#40035 new defect

base aborts if current directory does not exist, even when given a port name

Reported by: larryv (Lawrence Velázquez) Owned by: larryv (Lawrence Velázquez)
Priority: Low Milestone:
Component: base Version: 2.2.0
Keywords: Cc: cooljeanius (Eric Gallager), Ionic (Mihai Moldovan), chrstphrchvz (Christopher Chavez)


Sorry for the awkward summary. This demonstrates what I mean:

% mkdir foo
% cd foo
% (cd .. && rmdir foo)
% cd $(port dir subversion)
shell-init: error retrieving current directory: getcwd: cannot access parent directories: No such file or directory
error getting working directory name: no such file or directory
    while executing
    invoked from within
"set current_portdir [pwd]"
    (file "/opt/local/bin/port" line 4857)

This error only makes sense when invoking port(1) without specifying a port, since it looks for a Portfile in the current working directory.

I assume the same behavior would be observed with the -D option.

I found that if you split up the (cd .. && rmdir foo) into two separate commands, this error doesn't happen:

Local-Admins-MacBook-Pro:foo ericgallager$ cd ..
Local-Admins-MacBook-Pro:MacPorts-fork ericgallager$ rmdir foo
Local-Admins-MacBook-Pro:MacPorts-fork ericgallager$ cd $(port dir subversion)


Local-Admins-MacBook-Pro:foo ericgallager$ (cd .. && rmdir foo)
Local-Admins-MacBook-Pro:foo ericgallager$ cd $(port dir subversion)

I guess that's because in the first case, the directory isn't actually getting deleted out from under you...

No, you're changing other semantics.

() spawns a subshell and cd .. does only apply to this child process. The parent's PWD is not affected (and will stay the deleted directory.)

This issue should be elevated to CRITICAL because it affects me!

In all seriousness, though, it's annoying. I often cd $(port work foo) to patch/do random stuff. While cleaning explicitly or running other operations on the port foo, this directory gets deleted and re-created (as it should be.)

Due to port's inability to work in an "invalid" $PWD, I have to cd . to get into the newly created dir (a zsh-only feature, I assume) and run the port operation again.

There are a number of times this error has been reported/mentioned/encountered: #24687, #33687, #33953, #41668, #52600, #58739, various mailing list posts.

I think at a minimum there should be a more helpful error message to suggest the workaround of cding to an existent/accessible directory, e.g. cd ~.
