2011-08-08erts/emulator/Makefile.in: Remove clearmake supportBjörn Gustavsson
2011-08-03Fix binary construction with huge literal sizesBjörn Gustavsson
Constructing binaries using the bit syntax with literals sizes that would not fit in an Uint will either cause an emulator crash or the loading to be aborted. Use the new TAG_o tag introduced in the previous commit to make sure that the attempt to create huge binary literals will generate a system_limit exception at run-time.
2011-08-03beam_load.c: Add overflow check of tag valuesBjörn Gustavsson
The handling of large values for other tags than TAG_i (integer) is buggy. Any tag value equal to or greater than 2^40 (5 bytes) will abort loading. Tag values fitting in 5 bytes will be truncated to 4 bytes values. Those bugs cause real problems because the bs_init2/6 and bs_init_bits/6 instructions unfortunately use TAG_u to encode literal sizes (using TAG_i would have been a better choice, but it is too late to change that now). Any binary size that cannot fit in an Uint should cause a system_limit exception at run-time, but instead the buggy handling will either cause an emulator crash (for values in the range 2^32 to 2^40-1) or abort loading. In this commit, implement overflow checking of tag values as a preparation for fixing the binary construction instructions. If any tag value cannot fit in an Uint (except for TAG_i), change the tag to the special TAG_o overflow tag.
2011-08-03beam_makeops: Add some sanity checksBjörn Gustavsson
We want to make sure that a tag/type name is not defined more than once and that we don't define too many primitive tags. Primitive tags must be named with lowercase letters (or they will be confused with variable names in transformations in the ops.tab file).
2011-08-03Fix construction of <<0:((1 bsl 32)-1)>>Björn Gustavsson
Attempting to construct <<0:((1 bsl 32)-1)>>, the largest bitstring allowed in a 32 bit emulator, would cause an emulator crash because of integer overflow. Fix the problem by using an Uint64 to avoid integer overflow. Do not attempt to handle construction of <<0:((1 bsl 64)-1>> in a 64-bit emulator, because that will certainly cause the emulator to terminate anyway because of insufficient memory.

2011-07-27Fix epmd crash on vxworks caused by faulty argument to selectSverker Eriksson
The first argument g->max_conn to select() in epmd_srv.c seems to be wrong as it excludes the listening socket(s). Instead we keep track of the highest fd seen. However I still don't understand why select() started to fail for vxworks with R14B03 when the feature of more than one listening socket was introduced. The default is still 1 listening socket (num_sockets=1), which would make the first argument to select() unchanged.

2011-07-07Fix a match-spec trace bug that could cause emulator crashSverker Eriksson
A trace matchspec with 'enable_trace' or 'disable_trace' in body could cause an emulator crash if a concurrent process altered the trace setting of the traced function by calling erlang:trace_pattern. The effect was a deallocation of the binary holding the matchspec program while it was running. Fixed by increasing reference count of ms-binary in the cases when 'enable_trace' or 'disable_trace' may cause a system block that may alter the ongoing trace. The paradox here is that db_prog_match() is using erts_smp_block_system() to do 'enable_trace' and 'disable_trace' in a safe (atomic) way. But that also have the (non-atomic) effect that racing thread might block the system and change the trace settings with erlang:trace_pattern.
2011-07-07Fix bug in ets:delete for write_concurrency that could lead to deadlockSverker Eriksson
Relocking in ets_delete_1() and remove_named_tab() was done by unlocking the table without clearing the is_thread_safe flag. A racing thread could then read-lock the table and then incorrectly write-unlock the table as db_unlock() looked at is_thread_safe to determine which kind of lock to unlock. Several fixes: 1. Make db_unlock() use argument 'kind' instead of is_thread_safe to determine lock type. 2. Make relock logic use db_lock() and db_unlock() instead of directly accessing lock primitives. 3. Do ownership transfer earlier in ets_delete_1 to avoid racing owner process to also start deleting the same table.

2011-06-08Replace atom in DRV macro in prim_file with stringStavros Aronis
An experimental version of Dialyzer discovered that the atom that replaced the DRV macro in prim_file ends up in calls to erlang:open_port({spawn, Driver}, Portopts) as the Driver argument. The documentation states that this call requires a string there. This change is also consistent with the one introduced in commit 0f03b1e9d2bef3bc830c31a369261af4c5234727 by Kostis Sagonas.
