Controls whether AWS instance analytics events are published. This setting only has an effect if analytics is enabled.

application.mode

Controls what mode Bitbucket is in - currently "mirror" and "default" are supported

attachment.upload.max.size

Defines the largest single attachment the system will allow. Attachments larger than this will be rejected without ever being stored locally.

This setting applies to all uploaded data, including avatars. Some types may have their own further restriction they apply on top of this. However, for such types, the file will be stored locally prior to that secondary limit being applied. If that secondary limit is higher than this limit, this limit is the one that will be applied.

This value is in bytes.

audit.details.max.length

Defines the number of characters that can be can stored as details in a single audit entry. This property is only applicable to legacy (pre 7.0) audit log file. This property is effective only when audit.legacy.log=true

audit.legacy.events.logging.forced

This property controls whether ADVANCED or FULL level logging is enforced for actions that were audited prior to application version 7.0. If this property is set as true, those actions will be audited regardless of coverage settings.

audit.legacy.log

In version 7.0, a new format of audit log file was introduced. This property controls whether audit events are logged to the legacy (pre 7.0) audit log file, in addition to the new format. This property exists to ease the transition from the legacy audit log file to the new format and will be removed in 8.0.

plugin.audit.search.max.concurrent.nontext.requests

Maximum number of concurrent non-freetext search requests allowed, defaults to 10 per node

plugin.audit.search.max.concurrent.text.requests

Maximum number of concurrent freetext search requests allowed, defaults to 10 per node

auth.cache.tti

Controls the time-to-idle for entries in the authentication cache. A short TTI (5 to 10 seconds) helps narrow the window for malicious users authenticating with outdated credentials and is recommended. Setting this to a value less than 1 will default it to the configured TTL (auth.cache.ttl).

This value is in seconds.

auth.cache.ttl

Controls the time-to-live for entries in the authentication cache. Setting this to a value less than 1 will disable the cache. The maximum allowed value is 300 seconds (5 minutes). Longer TTLs pose a security risk, as potentially out-of-date credentials can still be used while they remain in the cache. A short TTL, like the default, can reduce burst load on remote authentication systems (Crowd, LDAP) while keeping potential exposure to outdated credentials low, especially when paired with a shorter TTI.

This value is in seconds.

auth.remember-me.enabled

Controls whether remember-me authentication is disabled, always performed or only performed when a checkbox is checked on the login form. The 'Remember my login' checkbox is only displayed when set to 'optional'. Possible values are:

• always

  No checkbox, remember-me cookie is always generated on successful login.

• optional

  Checkbox is displayed on login form. Remember-me cookie is only generated when checkbox is checked.

• never

  Remember-me authentication is disabled completely.

auth.remember-me.cookie.name

Defines the cookie name used for the remember-me authentication

This value is in seconds

auth.remember-me.token.cleanup.interval

Controls how frequently expired remember-me tokens are cleaned up.

This value is in minutes

plugin.auth-crowd.sso.enabled

Whether SSO support should be enabled or not. Regardless of this setting SSO authentication will only be activated when the system is connected to a Crowd directory that is configured for SSO.

plugin.auth-crowd.sso.config.ttl

The auth plugin caches the SSO configuration that is retrieved from the remote Crowd server. This setting controls the time to live of that cache.

This value is in minutes.

plugin.auth-crowd.sso.config.error.wait

If an error occurs while retrieving the SSO configuration from the remote Crowd server, the system will wait this long before retrying. The wait time between subsequent attempts is incremented exponentially (1s -> 1.5s -> 2.3s -> 3.4s, etc). The wait time is capped at the configured TTL.

This value is in seconds.

plugin.auth-crowd.sso.http.max.connections

The maximum number of HTTP connections in the connection pool for communication with the Crowd server.

plugin.auth-crowd.sso.http.proxy.host

The name of the proxy server used to transport SOAP traffic to the Crowd server.

plugin.auth-crowd.sso.http.proxy.port

The connection port of the proxy server (must be specified if a proxy host is specified).

plugin.auth-crowd.sso.http.proxy.password

The password used to authenticate with the proxy server (if the proxy server requires authentication).

plugin.auth-crowd.sso.http.timeout

The HTTP connection timeout used for communication with the Crowd server. A value of zero indicates that there is no connection timeout.

This value is in milliseconds.

plugin.auth-crowd.sso.socket.timeout

The socket timeout. You may wish to override the default value if the latency to the Crowd server is high.

This value is in milliseconds.

plugin.auth-crowd.sso.session.validationinterval

The number of minutes to cache authentication validation in the session. If this value is set to 0, each HTTP request will be authenticated with the Crowd server.

plugin.auth-crowd.sso.session.lastvalidation

The session key to use when storing a Date value of the user's last authentication.

plugin.auth-crowd.sso.session.tokenkey

The session key to use when storing a String value of the user's authentication token.

avatar.max.dimension

Controls the max height and width for an avatar image. Even if the avatar is within the acceptable file size, if its dimensions exceed this value for height or width, it will be rejected. When an avatar is loaded by the server for processing, images with large dimensions may expand from as small as a few kilobytes on disk to consume a substantially larger amount of memory, depending on how well the image data was compressed. Increasing this limit can substantially increase the amount of heap used while processing avatars and may result in OutOfMemoryErrors.

This value is in pixels.

avatar.max.size

Controls how large an avatar is allowed to be. Avatars larger than this are rejected and cannot be uploaded to the server, to prevent excessive disk usage.

This value is in bytes.

avatar.url.default

Defines the fallback URL to be formatted into the "avatar.url.format.http" or "avatar.url.format.https" URL format for use when a user does not have an acceptable avatar configured. This value may be a URL or, if using Gravatar, it may be the identifier for one of Gravatar's default avatars.

avatar.url.format.http

Defines the default URL format for retrieving user avatars over HTTP. This default uses any G-rated avatar provided by the Gravatar service

The following format parameters are available:

• %1$s

  The user's e-mail address, MD5 hashed, or "00000000000000000000000000000000" if the user has no e-mail.

• %2$d

  The requested avatar size.

• %3$s

  The fallback URL, URL-encoded, which may be defined using "avatar.url.default".

• %4$s

  The user's e-mail address, not hashed, or an empty string if the user has no e-mail.

avatar.url.format.https

Defines the default URL format for retrieving user avatars over HTTPS. This default uses any G-rated avatar provided by the Gravatar service

The following format parameters are available:

• %1$s

  The user's e-mail address, MD5 hashed, or "00000000000000000000000000000000" if the user has no e-mail.

• %2$d

  The requested avatar size.

• %3$s

  The fallback URL, URL-encoded, which may be defined using "avatar.url.default".

• %4$s

  The user's e-mail address, not hashed, or an empty string if the user has no e-mail.

backup.drain.scm.timeout

Controls how long the backup should wait for outstanding SCM operations to complete before failing.

This value is in seconds.

backup.drain.db.timeout

Draining database connections during backup happens in two stages. Stage 1 passively waits a set amount of time for all connections to be returned to the pool. If connections are still leased when backup.drain.db.timeout seconds has elapsed then stage 2 begins and will interrupt the owning threads, wait backup.drain.db.force.timeout seconds and finally attempt to roll back and close any remaining connections.

In stage 1 of draining connections during backup, this setting controls how long the backup should wait for outstanding database operations to complete before moving to stage 2. See backup.drain.db.force.timeout

This value is in seconds.

backup.drain.db.force.timeout

In stage 2 of draining connections during backup, this property controls how long the backup process should wait (after interrupting the owning threads) for those threads to release the connections before forcibly rolling back and closing them. Note if all connections have been returned to the pool stage 2 is skipped and so this property has no effect. A negative value will skip stage 2 completely. See backup.drain.db.timeout

This value is in seconds.

plugin.bitbucket-branch-information.timeout

Controls timeouts for retrieving branch information, which for large repositories can be quite slow and consume a single Git process.

This value is in seconds.

plugin.bitbucket-branch-information.max.branches

Controls the maximum number of branches that are shown the user

plugin.bitbucket-auto-merge.limit

Defines the maximum number of merges allowed along in single automatic merge chain. If the number of merges included in the chain exceeds this limit, the entire chain will be skipped. Setting this limit to 0 means automatic merging is effectively disabled, since the merge chain must always be empty.

plugin.bitbucket-auto-merge.timeout

Defines the maximum amount of time any command used to perform a single automatic merge from the chain is allowed to execute or idle. Since an automatic merge may require a series of different commands at the SCM level, this timeout does not define the upper bound for how long the overall merge process might take; it only defines the duration allotted to any single command.

