|
||||
## Crate Features
|
||||
### Parallel execution
|
||||
The `parallel` feature enables parallel file operations via
|
||||
[Rayon](https://crates.io/crates/rayon). When creating an archive, files will be
|
||||
read and checksummed in separate threads and the data passed back to the main
|
||||
thread for writing an archive. During extraction, the main thread reads the
|
||||
archive and passes each node to a worker thread to verify it's checksum and write
|
||||
the file to disk.
|
||||
|
||||
### Colored output
|
||||
The `color` feature enables colored output when listing archive members, using
|
||||
the [termcolor](https://crates.io/crates/termcolor) crate.
|
||||
|
||||
### Reference binary
|
||||
The reference binary application can be built by running `cargo build` with the
|
||||
`bin` feature enabled. The binary enables both parallel and color features. Data
|
||||
can be in compressed form with [zstd](https://github.com/facebook/zstd) compression.
|
||||
```Sh
|
||||
cargo build --features bin
|
||||
```
|
||||
|
||||
The reference binary has been designed to closely parallel the functionality of
|
||||
**tar** while being a little nicer to use overall. Progress bars are provided by
|
||||
default, output is colorized, and a long listing format of archive members (similar
|
||||
to running `ls -l` in a directory) is available which will print various metadata
|
||||
about archive members. Quick help is available with the `--help` option.
|
||||
|
||||
### Distribution
|
||||
A *bootstrap* binary can be built with the `bootstrap` feature enabled. This
|
||||
binary can then be run to install the binary and generate and install Unix man
|
||||
pages and shell completions to a given prefix. This can be used to install all
|
||||
of the above into the filesystem, or to install into a staging directory for
|
||||
easy packaging. This feature leverages the
|
||||
[package-bootstrap](https://crates.io/crates/package-bootstrap) crate.
|
||||
|
||||
## Comparison with Tar
|
||||
The venerable Unix archiver, Tar, has the benefit of being ubiquitous on every Unix
|
||||
and Unix-like operating system. Beyond that, tar is a rather clunky format with a
|
||||
number of design flaws and quirks.
|
||||
- The original Tar specification had a hard limit in path names of 100 bytes
|
||||
- The Ustar revision of the original Tar specification only partially fixed the
|
||||
100 byte filename limit by adding a separate field in which to store the directory
|
||||
component of the pathname. Pathnames are still limited in size to 350 bytes.
|
||||
- GNU tar fixed the filename limitation with GNU tar headers. GNU tar headers are
|
||||
not documented anywhere other than the GNU tar source code, so other implementations
|
||||
have ignored the GNU format and it never caught on.
|
||||
- All metadata in a Tar header is stored in ascii. This means that things like numbers
|
||||
must be parsed from ascii.
|
||||
- Tar stores all metadata fields based on offsets from the start of the header,
|
||||
often leading to significant padding between fields.
|
||||
- File data in a Tar archive is split into 512 byte blocks. Since the final block
|
||||
must also be 512 bytes, there is yet more padding.
|
||||
- The same filename may be repeated later in a Tar archive, overwriting the first file
|
||||
during extraction.
|
||||
- All potential metadata fields always exist in a header, even if that particular field
|
||||
makes no sense in context. Example - device major and minor numbers are stored for
|
||||
regular files, directories and symlinks. This is wasted space.
|
||||
|
||||
Compared with Tar, Haggis takes a different approach. All integer values are stored
|
||||
as little endian byte arrays, exactly the same as the in memory representation of a
|
||||
little endian computer. All metadata strings are preceded by their length, requiring
|
||||
no padding between fields. The actual contents of regular files are written as a byte
|
||||
array, and again preceded by the length in bytes, so once again no padding is required.
|
||||
|
||||
If you've gotten this far, you might be noticing some differences in design philosophy.
|
||||
- Ascii is great for humans to read but terrible for computers. Since archives are
|
||||
read by computers, not humans, ascii is bad.
|
||||
- Padding is extra bytes. Sure, that overhead tends to get squashed after compressing
|
||||
an archive, but it requires more memory to create the extra zeroes and more memory
|
||||
to extract them. Better to not use padding everywhere.
|
||||
- Using offsets would always have lead to embarrassingly shortsighted limitations
|
||||
such as the filename length limitation that has plagued Tar from day one. Variable
|
||||
length fields are easily handled by storing their length first.
|
||||
- By using a flag to tell the archiver what **kind** of file is being stored, the
|
||||
archiver can expect different metadata fields for different filetypes, again saving
|
||||
on space in the file header.
|
||||
|
||||
## On compression
|
||||
The author performed some very non-scientific testing of various archive formats
|
||||
and settled on [zstd](https://github.com/facebook/zstd) as being so superior as to
|
||||
make all other common compression schemes irrelevant for **general** usage. Gzip and
|
||||
Bzip2 have woefully lower compression ratios and terrible performance. The
|
||||
[xz](https://tukaani.org/xz/) compression algorithm offers much better compression at
|
||||
the cost of poor performance. Meta may be evil overall, but zstd offers compression
|
||||
ratios on par with xz and performance that is higher than all three major competitors.
|
||||
Zstd now comes pre-installed on virtually every Linux system and is easily installed
|
||||
on BSD and other Unix-like systems. It is the new standard.
|
||||
|
||||
Other compression schemes could have been implemented into the library code, but
|
||||
that would add to the maintenance burden while not adding significantly useful
|
||||
functionality. You need to be able to open gzip compressed Tar archives because there
|
||||
are literally millions of them out there. Not so for a greenfield project such as
|
||||
Haggis. Better to encourage the use of one good compression format and discourage
|
||||
the continued use of legacy software.
|
||||
|
||||
If you absolutely **must** compress a haggis archive using gzip or bzip2, you can
|
||||
do so manually. The *haggis* binary does not provide this functionality. Don't ask.
