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.
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.
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.
util: fix the check for non-C99 compilers (

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.
pushkey: flush pending data before running a pre-pushkey hook (
issue4607)
The pre-pushkey hook will likely validate the pushkey based on element
previously changed in the same transaction. We need to make theses data
available for the hook.
