vnstat-2.10-bp156.3.7

- Drop vnstat-if.sh, the used options are not supported anymore by
  vnstat and only create error messages

- Update to version 2.10:
  Fixed
  * Image output of 5 minute graph wasn't possible if data
    retention of the 5 minute time period was configured as
    unlimited.
  * Estimates and average rates weren't calculated correctly for
    daily, monthly and yearly time periods when monitoring of the
    interface had been started during the ongoing time period.
  * Estimates weren't being shown in summary output when
    OutputStyle or --style was configured with a value less than 2.
  * Alignment of column header in short output wasn't correct when
    OutputStyle or --style was configured with the value 0 (vnstat)
  New
  * Support input of more than 31 characters in interface name when
    using interface1+interface2 syntax data merge queries.

  * Add Prometheus compatible metrics endpoint cgi to examples.
    (examples/vnstat-metrics.cgi)

- update to 2.9:
  * RescanDatabaseOnSave configuration option wasn't being read from the
    configuration file resulting in the feature always being enabled
  * Hourly graph image output using large fonts didn't correctly fade out
    the x-axis line for hours not having data available
  * Add --alert for producing output and/or specific exit status when
    configured condition and transfer limit is exceeded, can also be used
    for "quota remaining" type of queries depending on used parameters
  * Add configuration option InterfaceMatchMethod which allows configuring
    the possibility of specifying an interface for database queries by using
    its alias instead of system provided interface name, enabled by default
    to support case insensitive matching of the beginning of interface
    aliases (vnstat and vnstati)
  * Image output file extension allows selecting the used image file format
    as long as the used LibGD supports it, PNG is no longer the only option
  * Add configuration option HourlyGraphMode for changing the output mode
    of the graph, 0 = 24 hour sliding window (default, as in previous
    releases), 1 = graph begins from midnight
  * Add mode parameter for -hg / --hoursgraph options for overriding the
    HourlyGraphMode configuration option setting from the command line
  * Add vertical line to image output hourly graph to visualize midnight

    when configured condition and transfer limit is exceeded, can
    also be used for "quota remaining" type of queries depending
    on used parameters.
  * Add configuration option InterfaceMatchMethod which allows
    configuring the possibility of specifying an interface for
    database queries by using its alias instead of system provided
    interface name, enabled by default to support case insensitive
    matching of the beginning of interface aliases (vnstat and
    vnstati).
  * Image output file extension allows selecting the used image
    file format as long as the used LibGD supports it, PNG is no
    longer the only option.
  * Add configuration option HourlyGraphMode for changing the
    output mode of the graph, 0 = 24 hour sliding window (default,
    as in previous releases), 1 = graph begins from midnight.
  * Add mode parameter for -hg / --hoursgraph options for
    overriding the.
  * HourlyGraphMode configuration option setting from the command
    line.

- update to 2.8:
  - Using a combination of --live and --json wasn't flushing stdout after
    each line resulting in buffered output if the output was being piped
  - Image output would fail to show the last line bar graph in list outputs
    if EstimateStyle was 0, BarColumnShowsRate was 1 and the last line had a
    higher traffic rate than other lines
  - Image output didn't correctly horizontally align the "no data available"
    message in 5 minute graph depending on the width of the image
  - Image output related configuration warnings could get shown when image
    output wasn't being used
  - Warnings of mismatches between image output and data retention
    configuration didn't provide relevant details for solving the issues
  - BandwidthDetection was being used for tun interfaces even when the
    Linux kernel had the information hardcoded to 10 Mbit regardless of the
    used real interface, interface specific MaxBW will now be used instead
    or MaxBandwidth as fallback
  - Configured interface specific MaxBW values were getting overridden by
    BandwidthDetection when something could be detected
  - Image output horizontal rx/tx bars often had one pixel too much width in
    the tx section resulting in slightly wrong ratio getting shown
  - Top days list wasn't always sorting entries with exactly the same traffic
    sum using ascending date
  - 64bitInterfaceCounters with value -2 always assumed 32-bit on Linux
    systems until a 64-bit value was seen if kernel headers weren't available
    when binaries were built
  - Add the possibility of specifying an interface without using the
  - i / --iface options (vnstat and vnstati)
  - The daemon can discover added interfaces from the database without
    requiring a restart, configurable with option RescanDatabaseOnSave
  - Add configuration option UseUTC for using UTC as timezone for database
    entries instead of following the system timezone configuration
  - --iflist uses user configured interface specific MaxBW values in the
    output when available instead of showing only the kernel provided
    information when detected
  - Add configuration option AlwaysAddNewInterfaces to expose the daemon
  - -alwaysadd command line option which gains an optional mode parameter
  - Image output uses LibGD filled arc bug workaround only for LibGD
    versions that are known to be broken
  - Image output example cgi (examples/vnstat.cgi) improvements
  - Automatically lists all monitored interfaces instead of requiring the
    list to be filled manually, server name in page title comes from
    hostname command by default
  - Provides links for most available images to more detailed or longer
    versions of each image
  - Allows direct interface specific page access with /interfacename suffix
    for the cgi if the used httpd supports PATH_INFO
  - Page auto refresh can be enabled with configurable interval

