSTALL-CROSS.md.
- How to Build Erlang/OTP on Windows - $ERL_TOP/INSTALL-WIN32.md
(previously known as $ERL_TOP/README.win32).

environment after a number of bugs are fixed and some features
are added in the documentation build process.
- The arity calculation is updated.
- The module prefix used in the function names for bif's are
removed in the generated links so the links will look like
"http://www.erlang.org/doc/man/erlang.html#append_element-2"
instead of
"http://www.erlang.org/doc/man/erlang.html#erlang:append_element-
2".
- Enhanced the menu positioning in the html documentation when a
new page is loaded.
- A number of corrections in the generation of man pages (thanks
to Sergei Golovan)
- The legal notice is taken from the xml book file so OTP's build
process can be used for non OTP applications.

An on_load function is supposed to return 'true' to indicate
that the module should be loaded, and 'false' if it should be
unloaded. But returning any other term, as well as causing an
exception, will also unload the module.
Since we don't like boolean values mixed with other values,
change the expected return value as follows:
* If 'ok' is returned, the module will remain loaded and become
callable.
* If any other value is returned (or an exception is generated),
the module will be unloaded. Also, if the returned value is
not an atom, send a warning message to the error_logger
(using error_logger:warning_msg/2).
The new interpretation of the return value means that an on_load
function can now directly return the return value from
erlang:load_nif/2.
|
|
NIF function prototypes in order to allow more than 3 function
arguments. Also an incompatible change in the return value of
erlang:load_nif/2. Added support for references, floats and term
comparison in NIFs. Read more in the documentation of erl_nif and
erlang:load_nif/2.
|
|
In the transition from SGML to XML (several releases ago),
bugs were introduced in the documentation, for instance
"\n" replaced by newlines. Correct those bugs.
Also correct double backslashes. They seem to have been introduced very
early in the development of OTP. According to Lars they "solved" a bug
in the generation of HTML &c. Now that standard tools are used instead
of docbuilder, the bug has become visible.
