Thu Aug 13 11:15:24 1998  Noel Cragg  <noel@swish.red-bean.com>

	* version.c: Change version number to 1.10 and name to `Halibut'.

	* sanity.sh (rcslib): new tests to check behavior of symlinks in
 	the repository.

Wed Aug 12 15:39:38 1998  Noel Cragg  <noel@swish.red-bean.com>

	* main.c (lookup_command_attribute): the `annotate' command
 	shouldn't require access to the repository.  Add comment about
 	commands that do not use the working directory.

Mon Aug 10 10:26:38 1998  Noel Cragg  <noel@swish.red-bean.com>

	* version.c: Change version number to 1.9.30.

Thu Aug  6 17:44:50 1998  Noel Cragg  <noel@swish.red-bean.com>

	* server.c (serve_rdiff): change the name of the command (for
 	error reporting, etc.) from "patch" to "rdiff."
	(serve_remove): rename from "cvsremove" to "remove."

	* main.c (lookup_command_attribute): the `rdiff' command shouldn't
 	require write access to the repository.

1998-08-06  David Masterson of kla-tencor.com
	and Jim Kingdon

	* commit.c (commit_filesdoneproc): Don't call strlen ("CVSROOT")
	from within the assert statement.  Apparently HP's cc compiler on
	HPUX 10.20 has trouble with that.

1998-08-06  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* rcs.c (RCS_checkin): When adding branch, if there is a lock on
	the branchpoint owned by someone else, leave it alone.  This
	restores CVS 1.9 (RCS 5.7) behavior, fixing a core dump.
	* sanity.sh (reserved): New tests reserved-16 through reserved-19
	test for this fix.

1998-08-05  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* sanity.sh (unedit-without-baserev): Use ${QUESTION} not "?".
	This makes it work with GNU expr 1.12 as well as 1.16.

Sun Aug  2 20:27:44 1998  Noel Cragg  <noel@swish.red-bean.com>

	* mkmodules.c: add comment about TopLevelAdmin for the initial
 	contents of CVSROOT/config.

1998-07-29  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* rcs.c (RCS_checkin): Only try to call xreadlink if HAVE_READLINK
	is defined.

Tue Jul 28 19:33:08 1998  Noel Cragg  <noel@swish.red-bean.com>

	* version.c: Change version number to 1.9.29.

	* rcs.c (RCS_checkin): add code to follow symbolic links in the
 	repository.

Sun Jul 26 05:14:41 1998  Noel Cragg  <noel@swish.red-bean.com>

	* This set of changes reverts the code to pre-1.9.2 behavior and
 	does not create CVS directories at top-level (except for the
 	obvious "cvs co .").  Added a new configuration option to switch
 	between 1.9 and 1.9.2 behavior.
	
	* recurse.c (do_argument_proc): new function.
	(start_recursion): in the case that we've done a command from
 	top-level but have no CVS directory there, the behavior should be
 	the same as "cvs <cmd> dir1 dir2 dir3...".  Make sure that the
 	appropriate "Argument" commands are sent to the server by calling
 	walklist with do_argument_proc.
 
	* client.c (call_in_directory): only create the top-level CVS
 	directory when we're checking out "." explicitly.  The server will
 	force creation of this directory in all other cases.

	* checkout.c (checkout_proc): only generate the top-level
 	directory when the TopLevelAdmin=yes.  Also send a message to the
 	client to do the same.

	* parseinfo.c (parse_config): handle TopLevelAdmin option.  Set
 	top_level_admin.

	* main.c: add new variable top_level_admin.
	* cvs.h: add extern definition for above.

	* sanity.sh: since we're reverting to pre 1.9.2 behavior for
 	top-level CVS directories, I needed to make changes to a bunch of
 	tests that made assumptions about said directories.
	(preamble): make sure to add read and execute access to everything
 	in TMPDIR before removing, since some tests make things read-only.
	(basicb-1a, basicb-1b, basicb-9a, basicb-9b): use dotest_fail
 	because these tests check for the non-existant top-level CVS
 	directory.
	(basicc-3, emptydir-6, emptydir-7, crerepos-6): use "rm -rf" so it
 	won't complain when trying to remove the non-existant top-level
 	CVS directory.
	(106.5): remove imported-f2-orig.tmp.
	(modules2-10, emptydir-4, abspath-1ba, abspath-1bb): cd into the
 	directory where files exist before using the "add" command so cvs
 	can find CVSROOT in CVS/Root.
	(cvsadm-2): look at a different CVS/Repository file, since the
 	top-level one doesn't exist.
	(taginfo-3): create the directory in the repository directly
 	rather than relying on the fact that the top-level CVS directory
 	was created in a previous test.
	(serverpatch-6): update first-dir explicity, rather than relying
 	on the non-existant top-level CVS/Entries file.
	(crerepos-18): look at CVS/Repository in a subdirectory rather
 	than in the non-existant top-level CVS directory.
	(toplevel): add code to set TopLevelAdmin=yes.
	(toplevel2): new tests -- same as toplevel, but TopLevelAdmin=no.

1998-07-21  Jim Meyering  <meyering@ascend.com>

	* rcs.c (RCS_checkout): Hoist frees of rev and value.
	Warn and return 1 in several cases rather than exiting via
	`error (1, ...'.  The latter could abort a multi-file commit
	in mid-stream, leaving stale locks in the repository.

1998-07-16  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* build_src.com (rcscmds.c): Also look for include files in
	[-.diff], just like Ian's 1998-06-18 change to Makefile.in

1998-07-14  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* tag.c (pretag_proc), rtag.c (pretag_proc): Don't pass RUN_REALLY
	to run_exec.  This means that taginfo does not get executed if the
	global -n option is specified.  Which makes it like loginfo, -i,
	-e, -o, -t, -u in modules, editinfo, and verifymsg and unlike
	commitinfo.  The old behavior was pretty bad in the sense that it
	doesn't provide any way to log only the tags which actually
	happen.
	* sanity.sh (taginfo): New tests taginfo-11 to taginfo-13, for this.

1998-07-12  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* sanity.sh (ann-id): Write the test so that it tests for the
	current (buggy) behavior.

	* sanity.sh (taginfo): Also clean up cvsroot/first-dir.

1998-07-12  Jim Meyering  <meyering@ascend.com>

	* sanity.sh (ann-id): New (currently failing) test for bug in how
	rcs keywords are expanded in the output of `cvs annotate'.

1998-07-12  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* sanity.sh (taginfo): Write the TESTDIR into the script rather
	than having the script look at the environment.  This means that
	it will work if TESTDIR is set by sanity.sh as well as if
	sanity.sh finds TESTDIR in the environment.

1998-07-11  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* tag.c (check_fileproc): Calculate the revision to be tagged the
	same way that tag_fileproc does.
	* sanity.sh (taginfo): New tests, test for this (before this fix,
	brtag had said 1.1 not 1.1.2.1).

1998-07-10  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* sanity.sh (unedit-without-baserev): Also clean up "2" directory.

1998-07-08  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* edit.c (unedit_fileproc): If the Baserev file is missing, don't
	get the working file from CVS/Base.  The previous code could get
	you version 1.1 of the working file and put 1.2 in CVS/Entries.
	* sanity.sh (unedit-without-baserev): New tests test for this.

