This change allows alternates to be stored in "$YADM_DIR/alt". The
correct path within the work tree will be symlinked.
Storing alternates within the work tree is still allowed. Both locations
will be considered when choosing an appropriate alternate file.
A new variable is exposed to templates, which holds the filename of the
template source. The primary use case is to be able to include a warning
message within the template. For example:
# Do not edit. This file auto-generated from {{ yadm.source }}.
Some calls to git ignored the yadm.gpg-program configuration option
and called the first git found in $PATH instead. Make them adhere to
the configured git program by replacing the call with $GIT_PROGRAM.
Previously the tracked files were sorted, and then the files and their
parent directories were considered for possible alternates. Depending on
the length of directories and names of files, inconsistencies would
occur because the directory separator (/) would be part of the sorting.
To fix this, a unique list of tracked files and their parent directories
are sorted into a single list which is processed.
Update version number and update documentation
* Add basic Zsh completion (#71, #79)
* Support directories in `.yadm/encrypt` (#81, #82)
* Support exclusions in `.yadm/encrypt` (#86)
* Improve portability with printf (#87)
* Eliminate usage of `eval` and `ls`
`eval` has always been used to process the globs in `.yadm/encrypt`.
This is being removed, as there is a risk of executing "dirty" data
found in `.yadm/encrypt`.
Caveats of this change:
* Brace and tilde expansion will no longer work in `.yadm/encrypt`
* Paths with spaces must not be quoted anymore
Directories are created prior to merge during clone, and prior to any
Git command run.
This directly addresses CVE-2017-11353.
When cloning a repo which includes data in a .ssh or .gnupg directory,
if those directories do not exist at the time of cloning, yadm will
create the directories with mask 0700 prior to merging the fetched data
into the work-tree.
When running a Git command and .ssh or .gnupg directories do not exist,
create those directories with mask 0700 prior to running the Git
command. However, do not create those directories if
yadm.auto-private-dirs is false.
