2007-09-17send-email: make message-id generation a bit more robustLibravatar Junio C Hamano1-4/+11
Earlier code took Unix time and appended a few random digits. If you are firing off many messages within a second, you could issue the same id to different messages, which is a no-no. If you send out 31 messages within a single second, with random integer taken out of rand(4200), you have about 10% chance of producing the same message ID. This fixes the problem by uses a prefix string which is constant-per-invocation (time and pid), with a serial number for each message generated by the process appended at the end.

2007-09-17git-apply: fix whitespace strippingLibravatar J. Bruce Fields1-3/+10
The algorithm isn't right here: it accumulates any set of 8 spaces into tabs even if they're separated by tabs, so <four spaces><tab><four spaces><tab> is converted to <tab><tab><tab> when it should be just <tab><tab> So teach git-apply that a tab hides any group of less than 8 previous spaces in a row.

2007-09-16git-gui: Disable native platform text selection in "lists"Libravatar Shawn O. Pearce3-9/+18
Sometimes we use a Tk text widget as though it were a listbox. This happens typically when we want to show an icon to the left of the text label or just when a text widget is generally a better choice then the native listbox widget. In these cases if we want the user to have control over the selection we implement our own "in_sel" tag that shows the selected region and we perform our own selection management in the background via keybindings and mouse bindings. In such uses we don't want the user to be able to activate the native platform selection by dragging their mouse through the text widget. Doing so creates a very confusing display and the user is left wondering what it may mean to have two different types of selection in the same widget. Tk doesn't allow us to delete the "sel" tag that it uses internally to manage the native selection but it will allow us to make it invisible by setting the tag to have the same display properties as unselected text. So long as we don't actually use the "sel" tag for anything in code its effectively invisible. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
2007-09-16apply --index-info: fall back to current index for mode changesLibravatar Johannes Schindelin2-2/+39
"git diff" does not record index lines for pure mode changes (i.e. no lines changed). Therefore, apply --index-info would call out a bogus error. Instead, fall back to reading the info from the current index. Incidentally, this fixes an error where git-rebase would not rebase a commit including a pure mode change, and changes requiring a threeway merge. Noticed and later tested by Chris Shoemaker.

2007-09-15documentation: replace Discussion section by link to user-manual chapterLibravatar J. Bruce Fields3-597/+54
The "Discussion" section has a lot of useful information, but is a little wordy, especially for an already-long man page, and is designed for an audience more of potential git hackers than users, which probably doesn't make as much sense as git matures. Also, I (perhaps foolishly) forked a version in the user manual, which has been significantly rewritten in an attempt to address some of the above problems. So, remove this section and replace it by a (very terse) summary of the original material--my attempt at the World's Shortest Git Overview--and a reference to the appropriate chapter of the user manual. It's unfortunate to remove something that's been in this place for a long time, as some people may still depend on finding it there. But I think we'll want to do this some day anyway.

2007-09-15user-manual: adjust section levels in "git internals"Libravatar J. Bruce Fields1-5/+12
The descriptions of the various object types should all be a subsection of the "Object Database" section. I cribbed most of this chapter from the README (now core-intro.txt and git(7)), because there's stuff in there people need to know and I was too lazy to rewrite it. The audience isn't quite right, though--the chapter is a mixture of user- and developer- level documentation that isn't as appropriate now as it was originally. So, reserve this chapter for stuff users need to know, and move the source code introduction into a new "git hacking" chapter where we'll also move any hacker-only technical details.

