[PATCH] openssl: add OP_NO_COMPRESSION constant
Added by normalperson (Eric Wong) about 13 years ago.
Updated about 13 years ago.
Description
Disabling OpenSSL compression can save memory since zlib buffers
enforce a rather large per-connection overhead. For
memory-constrained systems that have OpenSSL built against zlib,
there can be a drastic reduction in memory usage with 1000 open
connections:
Compression enabled
VmRSS: 596132 kB
Compression disabled
VmRSS: 21924 kB
The above was generated with openssl 1.0.0.d-3 on Debian testing
(x86_64). The NOCOMP environment variable controls compression
in the attached script.
If you prefer: git pull git://bogomips.org/ruby openssl-no-compression

Eric, thank you for reporting this issue.
Your contribution to Ruby is greatly appreciated.
May Ruby be with you.
- ext/openssl/ossl_ssl.c: Support disabling OpenSSL compression.
- test/openssl/test_ssl.rb: Add a test for it.
Thanks to Eric Wong for the patch.
[Ruby 1.9 - Feature #5183] [ruby-core:38911]
- Target version changed from 2.0.0 to 1.9.3
I can only repeat what Motohiro said the other day - thanks a lot
for your contribution, Eric!
I also backported this to 1.9.3, as I can only see benefit in this
patch.
It shouldn't affect the stability of 1.9.3. But please object if
anyone thinks different, then I would revert the commit right away.
