The code has been restructured. * js/early-config: setup.c: mention unresolved problems t1309: document cases where we would want early config not to die() setup_git_directory_gently_1(): avoid die()ing t1309: test read_early_config() read_early_config(): really discover .git/ read_early_config(): avoid .git/config hack when unneeded setup: make read_early_config() reusable setup: introduce the discover_git_directory() function setup_git_directory_1(): avoid changing global state setup: prepare setup_discovered_git_dir() for the root directory setup_git_directory(): use is_dir_sep() helper t7006: replace dubious test --- diff --git a/.gitignore b/.gitignore index b1020b875f..833ef3b0b7 100644 --- a/.gitignore +++ b/.gitignore @@ -114,6 +114,7 @@ /git-read-tree /git-rebase /git-rebase--am +/git-rebase--helper /git-rebase--interactive /git-rebase--merge /git-receive-pack diff --git a/.mailmap b/.mailmap index ab59b2fac6..e06526a493 100644 --- a/.mailmap +++ b/.mailmap @@ -177,6 +177,7 @@ Paolo Bonzini Pascal Obry Pascal Obry Pat Notz +Patrick Steinhardt Paul Mackerras Paul Mackerras Peter Baumann diff --git a/.travis.yml b/.travis.yml index 9c63c8c3f6..591cc57b80 100644 --- a/.travis.yml +++ b/.travis.yml @@ -39,6 +39,27 @@ env: matrix: include: + - env: Linux32 + os: linux + services: + - docker + before_install: + - docker pull daald/ubuntu32:xenial + before_script: + script: + - > + docker run + --interactive + --env DEFAULT_TEST_TARGET + --env GIT_PROVE_OPTS + --env GIT_TEST_OPTS + --env GIT_TEST_CLONE_2GB + --volume "${PWD}:/usr/src/git" + daald/ubuntu32:xenial + /usr/src/git/ci/run-linux32-build.sh $(id -u $USER) + # Use the following command to debug the docker build locally: + # $ docker run -itv "${PWD}:/usr/src/git" --entrypoint /bin/bash daald/ubuntu32:xenial + # root@container:/# /usr/src/git/ci/run-linux32-build.sh - env: Documentation os: linux compiler: clang diff --git a/Documentation/RelNotes/2.12.1.txt b/Documentation/RelNotes/2.12.1.txt new file mode 100644 index 0000000000..a74f7db747 --- /dev/null +++ b/Documentation/RelNotes/2.12.1.txt @@ -0,0 +1,41 @@ +Git v2.12.1 Release Notes +========================= + +Fixes since v2.12 +----------------- + + * Reduce authentication round-trip over HTTP when the server supports + just a single authentication method.

Each script is +similar to the normal test scripts found in t/, but with the added twist +that two special versions of git, "git.a" and "git.b", are available in +the PATH. Individual tests can then check the interaction between the +two versions. + +When you add a feature that handles backwards compatibility between git +versions, it's encouraged to add a test here to make sure it behaves as +you expect. + + +Running Tests +------------- + +The easiest way to run tests is to say "make". This runs all +the tests against their default versions. + +You can run a single test like: + + $ ./i0000-basic.sh + ok 1 - bare git is forbidden + ok 2 - git.a version (v1.6.6.3) + ok 3 - git.b version (v2.11.1) + # passed all 3 test(s) + 1..3 + +Each test contains default versions to run against. You may override +these by setting `GIT_TEST_VERSION_A` and `GIT_TEST_VERSION_B` in the +environment. Note that not all combinations will give sensible outcomes +for all tests (e.g., a test checking for a specific old/new interaction +may want something "old" enough" and something "new" enough; see +individual tests for details). + +Version names should be resolvable as revisions in the current +repository. They will be exported and built as needed using the +config.mak files found at the root of your working tree. + +The exception is the special version "." which uses the currently-built +contents of your working tree. + +You can set the following variables (in the environment or in your config.mak): + + GIT_INTEROP_MAKE_OPTS + Options to pass to `make` when building a git version (e.g., + `-j8`). + +You can also pass any command-line options taken by ordinary git tests (e.g., +"-v"). + + +Naming Tests +------------ + +The interop test files are named like: + + iNNNN-short-description.sh + +where N is a decimal digit. The same conventions for choosing NNNN as +for normal tests apply. + + +Writing Tests +------------- + +An interop test script starts like a normal script, declaring a few +variables and then including interop-lib.sh (which includes test-lib.sh). +Besides test_description, you should also set the $VERSION_A and $VERSION_B +variables to give the default versions to test against. See t0000-basic.sh for +an example. + +You can then use test_expect_success as usual, with a few differences: + + 1. The special commands "git.a" and "git.b" correspond to the + two versions. + + 2. You cannot call a bare "git". This is to prevent accidents where + you meant "git.a" or "git.b". + + 3. The trash directory is _not_ a git repository by default. You + should create one with the appropriate version of git. + +At the end of the script, call test_done as usual. diff --git a/t/interop/i0000-basic.sh b/t/interop/i0000-basic.sh new file mode 100755 index 0000000000..903e9193f8 --- /dev/null +++ b/t/interop/i0000-basic.sh @@ -0,0 +1,27 @@ +#!/bin/sh + +# Note that this test only works on real version numbers, +# as it depends on matching the output to "git version". +VERSION_A=v1.6.6.3 +VERSION_B=v2.11.1 + +test_description='sanity test interop library' +. ./interop-lib.sh + +test_expect_success 'bare git is forbidden' ' + test_must_fail git version +' + +test_expect_success "git.a version ($VERSION_A)" ' + echo git version ${VERSION_A#v} >expect && + git.a version >actual && + test_cmp expect actual +' + +test_expect_success "git.b version ($VERSION_B)" ' + echo git version ${VERSION_B#v} >expect && + git.b version >actual && + test_cmp expect actual +' + +test_done diff --git a/t/interop/i5500-git-daemon.sh b/t/interop/i5500-git-daemon.sh new file mode 100755 index 0000000000..1daf69420b --- /dev/null +++ b/t/interop/i5500-git-daemon.sh @@ -0,0 +1,41 @@ +#!/bin/sh + +VERSION_A=. +VERSION_B=v1.0.0 + +: ${LIB_GIT_DAEMON_PORT:=5500} +LIB_GIT_DAEMON_COMMAND='git.a daemon' + +test_description='clone and fetch by older client' +. ./interop-lib.sh +.

Let's consider some file in the root tree +# which is updated in each commit. +# +# When generating push number X, we feed commit X-1 (and +# thus blob X-1) as a preferred base. The resulting pack has +# blob X as a thin delta against blob X-1. +# +# On the receiving end, "index-pack --fix-thin" will +# complete the pack with a base copy of blob X-1. +# +# 3. In older versions of git, if we used the delta from +# pack X, then we'd always find blob X-1 as a base in the +# same pack (and generate a fresh delta). +# +# But with the pack mru, we jump from delta to delta +# following the traversal order: +# +# a. We grab blob X from pack X as a delta, putting it at +# the tip of our mru list. +# +# b. Eventually we move onto commit X-1. We need other +# objects which are only in pack X-1 (in the test code +# below, it's the containing tree). That puts pack X-1 +# at the tip of our mru list. +# +# c. Eventually we look for blob X-1, and we find the +# version in pack X-1 (because it's the mru tip). +# +# Now we have blob X as a delta against X-1, which is a delta +# against X-2, and so forth. +# +# In the real world, these small pushes would get exploded by +# unpack-objects rather than "index-pack --fix-thin", but the +# same principle applies to larger pushes (they only need one +# repeatedly-modified file to generate the delta chain). + +test_expect_success 'create series of packs' ' + test-genrandom foo 4096 >content && + prev= && + for i in $(test_seq 1 10) + do + cat content >file && + echo $i >>file && + git add file && + git commit -m $i && + cur=$(git rev-parse HEAD^{tree}) && + { + test -n "$prev" && echo "-$prev" + echo $cur + echo "$(git rev-parse :file) file" + } | git pack-objects --stdout >tmp && + git index-pack --stdin --fix-thin output && + perl -lne ' + /chain length = (\d+)/ and $len = $1; + END { print $len } + ' output +} + +# Note that this whole setup is pretty reliant on the current +# packing heuristics.
