 ## Profiling
 
-If you want to investigate what's contributing to CPU usage you can add the following to the top of the `main()` function in `main.go`
-
-```go
-import "runtime/pprof"
-
-func main() {
-	f, err := os.Create("cpu.prof")
-	if err != nil {
-		log.Fatal("could not create CPU profile: ", err)
-	}
-	defer f.Close()
-	if err := pprof.StartCPUProfile(f); err != nil {
-		log.Fatal("could not start CPU profile: ", err)
-	}
-	defer pprof.StopCPUProfile()
-	...
-```
-
-Then run lazygit, and afterwards, from your terminal, run:
-
-```sh
-go tool pprof --web cpu.prof
-```
-
-That should open an application which allows you to view the breakdown of CPU usage.
+If you want to investigate what's contributing to CPU or memory usage, see [this separate document](docs/dev/Profiling.md).

+# About the mechanics of lazygit's "Find base commit for fixup" command
+
+## Background
+
+Lazygit has a command called "Find base commit for fixup" that helps with
+creating fixup commits. (It is bound to "ctrl-f" by default, and I'll call it
+simply "the ctrl-f command" throughout the rest of this text for brevity.)
+
+It's a heuristic that needs to make a few assumptions; it tends to work well in
+practice if users are aware of its limitations. The user-facing side of the
+topic is explained [here](../Fixup_Commits.md). In this document we describe how
+it works internally, and the design decisions behind it.
+
+It is also interesting to compare it to the standalone tool
+[git-absorb](https://github.com/tummychow/git-absorb) which does a very similar
+thing, but made different decisions in some cases. We'll explore these
+differences in this document.
+
+## Design goals
+
+I'll start with git-absorb's design goals (my interpretation, since I can't
+speak for git-absorb's maintainer of course): its main goal seems to be minimum
+user interaction required. The idea is that you have a PR in review, the
+reviewer requested a bunch of changes, you make all these changes, so you have a
+working copy with lots of modified files, and then you fire up git-absorb and it
+creates all the necessary fixup commits automatically with no further user
+intervention.
+
+While this sounds attractive, it conflicts with ctrl-f's main design goal, which
+is to support creating high-quality fixups. My philosophy is that fixup commits
+should have the same high quality standards as normal commits; in particular:
+
+- they should be atomic. This means that multiple diff hunks that belong
+  together to form one logical change should be in the same fixup commit. (Not
+  always possible if the logical change needs to be fixed up into several
+  different base commits.)
+- they should be minimal. Every fixup commit should ideally contain only one
+  logical change, not several unrelated ones.
+
+Why is this important? Because fixup commits are mainly a tool for reviewing (if
+they weren't, you might as well squash the changes into their base commits right
+away). And reviewing fixup commits is easier if they are well-structured, just
+like normal commits.
+
+The only way to achieve this with git-absorb is to set the `oneFixupPerCommit`
+config option (for the first goal), and then manually stage the changes that
+belong together (for the second). This is close to what you have to do with
+ctrl-f, with one exception that we'll get to below.
+
+But ctrl-f enforces this by refusing to do the job if the staged hunks belong to
+more than one base commit. Git-absorb will happily create multiple fixup commits
+in this case; ctrl-f doesn't, to enforce that you pay attention to how you group
+the changes. There's another reason for this behavior: ctrl-f doesn't create
+fixup commits itself (unlike git-absorb), instead it just selects the found base
+commit so that the user can decide whether to amend the changes right in, or
+create a fixup commit from there (both are single-key commands in lazygit). And
+lazygit doesn't support non-contiguous multiselections of commits, but even if
+it did, it wouldn't help much in this case.
+
+## The mechanics
+
+### General approach
+
+Git-absorb uses a relatively simple approach, and the benefit is of course that
+it is easy to understand: it looks at every diff hunk separately, and for every
+hunk it looks at all commits (starting from the newest one backwards) to find
+the earliest commit that the change can be amended to without conflicts.
+
+It is important to realize that "diff hunk" doesn't necessarily mean what you
+see in the diff view. Git-absorb and ctrl-f both use a context of 0 when diffing
+your code, so they often see more and smaller hunks than users do. For example,
+moving a line of code down by one line is a single hunk for users, but it's two
+separate hunks for git-absorb and ctrl-f; one for deleting the line at the old
+place, and another one for adding the line at the new place, even if it's only
+one line further down.
