* Make -o clone_fd into a parameter of session_loop_mt().Gravatar Nikolaus Rath2016-10-13
| | | | | | This option really affects the behavior of the session loop, not the low-level interface. Therefore, it does not belong in the fuse_session object.
* Move session options into sub-structGravatar Nikolaus Rath2016-10-13
| | | | | | | The session options are used only once to determine the proper conn->want flags. It is nice to have them clearly separated from the other struct fuse_session members that are used throughout the life of the file system.
* Use NULL for option processing function where possible.Gravatar Nikolaus Rath2016-10-13
|
* Activate splice_read by default if write_buf is implemented.Gravatar Nikolaus Rath2016-10-13
|
* do_init(): treat command line options consistentlyGravatar Nikolaus Rath2016-10-13
| | | | | | | Previously, some command line options would change the FUSE defaults but leave the final value to the file systems `init` handler while others would override any changes made by `init`. Now, command line options do both: they modify the default, *and* take precedence.
* Factored out LL_OPTIONS macroGravatar Nikolaus Rath2016-10-10
|
* Removed 'async_read' field in fuse_conn_infoGravatar Nikolaus Rath2016-10-10
| | | | This is redundant with the capability flags in `wants` and `capable`.
* Make several -o NN options work againGravatar Nikolaus Rath2016-10-10
| | | | | In commit 2ed7af, we accidentally set the default values *after* parsing the command line arguments.
* Use "se" instead of "f" for fuse_session pointer where possible.Gravatar Nikolaus Rath2016-10-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | These changes were generated with the following Coccinelle semantic patch: @@ symbol f, se; // avoid unneeded warnings from Coccinelle @@ struct fuse_session * -f +se ; <... -f +se ...> @@ identifier fn; @@ fn(...,struct fuse_session * -f +se ,...) { <... -f +se ...> }
* fuse_main(): extend support for printing helpGravatar Nikolaus Rath2016-10-10
| | | | | | There's now a way to inhibit the "usage" line (which actually got lost in commit 225c12aebf2d), which makes it easier for simply file-systems to generate good-looking --help output.
* fuse_main_real(): use fuse_parse_cmdline().Gravatar Nikolaus Rath2016-10-09

* fuse_parse_cmdline(): do not print help/version textGravatar Nikolaus Rath2016-10-09
| | | | | The current behavior makes it difficult to add help for additional options. With the change, this becomes a lot easier.
* Added missing export of fuse_pkgversion.Gravatar Nikolaus Rath2016-10-09
|
* Fix valgrind warningGravatar Nikolaus Rath2016-10-09
| | | | | If we don't assign a value to padding, we get a warning about reading uninitialized data when sending the iovec to the kernel.
* Removed ``-o big_writes`` optionGravatar Nikolaus Rath2016-10-08
| | | | | | This option is obsolete and should always be enabled. File systems that want to limit the size of write requests should use the ``-o max_write=<N>`` option instead.
* Remove pointless aliasing of fuse_session *se to *fGravatar Nikolaus Rath2016-10-05
| | | | This is an overlooked artifact of the fuse_ll-fuse_session merge.
* Removed obsolete, unused *f member from struct fuse_session.Gravatar Nikolaus Rath2016-10-05

* Merge fuse_ll into fuse_session (part 8)Gravatar Nikolaus Rath2016-10-04
| | | | Replaced "req->se" with "f" where the latter is already defined.
* Merge fuse_ll into fuse_session (part 7)Gravatar Nikolaus Rath2016-10-04
| | | | | Remove pointless aliasing of "struct fuse_session *se" to "struct fuse_session *f".

* Merge fuse_ll into fuse_session (part 1)Gravatar Nikolaus Rath2016-10-04
| | | | | Merged the structures, and replaced fuse_ll with fuse_session in all type definitions.
* fuse_mount_help(): clarify that listed options are FUSE specificGravatar Nikolaus Rath2016-10-04
| | | | | We also accept a number of mount options that are common to all file systems (nosuid, nodev, ro, etc).
* Clarified purpose of helper.c, moved *version() to fuse.cGravatar Nikolaus Rath2016-10-04

* Merge master fuse_chan into fuse_session.Gravatar Nikolaus Rath2016-10-03
| | | | | | | | | | | | | | | | | | This is a code simplification patch. - It confines most of the implementation channel implementation into fuse_loop_mt (which is its only user). - It makes it more obvious in the code that channels are only ever used when using -o clone_fd and multi-threaded main loop. - It simplies the definition of both struct fuse_session and struct fuse_chan. - Theoretically it should result in (minuscule) performance improvements when not using -o clone_fd. - Overall, it removes a lot more lines of source code than it adds :-).
* fuse_lowlevel_notify_poll(): use master channelGravatar Nikolaus Rath2016-10-03
| | | | | | | | | | | | | | | | In theory, a poll handle could hang around much longer than the worker thread that creates it. Furthermore, the thread that created the pollhandle is no more likely to call fuse_lowlevel_notify_poll() than any other thread. In theory, this would have kept the channel alive for much longer than necessary. In practice, there seems to have been a bug that prevented this - and instead allowed the channel to be destroyed while there was still a pollhandle referring to it. Instead of fixing this by calling fuse_chan_get() and fuse_chan_put() in do_poll() and fuse_pollhandle_destroy(), we simply transmit poll notifications over the master channel now.
* Store struct fuse_session* in struct fuse_reqGravatar Nikolaus Rath2016-10-03

