File: cvs.info, Node: release output, Next: release examples, Prev: release options, Up: release release output -------------- Before `release' releases your sources it will print a one-line message for any file that is not up-to-date. *Warning:* Any new directories that you have created, but not added to the CVS directory hierarchy with the `add' command (*note add::.) will be silently ignored (and deleted, if `-d' is specified), even if they contain files. `U FILE' There exists a newer revision of this file in the repository, and you have not modified your local copy of the file. `A FILE' The file has been added to your private copy of the sources, but has not yet been committed to the repository. If you delete your copy of the sources this file will be lost. `R FILE' The file has been removed from your private copy of the sources, but has not yet been removed from the repository, since you have not yet committed the removal. *Note commit::. `M FILE' The file is modified in your working directory. There might also be a newer revision inside the repository. `? FILE' FILE is in your working directory, but does not correspond to anything in the source repository, and is not in the list of files for CVS to ignore (see the description of the `-I' option, and *note cvsignore::.). If you remove your working sources, this file will be lost. Note that no warning message like this is printed for spurious directories that CVS encounters. The directory, and all its contents, are silently ignored.  File: cvs.info, Node: release examples, Prev: release output, Up: release release examples ---------------- Release the module, and delete your local working copy of the files. $ cd .. # You must stand immediately above the # sources when you issue `cvs release'. $ cvs release -d tc You have [0] altered files in this repository.

Like most CVS commands, `cvs remove' works on files in your working directory, not directly on the repository. As a safeguard, it also requires that you first erase the specified files from your working directory. The files are not actually removed until you apply your changes to the repository with `commit'; at that point, the corresponding RCS files in the source repository are moved into the `Attic' directory (also within the source repository). This command is recursive by default, scheduling all physically removed files that it finds for removal by the next commit. Use the `-l' option to avoid this recursion, or just specify the actual files that you wish removed. * Menu: * remove options:: remove options * remove examples:: remove examples  File: cvs.info, Node: remove options, Next: remove examples, Up: remove remove options -------------- Two of the standard options are the only options supported by `remove'. `-l' Local; run only in current working directory. `-R' Commit directories recursively. This is on by default.

Use `tag' instead (*note tag::.), to base the selection of revisions on the contents of your working directory. If you attempt to use a tag name that already exists, CVS will complain and not overwrite that tag. Use the `-F' option to force the new tag value. * Menu: * rtag options:: rtag options  File: cvs.info, Node: rtag options, Up: rtag rtag options ------------ These standard options are supported by `rtag' (*note Common options::., for a complete description of them): `-D DATE' Tag the most recent revision no later than DATE. `-f' Only useful with the `-D DATE' or `-r TAG' flags. If no matching revision is found, use the most recent revision (instead of ignoring the file). `-F' Overwrite an existing tag of the same name on a different revision. This option is new in CVS 1.4. The old behavior is matched by `cvs tag -F'. `-l' Local; run only in current working directory. `-n' Do not run any tag program that was specified with the `-t' flag inside the `modules' file. (*note modules::.). `-R' Commit directories recursively. This is on by default. `-r TAG' Only tag those files that contain TAG. This can be used to rename a tag: tag only the files identified by the old tag, then delete the old tag, leaving the new tag on exactly the same files as the old tag. In addition to the above common options, these options are available: `-a' Use the `-a' option to have `rtag' look in the `Attic' (*note Removing files::.) for removed files that contain the specified tag. The tag is removed from these files, which makes it convenient to re-use a symbolic tag as development continues (and files get removed from the up-coming distribution). `-b' Make the tag a branch tag. *Note Branches::. `-d' Delete the tag instead of creating it. In general, tags (often the symbolic names of software distributions) should not be removed, but the `-d' option is available as a means to remove completely obsolete symbolic names if necessary (as might be the case for an Alpha release, or if you mistagged a module).  