Now all short-*, verbose, with-unit modes are handled. cat, export, json-* are
not, but those are usually used for post-processing, so I don't think it'd be
useful there.

Audit logs always have _TRANSPORT=audit and no PRIORITY= field set. This means
that they are shown in the default foreground color. There can be quite a lot
of them, and they often repeat the same information that is already logged by
applications, leading to a "wall of text" effect. Let's mark them with a
different color. This splits the logs visually into "normal logs" and "audit
logs".

Ideally, coccinelle would strip unnecessary braces too. But I do not see any
option in coccinelle for this, so instead, I edited the patch text using
search&replace to remove the braces. Unfortunately this is not fully automatic,
in particular it didn't deal well with if-else-if-else blocks and ifdefs, so
there is an increased likelikehood be some bugs in such spots.
I also removed part of the patch that coccinelle generated for udev, where we
returns -1 for failure. This should be fixed independently.

Let's always use the same, correct, way to join a namespace.

Also, while we are at it, beef it up, by adding json-seq support (i.e.
https://tools.ietf.org/html/rfc7464). This is particularly useful in
conjunction with jq's --seq switch.

These lines are generally out-of-date, incomplete and unnecessary. With
SPDX and git repository much more accurate and fine grained information
about licensing and authorship is available, hence let's drop the
per-file copyright notice. Of course, removing copyright lines of others
is problematic, hence this commit only removes my own lines and leaves
all others untouched. It might be nicer if sooner or later those could
go away too, making git the only and accurate source of authorship
information.

This part of the copyright blurb stems from the GPL use recommendations:
https://www.gnu.org/licenses/gpl-howto.en.html
The concept appears to originate in times where version control was per
file, instead of per tree, and was a way to glue the files together.
Ultimately, we nowadays don't live in that world anymore, and this
information is entirely useless anyway, as people are very welcome to
copy these files into any projects they like, and they shouldn't have to
change bits that are part of our copyright header for that.
hence, let's just get rid of this old cruft, and shorten our codebase a
bit.

Also remove the comma from the comment everywhere, I think the comma
unnecessarilly put emphasis on the clause after the comma.
Fixes #9090.
Reproducer:
systemd-journal-remote --split-mode=none -o /tmp/msg6.journal --trust=all --listen-http=8080
systemd-journal-upload -u http://localhost:8080
journalctl --file /tmp/msg6.journal -o verbose -n1
|
| |

entry
journalctl -o short would display those entries, but journalctl -o short-full
would refuse. If the entry is bad, just fall back to the receive-side realtime
timestamp like we would if it was completely missing.
|
| |
|
|
|
|
|
|
|
|
| |
If the timestamp is above 9999-12-30, (or 2038-something-something on 32 bit),
use XXXX-XX-XX XX:XX:XX as the replacement.
The problem with refusing to print timestamps is that our code accepts such
timestamps, so we can't really just refuse to process them afterwards. Also, it
makes journal files non-portable, because suddently we might completely refuse
to print entries which are totally OK on a different machine.

string operations
We'd look for a '=' separator using memchr, i.e. ignoring any nul bytes in the
string, but then do a strndup, which would terminate on any nul byte, and then
again do a memcmp, which would access memory past the chunk allocated by strndup.
Of course, we probably shouldn't allow keys with nul bytes in them. But we
currently do, so there might be journal files like that out there. So let's fix
the journal-reading code first.
|
| |
|
|
| |
This is a nice function to output some journal entries without much ado.
|
| |
|
|
|
| |
We have show_journal, and output_journal, and it's not immediately clear
how they related. Rename the first to show that it just prints one entry.

When dealing with a large number of template instances, for example
when launching daemons per VRF, it is hard for operators to correlate
log lines to arguments.
Add a new with-unit mode which, if available, prefixes unit and user
unit names when displaying its log messages instead of the syslog
identifier. It will also use the full timestamp with timezones, like
the short-full mode.

Double newlines (i.e. one empty lines) are great to structure code. But
let's avoid triple newlines (i.e. two empty lines), quadruple newlines,
quintuple newlines, …, that's just spurious whitespace.
It's an easy way to drop 121 lines of code, and keeps the coding style
of our sources a bit tigther.

