This document describes the changes made to the Runtime_Tools + application.

+ +
Runtime_Tools 1.8.2 + +
Improvements and New Features + + +

+ The documentation is now built with open source tools + (xsltproc and fop) that exists on most platforms. One + visible change is that the frames are removed.

+ +
Runtime_Tools 1.8 + +
Improvements and New Features + + +

+ etop would crash if the emulator's custom + allocators had been turned off (e.g. using the + +Meamin option).

+

+ Own Id: OTP-7519

+ + +

The copyright notices have been updated.

+

+ Own Id: OTP-7851

+ + +

Now, dbg:p/2 accepts {X,Y,Z} process specification as + stated in the documentation. It also now accepts + "<X.Y.Z>" like from erlang:pid_to_list/1.

+

There is now a pre-saved match spec in dbg that saves + a lot of typing. Use dbg:ltp/0 to find out more...

Runtime_Tools 1.7.3 + +
Fixed Bugs and Malfunctions + + +

Fixed a timestamp problem where some events could be + sent out of order. Minor fixes to presentation of + data.

Runtime_Tools 1.7.2 + +
Fixed Bugs and Malfunctions + + +

etop now collects process information faster + and more reliably than before (a race condition reported + by Igor Goryachev has been eliminated).

+

Trace messages could be lost when ttb:stop/0 + was called.

+ + +
+ +
+ +
Runtime_Tools 1.7.1 + +
Improvements and New Features + + +

The documentation has been updated so as to reflect + the last updates of the Erlang shell as well as the minor + modifications of the control sequence p of the + io_lib module.

Superfluous empty lines have + been removed from code examples and from Erlang shell + examples.

+ + +

Memory management improvements especially for the + runtime system with SMP support:

The + runtime system with SMP support can now use multiple, + thread specific instances of most memory allocators. This + improves performance since it reduces lock contention in + the memory allocators. It may however increase memory + usage for some applications. The runtime system with SMP + support will by default enable this feature on most + allocators. The amount of instances used can be + configured. driver_alloc(), + driver_realloc(), and driver_free() now use + their own erts specific memory allocator instead of the + default malloc() implementation on the system. + The default configuration of some + allocators have been changed to fit applications that use + much memory better. Some new + erts_alloc configuration parameters have been + added. erts_alloc_config has been + modified to be able to create configurations suitable for + multiple instances of allocators. The + returned value from erlang:system_info({allocator, + Alloc}) has been changed. This since an allocator may + now run in multiple instances.

If you + for some reason want the memory allocators to be + configured as before, you can pass the +Mea r11b + command-line argument to erl.

For more + information see the erts_alloc(3), the + erts_alloc_config(3), and the erlang(3) + documentation.

+ +
Runtime_Tools 1.7 + +
Fixed Bugs and Malfunctions + + +

+ dbg could leave traced processes in a suspended + state if the tracer process was killed with exit reason + kill.

+

+ erlang:suspend_process/2 has been introduced which + accepts an option list as second argument. For more + information see the erlang(3) documentation.

+

+ Processes suspended via + erlang:suspend_process/[1,2] will now be + automatically resumed if the process that called + erlang:suspend_process/[1,2] terminates.

+

+ Processes could previously be suspended by one process + and resumed by another unless someone was tracing the + suspendee. This is not possible anymore. The + process resuming a process has to be the one + that suspended it.

+ + +
+ +
+ +
Runtime_Tools 1.6.8 + +
Fixed Bugs and Malfunctions + + +

+ In this release the following has been fixed and + enhanced: Autostart: It is now possible to configure + modules that shall be loaded by the autostart mechanism. + This because it is not certain that all application + systems make use of the OTP boot script to set up paths + to all Erlang modules. Runtime_tools/Inviso: A bug in the + fetch_log functionality has been fixed. Further a bug + that was (supposedly) fixed in a previous patch + concerning meta-tracer write_ti has been fixed (again) in + this patch. A bug in inviso_as_lib making remote + autostart config file updates fail has been fixed. + Inviso: inviso_tool has been given a flush API.

