+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.)

-I am running Windows 7 and I am finding that the installed driver is not signed. [@efeat]::
+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. [@carlreinke]::
+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].


-Why is the DLL not installed in the Windows system directories? [@netheril96]::
+Case-sensitive file systems do not work properly when mounted as a directory.::
+
+    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? [@netheril96]::
+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? [@efeat]::
+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.

+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.
 +
@ -54,3 +61,12 @@ 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?::
+
+    The core WinFsp layer supports multiple file systems in the same process either simultaneously or one after another. However this is not the case with WinFsp-FUSE (i.e. the FUSE layer of WinFsp).
+
+File systems in Windows often need to be run as services. For this reason the WinFsp-FUSE layer provides both file system and Windows service API functionality. This way a WinFsp-FUSE file system can easily become a Windows service. There is a problem: once a Windows process starts acting as a service and then stops being a service, it cannot become a service again.
+
+Having FUSE file systems being able to act as Windows services is valuable. Therefore this is not a limitation that can easily be fixed as FUSE file systems would lose the "free" ability to act as Windows services.

+WinFsp Launch API.
+
+In order to use the WinFsp Launch API a program must include <winfsp/launch.h>
+and link with the winfsp$$_$$x64.dll (or winfsp$$_$$x86.dll) library.
+
+== Launch Control
+
+=== Functions
+
+*FspLaunchCallLauncherPipe* - Call launcher pipe.
+
+[source,c]
+----
+FSP_API NTSTATUS FspLaunchCallLauncherPipe( 
+    WCHAR Command,
+    ULONG Argc,
+    PWSTR *Argv,
+    ULONG *Argl, 
+    PWSTR Buffer,
+    PULONG PSize,
+    PULONG PLauncherError);  
+----
+
+*Parameters*
+
+- _Command_ - Launcher command to send. For example, the 'L' launcher command instructs
+the launcher to list all running service instances.
+- _Argc_ - Command argument count. May be 0.
+- _Argv_ - Command argument array. May be NULL.
+- _Argl_ - Command argument length array. May be NULL. If this is NULL all command arguments
+are assumed to be NULL-terminated strings. It is also possible for specific arguments
+to be NULL-terminated; in this case pass -1 in the corresponding Argl position.
+- _Buffer_ - Buffer that receives the command response. May be NULL.
+- _PSize_ - Pointer to a ULONG. On input it contains the size of the Buffer. On output it
+contains the number of bytes transferred. May be NULL.
+- _PLauncherError_ - Receives the launcher error if any. This is always a Win32 error code. May not be NULL.
+
+*Return Value*
+
+STATUS$$_$$SUCCESS if the command is sent successfully to the launcher, even if the launcher
+returns an error. Other status codes indicate a communication error. Launcher errors are
+reported through PLauncherError.
+
+*Discussion*
+
+This function is used to send a command to the launcher and receive a response.
+
+
+*FspLaunchGetInfo* - Get information about a service instance.
+
+[source,c]
+----
+FSP_API NTSTATUS FspLaunchGetInfo( 
+    PWSTR ClassName,
+    PWSTR InstanceName, 
+    PWSTR Buffer,
+    PULONG PSize, 
+    PULONG PLauncherError);  
+----
+
+*Parameters*
+
+- _ClassName_ - Class name of the service instance to stop.
+- _InstanceName_ - Instance name of the service instance to stop.
+- _Buffer_ - Buffer that receives the command response. May be NULL.
+- _PSize_ - Pointer to a ULONG. On input it contains the size of the Buffer. On output it
+contains the number of bytes transferred. May be NULL.
+- _PLauncherError_ - Receives the launcher error if any. This is always a Win32 error code. May not be NULL.
+
+*Return Value*
+
+STATUS$$_$$SUCCESS if the command is sent successfully to the launcher, even if the launcher
+returns an error. Other status codes indicate a communication error. Launcher errors are
+reported through PLauncherError.
+
+*Discussion*
+
+The information is a list of NULL-terminated strings: the class name of the service instance,
+the instance name of the service instance and the full command line used to start the service
+instance.
+
+
+*FspLaunchGetNameList* - List service instances.
+
+[source,c]
+----
+FSP_API NTSTATUS FspLaunchGetNameList( 
+    PWSTR Buffer,
+    PULONG PSize, 
+    PULONG PLauncherError);  
+----
+
+*Parameters*
+
+- _Buffer_ - Buffer that receives the command response. May be NULL.
+- _PSize_ - Pointer to a ULONG. On input it contains the size of the Buffer. On output it
+contains the number of bytes transferred. May be NULL.
+- _PLauncherError_ - Receives the launcher error if any. This is always a Win32 error code. May not be NULL.
+
+*Return Value*
+
+STATUS$$_$$SUCCESS if the command is sent successfully to the launcher, even if the launcher
+returns an error. Other status codes indicate a communication error. Launcher errors are
+reported through PLauncherError.
+
+*Discussion*
+
+The information is a list of pairs of NULL-terminated strings. Each pair contains the class
+name and instance name of a service instance. All currently running service instances are
+listed.
+
+
+*FspLaunchStart* - Start a service instance.
+
+[source,c]
+----
+FSP_API NTSTATUS FspLaunchStart( 
+    PWSTR ClassName,
+    PWSTR InstanceName,
+    ULONG Argc,
+    PWSTR *Argv, 
+    BOOLEAN HasSecret, 
+    PULONG PLauncherError);  
+----
+
+*Parameters*
+
+- _ClassName_ - Class name of the service instance to start.
+- _InstanceName_ - Instance name of the service instance to start.
+- _Argc_ - Service instance argument count. May be 0.
+- _Argv_ - Service instance argument array. May be NULL.
+- _HasSecret_ - Whether the last argument in Argv is assumed to be a secret (e.g. password) or not.
+Secrets are passed to service instances through standard input rather than the command
+line.
+- _PLauncherError_ - Receives the launcher error if any. This is always a Win32 error code. May not be NULL.
+
+*Return Value*
+
+STATUS$$_$$SUCCESS if the command is sent successfully to the launcher, even if the launcher
+returns an error. Other status codes indicate a communication error. Launcher errors are
+reported through PLauncherError.
+
+
+*FspLaunchStop* - Stop a service instance.
+
+[source,c]
+----
+FSP_API NTSTATUS FspLaunchStop( 
+    PWSTR ClassName,
+    PWSTR InstanceName, 
+    PULONG PLauncherError);  
+----
+
+*Parameters*
+
+- _ClassName_ - Class name of the service instance to stop.
+- _InstanceName_ - Instance name of the service instance to stop.
+- _PLauncherError_ - Receives the launcher error if any. This is always a Win32 error code. May not be NULL.
+
+*Return Value*
+
+STATUS$$_$$SUCCESS if the command is sent successfully to the launcher, even if the launcher
+returns an error. Other status codes indicate a communication error. Launcher errors are
+reported through PLauncherError.
+
+
+== Service Registry
+
+=== Functions
+
+*FspLaunchRegFreeRecord* - Free a service registry record.
+
+[source,c]
+----
+FSP_API VOID FspLaunchRegFreeRecord( 
+    FSP_LAUNCH_REG_RECORD *Record);

