2011-08-30Improve performance of upgrade when many processes have old codeSiri Hansen
This commit utilizes the new bif erlang:check_old_code/1 to check if a module has old code in the system or not before running erlang:check_process_code/2. This is to optimize release_handler:install_release (and release_handler:check_install_release). A new test is added which checks that after traversing all processes/modules once and purging all old code, the second run through this part of the code is "sufficiently" much faster. A note is also added in the reference manual for release_handler:install_release about how to go around the efficiency problem of this function.

2011-08-25Add erlang:check_old_code/1Björn Gustavsson
Add erlang:check_old_code/1 to quickly check whether a module has old code. If there is no old code, there is no need to call erlang:check_process_code/2 for all processes, which will save some time if there are many processes.
2011-08-25check_process_code/2: Quickly return 'false' if there is no old codeBjörn Gustavsson
There is no need to suspend the process if the module has no old code. Measurements show that this change will make erlang:check_process_code/2 in an SMP emulator about four times faster if the module has no old code.

2011-08-24Fix message handling in select requestsAhmed Omar
percept_db used to send results in untagged messages, and use a non selective receive to extract them. When percept is used from the shell process, this can confuse other messages with the actual result. Add a tag to the message to be {result, Result}.

2011-08-17Allow @enum when AVP is defined in an inherited dictionary.Anders Svensson
3GPP standards (for one) extend the values allowed for RFC 3588 AVP's of type Enumerated. Previously, extending an AVP was only possible by completely redefining the AVP.
2011-08-17@id required in dictionary files only when @messages is specified.Anders Svensson
@id defines an application identifier and this is used only when sending or receiving messages. A dictionary can define only AVP's however, to be included by other dictionaries using @inherits, in which case it makes no sense to require @id. Note that message definitions are not inherited with @inherits, only AVP's
2011-08-17Fix dialyzer warning on default clause for binary comprehensionIvan Dubrov
Fixed dialyzer warning occuring on binary comprehension of form "<< <<>> || {A, B} <- [{a, b}] >>" caused by default clause inserted by compiler. Since this clause is different from the case of list comprehension, dialyzer fails to suppress that warning.

2011-08-15fix 64-bit issues in the garbage collectionRichard Carlsson
We discovered that if a single Erlang process tried to grow above 32 GB (i.e., more 64-bit words than can be counted by a 32-bit number), the VM failed to find the next larger heap size, even though there were plenty more heap sizes left to pick from and even though we had a lot more memory available on the machine. (Obviously, this is only applicable on 64-bit Erlang.) It turned out to be due to some 'int' variables in the heap resizing parts of erl_gc.c not being properly updated to 'Uint' or 'Sint'. Once that was fixed, I got segfaults instead as soon as the heap got larger than 2^32 words, due to even more 'int' declarations in the same file, but now in the GC code. After fixing this as well, I successfully ran an Erlang node in which a single Erlang process had a heap so large that I'm not at liberty to divulge the exact size, but I think the scientific term is "humongous", and I'm confident that there are no further immediate problems with very very large individual process heaps.
