fncache: clean up fncache during strips
Previously the fncache was cleaned up at read time by noticing when it was out
of sync. This caused writes to happen outside the scope of transactions and
could have caused race conditions. With this change, we'll keep the fncache
up-to-date as we go by removing old entries during repair.strip.

2 files. |
| 14686 | 3 |
| 4 Like other file patterns, this pattern type is indicated by a prefix, | |
| 5 'set:'. The language supports a number of predicates which are joined | |
| 6 by infix operators. Parenthesis can be used for grouping. | |
| 7 | |
| 8 Identifiers such as filenames or patterns must be quoted with single | |
| 9 or double quotes if they contain characters outside of | |
| 10 ``[.*{}[]?/\_a-zA-Z0-9\x80-\xff]`` or if they match one of the | |
| 11 predefined predicates. This generally applies to file patterns other | |
| 12 than globs and arguments for predicates. | |
| 13 | |
| 14 Special characters can be used in quoted identifiers by escaping them, | |
| 15 e.g., ``\n`` is interpreted as a newline. To prevent them from being | |
| 16 interpreted, strings can be prefixed with ``r``, e.g. ``r'...'``. | |
| 17 | |
| 18 There is a single prefix operator: | |
| 19 | |
| 20 ``not x`` | |
| 21 Files not in x. Short form is ``! x``. | |
| 22 | |
| 23 These are the supported infix operators: | |
| 24 | |
| 25 ``x and y`` | |
| 26 The intersection of files in x and y. Short form is ``x & y``. | |
| 27 | |
| 28 ``x or y`` | |
| 29 The union of files in x and y. There are two alternative short | |
| 30 forms: ``x | y`` and ``x + y``. | |
| 31 | |
| 32 ``x - y`` | |
| 33 Files in x but not in y. | |
| 34 | |
| 35 The following predicates are supported: | |
| 36 | |
| 37 .. predicatesmarker | |
| 38 | |
| 39 Some sample queries: | |
| 40 | |
| 41 - Show status of files that appear to be binary in the working directory:: | |
| 42 | |
| 43 hg status -A "set:binary()" | |
| 44 | |
| 45 - Forget files that are in .hgignore but are already tracked:: | |
| 46 | |
| 47 hg forget "set:hgignore() and not ignored()" | |
| 48 | |
| 49 - Find text files that contain a string:: | |
| 50 | |
| 51 hg locate "set:grep(magic) and not binary()" | |
| 52 | |
| 53 - Find C files in a non-standard encoding:: | |
