4605 5658 d 1 h decky /branches/snapshot/ add task snapshoting branch  
4586 5661 d 20 h jermar /trunk/uspace/ Add libfs_stat() and let FAT and TMPFS use it.  
4585 5661 d 20 h jermar /trunk/uspace/ Introduce VFS_IN_FSTAT and VFS_OUT_STAT.
Provide libc fstat() and devfs_stat().
This functionality replaces VFS_IN_NODE
and VFS_IN/OUT_DEVICE. FAT and TMPFS
still do not implement this and VFS_IN_STAT
and stat() need implementation as well.		  
4509 5682 d 1 h decky /trunk/uspace/ rename libadt -> adt  
4465 5686 d 20 h decky /trunk/uspace/srv/fs/ implement VFS_OPEN_NODE and VFS_DEVICE (no device handle is returned)
implement no-op VFS_SYNC and VFS_CLOSE		  
4429 5698 d 20 h jermar /trunk/uspace/ Add fs_handle argument to libfs_mount() needed to recognize homogenous mounts.  
4424 5699 d 20 h jermar /trunk/uspace/srv/fs/tmpfs/ Call libfs_mount() from tmpfs_mount().  
4409 5701 d 17 h jermar /trunk/uspace/ Rudimentary support for non-root mounts.  
4370 5711 d 17 h jermar /trunk/uspace/ Streamline TMPFS and fix its design so that it properly supports hardlinks.
libfs operation unlink() is now passed also the name of the component being
unlinked.		  
4357 5715 d 17 h jermar /trunk/uspace/ Introduce the concept of FS nodes. A FS node is a typed abstraction of
file-system-specific node type. It replaces the void * in libfs interfaces
and is suitable for holding various information such as mount point data.		  
4306 5732 d 19 h jermar /trunk/uspace/srv/fs/tmpfs/ Support multiple TMPFS instances.  
4305 5732 d 23 h jermar /trunk/uspace/ Support mount options.
Let tmpfs decide whether to start empty or restored a TMPFS dump based on the mount option.		  
4268 5741 d 7 h svoboda /trunk/uspace/ str_cpy() and str_ncpy() in userspace. Nuke strcpy() and strncpy().  
4264 5741 d 18 h svoboda /trunk/uspace/ Nuke strcpy() and strcmp().  
3625 5879 d 2 h jermar /trunk/uspace/ libfs operation link() should return standard error code instead of mere
true/false.		  
3575 5892 d 17 h jermar /trunk/uspace/ libfs create operation should take the device handle as argument.  
3352 5971 d 19 h jermar /trunk/uspace/srv/ Add reference to the mounted FS root.

This makes it possible to keep the FS root logically unlinked (i.e. lnkcnt == 0)
because it prevents VFS from attempting to destroy it during closedir().		  
3109 6049 d 0 h jermar /trunk/uspace/srv/ Split the 'mount another filesystem here' and 'you are being mounted and the
device is this' mount semantics. Add VFS_MOUNTED VFS operation that corresponds
to the latter and reserve VFS_MOUNT only for the former. Because of this
change, the VFS server does not maintain the mr_node VFS node for the name space
root anymore and the VFS_LOOKUP operation is now not meant to be used on
unmounted file system, not even for looking up the root node of unmounted file
systems. In the light of these changes, TMPFS is now initialized from
tmpfs_mounted() function.		  
3103 6049 d 16 h jermar /trunk/uspace/srv/fs/tmpfs/ Evict the code which loads the TMPFS file system from a file system dump to a
dedicated source file.		  
3091 6051 d 19 h jermar /trunk/uspace/srv/fs/tmpfs/ Return value argument to ipc_call_sync_X_Y() may not be int or it will
break on 64-machines that are sensitive to unaligned memory accesses.
Moreover, overcasting int * to sysarg_t * is not a good idea either
even if the int is by chance aligned on a 64-bit boundary as some
unknown memory will get overwritten during the assignment. Change the
type of the retval argument to ipcarg_t.		  
3087 6052 d 0 h decky /trunk/uspace/srv/fs/tmpfs/ initialize tmpfs from RAM disk  
2958 6067 d 17 h jermar /trunk/uspace/srv/ Make VFS_MOUNT call even when mounting the root file system.  
2863 6096 d 3 h jermar /trunk/uspace/ Revert libfs node_get() API to a model without the parent node pointer
argument.		  
2858 6101 d 12 h jermar /trunk/uspace/ libfs destroy operation should rather return an error code instead of a truth
value.		  
2857 6101 d 12 h jermar /trunk/uspace/ Add stubs for unimplemented FAT libfs operations.  
2852 6102 d 10 h jermar /trunk/uspace/ Add node_put() to libfs operations and instrument libfs_lookup() to use it at
appropriate places.
Add node_put() to libfs operations and instrument libfs_lookup() to use it at
appropriate places.
Add node_put() to libfs operations and instrument libfs_lookup() to use it at
appropriate places.
Add node_put() to libfs operations and instrument libfs_lookup() to use it at
appropriate places.
Add node_put() to libfs operations and instrument libfs_lookup() to use it at
appropriate places.
Add node_put() to libfs operations and instrument libfs_lookup() to use it at
appropriate places.		  
2844 6103 d 16 h jermar /trunk/uspace/ Add fat_root_get() and fat_plb_get_char().  
2831 6106 d 10 h jermar /trunk/uspace/ Commit progress on the FAT file system server implementation.  
2792 6113 d 19 h jermar /trunk/uspace/ libfs' node_get() operation does not need the file system handle.  
2791 6116 d 16 h jermar /trunk/uspace/ Make libfs_lookup() more generic.  
2770 6135 d 18 h jermar /trunk/uspace/ Introduce fs_handle_t, dev_handle_t and fs_index_t.  
2763 6137 d 22 h jermar /trunk/uspace/ Support for rename().  
2760 6140 d 16 h jermar /trunk/uspace/ Support for multiple TMPFS node names.  
2758 6141 d 17 h jermar /trunk/uspace/ No need to keep the parent pointer in the TMPFS node. Moreover, other file
systems won't have it either. Finally, if TMPFS is to support hardlinks, there
can be multiple parents.		  
2757 6141 d 18 h jermar /trunk/uspace/srv/fs/tmpfs/ Set the TMPFS root node's link count to 1.  
2756 6141 d 19 h jermar /trunk/uspace/srv/fs/tmpfs/ Introduce real link counts for TMPFS.  
2747 6148 d 16 h jermar /trunk/uspace/ Move the core lookup logic from TMPFS to libfs.  
2742 6150 d 16 h jermar /trunk/uspace/srv/ Separate creation of a TMPFS node and its linking in the file system name space.
Rename VFS_FREE to VFS_DESTROY and destroy_node() to unlink_node().		  
2739 6156 d 17 h jermar /trunk/uspace/srv/fs/tmpfs/ Remove duplicate initialization.  
2736 6158 d 19 h jermar /trunk/uspace/srv/fs/tmpfs/ Unlink a TMPFS node more thoroughly.
