upstream/mercurial-mirror Files · mercurial/help/config.txt

The Mercurial system uses a set of configuration files to control

aspects of its behavior.

Troubleshooting

===============

If you're having problems with your configuration,

:hg:`config --debug` can help you understand what is introducing

a setting into your environment.

See :hg:`help config.syntax` and :hg:`help config.files`

for information about how and where to override things.

Structure

=========

The configuration files use a simple ini-file format. A configuration

file consists of sections, led by a ``[section]`` header and followed

by ``name = value`` entries::

[ui]

username = Firstname Lastname <firstname.lastname@example.net>

verbose = True

The above entries will be referred to as ``ui.username`` and

``ui.verbose``, respectively. See :hg:`help config.syntax`.

Files

=====

Mercurial reads configuration data from several files, if they exist.

These files do not exist by default and you will have to create the

appropriate configuration files yourself:

Local configuration is put into the per-repository ``<repo>/.hg/hgrc`` file.

Global configuration like the username setting is typically put into:

.. container:: windows

- ``%USERPROFILE%\mercurial.ini`` (on Windows)

.. container:: unix.plan9

- ``$HOME/.hgrc`` (on Unix, Plan9)

The names of these files depend on the system on which Mercurial is

installed. ``*.rc`` files from a single directory are read in

alphabetical order, later ones overriding earlier ones. Where multiple

paths are given below, settings from earlier paths override later

ones.

.. container:: verbose.unix

On Unix, the following files are consulted:

- ``<repo>/.hg/hgrc`` (per-repository)

- ``$HOME/.hgrc`` (per-user)

- ``${XDG_CONFIG_HOME:-$HOME/.config}/hg/hgrc`` (per-user)

- ``<install-root>/etc/mercurial/hgrc`` (per-installation)

- ``<install-root>/etc/mercurial/hgrc.d/*.rc`` (per-installation)

- ``/etc/mercurial/hgrc`` (per-system)

- ``/etc/mercurial/hgrc.d/*.rc`` (per-system)

- ``<internal>/default.d/*.rc`` (defaults)

.. container:: verbose.windows

On Windows, the following files are consulted:

- ``<repo>/.hg/hgrc`` (per-repository)

- ``%USERPROFILE%\.hgrc`` (per-user)

- ``%USERPROFILE%\Mercurial.ini`` (per-user)

- ``%HOME%\.hgrc`` (per-user)

- ``%HOME%\Mercurial.ini`` (per-user)

- ``HKEY_LOCAL_MACHINE\SOFTWARE\Mercurial`` (per-installation)

- ``<install-dir>\hgrc.d\*.rc`` (per-installation)

- ``<install-dir>\Mercurial.ini`` (per-installation)

- ``<internal>/default.d/*.rc`` (defaults)

.. note::

The registry key ``HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Mercurial``

is used when running 32-bit Python on 64-bit Windows.

.. container:: windows

On Windows 9x, ``%HOME%`` is replaced by ``%APPDATA%``.

.. container:: verbose.plan9

On Plan9, the following files are consulted:

- ``<repo>/.hg/hgrc`` (per-repository)

- ``$home/lib/hgrc`` (per-user)

- ``<install-root>/lib/mercurial/hgrc`` (per-installation)

- ``<install-root>/lib/mercurial/hgrc.d/*.rc`` (per-installation)

- ``/lib/mercurial/hgrc`` (per-system)

- ``/lib/mercurial/hgrc.d/*.rc`` (per-system)

- ``<internal>/default.d/*.rc`` (defaults)

Per-repository configuration options only apply in a

particular repository. This file is not version-controlled, and

will not get transferred during a "clone" operation. Options in

this file override options in all other configuration files.

.. container:: unix.plan9

On Plan 9 and Unix, most of this file will be ignored if it doesn't

belong to a trusted user or to a trusted group. See

:hg:`help config.trusted` for more details.

Per-user configuration file(s) are for the user running Mercurial. Options

in these files apply to all Mercurial commands executed by this user in any

directory. Options in these files override per-system and per-installation

options.

Per-installation configuration files are searched for in the

directory where Mercurial is installed. ``<install-root>`` is the

parent directory of the **hg** executable (or symlink) being run.

.. container:: unix.plan9

For example, if installed in ``/shared/tools/bin/hg``, Mercurial

will look in ``/shared/tools/etc/mercurial/hgrc``. Options in these

files apply to all Mercurial commands executed by any user in any

directory.

Per-installation configuration files are for the system on

which Mercurial is running. Options in these files apply to all

Mercurial commands executed by any user in any directory. Registry

keys contain PATH-like strings, every part of which must reference

a ``Mercurial.ini`` file or be a directory where ``*.rc`` files will

be read. Mercurial checks each of these locations in the specified

order until one or more configuration files are detected.

Per-system configuration files are for the system on which Mercurial

is running. Options in these files apply to all Mercurial commands

executed by any user in any directory. Options in these files

override per-installation options.

Mercurial comes with some default configuration. The default configuration

files are installed with Mercurial and will be overwritten on upgrades. Default

configuration files should never be edited by users or administrators but can

be overridden in other configuration files. So far the directory only contains

merge tool configuration but packagers can also put other default configuration

there.

Syntax

======

A configuration file consists of sections, led by a ``[section]`` header

and followed by ``name = value`` entries (sometimes called

``configuration keys``)::

[spam]

eggs=ham

green=

eggs

Each line contains one entry. If the lines that follow are indented,

they are treated as continuations of that entry. Leading whitespace is

removed from values. Empty lines are skipped. Lines beginning with

``#`` or ``;`` are ignored and may be used to provide comments.

Configuration keys can be set multiple times, in which case Mercurial

will use the value that was configured last. As an example::

[spam]

eggs=large

ham=serrano

eggs=small

This would set the configuration key named ``eggs`` to ``small``.

It is also possible to define a section multiple times. A section can

be redefined on the same and/or on different configuration files. For

example::

[foo]

eggs=large

ham=serrano

eggs=small

[bar]

eggs=ham

green=

eggs

[foo]

ham=prosciutto

eggs=medium

bread=toasted

This would set the ``eggs``, ``ham``, and ``bread`` configuration keys

of the ``foo`` section to ``medium``, ``prosciutto``, and ``toasted``,

respectively. As you can see there only thing that matters is the last

value that was set for each of the configuration keys.

If a configuration key is set multiple times in different

configuration files the final value will depend on the order in which

the different configuration files are read, with settings from earlier

paths overriding later ones as described on the ``Files`` section

above.

A line of the form ``%include file`` will include ``file`` into the

current configuration file. The inclusion is recursive, which means

that included files can include other files. Filenames are relative to

the configuration file in which the ``%include`` directive is found.

Environment variables and ``~user`` constructs are expanded in

``file``. This lets you do something like::

%include ~/.hgrc.d/$HOST.rc

to include a different configuration file on each computer you use.

A line with ``%unset name`` will remove ``name`` from the current

section, if it has been set previously.

The values are either free-form text strings, lists of text strings,

or Boolean values. Boolean values can be set to true using any of "1",

"yes", "true", or "on" and to false using "0", "no", "false", or "off"

(all case insensitive).

List values are separated by whitespace or comma, except when values are

placed in double quotation marks::

allow_read = "John Doe, PhD", brian, betty

Quotation marks can be escaped by prefixing them with a backslash. Only

quotation marks at the beginning of a word is counted as a quotation

(e.g., ``foo"bar baz`` is the list of ``foo"bar`` and ``baz``).

Sections

========

This section describes the different sections that may appear in a

Mercurial configuration file, the purpose of each section, its possible

keys, and their possible values.

