So only call getpid once, thus not allowing st_dev values to mysteriously change. Wed Oct 5 12:56:53 1994 Michael I Bushnell * alloc.c (diskfs_alloc_node): Abort if free inode has translator attached. Tue Oct 4 18:33:35 1994 Michael I Bushnell * pager.c (pager_unlock_page): Call diskfs_catch_exception.

(pager_unlock_page): Use rwlock_writer_lock to lock NP->dn->dinlock, NP->dn->sinlock, and NP->dn->datalock. * sizes.c (diskfs_truncate, diskfs_grow): Change locks of DATALOCK field to use rwlock_writer_{un,}lock. (sindir_drop): Ditto for SINLOCK field. (dindir_drop): Ditto for DINLOCK field. Mon Jun 6 19:23:26 1994 Michael I Bushnell (mib@churchy.gnu.ai.mit.edu) * sizes.c (diskfs_grow): After realloccg, zero new data (which I'm not sure is really necessary, but until I figure it out, this is safest). Also poke old data (the latter only if the block has moved)--otherwise the kernel won't know to page it out to the new location. (poke_pages): When poking, be careful not to actually change the data. LEN should be end - start, not start - end. Fri Jun 3 12:37:27 1994 Michael I Bushnell (mib@churchy.gnu.ai.mit.edu) * inode.c (iget): When we find the node in the table, acquire the mutex *after* incrementing NP->references and unlocking diskfs_node_refcnt_lock; otherwise we can deadlock against diskfs_nput. Thu Jun 2 12:16:09 1994 Michael I Bushnell (mib@churchy.gnu.ai.mit.edu) * ufs.h (sblock_dirty, csum_dirty, alloclock): New global variables. * alloc.c (alloclock): Remove static keyword.. * alloc.c (realloccg): Set sblock_dirty after changing sblock. (blkpref): Likewise. (fragextend): Likewise. (alloccg): Likewise. (alloccgblk): Likewise. (ialloccg): Likewise. (blkfree): Likewise. (diskfs_free_node): Likewise. * hyper.c (diskfs_set_hypermetadata): Likewise. * alloc.c (fragextend): Set csum_dirty after changi csum. (alloccg): Likewise. (alloccgblk): Likewise. (ialloccg): Likewise. (blkfree): Likewise. (diskfs_free_node): Likewise. * hyper.c (diskfs_set_hypermetadata): Acquire alloclock while writing hypermetadata. Only write csum and sblock if csum_dirty or sblock_dirty, respectively, is set, and then clear it after starting the write. * main.c (main): Likewise. * sizes.c (diskfs_truncate): Don't turn off caching; the new light reference system takes care of this. * pager.c (diskfs_get_filemap): No longer necessary to turn on caching here, because truncate no longer turns it off. * inode.c (diskfs_lost_hardrefs, diskfs_new_hardrefs): New functions. * pager.c (drop_pager_softrefs, allow_pager_softrefs): New functions. (sin_map): Use diskfs_nref_light, not diskfs_nref. (diskfs_get_filemap): Use diskfs_nref_light, not diskfs_nref. (pager_clear_user_data): Use diskfs_nrele_light, not diskfs_nrele. * ufs.h (drop_pager_softrefs, allow_pager_softrefs): New declarations. Wed Jun 1 13:35:11 1994 Michael I Bushnell (mib@churchy.gnu.ai.mit.edu) * sizes.c (diskfs_truncate): After calling sin_unmap, turn off caching on the sininfo pager so that it gets freed promptly (there's generally no value in keeping it around because there is no live fileinfo pager). * pager.c (diskfs_get_filemap): Make sure we turn caching back on here, however, if we start using the file pager. * pager.c (sin_map): When np->dn->sininfo is set, we have to insert a valid send right after fetching the receive name. * pager.c (sin_unmap, din_unmap): New functions. (pager_clear_user_data): Call sin_unmap and din_unmap instead of doing it right here. * sizes.c (diskfs_truncate): Call sin_unmap instead of doing it right here. (sindir_drop): Call din_unmap instead of doing it right here. Also, call it always, not just when wo do dindir_drop. * sizes.c (diskfs_grow): After alloc into sindir area, unmap it if we don't have an active data pager. * ufs.h (sin_unmap, din_unmap): New declarations. * sizes.c (diskfs_grow): In computing OSIZE in the realloc case of lbn < NDADDR, deal correctly with the case where np->allocsize is already an integral number of blocks. * sizes.c (diskfs_grow): Compute SIZE correctly. * alloc.c (alloc, realloccg, blkfree): When checking validity of size arguments, also make sure the size isn't zero. * alloc.c (diskfs_alloc_node): Lock ALLOCLOCK before checking sblock->fs_cstotal.cs_nifree. Tue May 31 18:47:42 1994 Roland McGrath (roland@geech.gnu.ai.mit.edu) * ufs.h (DONT_CACHE_MEMORY_OBJECTS): Define it. * dir.c (diskfs_direnter: case TAKE): Assert that OLD->d_reclen >= NEEDED, not that it is strictly >. Tue May 31 11:10:28 1994 Michael I Bushnell (mib@churchy.gnu.ai.mit.edu) * sizes.c (diskfs_grow): Call diskfs_node_update (but don't wait) after