-# Contribution guidelines
-
-Thanks for taking the time to contribute to the [collectd
-project](https://collectd.org/)! This document tries to give some guidance to
-make the process of contributing to *collectd* as pleasant as possible.
-
-## Bug reports
-
-Please report bugs as [GitHub
-Issues](https://github.com/collectd/collectd/issues). Try to answer the
-following questions:
-
-* Which version of *collectd* are you using?
-* Which operating system (distribution) are you using at which version?
-* What is the expected behavior / output?
-* What is the actual (observed) behavior / output?
-* How can we reproduce the problem you're having?
-* If *collectd* crashes, try to get a
- [stack trace](https://collectd.org/wiki/index.php/Core_file).
-
-Please monitor your issue for a couple of days and reply to questions. To keep
-the project manageable, we have to do some housekeeping; meaning we will close
-issues that have become stale.
-
-## Code contributions
-
-Please open a [GitHub Pull Request](https://github.com/collectd/collectd/pulls)
-(PR) to contribute bug fixes, features, cleanups, new plugins, … Patches sent to
-the mailing list have a tendency to fall through the cracks.
-
-* *Focus:* Fix *one thing* in your PR. The smaller your change, the faster it
- will be reviewed and merged.
-* *Coding style:* Please run `clang-format -style=file -i $FILE` after editing
- `.c`, `.h` and `.proto` files. If you don't want to install *clang-format*
- locally or your version produces a different result than the formatting
- check on Github, use `contrib/format.sh` to format files using the same web
- service used by our check.
-* *Documentation:* New config options need to be documented in two places: the
- manpage (`src/collectd.conf.pod`) and the example config
- (`src/collectd.conf.in`). New plugins need to be added to the `README` file.
-* *Continuous integration:* Once your PR is created, our continuous
- integration environment will try to build it on a number of platforms. If
- this reports a failure, please investigate and fix the problem. We will at
- best do a very casual review for failing PRs.
-* *Don't rebase:* Rebasing your branch destroys the review history. If a review
- takes a long time, we may ask you to rebase on a more recent *master*, but
- please don't do it without being asked.
-* *types.db:* One of the most common mistakes made by new contributors is the
- addition of (many) new *types* in the file `src/types.db`. The majority of
- usecases can be met with one of the existing entries. If you plan to add new
- entries to `src/types.db`, you should talk to us early in the design
- process.

- `./configure && make && make install'. For detailed, generic instructions
- see INSTALL. For a complete list of configure options and their description,

The `build.sh' script takes no arguments.
+Building on Windows
+-----------------------------------------------
+
+Collectd can be built on Windows using Cygwin, and the result is a binary that
+runs natively on Windows. That is, Cygwin is only needed for building, not running,
+collectd.
+
+You will need to install the following Cygwin packages:
+- automake
+- bison
+- flex
+- git
+- libtool
+- make
+- mingw64-x86_64-dlfcn
+- mingw64-x86_64-gcc-core
+- mingw64-x86_64-zlib
+- pkg-config
+
+To build, just run the `build.sh' script in your Cygwin terminal. By default, it installs
+to "C:/Program Files/collectd". You can change the location by setting the INSTALL_DIR
+variable:
+
+$ export INSTALL_DIR="C:/some/other/install/directory"
+$ ./build.sh
+
+or:
+
+$ INSTALL_DIR="C:/some/other/install/directory" ./build.sh
+
+

