test suite out of the box!
OK'ed by wiz@ during freeze.
0.30 release. Speed improvements, bug fixes, and improved
infrastructure.
Several internal data formats have changed with this release;
migration is straight-forward, but slightly more complicated
than usual:
-- The formats used to store some cached data in the
database have changed. To upgrade your databases, you
must run:
$ mtn -d mydb.mtn db migrate
$ mtn -d mydb.mtn db regenerate_rosters
-- The metadata stored in _MTN in each workspace has been
rearranged slightly. To upgrade your workspaces, you
must run
$ mtn migrate_workspace
in each workspace.
All of these operations are completely lossless, and 0.30
remains compatible with earlier versions with regards to
netsync.
Speed improvements:
- Algorithm used to find branch heads rewritten, to use vastly
less memory and cpu. This not only makes 'mtn heads'
faster, but also 'mtn commit', 'mtn update', and other
commands, which were spending most of their time in this
code.
- The format used in the database to store the roster cache
was rewritten. This makes initial pull approximately twice
as fast, and somewhat improves the speed of restricted log,
annotate, and so on.
- The xdelta algorithm was further optimized.
- A memory leak in Botan was fixed, which was causing
excessive memory and CPU time to be spent during 'mtn
checkout'.
- Monotone has fast-paths for doing character set conversion
when the system it is running on uses plain ASCII. These
fast-paths now know that "646" is another name used for
ASCII, and systems that use this name (like some BSDs) now
benefit from the fast-paths.
- Miscellaneous other improvements.
Workspace format changes:
- It is now possible to write down a multi-parent (merge)
workspace. However, monotone will still refuse to work with
such a workspace, and there is no way to create one. This
change merely sets up infrastructure for further changes.
- _MTN/revision no longer contains only the parent revision
id; if you depended on this in scripts, use 'mtn automate
get_base_revision_id' instead. Also, _MTN/work has been
removed.
UI changes:
- 'mtn status' now includes the branch name and parent
revision id in its output.
- The output of 'mtn annotate' and 'mtn annotate --brief' has
been switched. The more human-readable output is now the
default.
- 'mtn pluck' now gives an error message if the requested
operation would have no effect.
- On command line syntax errors, usage information is now
printed to stderr instead of stdout. (Output requested with
--help still goes to stdout.) This should make it easier to
find bugs in scripts.
Bug fixes:
- While changelog messages have always been defined to UTF-8,
we were not properly converting messages from the user's
locale. This has now been fixed.
- An off-by-one error that caused some operations to abort
with an error message about "cancel_size <
pending_writes_size" has been fixed.
- In 0.29, --help output was not localized. This has been
fixed.
- In 0.29, setting merger = "emacs" would not work unless
EDITOR was also set to "emacs" (and similar for vi). This
has been fixed.
- A rare invariant violation seen when performing certain
sequences of renames/adds in the workspace has been fixed.
- If a user failed to resolve the conflicts in a text file, we
would continue asking them to resolve conflicts in remaining
files, even though the merge could not succeed. We now exit
immediately on failure.
- Work around some g++ 3.3 brokenness.
Documentation changes:
- Imported *-merge documents into the manual (they still need
to be cleaned up to fit in better).
Changes to automate:
- Bug fix in 'attributes': this command is supposed to list
attributes that were removed from a file in the current
revision; instead, it was listing all attributes that had
ever been removed from that file. Now fixed.
- New command 'get_corresponding_path': given a revision A, a
path P, and a revision B, looks up the file with name P in
revision A, and states what path it had in revision B.
- New command 'get_content_changed': given a revision A and a
path P, gives the ancestor of A in which P was last
modified.
- New command 'get_option': Fetches variables from
_MTN/options (e.g., the current workspace's branch and
database).
- New command 'genkey': an automate-friendly way to generate a
new monotone key.
0.29 release. Code cleanups and bug fixes.
New features:
- The output of 'mtn status' has been changed significantly; the
output formerly used by 'mtn status --brief' has become the
default. For output similar to the old 'mtn status', see
'mtn automate get_revision'.
- It is now significantly easier to control what merger
monotone uses to resolve conflicts; for instance, to use
emacs to resolve conflicts, add:
merge = "emacs"
to your .monotonerc file. To override temporarily, you can
also use the environment variable MTN_MERGE, which takes the
same strings. Currently recognized strings are "kdiff3",
"xxdiff", "opendiff", "tortoisemerge", "emacs", "vim", and
"meld".
- Formerly, monotone's sync-over-ssh support required that an
absolute path be used, with a URL like:
ssh://venge.net/home/njs/my-db.mtn
The following syntaxes are now supported as well:
ssh://venge.net/~/my-db.mtn
ssh://venge.net/~njs/my-db.mtn
Bugs fixed:
- The bug where monotone would sometimes respond to a control-C
(or several other signals) by locking up and refusing to exit,
has been fixed.
- Monotone now properly respects SIGPIPE. In particular, this
means that 'mtn log | less' should now exit promptly when
'less' is exited.
- 'mtn log' now flushes its output after each message; this
makes 'mtn log <FILES>' significantly more usable.
- 'mtn log <FILES>' formerly listed irrelevant revisions (in
particular, any revision which contained a delete of any files
or directories, was always included). This has been fixed.
- If, during an update, two files both had conflicts, which,
when resolved, resulting the two files becoming identical, the
update would error out. This has been fixed.
- If _MTN/log exists and does not end in a newline, we now add a
newline before using the log message. This removes a problem
where the string "MTN:" would end up appended to the last line
of the log message.
- We no longer buffer up an arbitrarily large number of pending
writes in the database. This improves speed and memory usage
for 'commit', and fixes the problem where 'cvs_import' would
run out of memory.
- Monotone's tree walking code (used by 'ls unknown', 'ls
missing', and friends) now uses much less memory, especially
on reiserfs.
