Description:

plone.recipe.zope2instance 7.0.0

Introduction

This recipe creates and configures a Zope instance in parts.
(Despite its name it nowadays only works for Zope 4+.) It also
installs a control script, which is like zopectl, in the bin/ directory.
The name of the control script is the name of the part in buildout.
By default various runtime and log information will be stored inside the var/
directory.
You can use it with a part like this:
[instance]
recipe = plone.recipe.zope2instance
user = admin:admin
http-address = 8080
eggs = my.distribution
zcml = my.distribution

Attention!
This release is targeted at Plone 5.2, ZODB 5, Zope 4 and Zope 5, and
Python 2.7 and 3.5-3.9. If you are using this recipe with earlier versions,
you should use one of the releases from the 4.x series.

Options

Common options

eggs
The list of distributions you want to make available to the instance.

zcml
Install ZCML slugs for the distributions listed, separated by whitespace. You
can specify the type of slug by appending ‘-’ and the type of slug you want
to create. Some examples: my.distribution my.distribution-meta.

http-address
Set the address of the HTTP server.
Can be either a port or a socket address.
Defaults to 0.0.0.0:8080.

ip-address
The default IP address on which Zope’s various server protocol
implementations will listen for requests. If this is unset, Zope will listen
on all IP addresses supported by the machine. This directive can be
overridden on a per-server basis in the servers section. Defaults to not
setting an ip-address. Used for ZServer only, not WSGI.

threads
Specify the number of worker threads used to service requests.
The default is 4 for WSGI (since this is the waitress default) and 2 for ZServer.

zodb-cache-size
Set the ZODB cache size, i.e. the number of objects which the ZODB cache
will try to hold. Defaults to 30000.

zserver-threads
Deprecated, use threads instead.
Specify the number of threads that Zope’s ZServer web server will use to
service requests. The recipes default is 2. Used for ZServer only, not WSGI.

environment-vars
Define arbitrary key-value pairs for use as environment variables during
Zope’s run cycle. Example:
environment-vars =
TZ US/Eastern
zope_i18n_allowed_languages en
zope_i18n_compile_mo_files true

initialization
Specify some Python initialization code to include within the generated
sitecustomize.py script (Buildout >= 1.5) or within the instance script
(Buildout < 1.5). This is very limited. In particular, be aware that leading
whitespace is stripped from the code given. added in version 4.2.14

wsgi
By default this recipe creates a Python script that uses waitress as a
WSGI server. When running Python 2 you can disable WSGI and use ZServer by
setting wsgi = off and including ZServer in the eggs specification
list. Example:
wsgi = off
eggs =
...
ZServer
You can use other PasteDeploy-compatible WSGI servers by passing a path
to a WSGI configuration file here and including the WSGI server’s egg in the
eggs specification. Example:
wsgi = ${buildout:directory}/etc/gunicorn.ini
eggs =
...
gunicorn
The WSGI configuration file will not be created for you in this case,
unlike the built-in waitress support. You have to provide it yourself.

max-request-body-size
Specify the maximum request body size in bytes
The default is 1073741824 (since this is the waitress default)

Theme resources
Please refer to https://pypi.org/project/plone.resource for more
details and setup instructions.

resources
Specify a central resource directory. Example:
resources = ${buildout:directory}/resources

Locales

locales
Specify a locales directory. Example:
locales = ${buildout:directory}/locales

This registers a locales directory with extra or different translations.
If you want to override a few translations from the plone domain in the
English language, you can add a en/LC_MESSAGES/plone.po file in this
directory, with standard headers at the top, followed by something like
this:
#. Default: "You are here:"
msgid "you_are_here"
msgstr "You are very welcome here:"
Translations for other message ids are not affected and will continue
to work.

Development options

verbose-security
Set to on to turn on verbose security (and switch to the Python security
implementation). Defaults to off (and the C security implementation).

debug-exceptions
WSGI only: set to on to disable exception views including
standard_error_message. Exceptions other than Unauthorized or
ConflictError can then travel up into the WSGI stack. Use this option
if you want more convenient error debugging offered by WSGI middleware
such as the werkzeug debugger. See the Zope
WSGI documentation for
examples.

profile
Set to on enables repoze.profile.
Defaults to off,
If switched on there are further options prefixed with profile_ to configure it as below.
You will need to add the repoze.profile package, either by adding it to your eggs section directly or by using the extra plone.recipe.zope2instance[profile].

profile_log_filename
Filename of the raw profile data.
Default to profile-SECTIONNAME.raw.
This file contains the raw profile data for further analysis.

profile_cachegrind_filename
If the package pyprof2calltree is installed, another file is written.
It is meant for consumation with any cachegrind compatible application.
Defaults to cachegrind.out.SECTIONNAME.

profile_discard_first_request
Defaults to true.
See repoze.profile docs for details.

profile_path
Defaults to /__profile__.
The path for through the web access to the last profiled request.

profile_flush_at_shutdown
Defaults to true.
See repoze.profile docs for details.

profile_unwind
Defaults to false.
See repoze.profile docs for details.

Direct storage
If you have only one application process, it can open the database files
directly without running a database server process.

file-storage
The filename where the ZODB data file will be stored.
Defaults to ${buildout:directory}/var/filestorage/Data.fs.

blob-storage
The name of the directory where the ZODB blob data will be stored, defaults
to ${buildout:directory}/var/blobstorage.

