package VCP::Source::cvs ; =head1 NAME VCP::Source::cvs - A CVS repository source =head1 SYNOPSIS vcp cvs:module/... -d ">=2000-11-18 5:26:30" <dest> # All file revs newer than a date/time vcp cvs:module/... -r foo # all files in module and below labelled foo vcp cvs:module/... -r foo: # All revs of files labelled foo and newer, # including files not tagged with foo. vcp cvs:module/... -r 1.1:1.10 # revs 1.1..1.10 vcp cvs:module/... -r 1.1: # revs 1.1 and up on main trunk ## NOTE: Unlike cvs, vcp requires spaces after option letters. =head1 DESCRIPTION Source driver enabling L<C<vcp>|vcp> to extract versions form a cvs repository. The source specification for CVS looks like: cvs:cvsroot:module/filespec [<options>] or optionally, if the C<CVSROOT> environment variable is set: cvs:module/filespec [<options>] The cvsroot is passed to C<cvs> with cvs' C<-d> option. The filespec and E<lt>optionsE<gt> determine what revisions to extract. C<filespec> may contain trailing wildcards, like C</a/b/...> to extract an entire directory tree. If the cvsroot looks like a local filesystem (if it doesn't start with ":" and if it points to an existing directory or file), this module will read the RCS files directly from the hard drive unless --use-cvs is passed. This is more accurate (due to poor design of the cvs log command) and much, much faster. =head1 OPTIONS =over =item --cd Used to set the CVS working directory. VCP::Source::cvs will cd to this directory before calling cvs, and won't initialize a CVS workspace of it's own (normally, VCP::Source::cvs does a "cvs checkout" in a temporary directory). This is an advanced option that allows you to use a CVS workspace you establish instead of letting vcp create one in a temporary directory somewhere. This is useful if you want to read from a CVS branch or if you want to delete some files or subdirectories in the workspace. If this option is a relative directory, then it is treated as relative to the current directory. =item -k -k sadf Pass the CVS -k options through to the underlying CVS command. =item -kb Pass the -kb option to cvs, forces a binary checkout. This is useful when you want a text file to be checked out with Unix linends, or if you know that some files in the repository are not flagged as binary files and should be. =item -r -r v_0_001:v_0_002 -r v_0_002: Passed to C<cvs log> as a C<-r> revision specification. This corresponds to the C<-r> option for the rlog command, not either of the C<-r> options for the cvs command. Yes, it's confusing, but "cvs log" calls "rlog" and passes the options through. =item --use-cvs Do not try to read local repositories directly; use the cvs command line interface. This is much slower than reading the files directly but is useful to see if there is a bug in the RCS file parser or possibly when dealing with corrupt RCS files that cvs will read. If you find that this option makes something work, then there is a discrepancy between the code that reads the RCS files directly (in the absence of this option) and cvs itself. Please let me know (barrie@slaysys.com). Thanks. =item -d -d "2000-11-18 5:26:30<=" Passed to 'cvs log' as a C<-d> date specification. WARNING: if this string doesn't contain a '>' or '<', you're probably doing something wrong, since you're not specifying a range. vcp may warn about this in the future. see "log" command in cvs(1) man page for syntax of the date specification. =back =head1 CVS Conversion issues =head2 Files that aren't tagged CVS has one peculiarity that this driver works around. If a file does not contain the tag(s) used to select the source files, C<cvs log> outputs the entire life history of that file. We don't want to capture the entire history of such files, so L<VCP::Source::cvs> ignores any revisions before and after the oldest and newest tagged file. =head2 Branches with multiple tags / "cloned" branches CVS allows branches to be tagged with multiple tags using a command like cvs admin second_branch_tag:branch_tag When VCP::Source::cvs notices this, it creates multiple branches with identical revisions. This is done by choosing the first branch tag for the branches to be the primary branch and applying all actual changes to it then "clone"ing each revision from that branch to all others. For instance, if file foo is branched once in to a branch tagged with "bar" and later a "goof" tag is aliased to the "bar" tag, then trunk branch bar branch goof ======= ================ ================== foo#1.1 | \ | \ | \ ... foo#1.1.1.1<bar> | \ | \ | \ | foo#1.1.1.1<goof> | foo#1.1.1.2<bar> | \ | \ | \ | foo#1.1.1.2<goof> | ... This is EXPERIMENTAL and it's likely to give VCP::Dest::cvs fits. It is tested with CVS->p4 transfers. If you only want the primary branch, you may use a Map: section in the .vcp file to discard non-primary branches: Map: ...