The +.I emu +display will be incorrect if the screen width available is less than 800 pixels and is not a multiple +of four. The problem can be seen if the PC is configured with a resolution of 800x600 pixels +and the Microsoft Office shortcut bar is active. The simplest fix is to change the +.I emu +shortcut to use a +.CW "-g788x600" +argument instead. +.IP \(bu +As mentioned above, the Windows NT installation program looks only for +.CW "Start Menu" +not the locale-dependent name. +.IP \(bu +Changing the cursor image does not work under Windows 2000 Client; +this mainly affects +.I acme , +which changes the cursor when rearranging or resizing frames. +.IP \(bu +The HP version of hosted Inferno was generated by HP/UX version B.10.20. +On the HP platform, +.CW emu +can currently only be run in interpreted mode; the compiled mode (ie, +.CW -c1 +option) +will fault. +.IP \(bu +Some Inferno calls return error strings provided by Windows, without modification. +They can be obscure: +for instance, ``windows error 10049'' is produced by network calls +that attempt to use symbolic names when +.I cs (8) +has not been started. +.IP \(bu +On all systems, the mapping from Inferno names and permissions to the underlying +operating system's names and permissions needs more work, particularly on Windows. +Common problems include: +.RS +.IP \- +File names in the Inferno environment cannot be longer than 27 bytes. +.IP \- +.I Ftpfs +cannot access files with long names or names containing spaces. +.IP \- +The contents of +.CW /dev/user +on Windows will contain the Windows user name, which can contain spaces. +.IP \- +Files created inside the Inferno hierarchy by host system applications +can sometimes have odd permissions when accessed within Inferno. +.IP \- +Readonly files and open files cannot be removed under Windows. +.LP +In general, the mapping between Inferno users and groups and Windows/Nt users and groups +is systematic, as described in +.I sys-stat (2): +.QS +.I Emu +attempts to maintain a limited but consistent map +between Inferno and NT worlds, specifically between Inferno +names and NT security IDs. +Special NT group `Everyone' +represents `other' for file permissions. The Inferno uid is +the file owner under NT; the Inferno gid reported is the +first user in the file's ACL that is neither the owner nor +Everyone; failing that, the gid is the file's owner. +.QE +.LP +The effects of this mapping are sometimes peculiar: for instance, something that +is thought of as a user appears as the group name in +.I ls , +and vice-versa. +Either the implementation or the mapping might need to be rethought. +.RE +.IP \(bu +.I bufio (2) +maintains an internal list of files open for output, +to support its little-used +.CW flush -all +operation. +Unfortunately, that means that if several processes +use the same Bufio module instance (the result of a single +.CW load ) +concurrently for output to different files, they must separately interlock the open, create and close calls. +.IP \(bu +The file +.CW utils/5l/thumb.c +contains comments in the C++ style, which (reasonably enough) are not accepted by the +ANSI C compiler on the HP/UX system we used, and thus the current +.CW 5l +is not compiled for HP/UX; they will be changed to ANSI C comments by +one of the online updates. +.NH 1 +Contents +.LP +This revision offers the following, compared to the July 2000 release. +.SH +.I "Repairs and changes" +.IP \(bu +Many bug fixes and improvements appear throughout. +Many commands have been revised to print usage and diagnostic consistently, and give reliable exit status for +.CW sh . +.IP \(bu +The shell +.CW sh +has repairs and several visible changes: +.I sh-expr (1) +implements a +.CW % +operator for remainder; +a new +.CW @ +operator creates a sub-shell to execute a command, allowing the calling shell to be insulated +by +.CW pctl +(see +.I sh-std (1)) +from changes to name space and environment; +environment variables are stored in printable form; +a newline is allowed after a caret; +and everyone's favourite change, the colon character +.CW : ' ` +is no longer reserved in argument words +(allowing URLs to be given without quoting). +.IP \(bu +Inferno's Acme has been revised to match the version in Plan 9 (Third Edition). +In particular, the +.CW Edit +built-in has been added, allowing the use of structural regular expressions +and the +.CW sam +command language for efficient editing within +Acme, +replacing the +.CW /acme/edit +suite of commands. +The Acme panes have acquired a similar touch of colour. +.IP \(bu +Charon has also had many fixes and improvements, particularly to +Javascript extraction, frames and layout code. +Sometimes the `fix' requires making Charon mimic the