Automate changes:
- 'mtn automate stdio' now uses a configurable block size,
controlled by command-line option --automate-stdio-size. This
is mostly useful for testing speed/memory trade-offs.
- 'automate attributes' has a new format, which includes more
information.
Code cleanup:
- We now use boost::program_options to parse command line
options, rather than popt. The only user-visible change
should be that --option="" no longer works as a way to set
some option to the empty string; use --option "". (This
change also removes a lot of orphaned and historically buggy
code from monotone.)
Other:
- zsh completion script significantly revised and updated (see
contrib/monotone.zsh_completion).
0.28 release. Cherrypicking, a new testsuite, and some fixes
and enhancements.
New features:
- Cherrypicking with the new "pluck" command. This takes (a restricted
subset of) the changes in a revision, or between two
revisions, and applies them to your workspace. That this
has happened is not recorded in history; it as if you
happened to make some very similar changes by hand in your
workspace.
- New automate commands, "automate tags" and "automate branches".
- "diff" now knows how to find enclosing function (or
whatever) bodies, just like GNU diff's "-p" option.
-- The regex that defines "enclosing function" can be chosen
on a per-file basis by a hook function; the default hook
knows about LaTeX, Texinfo, and most programming
languages.
-- This is enabled by default; use --no-show-encloser to
disable.
Enhancements:
- When netsync fails due to permission errors, the server returns a
semi-intelligible message before dropping the connection.
- When merging a branch with 3 or more heads, the order in which to
merge the heads will now automatically be chosen to minimize
the amount of repeated work that must be done.
- Crash dumps are now written to $CONFDIR/dump when no workspace is
available
- Path validation routines are faster.
- Inodeprints should be slightly more robust now.
- New hook get_mtn_command, used to determine the path to the
mtn binary on a remote host, when using ssh support.
- "diff" now accepts "-u" and "-c" as short for "--unified"
(the default) and "--context", respectively.
Bug fixes:
- "revert --missing" now works when run in a subdirectory.
- "revert --missing" now works without any additional files
being specified. (You don't have to say "mtn revert
--missing .".)
- Fix an edge case where monotone would crash if there was a
content conflict in a merge for which there was no lca.
- Fix a case where netsync would sometimes hang during refinement.
- "mtn help" and "mtn --help" now exit with return code 0.
Build environment:
- automake 1.9 is now required.
- The testsuite has been rewritten, and should be much faster now. It
also no longer relies on the presence of a *nix userland.
- Add workaround for gcc 4.1.[01] bug causing "multiple
definition" errors.
Internal:
- Restrictions have been split into path_restrictions and
node_restrictions, and generally cleaned up more.
0.27 release. Minor bug fixes and enhancements, plus ssh
support.
Major new features:
- Monotone can now push/pull/synchronize over arbitrary
bidirectional streams, not just raw TCP.
- File-to-file synchronization is enabled out of the box,
e.g.:
$ mtn -d db1.mtn sync file:/path/to/db2.mtn
- SSH synchronization is enabled out of the box, e.g.:
$ mtn -d local.mtn sync ssh://njs@venge.net/home/njs/remote.mtn
Note that this requires mtn be installed on the remote
computer, and locks the remote database while running; it
is not ideal for groups accessing a shared database.
- New protocols can be defined with Lua hooks -- for
example, someone could in principle make "$ mtn sync
xmpp://njs@jabber.org" do something interesting.
- See section "Other Transports" under "Advanced Uses" in the
for more details.
Minor new features:
- Selectors now support escaping, e.g., b:foo\/bar can be used
to refer to a branch with name "foo/bar" (normally / is a
metacharacter that separates multiple selectors).
- Visual C++ can now build monotone on Windows. (Mostly
important because it allows better Windows debugging.)
- --quiet now turns tickers off, and does not turn warnings
off. New option --reallyquiet disables warnings as well.
- New command 'automate common_ancestors'.
- 'ls branches' now takes a pattern, e.g.:
$ mtn ls branches "*contrib*"
Speed improvements:
- Bug in select() loop fixed, server should no longer pause in
processing other clients while busy with one, but multiplex
fairly.
- The database has a new write buffer which gives significant
speed improvements in initial pulls by cancelling redundant
database writes.
- There's been a fair bit of performance tuning all around.
Bug fixes:
- Merge tools that exit in failure are now detected.
- Better reporting of operating system errors on Win32.
- Passphrases stored in ~/.monotonerc are no longer written to
the log file. (Passphrases entered at the terminal were
never written to the log file.)
- Fix sql injection bugs in selectors, making it safe to
expose slectors in web interfaces etc.
- Files marked with the mtn:execute attr now respect umask.
- 'automate' commands on Win32 now disable newline translation
on their output; this is especially important for 'automate
stdio'.
- 'db check' now calls the sqlite "PRAGMA integrity_check", to
validate the integrity of things like sqlite indices.
- 'mtn annotate nonexistent-file' now gives a proper error
message, instead of an assertion error.
- 'mtn revert --missing' now works correctly when run in a
subdirectory.
- 'automate inventory' no longer fails when _MTN/work contains
patch stanzas.
Other:
- Many, many internal code cleanups
- Including changes to somewhat reduce the size of the
binary
- New tutorial on using packets added to the manual
- Updated translations, improved error messages, etc.
Reliability considerations:
- In the two months since 0.26 was released, zero serious bugs
have been reported in the new code.
PKGLOCALEDIR and which install their locale files directly under
${PREFIX}/${PKGLOCALEDIR} and sort the PLIST file entries. From now
on, pkgsrc/mk/plist/plist-locale.awk will automatically handle
transforming the PLIST to refer to the correct locale directory.

0.26 release. Major enhancements and internal rewrites.
Please read these notes carefully, as significant changes are
described. In particular, you _cannot_ upgrade to 0.26
without some attention to the migration, especially if you are
working on a project with other people. See UPGRADE for
details of this procedure.
