2012-01-11beam_load.c: Don't show unnecessary context in errorsBjörn Gustavsson
For errors that occur after reading the code chunking, saying that the error occurred in the last function in the module and in the instruction int_code_end/0 is just confusing.
2012-01-11beam_load.c: Remove useless call to next_heap_size()Björn Gustavsson
The idea was probably to cause less fragmentation. Even if that would be true, it is irrelevant because the short-lived allocator that is used does not have any problems with fragmentation. In CodeNeed() we will simply double the size of the area used for code instead of using the next heap size.
2012-01-11beam_load.c: apply/2 does not need a special caseBjörn Gustavsson
It is wrongly assumed in the BEAM loader that apply/2 is a BIF and must be treated specially. Also make it clearer in ops.tab that apply/3 is a BIF, but apply/2 is not.

2011-12-20Remove bad assertRickard Green
It is possible also in non-SMP case: 1. The process receives an exit signal and is set in status exiting and inserted into the run queue. 2. The distribution port exits before the process has been selected for execution and cannot remove the link half on the process since it is in status exiting. 3. Process is selected for execution and when removing this link half the distribution channel is gone!

2011-12-07BEAM loader: Fix bug that allowed loading of more than two versionsBjörn Gustavsson
In commit b67d3e5447f4b2bca3ed92f3db84adb3f79f9b16 (which cleaned up handling of error reasons), the test of the return value from beam_make_current_old() in insert_new_code() was not updated, which meant that it never was true and any number of versions of code could be loaded for a module.

2011-12-06erts: Remove truncation of http packet parsing and return error insteadSverker Eriksson
This is a slight modification of previous commit by Steve Vinoski For backward compatibility of old users of decode_packet, I think it's enough to return error instead of keeping the old line truncation behaviour.
2011-12-05honor packet_size for http packet parsing to fix OTP-9389Steve Vinoski
Allow applications to use a packet_size setting on a socket to control acceptable HTTP header line length. This gives them the ability to accept HTTP headers larger than the default settings allow, but also lets them avoid DOS attacks by accepting header lines only up to whatever length they wish to allow. Without this change, if an HTTP request/response line or header arrives on a socket in http, http_bin, httph, or httph_bin parsing mode, and the request/response line or header is too long to fit into a default inet_drv buffer of 1460 bytes, an unexpected error occurs. These problems were described and discussed on erlang-questions in June 2011 in this thread: http://erlang.org/pipermail/erlang-questions/2011-June/059563.html In the original code, no buffer reallocation occurs to enlarge the buffer, even if packet_size or line_length are set in a way that should allow the HTTP data to be parsed properly. The only available workaround was to collect headers and parse them using erlang:decode_packet, but that approach has drawbacks such as having to collect all HTTP header data before it can be handed to decode_packet for correct parsing, and also requiring each and every Erlang web server developer/maintainer to add the workaround to his or her web server. Change the packet parser to honor the packet_size setting for HTTP parsing. If packet_size is set, and an HTTP request/response or header line exceeds the default 1460 byte TCP buffer limit, return an indication to tcp_remain that it should realloc the buffer to enlarge it to packet_size. Also fix the HTTP parsing code to properly honor line_length by truncating any HTTP request/response or header lines that exceed that setting. For backward compatibility, default behavior is unchanged; if an application wants to be able to accept long HTTP header lines, it must set packet_size to an appropriate value. Buffer reallocation occurs only when needed, so the original default buffer size in the code is still the default. Make the line mode parsing honor packet_size as well, for consistency. Add new regression tests to the emulator decode_packet suite and also to the kernel gen_tcp_misc suite. The documentation for packet_size in inet:setopts/2 is already sufficient. Many thanks to Sverker Eriksson for his guidance on how to best fix this bug and also for reviewing a number of patch attempts prior to this one.