File: cvs.info, Node: status, Next: tag, Prev: rtag, Up: Invoking CVS status--Status info on the revisions ==================================== * status [-lR] [-v] [files...] * Requires: working directory, repository. * Changes: nothing. Display a brief report on the current status of files with respect to the source repository, including any sticky tags, dates, or `-k' options. You can also use this command to determine the potential impact of a `cvs update' on your working source directory--but remember that things might change in the repository before you run `update'. * Menu: * status options:: status options  File: cvs.info, Node: status options, Up: status status options -------------- These standard options are supported by `status' (*note Common options::., for a complete description of them): `-l' Local; run only in current working directory. `-R' Commit directories recursively. This is on by default. There is one additional option: `-v' Verbose. In addition to the information normally displayed, print all symbolic tags, together with the numerical value of the revision or branch they refer to.  File: cvs.info, Node: tag, Next: update, Prev: status, Up: Invoking CVS tag--Add a symbolic tag to checked out version of RCS file ========================================================== * tag [-lQqR] [-b] [-d] symbolic_tag [files...] * Requires: working directory, repository. * Changes: repository. * Synonym: freeze Use this command to assign symbolic tags to the nearest repository versions to your working sources. The tags are applied immediately to the repository, as with `rtag', but the versions are supplied implicitly by the CVS records of your working files' history rather than applied explicitly. One use for tags is to record a snapshot of the current sources when the software freeze date of a project arrives. As bugs are fixed after the freeze date, only those changed sources that are to be part of the release need be re-tagged. The symbolic tags are meant to permanently record which revisions of which files were used in creating a software distribution. The `checkout' and `update' commands allow you to extract an exact copy of a tagged release at any time in the future, regardless of whether files have been changed, added, or removed since the release was tagged. This command can also be used to delete a symbolic tag, or to create a branch. See the options section below. If you attempt to use a tag name that already exists, CVS will complain and not overwrite that tag. Use the `-F' option to force the new tag value. * Menu: * tag options:: tag options  File: cvs.info, Node: tag options, Up: tag tag options ----------- These standard options are supported by `tag' (*note Common options::., for a complete description of them): `-F' Overwrite an existing tag of the same name on a different revision. This option is new in CVS 1.4. The old behavior is matched by `cvs tag -F'. `-l' Local; run only in current working directory. `-R' Commit directories recursively. This is on by default. Two special options are available: `-b' The -b option makes the tag a branch tag (*note Branches::.), allowing concurrent, isolated development. This is most useful for creating a patch to a previously released software distribution. `-d' Delete a tag. If you use `cvs tag -d symbolic_tag', the symbolic tag you specify is deleted instead of being added. Warning: Be very certain of your ground before you delete a tag; doing this permanently discards some historical information, which may later turn out to be valuable.  File: cvs.info, Node: update, Prev: tag, Up: Invoking CVS update--Bring work tree in sync with repository =============================================== * update [-AdflPpQqR] [-d] [-r tag|-D date] files... * Requires: repository, working directory. * Changes: working directory. After you've run checkout to create your private copy of source from the common repository, other developers will continue changing the central source. From time to time, when it is convenient in your development process, you can use the `update' command from within your working directory to reconcile your work with any revisions applied to the source repository since your last checkout or update. * Menu: * update options:: update options * update output:: update output * update examples:: update examples  File: cvs.info, Node: update options, Next: update output, Up: update update options -------------- These standard options are available with `update' (*note Common options::., for a complete description of them): `-D date' Use the most recent revision no later than DATE. This option is sticky, and implies `-P'. `-f' Only useful with the `-D DATE' or `-r TAG' flags. If no matching revision is found, retrieve the most recent revision (instead of ignoring the file). `-k KFLAG' Process RCS keywords according to KFLAG. See co(1). This option is sticky; future updates of this file in this working directory