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.
15
16 inherit eutils
17
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.
38
39 # @ECLASS-VARIABLE: ECVS_CVS_COMPRESS
40 # @DESCRIPTION:
41 # Set the compression level.
42 [[ -z ${ECVS_CVS_COMPRESS} ]] && ECVS_CVS_COMPRESS="-z1"
43
44 # @ECLASS-VARIABLE: ECVS_CVS_OPTIONS
45 # @DESCRIPTION:
46 # Additional options to the cvs commands.
47 [[ -z ${ECVS_CVS_OPTIONS} ]] && ECVS_CVS_OPTIONS="-q -f"

51 # The cvs command.

53
54 # @ECLASS-VARIABLE: ECVS_UP_OPTS

56 # CVS options given after the cvs update command. Don't remove "-dP" or things
57 # won't work.
58 [ -z "$ECVS_UP_OPTS" ] && ECVS_UP_OPTS="-dP"

62 # CVS options given after the cvs checkout command.
63 [ -z "$ECVS_CO_OPTS" ] && ECVS_CO_OPTS=""
64
65 # @ECLASS-VARIABLE: ECVS_OFFLINE
66 # @DESCRIPTION:
67 # Set this variable to a non-empty value to disable the automatic updating of
68 # a CVS source tree. This is intended to be set outside the cvs source
69 # tree by users.
70 : ${ECVS_OFFLINE:=${ESCM_OFFLINE}}
71
72 # @ECLASS-VARIABLE: ECVS_LOCAL
73 # @DESCRIPTION:
74 # If this is set, the CVS module will be fetched non-recursively.
75 # Refer to the information in the CVS man page regarding the -l
76 # command option (not the -l global option).
77
78 # @ECLASS-VARIABLE: ECVS_LOCALNAME
79 # @DESCRIPTION:
80 # Local name of checkout directory
81 #
82 # This is useful if the module on the server is called something
83 # common like 'driver' or is nested deep in a tree, and you don't like
84 # useless empty directories.
85 #
86 # WARNING: Set this only from within ebuilds! If set in your shell or
87 # some such, things will break because the ebuild won't expect it and
88 # have e.g. a wrong $S setting.
89
90 # @ECLASS-VARIABLE: ECVS_TOP_DIR
91 # @DESCRIPTION:
92 # The directory under which CVS modules are checked out.
93 [ -z "$ECVS_TOP_DIR" ] && ECVS_TOP_DIR="${PORTAGE_ACTUAL_DISTDIR-${DISTDIR}}/cvs-src"
94
95 # @ECLASS-VARIABLE: ECVS_SERVER
96 # @DESCRIPTION:
97 # CVS path
98 #
99 # The format is "server:/dir", e.g. "anoncvs.kde.org:/home/kde".
100 # Remove the other parts of the full CVSROOT, which might look like
101 # ":pserver:anonymous@anoncvs.kde.org:/home/kde"; this is generated
102 # using other settings also.
103 #
104 # Set this to "offline" to disable fetching (i.e. to assume the module
105 # is already checked out in ECVS_TOP_DIR).
106 [ -z "$ECVS_SERVER" ] && ECVS_SERVER="offline"
107
108 # @ECLASS-VARIABLE: ECVS_MODULE
109 # @DESCRIPTION:
110 # The name of the CVS module to be fetched
111 #
112 # This must be set when cvs_src_unpack is called. This can include
113 # several directory levels, i.e. "foo/bar/baz"
114
115 #[ -z "$ECVS_MODULE" ] && die "$ECLASS: error: ECVS_MODULE not set, cannot continue"
116
117 # @ECLASS-VARIABLE: ECVS_BRANCH
118 # @DESCRIPTION:
119 # The name of the branch/tag to use
120 #
121 # The default is "HEAD". The following default _will_ reset your
122 # branch checkout to head if used.
123
124 #[ -z "$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"

144 # @DESCRIPTION:
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 # @DESCRIPTION:
155 # If SSH is used for `ext' authentication, use this variable to
156 # specify the host key of the remote server. The format of the value
157 # should be the same format that is used for the SSH known hosts file.
158 #
159 # WARNING: If a SSH host key is not specified using this variable, the
160 # remote host key will not be verified.
161
162 # @ECLASS-VARIABLE: ECVS_CLEAN
163 # @DESCRIPTION:
164 # Set this to get a clean copy when updating (passes the
165 # -C option to cvs update)
166
167 # @ECLASS-VARIABLE: ECVS_RUNAS
168 # @DESCRIPTION:
169 # Specifies an alternate (non-root) user to use to run cvs. Currently
170 # b0rked and wouldn't work with portage userpriv anyway without
171 # special magic.