``alias``

---------

Defines command aliases.

Aliases allow you to define your own commands in terms of other

commands (or aliases), optionally including arguments. Positional

arguments in the form of ``$1``, ``$2``, etc. in the alias definition

are expanded by Mercurial before execution. Positional arguments not

already used by ``$N`` in the definition are put at the end of the

command to be executed.

Alias definitions consist of lines of the form::

<alias> = <command> [<argument>]...

For example, this definition::

latest = log --limit 5

creates a new command ``latest`` that shows only the five most recent

changesets. You can define subsequent aliases using earlier ones::

stable5 = latest -b stable

.. note::

It is possible to create aliases with the same names as

existing commands, which will then override the original

definitions. This is almost always a bad idea!

An alias can start with an exclamation point (``!``) to make it a

shell alias. A shell alias is executed with the shell and will let you

run arbitrary commands. As an example, ::

echo = !echo $@

will let you do ``hg echo foo`` to have ``foo`` printed in your

terminal. A better example might be::

purge = !$HG status --no-status --unknown -0 re: | xargs -0 rm -f

which will make ``hg purge`` delete all unknown files in the

repository in the same manner as the purge extension.

Positional arguments like ``$1``, ``$2``, etc. in the alias definition

expand to the command arguments. Unmatched arguments are

removed. ``$0`` expands to the alias name and ``$@`` expands to all

arguments separated by a space. ``"$@"`` (with quotes) expands to all

arguments quoted individually and separated by a space. These expansions

happen before the command is passed to the shell.

Shell aliases are executed in an environment where ``$HG`` expands to

the path of the Mercurial that was used to execute the alias. This is

useful when you want to call further Mercurial commands in a shell

alias, as was done above for the purge alias. In addition,

``$HG_ARGS`` expands to the arguments given to Mercurial. In the ``hg

echo foo`` call above, ``$HG_ARGS`` would expand to ``echo foo``.

.. note::

Some global configuration options such as ``-R`` are

processed before shell aliases and will thus not be passed to

aliases.

``annotate``

------------

Settings used when displaying file annotations. All values are

Booleans and default to False. See :hg:`help config.diff` for

related options for the diff command.

``ignorews``

Ignore white space when comparing lines.

``ignorewseol``

Ignore white space at the end of a line when comparing lines.

``ignorewsamount``

Ignore changes in the amount of white space.

``ignoreblanklines``

Ignore changes whose lines are all blank.

``auth``

--------

Authentication credentials and other authentication-like configuration

for HTTP connections. This section allows you to store usernames and

passwords for use when logging *into* HTTP servers. See

:hg:`help config.web` if you want to configure *who* can login to

your HTTP server.

The following options apply to all hosts.

``cookiefile``

Path to a file containing HTTP cookie lines. Cookies matching a

host will be sent automatically.

The file format uses the Mozilla cookies.txt format, which defines cookies

on their own lines. Each line contains 7 fields delimited by the tab

character (domain, is_domain_cookie, path, is_secure, expires, name,

value). For more info, do an Internet search for "Netscape cookies.txt

format."

Note: the cookies parser does not handle port numbers on domains. You

will need to remove ports from the domain for the cookie to be recognized.

This could result in a cookie being disclosed to an unwanted server.

The cookies file is read-only.

Other options in this section are grouped by name and have the following

format::

where ``<name>`` is used to group arguments into authentication

entries. Example::

foo.prefix = hg.intevation.de/mercurial

foo.username = foo

foo.password = bar

foo.schemes = http https

bar.prefix = secure.example.org

bar.key = path/to/file.key

bar.cert = path/to/file.cert

bar.schemes = https

Supported arguments:

``prefix``

Either ``*`` or a URI prefix with or without the scheme part.

The authentication entry with the longest matching prefix is used

(where ``*`` matches everything and counts as a match of length

1). If the prefix doesn't include a scheme, the match is performed

against the URI with its scheme stripped as well, and the schemes

argument, q.v., is then subsequently consulted.

``username``

Optional. Username to authenticate with. If not given, and the

remote site requires basic or digest authentication, the user will

be prompted for it. Environment variables are expanded in the

username letting you do ``foo.username = $USER``. If the URI

includes a username, only ``[auth]`` entries with a matching

username or without a username will be considered.

``password``

Optional. Password to authenticate with. If not given, and the

remote site requires basic or digest authentication, the user

will be prompted for it.

``key``

Optional. PEM encoded client certificate key file. Environment

variables are expanded in the filename.

``cert``

Optional. PEM encoded client certificate chain file. Environment

variables are expanded in the filename.

``schemes``

Optional. Space separated list of URI schemes to use this

authentication entry with. Only used if the prefix doesn't include

a scheme. Supported schemes are http and https. They will match

static-http and static-https respectively, as well.

(default: https)

If no suitable authentication entry is found, the user is prompted

for credentials as usual if required by the remote.

``color``

---------

Configure the Mercurial color mode. For details about how to define your custom

effect and style see :hg:`help color`.

``mode``

String: control the method used to output color. One of ``auto``, ``ansi``,

``win32``, ``terminfo`` or ``debug``. In auto mode, Mercurial will

use ANSI mode by default (or win32 mode prior to Windows 10) if it detects a

terminal. Any invalid value will disable color.

``pagermode``

String: optional override of ``color.mode`` used with pager.

On some systems, terminfo mode may cause problems when using

color with ``less -R`` as a pager program. less with the -R option

will only display ECMA-48 color codes, and terminfo mode may sometimes

emit codes that less doesn't understand. You can work around this by

either using ansi mode (or auto mode), or by using less -r (which will

pass through all terminal control codes, not just color control

codes).

On some systems (such as MSYS in Windows), the terminal may support

a different color mode than the pager program.

``commands``

------------

``status.relative``

Make paths in :hg:`status` output relative to the current directory.

(default: False)

``status.terse``

Default value for the --terse flag, which condenes status output.

(default: empty)

``update.check``

Determines what level of checking :hg:`update` will perform before moving

to a destination revision. Valid values are ``abort``, ``none``,

``linear``, and ``noconflict``. ``abort`` always fails if the working

directory has uncommitted changes. ``none`` performs no checking, and may

result in a merge with uncommitted changes. ``linear`` allows any update

as long as it follows a straight line in the revision history, and may

trigger a merge with uncommitted changes. ``noconflict`` will allow any

update which would not trigger a merge with uncommitted changes, if any

are present.

(default: ``linear``)

``update.requiredest``

Require that the user pass a destination when running :hg:`update`.

For example, :hg:`update .::` will be allowed, but a plain :hg:`update`

will be disallowed.

(default: False)

``committemplate``

------------------

``changeset``

String: configuration in this section is used as the template to

customize the text shown in the editor when committing.

In addition to pre-defined template keywords, commit log specific one

below can be used for customization:

``extramsg``

String: Extra message (typically 'Leave message empty to abort

commit.'). This may be changed by some commands or extensions.

For example, the template configuration below shows as same text as

one shown by default::

[committemplate]

changeset = {desc}\n\n

HG: Enter commit message. Lines beginning with 'HG:' are removed.

HG: {extramsg}

HG: --

HG: user: {author}\n{ifeq(p2rev, "-1", "",

"HG: branch merge\n")

}HG: branch '{branch}'\n{if(activebookmark,

"HG: bookmark '{activebookmark}'\n") }{subrepos %

"HG: subrepo {subrepo}\n" }{file_adds %

"HG: added {file}\n" }{file_mods %

"HG: changed {file}\n" }{file_dels %

"HG: removed {file}\n" }{if(files, "",

"HG: no files changed\n")}

``diff()``

String: show the diff (see :hg:`help templates` for detail)

Sometimes it is helpful to show the diff of the changeset in the editor without

having to prefix 'HG: ' to each line so that highlighting works correctly. For

this, Mercurial provides a special string which will ignore everything below

it::

HG: ------------------------ >8 ------------------------

For example, the template configuration below will show the diff below the

extra message::

[committemplate]

changeset = {desc}\n\n

HG: Enter commit message. Lines beginning with 'HG:' are removed.

