2010-04-30emulator: Eliminate #ifdef for sys_tty_reset()Björn Gustavsson
In the erts/emulator/beam sources #ifdef SOME_OPERATING_SYSTEM should be avoided. Instead, call a function implemented in sys/OPERATING_SYSTEM/sys.c.

2010-04-20re: Fix non-termination for a certain regular expressionMichael Santos
The following code never terminates: fail() -> Str = "http:/www.flickr.com/slideShow/index.gne?group_id=&user_id=69845378@N0", EMail_regex = "[a-z0-9!#$%&'*+/=?^_`{|}~-]+" ++ "(?:\.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*" ++ "@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+" ++ "(?:[a-zA-Z]{2}|com|org|net|gov|mil" ++ "|biz|info|mobi|name|aero|jobs|museum)", io:format("about to run...~n"), Ret = re:run(Str, EMail_regex), io:format("Ret is ~p~n", [Ret]). Fix it by having pcre_exec remember match_call_count between restarts. Reported-by: Gordon Guthrie Acked-by: Patrik Nyblom

2010-04-14MacOS X: Boost default stack sizeBjörn Gustavsson
The default stack size on MacOS X for the SMP emulator is too small to support all uses of pcre. For example, the following expression N = 819, re:compile([lists:duplicate(N, $(), lists:duplicate(N, $))]). will cause a stack overflow. By bisection of different values for the +sss option, I found that 166 is the smallest value that avoids the crash. Round that up to 256 to give a nice, round power of 2 and a resonable safety margin. Use that value as a default stack size on MacOS X only.
2010-04-14Fix check for compile workspace overflowMichael Santos
Patch from: http://vcs.pcre.org/viewvc/code/trunk/pcre_compile.c?r1=504&r2=505&view=patch Test case: N = 819, re:compile([lists:duplicate(N, $(), lists:duplicate(N, $))]). Compiling large regular expressions could overflow the workspace buffer. Modify the test to check for a value smaller than the buffer size.

The following program is supposed to cause an exception at run-time: foo() -> Sum1 = Sum2 = N = 2, pSum - (Sum1*(Sum2/N)). but the loader fails to load because it contains the following instruction: fconv {atom,pSum} {fr,2} Fix the loader so that it can handle fconv instructions where the first operand is a non-numeric literal.

2010-03-31OTP-8484 Fix minor cross compilation issuesRickard Green
The use of mmap() was unnecessarily disabled when cross compiling. The configure arguments --with-ssl, and --with-odbc refused to accept libraries outside of $erl_xcomp_sysroot when cross compiling for no good reason. The configure argument --with-odbc didn't handle the value yes correct. The configure arguments --with-odbc, and --without-odbc have also been added to the configure help. (Thanks to Steve Vinoski for reporting these issues)

* se/decode_packet: Fix erlang:decode_packet(httph_bin,..) to not return faulty header strings OTP-8548 se/decode_packet erlang:decode_packet(httph_bin,..) could return corrupt header strings or even crash the VM. This has been fixed. It only happened on 32-bit VM if the header name was unknown and between 16 and 20 characters long. Sockets with simular packet option did not suffer from this bug.
2010-03-29Fix erlang:decode_packet(httph_bin,..) to not return faulty header stringsSverker Eriksson
Unrecognized Http header names was sometimes returned as corrupt sub-binaries pointing to a stack allocated buffer. This only happened on 32-bit VM if the header name was between 16 and 20 characters long. It could in some cases lead to segmentation fault. The solution was to avoid creating sub-binary if the returned string was not part of the original binary.
2010-03-26Fix spelling: "loose" is not a verbMagnus Henoch
"Lose" means not "not win", but "loose" means "not tight". Change "loose" to "lose" where appropriate.

