* parse_mailboxes: accept extra text after <...> addressMatthieu Moy2016-10-141-0/+29
| | | | | | | | | | | | | | | | | | | The test introduced in this commit succeeds without the patch to Git.pm if Mail::Address is installed, but fails otherwise because our in-house parser does not accept any text after the email address. They succeed both with and without Mail::Address after this commit. Mail::Address accepts extra text and considers it as part of the name, iff the address is surrounded with <...>. The implementation mimics this behavior as closely as possible. This mostly restores the behavior we had before b1c8a11 (send-email: allow multiple emails using --cc, --to and --bcc, 2015-06-30), but we keep the possibility to handle comma-separated lists.

* send-email: suppress meaningless whitespaces in from fieldrl/send-email-aliasesRemi Lespinet2015-07-071-0/+24
| | | | | | | | | | | | | | | | | | | Remove leading and trailing whitespaces in from field before interepreting it to improve consistency with other options. The split_addrs function already take care of trailing and leading whitespaces for to, cc and bcc fields. The from option now: - has the same behavior when passing arguments like " jdoe@example.com ", "\t jdoe@example.com " or "jdoe@example.com". - interprets aliases in string containing leading and trailing whitespaces such as " alias" or "alias\t" like other options.

* send-email: allow multiple emails using --cc, --to and --bccRemi Lespinet2015-07-071-0/+44
| | | | | | | | | | | | | | | | | | | | | | | | Accept a list of emails separated by commas in flags --cc, --to and --bcc. Multiple addresses can already be given by using these options multiple times, but it is more convenient to allow cutting-and-pasting a list of addresses from the header of an existing e-mail message, which already lists them as comma-separated list, as a value to a single parameter. The following format can now be used: $ git send-email --to='Jane <jdoe@example.com>, mike@example.com' Remove the limitation imposed by 79ee555b (Check and document the options to prevent mistakes, 2006-06-21) which rejected every argument with comma in --cc, --to and --bcc.

* send-email: reduce dependencies impact on parse_address_lineRemi Lespinet2015-07-072-0/+94
| | | | | | | | | | | | | | | | | | | | | | | | | | | parse_address_line had not the same behavior whether the user had Mail::Address or not. Teach parse_address_line to behave like Mail::Address. When the user input is correct, this implementation behaves exactly like Mail::Address except when there are quotes inside the name: "Jane Do"e <jdoe@example.com> In this case the result of parse_address_line is: With M::A : "Jane Do" e <jdoe@example.com> Without : "Jane Do e" <jdoe@example.com> When the user input is not correct, the behavior is also mostly the same. Unlike Mail::Address, this doesn't parse groups and recursive commentaries.

|\ | | | | | | | | | | | | | | | | | | | | | | | | Unlike "$EDITOR" and "$GIT_EDITOR" that can hold the path to the command and initial options (e.g. "/path/to/emacs -nw"), 'git p4' did not let the shell interpolate the contents of the environment variable that name the editor "$P4EDITOR" (and "$EDITOR", too).

There isn't a shorthand for the latter, but it's useful to have. For instance, you may want to know which commits you haven't pushed yet: git log @{push}.. Or as a more complicated example, imagine that you normally pull changes from origin/master (which you set as your @{upstream}), and push changes to your own personal fork (e.g., as myfork/topic). You may push to your fork from multiple machines, requiring you to integrate the changes from the push destination, rather than upstream. With this patch, you can just do: git rebase @{push} rather than typing out the full name. The heavy lifting is all done by branch_get_push; here we just wire it up to the "@{push}" syntax.

Let's teach the helper to optionally report these specific errors. This lets us convert another callsite, and means we can use the helper in other locations that want to give the same error messages. The logic and error messages come straight from sha1_name.c, with the exception that we start each error with a lowercase letter, as is our usual style (note that a few tests need updated as a result).

In such cases, 'git rebase' leaves the sha1 of the commit being rewritten in "$state_dir"/stopped-sha, and subsequent 'git rebase --continue' will call the post-rewrite hook with this sha1 as <old-sha1> argument to the post-rewrite hook. The case of 'git rebase' stopping because of a failed 'exec' command is different: it gives the opportunity to the user to examine or fix the failure, but does not stop saying "here's a commit to edit, use --continue when you're done". So, there's no reason to call the post-rewrite hook for 'exec' commands. If the user did rewrite the commit, it would be with 'git commit --amend' which already called the post-rewrite hook. Fix the behavior to leave no stopped-sha file in case of failed exec command, and teach 'git rebase --continue' to skip record_in_rewritten if no stopped-sha file is found.