will use the same KFLAG. The `status' command can be viewed to see the sticky options. *Note status::. `-l' Local; run only in current working directory. `-P' Prune empty directories. `-p' Pipe files to the standard output. `-R' Commit directories recursively. This is on by default. `-r tag' Retrieve revision TAG. This option is sticky, and implies `-P'. These special options are also available with `update'. `-A' Reset any sticky tags, dates, or `-k' options. (If you get a working copy of a file by using one of the `-r', `-D', or `-k' options, CVS remembers the corresponding tag, date, or KFLAG and continues using it on future updates; use the `-A' option to make CVS forget these specifications, and retrieve the head revision of the file). `-d' Create any directories that exist in the repository if they're missing from the working directory. Normally, `update' acts only on directories and files that were already enrolled in your working directory. This is useful for updating directories that were created in the repository since the initial checkout; but it has an unfortunate side effect. If you deliberately avoided certain directories in the repository when you created your working directory (either through use of a module name or by listing explicitly the files and directories you wanted on the command line), then updating with `-d' will create those directories, which may not be what you want. `-I NAME' Ignore files whose names match NAME (in your working directory) during the update. You can specify `-I' more than once on the command line to specify several files to ignore. By default, `update' ignores files whose names match any of the following: RCSLOG RCS SCCS CVS* cvslog.* tags TAGS .make.state .nse_depinfo *~ #* .#* ,* *.old *.bak *.BAK *.orig *.rej .del-* *.a *.o *.so *.Z *.elc *.ln core Use `-I !' to avoid ignoring any files at all. *Note cvsignore::, for other ways to make CVS ignore some files. `-WSPEC' Specify file names that should be filtered during update. You can use this option repeatedly. SPEC can be a file name pattern of the same type that you can specify in the `.cvswrappers' file. *Note Wrappers::. `-jBRANCH' Merge the changes made between the resulting revision and the revision that it is based on (e.g., if the tag refers to a branch, CVS will merge all changes made in that branch into your working file). With two `-j' options, CVS will merge in the changes between the two respective revisions. This can be used to remove a certain delta from your working file; if the file `foo.c' is based on revision 1.6 and you want to remove the changes made between 1.3 and 1.5, you might do: $ cvs update -j1.5 -j1.3 foo.c # note the order... In addition, each -j option can contain an optional date specification which, when used with branches, can limit the chosen revision to one within a specific date. An optional date is specified by adding a colon (:) to the tag: `-jSYMBOLIC_TAG:DATE_SPECIFIER'.  File: cvs.info, Node: update output, Next: update examples, Prev: update options, Up: update update output ------------- `update' keeps you informed of its progress by printing a line for each file, preceded by one character indicating the status of the file: `U FILE' The file was brought up to date with respect to the repository. This is done for any file that exists in the repository but not in your source, and for files that you haven't changed but are not the most recent versions available in the repository. `A FILE' The file has been added to your private copy of the sources, and will be added to the source repository when you run `commit' on the file. This is a reminder to you that the file needs to be committed. `R FILE' The file has been removed from your private copy of the sources, and will be removed from the source repository when you run `commit' on the file. This is a reminder to you that the file needs to be committed. `M FILE' The file is modified in your working directory. `M' can indicate one of two states for a file you're working on: either there were no modifications to the same file in the repository, so that your file remains as you last saw it; or there were modifications in the repository as well as in your copy, but they were merged successfully, without conflict, in your working directory. CVS will print some messages if it merges your work, and a backup copy of your working file (as it looked before you ran `update') will be made. The exact name of that file is printed while `update' runs. `C FILE' A conflict was detected while trying to merge your changes to FILE with changes from the source repository. FILE (the copy in your working directory) is now the output of the rcsmerge(1) command on the two revisions; an unmodified copy of your file is also in your working directory, with the name `.#FILE.REVISION' where REVISION is the RCS revision that your modified file started from. (Note that some systems automatically purge files that begin with `.