case (not sure that can happen, but doesn't hurt eihter).

Fix for JSON formatter
A fatal error, especially in DEBUG, should result in a core.
Seems to fix a case where an entry in the table may be null on insert.
With this patch the model is:
- "print" cleans the data so that non-printable characters get
escaped. This is not necessarily reversible.
- to print in a reversible way, one can go through
escape_string(); this escapes backslashes as well to make the
decoding non-ambigious.
- Logging always escapes similar to escape_string(), making it
reversible.
Compared to master, we also change the escaping as follows:
- We now only escape with "\xXX", no more "^X" or "\0". Exception:
backslashes.
- We escape backlashes as "\\".
- There's no "alternative" output style anymore, i.e., fmt() '%A'
qualifier is gone.
Baselines in testing/btest are updated, external tests not yet.
Addresses BIT-1333.
is present. Testcase crashes on unpatched versions of Bro.
Found by Aaron Eppert <aeppert@gmail.com>.
This (probably) fixes the crash issue with sqlite a few people have
reported on the mailing list in the past.
- 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.
logging: table does not contain all required columns (when extending
data structures)
input: table does not contain all required columns (when extending
data structure), wrong sql statement
'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")];

This one would fail intermittently in the cases where log files were
opened or closed on a different second of the time of day from each
other since the "out" baseline contains only a single "#open" and
"#close" tag (indicating all logs opened/closed on same second of time
of day). Piping aggregated log output through the timestamp canonifier
before `uniq` makes it so "#open" and "#close" tags for different
seconds of the time of day are reduced to a single one.
- Some baselines for tests in "leaks" group were outdated.
- Changed a few of the cluster/communication tests to terminate
more explicitly instead of relying on btest-bg-wait to kill
processes. This makes the tests finish faster in the success case
and makes the reason for failing clearer in the that case.
Small tweak: I added the "same writer" constraint to the loop
condition as well. Makes sense?
* origin/fastpath:
Change path conflicts between log filters to be auto-corrected.
There seems to be a race condition in capturing the external shell's
stdout output reliably. As far as I can tell, Bro's doing everything
correctly though, the log postprocessors gets executed as expected. So
I rewrote the test to capture the output in a separate file first, and
that seems to solve the test failures.
This change makes it so when differing logging filters on the same
stream attempt to write to the same writer/path combination, the path
of the filter doing the later write will be automatically adjusted so
that it does not conflict with the other. The path is adjusted by
appending "-N", where N is the smallest integer greater or equal to 2
required to resolve the path name conflict.
Addresses #842.
Since WriterFrontend objects are looked up internally by writer type and
path, and they also expect to write consistent field arguments, it could
be the case that more than one filter of a given stream attempts to
write to the same path (derived either from $path or $path_func fields
of the filter) with the same writer type. This won't work, so now
WriterFrontend objects are bound to the filter that instantiated them so
that we can warn about other filters attempting to write to the
conflicting writer/path and the write can be skipped. Remote logs don't
appear to suffer the same issue due to pre-filtering.
Addresses #842.
Turns out the finish methods weren't called correctly, caused by a
mess up with method names which all sounded too similar and the wrong
one ended up being called. I've reworked this by changing the
thread/writer/reader interfaces, which actually also simplifies them
by getting rid of the requirement for writer backends to call their
parent methods (i.e., less opportunity for errors).
This commit also includes the following (because I noticed the problem
above when working on some of these):
- The ASCII log writer now includes "#start <timestamp>" and
"#end <timestamp> lines in the each file. The latter supersedes
Bernhard's "EOF" patch.
This required a number of tests updates. The standard canonifier
removes the timestamps, but some tests compare files directly,
which doesn't work if they aren't printing out the same
timestamps (like the comm tests).
- The above required yet another change to the writer API to
network_time to methods.
- Renamed ASCII logger "header" options to "meta".
- Fixes#763 "Escape # when first character in log file line".
All btests pass for me on Linux FC15. Will try MacOS next.
The output on stderr for this test is the results of many backgrounded
"echo" commands, one for each rotation, so the order in which they
occur may be subject to OS process scheduling and can't be relied upon
We now pass in a Info struct that contains:
- the path name (as before)
- the rotation interval
- the log_rotate_base_time in seconds
- a table of key/value pairs with further configuration options.
To fill the table, log filters have a new field "config: table[string]
of strings". This gives a way to pass arbitrary values from
script-land to writers. Interpretation is left up to the writer.
Also splits calc_next_rotate() into two functions, one of which is
thread-safe and can be used with the log_rotate_base_time value from
DoInit().
Includes also updates to the None writer:
- It gets its own script writers/none.bro.
- New bool option LogNone::debug to enable debug output. It then
prints out all the values passed to DoInit(). That's used by a
btest test to ensure the new DoInit() values are right.
- Fixed a bug that prevented Bro from terminating..
(scripts.base.frameworks.logging.rotate-custom currently fails.
Haven't yet investigated why.)

- Simplified the communication API and made it easier to change
to encrypted connections by not having separate variables to
define encrypted and unencrypted ports.
- Now, to enable listening without configuring nodes just
load the frameworks/communication/listen script.
- If encrypted listening is desired set the following:
redef Communication::listen_encrypted=T;
- Accompanying test updates.
- Removing unnecessary log flushing. Closes#498.
- Adding new BiF disconnect() that shuts a connection to a peer down.
- terminate_connection() now first flushes any still buffered log
messages.