The changes are large enough that there were 3 pre-releases of
this code; the changes that occurred in each can be seen
below. However, for the convenience of those following
releases, all changes since 0.25 will be summarized in these
release notes. There is no need to read the pre-release notes
individually.
Major changes since 0.25:
- The most user-visible change is that the default name of the
monotone binary has changed to 'mtn'. So, for example, you
would now run 'mtn checkout', 'mtn diff', 'mtn commit',
etc., instead of 'monotone checkout', 'monotone diff',
'monotone commit'.
- Similarly, the name of the workspace bookkeeping directory
has changed from "MT" to "_MTN". As workspaces will
generally be recreated when migrating to this release,
this should not cause any problems.
- Similarly, built-in attrs like 'execute' have had 'mtn:'
prepended to their names. For example, executable files
should now have the attr 'mtn:execute' set to 'true' on
them. The migration code will automatically add this
prefix; no user intervention is needed.
- Similarly, the name of the ignore file has changed from
'.mt-ignore' to '.mtn-ignore'. The migration code will
automatically rename this file; no user intervention is
needed.
- Similarly, the recommended suffix for monotone db files is
now '.mtn'.
These changes are all purely cosmetic, and have no affect on
functionality.
- The most developer-visible change is that the data
structure for representing trees has been completely
replaced, and all related code rewritten. The new data
structure is called a 'roster'. You don't really need to
know this name; unless you are hacking on monotone or using
various debug operations, you will never see a roster.
It's mostly useful to know that when someone says something
about 'roster-enabled monotone' or the like, they're
referring to this body of new code.
This change has a number of consequences:
- The textual format for revisions and manifests changed.
There is no conceptual change, they still contain the same
information and work the same way. The formats were
merely cleaned up to correct various problems experience
showed us, and allow various enhancements now and in the
future. However, this change means that a flag-day
migration is required. See UPGRADE for details.
- Directories are now first-class objects. You can add an
empty directory, must drop a directory if you want it to
go away, etc.
- Attrs are now first-class objects. '.mt-attrs' no longer
exists; attrs are now described directly in the manifest,
and changes to them appear directly in revisions. The
migration code will automatically convert existing
.mt-attrs files to the new first-class attrs. If you have
custom attrs, those may require special handling -- if
this is the case, then the upgrader will tell you.
- The merge code has been rewritten completely. The
interface is currently the same (though this rewrite makes
it easier to improve the interface going forward); if you
have found merging in monotone to be easy in the past,
then you will not notice anything different. If you have
run into problems, then the new merger should make your
life substantially simpler. It has full support for
renames (of both directories and files), intelligent
merging of attrs, improved handling of file content
merges. Is the first known merger implementation based on
a provably correct algorithm (the "multi-*-merge"
algorithm), has exhaustive automated tests, and generally
should give accurate, conservative merges.
- The new code is generally faster, though not yet as
fast as it could be.
Netsync changes:
- The default netsync port has changed 5253 to 4691. 4691 is
our official IANA-assigned port. Please adjust firewalls
appropriately.
- Netsync code has also been largely reworked; new code should
provide better opportunities for
- The protocol is incompatible with earlier versions of
monotone. This should not be a surprise, since the data it
carries is also incompatible (see above)...
New features:
- New option --brief to 'annotate', gives somewhat more
friendly output.
- Several enhancements to log:
- New option --next, to display descendent revisions
(rather than ancestor revisions).
- When 'log -r' is given an ambiguous selector, it now just
logs all matching revisions, instead of requiring the
selector be disambiguated.
- New option --no-files.
- New command 'show_conflicts', performs a dry run merge.
- New command 'ls changed'.
- 'rename' (and its alias 'mv') now accept a broader range of
syntax:
mtn rename foo some_dir
-> renames foo to some_dir/foo
mtn rename foo bar baz some_dir
-> moves foo, bar, and baz to some_dir/foo,
some_dir/bar, and some_dir/baz
- New hook 'validate_commit_message', which may be used to
verify that all commit messages meet arbitrary user-defined
rules.
- New option --log, to log monotone's output to a file.
- New option 'drop --recursive', to remove a directory and its
contents in one swoop.
- The root dir may now be renamed. This is a somewhat exotic
feature, but has some interesting uses related to splitting
up or joining together projects; see new commands
'pivot_root', 'merge_into_dir'.
Minor bug fixes:
- 'serve' with no --bind argument should now work on systems
where the C library has IPv6 support, but the kernel does
not.
- Stricter checking on the internal version of filenames to
ensure that they are valid UTF-8.
- If the database is in the workspace, then it is always
ignored.
- Monotone no longer errors out when using a French (fr)
locale with a non-Unicode codeset.
Other changes:
- Packet commands ('rdata', 'fdata', etc.) have been moved to
'automate'.
- Database storage now uses sqlite's blob support; database
files should be ~1/4 smaller as a result.
- Monotone now uses sqlite 3.3; this means that older versions
of the command line client (e.g., an 'sqlite3' command built
against sqlite version 3.2) cannot be used to poke at a
monotone 0.26 database. Solution is to upgrade your sqlite3
program. Hopefully this is irrelevant to most users...
- Translations updated, and 3 new translations added (de, it,
sv).
Reliability considerations:
- This new codebase has received much less testing under real
world conditions than the codebase used in 0.25, simply
because it is newer. It has been in active use for monotone
development since 8 January 2006, and only a small number of
bugs have been found; all bugs found so far have been very
minor, and none stood any danger of corrupting data.
Furthermore, we are much more confident in the theoretical
underpinnings of the new approach than the old, and the test
suite attempts to exhaustively exercise all new code paths.
However, none of this is or can be a substitute for real
world experience. We advise caution in upgrading to this
version of monotone, and suggest that (especially) those who
upgrade aggressively should pay extra attention to the
monotone mailing list before and after doing so.

