+v1.4 (2019.1)::
+
+Changes since v1.3:
+
+* FUSE3 API (version 3.2) is now available. The FUSE2 API (version 2.8) also remains supported.
+* New `Control` file system operation allows sending custom control codes to the file system using the Windows `DeviceIoControl` API. FUSE `ioctl` is also supported.
+* New `SetDelete` file system operation can optionally be used instead of `CanDelete`. `SetDelete` or `CanDelete` are used to handle the file "disposition" flag, which determines if a file is marked for deletion. See the relevant documentation for more details.
+* `FlushAndPurgeOnCleanup` has now been added to the .NET API. (GitHub PR #176; thanks @FrKaram.)
+* The Launcher now supports running file systems under the user account that started them. Use `RunAs="."` in the file system registry entry.
+* New sample file system "airfs" contributed by @JohnOberschelp. Airfs is an in-memory file system like Memfs on which it is based on; it has received substantial improvements in how the file name space is maintained and has been modified to use modern C++ techniques by John.
+* New sample file system "passthrough-fuse3" passes all operations to an underlying file system. This file system is built using the FUSE3 API. It builds and runs on both Windows and Cygwin.
+* The FUSE layer now supports multiple file systems within a single process. This is a long standing problem that has been fixed. (GitHub issue #135.)
+* The FSD includes a fix for a Windows problem: that case-sensitive file systems do not work properly when mounted as directories. See FAQ entry #3.
+* The FSD includes a fix for a rare but serious problem. (GitHub issue #177. Thanks @thinkport.)
+* The FSD includes a fix for an incompatibility with DrWeb Antivirus. (GitHub issue #192)
+* The DLL includes a fix for an errorenous `STATUS_ACCESS_DENIED` on read-only directories. (GitHub issue #190. Thanks @alfaunits.)

+
+
+v1.3 (2018.1)::
+
+Changes since v1.2POST1:
+
+* Multiple Launcher changes:
+** New `FspLaunch` API. File systems can be started, stopped, queried and listed using `FspLaunchStart`, `FspLaunchStop`, `FspLaunchGetInfo` and `FspLaunchGetNameList`. The API is available in <winfsp/launch.h>
+** New Launcher registry settings `RunAs` and `WorkDirectory`. `RunAs` allows the laucher to launch a file system process under the service accounts LocalService and NetworkService. `WorkDirectory` can be used to specify the work directory for a newly launched file system process.
+* `FSP_FSCTL_VOLUME_PARAMS::FlushAndPurgeOnCleanup` limits the time that Windows keeps files open after an application has closed them. This purges the cache on the last `CloseHandle`, which is a performance drawback.
+** This is now the default behavior on FUSE. To revert to the previous behavior of keeping files open indefinitely use `-o KeepFileCache`.
+* `FSP_FSCTL_VOLUME_PARAMS` has been extended with fine-grained timeouts: `VolumeInfoTimeout`, `DirInfoTimeout`, `SecurityTimeout`, `StreamInfoTimeout`. Set `FSP_FSCTL_VOLUME_PARAMS::Version == sizeof(FSP_FSCTL_VOLUME_PARAMS)` to access the new fields.
+** New FUSE optons `VolumeInfoTimeout`, `DirInfoTimeout` complement the existing `FileInfoTimeout`.
+* The FSD (File System Driver) and its interaction with the Windows MUP (Multiple UNC Provider) has been changed. In practice this eliminates the delays experienced when right-clicking on a WinFsp-backed network drive in the Windows Explorer. (GitHub issue #87.)
+* The WinFsp network provider is now added first in the provider order list. Previously it was added last. (GitHub PR #131; thanks @felfert.)
+* The WinFsp installer now uses the Wix `Provides` dependency extension to provide a `WinFsp` dependency key. (GitHub PR #129; thanks @felfert.)
+* New FUSE `create_umask` option. (GitHub issue #138.)
+* Fix C++ compilation error for WinFsp-FUSE. (GitHub PR #154; thanks @benrubson.)

+* Fix C++ compilation error for WinFsp-FUSE. (GitHub PR #154; thanks @benrubson.)
+* *NOTE*: Prior v1.3 betas run the MEMFS sample file systems under the LocalService account. This is no longer the case: going forward the MEMFS file systems will be running under the LocalSystem account (as in v1.2POST1).

+
+- The WinFsp Launcher can now be controlled by the new `FspLaunch` API. File systems can be started, stopped, queried and listed using `FspLaunchStart`, `FspLaunchStop`, `FspLaunchGetInfo` and `FspLaunchGetNameList`.
+- The WinFsp launcher now supports new registry settings `RunAs` and `WorkDirectory`. `RunAs` allows the laucher to launch a file system process under the service accounts LocalService and NetworkService. `WorkDirectory` can be used to specify the work directory for a newly launched file system process.

