hgweb: make .info a block element by default Using a <div> instead of a <span> with "display: block" makes more sense. While at it, let's adjust top margin in monoblue so that text in .info doesn't overlap changeset "tags" elements (they are quite large in monoblue).

revlog: don't use slicing to return parents This is the only place we use a slice on index entries, which are currently tuples. In preparation for moving away from tuples, let's stop using slices so we don't have to implement that support on the new type. We also tweak the logic slightly so the exception only catches the IndexError on the index lookup, not on the index entry lookup. The old code should never have been buggy. But it was semantically wrong. Differential Revision: https://phab.mercurial-scm.org/D1764

tests: switch test from '--config ui.editor=~/foo' to HGEDITOR=~/foo The test is currently not testing anything, the '--config ui.editor=~/path' argument is apparently of lower priority than the HGEDITOR that run-tests.py is setting. Differential Revision: https://phab.mercurial-scm.org/D1809

revert: support reverting to hidden cset if directaccess config is set This patch adds support for reverting files to a hidden changeset if `experimental.directacess=True` is set. Differential Revision: https://phab.mercurial-scm.org/D1763

update: support updating to hidden cset if directaccess config is set This patch adds support for updating to a hidden changeset without using --hidden if `experimental.directacces=True` is set. The update command will print out a warning when updating to a hidden changeset saying: `updating to a hidden changeset <hash>` The warning is also printed when directaccess is not used and --hidden is passed which I think is good behaviour. Tests are added for the directaccess part and updated output of tests which have case of updating to hidden cset using `--hidden`. Differential Revision: https://phab.mercurial-scm.org/D1762

test-convert-cvs: change TZ=US/Hawaii to TZ=Pacific/Johnston The former was limited to be known on Linux and the test failed on FreeBSD and Solaris platforms. The newer is known on Linux, FreeBSD and Solaris.

osutil: implement getfsmountpoint() on BSD systems I don't have a BSD system handy to test this, but it looks simple enough from the man page.

debugfs: display the tested path and mount point of the filesystem, if known While implementing win32.getfstype(), I noticed that MSYS path mangling is getting in the way. Given a path \\host\share\dir: - If strong quoted, hg receives it unchanged, and it works as expected - If double quoted, it converts to \host\share\dir - If unquoted, it converts to \hostsharedir The second and third cases are problematic because those are valid paths relative to the current drive letter, so os.path.realpath() will expand it as such. The net effect is to silently turn a network path test into (typically) a "C:\" test. Additionally, the command hangs after printing out 'symlink: no' for the third case (but is interruptable with Ctrl + C). This path mangling only comes into play because of the command line arguments- it won't affect internally obtained paths. Therefore, the simplest thing to do is to provide feedback on what the command is acting on. I also added the mount point, because Windows supports nesting [1] volumes (see the examples in "Junction Points and Mounted Folders"), and it was a useful diagnostic for figuring out why the wrong filesystem was printed out in the cases above. I opted not to call os.path.realpath() on the path argument, to make it clearer that the mangling isn't being done by Mercurial.

util: add a function to show the mount point of the filesystem For now, this is Windows only, since Linux doesn't have the value in its statfs structure, and I don't have a BSD system to test with.

win32: split a utility function to obtain the volume out of getfstype() This is only done on Windows because it's simple enough to call statfs() on Unix. The goal is to display this in `hg debugfs`.

util: whitelist NTFS for hardlink creation (issue4580)

win32: implement util.getfstype() This will allow NTFS to be added to the hardlink whitelist, and resume creating hardlinks in transactions (which was disabled globally in 07a92bbd02e5; see also e5ce49a30146). I opted to report "cifs" for remote volumes because this shows in `hg debugfs`, which also reports that hardlinks are supported for these volumes. So being able to distinguish it from "unknown" seems useful. The documentation [1] seems to indicate that SMB isn't supported by these functions, but experimenting shows that mapped drives are reported as "NTFS" on Windows 7. I don't have a second Windows machine, but instead shared a temp directory on C:\. In this setup, both of the following were detected as 'cifs' with the explicit GetDriveType() check: Z:\repo>hg ci -A C:\>hg -R \\hostname\temp\repo ci -A # (without Z:\ being mapped) It looks like this is called 6 times to add and commit a single new file, so I'm a little surprised this isn't cached.

util: move getfstype() to the platform modules This makes room for implementing on Windows using ctypes.

graphlog: add another graph node type, unstable, using character "*" (BC)
