Impact Analysis

Impact Analysis

[Brian Nulty]

Hi,

    I'm just have a look at source navigator before deciding whether to
roll it out for the site. One question I have concerns impact analysis.
Can I see what code is impacted by a change? The reason for this is to
help identify appropriate unit testing. I presume the answer encompasses
the cross-referencing capabilities.

   Any help would be  appreciated.

Cant unload files

[Tony Armitstead]

Hi,

I am using SN 4.52 on WinNT 4 SP6. My problem is that I cant unload files 
in the project editor. What happens is that I select the file, click the 
Unload button and the file is moved to an Unloaded entry in the tree 
display. If I then click the Apply button or the OK button the file is put 
back into the project. Is this a known bug?

No, it is not.

What platform are you running on? Are you running the Windows native 
version, or are you running a UNIX version X-displaying to your Windows box?

Thanks for the heads up.

We do not currently have this support in the product. One could probably 
use the SDK to create the correct queries of the XRef database.

I also run in this problem alot. I primary use SN on Windows
platform. It happens almost with files containing blanks. It's
a bug in SN.

Well, I use SN to do impact analysis all the time, but it
is a manual process. Automated impact analysis ala
"program slicing" and the like only work for really
trivial stuff. Most of the time real problems
require that you get down and dirty with the code
in ways that automated tools just can't deal with.

I am using the native Windows version. After further investigation I 
conclude this is not an trivial bug. If I create a new project and add a 
few files I can unload them without a problem. However my real project has 
lots of files spread across several directories - and this project will not 
unload the files. I also have a problem with the Edit Target dialog, 
"Source Files" tab. It seems to get upset when the file names have mixed 
case. For example  if I select all the files in the "Project Files" list 
and click the "> Add Files>" button, only those files in lower case are 
transferred. Specifically I had a file which showed up as BOOTROM.CPP. No 
way could I get that file into the "Target Files" list. I ended up having 
to rename all my source files to lower case and then everything worked as 
expected. So I wonder if SN has problems with file/path case and whether 
this could be causing the problem with removing files from the project.

I am also running into what I think is a problem with case sensitive paths 
during the build process. When I build within SN I get failures along the 
lines of:

make: *** No rule to make target `rs232server.h', needed by `bootrom.o'. Stop

Now, rs232server.h _is_ (in lower case) in the include paths as setup in 
the build settings. Specifically the directory structure is:
bootrom.cpp is in d:/tpa_ecos/BootROM
rs232server.h is in d:/tpa_ecos/BootROM/Rs232
the project is in d:/tpa_ecos/BootROM
the project build rule settings for C++ files contains the automatically 
generated entry RS232

If I generate an external makefile and look at it I see (... == stuff 
removed for clarity):

VPATH = ... D:/tpa_ecos/BootROM/RS232

CPP_INCLUDES = -I. ... -IRS232 ...

bootrom.o: rs232server.h ...

I looked in the list archives and saw a similar thread about this which 
suggested using the latest cygwin make. Well AFAIK  I am - version is 
3.79.1. Note that I also get the problem when manually 'makeing' from a 
cygwin console so this is not a SN problem but a build tools one. However 
it seems this may be related perhaps i.e. maybe the case problem is in 
cygwin and not SN.

If anyone else has seen these problems and sorted them out I would be 
grateful to know how.

Thanks.