+
+
+v1.2POST1 (2017.2; issue #127)::
+
+Changes since v1.1:
+
+- WinFsp-FUSE now supports BSD flags (Windows file attributes) during `getattr` and `fgetattr`. It also adds the `chflags` operation. BSD flags support requires use of the `FSP_FUSE_CAP_STAT_EX` capability and the new `struct fuse_stat_ex` which includes an `st_flags` field. If the preprocessor macro `FSP_FUSE_USE_STAT_EX` is defined before inclusion of `<fuse.h>` then `struct fuse_stat` will also be defined to include the `st_flags` field.
+- WinFsp-FUSE also adds the following OSXFUSE operations: `setcrtime`, `setchgtime`. These can be used to set the creation (birth) time and change (ctime) time of a file.
+- New `GetDirInfoByName` file system operation adds fast queries of directory info by file name rather than pattern [e.g. `FindFirstFileW(L"foobar", FindData)`]. Tests with fsbench showed that such queries are sped up by an order of magnitude when using `GetDirInfoByName` in MEMFS. Case-sensitive FUSE file systems get this optimization for free. The .NET layer also adds `GetDirInfoByName`.
+- New `FspFileSystemOperationProcessId` API adds support for getting the originating process ID (PID) during `Create`, `Open` and `Rename` calls. FUSE file systems can now access `fuse_context::pid`. The .NET layer also adds `GetOperationProcessId`.
+- New command line tool `fsptool` allows command line access to some WinFsp features.
+- The WinFsp launcher now passes the name of the user who launched the file system as a special parameter %U. This is useful to file systems that use the launcher infrastructure, such as SSHFS-Win. [Please note that in earlier betas the user name was passed as parameter %3; the previous method was insecure and is no longer supported.]

+
+
+v1.1 (2017.1)::
+
+This release brings some major new components and improvements.
+
+- A .NET layer that allows the creation of file systems in managed mode. This is contained in the new `winfsp-msil.dll`. The new .NET layer is being tested with the WinFsp test suites and Microsoft's ifstest.
+- FUSE for Cygwin is now included with the installer.
+- FUSE now has a `-ovolname=VOLNAME` parameter that allows setting the volume label. Thanks @samkelly.
+- A number of other FUSE improvements have been made (see issue #85).
+
+NOTE: The C++ layer included in the v1.1 beta releases is not part of this release as it is still work in progress. It can be found in `inc/winfsp/winfsp.hpp` in the WinFsp source repository.

+
+
+v1.0::
+
+This is the WinFsp 2017 release! :tada:
+
+- The API is now *FROZEN*. Breaking API changes will receive a major version update (`2.0`). Incremental API changes will receive a minor version update (`1.x`).
+- Adds chocolatey package. Try `choco install winfsp` (note: pending approval from chocolatey.org).
+- FUSE `-d` output now always goes to stderr. There is also a new `-oDebugLog=FILE` switch to specify a debug output file.
+- FUSE now provides a default `statfs` implementation if a file system does not provide one.
+- The WinFsp DLL now exports `fuse_*` symbols in addition to the `fsp_fuse_*` symbols. These symbols are for use with programs that use FFI technology such as jnr-fuse and fusepy *ONLY*. They are not supposed to be used by native C/C++ programs. Such programs are supposed to include the `<fuse.h>` headers.
+
+
+v1.0RC3::
+
+This is the WinFsp 2017 Release Candidate 3, which should be the last Release Candidate according to the current plan. This release fixes a major issue with some file systems and includes a few smaller changes:
+
+- Fixes GitHub issue #55. Prior to this fix it was possible for a rogue process (or faulty file system) to crash Windows using WinFsp. For full details read http://www.osronline.com/showthread.cfm?link=282037[this thread].
+- Introduces the `FspFileSystemSetMountPointEx` API, which allows the specification of a security descriptor when mounting over a directory.
+- Introduces the `FspVersion` API, which allows the retrieval of the WinFsp DLL version. Currently this reports `0x00010000` (version `1.0`).
+- Introduces the `FSP_FUSE_CAP_CASE_INSENSITIVE` and `FSP_FUSE_CAP_READDIR_PLUS` WinFsp-FUSE flags. The `FSP_FUSE_CAP_CASE_INSENSITIVE` flag allows a file system to mark itself as case-insensitive. The `FSP_FUSE_CAP_READDIR_PLUS` flag allows a file system to include full `stat` details when responding to the `readdir` operation (thus avoiding extraneous `getattr` calls).
+- When using WinFsp-FUSE over Cygwin, POSIX paths can be used as mountpoints.
+- Fixes GitHub issue #45. Prior to this fix, file systems that do not properly implement `Cleanup` (including FUSE file systems) would at times disallow renaming of directories.
+
+
+v1.0RC2::
+
+This is the WinFsp 2017 Release Candidate 2. Some important changes included below:
+
+- WinFsp is now available under the GPLv3 with a special exception for Free/Libre and Open Source Software.
+- The location of the WinFsp launcher registry entries is now `HKEY_LOCAL_MACHINE\Software\WinFsp\Services`. [On Win64 the actual location is `HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\WinFsp\Services`.] This change was necessary to avoid loss of third party file system registry entries during WinFsp uninstallation. [See GitHub issue #31.]
+- Despite stating in the previous release that the API has been finalized the `ReadDirectory` `FSP_FILE_SYSTEM_INTERFACE` operation has been changed. Extensive testing with multiple file systems has shown that `ReadDirectory` was hard to implement correctly. The new definition should make implementation easier for most file systems. [See GitHub issue #34.]
+- Some API's to facilitate `ReadDirectory` implementation have been added. Look for `FspFileSystem*DirectoryBuffer` symbols.
+- The installer now (optionally) installs a sample file system called "passthrough". This is a simple file system that passes all operations to an underlying file system. There is also a tutorial for this file system (in the doc directory).
+- The installer now (optionally) installs a sample file system called "passthrough-fuse". This file system performs the same function as the "passthrough" file system, but uses the FUSE compatibility layer. It builds and runs on both Windows and Cygwin.
+
+
 v1.0RC1::
 
