* origin/topic/awelzel/2120-logdir-leftover:
sqlite default-logdir test: Remove ls ./logs baseline
logging/sqlite: Recognize Log::default_logdir and place files there if set
logging: Introduce Log::default_logdir deprecate LogAscii::logdir and per writer logdir
logging/ascii: Fix .shadow paths when using LogAscii::logdir
Also modify FormatRotationPath to keep rotated logs within
Log::default_logdir unless the rotation function explicitly
set dir, e.g. by when the user redef'ed default_rotation_interval.
* 'logging/script-logdir' of https://github.com/kramse/zeek:
Copy of ascii-empty test, just changed path in the beginning
Logdir: Change requested by 0xxon, no problem
Introduce script-land variable that can be used to set logdir.
Closes GH-772
- Improved documentation/comment for the new option

logging/ascii: Support leftover log rotation in non-supervisor setups
We have a use case to rotate leftover log files in a non-supervisor
setup. There doesn't seem to be a strict requirement on supervisor
functionality. Allow enabling leftover log rotation through
LogAscii::enable_leftover_log_rotation and redef this for the
logger node in a supervisor setup individually.
These may be redefined to customize log rotation path prefixes,
including use of a directory. File extensions are still up to
individual log writers to add themselves during the actual rotation.
These new also allow for some simplication to the default
ASCII postprocessor function: it eliminates the need for it doing an
extra/awkward rename() operation that only changes the timestamp format.
This also teaches the supervisor framework to use these new options
to rotate ascii logs into a log-queue/ directory with a specific
file name format (intended for an external archiver process to
monitor separately).
* origin/topic/dev/non-ascii-logging:
Removed Policy Script for UTF-8 Logs
Commented out UTF-8 Script in Test All Policy
Minor Style Tweak
Use getNumBytesForUTF8 method to determine number of bytes
Added Jon's test cases as unit tests
Prioritizes escaping predefined Escape Sequences over Unescaping UTF-8 Sequences
Added additional check to confirm anything unescaping is a multibyte UTF-8 sequence, addressing the test case Jon brought up
Added optional script and redef bool to enable utf-8 in ASCII logs
Initial Commit, removed std::isprint check to escape
Made minor code format and logic adjustments during merge.
For backward compatibility when reading values, we first check
the ZEEK-prefixed value, and if not set, then check the corresponding
BRO-prefixed value.
When Bro writes a compressed log, it uses a file extension of ".gz".
However, upon log rotation the ascii writer script function
"default_rotation_postprocessor_func" was discarding the ".gz"
file extension. Fixed so that the correct file extension is
preserved after rotation.
This feature can be enabled globally for all logs by setting
LogAscii::gzip_level to a value greater than 0.
This feature can be enabled on a per-log basis by setting gzip-level in
$confic to a value greater than 0.
* origin/topic/seth/json-formatter:
Updating a couple of tests.
Expanded support for modifying the timestamp format in the JSON formatter.
Ascii input reader now supports all config options per-input stream.
Added an option to the JSON formatter to use ISO 8601 for timestamps.
Refactored formatters and updated the the writers a bit.
Includes some minor bugfixes and cleanup at various places, including
in old code.
- It's not *exactly* ISO 8601 which doesn't seem to support
subseconds, but subseconds are very important to us and
most things that support ISO8601 seem to also support subseconds
in the way I'm implemented it.
- Formatters have been abstracted similarly to readers and writers now.
- The Ascii writer has a new option for writing out logs as JSON.
- The Ascii writer now has all options availble as per-filter
options as well as global.
* origin/topic/bernhard/sqlite:
fix a few small rough edges (mostly comments that do no longer apply)
fix bug in input-manager regarding enums that a writer reads without 0-terminating the string
actually make sqlite work again (tests passed because the writer was not actually defined because of the define.)
add sqlite distribution.
fix warnings, update baselines, handle rotation
add sqlite tests and fix small vector/set escaping bugs
fix small bug with vectors and sets.
make work with newer AsciiFormatter.
start adding a different text for empty records for the sqlite writer.
no, you will never guess from where I copied this file...
make sqlite support more or less work for logging and input
make sqlite-writer more stable.
make it compile with new version of AsciiInputOutput
and adapt to AsciiInputOutput - seems to work...
make it compile
add SQLite reader.
...adapt to new api...
now the writer supports tables and vectors.
basic sqlite writer seems to work.
Sadly there also seems to be another deadlock issue which I am currently
not really able to figure out - on shutdown sometimes (too often) the main
thread + all sqlite threads wait for semaphores or mutexes.
First step - factored out everything the logging classes
use ( so only output ).
Moved the script-level configuration to logging/main,
and made the individual writers just refer to it -
no idea if this is good design. It works. But I am happy
about opinions :)
Next step - add support for input...
'only_single_header_row' that turns the output into CSV format.
In that mode all meta data is skipped except for a single header line
with the fields names. Example:
local my_filter: Log::Filter = [$name = "my-filter", $writer = Log::WRITER_ASCII, $config = table(["only_single_header_row"] = "T")];
