tests: configure fsmonitor.mode=paranoid always if fsmonitor is used This forces fsmonitor extension execute "paranoid" code path. Strict speaking, we should make fsmonitor-run-tests.py accept own specific options, but there is no code path, which is disabled in "paranoid" mode, at least now. Therefore, this solution seems reasonable enough.

tests: drop files from exclusion list in test-check-module-imports.t Now, these files has no style issue at checking with import-checker.py. BTW, tests/test-imports-checker.t is still excluded, because almost all code fragments in it has intentional importing style violation. Using NO_CHECK_EOF instead of EOF as heredoc limit mark can make import-checker.py ignore such fragments. But keeping these fragments checkable seems still useful: for example, test-imports-checker.t can be used to test whether import-checker.py can detect erroneous code fragment in test script as expected.

tests: use NO_CHECK_EOF for fragments used to test importing via extension test-extension.t is excluded in test-check-module-imports.t, because import-checker.py reports that some python code fragments in it does not import modules in recommended style. These code fragments are used to test importing modules relatively and absolutely via extension (e.g. issue4029, issue5208, and so on). Test specific package hierarchy becomes complicated for this purpose, and it seems reasonable to avoid checking these code fragments with import-checker.py. But on the other hand, other code fragments in test-extension.t should be checked by import-checker.py. Therefore, this patch uses NO_CHECK_EOF limit mark only for python code fragments, which are used to test importing via extension in test-extension.t. NO_CHECK_EOF limit mark tells import-checker.py that this code fragment should be ignored, via testparseutil.py.

tests: use NO_CHECK_EOF for fragments having intentional error Some test scripts are excluded in test-check-module-imports.t, because import-checker.py reports that code fragments embedded in these test scripts have syntax error. But these syntax error is intentional. This patch uses NO_CHECK_EOF instead of EOF as heredoc limit mark for such fragments, in order to make import-checker.py ignore them. NO_CHECK_EOF limit mark tells import-checker.py that this code fragment should be ignored, via testparseutil.py.

tests: fix style issue of importing order in test-lock.py test-lock.py is excluded in test-check-module-imports.t, because import-checker.py reports that some stdlibs are imported after local silenttestrunner module. I can not found out any reason why tests/silenttestrunner.py should be imported before some stdlibs from the point of functionality view.

tests: fix style issue of importing hgweb in embedded code fragments Some test scripts are excluded in test-check-module-imports.t, because import-checker.py reports that hgweb and/or hgwebdir of mercurial.hgweb are not imported in recommended style. To fix this issues, this patch make python code fragments embedded in these files import hgweb from mercurial package at first, and refer hgweb and hgwebdir via imported hgweb.

py3: encode str to bytes These fields are str on Python 2 and 3. This module doesn't import any Mercurial modules. So I just did the str -> bytes inline. Differential Revision: https://phab.mercurial-scm.org/D5010

py3: sprinkle statprof.py with utf-8 encoding Trying to chase the long tail of unicode badness in this file due to frame / code objects holding str everywhere. Differential Revision: https://phab.mercurial-scm.org/D5016

py3: flush stdout This avoids buffering due to mixed print() and sys.stdout.write() by profiling code. And with this, test-profile.t passes on Python 3 \o/. Honestly, I'd be shocked if there weren't more Python 3 encoding issues lingering in the profiling code. That code isn't super high quality and doesn't seem to have thorough test coverage.

absorb: prompt user to accept absorb changes by default Change the default absorb behaviour to print the changes out and then prompt the user if they want to absorb the changes or not. Providing the `-p` option still prints the result and exits. A new `-a` option is provided which applies the changes without printing them, giving the equivalent of the old behaviour.

templatefuncs: add truncate parameter to pad Add a truncate option to pad that additionally truncates the text to the pad width if it is wider. Since color codes can cause a problem with this, when the text is truncated, the color codes are also stripped. Users of the truncate option should label the text outside the pad.

revlog: update pure nodecache start lookup offset on insertion test-storage.py is failing in pure builds because the population of the node cache isn't accounting for the new starting offset after a revlog insertion. This commit updates the node cache start offset to account for insertions. I'm not 100% convinced this is the ideal solution. But it works and seems correct.

exchangev2: use filesdata filesdata is a more efficient mechanism for bulk fetching files data for a range of changesets. Let's use it in exchangev2. With this change, a client performing a full clone of mozilla-unified transmits substantially fewer bytes across the wire: before: 139,124,863 bytes sent after: 20,522,499 bytes sent The bulk of the remaining bytes is likely the transfer of ~1M nodes for changesets and manifests. We can eliminate this by making requests in terms of node ranges instead of explicit node lists... Differential Revision: https://phab.mercurial-scm.org/D4982