This value is in seconds.

plugin.bitbucket-branch-model.version.separator

The version component separator for branch model. This value is a regular expression pattern that is used to split branch names parsed as version strings into separate components for comparison. The default value results in any of the following 4 characters being used for comparison: _ - + .

The maximum number of concurrent requests to a remote CI system.

hazelcast.node.authentication.enabled

Enable node authentication. When this is enabled the group name and password are verified before any other checks are run

hazelcast.enterprise.license

Specifies a Hazelcast enterprise license. An enterprise license is not required, but supplying one will unlock additional Hazelcast functionality, such as the ability to use the Hazelcast Management Center with clusters containing more than 2 nodes, which may be useful in production environments.

hazelcast.managementcenter.url

Specifies the URL where the Hazelcast Management Center is running. When a URL is configured each node in the cluster will connect to the Management Center at that URL and broadcast its status.

hazelcast.group.name

Specifies the cluster group the instance should join. This can be used, for example, to partition development and production clusters.

hazelcast.group.password

The password required to join the specified cluster group.

hazelcast.http.sessions

Specifies how HTTP sessions should be managed.

The following values are supported:

• local

  HTTP sessions are managed per node. When used in a cluster, the load balancer MUST have sticky sessions enabled. If a node fails or is shut down, users that were assigned to that node need to log in again.

• sticky

  HTTP sessions are distributed across the cluster with a load balancer configured to use sticky sessions. If a node fails or is shut down, users do not have to log in again. In this configuration, session management is optimized for sticky sessions and will not perform certain cleanup tasks for better performance.

• replicated

  HTTP sessions are distributed across the cluster. The load balancer does not need to be configured for sticky sessions.

local is the recommended setting for standalone installations. For clustered installations local is the most performant option, followed by sticky and replicated.

hazelcast.local.public.address

In most environments it should not be necessary to configure this explicitly. However, when using NAT, such as when starting cluster nodes using Docker, it may be necessary to configure the public address explicitly to avoid request binding errors.

If hazelcast.network.aws is true and hazelcast.network.aws.iam.role is not set, then you must set this property to your AWS account secret key, in order to discover your cluster node instances via the AWS EC2 API.

hazelcast.network.aws.region

The AWS region to query. If empty, Hazelcast's default ("us-east-1") is used. If set, it will override any value for "hazelcast.network.aws.host.header" (see below).

hazelcast.network.aws.host.header

The Host: header to use when querying the AWS EC2 API. If empty, then Hazelcast's default ("ec2.amazonaws.com") is used. If set, then "hazelcast.network.aws.region" shouldn't be set as it will override this property.

hazelcast.network.aws.port.range

Port to connect to on instances found via the AWS discovery mechanism. Can be a port range in the format 5701-5703 or single port. Providing a range with more than 3 ports may impact the application startup time. By default this is set to the value of the hazelcast.port property

hazelcast.network.aws.security.group.name

There are 2 mechanisms for filtering out AWS instances and these mechanisms can be combined (AND).

• If hazelcast.network.aws.security.group.name is set, only instances within that security group will be selected.

• If hazelcast.network.aws.tag.key and hazelcast.network.aws.tag.value are set, only instances with that tag key/value will be selected.

hazelcast.network.aws.tag.key

The AWS tag key to use to filter instances to form a cluster with.

hazelcast.network.aws.tag.value

The AWS tag value to use to filter instances to form a cluster with.

hazelcast.network.azure

A boolean flag to indicate whether Hazelcast has Azure Auto Discovery enabled. When setting this property to true, hazelcast.network.azure.cluster.id, hazelcast.network.azure.group.name and hazelcast.network.azure.subscription.id become required properties. If Azure system-assigned managed identity is not enabled for the Bitbucket VMs then hazelcast.network.azure.client.id, hazelcast.network.azure.client.secret and hazelcast.network.azure.tenant.id are also required properties.

hazelcast.network.azure.cluster.id

If hazelcast.network.azure is true, then you must set this property to the name of the tag on the hazelcast vm or scale set resources, the value of the tag should be the port that hazelcast will use to communicate

hazelcast.network.azure.group.name

If hazelcast.network.azure is true, then you must set this property to the Azure resource group name of the cluster

hazelcast.network.azure.subscription.id

If hazelcast.network.azure is true, then you must set this property to your Azure subscription ID

hazelcast.network.azure.client.id

If hazelcast.network.azure is true and Azure system-assigned managed identity is not enabled for the Bitbucket VMs, then you must set this property to your Azure Active Directory Service Principal client ID

hazelcast.network.azure.client.secret

If hazelcast.network.azure is true and Azure system-assigned managed identity is not enabled for the Bitbucket VMs, then you must set this property to your Azure Active Directory Service Principal client secret

hazelcast.network.multicast

A boolean flag to indicate whether Hazelcast has multicasting enabled.

hazelcast.network.multicast.address

The multicast address for the cluster, used to locate members when multicast discovery is enabled. If no value is set here, Hazelcast's default (224.2.2.3) is used. This value should not need to be configured explicitly on most networks.

hazelcast.network.multicast.port

The multicast port to bind to. By default, this will be the hazelcast.port (5701, unless configured otherwise), and updating that setting will also update this one unless this port is configured explicitly.

hazelcast.network.tcpip

A boolean flag to indicate whether Hazelcast has TCP/IP enabled.

hazelcast.network.tcpip.members

List of members that Hazelcast nodes should connect to when TCP/IP is enabled. These nodes function as root nodes, allowing cluster nodes to discover each other. This comma-separated list does not need to include every node in the cluster. When new nodes join they will use the connected node to find the other cluster nodes.

hazelcast.port

The network port where Hazelcast will listen for cluster members. If multiple instances are run on the same server Hazelcast will automatically increment this value for additional nodes.

plugin.bitbucket-code-insights.reports.expiry.days

plugin.bitbucket-comment-likes.max.page

The maximum size of a page of comment likes

plugin.bitbucket-comment-likes.max.reactions

The maximum number of specific comment reactions for a single comment. The system will not allow you to add more of the same reaction.

indexing.max.threads

Controls the maximum number of threads which are used to perform indexing. The resource limits configured below are not applied to these threads, so using a high number may negatively impact server performance.

indexing.import.max.threads

Controls the maximum number of threads which are used to perform indexing during Data Center migration imports. The resource limits configured below are not applied to these threads, so using a high number may negatively impact server performance.

indexing.job.batch.size

Defines the number of commits which will be indexed in a single database transaction.

indexing.job.queue.size

Defines the maximum number of pending indexing requests. When this limit is reached, attempts to queue another indexing operation will be rejected.

indexing.queue.timeout.poll

Defines the size of the queue that will be used for indexing. When the limit is reached the program will block until there is space in the queue to add any required new items.

indexing.process.timeout.execution

Controls how long indexing processes are allowed to execute before they are interrupted, even if they are producing output or consuming input.

This value is in seconds.

indexing.snapshot.timeout.execution

Defines whether file history commands in the UI should follow renames by default. This feature can be disabled as it may cause significant load for repositories with long commit logs.

commit.message.max

Controls the maximum length of the commit message to be loaded when retrieving one or more commits from the SCM. Commit messages longer than this limit will be truncated. The default limit is high enough to not affect processing for the general case, but protects the system from consuming too much memory in exceptional cases.

commit.message.bulk.max

Controls the maximum length of the commit message to be loaded when bulk retrieving a commits from the SCM. Commit messages longer than this limit will be truncated. The default limit is high enough to not affect processing for the common case, but protects the system from consuming too much memory when many commits have long messages.

Maximal size of thread pool – the maximum number of concurrent migrations.

jdbc.driver

The JDBC driver class that should be used to connect to the database.

The system uses an internal database by default, and stores its data in the home directory.

The following JDBC drivers are bundled with the distribution:

• com.microsoft.sqlserver.jdbc.SQLServerDriver (more info)

• oracle.jdbc.OracleDriver (more info)

• org.postgresql.Driver (more info)

The JDBC driver for MySQL is not bundled, due to licensing restrictions; administrators will need to download and install that driver manually. See Connecting to MySQL for instructions.

jdbc.url

This is the JDBC URL that will be used to connect to the database. This URL varies depending on the database you are connecting to. Please consult the documentation for your JDBC driver to determine the correct URL.

jdbc.user

This is the user that will be used to authenticate with the database. This user must have full DDL rights. It must be able to create, alter and drop tables, indexes, constraints, and other SQL objects, as well as being able to create and destroy temporary tables.

jdbc.password

The password that the user defined by jdbc.user will connect with. This will be decrypted by the class mentioned in the jdbc.password.decrypter.classname property if defined.

jdbc.password.decrypter.classname

Fully qualified name of the class that's used for decrypting jdbc.password. This class must implement the com.atlassian.db.config.password.Cipher interface, and must be available on the classpath. Do not specify this parameter if jdbc.password isn't encrypted.

db.pool.rejectioncooldown

When a connection cannot be leased because the pool is exhausted, the stack traces of all threads which are holding a connection will be logged. This defines the cooldown that is applied to that logging to prevent spamming stacks in the logs on every failed connection request.

