cca96a509cfe Import from CVS: tag r20-1b12

663 lead to the keyboard being "control-locked"--ordinary letters are

964 This typically happens on Suns and other systems that use shared
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
965 libraries. The cause is that the site has installed a version of the
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
966 shared library which uses a name server--but has not installed a
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
967 similar version of the unshared library which Emacs uses.
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
968
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
969 The result is that most programs, using the shared library, work with
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
970 the nameserver, but Emacs does not.
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
971
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
972 The fix is to install an unshared library that corresponds to what you
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
973 installed in the shared library, and then relink Emacs.

977 If you have already installed the name resolver in the file libresolv.a,
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
978 then you need to compile Emacs to use that library. The easiest way to
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
979 do this is to add to config.h a definition of LIBS_SYSTEM, LIBS_MACHINE
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
980 or LIB_STANDARD which uses -lresolv. Watch out! If you redefine a macro
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
981 that is already in use in your configuration to supply some other libraries,
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
982 be careful not to lose the others.
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
983
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
984 Thus, you could start by adding this to config.h:
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
985
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
986 #define LIBS_SYSTEM -lresolv
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
987
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
988 Then if this gives you an error for redefining a macro, and you see that
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
989 the s- file defines LIBS_SYSTEM as -lfoo -lbar, you could change config.h
376386a54a3c Import from CVS: tag r19-14
cvs
parents:

990 again to say this:

1213 1) Record the names of all the .elc files.
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1214 2) Delete all the .elc files.
376386a54a3c Import from CVS: tag r19-14
cvs

1215 3) Recompile alloc.c with a value of PURESIZE twice as large.
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1216 You might as well save the old alloc.o.
376386a54a3c Import from CVS: tag r19-14
cvs

1217 4) Remake xemacs. It should work now.
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1218 5) Running xemacs, do Meta-x byte-compile-file repeatedly
376386a54a3c Import from CVS: tag r19-14
cvs
parents:

1219 to recreate all the .elc files that used to exist.
376386a54a3c Import from CVS: tag r19-14

376386a54a3c Import from CVS: tag r19-14
cvs

1223 6) Reinstall the old alloc.o (undoing changes to alloc.c if any)
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1224 and remake temacs.
376386a54a3c Import from CVS: tag r19-14
cvs
parents:

1225 7) Remake xemacs. It should work now, with valid .elc files.

parents:
diff changeset
1232
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1233 This could be caused by
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1234 1) adding code to the preloaded Lisp files
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1235 2) adding more preloaded files in loadup.el
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1236 3) having a site-init.el or site-load.el which loads files.
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1237 Note that ANY site-init.el or site-load.el is nonstandard;
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1238 if you have received Emacs from some other site
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1239 and it contains a site-init.el or site-load.el file, consider
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1240 deleting that file.
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1241 4) getting the wrong .el or .elc files
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1242 (not from the directory you expected).
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1243 5) deleting some .elc files that are supposed to exist.
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1244 This would cause the source files (.el files) to be
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1245 loaded instead. They take up more room, so you lose.
376386a54a3c Import from CVS: tag r19-14

1246 6) a bug in the Emacs distribution which underestimates
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1247 the space required.

diff changeset
1248
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1249 If the need for more space is legitimate, use the --puresize option
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1250 to `configure' to specify more pure space.
376386a54a3c Import from CVS: tag r19-14

parents:
diff changeset
1251
376386a54a3c Import from CVS: tag r19-14
cvs
parents:

1252 But in some of the cases listed above, this problem is a consequence
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1253 of something else that is wrong. Be sure to check and fix the real
376386a54a3c Import from CVS: tag r19-14

1258 You may have forgotten to recompile them into .elc files.
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1259 Then the old .elc files will be loaded, and your changes
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1260 will not be seen. To fix this, do M-x byte-recompile-directory
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1261 and specify the directory that contains the Lisp files.

376386a54a3c Import from CVS: tag r19-14

1263 Note that you may get a warning when loading a .elc file that

1269 The fonts of the "bold" and "italic" faces are generated from the font of

cvs
parents:

1270 the "default" face; in this way, your bold and italic fonts will have the

cvs
parents:

376386a54a3c Import from CVS: tag r19-14
cvs

1356 used. C-s/C-q flow control is bad for Emacs editors because it takes
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1357 away C-s and C-q as user commands. Since editors do not output long

1361 input characters without interference. Designing such a mechanism is

1365
376386a54a3c Import from CVS: tag r19-14

1366 1) Terminal has not been told to disable flow control
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1367 2) Insufficient padding for the terminal in use
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1368 3) Some sort of terminal concentrator or line switch is responsible
376386a54a3c Import from CVS: tag r19-14

parents:
diff changeset
1369
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1370 First of all, many terminals have a set-up mode which controls whether
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1371 they generate XON/XOFF flow control characters. This must be set to
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1372 "no XON/XOFF" in order for Emacs to work. Sometimes there is an
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1373 escape sequence that the computer can send to turn flow control off
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1374 and on. If so, perhaps the termcap `ti' string should turn flow
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1375 control off, and the `te' string should turn it on.