+# Contribution guidelines
+
+Thanks for taking the time to contribute to the [collectd
+project](https://collectd.org/)! This document tries to give some guidance to
+make the process of contributing to *collectd* as pleasant as possible.
+
+## Bug reports
+
+Please report bugs as [GitHub
+Issues](https://github.com/collectd/collectd/issues). Try to answer the
+following questions:
+
+* Which version of *collectd* are you using?
+* Which operating system (distribution) are you using at which version?
+* What is the expected behavior / output?
+* What is the actual (observed) behavior / output?
+* How can we reproduce the problem you're having?
+* If *collectd* crashes, try to get a
+ [stack trace](https://collectd.org/wiki/index.php/Core_file).
+
+Please monitor your issue for a couple of days and reply to questions. To keep
+the project manageable, we have to do some housekeeping; meaning we will close
+issues that have become stale.
+
+## Code contributions
+
+Please open a [GitHub Pull Request](https://github.com/collectd/collectd/pulls)
+(PR) to contribute bug fixes, features, cleanups, new plugins, … Patches sent to
+the mailing list have a tendency to fall through the cracks.
+
+* *Focus:* Fix *one thing* in your PR. The smaller your change, the faster it
+ will be reviewed and merged.
+* *Coding style:* Please run `clang-format -style=file -i $FILE` after editing
+ `.c`, `.h` and `.proto` files. If you don't want to install *clang-format*
+ locally or your version produces a different result than the formatting
+ check on Github, use `contrib/format.sh` to format files using the same web
+ service used by our check.
+* *Documentation:* New config options need to be documented in two places: the
+ manpage (`src/collectd.conf.pod`) and the example config
+ (`src/collectd.conf.in`). New plugins need to be added to the `README` file.
+* *Continuous integration:* Once your PR is created, our continuous
+ integration environment will try to build it on a number of platforms. If
+ this reports a failure, please investigate and fix the problem. We will at
+ best do a very casual review for failing PRs.
+* *Don't rebase:* Rebasing your branch destroys the review history. If a
+ review takes a long time, we may ask you to rebase on a more recent
+ *master*, but please don't do that without being asked.
+* *types.db:* One of the most common mistakes made by new contributors is the
+ addition of (many) new *types* in the file `src/types.db`. The majority of
+ usecases can be met with one of the existing entries. If you plan to add new
+ entries to `src/types.db`, you should talk to us early in the design
+ process.
+
+### ChangeLog
+
+PRs need to have a one-line summary in the *PR description*. This information
+is used to automatically generate release notes. If you got here after creating
+the PR, you need to go to the *PR description* (shown as the first "comment" on
+the PR, made by yourself) and *edit* that description. Editing a PR will
+trigger the "ChangeLog" status to be updated.
+
+For the summary itself, follow this style:
+
+```
+ChangeLog: Foo plugin: A specific issue people had has been fixed.
+```
+
+The summary must be on a line of its own, with a "ChangeLog:" prefix at the
+beginning of the line. The text should start with "Foo plugin" to give the
+reader context for the information. Other common contexts are "collectd" for
+the core daemon, "Build system", and "Documentation". Use past tense and
+passive voice the for remainder, e.g. "a bug has been fixed", "a feature has
+been added".
+
+Some PRs should be excluded from the release notes, e.g. changes to project
+internal documentation (such as this file). Those changes are not interesting
+for external users of the project and would reduce the value of the release
+notes. Maintainers may use the `Unlisted Change` label to mark those PRs.
+

+# Code Review Comments
+
+This is a collection of frequent code review comments, collected here for
+reference and discussed in more depth than a typical code review would allow.
+
+The intended use for this document is to point to it from a code review to make
+a point quickly while still providing the contributor with enough information
+to resolve the issue. For example, a good review comment would be:
+
+
+
+A link to each paragraph is provided at the beginning for easy copy'n'pasting.
+
+## Initialize variables
+
+→ [https://collectd.org/review-comments#initialize-variables](https://collectd.org/review-comments#initialize-variables)
+
+Initialize variables when declaring them. By default, C does not initialize
+local variables when they are defined. If a code path ends up reading the
+variable before it is initialized, for example because a loop body is never
+executed, it will read random data, causing undefined behavior. Worst case,
+pointers will point to random memory causing a segmentation fault.
+
+**Examples:**
+
+```c
+/* Initialize scalar with to literal: */
+int status = 0;
+
+/* Initialize pointer with function call: */
+char *buffer = calloc(1, buffer_size);
+
+/* Initialize struct with struct initializer: */
+struct addrinfo ai = {
+ .ai_family = AF_UNSPEC,
+ .ai_flags = AI_ADDRCONFIG,
+ .ai_socktype = SOCK_STREAM,
+};
+
+/* Initialize struct with zero: */
+struct stat statbuf = {0};
+```
+
+In the last example, `{0}` is the universal struct initializer that, in theory,
+should be able to zero-initialize any struct. In practise, however, some
+compilers don't implement this correctly and will get confused when the first
+member is a struct or a union. Our *continuous integration* framework will
+catch these cases.
+
+## Define variables on first use
+
+→ [https://collectd.org/review-comments#define-variables-on-first-use](https://collectd.org/review-comments#define-variables-on-first-use)
+
+Local variables should be defined when they are first used, ideally when they
+can be initialized. For example:
+
+```c
+struct foo *f = calloc(1, sizeof(*f));
+if (f == NULL) {
+ return ENOMEM;
+}
+
+/* GOOD: status defiened and initialized late. */
+int status = function_call(f);
+```
+
+Sometimes variables are initialized by passing a pointer to them to a function.
+In that case define them as close to the function call as you can and
+zero-initialize them. The function may only partially initialize a struct or
+not initialize a struct at all in some circumstances.
+
+**Example:**
+
+```c
+char const *path = determine_path();
+
+struct stat s = {0};
+int status = stat(path, &s);
+```
+
+Old C standards (C89 and ealier) required variables to be defined at the
+beginning of a scope block. The following *bad* style is still frequently
+found:
+
+```c
+/* BAD: local variables defined at beginning of block. */
+struct foo *f;
+int status;
+
+f = calloc(1, sizeof(*f));
+if (f == NULL) {
+ return ENOMEM;
+}
+
+status = function_call(f);
+```