interpretation of incorrect HTML +of other browsers. +The PNG image format is now supported. +Cookies are enabled by default (too many sites use them); +parsing and production of the cookie file has been repaired. +The progress bar is more compact. +Support for longer SSL keys is enabled by default. +.IP \(bu +The software installation commands +.CW install/* +have been extensively revised, +and documented by +.I archfs (4) +and +.I create (8). +They are based (though not entirely) on Russ Cox's update +package for Plan 9. +.IP \(bu +.I format (8) +can format an ordinary file, for instance to prepare flash partition +contents in a hosted environment for a native Inferno device. +.IP \(bu +.CW mount +allows the certificate file to be named directly. +.IP \(bu +.CW ns +correctly quotes the fields in its output. +.IP \(bu +.CW /services/server/config +no longer gives the unauthenticated +.CW nobody ') (` +option to +.I styx (8); +some unused entries have also been deleted. +.IP \(bu +.I srv (8) +passes all arguments to servers it spawns, including the command name. +It also ensures each server has its own process group, file descriptors +and name space. +.IP \(bu +.I stack (1) +has a new +.CW -p +option to add names to the source file search list. +.IP \(bu +.I deflate (2) +correctly detects end-of-file; +.I inflate (2) +correctly decodes the combined compressed code-length tables +.IP \(bu +Tk's handling of objects in canvases is better: +raise and lower work properly; stipple is implemented. +.IP \(bu +Tk now knows that a window pops up when resized, and adjusts +the z-order accordingly. +.IP \(bu +Tk's scroller always expands the fraction of a +.CW moveto +when it evaluates the scrolling command. +.SH +.I "New commands and modules" +.IP \(bu +.I ftpfs (4) +provides a way to make a remote FTP site visible in the Inferno name space +(it was documented in the printed manual but not previously included with the system). +.IP \(bu +.I listen (1) +provides a convenient way to listen for incoming calls to one or more Inferno services, +with optional use of +.I ssl (3) +for authentication and encryption. +This can replace the clumsy use of +.I srv (8). +.IP \(bu +.I dial +(see +.I listen (1)) +is the complement of +.I listen ; +it dials a service, with optional authentication and encryption. +.IP \(bu +.I lockfs (4) +enforces multiple reader, exclusive writer access to the contents of a name space. +.IP \(bu +The device +.I prof (3) +serves a name space for controlling the profiling of Limbo modules, +and retrieving the resulting data. +The module +.I profile (2) +offers a convenient interface, relating the profiling data to the source code. +Finally, +.I prof (1) +is the command line interface to enable profiling and display the results. +.IP \(bu +.CW uuencode +and +.CW uudecode +interpret a format used to encode binary data printably on Usenet and in mail messages; +see +.I uuencode (1). +.IP \(bu +.I Read (1) +writes to standard output the result of a single +.I sys-read (2) +of a given number of bytes from standard input, +with optional seek offset. +(See +.I getlines +in +.I sh-std (1) +for a way to read a line from standard input.) +.IP \(bu +.I Tcs (1) +uses +.I convcs (2) +to offer character set conversion on files. +.IP \(bu +.I wm-misc (1) +mentions +.CW wm/mand , +a browser for fractals, +and +.CW wm/polyhedra , +a polyhedra viewer +.IP \(bu +.I cfg (2) +provides a module to read configuration files. +.IP \(bu +.I dividers (2) +provides user-draggable dividing lines to separate Tk widgets, +allowing screen space to be allocated to widgets by dragging a dividing line. +.IP \(bu +.I imagefile (2) +offers support for reading PNG image files +.SH +.I "Interface changes and extensions" +.IP \(bu +.CW Url +.CW /module/url.m ) ( +now requires an +.CW init +function to be invoked before other functions in the module +.IP \(bu +.I convcs (2) +has changed its interface significantly (see the manual page); +it also offers support for UTF-7. +Even the module name has changed, to +.CW Convcs +(from +.CW ConvCS ). +.IP \(bu +.I plumber (8) +now returns an error to a message's sender if it cannot be plumbed, +as was previously documented; +it handles +.CW ^ +correctly in regular expressions +.IP \(bu +.I readdir (2) +returns all file names in union directories +.IP \(bu +.I string (2)'s +quoting and unquoting functions are correct and more efficient +.IP \(bu +.I styxlib (2) +forces an internal process into a new empty name space to +allow detection of the last unmount of the served space by a file server +.IP \(bu +.I translate (2) +supports writing Unicode characters in hexadecimal using Limbo's \f5\eu\fP\fIXXXX\fP +syntax +.IP \(bu +.I workdir (2) +returns a better