"""Show historical log for a branch or subset of a branch.
2079
log is bzr's default tool for exploring the history of a branch.
2080
The branch to use is taken from the first parameter. If no parameters
2081
are given, the branch containing the working directory is logged.
2082
Here are some simple examples::
2084
bzr log log the current branch
2085
bzr log foo.py log a file in its branch
2086
bzr log http://server/branch log a branch on a server
2088
The filtering, ordering and information shown for each revision can
2089
be controlled as explained below. By default, all revisions are
2090
shown sorted (topologically) so that newer revisions appear before
2091
older ones and descendants always appear before ancestors. If displayed,
2092
merged revisions are shown indented under the revision in which they
2097
The log format controls how information about each revision is
2098
displayed. The standard log formats are called ``long``, ``short``
2099
and ``line``. The default is long. See ``bzr help log-formats``
2100
for more details on log formats.
2102
The following options can be used to control what information is
2105
-l N display a maximum of N revisions
2106
-n N display N levels of revisions (0 for all, 1 for collapsed)
2107
-v display a status summary (delta) for each revision
2108
-p display a diff (patch) for each revision
2109
--show-ids display revision-ids (and file-ids), not just revnos
2111
Note that the default number of levels to display is a function of the
2112
log format. If the -n option is not used, the standard log formats show
2113
just the top level (mainline).
2115
Status summaries are shown using status flags like A, M, etc. To see
2116
the changes explained using words like ``added`` and ``modified``
2117
instead, use the -vv option.
2121
To display revisions from oldest to newest, use the --forward option.
2122
In most cases, using this option will have little impact on the total
2123
time taken to produce a log, though --forward does not incrementally
2124
display revisions like --reverse does when it can.
2126
:Revision filtering:
2128
The -r option can be used to specify what revision or range of revisions
2129
to filter against. The various forms are shown below::
2131
-rX display revision X
2132
-rX.. display revision X and later
2133
-r..Y display up to and including revision Y
2134
-rX..Y display from X to Y inclusive
2136
See ``bzr help revisionspec`` for details on how to specify X and Y.
2137
Some common examples are given below::
2139
-r-1 show just the tip
2140
-r-10.. show the last 10 mainline revisions
2141
-rsubmit:.. show what's new on this branch
2142
-rancestor:path.. show changes since the common ancestor of this
2143
branch and the one at location path
2144
-rdate:yesterday.. show changes since yesterday
2146
When logging a range of revisions using -rX..Y, log starts at
2147
revision Y and searches back in history through the primary
2148
("left-hand") parents until it finds X. When logging just the
2149
top level (using -n1), an error is reported if X is not found
2150
along the way. If multi-level logging is used (-n0), X may be
2151
a nested merge revision and the log will be truncated accordingly.
2155
If parameters are given and the first one is not a branch, the log
2156
will be filtered to show only those revisions that changed the
2157
nominated files or directories.
2159
Filenames are interpreted within their historical context. To log a
2160
deleted file, specify a revision range so that the file existed at
2161
the end or start of the range.
2163
Historical context is also important when interpreting pathnames of
2164
renamed files/directories. Consider the following example:
2166
* revision 1: add tutorial.txt
2167
* revision 2: modify tutorial.txt
2168
* revision 3: rename tutorial.txt to guide.txt; add tutorial.txt
2172
* ``bzr log guide.txt`` will log the file added in revision 1
2174
* ``bzr log tutorial.txt`` will log the new file added in revision 3
2176
* ``bzr log -r2 -p tutorial.txt`` will show the changes made to
2177
the original file in revision 2.
2179
* ``bzr log -r2 -p guide.txt`` will display an error message as there
2180
was no file called guide.txt in revision 2.
2182
Renames are always followed by log. By design, there is no need to
2183
explicitly ask for this (and no way to stop logging a file back
2184
until it was last renamed).
2188
The --message option can be used for finding revisions that match a
2189
regular expression in a commit message.
2193
GUI tools and IDEs are often better at exploring history than command
2194
line tools: you may prefer qlog or viz from qbzr or bzr-gtk, the
2195
bzr-explorer shell, or the Loggerhead web interface. See the Plugin
2196
Guide <http://doc.bazaar.canonical.com/plugins/en/> and
2197
<http://wiki.bazaar.canonical.com/IDEIntegration>.
2199
You may find it useful to add the aliases below to ``bazaar.conf``::
2203
top = log -l10 --line
2206
``bzr tip`` will then show the latest revision while ``bzr top``
2207
will show the last 10 mainline revisions. To see the details of a
2208
particular revision X, ``bzr show -rX``.
2210
If you are interested in looking deeper into a particular merge X,
2211
use ``bzr log -n0 -rX``.
2213
``bzr log -v`` on a branch with lots of history is currently
2214
very slow. A fix for this issue is currently under development.
2215
With or without that fix, it is recommended that a revision range
2216
be given when using the -v option.
2218
bzr has a generic full-text matching plugin, bzr-search, that can be
2219
used to find revisions matching user names, commit messages, etc.

