from Cask::SystemCommand.run
* stderr and stdout are now separated, though both are available
* :print_stderr is made the default, closer to previous behavior
* exit status can be read from the result object
* plist parsing is more naturally handled in the result object.
The :plist argument to the run method was removed.
* whitespace
Previously, SystemCommand commands and arguments were processed as
strings which caused problems during shell interpretation if the
arguments were not escaped properly. Now all commands are expressed
as arrays and no longer require their arguments to be escaped.
Additionally, stderr and stdout could have been interleaved in the
past and now they are always separated.
Fixes#2650 (although there is more work to be done). The issue is that
path.readlink.exist? returned false for all relative links, because readlink
reads relative to the current working directory. This caused relative
symlinks such as /usr/bin/tar to be deleted, because package mosh identified
/usr/bin as one of its container directories.
The simplest fix is not to use readlink at all, because path.exist?
will tell us what we want to know, independent of current dir.
- add new file "cask/utils.rb" analogous to "utils.rb" in Homebrew
- define odebug and odumpcask, analogs of ohai and friends, but
which only give output when --debug is in effect
- move the debug setting from an instance variable in Cask::CLI
to a method Cask.debug, defined in "lib/cask/options.rb", which
was added in #2276. (Perhaps options.rb should be merged back
into Cask::CLI).
- sprinkle odebug statements liberally throughout the codebase
- update tests
This safety feature addresses #2650 somewhat indirectly.
A list of system directories is defined. When the uninstall
process encounters a "system directory" it does not touch that
directory at all
- no chmod on that dir
- no search for broken symlinks in that dir
- no cleanup of .DS_Store files in that dir
Explictly listed files from a pkg receipts are not affected by
this change. Individual files will still be removed, even if
those files are in a special "system directory"
- do not remove *all* symlinks from referenced dirs, only broken ones
- restore dir permission after use so we don't leave behind 777 dirs
- add some better testing around `Cask::Pkg`
- clean up `FakeSystemCommand` interface in tests
refs #1274
- add `run!` method which raises if command does not succeed
- use `run!` when the command we are running must succeed for things to
move forward. this should help produce clearer error messages in
failure scenarios.
- move caveats earlier in the install process so reports can be made
about potential failures
- remove the destination tree on cask install failure, so the cask will
not be considered installed
.DS_Store files (http://en.wikipedia.org/wiki/.DS_Store) may litter
directories installed with pkgutil preventing them testing as empty and
getting deleted. Delete them along with symlinks.
- re-added a lost nil guard on `Dmg` containers
- `FakeSystemCommand` was still returning an array of split lines
instead of a string, even though its real counterpart switched to
string when install/uninstall landed
- flushed out an alfred cli bug
- moved plist parsing down to SystemCommand layer
this helps avoid a situation (which happened with `wav-tap`) where the
non-priveleged ruby code gets permision denied errors while examining the
contents of directories using `Pathname`.
accepts a single argument, which is a relative path to a pkg
inside the extracted Cask; homebrew-cask will attempt to install this
pkg after the Cask is extracted via `installer`
because of the many different ways uninstallers work, this
has several features:
- `:script`: a script in the Cask which serves as an uninstaller (e.g.
Vagrant, VirtualBox), uses `:args`, and `:input` keys to interact
with said script
- `:pkgutil`: a regexp which captures all package_ids installed by this
cask; homebrew-cask will list all files installed under these ids and
remove them
- `:launchctl`: a list of bundle_ids for services that should be
removed by homebrew-cask
- `:files`: a fallback list of files to manually remove; helps when
uninstallers miss something
