2007-09-26git-gui: Make the status bar easier to read in the setup wizardShawn O. Pearce
The setup wizard looks better if we layout the progress bar as two lines: the first line holds the message text and our text formatting of the progress while the second line holds the bar itself. Both extend the full width of the window and we try to pad out the message text so the window doesn't expand when the completed progress number jumps to the next order of magnitude. This change required updating the progress meter format string to allow the application to supply the precision. So we also are updating all of the translations at once to use the newer formatting string. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
2007-09-26git-gui: Switch the git-gui logo to Henrik Nyh's logoShawn O. Pearce
Henrik came up with this alternative logo for gitweb and posted it on his blog: http://henrik.nyh.se/2007/06/alternative-git-logo-and-favicon The msysGit port uses his logo within some of their components, and frankly it looks better here in git-gui for our repository setup wizard screen. The logo fits quite nicely along the left edge of our window, leaving significantly more vertical space for things like the git-fetch console output. Because the logo changes the layout charateristics of the setup window I also needed to adjust some of the padding for our widgets and stop using a fixed width window size. We now let Tk compute the correct size of the main window whenever the layout changes, and drop the window into roughly the upper left 1/3 of the desktop so its not quite centered but is likely to be far enough away from any sort of task bars/menu bars/docks that the user may have along any edge of the screen.

2007-09-26git-gui: Don't delete scrollbars in console windowsShawn O. Pearce
If we have added a scrollbar to the console window because one direction has too much text to fit in the available screen space we should just keep the scrollbars. Its annoying to watch our horizontal scrollbar bounce in and out of the window as additional text is inserted into the widget and the need for the scrollbar comes and goes. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
2007-09-26git-gui: Don't delete console window namespaces too earlyShawn O. Pearce
If the console finishes displaying its output and is "done" but needs to draw a scrollbar to show the final output messages it is possible for Tk to delete the window namespace before it does the text widget updates, which means we are unable to add the horizontal or vertical scrollbar to the window when the text widget decides it cannot draw all glyphs on screen. We need to delay deleting the window namespace until we know the window is not going to ever be used again. This occurs if we are done receiving output, the command is successful and the window is closed, or if the window is open and the user chooses to close the window after the command has completed.

2007-09-25git-gui: Copy objects/info/alternates during standard cloneShawn O. Pearce
If the source repository is using an objects/info/alternates file we need to copy the file to our new repository so that it can access any objects that won't be copied/hardlinked as they are stored in the alternate location. We explicitly resolve all paths in the objects/info/alternates as relative to the source repository but then convert them into an absolute path for the new clone. This allows the new clone to access the exact same locaton as the source repository, even if relative paths had been used before. Under Cygwin we assume that Git is Cygwin based and that the paths in objects/info/alternates must be valid Cygwin UNIX paths, so we need to run `cygpath --unix` on each line in the alternate list.

2007-09-25git-gui: Keep the UI responsive while counting objects in cloneShawn O. Pearce
If we are doing a "standard" clone by way of hardlinking the objects (or copying them if hardlinks are not available) the UI can freeze up for a good few seconds while Tcl scans all of the object directories. This is espeically noticed on a Windows system when you are working off network shares and need to wait for both the NT overheads and the network. We now show a progress bar as we count the objects and build our list of things to copy. This keeps the user amused and also makes sure we run the Tk event loop often enough that the window can still be dragged around the desktop. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
2007-09-25git-gui: Don't bother showing OS error message about hardlinksShawn O. Pearce
If we failed to create our test hardlink for the first object we need to link/copy then the only recourse we have is to make a copy of the objects. Users don't really need to know the OS details about why the hardlink failed as its usually because they are crossing filesystem boundaries. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>

2007-09-23git-gui: Avoid console scrollbars unless they are necessaryShawn O. Pearce
We shouldn't create scrollbars for the horziontal or vertical sides unless there is enough content to make it worth drawing these widgets on screen. This way users don't loose screen space to objects that won't help them navigate the display. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
2007-09-23git-gui: Allow users to choose/create/clone a repositoryShawn O. Pearce
If we are started outside of a git repository than it is likely the user started us from some sort of desktop shortcut icon in the operating system. In such a case the user is expecting us to prompt them to locate the git repository they want to work on, or to help them make a new repository, or to clone one from an existing location. This is a very simple wizard that offers the user one of these three choices. When we clone a repository we always use the name `master` in the local repository, even if the remote side does not appear to point to that name. I chose this as a policy decision. Much of the Git documentation talks about `master` being the default branch in a repository and that's what git-init does too. If the remote side doesn't call its default branch `master` most users just don't care, they just want to use Git the way the documentation describes. Rather than relying on the git-clone Porcelain that ships with git we build the new repository ourselves and then obtain content by git-fetch. This technique simplifies the entire clone process to roughly: `git init && git fetch && git pull`. Today we use three passes with git-fetch; the first pass gets us the bulk of the objects and the branches, the second pass gets us the tags, and the final pass gets us the current value of HEAD to initialize the default branch. If the source repository is on the local disk we try to use a hardlink to connect the objects into the new clone as this can be many times faster than copying the objects or packing them and passing the data through a pipe to index-pack. Unlike git-clone we stick to pure Tcl [file link -hard] operation thus avoiding the need to fork a cpio process to setup the hardlinks. If hardlinks do not appear to be supported (e.g. filesystem doesn't allow them or we are crossing filesystem boundaries) we use file copying instead. Signed-off-by: Shawn O.

