Configuration#

This appendix documents the RStudio Package Manager configuration file format and enumerates the user-configurable options.

Configuration Basics#

The RStudio Package Manager configuration file is located at /etc/rstudio-pm/rstudio-pm.gcfg. This configuration is read at startup and controls the operation of the service.

An example configuration file that includes all the available configuration settings along with their defaults is installed at /etc/rstudio-pm/rstudio-pm.gcfg.defaults.

File Format#

The RStudio Package Manager configuration file uses the gcfg (Go Config) format, which is derived from the Git Config format.

Here is an example of that format showing the different property types:

; Comment
[BooleanExamples]
property1 = true
property2 = off
property3 = 1

[IntegerExamples]
Property1 = 42
Property2 = -123

[DecimalExamples]
Property1 = 3.14
Property2 = 7.
Property3 = 2
Property4 = .217

[StringExamples]
Property1 = simple
Property2 = "quoted string"
Property3 = "escaped \"quote\" string"

[MultiStringExamples]
ListProperty = black
ListProperty = blue
ListProperty = green

[DurationExamples]
Property1 = 1000000000
Property2 = 500ms
Property3 = 1m15s  ; comment with a property

Comments always start with a semi-colon (;) or hash (#) and continue to the end of the line. Comments can be on lines by themselves or on a line with a property or section definition.

Configuration sections always begin with the name of the section bounded by square brackets. A section may appear multiple times and are additive with the last value for any property being retained. The following two configuration examples are equivalent.

[Example]
A = aligator
B = 2

[Example]
A = aardvark
C = shining
[Example]
A = aardvark
B = 2
C = shining

Each configuration property must be included in its appropriate section. Property and section names are interpreted case-insensitively.

Property definitions always have the form:

Name = value
The equals sign (=) is mandatory.

Multi-value Properties#

If a property happens to to be given more than once, only the last value is retained. The "multi" properties are an exception to this rule; multiple entries are aggregated into a list.

[MultiExample]
Color = black
Color = blue

[NonMulti]
Animal = cat
Animal = dog

If Color is a multi-string property, both the "black" and "blue" values are used. If Animal is a normal string property, only the value "dog" is retained.

Property Types#

Configuration properties all have one of the following types:

string

A sequence of characters. The value is taken as all characters from the first non-whitespace character after equal sign to the last non-whitespace character before the end-of-line or start of a comment. Double-quotes (") are supported, but usually unnecessary. A literal double-quote MUST be escaped and quoted itself like QuotedValue = "J.R. \"Bob\" Dobbs". Strings containing the comment characters ; and # also need to be quoted.

Some parameters with type string may require a valid crontab string. For more information see the appendix section on the crontab format.

encrypted-string

A potentially encrypted sequence of characters. The rules on how the value is taken from the file are the same as for the regular string type. But to generate an encrypted string one needs to enter the plain text value as-is (no quotes or escaping) in the command rspm encrypt which will output the encrypted version of the entered value. Encrypted values are tied to the RStudio Package Manager installation that generated them in most cases. For convenience and backwards compatibility, plain text values are accepted. However, in this case RStudio Package Manager will log a message on startup saying that the value should have been encrypted. See the Configuration Encryption page for more information.

multi-string

A property that takes multiple string values. The property name is listed with each individual input value. For example, providing Color = black and Color = blue results in two separate values. Defaults for multi-string configuration properties are not overridden when additional values are configured.

boolean

A truth value. The values true, yes, on, and 1 are interpreted as true. The values false, no, off, and 0 are interpreted as false.

integer

An integral value.

bytesize

A value specifying the data size. When provided as a raw number, the value is interpreted as bytes. Data size values can also be specified as a sequence of decimal numbers, each with optional fraction and unit suffix such as "10MB" for 10 megabytes, "2000" for 2000 bytes, or "1GB" for 1 gigabytes.

Valid data size units are B (bytes), KB (kilobyte), MB (megabyte), GB (gigabyte), and TB (TB).

decimal

A numeric value with an optional fractional component. Values with and without a decimal point are allowed.

duration

A value specifying a length of time. When provided as a raw number, the value is interpreted as nanoseconds. Duration values can also be specified as a sequence of decimal numbers, each with optional fraction and unit suffix, such as 300ms, 1.5h, or 1m30s.

Valid time units are ns (nanoseconds), us (microseconds), ms (milliseconds), s (seconds), m (minutes), h (hours), and d (days).

version

A string representing a version. A version may have one to four numeric components, separated by periods or hyphens. Examples include 2, 2.5, 2.5.6, 2.5.6.1, and 2.5-6-11.