Basic ZEO storage
If you want multiple application processes you need to run a separate
database server process and connect to it, either via ZEO or RelStorage.

zeo-address
Set the address of the ZEO server. Defaults to 8100. You can set
more than one address (white space delimited). Alternative addresses will
be used if the primary address is down.

zeo-client
Set to ‘on’ to make this instance a ZEO client. In this case, setting the
zeo-address option is required, and the file-storage option has no effect.
To set up a ZEO server, you can use the plone.recipe.zeoserver recipe.
Defaults to ‘off’.

blob-storage
The location of the blob zeocache, defaults to var/blobcache. If
shared-blob is on it defaults to ${buildout:directory}/var/blobstorage.

shared-blob
Defaults to off. Set this to on if the ZEO server and the instance have
access to the same directory. Either by being on the same physical machine or
by virtue of a network file system like NFS. Make sure this instances
blob-storage is set to the same directory used for the ZEO servers
blob-storage. In this case the instance will not stream the blob file
through the ZEO connection, but just send the information of the file
location to the ZEO server, resulting in faster execution and less memory
overhead.

zeo-client-read-only-fallback
A flag indicating whether a read-only remote storage should be acceptable as
a fallback when no writable storages are available. Defaults to false.

read-only
Set zeo client as read only added in version 4.2.12

ZEO authentication
You need to activate ZEO auth on the server side as well, for this to work.
Without this anyone that can connect to the database servers socket can read
and write arbitrary data.

zeo-username
Enable ZEO authentication and use the given username when accessing the
ZEO server. It is obligatory to also specify a zeo-password.

zeo-password
Password to use when connecting to a ZEO server with authentication
enabled.

zeo-realm
Authentication realm to use when authentication with a ZEO server. Defaults
to ‘ZEO’.

RelStorage
Please refer to https://pypi.org/project/RelStorage for more details
and setup instructions.

rel-storage
Allows to set a RelStorage instead of a FileStorage.
Contains settings separated by newlines, with these values:

type: any database type supported (postgresql, oracle, mysql)
RelStorage specific keys, like cache-servers and poll-interval
all other keys are passed on to the database-specific RelStorage adapter.

Example:
rel-storage =
type oracle
dsn (DESCRIPTION=(ADDRESS=(HOST=s01))(CONNECT_DATA=(SERVICE_NAME=d01)))
user tarek
password secret

Logging
In most cases you don’t need to adjust any of this, you might want to adjust
log levels or configure mailinglogger.

event-log
The filename of the event log. Defaults to buildout:directory/var/log/{partname}.log
Setting this value to ‘disable’ will make the <eventlog> section to be omitted,
disabling logging events by default to a .log file.

event-log-level
Set the level of the console output for the event log. Level may be any of
CRITICAL, ERROR, WARN, INFO, DEBUG, or ALL. Defaults to INFO.

event-log-max-size
Maximum size of event log file. Enables log rotation.
Used for ZServer only, not WSGI.

event-log-old-files
Number of previous log files to retain when log rotation is enabled.
Defaults to 1. Used for ZServer only, not WSGI.

event-log-custom
A custom section for the eventlog, to be able to use another
event logger than logfile. Used for ZServer only, not WSGI.

mailinglogger
A mailinglogger section added into the event log.
Used for ZServer only, not WSGI. Example snippet:
<mailing-logger>
level error
flood-level 10
smtp-server smtp.mydomain.com
from logger@mydomain.com
to errors@mydomain.com
subject [My domain error] [%(hostname)s] %(line)s
</mailing-logger>
You will need to add mailinglogger to your buildout’s egg section to make this work.

access-log, z2-log
The filename for the Z2 access log. Defaults to var/log/partname−Z2.log(var/log/{partname}-access.log) for WSGI).
You can disable access logging by setting this value to ‘disable’.
For ZServer this will omit the <logger access> section in zope.conf.
For WSGI, the logging handler will be a NullHandler.

access-log-level, z2-log-level
Set the log level for the access log. Level may be any of CRITICAL, ERROR,
WARN, INFO, DEBUG, or ALL. Defaults to WARN (INFO for WSGI).

access-log-max-size
Maximum size of access log file. Enables log rotation.
Used for ZServer only, not WSGI.

access-log-old-files
Number of previous log files to retain when log rotation is enabled.
Defaults to 1. Used for ZServer only, not WSGI.

access-log-custom
Like event-log-custom, a custom section for the access logger, to be able
to use another event logger than logfile. Used for ZServer only, not WSGI.

sentry_dsn
Provide a Sentry DSN here to enable basic Sentry logging documented
in https://docs.sentry.io/platforms/python/logging/. You will need to add the
Python Sentry SDK, either by adding it to your eggs section directly or by adding
plone.recipe.zope2instance[sentry].
Available for WSGI only.

sentry_level
Set the logging level for Sentry breadcrumbs.
Available for WSGI only.

sentry_event_level
Set the logging level for Sentry events.
Available for WSGI only.

sentry_ignore
Set the (space separated list of) logger names that are ignored by Sentry.
Available for WSGI only.

sentry_max_value_length
Set the maximum size of traceback messages sent to Sentry. If your tracebacks
get truncated, increase this above the sentry-sdk default of 1024.
Available for WSGI only.

Advanced logging options for WSGI
For more complex logging configuration, the zope2instance recipe exposes the
underlaying logging.handlers functionality through the access-log-handler
and event-log-handler configuration options. This allows you to configure an
arbitrary logging handler for Python as defined in
here.
The supplementary options event-log-args, event-log-kwargs and
access-log-args, access-log-kwargs can be used for passing positional and
keyword arguments to the constructor of the underlaying handler.

access-log-handler
The (dotted) name of an importable Python logging handler like
logging.handlers.RotatingFileHandler.
Default: FileHandler

access-log-args
A python tuple which usually refers to the logging filename and opening mode
of the file like (“access.log”, “a”). Note that you a Python tuple with
only one element (e.g. only the filename) must have a trailing comma like
(“access.log”, ) The access-log-args is used to specify the positional
parameters for the logging handler configured through access-log-handler.
Default: (r”access.log”, “a”)

access-log-kwargs
A python dictionary used for passing keyword argument for the logging handler
configured through access-log-handler e.g. {“when”: “h”, “interval”: 1}.
Default: {}

event-log-handler
Same as access-log-handler but for the configuration of the event log of Plone.

event-log-args
Same as access-log-args but for the configuration of the event log of Plone.

event-log-kwargs
Same as access-log-kwargs but for the configuration of the event log of Plone.

