similar to the other fix, if we do not set the buffer size manually,
we get better performance for high latency connections
restore benchmark from f.gruenbicher:
no delay, without patch: ~50MB/s
no delay, with patch: ~50MB/s
25ms delay, without patch: ~11MB/s
25ms delay, with path: ~50MB/s
my own restore benchmark:
no delay, without patch: ~1.5GiB/s

by leaving the buffer sizes on default, we get much better tcp performance
for high latency links
throughput is still impacted by latency, but much less so when
leaving the sizes at default.
the disadvantage is slightly higher memory usage of the server
(details below)
my local benchmarks (proxmox-backup-client benchmark):
pbs client:
PVE Host
Epyc 7351P (16core/32thread)
64GB Memory
pbs server:
VM on Host
1 Socket, 4 Cores (Host CPU type)
4GB Memory

Before, there were mixed usages of "data store" and
"datastore" throughout the docs.
This improves consistency in the docs by using only

We need to update the atime of chunk files if they already exist,
otherwise a concurrently running GC could sweep them away.
This is protected with ChunkStore.mutex, so the fstat/unlink does not
race with touching.

The iterator of get_chunk_iterator is extended with a third parameter
indicating whether the current file is a chunk (false) or a .bad file
(true).
Count their sizes to the total of removed bytes, since it also frees
disk space.
.bad files are only deleted if the corresponding chunk exists, i.e. has
been rewritten. Otherwise we might delete data only marked bad because
of transient errors.
While at it, also clean up and use nix::unistd::unlinkat instead of
unsafe libc calls.

This ensures that following backups will always upload the chunk,
thereby replacing it with a correct version again.
Format for renaming is <digest>.<counter>.bad where <counter> is used if
a chunk is found to be bad again before a GC cleans it up.
Care has been taken to deliberately only rename a chunk in conditions
where it is guaranteed to be an error in the chunk itself. Otherwise a
broken index file could lead to an unwanted mass-rename of chunks.

a range from high to low in rust results in an empty range
(see std::ops::Range documentation)
so we need to generate the range from 0..data.len() and then reverse it
also, the task log contains a newline at the end, so we have to remove
that (should it exist)

this implements parsing and calculating calendarevents that have a
basic date component (year-mon-day) with the usual syntax options
(*, ranges, lists)
and some special events:
monthly
yearly/annually (like systemd)
quarterly
semiannually,semi-annually (like systemd)
includes some regression tests
the ~ syntax for days (the last x days of the month) is not yet
implemented

use the TryInto trait and raise an error if we cannot convert

the tm struct contains the year - 1900 but we added that
if we want to use the libc normalization correctly, the tm struct
must have the correct year in it, else the computations for timezones,
etc. fail
instead add a getter that adds the years and a setter that subtracts it again

if we give multiple options/ranges for a value, e.g.
2,4,8
we always choose the biggest, instead of the smallest that is next
this happens because in DateTimeValue::find_next(value)
'next' can be set multiple times and we set it when the new
value was *bigger* than the last found 'next' value, when in reality
we have to choose the *smallest* next we can find
reverse the comparison operator to fix this

we never passed 'false' to it anyway so remove it
(we can add it again if we should ever need it)
also remove the adding of wday (gets normalized anyway)
Signed-off-by: Dominik Csapak <d.csapak@proxmox.com>
we want to use dates for the calendarspec, and with that there are some
impossible combinations that cannot be detected during parsing
(e.g. some datetimes do not exist in some timezones, and the timezone
can change after setting the schedule)
so finding no timestamp is not an error anymore but a valid result
we omit logging in that case (since it is not an error anymore)
Signed-off-by: Dominik Csapak <d.csapak@proxmox.com>
mktime/gmtime can normalize time and even can handle special timezone
cases like the fact that the time 2:30 on specific day/timezone combos
do not exists
we have to convert the signature of all functions that use
normalize_time since mktime/gmtime can return an EOVERFLOW
but if this happens there is no way we can find a good time anyway
since normalize_time will always set wday according to the rest of the
time, remove set_wday

while it was correct, there was no measurable speed gain
(a benchmark yielded 2.8 ms for a spec that did not find a timestamp either way)

when trying to parse the task status, we seek 8k from the end
which may be into the middle of a line, so the datetime parsing
can fail (when the log message contains ': ')
This patch does a fast search for the last line, and avoid the
'lines' iterator.
for datastores where the requesting user has read or write permissions,
since the API method itself filters by that already. this is the same
permission setting and filtering that the datastore list API endpoint
