A script that implements uppercasing all letters in a file. $ UPPERCASEPY="$TESTTMP/uppercase.py" $ cat > $UPPERCASEPY <<EOF > import sys > from mercurial.utils.procutil import setbinary > setbinary(sys.stdin) > setbinary(sys.stdout) > sys.stdout.write(sys.stdin.read().upper()) > EOF $ TESTLINES="foo\nbar\nbaz\n" $ printf $TESTLINES | "$PYTHON" $UPPERCASEPY FOO BAR BAZ Tests for the fix extension's behavior around non-trivial history topologies. Looks for correct incremental fixing and reproduction of parent/child relationships. We indicate fixed file content by uppercasing it. $ cat >> $HGRCPATH <<EOF > [extensions] > fix = > strip = > [fix] > uppercase-whole-file:command="$PYTHON" $UPPERCASEPY > uppercase-whole-file:pattern=set:** > EOF This tests the only behavior that should really be affected by obsolescence, so we'll test it with evolution off and on. This only changes the revision numbers, if all is well. #testcases obsstore-off obsstore-on #if obsstore-on $ cat >> $HGRCPATH <<EOF > [experimental] > evolution.createmarkers=True > evolution.allowunstable=True > EOF #endif Setting up the test topology. Scroll down to see the graph produced. We make it clear which files were modified in each revision. It's enough to test at the file granularity, because that demonstrates which baserevs were diffed against. The computation of changed lines is orthogonal and tested separately. $ hg init repo $ cd repo $ printf "aaaa\n" > a $ hg commit -Am "change A" adding a $ printf "bbbb\n" > b $ hg commit -Am "change B" adding b $ printf "cccc\n" > c $ hg commit -Am "change C" adding c $ hg checkout 0 0 files updated, 0 files merged, 2 files removed, 0 files unresolved $ printf "dddd\n" > d $ hg commit -Am "change D" adding d created new head $ hg merge -r 2 2 files updated, 0 files merged, 0 files removed, 0 files unresolved (branch merge, don't forget to commit) $ printf "eeee\n" > e $ hg commit -Am "change E" adding e $ hg checkout 0 0 files updated, 0 files merged, 4 files removed, 0 files unresolved $ printf "ffff\n" > f $ hg commit -Am "change F" adding f created new head $ hg checkout 0 0 files updated, 0 files merged, 1 files removed, 0 files unresolved $ printf "gggg\n" > g $ hg commit -Am "change G" adding g created new head $ hg merge -r 5 1 files updated, 0 files merged, 0 files removed, 0 files unresolved (branch merge, don't forget to commit) $ printf "hhhh\n" > h $ hg commit -Am "change H" adding h $ hg merge -r 4 4 files updated, 0 files merged, 0 files removed, 0 files unresolved (branch merge, don't forget to commit) $ printf "iiii\n" > i $ hg commit -Am "change I" adding i $ hg checkout 2 0 files updated, 0 files merged, 6 files removed, 0 files unresolved $ printf "jjjj\n" > j $ hg commit -Am "change J" adding j created new head $ hg checkout 7 3 files updated, 0 files merged, 3 files removed, 0 files unresolved $ printf "kkkk\n" > k $ hg add adding k $ hg log --graph --template '{rev} {desc}\n' o 9 change J | | o 8 change I | |\ | | @ 7 change H | | |\ | | | o 6 change G | | | | | | o | 5 change F | | |/ | o | 4 change E |/| | | o | 3 change D | |/ o | 2 change C | | o | 1 change B |/ o 0 change A Fix all but the root revision and its four children. $ hg fix -r '2|4|7|8|9' --working-dir saved backup bundle to * (glob) (obsstore-off !) The five revisions remain, but the other revisions were fixed and replaced. All parent pointers