2010-03-16Remove the undocumented function escript:foldl/3Håkan Mattsson
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.
2010-03-16Make reltool independent of the function escript:foldl/3Håkan Mattsson
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).
2010-03-16Add functions to create and extract escriptsHåkan Mattsson
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.
2010-03-16Add function zip:foldl/3 to iterate over zip archivesHåkan Mattsson
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.

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

2010-03-11asn1 tests: Let ts:run() build the testsBjörn Gustavsson
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".
2010-03-11asn1 tests: Don't refer to $ERL_TOP in compiler optionsBjörn Gustavsson
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.

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.
2010-03-09OTP-8503 stdlib: records with no fields is considered typed by eppHans Bolinder
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.

2010-03-08sasl: Use gen_server:call/3 with infinity timeoutBjörn Gustavsson
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.
2010-03-07file.hrl: Move out type declarationsKostis Sagonas
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.
