tests: convert directory separators to '/' for MSYS in test-check-py-compat This is the same fix as 8c1d7a0e737b.

tests: make `pwd` URL compatible on Windows in test-default-push Without this, the test fails with: $ hg -q commit -A -m 'add pushurl' abort: file:// URLs can only refer to localhost $ hg push abort: file:// URLs can only refer to localhost The variable $PWD causes check-code to complain, so avoid that.

windows: correct the import of win32 This module is relative, and was overlooked when converting to absolute_import in 6daa795ed32f.

win32: add internals help topics to Inno Setup installer

changegroups: add documentation for cg3

changegroup: add flags field to cg3 delta header This lets revlog flags be transmitted over the wire. Right now this is useful for censored nodes and for narrowhg's ellipsis nodes.

changegroup: introduce cg3, which has support for exchanging treemanifests I'm not entirely happy with using a trailing / on a "file" entry for transferring a treemanifest. We've discussed putting some flags on each file header[0], but I'm unconvinced that's actually any better: if we were going to add another feature to the cg format we'd still be doing a version bump anyway to cg4, so I'm inclined to not spend time coming up with a more sophisticated format until we actually know what the next feature we want to stuff in a changegroup will be. Test changes outside test-treemanifest.t are only due to the new CG3 bundlecap showing up in the wire protocol. Many thanks to adgar@google.com and martinvonz@google.com for helping me with various odd corners of the changegroup and treemanifest API. 0: It's not hard refactoring, nor is it a lot of work. I'm just disinclined to do speculative work when it's not clear what the customer would actually be.

revlog: seek to end of file before writing (issue4943) Revlogs were recently refactored to open file handles in "a+" and use a persistent file handle for reading and writing. This drastically reduced the number of file handles being opened. Unfortunately, it appears that some versions of Solaris lose the file offset when performing a write after the handle has been seeked. The simplest workaround is to seek to EOF on files opened in a+ mode before writing to them, which is what this patch does. Ideally, this code would exist in the vfs layer. However, this would require creating a proxy class for file objects in order to provide a custom implementation of write(). This would add overhead. Since revlogs are the only files we open in a+ mode, the one-off workaround in revlog.py should be sufficient. This patch appears to have little to no impact on performance on my Linux machine.

manifestmerge: have manifest do matching before diffing This means that the diff code does less work, potentially significantly less in the case of treemanifests. It also should ease implementation with narrowed clone cases (such as narrowhg) when we don't always have the entire set of treemanifest revlogs locally. As far as I can tell, this codepath is currently only used by record, so it'll probably die in the near future, and then narrowhg won't have to worry about composing with some unknown matching system.

branch: reword help text We're not necessarily talking about *the* active branch, just any old branch.

archive: adjust help text

annotate: add missing period to help

addremove: make help match add

add: mention .hgignore in help

bundle: warn for --base with --all

bundle: fix error for --all with destination Before it complained about --base

bundle: fix grammar in help text

bundle: clarify help text The file might not be compressed; the interactions between -a, --base, and a named or default repository weren't clear.

cmdutil: do not duplicate stdout by makefileobj() It made output order unpredictable because two separate buffers are flushed individually. Let's use a thin wrapper that just sends close() to black hole.

cmdutil: reimplement file wrapper that disables close() There's no need to dynamically create wrappedfileobj class and define close() as lambda. Also, __iter__() was missing.

export: remove useless comparison between file object and string It was introduced at 31aa2e5b0750, where "template" argument could be a file object. After that, a306837f8c87 added "len(template)", so "template" must be a string now. Therefore, "fp != template" should always be True. It seems 31aa2e5b0750 was intended to work around a bug in TortoiseHg, and I'm sure I've fixed it completely in TortoiseHg source. https://selenic.com/pipermail/mercurial-devel/2011-February/028467.html

export: do not print '<fdopen>' as an output filename Because makefileobj() duplicates or wraps stdout, "fp != sys.stdout" didn't work correctly. Python doc states that special file objects are named in the form '<...>', and absolute filenames should never start with '<', we can ignore names start with '<'. We can't test fp.fileno() because fp may be a command-server channel. https://docs.python.org/2.7/library/stdtypes.html#file.name In the test output, "exporting patch:" line is printed after patch content. This is caused by fdopen() and will be fixed by the subsequent patch.

commandserver: implement name() to clarify channel is not a plain file Because unknown attributes are delegated to the underlying file object, commandserver channels said they were '<stdout>' or '<stdin>' even though they weren't. This patch makes them say '<X-channel>'.

histedit: delete to drop The default behaviour to forbid this makes a lot of sense for novice users because it's safeguarding them from dangerous behavior but making it configurable will be apprieciated by power users in at least one big organization. It allows an user to look an histedit rules from declarative perspective and make the rules reflect the state after histedit. If we can move lines t move commits why can't we drop lines to drop commits? Let's put this behind config knob and inform users about this feature the very moment they are trying to use it so they can choose desired behaviour.