* maint: git-gui: Disable native platform text selection in "lists" Conflicts: lib/browser.tcl
2007-09-17git-gui: Disable native platform text selection in "lists"gitgui-0.8.3Shawn O. Pearce
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>
2007-09-14git-gui: Paper bag fix missing translated stringsShawn O. Pearce
The Tcl expression "[append [mc Foo] Bar]" does not return the string "FooBar" after translation; instead it is setting the variable Foo to the value Bar, or if Foo is already defined it is appending Bar onto the end of it. This is *not* what we wanted to have happen here. Tcl's join function is actually the correct function but its default joinStr argument is a single space. Unfortunately all of our call sites do not want an extra space added to their string. So we need a small wrapper function to make the call to join with an empty join string. In C this is (roughly) the job of the strcat function. Since strcat is not yet used at the global level it is a reasonable name to use here. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
2007-09-14git-gui: Make the tree browser also use lightgray selectionShawn O. Pearce
In 9adccb05 Matthijs Melchior changed our selection colors in the main index/working directory file lists to use a lightgray as the background color as this made the UI easier to read on all platforms.

The recent bug fix to correctly handle filenames with %s (or any other valid Tcl format specifier) missed a \ on this line and caused the remaining format arguments to not be supplied when we updated the status bar.

2007-09-13git-gui: Font chooser to handle a large number of font familiesShawn O. Pearce
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.

2007-09-10git-gui: Localize commit/author dates when displaying themShawn O. Pearce
Currently the Git plumbing is not localized so it does not know how to output weekday and month names that conform to the user's locale preferences. This doesn't fit with the rest of git-gui's UI as some of our dates are formatted in Tcl and some are just read from the Git plumbing so dates aren't consistently presented. Since git-for-each-ref is presenting us formatted dates and it offers no way to change that setting even in git 1.5.3.1 we need to first do a parse of the text strings it produces, correct for timezones, then reformat the timestamp using Tcl's formatting routines. Not exactly what I wanted to do but it gets us consistently presented date strings in areas like the blame viewer and the revision picker mega-widget's tooltips. Signed-off-by: Shawn O.

2007-09-10git-gui: Assume untracked directories are Git submodulesShawn O. Pearce
If `git ls-files --others` returned us the name of a directory then it is because Git has decided that this directory itself contains a valid Git repository and its files shouldn't be listed as untracked for this repository.

If the user tried to detach their HEAD while keeping the working directory on the same commit we actually did not completely do a detach operation internally.

2007-08-20git-gui: Allow git-merge to use branch names in conflict markersShawn O. Pearce
Earlier when I rewrote the merge implementation for git-gui I broke it such that the conflict markers for the "theirs" side of the hunk was using a full SHA-1 ID in hex, rather than the name of the branch the user had merged. This was because I got paranoid and passed off the full SHA-1 to git-merge, instead of giving it the reference name the user saw in the merge dialog. I'd still like to resolve the SHA-1 upfront in git-gui and always use that value throughout the merge, but I can't do that until we have a full implementation of git-merge written in Tcl. Until then its more important that the conflict markers be useful to the end-user, so we need to pass off the ref name and not the SHA-1 ID. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>

cehteh on #git noticed that secondary windows such as console windows from push/fetch/merge or the blame browser failed on ion when we tried to open them a second time. The issue turned out to be the fact that on ion [winfo ismapped .] returns false if . is not visible right now because it has been obscured by another window in the same panel. So we need to keep track of whether or not the root window has been displayed for this application, and once it has been we cannot ever assume that ismapped is going to return true.

This is a replacement of all of the icons in our tree browser window, as the prior icons just looked too 1980s Tk-ish. The icons used here are actually from a KDE themed look, so they might actually be familiar to some users of git-gui. Aside from using more modern looking icons we now have a special icon for executable blobs, to make them stand out from the normal non-executable blobs. We also denote symlinks now with a different icon, so they stand out from the other types of objects in the tree. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
2007-07-30git-gui: Make sure remotes are loaded when picking revisionsShawn O. Pearce
If we are started for only a blame/browser/citool run we don't usually initialize the list of remotes, or determine which refs are tracking branches and which are local branch heads. This is because some of that work is relatively expensive and is usually not going to be needed if we are started only for a blame, or to make a single commit. However by not loading the remote configuration we were crashing if the user tried to open a browser for another branch through the Repository menu, as our load_all_heads procedure was unable to decide which refs/heads/ items were actually local heads. We now force all remote configuration data to be loaded if we have not done so already and we are trying to create a revision mega widget. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>