This value is in minutes

db.pool.size.idle

Defines the number of connections the pool tries to keep idle. The system can have more idle connections than the value configured here. As connections are borrowed from the pool, this value is used to control whether the pool will eagerly open new connections to try and keep some number idle, which can help smooth ramp-up for load spikes.

db.pool.size.max

Defines the maximum number of connections the pool can have open at once.

db.pool.timeout.connect

Defines the amount of time the system will wait when attempting to open a new connection before throwing an exception. The system may hang, during startup, for the configured number of seconds if the database is unavailable. As a result, the timeout configured here should not be generous.

This value is in seconds.

db.pool.timeout.idle

Defines the maximum period of time a connection may be idle before it is closed. In general, generous values should be used here to prevent creating and destroying many short-lived database connections (which defeats the purpose of pooling).

Note: If an aggressive timeout is configured on the database server, a more aggressive timeout must be used here to avoid issues caused by the database server closing connections from its end. The value applied here should ensure the system closes idle connections before the database server does. This value needs to be less than db.pool.timeout.lifetime otherwise the idle timeout will be ignored.

This value is in seconds.

db.pool.timeout.leak

Defines the maximum period of time a connection may be checked out before it is reported as a potential leak. By default, leak detection is not enabled. Long-running tasks, such as taking a backup or migrating databases, can easily exceed this threshold and trigger a false positive detection.

This value is in minutes.

db.pool.timeout.lifetime

Defines the maximum lifetime for a connection. Connections which exceed this threshold are closed the first time they become idle and fresh connections are opened.

This value is in minutes.

db.schema.lock.maxWait

Defines the maximum amount of time the system can wait to acquire the schema lock. Shorter values will prevent long delays on server startup when the lock is held by another instance or, more likely, when the lock was not released properly because a previous start was interrupted while holding the lock. This can happen when the system is killed while it is attempting to update its schema.

This value is in seconds.

db.schema.lock.pollInterval

Defines the amount of time to wait between attempts to acquire the schema lock. Slower polling produces less load, but may delay acquiring the lock.

This value is in seconds.

diagnostics.alert.dispatcher.max.threads

The maximum number of alert dispatcher threads. The number of dispatcher threads will only be increased when the alert queue is full and this configured limit has not been reached.

diagnostics.alert.dispatcher.queue.size

The number of events that can be queued. When the queue is full and no more threads can be created to handle the events, events will be discarded.

diagnostics.issues.event.dropped.threaddump.cooldown.seconds

Configures how often thread dumps should be generated for alerts relating to dropped events. Taking thread dumps can be computationally expensive and may produce a large amount of data when run frequently.

This value is in seconds

diagnostics.issues.event.slow.listener.time.millis

Configures when an alert is raised for a slow event listener. If an event listener takes longer than the configured time to process an event, an warning alert is raised and made visible on the System Health page.

This value is in milliseconds

diagnostics.issues.event.slow.listener.overrides

Configures overrides for specific event listeners and/or specific plugins. This setting can be used to suppress 'slow event listener detected' alerts for specific event listeners or plugins. The value should be comma-separated list of configurations of individual triggers, where a trigger is either the plugin-key, or the plugin-key followed by the event listener class name.

Overrides are only considered if they specify more tolerant limits than the value specified in the diagnostics.issues.event.slow.listener.time.millis value. Setting a shorter override (e.g. 1000 when the default is 15000) will have no effect.

The following example sets the trigger for the com.company.example-plugin to 60s and sets the limit for the com.company.RepositoryCreatedListener event listener in the same plugin to 30s.

com.company.example-plugin:60000, com.company.example-plugin.com.company.RepositoryCreatedListener:30000

Configured values are in milliseconds

diagnostics.issues.hookscript.slow.time.seconds

Defines the maximum amount of time an individual hook script is allowed to execute or idle before a warning would be logged in the diagnostics plugin.

This value is in seconds. The default is 30 seconds, with a 10 second minimum

diagnostics.alert.retention.time.minutes

Configures the minimum amount of time alerts are kept in the database before being periodically truncated. The default (43200 minutes) is 30 days.

This value is in minutes

diagnostics.alert.truncation.interval.minutes

Configures the interval at which alerts are truncated from the database; in case of a fresh instance (or full cluster) (re-)start, this is also the initial offset until the truncation is executed for the first time. The default (1440 minutes) is 24 hours.

This value is in minutes

display.max.source.lines

Password for connecting to an Elasticsearch instance.

plugin.search.elasticsearch.aws.region

AWS region Bitbucket is running in. When set, enables request signing for Amazon Elasticsearch Service.

plugin.search.indexing.max.batch.size

Maximum size of indexing batches sent to Elasticsearch. This value should be less than the maximum content length for http request payloads supported by Elasticsearch. The default value is 15_728_640 (=15MB). (Note that for Elasticsearch instances running on AWS, this value must be less than the Network Limit size of the Elasticsearch instance).

This value is in bytes.

event.dispatcher.core.threads

The minimum number of threads that is available to the event dispatcher. The ${scaling.concurrency} variable is resolved to the number of CPUs that are available.

event.dispatcher.max.threads

The maximum number of event dispatcher threads. The number of dispatcher threads will only be increased when the event queue is full and this configured limit has not been reached.

event.dispatcher.queue.size

The number of events that can be queued. When the queue is full and no more threads can be created to handle the events, events will be discarded.

event.dispatcher.queue.rejectioncooldown

When an event cannot be dispatched because the queue is full, the stack traces of all busy event processing threads will be logged. This defines the cooldown that is applied to that logging to prevent spamming the stacks in the logs on every rejected event.

This value is in minutes

event.dispatcher.keepAlive

The time a dispatcher thread will be kept alive when the queue is empty and more than core.threads threads are running.

This value is in seconds.

executor.max.threads

Controls the maximum number of threads allowed in the common ExecutorService. This ExecutorService is used by for background tasks, and is also available for plugin developers to use. When more threads are required than the configured maximum, the thread attempting to schedule an asynchronous task to be executed will block until a thread in the pool becomes available. By default, the pool size scales with the number of reported CPU cores. Note: A minimum of 4 is enforced for this property. Setting the value to a lower value will result in the default 4 threads being used.

feature.attachments

Controls whether users are allowed to upload attachments to repositories they have access to. If this feature is enabled and later disabled, attachments which have already been uploaded are not automatically removed.

feature.auth.captcha

Controls whether to require CAPTCHA verification when the number of failed logins is exceeded. If enabled, any client who has exceeded a set limit for failed logins using either the web interface or Git hosting will be be required to authenticate in the web interface and successfully submit a CAPTCHA before continuing. Disabling this will remove this restriction and allow users to incorrectly authenticate as many times as they like without penalty.

Warning: It is strongly recommended to keep this setting enabled. Disabling it has the following ramifications:

• Users may lock themselves out of any underlying user directory service (LDAP, Active Directory etc) because the system will pass through all authentication requests (regardless of the number of previous failures) to the underlying directory service.

• For installations where Bitbucket Server is used for user management or a directory service with no limit on failed login attempts is used, the system will be vulnerable to brute-force password attacks.

feature.commit.graph

Controls whether a commit graph is displayed to the left of the commits on the repository commits page.

feature.diagnostics

Controls whether diagnostics is enabled. Diagnostics looks for known anti-patterns such as long-running operations being executed on event processing threads and identifies the responsible plugins. Diagnostics adds a little bit of overhead, and can be disabled if necessary.

feature.file.editor

Controls whether users can edit repository files in the browser and via REST.

When set to false, the edit UI and REST interface are disabled globally.

feature.forks

Controls whether repositories can be forked. This setting supersedes and overrides instance-level configuration. If this is set to false, even repositories which are marked as forkable cannot be forked.

feature.getting.started.page

Controls whether new users are redirected to a getting started page after their first login.

feature.git.rebase.workflows

Controls whether rebase workflows are enabled for Git repositories. This can be used to fully disable all of the Git SCM's built-in rebase support, including:

• "Rebase and fast-forward" and "Rebase and merge" merge strategies - "Rebase" action for pull requests - "Rebase" action for ref sync

When this feature is disabled, repository administrators and individual users cannot override it. However, third-party add-ons can still use the Java API to rebase branches or perform rebase "merges".

feature.data.center.migration.export

Controls whether Data Center migration archives can be generated on this instance.

feature.data.center.migration.import

Controls whether Data Center migration archives can be imported into the instance. Note that this feature is only available for Data Center installations

feature.personal.repos

When set to false, personal repository creation is disabled globally.

feature.public.access

Public access allows anonymous users to be granted access to projects and repositories for read operations including cloning and browsing repositories. This is controlled normally by project and repository administrators but can be switched off system wide by setting this property to false. This can be useful in sensitive environments.

feature.pull.request.auto.decline

Controls whether the process of automatically declining inactive pull requests is enabled for the system.