1998-07-02  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* sanity.sh (unedit-without-baserev): Move the test itself to be
	in the same order as in the "tests" variable.

1998-07-02  Ian Lance Taylor  <ian@cygnus.com>

	* rcscmds.c: Don't include <stdarg.h> or <vasprintf.h>.  Don't
	declare vasprintf.
	(call_diff_printf_output): Remove.
	(call_diff_stdout_callbacks): Don't initialize printf_output
	field--it has been removed from the interface.
	(call_diff_file_callbacks): Likewise.

1998-07-01  Jim Meyering  <meyering@ascend.com>

	* edit.c (unedit_fileproc): Handle the case in which base_get
	returns a NULL baserev.  That happens when a file being `unedit'ed
	exists in the CVS/Base directory, but isn't listed in the CVS/Baserev
	file.  The one case I've seen had no Baserev file at all.  The symptom
	(if you're lucky) is a segmentation fault upon unedit.  If you use
	SunOS4.1.4 for which printf prints NULL pointers as `(null)', your
	unedit command will complete normally, but it will have corrupted
	your CVS/Entries file and a subsequent update may result in an
	assertion failure, a core dump, and a stale lock in the repository.
	* sanity.sh (unedit-without-baserev): New test for this.

1998-07-01  Andy Mortimer of aeat.co.uk
	and Jim Kingdon  <kingdon@harvey.cyclic.com>

	* server.c (server_updated): Use a prototype if we are using them
	for declarations.

1998-06-29  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* sanity.sh (commit-readonly): Protect keyword against expansion
	in sanity.sh itself.  Keep the keyword in the file which we check
	in (or else this fails to test for the RCS_checkout change).

1998-06-27  Jim Meyering  <meyering@ascend.com>

	* rcs.c (RCS_checkout): If opening the local workfile fails due to
	lack of write access, try to chmod the file and retry the open.
	Before, a commit could fail part way through merely because the
	open to rewrite with newly expanded rcs keywords would fail.  It's
	easy to make this happen if you use `cvs -r' or CVSREAD and you
	apply a patch to one of your read-only source files -- patch
	preserves the read-only setting for the file and your next commit
	will fail after committing that file, but before rewriting
	(checking out) your working copy.
	* sanity.sh (commit-readonly): New test for this.

1998-06-25  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* update.c (patch_file): Update comments regarding context diffs
	to reflect diff library.

1998-06-23  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* sanity.sh (modules4): Add tests for reversing the order of the
	"!first-dir/sdir" and "first-dir".

1998-06-23  Jim Kingdon  <kingdon@harvey.cyclic.com>
	and Dave Wolfe@Motorola.

	* sanity.sh (modes2): Touch the file before chmod'ing it.

1998-06-21  Ian Lance Taylor  <ian@cygnus.com>

	* update.c (merge_files): Revert changes of 1998-06-19.  Instead,
	register a merged file with a dummy time stamp.  Only set
	last_register_time if we need to.
	(join_file): Likewise.  Always register a merged file, not just
	when the merge fails.

1998-06-21  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* call_diff_write_output, call_diff_printf_output,
	call_diff_flush_output, call_diff_write_stdout, call_diff_error,
	call_diff_stdout_callbacks, call_diff_file_callbacks): Re-indent.

1998-06-19  Ian Lance Taylor  <ian@cygnus.com>

	* update.c (merge_file): Make sure the time stamp of the file is
	different from the time stamp we register in the Entries file.
	(join_file): Likewise.

1998-06-18  Wilfredo Sanchez  <wsanchez@apple.com>

	* checkin.c: change rename_file if wrapper to copy_file. rename
	fails when the source file (/tmp/cvsXXX) is on a different device
	than the destination (typically your home dir), which is often the
	case. The source file gets cleaned up later so unlinking it causes
	a not found error message anyway.

1998-06-18  Ian Lance Taylor  <ian@cygnus.com>

	* rcscmds.c: Include <stdio.h>.  Include either <stdarg.h> or
	<varargs.h>.  Declare vasprintf.
	(call_diff_write_output): New static function.
	(call_diff_printf_output): New static function.
	(call_diff_flush_output): New static function.
	(call_diff_write_stdout): New static function.
	(call_diff_error): New static function.
	(call_diff_stdout_callbacks): New static variable.
	(call_diff_file_callbacks): New static variable.
	(call_diff): Don't sleep.  Use a callback structure when calling
	the diff library.
	(call_diff3): Likewise.

	* rcscmds.c: Include diffrun.h.
	(call_diff, call_diff3): Pass NULL callback parameter.
	(diff_run, diff3_run): Don't declare.
	* Makefile.in (rcscmds.o): New target, to use -I for diff
	directory.
	(zlib.o): Depend upon zlib.h.

1998-06-09  Mike Sutton@SAIC

	Make it compile with Sun's bundled K&R C compiler:
	* rcs.c (count_delta_actions): Change to static to match
	declaration.
	* client.c (handle_wrapper_rcs_option): Rename error label to
	handle_error to avoid clash with function name.

1998-06-09  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* rcs.c (RCS_delete_revs): If we are trying to delete all
	revisions, give an error rather than assertion failed.
	* sanity.sh (basicb): New tests basicb-o* test for this.

1998-06-04  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* add.c (add): Only send "Directory" requests if we need to.

1998-06-02  Assar Westerlund  <assar@sics.se>

	* client.c: Check for HAVE_GSS_C_NT_HOSTBASED_SERVICE rather than
	assuming that GSS_C_NT_HOSTBASED_SERVICE is a macro.
	* server.c: Likewise.

1998-06-02  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* fileattr.c (fileattr_read): Check for NULL return from strchr.
	* sanity.sh (devcom3): New test devcom3-10 checks for this.

1998-06-01  Assar Westerlund  <assar@sics.se>
	and Ian Lance Taylor  <ian@cygnus.com>

	* client.c: If HAVE_GSSAPI_H, include <gssapi.h>.  Only include
	<gssapi/gssapi.h> if HAVE_GSSAPI_GSSAPI_H.  Only include
	<gssapi/gssapi_generic.h> if HAVE_GSSAPI_GSSAPI_GENERIC_H.
	(GSS_C_NT_HOSTBASED_SERVICE): Define if not defined.
	(connect_to_gserver): Use GSS_C_NT_HOSTBASED_SERVICE instead of
	gss_nt_service_name.
	* server.c: Same header file changes.
	(GSS_C_NT_HOSTBASED_SERVICE): Define if not defined.
	(gserver_authenticate_connection): Use GSS_C_NT_HOSTBASED_SERVICE
	instead of gss_nt_service_name.

1998-06-01  Jim Meyering  <meyering@ascend.com>

	* sanity.sh (tag8k): Add a test for the 1998-05-02 rcs.c bug fix.

1998-05-26  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* rcs.c (annotate): Call tag_check_valid like the other functions
	which have a -r option.
	* sanity.sh (ann): New test ann-14 tests for this.

1998-05-24  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* sanity.sh (importc): New tests importc-5 through importc-8 test
	for a (fairly obscure) regression from CVS 1.9.

