From db31b6dfa9c8fe37d5706d95ce81012b8db3c3b9 Mon Sep 17 00:00:00 2001 From: Even Rouault Date: Wed, 22 Jan 2020 18:31:26 +0100 Subject: Merge RFC4 (#1865) This commit is the result of the squashing of rfc4_dev branch in a single commit. It implements mostly RFC 4 related work. * Grid handling: - remove obsolete and presumably unfinished implementation of grid catalog functionality - all grid functionality is in grids.cpp/.hpp - vertical and horizontal grid shift: rework to no longer load whole grid into memory - remove hgrids and vgrids member from PJ structure, and store them in hgridshift/vgridshift/deformation structures - build systems: add optional libtiff dependency. Must be explicitly disabled if not desired - add support for horizontal and vertical grids in GeoTIFF, if libtiff is available - add GenericShiftGridSet and GenericShiftGrid classes, relying on TIFF grids, that can be used for generic purpose grid-based adjustment - add a +proj=xyzgridshift method to perform geocentric translation by grid. Used for French NTF to RGF93 transformation using gr3df97a.tif grid - deformation: add support for +grids= for GeoTIFF grids - horizontal grid shift: fix failures on points slightly outside a subgrid (fixes #209) * File management: - add a filemanager.cpp/.hpp to deal with file related work - test for legacy proj_api.h fileapi - proj.h: add proj_context_set_fileapi() and proj_context_set_sqlite3_vfs_name() (fixes #866) - add capability to read resource files from the user writable directory * Network access: - build systems: add optional curl dependency - add a curl-based default implementation for network related functionality - proj.h: add C API to control network functionality, and optionaly provide network callbacks - add data/proj.ini with default settings - add a SQLite3 local cache of downloaded chunks - add proj_is_download_needed() and proj_download_file() * Use Win32 Unicode APIs and expect all strings to be UTF-8 (fixes #1765) For backward compatibility, if PROJ_LIB content is found to be not UTF-8 or pointing to a non existing directory, then an attempt at interpretating it in the ANSI page encoding is done. proj_context_set_search_paths() now assumes strings to be in UTF-8, and functions returning paths will also return values in UTF-8. --- src/ctx.cpp | 36 +++++++----------------------------- 1 file changed, 7 insertions(+), 29 deletions(-) (limited to 'src/ctx.cpp') diff --git a/src/ctx.cpp b/src/ctx.cpp index bcb6e1cc..6172b3c8 100644 --- a/src/ctx.cpp +++ b/src/ctx.cpp @@ -33,6 +33,7 @@ #include "proj_experimental.h" #include "proj_internal.h" +#include "filemanager.hpp" /************************************************************************/ /* pj_get_ctx() */ @@ -60,9 +61,9 @@ void pj_set_ctx( projPJ pj, projCtx ctx ) if (pj==nullptr) return; pj->ctx = ctx; - if( pj->is_pipeline ) + if( pj->reassign_context ) { - pj_pipeline_assign_context_to_steps(pj, ctx); + pj->reassign_context(pj, ctx); } for( const auto &alt: pj->alternativeCoordinateOperations ) { @@ -95,7 +96,8 @@ projCtx_t projCtx_t::createDefault() projCtx_t ctx; ctx.debug_level = PJ_LOG_NONE; ctx.logger = pj_stderr_logger; - ctx.fileapi = pj_get_default_fileapi(); + ctx.fileapi_legacy = pj_get_default_fileapi(); + NS_PROJ::FileManager::fillDefaultNetworkInterface(&ctx); if( getenv("PROJ_DEBUG") != nullptr ) { @@ -133,12 +135,13 @@ projCtx_t::projCtx_t(const projCtx_t& other) debug_level = other.debug_level; logger = other.logger; logger_app_data = other.logger_app_data; - fileapi = other.fileapi; + fileapi_legacy = other.fileapi_legacy; epsg_file_exists = other.epsg_file_exists; set_search_paths(other.search_paths); file_finder = other.file_finder; file_finder_legacy = other.file_finder_legacy; file_finder_user_data = other.file_finder_user_data; + networking = other.networking; } /************************************************************************/ @@ -258,28 +261,3 @@ void *pj_ctx_get_app_data( projCtx ctx ) return nullptr; return ctx->logger_app_data; } - -/************************************************************************/ -/* pj_ctx_set_fileapi() */ -/************************************************************************/ - -void pj_ctx_set_fileapi( projCtx ctx, projFileAPI *fileapi ) - -{ - if (nullptr==ctx) - return; - ctx->fileapi = fileapi; -} - -/************************************************************************/ -/* pj_ctx_get_fileapi() */ -/************************************************************************/ - -projFileAPI *pj_ctx_get_fileapi( projCtx ctx ) - -{ - if (nullptr==ctx) - return nullptr; - return ctx->fileapi; -} - -- cgit v1.2.3
