04/09: [SETUPLIB] Add a new module "bldrsup.c" (WIP) where I place all the NT boot loaders (i.e. ntldr, freeldr, and possibly bootmgr in the future) management functions.

So far we only have: - a function FindNTOSBootLoader() that detects the existence of a given boot loader; - a function EnumerateNTOSBootEntries() (and corresponding helpers) that enumerate the different boot entries in the configuration file(s) for a given boot loader, and for each entry, calls a user-provided callback. Only supported at the moment: ntldr and freeldr. Doing that allows me to simplify large portions of the NT-OS detection code so that it becomes more bootloader-agnostic, and this will help me for simplifying some parts of usetup/bootsup.c too, later... svn path=/branches/setup_improvements/; revision=74661 --- base/setup/lib/CMakeLists.txt | 1 + base/setup/lib/bldrsup.c | 352 ++++++++++++++++++++++++++++ base/setup/lib/bldrsup.h | 59 +++++ base/setup/lib/osdetect.c | 523 ++++++++++++------------------------------ 4 files changed, 556 insertions(+), 379 deletions(-) diff --git a/base/setup/lib/CMakeLists.txt b/base/setup/lib/CMakeLists.txt index 6d687deb1a..819ecf34bd 100644 --- a/base/setup/lib/CMakeLists.txt +++ b/base/setup/lib/CMakeLists.txt @@ -1,6 +1,7 @@ list(APPEND SOURCE arcname.c + bldrsup.c filesup.c fsutil.c genlist.c diff --git a/base/setup/lib/bldrsup.c b/base/setup/lib/bldrsup.c new file mode 100644 index 0000000000..493c52237e --- /dev/null +++ b/base/setup/lib/bldrsup.c @@ -0,0 +1,352 @@ +/* + * PROJECT: ReactOS Setup Library + * LICENSE: GPL-2.0+ (https://spdx.org/licenses/GPL-2.0+) + * PURPOSE: NT 5.x family (MS Windows <= 2003, and ReactOS) + * boot loaders management. + * COPYRIGHT: Copyright 2017-2018 Hermes Belusca-Maito + */ + +// TODO: Add support for NT 6.x family!

Now only exactly 5 calls use the "old" 'DoesFileExist' syntax, using a temporarily auxiliary function "DoesFileExist_2"... svn path=/branches/setup_improvements/; revision=74641 --- base/setup/lib/filesup.c | 45 +++++++------ base/setup/lib/filesup.h | 8 ++- base/setup/lib/osdetect.c | 160 ++++++++++++++++++++------------------------ base/setup/usetup/bootsup.c | 14 ++-- base/setup/usetup/usetup.c | 2 +- 5 files changed, 110 insertions(+), 119 deletions(-) diff --git a/base/setup/lib/filesup.c b/base/setup/lib/filesup.c index 290c4cb414..5a9ba0082c 100644 --- a/base/setup/lib/filesup.c +++ b/base/setup/lib/filesup.c @@ -154,7 +154,7 @@ DoesPathExist( if (NT_SUCCESS(Status)) NtClose(FileHandle); else - DPRINT1("Failed to open directory %wZ, Status 0x%08lx\n", &Name, Status); + DPRINT1("Failed to open directory '%wZ', Status 0x%08lx\n", &Name, Status); return NT_SUCCESS(Status); } @@ -162,21 +162,18 @@ DoesPathExist( BOOLEAN DoesFileExist( IN HANDLE RootDirectory OPTIONAL, - IN PCWSTR PathName OPTIONAL, - IN PCWSTR FileName) + IN PCWSTR PathNameToFile) { NTSTATUS Status; + UNICODE_STRING FileName; HANDLE FileHandle; OBJECT_ATTRIBUTES ObjectAttributes; IO_STATUS_BLOCK IoStatusBlock; - UNICODE_STRING Name; - WCHAR FullName[MAX_PATH]; - CombinePaths(FullName, ARRAYSIZE(FullName), 2, PathName, FileName); - RtlInitUnicodeString(&Name, FullName); + RtlInitUnicodeString(&FileName, PathNameToFile); InitializeObjectAttributes(&ObjectAttributes, - &Name, + &FileName, OBJ_CASE_INSENSITIVE, RootDirectory, NULL); @@ -190,11 +187,22 @@ DoesFileExist( if (NT_SUCCESS(Status)) NtClose(FileHandle); else - DPRINT1("Failed to open file %wZ, Status 0x%08lx\n", &Name, Status); + DPRINT1("Failed to open file '%wZ', Status 0x%08lx\n", &FileName, Status); return NT_SUCCESS(Status); } +// FIXME: DEPRECATED!

This allows building concatenated paths with an arbitrary number of separated components. - Use the newly-introduced CombinePaths() and ConcatPaths() functions. - Fix also few comments, and place some UNICODE_NULLs here & there. svn path=/branches/setup_improvements/;

- Move the inicache library to setuplib as it'll be used for the 1st stage GUI setup too (indeed, there is no good INI file API under Win32; the Win32 profile "API" is just good enough to manipulate the win16 ini files, and are here anyways for backward compatibility purposes only); - Move the OS detector too. - Remove the duplicated ConcatPaths() code in arcname.c. svn path=/branches/setup_improvements/; revision=74634 svn path=/branches/setup_improvements/; revision=74638 --- base/setup/lib/CMakeLists.txt | 3 + base/setup/lib/arcname.c | 136 +++++------- base/setup/lib/filesup.c | 372 +++++++++++++++++++++++++++++++++ base/setup/lib/filesup.h | 57 ++++++ base/setup/{usetup => lib}/inicache.c | 31 +-- base/setup/{usetup => lib}/inicache.h | 27 +-- base/setup/{usetup => lib}/osdetect.c | 15 +- base/setup/{usetup => lib}/osdetect.h | 4 + base/setup/lib/precomp.h | 5 +- base/setup/lib/setuplib.h | 3 + base/setup/usetup/CMakeLists.txt | 2 - base/setup/usetup/filesup.c | 375 +--------------------------------- base/setup/usetup/filesup.h | 57 ------ base/setup/usetup/usetup.h | 2 - 14 files changed, 520 insertions(+), 569 deletions(-) diff --git a/base/setup/lib/CMakeLists.txt b/base/setup/lib/CMakeLists.txt index a37be9d1fb..6d687deb1a 100644 --- a/base/setup/lib/CMakeLists.txt +++ b/base/setup/lib/CMakeLists.txt @@ -1,9 +1,12 @@ list(APPEND SOURCE arcname.c + filesup.c fsutil.c genlist.c + inicache.c ntverrsrc.c + osdetect.c partlist.c precomp.h) diff --git a/base/setup/lib/arcname.c b/base/setup/lib/arcname.c index 60af00dbb1..f40b79173e 100644 --- a/base/setup/lib/arcname.c +++ b/base/setup/lib/arcname.c @@ -23,6 +23,7 @@ #include "precomp.h" +#include "filesup.h" #include "partlist.h" #include "arcname.h" @@ -114,7 +115,7 @@ ArcGetNextTokenA( OUT PANSI_STRING TokenSpecifier, OUT PULONG Key) { - HRESULT hr;
