[HACKERS] Some git conversion issues
Working on the git conversion with keywords, and I've noticed a couple of strange things that don't come up the same way in git. All of these are in non-code files, but they do defeat the identical tarball mode. For example, a number of files have commits showing up in cvs with nothing at all changed. This triggered an update of the keywords only, with no contents changed. For example, look at: http://anoncvs.postgresql.org/cvsweb.cgi/pgsql/doc/Attic/FAQ_AIX.diff?r1=1.19.2.9;r2=1.19.2.10 http://anoncvs.postgresql.org/cvsweb.cgi/pgsql/doc/Attic/FAQ_HPUX.diff?r1=1.14.2.9;r2=1.14.2.10 http://anoncvs.postgresql.org/cvsweb.cgi/pgsql/doc/Attic/FAQ_Solaris.diff?r1=1.22.2.10;r2=1.22.2.11 Some show up as completely empty, like: http://anoncvs.postgresql.org/cvsweb.cgi/pgsql/doc/src/sgml/generate_history.pl.diff?r1=1.1;r2=1.1.2.1 Does anybody know how this can even happen? Wouldn't cvs normally just not commit the file if there are no changes? I'm also seeing some entries tagged with vendor branch, such as: http://anoncvs.postgresql.org/cvsweb.cgi/pgsql/src/backend/storage/smgr/README revision 1.1.1.1 Same issue there, the file comes out on the other end with the wrong keyword (in this case, listed as 1.1). I admit I don't even know what a vendor branch is, except I know I've been annoyed by them before :-) Other than keywords, the contents of every branch and every tag are correct. I haven't checked any arbitrary revisions (that's really hard to do with cvs..), but I have a script that checks every branch and every tag present in configure, configure.in and README (in the root dir), which should hopefully cover everything. Does anybody know a better way to find out all tags and branches that exist, or some other file I should also be looking at? The full list of files having keyword issues due to these two things (AFAICT so far, these are the only issues) are: doc/FAQ_AIX doc/src/sgml/generate_history.pl doc/src/sgml/release-old.sgml src/backend/catalog/README src/backend/nodes/README src/backend/po/es.po src/backend/storage/ipc/README src/backend/storage/smgr/README src/bin/initdb/po/de.po src/bin/initdb/po/fr.po src/bin/pg_config/po/de.po src/bin/pg_config/po/fr.po src/bin/pg_controldata/po/de.po src/bin/pg_controldata/po/es.po src/bin/pg_controldata/po/fr.po src/bin/pg_ctl/po/de.po src/bin/pg_dump/po/de.po src/bin/pg_dump/po/fr.po src/bin/pg_dump/po/sv.po src/bin/pg_resetxlog/po/de.po src/bin/psql/po/de.po src/bin/psql/po/es.po src/bin/psql/po/fr.po src/bin/psql/po/sv.po src/bin/scripts/po/de.po src/bin/scripts/po/fr.po src/interfaces/libpq/po/de.po src/interfaces/libpq/po/fr.po src/interfaces/libpq/po/sv.po Any thoughts or ideas on how to fix these? Or shuld we accept and ignore those differences? -- Magnus Hagander Me: http://www.hagander.net/ Work: http://www.redpill-linpro.com/ -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers

Yeah, something like that. But why do we for the file above have one initial revision and one vendor branch, whereas for other files we don't? (and there's no difference betweenthem) Or rather, we do have two for example for md.c - but the second one is not listed as being on vendor branch. -- Magnus Hagander Me: http://www.hagander.net/ Work: http://www.redpill-linpro.com/ -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers

I quick check of CVS documentation indicates that 1.1.1 is reserved for the vendor branch created by an import. New vendor versions can be imported and will bump 1.1.1.1 to 1.1.1.2 and so on. When you commit a modification to a vendor branch file, it goes onto the trunk. So, either there was something which *looked* like a modification to CVS which got massaged out (whitespace or some such), or someone independently imported the file and someone (possibly a different someone) committed the file independently of the import. I think the latter is probably more likely, but the former seems within the realm of possibility. Where they are identical, unless the imported version is included in any tag or PostgreSQL branch, I would eliminate it and keep the normal copy. Short of maintaining a coherent history, I don't see the point of keeping two separate but identical revisions of a file. -Kevin -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers

Personally this never happens because I move files by making cvs diff in one and applying in the other, not copying the files. For one thing, this showed up in a lot of .po files for 8.1.0RC1. Peter, can you comment on if this coincides with the tools you use to do those things? so it is possible, and can be ignored. Yeah, but do we want to? It means a git checkout of the branch tip will be slightly different - in keywords only - from the previous checkout in cvs. -- Magnus Hagander Me: http://www.hagander.net/ Work: http://www.redpill-linpro.com/ -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers

Right now, it looks like cvs2git is best when we want the keywords included.