#' if they have not been accessed for a few days. If you intend to keep a copy of your original file, it is a very good idea to rename it.) `? FILE' FILE is in your working directory, but does not correspond to anything in the source repository, and is not in the list of files for CVS to ignore (see the description of the `-I' option, and *note cvsignore::.). Note that no warning message like this is printed for spurious directories that CVS encounters. The directory, and all its contents, are silently ignored.  File: cvs.info, Node: update examples, Prev: update output, Up: update update examples --------------- The following line will display all files which are not up-to-date without actually change anything in your working directory. It can be used to check what has been going on with the project. $ cvs -n -q update  File: cvs.info, Node: Administrative files, Next: Environment variables, Prev: Invoking CVS, Up: Top Reference manual for the Administrative files ********************************************* Inside the repository, in the directory `$CVSROOT/CVSROOT', there are a number of supportive files for CVS. You can use CVS in a limited fashion without any of them, but if they are set up properly they can help make life easier. The most important of these files is the `modules' file, which defines the modules inside the repository. * Menu: * modules:: Defining modules * Wrappers:: Treat directories as files * commit files:: The commit support files * commitinfo:: Pre-commit checking * editinfo:: Specifying how log messages are created * loginfo:: Where should log messages be sent? * rcsinfo:: Templates for the log messages * cvsignore:: Ignoring files via cvsignore * history file:: History information * Setting up:: Setting up the repository  File: cvs.info, Node: modules, Next: Wrappers, Up: Administrative files The modules file ================ The `modules' file records your definitions of names for collections of source code. CVS will use these definitions if you create a file with the right format in `$CVSROOT/CVSROOT/modules,v'. The mkmodules(1) command should be run whenever the modules file changes, so that the appropriate files can be generated (depending on how you have configured CVS operation). To allow convenient editing of the `modules' file itself, the file should include an entry like the following (where LOCALBIN represents the directory where your site installs programs like mkmodules(1)): modules -i /LOCALBIN/mkmodules CVSROOT modules This defines the name `modules' as the module name for the file itself, so that you can use $ cvs checkout modules to get a copy of the file that you can edit. You should define similar module entries for the other configuration files described in this appendix, except `history'). 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 module definition is a single line of the `modules' file, in either of two formats. In both cases, MNAME represents the symbolic module name, and the remainder of the line is its definition. `MNAME -a ALIASES...' This represents the simplest way of defining a module MNAME. The `-a' flags the definition as a simple alias: CVS will treat any use of MNAME (as a command argument) as if the list of names ALIASES had been specified instead. ALIASES may contain either other module names or paths. When you use paths in aliases, `checkout' creates all intermediate directories in the working directory, just as if the path had been specified explicitly in the CVS arguments. `MNAME [ options ] DIR [ FILES... ] [ &MODULE... ]' In the simplest case, this form of module definition reduces to `MNAME DIR'. This defines all the files in directory DIR as module mname. DIR is a relative path (from `$CVSROOT') to a directory of source in the source repository. In this case, on checkout, a single directory called MNAME is created as a working directory; no intermediate directory levels are used by default, even if DIR was a path involving several directory levels. By explicitly specifying files in the module definition after DIR, you can select particular files from directory DIR. The sample definition for `modules' is an example of a module defined with a single file from a particular directory. Here is another example: m4test unsupported/gnu/m4 foreach.m4 forloop.m4 With this definition, executing `cvs checkout m4test' will create a single working directory `m4test' containing the two files listed, which both come from a common directory several levels deep in the CVS source repository. A module definition can refer to other modules by including `&MODULE' in its definition. `checkout' creates a subdirectory for each such module, in your working directory. `-d NAME' Name the working directory something other than the module name. `-i PROG' Specify a program PROG to run whenever files in a module are committed. PROG 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 