* Released 3.0.0pre0Gravatar Nikolaus Rath2016-10-03

* Added fuse_session_fd()Gravatar Nikolaus Rath2016-10-02
| | | | Fixes #59.
* Merged fuse_session.c into fuse_lowlevel.cGravatar Nikolaus Rath2016-10-02
| | | | | | This distinction no longer makes sens. fuse_lowlevel.c already contains several session related functions, and fuse_session.c contains various stuff that is more related to the channel interface.
* Merged fuse_mt.c into fuse.cGravatar Nikolaus Rath2016-10-02
| | | | There is no point in having a separate file for a 10 line function.
* Extended per-file comments.Gravatar Nikolaus Rath2016-10-02
| | | | | This should make more clear what file contains code for what purpose.
* Don't handle --help and --version in fuse_session_new().Gravatar Nikolaus Rath2016-10-02
| | | | | | | | | | | | | | | | | | | Help and version messages can be generated using the new fuse_lowlevel_help(), fuse_lowlevel_version(), fuse_mount_help(), and fuse_mount_version() functions. The fuse_parse_cmdline() function has been made more powerful to do this automatically, and is now explicitly intended only for low-level API users. This is a code simplication patch. We don't have to parse for --help and --version in quite as many places, and we no longer have a low-level initialization function be responsible for the (super-high level) task of printing a program usage message. In the high-level API, we can now handle the command line parsing earlier and avoid running other initialization code if we're just going to abort later on.
* fuse_mount_opts: don't keep max_read= option.Gravatar Nikolaus Rath2016-10-02
| | | | There is no consumer of it down the line.
* Add section headings for --help outputGravatar Nikolaus Rath2016-10-02
| | | | Also, do not include "General options" in usage message.
* Turn struct fuse_chan into an implementation detailGravatar Nikolaus Rath2016-10-02
| | | | | | | | | | | | | | | | | | | | | The only struct fuse_chan that's accessible to the user application is the "master" channel that is returned by fuse_mount and stored in struct fuse_session. When using the multi-threaded main loop with the "clone_fd" option, each worker thread gets its own struct fuse_chan. However, none of these are available to the user application, nor do they hold references to struct fuse_session (the pointer is always null). Therefore, any presence of struct fuse_chan can be removed without loss of functionality by relying on struct fuse_session instead. This reduces the number of API functions and removes a potential source of confusion (since the new API no longer looks as if it might be possible to add multiple channels to one session, or to share one channel between multiple sessions). Fixes issue #17.

* fuse_lowlevel_notify_*: take struct fuse_session instead of struct fuse_chanGravatar Nikolaus Rath2016-09-27
| | | | | | | | | | | The only struct fuse_chan that's available to the user application is the one that is returned by fuse_mount. However, this is also permanently available from struct fuse_session. A later patch will therefore remove struct fuse_chan from the public API completely. This patch prepares for this by changing the fuse_lowlevel_notify_* functions to take a struct fuse_session parameter instead of a struct fuse_chan parameter.
* Dropped fuse_unmount_compat22Gravatar Nikolaus Rath2016-09-27
| | | | | This function was for backwards compatibility in FUSE 2.x, and is no longer exposed by FUSE 3.

* libfuse/fuse_daemonize: wait until daemon child process is ready (#55)Gravatar Hendrik Brueckner2016-06-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Mounting a FUSE file system remotely using SSH in combination with pseudo-terminal allocation (-t), results in "Transport endpoint is not connected" errors when trying to access the file system contents. For example: # ssh -t root@localhost "cmsfs-fuse /dev/disk/by-path/ccw-0.0.0190 /CMSFS" Connection to localhost closed. # ls /CMSFS ls: cannot access '/CMSFS': Transport endpoint is not connected The cmsfs-fuse main program (which can also be any other FUSE file system) calls into the fuse_main() libfuse library function. The fuse_main() function later calls fuse_daemonize() to fork the daemon process to handle the FUSE file system I/O. The fuse_daemonize() function calls fork() as usual. The child proceeds with setsid() and then redirecting its file descriptors to /dev/null etc. The parent process, simply exits. The child's functions and the parent's exit creates a subtle race. This is seen with an SSH connection. The SSH command above calls cmsfs-fuse on an allocated pseudo-terminal device (-t option). If the parent exits, SSH receives the command completion and closes the connection, that means, it closes the master side of the pseudo-terminal. This causes a HUP signal being sent to the process group on the pseudo-terminal. At this point in time, the child might not have completed the setsid() call and, hence, becomes terminated. Note that fuse daemon sets up its signal handlers after fuse_daemonize() has completed. Even if the child has the chance to disassociate from its parent process group to become it's own process group with setsid(), the child still has the pseudo-terminal opened as stdin, stdout, and stderr. So the pseudo-terminal still behave as controlling terminal and might cause a SIGHUP at closing the the master side. To solve the problem, the parent has to wait until the child (the fuse daemon process) has completed its processing, that means, has become its own process group with setsid() and closed any file descriptors pointing to the pseudo-terminal.