0.26pre3 release. This release may be considered a "release
candidate", in that while we need to write some tests and make
sure some bugs are fixed, all features are in and we hope that
no further bug fixes will be needed either. It is still a
pre-release for testing. Do not package it. DO NOT USE THIS
RELEASE UNLESS YOU WANT TO BE A DAREDEVIL.
But, PLEASE PLEASE TEST this release. There are some
non-trivial changes since 0.26pre2, and this is your last
chance!
Major changes since 0.26pre2:
- The name of the monotone binary has changed to 'mtn'.
- Similarly, the name of the bookkeeping directory in
workspaces has changed from 'MT' to '_MTN' (if you have an
existing 0.26-line workspace, just rename the MT directory
to _MTN).
- Similarly, the name of the ignore file has changed from
".mt-ignore" to ".mtn-ignore". 'rosterify' will rename
these automatically (if you have already rosterified, you
get to rename them by hand).
- Similarly, the recommended suffix for monotone db files is
now ".mtn".
- We now perform stricter checking to make sure that filenames
are valid UTF-8. It is in principle possible that this
stricter checking will cause histories that used to work to
break; if you have non-ascii filenames, it is strongly
recommended to test with this release.
- Root dir renaming is now supported. See new commands
'pivot_root', 'merge_into_dir'.
- As a side-effect, it is now possible to run 'rosterify' on
histories in which two independent lines of history were
merged.
- The security fix released in 0.25.2 has been forward-ported
to this release; this prevents some security exposure to
people running monotone as a client on case-insensitive file
systems.
Minor change since 0.26pre2:
- Database now uses sqlite blobs for storage; should be ~1/4
smaller.
- New command: show_conflicts, does a dry-run merge.
- New option 'drop --recursive', to remove a directory and all
its contents in one swoop.
- Changes to 'log':
- New option --no-files
- Including merges is again the default (i.e., it now acts
like 0.25, and not like 0.26pre2).
- When 'log -r' is given an ambiguous selector, it now just
logs all matching revisions, instead of requiring the
selector be disambiguated.
- New option --log, to log monotone output to a file.
- Netsync changes:
- Was sending far too much data in some cases; now does not.
- Several bugs that caused it to lock up fixed
- Tweak to allow 'usher' proxy to transparently redirect
based on client's protocol version, to ease migration
between incompatible protocol versions.
- Packet commands have been moved to 'automate'.
- Fixed bugs in 'db kill_rev_locally', should no longer leave
an inconsistent db behind.
- Translation updates
Other projects receiving notable work:
- Monotone's "dumb server" support (repo distribution over
HTTP/FTP/SFTP etc.) has been ported to 0.26, a first command
line version written, etc.
- The 'usher' netsync proxy used for hosting many databases on
a single machine has received significant cleanups, and the
'webhost' project to provide a simple interface to shared
monotone hosting providers has received even more work.
Sat Feb 11 13:32:51 PST 2006
0.26pre2 release. Inching towards 0.26. If you are using
0.25 or earlier, then make sure to read the very important
notes for 0.26pre1, below. In particular, like 0.26pre1, this
is a pre-release for testing. Do not package it. DO NOT USE
THIS RELEASE UNLESS YOU WANT TO BE A DAREDEVIL.
(Though, in fact, in a month of usage, only one bug has been
found in the new history code, and it was both minor and
harmless. It has additionally been fixed.)
Database changes:
- SQLite 3.3.3 has been imported. 3.3 introduces a new database
format that is not backwards compatible with earlier 3.x releases.
New databases will be created using this new format. Existing
databases remain compatible, and are not converted automatically.
Existing databases can be converted by performing a database
vacuum ('monotone db execute vacuum').
New features:
- New hook validate_commit_message -- use to verify that all
commit messages meet arbitrary user-defined rules.
UI improvements:
- rename (and mv) commands now accept a broader range of
syntax:
monotone rename foo some_dir
-> renames foo to some_dir/foo
monotone rename foo bar baz some_dir
-> moves foo, bar, and baz to some_dir/foo,
some_dir/bar, and some_dir/baz
- Print a warning if it looks like a user has made a quoting
mistake on push/pull/sync/serve (windows cmd.exe has
confusing rules here).
- New command "ls changed".
- New option "--next" to log, which displays descendents of
the start revision.
- Updating to an arbitrary revision now works again (as it did
in 0.25 and earlier). This allows one to, for instance,
switch a working copy to another head, or back up to an
earlier version, while preserving uncommitted changes.
- New option --brief to annotate, gives somewhat more friendly
output.
- Fixed bug that made ticker output from netsync inaccurate.
- In 'log', --no-merges is now the default, use --merges to
override.
- If the database is in the working copy, then it is always
ignored.
Bugs:
- 'serve' with no --bind should now work on systems where the
C library has IPv6 support, but the kernel does not.
- Compile fixes for GCC 4.1 pre-releases.
Other:
- Better detection when users have not run "rosterify", and
more helpful suggestions on what to do in this case.
- Documentation, translation, error message,
etc. improvements.
- Updates to contrib/mtbrowse.sh, simple shell-based monotone
interface.
- Updates to many other contrib/ files, mostly to maintain
compatibility with monotone changes.

0.26pre1 release. Massive rewrites, released for shakedown.
This release is also dedicated to Shweta Narayan.
This release includes massive changes compared to 0.25. The
core versioning code has all been replaced with a completely
different mechanism. Data formats and the netsync protocol
have changed in incompatible ways.
Migration to 0.26pre1 or later is irreversible and requires a
flag day for your project. See UPGRADE for details. Note
that we DO NOT recommend upgrading at this time; see below.
If you have been following the development list for the last
few months, you may have heard about "rosters" -- this is the
name for the new core data structure we use. While the code
is completely different, the user experience should not be
very different. You will never see a roster, unless you are
debugging monotone itself; everything still revolves around
revisions, manifests, and certs.
While this new code has extensive tests, because of these
incompatibilities, it has never been used for real work. The
purpose of this release is to make a version available for the
monotone developers to begin using for day-to-day work, to
shake out bugs.
