base-1.6.0 "port uninstall" left installed files at case-sensitive FS

[ononon@…]

At HFS+ (case sensitive),

port install ncursesw
port uninstall ncursesw

make errors and some installed files are not deleted.

This is because "filemap" in Pextlib.dylib is a case-insensitive function, so

filemap set testmap "/A/Apple_Terminal" "casetest"
filemap set testmap "/a/appleII"        "casetest"
puts [filemap list testmap "casetest"]

show "/A/Apple_Terminal /A/appleII". (Note that path 'a' of 'appleII' was touppered !)

To fix this, you have only to substitute 'strncasecmp' with 'strncmp' in src/pextlib1.0/filemap.c . I guess that this fix make little influence to case-insensitive users, then expect that it is applied for our case-sensitive users.

Thanks in advance.

The attached patch should do what you're asking for. Paul, you wrote this code—will this break anything?

To answer my own question, yes, applying just this patch breaks deactivation.

From what I can tell, replacing the three instances of strncasecmp in src/pextlib1.0/filemap.c with strncmp works just fine in 1.8.1. I've tested it on both a case-sensitive filesystem and a case-insensitive disk image, and it seems to handle activation, deactivation, installation, and deinstallation of various ports, including ncursesw and qt4-mac, just fine. Unless someone else finds an error with this, I'd ask that the change be included with the next released version of MacPorts.

Have you tested on Tiger, Leopard and Snow Leopard?

Only Leopard. Sorry.

I've now tested on both Leopard and Snow Leopard, and the patch works on both.

Reverted in r60247, still breaks deactivation of some ports (e.g. ncursesw).

In which situations did it break things? I know that I tested it on 10.5, 10.6, both case sensitive and case insensitive. Is this a 10.4 issue? At worst, we could include an #ifdef for, say, 10.5 and 10.6. Thoughts?

Install without patch, apply patch, try deactivating.

Ah yes. I think that's just how any fix would have to be unless someone wants to write a migration/translation tool for the database affected.

This is probably fixed in the sqlite registry.

Seems fine to me, reopen if you still have this problem when using portdbformat sqlite.

Isn't that an unsupported option?

sqlite will be the new default registry format as of MacPorts 1.9. Please do not enable it yet with 1.8.x.