1998-05-23  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* sanity.sh (modules2): Add comment listing cvs release tests.
	(info): New test info-cleanup-0 tests "cvs -n release".

	* rcs.c (rcsbuf_getid): Remove semicolon at end of #undef.  I'm
	kind of surprised that compilers accepted this at all, but
	removing it squelches a warning for some compilers.

	* version.c: Change version number to 1.9.28.1.

	* Version 1.9.28.

1998-05-22  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* rcs.c (RCS_cmp_file): Check for errors from CVS_FOPEN.  This
	restores the CVS 1.9 behavior (fatal error if we can't open the
	file), and corrects an apparent oversight in Ian's 13 Apr 1997
	change.
	* sanity.sh (modes2): New test, tests for this.

1998-05-22  Ian Lance Taylor  <ian@cygnus.com>

        * server.c (server_updated): Correct test for whether to unlink
        the file.

1998-05-20  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* wrapper.c (wrap_add): Disable -t/-f wrappers at least until the
	serious bug can be fixed.

1998-05-15  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* checkout.c (checkout): Call server_pathname_check on the
	argument to "cvs co -d".
	* server.c (server_pathname_check): Add comment about how we could
	be handling absolute pathnames.
	* sanity.sh (abspath): Rewrite the tests which run "cvs co -d /foo"
	for remote, to reflect this.

	* sanity.sh (abspath): Also do the "cannot rename" work-around for
	abspath-7d.

1998-05-13  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* commit.c (commit_filesdoneproc): Free admin_dir when done with it.

1998-05-13  Jim Meyering  <meyering@ascend.com>

	* sanity.sh (editor): Change bogus sed command, `s/^/x&/g', to `s/^/x/'.
	The former exercised a bug in GNU sed-3.01-beta3.
	(emptydir-8): Add `Rebuilding administrative file database' message,
	since now it does that.
	* commit.c (commit_filesdoneproc): Pass only the admin directory
	pathname to mkmodules.
	Remove #if 0, now that it's fixed.

	* status.c (cvsstatus): Rename from `status' to avoid shadowing
	lots of locals and parameters by the same name.
	* server.c (serve_status): Update caller.
	* main.c (cmds[]): Update table entry.
	* cvs.h: Update prototype.

	* commit.c (commit_filesdoneproc): Remove trailing blanks.
	(commit) [CLIENT_SUPPORT]: Remove unnecessary (and local-shadowing)
	declaration of `err'.
	Rename global `tag' to `saved_tag' to avoid overshadowing `tag'
	parameters of three functions.
	Rename global `message' to `saved_message' to avoid overshadowing
	`message' parameter of a function.
	Rename global `ulist' to `saved_ulist' and move dcl up with others.

1998-05-12  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* commit.c (commit_filesdoneproc): #if 0 the new code until it can
	be fixed.

	* commit.c (commit_filesdoneproc): Add comment explaining last
	change.

1998-05-12  Jim Meyering  <meyering@ascend.com>

	* commit.c (commit_filesdoneproc): Call mkmodules not just when
	committing a file directly under CVSROOT, but also when committing
	files in subdirectories of CVSROOT.

1998-05-08  Jim Meyering  <meyering@ascend.com>

	* filesubr.c (xreadlink):  NUL-terminate the symbolic link name.
	Use a much smaller initial buffer length.
	Test errno only if readlink fails.
	Use xstrdup then free the original link name so we don't waste space.

1998-05-02  Jim Meyering  <meyering@ascend.com>

	* rcs.c (rcsbuf_getword): Fix off-by-one error that would result in
	an abort (the first one in rcsbuf_getkey) when operating on on some
	,v files with over 8192 bytes of tag and branch info.

1998-05-04  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* sanity.sh (ann): New tests ann-12 and ann-13 test for specifying
	a numeric branch.

1998-05-02  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* rcs.c: Add comments about getting rid of rcsbuf_getid,
	rcsbuf_getword, and rcsbuf_getstring.

	* sanity.sh (abspath): Revise the workarounds to deal with exit
	status.

1998-04-30  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* sanity.sh (abspath): Work around the "cannot rename" bug.

1998-04-27  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* classify.c (Classify_File): Add comments about checking whether
	command name is "update".

1998-04-22  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* version.c: Change version number to 1.9.27.1.

	* Version 1.9.27.

1998-04-20  Jim Kingdon  <kingdon@harvey.cyclic.com>

	(This diff was run by devel-cvs and everyone seemed to like it).
	* diff.c (diff_file_nodiff): Make HEAD mean the head of the branch
	which contains the sticky tag, not the sticky tag itself.
	* rcs.c, rcs.h (RCS_branch_head): New function.
	* sanity.sh (head): Update for this changed behavior.

1998-04-19  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* sanity.sh: Move emptydir tests from basicb to new test emptydir.
	This is because we now need a module definition to create Emptydir;
	"co -d" doesn't cut it anymore.

1998-04-17  Petri Virkkula

	* server.c (mkdir_p): Ignore EROFS error (like for EACCES).

1998-04-16  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* checkout.c (checkout_proc): Don't create directories above the
	last one specified in "co -d".
	(build_dirs_and_chdir): Revert Noel's change of 17 Feb 1998.
	(struct dir_to_build): New field just_chdir.
	(build_dirs_and_chdir): Test it.
	* sanity.sh (abspath): New tests abspath-7* test for a bug which
	we fix, in which CVS would create bogus "D/////" entries in
	CVS/Entries.
	(abspath): Revise abspath-3* tests to test for the fact that we no
	longer create directories above the last one specified in "co -d".
	I checked that CVS 1.9 gives an error on this, so changing this
	behavior back should be OK.
	(cvsadm-2d3): Likewise (also checked CVS 1.9 for this case).
	(cvsadm-2d3d): Likewise (also checked CVS 1.9 for this case).
	(cvsadm-2d{4,5,6,7,8}, cvsadm-N2d{3,4,5,6,7,8}): Adjust for new
	behavior (same case as cvsadm-2d3).
	(cvsadm-2d{4,5,6,7,8}d, cvsadm-N2d{3,4,5,6,7,8}d): Remove test
	(same case as cvsadm-2d3d).
	(cvsadm): For remote, skip most these tests.
	(abspath): When cleaning up, delete mod1 and mod2 rather than mod1
	twice (longstanding bug, apparently only becomes visible if you
	run the tests in a certain order).

1998-04-14  Wilfredo Sanchez  <wsanchez@apple.com>

	* rcs.c: variable "lockfile" was being referenced after being
	free'd.  Bad.  Moved the free() call down.

1998-04-12  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* sanity.sh (rcs): Add test for annotate and the year 2000.

	* server.c (do_cvs_command): If there are partial lines left when
	the child process is done, send them along.
	* sanity.sh (rcs, rcs2): Enable all tests for remote; tests for
	this fix.

1998-04-11  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* client.c (client_senddate): Pass SDATEFORM not DATEFORM to
	sscanf.  This fixes a Y2K bug.

	* history.c (history, select_hrec): Change since_date from time_t
	to RCS format.  Use the usual machinery (in particular, Make_Date
	and client_senddate) so that it will work on VMS too.
	* main.c, cvs.h (date_from_time_t): New function.
	* sanity.sh (history): New test, to test that this didn't break
	anything (also tests client_senddate fix).

