2010-03-30erl_parse: Remove more stray 'cond' supportBjörn Gustavsson
Unfortunately, commit 1e2ecf8c492b6d499880b8676e3c1fe0c5793103 removed all cond support except for two lines.
2010-03-26Fix spelling: "loose" is not a verbMagnus Henoch
"Lose" means not "not win", but "loose" means "not tight". Change "loose" to "lose" where appropriate.
2010-03-17OTP-8522 Avoid duplicated 'undefined' in record field typesHans Bolinder
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.
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.
2010-03-16Add 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.

2010-03-16Change all incorrect occurrences of it's to itsMatthias Lang
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.

2010-03-10Fix a crash when using an undefined record name as a typeKostis Sagonas
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.

The erlang pretty printer (erl_pp) no longer quotes atoms in types.
2010-03-09Merge branch 'ks/types' into devErlang/OTP
* ks/types: file.hrl: Move out type declarations kernel: Add types and specs OTP-8494 ks/types
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.

2010-03-02OTP-8470 stdlib: epp bugHans Bolinder
The Erlang code preprocessor (epp) sent extra messages on the form {eof,Location} to the client when parsing the file attribute. This bug, introduced in R11B, has been fixed.

2010-02-10OTP-8434 Improved handling of typed records in escriptsHåkan Mattsson
2010-02-10Add count_children/1 to supervisor.erl to determine the number ofJay Nelson
children being managed without the memory impact of which_children/1 The function which_children/1 returns a list of the child processes currently being supervised, but it has the penalty of creating a new list thereby consuming more memory. In low memory situations it is often desirable to know which supervisor may have generated many processes, but the act of discovering the culprit should not cause the node to crash (or worse a different node if the kernel kills one randomly). The new function count_children/1 can give an indication of which supervisor is taxing resources the most without adding to the burden. Rather than creating a new list, it walks the supervisor's internal children structure using an accumulator function so that any used memory can be incrementally collected yet the resulting count can still be obtained. The return result of count_children/1 is a property list of counts containing: - {specs, Total_Num_Child_Specs} - {active, Num_Active_Child_Processes_Of_Supervisor_Or_Worker_Type} - {supervisors, Num_Supervisor_Type_Children_Including_Dead_Processes} - {workers, Num_Worker_Type_Children_Including_Dead_Processes} This patch was made in response to mailing list discussions of the problem diagnosing heavily taxed production systems. I cannot find the original request, but http://www.erlang.org/cgi-bin/ezmlm-cgi/4/35060 is my original post of the patch.

2010-02-09Allow recursive types and check for undefined typesKostis Sagonas
Contains four kinds of changes: * Allows recursive types and type definitions to be in any order. * Because the checking is not performed from top to bottom, there is a separate pass which checks for undefined module-local types. * Behaviour callbacks which allow specs in them. * Clean up the code as suggested by tidier.