+
+From this, it follows that there's one big problem with git-absorb's approach:
+when moving code, it doesn't realize that the two related hunks of deleting the
+code from the old place and inserting it at the new place belong together, and
+often it will manage to create a fixup commit for the first hunk, but leave the
+other hunk in your working copy as "don't know what to do with this". As an
+example, suppose your PR is adding a line of code to an existing function, maybe
+one that declares a new variable, and a reviewer suggests to move this line down
+a bit, closer to where some other related variables are declared. Moving the
+line down results in two diff hunks (from the perspective of git-absorb and
+ctrl-f, as they both use a context of 0 when diffing), and when looking at the
+second diff hunk in isolation there's no way to find a base commit in your PR
+for it, because the surrounding code is already on main.
+
+To solve this, the ctrl-f command makes a distinction between hunks that have
+deleted lines and hunks that have only added lines. If the whole diff contains
+any hunks that have deleted lines, it uses only those hunks to determine the
+base commit, and then assumes that all the hunks that have only added lines
+belong into the same commit. This nicely solves the above example of moving
+code, but also other examples such as the following:
+
+<details>
+<summary>Click to show example</summary>
+
+Suppose you have a PR in which you added the following function:
+
+```go
+func findCommit(hash string) (*models.Commit, int, bool) {
+	for i, commit := range self.c.Model().Commits {
+		if commit.Hash == hash {
+			return commit, i, true
+		}
+	}
+
+	return nil, -1, false
+}
+```
+
+A reviewer suggests to replace the manual `for` loop with a call to
+`lo.FindIndexOf` since that's less code and more idiomatic. So your modification
+is this:
+
+```diff
+--- a/my_file.go
++++ b/my_file.go
+@@ -12,2 +12,3 @@ import (
+ 	"github.com/jesseduffield/lazygit/pkg/utils"

++	return lo.FindIndexOf(self.c.Model().Commits, func(commit *models.Commit) bool {
++		return commit.Hash == hash
++	})
+ }
+```
+
+If we were to look at these two hunks separately, we'd easily find the base
+commit for the second one, but we wouldn't find the one for the first hunk
+because the imports around the added import have been on main for a long time.
+In fact, git-absorb leaves this hunk in the working copy because it doesn't know
+what to do with it.
+
+</details>
+
+Only if there are no hunks with deleted lines does ctrl-f look at the hunks with
+only added lines and determines the base commit for them. This solves cases like
+adding a comment above a function that you added in your PR.
+
+The downside of this more complicated approach is that it relies on the user
+staging related hunks correctly. However, in my experience this is easy to do
+and not very error-prone, as long as users are aware of this behavior. Lazygit
+tries to help making them aware of it by showing a warning whenever there are
+hunks with only added lines in addition to hunks with deleted lines.
+
+### Finding the base commit for a given hunk
+
+As explained above, git-absorb finds the base commit by walking the commits
+backwards until it finds one that conflicts with the hunk, and then the found
+base commit is the one just before that one. This works reliably, but it is
+slow.
+
+Ctrl-f uses a different approach that is usually much faster, but should always
+yield the same result. Again, it makes a distinction between hunks with deleted
+lines and hunks with only added lines. For hunks with deleted lines it performs
+a line range blame for all the deleted lines (e.g. `git blame -L42,+3 --
+filename`), and if the result is the same for all deleted lines, then that's the
+base commit; otherwise it returns an error.
+
+For hunks with only added lines, it gets a little more complicated. We blame the
+single lines just before and just after the hunk (I'll ignore the edge cases of
+either of those not existing because the hunk is at the beginning or end of the
+file; read the code to see how we handle these cases). If the blame result is
+the same for both, then that's the base commit. This is the case of adding a
+line in the middle of a block of code that was added in the PR. Otherwise, the
+base commit is the more recent of the two (and in this case it doesn't matter if
+the other one is an earlier commit in the current branch, or a possibly very old
+commit that's already on main). This covers the common case of adding a comment
+to a function that was added in the PR, but also adding another line at the end
+of a block of code that was added in the base commit.