+
+The plugin's configuration consists of a I<Transport> that configures
+communications to the AMQP 1.0 messaging bus and one or more I<Instance>
+corresponding to metric or event publishers to the messaging system.
+
+The address in the I<Transport> block concatenated with the name given in the
+I<Instance> block starting tag will be used as the send-to address for
+communications over the messaging link.
+
+The following options are accepted within each I<Transport> block:
+
+=over 4
+
+=item B<Host> I<Host>
+
+Hostname or IP-address of the AMQP 1.0 intermediary. Defaults to the
+default behavior of the underlying communications library,
+I<libqpid-proton>, which is "localhost".
+
+=item B<Port> I<Port>
+
+Service name or port number on which the AMQP 1.0 intermediary accepts
+connections. This argument must be a string, even if the numeric form
+is used. Defaults to "5672".
+
+=item B<User> I<User>
+
+=item B<Password> I<Password>
+
+Credentials used to authenticate to the AMQP 1.0 intermediary. By
+default "guest"/"guest" is used.
+
+=item B<Address> I<Address>
+
+This option specifies the prefix for the send-to value in the message.
+By default, "collectd" will be used.
+
+=item B<RetryDelay> I<RetryDelay>
+
+When the AMQP1 connection is lost, defines the time in seconds to wait
+before attempting to reconnect. Defaults to 1, which implies attempt
+to reconnect at 1 second intervals.
+
+=back
+
+The following options are accepted within each I<Instance> block:
+
+=over 4
+
+=item B<Format> B<Command>|B<JSON>|B<Graphite>
+
+Selects the format in which messages are sent to the intermediary. If set to
+B<Command> (the default), values are sent as C<PUTVAL> commands which are
+identical to the syntax used by the I<Exec> and I<UnixSock plugins>. In this
+case, the C<Content-Type> header field will be set to C<text/collectd>.
+
+If set to B<JSON>, the values are encoded in the I<JavaScript Object Notation>,
+an easy and straight forward exchange format. The C<Content-Type> header field
+will be set to C<application/json>.
+
+If set to B<Graphite>, values are encoded in the I<Graphite> format, which is
+"<metric> <value> <timestamp>\n". The C<Content-Type> header field will be set to
+C<text/graphite>.
+
+A subscribing client I<should> use the C<Content-Type> header field to
+determine how to decode the values.
+
+=item B<PreSettle> B<true>|B<false>
+
+If set to B<false> (the default), the plugin will wait for a message
+acknowledgement from the messaging bus before sending the next
+message. This indicates transfer of ownership to the messaging
+system. If set to B<true>, the plugin will not wait for a message
+acknowledgement and the message may be dropped prior to transfer of
+ownership.
+
+=item B<Notify> B<true>|B<false>
+
+If set to B<false> (the default), the plugin will service the
+instance write call back as a value list. If set to B<true> the
+plugin will service the instance as a write notification callback
+for alert formatting.
+
+=item B<StoreRates> B<true>|B<false>
+
+Determines whether or not C<COUNTER>, C<DERIVE> and C<ABSOLUTE> data sources
+are converted to a I<rate> (i.e. a C<GAUGE> value). If set to B<false> (the
+default), no conversion is performed. Otherwise the conversion is performed

