* pkg/config: Using current directory to store config if getting user details fails.
This patch is to use current directory to store config file.
user.Current() call fails when dlv is run inside a container. (Alpine)
* Addressing comments
* Removed whitespace
If DebugInfoDirectories is empty, set it to same value as we have in the
default configuration.
This is useful for users which already have an older config file.
Otherwise the later call to ioutil.ReadAll will return an empty array.
This issue is visible from the user's perspective due to the new
debug-info-directories parameter, which does have a value in the default
config.
As a consequence, the first 'dlv' invocation fails to find the separate
debug info files, while the second one works as expected:
$ ./dlv core /usr/bin/dockerd-current /case/dockerd.1234
could not find external debug info file
$ ./dlv core /usr/bin/dockerd-current /case/dockerd.1234
Type 'help' for list of commands.
(dlv) exit
Previously the file handle for the newly created default config was
being closed and thrown away as opposed to returned to the caller to
finish setting up config for the rest of the process. This patch changes
to return a handle to the newly created config so setup can happen as
normal. This fixes a bug where Delve can crash on first run when a
config is not present on the system.
Fixes#1129
Adds a configuration option (show-location-expr) that when activated
will cause the whatis command to also print the DWARF location
expression for a variable.