1376
376386a54a3c Import from CVS: tag r19-14
cvs
parents:

1377 Once the terminal has been told "no flow control", you may find it
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1378 needs more padding. The amount of padding Emacs sends is controlled
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1379 by the termcap entry for the terminal in use, and by the output baud
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1380 rate as known by the kernel. The shell command `stty' will print
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1381 your output baud rate; `stty' with suitable arguments will set it if
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1382 it is wrong. Setting to a higher speed causes increased padding. If
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1383 the results are wrong for the correct speed, there is probably a
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1384 problem in the termcap entry. You must speak to a local Unix wizard
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1385 to fix this. Perhaps you are just using the wrong terminal type.

1391 If you are really unlucky, your terminal is connected to the computer
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1392 through a concentrator which sends XON/XOFF flow control to the
376386a54a3c Import from CVS: tag r19-14

1394 much padding you give it. Unless you can figure out how to turn flow

1398 measures can make Emacs semi-work.

1413 IMPORTANT: if you type C-s by accident while flow control is enabled,
376386a54a3c Import from CVS: tag r19-14
cvs

1414 Emacs output will freeze, and you will have to remember to type C-q in

1485 The first step in tracking this down is to record what characters
376386a54a3c Import from CVS: tag r19-14
cvs

1486 Emacs is sending to the terminal. Execute the Lisp expression

cvs

1487 (open-termscript "./emacs-script") to make Emacs write all terminal

1490 using the manual for the terminal. There are several possibilities:

cvs

1520 Often the termcap entry for the type of terminal in use fails
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1521 to inform Emacs of this. The two lines at the bottom of the screen
376386a54a3c Import from CVS: tag r19-14
cvs

1522 before a Control-V command are supposed to appear at the top after
376386a54a3c Import from CVS: tag r19-14
cvs
parents:

1523 the Control-V command. If Emacs thinks scrolling the lines is fast,
376386a54a3c Import from CVS: tag r19-14
cvs

1524 it will scroll them to the top of the screen.

1525
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1526 If scrolling is slow but Emacs thinks it is fast, the usual reason is
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1527 that the termcap entry for the terminal you are using does not
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1528 specify any padding time for the `al' and `dl' strings. Emacs
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1529 concludes that these operations take only as much time as it takes to
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1530 send the commands at whatever line speed you are using. You must
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1531 fix the termcap entry to specify, for the `al' and `dl', as much
376386a54a3c Import from CVS: tag r19-14
cvs

1532 time as the operations really take.

1533
376386a54a3c Import from CVS: tag r19-14
cvs

1534 Currently Emacs thinks in terms of serial lines which send characters
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1535 at a fixed rate, so that any operation which takes time for the
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1536 terminal to execute must also be padded. With bit-map terminals
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1537 operated across networks, often the network provides some sort of
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1538 flow control so that padding is never needed no matter how slow
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1539 an operation is. You must still specify a padding time if you want
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1540 Emacs to realize that the operation takes a long time. This will
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1541 cause padding characters to be sent unnecessarily, but they do
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1542 not really cost much. They will be transmitted while the scrolling
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1543 is happening and then discarded quickly by the terminal.

376386a54a3c Import from CVS: tag r19-14

1545 Most bit-map terminals provide commands for inserting or deleting
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1546 multiple lines at once. Define the `AL' and `DL' strings in the
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1547 termcap entry to say how to do these things, and you will have
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1548 fast output without wasted padding characters. These strings should
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1549 each contain a single %-spec saying how to send the number of lines
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1550 to be scrolled. These %-specs are like those in the termcap

376386a54a3c Import from CVS: tag r19-14

376386a54a3c Import from CVS: tag r19-14
cvs

1554 has a command to insert or delete multiple characters. These
376386a54a3c Import from CVS: tag r19-14

1588 There was a serious pair of bugs in the handling of the fsync() system

1589 call in the RFS server.

376386a54a3c Import from CVS: tag r19-14

1591 The first is that the fsync() call is handled as another name for the
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1592 close() system call (!!). It appears that fsync() is not used by very
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1593 many programs; Emacs version 18 does an fsync() before closing files
376386a54a3c Import from CVS: tag r19-14

1597
376386a54a3c Import from CVS: tag r19-14
cvs
parents:

1598 The second, more serious problem, is that fsync() is treated as a
376386a54a3c Import from CVS: tag r19-14
cvs
parents:
diff changeset
1599 non-blocking system call (i.e., it's implemented as a message that
376386a54a3c Import from CVS: tag r19-14

1787 1. The ld in IRIX 5.3 ignores all but the last -rpath

1794 2. IRIX gcc 2.7.2 doesn't accept -rpath directly, so

9f59509498e1 Import from CVS: tag r20-1b10
cvs
parents: 88
