2010-05-21Merge branch 'sv/format_status_error_info' into devErlang/OTP
* sv/format_status_error_info: Add support for the format_status callback to gen_event Extend format_status for gen_server/gen_fsm termination error logging OTP-8630 sv/format_status_error_info When a gen_server, gen_fsm process, or gen_event terminates abnormally, sometimes the text representation of the process state can occupy many lines of the error log, depending on the definition of the state term. A mechanism to trim out parts of the state from the log has been added (using a format_status/2 callback). See the documentation.

2010-05-20Add file:advise/4 - a wrapper to the POSIX syscall posix_fadviseFilipe David Manana
Useful for informing the Operating System about the access pattern for a file's data, so that it can adapt the caching strategy to maximize disk IO performance.
2010-05-20Add file:datasync/1 for syncing file contents onlyFilipe David Manana
file:datasync/1 invokes the POSIX system call "int fdatasync(int fd)". This system call is similar to "fsync" but, unlike fsync, it does not update the metadata associated with the file (like the access time for example). It's used by many DBMSs (MySQL and SQLite of example) to increase disk IO performance, as it avoids disk seeks and disk write operations compared to fsync. More details on it at: http://linux.die.net/man/2/fdatasync An example, from the MySQL source: http://bazaar.launchpad.net/~mysql/mysql-server/mysql-5.1-telco-6.1/annotate/head%3A/mysys/my_sync.c#L61 This new function just calls fsync on systems not implementing fdatasync.
2010-05-20v3_life: Remove clause that cannot match in match_fail/3Björn Gustavsson
The clause that attempts to match a #k_literal{} where the value is an atom cannot possibly match, since single atoms are always encoded as #k_atom{}.
2010-05-20v3_life tests: Cover exception handling code in v3_life:function/1Björn Gustavsson
2010-05-20beam_type: Remove redundant clauseBjörn Gustavsson
The clause does not server any useful purpose, since it does the same as the default clause at the end.
2010-05-20v3_core tests: Cover make_bool_switch_guard/5Björn Gustavsson
2010-05-20v3_core tests: Cover handling of pattern aliasesBjörn Gustavsson
2010-05-20v3_core: Remove a clause in is_simple/1 that cannot matchBjörn Gustavsson
The is_simple/1 function does not need to handle #c_binary{}, since it will never be called with a #c_binary{} argument.
2010-05-20v3_core: Remove unused support for generating compilation errorsBjörn Gustavsson
The state record #core{} has a "es" field that can be used for causing a compilation error. Since incorrect programs have been rejected much earlier by erl_lint, no errors were actually stored in the "es" fields. Therefore, get rid of the "es" field and the support for generating a compilation error in the v3_core module.
2010-05-20Remove stray support for the put_literal/2 instructionBjörn Gustavsson
put_literal/2 was an experimental instruction added in R11 to support literals, but before the R12 release support for literals was implemented for all instruction, making the put_literal/2 instruction redundant. Although the beam_disasm module supports dissambley of instructions in older releases, there is no reason to have it support experimental instructions.
2010-05-20Remove stray support for the bs_bits_to_bytes2/2 instructionBjörn Gustavsson
bs_bits_to_bytes2/2 was an experimental instruction added in R11, but was removed in R12. Although the beam_disasm and beam_validator modules do support instructions in older releases, there is no reason to have them support experimental instructions.
2010-05-20Remove the bs_bits_to_bytes/3 instructionBjörn Gustavsson
The last compiler to generate code that uses the bs_bits_to_bytes/3 instruction was the R11 compiler. Since we don't support loading R11 *.beam files in R14, removing the remaining support for the instruction.
2010-05-20Cover handling of 'math' BIFsBjörn Gustavsson
Extend float_SUITE to cover the handling of all BIFs in the 'math' module. This change will increase test coverage of erl_bifs and erl_type.
2010-05-20beam_bool: Remove a clause in live_regs/1 that cannot matchBjörn Gustavsson
live_regs/1 folds over a list of tuples, so a clause matching an element being an empty list can never match. If the list for some unfathomable reason would contain an empty list, there will be an internal compiler error and no *.beam file will be created. Thus this change is safe.
2010-05-20beam_bool: Cover handling of bs_context_to_binary in initialized_regs/2Björn Gustavsson
Add a test case (derived from dets_v9:scan_skip/8), to cover the clause in initialized_regs/2 that handles bs_context_to_binary.
2010-05-20beam_bool: Remove a clause in initialized_regs/2 that cannot matchBjörn Gustavsson
When scanning a reversed instruction sequence for a function, it is impossible to reach the end of the list, because each function must have a fun_info/4 instruction followed by a label/1 instruction at the beginning, and there is a clause that will handle those instructions. If for some unfathomable reason the end of the list would be reached, with this change there will be an internal compiler error and no *.beam file will be created. Thus this change is safe.
2010-05-20beam_block: Remove a clause that will never be executedBjörn Gustavsson
Since the introduction of literals in R12B, empty tuples are literals. Thus the put_tuple/2 instruction is always followed by at least one put/1 instruction. Therefore the alloc_may_pass/1 function in beam_block no longer needs a clause for for "put_tuple", because the clause for "put" will always be reached first (since the instruction stream is scanned in reverse execution order). Note that if the compiler would generate a "put_tuple 0 Dst" instruction for some unfathomable reason, we should still be because the run-time system will now refuse to load a module containing such an instruction.
2010-05-20compile: Remove code that is only executed on SolarisBjörn Gustavsson
On Solaris only, the 'time' option would include the process size for the Erlang virtual machine in its output. Since few compiler developers use Solaris nowadays, remove the code.
2010-05-20Do not cover-analyze core_scanBjörn Gustavsson
Compiling from *.core files is not a supported feature, and writing test cases to improve the coverage of core_scan will not help us to find more bugs in the compiler.
2010-05-20core_SUITE_data: Don't ignore *.core files in this directoryBjörn Gustavsson