Example (access log rotation based on file size)
This example uses a RotatingFileHandler https://docs.python.org/3/library/logging.handlers.html#rotatingfilehandler
which rotates the access log when it becomes larger than 10 MB while keeping seven copies:
access-log-handler = logging.handlers.RotatingFileHandler
access-log-args = (r"access.log", "a")
access-log-kwargs = {"maxBytes": 10000000, "backupCount": 7}

Example (rotating of event log after each day)
This example uses a TimedRotatingFileHandler https://docs.python.org/3/library/logging.handlers.html#timedrotatingfilehandler
for rotating the event log every 24 hours or one day:
event-log-handler = logging.handlers.TimedRotatingFileHandler
event-log-args = (r"event.log", )
event-log-kwargs = {"when": "D", "interval": 1}

Load non-setuptools compatible Python libraries

products
A list of paths where Zope 2 products are installed. The first path takes
precedence in case the same product is found in more than one directory.
Zope 2 products are deprecated and won’t work any longer in a future version
of Zope/Plone.

extra-paths
A list of paths where additional Python packages are installed. The paths
are searched in the given order after all egg and products paths.

Advanced ZCML options

site-zcml
If you want a custom site.zcml file, put its content here. If this option
is used the zcml and zcml-additional options are ignored.

zcml-additional
Extra ZCML statements that should be included in the generated site.zcml
file.

Advanced ZEO options

zeo-client-cache-size
Set the size of the ZEO client cache. Defaults to ‘128MB’. The ZEO cache is
a disk based cache shared between application threads. It is stored either in
temporary files or, in case you activate persistent cache files with the
option client (see below), in the folder designated by the zeo-var
option.

zeo-client-client
Set the persistent cache name that is used to construct the cache
filenames. This enables the ZEO cache to persist across application restarts.
Persistent cache files are disabled by default.

zeo-client-blob-cache-size
Set the maximum size of the ZEO blob cache, in bytes. If not set, then
the cache size isn’t checked and the blob directory will grow without bound.

zeo-client-blob-cache-size-check
Set the ZEO check size as percent of zeo-client-blob-cache-size (for
example, 10 for 10%). The ZEO cache size will be checked when this many
bytes have been loaded into the cache. Defaults to 10% of the blob cache
size. This option is ignored if shared-blob is enabled.

zeo-client-drop-cache-rather-verify
Indicates that the cache should be dropped rather than verified when
the verification optimization is not available (e.g. when the ZEO server
restarted). Defaults to ‘False’.

zeo-storage
Set the storage number of the ZEO storage. Defaults to ‘1’.

zeo-var
Used in the ZEO storage snippets to configure the ZEO var folder, which
is used to store persistent ZEO client cache files. Defaults to the system
temporary folder.

Advanced options

wsgi-ini-template
By default plone.recipe.zope2instances uses a hard-coded template for the
generated WSGI configuration in parts/<partname>/etc/wsgi.ini. The template
is defined as wsgi_ini_template variable within the recipe.py
file.
You can override the template with a custom template file using this option.
Example:
wsgi-ini-template = /path/to/wsgi_template.ini
The available variables for variable substition can be found within the existing template (see above).

asyncore-use-poll
By default false. If you want the waitress.asyncore.loop flag to use poll()
instead of the default select() set to true.

before-storage
Wraps the base storage in a “before storage” which sets it in
read-only mode from the time given (or “now” for the current time).
This option is normally used together with demo-storage for a
normally running site in order for changes to be made to the
database.

client-home
Sets the clienthome for the generated instance.
Defaults to ${buildout:directory}/var/<name of the section>.

clear-untrusted-proxy-headers
This tells Waitress to remove any untrusted proxy headers
(“Forwarded”, “X-Forwarded-For”, “X-Forwarded-By”,
“X-Forwarded-Host”, “X-Forwarded-Port”, “X-Forwarded-Proto”).
The default in waitress 1 is false, but waitress 2 changes this to true.
We explicitly default to false.
When you set it to true, you may need to set other wsgi.ini options like
trusted_proxy_headers and trusted_proxy.
Setting those is not supported by the recipe yet.
Used for WSGI only, not ZServer.

default-zpublisher-encoding
This controls what character set is used to encode unicode data that reaches
ZPublisher without any other specified encoding. This defaults to ‘utf-8’.
Plone requires this to be set to utf-8.

demo-storage
If ‘on’ it enables the demo storage. By default, this is a
memory-based storage option; changes are not persisted (see the
demo-file-storage option to use a persistent storage for changes
made during the demonstration).
To use with a base storage option configured with a blob-storage,
you must set a demo-blob-storage.

demo-file-storage
If provided, the filename where the ZODB data file for changes
committed during a demonstration will be stored.

demo-blob-storage
If provided, the name of the directory where demonstration ZODB blob
data will be stored.
This storage may be connected to a demonstration file storage, or
used with the default memory-based demo storage (in this case you
might want to use a temporary directory).

storage-wrapper
Template for arbitrary configuration to be wrapped around the main storage.
%s will be replaced with the existing storage configuration.

effective-user
The name of the effective user for the Zope process. Defaults to not setting
an effective user.

enable-product-installation
Enable the persistent product registry by setting this to on. By default
the registry is turned off. Enabling the registry is deprecated.

ftp-address
Give a port for the FTP server. This enables the FTP server.
Used for ZServer only, not WSGI.

