Michael Eischer 38dac78180 walker: restructure FilterTree into TreeRewriter
The more generic RewriteNode callback replaces the SelectByName and
PrintExclude functions. The main part of this change is a preparation to
allow using the TreeRewriter for the `repair snapshots` command.

Michael Eischer 1a9705fc95 walker: Simplify change detection in FilterTree
Now the rewritten tree is always serialized which makes sure that we
don't accidentally miss any relevant changes.

Michael Eischer 118d599d0a Rename 'rebuild-index' to 'repair index'
The old name still works, but is deprecated.

restore: slightly reduce memory usage while restoring files
2023-04-30 16:07:43 +02:00
Michael Eischer 306a29980a Print stacktrace in SIGINT handler if RESTIC_DEBUG_STACKTRACE_SIGINT set
The builtin mechanism to capture a stacktrace in Go is to send a SIGQUIT
to the running process. However, this mechanism is not avaiable on
Windows. Thus, tweak the SIGINT handler to dump a stacktrace if the
environment variable `RESTIC_DEBUG_STACKTRACE_SIGINT` is set.

Michael Eischer 8e1e3844aa backend: factor out connection limiting and parameter validation
The SemaphoreBackend now uniformly enforces the limit of concurrent
backend operations. In addition, it unifies the parameter validation.

The List() methods no longer uses a semaphore. Restic already never runs
multiple list operations in parallel.

By managing the semaphore in a wrapper backend, the sections that hold a
semaphore token grow slightly. However, the main bottleneck is IO, so
this shouldn't make much of a difference.

The key insight that enables the SemaphoreBackend is that all of the
complex semaphore handling in `openReader()` still happens within the
original call to `Load()`. Thus, getting and releasing the semaphore
tokens can be refactored to happen directly in `Load()`. This eliminates
the need for wrapping the reader in `openReader()` to release the token.

greatroar 49e32f3f8a ui/termstatus: Optimize Truncate
x/text/width.LookupRune has to re-encode its argument as UTF-8,
while LookupString operates on the UTF-8 directly.
The uint casts get rid of a bounds check.

Benchmark results, with b.ResetTimer introduced first:

name               old time/op  new time/op  delta
TruncateASCII-8    69.7ns ± 1%  55.2ns ± 1%  -20.90%  (p=0.000 n=20+18)

greatroar a0885d5d69 fuse: Mix inode hashes in a non-symmetric way
Since 0.15 (#4020), inodes are generated as hashes of names, xor'd with
the parent inode. That means that the inode of a/b/b is

	h(a/b/b) = h(a) ^ h(b) ^ h(b) = h(a).

I.e., the grandchild has the same inode as the grandparent. GNU find
trips over this because it thinks it has encountered a loop in the
filesystem, and fails to search a/b/b. This happens more generally when
the same name occurs an even number of times.

Fix this by multiplying the parent by a large prime, so the combining
operation is not longer symmetric in its arguments. This is what the FNV
hash does, which we used prior to 0.15. The hash is now

	h(a/b/b) = h(b) ^ p*(h(b) ^ p*h(a))

Note that we already ensure that h(x) is never zero.

Collisions can still occur, but they should be much less likely to occur
within a single path.

Fixes #4253.

ParseDurationOrPanic(...).

greatroar a7786c67f1 cmd, restic: Refactor and fix snapshot filtering
This turns snapshotFilterOptions from cmd into a restic.SnapshotFilter
type and makes restic.FindFilteredSnapshot and FindFilteredSnapshots
methods on that type. This fixes #4211 by ensuring that hosts and paths
are named struct fields instead of unnamed function arguments in long
lists of such.

Timestamp limits are also included in the new type. To avoid too much
pointer handling, the convention is that time zero means no limit.
That's January 1st, year 1, 00:00 UTC, which is so unlikely a date that
we can sacrifice it for simpler code.