When this feature is enabled, all pull requests that are inactive (no recent comments, pushes etc.) are declined. Individual projects or repositories are still able to opt-out or configure a different inactivity period. When this feature is disabled, it overrides any configuration applied to individual projects or repositories, and prevents any pull request from being automatically declining due to inactivity.

feature.pull.request.deletion

Controls whether the system allows pull requests to be deleted via the UI and REST. Disabling this feature will prevent pull request deletion in all repositories, including by admins and sysadmins, and will override any settings applied to individual repositories.

feature.pull.request.suggestions

Controls whether the system allows users to add pull request suggestions through inline comments via the UI.

feature.rate.limiting

Controls whether HTTP requests will be rate limited per user. If this is enabled, repeated HTTP requests from the same user in a short time period may be rate limited. If this is disabled, no requests will be rate limited.

feature.repository.delete.policy

Controls whether a user can delete a repository by checking their permission level against the repository delete policy. Note that this feature is only available for Data Center installations

feature.rolling.upgrade

Controls whether rolling upgrade can be performed for bug-fix versions. Note that this feature is only available for Data Center installations.

feature.smart.mirrors

Controls whether smart mirrors can be connected to the instance. Note that this feature is only available for Data Center installations

footer.links.contact.support

Controls whether the Contact Support link is displayed in the footer. If this is not set, then the link is not displayed. Otherwise, the link will redirect to the URL or email that is provided.

Example formats:

• https://support.example.com/

• mailto: support@example.com

plugin.bitbucket-repository-ref-sync.fetch.timeout

Defines the maximum amount of time fetch commands used to synchronize branches in bulk are allowed to execute or idle. Because fetch commands generally produce the majority of their output upon completion, there is no separate idle timeout. The default value is 5 minutes.

This value is in seconds.

plugin.bitbucket-repository-ref-sync.merge.timeout

Defines the maximum amount of time any command used to merge upstream changes into the equivalent branch in a fork is allowed to execute or idle. Since merging branches may require a series of different commands at the SCM level, this timeout does not define the upper bound for how long the overall merge process might take; it only defines the duration allotted to any single command.

This value is in seconds.

plugin.bitbucket-repository-ref-sync.rebase.timeout

Defines the maximum amount of time any command used to rebase a fork branch against upstream changes is allowed to execute or idle. Since merging branches may require a series of different commands at the SCM level, this timeout does not define the upper bound for how long the overall rebase process might take; it only defines the duration allotted to any single command.

This value is in seconds.

plugin.bitbucket-repository-ref-sync.threads

Controls the number of threads used for ref synchronization. Higher values here will help synchronization keep up with upstream updates, but may produce noticeable additional server load.

server.shutdown

Controls whether Tomcat, SSH server and job scheduler should be shutdown gracefully or immediately. When graceful shutdown is enabled, this is how different components would behave after shutdown is initiated - * Tomcat stops accepting new HTTP connections but active connections are not interrupted. * Ssh server stops accepting new SSH connections but active connections are not interrupted. * Job scheduler does not start any new jobs but currently running jobs are not cancelled.

System will allow above components to shutdown gracefully for some time which can be controlled by property graceful.shutdown.timeout. If value of this property is set as immediate, then HTTP/SSH requests and scheduled jobs will not be waited for completion and will be terminated abruptly in their usual shutdown lifecycle.

graceful.shutdown.timeout

This is the minimum time for which system is guaranteed to wait for currently active HTTP/SSH requests and scheduled jobs to finish before terminating them. If you are using stop-bitbucket.sh to stop Bitbucket, the value of this property is effective only if it is less than or equal to the value of BITBUCKET_SHUTDOWN_TIMEOUT environment variable. It is recommended to set the value of this property at least 10 seconds less than BITBUCKET_SHUTDOWN_TIMEOUT environment variable.

This value is in seconds

hookscripts.output.max

Applies a limit to how many bytes a single hook script can write to stderr or stdout. The limit is enforced separately for each, so a limit of 32768 allows for a maximum of 65536 bytes of combined output from a single script. Output beyond the configured limit is truncated, and a message is included to indicate so.

This value is in bytes. The default is 32K, with a 16K minimum.

hookscripts.path.shell

Defines the location of bash.exe, which is used when invoking hook scripts on Windows. This property is ignored on other platforms; only Windows requires using a shell to invoke hook scripts.

hookscripts.size.max

The size a script can be when it is uploaded.

This value is in bytes.

hookscripts.timeout

Defines the maximum amount of time an individual hook script is allowed to execute or idle. Since multiple hook scripts can be registered, this timeout does not define an upper bound for how long overall execution can take; it only defines the duration allotted to any single hook script.

This value is in seconds. The default is 120 seconds, with a 30 second minimum

Job history in the "RunDetails" class available to plugins from atlassian-scheduler is only valid for the last run of the job on the same cluster node. Calls to retrieve RunDetails for the same job on different cluster nodes may return different results.

This value is in days. The value cannot be negative.

scheduler.refresh.interval.minutes

Controls the frequency at which the scheduler will automatically poll for changes to clustered jobs. If the value is positive, then the scheduler will refresh its queue of clustered jobs at the specified interval in minutes. If the value is 0 or negative, then jobs submitted on one cluster node will never be scheduled on other cluster nodes. It is not recommended to modify this setting unless recommended by Atlassian Support.

This value is in minutes. Using 0, or a negative value, disables clustering of background jobs completely.

scheduler.shutdown.timeout

The number of seconds to wait for running jobs to end after calling 'shutdown' on the scheduler service.

This property is deprecated and, as of 7.8, it no longer does anything. It will be removed in 8.0.

This value is in seconds.

plugin.mirroring.ssh.proxy.enabled

For mirror instances, this controls whether compatible SCM commands are proxied to the upstream on behalf of the user.

If enabled, such commands are performed on the upstream by the mirror acting with the same user identity, rights and privileges as the user executing the command on the mirror.

If disabled, an error message will be sent to the user unless the command can be safely executed on the mirror (e.g. whoami).

Note that SSH push proxying is not supported for mirrors of bitbucket.org and this flag is ignored.

plugin.mirroring.ssh.proxy.parseconfig

This controls whether the SSH client created to proxy SCM commands is configured with the runtime user's SSH config file (usually found at ~/.ssh/config)

Note: this caches both authentication successes (valid username/password, SSH key registered to user) but also failures (incorrect username/password pairs, unknown SSH keys).

Also note: that cache entries expire after they are inserted, not after the last access. Repeatedly making authentication requests to the mirror with the same credentials will not prevent expiry of the result from the cache.

This value is in seconds.

A positive value will cache an authentication result for the configured period. A non-positive value will disable the cache and cause all authenticated requests to be executed remotely every time. Defaults to 5 minutes.

plugin.mirroring.upstream.auth.cache.max

Configures the maximum number of authentication cache entries. Cache entries for Bitbucket Server mirrors can be heavy for certain permission schemes so this setting can control how much memory is devoted to this cache.

Note: this caches both authentication successes (valid username/password, SSH key registered to user) but also failures (incorrect username/password pairs, unknown SSH keys).

Also note: that cache entries expire after they are inserted, not after the last access. Repeatedly making authentication requests to the mirror with the same credentials will not pause expiry of the result from the cache.

This value is in seconds.

A positive value will cache the authentication results for the configured period. If the value is postive and smaller than plugin.mirroring.upstream.auth.cache.expiry it will be adjusted upwards. A non-positive value will disable the cache and cause any failing authentication requests to not attempt recovery using a previously changed result thus failing any related authentication requests by clients. Defaults to half an hour.

plugin.mirroring.upstream.auth.cache.fallback.max

Configures the maximum number of fallback authentication cache entries. Cache entries for Bitbucket Server mirrors can be heavy for certain permission schemes so this setting can control how much memory is devoted to this cache.