HG: {extramsg}

HG: ------------------------ >8 ------------------------

HG: Do not touch the line above.

HG: Everything below will be removed.

{diff()}

.. note::

For some problematic encodings (see :hg:`help win32mbcs` for

detail), this customization should be configured carefully, to

avoid showing broken characters.

For example, if a multibyte character ending with backslash (0x5c) is

followed by the ASCII character 'n' in the customized template,

the sequence of backslash and 'n' is treated as line-feed unexpectedly

(and the multibyte character is broken, too).

Customized template is used for commands below (``--edit`` may be

required):

- :hg:`backout`

- :hg:`commit`

- :hg:`fetch` (for merge commit only)

- :hg:`graft`

- :hg:`histedit`

- :hg:`import`

- :hg:`qfold`, :hg:`qnew` and :hg:`qrefresh`

- :hg:`rebase`

- :hg:`shelve`

- :hg:`sign`

- :hg:`tag`

- :hg:`transplant`

Configuring items below instead of ``changeset`` allows showing

customized message only for specific actions, or showing different

messages for each action.

- ``changeset.backout`` for :hg:`backout`

- ``changeset.commit.amend.merge`` for :hg:`commit --amend` on merges

- ``changeset.commit.amend.normal`` for :hg:`commit --amend` on other

- ``changeset.commit.normal.merge`` for :hg:`commit` on merges

- ``changeset.commit.normal.normal`` for :hg:`commit` on other

- ``changeset.fetch`` for :hg:`fetch` (impling merge commit)

- ``changeset.gpg.sign`` for :hg:`sign`

- ``changeset.graft`` for :hg:`graft`

- ``changeset.histedit.edit`` for ``edit`` of :hg:`histedit`

- ``changeset.histedit.fold`` for ``fold`` of :hg:`histedit`

- ``changeset.histedit.mess`` for ``mess`` of :hg:`histedit`

- ``changeset.histedit.pick`` for ``pick`` of :hg:`histedit`

- ``changeset.import.bypass`` for :hg:`import --bypass`

- ``changeset.import.normal.merge`` for :hg:`import` on merges

- ``changeset.import.normal.normal`` for :hg:`import` on other

- ``changeset.mq.qnew`` for :hg:`qnew`

- ``changeset.mq.qfold`` for :hg:`qfold`

- ``changeset.mq.qrefresh`` for :hg:`qrefresh`

- ``changeset.rebase.collapse`` for :hg:`rebase --collapse`

- ``changeset.rebase.merge`` for :hg:`rebase` on merges

- ``changeset.rebase.normal`` for :hg:`rebase` on other

- ``changeset.shelve.shelve`` for :hg:`shelve`

- ``changeset.tag.add`` for :hg:`tag` without ``--remove``

- ``changeset.tag.remove`` for :hg:`tag --remove`

- ``changeset.transplant.merge`` for :hg:`transplant` on merges

- ``changeset.transplant.normal`` for :hg:`transplant` on other

These dot-separated lists of names are treated as hierarchical ones.

For example, ``changeset.tag.remove`` customizes the commit message

only for :hg:`tag --remove`, but ``changeset.tag`` customizes the

commit message for :hg:`tag` regardless of ``--remove`` option.

When the external editor is invoked for a commit, the corresponding

dot-separated list of names without the ``changeset.`` prefix

(e.g. ``commit.normal.normal``) is in the ``HGEDITFORM`` environment

variable.

In this section, items other than ``changeset`` can be referred from

others. For example, the configuration to list committed files up

below can be referred as ``{listupfiles}``::

[committemplate]

listupfiles = {file_adds %

"HG: added {file}\n" }{file_mods %

"HG: changed {file}\n" }{file_dels %

"HG: removed {file}\n" }{if(files, "",

"HG: no files changed\n")}

``decode/encode``

-----------------

Filters for transforming files on checkout/checkin. This would

typically be used for newline processing or other

localization/canonicalization of files.

Filters consist of a filter pattern followed by a filter command.

Filter patterns are globs by default, rooted at the repository root.

For example, to match any file ending in ``.txt`` in the root

directory only, use the pattern ``*.txt``. To match any file ending

in ``.c`` anywhere in the repository, use the pattern ``**.c``.

For each file only the first matching filter applies.

The filter command can start with a specifier, either ``pipe:`` or

``tempfile:``. If no specifier is given, ``pipe:`` is used by default.

A ``pipe:`` command must accept data on stdin and return the transformed

data on stdout.

Pipe example::

[encode]

# uncompress gzip files on checkin to improve delta compression

# note: not necessarily a good idea, just an example

*.gz = pipe: gunzip

[decode]

# recompress gzip files when writing them to the working dir (we

# can safely omit "pipe:", because it's the default)

*.gz = gzip

A ``tempfile:`` command is a template. The string ``INFILE`` is replaced

with the name of a temporary file that contains the data to be

filtered by the command. The string ``OUTFILE`` is replaced with the name

of an empty temporary file, where the filtered data must be written by

the command.

.. container:: windows

.. note::

The tempfile mechanism is recommended for Windows systems,

where the standard shell I/O redirection operators often have

strange effects and may corrupt the contents of your files.

This filter mechanism is used internally by the ``eol`` extension to

translate line ending characters between Windows (CRLF) and Unix (LF)

format. We suggest you use the ``eol`` extension for convenience.

``defaults``

------------

(defaults are deprecated. Don't use them. Use aliases instead.)

Use the ``[defaults]`` section to define command defaults, i.e. the

default options/arguments to pass to the specified commands.

The following example makes :hg:`log` run in verbose mode, and

:hg:`status` show only the modified files, by default::

[defaults]

log = -v

status = -m

The actual commands, instead of their aliases, must be used when

defining command defaults. The command defaults will also be applied

to the aliases of the commands defined.

``diff``

--------

Settings used when displaying diffs. Everything except for ``unified``

is a Boolean and defaults to False. See :hg:`help config.annotate`

for related options for the annotate command.

``git``

Use git extended diff format.

``nobinary``

Omit git binary patches.

``nodates``

Don't include dates in diff headers.

``noprefix``

Omit 'a/' and 'b/' prefixes from filenames. Ignored in plain mode.

``showfunc``

Show which function each change is in.

``ignorews``

Ignore white space when comparing lines.

``ignorewsamount``

Ignore changes in the amount of white space.

``ignoreblanklines``

Ignore changes whose lines are all blank.

``unified``

Number of lines of context to show.

``word-diff``

Highlight changed words.

``email``

---------

Settings for extensions that send email messages.

``from``

Optional. Email address to use in "From" header and SMTP envelope

of outgoing messages.

``to``

Optional. Comma-separated list of recipients' email addresses.

``cc``

Optional. Comma-separated list of carbon copy recipients'

email addresses.

``bcc``

Optional. Comma-separated list of blind carbon copy recipients'

email addresses.

``method``

Optional. Method to use to send email messages. If value is ``smtp``

(default), use SMTP (see the ``[smtp]`` section for configuration).

Otherwise, use as name of program to run that acts like sendmail

(takes ``-f`` option for sender, list of recipients on command line,

message on stdin). Normally, setting this to ``sendmail`` or

``/usr/sbin/sendmail`` is enough to use sendmail to send messages.