<goof> <<delete>> Currently, there is no way to ignore the primary branch other than getting rid of that branch tag in the RCS files or hacking VCP::Source::cvs's source code to ignore it. =head1 FEATURES (EXPERIMENTAL) It's possible somehow (I've never done it) to set the state on edited revisions to "dead", which may result in a series of revisions all marked "dead". CVS, at least older versions, deleted a file by marking the head rev as state "dead" instead of adding a new revision. So a dead revision is both an edit and a deletion. I am not sure whether the metadata on the rev refers to the time and user that committed the edit, or the time and user that committed the delete. VCP::Source::cvs detects consecutive "dead" revisions and "dead" revisions that are also edits and issues a normal "edit" revision followed by a concocted "delete" revision with a ".0" appended to the rev_id. =head1 LIMITATIONS Stores all revisions for a file in RAM before sending so it can link all the revisions properly. Also stores all branch parents and the first revision on every branch for all files scanned so it can insert placeholders for branches with no revs. Except for these branch point revisions, all other revs for each file are sent before the next file is scanned. TODO: just send placeholders for all branches that match the filespec and revspec? Does not yet set the same time in all branch creation revisions. This may be necessary in order to help the changeset aggregator. It will probably take buffering all branch revs before sending them on. Also, it is not possible in the general case: not all files on a branch are actually branched from parents that are checked in before the first file on a branch is created. It also makes no sense to do this for untagged branches as there is no detectable semantic association between untagged branches. CVS does not try to protect itself from people checking in things that look like snippets of CVS log file: they come out exactly like they went in, confusing the log file parser. So, if a repository contains messages in the log file that look like the output from some other "cvs log" command, things will likely go awry when using remote repositories (local repositories are read directly and do not suffer this problem). The direct RCS file parser does not have this problem. CVS stores the -k keyword expansion setting per file, not per revision, so vcp will mark all revisions of a file with the current setting of the -k flag for a file. At least one cvs repository out there has multiple revisions of a single file with the same rev number. The second and later revisions with the same rev number are ignored with a warning like "Can't add same revision twice:...". The xfree86 repository has several files xc/programs/Xserver/hw/xfree86//vga256/drivers/s3/s3Bt485.h: 1.2 dead lines +1, -1 1.1 Exp lines 1.2.2.2 Exp lines +1, -1 1.2.2.1 Exp lines +1, -1 In this case, VCP::Source::cvs doesn't know how to retrieve rev 1.2 to create the branch 1.2.2.x, so it uses 1.1. If you know how to force it to get rev 1.2, please let me know (in the future, the RCS parser will allow this, but currently we always use cvs checkout to retrieve versions). I'd like to know how to use the cvs command to modify a revision and then force it to the dead state without upping the revision number, as that appears to have happened here. I suspect something other than the cvs command at play here, like the rcs command or RCS file editing by hand or by script =for test_script t/80rcs_parser.t t/91cvs2revml.t =cut $VERSION = 1.2 ; # Removed docs for -f, since I now think it's overcomplicating things... #Without a -f This will normally only replicate files which are tagged. This #means that files that have been added since, or which are missing the tag for #some reason, are ignored. # #Use the L</-f> option to force files that don't contain the tag to be #=item -f # #This option causes vcp to attempt to export files that don't contain a #particular tag but which occur in the date range spanned by the revisions #specified with -r. The typical use is to get all files from a certain #tag to now. # #It does this by exporting all revisions of files between