* git_config_set: reuse empty sectionsJohannes Schindelin2018-04-092-2/+14
| | | | | | | | | | | | | | | | | | | | It can happen quite easily that the last setting in a config section is removed, and to avoid confusion when there are comments in the config about that section, we keep a lone section header, i.e. an empty section. Now that we use the `event_fn` callback, it is easy to add support for re-using empty sections, so let's do that. Note: t5512-ls-remote requires that this change is applied *after* the patch "git config --unset: remove empty sections (in the common case)": without that patch, there would be empty `transfer` and `uploadpack` sections ready for reuse, but in the *wrong* order (and sconsequently, t5512's "overrides work between mixed transfer/upload-pack hideRefs" would fail).

* git config --unset: remove empty sections (in the common case)Johannes Schindelin2018-04-092-4/+93
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The original reasoning for not removing section headers upon removal of the last entry went like this: the user could have added comments about the section, or about the entries therein, and if there were other comments there, we would not know whether we should remove them. In particular, a concocted example was presented that looked like this (and was added to t1300): # some generic comment on the configuration file itself # a comment specific to this "section" section. [section] # some intervening lines # that should also be dropped key = value # please be careful when you update the above variable The ideal thing for `git config --unset section.key` in this case would be to leave only the first line behind, because all the other comments are now obsolete. However, this is unfeasible, short of adding a complete Natural Language Processing module to Git, which seems not only a lot of work, but a totally unreasonable feature (for little benefit to most users). Now, the real kicker about this problem is: most users do not edit their config files at all! In their use case, the config looks like this instead: [section] key = value ... and it is totally obvious what should happen if the entry is removed: the entire section should vanish. Let's generalize this observation to this conservative strategy: if we are removing the last entry from a section, and there are no comments inside that section nor surrounding it, then remove the entire section. Otherwise behave as before: leave the now-empty section (including those comments, even ones about the now-deleted entry). We have to be extra careful to handle the case where more than one entry is removed: any subset of them might be the last entries of their respective sections (and if there are no comments in or around that section, the section should be removed, too).

* git_config_set: make use of the config parser's event streamJohannes Schindelin2018-04-091-89/+81
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the recent commit with the title "config: introduce an optional event stream while parsing", we introduced an optional callback to keep track of the config parser's events "comment", "white-space", "section header" and "entry". One motivation for this feature was to make use of it in the code that edits the config. And this commit makes it so. Note: this patch changes the meaning of the `seen` array that records whether we saw the config entry that is to be edited: previously, it contained the end offset of the found entry. Now, we introduce a new array `parsed` that keeps a record of *all* config parser events (with begin/end offsets), and the items in the `seen` array now point into the `parsed` array. There are two reasons why we do it this way: 1. To keep the implementation simple, the config parser's event stream reports the event only after the config callback was called, so we would not receive the begin offset otherwise. 2. In the following patches, we will re-use the `parsed` array to fix two long-standing bugs related to empty sections. Note that this also makes the code more robust with respect to finding the begin offset of the part(s) of the config file to be edited, as we no longer back-track to find the beginning of the line.

* git_config_set: do not use a state machineJohannes Schindelin2018-04-091-30/+29
| | | | | | | | | | | | | | | | | | | While a neat theoretical construct, state machines are hard to read. In this instance, it does not even make a whole lot of sense because we are more interested in flags, anyway: has the section been seen? Has the key been seen? Does the current section match the key we are looking for? Besides, the state `SECTION_SEEN` was named in a misleading way: it did not indicate that we saw the section matching the key we are looking for, but it instead indicated that we are *currently* in that section. Let's just replace the state machine logic by clear and obvious flags. This will also make it easier to review the upcoming patches to use the newly-introduced `event_fn` callback of the config parser.

* config_set_store: rename some fields for consistencyJohannes Schindelin2018-04-091-32/+31
| | | | | | | | | | | | | | | | | | | | The `seen` field is the actual length of the `offset` array, and the `offset_alloc` field records what was allocated (to avoid resizing wherever `seen` has to be incremented). Elsewhere, we use the convention `name` for the array, where `name` is descriptive enough to guess its purpose, `name_nr` for the actual length and `name_alloc` to record the maximum length without needing to resize. Let's make the names of the fields in question consistent with that convention. This will also help with the next steps where we will let the git_config_set() machinery use the config event stream that we just introduced.

| | | | | | | | | | | | | This extends our config parser so that it can optionally produce an event stream via callback function, where it reports e.g. when a comment was parsed, or a section header, etc. This parser will be used subsequently to handle the scenarios better where removing config entries would make sections empty, or where a new entry could be added to an already-existing, empty section.