+=item B<RestoreAffinityPolicy> I<AllCPUs>|I<Restore>
+
+Reading data from CPU has side-effect: collectd process's CPU affinity mask
+changes. After reading data is completed, affinity mask needs to be restored.
+This option allows to set restore policy.
+
+B<AllCPUs> (the default): Restore the affinity by setting affinity to any/all
+CPUs.
+
+B<Restore>: Save affinity using sched_getaffinity() before reading data and
+restore it after.
+
+On some systems, sched_getaffinity() will fail due to inconsistency of the CPU
+set size between userspace and kernel. In these cases plugin will detect the
+unsuccessful call and fail with an error, preventing data collection.
+Most of configurations does not need to save affinity as Collectd process is
+allowed to run on any/all available CPUs.
+
+If you need to save and restore affinity and get errors like 'Unable to save
+the CPU affinity', setting 'possible_cpus' kernel boot option may also help.

=item B<Connection> I<uri>
The default is to collect statistics for all domains and all their devices.
-Example:
+B<Note:> B<BlockDevice> and B<InterfaceDevice> options are related to
+corresponding B<*Format> options. Specifically, B<BlockDevice> filtering depends
+on B<BlockDeviceFormat> setting - if user wants to filter block devices by
+'target' name then B<BlockDeviceFormat> option has to be set to 'target' and
+B<BlockDevice> option must be set to a valid block device target
+name("/:hdb/"). Mixing formats and filter values from different worlds (i.e.,
+using 'target' name as B<BlockDevice> value with B<BlockDeviceFormat> set to
+'source') may lead to unexpected results (all devices filtered out or all
+visible, depending on the value of B<IgnoreSelected> option).
+Similarly, option B<InterfaceDevice> is related to B<InterfaceFormat> setting
+(i.e., when user wants to use MAC address as a filter then B<InterfaceFormat>
+has to be set to 'address' - using wrong type here may filter out all of the
+interfaces).
+
+B<Example 1:>
+
+Ignore all I<hdb> devices on any domain, but other block devices (eg. I<hda>)
+will be collected:
BlockDevice "/:hdb/"
IgnoreSelected "true"
+ BlockDeviceFormat "target"
-Ignore all I<hdb> devices on any domain, but other block devices (eg. I<hda>)
-will be collected.
+B<Example 2:>
+
+Collect metrics only for block device on 'baremetal0' domain when its
+'source' matches given path:
+
+ BlockDevice "baremetal0:/var/lib/libvirt/images/baremetal0.qcow2"
+ BlockDeviceFormat source
+
+As you can see it is possible to filter devices/interfaces using
+various formats - for block devices 'target' or 'source' name can be
+used. Interfaces can be filtered using 'name', 'address' or 'number'.
+
+B<Example 3:>
+
+Collect metrics only for domains 'baremetal0' and 'baremetal1' and
+ignore any other domain:
+
+ Domain "baremetal0"
+ Domain "baremetal1"
+
+It is possible to filter multiple block devices/domains/interfaces by
+adding multiple filtering entries in separate lines.

+flexible configuration options and adds features such as using TCP for transport.
+The plugin can connect to a I<Syslog> daemon, like syslog-ng and rsyslog, that will
+ingest metrics, transform and ship them to the specified output.
+The plugin uses I<TCP> over the "line based" protocol with a default port 44514.