Let's say that again in caps: THIS CODE IS PROBABLY BUGGY, DO
NOT USE IT IN PRODUCTION UNLESS YOU WANT TO BE A DAREDEVIL.
However, testing of this version with real databases is a good
idea, and we'd very much appreciate hearing about your
experiences.
Some of the many changes:
- New textual format for revisions and manifests; they remain
conceptually the same, but have been tweaked. Manifests
now use the same "basic_io" format as everything else in
monotone, and contain entries for directories, revisions
record file adds slightly differently and record directory
adds for the first time, etc. Because of this format
change, revision hashes are now different; converting
rosters requires a full history rebuild and reissue of certs.
- Directories are now first class. To get rid of a directory
you must remove it; to create a directory, you must add it.
You can add an empty directory.
- Attrs are now first class. The .mt-attrs file is gone;
attributes are now stored directly in the manifest.
- New merge algorithm, based on "multi-*-merge", and more
aggressive, less buggy merge ancestor selection code
- Netsync's core has been largely rewritten. Code is now much
clearer and more reliable, and now includes the ability to
resume interrupted partial transfers. The netsync protocol
version number has been bumped, and netsync now runs on the
IANA-assigned port 4691 by default.
- 100% fewer change_set.cc related bugs. 100% more roster.cc
related bugs. But the idea of touching roster.cc does not
terrify people.
0.25.2 release. Important security fix for Windows and OS X
users.
With versions of monotone prior to this release, a person with
commit access could commit a malicious file with a name like
"mt/monotonerc". When anybody else then checked out this
revision on a system with a case-folding filesystem --
usually, this means, "on Windows or OS X" -- then their
monotone would run arbitrary Lua code stored in this file.
The _only_ change in this release as compared to 0.25 is that
the existing checks against files in MT are now extended to
check for mt, Mt, and mT.
All users on Windows and OS X, or otherwise checking out
versioned source on a case-insensitive filesystem, are
recommended to upgrade immediately. Binaries used only for
serving, or only on case-insensitive filesystems (i.e., most
Unix users), are not affected.
(0.25.1 was never released in source form. The original
0.25 build for Windows was found to have problems on NT 4, and
0.25.1 was Windows-only rebuild with NT 4 compatible
libraries.)
makeinfo if no native makeinfo executable exists. Honor TEXINFO_REQD
when determining whether the native makeinfo can be used.
* Remove USE_MAKEINFO and replace it with USE_TOOLS+=makeinfo.
* Get rid of all the "split" argument deduction for makeinfo since
the PLIST module already handles varying numbers of split info files
correctly.
NOTE: Platforms that have "makeinfo" in the base system should check
that the makeinfo entries of pkgsrc/mk/tools.${OPSYS}.mk are
correct.
Incompatible command line changes:
- 'monotone revert' now requires an argument. To revert your
entire working copy,
$ monotone revert
no longer works; instead, go to the root of your working
copy and run
$ monotone revert .
New features:
- Netsync now supports IPv6 (where OS support exists)
Bugs fixed:
- 'revert' gives feedback describing what it changes
- Database locking further tweaked, to allow more concurrent
access in situations where this is safe.
- On win32, ticker display was fixed, so that it no longer
prints a new line at each update.
- 'read' can now understand (and migrate) privkey packets
generated by monotone version 0.23 or earlier.
- 'log --diffs <files>' now prints only diffs for the given
files (previously, it would print only revisions in which
the given files changed, but would print all diffs for those
revisions).
- Win9x and WinNT 4 compatibility fixes.
New translations:
- pt_BR
Major key management changes:
- Private keys are no longer stored in your database. They
are stored in ~/.monotone/keys/ (Unix, OS X) or
%APPDATA%\monotone\keys\ (Windows). 'db migrate' will
automatically move your keys out of your database and into
their proper location. Consequences:
- 'genkey' no longer requires a database. Simply run it
once when you first start using monotone, even before you
have created a database.
- Running 'genkey' once will suffice to give all databases
on one computer access to your key. No more fiddling with
'read'.
- When you want to make your key available on another
computer, simply copy over the appropriate file from your
'keys' directory to the corresponding directory on the new
computer.
- Private keys also use a more standard on-disk envelope
encoding ("PBE-PKCS5v20(SHA-1,TripleDES/CBC)") instead of
previous ARC4. More secure, and with extra crypto karma.
Netsync changes:
- Command line syntax for 'serve' changed; administrators WILL
have to adjust scripts.
monotone serve my.host.com "*"
becomes
monotone serve --bind=my.host.com "*"
or simply
monotone serve "*"
(to serve on the default port, on all interfaces).
- Speaking of which, we can now bind to all interfaces; run
'serve' without passing --bind, or with passing
--bind=:port, and monotone will listen on all interfaces.
- New option '--key-to-push' for 'push', 'sync', allows
administrator to push a new user's public key into a running
server without restarting it.
- Netsync permission hooks have new defaults that read a
description of allowed access out of a standard,
basic_io-based textfile (the same stanza-based format that
revisions use). Current hooks will continue to work, but
users may prefer to transition to this format; see manual
for details.
- Between these, it is now straightforward to change
permissions and add users without restarting your server.
- Improvements to experimental "usher" facility.
UI improvements:
- New convenience options "add --unknown", "drop --missing",
"revert --missing" do what you'd expect -- add all
non-ignored non-versioned files, drop all
deleted-but-undropped files, and restore all
deleted-but-undropped files, respectively.
- New selector "h:" to select heads of a branch. "h:" means
heads of current branch, "h:mybranch" means heads of
mybranch.
- Similarly, "b:" selector with no argument now refers to
current branch.
- Commit messages now have a blank line at the top so you can
start typing directly.
- No more obscure error messages when multiple monotone
processes attempt to access a single database at the same
time; we now fail early with a more sensible error message.