``charsets``

Optional. Comma-separated list of character sets considered

convenient for recipients. Addresses, headers, and parts not

containing patches of outgoing messages will be encoded in the

first character set to which conversion from local encoding

(``$HGENCODING``, ``ui.fallbackencoding``) succeeds. If correct

conversion fails, the text in question is sent as is.

(default: '')

Order of outgoing email character sets:

1. ``us-ascii``: always first, regardless of settings

2. ``email.charsets``: in order given by user

3. ``ui.fallbackencoding``: if not in email.charsets

4. ``$HGENCODING``: if not in email.charsets

5. ``utf-8``: always last, regardless of settings

Email example::

[email]

from = Joseph User <joe.user@example.com>

method = /usr/sbin/sendmail

# charsets for western Europeans

# us-ascii, utf-8 omitted, as they are tried first and last

charsets = iso-8859-1, iso-8859-15, windows-1252

``extensions``

--------------

Mercurial has an extension mechanism for adding new features. To

enable an extension, create an entry for it in this section.

If you know that the extension is already in Python's search path,

you can give the name of the module, followed by ``=``, with nothing

after the ``=``.

Otherwise, give a name that you choose, followed by ``=``, followed by

the path to the ``.py`` file (including the file name extension) that

defines the extension.

To explicitly disable an extension that is enabled in an hgrc of

broader scope, prepend its path with ``!``, as in ``foo = !/ext/path``

or ``foo = !`` when path is not supplied.

Example for ``~/.hgrc``::

[extensions]

# (the churn extension will get loaded from Mercurial's path)

churn =

# (this extension will get loaded from the file specified)

myfeature = ~/.hgext/myfeature.py

``format``

----------

``usegeneraldelta``

Enable or disable the "generaldelta" repository format which improves

repository compression by allowing "revlog" to store delta against arbitrary

revision instead of the previous stored one. This provides significant

improvement for repositories with branches.

Repositories with this on-disk format require Mercurial version 1.9.

Enabled by default.

``dotencode``

Enable or disable the "dotencode" repository format which enhances

the "fncache" repository format (which has to be enabled to use

dotencode) to avoid issues with filenames starting with ._ on

Mac OS X and spaces on Windows.

Repositories with this on-disk format require Mercurial version 1.7.

Enabled by default.

``usefncache``

Enable or disable the "fncache" repository format which enhances

the "store" repository format (which has to be enabled to use

fncache) to allow longer filenames and avoids using Windows

reserved names, e.g. "nul".

Repositories with this on-disk format require Mercurial version 1.1.

Enabled by default.

``usestore``

Enable or disable the "store" repository format which improves

compatibility with systems that fold case or otherwise mangle

filenames. Disabling this option will allow you to store longer filenames

in some situations at the expense of compatibility.

Repositories with this on-disk format require Mercurial version 0.9.4.

Enabled by default.

``graph``

---------

Web graph view configuration. This section let you change graph

elements display properties by branches, for instance to make the

``default`` branch stand out.

Each line has the following format::

where ``<branch>`` is the name of the branch being

customized. Example::

[graph]

# 2px width

default.width = 2

# red color

default.color = FF0000

Supported arguments:

``width``

Set branch edges width in pixels.

``color``

Set branch edges color in hexadecimal RGB notation.

``hooks``

---------

Commands or Python functions that get automatically executed by

various actions such as starting or finishing a commit. Multiple

hooks can be run for the same action by appending a suffix to the

action. Overriding a site-wide hook can be done by changing its

value or setting it to an empty string. Hooks can be prioritized

by adding a prefix of ``priority.`` to the hook name on a new line

and setting the priority. The default priority is 0.

Example ``.hg/hgrc``::

[hooks]

# update working directory after adding changesets

changegroup.update = hg update

# do not use the site-wide hook

incoming =

incoming.email = /my/email/hook

incoming.autobuild = /my/build/hook

# force autobuild hook to run before other incoming hooks

priority.incoming.autobuild = 1

Most hooks are run with environment variables set that give useful

additional information. For each hook below, the environment variables

it is passed are listed with names in the form ``$HG_foo``. The

``$HG_HOOKTYPE`` and ``$HG_HOOKNAME`` variables are set for all hooks.

They contain the type of hook which triggered the run and the full name

of the hook in the config, respectively. In the example above, this will

be ``$HG_HOOKTYPE=incoming`` and ``$HG_HOOKNAME=incoming.email``.

.. container:: windows

Some basic Unix syntax is supported for portability, including ``$VAR``

and ``${VAR}`` style variables. To use a literal ``$``, it must be

escaped with a back slash or inside of a strong quote. This can be

disabled by adding a prefix of ``tonative.`` to the hook name on a new

line, and setting it to ``False``. For example::

[hooks]

incoming.autobuild = /my/build/hook

# disable translation to cmd.exe syntax for autobuild hook

tonative.incoming.autobuild = False

``changegroup``

Run after a changegroup has been added via push, pull or unbundle. The ID of

the first new changeset is in ``$HG_NODE`` and last is in ``$HG_NODE_LAST``.

The URL from which changes came is in ``$HG_URL``.

``commit``

Run after a changeset has been created in the local repository. The ID

of the newly created changeset is in ``$HG_NODE``. Parent changeset

IDs are in ``$HG_PARENT1`` and ``$HG_PARENT2``.

``incoming``

Run after a changeset has been pulled, pushed, or unbundled into

the local repository. The ID of the newly arrived changeset is in

``$HG_NODE``. The URL that was source of the changes is in ``$HG_URL``.

``outgoing``

Run after sending changes from the local repository to another. The ID of

first changeset sent is in ``$HG_NODE``. The source of operation is in

``$HG_SOURCE``. Also see :hg:`help config.hooks.preoutgoing`.

``post-<command>``

Run after successful invocations of the associated command. The

contents of the command line are passed as ``$HG_ARGS`` and the result

code in ``$HG_RESULT``. Parsed command line arguments are passed as

``$HG_PATS`` and ``$HG_OPTS``. These contain string representations of

the python data internally passed to <command>. ``$HG_OPTS`` is a

dictionary of options (with unspecified options set to their defaults).

``$HG_PATS`` is a list of arguments. Hook failure is ignored.

``fail-<command>``

Run after a failed invocation of an associated command. The contents

of the command line are passed as ``$HG_ARGS``. Parsed command line

arguments are passed as ``$HG_PATS`` and ``$HG_OPTS``. These contain

string representations of the python data internally passed to

<command>. ``$HG_OPTS`` is a dictionary of options (with unspecified

options set to their defaults). ``$HG_PATS`` is a list of arguments.

Hook failure is ignored.

``pre-<command>``

Run before executing the associated command. The contents of the

command line are passed as ``$HG_ARGS``. Parsed command line arguments

are passed as ``$HG_PATS`` and ``$HG_OPTS``. These contain string

representations of the data internally passed to <command>. ``$HG_OPTS``

is a dictionary of options (with unspecified options set to their

defaults). ``$HG_PATS`` is a list of arguments. If the hook returns

failure, the command doesn't execute and Mercurial returns the failure

code.

``prechangegroup``

Run before a changegroup is added via push, pull or unbundle. Exit

status 0 allows the changegroup to proceed. A non-zero status will

cause the push, pull or unbundle to fail. The URL from which changes

will come is in ``$HG_URL``.

``precommit``

Run before starting a local commit. Exit status 0 allows the

commit to proceed. A non-zero status will cause the commit to fail.

Parent changeset IDs are in ``$HG_PARENT1`` and ``$HG_PARENT2``.

