| 2017-12-06 | "Fix" tracing of dirty NIFs on debug builds | John Högberg | |
| When a dirty NIF is executed a "schedule in" trace event is generated, which may in turn result in a generic system task being created, causing the process to be scheduled out as it can't run dirty with pending tasks. This is usually fine since said system task is seldom created, but ERTS_FORCE_ENIF_SEND_DELAY was de-facto always on for debug builds, causing the process to bounce between dirty and normal schedulers forever. This commit is not a complete fix and it can go off the rails even on normal builds; if there's a lot of dirty jobs lined up and the receiver's msgq lock happens to be busy at the wrong time, the additional trace messages generated through this will hammer the lock and keep everything bouncing. | |||
| 2017-12-06 | Add translation for ERROR_INVALID_NAME | John Högberg | |
| Most functions return this if they're given an invalid path, eg. if they contain "<" or ">". ENOENT may seem like a strange translation, but that's what open(2) returns when fed garbage, so we'll roll with that. | |||

| erlexec adds $ROOT/erts-<vsn>/bin and $ROOT/bin first in $PATH on startup, but didn't do so if they were in the $PATH already, which meant that the bindir didn't point to the current release after a downgrade. | |||

| 2017-11-30 | Don't assume efile driver is present | John Högberg | |
| 2017-11-30 | Remove all mention of efile_drv from DTrace docs | John Högberg | |
| efile_drv is gone and so is the need for file-specific DTrace. The new implementation works fine with the normal tracing mechanism so there's nothing preventing anyone from making an erl_tracer nif that forward these events to DTrace. | |||

| 2017-11-30 | Tighten timings in dirty_*if_SUITE:dirty_scheduler_exit | John Högberg | |
| There doesn't seem to be any science behind the long delays, and the (newly introduced) dry run forces us to eat them twice, so they've been shortened to more reasonable values. | |||
| 2017-11-30 | Fix dirty_*if_SUITE after file rewrite | John Högberg | |
| Code loading is done through dirty IO now, causing the dirty_scheduler_exit tests to fail as they block their own progress by invoking erts_debug:dirty_io(wait, _); the spawned processes will exit normally before we have a chance to kill them. To get around this, we perform a dry run to ensure that all required code is loaded. It isn't particularly pretty (or fast) but it saves us the hassle of maintaining a module list (cf. embedded mode). | |||
| 2017-11-30 | Remove efile_SUITE:async_dist | John Högberg | |
| This test is irrelevant as the new implementation doesn't use async threads. | |||
| 2017-11-30 | Reimplement efile_drv as a dirty NIF | John Högberg | |
| This improves the latency of file operations as dirty schedulers are a bit more eager to run jobs than async threads, and use a single global queue rather than per-thread queues, eliminating the risk of a job stalling behind a long-running job on the same thread while other async threads sit idle. There's no such thing as a free lunch though; the lowered latency comes at the cost of increased busy-waiting which may have an adverse effect on some applications. This behavior can be tweaked with the +sbwt flag, but unfortunately it affects all types of schedulers and not just dirty ones. We plan to add type-specific flags at a later stage. sendfile has been moved to inet_drv to lessen the effect of a nasty race; the cooperation between inet_drv and efile has never been airtight and the socket dying at the wrong time (Regardless of reason) could result in fd aliasing. Moving it to the inet driver makes it impossible to trigger this by closing the socket in the middle of a sendfile operation, while still allowing it to be aborted -- something that can't be done if it stays in the file driver. The race still occurs if the controlling process dies in the short window between dispatching the sendfile operation and the dup(2) call in the driver, but it's much less likely to happen now. A proper fix is in the works. -- Notable functional differences: * The use_threads option for file:sendfile/5 no longer has any effect. * The file-specific DTrace probes have been removed. The same effect can be achieved with normal tracing together with the nif__entry/nif__return probes to track scheduling. -- OTP-14256 | |||

