fetch: add trace2 instrumentation

2019-10-03T01:13:17Z

Add trace2 regions to fetch-pack.c and builtins/fetch.c to better track time spent in the various phases of a fetch: * listing refs * negotiation for protocol versions v0-v2 * fetching refs * consuming refs Signed-off-by: Josh Steadmon Signed-off-by: Junio C Hamano

fetch-pack: use parse_oid_hex

2019-08-19T22:04:57Z

Instead of hard-coding constants, use parse_oid_hex to compute a pointer and use it in further parsing operations. Signed-off-by: brian m. carlson Signed-off-by: Junio C Hamano

repo-settings: create feature.experimental setting

2019-08-13T20:33:55Z

The 'feature.experimental' setting includes config options that are not committed to become defaults, but could use additional testing. Update the following config settings to take new defaults, and to use the repo_settings struct if not already using them: * 'pack.useSparse=true' * 'fetch.negotiationAlgorithm=skipping' In the case of fetch.negotiationAlgorithm, the existing logic would load the config option only when about to use the setting, so had a die() statement on an unknown string value. This is removed as now the config is parsed under prepare_repo_settings(). In general, this die() is probably misplaced and not valuable. A test was removed that checked this die() statement executed. Signed-off-by: Derrick Stolee Signed-off-by: Junio C Hamano

Merge branch 'nd/fetch-capability-tweak'

2019-07-09T22:25:43Z

Protocol capabilities that go over wire should never be translated, but it was incorrectly marked for translation, which has been corrected. The output of protocol capabilities for debugging has been tweaked a bit. * nd/fetch-capability-tweak: fetch-pack: print server version at the top in -v -v fetch-pack: print all relevant supported capabilities with -v -v fetch-pack: move capability names out of i18n strings

list-objects-filter-options: make filter_spec a string_list

2019-06-28T15:41:53Z

Make the filter_spec string a string_list rather than a raw C string. The list of strings must be concatted together to make a complete filter_spec. A future patch will use this capability to build "combine:" filter specs gradually. A strbuf would seem to be a more natural choice for this object, but it unfortunately requires initialization besides just zero'ing out the memory. This results in all container structs, and all containers of those structs, etc., to also require initialization. Initializing them all would be more cumbersome that simply using a string_list, which behaves properly when its contents are zero'd. For the purposes of code simplification, change behavior in how filter specs are conveyed over the protocol: do not normalize the tree: filter specs since there should be no server in existence that supports tree:# but not tree:#k etc. Helped-by: Junio C Hamano Signed-off-by: Matthew DeVore Signed-off-by: Junio C Hamano

fetch-pack: print server version at the top in -v -v

2019-06-20T21:01:00Z

Before the previous patch, the server version is printed after all the "Server supports" lines. The previous one puts the version in the middle of "Server supports" group. Instead of moving it to the bottom, I move it to the top. Version may stand out more at the top as we will have even more debug out after capabilities.

fetch-pack: print all relevant supported capabilities with -v -v

2019-06-20T21:00:59Z

When we check if some capability is supported, we do print something in verbose mode. Some capabilities are not printed though (and it made me think it's not supported; I was more used to GIT_TRACE_PACKET) so let's print them all. It's a bit more code. And one could argue for printing all supported capabilities the server sends us. But I think it's still valuable this way because we see the capabilities that the client cares about.
