This modules contains the 'ZipEncoder' struct, which wraps an async writer,
to create a ZIP archive on the fly
To create a ZIP file, have a target that implements AsyncWrite,
give it to ZipEncoder::new, add entries via 'add_entry' and
at the end, call 'finish'
for now, this does not implement compression (uses ZIPs STORE mode), and
does not support empty directories or hardlinks (or any other special
files)

Fixes a bug in which the userid of the ticket cache is updated,
when a user connects, but the ticket itself is not.
This means a newly connected user has a previously connected
user's ticket and thus, cannot do anything, as the client will
attempt to use the invalid ticket.
e.g. if john@pbs connected to the server first, followed by
mike@pbs, the following would be stored in the ticket cache.
{
"localhost": {
"mike@pbs": {
"ticket": "PBS:john@pbs:AAAA",
"timestamp": 1601039326,
"token": "BBBB"
}
}
}

The first rotation is normally the one still opened by one or more
processes for writing, so it must NOT be replaced, removed, ..., as
this then makes the remaining logging, until those processes are
noticed that they should reopen the logfile due to rotation, goes
into nirvana, which is far from ideal for a log.
Only rotating (renaming) is OK for this active file, as this does not
invalidates the file and keeps open FDs intact.
So start compressing with the second rotation, which should be clear
to use, as all writers must have been told to reopen the log during
the last rotation, reopen is a fast operation and normally triggered
at least day ago (at least if one did not dropped the state file
manually), so we are fine to archive that one for real.
If we plan to allow faster rotation the whole rotation+reopen should
be locked, so that we can guarantee that all writers switched over,
but this is unlikely to be needed.
Again, this is was logrotate sanely does by default since forever.

this is not the job of logrotate, and the real 20+ years battle
tested log rotate binary does not do so either as it's actually
pretty dangerous.
If we "replace" the file we break any logger which already opened a
new one here, e.g., a dameon starting up, and thus that writer would
log to nirvana.
It's the job of a logger to create a file if not existing, it makes
no sense to do it here.

To cater to the paranoid, a new datastore-wide setting "verify-new" is
introduced. When set, a verify job will be spawned right after a new
backup is added to the store (only verifying the added snapshot).

for now log auth errors also to the syslog, on a protected (LAN
and/or firewalled) setup this should normally happen due to
missconfiguration, not tries to break in.
This reduces syslog noise *a lot*. A current full journal output from
the current boot here has 72066 lines, of which 71444 (>99% !!) are

reuse the FileLogger module in append mode.
As it implements write, which is not thread safe (mutable self) and
we use it in a async context we need to serialize access using a
mutex.
Try to use the same format we do in pveproxy, namely the one which is
also used in apache or nginx by default.
Use the response extensions to pass up the userid, if we extract it
from a ticket.
The privileged and unprivileged dameons log both to the same file, to
have a unified view, and avoiding the need to handle more log files.
We avoid extra intra-process locking by reusing the fact that a write
smaller than PIPE_BUF (4k on linux) is atomic for files opened with
the 'O_APPEND' flag. For now the logged request path is not yet
guaranteed to be smaller than that, this will be improved in a future
patch.

Add a generous limit now and return the correct error (414 URI Too
Long). Otherwise we could to pretty larger GET requests, 64 KiB and
possible bigger (at 64 KiB my simple curl test failed due to
shell/curl limitations).
For now allow a 3072 characters as combined length of URI path and
query.
This is conform with the HTTP/1.1 RFCs (e.g., RFC 7231, 6.5.12 and
RFC 2616, 3.2.1) which do not specify any limits, upper or lower, but
require that all server accessible resources mus be reachable without
getting 414, which is normally fulfilled as we have various length
limits for stuff which could be in an URI, in place, e.g.:
* user id: max. 64 chars
* datastore: max. 32 chars
The only known problematic API endpoint is the catalog one, used in
the GUI's pxar file browser:
GET /api2/json/admin/datastore/<id>/catalog?..&filepath=<path>
The <path> is the encoded archive path, and can be arbitrary long.
But, this is a flawed design, as even without this new limit one can
easily generate archives which cannot be browsed anymore, as hyper
only accepts requests with max. 64 KiB in the URI.
So rather, we should move that to a GET-as-POST call, which has no
such limitations (and would not need to base32 encode the path).
Note: This change was inspired by adding a request access log, which
profits from such limits as we can then rely on certain atomicity
guarantees when writing requests to the log.
