2018-10-16Merge branch 'jn/gc-auto'Libravatar Junio C Hamano1-1/+2
"gc --auto" ended up calling exit(-1) upon error, which has been corrected to use exit(1). Also the error reporting behaviour when daemonized has been updated to exit with zero status when stopping due to a previously discovered error (which implies there is no point running gc to improve the situation); we used to exit with failure in such a case. * jn/gc-auto: gc: do not return error for prior errors in daemonized mode

2018-10-11ieot: add Index Entry Offset Table (IEOT) extensionLibravatar Ben Peart1-0/+18
This patch enables addressing the CPU cost of loading the index by adding additional data to the index that will allow us to efficiently multi- thread the loading and conversion of cache entries. It accomplishes this by adding an (optional) index extension that is a table of offsets to blocks of cache entries in the index file. To make this work for V4 indexes, when writing the cache entries, it periodically "resets" the prefix-compression by encoding the current entry as if the path name for the previous entry is completely different and saves the offset of that entry in the IEOT. Basically, with V4 indexes, it generates offsets into blocks of prefix-compressed entries. Signed-off-by: Ben Peart <benpeart@microsoft.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2018-10-11config: add new index.threads config settingLibravatar Ben Peart1-0/+7
Add support for a new index.threads config setting which will be used to control the threading code in do_read_index(). A value of 0 will tell the index code to automatically determine the correct number of threads to use. A value of 1 will make the code single threaded. A value greater than 1 will set the maximum number of threads to use. For testing purposes, this setting can be overwritten by setting the GIT_TEST_INDEX_THREADS=<n> environment variable to a value greater than 0.

2018-10-11eoie: add End of Index Entry (EOIE) extensionLibravatar Ben Peart1-0/+23
The End of Index Entry (EOIE) is used to locate the end of the variable length index entries and the beginning of the extensions. Code can take advantage of this to quickly locate the index extensions without having to parse through all of the index entries. The EOIE extension is always written out to the index file including to the shared index when using the split index feature. Because it is always written out, the SHA checksums in t/t1700-split-index.sh were updated to reflect its inclusion. It is written as an optional extension to ensure compatibility with other git implementations that do not yet support it. It is always written out to ensure it is available as often as possible to speed up index operations. Because it must be able to be loaded before the variable length cache entries and other index extensions, this extension must be written last. The signature for this extension is { 'E', 'O', 'I', 'E' }. The extension consists of: - 32-bit offset to the end of the index entries - 160-bit SHA-1 over the extension types and their sizes (but not their contents). E.g. if we have "TREE" extension that is N-bytes long, "REUC" extension that is M-bytes long, followed by "EOIE", then the hash would be: SHA-1("TREE" + <binary representation of N> + "REUC" + <binary representation of M>) Signed-off-by: Ben Peart <benpeart@microsoft.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2018-09-29config.txt: correct the note about uploadpack.packObjectsHookLibravatar Nguyễn Thái Ngọc Duy1-4/+4
Document for uploadpack.packObjectsHook is added in [1] and consists of two paragraphs, the second one is quite important about where this variable can stay. When the paragraph about uploadpack.allowFilter is added in [2], it's added in between the two paragraphs. This makes the "this is non-repo level config" note incorrectly apply to allowFilter instead of packObjectsHook. Move allowFilter paragraph down to fix this.

2018-09-27git-commit-graph.txt: refer to "*commit*-graph file"Libravatar Martin Ågren1-6/+6
This document sometimes refers to the "commit-graph file" as just "the graph file". This saves a couple of words here and there at the risk of confusion. In particular, the documentation for `git commit-graph read` appears to suggest that there are indeed different types of graph files. Let's just write out the full name everywhere. The full name, by the way, is not the dash-less "commit graph file". Use the dashed form. (The next commit will fix the remaining few instances of the "commit graph file" in this document.)
