What's cooking in erlang/otp (2010-02-18)

This is the final What's cooking before the R13B04 release.

I have updated the Stalled section with some more branches,
and added an "Action expected from" line to each, to make
it clear who is responsible for making the next step to
advance the topic.

I will take this opportunity to thank everyone that have
sent us patches. There are currently in the dev branch
one or more commits from 32 persons from outside the
Erlang/OTP team (a few more patches have been included in
some way or another into the release without being visible
in the history in the git repository). I have not counted,
but I think we have never included so many pathes from
open-source contributors in any previous release.

------------------------------------------------------------
[New topics]

* bg/compiler-bugs (otp) (2010-02-16) 1 commit
 - bug: inlining a module causes an internal compiler error (f77e8aa)

Reminder for a (low priority) bug to fix after the R13B04 release.

* gl/jinterface-pom (jinterface, otp) (2010-02-15) 2 commits
 - Exclude jinterface build artifact from git (37e9289)
 - Add pom.xml for jinterface build (5405d48)

* mh/ssh_channel-init-no-catch (ssh) (2010-01-25) 1 commit
 - Remove pointless catch from ssh_channel:init/1. (bb7eaa5)

* ra/include-public_key-in-ssh (ssh) (2010-01-20) 1 commit
 - Added public_key among ssh applications. (3a0c2c5)

------------------------------------------------------------
[Stalled]

* at/odbc_osx_fix (odbc) (2009-11-30) 1 commit
 - Workaround broken ODBC implementation on OSX 10.5 (88c71c9)

The patch in itself is good. It solves the problem on Mac OS X
in the only way that seems possible. Unfortunately, our
test cases fail on Linux, and fixing it seems to require a
backward-incompatible change to the API of the odbc module or
ugly workarounds. The reviewer (Jakob Cederlund) will email
the details and suggest and/or implement a solution.

Action expected from: OTP/Jakob Cederlund

* 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: Björn Gustavsson

* db/tv_nthtail_fix (tv) (2009-12-01) 1 commit
 - Fix for tv which restarts while trying to open a table (abe0759)

I should have put this into the stalled state earlier.

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.

* 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: Björn 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

[Cooking]

* bd/mnesia-activity-subscription (mnesia) (2010-02-12) 1 commit

 - Disable native code if on_load is used (bd4fe28)

cases and is never intended to graduate.