2010-03-17Merge branch 'hawk/escript-add-create-and-extract' into devErlang/OTP
* hawk/escript-add-create-and-extract: Add type info for record fields Remove the undocumented function escript:foldl/3 Make reltool independent of the function escript:foldl/3 Add functions to create and extract escripts Add function zip:foldl/3 to iterate over zip archives OTP-8521 hawk/escript-add-create-and-extract Added function zip:foldl/3 to iterate over zip archives. Added functions to create and extract escripts. See escript:create/2 and escript:extract/2. The undocumented function escript:foldl/3 has been removed. The same functionality can be achieved with the more flexible functions escript:extract/2 and zip:foldl/3. Record fields has been annotated with type info. Source files as been adapted to fit within 80 chars and trailing whitespace hasd been removed.
2010-03-16Add functions to create and extract escriptsHåkan Mattsson
Both reltool and rebar needs to parse escripts. They are currently using an undocumented function called escript:foldl/3. It folds a function over all files in the body of an escript. If the body contains source code the function compiles it and the gives debug compiled beam code to the fold fun. If the body is an archive the fun is applied for all files in the archive. Instead of making the undocumented function public, the new functions escript:create/2 and escript:extract/2 has been introduced. Together with the new zip:foldl/3 function they have the same functionality as escript:foldl/3 in a more flexible and generic way. escript:foldl/3 should be removed as soon as reltool and rebar has been adopted to use the new functions. The simplest way for reltool and rebar to do this is to just copy the code from escript_SUITE:escript_foldl/3, which happens to provide a future compatible implementation of an emulated escript:foldl/3 function. I was quite hesitant when I introduced the compile_source option. It feels that it does not belong there but the alternative felt worse. The rationale for the compile_source option is that it is a bit cumbersome to compile the source code, as the source in most cases is partial. In order to do compile the source you need to know about some internals in escript. Without compile_source I think that these internals should be documented. Further you need to duplicate parts of the code. Without the compile_source option you need to first parse the source to forms, using an undocumented function in epp with an extended format of predefined macros which also is undocumented. Then you need to investigate the forms to see if you need to add an export form for main. When that is done you can run the rest of the compiler passes as usual. It is not so much code (60 lines or so) to write, but I do not want to urge people to write it. I actually wrote the code (see escript_SUITE:escript_foldl/3) before I decided to introduce the compile_source option.
2010-03-16Add function zip:foldl/3 to iterate over zip archivesHåkan Mattsson
This is the public interface of prim_zip:open/3, which has been used in earlier releases by both erl_prim_loader and escript. The new function can be used as a replacement for the undocumented function escript:foldl/3 that is likely to be removed without further notice. The error handling of prim_zip:open/3 (and prim_zip:foldl/3) has been improved in order to better suite a public interface. For example it could happen that a file or a zlib port could be left open in some errors cases. The documentation of the FileSpec parameter to zip:create/3 has been updated to show that file info can be explicitly specified. A FileSpec may contain {Filename, binary(), #file_info{}} elements. The function zip:create/3 was already prepared to partly support this, but now after a few minor fixes it is fully supported.
2010-03-16Correct grammatical problems in conjunction with 'its'Matthias Lang
2010-03-16Change all incorrect occurrences of it's to itsMatthias Lang
The documentation (*.xml) in the otp tree has a common grammatical problem, "it's" and "its" are often interchanged. That is annoying for some readers. This commit consists entirely of "it's" -> "its" changes. I went through every .xml file in the tree. If there are any remaining bugs of this type, it's because I missed them, not because I didn't look.
2010-03-12Teach testcase in driver_suite the new prototype for driver_asyncPatrik Nyblom
The testcase core dunmped. Also made sure the key could actually store long integers in driver_async (which is more of a cosmetic change).
2010-03-10Adopt the new (R13B04) Nif functionality to the halfword codebasePatrik Nyblom
Change erl_int_sizes_config to include HALFWORD_HEAP_EMULATOR, which make it possible for the NIFs to figure out the term size.
