2014-01-14epmd: Fix -names option on WindowsJohannes Weißl
Since 3aa60cc `epmd -names` does not produce any output on Windows anymore. This patch uses fwrite() instead of write() which adds the necessary carriage returns to the output so that it is suitable for the Windows cmd.exe. A test case is added (fails on Windows without the patch).

2014-01-10erts: Make sure fds 0,1 and 2 are openLukas Larsson
If they are not open a really nasty race where the io pipe in erl_poll got fd 0 and the fd_driver setting fd 0 to blocking could occur. This caused the emulator to hang during shutdown.

2013-12-19improve performance for orddict:from_list/1Steve Vinoski
Improve the performance of orddict:from_list/1 by reimplementing it using the lists module in a way that preserves backward compatibility. The QuickCheck programs linked below were used to verify backward compatibility: * https://gist.github.com/vinoski/3bd216efa421c581174a * https://gist.github.com/vinoski/c6db70e8dc725083843d Both tests, which were run on R16B03, require the original orddict module to be renamed to olddict, and that code:unstick_mod/1 be applied to orddict in order to allow it to be replaced with the revised orddict. The first QuickCheck test first generates a list of pairs of terms, then uses the list to create both an original and revised orddict using from_list/1, then verifies that the results of the operation are the same for both instances. The second QuickCheck test is similar except that it first creates an instance of the original and revised orddicts and then folds over a randomly-generated list of orddict functions, applying each function to each orddict instance and verifying that the results match. The revised orddict:from_list/1 function was also tested to assess performance against the original orddict implementation. The test program used is available here: * https://gist.github.com/vinoski/61772a052f3501e1e128 Since an orddict instance is implemented as a list, the test program creates ordicts of length 1, 10, 100, and 1000 and uses them to assess performance at each length. Performance was measured using timer:tc/3 to time a number of iterations of various tests against the original orddict and against the revised orddict. To test from_list/1, orddicts of lengths 1, 10, 100, and 1000 are created from a list of random pairs with integer keys. For lengths greater than 1, two different tests are performed: one passing a list of pairs in sorted key order, and the other passing a list of pairs in reverse sorted key order. Since orddicts are ordered, these orderings effect worst-case and best-case behavior of the original orddict:from_list/2 implementation respectively. These tests were performed against R16B02 on a Macbook Pro with an Intel Core i7 processor running at 2.7GHz and 16GB of RAM running OS X 10.8.5, and on a Dell system with a 3.4GHz Intel Core i7 and 16GB of RAM running Ubuntu Linux 12.04. The tables below show results for OS X and Linux respectively. Each table lists the name of each test followed by two numbers, each a time in microseconds of the average of 10 runs of the test. The first number is the result for the original orddict, the second for the revised orddict. As the numbers for both platforms show, the revised from_list/1 function is always faster than the original version, in some cases quite a bit faster. Results from OS X: ------------------ from_list length 1: 1.789 0.116 from_list length 10 ordered: 10.082 3.040 from_list length 10 reverse ordered: 4.853 3.604 from_list length 100 ordered: 397.213 20.134 from_list length 100 reverse ordered: 25.473 20.745 from_list length 1000 ordered: 37490.26 251.46 from_list length 1000 reverse ordered: 307.94 215.96 Results from Linux: ------------------- from_list length 1: 0.146 0.025 from_list length 10 ordered: 4.729 0.815 from_list length 10 reverse ordered: 1.687 0.956 from_list length 100 ordered: 144.467 5.896 from_list length 100 reverse ordered: 6.694 5.816 from_list length 1000 ordered: 13755.19 79.413 from_list length 1000 reverse ordered: 91.54 64.308

* siri/master-cuddle-with-tests: [sasl] Fix error printout in release_handler_SUITE to handle unicode path
2013-12-19Eliminate bottlenecks in sys_core_foldBjörn Gustavsson
Compiling programs with very many uses of the "dot notation" for extracting a record element could be very slow. The reason is that each extraction of a record element (R#r.a) would first be transformed to code like this: case R of {r,rec0,_,_} -> rec0; _ -> error({badrecord,r}) end In Core Erlang, each '_' would be become a new variable. The resulting code would be optimized by sys_core_fold, but the optimization process could be very slow. Profiling shows that sub_del_var/2 was the worst bottleneck, and the sub_is_val/2 the second worst bottleneck. In both cases, the culprit is the linear traversal of a very long list (the list of variable substitutions). Fortunately, there already is a gb_set (the scope) which contains all variables that are currently live. If a variable is not known to be live, it is no point in doing the linear operation on the list.

* ta/compiler/asm-core/OTP-11547: Officially support building core files Officially support building assembler files
2013-12-18Officially support building core filesTuncer Ayaz
erlc is wired to treat *.core files as core and build them as compile:file(File, [from_core]), but this is not documented. There's also an udocumented compile:file/2 option called 'from_core'. This has been in place and in use for a long time. Therefore, it should be supported officially. To fix that, make the following changes: * document erlc handling of *.core files * document 'from_core'
2013-12-18Officially support building assembler filesTuncer Ayaz
erlc is wired to treat *.S files as assembler and build them as compile:file(File, [from_asm]), but this is not documented. There's also a documented compile:file/2 option called 'asm' (mapping to 'from_asm'), but the wording discourages its use. All of this has been in place and in use for a long time. Therefore, it should be supported officially. To fix that, make the following changes: * document erlc handling of *.core files * un-document 'asm' and document 'from_asm' instead * deprecate 'asm' While at it, fix a minor typo in the test suite.
