As of this version, the global name server no longer supports nodes running
Erlang/OTP R11B.
|
|
|
|
The default value for Fun is start, not [] as the documentation used
to suggest.
Also, format [] with <c> instead of <em> since it is a code fragment,
not an emphasised word.

Print the name and arity of the function being compiled
if the v3_life compiler pass crashes to facilitate finding
out which part of the source code that triggered the problem.
|
|
The Erlang parser no longer duplicates the singleton type undefined in the
type of record fields without initial value.

* hawk/escript-add-create-and-extract:
Add type info for record fields
Remove the undocumented function escript:foldl/3
Make reltool independent of the function escript:foldl/3
Add functions to create and extract escripts
Add function zip:foldl/3 to iterate over zip archives
OTP-8521 hawk/escript-add-create-and-extract
Added function zip:foldl/3 to iterate over zip archives.
Added functions to create and extract escripts. See escript:create/2 and
escript:extract/2.
The undocumented function escript:foldl/3 has been removed. The same
functionality can be achieved with the more flexible functions
escript:extract/2 and zip:foldl/3.
Record fields has been annotated with type info. Source files as been
adapted to fit within 80 chars and trailing whitespace hasd been removed.

|
Fixed a crash in the certificate certification part.
|
|
While at it, adapt the source files to fit within 80 chars and
remove trailing whitespace.
|
|
It is possible to obtain the same effect with the
functions escript:extract/2 and zip:fold/3. See
escript_SUITE:escript_foldl/3 for a complete
emulation of the old escript:foldl/3 function.
|
|
The function is undocumented and is removed. The new implementation
uses the newly introduced functions escript:extract/2 and
zip:foldl/3. These new functions are documented (which implies that
they are a part of the public API).

Both reltool and rebar needs to parse escripts. They are currently
using an undocumented function called escript:foldl/3. It folds a
function over all files in the body of an escript. If the body
contains source code the function compiles it and the gives debug
compiled beam code to the fold fun. If the body is an archive the fun
is applied for all files in the archive.
Instead of making the undocumented function public, the new functions
escript:create/2 and escript:extract/2 has been introduced. Together
with the new zip:foldl/3 function they have the same functionality as
escript:foldl/3 in a more flexible and generic way.
escript:foldl/3 should be removed as soon as reltool and rebar has
been adopted to use the new functions. The simplest way for reltool
and rebar to do this is to just copy the code from
escript_SUITE:escript_foldl/3, which happens to provide a future
compatible implementation of an emulated escript:foldl/3 function.
I was quite hesitant when I introduced the compile_source option. It
feels that it does not belong there but the alternative felt worse.
The rationale for the compile_source option is that it is a bit
cumbersome to compile the source code, as the source in most cases is
partial. In order to do compile the source you need to know about some
internals in escript. Without compile_source I think that these
internals should be documented. Further you need to duplicate parts of
the code.
Without the compile_source option you need to first parse the source
to forms, using an undocumented function in epp with an extended
format of predefined macros which also is undocumented. Then you need
to investigate the forms to see if you need to add an export form for
main. When that is done you can run the rest of the compiler passes as
usual. It is not so much code (60 lines or so) to write, but I do not
want to urge people to write it. I actually wrote the code (see
escript_SUITE:escript_foldl/3) before I decided to introduce the
compile_source option.

This is the public interface of prim_zip:open/3,
which has been used in earlier releases by both
erl_prim_loader and escript. The new function
can be used as a replacement for the undocumented
function escript:foldl/3 that is likely to be
removed without further notice.
The error handling of prim_zip:open/3 (and
prim_zip:foldl/3) has been improved in order to
better suite a public interface. For example it
could happen that a file or a zlib port could be
left open in some errors cases.
The documentation of the FileSpec parameter to
zip:create/3 has been updated to show that
file info can be explicitly specified. A FileSpec
may contain {Filename, binary(), #file_info{}}
elements. The function zip:create/3 was already
prepared to partly support this, but now after
a few minor fixes it is fully supported.

* ml/documentation_apostrophe_fix:
Correct grammatical problems in conjunction with 'its'
Change all incorrect occurrences of it's to its
OTP-8523 ml/documentation_apostrophe_fix
|
|
|
|
The documentation (*.xml) in the otp tree has a common grammatical
problem, "it's" and "its" are often interchanged. That is annoying
for some readers.
This commit consists entirely of "it's" -> "its" changes. I went
through every .xml file in the tree. If there are any remaining
bugs of this type, it's because I missed them, not because I
didn't look.

'cond' is an experimental feature that was never completed.

Only release the source code and an Emakefile, so that ts:run()
can build the tests just before running them.
The main advantage of building the tests suite like that is
that the turn-around time for developing new test cases are
much faster: just edit the appropriate file and do ts:run().

Two modules were clearly copied and adapted from the megaco
test suite. Change the name of the application being tested
in a comment to "asn1" and also remove out-commented code
that refers to "megaco".
|

On Windows, $ERL_TOP contains a cygwin-style pathname
that can be used in Makefiles to (for instance) include
other Makefiles, but must not be passed to non-cygwin programs
such as "erlc". Therefore, using compiler options such as
"-I $(ERL_TOP)/lib/test_server/include" will not work on
Windows.
Fix this problem by include "test_server.hrl" using
-include_lib() instead of -include(). That works because
-include_lib() searches for include files in the code path
without the need for any -I options.

* bg/sasl-infinity:
Prepare patch release
sasl: Use gen_server:call/3 with infinity timeout
OTP-8506 bg/sasl-infinity
Use an infinity timeout in all calls to gen_server:call() in the sasl
application.

This problems occurs in some recent versions of Emacs.

Driver threads, such as async threads, using <seealso
marker="erl_driver#ErlDrvPDL">port data locks</seealso> peeked at the port
status field without proper locking when looking up the driver queue.

A race condition in os:cmd/1 could cause the caller to get stuck in
os:cmd/1 forever.

A call to the BIF unregister(RegName) when a port had the name RegName
registered in the runtime system without SMP support caused a runtime
system crash. (Thanks to Per Hedeland for the bugfix and test case.)

ODBC now handles the types SQL_WCHAR and SQL_WVARCHAR. ODBC also has a new
connection option to return all strings as binaries and also expect strings
to be binaries in the param_query function. This provides some but not a
full unicode support.
|
|
The empty record (no fields) is now considered typed.
It is more consistent than before; the base case is
the logical one.
A record is typed iff all its fields are typed.
A record is tagged 'typed' iff it is typed.
|

The erlang pretty printer (erl_pp) no longer quotes atoms in types.

gen_server:call/2,3 now sets up a monitor to make sure that
it will be noticed if the called process dies. Therefore,
there is almost never a good reason to use gen_server:call/2
with its default 5 seconds timeout. Use gen_server:call/3
with the 'infinity' timeout instead.
To make sure we use the 'infinity' timeout every time,
wrap the to call gen_server:call/3 in a local call/1 function
in each module.
|
|
Having various type declarations in the file.hrl file was once upon a time
necessary since the system could not really handle remote types. Now it can
and these declarations should not be there but appear in file.erl instead.
This means that files that need to use these types can refer to them using
a remote type reference, and not having to include file.hrl - at least not
for this reason.