* t1300: `--unset-all` can leave an empty section behind (bug)Johannes Schindelin2018-04-091-0/+11
| | | | | | | | | | | | We already have a test demonstrating that removing the last entry from a config section fails to remove the section header of the now-empty section.

| | | | | | | | | | | | | | | | In https://public-inbox.org/git/7vvc8alzat.fsf@alter.siamese.dyndns.org/ a reasonable patch was made quite a bit less so by changing a test case demonstrating a bug to a test case that demonstrates that we ask for too much: the test case 'unsetting the last key in a section removes header' now expects a future bug fix to be able to determine whether a free-form comment above a section header refers to said section or not. Rather than shooting for the stars (and not even getting off the ground), let's start shooting for something obtainable and be reasonably confident that we *can* get it.

| | | | | | | | | | | | | | | | | | | | | | | | | | Currently, we are slightly overzealous When removing an entry from a config file of this form: [abc]a [xyz] key = value When calling `git config --unset abc.a` on this file, it leaves this (invalid) config behind: [ [xyz] key = value The reason is that we try to search for the beginning of the line (or for the end of the preceding section header on the same line) that defines abc.a, but as an optimization, we subtract 2 from the offset pointing just after the definition before we call find_beginning_of_line(). That function, however, *also* performs that optimization and promptly fails to find the section header correctly.

Let's drop it in the name of simplicity. This is morally a revert of 3131b71301 (Add "--show-all" revision walker flag for debugging, 2008-02-09), but note that I did leave in the mapping of UNINTERESTING to "^" in get_revision_mark(). I don't think this would be possible to trigger with the current code, but it's the only sensible marker. We'll skip the usual deprecation period because this was explicitly a debugging aid that was never documented.

Some of these commits may be unparsed when we try to show them (since we may or may not need to walk their parents to fulfill the request). Commit 3131b71301 (Add "--show-all" revision walker flag for debugging, 2008-02-09) resolved this by just skipping pretty-printing for commits without their object contents cached, saying: Because we now end up listing commits we may not even have been parsed at all "show_log" and "show_commit" need to protect against commits that don't have a commit buffer entry. That was the easy fix to avoid the pretty-printer segfaulting, but: 1. It doesn't work for all formats. E.g., --oneline prints the oid for each such commit but not a trailing newline, leading to jumbled output. 2. It only affects some commits, depending on whether we happened to parse them or not (so if they were at the tip of an UNINTERESTING starting point, or if we happened to traverse over them, you'd see more data). 3. It unncessarily ties the decision to show the verbose header to whether the commit buffer was cached. That makes it harder to change the logic around caching (e.g., if we could traverse without actually loading the full commit objects). These days it's safe to feed such a commit to the pretty-print code. Since be5c9fb904 (logmsg_reencode: lazily load missing commit buffers, 2013-01-26), we'll load it on demand in such a case. So let's just always show the verbose headers. This does change the behavior of plumbing, but: a. The --show-all option was explicitly introduced as a debugging aid, and was never documented (and has rarely even been mentioned on the list by git devs). b. Avoiding the commits was already not deterministic due to (2) above. So the caller might have seen full headers for these commits anyway, and would need to be prepared for it.

(The check is for a 'large' byte count in a call to memcpy(), memset(), copy_from_user() and copy_to_user() functions). A recent release of sparse (v0.5.1) has introduced some options to allow this check to be turned off (-Wno-memcpy-max-count) or to specify the actual limit used (-fmemcpy-max-count=COUNT), rather than a hard-coded limit of 100000. In order to suppress the warning, add a target for pack-revindex.sp that adds the '-Wno-memcpy-max-count' option to the SPARSE_FLAGS variable.

This means that the '-isystem /usr/include/w32api' option to sparse is no longer necessary (to allow sparse to find the WIN32 header files). In addition, the '-Wno-one-bit-signed-bitfield' option can be removed, since the warning suppressed by that option was only provoked by a WIN32 header file.

While it might seem nonsensical at first glance to both poison and disable gettext, it's useful to be able to do a poison test-run on a system that doesn't have gettext at all. And it works fine for C programs; the problem is only with the shell code. The issue is that we check the baked-in USE_GETTEXT_SCHEME value before GETTEXT_POISON. And when NO_GETTEXT is set, the Makefile sets USE_GETTEXT_SCHEME to "fallthrough". So one fix would be to have the Makefile just set USE_GETTEXT_SCHEME to "poison" if GETTEXT_POISON is set. But there are two problems with that: 1. USE_GETTEXT_SCHEME is actually a user-facing knob, so conceivably somebody could override it with: make USE_GETTEXT_SCHEME=gnu GETTEXT_POISON=1 which would do the wrong thing (though that's much less likely than them having the variable set in their config.mak and just overriding GETTEXT_POISON on the command-line for a one-off test). 2. We don't actually bake GETTEXT_POISON in to the shell library like we do for the C code. It checks $GIT_GETTEXT_POISON at runtime, which is set up by the test suite. So it makes sense to put the fix in the runtime code, too, which would cover something like: GIT_GETTEXT_POISON=foo git foo It's not likely that people use the poison code outside of running the test suite, but it's easy enough to make this case work.

Just checking the latter covers both cases. I suspect the original was trying to give better output when the test fails, but using "-x" covers that these days.

All the details are still hidden away behind the `fnmatch(3)` wall because bringing the whole specification here may be too much.
