# - Manage data files stored outside source tree
# Use this module to unambiguously reference data files stored outside the
# source tree and fetch them at build time from arbitrary local and remote
# content-addressed locations. Functions provided by this module recognize
# arguments with the syntax "DATA{<name>}" as references to external data,
# replace them with full paths to local copies of those data, and create build
# rules to fetch and update the local copies.
#
# The DATA{} syntax is literal and the <name> is a full or relative path
# within the source tree. The source tree must contain either a real data
# file at <name> or a "content link" at <name><ext> containing a hash of the
# real file using a hash algorithm corresponding to <ext>. For example, the
# argument "DATA{img.png}" may be satisfied by either a real "img.png" file in
# the current source directory or a "img.png.md5" file containing its MD5 sum.
#
# The 'ExternalData_Expand_Arguments' function evaluates DATA{} references
# in its arguments and constructs a new list of arguments:
# ExternalData_Expand_Arguments(
# <target> # Name of data management target
# <outVar> # Output variable
# [args...] # Input arguments, DATA{} allowed
# )
# It replaces each DATA{} reference in an argument with the full path of a
# real data file on disk that will exist after the <target> builds.
#
# The 'ExternalData_Add_Test' function wraps around the CMake add_test()
# command but supports DATA{} references in its arguments:
# ExternalData_Add_Test(
# <target> # Name of data management target
# ... # Arguments of add_test(), DATA{} allowed
# )
# It passes its arguments through ExternalData_Expand_Arguments and then
# invokes add_test() using the results.
#
# The 'ExternalData_Add_Target' function creates a custom target to manage
# local instances of data files stored externally:
# ExternalData_Add_Target(
# <target> # Name of data management target
# )
# It creates custom commands in the target as necessary to make data files
# available for each DATA{} reference previously evaluated by other functions
# provided by this module. A list of URL templates must be provided in the
# variable ExternalData_URL_TEMPLATES using the placeholders "%(algo)" and
# "%(hash)" in each template. Data fetch rules try each URL template in order
# by substituting the hash algorithm name for "%(algo)" and the hash value for
# "%(hash)".
#
# The following hash algorithms are supported:
# %(algo) <ext> Description
# ------- ----- -----------
# MD5 .md5 Message-Digest Algorithm 5, RFC 1321
ExternalData: Add support for SHA 1 and 2 hash algorithms Update the Module.ExternalData and RunCMake.ExternalData tests to cover some of them.

# Note that the hashes are used only for unique data identification and
# download verification. This is not security software.
#
# Example usage:
# include(ExternalData)
# set(ExternalData_URL_TEMPLATES "file:///local/%(algo)/%(hash)"
# "http://data.org/%(algo)/%(hash)")
# ExternalData_Add_Test(MyData
# NAME MyTest
# COMMAND MyExe DATA{MyInput.png}
# )
# ExternalData_Add_Target(MyData)
# When test "MyTest" runs the "DATA{MyInput.png}" argument will be replaced by
# the full path to a real instance of the data file "MyInput.png" on disk. If
# the source tree contains a content link such as "MyInput.png.md5" then the
# "MyData" target creates a real "MyInput.png" in the build tree.
#
ExternalData: Improve series matching using an explicit syntax Automatic series recognition can generate false positives too easily when the default series configuration is flexible enough to handle common cases. Avoid false positives by requiring an explicit syntax to activate series recognition. Choose the syntax DATA{<name>,:} to be short, simple, and look like a vertical ellipsis. This allows us to improve the default series match configuration. Allow series references to contain one of the numbered file names. Allow '-' as a separator in addition to '.' and '_'. Document what the default configuration matches. Also provide more options to configure series <name> parsing.
2013-01-26 01:30:30 +04:00
# The DATA{} syntax can be told to fetch a file series using the form
# "DATA{<name>,:}", where the ":" is literal. If the source tree contains a
# group of files or content links named like a series then a reference to one
# member adds rules to fetch all of them. Although all members of a series
# are fetched, only the file originally named by the DATA{} argument is
# substituted for it. The default configuration recognizes file series names
# ending with "#.ext", "_#.ext", ".#.ext", or "-#.ext" where "#" is a sequence
# of decimal digits and ".ext" is any single extension. Configure it with a
# regex that parses <number> and <suffix> parts from the end of <name>:
# ExternalData_SERIES_PARSE = regex of the form (<number>)(<suffix>)$
# For more complicated cases set:
# ExternalData_SERIES_PARSE = regex with at least two () groups
# ExternalData_SERIES_PARSE_PREFIX = <prefix> regex group number, if any
# ExternalData_SERIES_PARSE_NUMBER = <number> regex group number
# ExternalData_SERIES_PARSE_SUFFIX = <suffix> regex group number
# Configure series number matching with a regex that matches the
# <number> part of series members named <prefix><number><suffix>:
# ExternalData_SERIES_MATCH = regex matching <number> in all series members
# Note that the <suffix> of a series does not include a hash-algorithm
# extension.

