plan9: setup check for current python build

add: check for the existence of a file matched inexactly before adding it The change in 10697f29af2b created a problem on Windows and OS X: --- /usr/local/mercurial/tests/test-issue660.t +++ /usr/local/mercurial/tests/test-issue660.t.err @@ -47,6 +47,8 @@ Should succeed - shadow removed: $ hg add b + adding b/b + b/b does not exist! Prior to the failing 'hg add', the file 'b/b' was added and committed, then 'b' was recursively deleted from the filesystem, file 'b' was created and the delete was recorded with 'hg rm --after'. This add is attempting to record the existence of file 'b'. A filesystem that is not case sensitive prevents dirstate.walk() from skipping its step 3, and step 3 has the effect of inserting removed files into the walk list. The Linux code doesn't run through step 3, and didn't exhibit the problem. It's not clear why a non case sensitive filesystem triggers step 3, given that the path normalization occurs in step 2. Prior to 10697f29af2b, part of the check here was 'f not in repo.dirstate' instead of 'f not in wctx'. Files in the 'r' state are filtered out of context.__contains__() but not dirstate.__contains__(). Therefore the removed file name wasn't added to the list of files to add when checking against dirstate. That change was to allow removed files to be readded, but adding a file that doesn't exist is nonsensical. If the user specifies a missing file, it will be an exact match and will still fail.

tests: choose the proper environment variable style for the platform Windows was printing out 'commit $HG_NODE' instead of the actual hash.

tests: fix another multi-statement hook for Windows The double quotes are necessary, otherwise it tries to pipe into a program named 'short'. An '&' could serve as a command separator on Windows instead of ';', but I don't see any obvious way to swap these depending on the platform. In this case though, there really wasn't a need for multiple statements.

run-tests: set a default largefiles usercache in the default hgrc file This fixes a test failure introduced in 4be754832829 on Windows and OS X, where the cached largefile wasn't being deleted because the named .cache directory didn't exist. It only existed on Linux because the test suite sets $HOME to the directory of the test being run, and Linux uses $HOME/.cache by default. Most of the other largefiles tests explicitly set this value at the top of their scripts, but test-largefiles-update.t didn't pick that up when it was created. Those scripts that do set a value will override this. We could just set the parameter in the test-largefiles-update.t script, but there are a few other non obvious tests that exercise largefiles too. These largefiles end up being cached in the user's real cache, so proper hygiene dictates that this not be left to each individual test script.

merge: remove obsolete check for untracked files in 'dm' action Since 0776a6cababe (merge: don't use unknown(), 2012-02-09), untracked files are no longer included in the manifest diff, so there is no need to check exclude them when renaming files for directory moves with the 'dm' action.

merge: remove dead assignment in applyupdates()

merge: move calculateupdates() before applyupdated() calculateupdates() happens before applyupdates(), so move it before in the code. That also moves it close to manifestmerge(), which is a good location as calculateupdates() is the only caller of manifestmerge().

merge: remove unused variables from _checkcollision()

largefiles: avoid exec-bit examination on the platform being unaware of it Changeset 24600c9d7f4e introduced the examination of exec bit of largefiles in "hg status --rev REV" case, but it doesn't avoid it on the platform being unaware of exec-bit (e.g. on NTFS of Windows).

changegroup: fix file linkrevs during reorders (issue4462) Previously, if reorder was true during the creation of a changegroup bundle, it was possible that the manifest and filelogs would be reordered such that the resulting bundle filelog had a linkrev that pointed to a commit that was not the earliest instance of the filelog revision. For example: With commits: 0<-1<---3<-4 \ / --2<--- if 2 and 3 added the same version of a file, if the manifests of 2 and 3 have their order reversed, but the changelog did not, it could produce a filelog with linkrevs 0<-3 instead of 0<-2, which meant if commit 3 was stripped, it would delete that file data from the repository and commit 2 would be corrupt (as would any future pulls that tried to build upon that version of the file). The fix is to make the linkrev fixup smarter. Previously it considered the first manifest that added a file to be the first commit that added that file, which is not true. Now, for every file revision we add to the bundle we make sure we attach it to the earliest applicable linkrev.