-This is the first Release Candidate. It has been tested for robustness and correct file system semantics in a variety of scenarios. Some of the more important changes:
+This is the WinFsp 2017 Release Candidate 1. It has been tested extensively in a variety of scenarios for stability and correct file system semantics. Some of the more important changes:
 
 - API has been polished and finalized.
+- Extensively tested against multiple test suites including Microsoft's IfsTest.
+- WinFsp I/O Queues (the fundamental WinFsp IPC mechanism) have been improved to work similar to I/O Completion Ports.
+- Opportunistic locks have been implemented.
+- File system statistics have been implemented.
 - Sharing a (disk) file system over the network is supported.
 - Case insensitive file systems are supported.
 - Directories are supported as mount points.

+</p>
 
-Some of the benefits and features of using WinFsp are listed below:
+## Benefits
 
-* Allows for easy development of file systems in user mode. There are no restrictions on what a process can do in order to implement a file system (other than respond in a timely manner to file system requests).
+### Stability
-* Support for disk and network based file systems.
+
-* Support for NTFS level security and access control.
+WinFsp is very stable. There are no known kernel mode crashes and it does not suffer from resource leaks or similar problems. WinFsp owes this stability to its [Design](doc/WinFsp-Design.asciidoc) and its rigorous [Testing Regime](doc/WinFsp-Testing.asciidoc).
-* Support for memory mapped files, cached files and the NT cache manager.
+
-* Support for file change notifications.
+### Performance
-* Support for file locking.
+
-* Correct NT semantics with respect to file sharing, file deletion and renaming.
+WinFsp outperforms its competition and in many scenarios performs as well as NTFS. Read more about its [Performance](doc/WinFsp-Performance-Testing.asciidoc).

+    <img src="doc/WinFsp-Performance-Testing/rdwr_tests.png" height="300"/>
+</p>
+
+### Compatibility
+
+WinFsp strives for compatibility with NTFS and file system correctness. For the full details see the [Compatibility](doc/NTFS-Compatibility.asciidoc) document.
+
+### Easy to Use
+
+WinFsp has an easy to use but comprehensive API.
+
+* This simple [Tutorial](doc/WinFsp-Tutorial.asciidoc) explains how to build a file system.
+* Consult the [API Reference](http://www.secfs.net/winfsp/apiref/) for native development.
+* Includes .NET layer for managed development. See [src/dotnet](src/dotnet).
+* Includes FUSE 2.8 compatibility layer: [fuse/fuse.h](inc/fuse/fuse.h)
+* Includes FUSE 3.2 compatibility layer: [fuse3/fuse.h](inc/fuse3/fuse.h)
+
+### Other Benefits
+
+* Signed drivers provided on every release.
+* Available under the [GPLv3](License.txt) license with a special exception for Free/Libre and Open Source Software.

 ## Project Organization
 
-WinFsp consists of a kernel mode FSD (File System Driver) and a user mode DLL (Dynamic Link Library). The FSD interfaces with NTOS (the Windows kernel) and handles all interactions necessary to present itself as a file system driver to NTOS. The DLL interfaces with the FSD and presents an easy to use API for creating user mode file systems.

