* maint: erts: Add max alignment posix_memalign configure check
2013-11-01erts: Add max alignment posix_memalign configure checkLukas Larsson
On some OSs posix_memalign exists, but it does not allow for alignment greater than the current page size. So we have to do a runtime check for alignment size and also add cross compile options.

2013-09-25Implement platform specific aligned sys_alloc and use when supportedRickard Green
erts_sys_aligned_alloc() is currently implemented using posix_memalign if it exist, or using _aligned_malloc on Windows. If erts_sys_aligned_alloc() exist allocators will create sys_alloc carriers similar to how this was done pre-R16.

2013-05-28add support for hipe on Raspberry Pi (armv6l)Klaus Alfert
To enable hipe on a Raspberry Pi, configure has to detect the ARM processor correctly. On a Pi, uname detects the CPU as armv6l. Other CPU variants are already detected with ARCH=arm, so does now the armv6l of the Raspberry Pi.

* Default to 'no' for finding a working fallocate
2013-01-09Add file:allocate/3 operationFilipe David Manana
This operation allows pre-allocation of space for files. It succeeds only on systems that support such operation. The POSIX standard defines the optional system call posix_fallocate() to implement this feature. However, some systems implement more specific functions to accomplish the same operation. On Linux, if the more specific function fallocate() is implemented, it is used instead of posix_fallocate(), falling back to posix_fallocate() if the fallocate() call failed (it's only supported for the ext4, ocfs2, xfs and btrfs file systems at the moment). On Mac OS X it uses the specific fcntl() operation F_PREALLOCATE, falling back to posix_fallocate() if it's available (at the moment Mac OS X doesn't provide posix_fallocate()). On any other UNIX system, it uses posix_fallocate() if it's available. Any other system not providing this system call or any function to pre-allocate space for files, this operation always fails with the ENOTSUP POSIX error.

2012-08-16Add checks for in6addr_any and in6addr_loopbackTomas Abrahamsson
These variables are normally declared by <netinet/in.h>, but for instance not on Windows 7, SDK 7.1. Work around that by using IN6ADDR_ANY_INIT and IN6ADDR_LOOPBACK_INIT if present, fallback to using :: and ::1.
2012-08-01Fix support for leap seconds-aware timezonesPiotr Sikora
erlang:universaltime_to_localtime is leap seconds-aware (since 2008), however erlang:localtime_to_universaltime is not, which gives surprising results on systems configured with leap seconds-aware timezones: 1> erlang:universaltime_to_localtime({{2012,1,1},{0,0,0}}). {{2012,1,1},{0,0,0}} 2> erlang:localtime_to_universaltime({{2012,1,1},{0,0,0}}). {{2012,1,1},{0,0,24}} and completely breaks calendar:local_time_to_universal_time_dst: 3> calendar:local_time_to_universal_time_dst({{2011,1,1},{0,0,0}}).

2012-05-10Remove stale code for hybrid heap and incremental GCBjörn Gustavsson
The hybrid heap emulator was last working in the non-SMP R11B run-time system. When the constant pools were introduced in R12B, the hybrid heap emulator was not updated to handle them. At this point, the harm from reduced readability of the code is greater than any potential usefulness of keeping the code.
2012-03-23Unbreak floating point on middle-endian machines.Mike Sperber
On some ARMs (and maybe other platforms), doubles are stored with the the two 32-bit words reversed with respect to more common architectures. The symptom is this: > io_lib:write(1.0). "0.000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000005299808824" Detect that and account for it when decoding floats.

