rebase: simplify documentation about selecting commits to rebase

rebase: simplify documentation about public commits add reference to graft

verify: clean up weird error/warning lists Nested functions in Python are not able to assign to variables in the outer scope without something like the list trick because assignments refer to the inner scope. So, we formerly used a list to give an object to assign into. Now that error and warning are object members, the [0] hack is no longer needed.

diff: clarify comparison as first parent

histedit: add progress support

verify: remove unreachable code to reraise KeyboardInterrupt KeyboardInterrupt should never be caught as it doesn't inherit Exception in Python 2.5 or later. And if it was, "interrupted" would be printed twice. https://docs.python.org/2.7/library/exceptions.html#exception-hierarchy

verify: move exc() function onto class This is part of an effort to make verify more modular so extensions can hook into it.

verify: move err() to be a class function This is part of an effort to make it easier for extensions to hook into verify.

verify: move warn() to a class level function This is part of the effort to make verify more modular so extensions can hook into it more easily.

verify: move fncachewarned up to a class variable This is part of making verify more modular so hooks can extend it.

verify: move widely used variables into class members This will allow us to start moving some of the nested functions inside verify() out onto the class. This will allow extensions to hook into verify more easily.

verify: move verify logic into a class In order to allow extensions to hook into the verification logic more easily, we need to refactor it into multiple functions. The first step is to move it to a class so the shared state can be more easily accessed.

test-install: perform the wix checking on wdir() instead of "." This allows catching problems before they are committed.

revlog: fix bad indentation (replace tab by space)

log: speed up hg log <file|folder> This patch makes hg log <file|folder> faster by using changelog.readfiles instead of changelog.read. On our large repos for hg log <file|folder> -l5 operations that were taking: - ~8s I see a 25% improvement - ~15s, I see a 35% improvement For recently modified folder/file, the difference is negligible as we don't have to consider many revisions.

changelog: add a new method to get files modified by a changeset This patch adds a new method "readfiles" to get the files modified by a changeset. It extracts some logic from "read" to only return the files modified by a changeset as efficiently as possible. This is used in the next patch to speed up hg log <file|folder>

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.
