2021-07-16cpukit: occured -> occurredSebastian Huber1-10/+10
2021-03-26dosfs: Use peek supportChristian Mauderer1-5/+16
This speeds up reading fragmented files. Fix #3689
2020-04-28doxygen: Switch @brief and @ingroupSebastian Huber1-1/+2
This order change fixes the Latex documentation build via Doxygen.
2020-04-16Canonicalize config.h includeSebastian Huber1-1/+1
Use the following variant which was already used by most source files: #ifdef HAVE_CONFIG_H #include "config.h" #endif
2017-09-06dosfs: Fix fat_file_update()Sebastian Huber1-5/+3
Do not update the non-existant meta-data of the root directory. Update #2944.
2017-03-16dosfs: Simplify fat_file_open()Sebastian Huber1-3/+1
Update #2929.
2017-03-16dosfs: Fix fat_file_write()Sebastian Huber1-18/+5
Remove forced overwrite which leads to file data corruption. The logic to determine a forced overwrite was fundamentally broken. For simplity, disable this feature. Update #2622.
2014-10-23dosfs: Write meta-data only if it changedSebastian Huber1-12/+10
2014-10-23dosfs: Support ctime and mtimeSebastian Huber1-0/+34
Implement ctime and mtime updates according to POSIX. The ctime is mapped to the FAT create time and date. The mtime is mapped to the FAT last modified time and date. For the atime use the mtime for simplicity.
2013-08-21dosfs: Use unprotected chain operationsSebastian Huber1-2/+2
This area is protected by the FAT file system instance lock.
2013-02-20dosfs: Fix file length updateSebastian Huber1-2/+3
2013-02-15dosfs: Fix file extendSebastian Huber1-23/+24
Only append a valid cluster chain (cluster added > 0), otherwise we overwrite the root directory cluster (cluster 0) of a FAT12 or FAT16 with arbitrary data.
2013-01-30dosfs: Always release the buffersSebastian Huber1-22/+23
Release the buffers also if this is not the last reference to the file object since otherwise we may hold modified data indefinitely.
2012-12-20libfs: Doxygen Enhancement Task #6"Mathew Kallada1-4/+7
2012-12-05dosfs: Cluster write optimizationRalf Kirchner1-75/+156
Separate cluster write from sector write for quick file write. New test fstests/fsdosfswrite01.
2012-07-11dosfs: Use fs_info instead of mt_entrySebastian Huber1-73/+64
2012-06-04dosfs: Fix for no space left on device conditionSebastian Huber1-3/+5
The file size was wrong in the no space left on device condition. This resulted in turn in a read of an invalid block which lead to an EIO error status.
2012-05-11Remove All CVS Id Strings Possible Using a ScriptJoel Sherrill1-2/+0
Script does what is expected and tries to do it as smartly as possible. + remove occurrences of two blank comment lines next to each other after Id string line removed. + remove entire comment blocks which only exited to contain CVS Ids + If the processing left a blank line at the top of a file, it was removed.
2012-05-11dosfs: Remove fat_file_datasync()Sebastian Huber1-59/+0
The fat_file_datasync() read every cluster of the file into the cache and then synchronized it step-by-step. For unmodified buffers this is a non-operation. For modified buffers this will wake-up the swapout task which performs then a single buffer write operation. This is usually quite inefficient. Firstly we do single buffer writes, secondly we may perform a lot of unnecessary read operations (for huge files this is really bad), and thirdly this leads likely to cache evictions. The synchronization procedure is replaced by a simple rtems_bdbuf_sync_dev(). This has the side-effect that also buffers not related to the file are synchronized, but since the modified list is normally short this should be acceptable.
2012-05-11Filesystem: PR1893: Fix write and truncate handlerSebastian Huber1-7/+29
Space that grows due to truncate or write offsets beyond the current file size must be zero filled.
2012-03-13libblock: Change bdbuf APISebastian Huber1-1/+1
The functions o rtems_bdbuf_get(), o rtems_bdbuf_read(), o rtems_bdbuf_syncdev(), and o rtems_bdbuf_purge_dev(), use now the disk device instead of the device identifier. This makes bdbuf independent of rtems_disk_obtain() and rtems_disk_release(). It is the responsiblity of the file system to obtain the disk device. This also reduces the overhead to get a buffer. The key for the AVL tree uses now the disk device instead of the device identifier. The pointer is interpreted as an unsigned integer. This reduces the memory overhead and makes the comparison operation a bit faster. Removed function rtems_bdbuf_purge_major(). This function was too destructive and could have unpredictable side effects.