commit. `-o PROG' Specify a program PROG to run whenever files in a module are checked out. PROG runs with a single argument, the module name. `-s STATUS' Assign a status to the module. When the module file is printed with `cvs checkout -s' the modules are sorted according to primarily module status, and secondarily according to the module name. This option has no other meaning. You can use this option for several things besides status: for instance, list the person that is responsible for this module. `-t PROG' Specify a program PROG to run whenever files in a module are tagged with `rtag'. PROG runs with two arguments: the module name and the symbolic tag specified to `rtag'. There is no way to specify a program to run when `tag' is executed. `-u PROG' Specify a program PROG to run whenever `cvs update' is executed from the top-level directory of the checked-out module. PROG runs with a single argument, the full path to the source repository for this module.  File: cvs.info, Node: Wrappers, Next: commit files, Prev: modules, Up: Administrative files The cvswrappers file ==================== Wrappers are essentially directories that are to be treated as "files." This package allows such wrappers to be "processed" on the way in and out of CVS. The intended use is to wrap up a wrapper into a single tar, such that that tar can be treated as a single binary file in CVS. Apparently this is particularly useful on NEXTSTEP. To solve the problem effectively, it was also necessary to be able to prevent rcsmerge application at appropriate times. The file `cvswrappers' defines the script that will be run on a file when its name matches a regular expresion. There are two scripts that can be run on a file or directory. A script to filter the directory/file before it gets checked in and another that is run when the file/directory gets checked out. The `cvswrappers' also specifies the merge methodology that should be used when the file is updated, that is should a MERGE or a straight COPY of the diferences be used when checking into the repository. The basic format of the file `cvswrappers' is given as such: wildcard [option value][option value]... where option is one of -f from cvs filter value: path tofilter -t to cvs filter value: path to filter -m update methodology value: MERGE or COPY and value is a single-quote delimited value. *.nib -f 'uncom %s' -t 'comb %s %s' -m 'COPY' *.rtfd -f 'uncom %s' -t 'comb %s %s' -m 'COPY' The above example of a `cvswrappers' file states that all files/directories that end with a `.nib' should be filtered with the `comb' program before checking the file into the repository. The file should be filtered though the `uncom' program when the file is checked out of the repository. The `cvswrappers' file also states that a `COPY' methodology should be used when updating the files in the repository (that is no merging should be performed). The `comb' filter is called with two arguments, the first is the name of the file/directory to filter and the second is the pathname to where the resulting filtered file should be placed. The `uncom' filter is called with one argument, which is the name of the file to filter from. The end result of the `uncom' filter will be a file/directory in the users current working directory, that represents the source before being filtered.  File: cvs.info, Node: commit files, Next: commitinfo, Prev: Wrappers, Up: Administrative files The commit support files ======================== The `-i' flag in the `modules' file can be used to run a certain program whenever files are committed (*note modules::.). The files described in this section provide other, more flexible, ways to run programs whenever something is committed. There are three kind of programs that can be run on commit. They are specified in files in the repository, as described below. The following table summarizes the file names and the purpose of the corresponding programs. `commitinfo' The program is responsible for checking that the commit is allowed. If it exits with a non-zero exit status the commit will be aborted. `editinfo' The specified program is used to edit the log message, and possibly verify that it contains all required fields. This is most useful in combination with the `rcsinfo' file, which can hold a log message template (*note rcsinfo::.). `loginfo' The specified program is called when the commit is complete. It receives the log message and some additional information and can store the log message in a file, or mail it to appropriate persons, or maybe post it to a local newsgroup, or... Your imagination is the limit! * Menu: * syntax:: The common syntax  File: cvs.info, Node: syntax, Up: commit files The common syntax ----------------- The four files `commitinfo', `loginfo', `rcsinfo' and `editinfo' all have a common format. The purpose of the files are described later on. The common syntax is described here. Each line contains the following: * A regular expression * A whitespace separator--one or more spaces and/or tabs. * A file name or command-line template. Blank lines are ignored. Lines that start with the character `#' are treated as comments. Long lines unfortunately can *not* be broken in two parts in any way. The first regular expression that matches the current directory name in the repository is used. The rest of the line is used as a file name or command-line as appropriate.  