* mhssler/add-os-unsetenv/OTP-11446:
erts: remove ?line macro in testcases
Update primary bootstrap
Add os:unsetenv/1
|
|
New BIF os:unsetenv/1 which deletes an environment variable and
returns 'true'.
Does not change any old functionality.
Calls the libc function unsetenv(3) on UNIX and
SetEnvironmentVariableW(key, NULL) on Windows. The unicode support
is the same as for os:getenv and os:putenv.

'one-to-may' should be 'one-to-many'
|
|
|
|
Most notes.xml files will be updated in every release and cause
the kind of the problems described in the previous commit.

* raimo/linux-network-namespace-sockopt/OTP-11157:
Document socket option 'netns'
Rudimentary test
Make netns option value a string
Implement netns for SCTP + bugfixes
Implement netns option for TCP and UDP
Implement emulator netns support for TCP and UDP

* fh/start-all/OTP-11250:
kernel: fix documentation regarding ensure_all_started endtag
Updated primary bootstrap
Add application:ensure_all_started/1-2
|
|
|
|
|
|
|
|
|
|
This adds two new functions to the application module that will
recursively look for missing dependencies to start the entire dependency
chain of a given application, and then the application itself, if
possible.
Its entire behavior is based on the currently existing 'start/1-2'
functions, which will report dependencies that have not yet been started
and other problems encountered. 'ensure_all_started/1-2' will use this
information the way any programmer would manually do it to automate the
process.
This kind of functionality, while not OTP-ish (releases do this start
sequence for the user), is still useful for testing purposes, quick
demonstrations, and programmers who do not wish or know how to use OTP
releases.
The function returns '{ok, StartedApps}' for all started or already
started applications (already started are omitted from the list), and
will return '{error, {AppName, Reason}}' on a failure to allow users to
rapidly know why the function failed.
Note that no specific check is made for direct or indirect circular
dependencies between applications, and these will make the function go
in an infinite loop.

* hb/file_name_type/OTP-10852:
Introduce new type file:name_all()
|
|
|
|
|
|
|
|
The recommended type for filenames is a list of characters (which
may be Unicode characters greater than 255). Change the
file:filename() to reflect that.
For the filename module we still need a type that can be either
a string or a binary, so we need to introduce the type
file:filename_all().

* vd/code_get_mode/OTP-10823:
Added name prefix to code.xml
Add a new function code:get_mode() can be used to detect how the code servers behaves
|
|
|
|
servers behaves
Rationale:
Some applications (like erlide) have code to be loaded dynamically on a
node. It may be slow to load everything upfront every time, so if the
node is in interactive mode, we would like to just append to the load
path. Currently, there is no direct way to detect if the node is running
in embedded mode or not so that we can do the right thing.

The type ascii_string() in the base64 module has been corrected.
The type file:file_info() has been cleaned up.
The type file:fd() has been made opaque in the documentation.
The type nodes() has been removed from erl_bif_types.erl.

* bjorn/kernel/undefined-function-handler/OTP-10617:
Teach error_handler to call '$handle_undefined_function'
|
|
* bjorn/remove-packages/OTP-10348:
compile: Remove vestiges of package support
Remove documentation about packages
|
|
* sal/get_env/OTP-10694:
Moved documentation in a separate entry
Removed obsolete ?line macro
Add application:get_key/3
|
|
|
|
|
|
The new function provides a default value for a configuration
parameter.

* fdm/file-allocate/OTP-10680:
Update preloaded prim_file.beam
erts: Fix xcomp configure for fallocate
Add file:allocate/3 operation
|
|
This operation allows pre-allocation of space for files.
It succeeds only on systems that support such operation.
The POSIX standard defines the optional system call
posix_fallocate() to implement this feature. However,
some systems implement more specific functions to
accomplish the same operation.
On Linux, if the more specific function fallocate() is
implemented, it is used instead of posix_fallocate(),
falling back to posix_fallocate() if the fallocate()
call failed (it's only supported for the ext4, ocfs2,
xfs and btrfs file systems at the moment).
On Mac OS X it uses the specific fcntl() operation
F_PREALLOCATE, falling back to posix_fallocate() if
it's available (at the moment Mac OS X doesn't provide
posix_fallocate()).
On any other UNIX system, it uses posix_fallocate() if it's
available. Any other system not providing this system call
or any function to pre-allocate space for files, this operation
always fails with the ENOTSUP POSIX error.

Examples overflowing the width of PDF pages have been fixed.
The remaining warnings are due to table cells, and require more
work.
|
|
|
|
Expect modifications, additions and corrections.
There is a kludge in file_io_server and
erl_scan:continuation_location() that's not so pleasing.
