help: convert dict to strkwargs

util: use sysstr.join instead of bytes.join in textwrap wrapper

tests: port test extension in test-help.t to python 3 The changes required herein suggest to me that we should probably accept ascii-safe unicode strings for command name, flag name, etc.

doc: port check-seclevel.py to be Python 2/3 portable

match: define exactmatcher.matchfn statically This should eliminate the reference cycle, self.matchfn -> self.exact -> self.

match: remove override of prefix() from differencematcher It's exactly the same as basematcher.prefix().

cat: do not start pager if output will be written to file

cat: pass filename template as explicit argument I'll move the handling of the '-' filename to commands.cat().

cmdutil: extract function checking if pattern should be taken as stdin/out This will be used in commands.cat().

cmdutil: drop deprecated hack to pass file object to makefileobj() (API) All callers pass a string 'pat' or None.

encoding: make sure "wide" variable never be referenced from other modules Better to not expose (maybe-) unicode objects.

manifest: use itertools.chain() instead of + for Python 3 compat This is all pure-Python code, so I'm not too worried about perf here, but we can come back and fix it should it be a problem. With this change, the manifest code passes most unit tests on Python 3 (once the tests are corrected with many b prefixes. I've got a little more to sort out there and then I'll mail that change too.

manifest: fix some pure-Python parser bits to work on Python 3

tests: make test-manifest finish importing in Python 3 The test is still broken, but now it executes.

tests: drop assertIn polyfill now that we're 2.7-only

perf: benchmark command for revlog indexes We didn't have explicit microbenchmark coverage for loading revlog indexes. That seems like a useful thing to have, so let's add it. We currently measure the low-level nodemap APIs. There is room to hook in at the actual revlog layer. This could be done as a follow-up. The hackiest thing about this patch is specifying revlog paths. Other commands have arguments that allow resolution of changelog, manifest, and filelog. I needed to hook in at a lower level of the revlog API than what the existing helper functions to resolve revlogs allowed. I was too lazy to write some new APIs. This could be done as a follow-up easily enough.

perf: rename perfrevlog to perfrevlogrevisions We have a couple of commands beginning with "perfrevlog." The actual "perfrevlog" command actually measures resolving the fulltext of multiple revisions. So let's rename it to reflect what it actually does.

server: use pycompat to get argv

encoding: make wide character class list a sysstr That's what east_asian_width returns, so just match it.

cmdutil: use sorted(dict) instead of x = dict.keys(); x.sort() The former both does less work and has the virtue of working on Python 3.

util: look for empty-sysstr instead of empty-bytesstr in textwrap code Fixes behavior on Python 3.

minirst: look for column delimiters using slices instead of indicies This works on both Python 2 and 3.

minirst: grab a byte, not an int, for the underline style

minirst: use bytes.strip instead of str.strip

py3: use pycompat.bytestr so that we don't get ascii values This fixes `hg files 'set:(**.py)'` which makes test-check-py3-compat.t able to run on Python 3. So if you now do `python3 ./run-tests.py test-check-py3-compat`, the test will actually run.

py3: update test-check-py3-compat.t

loader: pywatchman appears to already be py3 compatible Our loader was doing some confusing things in pywatchman, but it looks like we shouldn't be using it there anyway.

py3: update test expectations for py3-commands test

context: do not cache manifestctx This will make sure when ctx.repo.manifestlog changes, a correct new manifestctx is returned. repo.manifestlog takes care of caching so the manifestctx won't be reconstructed every time.

test-context: add a case demonstrating manifest caching problem This issue was discovered when testing absorb on Windows. What happens are: 1. ctx.p1().manifestctx gets cached. let's call ctx.p1().manifestctx._revlog() "mrevlog1" 2. repo.manifestlog gets invalidated. let's call repo.manifestlog._revlog "mrevlog2" 3. repo.commitctx(ctx) commitctx uses ctx.p1().manifestctx and writes to "mrevlog1" 4. repo[n].manifest() cannot find the manifest node in "mrevlog2" This patch adds a test case to reproduce the issue.

debugbundle: display the content of obsmarkers parts We parse and display the markers in the part when possible.

bundle: add an experimental knob to include obsmarkers in bundle The "hg bundle" command is a good place to test if the inclusion of obsmarkers within a bundle is working well (part exists, content is correct etc). So we add a way to have them included. Ideally, this would be controlled by a change around bundlespec (bundlespec "v3" + arguments). However, my main goal is to have obsmarkers included in bundle created by the 'hg strip' command, not the 'hg bundle' so for now I'm avoiding the detour through bundlespec rework territory. Better debug output for obsmarkers in 'debugbundle' will be added in later changesets. The 'test-obsolete-bundle-strip.t' test will also get updated in a later changeset to keep the current changeset smaller.