1998-04-11  Norbert Kiesel  <nk@iname.com>

	* server.c (cvs_output_binary): Shut up "gcc -Wall" by removing
	unnecessary else if test.
	* server.c (check_password): Fix uninitialized memory read if
 	shadow passwords are used.  Also added some comments.
	* rcs.c (RCS_checkout): Make sure to call chown with -1 for uid or
	gid if they should not be changed

1998-04-10  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* sanity.sh (rcs2): New test, tests for various Y2K cases.
	* rcs.c (getdelta): Value for "state" keyword is optional (bug
	discovered incidentally in writing rcs2 test).

1998-04-09  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* filesubr.c, cvs.h (link_file): Remove; no longer used.

1998-04-08  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* recurse.c (do_dir_proc): Restore update_dir rather than a
	computation which appears to, but does not necessarily, restore it
	(reported by various people; this fix is from Greg Hudson).
	* sanity.sh (importc): New test, tests for this fix.

1998-03-27  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* rcs.c (RCS_lock): If the revision is already locked, give an
	error rather than dumping core.
	* sanity.sh (reserved): New test reserved-13c tests for this.

1998-03-25  Loren J. Rittle

	* import.c (add_rev): Rewrite to use RCS_FLAGS_KEEPFILE option
	of RCS_checkin() to avoid damage to imported files instead of
	externally undoing damage after the fact.  The side effect is
	that callers of add_rev() may now incrementally walk the
	entries of the current directory without seeing gratuitous
	changes to the directory structure (under at least one file
	system under at least one OS).

1998-03-18  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* error.c (error): Save and restore errno.  Should fix test case
	conflicts3-23 on SCO 5.0.2.  Reported by Steve Cameron.

	* sanity.sh (admin): Rename admin-26-o* to admin-26-*; the "o"
	stands for "cvs admin -o".  Add comment about length of tests.
	Use ${PLUS}.

1998-03-05  Dan Wilder <dan@gasboy.com>

 	* Fix problem with cvs admin in which -ntag:branch
 	option associated tag with the branch's head revision.
 	Should have used branch number.  Entailed in this fix,
 	the following.

 	* Add new functions "RCS_exist_rev", "RCS_exist_tag",
 	"RCS_tag2rev", and "RCS_valid_rev" to rcs.c.  RCS_tag2rev
 	is similar to RCS_gettag, but does less interpretation.

 	* Plug a small memory leak.

 	* Add tests admin-26 through admin-29 to sanity.sh,
 	to test "cvs admin -n".

1998-03-17  Samuel Tardieu  <sam@inf.enst.fr>

	* server.c (server_register): protect dereferencing timestamp in
	the trace message when it is null, to avoid a segmentation fault.

1998-03-16  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* options.h.in (MY_NDBM): Rewrite the comment explaining this
	option.  It was not clear to everyone who "my" referred to, for
	example.

	* hardlink.c (list_linked_files_on_disk): Remove unused variables
	err and p.
	(list_linked_files_on_disk): Add comment about memory allocation
	of return value.
	* rcs.c (rcsbuf_getword): Shut up gcc -Wall with a "return 0".
	(RCS_checkin): Remove unused variable fullpath.
	* sanity.sh (hardlinks): Remove comment about spurious warnings;
	the warnings are gone.

1998-03-12  Tim Pierce  <twp@skepsis.com>

	(rcsbuf_getid, rcsbuf_getstring, rcsbuf_getword): New functions.
	(getdelta): Call them, storing `hardlinks' field in vnode->hardlinks.
	(RCS_reparsercsfile): When setting rdata->desc, xstrdup value
	rather than rcsbuf_valcopying it (due to changes in how getdelta
	handles keys and values in newphrases).

	* sanity.sh (hardlinks): Use uglier filenames.  Checking out
	hardlinked files no longer produces the same spurious diagnostics,
	so fix that test.
	(hardlinks-2.3): Renamed from hardlinks-2.2 (duplicate test name).

	New infrastructure for managing hardlink lists internally...
	* hardlink.c, hardlink.h (list_linked_files_on_disk,

	Removed.
	* hardlink.h: Removed `links' member from hardlink_info struct.
	* commit.c (commit): Remove the call to cache_hardlinks_proc.
	(check_fileproc) [PRESERVE_PERMISSIONS_SUPPORT]: Removed reference
	to hlinfo->links.
	* hardlink.c (update_hardlink_info): Same.
	* update.c (get_linkinfo_proc): Same.

	* rcs.c (RCS_checkout) [PRESERVE_PERMISSIONS_SUPPORT]: Use
	vp->hardlinks and find_checkedout_proc to find recently-updated
	files that may be hardlinked.
	* update.c (special_file_mismatch): Use List * structures and
	compare_linkage_lists for rev1_hardlinks and rev2_hardlinks.

1998-03-16  Larry Jones  <larry.jones@sdrc.com>

	* server.c (check_password): If shadow passwords are supported but no
	entry is found in the shadow file, check the regular password file.

1998-03-07  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* sanity.sh: Rename permissions test to perms since that is what
	each of its individual tests are named.
	* sanity.sh (perms symlinks hardlinks): Change CVSROOT to
	CVSROOT_DIRNAME where appropriate.
	(perms symlinks hardlinks): Disable/adjust the meat of the tests for
	remote.
	(symlinks): Link to ${TESTDIR}/fumble rather than
	/fumble/mumble/grumble.  We shouldn't be making assumptions about
	what might exist in random directories outside ${TESTDIR}.
	* hardlink.c (cache_hardlinks_proc): Add comment about trimming
	whitespace.

1998-03-07  Tim Pierce  <twp@skepsis.com>

	* rcs.c (RCS_checkout): Negation bug when checking out symlinks:
	existence_error should be !existence_error.
	* sanity.sh (permissions symlinks hardlinks): New tests, for
	PreservePermissions.

1998-03-04  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* version.c: Change version number to 1.9.26.1.

	* Version 1.9.26.

	* entries.c, cvs.h (Entries_Open): New argument update_dir; use it
	in error message.
	* add.c, checkout.c, client.c, find_names.c, import.c, recurse.c,
	update.c: Pass it (as NULL except in call_in_directory).
	* entries.c (Subdirs_Known): Just return if there is no CVSADM
	directory (as in subdir_record).
	* sanity.sh (conflicts3): New tests conflicts3-20a and
	conflicts3-23 test for these fixes.

	* commit.c (commit): Only set up hardlist if preserve_perms.

	* commit.c, import.c, no_diff.c, parseinfo.c, rcs.c, rcscmds.c,
	update.c: Omit the preserve_perms code if
	PRESERVE_PERMISSIONS_SUPPORT is not defined.  Much of that code
	won't even compile on non-unix systems.

	* hardlink.c, hardlink.h: Use the 'standard' copyright (as found
	in server.c).
	* commit.c, rcs.c: Minor whitespace changes to Tim's submission.
	* commit.c (check_fileproc), update.c (get_linkinfo_proc): Remove
	unused variable delta.
	* hardlink.c (set_hardlink_field_proc), update.c
	(get_linkinfo_proc): Return a value rather than falling off the
	end of the function.