 ## Building and Running
 
 In order to build WinFsp you will need the following:
 
-* Windows 10
 * Visual Studio 2015
 * Windows Driver Kit (WDK) 10
 * [Wix toolset](http://wixtoolset.org)
 
-If you build the driver yourself it will not be signed and Windows will refuse to load it unless you enable "testsigning". You can enable "testsigning" using the command `bcdedit.exe -set testsigning`. For more information see this [document](http://www.secfs.net/winfsp/develop/debug/).
+To fully build WinFsp (including the installer) you must use `tools\build.bat`. By default it builds a Release build, but you can choose either the Debug or Release configuration by using the syntax:
 
-WinFsp is designed to run on Vista and above. It has been tested on the following platforms so far:
+    tools\build.bat CONFIGURATION
+
+If you build the driver yourself it will not be signed and Windows will refuse to load it unless you enable "testsigning". You can enable "testsigning" using the command `bcdedit.exe -set testsigning on`. For more information see this [document](http://www.secfs.net/winfsp/develop/debug/).
+
+WinFsp is designed to run on Windows 7 and above. It has been tested on the following platforms:
 
 * Windows 7 Enterprise
 * Windows 8 Pro
-* Windows 10 Pro
 * Windows Server 2012
+* Windows 10 Pro
+* Windows Server 2016
 
 ## How to Help
 
 I am looking for help in the following areas:
 
 * If you have a file system that runs on FUSE please consider porting it to WinFsp. WinFsp has a native API, but it also has a FUSE (high-level) API.
-* If you are working with a language other than C/C++ (e.g. Delphi, C#, etc.) and you are interested in porting/wrapping WinFsp I would love to hear from you.
+* If you are working with a language other than C/C++ (e.g. Delphi, Java, etc.) and you are interested in porting/wrapping WinFsp I would love to hear from you.
-* There are a number of outstanding issues listed in the [GitHub repository](https://github.com/billziss-gh/winfsp/issues) ~~[BitBucket repository](https://bitbucket.org/billziss/winfsp/issues?status=new&status=open)~~. Many of these require knowledge of Windows kernel-mode and an understanding of the internals of WinFsp so they are not for the faint of heart. If you decide to tackle any of those please coordinate with me as I am actively working on that issue list.

 In all cases I can provide ideas and/or support.

+        <description>
+WinFsp is a set of software components for Windows computers that allows the creation of user mode file systems. In this sense it is similar to FUSE (Filesystem in Userspace), which provides the same functionality on UNIX-like computers.
+
+Some of the benefits of using WinFsp are listed below:
+
+* Very well-tested and stable.
+* Very fast.
+* Strives for compatibility with NTFS.
+* Easy to understand but comprehensive API.
+* FUSE compatibility layer for native Windows and Cygwin.
+* Signed drivers provided on every release.
+* Available under the GPLv3 license with a special exception for Free/Libre and Open Source Software.
+
+To verify installation:
+
+* For 64-bit Windows: `net use m: \\memfs64\share` from the command prompt.
+* For 32-bit Windows: `net use m: \\memfs32\share`
+* For Cygwin: `net use m: '\\memfs64\share'`
+* To delete the drive: `net use m: /delete`

