dholland | Add new accessors for the d_type and d_namlen fields of struct lfs_direct. Napalm the old byteswap access logic for these.

1.14 |
| 01-Sep-2015 |
dholland | Add byteswapping to the dinode accessors.
This prevents regressions in the ulfs code when switching to the new accessors. Note that while adding byteswapping to the other accessors is straightforward, I haven't done it yet; and that also is not enough to make LFS_EI work, because there are places lying around that bypass the accessors for one reason and another and all of them need to be updated. That is going to have to wait for a later day as LFS_EI is not on the critical path right now.

1.13 |
| 12-Aug-2015 |
dholland | Make 32-bit and 64-bit versions of CLEANERINFO.
XXX: while this is written to disk, it seems like much of it would XXX: be better set up as a commpage shared with the cleaner.

1.12 |
| 12-Aug-2015 |
dholland | Fix assorted 64->32 truncations related to BLOCK_INFO.
Also make note of a cleaner limitation: it seems that when it goes to coalesce discontiguous files, it mallocs an array with one BLOCK_INFO for every block in the file. Therefore, with 64-bit LFS, on a 32-bit platform it will be possible to have files large enough to overflow the cleaner's address space. Currently these will be skipped and cause warnings via syslog.
At some point someone should rewrite the logic to coalesce files to use chunks of some reasonable size, as discontinuity between such chunks is immaterial and mallocing this much space is silly and fragile. Also, the kernel only accepts up to 65536 blocks at a time for bmapv and markv, so processing more than this at once probably isn't useful and may not even work currently. I don't want to change this around just now as it's not entirely trivial.

1.11 |
| 02-Aug-2015 |
dholland | Add a (draft) 64-bit superblock. Make things build again.
Add pieces of support for using both superblock types where convenient, and specifically to the superblock accessors, but don't actually enable it anywhere.
First substantive step on PR 50000.

1.10 |
| 02-Aug-2015 |
dholland | Second batch of 64 -> 32 truncations in lfs, along with more minor tidyups and corrections in passing.
|
1.9 |
| 28-Jul-2015 |
dholland | Use lfs_accessors.h in conjunction with the cleaner's struct clfs. Remove previous hacks.
|
1.8 |
| 28-Jul-2015 |
dholland | Add a new lfs header file: lfs_accessors.h.
This contains all the accessor functions and macros out of lfs.h. Add an include of lfs_accessors.h after all uses of lfs.h... except for code that wants to define its own struct lfs-alike that the accessors are supposed to play along with. For these, set STRUCT_LFS and include lfs_accessors.h after the necessary structure has been defined, so that lfs_accessors.h can emit functions in terms of it.
|
1.7 |
| 24-Jul-2015 |
dholland | More lfs superblock accessors. (This changes the rest of the code over; all the accessors were already added.)
The difference between this commit and the previous one is arbitrary, but the previous one passed the regression tests on its own so I'm keeping it separate to help with any bisections that might be needed in the future.

1.6 |
| 24-Jul-2015 |
dholland | Switch to accessor functions for elements of the LFS on-disk superblock. This will allow switching between 32/64 bit forms on the fly; it will also allow handling LFS_EI reasonably tidily. (That currently doesn't work on the superblock.)
It also gets rid of cpp abuse in the form of fake structure member macros.
Also, instead of doing sleep/wakeup on &lfs_avail and &lfs_nextseg inside the on-disk superblock, add extra elements to the in-memory struct lfs for this. (XXX: these should be changed to condvars, but not right now)
XXX: this migrates a structure needed by the lfs code in libsa (struct salfs) into lfs.h, where it doesn't belong, but for the time being this is necessary in order to allow the accessors (and the various lfs macros and other goop that relies on them) to compile.

lukem | fix WARNS=3 issues; * sprinkle const * avoid tests < 0 on unsigned types * test fwrite() returns nmemb not <0
|
1.4 |
| 31-Jul-2006 |
martin | branches: 1.4.28; Make filehandles opaque to userland
|
1.3 |
| 13-Jul-2006 |
martin | Fix alignement problems for fhandle_t, exposed by gcc4.1.
While touching all vptofh/fhtovp functions, get rid of VFS_MAXFIDSIZ, version the getfh(2) syscall and explicitly pass the size available in the filehandle from userland.
Discussed on tech-kern, with lots of help from yamt (thanks!).

perseant | Be more careful about checking return value of {m,re}alloc().
In determining when to stop reading segments when counting bytes (-b flag), total the sizes of the blocks we're actually writing instead of assuming they are all full blocks: many could be fragments or inode blocks. This increases the number of segments per Ifile write, markedly improving the efficiency of the cleaner in the small file case.

perseant | A new version of the cleaner. In general, works about as well as the old cleaner, but with more legible code.
Includes code for reading and writing to the raw disk device (so that an unmounted fs could be cleaned), for the use of a single daemon to clean multiple filesystems to save on resources, and for recording the old contents of cleaned segments to offline storage for regression testing of the LFS system as a whole; though these new features are not properly tested at this point.
