| Rarrikins | How do I report a bug in the part of the system that handles #! lines at the top of scripts? | 22:23 |
| jtaylor | that would be the kernel | 22:24 |
| jtaylor | but are you sure you found a bug? | 22:24 |
| jtaylor | thats pretty old and established code | 22:24 |
| jtaylor | anything odd is more likely a feature :) | 22:24 |
| Rarrikins | Yes, if you have a script with DOS line endings, it gives a completely wrong error message. | 22:24 |
| jtaylor | what kind of a message? | 22:25 |
| Rarrikins | ": No such file or directory" | 22:25 |
| jtaylor | thats the expected message | 22:25 |
| jtaylor | if anything goes wrong with the shebang you get that, including when it can'T find a linker etc | 22:26 |
| jtaylor | its a very hard fix | 22:26 |
| jtaylor | maybe even impossible | 22:26 |
| Rarrikins | Couldn't it be something like "Couldn't load script interpreter" or something? | 22:28 |
| Rarrikins | That's pretty uninformative as is. | 22:28 |
| jtaylor | no the kernel gives you back a ENOENT# | 22:28 |
| jtaylor | you would have to change the kernel interface and add a new error code | 22:28 |
| jtaylor | that can#t really be done | 22:28 |
| Rarrikins | You could change the error message for ENOENT. | 22:29 |
| jtaylor | then it would be wrong for all real "file not found" errors | 22:29 |
| Rarrikins | It could be made suitably generic. I think the specificity is the problem. | 22:30 |
| jtaylor | see here for some discussion: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=609882 | 22:32 |
| ubot2 | Debian bug 609882 in command-not-found "libc6: "No such file or directory" error when attempting to execute LSB executable without lsb-core" [Wishlist,Open] | 22:32 |
| Rarrikins | OK, thanks | 22:33 |
| jtaylor | its not exactly the same, but I imagine the reason it is hard to fix is the same | 22:33 |
| jtaylor | see also here: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=697299#44 | 22:34 |
| ubot2 | Debian bug 697299 in command-not-found "misleading error message when ELF interpreter does not exist" [Wishlist,Open] | 22:34 |
