2020-06-23http-push: ensure unforced pushes fail when data would be lostLibravatar brian m. carlson1-0/+16
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).

2020-01-15t5540: make hash size independentLibravatar brian m. carlson1-4/+2
Use regex values based on $OID_REGEX instead of hard-coding them based on expected object ID lengths. Signed-off-by: brian m. carlson <sandals@crustytoothpaste.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2019-03-14tests: use 'test_atexit' to stop httpdLibravatar SZEDER Gábor1-2/+0
Use 'test_atexit' to run cleanup commands to stop httpd at the end of the test script or upon interrupt or failure, as it is shorter, simpler, and more robust than registering such cleanup commands in the trap on EXIT in the test scripts.

2015-03-20t: fix severe &&-chain breakageLibravatar Jeff King1-1/+1
These are tests which are missing a link in their &&-chain, in a location which causes a significant portion of the test to be missed (e.g., the test effectively does nothing, or consists of a long string of actions and output comparisons, and we throw away the exit code of at least one part of the string).
