test smart http fetch and push The top level directory "/smart/" of the test Apache server is mapped through our git-http-backend CGI, but uses the same underlying repository space as the server's document root. This is the most simple installation possible. Server logs are checked to verify the client has accessed only the smart URLs during the test. During fetch testing the headers are also logged from libcurl to ensure we are making a reasonably sane HTTP request, and getting back reasonably sane response headers from the CGI. When validating the request headers used during smart fetch we munge away the actual Content-Length and replace it with the placeholder "xxx". This avoids unnecessary varability in the test caused by an unrelated change in the requested capabilities in the first want line of the request. However, we still want to look for and verify that Content-Length was used, because smaller payloads should be using Content-Length and not "Transfer-Encoding: chunked". When validating the server response headers we must discard both Content-Length and Transfer-Encoding, as Apache2 can use either format to return our response. During development of this test I observed Apache returning both forms, depending on when the processes got CPU time. If our CGI returned the pack data quickly, Apache just buffered the whole thing and returned a Content-Length. If our CGI took just a bit too long to complete, Apache flushed its buffer and instead used "Transfer-Encoding: chunked". Signed-off-by: Shawn O.

GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=main
tests: mark tests relying on the current default for `init.defaultBranch` In addition to the manual adjustment to let the `linux-gcc` CI job run the test suite with `master` and then with `main`, this patch makes sure that GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME is set in all test scripts that currently rely on the initial branch name being `master by default. To determine which test scripts to mark up, the first step was to force-set the default branch name to `master` in - all test scripts that contain the keyword `master`, - t4211, which expects `t/t4211/history.export` with a hard-coded ref to initialize the default branch, - t5560 because it sources `t/t556x_common` which uses `master`, - t8002 and t8012 because both source `t/annotate-tests.sh` which also uses `master`) This trick was performed by this command: $ sed -i '/^ *\. \.\/\(test-lib\|lib-\(bash\|cvs\|git-svn\)\|gitweb-lib\)\.sh$/i\ GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=master\ export GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME\ ' $(git grep -l master t/t[0-9]*.sh) \ t/t4211*.sh t/t5560*.sh t/t8002*.sh t/t8012*.sh After that, careful, manual inspection revealed that some of the test scripts containing the needle `master` do not actually rely on a specific default branch name: either they mention `master` only in a comment, or they initialize that branch specificially, or they do not actually refer to the current default branch. Therefore, the aforementioned modification was undone in those test scripts thusly: $ git checkout HEAD -- \ t/t0027-auto-crlf.sh t/t0060-path-utils.sh \ t/t1011-read-tree-sparse-checkout.sh \ t/t1305-config-include.sh t/t1309-early-config.sh \ t/t1402-check-ref-format.sh t/t1450-fsck.sh \ t/t2024-checkout-dwim.sh \ t/t2106-update-index-assume-unchanged.sh \ t/t3040-subprojects-basic.sh t/t3301-notes.sh \ t/t3308-notes-merge.sh t/t3423-rebase-reword.sh \ t/t3436-rebase-more-options.sh \ t/t4015-diff-whitespace.sh t/t4257-am-interactive.sh \ t/t5323-pack-redundant.sh t/t5401-update-hooks.sh \ t/t5511-refspec.sh t/t5526-fetch-submodules.sh \ t/t5529-push-errors.sh t/t5530-upload-pack-error.sh \ t/t5548-push-porcelain.sh \ t/t5552-skipping-fetch-negotiator.sh \ t/t5572-pull-submodule.sh t/t5608-clone-2gb.sh \ t/t5614-clone-submodules-shallow.sh \ t/t7508-status.sh t/t7606-merge-custom.sh \ t/t9302-fast-import-unpack-limit.sh We excluded one set of test scripts in these commands, though: the range of `git p4` tests. The reason? `git p4` stores the (foreign) remote branch in the branch called `p4/master`, which is obviously not the default branch. Manual analysis revealed that only five of these tests actually require a specific default branch name to pass; They were modified thusly: $ sed -i '/^ *\. \.\/lib-git-p4\.sh$/i\ GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=master\ export GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME\ ' t/t980[0167]*.sh t/t9811*.sh Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>

http-push: ensure unforced pushes fail when data would be lost When we push using the DAV-based protocol, the client is the one that performs the ref updates and therefore makes the checks to see whether an unforced push should be allowed. We make this check by determining if either (a) we lack the object file for the old value of the ref or (b) the new value of the ref is not newer than the old value, and in either case, reject the push. However, the ref_newer function, which performs this latter check, has an odd behavior due to the reuse of certain object flags. Specifically, it will incorrectly return false in its first invocation and then correctly return true on a subsequent invocation. This occurs because the object flags used by http-push.c are the same as those used by commit-reach.c, which implements ref_newer, and one piece of code misinterprets the flags set by the other. Note that this does not occur in all cases. For example, if the example used in the tests is changed to use one repository instead of two and rewind the head to add a commit, the test passes and we correctly reject the push. However, the example provided does trigger this behavior, and the code has been broken in this way since at least Git 2.0.0. To solve this problem, let's move the two sets of object flags so that they don't overlap, since we're clearly using them at the same time. The new set should not conflict with other usage because other users are either builtin code (which is not compiled into git http-push) or upload-pack (which we similarly do not use here).
