The previous behaviour was designed to mimic the output buffering of
typical UNIX tools: line-buffered if stdout is a TTY, and fully-buffered
otherwise. More precicely, when printing to a terminal, fd would flush
explicitly after printing any buffered results, then flush after every
single result once streaming mode started. When not printing to a
terminal, fd never explicitly flushed, so writes would only happen as
the BufWriter filled up.
The new behaviour actually unifies the TTY and non-TTY cases: we flush
after printing the buffered results, then once we start streaming, we
flush after each batch, but *only when the channel is empty*. This
provides a good balance: if the channel is empty, the receiver thread
might as well flush before it goes to sleep waiting for more results.
If the channel is non-empty, we might as well process those results
before deciding to flush.
For TTYs, this should improve performance by consolidating write() calls
without sacrificing interactivity. For non-TTYs, we'll be flushing more
often, but only when the receiver would otherwise have nothing to do,
thus improving interactivity without sacrificing performance. This is
particularly handy when fd is piped into another command (such as head
or grep): with the old behaviour, fd could wait for the whole traversal
to finish before printing anything. With the new behaviour, fd will
print those results soon after they are received.
Fixes#1313.
Summary: Currently, `--ignore-vcs` only serves to unset `--no-ignore-vcs`.
There is currently no way to tell fd to respect gitignore files when not in a
git repository. This commit adds the flag `--no-require-git` to make fd always
respect all gitignore files.
This behaves the same as the `--no-require-git` option in [ripgrep](3bb71b0cb8/crates/core/app.rs (L2214-L2226))
This commit also contains an unrelated wording fix to CONTRIBUTING.md
Test Plan: `tests/tests.rs`
Background: I am using [Sapling](https://sapling-scm.com/docs/introduction/)
for working with git repositories (including this commit ☺️). Since Sapling
uses `.sl` instead of `.git`, tools using the `ignore` crate (rg and fd) would show gitignored files.
I made a patch (ebf17eef22)
to `ignore` to respect gitignores with _either_ `.git` or `.sl`. However,
@BurntSushi said he did not want to merge that patch and instead suggested I
use `--no-require-git` (https://github.com/BurntSushi/ripgrep/issues/2374).
This works fine, but I couldn't use this workaround for my other favorite tool!
That's what this patch is for 😁
(a follow-up patch will add a similar `FD_CONFIG_PATH` environment variable
like `RG_CONFIG_PATH`)
Make sure that using `--no-ignore-vcs` or `--no-ignore` don't also
enable `--no-ignore-parent`. So that if `--no-ignore-vcs` is enabled, it
continues to respect .fdignore and .ignore in the parent directories.
Fixes: #907Fixes: #901
quit_flag is now used to quit the sender threads for any reason, either
due to an interrupt or because the receiver is done.
interrupt_flag is used specifically for ^C interrupts, and causes the
receiver to stop between printing paths, to avoid unfinished escape
sequences when colors are being used.
Fixes#867.
The new ReceiverBuffer struct allows us to factor out the receiver
implementation into a number of helper methods. The new implementation
uses rx.{recv,recv_timeout} instead of a for loop, which enables us to
switch to streaming mode at the right time without waiting for more
results.
Fixes#868.