Files which are installed as-is (any .service and other unit files, .conf
files, .policy files, etc), are left as is. My assumption is that SPDX
identifiers are not yet that well known, so it's better to retain the
extended header to avoid any doubt.
I also kept any copyright lines. We can probably remove them, but it'd nice to
obtain explicit acks from all involved authors before doing that.

Add new --grep option to journalctl

Red is used for highligting, the same as grep does. Except when the line is
highlighted red already, because it has high priority, in which case plain ansi
highlight is used for the matched substring.
Coloring is implemented for short and cat outputs, and not for other types.
I guess we could also add it for verbose output in the future.

Incorporating the fix from d00f1d57 into other output formats of journalctl.
If journal files are corrupted, e.g. not cleanly closed, some journal
entries can not be read by output options other than 'short' (default).
If such entries has been identified, they will now just be skipped.

This adds a new safe_fork() wrapper around fork() and makes use of it
everywhere. The new wrapper does a couple of things we previously did
manually and separately in a safer, more correct and automatic way:
1. Optionally resets signal handlers/mask in the child
2. Sets a name on all processes we fork off right after forking off (and
the patch assigns useful names for all processes we fork off now,
following a systematic naming scheme: always enclosed in () – in order
to indicate that these are not proper, exec()ed processes, but only
forked off children, and if the process is long-running with only our
own code, without execve()'ing something else, it gets am "sd-" prefix.)
3. Optionally closes all file descriptors in the child
4. Optionally sets a PR_SET_DEATHSIG to SIGTERM in the child, in a safe
way so that the parent dying before this happens being handled
safely.
5. Optionally reopens the logs
6. Optionally connects stdin/stdout/stderr to /dev/null
7. Debug logs about the forked off processes.

(#7645)
This makes things a bit easier to read I think, and also makes sure we
always use the _unlikely_ wrapper around it, which so far we used
sometimes and other times we didn't. Let's clean that up.
|
| |
|
|
|

Let's employ coccinelle to do this for us.

This option allows restricting the shown fields in the output modes that
would normally show all fields. It allows clients that are only
interested in a subset of the fields to access those more efficiently.
Also, it makes the resulting size of the output more predictable.
It has no effect on the various `short` output modes, because those
already only show a subset of the fields.

By vectorizing parse_field() the chain of parse_field() calls in
output_short() can be replaced with a single call receiving a description
of the desired fields and their targets.
While at it, eliminate the repeated strlen() calls performed on constant
field names by making parse_field() receive the field length, and storing
it in the ParseFieldVec at compile time.
Also sort the output_short() fields so the short ones are tried first, for
a minor efficiency gain.
In addition to making the code less repetitive, gcc in my tests now inlines
the parse_fieldv() call in output_short().

These are similar to memdup() and newdup(), but reserve one extra NUL
byte at the end of the new allocation and initialize it. It's useful
when copying out data from fixed size character arrays where NUL
termination can't be assumed.

e268b81e moved an fflush() from output_json() to the generic
output_journal(), when it probably should have deleted all fflush()
calls from logs-show.c altogether.
The caller supplies the FILE * to these functions, and should be in
charge of flushing as needed. The current implementation essentially
defeats any buffering stdio was bringing to the table, resulting in
extraneous tiny write() calls in commands like `journalctl -b`.
This commit removes the fflush() call from output_journal(), and adds
them to journalctl before waiting for more entries and at completion.
This way in the hot path when journalctl loops on entries stdio can
combine multiple entries into bulkier write() calls.

usec_t is always 64bit, which means it can cover quite a number of
years. However, 4 digit year display and glibc limitations around time_t
limit what we can actually parse and format. Let's make this explicit,
so that we never end up formatting dates we can#t parse and vice versa.
Note that this is really just about formatting/parsing. Internal
calculations with times outside of the formattable range are not
affected.

This new output mode formats all timestamps using the usual format_timestamp()
call we use pretty much everywhere else. Timestamps formatted this way are some
ways more useful than traditional syslog timestamps as they include weekday,
month and timezone information, while not being much longer. They are also not
locale-dependent. The primary advantage however is that they may be passed
directly to journalctl's --since= and --until= switches as soon as #3869 is
merged.
While we are at it, let's also add "short-unix" to shell completion.

With this change, binary record data is formatted as string if --all is
specified when using json output. This is inline with the effect of --all on
the other available output modes.
