System: 5.8-current/amd64 RCS gets confused if the latest revision is an empty file: checking out any other revision will only produce empty files.
Here's an example: $ rm -f foo foo,v $ echo hello world > foo $ ci -i -t-bla -l foo foo,v <-- foo initial revision: 1.1 done $ echo bonjour le monde > foo $ ci -msecond -l foo foo,v <-- foo revision 1.2 (locked) done $ : > foo $ ci -mthird -l foo # empty file foo,v <-- foo revision 1.3 (locked) done $ co -p1.1 foo # older revisions check out as empty! foo,v --> standard output revision 1.1 done $ co -p1.2 foo foo,v --> standard output revision 1.2 done Now we commit a non-empty revision on top: $ echo hallo welt > foo $ ci -mfourth -l foo foo,v <-- foo revision 1.4 (locked) done $ co -p1.1 foo # older revisions check out correctly! foo,v --> standard output revision 1.1 hello world done $ co -p1.2 foo foo,v --> standard output revision 1.2 bonjour le monde done $ co -p1.3 foo foo,v --> standard output revision 1.3 done $ co -p1.4 foo foo,v --> standard output revision 1.4 hallo welt done This bug also affects rcsdiff(1), which in turn causes CVSweb to display empty diffs, which is how I noticed. -- Christian "naddy" Weisgerber na...@mips.inka.de
