# - Find the Boost includes and libraries.
# The following variables are set if Boost is found. If Boost is not
# found, Boost_FOUND is set to false.
# Boost_FOUND - True when the Boost include directory is found.
# Boost_INCLUDE_DIRS - the path to where the boost include files are.
# Boost_LIBRARY_DIRS - The path to where the boost library files are.
# Boost_LIB_DIAGNOSTIC_DEFINITIONS - Only set if using Windows.
# Boost_<library>_FOUND - True if the Boost <library> is found.
# Boost_<library>_INCLUDE_DIRS - The include path for Boost <library>.
# Boost_<library>_LIBRARIES - The libraries to link to to use Boost <library>.
# Boost_LIBRARIES - The libraries to link to to use all Boost libraries.
#
# The following variables can be set to configure how Boost is found:
# Boost_LIB_PREFIX - Look for Boost libraries prefixed with this, e.g. "lib"
# Boost_LIB_SUFFIX - Look for Boost libraries ending with this, e.g. "vc80-mt"
# Boost_LIB_SUFFIX_DEBUG - As for Boost_LIB_SUFFIX but for debug builds, e.g. "vs80-mt-gd"
# ----------------------------------------------------------------------------
# If you have installed Boost in a non-standard location or you have
# just staged the boost files using bjam then you have three
# options. In the following comments, it is assumed that <Your Path>
# points to the root directory of the include directory of Boost. e.g
# If you have put boost in C:\development\Boost then <Your Path> is
# "C:/development/Boost" and in this directory there will be two
# directories called "include" and "lib".
# 1) After CMake runs, set Boost_INCLUDE_DIR to <Your Path>/include/boost<-version>
# 2) Use CMAKE_INCLUDE_PATH to set a path to <Your Path>/include. This will allow FIND_PATH()
# to locate Boost_INCLUDE_DIR by utilizing the PATH_SUFFIXES option. e.g.
# SET(CMAKE_INCLUDE_PATH ${CMAKE_INCLUDE_PATH} "<Your Path>/include")
# 3) Set an environment variable called ${BOOST_ROOT} that points to the root of where you have
# installed Boost, e.g. <Your Path>. It is assumed that there is at least a subdirectory called
# include in this path.
#
# Note:
# 1) If you are just using the boost headers, then you do not need to use
# Boost_LIBRARY_DIRS in your CMakeLists.txt file.
# 2) If Boost has not been installed, then when setting Boost_LIBRARY_DIRS
# the script will look for /lib first and, if this fails, then for /stage/lib.
#
# Usage:
# In your CMakeLists.txt file do something like this:
# ...
# # Boost
# FIND_PACKAGE(Boost)
# ...
# INCLUDE_DIRECTORIES(${Boost_INCLUDE_DIRS})
# LINK_DIRECTORIES(${Boost_LIBRARY_DIRS})
#
# In Windows, we make the assumption that, if the Boost files are installed, the default directory
# will be C:\boost.
#
# TODO:
#
# 1) Automatically find the Boost library files and eliminate the need
# to use Link Directories.
#
IF(WIN32)
# In windows, automatic linking is performed, so you do not have to specify the libraries.
# If you are linking to a dynamic runtime, then you can choose to link to either a static or a
# dynamic Boost library, the default is to do a static link. You can alter this for a specific
# library "whatever" by defining BOOST_WHATEVER_DYN_LINK to force Boost library "whatever" to
# be linked dynamically. Alternatively you can force all Boost libraries to dynamic link by
# defining BOOST_ALL_DYN_LINK.
# This feature can be disabled for Boost library "whatever" by defining BOOST_WHATEVER_NO_LIB,
# or for all of Boost by defining BOOST_ALL_NO_LIB.
# If you want to observe which libraries are being linked against then defining
# BOOST_LIB_DIAGNOSTIC will cause the auto-linking code to emit a #pragma message each time
# a library is selected for linking.

/***************************************************************************
* gswap.c:
*
* Functions for generalized, in-pace byte swapping between LSBF and
* MSBF byte orders.
