2017-03-01read-cache: regenerate shared index if necessaryLibravatar Christian Couder2-0/+33
When writing a new split-index and there is a big number of cache entries in the split-index compared to the shared index, it is a good idea to regenerate the shared index. By default when the ratio reaches 20%, we will push back all the entries from the split-index into a new shared index file instead of just creating a new split-index file. The threshold can be configured using the "splitIndex.maxPercentChange" config variable. We need to adjust the existing tests in t1700 by setting "splitIndex.maxPercentChange" to 100 at the beginning of t1700, as the existing tests are assuming that the shared index is regenerated only when `git update-index --split-index` is used.

2017-03-01update-index: warn in case of split-index incoherencyLibravatar Christian Couder1-1/+10
When users are using `git update-index --(no-)split-index`, they may expect the split-index feature to be used or not according to the option they just used, but this might not be the case if the new "core.splitIndex" config variable has been set. In this case let's warn about what will happen and why. Signed-off-by: Christian Couder <chriscool@tuxfamily.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2016-12-21Merge branch 'jk/quote-env-path-list-component'Libravatar Junio C Hamano5-12/+102
A recent update to receive-pack to make it easier to drop garbage objects made it clear that GIT_ALTERNATE_OBJECT_DIRECTORIES cannot have a pathname with a colon in it (no surprise!), and this in turn made it impossible to push into a repository at such a path. This has been fixed by introducing a quoting mechanism used when appending such a path to the colon-separated list. * jk/quote-env-path-list-component: t5615-alternate-env: double-quotes in file names do not work on Windows t5547-push-quarantine: run the path separator test on Windows, too tmp-objdir: quote paths we add to alternates alternates: accept double-quoted paths

2016-12-20mailinfo.c: move side-effects outside of assertLibravatar Kyle J. McKay1-1/+2
Since 6b4b013f18 (mailinfo: handle in-body header continuations, 2016-09-20, v2.11.0) mailinfo.c has contained new code with an assert of the form: assert(call_a_function(...)) The function in question, check_header, has side effects. This means that when NDEBUG is defined during a release build the function call is omitted entirely, the side effects do not take place and tests (fortunately) start failing. Since the only time that mi->inbody_header_accum is appended to is in check_inbody_header, and appending onto a blank mi->inbody_header_accum always happens when is_inbody_header is true, this guarantees a prefix that causes check_header to always return true. Therefore replace the assert with an if !check_header + DIE combination to reflect this.
