Would you please strip for release assets?

[abcfy2]

I think you can strip for release assets so that thin the tar package.

[zonyitoo]

What do you mean? Release packages only contains executable binaries.

[abcfy2]

I mean that maybe we could use strip to reduce binaries size.

Example:

# Before strip
$ file sslocal
sslocal: ELF 64-bit LSB pie executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.6.32, BuildID[sha1]=54d3e530a75fc39515e4c4f56f439c61cbd6133b, with debug_info, not stripped  

$ du -h sslocal
11M     sslocal

# After strip
$ strip sslocal
$ file sslocal
sslocal: ELF 64-bit LSB pie executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.6.32, BuildID[sha1]=54d3e530a75fc39515e4c4f56f439c61cbd6133b, stripped

$ du -h sslocal
8.4M    sslocal

You can see after strip, sslocal file size reduced from 11M to 8.4M.

I am going to wait for cargo's strip option: rust-lang/cargo#3483 to be stablized.

Calling strip manually in build script may be nasty in cross builds.

Also, stripped binaries will not be able to show stacktrace when panicking. (But I have already set panic to be abort in release anyway.)

[zonyitoo]

cargo-features = ["strip"]

[profile.release]
strip = "symbols"

This will require a nightly build of cargo. I will keep this issue open until this feature is stablized.

strip with UPX on top? ;P

[xnoreq]

@Kein Why would you ever want to use UPX? To increase memory usage further because now it also needs to be uncompressed in memory?

Disabling trust-dns (which is not a performance problem for the client sslocal) and switching from log4rs to stderrorlog (who needs a full-blown logging framework for a socks client?) I get a Windows sslocal binary that's 2.7 MB vs the almost 9MB in the release.

I think this could be reduced further still, but would require going into the dependencies and patching them to make some of their dependencies optional.

I get a Windows sslocal binary that's 2.7 MB vs the almost 9MB in the release.

That is pretty sweet. Got a fork or PR?

[zonyitoo]

You could just build it without the trust-dns feature.