Among other features, this plugin can find all revisions containing
2221
a list of words but not others.
2223
When exploring non-mainline history on large projects with deep
2224
history, the performance of log can be greatly improved by installing
2225
the historycache plugin. This plugin buffers historical information
2226
trading disk space for faster speed.

Giving a list of files will revert only those files. Otherwise, all files
4091
will be reverted. If the revision is not specified with '--revision', the
4092
last committed revision is used.
4094
To remove only some changes, without reverting to a prior version, use
4095
merge instead. For example, "merge . --revision -2..-3" will remove the
4096
changes introduced by -2, without affecting the changes introduced by -1.
4097
Or to remove certain changes on a hunk-by-hunk basis, see the Shelf plugin.
4099
By default, any files that have been manually changed will be backed up
4100
first. (Files changed only by merge are not backed up.) Backup files have
4101
'.~#~' appended to their name, where # is a number.
4103
When you provide files, you can use their current pathname or the pathname
4104
from the target revision. So you can use revert to "undelete" a file by
4105
name. If you name a directory, all the contents of that directory will be
4108
If you have newly added files since the target revision, they will be
4109
removed. If the files to be removed have been changed, backups will be
4110

4113
The working tree contains a list of revisions that have been merged but
4114
not yet committed. These revisions will be included as additional parents
4115
of the next commit. Normally, using revert clears that list as well as
4116
reverting the files. If any files are specified, revert leaves the list
4117
of uncommitted merges alone and reverts only the files. Use ``bzr revert
4118
.`` in the tree root to revert all files but keep the recorded merges,
4119
and ``bzr revert --forget-merges`` to clear the pending merge list without
4120
reverting any files.
4122
Using "bzr revert --forget-merges", it is possible to apply all of the
4123
changes from a branch in a single revision. To do this, perform the merge
4124
as desired. Then doing revert with the "--forget-merges" option will keep
4125
the content of the tree as it was, but it will clear the list of pending
4126
merges. The next commit will then contain all of the changes that are
4127
present in the other branch, but without any other parent revisions.

5032
A merge directive provides many things needed for requesting merges:
5034
* A machine-readable description of the merge to perform
5036
* An optional patch that is a preview of the changes requested
5038
* An optional bundle of revision data, so that the changes can be applied
5039
directly from the merge directive, without retrieving data from a
5042
`bzr send` creates a compact data set that, when applied using bzr
5043
merge, has the same effect as merging from the source branch.
5045
By default the merge directive is self-contained and can be applied to any
5046
branch containing submit_branch in its ancestory without needing access to
5049
If --no-bundle is specified, then Bazaar doesn't send the contents of the
5050
revisions, but only a structured request to merge from the
5051
public_location. In that case the public_branch is needed and it must be
5052
up-to-date and accessible to the recipient. The public_branch is always
5053
included if known, so that people can check it later.
5055
The submit branch defaults to the parent of the source branch, but can be
5056
overridden. Both submit branch and public branch will be remembered in
5057
branch.conf the first time they are used for a particular branch. The
5058
source branch defaults to that containing the working directory, but can
5059
be changed using --from.
5061
In order to calculate those changes, bzr must analyse the submit branch.
5062
Therefore it is most efficient for the submit branch to be a local mirror.
5063
If a public location is known for the submit_branch, that location is used
5064
in the merge directive.
5066
The default behaviour is to send the merge directive by mail, unless -o is
5067
given, in which case it is sent to a file.
5069
Mail is sent using your preferred mail program. This should be transparent
5070
on Windows (it uses MAPI). On Linux, it requires the xdg-email utility.
5071
If the preferred client can't be found (or used), your editor will be used.
5073
To use a specific mail program, set the mail_client configuration option.
5074
(For Thunderbird 1.5, this works around some bugs.) Supported values for
5075
specific clients are "claws", "evolution", "kmail", "mail.app" (MacOS X's
5076
Mail.app), "mutt", and "thunderbird"; generic options are "default",
5077
"editor", "emacsclient", "mapi", and "xdg-email". Plugins may also add
5080
If mail is being sent, a to address is required. This can be supplied
5081
either on the commandline, by setting the submit_to configuration
5082
option in the branch itself or the child_submit_to configuration option
5083
in the submit branch.
5085
Two formats are currently supported: "4" uses revision bundle format 4 and
5086
merge directive format 2. It is significantly faster and smaller than
5087
older formats. It is compatible with Bazaar 0.19 and later. It is the
5088
default. "0.9" uses revision bundle format 0.9 and merge directive
5089
format 1. It is compatible with Bazaar 0.12 - 0.18.
5091
The merge directives created by bzr send may be applied using bzr merge or
5092
bzr pull by specifying a file containing a merge directive as the location.
5094
bzr send makes extensive use of public locations to map local locations into
5095
URLs that can be used by other people. See `bzr help configuration` to
5096
set them, and use `bzr info` to display them.