2007-07-25git-gui: Remove usernames from absolute SSH urls during mergingShawn O. Pearce
If we are being asked to merge a tracking branch that comes from a remote repository accessed by the very common SSH URL format of "user@host:/path/to/repo" then we really don't need the username as part of the merge message, it only clutters up the history and makes things more confusing. So we instead clip the username part off if the local filesystem path is absolute, as its probably not going to be an ambiguous URL even when it is missing the username. On the other hand we cannot clip the username off if the URL is not absolute, because in such cases (e.g. "user@host:myrepo") the directory that the repository path is resolved in is relative to the user's home directory, and the username becomes important.

2007-07-25git-gui: Format tracking branch merges as though they were pullsShawn O. Pearce
If we are merging a tracking branch we know exactly what remote URL that branch is fetched from, and what its name is on that remote repository. In this case we can setup a merge message that looks just like a standard `git-pull $remote $branch` operation by filling out FETCH_HEAD before we start git-merge, and then run git-merge just like git-pull does. I think the result of this behavior is that merges look a lot nicer when the came off of local tracking branches, because they no longer say "commit 'origin/...'" to describe the commit being merged but instead now mention the specific repository we fetched those commits from.

Now that we only support merging one branch we can offer the user a better user interface experience by allowing them to select the revision they want to merge through our revision picking widget.

2007-07-25git-gui: Show ref last update times in revision chooser tooltipsShawn O. Pearce
If we can we now show the last modification date of a loose ref as part of the tooltip information shown in the revision picker. This gives the user an indication of when was the last time that the ref was modified locally, and may especially be of interest when looking at a tracking branch. If we cannot find the loose ref file than we try to fallback on the reflog and scan it for the date of the last record. We don't start with the reflog however as scanning it backwards from the end is not an easy thing to do in Tcl. So I'm being lazy here and just going through the entire file, line by line. Since that is less efficient than a single stat system call, its our fallback strategy. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
2007-07-25git-gui: Display commit/tag/remote info in tooltip of revision pickerShawn O. Pearce
Our revision chooser mega-widget now sets up tooltips for itself so that it displays details about a commit (or a tag and the commit it refers to) when the user mouses over that line in the filtered ref list. If the item is from a remote tracking branch then we also show the remote url and what branch on that remote we fetch from, so the user has a clear concept of where that revision data originated. To help the merge dialog I've also added a new constructor that makes the dialog only offer unmerged revisions (those not in HEAD), as this allows users to avoid performing merges only to get "Already up to date" messages back from core Git.

2007-07-23git-gui: Avoid unnecessary symbolic-ref call during checkoutShawn O. Pearce
If we are checking out the branch we are already on then there is no need to call symbolic-ref to update the HEAD pointer to the "new" branch name, it is already correct. Currently this situation does not happen very often, but it can be seen in some workflows where the user always recreates their local branch from a remote tracking branch and more-or-less ignores what branch he/she is on right now. As they say, ignorance is bliss. This case will however become a tad more common when we overload checkout_op to actually also perform all of our merges. In that case we will likely see that the branch we want to "checkout" is the current branch, as we are actually just merging into it. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
2007-07-23git-gui: Paper bag fix quitting crash after commitShawn O. Pearce
My earlier introduction of the GITGUI_BCK file (which saves the user's commit message buffer while they are typing it) broke the Quit function. If the user makes a commit we delete the GITGUI_BCK file; if they then immediately quit the application we fail to rename the GITGUI_BCK file to GITGUI_MSG. This is because the file does not exist, but our flag still says it does. The root cause is we did not unset the flag during commit. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
2007-07-22git-gui: Fix unnecessary fast-forward during checkoutShawn O. Pearce
If we are trying to checkout a local branch which is matched to a remote tracking branch, but the local branch is newer than the remote tracking branch we actually just want to switch to the local branch. The local branch is "Already up to date". Unfortunately we tossed away the local branch's commit SHA-1 and kept the remote tracking branch's SHA-1, which meant that the user lost the local changes when we updated the working directory. At least we did not update the local branch ref, so the user's data was still intact. We now toss the tracking branch's SHA-1 and replace with the local branch's SHA-1 before the checkout, ensuring that we pass of the right tree to git-read-tree when we update the working directory.

2007-07-21git-gui: Internally allow fetch without storing for future pull supportShawn O. Pearce
This is actually just an underlying code improvement that has no user visible component yet. UI improvements to actually fetch and merge via an arbitrary remote with no tracking branches must still follow to make this change useful for the end-user. Our tracking branch specifications are a Tcl list of three components: - local tracking branch name - remote name/url - remote branch name/tag name This change just makes the first element optional. If it is an empty string we will run the fetch, but have the value be saved only into the special .git/FETCH_HEAD, where we can pick it up and use it for this one time operation.
