  1. cmd/{save,split}: add a --bwlimit option.

    authored
    This allows you to limit how much upstream bandwidth 'bup save' and 'bup
    split' will use.  Specify it as a number of bytes/second, or with the 'k' or
    'M' or (lucky you!) 'G' suffixes for larger values.

  1. Work around extra space added by some readline versions.

    Peter McCurdy authored committed
    Apparently some versions of readline (6.0, for me) in some versions of
    Python (Ubuntu's python2.6.4-0ubuntu1, for me) have an irritating bug
    where they add an extra space to the end of all completions.  This is
    particularly annoying for directory completions, as you can't
    tab-complete your way into the contents of the directory.  See
    http://bugs.python.org/issue5833
    
    This patch, borrowed mostly from Trac, goes in and twiddles the
    appropriate variable inside the readline library to make it stop doing
    that.  See http://trac.edgewall.org/ticket/8711 for the discussion.

    code clarity: one-letter var carried for too long

    lelutin authored committed
    In split-cmd.py, the "w" variable is first seen on line 55 and is kept
    around until line 96. Variables that are sparsely used in a medium
    distance in the code should have a name that carries more sense when
    read on its own.
    
    Change "w" into "pack_writer" to better identify the purpose of the
    variable.

    Avoid len as a variable name

    lelutin authored committed
    As discussed earlier on the mailing list, the "len" builtin is used very
    often, and using "len" as a variable name can get confusing.
    
    Change all occurrences of "len" as a variable to "sz" to keep it short
    and meaningful.

    the whatis(1) tool cannot parse the bup manpages, because there

    using another '-', in the same fashion as git, to overcome this
    limitation.

    Documentation: some placeholders are lost

    lelutin authored committed
    Some pieces of text in the documentation files use the <...> syntax to
    mark named placeholders. However, the conversion done by pandoc from
    Markdown to makefile makes some of these placeholders disappear.
    
    The affected elements are those that contain only characters that could
    be valid for an e-mail address or a URL, but are not supposed to be one
    of both. Also, elements inside `...`-style code blocks are unaffected.
    
    Fix this situation by escaping the < and > characters where the tags
    disappear.

    bup-fuse: friendliness when python-fuse not found

    lelutin authored committed
    When used with the Python "fuse" module not installed on the system, the
    bup-fuse command exits with an error.
    
    To avoid confusing (or frustrating?) users, print a friendlier error
    message that better describes what happens.

  2. cmd/version, etc: fix version number detection stuff.

    authored
    Gabriel Filion pointed out that bup's version number (which we added to the
    man pages automatically) was not detected when you used a bup tarball
    generated from 'git archive' (or more likely, you let GitHub call 'git
    archive' for you).  That makes sense, since our version detection was based
    on having a .git directory around, which the tarball doesn't.
    
    Instead, let's create a .gitattributes file and have it auto-substitute some
    version information during 'git archive'.  Of course, if we actually *do*
    have a .git directory, continue to use that.
    
    While we're here, add a new 'bup version' command and alias "bup --version"
    and "bup -V" to call it, since those options are pretty standard.

  1. vfs: take advantage of bup chunking to make file seeking faster.

    authored
    If you have a huge file, you can now seek around inside it (eg. in 'bup
    fuse') without having to read its entire contents.  Calculating the file
    size is also really fast now.
    
    This makes a bup fuse-mounted filesystem much more useful for real-time
    access.  For example, I was able to connect to an sqlite3 database and have
    it work at a reasonable speed.  (Obviously, since 'bup fuse' is written in
    python and doesn't currently support threading, the speed could still be
    improved, but at least it's no longer godawful.)
  2. git.CatPipe: more resilience against weird errors.

    authored
    Notably, MemoryErrors thrown because the file we're trying to load into
    memory is too big to load all at once.  Now the MemoryError gets thrown, but
    the main program is potentially able to recover from it because CatPipe at
    least doesn't get into an inconsistent state.
    
    Also we can recover nicely if some lamer kills our git-cat-file subprocess.
    
