Tools Release Notes

Tools 1.5.2

Eprof was corrected because the trace BIF and format of trace messages were changed.
Own Id: OTP-3369

The memory information obtained with the instrument module now contains an additional field, which represents the process which allocated a block.
Own Id: OTP-3142

Due to a bug in Coast, a module could be initialized repeatedly. However, it is only necessary to initiate a module once and this is now fixed.
Own Id: OTP-3225

The module dbg is moved to the Runtime tools application

In cover two or more processes, running the same code, may in rare situations give rise to race conditions when updating the ETS table used.
Own Id: OTP-2625
cover counts the number of executed statements, instead of the number of function calls. (This problem is solved by using coast instead!)
Own Id: OTP-1247
cover doesn't store the accumulated data persistently.
Own Id: OTP-1318

In Coast, recursive function calls containing other function calls as arguments are now recognised as being recursive.
Own Id: OTP-1981
In Coast there can no longer be a race condition if two (or more) processes, running the same code, tries to update the ETS tables used.
Own Id: OTP-2625

The run function call will, if the call to the Coast-compiled module fails, return an exit signal instead of the tuple {'EXIT', Reason}.
The internal representation of data has been changed, meaning that all previously Coast-compiled modules have to be recompiled.

In cover two or more processes, running the same code, may in rare situations give rise to race conditions when updating the ETS table used.
Own Id: OTP-2625
cover counts the number of executed statements, instead of the number of function calls. (This problem is solved by using coast instead!)
Own Id: OTP-1247
cover doesn't store the accumulated data persistently.
Own Id: OTP-1318

There is a new document module creating Emacs TAGS files, tags.

exref:delete_module/1 now works properly.
Own Id: OTP-1115
exref no longer have problems with guards (such as record and atom) in list comprehension (LC) expressions.
Own Id: OTP-1291
exref no longer mixes up modules.
Own Id: OTP-1220
exref no longer changes the working directory.
exref now handles internal functions correctly under certain conditions.
When using the auto option, exref no longer enters an infinite loop.

exref:module no longer accepts modules specified as strings, so the implementation now agrees with the documentation.

In Coast a recursive function call containing another function call as argument is currently not recognised as being recursive, unless the function call used as argument is made to a module not having been coast-compiled.
Own Id: OTP-1981
cover counts the number of executed statements, instead of the number of function calls. (This problem is solved by using coast instead!)
Own Id: OTP-1247
cover doesn't store the accumulated data persistently.
Own Id: OTP-1318
In Emacs occurances of $ confuses indentation mechanism.
Own Id: OTP-1203, OTP-1674, OTP-1675

The function exref:delete_module/1 does not work properly, so subesquent calls to exref:analyse will give incorrect results.
Own Id: OTP-1115

Deadlock situation with COVER compile solved.
Own Id: OTP-1072
Aux Id: HA34612
Cover does now work with include files.
OwnId: OTP-1074
Aux Id: HA34302
Changed cover to used filename:find_src/1 instead of the obsolete file_util module.

Cover did not use Options in file/2 in a correct way (OTP-1074).
Cover tried to load the "tools" application dynamically which could cause deadlock in the startup if cover-compiled modules are involved at this stage. The attempt to load the application is now removed (must be specified in the start script).