http-force-connection-close
Set to on to enforce Zope to set Connection: close header.
This is useful if for example a 304 leaves the connection open with
Varnish in front and Varnish tries to reuse the connection.

http-fast-listen
Set to off to defer opening of the HTTP socket until the end of the Zope
startup phase. Defaults to on.

icp-address
Give a port for the ICP server. This enables the ICP server.
Used for ZServer only, not WSGI.

import-directory
Used to configure the import directory for instance.
Defaults to <client-home>/import.

port-base
Offset applied to the port numbers used for ZServer configurations. For
example, if the http-server port is 8080 and the port-base is 1000, the HTTP
server will listen on port 9080. This makes it easy to change the complete
set of ports used by a Zope server process. Zope defaults to 0.

python-check-interval
An integer telling the Python interpreter to check for asynchronous events
every number of instructions. This affects how often thread switches occur.
Defaults to 1000.

relative-paths
Set this to true to make the generated scripts use relative
paths. You can also enable this in the [buildout] section.

scripts
Add this parameter with no arguments to suppress script generation.
Otherwise (i.e. without this parameter), scripts for packages added
to the eggs parameter will be generated. You may also configure
per package. E.g.:
[instance]
recipe = plone.recipe.zope2instance
eggs =
Plone
mr.migrator
my.package
scripts = my_package_script
In the above example, only my_package_script will be generated. Keep in
mind that the egg containing the script (my.package in the example) must
be listed explicitly in the eggs option, even if it is a dependency of an
already listed egg.

template-cache
Used to configure the cache for page-template files. Chameleon will write
compile page-templates into this directory and use it as a cache.
See https://chameleon.readthedocs.io/en/latest/configuration.html for more info.
Valid options are off or on or a directory-location.
Defaults to ${buildout:directory}/var/cache (it also confirms to what var is set to).

var
Used to configure the base directory for all things going into var.
Defaults to ${buildout:directory}/var.

webdav-address
Give a port for the WebDAV server. This enables the WebDAV server.
Used for ZServer only, not WSGI.

webdav-force-connection-close
Valid options are off and on. Defaults to off.
Used for ZServer only, not WSGI.

pipeline
The main application pipeline served by the wsgi server.
By default the pipeline is:
translogger
egg:Zope#httpexceptions
zope
The translogger line in the pipeline will be removed
if z2-log is set to disabled or if it is not set
and access-log is set to disabled (case insensitive).
Used for WSGI only, not ZServer.

zlib-storage
Adds support for file compression on a file storage database. The
option accepts the values ‘active’ (compress new records) or
‘passive’ (do not compress new records). Both options support
already compressed records.
You can use the ‘passive’ setting while you prepare a number of
connected clients for compressed records.

zodb-cache-size-bytes
Set the ZODB cache sizes in bytes. This feature is still experimental.

zodb-temporary-storage
If given Zope’s default temporary storage definition will be replaced by
the lines of this parameter. If set to “off” or “false”, no temporary storage
definition will be created. This prevents startup issues for basic Zope 4
sites as it does not ship with the required packages by default anymore.

zope-conf
A relative or absolute path to a zope.conf file. If this is given, many of
the options in the recipe will be ignored.

zope-conf-imports
You can define custom sections within zope.conf using the ZConfig API.
But, in order for Zope to understand your custom sections, you’ll have to
import the python packages that define these custom sections using %import
syntax.
Example:
zope-conf-imports =
mailinglogger
eea.graylogger

zope-conf-additional
Give additional lines to zope.conf. Make sure you indent any lines after
the one with the parameter.
Example:
zope-conf-additional =
locale fr_FR
http-realm Slipknot

zopectl-umask
Manually set the umask for the zopectl process.
Example:
zopectl-umask = 002

http-header-max-length
Manually set the maximum size of received HTTP header being processed by Zope.
The request is discarded and considered as a DoS attack if the header size exceeds
this limit. Default: 8192. Used for ZServer only, not WSGI.
Example:
http-header-max-length = 16384

The generated control script

Windows
On the windows platform the bin/instance script as described below will not be generated, because it uses a Unix specific implementation.
To run Plone start it with:
.\bin\runwsgi.exe -v .\parts\etc\wsgi.ini
Or for development in debug mode use:
.\bin\runwsgi.exe -v .\parts\etc\wsgi.ini
The documentation for the extended Zope control script below does not apply.

The debug, console and run commands
The extended Zope control script installed by this recipe, usually
bin/instance by convention, offers a debug command and another
run command. The debug command starts an interactive Python
prompt with the Zope application available via the app name.
Similarly, the run command accepts a Python script as an argument
that will be run under the same conditions.
These commands have also been extended to set up a more complete
environment. Specifically, these commands set up a REQUEST, log in
the AccessControl.SpecialUsers.system user, and may traverse to an
object, such as a CMF portal. This environment set up is controlled
with following options:
-R/--no-request -- do not set up a REQUEST.
-L/--no-login -- do not login the system user.
-O/--object-path <path> -- Traverse to <path> from the app
and make available as `obj`.
Note that these options must come before the script name,
e.g. bin/instance -RLOPlone/front-page debug
The console command is similar to the fg command, but it does not
create a subprocess to start up Zope. This is useful for two
use cases. First, the supervisor program, to supervise long running
processes like a Zope, require the process not to fork away, so that
supervisor can control it.
Second, IDEs like WingIDE and PyCharm support debugging running
processes from within. For this to work, the process should also
not fork away.

