(diskfs_reload_global_state): New function. Fri Oct 13 15:03:37 1995 Miles Bader * main.c (main): Use new handy diskfs routines and get rid of tons of junk. Main should be almost all ufs-specific now. (USAGE, usage, SHORT_OPTS, long_opts, parse_opt, trans_parse_arg): RIP. (printf_lock): Initialize. Thu Oct 12 18:48:04 1995 Miles Bader * pager.c (pager_unlock_page, pager_write_page, pager_read_page): Use diskfs_device_{read,write}_sync instead of dev_{read,write}_sync. * hyper.c (diskfs_set_hypermetadata): Ditto. * sizes.c (diskfs_grow): Ditto. * pager.c (pager_report_extent): Calculate the pager size. * ufs.h (dev_read_sync, dev_write_sync, dev_write, diskpagersize): Decls removed. * Makefile (SRCS): Remove devio.c. * ufs.h (ufs_device, ufs_device_name): Variables removed. * inode.c (diskfs_S_file_get_storage_info): Use DISKFS_DEVICE instead of UFS_DEVICE, and DISKFS_DEVICE_NAME instead of UFS_DEVICE_NAME. Sat Oct 7 20:47:56 1995 Miles Bader * main.c (diskfs_init_completed): Function deleted (now in libdiskfs). (thread_cancel): Function deleted. Fri Oct 6 17:30:23 1995 Miles Bader * inode.c (diskfs_S_file_get_storage_info): Change type of ADDRESSES to off_t **, and add the BLOCK_SIZE parameter.

Mon Aug 28 17:07:36 1995 Roland McGrath * Makefile (ufs): Depend on ../libshouldbeinlibc/libshouldbeinlibc.a. Fri Aug 25 17:14:09 1995 Michael I. Bushnell, p/BSG * sizes.c (diskfs_truncate): When freeing direct blocks mentioned in a single indirect block, or single indirect blocks mentioned in a double, only call the free routine (ffs_blkfree or indir_release, respectively) if the block is actually allocated.

Mon Jul 17 14:35:25 1995 Michael I Bushnell * pager.c (thread_function): Don't have any global timeout here; we don't use it anyhow. Thu Jul 6 15:42:52 1995 Michael I Bushnell * Makefile: Removed dependencies that are now automatically generated. Mon Jun 26 20:17:42 1995 Michael I Bushnell * pager.c: Include . (diskfs_pager_users): New function.

(parse_opt): New function. * Makefile (CPPFLAGS): Add -I../lib, to get include lib include files, and $(CPPFLAGS-$(notdir $<)) to get file-specific cpp options. Add a vpath for %.c to ../lib, so we can use source files from there. Mon May 15 13:14:48 1995 Michael I Bushnell * pager.c (pager_clear_user_data): Doc fix. Sat May 13 05:04:11 1995 Roland McGrath * Makefile (OBJS): Remove exec_server_image.o. (exec_server_image.o): Rule removed. Mon May 8 08:43:43 1995 Miles Bader * dir.c (diskfs_lookup): When looping back to try_again: because we're looking up "..", be sure and trash the mapping we made of the directory's pager -- otherwise the reference to the pager never gets dropped and we can never free the node. * dir.c (diskfs_lookup): ds->type was being compared to LOOKING, which value it can never have. Compare ds->stat against LOOKING instead. * pager.c (pager_clear_user_data): Don't die when called on the disk pager. * inode.c (write_all_disknodes): Fix typo `alloc' --> `alloca'. Tue May 2 11:59:09 1995 Michael I Bushnell * pager.c (pager_clear_user_data): Acquire pagerlistlock around modifications to UPI->next/prevp list structure. Fri Apr 28 19:02:05 1995 Michael I Bushnell * inode.c (write_all_disknodes): We have to really lock the nodes around the calls to diskfs_set_node_times and write_node; this in turn forces us to have real refereces. Thu Apr 13 16:36:57 1995 Miles Bader * main.c (main): Don't abort if a std file descriptor is already open. Tue Apr 4 20:08:25 1995 Michael I Bushnell * inode.c (diskfs_set_translator): When freeing passive translator, account for blocks freed in NP->dn_stat.st_blocks. Fri Mar 31 13:43:27 1995 Michael I Bushnell * sizes.c (diskfs_truncate): Don't acquire writer lock on NP->dn->allocptrlock until after forcing delayed copies through; otherwise the pageins will deadlock attempting to get a reader lock to service them. This is safe, because we only need NP->allocsize here, and that can't change as long as we hold NP->lock. Mon Mar 20 13:58:44 1995 Michael I Bushnell * consts.c (diskfs_synchronous): New variable.

