Yuya Nishihara <yuya@tcha.org> [Wed, 11 Jul 2018 21:51:47 +0900] rev 38651
grep: add config knob to enable/disable the default wdir search This allows us to conditionally enable the new behavior to unbreak python-hglib. See the next patch. The config option is undocumented since the --all-files is still experimental and isn't fully implemented. It can be moved to [experimental] if that's preferred.

Wed, 11 Jul 2018 21:35:31 +0900 grep: search working directory files by default if --all-files is specified
Yuya Nishihara <yuya@tcha.org> [Wed, 11 Jul 2018 21:35:31 +0900] rev 38650
grep: search working directory files by default if --all-files is specified The default was -rtip:0 before, but "--all-files -rtip:0" would be the most useless combination, and it isn't supported yet. Let's change the default to something useful. This isn't flagged as BC since --all-files isn't released. Differential Revision: https://phab.mercurial-scm.org/D3917
Wed, 11 Jul 2018 21:23:18 +0900 grep: reject --diff --all-files
Yuya Nishihara <yuya@tcha.org> [Wed, 11 Jul 2018 21:23:18 +0900] rev 38649
grep: reject --diff --all-files This combination doesn't make any sense since --diff is the flag to search change history, whereas --all-files is to include unmodified contents. Differential Revision: https://phab.mercurial-scm.org/D3916
Wed, 11 Jul 2018 21:15:52 +0900 grep: rename --allfiles to --all-files
Yuya Nishihara <yuya@tcha.org> [Wed, 11 Jul 2018 21:15:52 +0900] rev 38648
grep: rename --allfiles to --all-files This matches the config name to be added. Note that we don't have to keep the old flag since it isn't released yet. Differential Revision: https://phab.mercurial-scm.org/D3915

debugdeltachain: protect against 0 readsize If you don't read any data, read density should be 1.
Thu, 21 Jun 2018 18:19:57 +0200 debugdeltachain: avoid division by zero when a chain is empty
Paul Morelle <paul.morelle@octobus.net> [Thu, 21 Jun 2018 18:19:57 +0200] rev 38646
debugdeltachain: avoid division by zero when a chain is empty The two ratios chainratio and extraratio are computed using dividers that may be zero when the file is empty. As the denominators are integers, the limit of the ratio "just before zero" is the numerator value itself. If the numerator itself is zero, the ratio value is still meaningful: in both cases, a "good" value is a low ratio, and a size of zero is the optimal case.

Danny Hooper <hooper@google.com> [Mon, 09 Jul 2018 15:33:49 -0700] rev 38645
tests: prevent conflict markers in test case from triggering warnings Broadly, having lines that begin with several '<' tends to trigger tools that try to warn you about unresolved conflicts. It will save some headaches to tweak this string literal to avoid that. Differential Revision: https://phab.mercurial-scm.org/D3897
Tue, 10 Jul 2018 12:20:57 +0200 revlog: enforce chunk slicing down to a certain size
Boris Feld <boris.feld@octobus.net> [Tue, 10 Jul 2018 12:20:57 +0200] rev 38644
revlog: enforce chunk slicing down to a certain size Limit maximum chunk size to 4x final size when reading a revision from a revlog. We only apply this logic when the target size is known from the revlog. Ideally, revlog's delta chain would be written in a way that does not trigger this extra slicing often. However, having this second guarantee that we won't read unexpectedly large amounts of memory in all cases is important for the future. Future delta chain building algorithms might have good reason to create delta chain with such characteristics. Including this code in core as soon as possible will make Mercurial 4.7 forward-compatible with such improvement.

Boris Feld <boris.feld@octobus.net> [Tue, 10 Jul 2018 11:57:33 +0200] rev 38643
revlog: postprocess chunk to slice them down to a certain size After the density slicing is done, we enforce a maximum chunk size to avoid memory consumption issue.
Wed, 11 Jul 2018 00:35:01 -0700 revlog: add function to slice chunk down to a given size
Boris Feld <boris.feld@octobus.net> [Wed, 11 Jul 2018 00:35:01 -0700] rev 38642
revlog: add function to slice chunk down to a given size It is possible to encounter situations where the slicing based on density did not achieve chunk smaller than the 4*textlength limit. To avoid extra memory consumption in those cases, we need to be able to break down chunk to a given size. Actual caller comes in the next changesets.