+----
+
+*Parameters*
+
+- _ClassName_ - The service class name.
+- _Agent_ - The name of the agent that is retrieving the service record. This API matches
+the supplied Agent against the Agent in the service record and it only returns
+the record if they match. Pass NULL to match any Agent.
+- _PRecord_ - Pointer to a record pointer. Memory for the service record will be allocated
+and a pointer to it will be stored at this address. This memory must be later
+freed using FspLaunchRegFreeRecord.
+
+*Return Value*
+
+STATUS$$_$$SUCCESS or error code.
+
+*See Also*
+
+- FspLaunchRegFreeRecord
+
+
+*FspLaunchRegSetRecord* - Add/change/delete a service registry record.

-The WinFsp-FUSE layer added support for `struct fuse_stat_ex` in `v1.2B3` which was a potentially breaking change for backwards compatibility. These binaries are used to verify that WinFsp-FUSE remains backwards compatible.

-     * MEMFS stores the whole file system in a single map. This was to keep the file system
-     * "simple", but in retrospect it was probably a bad decision as it creates multiple problems.
-     *
-     * One of these problems was what caused GitHub issue #103. A directory that had both "Firefox"
-     * and "Firefox64" subdirectories in it would cause directory listings of "Firefox" to fail,
-     * because "Firefox\\" (and "Firefox:") comes *after* "Firefox64" in case-sensitive or
-     * case-insensitive order!
-     *
-     * The hackfix is this: copy our input strings into temporary buffers and then translate ':' to
-     * '\x1' and '\\' to '\x2' so they always order the FileName map properly.

Bill Zissimopoulos	a4629b8f8b	sys: fsmup device - This commit introduces the fsmup device, which is a major change in how network file systems are handled. Previously every network file system's fsvol device was directly registered with the MUP. Now there is a single fsmup device that is registered with the MUP; network file systems' fsvol devices register with fsmup instead. The fsmup device maintains a prefix table which it uses to demultiplex and forward requests to the appropriate fsvol device. - This device change was necessatitated to fix issue #87.	2018-01-16 10:38:52 -08:00