Only objects reachable from the branch tips, i.e. the union of advertised branches and branches hidden by transfer.hideRefs, will be processed. Note that there is an associated cost of having to walk back the history to check the reachability. This feature can be used when obtaining the content of a certain commit, for which the sha1 is known, without the need of cloning the whole repository, especially if a shallow fetch is used. Useful cases are e.g. repositories containing large files in the history, fetching only the needed data for a submodule checkout, when sharing a sha1 without telling which exact branch it belongs to and in Gerrit, if you think in terms of commits instead of change numbers. (The Gerrit case has already been solved through allowTipSHA1InWant as every Gerrit change has a ref.)

Rather than annotate each command to reject a non-empty $FLAGS variable, we can notice that "stash show" is the only command that actually _wants_ arbitrary flags.

This traces back to these lines in sha1_file.c:index_core: if (!size) { ret = index_mem(sha1, NULL, size, type, path, flags); The problem here is that content to be added to the index can be supplied from an fd, or from a memory buffer, or from a pathname. This call is supplying a NULL buffer pointer and a zero size. Downstream logic takes the complete absence of a buffer to mean the data is to be found elsewhere -- for instance, these, from convert.c: if (params->src) { write_err = (write_in_full(child_process.in, params->src, params->size) < 0); } else { write_err = copy_fd(params->fd, child_process.in); } ~If there's a buffer, write from that, otherwise the data must be coming from an open fd.~ Perfectly reasonable logic in a routine that's going to write from either a buffer or an fd. So change `index_core` to supply an empty buffer when indexing an empty file. There's a patch out there that instead changes the logic quoted above to take a `-1` fd to mean "use the buffer", but it seems to me that the distinction between a missing buffer and an empty one carries intrinsic semantics, where the logic change is adapting the code to handle incorrect arguments.

In theory, git can go full-duplex; the client can consume our response while it is still sending the request. In practice, however, HTTP is a half-duplex protocol. Even if our client is ready to read and write simultaneously, we may have other HTTP infrastructure in the way, including the webserver that spawns our CGI, or any intermediate proxies. In at least one documented case[1], this leads to deadlock when trying a fetch over http. What happens is basically: 1. Apache proxies the request to the CGI, http-backend. 2. http-backend gzip-inflates the data and sends the result to upload-pack. 3. upload-pack acts on the data and generates output over the pipe back to Apache. Apache isn't reading because it's busy writing (step 1). This works fine most of the time, because the upload-pack output ends up in a system pipe buffer, and Apache reads it as soon as it finishes writing. But if both the request and the response exceed the system pipe buffer size, then we deadlock (Apache blocks writing to http-backend, http-backend blocks writing to upload-pack, and upload-pack blocks writing to Apache). We need to break the deadlock by spooling either the input or the output. In this case, it's ideal to spool the input, because Apache does not start reading either stdout _or_ stderr until we have consumed all of the input. So until we do so, we cannot even get an error message out to the client. The solution is fairly straight-forward: we read the request body into an in-memory buffer in http-backend, freeing up Apache, and then feed the data ourselves to upload-pack. But there are a few important things to note: 1. We limit the in-memory buffer to prevent an obvious denial-of-service attack. This is a new hard limit on requests, but it's unlikely to come into play. The default value is 10MB, which covers even the ridiculous 100,000-ref negotation in the included test (that actually caps out just over 5MB). But it's configurable on the off chance that you don't mind spending some extra memory to make even ridiculous requests work. 2. We must take care only to buffer when we have to. For pushes, the incoming packfile may be of arbitrary size, and we should connect the input directly to receive-pack. There's no deadlock problem here, though, because we do not produce any output until the whole packfile has been read. For upload-pack's initial ref advertisement, we similarly do not need to buffer. Even though we may generate a lot of output, there is no request body at all (i.e., it is a GET, not a POST).

However, if pull.ff=true, no switch is passed to git-merge. This leads to the confusing behavior where pull.ff=false or pull.ff=only is able to override merge.ff, while pull.ff=true is unable to.

But the version of Git back then didn't behave well, without (doubly) being told that it is inside a bare repository by exporting "GIT_DIR=.". The form of the test we originally wanted to have was left commented out as a reminder. Nowadays the test as originally intended works, so add it to the test suite.

This is not such a limitation for loose reference files. First, they don't take long to rewrite. Second, most reference updates have a known "old" value, so if another process is updating a reference at the same moment that we are trying to lock it, then probably the expected "old" value will not longer be valid, and the update will fail anyway. But these arguments do not hold for packed-refs: * The packed-refs file can be large and take significant time to rewrite. * Many references are stored in a single packed-refs file, so it could be that the other process was changing a different reference than the one that we are interested in. Therefore, it is much more likely for there to be spurious lock conflicts in connection to the packed-refs file, resulting in unnecessary command failures. So, if the first attempt to lock the packed-refs file fails, continue retrying for a configurable length of time before giving up. The default timeout is 1 second.
