status: don't crash if a lookup file disappears This can happen if another process (even another hg process!) comes along and removes the file at that time. This partly resolves issue5584, but not completely -- a bogus dirstate update can still happen. However, the full fix is too involved for stable.

help: clarify the choice of pager This follows the change made in d83e51654c8a to use environment variables between system and user configuration.

zsh_completion: install as _hg not hg The contrib/zsh_completion file itself says to name it _hg. With a name like `hg`, if the user has a line like `autoload ${^fpath}/*(N-.:t)` in their zshrc, it will create a shell function named `hg` that will hide the actual hg command and make hg unusable. Separately from that though, the underscore prefix makes it actually work. The zsh man page states: The convention for autoloaded functions used in completion is that they start with an underscore This does not seem to just be a "convention", though. With the ill-advised line removed from my zshrc and the file named `/usr/local/share/zsh/site-functions/hg` (without the underscore), these completions did not seem to get loaded and the ones from the zsh installation were loaded instead. If I renamed them to be `/usr/local/share/zsh/site-functions/_hg`, however, they were loaded. I manually tested the above statement by starting a new zsh instance with the file in `/usr/local/share/zsh/site-functions` with the following names: - As `hg`, `which _hg_labels` did not show anything - As `_hg`, `which _hg_labels` showed the expected function.

osx: override default exclude filter for pkgbuild To quote `man 1 pkgbuild`: --filter filter-expression By default, --root will include the entire contents of the given root-path in the package payload, except for any .svn or CVS directories, and any .DS_Store files. You can override these default filters by specifying one or more --filter options. Each filter-expression is an re_format(7) ``extended'' expression: any path in the root which matches any of the given expressions will be excluded from the pack- age payload. (Note that specifying even one --filter inhibits the default filters, so you must respecify the default fil- ters if you still want them to be used.) It turns out the default filter these days *also* includes .git and .hg. Notice how that filter expression is a regular expression? That (presumably unintentionally) prevents a file named "chg" or "_hg" from getting included in the distribution. Many many thanks to spectral@ for trying to include a _hg file which led us to figure this bug out. Bug filed with Apple for this as rdar://problem/32437369, mentioning both the gap in documentation and the wrong defaults.

win32mbcs: avoid unintentional failure at colorization Since 176ed32dc159, pycompat.bytestr() wrapped by win32mbcs returns unicode object, if an argument is not byte-str object. And this causes unexpected failure at colorization. pycompat.bytestr() is used to convert from color effect "int" value to byte-str object in color module. Wrapped pycompat.bytestr() returns unicode object for such "int" value, because it isn't byte-str. If this returned unicode object is used to colorize non-ASCII byte-str in cases below, UnicodeDecodeError is raised at an operation between them. - colorization uses "ansi" color mode, or Even though this isn't default on Windows, user might use this color mode for third party pager. - ui.write() is buffered with labeled=True Buffering causes "ansi" color mode internally, regardless of actual color mode. With "win32" color mode, extra escape sequences are omitted at writing data out. For example, with "win32" color mode, "hg status" doesn't fail for non-ASCII filenames, but "hg log" does for non-ASCII text, because the latter implies buffered formatter. There are many "color effect" value lines in color.py, and making them byte-str objects isn't suitable for fixing on stable. In addition to it, pycompat.bytestr will be used to get byte-str object from any types other than int, too. To resolve this issue, this patch does: - replace pycompat.bytestr in checkwinfilename() with newly added hook point util._filenamebytestr, and - make win32mbcs reverse-wrap util._filenamebytestr (this is a replacement of 176ed32dc159) This patch does two things above at same time, because separately applying the former change adds broken revision (from point of view of win32mbcs) to stable branch. "_" prefix is added to "filenamebytestr", because it is win32mbcs specific hook point.

debian: add less as a build dependency For builds that run on hermetic environments, it's possible that the "less" package is not installed by default, yet it's needed for tests to pass after revision bf5e13e38390 (which sets less as the fallback pager).