+When set, I<HostTags> is added to the end of the metric.
+It is intended to be used for adding additional metadata to tag the metric with.
+Dots and whitespace are I<not> escaped in this string.
+
+Examples:
+
+When MessageFormat is set to "human".
+
+ ["prefix1" "example1"="example1_v"]["prefix2" "example2"="example2_v"]"
+
+When MessageFormat is set to "JSON", text should be in JSON format.
+Escaping the quotation marks is required.
+
+ HostTags "\"prefix1\": {\"example1\":\"example1_v\",\"example2\":\"example2_v\"}"
+
+=item B<MessageFormat> I<String>
+
+I<MessageFormat> selects the format in which messages are sent to the
+syslog deamon, human or JSON. Defaults to human.
+
+Syslog message format:
+
+<priority>VERSION ISOTIMESTAMP HOSTNAME APPLICATION PID MESSAGEID STRUCTURED-DATA MSG
+
+The difference between the message formats are in the STRUCTURED-DATA and MSG parts.
+
+Human format:
+
+ <166>1 ISOTIMESTAMP HOSTNAME collectd PID MESSAGEID
+ ["collectd" "value": "v1" "plugin"="plugin_v" "plugin_instance"="plugin_instance_v"
+ "type_instance"="type_instance_v" "type"="type_v" "ds_name"="ds_name_v" "interval"="interval_v" ]
+ "host_tag_example"="host_tag_example_v" plugin_v.type_v.ds_name_v="v1"
+
+JSON format:
+
+ <166>1 ISOTIMESTAMP HOSTNAME collectd PID MESSAGEID STRUCTURED-DATA
+ {
+ "collectd": {
+ "time": time_as_epoch, "interval": interval_v, "plugin": "plugin_v",
+ "plugin_instance": "plugin_instance_v", "type":"type_v",
+ "type_instance": "type_instance_v", "plugin_v": {"type_v": v1}
+ } , "host":"host_v", "host_tag_example": "host_tag_example_v"
+ }
+
+=item B<StoreRates> B<false>|B<true>
+
+If set to B<true>, convert counter values to rates. If set to B<false>
+(the default) counter values are stored as is, as an increasing
+integer number.
+
+=item B<AlwaysAppendDS> B<false>|B<true>
+
+If set to B<true>, append the name of the I<Data Source> (DS) to the "metric"
+identifier. If set to B<false> (the default), this is only done when there is
+more than one DS.
+
+=item B<Prefix> I<String>
+
+When set, I<Prefix> is added to all metrics names as a prefix. It is intended in
+case you want to be able to define the source of the specific metric. Dots and
+whitespace are I<not> escaped in this string.
+
+=back
+
=head2 Plugin C<xencpu>
This plugin collects metrics of hardware CPU load for machine running Xen
=head1 IGNORELISTS
B<Ignorelists> are a generic framework to either ignore some metrics or report
-specific metircs only. Plugins usually provide one or more options to specify
+specific metrics only. Plugins usually provide one or more options to specify
the items (mounts points, devices, ...) and the boolean option
C<IgnoreSelected>.

+ * BIG_ENDIAN if BYTE_ORDER == BIG_ENDIAN, the host byte
+ * order is from most significant to least

+ * uint64_t bswap64(uint64_t x);

+ *
+ * __ENDIAN_LITTLE__ if BYTE_ORDER == LITTLE_ENDIAN then this

+ *
+ * This approach is intended to avoid the need for preflight configure
+ scripts.
+ * An alternative approach would be to test compiler CPU architecture marcros.
+ *
+ * This header has had *limited* testing on recent C11/C++11 compilers and is
+ * based on the austin bug tracker interface, manpages, and headers present in
+ * Linux, FreeBSD, Windows, Solaris and Darwin.
+ *
+ * The header uses __builtin_bswapXX intrinsic with GCC/Clang (__GNUC__) on
+ * platforms that do not provide bswap16, bswap32, bswap64 (Darwin)

+ * COPYRIGHT (C) 1986 Gary S. Brown. You may use this program, or
+ * code or tables extracted from it, as desired without restriction.
+ *
+ * First, the polynomial itself and its table of feedback terms. The
+ * polynomial is
+ * X^32+X^26+X^23+X^22+X^16+X^12+X^11+X^10+X^8+X^7+X^5+X^4+X^2+X^1+X^0
+ *
+ * Note that we take it "backwards" and put the highest-order term in
+ * the lowest-order bit. The X^32 term is "implied"; the LSB is the
+ * X^31 term, etc. The X^0 term (usually shown as "+1") results in
+ * the MSB being 1
+ *
+ * Note that the usual hardware shift register implementation, which
+ * is what we're using (we're merely optimizing it by doing eight-bit
+ * chunks at a time) shifts bits into the lowest-order term. In our
+ * implementation, that means shifting towards the right. Why do we
+ * do it this way? Because the calculated CRC must be transmitted in
+ * order from highest-order term to lowest-order term. UARTs transmit
+ * characters in order from LSB to MSB. By storing the CRC this way
+ * we hand it to the UART in the order low-byte to high-byte; the UART
+ * sends each low-bit to hight-bit; and the result is transmission bit
+ * by bit from highest- to lowest-order term without requiring any bit
+ * shuffling on our part. Reception works similarly
+ *
+ * The feedback terms table consists of 256, 32-bit entries. Notes
+ *
+ * The table can be generated at runtime if desired; code to do so
+ * is shown later. It might not be obvious, but the feedback
+ * terms simply represent the results of eight shift/xor opera
+ * tions for all combinations of data and CRC register values
+ *
+ * The values must be right-shifted by eight bits by the "updcrc
+ * logic; the shift must be unsigned (bring in zeroes). On some
+ * hardware you could probably optimize the shift in assembler by
+ * using byte-swap instructions

