* the problem is described and solved in issue XALANC-744
** https://issues.apache.org/jira/browse/XALANC-744
** so there is no reason for providing a custom patch
|
|
* xalan is segfaulting in XalanDOMString constructor when the static member "XalanLocator::getSystemId" is returning null-pointer
** this should seemingly be handled by passing a pointer to the static constant m_dummy but this sadly fails to prevent the segfault
** the patch provided by this commit fixes the problem for now but I cannot guarantee that this wont cause any side effects in a other context
* Adapted TransformationFacade to handle errors during transformation compilation
** errors generated during transformation compilation are returned through the generate member method
** throwing an exeception during TransformationFacade construction would require additional error handling in the calling code
* Added xalan::ProblemListener functionality to the ErrorHandler class
** XSLT problems passed to the ProblemListener are returned alongside to and treated as all other transformation errors
|
|
* ErrorHandler class created in 5859cb6 now caches all errors instead of pushing them to std::cerr
** cached errors are retrieved by TransformationFacade's "generate" member method
* test frontend pushes all errors to std::cerr
* FunctionTransform returns errors to the calling template as XML
** FunctionTransform test case demonstrates how one may test for successful transformation
* "generate" member method returns std::string vector wrapped in a std::unique_ptr
** this is used as a kind of optional pointer, as the std::unique_ptr instance only wraps a vector if errors where actually generated
|
|
* std::string specialization of "get" template method
* replaces FunctionTransform local input trimming implemented in 5859cb6
|
|
* InputXSLT::ErrorHandler is derived from xercesc::ErrorHandler and enables contextual printing of transformation errors
** currently this means that the error messages passed to std::cerr contain the full path of the offending transformation
* added input trimming to the external transform function
** calls to this function from inside a transformation may contain unnecessary whitespace characters which disrupt further processing
|
|
* verifying type attribute and extension value node if available
|
|
* test case requires markdown.pl formatter to be available in "/usr/bin/"
* updated README.md to mention "external-text-formatter" instead of "execute"
* updated "read-directory" test case reference file
* included library resolution test into "read-file" and "read-xml-file" test cases
|
|
* importing XML output of a called executable into the result document required special logic which clashed with a general execute function
* general execute function may be implemented in the future
** support for external text formatters with XML output has a higher priority
* current implementation enables calling a markdown parser and including the XHTML output into the document
|
|
* enables execution of external programs
** second parameter is passed to stdin
** stdout is captured and returned
** based on booost::process
* this was implemented to enable access to external content preprocessors such as markdown
|
|
* there are situations where one may pass absolute paths to external functions which should not be resolved against the context path
** for example when reading files found by "read-directory" through its "full" value node
* this could be checked by the external functions themself
** but as this check is required by all of them it is better implemented in the FilesystemContext
|
|
* wraps result node construction and appends it to root node on destruction
* offers a simpler interface for common node construction patterns
* simplifies result node construction in all external function implementations
** most noticeable in FunctionReadDirectory
* expanded FunctionReadDirectory result nodes by name, extension, and full-path nodes
|
|
* replaced ranged for loop with more appropriate std::for_each
|
|
* std::vector<FilesystemContext> instance is now const
** this required a constructor change
* marked resolve member method as const as it doesn't need to modify anything
** this is also true for the overloaded resolveEntity member method
** the base class xercesc::EntityResolver prevents us from marking it as such
|
|
* InputXSLT is dependent on boost anyway, so there is no argument to be made to emulate boost::optional using std::pair
|
|
* if a given file can not be located relative to the transformation's location both "read-file" and "read-xml-file" will now try to resolve the path using the IncludeEntityResolver
* all external functions based on the FunctionBase template are now provided with a pointer to a IncludeEntityResolver instance
* it is determined by the external function implementation whether include path resolution will be used
|
|
* enables access to include path resolution from external functions
** this will be useful to enable reading files from the include path using the external read-file or read-xml-file functions
* moved file path extraction into a function local to the compilation unit
|
|
* test case base template contains the basic test case markup
** it was mostly created to include include-path resolution into the test cases
* improved transformer helper template by separating the external function call into its own variable
|
|
* xalan / xerces offers the possibility of implementing custom entity resolvers which are called upon by "<xsl:include..."
