revlog: use compression engine API for compression
This commit swaps in the just-added revlog compressor API into
the revlog class.
Instead of implementing zlib compression inline in compress(), we
now store a cached-on-first-use revlog compressor on each revlog
instance and invoke its "compress()" method.
As part of this, revlog.compress() has been refactored a bit to use
a cleaner code flow and modern formatting (e.g. avoiding
parenthesis around returned tuples).
On a mozilla-unified repo, here are the "compress" times for a few
commands:
$ hg perfrevlogchunks -c
! wall 5.772450 comb 5.780000 user 5.780000 sys 0.000000 (best of 3)
! wall 5.795158 comb 5.790000 user 5.790000 sys 0.000000 (best of 3)
$ hg perfrevlogchunks -m
! wall 9.975789 comb 9.970000 user 9.970000 sys 0.000000 (best of 3)
! wall 10.019505 comb 10.010000 user 10.010000 sys 0.000000 (best of 3)
Compression times did seem to slow down just a little. There are
360,210 changelog revisions and 359,342 manifest revisions. For the
changelog, mean time to compress a revision increased from ~16.025us to
~16.088us. That's basically a function call or an attribute lookup. I
suppose this is the price you pay for abstraction. It's so low that
I'm not concerned.

Test update logic when there are renames or weird same-name cases between dirs and files Update with local changes across a file rename $ hg init r1 && cd r1 $ echo a > a $ hg add a $ hg ci -m a $ hg mv a b $ hg ci -m rename $ echo b > b $ hg ci -m change $ hg up -q 0 $ echo c > a $ hg up merging a and b to b warning: conflicts while merging b! (edit, then use 'hg resolve --mark') 0 files updated, 0 files merged, 0 files removed, 1 files unresolved use 'hg resolve' to retry unresolved file merges [1] Test update when local untracked directory exists with the same name as a tracked file in a commit we are updating to $ hg init r2 && cd r2 $ echo root > root && hg ci -Am root # rev 0 adding root $ echo text > name && hg ci -Am "name is a file" # rev 1 adding name $ hg up 0 0 files updated, 0 files merged, 1 files removed, 0 files unresolved $ mkdir name $ hg up 1 1 files updated, 0 files merged, 0 files removed, 0 files unresolved Test update when local untracked directory exists with some files in it and has the same name a tracked file in a commit we are updating to. In future this should be updated to give an friendlier error message, but now we should just make sure that this does not erase untracked data $ hg up 0 0 files updated, 0 files merged, 1 files removed, 0 files unresolved $ mkdir name $ echo text > name/file $ hg st ? name/file $ hg up 1 abort: *: '$TESTTMP/r1/r2/name' (glob) [255] $ cd .. #if symlink Test update when two commits have symlinks that point to different folders $ hg init r3 && cd r3 $ echo root > root && hg ci -Am root adding root $ mkdir folder1 && mkdir folder2 $ ln -s folder1 folder $ hg ci -Am "symlink to folder1" adding folder $ rm folder $ ln -s folder2 folder $ hg ci -Am "symlink to folder2" $ hg up 1 1 files updated, 0 files merged, 0 files removed, 0 files unresolved $ cd .. #endif #if rmcwd Test that warning is printed if cwd is deleted during update $ hg init r4 && cd r4 $ mkdir dir $ cd dir $ echo a > a $ echo b > b $ hg add a b $ hg ci -m "file and dir" $ hg up -q null current directory was removed (consider changing to repo root: $TESTTMP/r1/r4) #endif
