context: introduce p[12]copies() methods and debugp[12]copies commands
As mentioned earlier, I'm working on support for storing copy metadata
in the changeset instead of in the filelog.
In order to transition a repo from storing metadata in filelogs to
storing it in the changeset, I'm going to provide a config option for
reading the metadata from the changeset, but falling back to getting
it from the filelog if it's not in the changeset. In this compatiblity
mode, the changeset-optmized algorithms will be used. We will then
need to convert the filelog copy metadata to look like that provided
by changeset copy metadata. This patch introduces methods that do just
that.
By having these methods here, we can start writing changeset-optimized
algorithms that should work already before we add any support for
storing the metadata in the changesets.
This commit also includes new debugp[12]copies commands and exercises
them in test-copies.t.

The simple store doesn't escape paths robustly and can't store paths with periods, etc. So much of this test fails with it. #require no-reposimplestore $ hg init audit of .hg $ hg add .hg/00changelog.i abort: path contains illegal component: .hg/00changelog.i [255] #if symlink Symlinks $ mkdir a $ echo a > a/a $ hg ci -Ama adding a/a $ ln -s a b $ echo b > a/b $ hg add b/b abort: path 'b/b' traverses symbolic link 'b' [255] $ hg add b should still fail - maybe $ hg add b/b abort: path 'b/b' traverses symbolic link 'b' [255] $ hg commit -m 'add symlink b' Test symlink traversing when accessing history: ----------------------------------------------- (build a changeset where the path exists as a directory) $ hg up 0 0 files updated, 0 files merged, 1 files removed, 0 files unresolved $ mkdir b $ echo c > b/a $ hg add b/a $ hg ci -m 'add directory b' created new head Test that hg cat does not do anything wrong the working copy has 'b' as directory $ hg cat b/a c $ hg cat -r "desc(directory)" b/a c $ hg cat -r "desc(symlink)" b/a b/a: no such file in rev bc151a1f53bd [1] Test that hg cat does not do anything wrong the working copy has 'b' as a symlink (issue4749) $ hg up 'desc(symlink)' 1 files updated, 0 files merged, 1 files removed, 0 files unresolved $ hg cat b/a b/a: no such file in rev bc151a1f53bd [1] $ hg cat -r "desc(directory)" b/a c $ hg cat -r "desc(symlink)" b/a b/a: no such file in rev bc151a1f53bd [1] #endif unbundle tampered bundle $ hg init target $ cd target $ hg unbundle "$TESTDIR/bundles/tampered.hg" adding changesets adding manifests adding file changes added 5 changesets with 6 changes to 6 files (+4 heads) new changesets b7da9bf6b037:fc1393d727bc (5 drafts) (run 'hg heads' to see heads, 'hg merge' to merge) attack .hg/test $ hg manifest -r0 .hg/test $ hg update -Cr0 abort: path contains illegal component: .hg/test [255] attack foo/.hg/test $ hg manifest -r1 foo/.hg/test $ hg update -Cr1 abort: path 'foo/.hg/test' is inside nested repo 'foo' [255] attack back/test where back symlinks to .. $ hg manifest -r2 back back/test #if symlink $ hg update -Cr2 abort: path 'back/test' traverses symbolic link 'back' [255] #else ('back' will be a file and cause some other system specific error) $ hg update -Cr2 abort: $TESTTMP/target/back/test: $ENOTDIR$ [255] #endif attack ../test $ hg manifest -r3 ../test $ mkdir ../test $ echo data > ../test/file $ hg update -Cr3 abort: path contains illegal component: ../test [255] $ cat ../test/file data attack /tmp/test $ hg manifest -r4 /tmp/test $ hg update -Cr4 abort: path contains illegal component: /tmp/test [255] $ cd ..