+ * matches, the callback passed in `callback' will be called along with the
+ * pointer `user_pointer'.
+ * The string that's passed to the callback depends on the regular expression:
+ * If the regular expression includes a sub-match, i. e. something like
+ * "value=([0-9][0-9]*)"
+ * then only the submatch (the part in the parenthesis) will be passed to the
+ * callback. If there is no submatch, then the entire string is passed to the
+ * callback.
+ * The optional `excluderegex' allows to exclude the line from the match, if
+ * the excluderegex matches.
+ * When `match_destroy' is called the `user_data' pointer is freed using
+ * the `free_user_data' callback - if it is not NULL.

+ DESCRIPTION
+ The cu_mount_checkoption() function is a replacement of
+ char *hasmntopt(const struct mntent *mnt, const char *opt).
+ In fact hasmntopt() just looks for the first occurrence of the
+ characters at opt in mnt->mnt_opts. cu_mount_checkoption()
+ checks for the *option* keyword in line, starting at the
+ first character of line or after a ','.
+
+ If full is not 0 then also the end of keyword has to match
+ either the end of line or a ',' after keyword.
+
+ RETURN VALUE
+ The cu_mount_checkoption() function returns a pointer into
+ string line if a match of keyword is found. If no match is
+ found cu_mount_checkoption() returns NULL.
+
+ NOTES
+ Do *not* try to free() the pointer which is returned! It is
+ just part of the string line.
+
+ full should be set to 0 when matching options like: rw, quota,
+ noatime. Set full to 1 when matching options like: loop=,
+ gid=, commit=.
+
+ EXAMPLES
+ If line is "rw,usrquota,grpquota", keyword is "quota", NULL
+ will be returned (independend of full).
+
+ If line is "rw,usrquota,grpquota", keyword is "usrquota",
+ a pointer to "usrquota,grpquota" is returned (independend
+ of full).
+
+ If line is "rw,loop=/dev/loop1,quota", keyword is "loop="
+ and full is 0, then a pointer to "loop=/dev/loop1,quota"
+ is returned. If full is not 0 then NULL is returned. But
+ maybe you might want to try cu_mount_getoptionvalue()...
+*/
+
+char *cu_mount_getoptionvalue(char *line, const char *keyword);
+/*
+ DESCRIPTION
+ The cu_mount_getoptionvalue() function can be used to grab
+ a VALUE out of a mount option (line) like:
+ loop=VALUE
+ whereas "loop=" is the keyword.
+
+ RETURN VALUE
+ If the cu_mount_getoptionvalue() function can find the option
+ keyword in line, then memory is allocated for the value of
+ that option and a pointer to that value is returned.
+
+ If the option keyword is not found, cu_mount_getoptionvalue()
+ returns NULL;
+
+ NOTES
+ Internally it calls cu_mount_checkoption(), then it
+ allocates memory for VALUE and returns a pointer to that
+ string. So *do not forget* to free() the memory returned
+ after use!!!