1998-03-02  Tim Pierce  <twp@skepsis.com>

	* update.c (special_file_mismatch): Compare the hard links of the
	two revisions.

	* rcs.c (RCS_checkout):

	* hardlink.c, hardlink.h: New files.
	(hardlink_info): New struct.

	(OBJECTS): Add hardlink.o.
	(HEADERS): Add hardlink.h.

	* rcs.c: Include hardlink.h.
	(RCS_checkin): Save list of hardlinks in delta node.

	(get_linkinfo_proc): New function.
	(do_update): Extra recursion to collect hardlink info.
	(special_file_mismatch): Reparse the RCS file if necessary.

	* find_names.c (fsortcmp): Removed.
	* lock.c (fsortcmp): Removed.

1998-03-03  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* sanity.sh (conflicts3): New tests conflicts3-14a,
	conflicts3-14b, and conflicts3-21, conflicts3-22 test that we can
	skip over a working directory with a CVSADM directory missing.

1998-02-26  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* sanity.sh (conflicts3): Tests conflicts3-16 and conflicts3-20
	test that we include update_dir in messages.  Rename test
	conflicts3-14 to fix typo.

Sun Feb 22 23:14:25 1998  Steve Cameron  <steve.cameron@compaq.com>
	and Ian Lance Taylor  <ian@cygnus.com>

	* update.c (tag_update_dir): New static variable.
	(update_dirent_proc): If no tag or date were specified when
	creating a subdirectory, use the tag and/or date of the parent
	directory.

	* update.c (patch_file): If the revision is dead, let
	checkout_file handle it.
	* sanity.sh (death2): Add test for above patch: add
	death2-10a, death2-10b, death2-13a, and adjust
	death2-{2,4,5,11,14,diff-11,diff-12,19}.

	* cvs.h (RCS_FLAGS_KEEPFILE): Define.
	* rcs.c (RCS_checkin): If RCS_FLAGS_KEEPFILE is set in the flags
	parameter, don't unlink the working file.
	* checkin.c (Checkin): Don't copy the file.  Instead pass
 	RCS_FLAGS_KEEPFILE to RCS_checkin, and only check the file out
	again if it has changed.

1998-02-21  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* rcs.c (rcs_internal_unlockfile, RCS_rewrite): Don't assume errno
	means anything just because ferror is set.

Sat Feb 21 20:02:24 1998  Ian Lance Taylor  <ian@cygnus.com>

	* Makefile.in (clean): Change "/bin/rm" to "rm".

	* buffer.c (buf_append_buffer): Correct typo in comment.
	* rcs.c (RCS_putadmin): Likewise.

Fri Feb 20 17:53:06 1998  Ian Lance Taylor  <ian@cygnus.com>

 	because ferror is true.

1998-02-20  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* sanity.sh (abspath): Don't assume that we can't write to /; this
	is the kind of thing that is sure to break sooner or later
	(especially on Windows).

	* sanity.sh: Add summary of which modules tests are which (at
	"modules").  Move cvsadm, abspath, and toplevel next to modules.
	Add comments to clarify the structure (such as it is).

Fri Feb 20 12:47:14 1998  Larry Jones  <larry.jones@sdrc.com>

	* admin.c (admin_fileproc): Better fix for -b.

	* rcs.c (RCS_whatbranch): Back out previous change.

	for errors from fopen properly.

Wed Feb 18 16:03:37 1998  Larry Jones  <larry.jones@sdrc.com>

	* admin.c (admin_fileproc): Convert -b argument from symbolic name
	to revision number before storing in the RCS file.
	* rcs.c (RCS_whatbranch): Allow numeric as well as symbolic revision.
	(RCS_getversion): Take advantage of above.
	* sanity.sh (admin): Add/revise/renumber admin-10c, admin-11a,

	* commmit.c (lock_RCS): Minor clean-up.

	* sanity.sh (abspath-6a): Don't depend on the sepcific contents of

	* rcs.c (putsymbol_proc): Use putc and fputs rather than fprintf.
	(RCS_putadmin): Don't call RCS_symbols if the symbols have not yet
	been converted to a list.

	* rcs.c (rcsbuf_cache, rcsbuf_cache_open, rcsbuf_cache_close): New
	static functions to avoid closing and reopening the RCS file.
	(cached_rcs, cached_rcsbuf): New static variables.
 	(RCS_parse): Call rcsbuf_cache_close.  Don't call fclose.
	(RCS_parsercsfile): Likewise.
	(RCS_parsercsfile_i): Call rcsbuf_cache rather than
	rcsbuf_close.  Call fclose on error.  Remove comment about
	inefficiency of opening file twice.
	(RCS_reparsercsfile): Call rcsbuf_cache_open rather than fopen and
	rcsbuf_open.  Call rcsbuf_cache rather than rcsbuf_close and
	fclose.
	(RCS_fully_parse, RCS_checkout, RCS_deltas): Likewise.
	(RCS_rewrite): Likewise.
	(RCS_checkin): Call rcsbuf_cache_close.

	* rcs.c (RCS_copydeltas): Fix code which checks for an extra
	newline in buffered data.

	* rcs.c (rcsbuf_getkey): Save an indirection by using start rather
	than *valp when trimming trailing whitespace from value.

	* rcs.c (rcsbuf_get_buffered): New static function.
	(RCS_copydeltas): After we have done all the required special
 	actions, and inserted any new revision, just copy the file bytes
 	directly, rather than interpreting all the data.
	(count_delta_actions): New static function.
	* sanity.sh (rcs): Add rcs-6a and rcs-6b to commit a new branch
	revision, to force CVS to interpret all the data, rather than just
	copying it.  Adjust rcs-5 to add a branch tag.  Adjust rcs-8a and
	rcs-14 for the changes created by rcs-6b.

Tue Feb 17 18:34:01 1998  Ian Lance Taylor  <ian@cygnus.com>

	* sanity.sh (cvsadm, diffmerge2): Remove directories at the end of
	the test.

	* import.c (expand_at_signs): Rewrite to use memchr and fwrite
	rather than putc.

	Rewrite RCS file reading routines for speed:
	* rcs.c (struct rcsbuffer): Define.
	(rcsbuf_open, rcsbuf_close, rcsbuf_getkey, rcsbuf_getrevnum,
	rcsbuf_fill, rcsbuf_valcopy, rcsbuf_valpolish,
	rcsbuf_valpolish_internal, rcsbuf_ftell): New static functions.

	new parameters.

1998-02-17  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* sanity.sh (toplevel): Also clean up second-dir (not a new
	bug, but triggered by running tests as "toplevel abspath").

	* create_adm.c (Create_Admin): Just print update_dir to tell the
	user where we are; not the whole xgetwd.  Cleaner than
	Noel's change (which also had problems in errno handling).
	* sanity.sh (toplevel-12): Update accordingly.

Tue Feb 17 02:32:21 1998  Noel Cragg  <noel@swish.red-bean.com>

	[These mods make "checkout" work with "-d /absolute/pathname"
	once again.]

	* checkout.c (checkout_proc): the -d flag on the command line
 	should override the -d flag in the modules file if the latter is
 	an absolute path.  The loop that assembles the list of directories
 	to build has been reorganized slightly to prepare for rewriting
 	with last_component rather than assuming '/' as a path separator.
  	Also added to that loop was some code to handle absolute
 	pathnames.
	(build_dirs_and_chdir): add a new argument that tells this routine
 	whether or not to check before it creates and populates
 	directories or not.

