[New topics]

* ks/auth-specs (kernel) (2010-06-09) 1 commit
 - auth: Fix types and specs (1c51135)

* se/http_response_empty_phrase (erts) (2010-06-10) 1 commit
 - {packet,http} allow empty response phrase (288f54c)


* bg/safer-local_to_univ (erts) (2010-02-11) 1 commit
 - erl_time_sup.c: test for error return from mktime() (0f62f0b)

We will not include this branch in R13B04 for two reasons:

  o We are not 100% sure that this change is harmless on all
    platforms in all timezones.
  o We have an idea how the underlying problem can be fixed in
    the calendar module (only) and I plan to try it out after the
    release. We will keep this branch in pu as a reminder.

Action expected from: Bjรถrn Gustavsson

* db/tv_nthtail_fix (tv) (2009-12-01) 1 commit
 - Fix for tv which restarts while trying to open a table (28f1e36)

Since our long-term goal is to migrate from gs towards wx,
maintaining the old gs applications has a low priority for
the Erlang/OTP team. Therefore, we will accept patches that
seem sound, but we are unlikely to spend much of our own time
fixing bugs.

The author of this topic branch has found the real reason for
the problem, but uncovered additional issues.

Action expected from: The topic author - to decide whether to
include the topic branch (which is a workaround, but does eliminate
the crash) or to wait for a better fix from himself or someone else
with an interest to advance the topic.

* er/ei-decode_msg (erl_interface) (2010-03-11) 1 commit
 - Add function to decode distribution header (864091a)

Needs documentation and test cases.

Action expected from: Topic author

* gl/jinterface-pom (jinterface, otp) (2010-02-15) 2 commits
 - Exclude jinterface build artifact from git (5acf5fa)
 - Add pom.xml for jinterface build (aa68190)

The pom.xml file should be generated by the toplevel Makefile
since it contains the version number of Jinterface. This is
along the same line as the .app files are generated.
There should be a pom.xml.src that Makefile sed's into
pom.xml. See stdlib/src/Makefile.

Action expected from: Topic author

* jp/dependencies_makefile (compiler, erts) (2010-02-14) 3 commits
 - squash! eliminate dialyzer warning (434e2ca)
 - squash! fix snprintf for Windows (bf2708d)
 - Add dependencies Makefile generation to erlc(1) and compile(3) (7cbc437)

Approved in principle by the OTP Technical Board; now awaits a closer
review of the implementation.

Action expected from: Bjรถrn Gustavsson (the reviewer)

* kr/gs-browser (gs) (2010-02-10) 1 commit
 - Change lib/gs/src/tool_utils.erl to select multiple browsers other than
Netscape (802d159)

This topic branch introduces a new call to the deprecated regexp module.

Action expected from: Topic author or anyone else with an interest to
advance the topic


* bg/temp-hipe-fixes (compiler, hipe, kernel) (2010-03-15) 6 commits
 - Avoid crash by skipping compilation_SUITE:on_load/1 (234e13e)
 - Inline less aggressively for native-code compilation (9fcb48b)
 - Crudely fix return type for the lists:key{search,find,member}/3
 - seq_trace_SUITE: Don't native-compile (2a81b1a)
 - Disable native code if on_load is used (3befa76)
 - andor_SUITE: Don't native-compile (97aa2da)

This branch contains temporary workarounds to avoid failing test
cases and is never intended to graduate.

* cf/timer_tc (stdlib) (2010-04-06) 1 commit
 - Add timer:tc/2 to measure the elapsed time of anonymous functions

* jf/run_erl-disable-flow-control (erts) (2010-03-05) 1 commit
 - Teach run_erl RUN_ERL_DISABLE_FLOWCNTRL for disabling flow control

* jn/gen_stream (stdlib) (2010-05-17) 1 commit
 . Add new gen_stream behaviour for efficiently consuming serial streams

This topic branch has failing test cases. 

    We have now tested with and without this topic branch and when
    it is present that test case fails. We consider it proved
    to be guilty. The test case does not fail when run standalone
    so it seems to be tricky... Also, some of its own test cases
    fail sporadicly apparently since the assumption there shoul
    be no more processes after the test case does not hold;
    probably a timing issue.

Action expected from: Topic author.

* jr/cover-src-path (tools) (2010-04-23) 1 commit
 - Fix searching for source files in analyse_to_file/* (b9d5068)

* ks/cleanups (compiler, debugger, docbuilder, stdlib) (2010-04-10) 4

 - escript: Add more types to records (f2a2139)
 - debugger: Clean up as suggested by tidier (9e962d7)
 - docbuilder: Clean up as suggested by tidier (3647def)

* sb/make-files-like-erlc (tools) (2010-05-18) 1 commit
 - Change make:files to behave more like erlc (5e9d051)

* ta/asn1-reporting (asn1) (2010-04-23) 1 commit

 . Reference manual: Improve the documentation for external funs (de19b3c)
 . beam_loader: Support external funs in the literal pool (08ffb6b)

Some issues remain. Might be included in R14B if Bjorn manages
to find the time...

* hb/edoc (edoc) (2010-04-01) 1 commit
 . EDoc and Dialyzer specs and types (516e16c)

Temporarily dropped. Will be fixed to use updated dialyzer.

* pg/xmerl_scan_hex_entities (xmerl) (2010-06-07) 1 commit
 . Fix decoding of hex entities (&#xXXXX;) in xmerl_scan (36448fc)

The bug it fixes is recognized, but the fix in the branch is
not complete... The test case is in our internal 'dev' branch
but the test suites are not released yet due to remaining
copyright issues. We will fix the bug in a future release.
