9 # @DESCRIPTION:
10 # This eclass provides the generic cvs fetching functions. To use this from an
11 # ebuild, set the ECLASS VARIABLES as specified below in your ebuild before
12 # inheriting. Then either leave the default src_unpack or extend over
13 # cvs_src_unpack. If you find that you need to call the cvs_* functions
14 # directly, I'd be interested to hear about it.

22
23 # Implement more auth types (gserver?, kserver?)
24
25 # Support additional remote shells with `ext' authentication (does
26 # anyone actually need to use it with anything other than SSH?)
27
28
29 # Users shouldn't change these settings! The ebuild/eclass inheriting
30 # this eclass will take care of that. If you want to set the global
31 # KDE cvs ebuilds' settings, see the comments in kde-source.eclass.
32
33 # @ECLASS-VARIABLE: ECVS_CVS_COMPRESS
34 # @DESCRIPTION:

36 # is defined by ebuild/user.

42 # is defined by ebuild/user.

44
45 # @ECLASS-VARIABLE: ECVS_CVS_COMMAND
46 # @DESCRIPTION:
47 # CVS command to run
48 #
49 # You can set, for example, "cvs -t" for extensive debug information
50 # on the cvs connection. The default of "cvs -q -f -z4" means to be
51 # quiet, to disregard the ~/.cvsrc config file and to use maximum
52 # compression.

67 # @DESCRIPTION:
68 # Set this variable to a non-empty value to disable the automatic updating of
69 # a CVS source tree. This is intended to be set outside the cvs source
70 # tree by users.
71 : ${ECVS_OFFLINE:=${EVCS_OFFLINE}}
72
73 # @ECLASS-VARIABLE: ECVS_LOCAL
74 # @DEFAULT_UNSET
75 # @DESCRIPTION:
76 # If this is set, the CVS module will be fetched non-recursively.
77 # Refer to the information in the CVS man page regarding the -l
78 # command option (not the -l global option).
79
80 # @ECLASS-VARIABLE: ECVS_LOCALNAME
81 # @DEFAULT_UNSET
82 # @DESCRIPTION:
83 # Local name of checkout directory
84 #
85 # This is useful if the module on the server is called something
86 # common like 'driver' or is nested deep in a tree, and you don't like
87 # useless empty directories.
88 #
89 # WARNING: Set this only from within ebuilds! If set in your shell or
90 # some such, things will break because the ebuild won't expect it and
91 # have e.g. a wrong $S setting.
92
93 # @ECLASS-VARIABLE: ECVS_TOP_DIR
94 # @DESCRIPTION:
95 # The directory under which CVS modules are checked out.

97
98 # @ECLASS-VARIABLE: ECVS_SERVER
99 # @DESCRIPTION:
100 # CVS path
101 #
102 # The format is "server:/dir", e.g. "anoncvs.kde.org:/home/kde".
103 # Remove the other parts of the full CVSROOT, which might look like
104 # ":pserver:anonymous@anoncvs.kde.org:/home/kde"; this is generated
105 # using other settings also.
106 #
107 # Set this to "offline" to disable fetching (i.e. to assume the module
108 # is already checked out in ECVS_TOP_DIR).
109 [ -z "$ECVS_SERVER" ] && ECVS_SERVER="offline"
110
111 # @ECLASS-VARIABLE: ECVS_MODULE
112 # @REQUIRED
113 # @DESCRIPTION:
114 # The name of the CVS module to be fetched
115 #
116 # This must be set when cvs_src_unpack is called. This can include
117 # several directory levels, i.e. "foo/bar/baz"

120
121 # @ECLASS-VARIABLE: ECVS_BRANCH
122 # @DEFAULT_UNSET
123 # @DESCRIPTION:
124 # The name of the branch/tag to use
125 #
126 # The default is "HEAD". The following default _will_ reset your
127 # branch checkout to head if used.
128
129 #[ -z "$ECVS_BRANCH" ] && ECVS_BRANCH="HEAD"
130
131 # @ECLASS-VARIABLE: ECVS_AUTH
132 # @DESCRIPTION:
133 # Authentication method to use
134 #
135 # Possible values are "pserver" and "ext". If `ext' authentication is
136 # used, the remote shell to use can be specified in CVS_RSH (SSH is
137 # used by default). Currently, the only supported remote shell for
138 # `ext' authentication is SSH.
139 #
140 # Armando Di Cianno <fafhrd@gentoo.org> 2004/09/27
141 # - Added "no" as a server type, which uses no AUTH method, nor
142 # does it login
143 # e.g.
144 # "cvs -danoncvs@savannah.gnu.org:/cvsroot/backbone co System"
145 # ( from gnustep-apps/textedit )

156 [ -z "$ECVS_PASS" ] && ECVS_PASS=""
157
158 # @ECLASS-VARIABLE: ECVS_SSH_HOST_KEY
159 # @DEFAULT_UNSET
160 # @DESCRIPTION:
161 # If SSH is used for `ext' authentication, use this variable to
162 # specify the host key of the remote server. The format of the value
163 # should be the same format that is used for the SSH known hosts file.
164 #
165 # WARNING: If a SSH host key is not specified using this variable, the
166 # remote host key will not be verified.
167
168 # @ECLASS-VARIABLE: ECVS_CLEAN
169 # @DEFAULT_UNSET
170 # @DESCRIPTION:
171 # Set this to get a clean copy when updating (passes the
172 # -C option to cvs update)
173
174 # @ECLASS-VARIABLE: ECVS_RUNAS
175 # @DEFAULT_UNSET