``prelistkeys``

Run before listing pushkeys (like bookmarks) in the

repository. A non-zero status will cause failure. The key namespace is

in ``$HG_NAMESPACE``.

``preoutgoing``

Run before collecting changes to send from the local repository to

another. A non-zero status will cause failure. This lets you prevent

pull over HTTP or SSH. It can also prevent propagating commits (via

local pull, push (outbound) or bundle commands), but not completely,

since you can just copy files instead. The source of operation is in

``$HG_SOURCE``. If "serve", the operation is happening on behalf of a remote

SSH or HTTP repository. If "push", "pull" or "bundle", the operation

is happening on behalf of a repository on same system.

``prepushkey``

Run before a pushkey (like a bookmark) is added to the

repository. A non-zero status will cause the key to be rejected. The

key namespace is in ``$HG_NAMESPACE``, the key is in ``$HG_KEY``,

the old value (if any) is in ``$HG_OLD``, and the new value is in

``$HG_NEW``.

``pretag``

Run before creating a tag. Exit status 0 allows the tag to be

created. A non-zero status will cause the tag to fail. The ID of the

changeset to tag is in ``$HG_NODE``. The name of tag is in ``$HG_TAG``. The

tag is local if ``$HG_LOCAL=1``, or in the repository if ``$HG_LOCAL=0``.

``pretxnopen``

Run before any new repository transaction is open. The reason for the

transaction will be in ``$HG_TXNNAME``, and a unique identifier for the

transaction will be in ``HG_TXNID``. A non-zero status will prevent the

transaction from being opened.

``pretxnclose``

Run right before the transaction is actually finalized. Any repository change

will be visible to the hook program. This lets you validate the transaction

content or change it. Exit status 0 allows the commit to proceed. A non-zero

status will cause the transaction to be rolled back. The reason for the

transaction opening will be in ``$HG_TXNNAME``, and a unique identifier for

the transaction will be in ``HG_TXNID``. The rest of the available data will

vary according the transaction type. New changesets will add ``$HG_NODE``

(the ID of the first added changeset), ``$HG_NODE_LAST`` (the ID of the last

added changeset), ``$HG_URL`` and ``$HG_SOURCE`` variables. Bookmark and

phase changes will set ``HG_BOOKMARK_MOVED`` and ``HG_PHASES_MOVED`` to ``1``

respectively, etc.

``pretxnclose-bookmark``

Run right before a bookmark change is actually finalized. Any repository

change will be visible to the hook program. This lets you validate the

transaction content or change it. Exit status 0 allows the commit to

proceed. A non-zero status will cause the transaction to be rolled back.

The name of the bookmark will be available in ``$HG_BOOKMARK``, the new

bookmark location will be available in ``$HG_NODE`` while the previous

location will be available in ``$HG_OLDNODE``. In case of a bookmark

creation ``$HG_OLDNODE`` will be empty. In case of deletion ``$HG_NODE``

will be empty.

In addition, the reason for the transaction opening will be in

``$HG_TXNNAME``, and a unique identifier for the transaction will be in

``HG_TXNID``.

``pretxnclose-phase``

Run right before a phase change is actually finalized. Any repository change

will be visible to the hook program. This lets you validate the transaction

content or change it. Exit status 0 allows the commit to proceed. A non-zero

status will cause the transaction to be rolled back. The hook is called

multiple times, once for each revision affected by a phase change.

The affected node is available in ``$HG_NODE``, the phase in ``$HG_PHASE``

while the previous ``$HG_OLDPHASE``. In case of new node, ``$HG_OLDPHASE``

will be empty. In addition, the reason for the transaction opening will be in

``$HG_TXNNAME``, and a unique identifier for the transaction will be in

``HG_TXNID``. The hook is also run for newly added revisions. In this case

the ``$HG_OLDPHASE`` entry will be empty.

``txnclose``

Run after any repository transaction has been committed. At this

point, the transaction can no longer be rolled back. The hook will run

after the lock is released. See :hg:`help config.hooks.pretxnclose` for

details about available variables.

``txnclose-bookmark``

Run after any bookmark change has been committed. At this point, the

transaction can no longer be rolled back. The hook will run after the lock

is released. See :hg:`help config.hooks.pretxnclose-bookmark` for details

about available variables.

``txnclose-phase``

Run after any phase change has been committed. At this point, the

transaction can no longer be rolled back. The hook will run after the lock

is released. See :hg:`help config.hooks.pretxnclose-phase` for details about

available variables.

``txnabort``

Run when a transaction is aborted. See :hg:`help config.hooks.pretxnclose`

for details about available variables.

``pretxnchangegroup``

Run after a changegroup has been added via push, pull or unbundle, but before

the transaction has been committed. The changegroup is visible to the hook

program. This allows validation of incoming changes before accepting them.

The ID of the first new changeset is in ``$HG_NODE`` and last is in

``$HG_NODE_LAST``. Exit status 0 allows the transaction to commit. A non-zero

status will cause the transaction to be rolled back, and the push, pull or

unbundle will fail. The URL that was the source of changes is in ``$HG_URL``.

``pretxncommit``

Run after a changeset has been created, but before the transaction is

committed. The changeset is visible to the hook program. This allows

validation of the commit message and changes. Exit status 0 allows the

commit to proceed. A non-zero status will cause the transaction to

be rolled back. The ID of the new changeset is in ``$HG_NODE``. The parent

changeset IDs are in ``$HG_PARENT1`` and ``$HG_PARENT2``.

``preupdate``

Run before updating the working directory. Exit status 0 allows

the update to proceed. A non-zero status will prevent the update.

The changeset ID of first new parent is in ``$HG_PARENT1``. If updating to a

merge, the ID of second new parent is in ``$HG_PARENT2``.

``listkeys``

Run after listing pushkeys (like bookmarks) in the repository. The

key namespace is in ``$HG_NAMESPACE``. ``$HG_VALUES`` is a

dictionary containing the keys and values.

``pushkey``

Run after a pushkey (like a bookmark) is added to the

repository. The key namespace is in ``$HG_NAMESPACE``, the key is in

``$HG_KEY``, the old value (if any) is in ``$HG_OLD``, and the new

value is in ``$HG_NEW``.

``tag``

Run after a tag is created. The ID of the tagged changeset is in ``$HG_NODE``.

The name of tag is in ``$HG_TAG``. The tag is local if ``$HG_LOCAL=1``, or in

the repository if ``$HG_LOCAL=0``.

``update``

Run after updating the working directory. The changeset ID of first

new parent is in ``$HG_PARENT1``. If updating to a merge, the ID of second new

parent is in ``$HG_PARENT2``. If the update succeeded, ``$HG_ERROR=0``. If the

update failed (e.g. because conflicts were not resolved), ``$HG_ERROR=1``.

.. note::

It is generally better to use standard hooks rather than the

generic pre- and post- command hooks, as they are guaranteed to be

called in the appropriate contexts for influencing transactions.

Also, hooks like "commit" will be called in all contexts that

generate a commit (e.g. tag) and not just the commit command.

.. note::

Environment variables with empty values may not be passed to

hooks on platforms such as Windows. As an example, ``$HG_PARENT2``

will have an empty value under Unix-like platforms for non-merge

changesets, while it will not be available at all under Windows.

The syntax for Python hooks is as follows::

hookname = python:modulename.submodule.callable

hookname = python:/path/to/python/module.py:callable

Python hooks are run within the Mercurial process. Each hook is

called with at least three keyword arguments: a ui object (keyword

``ui``), a repository object (keyword ``repo``), and a ``hooktype``

keyword that tells what kind of hook is used. Arguments listed as

environment variables above are passed as keyword arguments, with no

``HG_`` prefix, and names in lower case.