** such a custom resolver was implemented to resolve include path entities
* this is a much better way to support include paths than offering a custom external "resolve-include" function
* as entity paths are expanded before they are passed to the entity resolver, a special "[path]" syntax simmilar to "#include <path>" had to be implemented
|
|
* resolves paths provided as strings against include paths provided through the newly created "--include" argument of the test executable
* this was implemented to enable central collections of XSLT libraries simmilar to how there are C headers in "/usr/include"
|
|
* added "std::basic_ostream<char>" taking "generate" member method overloads
* marked cli parameter "target" as optional
** output is streamed to std::cout if target file is not provided
|
|
* added basic "transformer" wrapper template to call "InputXSLT:transform"
** this removes the need to specifiy arguments in a separate xslt variable
|
|
* names matter, from now on parameters to external functions will be called parameters uniformly instead of mixing arguments and parameters
|
|
* the given XObject is passed to the called transformation
** this was done to enable templates to pass information to each other
** this should support any type usable in a XPath context to be passed as an argument
* expanded FunctionTransform test case accordingly
|
|
* FunctionBase::argument_tuple is a std::tuple specialization type specialized on the argument types passed inside the variadic template argument of FunctionBase
* added tuple Mapper and XObjectValue helper namespaces containing recursive tuple construction and XObjectPtr value extraction logic
* changed all external function implementations accordingly
* this change was implemented to uniformly support different external function argument types than std::string
|
|
* external functions may expect arguments with a type different from boost::filesystem::path so they are only provided raw string values
* moved xalan string conversion logic into separate compilation unit
|
|
* constructDocument member method is provided with a FunctionBase::argument_array instance
* improved argument validation in FunctionBase
* this parameter was added to support FunctionBase as a base class for FunctionTransform
|
|
* order of items in a directory was varying across platforms which hindered testability
* they are now temporarily copied into a std::vector instance and then sorted using std::sort
* updated "read_directory" test case reference file accordingly
|
|
* "InputXSLT:transform" expects two input arguments and executes the given transformation into the given target file
** this function respresents a important step in the direction of making it possible to write an actual static site generator on top of InputXSLT using XSLT
* added basic "transform" test case
* updated README.md to include this new function
|
|
* using std::unordered_map for named cache lookups was a nice idea but is not useful when one keeps in mind that:
** we don't want cached external function responses in a situation where we are able to execute transformations inside transformations
** cached responses mean that we can not read a xml file, overwrite it using another transformation and then read it again
* the currently available InputXSLT frontend only processes a single transformation anyway, so increased memory requirements should not pose a problem
** if a future frontend should offer batch processing of transformation tasks, one could implement a cache reset method to free memory after a transformation has been processed
|
|
* fixed compiler flag variable (previous content was deleted)
|
|
* removes responsibility for clearing parameters from the generate member methods
* abstracts parameter escaping and setting and handles map conversion
* marked actual generate member method as private and added StylesheetParameterGuard reference argument
** "frontend" generate member methods instantiate a StylesheetParameterGuard instance and pass it to the actual generate method
** this enables central default parameter definition while offering the possibility for custom parameters
|
|
* the transformation is now provided with default parameters such as the target file and its parent directory
* added appropriate test case
** default_params
* test frontend now doesn't provide a "test" parameter anymore
* extracted parameter setter into separate member method "setParameters" of TransformationFacade
|
|
* as the xerces document is not instantiated by DomDocumentCache::item and the class only exports a pointer to the converted xalan document, it makes no sense to expose the class to the outside in the first place
|
|
* the directories below "./test" contain test cases
** "transformation.xsl" and the expected result as "reference.xml"
** tests are performed by "check.sh"
*** returns diff on error
* this system enables simple verification of external function results
** way simpler than C++ unit tests would be in this scenario
* expanded cmake instructions to automatically execute the test cases
* old example transformation was removed
|
|
* selectively testing document construction in plain C++ code has turned out to be more work than worth it