Each configuration property documented in this appendix includes its description, data type, and default value.

Reloadable Properties#

Some properties are marked as "reloadable". Sending a HUP signal to the RSPM process causes the on-disk configuration to be reread. The server is reconfigured with the latest values of these reloadable properties. See the Stopping and Starting RSPM section for details about sending a HUP signal to your RSPM process.

Note

Use a HUP signal when your configuration changes are limited to properties marked as reloadable. Perform a full restart of RStudio Package Manager when changing other properties.

A HUP signal only reloads configuration settings that have explicitly changed. Commenting out a setting will not affect the configuration when using the HUP signal. If you have commented out a setting instead of changing the setting value, restart the RStudio Package Manager service instead of using the HUP signal.

Environment Variables#

Properties can also be set by environment variables on the RSPM process.

Environment variables all have the prefix PACKAGEMANAGER_ and are automatically determined by section, class, and property names. For example:

PACKAGEMANAGER_SERVER_PACKAGECACHESIZE=3000
PACKAGEMANAGER_GIT_POLLINTERVAL=10m
PACKAGEMANAGER_S3STORAGE_packages_BUCKET=your-s3-bucket

The first two would set the PackageCacheSize property in the Server section and the PollInterval property in the Git section, respectively. The last would set the Bucket property for the packages class in the S3Storage section.

Environment variables take precedence over settings in the configuration file.

Server#

The Server section contains configuration properties which apply across the whole of RStudio Package Manager and are not appropriate for the other sections, which are generally narrower.

The properties which follow all must appear after [Server] in the configuration file.

The StorageAlerts section allows customizable alerting thresholds based on a fixed size or a percentage basis. Use [StorageAlerts] to set default values or use FileStorage classes to override a specific storage location. For example, [StorageAlerts "cran"]

Alerting is enabled by default, but it can be customized or disabled completely depending on your needs. Alerting is currently supported only for FileStorage classes.

The alerting process will recursively check the free and used size of the disk on which the specified directory is mounted. For example, if your FileStorage is configured as follows, the alerting process will scan the disk on which /path/to/cran resides and report on the results.

; /etc/rstudio-pm/rstudio-pm.gcfg

[FileStorage "cran"]
Location = /path/to/cran

[StorageAlerts "cran"]
Threshold = 10%

All options are as follows.

; /etc/rstudio-pm/rstudio-pm.gcfg

[StorageAlerts]
; Enable UI alerts of type 'raw', 'safe', 'name' or disable with 'none'
; UIMessageType = safe
;
; Set a default for each underlying storage class.
; Can be a fixed size such as "10GB" or a percent like "90%"
; Disable by using 0, 0GB, 0% or not setting.
;
; The default alert threshold is 75%
; Threshold = 75%
;
; Optionally specify thresholds for individual FileStorage classes.
; These function as overrides for the default. Disable using
; one of the "0" values like above.
;
; [StorageAlerts "cache"]
; Threshold = 10GB
;
; [StorageAlerts "cran"]
; Threshold = 10%
;
; [StorageAlerts "packages"]
; Threshold = 0

StorageAlerts Settings#

Threshold#

The default threshold to alert for any storage class. May be either a percentage or a size. Must end with a '%' or a size 'GB'. For example 90% or 200GB. Leave empty to disable. Can be overridden for class-specific thresholds.

Type: string
Default: 75%

UIMessageType#

The type of message to present to the RStudio Package Manager Web UI. Must be one of 'raw' (the full message with details), 'safe' (a message without specific filesystem paths or threshold amounts), 'name' (the name of the filesystem storage class only) or 'none' (hidden from the UI). This setting cannot be overridden by class-specific configuration. Note, the server log will always contain the raw alert value.

Type: string
Default: name

FileStorage#

The FileStorage section contains configuration properties which control where files are stored. You can configure a FileStorage section for any of eight classes of data:

  • binaries
  • bioconductor
  • cache
  • cran
  • launcher
  • metrics
  • packages
  • pypi

If you wish to change the base storage location for all RStudio Package Manager data, please use the Server.DataDir property instead. Use a FileStorage configuration section only when you wish to change the storage location for a particular class of data.

For example, to configure a custom storage location for the cache, you would create the following configuration section:

; /etc/rstudio-pm/rstudio-pm.gcfg

[FileStorage "cache"]
Location = /path/to/cache

FileStorage Settings#

Location#

The directory to use for this storage class.