File: cvs.info, Node: commitinfo, Next: editinfo, Prev: commit files, Up: Administrative files Commitinfo ========== The `commitinfo' file defines programs to execute whenever `cvs commit' 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. This could be used, for instance, to verify that the changed files conform to to your site's standards for coding practice. As mentioned earlier, each line in the `commitinfo' file consists of a regular expression and a command-line template. The template can include a program name and any number of arguments you wish to supply to it. 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). The first line with a regular expression matching the relative path to the module will be used. If the command returns a non-zero exit status the commit will be aborted. If the repository name does not match any of the regular expressions in this file, the `DEFAULT' line is used, if it is specified. All occurances of the name `ALL' appearing as a regular expression are used in addition to the first matching regular expression or the name `DEFAULT'. Note: when CVS is accessing a remote repository, `commitinfo' will be run on the *remote* (i.e., server) side, not the client side (*note Remote repositories::.).  File: cvs.info, Node: editinfo, Next: loginfo, Prev: commitinfo, Up: Administrative files Editinfo ======== If you want to make sure that all log messages look the same way, you can use the `editinfo' file to specify a program that is used to edit the log message. This program could be a custom-made editor that always enforces a certain style of the log message, or maybe a simple shell script that calls an editor, and checks that the entered message contains the required fields. If no matching line is found in the `editinfo' file, the editor specified in the environment variable `$CVSEDITOR' is used instead. If that variable is not set, then the environment variable `$EDITOR' is used instead. If that variable is not set a precompiled default, normally `vi', will be used. The `editinfo' file is often most useful together with the `rcsinfo' file, which can be used to specify a log message template. Each line in the `editinfo' file consists of a regular expression and a command-line template. The template must include a program name, and can include any number of arguments. The full path to the current log message template file is appended to the template. One thing that should be noted is that the `ALL' keyword is not supported. If more than one matching line is found, the first one is used. This can be useful for specifying a default edit script in a module, and then overriding it in a subdirectory. If the repository name does not match any of the regular expressions in this file, the `DEFAULT' line is used, if it is specified. If the edit script exits with a non-zero exit status, the commit is aborted. Note: when CVS is accessing a remote repository, `editinfo' will be run on the *remote* (i.e., server) side, not the client side (*note Remote repositories::.). * Menu: * editinfo example:: Editinfo example  File: cvs.info, Node: editinfo example, Up: editinfo Editinfo example ---------------- The following is a little silly example of a `editinfo' file, together with the corresponding `rcsinfo' file, the log message template and an editor script. We begin with the log message template. We want to always record a bug-id number on the first line of the log message. The rest of log message is free text. The following template is found in the file `/usr/cvssupport/tc.template'. BugId: The script `/usr/cvssupport/bugid.edit' is used to edit the log message. #!/bin/sh # # bugid.edit filename # # Call $EDITOR on FILENAME, and verify that the # resulting file contains a valid bugid on the first # line. if [ "x$EDITOR" = "x" ]; then EDITOR=vi; fi if [ "x$CVSEDITOR" = "x" ]; then CVSEDITOR=$EDITOR; fi $CVSEDITOR $1 until head -1|grep '^BugId:[ ]*[0-9][0-9]*$' < $1 do echo -n "No BugId found. Edit again? ([y]/n)" read ans case ${ans} in n*) exit 1;; esac $CVSEDITOR $1 done The `editinfo' file contains this line: ^tc /usr/cvssupport/bugid.edit The `rcsinfo' file contains this line: ^tc /usr/cvssupport/tc.template  File: cvs.info, Node: loginfo, Next: rcsinfo, Prev: editinfo, Up: Administrative files Loginfo ======= The `loginfo' file is used to control where `cvs commit' log information is sent. The first entry on a line is a regular expression which