For Bitbucket Server mirrors, there is one cache entry consumed for each combination of {user credentials, authentication method (HTTP basic/SSH)}

For bitbucket.org mirrors, there is one cache entry consumed for each combination of {user credentials, authentication method (HTTP basic/SSH), repository}

Maximum number of lines which may be returned from a given file when viewing source. This value breaks large files into multiple pages. This property relates to display.max.source.line in that up to (display.max.source.lines/page.max.source.lines) requests will be made to view the page.

page.max.tags

Maximum number of tags per page.

page.max.users

Maximum number of users per page.

page.scan.pullrequest.activity.size

The page size to use when searching activities to find a specific one.

page.scan.pullrequest.activity.count

The number of pages of activities to scan, when searching for a given activity, before giving up.

password.reset.validity.period

Controls how long a password reset token remains valid for. Default period is 72 hours.

This value is in minutes.

process.timeout.execution

Configures a hard upper limit on how long the command is allowed to run even if it is producing output.

This value is in seconds. Using 0, or a negative value, disables the timeout completely.

process.timeout.idle

The idle timeout configures how long the command is allowed to run without producing any output.

This value is in seconds. Using 0, or a negative value, disables the timeout completely.

atlassian.profile.mintime

Controls the threshold time below which a profiled section should not be reported.

This value is in milliseconds.

atlassian.profile.mintotaltime

Controls the threshold time below which a profiled request should not be reported.

This value is in milliseconds.

pullrequest.suggestions.drift.timeout

Defines the maximum amount of time SCM commands used to drift suggestions back to the source branch are allowed to execute before they are terminated. In most cases a user will be waiting whilst this happens, so we need to balance between applying the suggestion and user experience. If this timeout is exceeded, the user is advised to apply the suggestion manually.

This value is in seconds.

pullrequest.commit.indexing.maximum.commits

Defines the maximum number of commits that will be associated with a pull request when a pull request is created or when new commits are pushed to a pull request. A larger number will impact pull request creation and rescoping time. Pull requests that have more than this number of commits may not appear linked in the commit screen.

pullrequest.commit.indexing.backfill.maximum.processed

Defines the maximum number of pull requests to process at once while backfilling pull request commits. A lower limit will mean less data needs to be stored in memory at once, but processing will take longer as a result.

pullrequest.commit.indexing.backfill.batch.size

Defines the maximum number of pull request commit relationships to commit to the database in a single transaction.

pullrequest.commit.indexing.backfill.process.timeout

Defines the maximum amount of time SCM commands used to backfill pull request commits are allowed to execute before they are terminated.

This value is in seconds.

pullrequest.bulk.rescope.timeout

Defines the maximum amount of time any command used to analyse the effects of ref changes to open pull requests (rescoping) is allowed to execute. For these commands, the standard idle timeout for processes applies.

This value is in seconds

pullrequest.deletion.role

Determines which users can delete pull requests. Valid values are: - AUTHOR pull request authors and repository admins can delete pull requests - REPO_ADMIN repository admins can delete pull requests

pullrequest.diff.context

Defines the number of context lines to include around diff segments in pull request diffs. By default, git only includes 3 lines. The default is 10, to try and include a bit more useful context around changes, until the ability to "expand" the context is implemented.

pullrequest.merge.timeout

Defines the maximum amount of time any command used to merge a pull request is allowed to execute or idle. Since merging a pull request may require a series of different commands at the SCM level, this timeout does not define the upper bound for how long the overall merge process might take; it only defines the duration allotted to any single command.

This value is in seconds.

pullrequest.rescope.commits.display

Defines the maximum number of commits per type (either added or removed) to display in a rescope activity.

pullrequest.rescope.commits.max

Defines the absolute maximum number of commits that will be evaluated when attempting to determine, for a given rescope activity, which commits were added to or removed from a pull request. Adjusting this setting can have significant memory footprint impact on the system. It is not recommended to be changed, but the option is provided here to support unique use cases.

pullrequest.rescope.cleanup.interval

Controls how frequently empty rescope activities are cleaned up. Because pull requests rescope very frequently it is important to remove empty rescopes from the database to keep activity queries performant.

This value is in minutes.

pullrequest.rescope.detail.threads

Defines the maximum number of threads to use for precalculating rescope details. These threads perform the requisite processing to determine the commits added and removed when a pull request is rescoped, where most rescopes do not add or remove any commits. Such "dead" rescopes are deleted during processing. The primary goal is to ensure all details have already been calculated when users try to view a pull request's overview.

pullrequest.rescope.drift.commandtimeout

Defines the maximum amount of time SCM commands used to perform comment drift are allowed to execute before they are terminated. Aggressive timeouts should not be used here. Commands which timeout may result in comments which are still present in the diff being orphaned or drifted incorrectly.

This value is in seconds.

pullrequest.rescope.drift.maxattempts

Controls how many times comment drift will be retried when it fails. Certain failure types are considered to be unrecoverable and will not be retried regardless of this setting. Unrecoverable failures are logged.

pullrequest.rescope.drift.threads

Defines the maximum number of threads to use when processing comment drift for a pull request during rescope. Higher numbers here do not necessarily mean higher throughput! Performing comment drift will usually force a new merge to be created, which can be very I/O intensive. Having a substantial number of merges running at the same time can significantly reduce the speed of performing comment drift.

pullrequest.rescope.threads

Defines the maximum number of threads to use for rescoping pull requests.

plugin.bitbucket-ref-restriction.case.insensitive

Controls whether refs are matched case insensitively for ref restrictions.

plugin.ref-restriction.feature.ascii.art

Controls whether ASCII art is displayed when a push is rejected.

plugin.ref-restriction.feature.splash

Controls whether new users are shown a splash page when first viewing ref restrictions.

plugin.bitbucket-ref-restriction.max.resources

The maximum number of ref restrictions per repository. This count refers to each permission item, not each branch. High numbers of branch permissions will adversely impact the speed of pushes to the repository, so increasing this limit is not recommended.

plugin.bitbucket-ref-restriction.max.resource.entities

The maximum number of access grants per ref restriction.

ref.metadata.timeout

Controls timeouts for retrieving metadata associated with a collection of refs from all metadata providers collectively.

This values is in seconds.

ref.metadata.max.request.count

Maximum number of refs that can be used in a metadata query.

ref.search.boost.branches.max

Maximum number of refs we can guarantee exact and prefix matching in correct ordering

plugin.repository.shortcut.url.scheme.extended.whitelist

The extended whitelist for allowed URL schemes. The URL for a repository shortcut must begin with one of the schemes in the default whitelist or a scheme in this property. Schemes should be comma separated, e.g. 'scheme1:,scheme2:'.

scaling.concurrency

Allows adjusting the scaling factor used. Various other CPU/throttling dependent properties are defined in terms of this setting, so adjusting this value implicitly adjusts those. Some examples:

• event.dispatcher.core.threads

• event.dispatcher.max.threads

• executor.max.threads

• throttle.resource.scm-hosting

The default value, cpu, resolves to the number of detected CPU cores. On hyperthreaded machines, this will be double the amount of physical cores.

throttle.resource.git-lfs

Limits the number of Git LFS file transfer operations which may be running concurrently. This is primarily intended to prevent Git LFS requests from consuming all available connections thereby degrading UI and Git hosting operation. This should be a fraction of the maximum number of concurrent connections permitted by Tomcat.

throttle.resource.git-lfs.timeout

Controls how long threads will wait for Git LFS uploads/downloads to complete when the system is already running the maximum number of concurrent transfers. It is recommended this be set to zero (i.e. don't block) or a few seconds at most. Since waiters still hold a connection, a non-zero wait time defeats the purpose of this throttle.

This value is in seconds.

throttle.resource.mirror-hosting

Limits the number of SCM hosting operations served to mirrors, which may be running concurrently. This limit is intended to protect the system's CPU and memory from being consumed excessively by mirror operations.

Note that dynamic throttling is not supported for mirror hosting operations.

throttle.resource.mirror-hosting.timeout

Controls how long threads will wait for SCM mirrors hosting operations to complete when the system is already running the maximum number of SCM commands.

This value is in seconds.

throttle.resource.scm-command

Limits the number of SCM commands, such as: git diff, git blame, or git rev-list, which may be running concurrently. This limit is intended to prevent the operations which support the UI from preventing push/pull operations from being run.

throttle.resource.scm-command.timeout

Controls how long threads will wait for SCM commands to complete when the system is already running the maximum number of SCM commands.

This value is in seconds.

throttle.resource.scm-hosting.timeout

Controls how long threads will wait for SCM hosting operations to complete when the system is already running the maximum number of SCM hosting operations.

This value is in seconds.

throttle.resource.scm-hosting.strategy

Specifies the strategy for throttling SCM hosting operations. Possible values are 'adaptive' and 'fixed'.