*
* Some standard integer types are needed, namely uint8_t and
* uint32_t, (these are normally declared by including inttypes.h or
* stdint.h). Each function expects it's input to be a void pointer
* to a quantity of the appropriate size.
*
* There are two versions of most routines, one that works on
* quantities regardless of alignment (gswapX) and one that works on
* memory aligned quantities (gswapXa). The memory aligned versions
* (gswapXa) are much faster than the other versions (gswapX), but the
* memory *must* be aligned.
*
* Written by Chad Trabant,
* IRIS Data Management Center

# Change Log
All notable changes to the CAPS client library will be documented in this file.
## 2021-04-21 1.0.0
### Changed
- Set library version to 1.0.0
## 2021-02-16
### Added
- Allow to set maximum allowed future end time via plugin API. In additon
add commandline and config support to the plugin application class e.g.
```
output.maxFutureEndTime = 120
```
By default the option is set to 120 seconds.
## 2020-12-14
### Added
- Support to set miniSEED record length via API
## 2020-09-22
### Changed
- Use last sample time as reference time for maximum future time check. Before
we used the packet end time as reference time but this makes no sense in case
of low sampled data.
- So far we used the current time as start time if journal entries exceeded the
maximum allowed future time. With this release we use the journal time no
matter what its value but display a warning when the journal time is more than
one day in the future.
## 2020-06-22
### Added
- Python3 byte array support to any record push
## 2020-02-21
### Changed
- Increase default timeout for acknowledgement messages from 5s to 60s
## 2019-09-24
### Fixed
- Fix high load if packets could not be sent to CAPS. In that case the plugin
automatically reconnects after some amount of time. If triggered under certain
circumstances this delay was not in effect and caused unnecessarily high
amount of connection attempts. Under some circumstances the plugin could have
crashed due to a stack overflow.
- The quit method has now the semantics to continue pushing packets as long
as the connection is established and only abort in case of an error without
attempting a reconnect.
## 2019-09-20
### Fixed
- Fix error string if not all data could be sent to the server
## 2019-08-19
### Changed
- Discard packets whose end time is more than 120 seconds before the system time.
## 2019-08-06
### Added
- new config option ``output.addr``
### Fixed
- ambiguous command line option ``-h``. With this version of the library the
host and port can be set via the command line option ``--addr``.
- wrong config option parsing
## 2019-08-05
### Fixed
- seg fault in date time parser
## 2019-08-02
### Fixed
- Hanging TCP connections. In case of the remote side does not shutdown cleanly
the plugin did not notice that the connection is no longer available. With this
version the plugin reconnects to the server when the TCP send buffer is full and
tries to send all not acknowledged packets again.
- Do not discard packets if the packet buffer is full. Instead we block until
the server acknowledges some packets.
### Changed
- The plugin application class checks whether the configured buffer size is
below the minimum.
## 2019-07-05
### Changed
- Ignore journal entries where the timestamp is more than 10 seconds
before the system time.
## 2018-12-19
### Fixed
- Read journal from file in plugin application.
## 2018-12-18
### Fixed
- Do not reconnect if the plugin buffer is full. Instead of we try to read
acknowledgements from the CAPS server until the plugin buffer is below the
threshold.
## 2018-12-17
### Added
- Support to retrieve status information e.g. the number of buffered bytes from
plugin.
## 2018-09-06
### Changed
- Enable more verbose logging for MSEED packets
## 2018-07-25
### Fixed
- unset variable of the raw data record
- trim function will return false in case of an unknown datatype
## 2018-05-30
### Fixed
- Fixed unexpected closed SSL connections
## 2018-06-05
### Fixed
- Fix RawDataRecord::setHeader
## 2018-05-16
### Fixed
- RAW data end time calculation
## 2018-03-19
### Added
- SSL support
## 2017-11-20
### Added
- float and double support for Steim encoders. All values will be converted implicitly
to int 32 values
## 2017-11-08
### Added
- timing quality parameter to push call. By default the timing quality is set to -1.
## 2017-11-07
### Fixed
- do not flush encoders after reconnect
## 2017-10-26
### Added
- SSL support
## 2017-10-24
### Fixed
- packet synchronization error after reconnect
