2015-11-29Run go fmtJakob Unterwurzacher
2015-11-29Add single-element cache for DirIV lookupJakob Unterwurzacher
Another 3x performance boost for applications that walk the directory tree. Excerpt from performance.txt: VERSION UNTAR LS RM v0.4 48 1.5 5 v0.5-rc1 56 7 19 v0.5-rc1-1 54 4.1 9 v0.5-rc1-2 45 1.7 3.4 <---- THIS VERSION
2015-11-29OpenDir performance: Read DirIV once and reuse it for all namesJakob Unterwurzacher
Formerly, we called decryptPath for every name. That resulted in a directory walk that reads in all diriv files on the way. Massive improvement for RM and LS (check performance.txt for details) VERSION UNTAR RM LS v0.4 48 5 1.5 v0.5-rc1 56 19 7 v0.5-rc1-1 54 9 4.1 <---- THIS VERSION
2015-11-29Handle all operations except mounting without forking a childJakob Unterwurzacher
This saves 170ms for each start (why do we take 170ms to start up?) and cuts down test time by 2 seconds.
2015-11-29Add "-scryptn" option that sets the cost parameter for scryptv0.5-rc1Jakob Unterwurzacher
Use that option to speed up the automated tests by 7 seconds. Before: ok github.com/rfjakob/gocryptfs/integration_tests 26.667s After: ok github.com/rfjakob/gocryptfs/integration_tests 19.534s
2015-11-29tests: add scrypt benchmarkJakob Unterwurzacher
Times the impact of the parameter "N" to scrypt. Results on a 2.7GHz Pentium G630: gocryptfs/cryptfs$ go test -bench=.

2015-11-28tests: add v0.5 example filesystem (with DirIV!)Jakob Unterwurzacher
2015-11-28tests: verify that symlinks workJakob Unterwurzacher
2015-11-28diriv: also support old CBC symlinkJakob Unterwurzacher
2015-11-28diriv: fix Symlink() and Readlink()Jakob Unterwurzacher
Both were missing adaptions for diriv usage resulting in broken functionality
2015-11-28diriv: fix readdirJakob Unterwurzacher
It decrypted all file names using the root directory iv
2015-11-28diriv: use "DirIV" flag to discern and support mounting old filesystemsJakob Unterwurzacher
2015-11-27main: pass args struct instead of having a huge function callJakob Unterwurzacher
2015-11-27Run go fmtJakob Unterwurzacher
2015-11-27diriv: Define "DirIV" feature flagJakob Unterwurzacher
(unused so far)
2015-11-27tests: create all-zero gocryptfs.diriv in resetTmpDir()Jakob Unterwurzacher
Tests were failing because this file was missing
2015-11-27diriv: Move WriteDirIV() to cryptfs; add locking to Mkdir, RmdirJakob Unterwurzacher
2015-11-27diriv: Convert filename encryption users to dirivJakob Unterwurzacher
2015-11-25diriv: Transactionally delete gocryptfs.diriv in RmdirJakob Unterwurzacher
2015-11-25tests: check Mkdir and RmdirJakob Unterwurzacher
2015-11-25diriv: Create gocryptfs.diriv in every directoryJakob Unterwurzacher
2015-11-25Tighten file permissions on gocryptfs.confJakob Unterwurzacher
This file should only be readable by the owner and never be written to.
2015-11-25Print newline after gocryptfs.conf not found errorJakob Unterwurzacher
2015-11-22Add drone.io CI configJakob Unterwurzacher
2015-11-15README: link to use .../tags instead of ../releasesv0.4Jakob Unterwurzacher
Using github "release" function means that the changelog is buried in the github webinterface. The changelog is now instead included in README.md.
2015-11-15Update README for v0.4Jakob Unterwurzacher
Also, add short comments to the top of main_test.go and performance_test.go.
2015-11-15tests: add example_filesystems, test password and -masterkey mountJakob Unterwurzacher
2015-11-15CipherSizeToPlainSize: Handle illegal statesJakob Unterwurzacher
A file never gets a cipherSize <= HEADER_LEN in normal operation. However, this can happen if header write it interrupted or the underlying filesystem does not support fallocate. Noticed while trying to store a CIPHERDIR in another gocryptfs mount (gocryptfs does not support fallocate)
2015-11-15Move "Debug output enabled" after forkChild() to remove duplicate outputJakob Unterwurzacher
2015-11-15tests: add tests for "-config" optionJakob Unterwurzacher
2015-11-15Add "-extpass" cli option and associated testsJakob Unterwurzacher
2015-11-14MANPAGE: add "-config" flagJakob Unterwurzacher
Also, "-plaintextnames" can be used with -zerokey. Fix the incorrect description.
2015-11-14Refactor cli argument handlingJakob Unterwurzacher
Also, add the "-config" option for storing gocryptfs.conf outside of CIPHERDIR.
2015-11-14README: add beta badge and update textJakob Unterwurzacher
Also, improve the help text.
2015-11-14README: add beta badgeJakob Unterwurzacher

2015-11-12tests: move integration tests to separate directoryJakob Unterwurzacher
Also, use new "-defaultonly" flag for benchmarks (only tests with openssl=true plaintextnames=false)
