unionrepo: use pathutil.normasprefix to ensure os.sep at the end of cwd Since Python 2.7.9, "os.path.join(path, '')" doesn't add "os.sep" at the end of UNC path (see issue4557 for detail). This makes unionrepo incorrectly work, if: 1. cwd is the root of UNC share (e.g. "\host\share"), and 2. mainreporoot is near cwd (e.g. "\host\sharefoo\repo") - host of UNC path is same as one of cwd - share of UNC path starts with one of cwd 3. "repopath" isn't specified in URI (e.g. "union:path/to/repo2") For example: $ hg --cwd \host\share -R \host\sharefoo\repo incoming union:path\to\repo2 In this case: - os.path.join(r"\host\share", "") returns r"\host\share", - r"\host\sharefoo\repo".startswith(r"\host\share") returns True, then - r"foo\repo" is treated as repopath of unionrepo instead of r"\host\sharefoo\repo" This causes failure of combining "\host\sharefoo\repo" and another repository: in addition to it, "\host\share\foo\repo" may be combined with another repository, if it accidentally exists. This patch uses "pathutil.normasprefix()" to ensure "os.sep" at the end of cwd safely, even with some problematic encodings, which use 0x5c (= "os.sep" on Windows) as the tail byte of some multi-byte characters. BTW, normalization before "pathutil.normasprefix()" isn't needed in this case, because "os.getcwd()" always returns normalized one.

bundlerepo: use pathutil.normasprefix to ensure os.sep at the end of cwd Since Python 2.7.9, "os.path.join(path, '')" doesn't add "os.sep" at the end of UNC path (see issue4557 for detail). This makes bundlerepo incorrectly work, if: 1. cwd is the root of UNC share (e.g. "\host\share"), and 2. mainreporoot is near cwd (e.g. "\host\sharefoo\repo") - host of UNC path is same as one of cwd - share of UNC path starts with one of cwd 3. "repopath" isn't specified in bundle URI (e.g. "bundle:bundlefile" or just "bundlefile") For example: $ hg --cwd \host\share -R \host\sharefoo\repo incoming bundle In this case: - os.path.join(r"\host\share", "") returns r"\host\share", - r"\host\sharefoo\repo".startswith(r"\host\share") returns True, then - r"foo\repo" is treated as repopath of bundlerepo instead of r"\host\sharefoo\repo" This causes failure of combining "\host\sharefoo\repo" and bundle file: in addition to it, "\host\share\foo\repo" may be combined with bundle file, if it accidentally exists.

dirstate: use pathutil.normasprefix to ensure os.sep at the end of root 3cc630be5f09 replaced "os.path.join(root, '')" by "root.endswith(os.sep)" examination, because Python 2.7.9 changes behavior of "os.path.join(path, '')" on UNC path. But some problematic encodings use 0x5c (= "os.sep" on Windows) as the tail byte of some multi-byte characters, and replacement above prevents Mercurial from working on the repository, of which root path ends with such multi-byte character, regardless of enabling win32mbcs. This patch uses "pathutil.normasprefix()" instead of "root.endswith(os.sep)" examination, to ensure "os.sep" at the end of "dirstate._rootdir" even with problematic encodings. "root" of dirstate can be passed to "pathutil.normasprefix()" without normalization, because it is always given from "repo.root" = "repo.wvfs.base", which is normalized by "os.path.realpath()". Using "util.endswithsep()" instead of "str.endswith(os.sep)" also fixes this problem, but this patch chooses "pathutil.normasprefix()" to centralize "adding os.sep if endswith(os.sep)" logic into it.

histedit: fix rollup prompting for a commit message (issue4606) Commit 090da03361c5 broke histedit's rollup by causing it to open the editor. Turns out I missed a spot where the rollup option was read. This fixes that and adjusts the test to catch this case.

test-hook.t: don't directly use redirect to /dev/null in hook for Windows This goes with 57f1dbc99631. External hooks are run in cmd.exe, which doesn't know about /dev/null, but sh can handle it.

mq: avoid silent failure when single patch doesn't apply (issue4604) The error-handling here is quite byzantine. self._apply raises an AbortNoCleanup, but self.apply was swallowing the exception and returns 2. In self.push, we catch all exceptions.. and cleanup. We try to print a message to clean up.. but that relies on having a top-of-stack. Instead, we re-raise the abort in self.apply, and avoid cleanup on AbortNoCleanup in self.push by adding a trivial new except clause. We also modernize the now-visible abort message.