+ *
+ * Description:
+ * The OVS util module provides the following features:
+ * - Implements the OVS DB communication transport specified
+ * by RFC7047:
+ * * Connect/disconnect to OVS DB;
+ * * Recovery mechanism in case of OVS DB connection lost;
+ * * Subscription mechanism to OVS DB table update events
+ * (insert/modify/delete);
+ * * Send custom JSON request to OVS DB (poll table data, etc.)
+ * * Handling of echo request from OVS DB server to verify the
+ * liveness of the connection.
+ * - Provides YAJL helpers functions.
+ *
+ * OVS DB API User Guide:
+ * All OVS DB function/structure names begins from 'ovs_db_*' prefix. To
+ * start using OVS DB API, client (plugin) should initialize the OVS DB
+ * object (`ovs_db_t') by calling `ovs_db_init' function. It initializes
+ * internal data and creates two main workers (threads). The result of the
+ * function is a pointer to new OVS DB object which can be used by other
+ * OVS DB API later and must be released by `ovs_db_destroy' function if
+ * the object isn't needed anymore.
+ * Once OVS DB API is initialized, the `init_cb' callback is called if
+ * the connection to OVS DB has been established. This callback is called
+ * every time the OVS DB is reconnected. So, if the client registers table
+ * update event callbacks or does any other OVS DB setup that can be lost
+ * after OVS DB reconnecting, it should be done in `init_cb' callback.
+ * The `ovs_db_table_cb_register` function is used to register OVS DB
+ * table update event callback and receive the table update notification
+ * when requested event occurs (registered callback is called). See
+ * function API for more info.
+ * To send custom JSON-RPC request to OVS DB, the `ovs_db_send_request'
+ * function is used. Please note, that connection to OVS DB should be
+ * established otherwise the function will return error.
+ * To verify the liveness of established connection, the OVS DB server
+ * sends echo request to the client with a given interval. The OVS utils
+ * takes care about this request and handles it properly.

- * COPYRIGHT (C) 1986 Gary S. Brown. You may use this program, or
- * code or tables extracted from it, as desired without restriction.
- *
- * First, the polynomial itself and its table of feedback terms. The
- * polynomial is
- * X^32+X^26+X^23+X^22+X^16+X^12+X^11+X^10+X^8+X^7+X^5+X^4+X^2+X^1+X^0
- *
- * Note that we take it "backwards" and put the highest-order term in
- * the lowest-order bit. The X^32 term is "implied"; the LSB is the
- * X^31 term, etc. The X^0 term (usually shown as "+1") results in
- * the MSB being 1
- *
- * Note that the usual hardware shift register implementation, which
- * is what we're using (we're merely optimizing it by doing eight-bit
- * chunks at a time) shifts bits into the lowest-order term. In our
- * implementation, that means shifting towards the right. Why do we
- * do it this way? Because the calculated CRC must be transmitted in
- * order from highest-order term to lowest-order term. UARTs transmit
- * characters in order from LSB to MSB. By storing the CRC this way
- * we hand it to the UART in the order low-byte to high-byte; the UART
- * sends each low-bit to hight-bit; and the result is transmission bit
- * by bit from highest- to lowest-order term without requiring any bit
- * shuffling on our part. Reception works similarly
- *
- * The feedback terms table consists of 256, 32-bit entries. Notes
- *
- * The table can be generated at runtime if desired; code to do so
- * is shown later. It might not be obvious, but the feedback
- * terms simply represent the results of eight shift/xor opera
- * tions for all combinations of data and CRC register values
- *
- * The values must be right-shifted by eight bits by the "updcrc
- * logic; the shift must be unsigned (bring in zeroes). On some
- * hardware you could probably optimize the shift in assembler by
- * using byte-swap instructions

-/**
- * Usage:
- *
- * Define plugin's global pointer variable of type ignorelist_t:
- * ignorelist_t *myconfig_ignore;
- * If you know the state of the global ignore (IgnoreSelected),
- * allocate the variable with:
- * myconfig_ignore = ignorelist_create (YourKnownIgnore);
- * If you do not know the state of the global ignore,
- * initialize the global variable and set the ignore flag later:
- * myconfig_ignore = ignorelist_init ();
- * Append single entries in your cf_register'ed callback function:
- * ignorelist_add (myconfig_ignore, newentry);
- * When you hit the IgnoreSelected config option,
- * offer it to the list:
- * ignorelist_ignore (myconfig_ignore, instantly_got_value_of_ignore);
- * That is all for the ignorelist initialization.
- * Later during read and write (plugin's registered functions) get
- * the information whether this entry would be collected or not:
- * if (ignorelist_match (myconfig_ignore, thisentry))
- * return;

- * matches, the callback passed in `callback' will be called along with the
- * pointer `user_pointer'.
- * The string that's passed to the callback depends on the regular expression:
- * If the regular expression includes a sub-match, i. e. something like
- * "value=([0-9][0-9]*)"
- * then only the submatch (the part in the parenthesis) will be passed to the
- * callback. If there is no submatch, then the entire string is passed to the
- * callback.
- * The optional `excluderegex' allows to exclude the line from the match, if
- * the excluderegex matches.
- * When `match_destroy' is called the `user_data' pointer is freed using
- * the `free_user_data' callback - if it is not NULL.

