Erl_Interface 5.4
Improvements and New Features
As announced since the release of OTP 24, support for:
- version 4 node container types in the external term format are now
mandatory. That is, references supporting up to 5 32-bit integer
identifiers, and process and port identifiers with support for 64-bit data
storage. The distribution flag
DFLAG_V4_NC
is therefor now also mandatory. OTP has since OTP 24 supported this. Also note that the external format produced byterm_to_binary()
andterm_to_iovec()
will unconditionally produce pids, ports, and references supporting this larger format. - the new link protocol
introduced in OTP 23.3 is now mandatory. The distribution flag
DFLAG_UNLINK_ID
is therefor now also mandatory.
Due to the above, OTP 26 nodes will refuse to connect to OTP nodes from releases prior to OTP 24.

Two options have been added to
erl_call
. The-fetch_stdout
option fetches stdout data resulting from the code invoked byerl_call
. The-fetch_stdout
option disables printing of the result term. In order to implement the first of these two options a new function calledei_xrpc_from
has been added to erl_interface. For details see theerl_call

Support the new link protocol in order to be able to phase out the old link protocol in the future.
erl_interface
does not support setting up or removing links from theerl_interface
side, so the bug present with the old protocol did not effecterl_interface
. This since both participants of a link simultaneously needed to operate on the link in order to trigger the bug.Own Id: OTP-17270 Aux Id: OTP-17127

Erl_Interface 4.0.2
Fixed Bugs and Malfunctions
Integers outside of the range [-(1 bsl 32) - 1, (1 bsl 32) -1] were previously intended to be printed in an internal bignum format by
ei_print_term()
andei_s_print_term()
. Unfortunately the implementation has been buggy since OTP R13B02 and since then produced results with random content which also could crash the calling program.This fix replaces the printing of the internal format with printing in hexadecimal form and extend the range for printing in decimal form. Currently integers in the range [-(1 bsl 64), (1 bsl 64)] are printed in decimal form and integers outside of this range in Erlang hexadecimal form.

and friends erl_call -R
Own Id: OTP-13812
- starting with
Increased size of node incarnation numbers (aka "creation"), from 2 bits to 32 bits. This will reduce the risk of pids/ports/refs, from different node incarnation with the same name, being mixed up.

Added support to receive, decode, encode and send both bit strings and export funs (
fun M:F/A
).New functions
ei_decode_bitstring
andei_encode_bitstring
have been added in order to decode and encode bit strings where the number of bits is not necessary divisible by 8 (a whole number of bytes). The existing functionsei_decode_fun
andei_encode_fun
can now also handle export funs.Before this change, bit strings and export funs sent to an erl_interface c-node were encoded using an undocumented fallback tuple format. For bit strings
{Binary,BitsInLastByte}
and for export funs{M,F}
. Existing c-node implementations expecting these tuples must be changed to instead useei_decode_bitstring
andei_decode_fun
. As a temporary solution you can also build erl_interface with macroEI_COMPAT=21
or callei_set_compat_rel(21)
to receive the old fallback tuples.* POTENTIAL INCOMPATIBILITY *

erl_interface
/ei
refused to use node names with an alive name (the part of the node name preceding the @ sign) longer than 63 characters and a host name longer than 64 characters. The total amount of characters allowed in a node name (alivename@hostname) was thus limited to 128 characters. These limits applied both to the own node name as well as node names of other nodes. Ordinary Erlang nodes limit the node name length to 256 characters, which meant that you could not communicate with certain Erlang nodes due to their node name used.erl_interface
/ei
now allow the total amount of characters in a node name to be up to 256 characters. These characters may be distributed between alive name and host name in whatever way needed. That is, the maximum amount of characters in the alive name may be 254 and the maximum amount of characters in the host name may be 254, but in total the node name must not exceed 256 characters.Own Id: OTP-15781 Aux Id: ERIERL-356

Improvements and New Features
Remove generation of atoms in old latin1 external format in the distribution between erlang nodes,
erl_interface
, andjinterface
. The new utf8 format for atoms was introduced in OTP R16. An OTP 20 node can therefore not connect to nodes older than R16.Atoms that can be encoded using latin1 are still encoded by
term_to_binary()
using latin1 encoding. Note that all atoms will by default be encoded using utf8 in a future Erlang/OTP release. For more information see the documentation oferlang:term_to_binary/2

Improvements and New Features
Handle terms (pids,ports and refs) from nodes with a 'creation' value larger than 3. This is a preparation of the distribution protocol to allow OTP 19 nodes to correctly communicate with future nodes (20 or higher). The 'creation' value differentiates different incarnations of the same node (name).

ei: integer overflow in string/atom encoding
ei_encode_atom() and ei_encode_string() use strlen() to get the length of the buffer. As strlen() returns an unsigned long long and both ei functions take a signed integer, the length fields may overflow.

Erl_Interface 3.7
Improvements and New Features
compact IEEE 754 double encoding in external binary format for ei
- Implement the compact IEEE 754 double encoding in external binary format for ei. Encoding for ei now always produces the NEW_FLOAT_EXT format. Decoding and term printing handle both the old ERL_FLOAT_EXT encoding and the new NEW_FLOAT_EXT encoding.
- Legacy erl_interface code also handles the new encoding, but still produces the ERL_FLOAT_EXT encoding by default.
- Also enable the DFLAG_NEW_FLOATS distribution flag.
- ei_get_type() will return ERL_FLOAT_EXT regardless if the external format is encoded with ERL_FLOAT_EXT or NEW_FLOAT_EXT for doubles.
- Reduce the number of copies of the code for encoding and decoding doubles throughout ei and erl_interface by instead calling the ei encoding and decoding functions wherever possible.
- Restore commented-out float tests in ei_decode_SUITE and ei_encode_SUITE in lib/erl_interface/test. Modify them to make them match the style of other tests in the same suites.
These changes are based on an ei float patch from Serge Aleynikov originally submitted against R12B-2 in July 2008 and reworked by Steve Vinoski May 2010.

Cross compilation improvements and other build system 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
$ERL_TOP/INSTALL-CROSS.md
file. - Support for staged install using
DESTDIR. The old
broken
INSTALL_PREFIX
has also been fixed. For more information see the$ERL_TOP/INSTALL.md
file. - Documentation of the
release
target of the topMakefile
. For more information see the$ERL_TOP/INSTALL.md
file. make install
now by default creates relative symbolic links instead of absolute ones. For more information see the$ERL_TOP/INSTALL.md
file.$ERL_TOP/configure --help=recursive
now works and prints help for all applications withconfigure
scripts.- Doing
make install
, ormake release
directly aftermake all
no longer triggers miscellaneous rebuilds. - Existing bootstrap system is now used when doing
make install
, ormake release
without a precedingmake all
. - The
crypto
andssl
applications use the same runtime library path when dynamically linking againstlibssl.so
andlibcrypto.so
. The runtime library search path has also been extended. - The
configure
scripts oferl_interface
andodbc
now search for thread libraries and thread library quirks the same way aserts
do. - The
configure
script of theodbc
application now also looks for odbc libraries inlib64
andlib/64
directories when building on a 64-bit system. - The
config.h.in
file in theerl_interface
application is now automatically generated in instead of statically updated which reduces the risk ofconfigure
tests without any effect.
