this package includes all those changes too. +.NH 1 +Contents +.LP +This update offers the following, compared to the 28 June 2002 update. +.LP +The main change is that the Plan 9 hosted implementation supports Plan9 Fourth Edition. +This has affected the portability interface for both hosted and native software. +That, and the introduction of `lexical names' into +.I emu +causes this update to be classified as `experimental'. +.LP +The following sections provide short +summaries of the more interesting or important changes. +There are many more minor or cosmetic changes. +.SH +.I "New commands and modules" +.SH +.I "Repairs and changes" +.IP \(bu +.CW cp +has been reworked extensively; amongst other things, it can now safely traverse +arbitrary name spaces without becoming confused by +complex mounts. +.IP \(bu +.I Listen (1) +and +.CW dial +both accept a +.CW -A +option to cause it to authenticate a connection. +.IP \(bu +.I Diff (1) +compares binary files and also does not quit (during recursive diffs) when it finds +a file it cannot open. +.IP \(bu +.I Ls (1) +implements the +.CW -u +and +.CW -t +sorting operations properly. +A new +.CW -e +option prints the time as a decimal integer (seconds since the system Epoch). +.IP \(bu +.I Sh +regards all of `../', `./', and `#' at the front of a command name as a request to use the name as-is. +.IP \(bu +.I Tail +has been changed to avoid some boundary cases. +.IP \(bu +.I Touch +uses standard argument processing and returns an error exit status if it fails. +.IP \(bu +.I Zeros +accepts new options +.CW -r +to generate random bytes +and +.CW -v +to produce blocks with a given value. +.IP \(bu +The network games software in +.CW /appl/games +uses port 6660 for its signer, not the standard Inferno signer's port. +.IP \(bu +.I Charon : +disguises itself as Mozilla to satisfy agent-name probes; retries fetches on error; supports multiple windows; +detects HTML vs plain text correctly; has many Javascript fixes, including fixing a day one bug +in operator precedence (!). +In general, it +has undergone extensive changes, +particularly to the cookies and Javascript implementation. +It also insists that it be run under the window manager +.I wm (1). +It can be set to plumb schemes that it does not implement internally. +.IP \(bu +The installation software now uses the numeric time as-is to name output packages; +the temporary fix introduced in Ocotober of converting leading +.CW 10 +to +.CW A +has been removed. +.IP \(bu +.CW /appl/lib/dis.b +prints offsets from +.CW MP +correctly (it previously printed them +as offsets from +.CW FP ). +.IP \(bu +.CW /appl/lib/parseman.b +accounts for enough extra +.I troff +commands to display +.I man (6) +correctly. +.IP \(bu +.CW /appl/lib/profile.b +binds +.CW #P +only if needed. +.IP \(bu +.CW /appl/lib/translate.b +.I translate (2)) ( +now computes the right hash value. +.IP \(bu +Several run-time checks that were missing or incomplete for array access and slicing have been added. +.IP \(bu +.CW lib/isrv +no longer starts a new shell. +.IP \(bu +.I Wm-ftree (1) +has several new options: +.CW -E , +.CW -p +and +.CW -d . +.IP \(bu +.CW wm/rt +now correctly updates stack size (if set). +.IP \(bu +.I Xd (1) +correctly implements +.CW -r +to suppress repeated lines. +.IP \(bu +.I gettar (1) +documents the +.B lstar +output format +.IP \(bu +.I man (6) +describes the manual page documentation format +.SH +.I "Interface changes and extensions" +.IP \(bu +.I Security-password (2) +provides a new entry +.CW setpwfile +to allow the default name +.CW /keydb/password +to be changed. +.IP \(bu +.I Dossrv (4) +has changed extensively, to support rename and long names in FAT format correctly. +It uses a smaller number of IO buffers. +.IP \(bu +.I Createsignerkey (8) +has a completely different invocation, documented in that manual page, +with a conventional option structure replacing a rather idiosyncratic chain +of optional arguments. +The old syntax is temporarily