Developing your own control script commands
Third-party distributions may add additional commands to the control script by
installing a ‘plone.recipe.zope2instance.ctl’ entry point. For example,
an egg called MyDist could include a module called mymodule with the
following custom command:
def foo(self, *args)
"""Help message here"""
print 'foo'
It would then install the foo method as a command for the control script using
the following entry point configuration in setup.py:
entry_points="""
[plone.recipe.zope2instance.ctl]
foo = mymodule:foo
"""
This would allow invoking the foo method by running bin/instance foo
(assuming the instance control script was installed by a buildout part
called instance.) The entry point is invoked with the following
parameters:

self
An instance of plone.recipe.zope2instance.ctl.AdjustedZopeCmd.

args
Any additional arguments that were passed on the command line.

Known issues

the restart command will not function reliably if you run the buildout
while the Zope instance is still running. In those cases, always use
stop followed by start to restart the Zope instance.

The way zopectl and this recipe handle commands
is totally different.
[gforcada]

4.2.19 (2016-02-15)
New:

Handle commands registered for zopectl as well.
Up to now they were handled but not displayed at all
(i.e. in help and descriptions).
https://github.com/plone/plone.recipe.zope2instance/issues/18
[gforcada]

4.2.18 (2015-07-27)

Allow to disable logs. Set z2-log to the value disable to
disable the Z2 access log. Set event-log to the value
disable to disable the event log.
[frapell]

4.2.17 (2015-04-29)

Added zope-conf-imports option to easily import ZConfig components
within zope.conf using %import syntax.

be able to set zeo client as read only from buildout configuration
[vangheem]

4.2.11 (2013-05-23)

When creating the blobstorage dir, make it only readable for the
current user, otherwise you get a ZODB warning on startup. This
uses code from the ZODB, which does the same when Zope starts up and
the blobstorage directory does not exist yet.
[maurits]
Fixed check for empty custom_access_event_log and custom_event_log.
[alecghica]

4.2.10 (2013-03-05)

Added event and access log rotation capability.
[sureshvv]

4.2.4 (2012-08-29)

Expose ‘drop-cache-rather-verify’ ZEO client option which indicates that
the cache should be dropped rather than verified when the verification
optimization is not available (e.g. when the ZEO server restarted).
[runyaga]
Strip all empty lines out of zeo.conf to provide more compact view.
[runyaga]

4.2.3 (2012-08-04)

Fix zcml load order of the optional locales directory. Translation overrides
need to be loaded first.
[sunew]

4.2.2 (2012-07-02)

Changed client connection cache defaults. We specify a cache size of 30000
instead of 10000.
[hvelarde]
Add new locales option for specifying a locales directory with
extra or different translations.
[maurits]

4.2.1 (2012-04-15)

Add support for a changes storage for demo storage (in addition to
the base storage). Local file and blob storage is supported.
[malthe]
Add support for before storage (via the zc.beforestorage package).
[malthe]
Make script suppression optional (via empty scripts parameter). Otherwise,
scripts for packages listed in eggs parameter will be generated.
[aclark]
Support all RelStorage options, even future options. Used a simple pattern
to recognize where options should be placed: any option name containing a
dash is a generic option; the rest (except “name”) are database-specific.
[hathawsh]

4.1.9 - 2011-08-11

No longer rely on softwarehome in startup script.
[hannosch]

4.1.8 - 2011-07-17

Add preliminary support for Zope 4.0, by re-using the skeleton for 2.13.
[hannosch]
Added zeo-client-blob-cache-size and zeo-client-blob-cache-size-check
options to control maximum size of blob cache, and when to check the size,
when using ClientStorage without shared blobs.
[davidjb]
If a resource directory is specified using resources, create it if it does
not yet exist.
[davisagli]
Support the new create-schema option introduced in RelStorage 1.5.0b2.
[mj]

4.1.7 - 2011-06-07

Renamed the optional 998-resources.zcml (introduced in 4.1.6) to
998-resources-configure.zcml, otherwise it does not get loaded
in the standard site.zcml.
[maurits]

4.1.6 - 2011-06-01

Add new resources option for specifying a plone.resource central resource
directory.
[elro]

4.1.5 - 2011-02-17

Respect new include-site-packages buildout option introduced in buildout
1.5. Closes https://bugs.launchpad.net/bugs/716360.
[yuppie, hannosch]
Added option import-directory to point to custom import folder.
[garbas]

4.1.4 - 2011-01-01

Removed zeo-client-name option. The option had no effect since ZODB 3.2
and was removed in Zope 2.13. This closes
https://bugs.launchpad.net/bugs/694920.
[hannosch]

4.1.3 - 2010-12-20

Added option http-force-connection-close which was only present in comment.
[tesdal]

4.1.2 - 2010-12-05

Fixed error introduced in 4.1.1.
[hannosch]

4.1.1 - 2010-12-05

Disambiguate the blob-storage option if shared-blob isn’t used. In this
case we use var/blobcache as a default location, so we don’t accidentally
overwrite the real blob data with a blob zeocache. Refs
https://bugs.launchpad.net/bugs/645904.
[hannosch]

4.1 - 2010-12-04

Give the readme an overhaul, group options into sections and mention the
most commonly used ones at the top.
[hannosch]
Add some flexibility to site.zcml creation. Thanks to Wolfgang Schnerring
for the patch. This closes
https://bugs.launchpad.net/collective.buildout/+bug/335311.
[hannosch]
Raise an exception if both ZEO and RelStorage are configured at the same
time. This closes https://bugs.launchpad.net/collective.buildout/+bug/645100.
[hannosch]
Added support for zc.buildout 1.5, while retaining support for 1.4. Thanks
to Jeff Rush for the patch. This closes
https://bugs.launchpad.net/collective.buildout/+bug/683584.
[hannosch]

4.0.5 - 2010-10-22

Added support for specifying the new RelStorage options shared-blob-dir,
blob-cache-size, blob-cache-size-check, and blob-chunk-size.
[hathawsh]

