It was easy to make mistakes in one-off standalone + programs (like test helpers). A common "main()" function that + calls cmd_main() of individual program has been introduced to + make it harder to make mistakes. + + * "git merge" with renormalization did not work well with + merge-recursive, due to "safer crlf" conversion kicking in when it + shouldn't. + + * The reflog output format is documented better, and a new format + --date=unix to report the seconds-since-epoch (without timezone) + has been added. + + * "git push --force-with-lease" already had enough logic to allow + ensuring that such a push results in creation of a ref (i.e. the + receiving end did not have another push from sideways that would be + discarded by our force-pushing), but didn't expose this possibility + to the users. It does so now. + + * "import-tars" fast-import script (in contrib/) used to ignore a + hardlink target and replaced it with an empty file, which has been + corrected to record the same blob as the other file the hardlink is + shared with. + + * "git mv dir non-existing-dir/" did not work in some environments + the same way as existing mainstream platforms. The code now moves + "dir" to "non-existing-dir", without relying on rename("A", "B/") + that strips the trailing slash of '/'. + + * The "t/" hierarchy is prone to get an unusual pathname; "make test" + has been taught to make sure they do not contain paths that cannot + be checked out on Windows (and the mechanism can be reusable to + catch pathnames that are not portable to other platforms as need + arises). + + * When "git merge-recursive" works on history with many criss-cross + merges in "verbose" mode, the names the command assigns to the + virtual merge bases could have overwritten each other by unintended + reuse of the same piece of memory. + + * "git checkout --detach <branch>" used to give the same advice + message as that is issued when "git checkout <tag>" (or anything + that is not a branch name) is given, but asking with "--detach" is + an explicit enough sign that the user knows what is going on. The + advice message has been squelched in this case. + + * "git difftool" by default ignores the error exit from the backend + commands it spawns, because often they signal that they found + differences by exiting with a non-zero status code just like "diff" + does; the exit status codes 126 and above however are special in + that they are used to signal that the command is not executable, + does not exist, or killed by a signal. "git difftool" has been + taught to notice these exit status codes. + + * On Windows, help.browser configuration variable used to be ignored, + which has been corrected. + + * The "git -c var[=val] cmd" facility to append a configuration + variable definition at the end of the search order was described in + git(1) manual page, but not in git-config(1), which was more likely + place for people to look for when they ask "can I make a one-shot + override, and if so how?" + + * The tempfile (hence its user lockfile) API lets the caller to open + a file descriptor to a temporary file, write into it and then + finalize it by first closing the filehandle and then either + removing or renaming the temporary file. When the process spawns a + subprocess after obtaining the file descriptor, and if the + subprocess has not exited when the attempt to remove or rename is + made, the last step fails on Windows, because the subprocess has + the file descriptor still open. Open tempfile with O_CLOEXEC flag + to avoid this (on Windows, this is mapped to O_NOINHERIT). + +Also contains minor documentation updates and code clean-ups. |
