Description (last modified by )
I wanted to do some testing of Sage in a loop and would check the return code to see if what I used worked or not. But this is impossible, as Sage appears to exit with 0, even if it should not have. In the example below, I try to install a non-existent package using Sage. The return code in a case like this should be non-zero, but it is not.
drkirkby@hawk:~/sage-4.5.2$ ./sage -f some-non-existant-package Force installing some-non-existant-package Calling sage-spkg on some-non-existant-package Warning: Attempted to overwrite SAGE_ROOT environment variable Building Sage on Solaris in 64-bit mode Creating SAGE_LOCAL/lib/sage-64.txt since it does not exist Detected SAGE64 flag Building Sage on Solaris in 64-bit mode some-non-existant-package Machine: SunOS hawk 5.11 snv_134 i86pc i386 i86pc Deleting directories from past builds of previous/current versions of some-non-existant-package /export/home/drkirkby/sage-4.5.2/local/bin/sage-spkg: file some-non-existant-package does not exist Attempting to download it. http://www.sagemath.org//packages/optional/some-non-existant-package.spkg --> some-non-existant-package.spkg [ ] http://www.sagemath.org//packages/standard/some-non-existant-package.spkg --> some-non-existant-package.spkg [ ] http://www.sagemath.org//packages/experimental/some-non-existant-package.spkg --> some-non-existant-package.spkg [ ] http://www.sagemath.org//packages/archive/some-non-existant-package.spkg --> some-non-existant-package.spkg [ ] ********************************************************************** * Unable to download some-non-existant-package * Please see http://www.sagemath.org//packages for a list of valid * packages or check the package name. ********************************************************************** sage: Failed to download package some-non-existant-package from http://www.sagemath.org/ drkirkby@hawk:~/sage-4.5.2$ $? bash: 0: command not found drkirkby@hawk:~/sage-4.5.2$
The same happens if one uses sage -i
to install a package. If it fails, the exit code is still 0.
In contrast, if I try this with a well written command like ls
drkirkby@hawk:~/sage-4.5.2$ ls some-non-existant-package some-non-existant-package: No such file or directory drkirkby@hawk:~/sage-4.5.2$ $? bash: 2: command not found
the exit code is non-zero - in this case 2.
Also on a similar theme is #9799, showing that make
can exit with the wrong code too.

Replying to leif:
Well, you did
sage -f ...
... I wonder what Sage returns if you dosage -i ...
instead... ;-)
The Sage. It still exits with an exit code of zero.
Btw,
sage-spkg
has lots of other flaws. I'm considering writing (and using) my own version, since I doubt the bunch of changes I aim at would get merged soon... (Same for the top-level Makefile, which by the way was namedmakefile
, I guess by some DOS programmer.)Hopefully not too many people read our tickets... :D
More, should I think.
