| 2002-02-08 | - Rename FILE_{,UN}USE to FREF and FRELE. USE is a bad verb and we don't have | Artur Grabowski | |
| the same semantics as NetBSD anyway, so it's good to avoid name collissions. - Always fdremove before freeing the file, not the other way around. - falloc FREFs the file. - have FILE_SET_MATURE FRELE the file (It feels like a good ortogonality to falloc FREFing the file). - Use closef as much as possible instead of ffree in error paths of falloc:ing functions. closef is much more careful with the fd and can deal with the fd being forcibly closed by dup2. Also try to avoid manually calling *fo_close when closef can do that for us (this makes some error paths mroe complicated (sys_socketpair and sys_pipe), but others become simpler (sys_open)). | |||
| 2002-01-23 | Pool deals fairly well with physical memory shortage, but it doesn't deal | Artur Grabowski | |
| well (not at all) with shortages of the vm_map where the pages are mapped (usually kmem_map). Try to deal with it: - group all information the backend allocator for a pool in a separate struct. The pool will only have a pointer to that struct. - change the pool_init API to reflect that. - link all pools allocating from the same allocator on a linked list. - Since an allocator is responsible to wait for physical memory it will only fail (waitok) when it runs out of its backing vm_map, carefully drain pools using the same allocator so that va space is freed. (see comments in code for caveats and details). - change pool_reclaim to return if it actually succeeded to free some memory, use that information to make draining easier and more efficient. - get rid of PR_URGENT, noone uses it. | |||
| 2001-11-06 | Replace inclusion of <vm/foo.h> with the correct <uvm/bar.h> when necessary. | Miod Vallat | |
| (Look ma, I might have broken the tree) | |||
| 2001-10-26 | - every new fd created by falloc() is marked as larval and should not be used | Artur Grabowski | |
| any anyone. Every caller of falloc matures the fd when it's usable. - Since every lookup in the fd table must now check this flag and all of them do the same thing, move all the necessary checks into a function - fd_getfile. | |||
| 2001-09-19 | merge vm/vm_kern.h into uvm/uvm_extern.h; art@ ok | Michael Shalayeff | |
| 2001-07-05 | Get rid of unnecessary includes. | Artur Grabowski | |
| 2001-06-27 | remove old vm | Artur Grabowski | |
| 2001-06-23 | pool_init, not pool_create | Artur Grabowski | |
| 2001-06-23 | pipe_stat isn't referenced from outside sys_pipe.c anymore | Artur Grabowski | |
| 2001-06-23 | Add pipe_init, call it from main, move the pool initialization into it. | Artur Grabowski | |
| 2001-06-05 | fix kqueue EVFILT_WRITE; okay art@ | Niels Provos | |
| 2001-05-26 | Sync in some improvements from FreeBSD + my own improvements. | Artur Grabowski | |
| - use pool for allocating pipe structures. - use microtime instead of splhigh and time. - improve locking. - better handling of nonblocking. - various efficiency fixes. | |||
| 2001-05-14 | gc OLD_PIPE. | Artur Grabowski | |
| 2001-05-14 | Add a fo_stat member to struct fileops. Used soon. | Artur Grabowski | |
| Also add a stat function for kqueue from FreeBSD. | |||
| 2001-05-14 | More generic arguments to pipe_stat. | Artur Grabowski | |
| 2001-05-14 | We already have a prototype for pipe_stat in sys/pipe.h | Artur Grabowski | |
| 2001-03-01 | port kqueue changes from freebsd, plus all required openbsd glue. | Niels Provos | |
| okay deraadt@, millert@ from jlemon@freebsd.org: extend kqueue down to the device layer, backwards compatible approach suggested by peter@freebsd.org | |||
| 2000-11-16 | support kernel event queues, from FreeBSD by Jonathan Lemon, | Niels Provos | |
| okay art@, millert@ | |||
| 2000-04-19 | Change struct file interface methods read and write to pass file offset in | Constantine Sapuntzakis | |
| and out. Make pread/pwrite in netbsd & linux thread safe - which is the whole point anyway. | |||
| 2000-01-27 | No need to include sys/vmmeter.h | Artur Grabowski | |
| 1999-11-25 | Annoying unnecessary space. | Artur Grabowski | |
| 1999-11-21 | if select returns writable on a pipe, the write should not return | Theo de Raadt | |
| EWOULDBLOCK. turns out the two checking conditions were not the same, and a certain use of rsync uncovered the bug by chewing all available cpu time; fix from art | |||
| 1999-10-29 | Use M_PIPE instead of M_TEMP. | Artur Grabowski | |
| 1999-10-29 | Remove the "Direct write" code. | Artur Grabowski | |
| We never used it and some parts of it slowed the code down. Generally clean up the pipe code. | |||
| 1999-10-27 | Actually make ASYNC pipes generate SIGIO. | Niklas Hallqvist | |
| 1999-07-15 | vm_offset_t -> {v,p}addr_t ; vm_size_t -> {v,p}size_t | Artur Grabowski | |
| 1999-07-13 | introduce fdremove() to mark a file descriptor as unused. fdremove makes | Niels Provos | |
| sure that the fd_freefile hints stay in sync, otherwise free file descriptors might not be overlooked by fdalloc(); ok millert@ | |||
| 1999-06-08 | better fd leak prevention | Theo de Raadt | |
| 1999-06-07 | need seperate sys_pipe() versions, for pipeclose() or soclose() calls | Theo de Raadt | |
| 1999-06-07 | replacement pipe() system call; copies data into place inside kernel, so | Theo de Raadt | |
| that EFAULT return value is possible | |||
| 1999-06-07 | oops, premature commit | Theo de Raadt | |
| 1999-06-07 | store NULL in fd_ofiles | Theo de Raadt | |
| 1999-02-26 | kmem allocation changes for uvm | Artur Grabowski | |
| 1999-02-16 | Move defining of PIPE_NODIRECT to pipe.h and conditionalize more code with it. | Artur Grabowski | |
| This allows this code to compile on sparc. | |||
| 1997-11-06 | Updates for VFS Lite 2 + soft update. | Constantine Sapuntzakis | |
| 1997-10-06 | back out vfs lite2 till after 2.2 | Theo de Raadt | |
| 1997-10-06 | VFS Lite2 Changes | Constantine Sapuntzakis | |
| 1997-02-24 | OpenBSD tags | Niklas Hallqvist | |
| 1996-10-12 | Correct sys_pipe's 3rd arg type, alpha needs it | Niklas Hallqvist | |
| 1996-09-05 | compile! | Michael Shalayeff | |
| 1996-09-04 | Stylistic cleanup, like removing "static"s, and removing warnings | Niklas Hallqvist | |
| given by -Wall -Wstrict-prototypes -Wmissing-prototypes | |||
| 1996-08-27 | New fast pipe(2) from freebsd without fancy vm stuff. | shawn | |
| The old pipes can be used with the "OLD_PIPE" config option. | |||