If 'fixed' is specified, throttle.resource.scm-hosting.fixed.limit is used as the fixed upper limit on the number of concurrent hosting operations.

If 'adaptive' is specified, the maximum number of hosting operations will vary between throttle.resource.scm-hosting.adaptive.min and throttle.resource.scm-hosting.adaptive.max based on how many hosting operations the system believes the machine can support in its current state and given past performance.

If any configured adaptive throttling setting is invalid and reverts to a default but this conflicts with other correctly configured or default settings, the throttling strategy will revert to 'fixed'. E.g. this will occur if throttle.resource.scm-hosting.adaptive.min is set to the same value as throttle.resource.scm-hosting.adaptive.max

throttle.resource.scm-hosting.adaptive.limit.min

When the adaptive strategy is enabled for throttling SCM hosting operations, this sets the lower limit on the number of SCM hosting operations, meaning pushes and pulls over HTTP or SSH, which may be running concurrently.

Setting a lower limit provides a way to specify a minimum service level for SCM hosting operations regardless of what the adaptive throttling heuristic believes the machine can handle.

There is limited support for mathematical expressions; +,-,*,/ and () are supported.

throttle.resource.scm-hosting.adaptive.limit.max

When the adaptive strategy is enabled for throttling SCM hosting operations, this sets the upper limit on the number of SCM hosting operations, meaning pushes and pulls over HTTP or SSH, which may be running concurrently. This is intended primarily to prevent pulls, which can be very memory-intensive, from exhausting a server's resources. Note that if the machine does not have sufficient memory to support this default value or an explicitly configured value, a smaller value will be chosen on startup.

Adaptive throttling will vary the total tickets There is limited support for mathematical expressions; +,-,*,/ and () are supported.

throttle.resource.scm-hosting.adaptive.cpu.target

When the adaptive strategy is enabled for throttling SCM hosting operations, this sets the target CPU utilisation for the machine (across all processors) which the system takes into consideration when calculating the current throttling limit.

This value represents a trade-off: higher numbers may boost raw throughput of hosting operations, but at the expense of overall system responsiveness for all users. Increasing the target too high or too low brings diminishing returns.

This must be a value between 0.0 and 1.0 and is a percentage of the total available CPU power across all cores

throttle.resource.scm-hosting.fixed.limit

When the fixed strategy is enabled for throttling SCM hosting operations, this limits the number of SCM hosting operations, meaning pushes and pulls over HTTP or SSH, which may be running concurrently. This is intended primarily to prevent pulls, which can be very memory-intensive, from exhausting a server's resources. There is limited support for mathematical expressions; +,-,*,/ and () are supported.

throttle.resource.scm-refs

Limits the number of ref. advertisement operations, which may be running concurrently. Those are throttled separately from clone operations as they are much more lightweight and much shorter so we can and should allow many more of them running concurrently.

throttle.resource.scm-refs.timeout

Controls how long threads will wait for ref. advertisement operations to complete when the system is already running the maximum number of ref. advertisement operations.

This value is in seconds.

plugin.rest.raw.content.markup.max.size

Controls the maximum allowed file size when downloading a marked-up file through the raw content REST endpoint

This value is in bytes. Default is 5 MiB

plugin.bitbucket-scm-cache.expiry.check.interval

Controls how frequently expired cache entries are invalidated and removed from the cache.

This value is in seconds.

plugin.bitbucket-scm-cache.eviction.hysteresis

When eviction is triggered the amount of disk space requested for eviction is calculated as (eviction.hysteresis + eviction.trigger.free.space - free space under <Bitbucket home directory>/caches)

This value is in bytes.

plugin.bitbucket-scm-cache.eviction.trigger.free.space

Controls the threshold at which eviction is triggered in terms of free space available on disk (specifically under <Bitbucket home directory>/caches)

This value is in bytes.

plugin.bitbucket-scm-cache.minimum.free.space

Controls how much space needs to be available on disk (specifically under <Bitbucket home directory>/caches) for caching to be enabled. This setting ensures that the cache plugin does not fill up the disk.

This value is in bytes.

plugin.bitbucket-scm-cache.protocols

Controls which protocols caching is applied to. The HTTP value includes both http and https.

This property value is a comma-separated list. Valid values are: HTTP and SSH.

plugin.bitbucket-scm-cache.capabilities.enabled

Controls whether git v2 capabilities advertisement is cached.

plugin.bitbucket-scm-cache.capabilities.maxCount

The maximum number of git v2 capabilities advertisement to retain per repository. If there are more than this configured limit, the least recently accessed entry will be invalidated.

plugin.bitbucket-scm-cache.capabilities.ttl

Controls the 'time to live' for git v2 capability advertisement caches.

This value is in seconds.

plugin.bitbucket-scm-cache.upload-pack.enabled

Controls whether caching is enabled for git-upload-pack (clone operations).

plugin.bitbucket-scm-cache.upload-pack.maxCount

The maximum number of upload-pack cache entries to retain per repository. If there are more than this configured limit, the least recently accessed entry will be invalidated.

plugin.bitbucket-scm-cache.upload-pack.ttl

Controls how long the caches for clone operations are kept around when there no changes to the repository.

Caches are automatically invalidated when someone pushes to a repository or when a pull request is merged.

This value is in seconds.

http.cloneurl.includeusername

Controls whether the HTTP clone URL should contain the currently authenticated user's username

http.scmrequest.async.enabled

Controls whether asynchronous process is enabled for HTTP SCM requests. Asynchronous processing can significantly increase the server's ability to service UI users while under heavy HTTP hosting load

http.scmrequest.async.keepalive

Controls how long asynchronous request threads are allowed to idle before they're terminated. Aggressive timeouts may reduce the number of idle threads, but may also reduce the server's ability to respond to load spikes.

This value is in seconds.

http.scmrequest.async.queue

Do not use. This property is deprecated and, as of 7.4.2, 7.5.1 and 7.6.0 (or newer), it no longer does anything.

http.scmrequest.async.threads

Controls how many threads are used to process HTTP SCM requests asynchronously. Asynchronous processing frees up servlet container threads to allow them to handle other requests, like page requests for UI users.

plugin.bitbucket-git.path.executable

Defines the default path to the git executable. On Windows machines, the .exe suffix will be added to the configured value automatically if it is not present. In general, "git" should be an acceptable default for every platform, here, assuming that it will be available in the runtime user's PATH.

With the new path searching performed by DefaultGitBinaryHelper, setting a default value here is unnecessary, as the plugin will quickly discard the value. This is left here purely for documenting how to set an explicit path.

plugin.bitbucket-git.path.libexec

Defines the path to the git libexec directory (containing the git-core directory). This path is hard-coded into the git executable and is used for forking processes like git-http-backend. If this value is set, those processes will be forked directly. This eliminates an unnecessary fork (git -> git-http-backend) and may improve scalability.

plugin.bitbucket-git.author.name.type

Defines whether commits created by the system should use the username (jdoe) or the display name (John Doe) to specify the Git author/committer. By default, the display name will be used.

This value can be either displayname or username.

plugin.bitbucket-git.diff.renames

Defines whether copy and/or rename detection should be performed. By default, both rename and copy detection are performed. Only files modified in the same commit are considered as rename or copy origins, to minimize overhead.

The possible settings are:

• "copy" or "copies"

  Applies --find-copies.

• "rename" or "renames"

  Applies --find-renames.

• "off"

  Disables rename and copy detection.

