/* what you can safely assume about requests to your filesystem
|
|
||||||
*
|
|
||||||
* from: http://sourceforge.net/p/fuse/wiki/FuseInvariants/
|
|
||||||
*
|
|
||||||
* There are a number of assumptions that one can safely make when
|
|
||||||
* implementing a filesystem using fuse. This page should be completed with a
|
|
||||||
* set of such assumptions.
|
|
||||||
*
|
|
||||||
* - All requests are absolute, i.e. all paths begin with "/" and include the
|
|
||||||
* complete path to a file or a directory. Symlinks, "." and ".." are
|
|
||||||
* already resolved.
|
|
||||||
*
|
|
||||||
* - For every request you can get except for "Getattr()", "Read()" and
|
|
||||||
* "Write()", usually for every path argument (both source and destination
|
|
||||||
* for link and rename, but only the source for symlink), you will get a
|
|
||||||
* "Getattr()" request just before the callback.
|
|
||||||
*
|
|
||||||
* For example, suppose I store file names of files in a filesystem also into a
|
|
||||||
* database. To keep data in sync, I would like, for each filesystem operation
|
|
||||||
* that succeeds, to check if the file exists on the database. I just do this in
|
|
||||||
* the "Getattr()" call, since all other calls will be preceded by a getattr.
|
|
||||||
*
|
|
||||||
* - The value of the "st_dev" attribute in the "Getattr()" call are ignored
|
|
||||||
* by fuse and an appropriate anomynous device number is inserted instead.
|
|
||||||
*
|
|
||||||
* - The arguments for every request are already verified as much as
|
|
||||||
* possible. This means that, for example "readdir()" is only called with
|
|
||||||
* an existing directory name, "Readlink()" is only called with an existing
|
|
||||||
* symlink, "Symlink()" is only called if there isn't already another
|
|
||||||
* object with the requested linkname, "read()" and "Write()" are only
|
|
||||||
* called if the file has been opened with the correct flags.
|
|
||||||
*
|
|
||||||
* - The VFS also takes care of avoiding race conditions:
|
|
||||||
*
|
|
||||||
* - while "Unlink()" is running on a specific file, it cannot be interrupted
|
|
||||||
* by a "Chmod()", "Link()" or "Open()" call from a different thread on the
|
|
||||||
* same file.
|
|
||||||
*
|
|
||||||
* - while "Rmdir()" is running, no files can be created in the directory
|
|
||||||
* that "Rmdir()" is acting on.
|
|
||||||
*
|
|
||||||
* - If a request returns invalid values (e.g. in the structure returned by
|
|
||||||
* "Getattr()" or in the link target returned by "Symlink()") or if a
|
|
||||||
* request appears to have failed (e.g. if a "Create()" request succeds but
|
|
||||||
* a subsequent "Getattr()" (that fuse calls automatically) ndicates that
|
|
||||||
* no regular file has been created), the syscall returns EIO to the
|
|
||||||
* caller.

||||||
|
* - All requests are absolute, i.e. all paths begin with "/" and include the
|
||||||
|
* complete path to a file or a directory. Symlinks, "." and ".." are
|
||||||
|
* already resolved.
|
||||||
|
*
|
||||||
|
* - For every request you can get except for "Getattr()", "Read()" and
|
||||||
|
* "Write()", usually for every path argument (both source and destination
|
||||||
|
* for link and rename, but only the source for symlink), you will get a
|
||||||
|
* "Getattr()" request just before the callback.
|
||||||
|
*
|
||||||
|
* For example, suppose I store file names of files in a filesystem also into a
|
||||||
|
* database. To keep data in sync, I would like, for each filesystem operation
|
||||||
|
* that succeeds, to check if the file exists on the database. I just do this in
|
||||||
|
* the "Getattr()" call, since all other calls will be preceded by a getattr.
|
||||||
|
*
|
||||||
|
* - The value of the "st_dev" attribute in the "Getattr()" call are ignored
|
||||||
|
* by fuse and an appropriate anomynous device number is inserted instead.
|
||||||
|
*
|
||||||
|
* - The arguments for every request are already verified as much as
|
||||||
|
* possible. This means that, for example "readdir()" is only called with
|
||||||
|
* an existing directory name, "Readlink()" is only called with an existing
|
||||||
|
* symlink, "Symlink()" is only called if there isn't already another
|
||||||
|
* object with the requested linkname, "read()" and "Write()" are only
|
||||||
|
* called if the file has been opened with the correct flags.
|
||||||
|
*
|
||||||
|
* - The VFS also takes care of avoiding race conditions:
|
||||||
|
*
|
||||||
|
* - while "Unlink()" is running on a specific file, it cannot be interrupted
|
||||||
|
* by a "Chmod()", "Link()" or "Open()" call from a different thread on the
|
||||||
|
* same file.
|
||||||
|
*
|
||||||
|
* - while "Rmdir()" is running, no files can be created in the directory
|
||||||
|
* that "Rmdir()" is acting on.
|
||||||
|
*
|
||||||
|
* - If a request returns invalid values (e.g. in the structure returned by
|
||||||
|
* "Getattr()" or in the link target returned by "Symlink()") or if a
|
||||||
|
* request appears to have failed (e.g. if a "Create()" request succeds but
|
||||||
|
* a subsequent "Getattr()" (that fuse calls automatically) ndicates that
|
||||||
|
* no regular file has been created), the syscall returns EIO to the
|
||||||
|
* caller.
