21 .Nd gotd configuration file
24 is the run-time configuration file for
27 The file format is line-based, with one configuration directive per line.
28 Any lines beginning with a
30 are treated as comments and ignored.
31 .Sh GLOBAL CONFIGURATION
32 The available global configuration directives are as follows:
34 .It Ic connection Ar option
35 Set the specified options and limits for connections to the
41 directive may be specified multiple times, and multiple
43 arguments may be specified within curly braces:
45 .Ic connection Brq Ar ...
47 Each option should only be specified once.
48 If a given option is listed multiple times, the last line which sets this
51 Valid connection options are:
53 .It Ic request timeout Ar seconds
54 Specify the inactivity timeout for operations between client and server.
55 If this timeout is exceeded while a Git protocol request is being processed,
56 the request will be aborted and the connection will be terminated.
58 The timeout value may also have a suffix indicating its unit of measure.
59 Supported suffixes are:
61 .Bl -tag -compact -width tenletters
70 The default timeout is 1h (3600 seconds, one hour).
71 This should only be changed if legitimate requests are exceeding the default
72 timeout for some reason, such as the server spending an extraordinary
73 amount of time generating a pack file.
74 .It Ic limit Ic user Ar identity Ar number
75 Limit the maximum amount of concurrent connections by the user with
80 Numeric user IDs are also accepted.
82 The default per-user limit is 4.
83 This should only be changed if concurrent connections from a given user are
84 expected to exceed the default limit, for example if an anonymous user
85 is granted read access and many concurrent connections will share this
86 anonymous user identity.
88 .It Ic listen on Ar path
89 Set the path to the unix socket which
92 If not specified, the path
93 .Pa /var/run/gotd.sock
102 requires root privileges in order to create its unix socket.
105 drops privileges to the specified
107 If not specified, the user _gotd will be used.
109 .Sh REPOSITORY CONFIGURATION
110 At least one repository context must exist for
113 For each repository, access rules must be configured using the
117 configuration directives.
118 Multiple access rules can be specified, and the last matching rule
119 determines the action taken.
120 If no rule matches, access to the repository is denied.
122 A repository context is declared with a unique
124 followed by repository-specific configuration directives inside curly braces:
126 .Ic repository Ar name Brq ...
131 clients can connect to a repository by including the repository's unique
134 Clients appending the string
138 will also be accepted.
142 may contain path-separators,
144 to expose repositories as part of a virtual client-visible directory hierarchy.
146 The available repository configuration directives are as follows:
148 .It Ic deny Ar identity
149 Deny repository access to users with the username
151 Group names may be matched by prepending a colon
155 Numeric IDs are also accepted.
157 Set the path to the Git repository.
159 .It Ic permit Ar mode Ar identity
160 Permit repository access to users with the username
164 argument must be set to either
166 for read-only access,
169 for read-write access.
170 Group names may be matched by prepending a colon
174 Numeric IDs are also accepted.
175 .It Ic protect Brq Ar ...
178 directive may be used to protect branches and tags in a repository
179 from being overwritten by potentially destructive client-side commands,
184 are used to change the history of a branch.
186 To build a set of protected branches and tags, multiple
188 directives may be specified per repository and
191 directive parameters may be specified within curly braces.
195 parameters are as follows:
198 .It Ic branch Ar name
199 Protect the named branch.
200 The branch may be created if it does not exist yet.
201 Attempts to delete the branch or change its history will be denied.

207 it will be looked up in the
210 .It Ic branch Ic namespace Ar namespace
211 Protect the given reference namespace, assuming that references in
212 this namespace represent branches.
213 New branches may be created in the namespace.
214 Attempts to change the history of branches or delete them will be denied.
218 argument must be absolute, starting with
220 .It Ic tag Ic namespace Ar namespace
221 Protect the given reference namespace, assuming that references in
222 this namespace represent tags.
223 New tags may be created in the namespace.
224 Attempts to change or delete existing tags will be denied.
228 argument must be absolute, starting with
232 The special reference namespaces
236 do not need to be listed in
238 These namespaces are always protected and even attempts to create new
239 references in these namespaces will always be denied.