When using "copy" or "copies", the value may optionally be suffixed with a "+" to use --find-copies-harder. This setting should be used with caution, as it can be very expensive. It considers every file in the repository, even files not modified in the same commit, as possible origins for copies. When copy and/or rename detection is enabled plugin.bitbucket-git.diff.renames.threshold can be used control the similarity index required for a change to be identified as a copy or rename. This configuration can also be applied at the repository level with plugin.stash-scm-git.diff.renames.KEY.slug or at the project level with plugin.stash-scm-git.diff.renames.KEY

plugin.bitbucket-git.diff.renames.threshold

Defines the threshold, as a percentage, for a file to be detected as a rename or a copy. This setting is only applied if copy and/or rename detection is enabled. The default threshold applied is 50% similarity (defined in git itself).

git diff and git diff-tree do not honor 100 (identical files only) for the threshold. They ignore the threshold and apply the default 50% threshold instead. A configured threshold of 100 will be applied as 99. Similarly, a configured threshold that is 0, or negative, will be applied as 1. This configuration can also be applied at the repository level with plugin.stash-scm-git.diff.renames.threshold.KEY.slug or at the project level with plugin.stash-scm-git.diff.renames.threshold.KEY

plugin.bitbucket-git.environment.commandsize

Defines the maximum number of characters that can be added to a single command. Different operating systems (and even different versions of the same operating system) have different hard limitations they apply to command line lengths. This default is intended to be low enough to work on all supported platforms out of the box, but still high enough to be usable. It is configurable in case it proves to be too high on some platform. This default is based on Windows, which has a limit of 32768 characters. Testing on Linux (Ubuntu 12.04 running a 3.2 kernel) found that its limit is at least 32x the limit imposed by Windows.

plugin.bitbucket-git.environment.variablesize

Defines the maximum number of characters that can be added to a single environment variable. Different operating systems (and even different versions of the same operating system) have different hard limitations they apply to environment variables. This default is intended to be low enough to work on all supported platforms out of the box, but still high enough to be usable. It is configurable in case it proves to be too high on some platform.

plugin.bitbucket-git.hosting.http.buffersize

Defines the buffer size in bytes which is used when marshaling data between the git process and the HTTP socket. The default is 8K, with a 1K minimum.

plugin.bitbucket-git.hosting.ssh.buffersize

Defines the buffer size in bytes which is used when marshaling data between the git process and the SSH socket. The default is 4K, with a 1K minimum.

plugin.bitbucket-git.hosting.timeout.execution

Defines the execution timeout for push/pull processes, applying a hard limit to how long the operation is allowed to run even if it is producing output or reading input. The default value is 1 day, with a 5 minute minimum.

This value is in seconds.

plugin.bitbucket-git.hosting.timeout.idle

Defines the idle timeout for push/pull processes, applying a limit to how long the operation is allowed to execute without either producing output or consuming input. The default value is 30 minutes, with a 2 minute minimum.

This value is in seconds.

plugin.bitbucket-git.pullrequest.merge.auto.timeout

Defines the maximum amount of time any command used to calculate a pull request's effective diff, or check for conflicts, is allowed to execute or idle. Because the commands used generally do not produce output there is no separate idle timeout.

This setting is deprecated. Use plugin.bitbucket-git.pullrequest.operation.timeout instead. See the documentation for that property for additional details about what operations this timeout applies to.

This value is in seconds.

plugin.bitbucket-git.pullrequest.operation.timeout

Defines the maximum amount of time any command used to calculate a pull request's effective diff, or check for conflicts, is allowed to execute or idle. Because the commands used generally do not produce output there is no separate idle timeout.

This timeout applies to operations that are run in the background. "Foreground" operations, like showing the file tree or an individual file's diff, do not use this timeout. However, in certain cases, such foreground operations may be blocked if a relevant background operation has not yet completed. For example, if a pull request's effective diff has not been calculated, displaying the file tree will block while the effective diff is calculated.

Using an aggressive timeout here may result in pull requests becoming unviewable. For example, if the system times out calculating a pull request's effective diff, it will not be possible to load the file tree and the pull request cannot be reviewed.

This value is in seconds.

plugin.bitbucket-git.ssh.binary

Defines the SSH binary to use for outgoing SSH commands, i.e. git commands that fetch from or push to external repositories over SSH. This setting does not affect incoming SSH requests.

mail.timeout.connect

Controls the timeout for establishing an SMTP connection.

This value is in seconds.

mail.timeout.send

Controls the timeout for sending an e-mail.

This value is in seconds.

mail.test.timeout.connect

Controls the timeout for establishing a test SMTP connection. Shorter timeouts should be applied for when sending test e-mails, as the test occurs in user time.

This value is in seconds.

mail.test.timeout.send

Controls the timeout for sending a test e-mail. Shorter timeouts should be applied for when sending test e-mails, as the test occurs in user time.

This value is in seconds.

mail.error.pause.log

Controls how frequently messages will go to the standard log file about mail sending errors. All errors are logged to atlassian-bitbucket-mail.log, but warnings will be added to the standard log periodically if there are errors sending messages.

This value is in seconds

mail.error.pause.retry

Controls how long to wait before retrying to send a message if an error occurs.

This value is in seconds

mail.threads

Controls the number of threads to use for sending emails. Higher values may result in higher mail server load, but may also allow the system to work through its internal queue faster.

mail.max.message.size

Controls the maximum allowed size of a single mail message in bytes, which is the sum of the subject and body sizes.

This value is in bytes.

mail.max.queue.size

Controls the maximum allowed size for the mail queue in bytes (any new message will be rejected if the mail queue reaches that size)

This value is in bytes.

mail.max.shutdown.wait

Controls the maximum time to wait for the mail queue to empty on shutdown. Once this time elapses, any mail remaining in the queue will be logged as rejected in the mail log and dropped. A value of 0 or less means no waiting will occur, and all mail in the queue will be dropped on shutdown.

This value is in seconds.

mail.crypto.protocols

Space-separated list of crypto protocols to use when sending encrypted email. This default value is POODLE-safe. Order does not matter - JavaMail always tries the latest supported protocol first. An empty value causes the product to use all protocols supported by the shipped version of JavaMail which may not be be POODLE-safe

mail.crypto.ciphers

Space-separated list of ciphers to use when connecting via SSL or TLS. An empty value causes the product to use all ciphers supported by the JVM

plugin.ssh.port

Sets the port where the application will listen for SSH connections, 7999 by default. This value and the SSH base URL's(plugin.ssh.baseurl) port don't need to match, but they often should match.

plugin.ssh.baseurl

Sets the URL on which SSH is accessible, this is used as the base for SSH clone URLs. If SSH is running on a nonstandard port, the base URL must start with ssh:// or clones will fail because Git won't understand the port correctly.

plugin.ssh.command.timeout.idle

Controls timeouts for all SSH commands, such as those that service git and hg operations over SSH. The idle timeout configures how long the command is allowed to run without writing any output to the client. For SCM commands, the plugin.*.hosting.timeout.idle properties defined above will be applied to the underlying process. The default value is 2 hours.

This values is in seconds.

plugin.ssh.nio.workers

Controls the maximum number of NIO worker threads to process incoming SSH commands. The default value is -1, which will use a dynamic maximum based on the number of CPU cores + 1 (the default for the Apache SSHD library).

plugin.ssh.auth.timeout

Controls the timeout when trying to authenticate the incoming SSH command. If authentication does not complete within this period the SSH command will fail. Using a shorter timeout hastens the rejection SSH commands under heavy load and can help keep open socket/file count down.

This values is in seconds.

plugin.ssh.session.pending-writes.max

Controls the number of pending writes the throttling mechanism will allow SSH sessions. Throttling works as a flow control mechanism to prevent the system from writing too much data to Apache MINA's WriteRequestQueue. This is particularly helpful when clients (such as TortoiseGit) setup session channels with extremely large window sizes (2GBs) which means Apache MINA's own flow control mechanism will not stop the command from writing data.

A default value of 512 means that at any given time the system will only be responsible for, at most, 4 MBs per session (some more data may be written to the queue as part of Apache MINA's own handling of the SSH protocol).

Rate limiting will be applied to any SSH session which establishes a channel with a remote window size larger than ${plugin.ssh.session.pending-writes.max} * 8197 (packet size optimized for Git).

A value of 0 or less effectively disables session io rate limiting.

plugin.ssh.session.max

Controls the maximum number of concurrent SSH sessions allowed. If this property is removed the system will set the limit at 250. If this property is configured below 100 the system will set the limit at 100. Increasing this will result in additional memory usage during peak load and can lead to out-of-memory errors.

plugin.ssh.disabled.ciphers

Controls which default ciphers are disabled when executing all SSH commands. Non existent ciphers are ignored. Names are case sensitive. If you override this property, the default values will NOT be appended, and should be included explicitly.

Example value: arcfour128,3des-cbc

To enable additional ciphers see the KB article Disable default SSH algorithms.

plugin.ssh.disabled.key.exchanges

Controls which default key exchange algorithms are disabled when executing all SSH commands. Non existent key exchange algorithms are ignored. Names are case sensitive. If you override this property, the default values will NOT be appended, and should be included explicitly.

Example value: ecdh-sha2-nistp256,ecdh-sha2-nistp384

To enable additional key exchange algorithms see the KB article Disable default SSH algorithms.

plugin.ssh.disabled.macs

Controls which default macs are disabled when executing all SSH commands. Non existent macs are ignored. Names are case sensitive. If you override this property, the default values will NOT be appended, and should be included explicitly.