Fri Nov 11 11:45:38 1994 Michael I Bushnell * hyper.c (diskfs_set_hypermetadata): Always use dev_write_sync to avoid device_write bug that says you can't modify the buffer until device_write returns. Also remember to deallocate BUF. Thu Nov 10 13:27:09 1994 Michael I Bushnell * main.c (main): Issue decent prompt. * hyper.c (diskfs_set_hypermetadata): Copy CSUM into a page-aligned page-sized buffer for disk write to avoid inane kernel bug.

Thu Oct 27 20:58:08 1994 Michael I Bushnell * dir.c (diskfs_lookup): diskfs_get_filemap returns a send right, so don't create an additional one here.

(saved_argv): Variable removed. (main): Don't set saved_argv. Pass ARGV to diskfs_start_bootstrap. Wed Oct 5 22:18:46 1994 Michael I Bushnell * inode.c (read_disknode): If we are the bootstrap filesystem, then getpid changes once proc starts up. 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.

Fri Sep 30 11:25:36 1994 Michael I Bushnell * dir.h: Delete DT_* definitions; they are now in . * dir.c (diskfs_get_directs): Set USERP->d_type as DT_UNKNOWN. When the bugs in the type fields are fixed (dealing with multiple links and mode changes) then this can actually return the value. Thu Sep 29 17:16:58 1994 Roland McGrath * main.c (main): Test getpid()>0 to decide we are a normal translator instead of the boot fs. Fetch bootstrap port after possibly calling diskfs_parse_bootargs, not before.

Mon Sep 26 12:50:38 1994 Michael I Bushnell * inode.c (diskfs_lost_hardrefs): "Know" that a pager starts with a portinfo; we don't actually have access to the pager struct here.

(struct disknode): New member `dirty'. * inode.c (iget): Initialize DN->dirty. * bmap.c (mark_indir_dirty): New function. * pager.c (pager_unlock_page): Call mark_indir_dirty before writing into indirect blocks.

Sat Sep 10 11:41:06 1994 Roland McGrath * main.c (main): When started up as a passive translator, open fds 0, 1, and 2 on /dev/console for debugging messages.

Fri Sep 9 13:02:33 1994 Michael I Bushnell * main.c (trans_parse_args): Fix and enable. Tue Sep 6 11:29:55 1994 Michael I Bushnell * inode.c (iget): Remove old assert test that checked for bad inode block allocations. Thu Sep 1 11:39:12 1994 Michael I Bushnell * tables.c: Don't include "ufs.h"; include . Then this file can be used unmodified by fsck. Tue Aug 30 13:36:37 1994 Michael I Bushnell * inode.c (diskfs_set_translator): ffs_blkfree doesn't have a return value. Mon Aug 29 12:49:17 1994 Michael I Bushnell * inode.c (diskfs_set_translator): If NAMELEN is zero, then make the node have no translator. Fri Aug 26 12:28:20 1994 Michael I Bushnell * inode.c (read_disknode): 4.4 fsck sometimes sets the author field to -1 to mean "ignore old uid location"; take that to mean "author == uid".

(struct dirstat): New structure to cache mapping between lookup and commit operation and avoid use of diskfs_node_rdwr. (diskfs_lookup): Map directory ourselves.

(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 >.

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.

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.