2012-03-22Add DTrace support for OS X, Solaris, and Linux (via SystemTap), 1/4Scott Lystig Fritchie
Since it's been quite a while since I've written C code, *and* I haven't done any significant hacking on the VM itself in years, it's quite likely that I haven't done things in 100% proper style. Or my co-collaborators Dustin Sallings (CouchBase) or Michal Ptaszek (Erlang Solutions). My intent for this patch is to start discussion and review of DTrace support for consideration for the R15 release. For additional background on the motivation for this work, please see the slides for the presentation at the Erlang User Conference 2011 in Stockholm: https://www.erlang-factory.com/upload/presentations/462/euc2011-draft2.pdf Changes relative to dtrace-review2 branch: * Fix errors in OTP test suite 'kernel' file_SUITE * Fix errors in OTP test suite 'kernel' prim_file_SUITE * Fix bad pointer bug in efile_drv.c flush_write() * Move the DTrace material from the top of `README.md` into a new file, `README.dtrace.md` Changes since last push to GitHub (relative to commit 5828a4fb28, which was the former `dtrace-review1` branch): * Rebased onto 14 Nov 2011's "master" branch * Recent changes to the async task queuing mechanism means that the async worker queue length is not available. A bogus value of -1 is hard-coded until there's a good way to peek into the new queue structure and find the queue length. * Small fixes based on review comments by Mikael Pettersson, Andrew Thompson, and Andreas Schultz. Add autoconf support: use "./configure --enable-dtrace" on all supported platforms: * OS X Snow Leopard or later * Solaris 10 or OpenSolaris * Linux, via SystemTap's DTrace compatibility packages * FreeBSD 9.0RC1. FreeBSD 8 and earlier do not have support for USDT, DTrace's User-land Statically Defined Tracing. See the file `erts/emulator/beam/erlang_dtrace.d` for the definition of all DTrace probes in the virtual machine so far. Example D scripts can be found in `lib/dtrace/examples`. Note that if you see the error message `{name of probe} does not match any probes`, then there is no Erlang VM process + DTrace probes running. To fix, start a DTrace-enabled VM or remove `-q` from the `dtrace` command line. The `lib/dtrace` directory contains a small code-only OTP application that contains code that allows Erlang code to trigger a DTrace probe. Dynamic creation & deletion of DTrace probes is not currently supported, so the `dtrace:p()` function is hacked to allow a variable number of arguments (up to four integers and up to four strings) to be used. See the comments at the top of `lib/dtrace/src/dtrace.c` for more detail. One feature that may be controversial is the notion I've introduced of a special process dictionary key that can be used by Erlang code to tag I/O operations for an application-specific purpose. Right now, that tag's name is `dtrace_utag`. The dictionary keys used by `sys` and other modules start with a dollar sign. Perhaps there is some convention (but not a dollar sign?) that this tag should use? The purpose of the process dictionary key is to allow the tag to be included in trace messages, e.g. for file I/O, without changing the API of the `file.erl` module's functions. For example, here's a use of the tag when calling the `file:rename/2` function: (bar@sbb2)1> put(dtrace_utag, "GGOOOAAALL!!!!!"). undefined (bar@sbb2)2> dtrace:init(). ok %% Now start both the `user-probe.d` and `efile_drv.d` D scripts %% found in the `lib/dtrace/examples` directory. (bar@sbb2)3> dtrace:p(7, 8, 9, "one", "four"). true %% The output from the `user-probe.d` script: <0.40.0> GGOOOAAALL!!!!! 7 8 9 0 'one' 'four' '' '' (bar@sbb2)4> file:rename("old-name", "new-name"). {error,enoent} %% The output from the `efile_drv.d` script: async I/O pool port #Port<0.59> queue len 1 async I/O pool port #Port<0.59> queue len 0 efile_drv enter tag={1,110} user tag GGOOOAAALL!!!!! | RENAME (12) | args: old-name new-name , 0 0 (port #Port<0.59>) async I/O worker tag={1,110} | RENAME (12) | efile_drv-int_entry async I/O worker tag={1,110} | RENAME (12) | efile_drv-int_return efile_drv return tag={1,110} user tag GGOOOAAALL!!!!! | RENAME (12) | errno 2 I'm not exactly happy with this choice of tagging, namely using `put(dtrace_utag, Tag::list())`. But this is an experiment, so we'll see how it goes. I can't imagine changing the API for all file.erl functions in order pass the tag explicitly. Some modules have some extensive (ab)use of the C preprocessor to reduce the amount of #ifdefs that clutter the code. In several places, I have not #ifdef'ed automatic variables because of clutter. For the same reason, there are a handful of cases where I added DTrace-related members to a struct definition without an #ifdef. I feel that the result is easier to read than earlier drafts where I did use many more `https://github.com/slfritchie/otp/tree/dtrace-experiment+michal2` if you're curious.) I expect there may be some debate about whether the bloat of the affected structs is worthwhile. I erred on adding stuff to structs, especially in the efile_drv.c driver, not having a full grasp on what was thread-safe and what was not ... so I erred on the side of caution. The efile_drv.c has a work-around for a crazy GCC optimization bug. Thank goodness for Google, I dunno how I would've found a work-around for this silly thing. Many thanks to Trond Norbye for writing clearly about the problem in a membase Git repo commit message. /* * A note on probe naming: if "__" appears in a provider probe * definition, then two things happen during compilation: * * 1. The "__" will turn into a hypen, "-", for the probe name. * 2. The "__" will turn into a single underscore, "_", for the * macro names and function definitions that the compiler and * C developers will see. * * We'll try to use the following naming convention. We're a bit * limited because, as a USDT probe, we can only specify the 4th part * of the probe name, e.g. erlang*:::mumble. The 2nd part of the * probe name is always going to be "beam" or "beam.smp", and the 3rd * part of the probe name will always be the name of the function * that's calling the probe. * * So, all probes will be have names defined in this file using the * convention category__name or category__sub_category__name. This * will translate to probe names of category-name or * category-sub_category-name. * * Each of "category", "sub_category", and "name" may have underscores * but may not have hyphens. */ Add tentative support for sequential tracing sending, queueing, and receiving a message. I don't believe I've fully covered all the major places where it would be useful to have the sequential trace token info in a probe -- guidance from the OTP team would be helpful, if there's time to do that kind of review. Add global variable `erts_this_node_sysname`.