Type: string
Default: {Server.DataDir}/{StorageClass}

S3Storage#

The S3Storage section contains configuration properties which control where files are stored on S3. You can configure an S3Storage section for any of eight classes of data:

  • binaries
  • bioconductor
  • cache
  • cran
  • launcher
  • metrics
  • packages
  • pypi

If you wish to use S3 for all variable data classes, please use a generic S3Storage configuration section. You can then override the generic settings for any storage class as necessary. For example:

; /etc/rstudio-pm/rstudio-pm.gcfg

[Storage]
Default = s3

; Default S3 settings. This is the minimum-required setting for using S3.
[S3Storage]
Bucket = your-s3-bucket

; Override default S3 settings for the "packages" class. This demonstrates
; all the available S3 configuration settings.
[S3Storage "packages"]
Bucket = another-s3-bucket
Prefix = rspm-packages
Profile = dev-rspm
Region = us-west-1
EnableSharedConfig = true

Alternatively, you can specifiy each variable data class separately:

; /etc/rstudio-pm/rstudio-pm.gcfg

[Storage]
Cache = s3
Launcher = s3
Metrics = s3
Packages = s3
CRAN = s3
Bioconductor = s3
Binaries = s3
PyPI = s3

[S3Storage]
Bucket = your-s3-bucket

S3Storage Settings#

Bucket#

S3 bucket to use. Required.

Type: string
Default: <empty-string>

Prefix#

Prefix to prepend to item address. This is useful for organizing a shared S3 bucket. Optional.

Type: string
Default: {StorageClass}

Profile#

AWS Profile to use. This can also be defined through environment variables, the shared credentials file, or through the shared configuration file (if SharedConfig is enabled). Optional.

Type: string
Default: <empty-string>

Region#

AWS Region to use. This can also be defined through environment variables, the shared credentials file, or through the shared configuration file (if SharedConfig is enabled).

Type: string
Default: <empty-string>

KMSKeyID#

The AWS KMS ID to use for client-side S3 encryption. Note that this is NOT backwards compatible with existing installations. Optional.

Type: string
Default: <empty-string>

EnableSharedConfig#

Overrides the AWS_SDK_LOAD_CONFIG env var value and enables the shared config functionality. Optional

Type: boolean
Default: false

EvictionPolicy#

Eviction policies can be used to keep server disk usage to a minimum. The Server.EvictedStorageClasses setting enables general eviction, however the EvictionPolicy section allows custom control of the objects in each class. You can configure a default EvictionPolicy section to control the lifetime of every cache object, or create custom EvictionPolicy sections for six classes of data if you need fine-grained control:

  • binaries
  • bioconductor
  • cache
  • cran
  • metrics
  • pypi

The Server.EvictionInterval and Server.EvictionSweepSchedule settings in the Server Configuration control when evictions occur. These two settings correspond to the two types of evictions:

Normal Eviction

  • Runs at intervals defined by Server.EvictionInterval, and removes any assets in storage that have a last recorded access time that is older than the MaxAge setting for the storage class. The last recorded access times are stored in the RSPM database and managed by the RSPM service.

Sweep Eviction

  • Removes orphaned items by enumerating all assets in persistent storage and deleting any for which we have no corresponding database record. A "sweep" eviction is more time consuming, and it runs on the schedule defined by Server.EvictionSweepSchedule.

Example:

; /etc/rstudio-pm/rstudio-pm.gcfg

[Server]
EvictedStorageClasses = "cache, metrics, cran, binaries"
EvictionInterval = 1h
EvictionSweepSchedule = "30 2 * * *"

; Defaults
[EvictionPolicy]
MaxAge = 720h

; Override for a specific persistent storage class
[EvictionPolicy "binaries"]
MaxAge = 300h

EvictionPolicy Settings#

MaxAge#

The duration of no access after which a file from a persistent class is considered stale.

Type: duration
Default: 720h

Exceptions#

A regular expression whose matches will not be evicted from persistent storage unless orphaned. To ignore default exceptions and use no exceptions for a particular storage class, use the string none.

Type: multi-string
Default: unspecified

Migration#

The Migration section contains configuration properties that control the migrations that occur upon upgrading to a new RStudio Package Manager version.

Migration Settings#

EnableMixedClassMigration#

Enables migration of CRAN packages to another storage class.

Type: boolean
Default: false

Swagger#

The Swagger section contains configuration properties that control the Server API documentation page served by the server.
