python libarchive to get mtime of the archive -


i have python libarchive 0.4.3 installed. i'd mtime of 7z file stored inside 7z file. different mtime of file stored locally on disk. let's underlying source c tarball lzma1604.7z.

the following program list of files , mtime of that. don't see time entire 7z "tarball" given in 7z file. 

from libarchive.public import memory_reader open('lzma1604.7z', 'rb') f:     buffer = f.read()      memory_reader(buffer) archive:         entry in archive:             print(entry.pathname, entry.mtime)

the above program prints: 

('asm/arm/7zcrcopt.asm', datetime.datetime(2009, 10, 8, 5, 12)) ('asm/x86/7zasm.asm', datetime.datetime(2012, 12, 30, 3, 41, 54)) ... ('bin/7zsd.sfx', datetime.datetime(2016, 10, 4, 11, 12, 31)) ('bin/lzma.exe', datetime.datetime(2016, 10, 4, 11, 12, 30)) ('bin/x64/7zr.exe', datetime.datetime(2016, 10, 4, 10, 58, 29))

but if run 7z l lzma1604.7z gives @ end:

2016-10-04 10:12:31 ....a       113152               bin/7zsd.sfx 2016-10-04 10:12:30 ....a        97280               bin/lzma.exe 2016-10-04 09:58:29 ....a       742400               bin/x64/7zr.exe ------------------- ----- ------------ ------------  ------------------------ 2016-10-04 10:27:55            4534441       960121  620 files

so how in python via libarchive information, specifically, mtime of overall archive?

How to get the arclen between two curve points in Maya? -

in maya 2015, can arclen of curve using command: cmds.arclen('bezier1') but want arclen of 2 points in curve. there anyway this? using maya's api surely best way @scottiedoo said, here function made when didn't know api , gives same results. from maya import cmds def computecrvlength(crv, startparam = none, endparam = none): ''' compute length of curve between 2 given uparameters. if both uparameters arguments set none (default), compute length of whole curve. arguments: - crv = string; existing nurbcurve - startparam = 0 <= float <= 1 or none; default = none; point parameter value, if not none, compute points between startpt , endpt values. - endparam = 0 <= float <= 1 or none; default = none; point parameter value, if not none, compute points between startpt , endpt values. returns: - length of curve between given uparameters - length of curve start startp...

git svn - Unignore directories in git-svn (adding directories to a sparse checkout) -

when using git svn, sparse checkout of central repository may achieved along lines of git clone -s url-to-root --include-paths 'dir1|dir2|dir3' after using setup time, add directory dir4 tracked. directory has existed in many commits have checked out. editing variable svn-remote.svn.include-paths running git config --edit does not have desired effect on git fetch (only files changed in future commits checked out changed; not immediately), , following not check out dir4: git svn fetch --include-paths dir4 i think following work ineffective due refetching revisions since first revision @ dir4 appeared first time (let's call rev): git svn reset -r rev git svn fetch --include-paths dir4 git svn rebase what better way of tracking dir4? if not care history of dir4? is there better way initial sparse checkout git-svn if suspect want change list of tracked directories later? have tried starting listing directoreis not fetched in original commit, not know how...