secretly still supported, but only +for the benefit of any shell scripts that might so use it; if you have any, +please change them to use the new syntax before the old usage finally vanishes in a later release. +.IP \(bu +.I Sum (1) +documents the new +.CW sha1sum +command. +.IP \(bu +.I Bufio (2) +returns an error if a seek fails rather than stopping the process(!). +.IP \(bu +.CW /lib/convcs +has several more character sets: +.CW koi8-r , +.CW windows-1250 +and +.CW windows-1252 . +.IP \(bu +.I Keyring-sha (2) +documents two new functions, +.CW hmac_sha1 +and +.CW hmac_md5 , +which are keyed versions of the corresponding secure hashing functions, +as defined by RFC2104. +The new definitions are in +.CW /module/keyring.m . +.IP \(bu +.I Keyring-getstring (2) +makes it clear that it does not +.I provide +delimited I/O but rather +.I requires +it (eg, as provided by +.I ssl (3)) +for successful operation. +.IP \(bu +.I Security-ssl (2) +no longer requires +.CW #D +to be bound into the name space (since it can only be used locally in any case). +Consequently, +.CW bind +calls have been removed from several modules that used SSL. +.IP \(bu +.CW /appl/lib/crypt/ssl3.b +has several critical bug fixes, allowing secure connections to work correctly in Charon; +an important bug fix was also made to +.CW /appl/lib/crypt/x509.b . +.IP \(bu +.I Imageremap +has been changed to allow concurrent use. +.IP \(bu +.I Translate (6) +and +.CW /appl/lib/translate.b +have changed as required to put the locale-specific dictionaries in directory +\f(CW/locale/\fP\fIlocale\f(CW/dict\fP; +the directory for a chosen +.I locale +is then normally bound onto +.CW /locale/dict , +where +.CW translate +looks by default. +.IP \(bu +The documentation for +.I button (9) +no longer claims that +.CW -padx +and +.CW -pady +are supported options for that widget. +.IP \(bu +.CW sys.m +has some new constants defined for use by a later Styx revision. +.SH +.I "Tk changes and extensions" +.IP \(bu +The canvas code provides extensions to Tk: +.CW "grab set tag" , +.CW "grab release tag" , +and +.CW "grab ifunset tag" . +See +.I canvas (9) +for details. +.IP \(bu +Also in canvases, object-specific hit tests have been added, rather than using a bounding box +in most cases. +.IP \(bu +Borderwidth defaults to zero in the entry widget. +.IP \(bu +Tk multiplexes the cursor amongst top-level windows. +.IP \(bu +Text and other items selected use foreground/background colours +.SH +.I "Limbo compiler" +.IP \(bu +Constant tuple and adt values can be used as values in +.CW con +constant declarations. +.IP \(bu +In an array value, the use of reference values for different +.CW pick +alternatives of the same adt no longer draws a diagnostic +but causes the array value to be an array of +.CW ref +to the adt, not a particular pick alternative. +.IP \(bu +The C language stub declarations support +.CW pick +adts. +.IP \(bu +The alignment of +.CW big +and +.CW real +is now correct in C stubs. +.IP \(bu +The string escape +.CW \ef +is form-feed (to simplify translation of C programs). +.SH +.I "Compilers and utilities" +.IP \(bu +.I Iar 's +source directory has been renamed from +.CW ar +to +.CW iar . +.IP \(bu +.CW mk +understands the long-name table in Windows' archive files, preventing +spurious out-of-date status and other confusing results in builds. +.IP \(bu +.CW sqz +and +.CW zqs +can compress larger ARM and PowerPC executables. +.IP \(bu +.CW kprof +uses a table now provided by +.CW /dev/kprof +to provide profiling results to the resolution selected by a given platform. +.SH +.I "Hosted and Native Inferno" +.LP +Changes common to hosted and native kernels: +.IP \(bu +The +.CW HOSTMODEL +and +.CW TARGMODEL +for Plan 9 are now +.CW Plan9 +not, rather confusingly, +.CW Inferno . +A good few source files have been renamed accordingly. +.IP \(bu +The memory allocation functions have been modified slightly to support the addition of +memory monitoring and profiling. +Some functions have