wix: add 'ro' and 'ru' locales Also noticed when diffing an MSI installation against an Inno installation. OTOH, the Inno install doesn't include 'i18n' with the *.po files.

wix: include zstd.pyd in the installation When trying to create a zstd bundle, the MSI based install said: abort: compression engine zstd could not be loaded The Inno installer is unaffected. The name will need to be updated to include 'cext' when merging into default.

clonebundles: fix missing newline character Previously, the line displayed as '( )' instead of '(\n)'.

exchange: print full reason variable This commit essentially reverts 69ac9aebbc55. urllib2.URLError receives a "reason" argument. It isn't always a tuple. Mozilla has experienced at least IndexError failures due to the reason[1] access. https://bugzilla.mozilla.org/show_bug.cgi?id=1364687

dispatch: setup color before pager for correct console information on windows Before this patch, "hg CMD --pager on" on Windows shows output unintentionally decorated with ANSI color escape sequences, if color mode is "auto". This issue occurs in steps below. 1. dispatch() invokes ui.pager() at detection of "--pager on" 2. stdout of hg process is redirected into stdin of pager process 3. "ui.formatted" = True, because isatty(stdout) is so before (2) 4. color module is loaded for colorization 5. color.w32effects = None, because GetConsoleScreenBufferInfo() fails on stdout redirected at (2) 6. "ansi" color mode is chosen, because of "not w32effects" 7. output is colorized in "ansi" mode because of "ui.formatted" = True Even if "ansi" color mode is chosen, ordinarily redirected stdout makes ui.formatted() return False, and colorization is avoided. But in this issue case, "ui.formatted" = True at (3) forces output to be colorized. For correct console information on win32, it is needed to ensure that color module is loaded before redirection of stdout for pagination. BTW, if any of enabled extensions has "colortable" attribute, this issue is avoided even before this patch, because color module is imported as a part of loading such extension, and extension loading occurs before setting up pager. For example, mq and keyword have "colortable".

obsolete: invalidate "volatile" set cache after merging marker Adding markers to the repository might affect the set of obsolete changesets. So we most remove the "volatile" set who rely in that data. We add two missing invalidations after merging markers. This was caught by code change in the evolve extensions tests. This issues highlight that the current way to do things is a bit fragile, however we keep things simple for stable.

win32mbcs: wrap underlying pycompat.bytestr to use checkwinfilename safely win32mbcs wraps some functions, to prevent them from unintentionally treating backslash (0x5c), which is used as the second or later byte of multi bytes characters by problematic encodings, as a path component delimiter on Windows platform. This wrapping assumes that wrapped functions can safely accept unicode string arguments. Unfortunately, d1937bdcee8c broke this assumption by introducing pycompat.bytestr() into util.checkwinfilename() for py3 support. After that, wrapped checkwinfilename() always fails for non-ASCII filename at pycompat.bytestr() invocation. This patch wraps underlying pycompat.bytestr() function to use util.checkwinfilename() safely. To avoid similar regression in the future, another patch series will add smoke testing on default branch.

graft: fix graft across merges of duplicates of grafted changes Graft used findmissingrevs to find the candidates for graft duplicates in the destination. That function operates with the constraint: 1. N is an ancestor of some node in 'heads' 2. N is not an ancestor of any node in 'common' For our purpose, we do however have to work correctly in cases where the graft set has multiple roots or where merges between graft ranges are skipped. The only changesets we can be sure doesn't have ancestors that are grafts of any changeset in the graftset, are the ones that are common ancestors of *all* changesets in the graftset. We thus need: 2. N is not an ancestor of all nodes in 'common' This change will graft more correctly, but it will also in some cases make graft slower by making it search through a bigger and unnecessary large sets of changes to find duplicates. In the general case of grafting individual or linear sets, we do the same amount of work as before.

graft: test coverage of grafts and how merges can break duplicate detection This demonstrates unfortunate behaviour: extending the graft range cause the graft to behave differently. When the graft range includes a merge, we fail to detect duplicates that are ancestors of the merge.