+= Frequently Asked Questions
+
+== General
+
+[qanda]
+
+I am running Windows 7 and I am finding that the installed driver is not signed.::
+
+    Your Windows 7 OS is missing SHA-2 Code Signing Support. You need to install the following security advisory that will rectify the problem:
+    https://technet.microsoft.com/en-us/library/security/3033929.aspx
+
+
+Disconnecting (unmapping) a network drive does not work.::
+
+    You may have Dokany installed. Dokany installs its own Network Provider DLL that unfortunately interferes with the WinFsp handling of network drives. The solution is to change your system's Network Provider order and ensure that the WinFsp Network Provider runs before the Dokany one. Instructions on how to change the Network Provider order can be found in this http://blogs.interfacett.com/changing-the-network-provider-order-in-windows-10[article].
+
+
+Case-sensitive file systems do not work properly when mounted as a directory.::
+
+    This is fixed as of WinFsp 2018.2 B3.
++
+Windows and WinFsp support case-sensitive file systems. These file systems work properly when mounted as a drive. Unfortunately when a file system is mounted as a directory over NTFS, Windows expects it to be case-insensitive and will UPPERCASE many of the file names sent to the file system.
++
+This is an unfortunate but well understood Windows limitation. Case-sensitive file systems should only be mounted as drives.
+
+
+Why is the DLL not installed in the Windows system directories?::
+
+    It is true that this would make it convenient to load the DLL, because the Windows loader looks into the Windows system directories when it loads DLL's. However, in the opinion of the WinFsp author, software that does not ship with the OS should not be installing components in the system directories.
++
+There are a few alternative methods to overcome this problem. WinFsp recommends marking the WinFsp DLL as "delay load" and then using `FspLoad` to dynamically load the DLL during process initialization. For more information see the WinFsp Tutorial.
+
+
+Does WinFsp provide debugging symbols?::
+
+    Public debugging symbols are already included in the installer. You need to install the "Developer" feature; the symbols can be found in the `sym` directory under the WinFsp installation directory.
+
+
+Is there a maximum number of concurrent file systems?::
+
+    WinFsp does not have a hard limit of how many file systems can be created or how many processes can create file systems.
++
+As of the commits required to fix issue #55, there is however a hash table inside the FSD that uses PID's (Process ID's) as keys. This hash table currently expects that in general there will not be more than 50 processes creating file systems. However this is not a hard limit.
+
+
+== FUSE
+
+[qanda]
+
+Which version of FUSE does WinFsp-FUSE support?::
+
+    It supports both the FUSE 2.8 and FUSE 3.2 API's. For the FUSE 2.8 API include `<fuse/fuse.h>`. For the FUSE 3.2 API include `<fuse3/fuse.h>`.
+
+
+FUSE on UNIX systems mounts file systems over an existing directory. When mounting a WinFsp-FUSE file system on a directory, the directory is created and later deleted when the file system goes away. What is the reason for this incompatibility?::
+
+    It would be preferrable if WinFsp-FUSE behaved like FUSE on UNIX in this instance. However there are a number of reasons that this is not the case.
++
+When mounting over directories in Windows, WinFsp-FUSE uses a special construct called a reparse point. Reparse points are a general mechanism for adding special behavior to files and directories. One of the possible reparse points is the "mountpoint" reparse point (often called "junction"), which converts a directory into a mount point.
++
+With this in mind here are the reasons for the current WinFsp-FUSE behavior:
++
+- Symmetry with mounting on a drive. On Windows drives are created when the file system comes into existence and deleted when it is gone.
+- Inability to mount over a non-empty directory on Windows. On FUSE/UNIX this is possible, but not on Windows because NTFS disallows the creation of (mountpoint) reparse points on non-empty directories.
+- Most importantly: inability to guarantee that the mount point will cease to exist if the file system crashes. WinFsp attempts to guarantee that all resources used by a file system will get cleaned up. This is certainly true for the kernel-mode FSD, but an attempt is made to do so also in user mode. For this reason, drive symbolic links are marked as temporary and (importantly for our discussion) mount directories are opened with `FILE_FLAG_DELETE_ON_CLOSE`. There is no way to guarantee the removal of a reparse point in the same way.
+
+
+WinFsp-FUSE does not have the ability to support multiple file systems from within the same process. Why?::
+
+    This is supported as of WinFsp 2018.2 B2.
++
+The core WinFsp layer always supported multiple file systems in the same process either simultaneously or one after another. However this was not the case with WinFsp-FUSE (i.e. the FUSE layer of WinFsp) prior to version 2018.2 B2. This limitation has been rectified as of WinFsp 2018.2 B2.

+# WinFsp - Windows File System Proxy
+
+[[WinFsp-Icon.png]]
+
+Developing file systems is a challenging proposition. Developing file systems for Windows is an order of magnitude more difficult. WinFsp eases the task of writing a new file system for Windows. WinFsp file systems are user mode programs and they can be written in a variety of languages and frameworks.
+
+The documentation available here discusses various aspects of WinFsp.
+
+## Programming
+
+- The [[Tutorial|WinFsp-Tutorial]] describes how to create a simple, but complete file system in C/C++.
+- The [[API Reference|WinFsp-API-winfsp.h]] describes the native WinFsp API. This external [[link|http://www.secfs.net/winfsp/apiref/]] may be easier to browse for some people.
+- There is also a FUSE compatibility layer for native Windows and Cygwin. See fuse.h in the source repository.
+- This [[document|Native-API-vs-FUSE]] discusses the need for both a native API and FUSE and gives some pointers on which one to choose.
+
+## Design
+
+- The [[Design|WinFsp-Design]] document describes the high-level design of WinFsp.
+- The [[IPC|WinFsp-as-an-IPC-Mechanism]] document offers insights into the WinFsp Inter-Process Communication mechanism.
+- The [[Queued Events|Queued-Events]] document discusses a low-level synchronization primitive that is largely responsible for the excellent performance of the WinFsp IPC mechanism.
+- The [[Service Architecture|WinFsp-Service-Architecture]] document discusses how to intergrate a file system into Windows as a service and the reasons to do so.
+- The [[SSHFS Port Case Study|SSHFS-Port-Case-Study]] document chronicles the creation of the WinFsp-FUSE compatibility layer and the decisions that led to its design.
+
+## Testing
+
+- The [[Testing|WinFsp-Testing]] document discusses the WinFsp testing strategy and how WinFsp achieves correctness and stability.
+- The [[Performance|WinFsp-Performance-Testing]] document compares WinFsp performance against other file systems.
+
+## Compatibility
+
+- The [[Compatibility|NTFS-Compatibility]] document discusses current WinFsp compatibility with NTFS.
+
+WinFsp is available under the GPLv3 license with a special exception for Free/Libre and Open Source Software.

