f4b51a2d09 fileio: rework read_one_line_file() on top of read_line() 2017-09-22 20:34:15 +02:00
189912440f def: add new constant LONG_LINE_MAX
LONG_LINE_MAX is much like LINE_MAX, but longer.

As it turns out LINE_MAX at 4096 is too short for many usecases. Since
the general concept of having a common maximum line length limit makes
sense let's add our own, and make it larger (1MB for now).

4f9a66a32d fileio: add new helper call read_line() as bounded getline() replacement
read_line() is much like getline(), and returns a line read from a
FILE*, of arbitrary sizes. In contrast to gets() it will grow the buffer
dynamically, and in contrast to getline() it will place a user-specified
boundary on the line.

time-util: testsuite fix
2017-09-22 18:47:59 +02:00
214cc95d7b time-util: mktime_or_timegm are changing the struct tm
after that wm_day etc. seems to be changed. Moving the check infront of
the mktime_or_timegm fixes that.

3fd4929b96 time-util: correctly handle the timezone when parsing
The timezone was cut off the string once the timezone was not UTC.
If it is not UTC but a other timezone that matches tzname[0] or
tzname[1], then we can leave it to the impl function to parse that
correctly. If not we can just fallback to whatever is the current
timezone is in the given t_timezone.

This should fix the testuite and tests.

ec20fe5ffb journald: make maximum size of stream log lines configurable and bump it to 48K (#6838)
This adds a new setting LineMax= to journald.conf, and sets it by
default to 48K. When we convert stream-based stdout/stderr logging into
record-based log entries, read up to the specified amount of bytes
before forcing a line-break.

This also makes three related changes:

- When a NUL byte is read we'll not recognize this as alternative line
  break, instead of silently dropping everything after it. (see #4863)

- The reason for a line-break is now encoded in the log record, if it
  wasn't a plain newline. Specifically, we distuingish "nul",
  "line-max" and "eof", for line breaks due to NUL byte, due to the
  maximum line length as configured with LineMax= or due to end of
  stream. This data is stored in the new implicit _LINE_BREAK= field.
  It's not synthesized for plain \n line breaks.

- A randomized 128bit ID is assigned to each log stream.

With these three changes in place it's (mostly) possible to reconstruct
the original byte streams from log data, as (most) of the context of
the conversion from the byte stream to log records is saved now. (So,
the only bits we still drop are empty lines. Which might be something to
look into in a future change, and which is outside of the scope of this
work)

22043e4317 networkd: change UseMTU default to true. (#6837)
Typically when DHCP server sets MTU it is a lower one. And a lower than usual
MTU is then thus required on said network to have operational networking. This
makes networkd's dhcp client to work in more similar way to other dhcp-clients
(e.g. isc-dhcp). In particular, in a cloud setting, without this default
instances have resulted in timing out talking to cloud metadata source and
failing to provision.

This does not change this default for the Annonymize code path.

00590f8268 sd-bus: style nitpick node_vtable_get_userdata()
It's confusing to use a single void* to store data with two different
types, i.e. a userdata value which is safe to pass to ->find(), and a
userdata value which identifies the found object.

Name the latter `found_u`.  This naming treats (!c->find) as a degenerate
case.  (I.e. at that point, we know the object has already been found :).

733e792bc6 sd-bus: fix response for GetAll on non-existent objects
Before this commit, if you run `loginctl user-status` from
debug-shell.service (and you have no login sessions for root), you always
see this output:

0
	Linger: no

because Properties.GetAll is returning success but without any properties,
when the only find() callback had returned 0 to mean "no object found".

After:

Could not get properties: Unknown object:
'/org/freedesktop/login1/user/self'


BTW I have a fix for more user-friendly messages from logind in this case.
It is pending in my local branch for #6829 "fix `loginctl enable-linger`".

2e72b79459 Fix for dst/non-dst timezones
The problem was with the tm.tm_isdst that is set to the current environment
value: either DST or not. While the current state is not relevant to the state
in the desired date.

Hence — it should be reset so that the mktime_or_timegm could normalise it
later.

We settled on "filename" and "file system", so change a couple of places for

binds more strongly then "name": "password file name", "output file name", etc.
Those cases are left intact.
