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`.

This is a workaround for init:restart.
The root problem is that delete/purge_module does not
clean up internal hipe bookkeeping (hipe_mfa_info's)
properly.
Symptom: Execution of deallocated beam code.

Also allow mixed address families to bind, since the first address on
a multihomed sctp socket must be bound with bind, while the rest are
to be bound using sctp_bindx.
At least Linux supports adding address of mixing families.
Make inet_set_faddress function available also when HAVE_SCTP is not
defined, since we use it to find an address for bind to be able to mix
ipv4 and ipv6 addresses.

Putenv and getenv needs to convert to the proper environment
strings in Unicode depending on platform and user settings for filename
encoding. Also erlexec needs to pass environment strings in an appropriate
way for kernel to pick up. All environment strings on the command
line, as well as home directory, is now passed in UTF8 on windows
and in whatever encoding you have on Unix, kernel tries to convert all
parameters and environments from UTF8 before making strings.

When correcting OTP-10071, a new error was introduced in
erl_prim_loader. In order to improve ability to detect if a file was
inside the primary archive, all paths were flattened - i.e. "." and
".." were removed. This implementation had some faults, and it did not
take symlinks into account. This has been corrected.

This commit introduces no functional change. It only adds comments and
changes some function/variable names.
|

The following errors have been corrected:
* If primary archive was named "xxx", then a file in the same
directory named "xxxyyy" would be interpreted as a file named yyy
inside the archive.
* erl_prim_loader did not correctly create and normalize absolute
paths for primary archive and files inside it, so unless given with
exact same path files inside the archive would not be found. E.g. if
escript was started as /full/path/to/xxx then "./xxx/file" would not
be found since erl_prim_loader would try to match /full/path/to/xxx
with /full/path/to/./xxx. Same problem with ../.
* Depending on how the primary archive was built,
erl_prim_loader:list_dir/1 would sometimes return an empty string
inside the file list. This was a virtual element representing the
top directory of the archive. This has been removed.
Thanks to Tuncer Ayaz and Shunichi Shinohara for reporting and
co-authoring corrections.

If the mtime of an escript/primary archive file changes after being
added to the code path, correctly reload the archive and update the
cache.
The existing code didn't consider that it might be a zip archive and failed:
=ERROR REPORT==== 3-Aug-2011::09:21:21 ===
File operation error: bad_central_directory. Target:
/escript_archive/module.beam. Function: get_file. Process: code_server.
Thanks David Reid and Hakan Mattson.

User tags in a dynamic trace enabled VM are spread throughout the system
in the same way as seq_trace tokens. This is used by the file module
and various other modules to get hold of the tag from the user process
without changing the protocol.

Will catch system_limit and return error tuple instead. An uncaught

for gen_tcp:listen/1,2 for example.