the oldest and #newest files that the -r specified. Without C<-f>, these would #be ignored. # #It is an error to specify C<-f> without C<-r>. # #exported. =begin developerdocs CVS branching needs some help to allow VCP::Dest::* drivers to branch files appropriately because CVS branch creation (cvs rtag -b) does not actually create a branched revision, it marks the parent revision for a branch. However, we need to include information about all the files that should be branched when a branch is created. CVS does not reliably record the data of branch creation (though we might be able to find it in CVS history, I have not found that to be a reliable approach; different CVS versions seem to capture different things, at least by default). There's a dilemma here: we need to create branched revisions for created branches, but we don't know when to do it. So the first time we see a change on a branch, we create dummy revisions for all files that are also on that branch. These dummy revisions are VCP::Rev instances with a ".0" rev_id and with no <digest>, <delta>, <content>, or <delete> elements. See the docs for VCP::Rev::is_placeholder_rev(). Detection of branches that have been initiated this transfer has to occur after unwanted revisions are thrown out (due to rev_id < last_rev_in_filebranch or due to culling of unwanted revs) so we don't think all branches have been created this transfer. =end developerdocs =cut use strict ; use Carp ; use VCP::Debug qw( :debug :profile ) ; use VCP::Logger qw( lg pr pr_doing pr_done pr_done_failed BUG ); use VCP::Rev qw( iso8601format ); use VCP::Source ; use VCP::Utils qw( empty is_win32 shell_quote start_dir_rel2abs xchdir ); use VCP::Utils::cvs ; use constant debug_parser => 0; use base qw( VCP::Source VCP::Utils::cvs ) ; use fields ( 'CVS_INFO', ## Results of the 'cvs --version' command and CVSROOT 'CVS_REV_SPEC', ## The revision spec to pass to `cvs log` 'CVS_DATE_SPEC', ## The date spec to pass to `cvs log` 'CVS_WORK_DIR', ## working directory set via --cd option 'CVS_USE_CVS', ## holds the value of the --use-cvs option 'CVS_K_OPTION', ## Which of the CVS/RCS "-k" options to use, if any 'CVS_PARSE_RCS_FILES', ## Read CVS files directly instead of through the ## cvs command.

#58 | 3013 | Barrie Slaymaker | Clean up minor undefined var warning discovered in testing | ||
#57 | 3010 | Barrie Slaymaker |

#55 | 2982 | Barrie Slaymaker | Treat 1.0, 2.0, 3.0 as first revs | ||

removed CVS_CONTINUE field from Source/cvs.pm, and added CONTINUE field and continue accessor to Source.pm. Moved parsing of the --continue option also. |
||
#47 | 2809 | Barrie Slaymaker |
Implement --repo-id in Plugin.pm, refactor source & dest options parsing starting in VCP::Source::cvs (need to roll out to other sources and dests), get t/91cvs2revml.t passing again (first time in months! branching and --continue support works in cvs->foo!). |
||
#46 | 2802 | John Fetkovich |
Added a source_repo_id to each revision, and repo_id to each Source and Dest. The repo_ids include repository type (cvs,p4,revml,vss,...) and the repo_server fields. Changed the $self->...->set() and $self->...->get() lines in VCP::Dest::* to pass in a conglomerated key value, by passing in the key as an ARRAY ref. Also various restructuring in VCP::DB.pm, VCP::DB_file.pm and VCP::DB_file::sdbm.pm related to this change. |
||
#45 | 2800 | Barrie Slaymaker | Get --continue working in cvs->foo transfers. | ||

Extend VCP::Rev to have the fields 4. Extend VCP::{Source,Dest}::revml to read/write the fields (VCP::Dest::revml should die() if VCP tries to emit illegal RevML) 5. Extend VCP::{Source,Dest}::{cvs,p4} to read the fields 7. Get all tests through t/91*.t to pass except those that rely on ch_4 labels |
||
#43 | 2667 | Barrie Slaymaker | Convert more to IPC::Run3 | ||
#42 | 2389 | John Fetkovich |

#10 | 630 | Barrie Slaymaker |
Fix bug in CVS log file parsing that made it think it was always seeing the same file, different revisions over and over again. Reported by Matthew Attaway. |
||
#9 | 628 | Barrie Slaymaker | Cleaned up POD in bin/vcp, added BSD-style license. | ||
#8 | 627 | Barrie Slaymaker | Beef up CVS log file parsing. | ||
#7 | 626 | Barrie Slaymaker | Removed POD that was older than the current feature set. | ||
#6 | 625 | Barrie Slaymaker | Add NOTE about required " " in cvs options. | ||
#5 | 624 | Barrie Slaymaker | Add a space to bin/vcp SYNOPSIS after the cvs -r option. | ||
#4 | 480 | Barrie Slaymaker |