| 2017-11-30 | Change resource_monitors' lock order | John Högberg | |
| If a NIF monitor fired while the resource was present in an ETS table, the lock checker would erroneously report a lock order violation. This has no effect outside of debug builds. | |||

| 2017-11-30 | Add syntax in try/catch to retrieve the stacktrace directly | Björn Gustavsson | |
| This commit adds a new syntax for retrieving the stacktrace without calling erlang:get_stacktrace/0. That allow us to deprecate erlang:get_stacktrace/0 and ultimately remove it. The problem with erlang:get_stacktrace/0 is that it can keep huge terms in a process for an indefinite time after an exception. The stacktrace can be huge after a 'function_clause' exception or a failed call to a BIF or operator, because the arguments for the call will be included in the stacktrace. For example: 1> catch abs(lists:seq(1, 1000)). {'EXIT',{badarg,[{erlang,abs, [[1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20|...]], []}, {erl_eval,do_apply,6,[{file,"erl_eval.erl"},{line,674}]}, {erl_eval,expr,5,[{file,"erl_eval.erl"},{line,431}]}, {shell,exprs,7,[{file,"shell.erl"},{line,687}]}, {shell,eval_exprs,7,[{file,"shell.erl"},{line,642}]}, {shell,eval_loop,3,[{file,"shell.erl"},{line,627}]}]}} 2> erlang:get_stacktrace(). [{erlang,abs, [[1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22, 23,24|...]], []}, {erl_eval,do_apply,6,[{file,"erl_eval.erl"},{line,674}]}, {erl_eval,expr,5,[{file,"erl_eval.erl"},{line,431}]}, {shell,exprs,7,[{file,"shell.erl"},{line,687}]}, {shell,eval_exprs,7,[{file,"shell.erl"},{line,642}]}, {shell,eval_loop,3,[{file,"shell.erl"},{line,627}]}] 3> We can extend the syntax for clauses in try/catch to optionally bind the stacktrace to a variable. Here is an example using the current syntax: try Expr catch C:E -> Stk = erlang:get_stacktrace(), . . . In the new syntax, it would look like: try Expr catch C:E:Stk -> . . . Only a variable (not a pattern) is allowed in the stacktrace position, to discourage matching of the stacktrace. (Matching would also be expensive, because the raw format of the stacktrace would have to be converted to the cooked form before matching.) Note that: try Expr catch E -> . . . is a shorthand for: try Expr catch throw:E -> . . . If the stacktrace is to be retrieved for a throw, the 'throw:' prefix must be explicitly included: try Expr catch throw:E:Stk -> . . . | |||
| 2017-11-30 | Stop trying to maximize the use of x(0) | Björn Gustavsson | |
| X register 0 used to be mapped to a hardware register, and therefore faster than the other registers. Because of that, the compiler tried to use x(0) as much as possible as a temporary register. That was changed a few releases ago. X register 0 is now placed in the array of all X registers and has no special speed advantage compared to the other registers. Remove the code in the compiler that attempts to use x(0) as much as possible. As a result, the following type of instruction will be much less frequent: {put_list,Src,{x,0},{x,0}} Instead, the following type of instruction will be more frequent: {put_list,Src,{x,X},{x,X}} (Where X is an arbitrary X register.) Update the runtime system to specialize that kind of put_list instruction. | |||

| 2017-11-24 | Fix purging of modules with "fake literals" | Björn Gustavsson | |
| When compiling Erlang source code, the literal area for the module can only contain data types that have a literal syntax. However, it is possible to sneak in other data types (such as references) in the literal pool by compiling from abstract or assembly code. Those "fake literals" would work fine, but would crash the runtime system when the module containing the literals was purged. Although fake literals are not officially supported, the runtime should not crash when attempting to use them. Therefore, fix the garbage collection of literals and releasing of literal areas. https://bugs.erlang.org/browse/ERL-508 | |||