2010-03-10Support monitoring and demonitoring from driver threadsPatrik Nyblom
The driver in the wx application does monitoring (and demonitoring) from non-scheduler threads. In the non-half-word emulators, data will be modified without the protection of a lock (which is potentially bad), but the half-word emulator will crash in that situation. While at it, also correct an old bug which make assertions fail in the Kernel test suite.
2010-03-10Fix further test-suite problemsPatrik Nyblom
Fix safe_mul in the loader, which caused failures in the bit syntax test cases. Fix yet another Uint in erl_alloc.h (ERTS_CACHE_LINE_SIZE) causing segmentation fault when we have many schedulers (why only in that situation?). Clean up erl_mseg (remove old code for the Linux 32-bit mmap flag). While at it, also remove compilation warnings.
2010-03-10Correct the VM to work for more test suitesPatrik Nyblom
The following test suites now work: send_term_SUITE trace_nif_SUITE binary_SUITE match_spec_SUITE node_container_SUITE beam_literals_SUITE Also add a testcases for system_info({wordsize,internal|external}).
2010-03-10Teach {wordsize,internal|external} to system_info/1Patrik Nyblom
Some test suites need to differentiate between 32-bit terms and 32-bit pointers. While at it, remove some more warnings in process.c for SMP and debug.
2010-03-10Make tracing and distribution workPatrik Nyblom
Rewrite trace code and external coding. Also slightly correct the interface to the match-spec engine to make tracing work. That will make the test suites runnable.
2010-03-10Turn on instruction packing in the loader and virtual machinePatrik Nyblom
2010-03-10Add the BeamInstr data type for loaded BEAM codePatrik Nyblom
For cleanliness, use BeamInstr instead of the UWord data type to any machine-sized words that are used for BEAM instructions. Only use UWord for untyped words in general.
2010-03-10Fix the BEAM dissambler for the half-word emulatorPatrik Nyblom
2010-03-10Store pointers to heap data in 32-bit wordsPatrik Nyblom
Store Erlang terms in 32-bit entities on the heap, expanding the pointers to 64-bit when needed. This works because all terms are stored on addresses in the 32-bit address range (the 32 most significant bits of pointers to term data are always 0). Introduce a new datatype called UWord (along with its companion SWord), which is an integer having the exact same size as the machine word (a void *), but might be larger than Eterm/Uint. Store code as machine words, as the instructions are pointers to executable code which might reside outside the 32-bit address range. Continuation pointers are stored on the 32-bit stack and hence must point to addresses in the low range, which means that loaded beam code much be placed in the low 32-bit address range (but, as said earlier, the instructions themselves are full words). No Erlang term data can be stored on C stacks (enforced by an earlier commit). This version gives a prompt, but test cases still fail (and dump core). The loader (and emulator loop) has instruction packing disabled. The main issues has been in rewriting loader and actual virtual machine. Subsystems (like distribution) does not work yet.
2010-03-10Add a custom mmap wrapper to force heaps into the lower address rangePatrik Nyblom
The free list is still rudimentary for the mmap wrapper and a better implementation will be needed for production quality.
2010-03-10Fit all heap data into the 32-bit address rangePatrik Nyblom
This is the first step in the implementation of the half-word emulator, a 64-bit emulator where all pointers to heap data will be stored in 32-bit words. Code specific for this emulator variant is conditionally compiled when the HALFWORD_HEAP define has a non-zero value. First force all pointers to heap data to fall into a single 32-bit range, but still store them in 64-bit words. Temporary term data stored on C stack is moved into scheduler specific storage (allocated as heaps) and macros are added to make this happen only in emulators where this is needed. For a vanilla VM the temporary terms are still stored on the C stack.
2010-03-10cerl: Work around missing source frame in when running gdb in emacsPatrik Nyblom
This problems occurs in some recent versions of Emacs.
2010-03-10OTP-8475 status lock needed when looking up ioq from async threadsRickard Green
Driver threads, such as async threads, using <seealso marker="erl_driver#ErlDrvPDL">port data locks</seealso> peeked at the port status field without proper locking when looking up the driver queue.
2010-03-10OTP-8487 unregister/1 on a port can cause the non-smp runtime to crashRickard Green
A call to the BIF unregister(RegName) when a port had the name RegName registered in the runtime system without SMP support caused a runtime system crash. (Thanks to Per Hedeland for the bugfix and test case.)
