* saleyn/float_to_list_2/OTP-10837:
Fix memory leak in error case
Use macros instead of constants
float_to_list/2 changed rounding and cosmetic cleanup
|
|
* pan/unicode_filename_warnings:
Add file:list_dir_all/1 and file:read_link_all/1
prim_file: Add list_dir_all() and read_link_all()
Teach prim_file:set_cwd() to avoid entering non-translatable directories
Make prim_file skip invalid filenames in unicode mode
prim_file: Refactor functions that return filenames
prim_file: Refactor handling of responses
prim_file: Always open non-file ports in binary mode
Test that list_dir("non-existing-dir") fails with the correct error
|

We have decided that we don't want to deal with the compilations
of prim_file:get_cwd() returning a binary when the current
directory name cannot be translated losslessly to a list (i.e.
when the run-time system was started with +fnu and the current directory
name contains bytes that are not part of a valid UTF-8 sequence).
Therefore, if prim_file:set_cwd() is given a binary as the pathname,
we will need to check the binary to make sure it can be translated
to a list. We will introduce a new BIF, called prim_file:is_translatable/1,
which will check both filename encoding mode, and if it is one of
Unicode modes, the binary as well.
We don't need to do anything special if prim_file:set_cwd() is passed
a list.

The fix affects list_dir and read_link. Raw filenames are now
never produced, just consumed even if +fnu or +fna is used on
Linux etc.
This also adds the options to get error return or error handler
warning messages with +fn{u|a}{i|w|e} as an option to erl.
This is still not documented and there needs to be other versions
of read_dir and read_link to facilitate reading of all types
of filenames and links.
A check that we will not change to an invalid directory is also needed.

* bjorn/compiler/crash/OTP-10794:
BEAM loader: Handle element(Pos, not_a_tuple)
|
|
* sverk/packet-http-string-maxlen:
erts: Increase length of well formed header names from {packet,http}
OTP-10824

Changed rouding to round half-way up instead of down.
Cosmetic cleanup and error handling of additional edge cases.
|
|
The loader failed to load non-optimized BEAM code generated from:
element(2, not_a_tuple)
Commit ece4c17d2288a3161c995 introduced such code into
core_fold_SUITE, leading to core_fold_no_opt_SUITE and
core_fold_post_opt_SUITE failing to load.
|
|
To ease matching of unrecognized header field names we convert them
from case insensitive to the format Sec-Websocket-Version
with capital letters only first and after hyphens.
Earlier only header names up to 20 characters were converted to this
format due to internal buffer limitation. Raising this limit to 50
is a pragmatic solution for existing long header names such as
Sec-Websocket-Version, while valid header names longer than 50 characters
are not very probable.
|
|
The BEAM loader will put floating point constants into the
literal pools for the module, but it will not check for duplicates.
We can do much better by having the compiler use the literal
pool for floating point constants.

* sverk/code_write_permission-assert:
erts: Fix ASSERT crash in erts_try_seize_code_write_permission
|
|
ASSERT(code_writing_process != c_p);
The assert was actually harmless and could be removed as one solution.
But I think it's better to keep it as a way to catch bugs that would
otherwise lead to horrible deadlocks if a thread "forgets" to call
erts_release_code_write_permission().
As a result erts_release_code_write_permission() must be called BEFORE
resuming the suspended process.

This BIF solves a problem of float_to_list/1 that doesn't allow
specifying the number of digits after the decimal point when
formatting floats.
float_to_list(Float, Options) -> string()
Float = float()
Options = [Option]
Option = {decimals, Decimals::0..249} |
{scientific, Decimals::0..249} |
compact
Returns a string which corresponds to the text representation of
a `Float` formatted using given options.
When decimals option is specified the returned value will contain
at most `Decimals` number of digits past the decimal point.
When `compact` option is provided the trailing zeros at the end
of the list are truncated (this option is only meaningful together
with the `decimals` option). When `scientific` option is provided,
the float will be formatted using scientific notation with
`Decimals` digits of precision. If `Options` is `[]` the function
behaves like `float_to_list/1`. When using `decimals` option and
the number doesn't fit in the static internal buffer of 256 bytes
the function throws `badarg`.