have been accurately set to reproduce the previous topology (though it is rendered in a slightly different order now). #if obsstore-on $ hg log --graph --template '{rev} {desc}\n' o 14 change J | | o 13 change I | |\ | | @ 12 change H | | |\ | o | | 11 change E |/| | | o | | | 10 change C | | | | | | | o 6 change G | | | | | | o | 5 change F | | |/ | o / 3 change D | |/ o / 1 change B |/ o 0 change A $ C=10 $ E=11 $ H=12 $ I=13 $ J=14 #else $ hg log --graph --template '{rev} {desc}\n' o 9 change J | | o 8 change I | |\ | | @ 7 change H | | |\ | o | | 6 change E |/| | | o | | | 5 change C | | | | | | | o 4 change G | | | | | | o | 3 change F | | |/ | o / 2 change D | |/ o / 1 change B |/ o 0 change A $ C=5 $ E=6 $ H=7 $ I=8 $ J=9 #endif Change C is a root of the set being fixed, so all we fix is what has changed since its parent. That parent, change B, is its baserev. $ hg cat -r $C 'set:**' aaaa bbbb CCCC Change E is a merge with only one parent being fixed. Its baserevs are the unfixed parent plus the baserevs of the other parent. This evaluates to changes B and D. We now have to decide what it means to incrementally fix a merge commit. We choose to fix anything that has changed versus any baserev. Only the undisturbed content of the common ancestor, change A, is unfixed. $ hg cat -r $E 'set:**' aaaa BBBB CCCC DDDD EEEE Change H is a merge with neither parent being fixed. This is essentially equivalent to the previous case because there is still only one baserev for each parent of the merge. $ hg cat -r $H 'set:**' aaaa FFFF GGGG HHHH Change I is a merge that has four baserevs; two from each parent. We handle multiple baserevs in the same way regardless of how many came from each parent. So, fixing change H will fix any files that were not exactly the same in each baserev. $ hg cat -r $I 'set:**' aaaa BBBB CCCC DDDD EEEE FFFF GGGG HHHH IIII Change J is a simple case with one baserev, but its baserev is not its parent, change C. Its baserev is its grandparent, change B. $ hg cat -r $J 'set:**' aaaa bbbb CCCC JJJJ The working copy was dirty, so it is treated much like a revision. The baserevs for the working copy are inherited from its parent, change H, because it is also being fixed. $ cat * aaaa FFFF GGGG HHHH KKKK Change A was never a baserev because none of its children were to be fixed. $ cd .. Test the --source option. We only do this with obsstore on to avoid duplicating test code. We rely on the other tests to prove that obsolescence is not an important factor here. #if obsstore-on $ hg init source-arg $ cd source-arg $ printf "aaaa\n" > a $ hg commit -Am "change A" adding a $ printf "bbbb\n" > b $ hg commit -Am "change B" adding b $ printf "cccc\n" > c $ hg commit -Am "change C" adding c $ hg checkout 0 0 files updated, 0 files merged, 2 files removed, 0 files unresolved $ printf "dddd\n" > d $ hg commit -Am "change D" adding d created new head $ hg log --graph --template '{rev} {desc}\n' @ 3 change D | | o 2 change C | | | o 1 change B |/ o 0 change A Test passing 'wdir()' to --source $ printf "xxxx\n" > x $ hg add x $ hg fix -s 'wdir()' $ cat * aaaa dddd XXXX Test passing '.' to --source $ printf "xxxx\n" > x $ hg fix -s . $ hg log --graph --template '{rev} {desc}\n' @ 4 change D | | o 2 change C | | | o 1 change B |/ o 0 change A $ cat * aaaa DDDD XXXX $ hg strip -qf 4 $ hg co -q 3 Test passing other branch to --source $ printf "xxxx\n" > x $ hg add x $ hg fix -s 2 $ hg log --graph --template '{rev} {desc}\n' o 4 change C | | @ 3 change D | | o | 1 change B |/ o 0 change A $ hg cat -r 4 b c bbbb CCCC $ cat * aaaa dddd xxxx $ hg strip -qf 4 Test passing multiple revisions to --source $ hg fix -s '2 + .' $ hg log --graph --template '{rev} {desc}\n' @ 5 change D | | o 4 change C | | | o 1 change B |/ o 0 change A $ hg cat -r 4 b c bbbb CCCC $ cat * aaaa DDDD XXXX $ cd .. #endif The --all flag should fix anything that wouldn't cause a problem if you fixed it, including the working copy. Obsolete revisions are not fixed because that could cause divergence. Public revisions would cause an abort because they are immutable. We can fix orphans because their successors are still just orphans of the original obsolete parent. When obsolesence is off, we're just fixing and replacing anything that isn't public. $ hg init fixall $ cd fixall $ hg fix --all --working-dir abort: cannot specify both --working-dir and --all [255] #if obsstore-on $ printf "one\n" > foo.whole $ hg commit -Aqm "first" $ hg phase --public $ hg tag --local root $ printf "two\n" > foo.whole $ hg commit -m "second" $ printf "three\n" > foo.whole $ hg commit -m "third" --secret $ hg tag --local secret $ hg checkout root 1 files updated, 0 files merged, 0 files removed, 0 files unresolved $ printf "four\n" > foo.whole $ hg commit -m "fourth" created new head $ printf "five\n" > foo.whole $ hg commit -m "fifth" $ hg tag --local replaced $ printf "six\n" > foo.whole $ hg commit -m "sixth" $ hg checkout replaced 1 files updated, 0 files merged, 0 files removed, 0 files unresolved $ printf "seven\n" > foo.whole $ hg commit --amend 1 new orphan changesets $ hg checkout secret 1 files updated, 0 files merged, 0 files removed, 0 files unresolved $ printf "uncommitted\n" > foo.whole $ hg log --graph --template '{rev} {desc} {phase}\n' o 6 fifth draft | | * 5 sixth draft | | | x 4 fifth draft |/ o 3 fourth draft | | @ 2 third secret | | | o 1 second draft |/ o 0 first public $ hg fix --all $ hg log --graph --template '{rev} {desc}\n' -r 'sort(all(), topo)' --hidden o 11 fifth | o 9 fourth | | @ 8 third | | | o 7 second |/ | * 10 sixth | | | | x 5 sixth | |/ | x 4 fifth | | | | x 6 fifth | |/ | x 3 fourth |/ | x 2 third | | | x 1 second |/ o 0 first $ hg cat -r 7 foo.whole TWO $ hg cat -r 8 foo.whole THREE $ hg cat -r 9 foo.whole FOUR $ hg cat -r 10 foo.whole SIX $ hg cat -r 11 foo.whole SEVEN $ cat foo.whole UNCOMMITTED #else $ printf "one\n" > foo.whole $ hg commit -Aqm "first" $ hg phase --public $ hg tag --local root $ printf "two\n" > foo.whole $ hg commit -m "second" $ printf "three\n" > foo.whole $ hg commit -m "third" --secret $ hg tag --local secret $ hg checkout root 1 files updated, 0 files merged, 0 files removed, 0 files unresolved $ printf "four\n" > foo.whole $ hg commit -m "fourth" created new head $ printf "uncommitted\n" > foo.whole $ hg log --graph --template '{rev} {desc} {phase}\n' @ 3 fourth draft | | o 2 third secret | | | o 1 second draft |/ o 0 first public $ hg fix --all saved backup bundle to * (glob) $ hg log --graph --template '{rev} {desc} {phase}\n' @ 3 fourth draft | | o 2 third secret | | | o 1 second draft |/ o 0 first public $ hg cat -r 0 foo.whole one $ hg cat -r 1 foo.whole TWO $ hg cat -r 2 foo.whole THREE $ hg cat -r 3 foo.whole FOUR $ cat foo.whole UNCOMMITTED #endif $ cd ..