4.0.4 - 2010-09-09

Add friendly error message if non-admin tries
“instance install|start|restart|stop|remove”.
[kleist]
Exit with the return code of the executed do_* method. This closes #10906
(clicking “Restart” in ZMI control panel caused shutdown).
[kleist]
Implemented the “restart” command for “bin/instance.exe”.
[kleist]

4.0.3 - 2010-08-20

Setuptools / Subversion ignores empty directories and doesn’t include them
into the source distribution. Added readme files to the bin and var
directories inside the skeleton. This lets persistent ZEO caches work again,
which want to put their files into the var directory.
[hannosch]

4.0.2 - 2010-08-04

Rewritten major parts of commands specific for the Windows Service, inspired
by “collective.buildout.cluster.base.ClusterBase” as used by the Windows
installer. Closes http://dev.plone.org/plone/ticket/10860.
[kleist]

4.0.1 - 2010-07-30

Use pid file to check for running application, instead of service status.
[sidnei]

4.0.0 - 2010-07-21

“console” mode on Windows no longer returns immediately, thus makes it
usable by the Windows Service.
[kleist]
Made tests compatible with Windows.
[hannosch]
Added support for specifying new RelStorage options cache-local-mb,
cache-delta-size-limit, commit-lock-timeout and commit-lock-id.
[hannosch]

4.0b2 - 2010-06-23

Added a new dependency on mailinglogger and expose it as a convenient
new option.
[hannosch]
Removed testing dependency on zope.testing and refactored test setup.
[hannosch]

4.0b1 - 2010-04-04

The recipe could sometimes fail to build twice if no zcml option was given.
This closes http://dev.plone.org/plone/ticket/10296.
[hannosch]

4.0a4 - 2010-02-04

Removed commented out options from the http-server section.
[hannosch]
Added new enable-product-installation option and let it default to off.
[hannosch]

4.0a3 - 2010-01-24

Tried to restore the Windows service functionality, getting closer but not
there yet all the way.
[hannosch]
Use the same quoting approach for the console as for fg command on Windows.
[hannosch]
Don’t call zopectl.quote_command(), since the added outer double quotes caused
subprocess.call() to fail with “WindowsError: [Error 87] The parameter is
incorrect”. Instead, hand roll the quoting (save outer quotes).
[kleist]
Un-hardcoded ‘:’ as path separator, caused “ImportError: No module named
Zope2.Startup” on Windows. See http://dev.plone.org/plone/ticket/9991.
[kleist]
Removed the import directory from the skeleton. You can place import files
into the import directory in the client home in new Zope 2 versions.
[hannosch, davisagli]
Make it possible to omit the user option, in which case buildout will ask
for a user and password, when a new instance is created.
[hannosch]
Use our own make instance script and skeletons, only providing what we
really need anymore.
[hannosch]
Merge the two ZopeCmd classes into one. We don’t rely or generate the runzope
script or anything inside parts/instance/bin anymore.
[hannosch]
By default create a blob-storage in var/blobstorage.
[hannosch]
Removed the no-shell option and made it the default for running the
process. This also removes the need for the runzope script.
[hannosch]
This version can no longer be used to install a non-eggified Zope2. The
zope2-location option was removed.
[hannosch]

4.0a2 - 2009-12-02

Make it possible for third-party packages to add additional commands to the
control script by supplying a ‘plone.recipe.zope2instance.ctl’ entry point.
[davisagli]

4.0a1 - 2009-11-14

Removed the test command support from the control script which lets us
remove quite a bit of hackery. Added a note about using bin/test instead.
[hannosch]
Added an explicit python-check-interval option and change its default to
1000 instead of Python’s own default of 100.
[hannosch]
Changed default zserver-threads to two instead of four.
[hannosch]
Changed client connection cache defaults. We specify a cache size of 10000
instead of 5000. Also changed ZEO client cache to 128MB instead of 30MB.
[hannosch]
If we are used in an environment with Zope2 as an egg, we make sure to
install the mkzopeinstance and runzope scripts we depend on ourselves.
This is done even if they already exist, since the eggs may have changed.
[hannosch, davisagli]
Added Zope2 egg to the list of dependencies of this recipe. This can cause
trouble for Zope versions before Zope 2.12 or Plone before 4.0.
[hannosch]
Added the cache-prefix option for RelStorage.

3.6 (2009-10-11)

Expanded the RelStorage options, including keep-history and replica-conf.
[hathawsh]

3.5 (2009-09-05)

Added support for relative-paths in the script generation.
[jvloothuis]
When zope-conf is set the config file will be directly loaded from that
location (it previously created a stub zope.conf which included it).
[jvloothuis]
Added an option to avoid using the normal shell scripts for starting Zope.
This makes it possible to avoid the hard-coded paths in these scripts.
[jvloothuis]
Allow the blob-dir parameter in RelStorage configurations.
[hathawsh]

3.4 (2009-08-12)

Support in line with fix for LP#407916.
[gotcha]
Changed the ‘mkzopeinstance’ call respect the ‘bin-directory’ option.
[esteele]
Removed the zope2-egg option and the simple startup script from the recipe.
We assume that we have an egg distribution if zope2-location is not set.
[hannosch]
Merged the davisagli-eggified-zope branch into the trunk.
[hannosch]
Add a new icp-address option. This is useful for environments where
e.g. squid is used to front a Zope/ZEO cluster. See
http://www.zope.org/Members/htrd/icp/intro
[neaj]

3.3 - 2009-07-07

Add handling for RelStorage options.
[elro]
Reinstall scripts on update which appears to be good recipe practice.
[stefan]

3.2 - 2009-04-02

Add a new zcml-additional option. This is useful for environments where
non-code configuration (such as database connection details for
ore.contentmirror) are managed through zcml.
[wichert]

3.1 (2009-03-15)

