When AQTime detects a routine to be unsafe, it would be very helpful if AQTime could tell the line number that causes the code to be unsafe. I have spent quite a lot of time breaking down a fairly complex procedure (method) in subroutines and each time starting the AQTime profiler to to find out if the roune was safe yet.
aLine number would surely help funding out the case of the unsafe code.
Related to Case #00155347
While using AQTime Pro, I was trying to use Actions within AQTime to periodically capture fresh snapshots of my application.
I am basically setting up an action to Get Results when method FOO is Entered, and another action to Clear Results when method FOO is Exited. Unfortunately, when I try to launch the profiler, I get a message about this method being included in multiple actions. Obviously, I can work around this by adding another method that gets called within FOO and associate one of the actions to that, but I would like to avoid having to do so if possible.
I was told by customer care that this funcationality (multiple actions in one method) is currently not supported. I am requesting that it please be added in a future release. At the very least a simple solution is to still maintain this restriction, but to add a new compound Action type that does both a “Get Result” and a “Clear Result”.
The version I was using that lacked the functionality I am requesting was AQTime 8.24 build 1261.
We often have the problem that we want to profile executables, which are started indirectly by another executable, for example:
A.EXE is starting B.EXE
and B.EXE is the process, which shall be profiled.
By using AQtime, it is only possible to profile A.EXE directly.
I have seen this workaround in the forum: https://support.smartbear.com/viewarticle/43332/
But this solution is not feasible for us, because modifying the registry for this purpose is very cumbersome. An easier solution would be highly appreciated.
Currently, Performance Profiler causes program crash when profiling code using Fibers API (see Case #00169159: Program halts when run under Performance Profiler).
1) Compile attached Delphi program.
Note it uses Fiber API to implement generator:
2) Run it. The output is
3) Open in AQTime, select Performance Profiler, All Project Modules. Run.
The program halts. Event View window shows:

It is proposed that Performance Profiler correclty supports Fiber API.
The results of the "Light Coverage" profiler should merge the results of all routines with different template parameters.
Let's say, you have code like the example below. When you profile the application with AQtime (Light Coverage Profiler), you will get two lines in the results output: one for the template parameter "int", and one for the template parameter "double". None of the two routines are marked fully covered, whereas the combined/merged coverage for all template parameters would be 100%.
We have lots of code like in this example, and we are only interested in the total coverage of "silly_function", regardless of the used template parameter. Would it be possible to implement this "merge" feature into a future version of AQtime?
template <typename T>
T silly_function(const T arg)
if (arg < 5) return (arg + 1);
else return (arg - 1);
int main(int argc, char* argv)
std::cout << silly_function(4) << std::endl;
std::cout << silly_function(6.0) << std::endl;
Light Coverage result:
Routine Name % Covered
As AQTime stores absolute paths to profiled modules in the project, it would be great if it is possible to specify a new location for several modules in one shot when modules are moved or the project is opened on different computer.
We are using the "Light Coverage Profiler" with "collect info about lines: on" for creating coverage reports of our unit tests.
Let's say, you have C++ code like this:
__declspec(noreturn) void throw_bad_cast();
__declspec(noreturn) void throw_bad_cast()
And let's assume that the function is hit when the main program is executed.
However, AQtime will mark the last line of the function "throw_bad_cast" as "not covered" (the line with the closing brace).
The (invisible) return statement of the function will never be reached, so the resulting report gives the impression that the code coverage is incomplete.
Thus, it would be nice if unreachable code like this would be ignored in the coverage results so that the function is marked with "coverage 100%".
Currently, using Delphi 64bit generated code the AS operator as well as for loops with constant integers generate code that is detected by AQTime as unsafe.
Nevertheless I want to be able to profile this code, or at least allow it to fire some trigger.
So the idea is to allow these "unsafe" routines to be "forcibly" instrumented by adding them in your project as "ignore unsafe" routines.
