2012-08-14Make get/putenv and erlexec understand UnicodePatrik Nyblom
Putenv and getenv needs to convert to the proper environment strings in Unicode depending on platform and user settings for filename encoding. Also erlexec needs to pass environment strings in an appropriate way for kernel to pick up. All environment strings on the command line, as well as home directory, is now passed in UTF8 on windows and in whatever encoding you have on Unix, kernel tries to convert all parameters and environments from UTF8 before making strings.
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.

Can still not setup -a, but cerl works.
2011-11-17external.c: Remove the option to create over-sized heap binariesBjörn Gustavsson
Since refc binaries are now supported in literal pools, there is no longer any need to allow the creation of over-sized heap binaries.
2011-10-26Use the proper macros in all BIFsBjörn Gustavsson
As a preparation for changing the calling convention for BIFs, make sure that all BIFs use the macros. Also, eliminate all calls from one BIF to another, since that also breaks the calling convention abstraction.
2011-05-10Replace io_list_len() with erts_iolist_size()Björn Gustavsson
The io_list_len() function returns an int, where a negative return value indicates a type error. One problem is that an int only consists of 32 bits in a 64-bit emulator. Changing the return type to Sint will solve that problem, but in the 32-bit emulator, a large iolist and a iolist with a type error will both return a negative number. (Noticed by Jon Meredith.) Another problem is that for iolists whose total size exceed the word size, the result would be truncated, leading to a subsequent buffer overflow and emulator crash. Therefore, introduce the new erts_iolist_size() function which returns a status indication and writes the result size through a passed pointer. If the result size does not fit in a word, return an overflow indication.

New NIF features: Send messages from a NIF, or from thread created by NIF, to any local process (enif_send) Store terms between NIF calls (enif_alloc_env, enif_make_copy) Create binary terms with user defined memory management (enif_make_resource_binary)

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.

2010-03-10Fit 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.
