greatroar c23c0f7c14 Cast unix.Statfs_t.Type to int64 when checking for btrfs
Fixes #3687. Uses the cast suggested by @MichaelEischer, except that the
contant isn't cast along, because it's untyped and will be converted by
the compiler as necessary.

Michael Eischer 537b4c310a copy: Implement by reusing repack
The repack operation copies all selected blobs from a set of pack files
into new pack files. For prune the source and destination repositories
are identical. To implement copy, just use a different source and
destination repository.

Michael Eischer cd190bee14 filter: short circuit if no negative patterns 2022-03-20 13:33:08 +01:00
Vincent Bernat 2ee07ded2b filter: ability to use negative patterns
This is quite similar to gitignore. If a pattern is suffixed by an
exclamation mark and match a file that was previously matched by a
regular pattern, the match is cancelled. Notably, this can be used
with `--exclude-file` to cancel the exclusion of some files.

Like for gitignore, once a directory is excluded, it is not possible
to include files inside the directory. For example, a user wanting to
only keep `*.c` in some directory should not use:

    ~/work
    !~/work/*.c

But:

    ~/work/*
    !~/work/*.c

I didn't write documentation or changelog entry. I would like to get
feedback if this is the right approach for excluding/including files
at will for backups. I use something like this as an exclude file to
backup my home:

    $HOME/**/*
    !$HOME/Documents
    !$HOME/code
    !$HOME/.emacs.d
    !$HOME/games
    # [...]
    node_modules
    *~
    *.o
    *.lo
    *.pyc
    # [...]
    $HOME/code/linux/*
    !$HOME/code/linux/.git
    # [...]

There are some limitations for this change:

 - Patterns are not mixed accross methods: patterns from file are
   handled first and if a file is excluded with this method, it's not
   possible to reinclude it with `--exclude !something`.

 - Patterns starting with `!` are now interpreted as a negative
   pattern. I don't think anyone was relying on that.

 - The whole list of patterns is walked for each match. We may
   optimize later by exiting early if we know no pattern is starting
   with `!`.

Michael Eischer 254c8743fc Limit number of large tree blobs loaded in parallel by StreamTrees
Load tree blobs with more than 50MB only from a single goroutine. Very
large tree blobs with for example 400 MB size can otherwise require
roughly 1GB * streamTreeParallelism memory.

Michael Eischer 5ec312ca06 sftp: Implement atomic uploads
Create a temporary file with a sufficiently random name to essentially
avoid any chance of conflicts. Once the upload has finished remove the
temporary suffix. Interrupted upload thus will be ignored by restic.
2022-02-12 20:30:49 +01:00
Michael Eischer c6fd13425b remember the refreshed lock file even if removal failed
This ensures that restic won't create lots of new lock files without
deleting them later on.

In some cases a Delete operation on a backend can return a "File does
not exist" error even though the Delete operation succeeded. This can
for example be caused by request retries. This caused restic to forget
about the new lock file and continue trying to remove the old (already
deleted) lock file.