If a Python hook returns a "true" value or raises an exception, this

is treated as a failure.

``hostfingerprints``

--------------------

(Deprecated. Use ``[hostsecurity]``'s ``fingerprints`` options instead.)

Fingerprints of the certificates of known HTTPS servers.

A HTTPS connection to a server with a fingerprint configured here will

only succeed if the servers certificate matches the fingerprint.

This is very similar to how ssh known hosts works.

The fingerprint is the SHA-1 hash value of the DER encoded certificate.

Multiple values can be specified (separated by spaces or commas). This can

be used to define both old and new fingerprints while a host transitions

to a new certificate.

The CA chain and web.cacerts is not used for servers with a fingerprint.

For example::

[hostfingerprints]

hg.intevation.de = fc:e2:8d:d9:51:cd:cb:c1:4d:18:6b:b7:44:8d:49:72:57:e6:cd:33

hg.intevation.org = fc:e2:8d:d9:51:cd:cb:c1:4d:18:6b:b7:44:8d:49:72:57:e6:cd:33

``hostsecurity``

----------------

Used to specify global and per-host security settings for connecting to

other machines.

The following options control default behavior for all hosts.

``ciphers``

Defines the cryptographic ciphers to use for connections.

Value must be a valid OpenSSL Cipher List Format as documented at

https://www.openssl.org/docs/manmaster/apps/ciphers.html#CIPHER-LIST-FORMAT.

This setting is for advanced users only. Setting to incorrect values

can significantly lower connection security or decrease performance.

You have been warned.

This option requires Python 2.7.

``minimumprotocol``

Defines the minimum channel encryption protocol to use.

By default, the highest version of TLS supported by both client and server

is used.

Allowed values are: ``tls1.0``, ``tls1.1``, ``tls1.2``.

When running on an old Python version, only ``tls1.0`` is allowed since

old versions of Python only support up to TLS 1.0.

When running a Python that supports modern TLS versions, the default is

``tls1.1``. ``tls1.0`` can still be used to allow TLS 1.0. However, this

weakens security and should only be used as a feature of last resort if

a server does not support TLS 1.1+.

Options in the ``[hostsecurity]`` section can have the form

``hostname``:``setting``. This allows multiple settings to be defined on a

per-host basis.

The following per-host settings can be defined.

``ciphers``

This behaves like ``ciphers`` as described above except it only applies

to the host on which it is defined.

``fingerprints``

A list of hashes of the DER encoded peer/remote certificate. Values have

the form ``algorithm``:``fingerprint``. e.g.

``sha256:c3ab8ff13720e8ad9047dd39466b3c8974e592c2fa383d4a3960714caef0c4f2``.

In addition, colons (``:``) can appear in the fingerprint part.

The following algorithms/prefixes are supported: ``sha1``, ``sha256``,

``sha512``.

Use of ``sha256`` or ``sha512`` is preferred.

If a fingerprint is specified, the CA chain is not validated for this

host and Mercurial will require the remote certificate to match one

of the fingerprints specified. This means if the server updates its

certificate, Mercurial will abort until a new fingerprint is defined.

This can provide stronger security than traditional CA-based validation

at the expense of convenience.

This option takes precedence over ``verifycertsfile``.

``minimumprotocol``

This behaves like ``minimumprotocol`` as described above except it

only applies to the host on which it is defined.

``verifycertsfile``

Path to file a containing a list of PEM encoded certificates used to

verify the server certificate. Environment variables and ``~user``

constructs are expanded in the filename.

The server certificate or the certificate's certificate authority (CA)

must match a certificate from this file or certificate verification

will fail and connections to the server will be refused.

If defined, only certificates provided by this file will be used:

``web.cacerts`` and any system/default certificates will not be

used.

This option has no effect if the per-host ``fingerprints`` option

is set.

The format of the file is as follows::

-----BEGIN CERTIFICATE-----

... (certificate in base64 PEM encoding) ...

-----END CERTIFICATE-----

-----BEGIN CERTIFICATE-----

... (certificate in base64 PEM encoding) ...

-----END CERTIFICATE-----

For example::

[hostsecurity]

hg.example.com:fingerprints = sha256:c3ab8ff13720e8ad9047dd39466b3c8974e592c2fa383d4a3960714caef0c4f2

hg2.example.com:fingerprints = sha1:914f1aff87249c09b6859b88b1906d30756491ca, sha1:fc:e2:8d:d9:51:cd:cb:c1:4d:18:6b:b7:44:8d:49:72:57:e6:cd:33

hg3.example.com:fingerprints = sha256:9a:b0:dc:e2:75:ad:8a:b7:84:58:e5:1f:07:32:f1:87:e6:bd:24:22:af:b7:ce:8e:9c:b4:10:cf:b9:f4:0e:d2

foo.example.com:verifycertsfile = /etc/ssl/trusted-ca-certs.pem

To change the default minimum protocol version to TLS 1.2 but to allow TLS 1.1

when connecting to ``hg.example.com``::

[hostsecurity]

minimumprotocol = tls1.2

hg.example.com:minimumprotocol = tls1.1

``http_proxy``

--------------

Used to access web-based Mercurial repositories through a HTTP

proxy.

``host``

Host name and (optional) port of the proxy server, for example

"myproxy:8000".

``no``

Optional. Comma-separated list of host names that should bypass

the proxy.

``passwd``

Optional. Password to authenticate with at the proxy server.

``user``

Optional. User name to authenticate with at the proxy server.

``always``

Optional. Always use the proxy, even for localhost and any entries

in ``http_proxy.no``. (default: False)

``merge``

---------

This section specifies behavior during merges and updates.

``checkignored``

Controls behavior when an ignored file on disk has the same name as a tracked

file in the changeset being merged or updated to, and has different

contents. Options are ``abort``, ``warn`` and ``ignore``. With ``abort``,

abort on such files. With ``warn``, warn on such files and back them up as

``.orig``. With ``ignore``, don't print a warning and back them up as

``.orig``. (default: ``abort``)

``checkunknown``

Controls behavior when an unknown file that isn't ignored has the same name

as a tracked file in the changeset being merged or updated to, and has

different contents. Similar to ``merge.checkignored``, except for files that

are not ignored. (default: ``abort``)

``on-failure``

When set to ``continue`` (the default), the merge process attempts to

merge all unresolved files using the merge chosen tool, regardless of

whether previous file merge attempts during the process succeeded or not.

Setting this to ``prompt`` will prompt after any merge failure continue

or halt the merge process. Setting this to ``halt`` will automatically

halt the merge process on any merge tool failure. The merge process

can be restarted by using the ``resolve`` command. When a merge is

halted, the repository is left in a normal ``unresolved`` merge state.

(default: ``continue``)

``merge-patterns``

------------------

This section specifies merge tools to associate with particular file

patterns. Tools matched here will take precedence over the default

merge tool. Patterns are globs by default, rooted at the repository

root.

Example::

[merge-patterns]

**.c = kdiff3

**.jpg = myimgmerge

``merge-tools``

---------------

This section configures external merge tools to use for file-level

merges. This section has likely been preconfigured at install time.

Use :hg:`config merge-tools` to check the existing configuration.

Also see :hg:`help merge-tools` for more details.

Example ``~/.hgrc``::

[merge-tools]

# Override stock tool location

kdiff3.executable = ~/bin/kdiff3

# Specify command line

kdiff3.args = $base $local $other -o $output

# Give higher priority

kdiff3.priority = 1

# Changing the priority of preconfigured tool

meld.priority = 0

# Disable a preconfigured tool

vimdiff.disabled = yes

# Define new tool

myHtmlTool.args = -m $local $other $base $output

myHtmlTool.regkey = Software\FooSoftware\HtmlMerge

myHtmlTool.priority = 1

Supported arguments:

``priority``

The priority in which to evaluate this tool.