+= NTFS Compatibility
+
+WinFsp enables the creation of user mode file systems that behave similar to NTFS or FAT. Generic Windows applications that access files on a WinFsp file system cannot and should not be able to determine that it is not a native Windows file system. However specialized applications that access NTFS or FAT specific extensions (such as Defrag) will not work properly on WinFsp file systems.
+
+== Supported features
+
+WinFsp supports the following NTFS features:
+
+- Query and set volume information.
+- Open, create, close, delete files and directories.
+- Query and set file and directory information.
+- Query and set security information (ACL's).
+- Read and write files.
+- Memory mapped I/O.
+- Directory change notifications.
+- Lock and unlock files.
+- Opportunistic locks.
+- Open, create, close, delete, query named streams.
+- Reparse points with special support for symbolic links.
+
+== Unsupported features
+
+WinFsp does not support the following NTFS features:
+
+- Hard links. Rather rarely used on Windows. However it might be worthwhile to implement them for WinFsp.
+- Extended attributes. Although popular with POSIX file systems, they are severely hampered and rarely used on Windows. They are also not exposed via the Win32 API.
+- Short file names. Short file names are a relic of the past. WinFsp made a conscious decision not to support them.
+- Paging files. Providing paging file support via a user mode file system is impossible for a number of reasons.
+- Object ID's. Opening files by ID (+FILE_OPEN_BY_FILE_ID+) is not supported.
+- Volume access. Volume handles can be opened and closed, but volumes cannot be read or written. Such an operation makes little sense for most user mode file systems, that do not store information on disks.
+- Sparse files. A user mode file system is free to implement sparse files. However WinFsp does not support any sparse file related FSCTL or information class codes.
+- Compressed files. A user mode file system is free to implement compressed files. However WinFsp does not support any compression related FSCTL or information class codes.
+- Encrypted files. A user mode file system is free to implement encrypted files. However WinFsp does not support any encryption related FSCTL or information class codes.
+- Quotas.
+- The Change Journal.
+- Defragmentation support.
+
+== Incompatibilities
+
+This section lists incompatibilites with NTFS in those features that they both support:
+
+- WinFsp supports case sensitive and case insensitive file systems. However it does not support case sensitive lookups on a case insensitive file system (+SL_CASE_SENSITIVE+).
+- NTFS updates the file size information in the directory entry when a file is cleaned up. WinFsp file systems do not (and probably should not attempt to) replicate this behavior. [Related article: https://blogs.msdn.microsoft.com/oldnewthing/20111226-00/?p=8813]
+- NTFS supports change notifications on streams (these are mostly undocumented). WinFsp supports them as well but it differs from NTFS in that it issues a single notification when a file with streams is deleted; NTFS appears to issue one notification per deleted stream.
+- WinFsp does not support renaming a stream.
+- NTFS allows for enumeration and change notifications of all reparse points by opening a special NTFS-only "directory" that "contains" all reparse points (+\$Extend\$Reparse:$R:$INDEX_ALLOCATION+). WinFsp does not support this feature.