	* filesubr.c (last_component): return the top-level directory when
 	asked about the top-level directory.

	* sanity.sh (toplevel-12): change test to reflect the new style of
 	this error message.

	* create_adm.c (Create_Admin): include the directory in the error
 	message.

1998-02-16  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* diff.c (diff_fileproc), import.c (import, add_rcs_file), rcs.c
	(RCS_cmp_file): Don't ignore errors from CVS_UNLINK and fclose.

	* patch.c (patch_fileproc): Check for errors from fclose; if we
	get -1 from getline check for end of file vs. error.

	* rcs.c (RCS_checkout): Comment return value (0/1, not -1).
	* commit.c, diff.c, mkmodules.c, patch.c, rcs.c, update.c: Update
	to match this convention.  Don't suppress errors based on
	quiet or really_quiet variables.

	Fix a longstanding bug which also makes stamps-8kw in make
	remotecheck work again (it stopped working with Ian's 8 Feb 98
	checkin):
	* client.c, client.h (change_mode): If new argument respect_umask
	is set, then honor the umask.
	* client.c, server.c: Update callers.

	Cleanups to Tim's checkin:
	* rcs.c (RCS_checkout): Use existence_error not ENOENT.
	* commit.c (checkaddfile): Remove comment about whether we want to
	check for errors from fclose; there is no reason not to.
	* rcs.c (RCS_checkout), update.c (special_file_mismatch): sscanf
	on %ld requires an unsigned long, not a dev_t.
	* update.c (special_file_mismatch): Remove unused variable
	check_devnums.
	* mkmodules.c (config_contents): Between two settings, use a blank
	line not a "#" line.

1998-02-15  Tim Pierce  <twp@skepsis.com>

	[This is the code as submitted.  I'll be checking in my cleanups
	shortly.  This work sponsored by Abbott Labs.  -kingdon]

	Support for device special files, symbolic links, user and group
	ownerships, and file permissions.

	* parseinfo.c: (parse_config): Handle new config variable
	`PreservePermissions'.
	* mkmodules.c (config_contents): Add new PreservePermissions var.

	* rcs.c, rcs.h (preserve_perms): New variable.
	(RCS_checkout, RCS_checkin): Support for newphrases `owner',
	`group', `permissions', `special', `symlink'.
	(RCS_checkout): If `workfile' and `sout' are symlinks, remove them
	before attempting to open them for writing.
	* import.c (add_rcs_file): Support for newphrases.  Do not attempt
	to read data from special files or symlinks.  Error message
	`cannot fstat' is now `cannot lstat'.

	New metrics for deciding when two files are different:

	* update.c, cvs.h (special_file_mismatch): New function.
	(merge_file, join_file): Call it.
	* no_diff.c (No_Difference): Call it.

	* filesubr.c (xcmp): Consider files to be different if they are of
	different types; if they are symlinks which link to different
	pathnames; or if they are devices with different device numbers.
	Error message is now `cannot lstat'.
	* rcs.c (RCS_cmp_file): Use `xcmp' to compare files, simplifying
	the special handling for nonregular files.

	* rcscmds.c (diff_exec, diff_execv): If asked to obtain diffs for
	special files, report no differences.

	Miscellaneous changes to make special file support possible:

	* commit.c (fix_rcs_modes): Don't attempt to `fix' permissions on
	a symlink.

	* import.c (add_rcs_file): Don't try to close fpuser if it was
	never opened (e.g. when operating on a symlink).

	* filesubr.c, cvs.h (isdevice, xreadlink): New functions.
	* filesubr.c (copy_file): Handle special files and symlinks.
	(xchmod): Do nothing if `preserve_perms' is set.

	* commit.c (checkaddfile): Replace `copy_file (DEVNULL, ...)' with
	fopen/fclose calls.  Copy_file no longer attempts to read data
	from device files.

	* filesubr.c (islink): Use CVS_LSTAT, not lstat.
	* vers_ts.c (time_stamp, time_stamp_server): Use CVS_LSTAT, not stat,
	to get symlinks right.
	* subr.c (get_file): Same.  Don't attempt to read from special
	files or symlinks.

	* classify.c (Classify_File): Doc fix.

Fri Feb 13 17:07:32 1998  Eric Mumpower  <nocturne@cygnus.com>
	and Ian Lance Taylor  <ian@cygnus.com>

	Fix some file system ordering problems found on Irix 6.4:
	* sanity.sh (basic2): Use dotest_sort for test 56.
	(importb): Use dotest_sort for tests importb-1 and importb-2.
	(head): Use dotest_sort for test head-1.

Thu Feb 12 15:15:33 1998  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* import.c (add_rcs_file): If add_logfp is NULL, don't call fperror.

11 Feb 1998  Andy Piper

	* server.c (cvs_output_binary): Use OPEN_BINARY not _O_BINARY.

Wed Feb 11 23:32:45 PST 1998  Wilfredo Sanchez  <wsanchez@apple.com>

	* Makefile.in: Change bindir, etc. to get values from configure
	(eg. @bindir@) instead of figure it out inthe Makefile.

	* Makefile.in: Add TAR = @tar@

	* Makefile.in: Change $(INSTALL) to $(INSTALL_PROGRAM) in install:
	target to get proper mode bits.

	* client.c: Added b.bum's client/server wrapper code, and then
	did come cleanup on it. The code is not 100% there yet, but it's a
	good start, and I think we're not doing anything bogus like hardcoding
	paths, etc. Note that in the actual transfer code, it's wrapped with
	noexec=0 (and reverts afterwards) so that the tar to allow cvs -nq update
	to pass the tar file back and forth for	comparison. I think some minor
	tweaking can get this functionality to be happy for once.

	* cvs.h: add define for CVSWRAPPERTMP.

	* options.h.in: add #define WRAPPERS_USE_TAR_FOR_TRANSFER

	* options.h.in: add define for TAR_PROGRAM.

	* rcs.c: variable "lockfile" was being referenced after being free'd. Bad.
	Moved the free() call down.

	* server.c: Added b.bum's client/server wrapper code, and then did come
	cleanup	as above with client.c.

	* server.h: Moved server_active outside of #ifdef SERVER_SUPPORT because
	it is used outside of SERVER_SUPPORT in server.c.

	* update.c: Added patch from "unofficial patches" which fixes a bug whereby
	after adding a new file to a branch, commits go to the main branch, not the
	branch you added to. Patch was slightly modified to deal with change in
	ParseTag().

	* wrapper.c: Added b.bum's client/server wrapper code, and then did come
	cleanup	as above with client.c.

Mon Feb  9 18:34:39 1998  Jim Kingdon  <kingdon@harvey.cyclic.com>

	Tweaks to Ian's checkin:
	* update.c (merge_file): Remove comment about sending file to
	client before the message.  It doesn't apply to this code any more
	(it does apply to checkout_file, but I'm not sure it is important
	to have such a comment anyway).
	* buffer.c (buf_default_memory_error, buf_length): Reindent.
	* server.h: Declare struct buffer before use.

