* egil/egd_render:
Fix egd_render transparent to use float constants
OTP-8425 Fix egd_render transparent to use float constants.
The render engine has float guards to enhance beam code
generation. However, the default case used integers which caused
the engine to crash. This is now fixed.

* rani/inet_gethostbyname_fixes:
inet_res_SUITE: testcase fixes for legacy DNS resolver (Solaris 8)
inet_res: /etc/resolv.conf: use domain as default search list
inet: delayed/avoided read of /etc/resolv.conf and /etc/hosts
inet_gethost_native: workaround for empty result hostname on MacOS X
inet_res_SUITE: testcase fix for empty domain name
inet:gethostbyname improved to parse IP strings and look up own hostname
OTP-8426 The resolver routines failed to look up the own node name as
hostname, if the OS native resolver was erroneously configured,
bug reported by Yogish Baliga, now fixed.
The resolver routines now tries to parse the hostname as an IP
string as most OS resolvers do, unless the native resolver is
used.
The DNS resolver inet_res and file resolver inet_hosts now do not
read OS configuration files until they are needed. Since the
native resolver is default, in most cases they are never needed.
The DNS resolver's automatic updating of OS configuration file
data (/etc/resolv.conf) now uses the 'domain' keyword as default
search domain if there is no 'search' keyword.
|
|
|
|
|
|
When the search list option in /etc/resolv.conf was empty, the
domain option was not used as default search domain.
That has been fixed in this patch.
|
|
The 'file' and 'dns' lookup methods configuration files
are now read and parsed at the time of the first lookup
instead of at boot time when per default none of these
lookup methods are used.
|
|
On MacOS X the getaddrinfo function apparently can return a result
without canonical hostname e.g when looking up a IPv6 address
string as hostname. The receiving erlang code was not prepared
for that and this patch does a workaround by using the
search string as default value for canonical hostname.
|
|
|
|
Now inet:gethostbyname tries to parse the hostname as an IP string
first if the 'native' lookup method is not used. One can also
make the IP string parsing explicit using the new 'string'
lookup method, or avoid it using the new pseudo lookup
method 'nostring'.
In R13B04 a bug was introduced when the gethostbyname code
was rewritten, so if the native resolver was used and
misconfigured to not be able to look up the own hostname,
inet:gethostbyname also failed. This is now fixed.

This avoids costly scheduling changes during module loading if native
code is disabled in erts, or not present in the module being loaded.

* sc/sctp-connect-nowait:
Implement a non-blocking SCTP connect
OTP-8414 There are new gen_sctp:connect_init/* functions that initiate an
SCTP connection without blocking for the result. The result is

Tuncer Ayaz.)
|

This patch adds a new set of functions - gen_sctp:connect_init/* that initiate
an SCTP connection without blocking for the result. The result is delivered
asynchronously as an sctp_assoc_change event.
The new functions have the same API as documented for gen_sctp:connect/* with
the following exceptions:
* Timeout is only used to supervise resolving Addr (the peer address)
* The possible return values are ok | {error, posix()}
The caller application is responsible for receiving the #sctp_assoc_change{}
event and correctly determining the connect it originated from (for example,
by examining the remote host and/or port). The application should have at
least {active, once} or use gen_sctp:recv to retrieve the connect result.
The implementation of gen_sctp:connect suffers from a number of
shortcomings which the user may avoid by using gen_sctp:connect_init and
adding code to receive the connect result.
First, irrespective of the Timeout value given to gen_sctp:connect, the OS
attempts and retries the SCTP INIT according to various kernel parameters. If
the Timeout value is shorter than the entire attempt then the application will
still receive an sctp_assoc_change event after the {error, timeout} is
returned from the initial call. This could be somewhat confusing (either to
the application or the designer!) especially if the status is
comm_up. Subsequent calls to connect before the OS has finished this process
return {error, ealready} which may also be counter-intuitive.
Second, there is a race-condition (documented in comments in inet_sctp.erl)
that can cause the wrong sctp_assoc_change record to be returned to an
application calling gen_sctp:connect. The race seriously affects connection
attempts when using one-to-many sockets.

code:clash/0 did not take into account .ez files

Using erl_prim_loader:list_dir/1 instead of
file:list_dir/1 fixes the problem.

improvements.
Most notable:
Lots of cross compilation improvements. The old cross compilation
support was more or less non-existing as well as broken. Please,
note that the cross compilation support should still be
considered as experimental. Also note that old cross compilation
configurations cannot be used without modifications. For more
information on cross compiling Erlang/OTP see the
$ERL_TOP/xcomp/README file.
Support for staged install using <url
href="http://www.gnu.org/prep/standards/html_node/DESTDIR.html">D
ESTDIR</url>. The old broken INSTALL_PREFIX has also been fixed.
For more information see the $ERL_TOP/README file.
Documentation of the release target of the top Makefile. For more
information see the $ERL_TOP/README file.
make install now by default creates relative symbolic links
instead of absolute ones. For more information see the
$ERL_TOP/README file.
$ERL_TOP/configure --help=recursive now works and prints help for
all applications with configure scripts.
Doing make install, or make release directly after make all no
longer triggers miscellaneous rebuilds.
Existing bootstrap system is now used when doing make install, or
make release without a preceding make all.
The crypto and ssl applications use the same runtime library path
when dynamically linking against libssl.so and libcrypto.so. The
runtime library search path has also been extended.
The configure scripts of erl_interface and odbc now search for
thread libraries and thread library quirks the same way as erts
do.
The configure script of the odbc application now also looks for
odbc libraries in lib64 and lib/64 directories when building on a
64-bit system.
The config.h.in file in the erl_interface application is now
automatically generated in instead of statically updated which
reduces the risk of configure tests without any effect.

Mattsson!
For the time being it is still possible to use the old GS based
version of the tool, but it is deprecated. The wxWidgets based
version is started by default.
A new tutorial has been added to the documentation. It is based
on Jayson Vantuyl's article
http://souja.net/2009/04/making-sense-of-erlangs-event-tracer.htm
l.
The functions et:trace_me/4 and et:trace_me/5 has been introduced
in order to replace the deprecated functions et:report_event/4
and et:report_event/5. Hopefully the new names makes it a little
more obvious what the intended usage of the functions are.
A print function has been added to the GUI, in order to enable
printing of sequence charts.
More functionality for hiding unwanted events has been added to
the GUI.
The max_events, hide_unknown and display_mode configuration
parameters to et_viewer is not used any more. Now the event cache
in the Viewer only contains those events that actually are
displayed in the GUI.
Some minor bugs has been fixed. Such as a cleaning up trace
patterns at termination and displaying events with detail level
100.

Optionally using data compression for copying Mnesia tables allows
the system to be tuned to eliminate network bottlenecks from
deployments where enough CPU is available to use zlib.
With this patch, running erl -mnesia send_compressed <level>
will enable compression for sending tables between nodes. The
compression level can be any integer in [0, 9], with 0 (the
default) meaning no compression (exactly the previous behaviour)
and 9 being the highest compression level.
To set any non-zero compression level at the sender, both nodes
must have the updated Mnesia modules (the receiver will work
according to the sender's configuration).

Now, when we have only the constant definition of a macro (without
arguments), we always use it. In all other cases, we try to find the
exact matching definition. We throw an error if we don't find it.
|
|
This feature simplifies the definition of macros by avoiding to have a
different name for each version (with different arities) of the same
macros. New rules:
- can have multiple definitions of the same macro with different arities
- cannot overload macro with the same arity
- the overloading of predefined macros (?MODULE, ?LINE, ...) is forbidden
- the directive '-undef' removes all definitions of a macro
