deleting temp files

[GoogleCodeExporter]

What steps will reproduce the problem?
1. OPen the IDE and close it.

What is the expected output? What do you see instead?
On opening the ide or the first compile there are generated several dirctories 
in the users temp directory. (build*.tmp, console*.tmp and untitled*.tmp) After 
closing the ide all directories with files in where 
left. So after some day's working with the ide you have to delete the 
directories manually.

What version of the Arduino software are you using? On what operating
system?  Which Arduino board are you using?
Arduino 1.0.1 on windows 7.

Maybe, it would help, after starting the ide, to delete all directories made by 
arduino oldern than 1 week, 1 day or something like that.

This seems to be new behavior in 1.0.1; 1.0 deleted the temp directory.  In 
fact, 1.0 deletes the build directory even if it was specified in the 
preferences file (build.path=/tmp/applet)  1.0.1 no longer deletes that, 
either...

I notice this on my install also. Arduino 1.0.2 on Windows 7.

Each time the Arduino environment is run I get a build*.tmp, console*.tmp and 
untitled*.tmp folder created. When I compile my Camera Axe project the build 
folder has 1.16MB of data files. My temp folder over time gets littered with 
garbage left behind by the Arduino environment.

The Arduino environment should delete ALL temp files it creates upon exit.

temp means "temporary". not permanent.

If there is something you want to keep around, then have an options setting to 
save those debug "log/status" files in a specified directory. Also weather or 
not those file(s) should be kept.

This issue still exists in Arduino 1.0.3 on Windows 7.
build*.tmp, console*.tmp and untitled*.tmp folders created in the TEMP folder 
for the account. * is some random 19 digit decimal number.

When I open Arduino and do nothing but close immediately the build*.tmp folder 
is deleted on Arduino exit. The others remain.

If I open a sketch of mine and do a verify and then exit. The build*.tmp folder 
stays behind with all the compiled files.

untitled*.tmp has a folder inside it named with the default new sketch name 
Arduino creates as default on open. e.g. sketch_dec19a

console*.tmp has two files. stderr and stdout.

After a few weeks of playing with Arduino I had about 50 sets of each temp 
folder littering my system TEMP folder. Arduino should clean up after itself.

This is due to the optimization as detailed in 
http://code.google.com/p/arduino/issues/detail?id=638.

Prior the IDE's "pseudo MAKE" did a clean build on every COMPILE and destructs 
the temp files, as to start over. Which actually on slower systems or with 
extensive Anti-Virus was noticeable. Paul's patch appears to have been 
incorporated at 1.0.x. Which does not delete the temp files. And uses there 
persistence to perform a build more like a refresh, rather than a clean build, 
much faster. Hence the files need to stay around between builds. in the 
preference turn on the verbose output for compilation and you see just the 
difference. 

However, it no longer deletes any of the temp files. At least for windows. 
Hence they build up. And I like to compile little changes, a lot.

It sure would be nice if the arduino.exe deleted is temp that it created, when 
it got the close signal.

I don't know if is similar problem with Linux. I don't use it much, doubt it. I 
suspect that such temp files are placed in volatile /tmp drive space, not 
surviving power cycles.

any changes for this item?

It would be good if this temp location was configurable. Also would be good if 
the random-named-folder could be avoided, changing it to always use the same 
predictably- and sensibly-named folder. That way you'd only ever have a single 
set of files, and accessing them from other programs would be much easier.