successful completion to prevent old data from hanging around too long and getting flushed all at once from the kernel. * sizes.c (diskfs_grow): Change SIZE to be the size of the last block allocated. Delete variable NSIZE; use SIZE instead. Fri May 27 13:15:26 1994 Michael I Bushnell (mib@geech.gnu.ai.mit.edu) * sizes.c (diskfs_truncate): Set NP->dn_stat_dirty after each modification of NP->dn_stat. * sizes.c (diskfs_truncate): Compute new value of NP->allocsize correctly. * inode.c (iget): Set NP->allocsize to be the *actual* allocsize. Thu May 26 11:51:45 1994 Michael I Bushnell (mib@churchy.gnu.ai.mit.edu) * sizes.c (diskfs_truncate): In blkfree loop of blocks past NDADDR, subtract NDADDR from idx to index correctly into sinloc array. Start this loop with idx not less than NDADDR. (diskfs_truncate): If olastblock == NDADDR, then we also need to truncate blocks (one) mapped by single indirect blocks. (diskfs_truncate): New variable `first2free'. Use in place of older losing calculations involving lastblock. (sindir_drop): Rename parameters to be FIRST and LAST. Change interpretation of FIRST by one to correspond with changed call in diskfs_truncate. * pager.c (sin_remap): When computing NEWSIZE, round up to a page boundary, thus mimicing the SINDIR computation in pager_report_extent properly. * pager.c (pager_unlock_page) [case SINDIR; vblkno == 0]: Read from ....di_ib[INDIR_SINGLE] rather than invalid data before NP->dn->dinloc. * alloc.c (alloc) [nospace]: Unlock alloclock. (realloccg): Unlock alloclock before jumping to nospace. (blkpref) [!(lbn < NDADDR)]: Unlock alloclock before returning success. * sizes.c (diskfs_grow): When allocing a block past NDADDR, the tbl arg to blkpref is the table of direct block pointers NP->dn->sinloc, not the table of indirect block pointers ...->di_ib. * sizes.c (diskfs_grow): When writing into the SINDIR area, call sin_map instead of sin_remap if the sindir isn't already mapped. Also set np->allocsize *before* calling sin_map, but *after* calling sin_remap, to meet the requirements of those separate routines. * sizes.c (diskfs_grow): If END isn't bigger than NP->allocsize, then don't try and do anything. In computation of LBN and the first use of NB, round up to block boundary correctly. Don't attempt to realloc an old block if the size is 0 (in which case NB is -1 and unsigned comparison rules might foul things up). Mon May 23 13:18:33 1994 Michael I Bushnell (mib@churchy.gnu.ai.mit.edu) * Makefile (ufs): Give -n in the proper order to rsh. * main.c: Include . * ufs.h (DONT_CACHE_MEMORY_OBJECTS): New compilation flag. * pager.c (pager_report_attributes): Deleted function. (MAY_CACHE): New macro; more useful form for using DONT_CACHE_MEMORY_OBJECTS. (sin_map, pager_init, diskfs_get_filemap): Provide new args in calls to pager_create. * sizes.c (MAY_CACHE): New macro; more useful form for using DONT_CACHE_MEMORY_OBJECTS. (diskfs_truncate): Use MAY_CACHE in calls to pager_change_attributes. Fri May 20 18:52:41 1994 Michael I Bushnell (mib@geech.gnu.ai.mit.edu) * sizes.c (diskfs_truncate): Force any delayed copies of the vanishing region to be taken immediately before stopping, and prevent any new delayed copies from being made until we are done manipulating things. (poke_pages): New function. * pager.c (pager_report_attributes): New function. Wed May 18 15:51:40 1994 Michael I Bushnell (mib@churchy.gnu.ai.mit.edu) * alloc.c (alloc, realloccg, diskfs_alloc_node, alloccgblk, blkfree, diskfs_free_node, mapsearch): Added helpful strings to asserts. (realloccg): Split up assert. Tue May 17 13:26:22 1994 Michael I Bushnell (mib@churchy.gnu.ai.mit.edu) * main.c (main): Delete unused variable PROC. Mon May 16 15:32:07 1994 Michael I Bushnell (mib@churchy.gnu.ai.mit.edu) * alloc.c (realloccg): When fragextend succeeds, bother to set *PBN. * sizes.c (diskfs_grow): In fragment growth case, NSIZE should not be the amount to hold SIZE (SIZE is the amount the file is growing by), but rather the old size of the fragment plus the SIZE. * dir.c (diskfs_direnter case COMPRESS): Rewrite loop to deal properly with the case where from and to overlap. Mon May 9 16:51:44 1994 Michael I Bushnell (mib@geech.gnu.ai.mit.edu) * main.c (ufs_version): New variable. (save_argv): New variable. (main): Set save_argv. (diskfs_init_completed): New function. Thu May 5 19:06:54 1994 Michael I Bushnell (mib@geech.gnu.ai.mit.edu) * Makefile (exec_server_image.o): Use -n when calling rsh. Thu May 5 07:39:38 1994 Roland McGrath (roland@churchy.gnu.ai.mit.edu) * Makefile ($(OBJS)): Use $(includedir) instead of $(headers) in deps.
