# TODO:
# Due to the dumb re-initialization of the whole
# Ruby interpreter for every small string operation in this script,
# the current version of this script is terribly slow.
# It could be faster, if gawk/awk were used, but the
# gawk/awk has been intentionally thrown out, because the gawk and awk
# behave differently from each other. On BSD there tends to be only "awk",
# while the Linux tends to have only the "gawk".
# At some point most of this script must be re-written, reimplemented,
# in something more advanced than Bash. Most likely Ruby.
#
# The need for the rewrite comes mainly from the fact that
# the passing of string values as console parameters
# runs into the classical macro processing related problems.
# The slowness in the name of portability and correctness
# of this, first, reference implementation,
# can be tolerated for a while. The reason, why this script has been
# written in Bash at first place is that at first the goal was to
# try to create something very "simple", something that
# depends only on programs that are very likely available
# on PATH, but as it turns out, the various tests and
# string processing and other operations require
# quite a lot of more advanced tools than the Bash is, so
# the simplicity and short start-up time has been totally
# lost and the current script bears a heavy penalty from
# the relatively huge number of operating system process start-ups,
# including the relatively huge number of initializations of
# the Ruby interpreter.
#
# The lesson to be learnt from this case is that
# because projects get far more complex than
# initially anticipated, more advanced programming languages
# should be preferred to less advanced programming languages
# from the very start of the project. The current case here
# seems to be a more high level version of the microcontroller projects'
# assembler versus C dilemma.

# archival copy: https://archive.is/GRvFK
# "The Unicode versions of several functions permit a
# maximum path length of 32,767 characters,
# composed of components up to 255 characters in length.
# To specify such a path, use the "\\?\" prefix. For example,
# "\\?\D:\<path>". To specify such a UNC path, use the "\\?\UNC\"
# prefix. For example, "\\?\UNC\<server>\<share>".
# Note that these prefixes are not used as part of the path
# itself. They indicate that the path should be passed to the
# system with minimal modification. An implication of this is
# that you cannot use forward slashes to represent path separators
# or a period to represent the current directory."

#
# To allow database indexes that store the
# file names of the blogs
# to work as efficiently as possible, the first
# characters of the file name should be as
# uniformly random set of characters as possible.
# If file name starts with a secure hash, then
# that requirement is met.
#
# The parser that dismantles the file name to relevant components
# should be implementable in different programming languages
# without investing considerable amount of development time.
# The syntax of the file name should also allow the
# file name to be parsed computationally cheaply.
#
# As of 2016_05 the file extension .stblob seems to be unused.
# Therefore the "silktorrent blob", .stblob, can be used for the
# extension of the blob files.
#
# Compression of the blobs IS NOT ALLOWED, because the
# blobs must be extractable without becoming a victim
# of an attack, where 100GiB of zeros is packed to a
# small file. The container format is the tar format,
# without any compression.