0.06 Wed Dec 20 23:19:15 EST 2000 - bin/vcp: Added --versions, which loads all modules and checks them for a $VERSION and print the results out. This should help with diagnosing out-of-sync modules. - Added $VERSION vars to a few modules :-). Forgot to increment any $VERSION strings. - VCP::Dest::cvs: The directory "deeply" was not being `cvs add`ed on paths like "a/deeply/nested/file", assuming "deeply" had no files in it. - VCP::Dest::revml: fixed a bug that was causing files with a lot of linefeeds to be emitted in base64 instead of deltaed. This means most text files. - Various minor cleanups of diagnostics and error messages, including exposing "Can't locate Foo.pm" when a VCP::Source or VCP::Dest module depends on a module that's not installed, as reported by Jeff Anton. |
||
#3 | 478 | Barrie Slaymaker |
0.05 Mon Dec 18 07:27:53 EST 2000 - Use `p4 labels //...@label` command as per Rober Cowham's suggestion, with the '-s' flag recommended by Christopher Siewald and Amaury.FORGEOTDARC@atsm.fr. Though it's actually something like vcp: running /usr/bin/p4 -u safari -c safari -p localhost:5666 -s files //.../NtLkly //...@compiler_a3 //.../NtLkly //...@compiler_may3 and so //on //for 50 parameters to get the speed up. I use the //.../NtLkly "file" as //a separator between the lists of files in various //revisions. Hope nobody has any files named that :-). What I should do is choose a random label that doesn't occur in the labels list, I guess. - VCP::Source::revml and VCP::Dest::revml are now binary, control code, and "hibit ASCII" (I know, that's an oxymoron) clean. The <comment>, <delta>, and <content> elements now escape anything other than tab, line feed, space, or printable chars (32 <= c <= ASCII 126) using a tag like '<char code="0x09">'. The test suite tests all this. Filenames should also be escaped this way, but I didn't get to that. - The decision whether to do deltas or encode the content in base64 is now based on how many characters would need to be escaped. - We now depend on the users' diff program to have a "-a" option to force it to diff even if the files look binary to it. I need to use Diff.pm and adapt it for use on binary data. - VCP::Dest::cvs now makes sure that no two consecutive revisions of the same file have the same mod_time. VCP::Source::p4 got so fast at pulling revisions from the repositories the test suite sets up that CVS was not noticing that files had changed. - VCP::Plugin now allows you to set a list of acceptable result codes, since we now use p4 in ways that make it return non-zero result codes. - VCP::Revs now croaks if you try to add two entries of the same VCP::Rev (ie matching filename and rev_id). - The <type> tag is now limited to "text" or "binary", and is meant to pass that level of info between foreign repositories. - The <p4_info> on each file now carries the one line p4 description of the file so that p4->p4 transferes can pick out the more detailed info. VCP::Source::p4, VCP::Dest::p4 do this. - VCP::{Source,Dest}::{p4,cvs} now set binaryness on added files properly, I think. For p4->p4, the native p4 type is preserved. For CVS sources, seeing the keyword substitution flag 'o' or 'b' implies binaryness, for p4, seeing a filetype like qr/u?x?binary/ or qr/x?tempobj/ or "resource" implies binaryness (to non-p4 destinations). NOTE: Seeing a 'o' or 'b' in a CVS source only ends up setting the 'b' option on the destination. That should be ok for most uses, but we can make it smarter for cvs->cvs transfers if need be. |
||
#2 | 468 | Barrie Slaymaker |
- VCP::Dest::p4 now does change number aggregation based on the comment field changing or whenever a new revision of a file with unsubmitted changes shows up on the input stream. Since revisions of files are normally sorted in time order, this should work in a number of cases. I'm sure we'll need to generalize it, perhaps with a time thresholding function. - t/90cvs.t now tests cvs->p4 replication. - VCP::Dest::p4 now doesn't try to `p4 submit` when no changes are pending. - VCP::Rev now prevents the same label from being applied twice to a revision. This was occuring because the "r_1"-style label that gets added to a target revision by VCP::Dest::p4 could duplicate a label "r_1" that happened to already be on a revision. - Added t/00rev.t, the beginnings of a test suite for VCP::Rev. - Tweaked bin/gentrevml to comment revisions with their change number instead of using a unique comment for every revision for non-p4 t/test-*-in-0.revml files. This was necessary to test cvs->p4 functionality. |
