2012-03-20Fix reselecting bug on OS XLukas Larsson
Since stop_select is called at an arbitrary point in the future it would sometime not be alled before the tcp driver started selecting on the fd. So now ERL_DRV_USE_NO_CALLBACK is used so that the stop_select call is never made. This seems to only have happened OS X.
2012-03-20Fix bug when sending long files using selectLukas Larsson
The return value from efile_sendfile was not consistent inbetween platforms. The API should now be working as it was intended. OTP-9994

2012-03-20Fix memory leak when sendfile process crashesLukas Larsson
We use the fact that file_flush is called when there is data in the driver queue when a port is closed to ensure that all data is cleaned up as it should. OTP-9993

2012-03-16Extend erlang:port_info/1,2 to show the OS pid of a spawned processMatthias Lang
When spawning OS (unix) processes with erlang:open_port, store the resulting unix pid so that it can be queried later on using erlang:port_info/1,2.
2012-03-15Fix port leaks in zlibSverker Eriksson
zip,unzip,gzip,gunzip,compress and uncompress did not close the port when given invalid data argument. Fixed by putting close in "try-after". A closed port could in same cases get stuck in limbo due to data in io-queue. Fixed by adding a flush callback.

OTP-9974
2012-03-07erts: Fix assert failure when code_server exits "during" commitSverker Eriksson
Simplify by removing the support of abort_staging after end_staging.
2012-03-06erts: Fix memory leak in code loadingSverker Eriksson
All magic binaries returned by prepare_loading/2 was leaking. prepare_loading/2 left the reference count as 2 of the magic binary when it should be 1 (only owned by the returned term).
2012-02-24erts: Set correct default tracing when loading codeSverker Eriksson
Default trace (on_load) was lost in commit 64bcf5db63d73fe when load_module/2 was split.

2012-02-23erts: Refactor code loading with renamingSverker Eriksson
Rename lock_code_ix as seize_code_write_permission. Don't want to call it a "lock" as it can be held between schedulings and different threads and is not managed by lock checker. Rename "activate" staging as "commit" staging. Why not be consistent and use git terminology all the way.
2012-02-23erts: Seize code_ix lock when updating trace settingsSverker Eriksson
We want to avoid the race when trace settings are done in the time gap while a code stager process is waiting for thread process before commiting and releasing code_ix lock.
2012-02-23erts: Switch order between code_ix lock and thread blockingSverker Eriksson
Make for simpler code when we just can block threads and continue without having to release code_ix lock and repeat code lookups to avoid race.
2012-02-21erts: Fix race bug in finish_after_on_loadSverker Eriksson
Must block system before looking up module to not race with other "code upgrader".
2012-02-21erts: Refactor export staging lockSverker Eriksson
Renamed it export_staging_lock and made change it to ordinary mutex.
2012-02-21erts: Activate staged code in a thread safe waySverker Eriksson
Activation of staged code is scheduled for a later moment when all schedulers have done a full memory barrier. This allow them to read active code index while executing without any memory barriers at all.
2012-02-21Add missing HAVE_IN6 && AF_INET6 ifdefPeer Stritzinger
This prevents building for operating systems that do not yet have IPv6 compatible socket API. Error can be reproduced by (cross)building for a os that doesn't have these headers. This will abort with a error about incomplete type 'struct in6_addr'. All other uses of IPv6 API in inet_drv.c are conditionalized like in the patch.
2012-02-21erts: Suspend processes waiting for code_ix lockSverker Eriksson
This will prevent blocking entrire schedulers in the rare case when several processes are racing to load/upgrade/delete/purge code.
2012-02-21erts: Fix compiler warning in inet_drvSverker Eriksson
2012-02-21erts: Fix single threaded fallback in new BIF finish_loading_1Sverker Eriksson
Must "start staging" even when we go single threaded.
2012-02-21erts: Fix type bugSverker Eriksson
2012-02-21Break apart erlang:load_module/2 into two separate BIFsBjörn Gustavsson
Introduce two new BIFs, erlang:prepare_loading/2 and erlang:finish_loading/1, and re-implement erlang:load_module/2 in Erlang code. We have two reasons for doing this: * To facilitate suspending a process if another process is already doing code loading. * In the future, we can implement parallel and atomic loading of several modules. Atomic loading works except for modules with on_load handlers. Because of that issue, erlang:finish_loading/2 will currently only accept a list with a single magic binary.
2012-02-21Use magic binaries in erts_prepare_loading() and erts_finish_loading()Björn Gustavsson
