DESCRIPTION
cvs
is a system for providing source control to hierarchical collections
of source directories. Commands and procedures for using ccvvss
are described in
cvs(1).
cvs
manages _s_o_u_r_c_e _r_e_p_o_s_i_t_o_r_i_e_s, the directories containing master
copies of the revision-controlled files, by copying particular
revisions of the files to (and modifications back from) developers'
private _w_o_r_k_i_n_g _d_i_r_e_c_t_o_r_i_e_s. In terms of file structure, each
individual source repository is an immediate subdirectory of
$$CCVVSSRROOOOTT.
The files described here are supporting files; they do not have to
exist for ccvvss to operate, but they allow you to make ccvvss
operation more flexible.
You can use the `modules' file to define symbolic names for
collections of source maintained with ccvvss. If there is no
`modules' file, developers must specify complete path names
(absolute, or relative to $$CCVVSSRROOOOTT) for the files they wish to
manage with ccvvss commands.
You can use the `commitinfo' file to define programs to execute
whenever `ccvvss ccoommmmiitt' is about to execute.
These programs are used for ``pre-commit'' checking to verify that the
modified, added, and removed files are really ready to be committed.
Some uses for this check might be to turn off a portion (or all) of the
source repository from a particular person or group.
Or, perhaps, to verify that the changed files conform to the site's
standards for coding practice.
You can use the `cvswrappers' file to record
cvs
wrapper commands to be used when checking files into and out of the
repository. Wrappers allow the file or directory to be processed
on the way in and out of CVS. The intended uses are many, one
possible use would be to reformat a C file before the file is checked
in, so all of the code in the repository looks the same.
You can use the `loginfo' file to define programs to execute after
any
commit,
which writes a log entry for changes in the repository.
These logging programs might be used to append the log message to a file.
Or send the log message through electronic mail to a group of developers.
Or, perhaps, post the log message to a particular newsgroup.
You can use the `taginfo' file to define programs to execute after
any
tagorrtag
operation. These programs might be used to append a message to a file
listing the new tag name and the programmer who created it, or send mail
to a group of developers, or, perhaps, post a message to a particular
newsgroup.
You can use the `rcsinfo' file to define forms for log messages.
You can use the `editinfo' file to define a program to execute for
editing/validating `ccvvss ccoommmmiitt' log entries.
This is most useful when used with a `rcsinfo' forms specification, as
it can verify that the proper fields of the form have been filled in by the
user committing the change.
You can use the `cvsignore' file to specify the default list of
files to ignore during uuppddaattee.
You can use the `history' file to record the ccvvss commands
that affect the repository.
The creation of this file enables history logging.
FILES
-
modules
-
The `modules' file records your definitions of names for
collections of source code. ccvvss will use these definitions if
you use ccvvss to check in a file with the right format to
`$$CCVVSSRROOOOTT//CCVVSSRROOOOTT//mmoodduulleess,,vv'.
The `modules' file may contain blank lines and comments (lines
beginning with `##') as well as module definitions.
Long lines can be continued on the next line by specifying a backslash
(``\'') as the last character on the line.
A _m_o_d_u_l_e _d_e_f_i_n_i_t_i_o_n is a single line of the `modules' file,
in either of two formats. In both cases, _m_n_a_m_e represents the
symbolic module name, and the remainder of the line is its definition.
_m_n_a_m_e --aa _a_l_i_a_s_e_s...
This represents the simplest way of defining a module _m_n_a_m_e.
The `--aa' flags the definition as a simple alias: ccvvss
will treat any use of _m_n_a_m_e (as a command argument) as if the list
of names _a_l_i_a_s_e_s had been specified instead. _a_l_i_a_s_e_s may
contain either other module names or paths. When you use paths in
_a_l_i_a_s_e_s, `ccvvss cchheecckkoouutt' creates all intermediate
directories in the working directory, just as if the path had been
specified explicitly in the ccvvss arguments.
_m_n_a_m_e [ _o_p_t_i_o_n_s ] _d_i_r [ _f_i_l_e_s... ] [ &&_m_o_d_u_l_e... ]
In the simplest case, this form of module definition reduces to
`_m_n_a_m_e _d_i_r'. This defines all the files in directory
_d_i_r as module _m_n_a_m_e. _d_i_r is a relative path (from
$$CCVVSSRROOOOTT) to a directory of source in one of the source
repositories. In this case, on cchheecckkoouutt, a single directory
called _m_n_a_m_e is created as a working directory; no intermediate
directory levels are used by default, even if _d_i_r was a path
involving several directory levels.
By explicitly specifying _f_i_l_e_s in the module definition after
_d_i_r, you can select particular files from directory
_d_i_r. The sample definition for mmoodduulleess is an example of
a module defined with a single file from a particular directory. Here
is another example:
mm44tteesstt uunnssuuppppoorrtteedd//ggnnuu//mm44 ffoorreeaacchh..mm44 ffoorrlloooopp..mm44
With this definition, executing `ccvvss cchheecckkoouutt mm44tteesstt'
will create a single working directory `m4test' containing the two
files listed, which both come from a common directory several levels
deep in the ccvvss source repository.
A module definition can refer to other modules by including
`&&_m_o_d_u_l_e' in its definition. cchheecckkoouutt creates
a subdirectory for each such _m_o_d_u_l_e, in your working directory.
