fsmonitor: use configitem We might as well get this out of the way. Differential Revision: https://phab.mercurial-scm.org/D893

fsmonitor: access copymap in new location fsmonitor has been busted since 0865d25e8a8a due to moving self._copymap. Fix it. Differential Revision: https://phab.mercurial-scm.org/D892

extdata: use subprocess so we don't have to chdir() manually

extdata: just use iterator to read lines one by one

extdata: ignore ambiguous identifier as well

templater: add experimental support for extdata This is minimal and non-controversial implementation of extdata() template function. Originally extdata sources were exposed to the keyword namespace, but I've changed it to a plain function for simplicity.

revset: add experimental support for extdata This is minimal and non-controversial implementation of extdata() revset. Originally extdata sources were exposed to the symbol namespace, but I've changed it to a plain function for simplicity.

extdata: add extdatasource reader This adds basic support for extdata, a way to add external data sources for revsets and templates. An extdata data source is simply a list of lines of the form: <revision identifier>[<space><freeform text>]\n An extdata source is configured thusly: [extdata] name = <a url or path> urls of the form shell: are launch shell commands to generate data. This patch is slightly modified by Yuya Nishihara as follows: - fix typo - remove unused function - remove future expansion point for parameter (which can be added later as the extdata revset/template are experimental) You can see the original patch at https://www.mercurial-scm.org/pipermail/mercurial-devel/2016-September/088426.html

tests: change to parent directory before all "hg init" in test-log.t Add a "cd .." before the second "hg init" so that all repositories are on top level of test directory. Makes inspection of test directory easier.

config: add a missing preparewrite() call Thanks Yuya for pointing this out in D808. Differential Revision: https://phab.mercurial-scm.org/D924

test-strip: make test compatible with chg The test was using reposetup which had the logic for stripping commits. This leads to a situation where if the reposetup was called twice for an extension (which can happen with chg running), the stripped node would not be found the second time. Therefore, this commit changes the test to put the stripping logic inside commands instead of the reposetup. This ensures that the stripping logic is invoked only when the command is invoked and thus, avoids any problems. Test Plan: Ran the test 'test-strip.t' with and without the '--chg' option. Differential Revision: https://phab.mercurial-scm.org/D928

test-hook: make test compatible with chg The test uses the 'print' method instead of writing to stdout using 'ui.write' which leads to incompatibility with chg. This commit modifies the test to use 'ui' instead which fixes the problem. Test Plan: Ran the test 'test-hook.t' with and without '--chg' option. Differential Revision: https://phab.mercurial-scm.org/D927

test-setdiscovery: make test compatible with chg The test checks the output of the blackbox extension which will contain logs corresponding to chg in case chg is running. Therefore, this commit modifies the test to take chg into consideration while working with the blackbox extension. Test Plan: Ran the test 'test-setdiscovery.t' with and without the '--chg' option. Differential Revision: https://phab.mercurial-scm.org/D926

test-merge-subrepos: make test compatible with chg The test checks the output of '.hg/blackbox.log' which will contain logs corresponding to chg in case chg is running. Therefore, this commit modifies the test to take chg into consideration while checking the blackbox.log contents. Test Plan: Ran the test 'test-merge-subrepos.t' with and without the '--chg' option. Differential Revision: https://phab.mercurial-scm.org/D925

test-convert-cvs: make test compatible with chg The test uses the 'print' method instead of writing to stdout using 'ui.write' which leads to incompatibility with chg. This commit modifies the test to use the 'ui' object instead which fixes the problem. Test Plan: Ran the test 'test-convert-cvs.t' with and without '--chg' option. Differential Revision: https://phab.mercurial-scm.org/D923

test-basic: make test compatible with chg The error codes returned when writing to /dev/full are different after the first failure with and without '--chg' option. Therefore, this commit conditionally handles the error codes as appropriate. Test Plan: Ran the test 'test-basic.t' with and without '--chg' option.

zeroconf: do not crash if socket being read is closed by another thread In zeroconf/__init__.py, there is: server = Zeroconf.Zeroconf(ip) l = listener() Zeroconf.ServiceBrowser(server, "_hg._tcp.local.", l) time.sleep(1) server.close() `server.close()` closes the underlying socket while the `ServiceBrowser` may still have a background thread reading the socket. There could be a race condition where the reading thread reads the closed socket, resulting in EBADF crash. This patch catches the exception. This makes test-paths.t pass with chg.

test-revlog-mmapindex: make it compatible with chg The test misses an explicit flush(). Differential Revision: https://phab.mercurial-scm.org/D918

test-profile: gate chg-incompatible part with '#if chg' chg has a different extension loading logic, which affects the profiler extension test case. Gate the block with '#if chg' so the test passes with chg. Differential Revision: https://phab.mercurial-scm.org/D916

test-logtoprocess: make it compatible with chg chg runs more commands and outputs more lines. This patch matches them. Differential Revision: https://phab.mercurial-scm.org/D914

test-globalopts: make the test compatible with chg The test fails when run with the '--chg' option. Therefore, this commit modifies the test to make it compatible with chg. Test Plan: Ran 'test-globalopts.t' with and without the '--chg' option. Differential Revision: https://phab.mercurial-scm.org/D913

test-pager: make it compatible with chg chg's runpager implementation is different. It behaves differently for the "shell=False, command not found" case. Differential Revision: https://phab.mercurial-scm.org/D911

changelog: use a Factory for default value for files The default value is compiled into the generated type. This means that default values are shared between instances. For immutable types like bool, str, int, and tuple, this is fine. But for mutable types like list and dict, we need to use attr.Factory() to instantiate a new instance of the default for each object.

cext: wrap before brace for functions This is our prevailing style. Differential Revision: https://phab.mercurial-scm.org/D910

cext: put case statements on separate line This seems to be the prevailing style, even though it is a bit more verbose for very simple switch statements. Differential Revision: https://phab.mercurial-scm.org/D909

cext: reorder #include We mostly abide by this style. In one case, a blank line was inserted to prevent a local `#include "file"` from coming before a `#include <file>`. Differential Revision: https://phab.mercurial-scm.org/D908

cext: move braces for control statements to same line This seems to be the prevailing style in the code by a wide margin. Differential Revision: https://phab.mercurial-scm.org/D907