Mon Feb  9 21:05:28 1998  Ian Lance Taylor  <ian@cygnus.com>

	* rcs.c (RCS_fully_parse): Call getrevnum rather than getrcsrev.
	Don't bother with ungetc.

	* rcs.c (getrcsrev): Rewrite to simply call getrevnum.

Sun Feb  8 15:49:39 1998  Ian Lance Taylor  <ian@cygnus.com>

	Don't have the server check out a revision into a file and then
	immediately read the file; just read into a buffer instead.
	* update.c: Include buffer.h.
	(update_fileproc): Let checkout_file call server_updated.
	(checkout_file): Add merging and update_server parameters.  Change
	all callers.  If server_active, don't mess with backup files.  If
	server_active, copy the revision into a buffer rather than a file
	when possible.  If update_server, call server_updated.  Fix
	handling of error status.
	(checkout_to_buffer): New static function used by checkout_file.
	(merge_file): Let checkout_file call server_updated.
	(join_file): Likewise.
	* server.c (server_updated): Change file_info parameter to mode
	parameter.  Add filebuf parameter.  Change all callers.  If
	filebuf is not NULL, don't read the file.
	* server.h (server_updated): Update declaration.
	* buffer.c (buf_free): New function.
	(buf_append_buffer): New function.
	(buf_length): New function.
	* buffer.h (buf_free, buf_append_buffer, buf_length): Declare.

	* buffer.c: (buf_initialize): If the memory parameter is NULL, use
	buf_default_memory_error.
	(buf_default_memory_error): New static function.
	* buffer.h (BUFMEMERRPROC): Define typedef.
	* client.c (buf_memory_error): Remove.
	(start_server): Pass NULL rather than buf_memory_error as buffer
	memory error function.

Sat Feb  7 16:27:30 1998  Ian Lance Taylor  <ian@cygnus.com>

	* rcs.c (RCS_parsercsfile_i): Read the expand keyword from the RCS
	file.  We do this because Version_TS calls RCS_getexpand in many
	common cases, and we don't want to reopen the file just for that.
	(RCS_reparsercsfile): Skip the expand keyword.
	(RCS_getexpand): Don't call RCS_reparsercsfile.

	* rcs.c (STREQ): New macro.  In all string equality tests in the
	file, replace strcmp with STREQ.

Fri Feb  6 16:14:49 1998  Ian Lance Taylor  <ian@cygnus.com>

	* update.c (checkout_file): If we've already removed the backup
	file once, don't try to remove it again.

	* filesubr.c (unlink_file_dir): Call stat rather than isdir, and
	don't call unlink if the file does not exist.

	* myndbm.c (mydbm_load_file): Rename line_len to line_size.  Call
	getstr rather than getline, to avoid any confusion between \n and
	\012.  Use the line length returned by getstr rather than calling
	strlen.  Remove local variable len.

Fri Feb  6 13:23:46 1998  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* rcs.c (RCS_parsercsfile_i): Don't suppress errors on
	really_quiet.
	(RCS_parsercsfile_i, RCS_reparsercsfile, RCS_fully_parse,
	RCS_deltas, getdelta, getrcskey, RCS_getdeltatext):
	Check for errors.  Include errno in error messages.  Include
	filename in error messages.  Pass new argument to getrcskey.
	(getrcskey): New argument NAME, so we can report errors ourself.

Fri Feb  6 12:10:18 1998  Ian Lance Taylor  <ian@cygnus.com>

	* rcs.c (RCS_reparsercsfile): Don't use ftell/fseek; just keep
	track of whether we've already read a key/value pair.  Use sizeof
	rather than strlen for a constant string.  Pass the current key
	and value to getdelta, and get them back as well.
	(getdelta): Add keyp and valp parameters.  Don't use ftell/fseek;
	just return the key/value pair to the caller.  Don't allocate
	vnode before we know we need it.  Check one getrcskey return
	value.  Use sizeof rather than strlen for a constant string.

	* rcs.c (getrcskey): Correct comment describing return value.

Thu Feb  5 22:51:13 1998  Ian Lance Taylor  <ian@cygnus.com>

	* subr.c (getcaller): Cache the result, so that we don't keep
	searching the password file.

Wed Feb  4 23:31:08 1998  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* rcs.c (max_rev): Don't prototype.  Interesting that noone
	complained about this until now.

4 Feb 1998  Jim Kingdon

	* rcs.c (RCS_checkin): When adding a new file, read it
	with "rb" if binary.

Fri Jan 30 11:32:41 1998  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* sanity.sh: Also test "first-dir" as the regexp in loginfo in
	addition to ALL.

	* main.c (main): Update year in copyright notice to 1998.

Thu Jan 29 00:01:05 1998  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* version.c: Change version number to 1.9.25.

	* Version 1.9.24.

	* sanity.sh (multibranch2): File file2 and tests multibranch2-13
	through multibranch2-15 test a slightly different case than the
	rest of multibranch2.

	* mkmodules.c (cvswrappers_contents): Rewrite.  The text didn't
	describe -k and had various other problems.

28 Jan 1998  Karl Fogel and Jim Kingdon

	New feature to let server tell client about wrappers.
	* client.h (struct response): Add comment about args being
	'\0' terminated when passed to handle_* functions.
	* client.c (start_server): send "wrapper-sendme-rcsOptions" to
	server iff supported.
	(responses): new response "Wrapper-rcsOption"; allows the server
	to send certain lines from its cvswrappers file.
	(handle_wrapper_rcs_option): new func, handles "Wrapper-rcsOption"
	response from server.
	* server.c (serve_wrapper_sendme_rcs_options): new func, sends
	server side CVSROOT/cvswrappers rcs option lines to client.
	(requests): new request "wrapper-sendme-rcsOptions"; if received,
	we know we can send "Wrapper-rcsOption..." to the client.
	* wrapper.c (wrap_unparse_rcs_options): new func; repeated calls
	step down the wrapper list returning rcs option entries, but
	repackaged as cvswrappers lines.
	(wrap_setup): new guard variable `wrap_setup_already_done'; if
	this function has run already, just return having done nothing.
	Add comment concerning environment variable.
	* cvs.h: declare wrap_unparse_rcs_options().

Tue Jan 27 18:27:19 1998  Ian Lance Taylor  <ian@cygnus.com>

	* rtag.c (rtag_dirproc): Call ignore_directory, and skip the
	directory if it returns true.
	* sanity.sh (modules4): New set of tests to test some aspects of
	excluding directories in the modules file, including the above
	patch.

Thu Jan 22 10:05:55 1998  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* server.c (serve_kopt): Check for length of arg.  Based on
	inspection of the code, plugs a buffer overrun security hole which
	was introduced Monday.

	* server.c (serve_is_modified): Don't call xmalloc; we aren't
	allowed to call error() here.  Remove duplicate (and potentially
	confusing) variable 'p'.

	* log.c (log_fileproc): Look for first character of version
	'0' AND second character '\0', rather than OR.  I didn't try to
	come up with a test case but this looks like a simple thinko
	(albeit one which would show up in obscure cases if at all).

Tue Jan 20 19:37:53 1998  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* client.c (send_dirent_proc): Don't send nonexistent directories
	unless noexec.
	* sanity.sh (modules2): New tests modules2-13 through modules2-18
	test for this fix.