is tested against the directory that the change is being made to, relative to the `$CVSROOT'. If a match is found, then the remainder of the line is a filter program that should expect log information on its standard input. The filter program may use one and only one % modifier (a la printf). If `%s' is specified in the filter program, a brief title is included (enclosed in single quotes) showing the modified file names. If the repository name does not match any of the regular expressions in this file, the `DEFAULT' line is used, if it is specified. All occurances of the name `ALL' appearing as a regular expression are used in addition to the first matching regular expression or `DEFAULT'. The first matching regular expression is used. *Note commit files::, for a description of the syntax of the `loginfo' file. Note: when CVS is accessing a remote repository, `loginfo' will be run on the *remote* (i.e., server) side, not the client side (*note Remote repositories::.). * Menu: * loginfo example:: Loginfo example  File: cvs.info, Node: loginfo example, Up: loginfo Loginfo example --------------- The following `loginfo' file, together with the tiny shell-script below, appends all log messages to the file `$CVSROOT/CVSROOT/commitlog', and any commits to the administrative files (inside the `CVSROOT' directory) are also logged in `/usr/adm/cvsroot-log' and mailed to ceder. ALL /usr/local/bin/cvs-log $CVSROOT/CVSROOT/commitlog ^CVSROOT Mail -s %s ceder ^CVSROOT /usr/local/bin/cvs-log /usr/adm/cvsroot-log The shell-script `/usr/local/bin/cvs-log' looks like this: #!/bin/sh (echo "-----------------------------------------------------------------"; echo -n $USER" "; date; echo; sed '1s+'${CVSROOT}'++') >> $1  File: cvs.info, Node: rcsinfo, Next: cvsignore, Prev: loginfo, Up: Administrative files Rcsinfo ======= The `rcsinfo' file can be used to specify a form to edit when filling out the commit log. The `rcsinfo' file has a syntax similar to the `editinfo', `commitinfo' and `loginfo' files. *Note syntax::. Unlike the other files the second part is *not* a command-line template. Instead, the part after the regular expression should be a full pathname to a file containing the log message template. If the repository name does not match any of the regular expressions in this file, the `DEFAULT' line is used, if it is specified. All occurances of the name `ALL' appearing as a regular expression are used in addition to the first matching regular expression or `DEFAULT'. The log message template will be used as a default log message. If you specify a log message with `cvs commit -m MESSAGE' or `cvs commit -f FILE' that log message will override the template. *Note editinfo example::, for an example `rcsinfo' file. Note: when CVS is accessing a remote repository, `rcsinfo' will be run on the *remote* (i.e., server) side, not the client side (*note Remote repositories::.).  File: cvs.info, Node: cvsignore, Next: history file, Prev: rcsinfo, Up: Administrative files Ignoring files via cvsignore ============================ There are certain file names that frequently occur inside your working copy, but that you don't want to put under CVS control. Examples are all the object files that you get while you compile your sources. Normally, when you run `cvs update', it prints a line for each file it encounters that it doesn't know about (*note update output::.). CVS has a list of files (or sh(1) file name patterns) that it should ignore while running `update', `import' and `release'. This list is constructed in the following way. * The list is initialized to the following file name patterns: RCSLOG RCS SCCS CVS* cvslog.* tags TAGS .make.state .nse_depinfo *~ #* .#* ,* *.old *.bak *.BAK *.orig *.rej .del-* *.a *.o *.so *.Z *.elc *.ln core * The per-repository list in `$CVSROOT/CVSROOT/cvsignore' is appended to the list, if that file exists. * The per-user list in `.cvsignore' in your home directory is appended to the list, if it exists. * Any entries in the environment variable `$CVSIGNORE' is appended to the list. * Any `-I' options given to CVS is appended. * As CVS traverses through your directories, the contents of any `.cvsignore' will be appended to the list. The patterns found in `.cvsignore' are only valid for the directory that contains them, not for any sub-directories. In any of the 5 places listed above, a single exclamation mark (`!') clears the ignore list. This can be used if you want to store any file which normally is ignored by CVS.  File: cvs.info, Node: history file, Next: Setting up, Prev: cvsignore, Up: Administrative files The history file ================ The file `$CVSROOT/CVSROOT/history' is used to log information for the `history' command (*note history::.). This file must be created to turn on logging. This is done automatically if the `cvsinit' script is used to set up the repository. The file format of the `history' file is unfortunately not yet documented anywhere, but it is fairly easy to understand most of it.  