+

+ Own Id: OTP-6918

+ + +
+ +
+
Runtime_Tools 1.6.7 + +
Improvements and New Features + + +

+ The following bugs/improvements have been done: Internal + interworking between inviso_rt and inviso_rt_meta. The + call function used by inviso_rt to call inviso_rt_meta is + now protected with a monitor. Inviso_rt_meta now includes + the timestamp of the incoming meta trace message when + calling the call-callback. (Makes it possible to add a + "better" timestamp to the ti-file.) Bug in inviso_tool + making it not remove trace patterns when terminating. Bug + in internal function h_start_session making inviso_tool + crash if there were no active nodes to start the session + on. The user-inviso_tool and inviso API-inviso control + component request/response gen_server protocols had + default time-out. Since many trace operations can be time + consuming, a longer time-out is necessary. Improved + overload protection. It is now possible to let the + overload protection renew itself (e.g after an exit from + an external overload protector). Inviso_rt_meta now fully + uses the exception_trace match spec action term. Run + Trace Case API (as in contrast to activate and deactivate + trace case APIs) in inviso_tool. Flush trace-port API + added to inviso. Get_session_data API added to + inviso_tool. Improved inviso_tool:stop making it possible + to name nodes which shall not have their trace patterns + removed when inviso_tool terminates. Bug in handling of + writing multiple ti-entries if returned from a + call/return_from call-back in inviso_rt_meta Process + trace flags are no longer explicitly removed by the + inviso_tool when it terminates. Not necessary. + Inviso_tool get_autostart_data adopted to standard + autostarter.

+

+ *** INCOMPATIBILITY with Meta trace call-backs are called + with different arguments now. ***

+ Runtime_Tools 1.6.6 + +
+ Fixed Bugs and Malfunctions + + +

A bug in inviso_rt_meta caused an ETS table containing + information on initiated (init_tpm) functions to be lost + when suspending tracing. Further an enhancement to + inviso_rt has been introduced making it possible to + activate process trace flags based on globally registered + names. It is then not an error to activate a global name + on a node where the name does not reside. The process + count in the return value will simply be set to zero + (hence exactly one node in the NodeResult part of the + return value will indicate one matching process found). A + bug was found in fetch_log API. At the same time the + fetch_log functionality was enhanced to also offer flow + control making fetcher processes send chunks of + transferred file data at a slower pace.

An experimental tool called erts_alloc_config + has been added. erts_alloc_config is intended to + be used to aid creation of an erts_alloc + configuration that is suitable for a limited number of + runtime scenarios. For more information see the + erts_alloc_config(3) documentation.

+ Runtime_Tools 1.6.3 + +
+ Fixed Bugs and Malfunctions + + +

This ticket includes several improvements and bugfixes to + both runtime_tools and inviso. The overload mechanism can + now also react to incoming messages. This is useful if + an external overload watch-dog is used. Some improvements + of variable bindings has been done to the default + autostart mechanism - inviso_autostart_server. Autostart + "jobs" can now be done in parallel, allowing for some + jobs to hang waiting for some parts of the traced system + to become ready before proceeding. Previously when using + named meta-match-specs (tpm_ms) ending up with zero + match-specs still kept the meta trace pattern active. + This caused zero match-specs to be equal to unlimited + meta tracing on that particular function. If the internal + database becomes empty of meta match specs, meta trace + pattern is removed for that function. Standard public + loop data in the inviso runtime meta tracer process is + now extended to a 2-tuple. The functions ctp/1 and ctpl/1 + are added making it possible to remove trace patterns for + a list of functions rather than one by one. + Inviso_rt_meta will now accept a list of binaries to be + output into the trace information file, in additions to a + single binary. Further it is also possible to make own + output to the trace information file using the write_ti/1 + function. An error was discovered in inviso_rt making the + inviso_rt_meta remain rather than terminate if the + inviso_rt terminated due to "running alone" (not allowed + to run without a control component). A new tool, + inviso_tool, has been added to the inviso application.