New in ccvvss 1.3;
avoid this feature if sharing module definitions with older versions
of ccvvss.
Finally, you can use one or more of the following _o_p_t_i_o_n_s in
module definitions:
`--dd _n_a_m_e', to name the working directory something
other than the module name.
New in ccvvss 1.3;
avoid this feature if sharing module definitions with older versions
of ccvvss.
`--ii _p_r_o_g' allows you to specify a program _p_r_o_g
to run whenever files in a module are committed. _p_r_o_g runs with a
single argument, the full pathname of the affected directory in a
source repository. The `commitinfo', `loginfo', and
`editinfo' files provide other ways to call a program on ccoommmmiitt.
`--oo _p_r_o_g' allows you to specify a program _p_r_o_g
to run whenever files in a module are checked out. _p_r_o_g runs
with a single argument, the module name.
`--ee _p_r_o_g' allows you to specify a program _p_r_o_g
to run whenever files in a module are exported. _p_r_o_g runs
with a single argument, the module name.
`--tt _p_r_o_g' allows you to specify a program _p_r_o_g
to run whenever files in a module are tagged. _p_r_o_g runs with two
arguments: the module name and the symbolic tag specified to rrttaagg.
`--uu _p_r_o_g' allows you to specify a program _p_r_o_g
to run whenever `ccvvss uuppddaattee' is executed from the top-level
directory of the checked-out module. _p_r_o_g runs with a
single argument, the full path to the source repository for this module.
-
ccoommmmiittiinnffoo, llooggiinnffoo, rrccssiinnffoo, eeddiittiinnffoo
-
These files all specify programs to call at different points in the
`ccvvss ccoommmmiitt' process. They have a common structure.
Each line is a pair of fields: a regular expression, separated by
whitespace from a filename or command-line template.
Whenever one of the regular expression matches a directory name in the
repository, the rest of the line is used.
If the line begins with a ## character, the entire line is considered
a comment and is ignored.
Whitespace between the fields is also ignored.
For `loginfo', the rest of the
line is a command-line template to execute.
The templates can include not only
a program name, but whatever list of arguments you wish. If you write
`%%ss' somewhere on the argument list, ccvvss supplies, at
that point, the list of files affected by the ccoommmmiitt.
The first entry in the list is the relative path within the source
repository where the change is being made.
The remaining arguments list the files that are being modified, added, or
removed by this ccoommmmiitt invocation.
For `taginfo', the rest of the
line is a command-line template to execute.
The arguments passed to the command are, in order, the
tagname ,
operation
(i.e.
add
for `tag',
mov
for `tag -F', and
del
for `tag -d`),
repository ,
and any remaining are pairs of
filename revision .
A non-zero exit of the filter program will cause the tag to be aborted.
For `commitinfo', the rest of the line is a command-line template to
execute.
The template can include not only a program name, but whatever
list of arguments you wish.
The full path to the current source repository is appended to the template,
followed by the file names of any files involved in the commit (added,
removed, and modified files).
For `rcsinfo', the rest of the line is the full path to a file that
should be loaded into the log message template.
For `editinfo', the rest of the line is a command-line template to
execute.
The template can include not only a program name, but whatever
list of arguments you wish.
The full path to the current log message template file is appended to the
template.
You can use one of two special strings instead of a regular
expression: `AALLLL' specifies a command line template that
must always be executed, and `DDEEFFAAUULLTT' specifies a command
line template to use if no regular expression is a match.
The `commitinfo' file contains commands to execute _b_e_f_o_r_e any
other ccoommmmiitt activity, to allow you to check any conditions that
must be satisfied before ccoommmmiitt can proceed. The rest of the
ccoommmmiitt will execute only if all selected commands from this file
exit with exit status 00.
The `rcsinfo' file allows you to specify _l_o_g _t_e_m_p_l_a_t_e_s for
the ccoommmmiitt logging session; you can use this to provide a form
to edit when filling out the ccoommmmiitt log. The field after the
regular expression, in this file, contains filenames (of files
containing the logging forms) rather than command templates.
The `editinfo' file allows you to execute a script _b_e_f_o_r_e _t_h_e
_c_o_m_m_i_t _s_t_a_r_t_s, but after the log information is recorded. These
"edit" scripts can verify information recorded in the log file. If
the edit script exits with a non-zero exit status, the commit is aborted.
The `loginfo' file contains commands to execute _a_t _t_h_e _e_n_d
of a commit. The text specified as a commit log message is piped
through the command; typical uses include sending mail, filing an
article in a newsgroup, or appending to a central file.
-
ccvvssiiggnnoorree, ..ccvvssiiggnnoorree
-
The default list of files (or
sh(1)
file name patterns) to ignore during `ccvvss uuppddaattee'.
At startup time, ccvvss loads the compiled in default list of file name
patterns (see
cvs(1)).
Then the per-repository list included in $$CCVVSSRROOOOTT//CCVVSSRROOOOTT//ccvvssiiggnnoorree
is loaded, if it exists.
Then the per-user list is loaded from `$HOME/.cvsignore'.
Finally, as ccvvss traverses through your directories, it will load any
per-directory `.cvsignore' files whenever it finds one.
These per-directory files are only valid for exactly the directory that
contains them, not for any sub-directories.
-
history
-
Create this file in $$CCVVSSRROOOOTT//CCVVSSRROOOOTT to enable history logging
(see the description of `ccvvss hhiissttoorryy').