+= Queued Events - Windows kernel events with IOCP scheduling characteristics
+
+In this article I am discussing _Queued Events_. _Queued Events_ are a Windows kernel synchronization mechanism that I invented for https://github.com/billziss-gh/winfsp[WinFsp - FUSE for Windows]. _Queued Events_ behave like kernel Synchronization Events (i.e. Win32 auto-reset events), but provide scheduling characteristics similar to those of I/O Completion Ports.
+
+== The Problem
+
+During the later stages of WinFsp development I decided to do some performance testing to understand its behavior and find opportunities for optimization. I found out that WinFsp performed very well in most tested scenarios, but there was one test that seemed to have bad performance for no particular reason.
+
+I ended up profiling this issue using xperf (included in the https://docs.microsoft.com/en-us/windows-hardware/test/wpt/[Windows Performance Toolkit]), which allows for kernel-level profiling. I spent considerable time looking at the profiling results, but could identify no obvious issue with my code.
+
+After a day or two of doing this and being stumped I finally had a lightbulb moment: what if the issue is not with my code, but with how the OS schedules threads? Sure enough I had xperf trace context switches and found that on good runs the OS would context switch my file system threads relatively rarely; on bad runs the OS would context switch my threads excessively.
+
+After contemplating this issue I realized that this was happening because the OS was trying to schedule my threads in a "fair" manner. Windows in general tries to give every thread a chance to run. This can be counter-productive in server-like programs (such as file systems), where all server threads are equivalent and it is actually better to reuse the same thread (if possible) to avoid context switching and other negative effects.
+
+== The Solution
+
+One way of looking at WinFsp is as an IPC (Inter-Process Communication) mechanism. The Windows kernel packages file system operations (open, close, read, write) as IRP's (I/O Request Packets) which it sends to WinFsp. WinFsp places them in an _I/O Queue_; at a later time the threads in a user mode file system retrieve the IRP's from the _I/O Queue_ and service them.
+
+The _I/O Queue_ had gone through multiple iterations, but at the time I was looking at this issue it was using Windows kernel Synchronization Event's (Win32 auto-reset events) for managing threads. The problem was that a wait on a Synchronization Event would be satisfied in a "fair" manner, thus resulting to excessive context switching and bad performance in some circumstances. I needed to find a way to convince Windows to schedule my threads in an "unfair" manner, giving preference to the same thread as much as possible.
+
+I started considering different schemes where I would associate a different event per thread thus being able to wake up the "correct" thread myself and effectively writing my own mini-scheduler. Luckily I had another lightbulb moment: I/O completion ports already do this better than I would ever be able to!
+
+The kernel portion of an I/O Completion Port is called a https://msdn.microsoft.com/en-us/library/windows/hardware/ff549547(v=vs.85).aspx[KQUEUE]. KQUEUE's are (unfortunately) not directly exposed to user mode, however they are at the core of the user mode I/O Completion Ports. KQUEUE's are the main reason I/O Completion Ports are so fast as they provide the following scheduling characteristics:
+
+- They have a Last-In First-Out (LIFO) wait discipline.
+- They limit the number of threads that can be satisfied concurrently.
+
+I briefly considered the idea of building _I/O Queues_ directly on top of KQUEUE's, but soon dismissed this idea because _I/O Queues_ are not simple queues but provide additional services, such as IRP cancelation, IRP expiration, etc.
+
+== Queued Events
+
+In an ideal scenario I wanted to continue using my implementation of _I/O Queues_ which had undergone considerable testing and I knew it worked. But somehow I had to convince the Windows kernel to change the scheduling characteristics of Synchronization Events to mirror those of a KQUEUE.
+
+Then I had lightbulb no 3: _Queued Events_ or how to make a queue behave like a Synchronization Event.
+
+Here is how _Queued Events_ work. A _Queued Event_ consists of a KQUEUE and a spin lock. There is also a single dummy item that can be placed in the KQUEUE.
+
+The KQUEUE is guaranteed to contain either 0 or 1 items. When the KQUEUE contains 0 items the _Queued Event_ is considered non-signaled. When the KQUEUE contains 1 items the _Queued Event_ is considered signaled.

+To transition from the non-signaled to the signaled state, we acquire the spin lock and then insert the dummy item in the KQUEUE using https://msdn.microsoft.com/en-us/library/windows/hardware/ff549570(v=vs.85).aspx[KeInsertQueue]. To transition from the signaled to the non-signaled state, we simply (wait and) remove the dummy item from the KQUEUE using https://msdn.microsoft.com/en-us/library/windows/hardware/ff549605(v=vs.85).aspx[KeRemoveQueue] (without the use of the spin lock).

+EventWait:
+    KeRemoveQueue();                 // (wait and) remove item
+----
+
+First notice that EventSet is serialized by the use of the spin lock. This guarantees that the dummy item can be only inserted ONCE in the KQUEUE and that the only possible signaled state transitions for EventSet are 0->1 and 1->1. This is how https://msdn.microsoft.com/en-us/library/windows/hardware/ff553253(v=vs.85).aspx[KeSetEvent] works for a Synchronization Event.
+
+Second notice that EventWait is not protected by the spin lock, which means that it can happen at any time including concurrently with EventSet or another EventWait. Notice also that for EventWait the only possible transitions are 1->0 or 0->0 (0->block->0). This is how https://msdn.microsoft.com/en-us/library/windows/hardware/ff553350(v=vs.85).aspx[KeWaitForSingleObject] works for a Synchronization Event.