    The AutoFlushIter we were using for this purpose turns out to not have been
    good enough, and it's never been used anywhere but in CatPipe, so I've
    revised it further and renamed it to git.AbortableIter.
  3. cmd/ftp: 'ls' command should print filenames in columns.

    authored
    We use the columnate() function from main.py for this, now moved into
    helpers.py.
  4. cmd/ftp: if 'get' command returns an error, print it first.

    authored
    Previously we would print "Saving 'filename'" even if we were about to
    report that 'filename' doesn't exist or is the wrong file type.
  5. vfs: cache file sizes in the Node object.

    authored
    Since the filesystem is read only, there's no reason to recalculate the file
    size every time someone asks :)
  6. cmd/fuse: add missing Stat entries to appease older versions of pytho…

    authored
    …n-fuse.
    
    python-fuse 0.2-pre3-4ubuntu1 didn't work, now it does.
    python-fuse 0.2-pre3-9 on Debian did work, still does.
  7. cmd/save: when a file is chunked, mangle its name from * to *.bup

    authored
    Files that are already named *.bup are renamed to *.bup.bupl, so that we can
    just always drop either .bup or .bupl from a filename if it's there, and the
    result will be the original filename.
    
    Also updated lib/bup/vfs.py to demangle the names appropriately, and treat
    git trees named *.bup as real chunked files (ie. by joining them back
    together).

  2. Add a 'make install' target.

    authored
    Also change main.py to search around in appropriate places for the installed
    library files.  By default, if your bup is in /usr/bin/bup, it'll look in
    /usr/lib/bup.  (It drops two words off the end of the filename and adds
    /lib/bup to the end.)
    
    This also makes the Debian packager at
    	http://git.debian.org/collab-maint/bup
    actually produce a usable package.

    Oops; we weren't checking the return value like we should.  Reported by

  4. helpers.log(): run sys.stdout.flush() first.

    authored
    It's annoying when your log messages come out before stdout messages do.
    But it's equally annoying (and inefficient) to have to flush every time you
    print something.  This seems like a nice compromise.
  5. Get rid of a sha-related DeprecationWarning in python 2.6.

    hashlib is only available in python 2.5 or higher, but the 'sha' module
    produces a DeprecationWarning in python 2.6 or higher.  We want to support
    python 2.4 and above without any stupid warnings, so let's try using
    hashlib.  If it fails, switch to the old sha module.

  1. server: only suggest a max of one pack per receive-objects cycle.

    authored
    Since the client only handles one at a time and forgets the others anyway,
    suggesting others is a bit of a waste of time... and because of the cheating
    way we figure out which index to suggest when using a midx, suggesting packs
    is more expensive than it should be anyway.
    
    The "correct" fix in the long term will be to make the client accept
    multiple suggestions at once, plus make midx files a little smarter about
    figuring out which pack is the one that needs to be suggested.  But in the
    meantime, this makes things a little nicer: there are fewer confusing log
    messages from the server, and a lot less disk grinding related to looking
    into which pack to suggest, followed by finding out that we've already
    suggested that pack anyway.
  2. rbackup-cmd: we can now backup a *remote* machine to a *local* server.

    authored
    The -r option to split and save allowed you to backup from a local machine
    to a remote server, but that doesn't always work; sometimes the machine you
    want to backup is out on the Internet, and the backup repo is safe behind a
    firewall.  In that case, you can ssh *out* from the secure backup machine to
    the public server, but not vice versa, and you were out of luck.  Some
    people have apparently been doing this:
    
        ssh publicserver tar -c / | bup split -n publicserver
    
    (ie. running tar remotely, piped to a local bup split) but that isn't
    efficient, because it sends *all* the data from the remote server over the
    network before deduplicating it locally.  Now you can do instead:
    
        bup rbackup publicserver index -vux /
        bup rbackup publicserver save -n publicserver /
    
    And get all the usual advantages of 'bup save -r', except the server runs
    locally and the client runs remotely.
Something went wrong with that request. Please try again.