** i.e. removed test cases and GTest dependency
* added boost::program_options based frontent to InputXSLT
** example command: "./test --transformation ../dummy/transform.xsl --target out.xml"
** the plan is to use a simple shell script that generated test transformations and compares the output to reference files
|
|
* this was needed to share object files between the newly separated test-case and example target executables
* allows for easy development of multiple "frontends" to the same core functionality
|
|
* ... as a test of how well we are able to test DOM structures
* required change of constructDocument visibility
|
|
* common parts were moved into CRTP template base class _FunctionBase_
* all external functions are derived from that class
** only have to implement _constructDocument_ member method
** currently only supports a single string input parameter which is enough for now
* this change condenses external funtion implementations to the essential and should increase readability as well as maintainability
|
|
* this change makes the underlying similarity between all currently implemented external functions obvious
* they more or less only differ in their document construction logic
** i.e. there is a possibility for a second layer of abstraction between the classes derived from xalan::Function and the actual functionality
* added boost::filesystem::path taking overload of the _iterate_ member method to FilesystemGuard
** this overload functions as the _master_ overload that is called by all other overloads which merely perform type conversion and path resolution
** this overload doesn't perform path resolution
|
|
* all instantiations of a FilesystemContext are currently based on information provided by a xalan::Locator instance provided to the external function execute member method
* this change hides the stylesheet path extraction from the actual function implementation
|
|
* DomDocumentCache::item class now is _finalized_ by default and doesn't perform document instantiation, just lifetime management
** xercesc::DOMDocument is instantiated inside the external function implementations and committed to the document cache for conversion to a xalan document
* added mutex with scoped lock to prevent concurrent write access to the std::unordered_map contained withing DomDocumentCache
* functionality of the _get_ member method was split into _get_ and _create_
** added typedef for std::pair specialization type "optional_item" that functions as the return value of _create_ and _get_
* "locator->getSystemId()" was leaking memory as xerces doesn't manage the lifetime of the returned heap-allocated char array
** analog to XMLCh* strings
** transformed XercesStringGuard into template class to be instantiated on either XMLCh or char
|
|
* up until now all external functions were locally installed to a specific XalanTransformer instance contained within a TransformationGuard instance
** this had to change as I planned to add a "execute-transformation" function based on TransformationGuard which would have led to recursive self-instantiation
** global external functions have to be thread-safe
* as global external function can not be provided with a reference to a transformation-specific FilesystemFacade instance, the working path is now determined using xalan::Locator
** currently using pointer arithmetics on XMLCh* to remove the "file://" prefix of the URI returned by locator->getSystemId(), may be unsafe
* added compilation unit for PlattformGuard as it now contains function installation in addition to plattform lifetime management
|
|
* XSLT stylesheets may be provided with a set of initial parameters
** these parameters can be provided as the second argument to the generate member method in the form of a string to string mapping
** the XSLT standard also permitts number and node set types as value arguments of such input parameters but this is not supported by this change
* expanded test transformation to demonstrate this feature
|
|
* "InputXSLT" is defined as "function.inputxslt.application"
* functions can now be accessed like "InputXSLT:read-file('../')"
* updated test transformation accordingly
* the XML standard does not require namespaces to be real, valid HTTP-URIs but treats them as plain strings
|
|
* it was moved into functions local to the respective compilation unit to improve readability
** splits DOM tree construction logic from the actual purpose of the external function
|
|
* all functions return a single "error" node in the case that something went wrong
* otherwise they return one or more "result" nodes that contain the function results and may be distinguished by one or more attributes
* this makes handling the return values easier and more pleasing to the eye as not everything has to be prefixed by "self::*"
* updated test transformation accordingly
|
|
|
|
* throwing std::out_of_range exception from DomDocumentCache::get instead of returning nullptr in case of a problem
* moved xalanToString method back into FilesystemContext compilation unit as is only needed there
|
|
* XML tree is contained below the _content_ node if read was successful
** status is set to error otherwise
* updated test transformation accordingly
|
|
* updated test transformation accordingly