(default: 0)

``executable``

Either just the name of the executable or its pathname.

.. container:: windows

On Windows, the path can use environment variables with ${ProgramFiles}

syntax.

(default: the tool name)

``args``

The arguments to pass to the tool executable. You can refer to the

files being merged as well as the output file through these

variables: ``$base``, ``$local``, ``$other``, ``$output``.

The meaning of ``$local`` and ``$other`` can vary depending on which action is

being performed. During an update or merge, ``$local`` represents the original

state of the file, while ``$other`` represents the commit you are updating to or

the commit you are merging with. During a rebase, ``$local`` represents the

destination of the rebase, and ``$other`` represents the commit being rebased.

Some operations define custom labels to assist with identifying the revisions,

accessible via ``$labellocal``, ``$labelother``, and ``$labelbase``. If custom

labels are not available, these will be ``local``, ``other``, and ``base``,

respectively.

(default: ``$local $base $other``)

``premerge``

Attempt to run internal non-interactive 3-way merge tool before

launching external tool. Options are ``true``, ``false``, ``keep`` or

``keep-merge3``. The ``keep`` option will leave markers in the file if the

premerge fails. The ``keep-merge3`` will do the same but include information

about the base of the merge in the marker (see internal :merge3 in

:hg:`help merge-tools`).

(default: True)

``binary``

This tool can merge binary files. (default: False, unless tool

was selected by file pattern match)

``symlink``

This tool can merge symlinks. (default: False)

``check``

A list of merge success-checking options:

``changed``

Ask whether merge was successful when the merged file shows no changes.

``conflicts``

Check whether there are conflicts even though the tool reported success.

``prompt``

Always prompt for merge success, regardless of success reported by tool.

``fixeol``

Attempt to fix up EOL changes caused by the merge tool.

(default: False)

``gui``

This tool requires a graphical interface to run. (default: False)

``mergemarkers``

Controls whether the labels passed via ``$labellocal``, ``$labelother``, and

``$labelbase`` are ``detailed`` (respecting ``mergemarkertemplate``) or

``basic``. If ``premerge`` is ``keep`` or ``keep-merge3``, the conflict

markers generated during premerge will be ``detailed`` if either this option or

the corresponding option in the ``[ui]`` section is ``detailed``.

(default: ``basic``)

``mergemarkertemplate``

This setting can be used to override ``mergemarkertemplate`` from the ``[ui]``

section on a per-tool basis; this applies to the ``$label``-prefixed variables

and to the conflict markers that are generated if ``premerge`` is ``keep` or

``keep-merge3``. See the corresponding variable in ``[ui]`` for more

information.

.. container:: windows

``regkey``

Windows registry key which describes install location of this

tool. Mercurial will search for this key first under

``HKEY_CURRENT_USER`` and then under ``HKEY_LOCAL_MACHINE``.

(default: None)

``regkeyalt``

An alternate Windows registry key to try if the first key is not

found. The alternate key uses the same ``regname`` and ``regappend``

semantics of the primary key. The most common use for this key

is to search for 32bit applications on 64bit operating systems.

(default: None)

``regname``

Name of value to read from specified registry key.

(default: the unnamed (default) value)

``regappend``

String to append to the value read from the registry, typically

the executable name of the tool.

(default: None)

``pager``

---------

Setting used to control when to paginate and with what external tool. See

:hg:`help pager` for details.

``pager``

Define the external tool used as pager.

If no pager is set, Mercurial uses the environment variable $PAGER.

If neither pager.pager, nor $PAGER is set, a default pager will be

used, typically `less` on Unix and `more` on Windows. Example::

[pager]

pager = less -FRX

``ignore``

List of commands to disable the pager for. Example::

[pager]

ignore = version, help, update

``patch``

---------

Settings used when applying patches, for instance through the 'import'

command or with Mercurial Queues extension.

``eol``

When set to 'strict' patch content and patched files end of lines

are preserved. When set to ``lf`` or ``crlf``, both files end of

lines are ignored when patching and the result line endings are

normalized to either LF (Unix) or CRLF (Windows). When set to

``auto``, end of lines are again ignored while patching but line

endings in patched files are normalized to their original setting

on a per-file basis. If target file does not exist or has no end

of line, patch line endings are preserved.

(default: strict)

``fuzz``

The number of lines of 'fuzz' to allow when applying patches. This

controls how much context the patcher is allowed to ignore when

trying to apply a patch.

(default: 2)

``paths``

---------

Assigns symbolic names and behavior to repositories.

Options are symbolic names defining the URL or directory that is the

location of the repository. Example::

[paths]

my_server = https://example.com/my_repo

local_path = /home/me/repo

These symbolic names can be used from the command line. To pull

from ``my_server``: :hg:`pull my_server`. To push to ``local_path``:

:hg:`push local_path`.

Options containing colons (``:``) denote sub-options that can influence

behavior for that specific path. Example::

[paths]

my_server = https://example.com/my_path

my_server:pushurl = ssh://example.com/my_path

The following sub-options can be defined:

``pushurl``

The URL to use for push operations. If not defined, the location

defined by the path's main entry is used.

``pushrev``

A revset defining which revisions to push by default.

When :hg:`push` is executed without a ``-r`` argument, the revset

defined by this sub-option is evaluated to determine what to push.

For example, a value of ``.`` will push the working directory's

revision by default.

Revsets specifying bookmarks will not result in the bookmark being

pushed.

The following special named paths exist:

``default``

The URL or directory to use when no source or remote is specified.

:hg:`clone` will automatically define this path to the location the

repository was cloned from.

``default-push``

(deprecated) The URL or directory for the default :hg:`push` location.

``default:pushurl`` should be used instead.

``phases``

----------

Specifies default handling of phases. See :hg:`help phases` for more

information about working with phases.

``publish``

Controls draft phase behavior when working as a server. When true,

pushed changesets are set to public in both client and server and

pulled or cloned changesets are set to public in the client.

(default: True)

``new-commit``

Phase of newly-created commits.

(default: draft)

``checksubrepos``

Check the phase of the current revision of each subrepository. Allowed

values are "ignore", "follow" and "abort". For settings other than

"ignore", the phase of the current revision of each subrepository is

checked before committing the parent repository. If any of those phases is

greater than the phase of the parent repository (e.g. if a subrepo is in a

"secret" phase while the parent repo is in "draft" phase), the commit is

either aborted (if checksubrepos is set to "abort") or the higher phase is

used for the parent repository commit (if set to "follow").

(default: follow)

``profiling``

-------------

Specifies profiling type, format, and file output. Two profilers are

supported: an instrumenting profiler (named ``ls``), and a sampling

profiler (named ``stat``).

In this section description, 'profiling data' stands for the raw data

collected during profiling, while 'profiling report' stands for a

statistical text report generated from the profiling data.

``enabled``

Enable the profiler.

(default: false)

This is equivalent to passing ``--profile`` on the command line.

``type``

The type of profiler to use.

(default: stat)

``ls``

Use Python's built-in instrumenting profiler. This profiler

works on all platforms, but each line number it reports is the

first line of a function. This restriction makes it difficult to

identify the expensive parts of a non-trivial function.

``stat``

Use a statistical profiler, statprof. This profiler is most

useful for profiling commands that run for longer than about 0.1

seconds.

``format``

Profiling format. Specific to the ``ls`` instrumenting profiler.

(default: text)

``text``

Generate a profiling report. When saving to a file, it should be

noted that only the report is saved, and the profiling data is

not kept.