+
+We now have to consider what happens when we have one EventSet concurrently with one or more EventWait's:
+
+1. The EventWait(s) happen before https://msdn.microsoft.com/en-us/library/windows/hardware/ff549591(v=vs.85).aspx[KeReadState]. If the KQUEUE has an item one EventWait gets satisfied, otherwise it blocks. In this case KeReadState will read the KQUEUE's state as 0 and KeInsertQueue will insert the dummy item, which will unblock the EventWait.
+2. The EventWait(s) happen after KeReadState, but before KeInsertQueue. If the dummy item was already in the KQUEUE the KeReadState test will fail and KeInsertQueue will not be executed, but EventWait will be satisfied immediately. If the dummy item was not in the KQUEUE the KeReadState will succeed and EventWait will momentarily block until KeInsertQueue releases it.
+3. The EventWait(s) happen after KeInsertQueue. In this case the dummy item in is the KQUEUE already and one EventWait will be satisfied immediately.
+
+NOTE: _Queued Events_ cannot cleanly support an EventClear operation. The obvious choice of using KeRemoveQueue with a 0 timeout is insufficient because it would associate the current thread with the KQUEUE and that is not desirable. KeRundownQueue cannot be used either because it disassociates all threads from the KQUEUE.
+
+The complete implementation of _Queued Events_ within WinFsp can be found here: https://github.com/billziss-gh/winfsp/blob/v1.1/src/sys/driver.h#L655-L795
+
+== Queued Events Scheduling Characteristics
+
+Queued Events encapsulate KQUEUE's and therefore inherit their scheduling characteristics:
+
+- They have a Last-In First-Out (LIFO) wait discipline.
+- They limit the number of threads that can be satisfied concurrently.
+
+These characteristics are desirable because they reduce the number of context switches thus speeding up the WinFsp IPC implementation. Performance testing immediately after the incorporation of _Queued Events_ into WinFsp showed significant performance improvements; profiling with xperf showed that context switches among file system threads were now a relatively rare event!

 WinFsp includes a Network Provider that integrates with Windows and can be used to start and stop user mode file systems from the Windows shell. To achieve this the Network Provider (implemented as part of the WinFsp DLL) works closely with the WinFsp.Launcher service.
 
-For example, if a user uses the Windows Explorer to map `\\memfs64\share` to the `Z:` drive, the Network Provider will instruct the WinFsp.Launcher to start an instance of the memfs64 service with command line `-u \\memfs64\share -m Z:`. When the user disconnects the `Z:` drive, the Network Provider will instruct the WinFsp.Launcher to stop the previously started instance of the memfs64 service.
+For example, if a user uses the Windows Explorer to map `\\memfs64\share` to the `Z:` drive, the Network Provider will instruct the WinFsp.Launcher to start an instance of the memfs64 service with command line `-i -F NTFS -n 65536 -s 67108864 -u \\memfs64\share -m Z:`. When the user disconnects the `Z:` drive, the Network Provider will instruct the WinFsp.Launcher to stop the previously started instance of the memfs64 service.
+
+== File System Credential Support
+
+Some file systems require credentials in order to allow access and be mounted. Such file systems must add a registry value `Credentials`:
+
+    "Credentials"=dword:00000001
+
+This will instruct the WinFsp Network Provider to request a password from the user prior to starting the file system. This password will then be securely passed to the WinFsp Launcher which in turn will pass it to the user mode file system on its standard input. The user mode file system must respond `OK` if the password is correct and allows access to the user mode file system. Any other response from the user mode file system (including a timeout without a response) is interpreted as an authentication failure.
+
+NOTE: During password entry the user may also choose to "remember" the password in which case it will be saved in the Windows Credential Manager.

+WinFsp allows the creation of user mode file systems that exhibit behavior similar to NTFS.

+== Backwards Compatibility testing
+
+As the WinFsp API's mature it is important to verify that they remain backwards compatible with existing file system binaries. For this purpose binaries that have been compiled against earlier versions of WinFsp are used to verify that they run correctly against the latest version.
+
+For example, in version v1.2B3 of WinFsp an +FSP_FUSE_CAP_STAT_EX+ FUSE extension was introduced. This can change the layout of +struct fuse_stat+ and is therefore a potentially dangerous change. To test against inadvertent breakage a FUSE file system binary that was compiled against v1.2B2 is regularly used to verify backwards compatibility.

 == Code Analysis
 
 WinFsp is regularly run under the Visual Studio's Code Analyzer. Any issues found are examined and if necessary acted upon.
