at some places, the docs were not updated yet.
for borg 1.x, -a (aka --glob-archives) expected
sh: style glob patterns ONLY (but one must not
give sh: explicitly).
for borg 2, -a (aka --match-archives) defaults
to id: style (identical match), so one must give
sh: if one wants shell-style globbing.
we now just treat that one .borg_part file we might have inside
checkpoint archives as a normal file.
people can recognize via the file name it is a partial file.
nobody cares for statistics of checkpoint files and the final
archive now does not contain any partial files any more, thus
no needs to maintain statistics about count and size of part
files.
One cannot "to not x", but one can "not to x".
Avoiding split infinitives gives the added bonus that machine
translation yields better results.
setup (n/adj) vs set(v) up. We don't "I setup it" but "I set it up".
Likewise for login(n/adj) and log(v) in, backup(n/adj) and back(v) up.
implemented by introducing one level of indirection, the limit is now
very high, so it is not practically relevant any more.
we always use the indirection (storing the metadata stream chunk ids list not
directly into the archive item, but into some repo objects referenced by the new
ArchiveItem.item_ptrs list).
thus, the code behaves the same for all archive sizes.
borg now has the chunks list in every item with content.
due to the symmetric way how borg now deals with hardlinks using
item.hlid, processing gets much simpler.
but some places where borg deals with other "sources" of hardlinks
still need to do some hardlink management:
borg uses the HardLinkManager there now (which is not much more
than a dict, but keeps documentation at one place and avoids some
code duplication we had before).
item.hlid is computed via hardlink_id function.
support hardlinked symlinks, fixes#2379
as we use item.hlid now to group hardlinks together,
there is no conflict with the item.source usage for
symlink targets any more.
2nd+ hardlinks now add to the files count as did the 1st one.
for borg, now all hardlinks are created equal.
so any hardlink item with chunks now adds to the "file" count.
ItemFormatter: support {hlid} instead of {source} for hardlinks
The previous sample for creating a ~/.borg-passphrase file creates it first and then chmod's it to 400 permissions. That's probably fine in practice, but means there's a tiny window where the passphrase file is sitting with default permissions (likely world readable, depending on the system umask).
It seems safer to first change the umask to remove all group & world bits (0077) _before_ creating the file. To be polite and avoid messing with the user's previous umask, we do this in a subshell. (Note that umask 0077 leads to a mode of 600 rather than the previous 400, because removing the owner write bit doesn't seem to buy much since the owner can just chmod the file anyway.)
"passphrase" encryption mode repos can not be created since borg 1.0.
back then, users were advised to switch existing repos of that type
to repokey mode using the "borg key migrate-to-repokey" command.
that command is still available in borg 1.0, 1.1 and 1.2, but not
any more in borg >= 1.3.
while we still might see the PassphraseKey.TYPE byte in old repos,
it is handled by the RepoKey code since borg 1.0.

It was unclear that the user _only_ needs to have borg installed on a remote system to use client/server mode. Hopefully this change makes it apparent that the user doesn't start anything on the remote system themselves.