- * Creates a new `cu_match_t' with a default callback. The user data for that

- * UTILS_MATCH_DS_TYPE_COUNTER_SET

- * UTILS_MATCH_DS_TYPE_COUNTER_ADD

- DESCRIPTION
- The cu_mount_checkoption() function is a replacement of
- char *hasmntopt(const struct mntent *mnt, const char *opt).
- In fact hasmntopt() just looks for the first occurrence of the
- characters at opt in mnt->mnt_opts. cu_mount_checkoption()
- checks for the *option* keyword in line, starting at the
- first character of line or after a ','.

- If full is not 0 then also the end of keyword has to match
- either the end of line or a ',' after keyword.
-
- RETURN VALUE
- The cu_mount_checkoption() function returns a pointer into
- string line if a match of keyword is found. If no match is
- found cu_mount_checkoption() returns NULL.
-
- NOTES
- Do *not* try to free() the pointer which is returned! It is
- just part of the string line.
-
- full should be set to 0 when matching options like: rw, quota,
- noatime. Set full to 1 when matching options like: loop=,
- gid=, commit=.
-
- EXAMPLES
- If line is "rw,usrquota,grpquota", keyword is "quota", NULL
- will be returned (independend of full).
-
- If line is "rw,usrquota,grpquota", keyword is "usrquota",
- a pointer to "usrquota,grpquota" is returned (independend
- of full).
-
- If line is "rw,loop=/dev/loop1,quota", keyword is "loop="
- and full is 0, then a pointer to "loop=/dev/loop1,quota"
- is returned. If full is not 0 then NULL is returned. But
- maybe you might want to try cu_mount_getoptionvalue()...

-char *cu_mount_getoptionvalue(char *line, const char *keyword);
-/*
- DESCRIPTION
- The cu_mount_getoptionvalue() function can be used to grab
- a VALUE out of a mount option (line) like:
- loop=VALUE
- whereas "loop=" is the keyword.
-
- RETURN VALUE
- If the cu_mount_getoptionvalue() function can find the option
- keyword in line, then memory is allocated for the value of
- that option and a pointer to that value is returned.
-
- If the option keyword is not found, cu_mount_getoptionvalue()
- returns NULL;
-
- NOTES
- Internally it calls cu_mount_checkoption(), then it
- allocates memory for VALUE and returns a pointer to that
- string. So *do not forget* to free() the memory returned
- after use!!!

- * Authors:
- * Volodymyr Mytnyk <volodymyrx.mytnyk@intel.com>
- *
- * Description:
- * The OVS util module provides the following features:
- * - Implements the OVS DB communication transport specified
- * by RFC7047:
- * * Connect/disconnect to OVS DB;
- * * Recovery mechanism in case of OVS DB connection lost;
- * * Subscription mechanism to OVS DB table update events
- * (insert/modify/delete);
- * * Send custom JSON request to OVS DB (poll table data, etc.)
- * * Handling of echo request from OVS DB server to verify the
- * liveness of the connection.
- * - Provides YAJL helpers functions.
- *
- * OVS DB API User Guide:
- * All OVS DB function/structure names begins from 'ovs_db_*' prefix. To
- * start using OVS DB API, client (plugin) should initialize the OVS DB
- * object (`ovs_db_t') by calling `ovs_db_init' function. It initializes
- * internal data and creates two main workers (threads). The result of the
- * function is a pointer to new OVS DB object which can be used by other
- * OVS DB API later and must be released by `ovs_db_destroy' function if
- * the object isn't needed anymore.
- * Once OVS DB API is initialized, the `init_cb' callback is called if
- * the connection to OVS DB has been established. This callback is called
- * every time the OVS DB is reconnected. So, if the client registers table
- * update event callbacks or does any other OVS DB setup that can be lost
- * after OVS DB reconnecting, it should be done in `init_cb' callback.
- * The `ovs_db_table_cb_register` function is used to register OVS DB
- * table update event callback and receive the table update notification
- * when requested event occurs (registered callback is called). See
- * function API for more info.
- * To send custom JSON-RPC request to OVS DB, the `ovs_db_send_request'
- * function is used. Please note, that connection to OVS DB should be
- * established otherwise the function will return error.
- * To verify the liveness of established connection, the OVS DB server
- * sends echo request to the client with a given interval. The OVS utils
- * takes care about this request and handles it properly.
