* blt/gen_server-typo/OTP-11398: Change 'recive' to 'receive' in gen_server.erl
2013-10-12Change 'recive' to 'receive' in gen_server.erlBrian L. Troutwine
A small spelling correction merely; no functionality change.

files as delimiters. While working on a tool that processes Erlang code and testing it against this repo, I found out about those little sneaky 0xff. I thought it may be of help to other people build such tools to remove non-conforming-to-standard characters.
2013-08-27Fix variable usage tracking in some record errorsAnthony Ramine
When reporting a field redefinition in a record, erl_lint can forget about some old unused variables. f() -> X = 1, #r{a=foo,a=bar,a=qux}.
2013-08-27Fix unsafe variable tracking in try expressionsAnthony Ramine
Variables used in the body of a try expression were marked as unsafe *and* used, which makes no sense as an unsafe variable can't be used. Function vtsubtract/2 is used to forget usage of such unsafe variables. Reported-by: Paul Davis
2013-08-27Fix variable usage tracking in erl_lintAnthony Ramine
When analyzing complex expressions (i.e. comprehensions, cases, tries, ifs and receives), erl_lint does not forget about old unused variables when returning the updated variable table. This causes a bug where old unused variables are not recorded as such: t(X, Y) -> #r{a=[ K || K <- Y ],b=[ K || K <- Y ]}. As erl_lint uses vtmerge_pat/2 to merge the results of the analysis of the two list comprehensions, X is marked as used and the warning is not emitted. The function vtmerge_pat/2 is used instead of the similar vtmerge/2 which does not mark multiple occurrences of a variable as usage to handle cases like the following one: t(X, Y) -> #r{a=A=X,b=A=Y}. Other simpler expressions like conses, tuples and external fun references do not correctly follow this behaviour, e.g. A is not marked as used in the following code: t(X, Y) -> {A=X,A=Y}. This commit fixes both issues and makes erl_lint not return old unused variables in updated tables and makes all compound expressions use vtmerge_pat/2. Reported-by: Anders Ramsell

Documentation and tests are extended to reflect the new functionality.

2013-07-21Update filelib.erl typespecsJosé Valim

Functions that expect an io:prompt() also accept binaries and iolists as arguments. Therefore its type has been updated to reflect the same types accepted by other io functions.

2013-05-28Improve erl_lint performanceJosé Valim
The default_types() in erl_lint returned a dictionary with all default types. However, calculating this dict was expensive and we actually didn't use the default values in this dictionary. This patch replaces the dictionary use for one function that checks if the type is a default type or not, and remove the bits that checked explicitly for those default types when iterating the dictionary.

2013-05-28Fix receive support in erl_eval with a BEAM moduleAnthony Ramine
Using the low-level BEAM instructions, we can loop over each message in the process queue and removes the first message that matches, without receiving them all to later send them back to itself. The function prim_eval:'receive'/2 is equivalent to the following pseudo-code: 'receive'(F, T) -> RESET MESSAGE QUEUE POINTER, LOOP: case PEEK CURRENT MESSAGE WITH TIMEOUT T of {ok,Msg} -> case F(Msg) of nomatch -> DECREMENT TIMEOUT T, ADVANCE MESSAGE QUEUE POINTER, GOTO LOOP; Result -> RESET MESSAGE QUEUE POINTER, Result end; timeout -> RESET MESSAGE QUEUE POINTER, timeout end. To not break Dialyzer and other tools, we use a stub Erlang module which abstract code is forcefully inserted into prim_inet.erl afterwards compilation.
2013-05-22Teach c:ls/1 to show non-directory filesBjörn Gustavsson
In an email to erlang-questions, Bengt Kleberg wrote: When I use c:ls/1 it reminds me so much of Unix "ls" that I expect c:ls("filename") to work. The resulting error surprises me every time (not the same day). While teaching c:ls/1 to show non-directory files, update the error handling to make use of the POSIX error codes from file:list_dir/1 and file:format_error/1 (which had not been invented when the c module was first implemented).

2013-05-20beam_lib, compile: Replace use of deprecated crypto functionsBjörn Gustavsson
Since both the STDLIB and compiler applications turn warnings into errors, we must stop using the old deprecated crypto functions. While we are at it, generalize the format of the key tuple returned by beam_lib:make_crypto_key/2 to facilitate introducing new crypto methods in the future. Change the format to: {Type,Key,IV,BlockSize} where Type, Key, and IV are the first three arguments for either crypto:block_encrypt4/ or crypto:block_decrypt/4, and BlockSize is the block size for the crypto algorithm (it is needed to properly pad the plaintext blocks before encryption).

When entering a new file, epp doesn't properly set #epp.name2 like it does on initialisation, generating a malformed file attribute when it leaves the file.
2013-04-19fix excessive CPU consumption of timer_serverAliaksey Kandratsenka
I've found stdlib's timer to burn CPU without good reason. Here's what happens. The problem is that it sleeps in milliseconds but computes time in microseconds. And there is bug in code to compute milliseconds to sleep. It computes microseconds difference between now and nearest timer event and then does _truncating_ division by 1000. So on average it sleeps 500 microseconds _less than needed_. On wakeup its checks do I have timer tick that already occurred? No. Ok how much I need to sleep ? It does that bad computation again and gets 0 milliseconds. So next gen_server timeout happens right away only to find we're still before closest timer tick and to decide to sleep 0 milliseconds again. And again and again. This commit changes division to pick ceiling of ratio rather than floor. So that we always sleep not less then difference between now and closest event time.