File: cvs.info, Node: Setting up, Prev: history file, Up: Administrative files Setting up the repository ========================= When you install CVS for the first time, you should follow the instructions in the `INSTALL' file to set up the repository. If you want to set up another repository, the easiest way to get a reasonable set of working administrative files is to run the `cvsinit' shell script. It will set up an empty repository in the directory defined by the environment variable `$CVSROOT'. (`cvsinit' is careful to never overwrite any existing files in the repository, so no harm is done if you run `cvsinit' on an already set-up repository. In fact, running it on an already set-up repository is the best way to update the various scripts from the `contrib' directory.)  File: cvs.info, Node: Environment variables, Next: Troubleshooting, Prev: Administrative files, Up: Top All environment variables which affect CVS ****************************************** This is a complete list of all environment variables that affect CVS. `$CVSIGNORE' A whitespace-separated list of file name patterns that CVS should ignore. *Note cvsignore::. `$CVSWRAPPERS' A whitespace-separated list of file name patterns that CVS should treat as wrappers. *Note Wrappers::. `$CVSREAD' If this is set, `checkout' and `update' will try hard to make the files in your working directory read-only. When this is not set, the default behavior is to permit modification of your working files. `$CVSROOT' Should contain the full pathname to the root of the CVS source repository (where the RCS history files are kept). This information must be available to CVS for most commands to execute; if `$CVSROOT' is not set, or if you wish to override it for one invocation, you can supply it on the command line: `cvs -d cvsroot cvs_command...' You may not need to set `$CVSROOT' if your CVS binary has the right path compiled in. `$EDITOR' `$CVSEDITOR' Specifies the program to use for recording log messages during commit. If not set, the default is `/usr/ucb/vi'. `$CVSEDITOR' overrides `$EDITOR'. `$CVSEDITOR' does not exist in CVS 1.3, but the next release will probably include it. `$PATH' If `$RCSBIN' is not set, and no path is compiled into CVS, it will use `$PATH' to try to find all programs it uses. `$RCSBIN' Specifies the full pathname of the location of RCS programs, such as co(1) and ci(1). If not set, a compiled-in value is used, or your `$PATH' is searched. CVS is a front-end to RCS. The following environment variables affect RCS: `$LOGNAME' `$USER' If set, they affect who RCS thinks you are. If you have trouble checking in files it might be because your login name differs from the setting of e.g. `$LOGNAME'. `$RCSINIT' Options prepended to the argument list, separated by spaces. A backslash escapes spaces within an option. The `$RCSINIT' options are prepended to the argument lists of most RCS commands. `$TMPDIR' `$TMP' `$TEMP' Name of the temporary directory. The environment variables are inspected in the order they appear above and the first value found is taken; if none of them are set, a host-dependent default is used, typically `/tmp'.  File: cvs.info, Node: Troubleshooting, Next: Copying, Prev: Environment variables, Up: Top Troubleshooting *************** * Menu: * Magic branch numbers:: Magic branch numbers  File: cvs.info, Node: Magic branch numbers, Up: Troubleshooting Magic branch numbers ==================== Externally, branch numbers consist of an odd number of dot-separated decimal integers. *Note Revision numbers::. That is not the whole truth, however. For efficiency reasons CVS sometimes inserts an extra 0 in the second rightmost position (1.2.3 becomes 1.2.0.3, 8.9.10.11.12 becomes 8.9.10.11.0.12 and so on). CVS does a pretty good job at hiding these so called magic branches, but in at least four places the hiding is incomplete. * The magic branch can appear in the output from `cvs status' in vanilla CVS 1.3. This is fixed in CVS 1.3-s2. * The magic branch number appears in the output from `cvs log'. This is much harder to fix, since `cvs log' runs `rlog' (which is part of the RCS distribution), and modifying `rlog' to know about magic branches would probably break someone's habits (if they use branch 0 for their own purposes). * You cannot specify a symbolic branch name to `cvs log'. * You cannot specify a symbolic branch name to `cvs admin'. You can use the `admin' command to reassign a symbolic name to a branch the way RCS expects it to be. If `R4patches' is assigned to the branch 1.4.2 (magic branch number 1.4.0.2) in file `numbers.c' you can do this: $ cvs admin -NR4patches:1.4.2 numbers.c It only works if at least one revision is already committed on the branch. Be very careful so that you do not assign the tag to the wrong number. (There is no way to see how the tag was assigned yesterday).
