Add enif_raise_exception function to allow NIFs to raise error
exceptions holding any Erlang terms. This does not replace or
deprecate the enif_make_badarg function, though, because raising
badarg errors is so idiomatic in NIFs. Reimplement enif_make_badarg on
top of enif_raise_exception. Add new tests for enif_raise_exception
for both normal and dirty NIFs. Add documentation for
enif_raise_exception.
|
|
Sverker Eriksson came up with the following idea: to handle a future
ability for NIFs to raise more than just badarg exceptions, modify the
recently-added enif_has_pending_exception function to take a second
argument: a pointer to ERL_NIF_TERM. If this argument is a null
pointer, ignore it. Otherwise, if the first argument, an ErlNifEnv*,
has an associated exception, set the pointed-to ERL_NIF_TERM of the
second argument to the value of the exception term. Add new tests and
documentation for this modification.

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.

* essen/zlib-windowbits:
Update zlib:zwindowbits/0 type to accept 8 and -8
OTP-12564
|
|
|
|
Add a check to enif_make_double to see if its double argument is
infinity or NaN, returning a badarg exception if it is. Change the
erl_nif documentation to specify that enif_make_double returns a
badarg exception if its double argument is either infinity or NaN. Add
tests to nif_SUITE for this change.
Add checks to the enif_make* functions for atoms to prevent the
creation of atoms whose name lengths are greater than the allowed
maximum atom length. The enif_make_atom and enif_make_atom_len
functions now return a badarg exception if the input string is too
long. The enif_make_existing_atom and enif_make_existing_atom_len
functions return false if the input string is too long. Change the
erl_nif documentation to reflect the changes to these functions. Add
tests to nif_SUITE for these changes.
Add a field to ErlNifEnv to track that a NIF has raised an exception
via enif_make_badarg. If a NIF calls enif_make_badarg but then ignores
its return value and instead tries to return a non-exception term as
its return value, the runtime still raises a badarg. This is needed to
prevent enif_make_badarg values resulting from calls to
enif_make_double, enif_make_atom, or enif_make_atom_len from being
erroneously stored within other terms and returned from a NIF. Calling
enif_make_badarg but not returning its return value has been
documented as being illegal ever since enif_make_badarg was added, but
the runtime has not enforced it until now. Add tests for regular and
dirty NIFs to ensure that calls to enif_make_badarg result in badarg
exceptions even if a NIF fails to return the result of
enif_make_badarg as its return value. Add documentation to
enif_make_badarg to specify that calling it raises a badarg even if a
NIF ignores its return value.

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.

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).
```