(Concurrent access has never caused database corruption;
this simply makes the corruption prevention less frustrating
for the user.)
- New handlers for SIGTERM, SIGINT to rollback database
transactions. Not visible to users (unless you're really
looking carefully). (Again, killing monotone has never been
able to cause database corruption; this simply causes the
transactions to be rolled back immediately, rather than the
next time monotone runs, which improves robustness in some
theoretical way.)
Changes in 'automate':
- New command 'automate keys' to get information on existing
keys in basic_io format.
Updated translations:
- fr
Smaller changes:
- Improved handling of multibyte characters in message
displays.
- Fixes to Botan's memory allocator, to avoid pathological
slowdowns in some rare cases.
- Fix bug in delta-storage code; we were not being as aggressive
about delta-compressing files and manifests as we should
have been.
- Minor bugs fixed, error messages improved.
- Upgrading from 0.23: You must run 'db migrate' and
provide your password, for each database.
Possibly incompatible changes:
- hook_note_commit and hook_note_netsync_revision_received
take a new argument containing the text of the revision that
was received. (Timothy Brownawell <tbrownaw@gmail.com>)
- 'cat FILENAME' now acts like the old 'cat file REV
FILENAME'; use new commands 'automate get_revision',
'automate get_manifest', 'automate get_file' to fetch
objects by hash. (Grahame Bowland <grahame@angrygoats.net>)
General improvements:
- .mt-ignore support (Martin Dvorak
<jezek2@advel.cz>, Timothy Brownawell <tbrownaw@gmail.com>)
- much work on making monotone more i18n friendly (Benoît
Dejean <benoit@placenet.org>, Matt Johnston
<matt@ucc.asn.au>)
- support for more interactive merge tools:
- FileMerge.app (comes with OS X) (Marcel van der Boom
<marcel@hsdev.com>)
- TortoiseMerge (Win32; comes with TortoiseSVN) (Matthew
Gregan <kinetik@orcon.net.nz>)
- rename and drop now actually perform the specified rename or
deletion when the argument --execute is passed. (Richard
Levitte <richard@levitte.org>)
- 'help' command, same as --help (Matt Johnston
<matt@ucc.asn.au>).
- 'usher' support: experimental method for proxying multiple
netsync servers through a single port (similar concept to
vhosts) (Timothy Brownawell <tbrownaw@gmail.com>)
- support long passphrases (Matt Johnston <matt@ucc.asn.au>)
- Faster binary file detection (Eric Anderson
<anderse-monotone@cello.hpl.hp.com>)
- netsync speedups:
- when handling large files (Eric Anderson
<anderse-monotone@cello.hpl.hp.com>)
- when handling many branches (Marcel van der Boom
<marcel@hsdev.com>)
- new system to allow crash logs to contain not just execution
traces, but also dumps of data being handled when the error
was detected -- greatly improves debuggability of user
crashes.
- complete rework of path handling code, for clarity,
robustness, and speed. No user visible changes, except for
the many bugs fixed. (Special thanks to Matthew Gregan
<kinetik@orcon.net.nz> and Grahame Bowland
<grahame@angrygoats.net>.)
- however, if you have non-normalized paths in your history
(symptom: fresh pulls with 0.18 work, but fresh pulls with
0.19 do not), then 0.23 will report an error and refuse to
handle the affected revisions. Since it is believed this
only affects one project, and to conserve core developer
time, implementing a migration was put off for now. If
this causes problems or for more details, please send an
email to monotone-devel@nongnu.org.
- as always, many small bug fixes, speedups, and improved
messages.

Other new monotone-related projects since 0.22:
- mtsh by Timothy Brownawell:
https://netfiles.uiuc.edu/brownawe/www/mtsh/
GTK+ wrapper for monotone focusing on working copy
operations -- add/drop/revert/rename/commit/update/diff and
browsing. Has a mechanism for per-file commit comments.
- "dumb server" support by Nathaniel Smith (share your
monotone repositories via HTTP/FTP, no netsync daemon
needed):
http://viewmtn.angrygoats.net//branch.psp?branch=net.venge.monotone.dumb
Still needs a command-line frontend to be usable, among
other things. Help wanted. In python.
- m7 by Larry Hastings <larry@hastings.org>
http://www.midwinter.com/~lch/programming/m7/
Experimental drop-in command-line wrapper for monotone.
Uses certs to add local incrementing version numbers, and an
enhanced annotate front-end.
Mon Aug 8 23:23:53 PDT 2005
0.22 release. new crypto library, bug fixes, ui improvements
- switch from crypto++ to botan as underlying crypto library.
this should not cause any user-visible changes; let us know
if it does. special thanks to Matt Johnston
<matt@ucc.asn.au>, Kaushik Veeraraghavan
<kaushikv@gmail.com>, Matthew Gregan
<kinetik@orcon.net.nz>.
- incompatible change to netsync permission hooks: the
get_netsync_anonymous_read_permitted hook has been removed;
instead, get_netsync_read_permitted will be called with a
key name of nil. server administrators should update/review
their configuration
- new option for merge and propagate: --lca. Until we get a
long-term solution to the various 3-way merge problems, this
should be more convenient than using explicit_merge.
- many small improvements to error messages, fixes of minor
annoyances, netsync tickers more accurate, etc.
Sun Jul 17 16:48:26 PDT 2005
0.21 release. bug fixes, performance improvements, and ui
improvements.
- fixes a number of major performance bugs in 0.20's netsync
implementation. special thanks to Matt Johnston
<matt@ucc.asn.au>.
- fixes a number of major bugs in 0.20's (rewritten)
cvs_import command.
- configury kluges to work around g++ 4.0/boost 1.32
incompatibilities. special thanks to Christof Petig
<christof@petig-baender.de>, Matthew Gregan
<kinetik@orcon.net.nz>, Jordan Breeding
<jordan.breeding@mac.com>.
