Add ISR lock to chain control for proper SMP protection. Replace
rtems_chain_extract() with rtems_chain_explicit_extract() and
rtems_chain_insert() with rtems_chain_explicit_insert() on SMP
configurations. Use rtems_chain_explicit_extract() and
rtems_chain_explicit_insert() to provide SMP support.
Move implementation specific parts of rbtree.h and rbtree.inl into new
header file rbtreeimpl.h. The rbtree.h contains now only the
application visible API.
utf8proc is a library for processing UTF-8 encoded Unicode strings.
Some features are Unicode normalization, stripping of default ignorable characters, case folding and detection of grapheme cluster boundaries.
For now utf8proc is intended for normalizing and folding strings for comparison purposes within the UTF-8 support of the FAT file system.
This test will call interface methods of library utf8proc in order to make sure they compiled and linked ok.
The library is third party, thus it should be sufficient for us to make sure we can build it correctly.
This commit deletes all RTEMS ChangeLog files. These files have been abandoned
since converting to git version control. The historical data may be recovered
by checking out any commit before this one. Most of the contents of these
ChangeLog files can also be found in the git log.
Two external ChangeLog files, ChangeLog.slac and ChangeLog.zlib, remain.
It is invalid to issue a SIZE command once a data transfer is
in progress. For reads we issue the SIZE command before the RETR
command and get a snapshot of the file size. For writes the file size
is initialized to zero and incremented for each write chunk.
This reduces the start-up time of the network stack.
With a 1ms tick the ticks since boot value overflows after approximately
50 days. This problem is avoided with the
rtems_clock_get_uptime_seconds() function.
Add and use rtems_blkdev_request_done(). Block device transfer requests
must signal the completion status now with rtems_blkdev_request_done().
The return value of the block device IO control will be ignored for
transfer requests.
The first parameter of rtems_blkdev_request_cb is now the transfer
request structure.
Renamed rtems_blkdev_request::req_done to rtems_blkdev_request::done to
break third party drivers at compile time, otherwise this API change
would result in runtime errors.
The set block size must synchronize and purge the disk to avoid an
inconsistent cache state and data corruption. The synchronization is
optional depending on the new sync parameter. In some contexts a
synchronization must not be performed, e.g. during disk creation.
The work areas (RTEMS work space and C program heap) will be initialized
now in a separate step and are no longer part of
rtems_initialize_data_structures(). Initialization is performed with
tables of Heap_Area entries. This allows usage of scattered memory
areas present on various small scale micro-controllers.
The sbrk() support API changes also. The bsp_sbrk_init() must now deal
with a minimum size for the first memory chunk to take the configured
work space size into account.
The _Heap_Extend() has now the same signature as _Heap_Initialize().
The 4th parameter is ignored (page size in _Heap_Initialize()).
Add Heap_Area and Heap_Initialization_or_extend_handler.
Add and test _Heap_No_extend().
This helps to do a table based heap initialization and extension.
Create a table of Heap_Area elements and iterate through it. Set the
handler to _Heap_Initialize() in the first iteration and then to
_Heap_Extend().
Formerly, mghttpd was conditional only on networking being
enabled. It uses on pthread and must also be conditional
on POSIX threads support being enabled.