guess at the current directory on native Inferno +(hosted implementation will be supported in the next update) +.IP \(bu +.I cs (8) +keeps a cache of recent translations; +.I ipsrv (8) +uses UDP/IP by default, not TCP/IP, for domain name lookup +.IP \(bu +.I httpd (8) +can now be said to work as documented +.IP \(bu +.I wm-sh (1) +provides a new control file +.CW /chan/shctl +to allow it to be kept informed +of the current directory (and +.CW /lib/wmsetup +defines a Shell function to do that) +and to implement buttons below the title bar, +as with +.I mash-tk (1). +.IP \(bu +A collection of playing card images has been added in +.CW /icons/cards . +.IP \(bu +.CW /lib/wmsetup +defines a +.CW cd +function to keep +.CW wm/sh +informed of the current directory; +the +.CW Web +menu item is now called +.CW Charon ; +a new +.CW Manual +entry invokes +.I wm-man (1); +and the game +.CW Tetris +has been added to the +.CW Misc +submenu. +.IP \(bu +The manual pages +.I draw-font (2), +.I draw-image (2), +and +.I draw-screen (2) +now document +.CW display +and +.CW screen +members of various data structures. +.IP \(bu +.I security-auth (2) +and +.I security-login (2) +note that +.CW keyring.m +must be included. +.IP \(bu +In +.I sh (2), +the function +.CW exec +has been renamed +.CW run , +to reflect more accurately what it does. +.IP \(bu +In +.I sys-pctl (2), +the type of the second parameter to +.CW Sys->pctl +is actually +.CW "list of int" +not +.CW "list of ref Sys->FD" . +.IP \(bu +.I ssl (3) +documents the new +.CW encalg +and +.CW hashalg +files, which list the supported algorithms. +.IP \(bu +.I canvas (9) +describes the new +.CW -winding +option +.IP \(bu +.CW /services/cs/services +lists the Software Download Server port +and removes others that are obsolete. +.IP \(bu +.CW /services/server/config +no longer gives the unauthenticated +.CW nobody ') (` +option to +.I styx (8); +some unused entries have also been deleted. +.SH +.I "Limbo compiler" +.IP \(bu +The Limbo compiler correctly clears reference values (eg, +.CW list , +.CW ref +and +.CW array ) +when they go out of scope when necessary (eg, in loops), causing the storage to be reclaimed, +and the values to be correctly +.CW nil +when the scope is next entered. +.IP \(bu +A bug that caused temporaries sometimes to be reused too early has been fixed. +.IP \(bu +The compile-time evaluation of floating-point +.CW > +does not calculate +.CW >= +instead. +.IP \(bu +A little context has been added to `syntax error' messages. +.SH +.I "Compilers and architectures" +.IP \(bu +The system now supports the Thumb variant of the ARM architecture, +including full interworking of Thumb code and 32-bit ARM code; +there is a Thumb JIT compiler for the virtual machine, and support for +Thumb mode in the disassembler and debugger. +The Thumb compiler is +.CW tc ; +the existing ARM linker +.CW 5l +links both ARM and Thumb code. +.IP \(bu +A bug in +.CW 5l +has been fixed that could very occasionally place a literal pool inside a case table. +.IP \(bu +The compilers find include files correctly under Nt. +.SH +.I "Hosted and Native Inferno" +.IP \(bu +.I Emu +has the following fixes and improvements: +.RS +.IP \- +support for logging of memory pool usage +.IP \- +FreeBSD support uses +.I rfork +not +.I pthreads . +.IP \- +Linux support no longer relies on being able to set the TSS register. +.IP \- +A memory leak when a kernel process exits has been fixed. +.IP \- +A start has been made on tidying up the audio support; the +.CW svp.c +file has gone and platforms that do not currently support audio +no longer must include a stub driver. +.IP \- +The Linux and +FreeBSD ports use an alternative implementation of Inferno graphics +under X11 that should allow the program to run under 16-bit graphics and higher. +.RE +.IP \(bu +For the native kernels only: +.RS +.IP \- +The native kernel implements Rob Pike's `lexical names' (as in Plan 9), which helps +provide more sensible data to +.I workdir (2). +The hosted Inferno implementation of lexical names will appear in a future update. +Note that +.CW /os/port/ns.c +no longer exists, and native kernel configuration files should no longer mention +.CW ns +in the +.CW port +section. +Drivers that serve a directory hierarchy might need to support the +.CW DEVDOTDOT +value for the table index in their +.CW devgen +function. +.IP \- +.CW os/ip/bootp.c +will correctly time out if there is no response. +.CW os/ip/ihbootp.c +will now work with an RFC1084 BOOTP server. +Note that both are likely to be replaced in future by +Limbo applications that do BOOTP and DHCP. +.IP \- +.CW os/pc/cga.c +provides a replacement for +.CW screen.c +for use when only a simple CGA console is needed or