* sf/erl_match-longlong: erl_interface: Allow erl_match() to match ERL_LONGLONG and ERL_U_LONGLONG terms OTP-8400 Allow erl_match() to match ERL_LONGLONG and ERL_U_LONGLONG terms (Thanks to Scott Lystig Fritchie).
2010-02-02Add option to compress data when copying tables between Mnesia nodesIgor Ribeiro Sucupira
Optionally using data compression for copying Mnesia tables allows the system to be tuned to eliminate network bottlenecks from deployments where enough CPU is available to use zlib. With this patch, running erl -mnesia send_compressed <level> will enable compression for sending tables between nodes. The compression level can be any integer in [0, 9], with 0 (the default) meaning no compression (exactly the previous behaviour) and 9 being the highest compression level. To set any non-zero compression level at the sender, both nodes must have the updated Mnesia modules (the receiver will work according to the sender's configuration).

New section added on Macros Overloading
2010-02-01epp: change rules to choose the right version of a macroChristopher Faulet
Now, when we have only the constant definition of a macro (without arguments), we always use it. In all other cases, we try to find the exact matching definition. We throw an error if we don't find it.
2010-02-01epp: Add support of macros overloadingChristopher Faulet
This feature simplifies the definition of macros by avoiding to have a different name for each version (with different arities) of the same macros. New rules: - can have multiple definitions of the same macro with different arities - cannot overload macro with the same arity - the overloading of predefined macros (?MODULE, ?LINE, ...) is forbidden - the directive '-undef' removes all definitions of a macro
2010-02-01epp: fix bug in the function scan_undefChristopher Faulet
The dict St#epp.uses that helps to find circular macros was not correctly updated.

2010-01-30compiler: make ignore_native_errors also handle internal hipe errorsBjörn Gustavsson
We must also catch exits, not only errors, since the hipe compilers does an exit/1 if an internal error is found.
2010-01-30re tests: disable native-code compilation for huge modulesBjörn Gustavsson
Two generated modules contains too big functions for the native-code compiler to handle (even the BEAM compiler struggles when compiling them).
2010-01-30Teach the compiler the no_native optionBjörn Gustavsson
Implement the 'no_native' option to disable native-code compilation. If given in a module like this: -compile(no_native). it will override a 'native' option given on the command line.

* ta/ensure_dir_eexist: filelib_SUITE: strenghten tests of filelib:ensure_dir/1 Don't return a false {error,eexist} in filelib:ensure_dir/1 OTP-8389 Because of a race condition, using filelib:ensure_dir/1 from multiple processes to create the same path or parts of the same directory structure, filelib:ensure_dir/1 could return a meaningless {error,eexist}. That race condition has been eliminated, and {error,eexist} will now be returned only if there exists a regular file, device file, or some other non-directory file with the same name. (Thanks to Tuncer Ayaz.)

* mp/hipe-smp-fixes: work around hipe_mfa_info_table lock omission fix hipe loader SMP non-atomicity error OTP-8397 The loading of native code was not properly atomic in the SMP emulator, which could cause crashes. Also a per-MFA information table for the native code has now been protected with a lock since it turns that it could be accessed concurrently in the SMP emulator. (Thanks to Mikael Pettersson.)

Don't change any guard tests in the id_transform_SUITE module, because it intentionally use the old guard tests to test that id_transform can handle them.
2010-01-29Test suites: fix creation of EmakefilesBjörn Gustavsson
The Emakefiles in some test suite directories are only appended to, never created from scratch, which can cause problems especially when swithching branches in a git repository.

2010-01-27work around hipe_mfa_info_table lock omissionMikael Pettersson
HiPE maintains per-MFA information such as native code entry point in a table. This table was thought to be read-only at runtime, except when the loader populates it, so it employed no locking. That turned out to be incorrect: if there is an apply of a previously unseen MFA, a native code stub for that MFA is created and recorded in the table, causing it to grow. Work around this for now by slapping a mutex around accesses to that table. Signed-off-by: Mikael Pettersson <[email protected]>
2010-01-27fix hipe loader SMP non-atomicity errorMikael Pettersson
Loading native code is a multi-step operation that needs to be atomic, but the HiPE loader failed to ensure that. This caused corruption of runtime system structure in some cases. Fix by blocking multi_scheduling around main loader entry points. Signed-off-by: Mikael Pettersson <[email protected]>

Most code, testcases and error isolation done by Rory Byrne.

2010-01-27Fix re:replace/4 to handle unicode charlist Replacement argumentRory Byrne
A bug in re:replace/4 causes a badarg exception to be thrown when the Replacement argument is a charlist containing non-ascii codepoints. The problem is that the code incorrectly assumes that the Replacement text is iodata() and calls iolist_to_binary/1 on it. This patch fixes it to obey the 'unicode' option and handle charlist() Replacement arguments correctly.

2010-01-27Fix re:replace/4 to handle binary unicode output when nothing replacedRory Byrne
A bug with re:replace/4 causes an exception when: (a) it's given a unicode charlist as input; (b) it's set to {return,binary}; and (c) it finds nothing to replace. The problem is: when re:replace/4 does not find anything to replace in its Subject input, it calls iolist_to_binary on this data. This fails if the original input is a charlist with non-ascii codepoints.
2010-01-27OTP-8387 Explicit top directories in archive files are now optional.Håkan Mattsson
For example, if an archive (app-vsn.ez) just contains an app-vsn/ebin/mod.beam file, the file info for the app-vsn and app-vsn/ebin directories are faked using the file info from the archive file as origin. The virtual direcories can also be listed. For short, the top directories are virtual if they does not exist.

Test that filelib:ensure_dir/1 returns {error,eexist} if there already exists a regular file with the name as a directory that should be created. While at it, slightly strenghten the otp_5960/1 test case by repeating each call to filelib:ensure_dir/1.
2010-01-23Remove mutex lock around sys_gettimeofday() in os:timestamp/0Tuncer Ayaz
In the erlang-questions thread "os:timestamp() uses mutex lock" Jonas Falkevik questioned the need for a mutex lock in os:timestamp/0. The mutex lock *is* needed in erlang:now() to guarantee the uniqueness of the returned time, but serves no useful purpose in os:timestamp(). Signed-off-by: Tuncer Ayaz <[email protected]>