Mon Jan 19 11:17:51 1998  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* server.c (serve_kopt): New function.
	(requests): Add "Kopt" request.
	(kopt): New variable.
	(serve_is_modified): Write kopts from there into entries.
	(serve_modified): Call serve_is_modified so we do the same.
	Declare serve_modified and serve_is_modified.
	* vers_ts.c (Version_TS): Set ->options even for a dummy ("D"
	timestamp) entry.
	* import.c (process_import_file): Check for -k options.
	* client.c (client_process_import_file): Send Kopt request.
	(send_fileproc): Likewise, for "cvs add".
	* sanity.sh: Enable test binwrap3-sub2-add1 for remote.
	Add -I .cvswrappers to binwrap3-2a; adjust binwrap3-2d
	accordingly.  Tests for this fix.

Mon Jan 19 08:48:59 1998  Larry Jones  <larry.jones@sdrc.com>

	* sanity.sh (errmsg1): Append test 168 output to log file.

Sat Jan 17 08:01:51 1998  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* sanity.sh (ann-10, ann-11): Don't make assumptions about the
	number of characters in the username.

Fri Jan 16 15:34:02 1998  Larry Jones  <larry.jones@sdrc.com>

	* diff.c (diff_fileproc): Free label1 and label2 when finished.

	* edit.c (editor_set): Don't free edlist until after we're
	done using it.

	* rcscmds.c (RCS_merge): Free xrev1 and xrev2 when finished.

	* subr.c (make_message_rcslegal): Don't access uninitialized or
	unallocated memory; only strip trailing blank lines.
	* sanity.sh (log-3): Enhance to test this fix.

Fri Jan 16 12:41:03 1998  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* sanity.sh: Add keywordlog to list of tests run by default.

	* rcs.c (RCS_deltas): Don't call cvs_output if length is zero;
	passing zero length to cvs_output does not mean output zero
	bytes.  The 27 Dec 1997 change to no longer '\0'-terminate the
	->text field turned this from a time bomb to a user-visible bug.
	* sanity.sh (ann): New tests, test for this fix and other annotate
	behaviors.

Thu Jan 15 23:52:00 1998  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* root.c (root_allow_ok): If inetd.conf didn't specify an
	--allow-root options at all, we know we are in trouble.  Give a
	specific error message.

Thu Jan 15 21:24:59 1998  Ian Lance Taylor  <ian@cygnus.com>

	* sanity.sh (dotest_sort): New variant of dotest which sorts the
	output, for use when the output depends upon details of the file
	system, typically when doing an import.
	(rdiff): Use dotest_sort for rdiff-1.
	(ignore): Use dotest_sort for 188a, 188b, 189d, 190, and 191.

	* sanity.sh: (TESTSHELL): New variable.
	(editor, info, reserved): Use TESTSHELL in temporary script.

	* sanity.sh (ignore): Do all tests in subdirectory, to avoid
	conflict between cvsroot and CVSROOT on Windows.
	(binwrap3, mwrap, info, config): Likewise.

	* sanity.sh (binfiles2): Correct test name binfile2-7-brmod to
	binfiles2-7-brmod.

	* release.c (release_delete): If __CYGWIN32__ is defined, don't
 	worry about mismatched inodes.  This is a hack, but then I think
 	the test is rather peculiar anyhow.

Thu Jan 15 16:07:36 1998  Larry Jones  <larry.jones@sdrc.com>

	* sanity.sh (reserved-9): Use ${PROG} instead of "cvs".

Wed Jan 14 15:43:13 1998  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* Split ChangeLog into ChangeLog-97 and ChangeLog.
	* Makefile.in (DISTFILES): Add ChangeLog-97.

13 Jan 1998  Jim Kingdon

	* client.c: Declare handle_mt.

Tue Jan 13 22:21:30 1998  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* sanity.sh: Add comment about how pwd and /bin/pwd often differ
	in behavior (but are not guaranteed to).

Tue Jan 13 13:49:53 1998  Ian Lance Taylor  <ian@cygnus.com>

	* sanity.sh: When setting TMPPWD use just pwd, not /bin/pwd.

	* update.c (checkout_file): Don't pass set_time as true to
	Version_TS if the file is dead.
	* sanity.sh (modules): Add tests modules-155c6 through
 	modules-155c8 to test for above patch (without the above patch,
 	modules-155c8 will fail when remote).

Tue Jan 13 10:37:02 1998  Larry Jones  <larry.jones@sdrc.com>

	* client.c (send_modified): Change bufsize and newsize from int
	to size_t to avoid type clashes in call to read_and_gzip.

Tue Jan 13 10:33:02 1998  Larry Jones  <larry.jones@sdrc.com>

	* zlib.c (read_and_gzip): Set finish to 0; it was uninitialized.

Tue Jan 13 10:26:43 1998  Larry Jones  <larry.jones@sdrc.com>

	* add.c, rcs.c: Plug memory leaks.

Mon Jan 12 10:45:27 1998  Larry Jones  <larry.jones@sdrc.com>

	* server.c (mkdir_p): Don't try to create nameless directories
	(i.e., given "/foo//bar", don't try to create "/foo/",
	just "/foo" and "/foo//bar") since it isn't necessary and
	it fails on some systems in unexpected ways.

1998-01-11  enami tsugutomo  <enami@but-b.or.jp>

	* rcs.c (linevector_copy): Delete lines before overwriting them.

Sat Jan 10 11:05:40 1998  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* cvsrc.c, entries.c, login.c, logmsg.c, myndbm.c, patch.c,
	release.c, server.c: Check for errors from getline, CVS_FOPEN,
	fprintf, CVS_UNLINK and fclose.  Note that the new errors are
	nonfatal.  This is because of conservatism more than because
	it is always the best thing.
	* login.c (get_cvs_password): Close the file when done with it.
	* client.c (notified_a_file): If -1 return from getline, check
	feof rather than assuming errno is set.

Fri Jan  9 14:38:54 1998  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* server.c (expand_proc): Also output server_dir in
	"Module-expansion", not just in output_dir ("Created", &c).
	* sanity.sh (modules2): New tests modules2-9 through modules2-12
	test for this.

Thu Jan  8 12:56:55 1998  Yasutoshi Hiroe  <hiroe@rgk.ricoh.co.jp>

	* import.c (import): Don't strcat on uninitialized memory.  Fixes
	possible SIGSEGV with zero-length message.

Tue Jan  6 22:56:29 1998  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* sanity.sh (crerepos): Fix mistaken variable name which caused us
	not to clean up at the end of the test.

Mon Dec 22 01:40:57 1997  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* add.c (add): Also look for .cvswrappers files.
	* sanity.sh (binwrap3): New tests binwrap3-2*, binwrap3-sub2-add*
	test for this.

Tue Jan  6 11:50:38 1998  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* sanity.sh (crerepos): New tests crerepos-8 through crerepos-18
	test behaviors when mixing repositories.

Sun Jan  4 17:40:22 1998  Jim Kingdon  <kingdon@harvey.cyclic.com>

	* version.c: Change version number to 1.9.23.

	* Version 1.9.22.


For older changes see ChangeLog-97.