#
# The DATA{} syntax can alternatively match files associated with the named
# file and contained in the same directory. Associated files may be specified
# by options using the syntax DATA{<name>,<opt1>,<opt2>,...}. Each option may
# specify one file by name or specify a regular expression to match file names
# using the syntax REGEX:<regex>. For example, the arguments
# DATA{MyData/MyInput.mhd,MyInput.img} # File pair
# DATA{MyData/MyFrames00.png,REGEX:MyFrames[0-9]+\\.png} # Series
# will pass MyInput.mha and MyFrames00.png on the command line but ensure
# that the associated files are present next to them.
#
ExternalData: Allow DATA{} syntax to reference directories Use a trailing slash to reference a directory. Require that a list of associated files be specified to select from within the directory. One may simply use DATA{Dir/,REGEX:.*} to reference all files but get a directory passed on the command line.
2013-01-30 00:12:08 +04:00
# The DATA{} syntax may reference a directory using a trailing slash and a
# list of associated files. The form DATA{<name>/,<opt1>,<opt2>,...} adds
# rules to fetch any files in the directory that match one of the associated
# file options. For example, the argument DATA{MyDataDir/,REGEX:.*} will pass
# the full path to a MyDataDir directory on the command line and ensure that
# the directory contains files corresponding to every file or content link in
# the MyDataDir source directory.

# The variable ExternalData_LINK_CONTENT may be set to the name of a supported
# hash algorithm to enable automatic conversion of real data files referenced
# by the DATA{} syntax into content links. For each such <file> a content
# link named "<file><ext>" is created. The original file is renamed to the
# form ".ExternalData_<algo>_<hash>" to stage it for future transmission to
# one of the locations in the list of URL templates (by means outside the
# scope of this module). The data fetch rule created for the content link
# will use the staged object if it cannot be found using any URL template.
#
# The variable ExternalData_OBJECT_STORES may be set to a list of local
# directories that store objects using the layout <dir>/%(algo)/%(hash).
# These directories will be searched first for a needed object. If the object
# is not available in any store then it will be fetched remotely using the URL
# templates and added to the first local store listed. If no stores are
# specified the default is a location inside the build tree.
#
# The variable ExternalData_SOURCE_ROOT may be set to the highest source
# directory containing any path named by a DATA{} reference. The default is
# CMAKE_SOURCE_DIR. ExternalData_SOURCE_ROOT and CMAKE_SOURCE_DIR must refer
# to directories within a single source distribution (e.g. they come together
# in one tarball).
#
# The variable ExternalData_BINARY_ROOT may be set to the directory to hold
# the real data files named by expanded DATA{} references. The default is
# CMAKE_BINARY_DIR. The directory layout will mirror that of content links
# under ExternalData_SOURCE_ROOT.
#
# Variables ExternalData_TIMEOUT_INACTIVITY and ExternalData_TIMEOUT_ABSOLUTE
# set the download inactivity and absolute timeouts, in seconds. The defaults
# are 60 seconds and 300 seconds, respectively. Set either timeout to 0

ExternalData: Preserve escaped semicolons during argument expansion The CMake language implicitly flattens lists so a ";" in a list element must be escaped with a backslash. List expansion removes backslashes escaping semicolons to leave raw semicolons in the values. Teach ExternalData_Add_Test and ExternalData_Expand_Arguments to re-escape semicolons found in list elements so the resulting argument lists work as if constructed directly by the set() command. For example: ExternalData_Add_Test(Data NAME test1 COMMAND ... "a\\;b") ExternalData_Expand_Arguments(Data args2 "c\\;d") add_test(NAME test2 COMMAND ... ${args2}) should be equivalent to set(args1 "a\\;b") add_test(NAME test1 COMMAND ... ${args1}) set(args2 "c\\;d") add_test(NAME test2 COMMAND ... ${args2}) which is equivalent to add_test(NAME test1 COMMAND ... "a;b") add_test(NAME test2 COMMAND ... "c;d") Note that it is not possible to make ExternalData_Add_Test act exactly like add_test when quoted arguments contain semicolons because the CMake language flattens lists when constructing function ARGN values. This re-escape approach at least allows test arguments to have semicolons. While at it, teach ExternalData APIs to not transform "DATA{...;...}" arguments because the contained semicolons are non-sensical.

ExternalData: Do not re-stage staged object files The ExternalData_LINK_CONTENT option tells ExternalData to convert real data files it finds into content links and to "stage" the original content in a ".ExternalData_<algo>_<hash>" file. However, after a data object has been staged it is possible that a user-provided pattern in the "REGEX:" option will later match the staged object file. We must not process staged object files even when a user pattern matches them. Fix the implementation to not match a staged object file as a normal data file for conversion. Extend the RunCMake.ExternalData test to cover this case.
