chg: define _GNU_SOURCE to allow CentOS 5 compilation Without this flag, compilation fails with: hgclient.c: In function 'hgc_open': hgclient.c:466: error: 'O_DIRECTORY' undeclared (first use in this function) hgclient.c:466: error: (Each undeclared identifier is reported only once hgclient.c:466: error: for each function it appears in.)

centos5: use vault urls CentOS 5 has reached end-of-life. A working build for it is still possible using 'vault.centos.org'. Differential Revision: https://phab.mercurial-scm.org/D261

ui: make sure buffer is flushed before waiting for user input (issue5587) Without this patch on Windows 'hg ci -i' hangs waiting for user input and "examine changes to 'file'? [Ynesfdaq?]" is never displayed (at least if the diff is sufficiently small). When Ctrl+C is pressed, this prompt becomes visible, which suggests that the buffer just wasn't flushed. I've never seen this happening on Linux, but this looks harmless enough to not platform-gate it.

util: fix sortdict.update() to call __setitem__() on PyPy (issue5639) It appears that overriding __setitem__() doesn't work as documented on PyPy. Let's patch it as before bd0fd3ff9916. https://docs.python.org/2/library/collections.html#ordereddict-examples-and-recipes The issue was ui.configitems() wasn't ordered correctly, so the pull command was wrapped in different order.

test-revlog-raw: close file handles explicitly (issue5644)

tests: clear __pycache__ for PyPy compatibility (issue5638) (issue5642)

test-extension: glob module name in error message for PyPy

rebase: sort collapsed revisions in commit message (issue5643) This fixes the test instability.

i18n: use actual filename, in which function is defined, for hg.pot Before this patch, source filename for msgid in hg.pot file becomes incorrect, if a function is defined in file A, but detected in dict in file B, For example, almost all debug* commands are defined in debugcommands.py, but hggettext detects them in "table" of commands.py. Therefore, docstring fragments of debug* commands are marked as "defined in commands.py" in hg.pot file. This is serious problem for translation, because the cost to find out original location of texts increases very much.

ui: enable pager always for explicit --pager=on (issue5580) Before this patch, explicit --pager=on is unintentionally ignored by any disabling factor, even if priority of it is less than --pager=on (e.g. "[ui] paginate = off").