2007-09-15revision walker: --cherry-pick is a limited operationLibravatar Johannes Schindelin2-0/+15
We used to rely on the fact that cherry-pick would trigger the code path to set limited = 1 in handle_commit(), when an uninteresting commit was encountered. However, when cherry picking between two independent branches, i.e. when there are no merge bases, and there is only linear development (which can happen when you cvsimport a fork of a project), no uninteresting commit will be encountered. So set limited = 1 when --cherry-pick was asked for. Noticed by Martin Bähr. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2007-09-14Fix the rename detection limit checkingLibravatar Linus Torvalds3-3/+19
This adds more proper rename detection limits. Instead of just checking the limit against the number of potential rename destinations, we verify that the rename matrix (which is what really matters) doesn't grow ridiculously large, and we also make sure that we don't overflow when doing the matrix size calculation. This also changes the default limits from unlimited, to a rename matrix that is limited to 100 entries on a side. You can raise it with the config entry, or by using the "-l<n>" command line flag, but at least the default is now a sane number that avoids spending lots of time (and memory) in situations that likely don't merit it. The choice of default value is of course very debatable. Limiting the rename matrix to a 100x100 size will mean that even if you have just one obvious rename, but you also create (or delete) 10,000 files, the rename matrix will be so big that we disable the heuristics. Sounds reasonable to me, but let's see if people hit this (and, perhaps more importantly, actually *care*) in real life.

2007-09-13git-gui: Provide 'uninstall' Makefile target to undo an installationLibravatar Shawn O. Pearce1-1/+27
Several users have requested a "make uninstall" target be provided in the stock git-gui Makefile so that they can undo an install if git-gui goes to the wrong place during the initial install, or if they are unhappy with the tool and want to remove it from their system. We currently assume that the complete set of files we need to delete are those defined by our Makefile and current source directory. This could differ from what the user actually has installed if they installed one version then attempt to use another to perform the uninstall. Right now I'm just going to say that is "pilot error". Users should uninstall git-gui using the same version of source that they used to make the installation. Perhaps in the future we could read tclIndex and base our uninstall decisions on its contents.

2007-09-13git-gui: Font chooser to handle a large number of font familiesLibravatar Shawn O. Pearce2-11/+182
Simon Sasburg noticed that on X11 if there are more fonts than can fit in the height of the screen Tk's native tk_optionMenu does not offer scroll arrows to the user and it is not possible to review all choices or to select those that are off-screen. On Mac OS X the tk_optionMenu works properly but is awkward to navigate if the list is long. This is a rewrite of our font selection by providing a new modal dialog that the user can launch from the git-gui Options panel. The dialog offers the user a scrolling list of fonts in a pane. An example text shows the user what the font looks like at the size they have selected. But I have to admit the example pane is less than ideal. For example in the case of our diff font we really should show the user an example diff complete with our native diff syntax coloring. Signed-off-by: Shawn O.

2007-09-10Make --no-thin the default in git-push to save server resourcesLibravatar Shawn O. Pearce1-1/+1
1) pushes happen less often than fetches, so the bandwidth saving is much less visible in that case overall. 2) thin packs have to be complemented with missing delta bases to be valid, so many received thin packs will take more disk space. 3) the bother of repacking should be distributed amongst "clients" i.e. fetchers and pushers as much as possible, and not the server being fetched or pushed, to keep disk and CPU usage low on the server. This is why a fetch should get thin packs but a push should not. Both Nico and I have been assuming that --no-thin was the default behavior of git-push ever since Nico introduced --fix-thin into the index-pack process, which allowed fetch and receive-pack to avoid exploding packfiles received during transfer.

2007-09-09git-tag -s must fail if gpg cannot sign the tag.Libravatar Carlos Rica2-4/+21
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.

2007-09-09git-gui: Trim trailing slashes from untracked submodule namesLibravatar Shawn O. Pearce1-1/+5
Oddly enough `git ls-files --others` supplies us the name of an untracked submodule by including the trailing slash but that same git version will not accept the name with a trailing slash through `git update-index --stdin`. Stripping off that final slash character before loading it into our file lists allows git-gui to stage changes to submodules just like any other file.

2007-09-09git-gui: Avoid use of libdir in MakefileLibravatar Shawn O. Pearce1-3/+3
Dmitry V. Levin pointed out that on GNU linux libdir is often used in Makefiles to mean "/usr/lib" or "/usr/lib64", a directory that is meant to hold platform-specific binary files. Using a different libdir meaning here in git-gui's Makefile breaks idomatic expressions like rpm specifile "make libdir=%_libdir". Originally I asked that the git.git Makefile undefine libdir before it calls git-gui's own Makefile but it turns out this is very hard to do, if not impossible. Renaming our libdir to gg_libdir resolves this case with a minimum amount of fuss on our part. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