Example value: hmac-sha1-96,hmac-md5-96,hmac-md5

To enable additional macs see the KB article Disable default SSH algorithms.

plugin.search.codesearch.indexing.enabled

Controls whether code indexing is enabled. Setting this to false prevents repository content from being indexed going forward. Existing repository content will not be un-indexed automatically.

plugin.search.indexing.event.shutdown.timeout

Controls how long an elasticsearch indexing process is given to complete when Bitbucket is shutting down, before it is stopped forcefully. This value is in seconds.

plugin.search.codesearch.indexing.exclude

Allows configuring strategies for excluding certain repositories from code search indexing. This can be used to reduce disk space requirements for the Elasticsearch index.

Valid values are:

• all-forks excludes all forks from code search indexing

• personal-forks excludes personal forks from code search indexing

• synced-forks excludes forks which have ref synchronization enabled from code search indexing

• undiverged-forks excludes forks from code search indexing which have ref synchronization enabled, and have not had their default branch updated

plugin.search.pageSize.primary

Controls the page size of primary search results (eg. code for code search)

plugin.search.pageSize.secondary

Controls the page size of secondary search results (eg. sidebar PRs/repos/etc)

server.context-path

Controls the context path where the application should be published, / by default.

server.display-name

Controls the application's display name.

server.session.cookie.http-only

Controls whether the session cookie should include an HttpOnly restriction, for those browsers that honor it. HttpOnly is enabled by default.

server.session.cookie.max-age

Controls the value of "Max-Age" attribute in session cookie, for those browsers that honor it. This value is in seconds and the default value is 1209600 seconds i.e. 2 weeks. "Expires" attribute is also set based on this value which is absolute date and time when cookie will expire.

server.session.cookie.name

Controls the name used for the session cookie, which is "BITBUCKETSESSIONID" by default. Note that most servlet containers use "JSESSIONID" by default. That is not used here to facilitate installations where multiple applications have the same hostname (typically via reverse proxying) with distinct context paths. In such a setup, using "JSESSIONID" can result in unexpected behavior where logging into one application logs users out of others.

server.session.timeout

Controls the session's timeout, which defaults to 30 minutes. Session timeout may not result in a user having to login again; they may automatically receive a new session via a separate remember-me token.

This value is in seconds.

server.session.tracking-modes

Controls which mechanisms may be used for tracking sessions. By default, only "cookie" tracking is enabled. Other options are "ssl", to use the SSL session ID, and "url", to append the session ID to the URL after a semi-colon. Multiple values may be specified separated by commas (e.g. "cookie,url")

server.address

Controls the network address the application will bind to, 0.0.0.0 by default.

server.compression.enabled

Controls whether the server will attempt to compress data to reduce network costs. By default, compression is enabled on all HTTP/1.1 connectors.

Note: Compression cannot be used when server.connector-protocol is set to AJP/1.3, and it will be ignored if enabled.

server.compression.excluded-user-agents

Controls the list of user-agents to exclude from compression.

server.compression.mime-types

Controls which MIME types are compressed, when compression is enabled. CSS, HTML, JavaScript and JSON are compressed by default.

server.compression.min-response-size

Controls the minimum response length for the compression to be performed. Only the mime-types specified as part of the server.compression.mime-types will be compressed.

This value is in bytes.

server.connection-timeout

Controls the connection timeout, which defines how long the server will wait for a request after a connection is established.

This value is in milliseconds.

server.connector-protocol

Controls the wire protocol used by the primary connector, which is HTTP/1.1 by default.

The following values are supported: * HTTP/1.1 or org.apache.coyote.http11.Http11NioProtocol (Default): A standard HTTP 1.1 connector, which can be configured with or without SSL. All of the various settings are supported for HTTP 1.1. * AJP/1.3 or org.apache.coyote.ajp.AjpNioProtocol: An AJP connector. Several settings, such as max-http-header-size and all of the compression and SSL settings, are not honored when using AJP.

Apache Portable Runtime (APR) and NIO2-based connectors are not supported and may not be used. Attempting to configure either type will result in the system failing during startup.

server.max-http-header-size

Controls the maximum size of the HTTP message header. When using the default value (0), Tomcat's default limit is applied.

Note: The max HTTP header size cannot be configured when server.connector-protocol is set to AJP/1.3, and it will be ignored if set; server.packet-size may be the property you're looking for instead.

This value is in bytes.

server.max-http-post-size

Maximum size of the HTTP post or put content. When using the default value (0), Tomcat's default limit is honored.

This value is in bytes.

server.packet-size

Controls the AJP packet size. When using the default value (0), Tomcat's default packet size is applied. The minimum value is 8192, and the maximum is 65536. If this property is overridden, the value set should match the max_packet_size directive for mod_jk.

Note: Packet size can only be configured when server.connector-protocol is set to AJP/1.3; otherwise it will be ignored.

This value is in bytes.

server.port

Controls the port where the application will listen for connections, 7990 by default.

server.proxy-name

The proxy name, used to construct proper redirect URLs when a reverse proxy is in use.

server.proxy-port

The proxy port, used to construct proper redirect URLs when a reverse proxy is in use. If a proxy port is not set, but a name is, the connector's port will be used as the default.

server.redirect-port

The redirect port to use when redirecting from non-SSL to SSL. Defaults to 443, the standard SSL port.

server.require-ssl

Require an SSL connection when connecting to the server. Setting this to "true" will automatically redirect insecure connections to the configured "redirect-port" for their connectors.

server.scheme

The connector scheme, either "http" or "https". Defaults to "http" unless "secure" is set to "true"; then it defaults to "https". In general, this property should not need to be set.

Note: The scheme cannot be configured when server.connector-protocol is set to AJP/1.3, and it will be ignored if set.

server.secure

Whether the connector is secured. Note that setting this to "true" does not enable SSL; SSL is enabled using server.ssl.enabled instead. One use case for setting this to "true" is when the system is behind a reverse proxy and SSL is terminated at the proxy.

Note: The secure flag cannot be configured when server.connector-protocol is set to AJP/1.3, and it will be ignored if set.

server.server-header

Controls the value to use for the Server response header.

If empty, which is the default, no header is sent.

server.ssl.ciphers

Controls the supported SSL ciphers for the connector.

This property value is a comma-separated list.

server.ssl.client-auth

Controls whether the client authentication is wanted ("want") or needed ("need"), this setting directly relates to the clientAuth option for Tomcat. Requires a configured trust store.

Default is empty, which corresponds to the Tomcat's default value of false.

server.ssl.enabled

Controls whether SSL is enabled. By default, SSL is disabled and the primary connector uses unsecured HTTP.

Note: SSL cannot be used when the server.connector-protocol is set to AJP/1.3, and attempting to enable it will prevent the server from starting.

server.ssl.key-alias

Controls the alias used when selecting the key to use in the keystore. For compatibility with keys setup for Bitbucket Server 4.x and earlier, the default is "tomcat".

server.ssl.key-password

Controls the password used to access the key within the keystore. (server.ssl.key-store-password is used to control the password for accessing the keystore itself.) For compatibility with keys setup for Bitbucket Server 4.x and earlier, the default is "changeit".

server.ssl.key-store

Controls the location of the keystore, "$BITBUCKET_HOME/shared/config/ssl-keystore" by default.

server.ssl.key-store-password

Controls the password used to access the keystore. (server.ssl.key-password is used to control the password for accessing the specific key within the keystore.) For compatibility with keys setup for Bitbucket Server 4.x and earlier, the default is "changeit".

server.ssl.key-store-type

Controls the keystore type. The JVM's default keystore type as returned by KeyStore.getDefaultType(), typically "jks", is used by default.

server.ssl.enabled-protocols

Controls which SSL protocols the connector will allow when communicating with clients. This value can be a comma-separated list (without spaces) to allow multiple protocols.

Possible values include: * SSLv2Hello * SSLv3 * TLSv1 * TLSv1.1 * TLSv1.2 * TLSv1.3 (Requires a supporting JVM) * all (Default; equivalent to "SSLv2Hello,TLSv1,TLSv1.1,TLSv1.2,TLSv1.3")

Note that SSLv2 and SSLv3 are inherently unsafe and should not be used.

server.ssl.protocol

Controls the SSL protocol the connector will use by default.

To control which protocols are supported, set server.ssl.enabled-protocols instead. Even if the connector defaults to a given protocol, clients can use any enabled protocol.

server.ssl.trust-store

Controls which trust store holds the SSL certificates

server.ssl.trust-store-password

Controls the password to be used to access the trust store.

server.ssl.trust-store-provider

Controls the provider for the trust store.

server.ssl.trust-store-type

Controls the type for the trust store.

server.busy.on.ticket.rejected.within

This value is in minutes. Using 0, or a negative value, disables displaying the banner.

server.busy.on.queue.time

Controls how long requests need to be queued before they cause a warning banner to appear.

This value is in seconds. Using 0, or a negative value, disables displaying the banner.