``kcachegrind``

Format profiling data for kcachegrind use: when saving to a

file, the generated file can directly be loaded into

kcachegrind.

``statformat``

Profiling format for the ``stat`` profiler.

(default: hotpath)

``hotpath``

Show a tree-based display containing the hot path of execution (where

most time was spent).

``bymethod``

Show a table of methods ordered by how frequently they are active.

``byline``

Show a table of lines in files ordered by how frequently they are active.

``json``

Render profiling data as JSON.

``frequency``

Sampling frequency. Specific to the ``stat`` sampling profiler.

(default: 1000)

``output``

File path where profiling data or report should be saved. If the

file exists, it is replaced. (default: None, data is printed on

stderr)

``sort``

Sort field. Specific to the ``ls`` instrumenting profiler.

One of ``callcount``, ``reccallcount``, ``totaltime`` and

``inlinetime``.

(default: inlinetime)

``time-track``

Control if the stat profiler track ``cpu`` or ``real`` time.

(default: ``cpu``)

``limit``

Number of lines to show. Specific to the ``ls`` instrumenting profiler.

(default: 30)

``nested``

Show at most this number of lines of drill-down info after each main entry.

This can help explain the difference between Total and Inline.

Specific to the ``ls`` instrumenting profiler.

(default: 0)

``showmin``

Minimum fraction of samples an entry must have for it to be displayed.

Can be specified as a float between ``0.0`` and ``1.0`` or can have a

``%`` afterwards to allow values up to ``100``. e.g. ``5%``.

Only used by the ``stat`` profiler.

For the ``hotpath`` format, default is ``0.05``.

For the ``chrome`` format, default is ``0.005``.

The option is unused on other formats.

``showmax``

Maximum fraction of samples an entry can have before it is ignored in

display. Values format is the same as ``showmin``.

Only used by the ``stat`` profiler.

For the ``chrome`` format, default is ``0.999``.

The option is unused on other formats.

``progress``

------------

Mercurial commands can draw progress bars that are as informative as

possible. Some progress bars only offer indeterminate information, while others

have a definite end point.

``delay``

Number of seconds (float) before showing the progress bar. (default: 3)

``changedelay``

Minimum delay before showing a new topic. When set to less than 3 * refresh,

that value will be used instead. (default: 1)

``estimateinterval``

Maximum sampling interval in seconds for speed and estimated time

calculation. (default: 60)

``refresh``

Time in seconds between refreshes of the progress bar. (default: 0.1)

``format``

Format of the progress bar.

Valid entries for the format field are ``topic``, ``bar``, ``number``,

``unit``, ``estimate``, ``speed``, and ``item``. ``item`` defaults to the

last 20 characters of the item, but this can be changed by adding either

``-<num>`` which would take the last num characters, or ``+<num>`` for the

first num characters.

(default: topic bar number estimate)

``width``

If set, the maximum width of the progress information (that is, min(width,

term width) will be used).

``clear-complete``

Clear the progress bar after it's done. (default: True)

``disable``

If true, don't show a progress bar.

``assume-tty``

If true, ALWAYS show a progress bar, unless disable is given.

``rebase``

----------

``evolution.allowdivergence``

Default to False, when True allow creating divergence when performing

rebase of obsolete changesets.

``revsetalias``

---------------

Alias definitions for revsets. See :hg:`help revsets` for details.

``server``

----------

Controls generic server settings.

``bookmarks-pushkey-compat``

Trigger pushkey hook when being pushed bookmark updates. This config exist

for compatibility purpose (default to True)

If you use ``pushkey`` and ``pre-pushkey`` hooks to control bookmark

movement we recommend you migrate them to ``txnclose-bookmark`` and

``pretxnclose-bookmark``.

``compressionengines``

List of compression engines and their relative priority to advertise

to clients.

The order of compression engines determines their priority, the first

having the highest priority. If a compression engine is not listed

here, it won't be advertised to clients.

If not set (the default), built-in defaults are used. Run

:hg:`debuginstall` to list available compression engines and their

default wire protocol priority.

Older Mercurial clients only support zlib compression and this setting

has no effect for legacy clients.

``uncompressed``

Whether to allow clients to clone a repository using the

uncompressed streaming protocol. This transfers about 40% more

data than a regular clone, but uses less memory and CPU on both

server and client. Over a LAN (100 Mbps or better) or a very fast

WAN, an uncompressed streaming clone is a lot faster (~10x) than a

regular clone. Over most WAN connections (anything slower than

about 6 Mbps), uncompressed streaming is slower, because of the

extra data transfer overhead. This mode will also temporarily hold

the write lock while determining what data to transfer.

(default: True)

``uncompressedallowsecret``

Whether to allow stream clones when the repository contains secret

changesets. (default: False)

``preferuncompressed``

When set, clients will try to use the uncompressed streaming

protocol. (default: False)

``disablefullbundle``

When set, servers will refuse attempts to do pull-based clones.

If this option is set, ``preferuncompressed`` and/or clone bundles

are highly recommended. Partial clones will still be allowed.

(default: False)

``streamunbundle``

When set, servers will apply data sent from the client directly,

otherwise it will be written to a temporary file first. This option

effectively prevents concurrent pushes.

``pullbundle``

When set, the server will check pullbundle.manifest for bundles

covering the requested heads and common nodes. The first matching

entry will be streamed to the client.

For HTTP transport, the stream will still use zlib compression

for older clients.

``concurrent-push-mode``

Level of allowed race condition between two pushing clients.

- 'strict': push is abort if another client touched the repository

while the push was preparing. (default)

- 'check-related': push is only aborted if it affects head that got also

affected while the push was preparing.

This requires compatible client (version 4.3 and later). Old client will

use 'strict'.

``validate``

Whether to validate the completeness of pushed changesets by

checking that all new file revisions specified in manifests are

present. (default: False)

``maxhttpheaderlen``

Instruct HTTP clients not to send request headers longer than this

many bytes. (default: 1024)

``bundle1``

Whether to allow clients to push and pull using the legacy bundle1

exchange format. (default: True)

``bundle1gd``

Like ``bundle1`` but only used if the repository is using the

*generaldelta* storage format. (default: True)

``bundle1.push``

Whether to allow clients to push using the legacy bundle1 exchange

format. (default: True)

``bundle1gd.push``

Like ``bundle1.push`` but only used if the repository is using the

*generaldelta* storage format. (default: True)

``bundle1.pull``

Whether to allow clients to pull using the legacy bundle1 exchange

format. (default: True)

``bundle1gd.pull``

Like ``bundle1.pull`` but only used if the repository is using the

*generaldelta* storage format. (default: True)

Large repositories using the *generaldelta* storage format should

consider setting this option because converting *generaldelta*

repositories to the exchange format required by the bundle1 data

format can consume a lot of CPU.

``zliblevel``

Integer between ``-1`` and ``9`` that controls the zlib compression level

for wire protocol commands that send zlib compressed output (notably the

commands that send repository history data).

The default (``-1``) uses the default zlib compression level, which is

likely equivalent to ``6``. ``0`` means no compression. ``9`` means

maximum compression.

Setting this option allows server operators to make trade-offs between

bandwidth and CPU used. Lowering the compression lowers CPU utilization

but sends more bytes to clients.

This option only impacts the HTTP server.

``zstdlevel``

Integer between ``1`` and ``22`` that controls the zstd compression level

for wire protocol commands. ``1`` is the minimal amount of compression and

``22`` is the highest amount of compression.

The default (``3``) should be significantly faster than zlib while likely

delivering better compression ratios.

This option only impacts the HTTP server.