+
+It's interesting to discuss what "more recent" means here. You could say if
+commit A is an ancestor of commit B (or in other words, A is reachable from B)
+then B is the more recent one. And if none of the two commits is reachable from
+the other, you have an error case because it's unclear which of the two should
+be considered the base commit. The scenario in which this happens is a commit
+history like this:
+
+```
+      C---D
+     /     \
+A---B---E---F---G
+```
+
+where, for instance, D and E are the two blame results.
+
+Unfortunately, determining the ancestry relationship between two commits using
+git commands is a bit expensive and not totally straightforward. Fortunately,
+it's not necessary in lazygit because lazygit has the most recent 300 commits
+cached in memory, and can simply search its linear list of commits to see which
+one is closer to the beginning of the list. If only one of the two commits is
+found within those 300 commits, then that's the more recent one; if neither is
+found, we assume that both commits are on main and error out. In the merge
+scenario pictured above, we arbitrarily return one of the two commits (this will
+depend on the log order), but that's probably fine as this scenario should be
+extremely rare in practice; in most cases, feature branches are simply linear.
+
+### Knowing where to stop searching
+
+Git-absorb needs to know when to stop walking backwards searching for commits,
+since it doesn't make sense to create fixups for commits that are already on
+main. However, it doesn't know where the current branch ends and main starts, so
+it needs to rely on user input for this. By default it searches the most recent
+10 commits, but this can be overridden with a config setting. In longer branches
+this is often not enough for finding the base commit; but setting it to a higher
+value causes the command to take longer to complete when the base commit can't
+be found.
+
+Lazygit doesn't have this problem. For a given blame result it needs to
+determine whether that commit is already on main, and if it can find the commit
+in its cached list of the first 300 commits it can get that information from
+there, because lazygit knows what the user's configured main branches are
+(`master` and `main` by default, but it could also include branches like `devel`
+or `1.0-hotfixes`), and so it can tell for each commit whether it's contained in
+one of those main branches. And if it can't find it among the first 300 commits,
+it assumes the commit already on main, on the assumption that no feature branch
+has more than 300 commits.

+# Profiling Lazygit
+
+If you want to investigate what's contributing to CPU or memory usage, start
+lazygit with the `-profile` command line flag. This tells it to start an
+integrated web server that listens for profiling requests.
+
+## Save profile data
+
+### CPU
+
+While lazygit is running with the `-profile` flag, perform a CPU profile and
+save it to a file by running this command in another terminal window:
+
+```sh
+curl -o cpu.out http://127.0.0.1:6060/debug/pprof/profile
+```
+
+By default, it profiles for 30 seconds. To change the duration, use
+
+```sh
+curl -o cpu.out 'http://127.0.0.1:6060/debug/pprof/profile?seconds=60'
+```
+
+### Memory
+
+To save a heap profile (containing information about all memory allocated so
+far since startup), use
+
+```sh
+curl -o mem.out http://127.0.0.1:6060/debug/pprof/heap
+```
+
+Sometimes it can be useful to get a delta log, i.e. to see how memory usage
+developed from one point in time to another. For that, use
+
+```sh
+curl -o mem.out 'http://127.0.0.1:6060/debug/pprof/heap?seconds=20'
+```
+
+This will log the memory usage difference between now and 20 seconds later, so
+it gives you 20 seconds to perform the action in lazygit that you are interested
+in measuring.
+
+## View profile data
+
+To display the profile data, you can either use speedscope.app, or the pprof
+tool that comes with go. I prefer the former because it has a nicer UI and is a
+little more powerful; however, I have seen cases where it wasn't able to load a
+profile for some reason, in which case it's good to have the pprof tool as a
+fallback.
+
+### Speedscope.app
+
+Go to https://www.speedscope.app/ in your browser, and drag the saved profile
+onto the browser window. Refer to [the
+documentation](https://github.com/jlfwong/speedscope?tab=readme-ov-file#usage)
+for how to navigate the data.
+
+### Pprof tool
+
+To view a profile that you saved as `cpu.out`, use
+
+```sh
+go tool pprof -http=:8080 cpu.out
+```
+
+By default this shows the graph view, which I don't find very useful myself.
+Choose "Flame Graph" from the View menu to show a much more useful
+representation of the data.