The 2.9 fix for spaces caused a problem using debug (bug 337740)
due to the way do_debug passed the “-i” command line argument
to get_startup_cmd.
[smcmahon]

3.0 (2009-02-27)

The 2.9 fix for the instance run command was itself broken and
would fail on anything except Windows.
[smcmahon]
Changed the zope2-egg option to omit any kind of instance creation for
now. The mkzopeinstance script relies on being able to import Zope2, which
is not available when buildout runs.
[hannosch]

2.9 (2009-02-26)

The instance run command was vulnerable to spaces in pathnames, and
needed some extra quoting for win32.
[smcmahon]
Check for existence of windows scripts before patching them. Some
Linux distributions of Zope2 don’t have these files.
[smcmahon]
Delegate commands to win32serviceutil.HandleCommand() on win32,
instead of starting the interpreter through os.system(). Should
shave off a couple seconds from overall time taken to process those
commands.
[sidnei]
Compute serviceClassString ourselves, since we are calling this
as a module and not directly as __main__, otherwise the service
won’t be installed correctly.
[sidnei]

2.8 (2008-12-05)

Add more tests for ZEO client with blob and demo storages.
Still no test on ‘shared-blob-dir’ option.
[encolpe]
Always use ‘r’-style strings for passing script and configuration
filenames (eg: on ‘instance run <script>’).
[sidnei]
Add a demo-storage option and tests.
[encolpe]
Add a first test for blob-storage.
[encolpe]

2.7 (2008-11-18)

Added a zope2-egg option and an accompanying simple startup script for
use with an eggified Zope2.
[hannosch]
Do not fail with a Zope2 egg checkout.
[hannosch]
Normalize first argument to os.spawnl. It can get really upset
otherwise (dll import failure on a relocatable python install).
[sidnei]
Use same quoting as on ‘do_foreground’ for servicescript
usage. Fixes problems with installing the buildout-based Plone
installer for Windows on a path with spaces.
[sidnei]
Ensure that do_foreground leaves self.options.program arguments as it
found them. This makes it possible to use ‘fg’ and ‘debug’ more than
once within the same control session.
[klm]

2.6 (2008-10-22)

Normalize, absolutize and lowercase-ize (is that a word?) paths
before comparing, to avoid problems with relative filenames and
different drive letter case on Windows.
[sidnei]

2.5 (2008-09-22)

Add support for zodb-cache-size-bytes from ZODB 3.9 and later.
[wichert]

2.4 (2008-07-15)

Introduced zope.conf variables “INSTANCEHOME” and “CLIENTHOME”.
Its very very helpful in cluster setups with zope-conf-additional
sections (buildout lacks to reference the current section).
[jensens]
Made test command compatible with zope.testing 3.6.
[hannosch]

2.3.1 (2008-06-10)

No code changes. Released to fix the 2.3 release which put .egg files in
the wild.
[hannosch]

2.3 (2008-06-06)

Need to actually pass in deprecation-warnings, otherwise we get a
KeyError.
[sidnei]
Fix another place where the directory name needed to be escaped to
avoid problems with spaces.
[sidnei]
Don’t try to delete location if it does not exist.
[sidnei]

2.2 (2008-06-06)

Added deprecation-warnings option that allows turning the option
to disable deprecation warnings on or off. You can provide the value
error to it, and every deprecation warning will be turned into an
exception.
[sidnei]
Fix copy and paste error that caused a failure on changing
runzope.bat to call servicewrapper.py.
[sidnei]
Escape ‘executable’ argument before passing it to os.spawnl, in
order to make it work on Windows when the executable name has spaces
on it.
[sidnei]
Added http-fast-listen option. Use of this option requires Zope >= 2.11.
[stefan]

2.1 (2008-06-05)

Fixed a test problem on Windows, where explicit closing of files is required.
[hannosch]
Call servicewrapper.py from runzope.bat instead of setting
PYTHONPATH and calling Zope2/Startup/run.py. That way we set
sys.path from inside Python code and avoid exceeding the maximum
environment variable limit.
[sidnei]
Allow to use an alternative temporary storage, by specifying the new
zodb-temporary-storage option.
[jensens]
Added environment-vars option to set environment variables. Changed
the zope-conf-additional example code to something that isn’t covered by
the recipe.
[claytron]

2.0 (2008-05-29)

Do not use system but exec when starting Zope. This makes it possible for
process management tools to properly manage Zope processes.
[wichert]
Added site-zcml option
Added tests
[mustapha]
Add support for ZEO authentication. Note that this does not work with any
released Zope or ZODB version at this moment. See
http://mail.zope.org/pipermail/zope/2005-October/161951.html for required
patches.
[wichert]
Added FTP and WebDAV options
[claytron]
Allow rel-storage to be an empty string, meaning ‘do not use relstorage’.
This allows an extending buildout configuration to disable relstorage again.
[mj]

1.9 (2008-04-15)

Fix rel-storage parsing for options with spaces. Note that split() or
split(None) already strips the string.
[mj]

1.8 (2008-04-05)

Fixed a Win32 problem in which the presence of Python string escapes in the
path to zope.conf (e.g., d:botestpartsinstanceetczope.conf would escape
the b). This showed up when using the ‘run’, ‘debug’ or ‘adduser’ commands.
This fixes #211416.
[smcmahon]
Added console command to the instance script, which is equivalent to fg but
does not implicitly turn on debug mode but respects the zope.conf setting.
[hannosch]

1.7 (2008-03-31)

Added new client-home option and let it default to a subfolder of the
buildout-wide var folder with a subfolder of the name of the section.
[hannosch]
Added limited support for running tests under Zope <= 2.8.
[hannosch]

1.6 (2008-03-27)

Fixed runzope script generation for Zope 2.8.
[hannosch]
Cleaned up “./bin/instance test” option handling.
[stefan]
Removed generator expressions as these aren’t supported in < py2.4, which is
used by zope 2.7/8.
[duffyd]