possible. +.IP \- +The file descriptor array is correctly freed when the file descriptor +group is closed, fixing a memory leak. +.IP \- +A few files that were left off the July 2000 CD have been included this time. +.IP \- +ARM/Thumb kernels have been implemented; those implementations +are not included in this update because the hardware is specialised but ask if you could use them. +.RE +.LP +The remaining points are common to both hosted and native Inferno: +.IP \(bu +A write on closed pipe does not produce an exception if the process has been killed. +.IP \(bu +.I Devbwrite +will not lose memory if an error is raised by the device driver (eg, interrupt). +.IP \(bu +.I ssl (3) +has +.CW encalg +and +.CW hashalg +files +.IP \(bu +.I Kfs (3) +offers +.CW readonly +and +.CW readwrite +commands, and an +.CW ro +(readonly) +option to the +.CW init +request. +.IP \(bu +.I Srv (3) +rejects attempts to create an unusable name containing a `/'. +.IP \(bu +The +.CW NODEVS +flag of +.I sys-pctl (2) +is correctly copied when the name space is duplicated. +.\" the following is only in the 386 version +.\" .IP \(bu +.\" .I Prog (3) +.\" can optionally give the correct Dis pc for the debugger even for compiled modules; if +.\" .CW cflag +.\" (or +.\" .CW -c +.\" option for +.\" .I emu ) +.\" is 2 not 1, a mapping table is retained after JIT compilation. +.SH +.I "SA1100 native" +.IP \(bu +A new +.CW archether +function in +.CW arch*.c +(when required) +is invoked by +.CW devether.c +to discover the configuration of Ethernet devices. +.IP \(bu +.CW devuart.c +supports the use of XON/XOFF; +the first line of the +.CW stat +file gives the current UART settings; +it no longer panics if an overrun occurs; +and +.CW setlength +accesses the correct structures. +.IP \(bu +The CS8900 driver +.CW ether8900.c +is more general, supporting the I/O port interface as well as the memory interface. +.IP \(bu +Obsolete definitions have been removed from several include files +(eg, +.CW io.h ) +and obsolete (typically #ifdef'd code) has been removed from source files. +.NH 1 +IDEA™ +.LP +The software includes an implementation of the IDEA encryption algorithm, +for non-commercial use. +IDEA was patented by Ascom-Tech AG (European patent EP 0 482 154 B1, US patent number +US005214703, and patent filed in Japan). +At time of writing, there was no licence fee required for noncommercial use. +If you intend to use IDEA encryption commercially with Inferno, you should consult +.CW http://www.it-sec.com/idea_lic_policy.html +for the current licensing policy of iT_SEC Systec Ltd, which currently holds the patents and trademark. +Note that IDEA is not required for +successful use of Inferno. +It is not by default enabled by +.I rstyxd (8), +and otherwise is used only by SSL3 (for the browser), in +.CW /appl/lib/crypt/ssl3.b , +where it can be disabled. +.NH 1 +Updating the July 2000 Full Source release +.LP +A set of update packages for the July 2000 release is provided in the directory +.CW /updates +on this June 2001 CD. +You should install the updates as the host operating system user who owns the Inferno files and directories +on your system. +You might like to take a backup copy of the existing tree, just in case. +Do the following to update the installation. +(Next time we hope to provide a more automated scheme. +You might check +.CW www.vitanuova.com/inferno/ +to see if there are any more recent instructions.) +.IP 1. +Copy the directory +.CW updates +and its subdirectories from the CD to a directory +.CW updates +in the root of your existing Inferno hierarchy. +Make sure there is sufficient space in the file system holding that hierarchy. +If all platform files are copied and installed, about 45 Mbytes will be needed +to hold the compressed update packages in +.CW updates , +with a further +35 Mbytes needed for an temporary uncompressed copy +of the largest package, and allow 10 Mbytes for new additional material, giving +90 Mbytes in all. +The +.CW updates +directory can be removed after installation. +.IP 2. +Start the existing Inferno +.I emu ; +it will be quicker if you use the +.CW -c1 +option to force compiled mode. +It is best to use only the Inferno console; do not start the window system, since +the updates will change files in the running system. +On the other hand, it is a good idea to make the window in the host +operating system a scrolling one, so that you can scroll back to +see any errors. +All following commands are run in the Inferno environment. +.IP 3. +Change to the directory +.CW updates +and load the standard Inferno shell module: +.RS +.P1 +cd /updates +load std +.P2 +.RE +.NE 1i +.IP 4. +Unpack the updated installation software: +.RS +.P1 +gunzip <install.tgz | {cd /;
