System: patch version 2.0
Patch #: 11
Priority: same as patch 10
Subject: patch 10 continued
Description:
This is a new Configure.
Fix: Unlike most patches, this one contains an entire new Configure
script, which is shorter than the diffs. Unshar this file in
your patch source directory. Please make sure you've just applied
patch #10--this one doesn't check that patchlevel.h is correct.
After applying:
Configure (or Configure -d)
make
make install

X
XThis installation shell script will examine your system and ask you questions
Xto determine how the $package package should be installed. If you get stuck
Xon a question, you may use a ! shell escape to start a subshell or execute
Xa command. Many of the questions will have default answers in square
Xbrackets--typing carriage return will give you the default.
X
XOn some of the questions which ask for file or directory names you are
Xallowed to use the ~name construct to specify the login directory belonging
Xto "name", even if you don't have a shell which knows about that. Questions
Xwhere this is allowed will be marked "(~name ok)".

XMuch effort has been expended to ensure that this shell script will run
Xon any Unix system. If despite that it blows up on you, your best bet is
Xto edit Configure and run it again. Also, let me (lwall@jpl-devvax.jpl.nasa.gov)
Xknow how I blew it. If you can't run Configure for some reason, you'll have
Xto generate a config.sh file by hand.
X
XThis installation script affects things in two ways: 1) it may do direct
Xvariable substitutions on some of the files included in this kit, and
X2) it builds a config.h file for inclusion in C programs. You may edit
Xany of these files as the need arises after running this script.
X
XIf you make a mistake on a question, there is no easy way to back up to it
Xcurrently. The easiest thing to do is to edit config.sh and rerun all the
XSH files. Configure will offer to let you do this before it runs the SH files.

Saying 35- says everything from 35 to the end. You can also get the patches via anonymous FTP from jpl-devvax.jpl.nasa.gov (128.149.8.43). Just in case you had trouble with it, here's #9: mailpatch speaking for lwall System: patch version 2.0 Patch #: 9 Priority: LOW Subject: Reversed new-style context diff can cause double free(). From: lwall@sdcrdcf.UUCP Description: A new-style context diff that is reversed (-R) and that contains a hunk with an assumed old or new half is not freed properly. When there is a hunk-half assumed, the lines are duplicated internally by copying the pointers of the actual lines from the other half. A pair of variables then tell the freeing routine not to free that range of fake lines since they will be freed when the other half hunk is freed. The problem is that the routine that swaps halves of the hunk didn't update the variables to point to where the fake lines were moved to. Fix: From rn, say "| patch -d DIR", where DIR is your patch source directory. Outside of rn, say "cd DIR; patch <thisarticle". If you don't have the patch program, apply the following by hand, or get patch. If patch indicates that patchlevel is the wrong version, you may need to apply one or more previous patches, or the patch may already have been applied. See the patchlevel.h file to find out what has or has not been applied. In any event, don't continue with the patch. If you are missing previous patches they can be obtained from me: Larry Wall {allegra,burdvax,cbosgd,ihnp4,sdcsvax}!sdcrdcf!lwall If you send a mail message of the following form it will greatly speed processing: Subject: Command @SH mailpatch PATH patch 2.0 LIST ^ note the c where PATH is a return path FROM ME TO YOU in bang notation, and LIST is the number of one or more patches you need, separated by spaces, commas, and/or hyphens.
