I'm not sure what exactly causes this issue and why it's an issue only with this particular header, but all headers in 'protocol-v2.txt' are written like this: Initial Client Request ------------------------ i.e. the header itself is indented by a space, and the "underline" is two characters longer than the header. Dropping that indentation and making the length of the underline match the length of the header apparently fixes this issue.

2019-03-22trace2: write to directory targetsLibravatar Josh Steadmon1-0/+5
When the value of a trace2 environment variable is an absolute path referring to an existing directory, write output to files (one per process) underneath the given directory. Files will be named according to the final component of the trace2 SID, followed by a counter to avoid potential collisions. This makes it more convenient to collect traces for every git invocation by unconditionally setting the relevant trace2 envvar to a constant directory name.

2019-03-18parse-options: make OPT_ARGUMENT() more usefulLibravatar Johannes Schindelin1-1/+3
`OPT_ARGUMENT()` is intended to keep the specified long option in `argv` and not to do anything else. However, it would make a lot of sense for the caller to know whether this option was seen at all or not. For example, we want to teach `git difftool` to work outside of any Git worktree, but only when `--no-index` was specified. Note: nothing in Git uses OPT_ARGUMENT(). Even worse, looking through the commit history, one can easily see that nothing even ever used it, apart from the regression test. So not only do we make `OPT_ARGUMENT()` more useful, we are also about to introduce its first real user!

2019-01-22commit-graph: rename "large edges" to "extra edges"Libravatar SZEDER Gábor1-2/+2
The optional 'Large Edge List' chunk of the commit graph file stores parent information for commits with more than two parents, and the names of most of the macros, variables, struct fields, and functions related to this chunk contain the term "large edges", e.g. write_graph_chunk_large_edges(). However, it's not a really great term, as the edges to the second and subsequent parents stored in this chunk are not any larger than the edges to the first and second parents stored in the "main" 'Commit Data' chunk. It's the number of edges, IOW number of parents, that is larger compared to non-merge and "regular" two-parent merge commits. And indeed, two functions in 'commit-graph.c' have a local variable called 'num_extra_edges' that refer to the same thing, and this "extra edges" term is much better at describing these edges. So let's rename all these references to "large edges" in macro, variable, function, etc. names to "extra edges". There is a GRAPH_OCTOPUS_EDGES_NEEDED macro as well; for the sake of consistency rename it to GRAPH_EXTRA_EDGES_NEEDED. We can do so safely without causing any incompatibility issues, because the term "large edges" doesn't come up in the file format itself in any form (the chunk's magic is {'E', 'D', 'G', 'E'}, there is no 'L' in there), but only in the specification text. The string "large edges", however, does come up in the output of 'git commit-graph read' and in tests looking at its input, but that command is explicitly documented as debugging aid, so we can change its output and the affected tests safely.

2019-01-17{fetch,upload}-pack: sideband v2 fetch responseLibravatar Jonathan Tan1-0/+10
Currently, a response to a fetch request has sideband support only while the packfile is being sent, meaning that the server cannot send notices until the start of the packfile. Extend sideband support in protocol v2 fetch responses to the whole response. upload-pack will advertise it if the uploadpack.allowsidebandall configuration variable is set, and fetch-pack will automatically request it if advertised. If the sideband is to be used throughout the whole response, upload-pack will use it to send errors instead of prefixing a PKT-LINE payload with "ERR ". This will be tested in a subsequent patch.

2019-01-02pack-protocol.txt: accept error packets in any contextLibravatar Masaya Suzuki1-9/+11
In the Git pack protocol definition, an error packet may appear only in a certain context. However, servers can face a runtime error (e.g. I/O error) at an arbitrary timing. This patch changes the protocol to allow an error packet to be sent instead of any packet. Without this protocol spec change, when a server cannot process a request, there's no way to tell that to a client. Since the server cannot produce a valid response, it would be forced to cut a connection without telling why. With this protocol spec change, the server can be more gentle in this situation. An old client may see these error packets as an unexpected packet, but this is not worse than having an unexpected EOF. Following this protocol spec change, the error packet handling code is moved to pkt-line.c. Implementation wise, this implementation uses pkt-line to communicate with a subprocess. Since this is not a part of Git protocol, it's possible that a packet that is not supposed to be an error packet is mistakenly parsed as an error packet. This error packet handling is enabled only for the Git pack protocol parsing code considering this.

2018-11-06parse-options: drop OPT_DATE()Libravatar Jeff King1-4/+0
There are no users of OPT_DATE except for test-parse-options; its only caller went away in 27ec394a97 (prune: introduce OPT_EXPIRY_DATE() and use it, 2013-04-25). It also has a bug: it does not specify PARSE_OPT_NONEG, but its callback does not respect the "unset" flag, and will feed NULL to approxidate() and segfault. Probably this should be marked with NONEG, or the callback should set the timestamp to some sentinel value (e.g,. "0", or "(time_t)-1"). But since there are no callers, deleting it means we don't even have to think about what the right behavior should be.

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>
2018-10-11eoie: 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>
