Merge branch 'bw/remote-curl-compressed-responses'

2018-05-30T12:51:29Z

Our HTTP client code used to advertise that we accept gzip encoding from the other side; instead, just let cURL library to advertise and negotiate the best one. * bw/remote-curl-compressed-responses: remote-curl: accept compressed responses with protocol v2 remote-curl: accept all encodings supported by curl

Merge branch 'jk/snprintf-truncation'

2018-05-30T12:51:28Z

Avoid unchecked snprintf() to make future code auditing easier. * jk/snprintf-truncation: fmt_with_err: add a comment that truncation is OK shorten_unambiguous_ref: use xsnprintf fsmonitor: use internal argv_array of struct child_process log_write_email_headers: use strbufs http: use strbufs instead of fixed buffers

Merge branch 'bc/object-id'

2018-05-30T05:04:10Z

Conversion from uchar[20] to struct object_id continues. * bc/object-id: (42 commits) merge-one-file: compute empty blob object ID add--interactive: compute the empty tree value Update shell scripts to compute empty tree object ID sha1_file: only expose empty object constants through git_hash_algo dir: use the_hash_algo for empty blob object ID sequencer: use the_hash_algo for empty tree object ID cache-tree: use is_empty_tree_oid sha1_file: convert cached object code to struct object_id builtin/reset: convert use of EMPTY_TREE_SHA1_BIN builtin/receive-pack: convert one use of EMPTY_TREE_SHA1_HEX wt-status: convert two uses of EMPTY_TREE_SHA1_HEX submodule: convert several uses of EMPTY_TREE_SHA1_HEX sequencer: convert one use of EMPTY_TREE_SHA1_HEX merge: convert empty tree constant to the_hash_algo builtin/merge: switch tree functions to use object_id builtin/am: convert uses of EMPTY_TREE_SHA1_BIN to the_hash_algo sha1-file: add functions for hex empty tree and blob OIDs builtin/receive-pack: avoid hard-coded constants for push certs diff: specify abbreviation size in terms of the_hash_algo upload-pack: replace use of several hard-coded constants ...

Merge branch 'js/use-bug-macro'

2018-05-30T05:04:07Z

Developer support update, by using BUG() macro instead of die() to mark codepaths that should not happen more clearly. * js/use-bug-macro: BUG_exit_code: fix sparse "symbol not declared" warning Convert remaining die*(BUG) messages Replace all die("BUG: ...") calls by BUG() ones run-command: use BUG() to report bugs, not die() test-tool: help verifying BUG() code paths

remote-curl: accept all encodings supported by curl

2018-05-23T01:24:12Z

Configure curl to accept all encodings which curl supports instead of only accepting gzip responses. This fixes an issue when using an installation of curl which is built without the "zlib" feature. Since aa90b9697 (Enable info/refs gzip decompression in HTTP client, 2012-09-19) we end up requesting "gzip" encoding anyway despite libcurl not being able to decode it. Worse, instead of getting a clear error message indicating so, we end up falling back to "dumb" http, producing a confusing and difficult to debug result. Since curl doesn't do any checking to verify that it supports the a requested encoding, instead set the curl option `CURLOPT_ENCODING` with an empty string indicating that curl should send an "Accept-Encoding" header containing only the encodings supported by curl.

http: use strbufs instead of fixed buffers

2018-05-21T00:54:30Z

We keep the names of incoming packs and objects in fixed PATH_MAX-size buffers, and snprintf() into them. This is unlikely to end up with truncated filenames, but it is possible (especially on systems where PATH_MAX is shorter than actual paths can be). Let's switch to using strbufs, which makes the question go away entirely. Signed-off-by: Jeff King Signed-off-by: Junio C Hamano

Merge branch 'bw/protocol-v2'

2018-05-08T06:59:16Z

The beginning of the next-gen transfer protocol. * bw/protocol-v2: (35 commits) remote-curl: don't request v2 when pushing remote-curl: implement stateless-connect command http: eliminate "# service" line when using protocol v2 http: don't always add Git-Protocol header http: allow providing extra headers for http requests remote-curl: store the protocol version the server responded with remote-curl: create copy of the service name pkt-line: add packet_buf_write_len function transport-helper: introduce stateless-connect transport-helper: refactor process_connect_service transport-helper: remove name parameter connect: don't request v2 when pushing connect: refactor git_connect to only get the protocol version once fetch-pack: support shallow requests fetch-pack: perform a fetch using v2 upload-pack: introduce fetch server command push: pass ref prefixes when pushing fetch: pass ref prefixes when fetching ls-remote: pass ref prefixes when requesting a remote's refs transport: convert transport_get_remote_refs to take a list of ref prefixes ...

Replace all die("BUG: ...") calls by BUG() ones

2018-05-06T10:06:13Z

In d8193743e08 (usage.c: add BUG() function, 2017-05-12), a new macro was introduced to use for reporting bugs instead of die(). It was then subsequently used to convert one single caller in 588a538ae55 (setup_git_env: convert die("BUG") to BUG(), 2017-05-12). The cover letter of the patch series containing this patch (cf 20170513032414.mfrwabt4hovujde2@sigill.intra.peff.net) is not terribly clear why only one call site was converted, or what the plan is for other, similar calls to die() to report bugs. Let's just convert all remaining ones in one fell swoop. This trick was performed by this invocation: sed -i 's/die("BUG: /BUG("/g' $(git grep -l 'die("BUG' \*.c) Signed-off-by: Johannes Schindelin Signed-off-by: Junio C Hamano

Merge branch 'lv/tls-1.3'

2018-04-11T04:09:57Z