- ui enhancements:
- new netsync option "--exclude": branches are included if
they match any of the given globs, unless they match any
of the given --exclude globs. special thanks to Timothy
Brownawell <tbrownaw@gmail.com>.
- new netsync option client "--set-default": makes it easy
to change default server/branches.
- "diff" now takes options "--context" and "--external", to
output context diffs and to invoke an external diff
program for full control over output formatting. new
option "--diff-args" pass arguments to external diff
program; new hook "external_diff" allows further
configuration. special thanks to Vladimir Vukicevic
<vladimirv@gmail.com>.
- b: and t: selectors now match exactly, instead of matching
as substrings. globbing is supported for inexact
matching. special thanks to Brian Downing
<bdowning@lavos.net>, Jordan Breeding
<jordan.breeding@mac.com>.
- new command 'db kill_tag_locally'. special thanks to Jordan
Breeding <jordan.breeding@mac.com>.
- now uses sqlite3 prepared statements. special thanks to
Derek Scherger <derek@echologic.com>.
- 'db migrate' is now a complete no-op if there is no
migration to do; automated scripts can now call it
optimistically and cheaply to guarantee up-to-dateness.
- new hash correctness tests. special thanks to Kaushik
Veeraraghavan <kaushikv@gmail.com>.
- upgrading from 0.20: you must run 'monotone db
migrate' once against each of your databases, to add
new sql indexes.
Tue Jul 5 23:57:10 PDT 2005
0.20 release. features, ui improvements, performance
improvements, and bug fixes.
- major changes in netsync UI: serve/sync/push/pull now take a
list of globs; clients can request arbitrary sets of
branches, not just predefined "collections". write
permissions are now granted on a per-db level (they were
before anyway).
- where you used to say, e.g., "monotone pull
net.venge.monotone", you should instead say
"monotone pull net.venge.monotone*". This may
require shell-quoting.
- 'get_netsync_write_permitted' hooks must be changed
to take only one argument, the 'identity'.
'get_netsync_{read,anonymous_read}_permitted' hooks
now take a branch argument instead of a collection,
and will be called for each branch that a client
requests.
- 0.19 clients cannot talk to 0.20 servers, and vice-versa.
- special thanks to Timothy Brownawell
<tbrownaw@gmail.com>, Richard Levitte
<richard@levitte.org>.
- other major changes:
- cvs_import re-written; many bugs fixed. now
supports tags.
- many minor netsync changes:
- netsync traffic is now cryptographically authenticated
against corruption and man-in-the-middle attacks.
special thanks to Ethan Blanton <elb@elitists.net>,
Matt Johnston <matt@ucc.asn.au>.
- new hooks that are called when server receives data:
note_netsync_*_received. special thanks to Timothy
Brownawell <tbrownaw@gmail.com>.
- ancestry graphs that pass outside the given branch
are now synchronized correctly. special thanks to
Timothy Brownawell <tbrownaw@gmail.com>.
- UI improvements:
- 'log' options changed: --depth has become --last;
new options --no-merges, --diffs, --brief.
- 'status' has new option --brief. special thanks to
Derek Scherger <derek@echologic.com>.
- 'serve' has new option --pid-file. special thanks
to Matthew Gregan <kinetik@orcon.net.nz>.
- all commands taking restrictions now take option
--depth, to limit recursion through subdirectories.
special thanks to Joel Reed <joelwreed@comcast.com>.
- merge command all take --author, --date now.
- 'checkout', 'update' take --revision, instead of
using positional arguments. special thanks to Derek
Scherger <derek@echologic.com>, Richard Levitte
<richard@levitte.org>.
- 'commit' takes new --message-file option.
- new features:
- new commands: "db kill_branch_locally", "db
kill_revision_locally", useful for correcting some
mistakes. special thanks to Brian Campbell
<brian.p.campbell@dartmouth.edu>, Sebastian Spaeth
<Sebastian@sspaeth.de>.
- new file attribute 'manual_merge', to prevent invocation of
merger on binary files. hook added to guess correct
value at 'add' time. special thanks to Riccardo
Ghetta <birrachiara@tin.it>.
- new 'earlier than', 'later than' selectors. special
thanks to Riccardo Ghetta <birrachiara@tin.it>.
- new automate commands:
- 'stdio', for efficient use by
front-ends. special thanks to Timothy Brownawell
<tbrownaw@gmail.com>.
- 'certs', for fetching certs on a revision in a
parseable (basic io-based) format. special thanks
to Grahame Bowland <grahame@angrygoats.net>.
- 'inventory' output changed incompatibly; should be
much more usable now, and stable. special thanks to
Derek Scherger <derek@echologic.com>.
- better memory/performance when handling large files.
special thanks to Eric Anderson
<anderse-monotone@cello.hpl.hp.com>, Timothy Brownawell
<tbrownaw@gmail.com>, Matt Johnston <matt@ucc.asn.au>,
Matthew Gregan <kinetik@orcon.net.nz>.
- new text mode browser in contrib/mtbrowse.sh, by Henry
Nestler <Henry@BigFoot.de>.
- improved zsh completion in contrib/monotone.zsh_completion,
by Joel Reed <joelwreed@comcast.com>.
- upgrading from 0.19: database and working copies are
fully compatible. netsync clients and servers need
to be upgraded together, as described above. the
many ui changes may require script updates.
0.19 release. performance improvements, features, ui
improvements, and bug fixes.
- many operations sped up by another factor of 2 or better.
- special thanks to Matt Johnston <matt@ucc.asn.au>.
- first steps towards automated benchmarking. Thanks
to Timothy Brownawell <tbrownaw@gmail.com>.

Thanks to Emile Snyder <emile@alumni.reed.edu>.
- "inodeprints" for fast change detection in large
working dirs now fully supported; see manual for
details.
- new minor features:
- new selector "c:name=value" for selecting on
arbitrary certs. Thanks to Richard Levitte
<richard@levitte.org>.
