8 # @BLURB: This eclass provides generic cvs fetching functions
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.

18 # TODO:
19
20 # Implement more auth types (gserver?, kserver?)
21
22 # Support additional remote shells with `ext' authentication (does
23 # anyone actually need to use it with anything other than SSH?)
24
25
26 # Users shouldn't change these settings! The ebuild/eclass inheriting
27 # this eclass will take care of that. If you want to set the global
28 # KDE cvs ebuilds' settings, see the comments in kde-source.eclass.
29
30 # @ECLASS-VARIABLE: ECVS_CVS_COMMAND
31 # @DESCRIPTION:
32 # CVS command to run
33 #
34 # You can set, for example, "cvs -t" for extensive debug information
35 # on the cvs connection. The default of "cvs -q -f -z4" means to be
36 # quiet, to disregard the ~/.cvsrc config file and to use maximum
37 # compression.

41 # @DESCRIPTION:
42 # Set the compression level.
43 [[ -z ${ECVS_CVS_COMPRESS} ]] && ECVS_CVS_COMPRESS="-z1"

53 # won't work.
54 [ -z "$ECVS_UP_OPTS" ] && ECVS_UP_OPTS="-dP"

60
61 # @ECLASS-VARIABLE: ECVS_OFFLINE
62 # @DESCRIPTION:
63 # Set this variable to a non-empty value to disable the automatic updating of
64 # a CVS source tree. This is intended to be set outside the cvs source
65 # tree by users.
66 : ${ECVS_OFFLINE:=${ESCM_OFFLINE}}
67
68 # @ECLASS-VARIABLE: ECVS_LOCAL
69 # @DEFAULT_UNSET
70 # @DESCRIPTION:
71 # If this is set, the CVS module will be fetched non-recursively.
72 # Refer to the information in the CVS man page regarding the -l
73 # command option (not the -l global option).
74
75 # @ECLASS-VARIABLE: ECVS_LOCALNAME
76 # @DEFAULT_UNSET
77 # @DESCRIPTION:
78 # Local name of checkout directory
79 #
80 # This is useful if the module on the server is called something
81 # common like 'driver' or is nested deep in a tree, and you don't like
82 # useless empty directories.
83 #
84 # WARNING: Set this only from within ebuilds! If set in your shell or
85 # some such, things will break because the ebuild won't expect it and
86 # have e.g. a wrong $S setting.
87
88 # @ECLASS-VARIABLE: ECVS_TOP_DIR
89 # @DESCRIPTION:
90 # The directory under which CVS modules are checked out.
91 [ -z "$ECVS_TOP_DIR" ] && ECVS_TOP_DIR="${PORTAGE_ACTUAL_DISTDIR-${DISTDIR}}/cvs-src"
92
93 # @ECLASS-VARIABLE: ECVS_SERVER
94 # @DESCRIPTION:
95 # CVS path
96 #
97 # The format is "server:/dir", e.g. "anoncvs.kde.org:/home/kde".
98 # Remove the other parts of the full CVSROOT, which might look like
99 # ":pserver:anonymous@anoncvs.kde.org:/home/kde"; this is generated
100 # using other settings also.
101 #
102 # Set this to "offline" to disable fetching (i.e. to assume the module
103 # is already checked out in ECVS_TOP_DIR).
104 [ -z "$ECVS_SERVER" ] && ECVS_SERVER="offline"
105
106 # @ECLASS-VARIABLE: ECVS_MODULE
107 # @REQUIRED
108 # @DESCRIPTION:
109 # The name of the CVS module to be fetched
110 #
111 # This must be set when cvs_src_unpack is called. This can include
112 # several directory levels, i.e. "foo/bar/baz"
113
114 #[ -z "$ECVS_MODULE" ] && die "$ECLASS: error: ECVS_MODULE not set, cannot continue"
115
116 # @ECLASS-VARIABLE: ECVS_BRANCH
117 # @DEFAULT_UNSET
118 # @DESCRIPTION:
119 # The name of the branch/tag to use
120 #
121 # The default is "HEAD". The following default _will_ reset your
122 # branch checkout to head if used.
123
124 #[ -z "$ECVS_BRANCH" ] && ECVS_BRANCH="HEAD"
125
126 # @ECLASS-VARIABLE: ECVS_AUTH
127 # @DESCRIPTION:
128 # Authentication method to use
129 #
130 # Possible values are "pserver" and "ext". If `ext' authentication is
131 # used, the remote shell to use can be specified in CVS_RSH (SSH is
132 # used by default). Currently, the only supported remote shell for
133 # `ext' authentication is SSH.
134 #
135 # Armando Di Cianno <fafhrd@gentoo.org> 2004/09/27
136 # - Added "no" as a server type, which uses no AUTH method, nor
137 # does it login
138 # e.g.
139 # "cvs -danoncvs@savannah.gnu.org:/cvsroot/backbone co System"
140 # ( from gnustep-apps/textedit )
141 [ -z "$ECVS_AUTH" ] && ECVS_AUTH="pserver"

145 # Username to use for authentication on the remote server.
146 [ -z "$ECVS_USER" ] && ECVS_USER="anonymous"
147
148 # @ECLASS-VARIABLE: ECVS_PASS
149 # @DESCRIPTION:
150 # Password to use for authentication on the remote server
151 [ -z "$ECVS_PASS" ] && ECVS_PASS=""
152
153 # @ECLASS-VARIABLE: ECVS_SSH_HOST_KEY
154 # @DEFAULT_UNSET
155 # @DESCRIPTION:
156 # If SSH is used for `ext' authentication, use this variable to
157 # specify the host key of the remote server. The format of the value
158 # should be the same format that is used for the SSH known hosts file.
159 #
160 # WARNING: If a SSH host key is not specified using this variable, the
161 # remote host key will not be verified.
162
163 # @ECLASS-VARIABLE: ECVS_CLEAN
164 # @DEFAULT_UNSET
165 # @DESCRIPTION:
166 # Set this to get a clean copy when updating (passes the
167 # -C option to cvs update)
168
169 # @ECLASS-VARIABLE: ECVS_RUNAS
170 # @DEFAULT_UNSET
171 # @DESCRIPTION:

174 # special magic.