- Install examples/systemd/simple/vnstat.service
- Drop not longer needed patch:
  * systemd234.patch

- Update to version 2.7
  Fixed

    database existed but no data was available.
  * ./configure output could show invalid install paths with some
    parameter combinations.

    related parameters for the output of a 5 minute resolution bar
    graph

    LargeFonts for controlling the image output font size.
  * Add --scale and configuration option ImageScale for scaling the
    image output to a given percent.

  * Add --initdb to daemon for creating a new empty database
    without having the daemon process staying running, doesn't
    discard data if a database already exists.
  * Add configuration option BarColumnShowsRate for having the bar
    column in image list outputs be scaled according to the average
    rate column values when those values are visible, disabled by
    default.
  * Add --dbiflist for getting a list of interfaces in the
    database, both --iflist and --dbiflist also get alternative
    more parseable outputs.
  * Add configuration option for large font output and make 5
    minute resolution graph visible in "vnstat.cgi".

- Adapt mod_authz_host parameter instead of deprecated mod_access_compat
  parametere.

  shortcut through the -mini flavors.

- Update to version 2.6
  Fixed
  * --json and --xml didn't support having both mode and limit
    parameters defined at the same time as documented, broken since
    previous release
  * Documentation was using a mix of "count" and "limit" for the
    option of limiting the maximum number of shown entries in
    queries
  * Summary image output would segmentation fault when the database
    existed but didn't yet contain any daily or monthly data for
    the selected interface
  New

    of outputs

- Update to version 2.5
  Fixed
  * Automatic interface selection wasn't done for --traffic and
  - -live when the Interface configuration setting was left empty
  * --setalias didn't do anything when used in combination
    with --add
  * -l / --live and -tr default to first interface instead of
    producing an error if a interface merge is requested

- Update to version 2.4
  Fixed
  * Daemon didn't correctly wait when acquiring database lock for
    data write which could result in unnecessary errors and even
    process exit if an external database read operation had exactly
    the same timing as the daemon write operation
  * Move vnstatd man page from section 1 to section 8
  New
  * Add --rename for renaming interfaces already existing the
    database

- Update to version 2.3
  Fixed
  * Traffic rate wasn't being shown for the last entry of most lists
    during the first update of the next period (first SaveInterval
    minutes of each new hour, day, month and year)
  * Systemd example service file could result in database file write
    issues if the used systemd version supported ProtectSystem=strict
    but didn't support StateDirectory
  * Interfaces could end up staying marked as 'disabled' in the
    database even after becoming back active and monitored, only the
    shown status was wrong without resulting in any data loss
  * Some image outputs didn't allocate enough height for the image
    resulting in the last row having less space below it than intended
  New
  * Automatic interface selection when the Interface configuration
    setting is left empty (new default)
  * Add configuration option DatabaseWriteAheadLogging to enable
    SQLite Write-Ahead Logging mode which may provide some disk i/o

    SQLite setting of the "synchronous" flag, see
    https://www.sqlite.org/pragma.html#pragma_synchronous for more
    details
  * Show warning in log if writing cached data to database is slow