- new hooks to automatically initialize attributes on
add; monotone now automatically sets execute bit on
executables. Thanks to Joel Reed
<joelwreed@comcast.net>.
- new automate command "select", to do selector
expansion. Thanks to Richard Levitte
<richard@levitte.org>.
- new automate commands "graph", "parents",
"children", "ancestors", to easily inspect history.
Special thanks to Sebastian Spaeth
<Sebastian@SSpaeth.de>.
- new command "db kill_rev_locally". Thanks to
Sebastian Spaeth <Sebastian@sspaeth.de>.
- new arguments to "commit": --author, --date; useful
for patch attribution and importing history.
- new automate command "inventory" (output format will
change in next release, however). Thanks to Derek
Scherger <derek@echologic.com>.
- ui improvements:
- netsync progress ticker in kilobytes/megabytes.
Thanks to Matt Johnston <matt@ucc.asn.au> and
Sebastian Spaeth <Sebastian@sspaeth.de>.
- tickers do not cause annoying scrolling when wider
than window. Special thanks to Matthew Gregan
<kinetik@orcon.net.nz>.
- warn users when a commit creates divergence, and
when an update ignores it. Thanks to Jeremy Cowgar
<jeremy@cowgar.com>.
- support for command-specific options (there is still
no rule that such options must appear after the
command on the command line, though). Thanks to
Richard Levitte <richard@levitte.org>.

in scripts. Thanks to Derek Scherger
<derek@echologic.com>.
- many others...
- fantastic emacs integration in contrib/monotone.el. Thanks
to Harley Gorrell <harley@panix.com>.
- 45 new integration tests. total line coverage: ~84%.
- upgrading from 0.18: database and working copies are
fully compatible. NOTE that the configuration file
is now ~/.monotone/monotonerc, rather than old
~/.monotonerc. Simply create ~/.monotone, and
rename any existing configuration file.
0.18 release. performance improvements, features, and bug fixes.
This release is dedicated to Shweta Narayan.
- most operations sped up by a factor of 2 or better; many sped up
by up several orders of magnitude.
- special thanks to Matt Johnston <matt@ucc.asn.au>, Derek
Scherger <derek@echologic.com>, Linus Torvalds
<torvalds@osdl.org>.
- new concept: "database vars". Used in several features below.
- new features:
- new file "MT/log" can be edited while you work,
sets default changelog. (no change in behaviour if
you do not edit it.) Thanks to Jeremy Cowgar
<jeremy@cowgar.com>.
- monotone now stores default netsync
server/collection, initialized on first use of
netsync.
- you no longer need to manually import server
keys, monotone will fetch the key from the server on
first netsync.
- monotone keeps track of keys of servers you have
previously synced with, to prevent man-in-the-middle
attacks.
- several powerful new "automate" commands added.
- new command 'ls known', lists files that are under version
control. Thanks to Florian Weimer <fw@deneb.enyo.de>.
- preliminary "inodeprints" functionality -- speeds up diff,
status, etc. No UI or documentation yet -- in a working
copy, 'touch MT/inodeprints' to enable, then commit or
update to populate cache.
- UI improvements:
- Added short options -r, -b, -k, -m.
- default to 'dot' ticker-style when stderr is
not a tty, thanks to Derek Scherger
<derek@echologic.com>.
- New "-@/--xargs" option, helpful when using new
automate commands. Thanks to Richard Levitte
<richard@levitte.org>.
- New "--depth" argument to 'log'. Thanks to Richard
Levitte <richard@levitte.org>.
- 'db info' gives statistics on space usage.
- new command 'dropkey'. Thanks to Jeremey Cowgar
<jeremy@cowgar.com>.
- robustness improvement: if monotone crashes in a working
directory and --dump and --debug were not specified, saves
debug dump to "MT/debug" for analysis, instead of
discarding.
- new contributed scripts: CIA (cia.navi.cx) notification,
email notification, Bash completion.
- 33 new integration tests. total line coverage: ~82%.
- many bug fixes
- Special thanks to Matt Johnston <matt@ucc.asn.au>,
for going above and beyond to track down the last
release blocker.
- upgrading from 0.17 requires only a 'db migrate'.
0.17 release. bug fixes and features.
- many, many robustness improvements
- more careful checking everywhere
- much more thorough test suite
- all revisions subject to careful checks before
entering database
- not yet fully optimized; "pull" may be very
slow and use lots of cpu
- support for "epochs", to safely manage future
rebuilds, hash migration, etc.
- new "db check" command, thanks to Derek Scherger
<derek@echologic.com>.
- now uses sqlite3, thanks to Christof Petig
<christof@petig-baender.de>.
- removes most former size limitations
- "restrictions" support, thanks to Derek Scherger
<derek@echologic.com>.
- most commands now take a list of files to limit
their actions to
- monotone can now be run from anywhere in the working
directory (not just the root)
- new command "monotone setup" required to create a
working directory for a new project
- important security fix -- don't use shell when calling
external merge commands.
- format change for "MT/options", ".mt-attrs"; you may have to
edit these files
- new command "attr" for managing .mt-attrs.
- builds merkle tries in-memory -- netsync starts up many times faster
- start of new "automate" interface, for shell scripts and others.
- new command "cdiff": generates context diffs.
- remove most of now-obsolete manifest/file cert support.
- 60+ new integration tests.
- many portability fixes
- in particular, major win32 cleanups, thanks to Jon
Bright <jon@siliconcircus.com>. win32 is once again
fully and natively supported.
- many bug fixes
- several incompatible changes: see file UPGRADE for migration information
(because libraries are unversioned), and we only need to depend on the
binary libraries (boost-libs); the huge boost dependency disappears.
Bump PKGREVISION to 1.
- 50+ new integration tests
- many NetBSD portability fixes
- release build on gcc 3.4 / FC3
- masses of changeset bugs in 0.15 fixed
Some bogus changesets were generated in the 0.16 development cycle. You
will need to rebuild revision graph.