1.5 (2008-02-29)

Added access-log-custom option to be able to use another event logger
than the file one for the access logger.
[tarek]
Fix instance generation to work on Windows with blanks in the path name.
This closes #188023.
[hannosch, gotti]
Added ‘zeo-client-client’ option which results in ‘client <value>’ inside
<zeoclient>.
[timte, hannosch]
Made relstorage handling more generic, so it now supports any RelStorage
adapter, including Oracle (which was broken).
[mj]

1.4 (2008-02-23)

Fix typo in event log parameter name (from “z-log” to “z2-log”), to comply
with the documentation. This closes #190943.
[kdeldycke]
Create pid and lock file folders if they don’t exist.
[kdeldycke]
Remove hard-coded log level and use the event_log_level parameter to set it
dynamically. This closes #190994.
[kdeldycke]
Added a test environment, using zc.buildout.testing, and a doctest that
tries the recipe.
[tarek]
Added an event-log-custom option
[tarek]
Added example for the zope-conf-additional option. This closes #185539.
[klm, hannosch]
Added rel-storage option to be able to wire Zope to RelStorage
(postgresql/oracle) instead of a FileStorage database.
[tarek]

1.3

For each entry in recipe-specified ‘extra-paths’ line, add a ‘path’ line
to the instance and Zope client zope.conf files.
[klm]

1.2

Added the boolean shared-blob option, defaulting to no. If all of
zeo-client, blob-storage and shared-blob options are set,
the instance will assume the blob directory set by blob-storage is shared
with the server instead of streaming ‘blob’ files through the ZEO connection.
[rochael]
Changed ctl.do_foreground() (which is invoked by the fg command
line argument) start Zope in debug mode to emulate the behavior of
zopectl fg. This required a little special WIN32 code to make
sure it would work in both *nix and Windows.
[smcmahon]
Added var option, which is used to configure the base directory for all
the things going into var.
[hannosch]
Added zeo-var option, which is used in the zeo storage snippets to
configure the zeo var folder.
[hannosch]
Merged rochael-blobsupport branch. Added support for ZODB 3.8 blob storage
configuration for ZEO clients. This references
https://bugs.launchpad.net/collective.buildout/+bug/179113.
[rochael, hannosch]
Added zeo-client-name option. Defaults to the name of the ZEO client.
[hannosch]

1.1

Small documentation update. Added link to the bugtracker.
[hannosch]
Changed default of zope.conf option ‘default-zpublisher-encoding’ to ‘utf-8’
instead of Zope’s default value of ‘iso-8859-15’.
Have PID file’s location default to ‘buildout:directory/var/{name}.pid’.
Keeping the PID file in $INSTANCE_HOME gives trouble when buildout rebuilds
the part.
[nouri, mustapha]

1.0

Increased ‘zodb_cache_size’ default value to 5000, which is more likely a
better default these days.
[hannosch]
Added support for ‘extra-paths’ as in ‘zc.recipe.egg’; this is useful when
using regular python packages for which no eggs are available (yet), i.e.
with ‘plone.recipe.distros’.
[witsch]
Added zeo-storage option (merge branch ree-add-zeo-storage-option).
[ree]
Avoid doubled entries to eggs specified in the buildout in ‘sys.path’:
the working set (‘ws’) gets passed again when installing the script
(‘bin/instance’), but it is not also added to ‘extra_paths’.
[witsch]
Patching ‘PYTHONPATH’ in the Zope startup skripts should insert all
additional paths (to eggs) __before__ ‘SOFTWARE_HOME’, because otherwise
(newer) egg versions of components from the standard Zope distribution
(i.e. stuff that lives in ‘lib/python’) cannot be used.
[witsch]
Changed the option to suppress deprecation warnings to “–nowarn” or
‘–nowarning” to be consistent with “zopectl test”.
[witsch]
Added option “-w” to allow the test runner to suppress deprecation warnings,
so it’s easier to spot failing tests…
[witsch]
Updated import for Zope 2.7 (and below) compatibility.
[duffyd]
Merging -r51966:52659 claytron-zopeconfoptions branch to trunk.
[claytron]
Made the config snippet prettier while still getting the resulting
indentation right.
[witsch]

0.9

Added support for zodb 3.8’s “<blobstorage>” directive.
[witsch]
Added a script name arg before callint zope.testing.testrunner.run.
zope.testing.testrunner:1772, get_options removes the first arg from
the list of arguments expecting a script name there. Was causing
“bin/instance test” to behave improperly.
[rossp]

0.8

Use bin if present falling back to utilities. This makes it possible to use
a Zope version installed from a tarball and not compiled inplace.
[rossp]

0.7

Found the problem with strange environment variables.
[hannosch]
Fixed documentation bug, the cache size is respected by non-zeo instance as
well.
[hannosch]

0.6

J1m actually read the docs ;)
[hannosch]
Attempt to fix the sometimes insane number of tests which are found by the
test runner.
[hannosch]

0.5

Added an option to set the effective-user.
[optilude]

0.4

Generate a bin/repozo script to perform backups using repozo.py (and
set up the appropriate pythonpath for this to work).
[optilude]
Document options properly, and add the ability to specify a zope.conf
file explicitly rather than having one generated from a template.
[optilude]

0.3

Finally found a way to provide the Zope Windows service with the right
environment. We need a new wrapper script, which sets up the PYTHONPATH.
[hannosch]
Make it possible to configure the name of the zopectl script using the
control-script option in the [instance] section.
[wichert]

0.2

Extend support for zcml slugs to include Zope 2.9.
[dunny]
Added support for making a ZEO-client.
[regebro]

0.1

Initial implementation.
[hannosch]
