The function updates the entry in the section page table and updates the section association rmaps for it. In the page-in path, when the new section association is set before the entry is updated, a concurrent attempt to unmap the page would find an inconsistent entry, where there is an rmap, but the section page table entry is still an MM_WAIT_ENTRY.
MmGetSectionAssociation races with _MmSetPageEntrySectionSegment without sharing a lock. So we need to hold the PFN lock, until we have referenced the section segment found in the RMAP. This prevents that a section segment, which still has associated RMAPs from being deleted behind our back.
These are used in the paging path, when the page is currently in the process of being read from or written to the disk. While YieldProcessor() provides the chance to switch context to the other paging thread, it only does so, once the current thread's quantum has expired. On a single CPU system this effectively leads to busy waiting for the rest of the quantum. On SMP systems this could succeed earlier, thus reducing latency, but it would still contribute to high CPU usage, while waiting for the IO operation to complete, which is not what we want.
Using KeDelayExecutionThread() will instantly allow another thread to run, providing enough time to complete the IO operation.
- Implement SHPropertyBag_ReadBSTR, SHPropertyBag_ReadStr, SHPropertyBag_ReadPOINTL,
SHPropertyBag_ReadPOINTS, and SHPropertyBag_ReadRECTL functions.
- Add link to oleaut32 in shlwapi_apitest.

Add a string pointer local variable, assign it and operate on it.
This should eliminate an exception and make LsapIsLocalComputer()
function operate correctly.

Stop storing and setting window positions from the taskbar and rely
on the window's existing position instead. Partial revert of e6bced7a35.
Windows are now correctly positioned when being restored from the taskbar.
This also fixes an issue where minimizing and opening Task Manager causes
the window to become blank when running our shell in Windows Server 2003.
CORE-19055 CORE-13895 CORE-18350
- Add VariantChangeTypeForRead helper function.
- Implement SHPropertyBag_ReadType, SHPropertyBag_ReadBOOL, SHPropertyBag_ReadBOOLOld, SHPropertyBag_ReadSHORT,
SHPropertyBag_ReadLONG, and SHPropertyBag_ReadDWORD functions.
- SHPropertyBag_ReadInt is an alias to SHPropertyBag_ReadLONG.
CORE-9283
- Implement SHPropertyBag_Delete, SHPropertyBag_WritePOINTL, SHPropertyBag_WritePOINTS, and SHPropertyBag_WriteRECTL functions.
- SHPropertyBag_WriteInt is an alias to SHPropertyBag_WriteLONG.
- Modify shlwapi.spec.
- Modify shlwapi_undoc.h.
- Add SHPropertyBag testcase to shlwapi_apitest.exe.
CORE-9283
- Add points regarding real name and e-mail requirements
- Replace old IRC links with the chat references
- Update PR management guidelines accordingly
- Use HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced\TaskbarSmallIcons
registry key to store the icon size setting for the taskbar.
- If the registry value is missing, small icons will be used by default.
- If the registry value is set to 1, it will also use small icons.
- Only if the value exists and is set to 0 it will use large icons. This allows us
to use the same registry value as Windows 7 explorer, while also keeping
the taskbar icons small in most cases, especially running the shell
on unmodified Windows Server 2003.
CORE-11698
- Set `HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\CabinetState\FullPath` to 0 by default.
Adding this registry value also enables the "Display the full path in the title bar" option in our folder options window.
- Query the same registry key when the file explorer is started to determine whether to use the full path or the display name in the window title.
CORE-19046 CORE-18904
- Add Internet icon on Desktop. You can hide/show
the icon from Desktop's customization.
- Modify "HKCR\CLSID\%CLSID_Internet%" registry key.
- Add IDS_INTERNET and IDS_INTERNET_DESCRITION into ieframe.dll.
- Modify folders/CDesktopFolder.cpp and folders/CRegFolder.cpp to add the icon.

This fixes 'Attempt to free an invalid HEAP address' error. CORE-18841
Confirmed by running new tests written by Mark Jansen, showing that
previous behavior was wrong. While here, also fix a typographical error.
New ReactOS can zip/unzip files and folders in UTF-8 filenames.
You can also choose the codepage of filenames to zip/unzip via
the ZipCodePage / UnZipCodePage registry values on the registry
key HKEY_CURRENT_USER\Software\ReactOS.
Windows 8 or later also support UTF-8 zipped folders.
You can also use 3rd party software to zip/unzip in older Windows.
- Use <atlconv.h> for string conversion.
- Use zipOpenNewFileInZip4_64 instead of zipOpenNewFileInZip3_64,
and then add MINIZIP_UTF8_FLAG flag.
- Set the filenames in UTF-8 by using CP_UTF8 codepage.
- Codepage is user selectable via registry settings.

This will be needed for compatibility with x86 Windows Vista/7 videoprt.sys builds.
Might be also useful in future for platforms (x86 , ...) where V86 mode is not available or buggy.

- Add _ILGetDriveType helper function.
- Use _ILGetDrive and GetDriveType functions to determine the drive type.
- If it was a CD-ROM drive, then remove SFGAO_CANRENAME flag.
CORE-18272
- Extend some Ansi strings to Wide strings.
- Check the UTF-8 flag (1 << 11). If UTF-8, then use CP_UTF8.
- s/LPCWSTR/PCWSTR/.

- Use proper window styles when creating status bar window.
- Specify WS_VISIBLE style only when status bar display is enabled.
- Use ::CreateWindowExW() with a global namespace scope operator.
- Fix some magic constants.

The "dir /w" command didn't look good due to unaligned columns.
- Add sdk/include/reactos/cjkcode.h header file.
- Add ConGetTextWidthA/W helper functions.
- Add base/shell/cmd/wcwidth.c to implement ConGetTextWidthW.
- Use ConGetTextWidth in DirPrintWideList function.
- Adjust some STRING_DIR_HELP5, STRING_DIR_HELP6 and STRING_DIR_HELP8 resource strings to make the column aligned.

All ordinals > 128 regressed by

Now all 684 ordinals seem to be fine again.
Adding the stub might cost a few bytes unfortunately.

These caused the "Ignore-next-mouse-event" mechanism of the console
(used e.g. in QuickEdit mode for not triggering the appearance of the
context menu, etc.) to not work.
Please note that these buggy events, that arise when testing ReactOS
in VirtualBox with Mouse Integration is enabled, do not show up when
running instead Windows (2003, ...) in the same configured VM.
Addendum to commits ac51557 (r63792) and 33d8a4b (r67218).
Improved fix for the one reported in PR #5406 by contributor 'whindsaks',
as it keeps the separation between the flag that manages the working-around
of the bug, and the other flag that is used for ignoring the genuine next
mouse event that follows mouse-button-down events.
