the static type analysis tool we use - uses the `typing` module, which +provides core functionality fundamental to mypy's functioning. + +Generally, `typing` would be imported at runtime and used in that fashion - +it acts as a no-op at runtime and does not have any run-time overhead by +design. + +As it turns out, `typing` is not vendorable - it uses separate sources for +Python 2/Python 3. Thus, this codebase can not expect it to be present. +To work around this, mypy allows the typing import to be behind a False-y +optional to prevent it from running at runtime and type-comments can be used +to remove the need for the types to be accessible directly during runtime. + +This module provides the False-y guard in a nicely named fashion so that a +curious maintainer can reach here to read this. + +In pip, all static-typing related imports should be guarded as follows: + + from pip._internal.utils.typing import MYPY_CHECK_RUNNING + + if MYPY_CHECK_RUNNING: + from typing import ... + +Ref: https://github.com/python/mypy/issues/3216 +""" + +MYPY_CHECK_RUNNING = False + + +if MYPY_CHECK_RUNNING: + from typing import cast +else: + # typing's cast() is needed at runtime, but we don't want to import typing. + # Thus, we use a dummy no-op version, which we tell mypy to ignore. + def cast(type_, value): # type: ignore + return value diff --git a/.env/lib/python2.7/site-packages/pip/_internal/utils/typing.pyc b/.env/lib/python2.7/site-packages/pip/_internal/utils/typing.pyc new file mode 100644 index 0000000000000000000000000000000000000000..e34528332080d4e048817e6881260d5eaa76aa59 GIT binary patch literal 1641 zcmc&!O^@3)5T(8DHWkoId+ddmpnI@IbOW@&qA1!fnlvbC1l!Fad#IPD#ugii6iCXh zfF66z@5~R#4@loo%I50_RIp@;9KLz;=8-3_J}+Lpc=@Lh(>2HckGSJG9+eO`LeNay z%mvLwxG$=isOF+M5$!_UEX2%xCaM$hFX9%WT8KZ+KH;@LFNApLgLI@*Gf3NZ4YlNw zb$c0;PS(gYbo^zV>}*#S#cexu!>wG&RMR^#B(>Ac5N(vn`$ir~_K^^VCx#GvJ0ji6 z)>nN)OL?rVsf#Z7gRKx_d?2~&ok`XM%BF$8D$RU!160YGzm9h?panjU$WhQuGc4a` zIQqV+nO|usm1O%Y#y0*L_@~2w)js(N;roqg@83zdJH1XZI{c7brr>vbgs0 z=)-fVgNM9%^)gEwRqbym>X?v_DF#|Q|Dbi+9qm1<%n`Szgf$w%cH{qfvB(5wa@4F4M zQ^2+;`(&F~zTcnUpFMfDx%~B)%ilIvPuJ_m>qp~qyOSSJU1a1t^!Jg<5+z*G?n2fn zb@4)}y-jt$EzvX8Wd|zWhRVj+Q&bPmzxlSXuW_BtaG)fdC&K8M3?EN?^XMh+$TR=U zaPaWR`V0?o#sP^BBJS`eza4bb(>Ti^G2x+}Mha1}eQVnU#rBPzHl)zpzuKbbfkrI{R|* EAI!N6=buy+v+sf9!{; zTv~CsehL>OM`|n>f=%lI`^;HrwvW4BJIEvdRLFZ8j=$*b}tc=)^Ur z9vcIZ+B8AG3P53qd{qF@Y>l^uOCwkj?uiNV)ky~ZHi8I3yi*dw+&11Figc0AzR@Tz zfrrTa+{tlyoMncOPF+Gj^z*cWbZs$y$*Q)G1Xo$_rk+}&JZcV4ELP6JLXjgT{6;Wp zACq7=YUdLV`bxyuGF97ySR5GsCndk3SJ}iNCdTrJ2G@_`2q?zSNlsC<5)e4yLnzp74uVm|K(sdEB*P%A?cr_sQZu-H; zr2WCcu75*ryn|Nt*3hbWB99Yrlzq#C%x>4_DjAWTpTV9X1ZQ32GP!XZVR<{x_5>q> z&a~IwBtt4Kqt>BnWsbE5`)CfxqTS+S|A2_SaNUACK_* z-hb2WuPc#M3-3{KuM!0;h5<=O;@Z`UnOvrteiW9AkJ4QZm|8cual_Dt!NIlsH$1#! zurK+qf3Sb>K4NWqhDV0i46h#?8tm)MZ5SFHB%d?*hbIziQ0XPdfI@{wUZq<_ds(*sWa}!k9!$pMR zgb74y@O#Jfs4}kOG)k6WQ7N;wK>MstH%Xf81V-{nVt=60xS8TAt>1|WYF+0dLzna` z3zP;+i3M%jW8}#~`ywEeu%ntTC_v$3s9W4%D&XIP+3*Kqi^&N_AxiYR0w*n+jaC?R z*J~D!Et~@pe2bEvp5+xlZ-FUvpA+j75|rC98IM0hTi=;j2Dr02kwm8obzphE&36in z_5GGJuLNtvUGAszy8Q`~)j%N{{=4c9 z9gYd&3@r+hG!sUMo43Hc4&v~Pyccm4qC{VcI4(fke0C1ya>Pkt54GeH?o;xex)qi} zp*S26BN`Wyy#w|UGI4&qlVpj6x4@ZIEZY^p<2OfrrAS`wQu>EG(qXxj zuKaKQy?26r4H$H@*q5JR^U31yZKQL)Gp%0FFPlxJZifc(uaK=ezD)Emf;Gwut4kVd z7@rlq&3CC;G2th^0%#tuagDfRL6{&`rBx$?H3|NZMv%zh+~Bayi6uH||9I{-z3p7w zR?|bfld!NOd6w{gOIpsCQ0#ETf0cAs`r>p~>d;+BohvOPK&f-K&TC!!%f$P-V3KgdNl3F6gb@eGpEUz5`} z*^7rYv_;$Hv`;F2KS}1HJ#Xvb9cv=Ef`uC-C$s27&GN0=ryAl0pOaws*G#*b`P)0o z=J8%yeQoramyfZbgbkce%lhS8Hb)O1R;J(8`SkeyvHR_Ox!3f)o69#3jPch5*K3!@ zyR$Z{wab^fvM%crIrfQ}*DjY2+;4`rzVwt@J~e9iO~W&@X{HJ6(#)()HL~J(3_6O_Pw&s(vZ|i&KEF?O47+2UZ%=>6WZ3e^pUX+A+MYXeVHEq zeoDjoD3lFcGoJcx1OG!VkWFZ`o@D(t1T3eQu#3jrZjA1^af3 zZCN6gef#4oyxGo}!hV8?v5EWKh3ncB$;XJ;xA1Z8TM$sw#&Tc;t0^l?*^B%xkjL2u zuTs%(c=$a#+knjuYqVm48Gqkp8s}Rxe7GIfpat+XpzwHkN%#!950~%ZW9ArQN{5ub zm7M;OtzuUheMb6<9SWnkQRVasf2O@1G~^v&`jm@Y&#Z@XRzABV`GQ`fiQ|Q3sO)ss zB~8Wly^jt@So06^!U{isViDU7K!Y8?%mRpi^Io}Z;z@tZ|HC{t@0PX({ zI8&RG{NenklrQp+@J4ZY#cpn_0ur}Ssswa@Bud{+|FoX6fdzL3A+6`H4(}hyZ6~T?
