2717 6039 d 23 h cejka /trunk/uspace/app/ash/tools/ Ash: removed .map file commited by mistake.  
2716 6039 d 23 h cejka /trunk/uspace/app/ash/tools/ Ash: fixed recursive Makefile.  
2715 6040 d 0 h cejka /trunk/uspace/app/ash/ Ash - add recursion to Makefile to create build tools in subdirectory.  
2714 6040 d 1 h cejka /trunk/uspace/app/ash/ Initial commit of ash shell.
It cannot be compiled yet.
 
2713 6041 d 0 h decky /trunk/kernel/arch/amd64/src/boot/ remove fake tab  
2712 6041 d 0 h decky /trunk/kernel/ prettyprint output  
2711 6045 d 19 h jermar /trunk/uspace/ Remove the debugging hack from tmpfs_init(), which created several files and
directories on the filesystem. TMPFS is now self-sufficient enough to be able
to create its content via the standard VFS interface.
 
2710 6045 d 20 h jermar /trunk/uspace/ VFS_WRITE and tmpfs_write fixes.  
2709 6045 d 22 h jermar /trunk/uspace/srv/vfs/ VFS_OPEN and VFS_WRITE now understand O_APPEND.  
2708 6045 d 22 h jermar /trunk/uspace/ VFS_OPEN now understands O_CREAT and O_EXCL.  
2707 6046 d 0 h jermar /trunk/uspace/ Support for mkdir().  
2706 6046 d 4 h jermar /trunk/uspace/srv/fs/tmpfs/ Move handling of the miss on excessive components out of the main loop in
tmpfs_lookup.
 
2705 6046 d 16 h jermar /trunk/uspace/ More elegant, flexible and complete version of tmpfs_lookup.  
2704 6047 d 2 h jermar /trunk/uspace/srv/vfs/ Additional VFS lookup flags.  
2703 6047 d 22 h jermar /trunk/kernel/arch/amd64/ Grow the initial identity mapping from 64M to 4G.
We should not allocate GDT's from above 4G or the amd64 will occassionally
triple-fault again.
 
2702 6048 d 1 h decky /trunk/kernel/arch/ia32/src/mm/ change cstyle to human-readable form  
2701 6048 d 3 h jermar /trunk/kernel/ Fix cstyle and (c) to 2008.  
2700 6054 d 1 h jermar /trunk/uspace/ Introduce the notion of lflag (i.e. lookup flags) to support the ability to
limit the scope of VFS node types that can be opened by open() and opendir(). In
the future, lflag will also specify actions for VFS_LOOKUP handlers that will be
carried out in situations such as the VFS node is not found (e.g. implementation
of mkdir() and open() with O_CREAT in oflag).
 
2699 6054 d 15 h jermar /trunk/uspace/ Finish implementation of readdir(). Functions from this family are implemented
via using file descriptors for directories. For example, readdir() is
implemented as read() from an open directory. Of course, FS implementations
must understand that they are asked to read a directory and behave accordingly.
 
2698 6054 d 21 h jermar /trunk/uspace/srv/vfs/ Small fix for VFS_TRUNCATE. Move lookup and registration code to separate
modules.
 
2697 6058 d 1 h decky /trunk/kernel/ amd64: shorten kernel address space by 2 GB to support proper mapping of more than 2 GB of physical memory  
2696 6058 d 5 h decky /trunk/kernel/arch/mips32/ initial support for dorder device in MSIM  
2695 6058 d 5 h decky /trunk/contrib/conf/ make msim.conf compatible with MSIM 1.3.x  
2694 6059 d 18 h jermar /trunk/uspace/lib/libc/ Add opendir(), rewinddir(), closedir() and some prototypes and stubs. Add dirent.h.  
2693 6060 d 1 h jermar /trunk/uspace/ Add ftruncate() and support for VFS_TRUNCATE to VFS and TMPFS.  
2692 6061 d 21 h decky /trunk/kernel/arch/amd64/ move cpuid tests from amd64.c to boot.S  
2691 6063 d 19 h jermar /trunk/uspace/srv/vfs/ Improve the API for converting (VFS triplets, size) to VFS nodes by introducing
a new type for results of vfs_lookup_internal().
 
2690 6064 d 17 h jermar /trunk/uspace/srv/ Make a distinction between VFS operations that are common to VFS and FS
implementations, operations that are VFS only and operations that are FS
implementations only.
 
2689 6064 d 18 h jermar /trunk/uspace/srv/vfs/ Merge all VFS operations into one file.  
2688 6064 d 18 h jermar /trunk/uspace/ Make uspace rwlock API naming conventions consistent with kernel rwlock API.  
2687 6064 d 18 h jermar /trunk/uspace/srv/ Management of the cached VFS node size.  
2686 6064 d 19 h jermar /trunk/uspace/srv/fs/tmpfs/ Previous commit was toxic. When emulating gaps, zero out the reallocated buffer, not the original one.  
2685 6064 d 19 h jermar /trunk/uspace/srv/fs/tmpfs/ TMPFS must handle file gaps.  
2684 6066 d 19 h jermar /trunk/ Add libc and VFS implementation of lseek(), VFS_SEEK resp.
Add the size member to the VFS node structure (not yet initialized).
 
2683 6066 d 22 h jermar /trunk/uspace/srv/vfs/ Introduce the open file lock. Modify vfs_rdwr() to take this lock into account
when reading or writing from/to an open file.
 
2682 6067 d 1 h jermar /trunk/uspace/ Fix type in declaration of VFS node rwlock.
Introduce a dedicated type for futexes. Make the existing futex code use this
newly introduced type and fix formatting in futex.c.
 
2681 6067 d 1 h jermar /trunk/uspace/ Turn the namespace futex into rwlock.  
2680 6067 d 2 h jermar /trunk/uspace/ Add basic rwlock API for uspace so that VFS can be designed/implemented using
this API. So far, the implementation of this API merely wraps futexes into
rwlocks. Real rwlocks are wanted by ticket #54.

Using the new rwlock API, replace the VFS node content futex with an rwlock.
Lock the contents rwlock as reader on reads and as writer on writes.
 
2679 6070 d 18 h jermar /trunk/uspace/srv/vfs/ Rename unlink_futex to namespace_futex and introduce a new futex for serializing
concurrent access to a VFS node's contents by multiple clients.
 
2678 6072 d 21 h jermar /trunk/uspace/ The IPC_M_SHARE_* and IPC_M_DATA_* calls pass through 3 stages. Rename the send,
receive and deliver wrappers to names ending with 'start', 'receive' and
'finalize', respectively. This should make it clearer for dummies.
