2010-10-07Incorporate Michael Santos patch for cerl and gdb via emacsPatrik Nyblom
Michael Santos supplied a very nice patch that did set the annotation level correctly for gdb when run from cerl in emacs. The patch adds --annotate=3 to the gdb command line, which makes emacs parse the gdb output correctly, making the right source code be loaded in the emacs buffer. While integrating it, I removed my faulty code trying to do the same with hacky elisp commands. Michaels way is the right way to do it. Thanks!

2010-10-06Added win32 large address aware link optionBlaine Whittle
This link option just sets a flag in the binary and doesn't change OS compatibility. This allows the Erlang VM to use up to 3 gigs of address space instead of the default of 2 gigs.
2010-10-06Documentation update to ETS and driversSverker Eriksson
State more clearly that ETS functions will throw badarg if calling process lacks access right. And that driver stop callback should free memory allocted by start.

2010-10-02Fix crash with erlang:system_info({cpu_topology,junk})Paul Guyot
There is a bug in system_info BIF causing a crash if erts_get_cpu_topology_term fails. The fix comes with a non-regression test.

2010-10-01emulator Makefile: Add missing dependencyBjörn Gustavsson
Make sure that an update to erts/emulator/tools/make_tables will force all generated files to be re-generated.
2010-09-30Fix appending to large files (>4GB) on WindowsJuhani Rankimies
Append mode doesn't work for files larger that 4GB on Windows. Caused by incorrect usage of SetFilePointer in win_efile.c. Fix uses OVERLAPPED structure to specify write position (EOF). http://msdn.microsoft.com/en-us/library/aa365747.aspx Opening file in append mode was also considered, but rejected, because it might cause backwards incompatibility by limiting applicable operations on the descriptor. SetFilePointerEx was not used because it would caused more system calls than using OVERLAPPED structure.
2010-09-30Fix a bug in the ERTS_BIF_PREP_TRAPx() macrosBjörn Gustavsson
It seems to work (at least on a little-endian architecture) by sheer luck.
2010-09-30fix 64-bit writes to 32-bit struct field in HiPE runtimeMikael Pettersson
In the HiPE part of the runtime system's Process struct there is a state field which is 32 bits wide even on 64-bit machines. There is a single instruction in the HiPE AMD64 runtime where this field is incorrectly written with a 64-bit store. Luckily the extraneous 32 bits are written as zeros to 4 bytes of tail-padding at the end of the struct, so nothing should have broken because of this. The same bug exists in the HiPE PowerPC64 runtime (in development), but on the big-endian PPC64 the effect is to write the actual value to the tail-padding and zero to the struct field, which potentially breaks TRAPs from BIFs (depending on BIF arities and how many parameter registers the runtime has been configured to use). Thanks to Paul Guyot for noticing the oversized write on AMD64.
2010-09-29Add corrected support for Solaris PTYs to run_erlRyan Tilder
Two related but slightly separate issues: run_erl doesn't support Solaris's /dev/ptmx device and run_erl didn't load the necessary STREAMS modules so that to_erl can provide terminal echo of keyboard input. This patch adds ifdef'd support for Solaris and derivatives to open /dev/ptmx directly since adding the C99 defines to CFLAGS breaks all kinds of other things in the build. It also adds ifdef'd ioctl calls to load the necessary STREAMS modules to permit termios to work.
2010-09-29Fix a typo that leads to syntax errors with DEBUG defined in run_erlRyan Tilder
While attempting to debug odd terminal echo issues on Solaris, I noticed that run_erl.c will fail to compile due to a typo causing a syntax error.
2010-09-24Remove stray use of _VOID_Björn Gustavsson
In a70159b33f20a26b2674d7cf777617c5f0261a5c, the _VOID_ macro was eliminated, but one use of it inside an "#ifdef DEBUG" was forgotten.

Use mutex instead of rwlock since the read lock is more or less unused and it can be quite contended.

2010-09-09Make gen_tcp:recv/2 consistent with ssl:recv/2Björn Gustavsson
When the HTTP packet mode has been enabled for a socket, the ssl and gen_tcp modules have different error indications when there is an error while parsing the HTTP header: ssl:recv(SSLSocket, 0) -> {ok, {http_error, _Str}} gen_tcp:recv(Socket, 0) -> {error, {http_error, _Str}} We have decided to change gen_tcp:recv/2 to behave the same way as ssl:recv/2. That means that there will be always be an ok tuple if data could be succefully read from the socket, and an error tuple if there was a read error at the socket level.
2010-09-08Fix deadlock in reader optimized rwlock implementationRickard Green
A bug causing a deadlock in the reader optimized rwlock implementation has been fixed. This bug appeared in commit 59ee2a593090e7d53c97ceba63cbd300d1b9657e, i.e., it has not been seen in any released versions.

Spin wait on most ethread rwlocks used by the runtime system was unintentionally disabled during development. Spin wait has now been enabled again. This bug appeared in commit 59ee2a593090e7d53c97ceba63cbd300d1b9657e, i.e., it has not been seen in any released versions.
