Author: pschweitzer Date: Sat May 27 17:29:11 2017 New Revision: 74683 URL: http://svn.reactos.org/svn/reactos?rev=74683&view=rev Log: [RDBSS] [RXCE] Try to make use of wrapper more 'properly'. Now, we use wrappers for ASSERT and memory management. This allows us to allocate memory with low priority (which isn't supported by ReactOS yet :-(). Note that we go a bit farther than MS: we also define RxFreePoolWithTag() and make use of it. This should make Thomas happy :-) CORE-11327 Modified: trunk/reactos/sdk/include/ddk/rxovride.h trunk/reactos/sdk/include/ddk/rxpooltg.h trunk/reactos/sdk/lib/drivers/rdbsslib/rdbss.c trunk/reactos/sdk/lib/drivers/rxce/rxce.c Modified: trunk/reactos/sdk/include/ddk/rxovride.h URL: http://svn.reactos.org/svn/reactos/trunk/reactos/sdk/include/ddk/rxovride.h… ============================================================================== --- trunk/reactos/sdk/include/ddk/rxovride.h [iso-8859-1] (original) +++ trunk/reactos/sdk/include/ddk/rxovride.h [iso-8859-1] Sat May 27 17:29:11 2017 @@ -1,3 +1,11 @@ #ifndef NO_RXOVRIDE_GLOBAL #include <struchdr.h> #endif + +#ifndef RX_POOL_WRAPPER +#define RX_POOL_WRAPPER 1 +#endif + +#ifndef RDBSS_ASSERTS +#define RDBSS_ASSERTS 1 +#endif Modified: trunk/reactos/sdk/include/ddk/rxpooltg.h URL: http://svn.reactos.org/svn/reactos/trunk/reactos/sdk/include/ddk/rxpooltg.h… ============================================================================== --- trunk/reactos/sdk/include/ddk/rxpooltg.h [iso-8859-1] (original) +++ trunk/reactos/sdk/include/ddk/rxpooltg.h [iso-8859-1] Sat May 27 17:29:11 2017 @@ -9,5 +9,14 @@ #define RX_WORKQ_POOLTAG ('qWxR') #define RX_MISC_POOLTAG ('sMxR') #define RX_IRPC_POOLTAG ('rIxR') +#ifdef __REACTOS__ +#define RX_TLC_POOLTAG ('??xR') +#endif + +extern ULONG RxExplodePoolTags; + +#define RX_DEFINE_POOLTAG(ExplodedPoolTag, DefaultPoolTag) ((RxExplodePoolTags == 0) ?

Author: pschweitzer Date: Fri May 26 20:52:18 2017 New Revision: 74674 URL: http://svn.reactos.org/svn/reactos?rev=74674&view=rev Log: [RDBSS] [RXCE] [DDK] Add an initial implementation of the RXCE and RDBSS libraries that are used to implement mini-redirectors The associated headers are also added to DDK The implementation is partial (really!) and is only working for read-only operations. It leaks memory as hell (no refcounting implemented) and thus, objects freeing is not implemented. It was tested with NFS41 driver. With such RDBSS, it's possible for the driver to mount a remote share, to list files, to query their properties, to query volume properties, and finally to read files (with some corruption under specific conditions). Please refrain from committing in this (especially for modifying whitespaces or fixing comments...), this is still WIP and under development, it would mess with my local changes! In itself, it doesn't bring anything to ReactOS yet, as no mini redirector is available in ReactOS source tree. This may come later on with NFS41. More to follow...
