* origin/topic/johanna/1095-just-get-rid-of-it:
Re-add TYPE_COUNTER without function and deprecation marker.
Completely remove all traces of the COUNTER type.
* origin/topic/timw/776-using-statements:
Remove 'using namespace std' from SerialTypes.h
Remove other using statements from headers
GH-776: Remove using statements added by PR 770
Includes small fixes in files that changed since the merge request was
made.
Also includes a few small indentation fixes.
This unfortunately cuases a ton of flow-down changes because a lot of other
code was depending on that definition existing. This has a fairly large chance
to break builds of external plugins, considering how many internal ones it broke.
This change standardizes threading formatter error handling and moves
the remaining error calls to be warnings instead.
This is in line with already existing code - in most cases warnings were
raised, only a few cases raised errors. These cases do not differ
significantly from other cases in which warnings are raised.
This also fixes GH-692, in which misformatted lines prevent future file
parsing.
This commit also moves the FailWarn method that is used by both the
config and the ascii reader up to the ReaderBackend. Furthermore it
makes the Warning method of ReaderBackend respect the warning
suppression that is introduced by the FailWarn method.
The Zeek code base has very inconsistent #includes. Many sources
included a few headers, and those headers included other headers, and
in the end, nearly everything is included everywhere, so missing
#includes were never noticed. Another side effect was a lot of header
bloat which slows down the build.
First step to fix it: in each source file, its own header should be
included first to verify that each header's includes are correct, and
none is missing.
After adding the missing #includes, I replaced lots of #includes
inside headers with class forward declarations. In most headers,
object pointers are never referenced, so declaring the function
prototypes with forward-declared classes is just fine.
This patch speeds up the build by 19%, because each compilation unit
gets smaller. Here are the "time" numbers for a fresh build (with a
warm page cache but without ccache):

* 'master' of https://github.com/ZekeMedley/zeek:
Use the right delete and improve the leak test. Increases the size of the table being loaded in the pattern leak test and uses the right delete method.
Fix formatting.
Fix memory leak and add test.
Add pattern support to input framework.
This also installs symlinks from "zeek" and "bro-config" to a wrapper
script that prints a deprecation warning.
The btests pass, but this is still WIP. broctl renaming is still
missing.
#239
This change ignores leading/trailing whitespaces for a couple of
data-types (bool, port, subnet, addr) and just parses them as if the
whitespace was not present.
* origin/topic/johanna/config-framework-fixes:
Fix test that fails now that options are automatically redefable.
Make options redef-able by default.
Ascii formatter: do not complain about port text.
Make parsing of booleans a little bit more lenient.
The ascii formatter already was happy to read ports in the form
"42/tcp"; however it emitted a warning message for each line.
This patch fixes this and adds a bit more testing for the existing
behavior.
This small change allows the empty field separator to be empty. This
means that we can represent an empty list by a empty input string, which
was not possible before.
Before, an empty empty field separator meant that there is no empty
field - to get back to this behavior one now has to set the empty field
separator to a string that is guaranteed to not be part of the input
data. Note that we did not use "empty" empty field separators anywhere
and I am not aware of this being used by anyone - the new behavior seems
like it is much more useful in practice.
This also changes the config framework to interpret empty lists as...
empty, instead of interpreting them as lists that have one zero-length
element; this seems like the saner default.
Currently the destructor would try to free unallocated memory. This
could e.g. be triggered by the input framework reading a set with an
invalid element.
The configuration framework consists of three mostly distinct parts:
* option variables
* the config reader
* the script level framework
I will describe the three elements in the following.
Internally, this commit also performs a range of changes to the Input
manager; it marks a lot of functions as const and introduces a new
ValueToVal method (which could in theory replace the already existing
one - it is a bit more powerful).
This also changes SerialTypes to have a subtype for Values, just as
Fields already have it; I think it was mostly an oversight that this was
not introduced from the beginning. This should not necessitate any code
changes for people already using SerialTypes.
option variable
===============
The option keyword allows variables to be specified as run-tine options.
Such variables cannot be changed using normal assignments. Instead, they
can be changed using Option::set. It is possible to "subscribe" to
options and be notified when an option value changes.
Change handlers can also change values before they are applied; this
gives them the opportunity to reject changes. Priorities can be
specified if there are several handlers for one option.
Example script:
option testbool: bool = T;
function option_changed(ID: string, new_value: bool): bool
{
print fmt("Value of %s changed from %s to %s", ID, testbool, new_value);
return new_value;
}
event bro_init()
{
print "Old value", testbool;
Option::set_change_handler("testbool", option_changed);
Option::set("testbool", F);
print "New value", testbool;
}
config reader
=============
The config reader provides a way to read configuration files back into
Bro. Most importantly it automatically converts values to the correct
types. This is important because it is at least inconvenient (and
sometimes near impossible) to perform the necessary type conversions in
Bro scripts themselves. This is especially true for sets/vectors.
Configuration generally look like this:
[option name][tab/spaces][new variable value]
so, for example:
testaddr 2607:f8b0:4005:801::200e
testinterval 60
testtime 1507321987
test_set a b c d erdbeerschnitzel
The reader uses the option name to look up the type that variable has in
the Bro core and automatically converts the value to the correct type.
Example script use:
type Idx: record {
option_name: string;
};
type Val: record {
option_val: string;
};
global currconfig: table[string] of string = table();
event InputConfig::new_value(name: string, source: string, id: string, value: any)
{
print id, value;
}
event bro_init()
{
Input::add_table([$reader=Input::READER_CONFIG, $source="../configfile", $name="configuration", $idx=Idx, $val=Val, $destination=currconfig, $want_record=F]);
}
Script-level config framework
=============================
The script-level framework ties these two features together and makes
them a bit more convenient to use. Configuration files can simply be
specified by placing them into Config::config_files. The framework also
creates a config.log that shows all value changes that took place.
Usage example:
redef Config::config_files += {configfile};
export {
option testbool : bool = F;
}
The file is now monitored for changes; when a change occurs the
respective option values are automatically updated and the value change
is written to config.log.
This change introduces error events for Table and Event readers. Users
can now specify an event that is called when an info, warning, or error
is emitted by their input reader. This can, e.g., be used to raise
notices in case errors occur when reading an important input stream.
Example:
event error_event(desc: Input::TableDescription, msg: string, level: Reporter::Level)
{
...
}
event bro_init()
{
Input::add_table([$source="a", $error_ev=error_event, ...]);
}
For the moment, this converts all errors in the Asciiformatter into
warnings (to show that they are non-fatal) - the Reader itself also has
to throw an Error to show that a fatal error occurred and processing
will be abort.
It might be nicer to change this and require readers to mark fatal
errors as such when throwing them.
Addresses BIT-1181
* 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.
- 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.
