* 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.
The text from these README files appears on the "Bro Script Packages"
page after building the documentation. The text for these was mostly just
copied from the existing docs.
This cleans up most of the warnings from sphinx (broken :doc: links,
broxygen role misuses, etc.). The remaining ones should be harmless,
but not quick to silence.
I found that the README for each component was a copy from the actual
repo, so I turned those in to symlinks so they don't get out of date.
Thanks to git this merge was less troublesome that I was afraid it
would be. Not all tests pass yet though (and file hashes have changed
unfortunately).

* origin/topic/bernhard/thread-cleanup:
and just to be really sure - always make threads go through OnWaitForStop
hopefully finally fix last interesting race-condition
it is apparently getting a bit late for changes at important code...
spoke to soon (forgot to comment in line again).
Change thread shutdown again to also work with input framework.
Changing semantics of thread stop methods.
Support for cleaning up threads that have terminated.
* 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.
There's now a new directory "src/protocols/", and the plan is for each
protocol analyzer to eventually have its own subdirectory in there
that contains everything it defines (C++/pac/bif). The infrastructure
to make that happen is in place, and two analyzers have been
converted to the new model, HTTP and SSL; there's no further
HTTP/SSL-specific code anywhere else in the core anymore (I believe :-)
Further changes:
- -N lists available plugins, -NN lists more details on what these
plugins provide (analyzers, bif elements). (The latter does not
work for analyzers that haven't been converted yet).
- *.bif.bro files now go into scripts/base/bif/; and
scripts/base/bif/plugins/ for bif files provided by plugins.
- I've factored out the bifcl/binpac CMake magic from
src/CMakeLists.txt to cmake/{BifCl,Binpac}
- There's a new cmake/BroPlugin that contains magic to allow
plugins to have a simple CMakeLists.txt. The hope is that
eventually the same CMakeLists.txt can be used for compiling a
plugin either statically or dynamically.
- bifcl has a new option -c that changes the code it generates so
that it can be used with a plugin.
TODOs:
- "make install" is probably broken.
- Broxygen is probably broken for plugin-defined events.
- event groups are broken (do we want to keep them?)
Once a BasicThread leaves its run() method, a thread is now marked for
cleaning up, and the ThreadMgr will soon join it to release the OS
resources.
Also, adding a function Log::remove_stream() that remove a logging
stream, stopping all writer threads that are associated with it.
Note, however, that removing a *filter* from a stream still doesn't
clean up any threads. The problem is that because of the output paths
potentially being created dynamically it's unclear if the writer
thread will still be needed in the future. We could add clean writers
up with timeouts, but that doesn't sound great either. So for now, the
only way to sure clean up logging threads is to remove the entire
stream.
Also note that cleanup doesn't work with input threads yet, which
don't seem to terminate (at least in the case I tried).
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")];
Contributed by Carsten Langer.
Since the millisecond resolution cannot be harnessed universally and is not
supported by older version of libcurl, we will allow only specifications at the
granularity of seconds.
This commit also fixes a typing issue that causes that prevented the
ElasticSearch timeout to work in the first place: curl_easy_setopt requires a
long but was given a uint64_t.
Also reenabling the logs-to-elasticsearch.bro script in
test-all-policy.bro, that seems to work now.
* origin/fastpath:
Reworked how the logs-to-elasticsearch scripts works to stop abusing the logging framework.
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.
I've only tested that it compiles, not whether it still works. The
fact that we don't have any tests for this makes me uneasy ...
