2707 6001 d 1 h jermar /trunk/uspace/ Support for mkdir().  
2705 6001 d 17 h jermar /trunk/uspace/ More elegant, flexible and complete version of tmpfs_lookup.  
2699 6009 d 16 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.		  
2694 6014 d 19 h jermar /trunk/uspace/lib/libc/ Add opendir(), rewinddir(), closedir() and some prototypes and stubs. Add dirent.h.  
2693 6015 d 2 h jermar /trunk/uspace/ Add ftruncate() and support for VFS_TRUNCATE to VFS and TMPFS.  
2688 6019 d 19 h jermar /trunk/uspace/ Make uspace rwlock API naming conventions consistent with kernel rwlock API.  
2684 6021 d 20 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).		  
2682 6022 d 2 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 6022 d 2 h jermar /trunk/uspace/ Turn the namespace futex into rwlock.  
2680 6022 d 3 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.		  
2678 6027 d 22 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.		  
2677 6027 d 23 h jermar /trunk/ Rename IPC_M_AS_AREA_SEND to IPC_M_SHARE_OUT. Rename IPC_M_AS_AREA_RECV to
IPC_M_SHARE_IN. Provide user-friendly wrappers for these methods so that even
dummies can get it right. Some applications using simpler protocols still use
these methods directly.		  
2676 6028 d 5 h jermar /trunk/ Simplify the IPC_M_DATA_WRITE protocol. Do not pass the source address space
virtual address to the recipient. This feature was not used anyway. Now
IPC_M_DATA_WRITE and IPC_M_DATA_READ are feature-aligned.		  
2674 6028 d 18 h jermar /trunk/uspace/ Add libc VFS wrapper for VFS_WRITE. Fix a small bug in read(). Place open(),
read() and write() declarations in their respective headers according to SUSv3.		  
2671 6028 d 19 h jermar /trunk/uspace/lib/libc/ Add VFS wrappers for VFS_MOUNT, VFS_OPEN and VFS_READ to libc.  
2670 6032 d 17 h jermar /trunk/uspace/ Move the open(), read() and write() provided by streams.c away so that
these functions won't clash with the real open(), read() and write(), which are
soon to be provided by a libvfs library. Applications can now use open_stdin(),
open_stdout(), read_stdin() and write_stdout(). Later, there might be an option
of providing a custom console file system, which will work similarly to how
streams' open(), read() and write() worked.		  
2668 6032 d 18 h jermar /trunk/uspace/lib/libc/include/io/ Remove file.h.  
2662 6035 d 18 h jermar /trunk/ Add support for IPC_M_DATA_READ calls.  
2660 6035 d 20 h jermar /trunk/ Rename IPC_M_DATA_SEND to IPC_M_DATA_WRITE. Now, when we also add
IPC_M_DATA_READ, it will not clash and cause confusion with userspace wrappers
such as ipc_data_receive(). Rename the forementioned wrappers to
ipc_data_write_send(), ipc_data_write_receive() and ipc_data_write_deliver().		  
2640 6046 d 16 h cejka /trunk/uspace/lib/libc/ Function strncmp() added to libc.  
2637 6054 d 20 h cejka /trunk/ Extended IPC_M_CONNECT_TO_ME to use 3 user defined parameters.
Phone identifier is passed in ARG5.		  
2635 6056 d 20 h cejka /trunk/ Function ipc_connect_me_to sends 3 user defined arguments now.
One argument added also to ipc_forward_fast.
Fixed devmap and improved its test.		  
2622 6065 d 1 h jermar /trunk/ Add mode argument to IPC forward.
This argument can be used to modify the way forward behaves.		  
2621 6067 d 0 h jermar /trunk/uspace/ Modify the async framework to make use of all six syscall arguments.
Supply user-friendly macros as in previous cases.		  
2619 6068 d 18 h jermar /trunk/ Modify ipc_answer_*() to make use of all six syscall arguments. The recommended
means of answering calls is via the ipc_answer_m() macros (where m denotes the
number of return arguments) that automatically decide between the fast register
version or the slow universal version of ipc_answer().		  
2618 6069 d 6 h jermar /trunk/ Modify asynchronous IPC to make use of all six syscall arguments. The preferred
means of asynchronous communication is now via the set of ipc_call_async_m()
macros, where m is the number of payload arguments passed to the kernel. These
macros will automatically decide between the fast and the universal slow version
of ipc_call_async.		  
2616 6069 d 23 h jermar /trunk/uspace/lib/libc/ usleep() should return int. Non-void functions really should return a value, so
fix sleep() to always return 0.		  
2615 6070 d 3 h jermar /trunk/ Modify synchronous IPC to make use of all six syscall arguments. The preferred
means of synchronous communication is now via the set of ipc_call_sync_m_n()
macros, where m is the number of payload arguments passed to the kernel and n is
the number of return values. These macros will automatically decide between the
fast and the universal slow version of ipc_call_sync.		  
2605 6072 d 23 h jermar /trunk/ Start support for six syscall arguments.
This breaks all architectures.		  
2595 6082 d 22 h jermar /trunk/uspace/lib/libc/include/libadt/ Formatting of uspace hash_table.h.  
2592 6084 d 23 h jermar /trunk/uspace/lib/libc/include/ assert.h should include stdio.h  
2588 6086 d 1 h jermar /trunk/uspace/ Add ipc_answer_fast_[01] macros so that ipc_answer_fast() users don't have to
write zero arguments all the time.		  
2586 6089 d 17 h jermar /trunk/uspace/lib/libc/ Unify implementations of TLS variant I and variant II __alloc_tls() and
__free_tls_arch().		  
2581 6091 d 19 h jermar /trunk/uspace/lib/libc/ For architectures that make use of TLS variant II (i.e. amd64, ia32 and
sparc64), fix the way TLS and TCB is allocated. Now, TLS is allocated using
memalign() with the alignment specified in _tls_alignment. Size of TLS data
itself is rounded up to be a multiple of _tls_alignment.		  
2568 6117 d 9 h jermar /trunk/uspace/ Rename fibril_schedule_next_adv() to fibril_switch(). Rename
fibril_schedule_next() to fibril_yield(). Some fibril structures could be
uninitialized, set them to zero in fibril_setup(). For some fibrils, the stack
member can be NULL (e.g. every thread's first/main fibril); don't do free on
these stacks when cleaning up after a dead fibril.		  
2564 6117 d 9 h jermar /trunk/uspace/lib/libc/ Support for time() function.  
2550 6121 d 23 h cejka /trunk/ Fixed naming convention in IPC.  
2547 6122 d 2 h cejka /trunk/ Added basic support for device mapper.  
2541 6123 d 3 h jermar /trunk/uspace/ Header cleanup.
Move off_t, size_t and ssize_t into sys/types.h.
Get rid off the non-standard and dummy types.h.		  
2531 6131 d 20 h jermar /trunk/uspace/ VFS work.
Implement VFS_REGISTER part of the protocol in the FAT file system.

IPC work.
Rename ipc_data_send_accept() to ipc_data_receive() and ipc_data_send_answer()
to ipc_data_deliver(). Introduce ipc_data_send().
