2007-09-10git-tag -s must fail if gpg cannot sign the tag.Carlos Rica
Most of this patch code and message was written by Shawn O. Pearce. I made some tests to know what the problem was, and then I changed the code related with the SIGPIPE signal. If the user has misconfigured `user.signingkey` in their .git/config or just doesn't have any secret keys on their keyring and they ask for a signed tag with `git tag -s` we better make sure the resulting tag was actually signed by gpg. Prior versions of builtin git-tag allowed this failure to slip by without error as they were not checking the return value of the finish_command() so they did not notice when gpg exited with an error exit status. They also did not fail if gpg produced an empty output or if read_in_full received an error from the read system call while trying to read the pipe back from gpg. Finally, we did not actually honor any return value from the do_sign function as it returns ssize_t but was being stored into an unsigned long. This caused the compiler to optimize out the die condition, allowing git-tag to continue along and create the tag object. However, when gpg gets a wrong username, it exits before any read was done and then the writing process receives SIGPIPE and program is terminated. By ignoring this signal, anyway, the function write_or_die gets EPIPE from write_in_full and exits returning 0 to the system without a message. Here we better call to write_in_full directly so we can fail printing a message and return safely to the caller. With these issues fixed `git-tag -s` will now fail to create the tag and will report a non-zero exit status to its caller, thereby allowing automated helper scripts to detect (and recover from) failure if gpg is not working properly.

2007-09-01git-tag: Fix -l option to use better shell style globs.Carlos Rica
This patch removes certain behaviour of "git tag -l foo", currently listing every tag name having "foo" as a substring. The same thing now could be achieved doing "git tag -l '*foo*'". This feature was added recently when got the -n option for showing tag annotations, because that commit also replaced the old "grep pattern" behaviour with a more preferable "shell pattern" behaviour (although slightly modified as you can see). Thus, the following builtin-tag.c implemented it in order to ensure that tests were passing unchanged with both programs. Since common "shell patterns" match names with a given substring _only_ when * is inserted before and after (as in "*substring*"), and the "plain" behaviour cannot be achieved easily with the current implementation, this is mostly the right thing to do, in order to make it more flexible and consistent. Tests for "git tag" were also changed to reflect this. Signed-off-by: Carlos Rica <> Signed-off-by: Junio C Hamano <>
2007-07-21builtin-tag.c: Fix two memory leaks and minor notation changes.Carlos Rica
A repeated call to read_sha1_file was not freing memory when the buffer was allocated but returned size was zero. Also, now the program does not allow many -F or -m options, which was a bug too because it was not freing the memory allocated for any previous -F or -m options. Tests are provided for ensuring that only one option -F or -m is given. Also, another test is shipped here, to check that "git tag" fails when a non-existing file is passed to the -F option, something that allowed creating the tag with an empty message.

2007-07-21launch_editor(): Heed GIT_EDITOR and core.editor settingsJohannes Schindelin
In the commit 'Add GIT_EDITOR environment and core.editor configuration variables', this was done for the shell scripts. Port it over to builtin-tag's version of launch_editor(), which is just about to be refactored into editor.c. Signed-off-by: Johannes Schindelin <> Signed-off-by: Junio C Hamano <>
2007-07-20Make git tag a builtin.Carlos Rica
This replaces the script "" with "builtin-tag.c". The existing test suite for "git tag" guarantees the compatibility with the features provided by the script version. There are some minor changes in the behaviour of "git tag" here: "git tag -v" now can get more than one tag to verify, like "git tag -d" does, "git tag" with no arguments prints all tags, more like "git branch" does, and "git tag -n" also prints all tags with annotations (without needing -l). Tests and documentation were also updated to reflect these changes. The program is currently calling the script "git verify-tag" for verify. This can be changed porting it to C and calling its functions directly from builtin-tag.c. Signed-off-by: Carlos Rica <> Signed-off-by: Junio C Hamano <>
