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.

* raimo/infinite-loop-gethostbyname/OTP-12133:
Restore lookup order after test
|
|
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.

* dgud/kernel/unicode_file_read/OTP-12144:
kernel: Add test for unicode mode in file
kernel: Fix file:read_line/1 unicode error handling
|
|
|
|
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.

Commit 7e8f5a776cbfa376e03369d058a90c8dd9f217fc (importing R11B-3)
updated zlib, which had changed what values it accepts for window
bits from 9-15 to 8-15.
From deflate.c:
- windowBits < 9 || windowBits > 15 || level < 0 || level > 9 ||
- strategy < 0 || strategy > Z_HUFFMAN_ONLY) {
+ windowBits < 8 || windowBits > 15 || level < 0 || level > 9 ||
+ strategy < 0 || strategy > Z_FIXED) {
return Z_STREAM_ERROR;
}
+ if (windowBits == 8) windowBits = 9; /* until 256-byte window bug fixed */
In inflate.c 8 was already an accepted value.
This commit updates OTP to also accept the values 8 and -8.

An erroneous lookup option is needed to trigger the bug, and that can only
enter the system from a parsed file e.g .inetrc.
Pinpointed by Emil Holmström
|
|
I was going through application_controller.erl looking for why
something was behaving a certain way, saw a comment about removing
this duplicated code one day, and decided to move that a step forward.

This functionality may be useful for compressed streams with high
compression ratio (in case of gzip it may be up to x1000), when
small amount of compressed data will produce large amount of
uncompressed output. This may lead to DoS attacks, because
server easily goes out of memory.
Example of such high compression ratio stream:
```
dd if=/dev/zero of=sparse.bin bs=1MB count=100 # 100mb of zeroes
gzip sparse.bin # 95kb sparse.bin.gz
$ erl
> {ok, Compressed} = file:read_file("sparse.bin.gz"),
> 97082 = size(Compressed),
> Uncompressed = zlib:gunzip(Compressed),
> 100000000 = iolist_size(Uncompressed).
```

The hipe_bifs:make_native_stub/2 and hipe_bifs:get_emu_address/1
BIFs were originally used by hipe_unified_loader.erl, but the
code been obsolete and disabled for ages.
Remove the BIFs and all references to them.
In hipe_unified_loader.erl, remove the no-op emu_make_stubs/1
function.