also been added to the C library supporting +.I emu +and the kernels, +with an eye to starting the revision of Styx, based on the current 9P2000. +Consequently, the +include file +.CW lib9.h +for all platforms has been modified: +to add new functions such as +.CW setmalloctag ; +to make the types of parameters to the +.CW malloc +calls uniform (and reflect the documentation, as it happens), +so that sizes are always unsigned; +to change the type of a parameter to +.CW strchr +and +.CW strrchr +from +.CW char +to +.CW int ; +to remove obsolete definitions such as +.CW UMFILE +and +.CW UMDIR ; +and to add new functions for use inside the kernels. +Several new functions are strictly for internal use +(and thus might change in future), and +they have not been added to section 10. +One exception is the new function +.CW tokenize , +documented in +.I getfields (10.2) +and used by +.I parsecmd (10.2). +.I Getfields +replaces the function called +.CW parsefields , +which has been removed, and all calls to it changed to use +.CW getfields . +The higher aim of some of these otherwise fussy changes is +to work towards making Inferno and Plan 9 drivers interchangeable +(as best we can). +.IP \(bu +To help decouple authentication methods from identity setting, two new files +.CW caphash +and +.CW capuse +have been added to +.CW #c +(a temporary location for them), supported by code in +.CW auth.c +.CW /os/port/auth.c ). ( +Their use will soon replace the +.CW setid +functionality of +.I keyring-auth . +They will not be documented until then. +.IP \(bu +.CW /emu/exception.c +and +.CW /os/port/exception.c +no longer trap the use of the +.CW exit +statement (by accident of implementation). +.CW \(bu +.CW /emu/dis.c +and +.CW /os/port/dis.c +do not leave a process in Broken state when it +receives an exception because a kernel memory allocation failed. +.IP \(bu +The JIT compilation of case statements has fixed a day one bug +that caused a degenerate form of +.CW case +(with only a default arm) to be compiled incorrectly. +.IP \(bu +The 386 JIT will allow rescheduling, and the scheduling is finer grained on the ARM. +.IP \(bu +ARM code generation produces correct code for some list accesses that were previously wrong +(the Dis operator HEADM) +.IP \(bu +.I Emu +has the following changes specific to it: +.RS +.IP \- +The mouse event queue in +.CW devcon.c +is now a circular queue without locks as in the native kernel; +this prevents a scheduling problem under Linux. +.IP \- +The +.CW READSTR +constant defined by the native kernels is now also defined by +.CW emu . +.IP \- +The function previously called +.CW rendezvous +is now called +.CW erendezvous +to avoid a type clash with a library function on Plan 9 +(its `rendezvous' function takes an unsigned long as first parameter, not +.CW void* ). +.CW lib9.h +has changed accordingly where required. +.IP \- +.CW devcon.c +acquires +.CW caphash +and +.CW capuse . +.IP \- +A new file +.CW auth.c +must be included in every build. +.IP \- +Several drivers in +.CW emu +have been changed to use +.RS +.P1 + switch((ulong)c->qid.path ...) +.P2 +.RE +to force 32-bit operations to be used when +.CW path +eventually becomes 64 bits. +.IP \- +Also in +.CW emu +the function +.CW oserrstr +now takes a buffer length, rather than assuming +.CW ERRLEN . +.IP \- +Obsolete code for time and directory mode conversions (!) has been removed from +.CW os-*.c . +.IP \- +Obsolete code for `daemonize' has been removed from +.CW os-*.c +and +.CW lib9 . +.RE +.IP \(bu +For the native kernels: +.RS +.IP \- +.CW /os/port/devprof.c +has been added but is not yet supported (it is not configured in to any kernel, +so no existing kernels are affected by its presence). +.IP \- +.CW /os/port/devcons.c +has +.CW caphash +and +.CW capuse +.IP \- +Every kernel configuration file must now include +.CW auth +in the +.CW port +section to include +.CW /os/port/auth.c . +.RE +...#.bp +...#.NH 1 +...#Description by source file +...#.LP +...#.TS
