An ECONNRESET is a socket error which tells us that a TCP peer has sent
an RST. The RST indicates that they have aborted the connection and
that the payload we have received should not be considered complete. Up
until now, the implementation of TCP in inet_drv.c has hidden the
receipt of the RST from the user, treating it as though it was just
a FIN terminating the read side of the socket.
There are many cases where user code needs to be able to distinguish
between a socket that was closed normally and one that was aborted.
Setting the option {show_econnreset, true} enables the user to receive
ECONNRESET errors on both active and passive sockets.
A connected socket returned from gen_tcp:accept/1 will inherit the
show_econnreset setting of the listening socket.
By default this option is set to {show_econnreset, false}.
Note that this patch only enables the reporting of ECONNRESET when
the socket is being read from. It does not report ECONNRESET (or
EPIPE) when the user tries to write to a connection when an RST
has already been received. Currently the TCP implementation in
inet_drv.c hides all such send errors from the user in favour
of returning {error, close}. A separate patch will be needed to
enable the reporting of such errors.

Make code_server be responsible for finding the architecture and deciding
whether to try to load native code, in order to avoid repeated calls to
system_info(hipe_architecture) and clumsy uses of try/catch to test if hipe
is enabled.
|
|
Make hipe_unified_loader not call system_info(hipe_architecture) repeatedly.
Also clean up some ugly architecture-dependent case switches.

* richcarl/ac_tab-concurrency:
Use read_concurrency for application environment
|
|
We want to have the core applications of Erlang/OTP free from any
dialyzer warnings. Eliminate the warnings for unmatched returns
that were introduced in 7309ff4c3832.
|
|
The current implementations of inet:parse_ipv6_address/1 and
inet:parse_ipv6strict_address/1 permit address strings which have an
unlimited number of leading zeros. Addresses such as:
"0000000000000000000000000000000ffff::"
"::00000000000000000000000000000000000000000000000000000000"
"::0000000f435:1"
If we are using this facility to validate string representations of
IPv6 addresses, then we would end up validating addresses which are
non-conformant (with respect to RFC 4291 section 2.2) and potentially
dangerous.
This patch ensures that each segment of an IPv6 address has a maximum
of 4 hex digits.

* richcarl/md5-fixes:
code: Correct type spec for code:make_stub_module/3

|
* MSch/patch-1:
Remove erlang:display/1 calls
|
|
|
|
e47490f83e561a changed the size of Info argument tuple (third argument)
for code:make_stub_module/3 from 2 to 3, but did not update the
spec in code.erl.
|
|
* richcarl/md5-fixes:
Set module_info md5 for native modules properly
Add module_info entry for native code
Gracefully handle empty md5 field in module_info
Remove 'imports' key from spec of get_module_info()
|
|
|
|
7309ff4c38325 introduced a mismatch between
load_native_code_for_all_loaded/0 and its spec. We could just delete
spec, but it is cleaner to ensure that the function always returns
'ok'.

Use the md5 of the native code chunk instead of the Beam code md5.
|
|
* bjorn/kernel/code-loading:
kernel application: Start code server first
code: Reduce overhead of native code checking for loaded modules
|
|
When the code server has started, it will read the .beam files
for all loaded modules to see whether they contain native code
that should be loaded. To make that as fast as possible when
we have no native code, start the code server as early as possible
to minimize the number .beam files that must be read from disk.
The code server does not use the 'file' module, so it is OK to
start the code server before starting the file_server process.
On my computer, the time for checking the loaded modules for
native code is reduced from roughly 2 ms to 1.5 ms.
|
|
When the code server has been started, the function
load_native_code_for_all_loaded/0 will check whether the .beam
files for all loaded modules contain any native code. If there
is native code, it will be loaded.
If there is no native code, on my computer the check will take about
10 ms. That time can be reduced to about 2 ms if we replace the call
to code beam_lib:chunks/2 with a call to prim_file:read_file/1 to read
the file and a call to code:get_chunk/2 to check whether the chunk for
native code is present.
Furthermore, the entire check can be spawned off to a separate
process and done in parallel with OTP starting up.

* peppe/jcl_mode_improvements:
Fix problem with unitialized edlin text buffer
Fix shell crash when in switch command mode
OTP-12673
|
|
|
|
Also make it possible to copy text buffer from current group
process to the JCL mode
|
|
The user_drv process can crash if ctrl-y is pressed when in switch command mode (ctrl-g).
This is due to switch mode using edlin to parse the input.
And edlin uses the process dictionary to store the kill_buffer.
However the kill_buffer is undefined if not initialized by edlin:init/0
which makes the user_drv process crash since edlin is calling list:reverse/2 with undefined.
Fix calles edlin:init/0 once before server_loop is entered.
|
|
|
|
Let gen_tcp:controlling_process/2 and inet_sctp:connect/[45] propagate
prim_inet:setopt/3 errors instead of having them generate badmatch
exceptions.

The old time API is based on erlang:now/0. The major issue with
erlang:now/0 is that it was intended to be used for so many
unrelated things. This tied these unrelated operations together
and unnecessarily caused performance, scalability as well as
accuracy, and precision issues for operations that do not need
to have such issues. The new API spreads different functionality
over multiple functions in order to improve on this.
The new API consists of a number of new BIFs:
- erlang:convert_time_unit/3
- erlang:monotonic_time/0
- erlang:monotonic_time/1
- erlang:system_time/0
- erlang:system_time/1
- erlang:time_offset/0
- erlang:time_offset/1
- erlang:timestamp/0
- erlang:unique_integer/0
- erlang:unique_integer/1
- os:system_time/0
- os:system_time/1
and a number of extensions of existing BIFs:
- erlang:monitor(time_offset, clock_service)
- erlang:system_flag(time_offset, finalize)
- erlang:system_info(os_monotonic_time_source)
- erlang:system_info(time_offset)
- erlang:system_info(time_warp_mode)
- erlang:system_info(time_correction)
- erlang:system_info(start_time)
See the "Time and Time Correction in Erlang" chapter of the
ERTS User's Guide for more information.

* wmalik/minor-fixes:
Fix proc_lib doc
Remove commented out code
Fix make_hash description
|
|
This commit introduces two BIFs:
* erts_internal:map_type/1
* erts_internal:map_hashmap_children/1
erts_internal:map_hashmap_children/1 is only intended for use within
erts_debug:size/1 since the internal hashmap node is not allowed to
leak anywhere.

When a file was opened with some unicode encoding, file:read_line/1
could return unicode codepoints > 255 in list mode and wrong error
message in bin mode.
Chose to break out 'get_line' functionality from get_chars/5 since
'get_until' handling is different (comes from io module which should
return unicode lists) and seems to have its own (doc?) problems.
