Corrected year in license header.
OTP-9386 - Calling ssh_sftp:stop_channel/1 resulted in that the trap_exit flag was set to true for the invoking process.

* hb/correction_zip_open/OTP-9472:
Fix a bug in zip:zip_open/1,2.
|
|
The example is for converting from infix to prefix. This change
uses to correct ordering of the triplet.
|
|
|
|
zip:zip_open/1,2 did not accept binary archives.
Also corrected the contracts of t/1 and tt/1.

The contracts of zip:zip_list_dir/1 and zip:zip_get/2 have been
corrected.

Fixed dialyzer warning occuring on binary comprehension of form
"<< <<>> || {A, B} <- [{a, b}] >>" caused by default clause
inserted by compiler. Since this clause is different from the
case of list comprehension, dialyzer fails to suppress that warning.

Constructing binaries using the bit syntax with literals sizes
that would not fit in an Uint will either cause an emulator crash
or the loading to be aborted.
Use the new TAG_o tag introduced in the previous commit to make sure
that the attempt to create huge binary literals will generate a
system_limit exception at run-time.
|
|
The handling of large values for other tags than TAG_i (integer) is
buggy. Any tag value equal to or greater than 2^40 (5 bytes) will
abort loading. Tag values fitting in 5 bytes will be truncated to 4
bytes values.
Those bugs cause real problems because the bs_init2/6 and
bs_init_bits/6 instructions unfortunately use TAG_u to encode literal
sizes (using TAG_i would have been a better choice, but it is too late
to change that now). Any binary size that cannot fit in an Uint
should cause a system_limit exception at run-time, but instead the
buggy handling will either cause an emulator crash (for values in the
range 2^32 to 2^40-1) or abort loading.
In this commit, implement overflow checking of tag values as a
preparation for fixing the binary construction instructions. If any
tag value cannot fit in an Uint (except for TAG_i), change the
tag to the special TAG_o overflow tag.
|
|
We want to make sure that a tag/type name is not defined more than
once and that we don't define too many primitive tags. Primitive
tags must be named with lowercase letters (or they will be confused
with variable names in transformations in the ops.tab file).
|
|
Attempting to construct <<0:((1 bsl 32)-1)>>, the largest bitstring
allowed in a 32 bit emulator, would cause an emulator crash because
of integer overflow.
Fix the problem by using an Uint64 to avoid integer overflow.
Do not attempt to handle construction of <<0:((1 bsl 64)-1>> in
a 64-bit emulator, because that will certainly cause the emulator
to terminate anyway because of insufficient memory.
