|
381
|
** About This Feature |
|
382
|
** ================== |
|
383
|
** |
|
384
|
** On some ssh servers (Macs in particular are guilty of this) the PATH |
|
385
|
** variable in the shell that runs the command that is sent to the remote |
|
386
|
** host contains a limited number of read-only system directories: |
|
387
|
** |
|
388
|
** /usr/bin:/bin:/usr/sbin:/sbin |
|
389
|
** |
|
390
|
** The fossil executable cannot be installed into any of those directories |
|
391
|
** because they are locked down, and so the "fossil" command cannot run. |
|
392
|
** |
|
393
|
** To work around this, the fossil command is prefixed with the PATH= |
|
394
|
** argument, inserted by this function, to augment the PATH with additional |
|
395
|
** directories in which the fossil executable is often found. |
|
396
|
** |
|
397
|
** But other ssh servers are confused by this initial PATH= argument. |
|
398
|
** Some ssh servers have a list of programs that they are allowed to run |
|
399
|
** and will fail if the first argument is not on that list, and PATH=.... |
|
400
|
** is not on that list. |
|
401
|
** |
|
402
|
** So that various commands that use ssh can run seamlessly on a variety |
|
403
|
** of systems (commands that use ssh include "fossil sync" with an ssh: |
|
404
|
** URL and the "fossil patch pull" and "fossil patch push" commands where |
|
405
|
** the destination directory starts with HOSTNAME: or USER@HOSTNAME:.) |
|
406
|
** the following algorithm is used: |
|
407
|
** |
|
408
|
** * First try running the fossil without any PATH= argument. If that |
|
409
|
** works (and it does on a majority of systems) then we are done. |
|
410
|
** |
|
411
|
** * If the first attempt fails, then try again after adding the |
|
412
|
** PATH= prefix argument. (This function is what adds that |
|
413
|
** argument.) If the retry works, then remember that fact using |
|
414
|
** the use-path-for-ssh:HOSTNAME setting so that the first step |
|
415
|
** is skipped on subsequent uses of the same command. |
|

1014

** |

|
** Send an HTTP message to URL and get the reply. PAYLOAD is a file containing |
|
1016
|
** the payload, or "-" to read payload from standard input. A POST message |
|
1017
|
** is sent if PAYLOAD is specified and is non-empty. If PAYLOAD is omitted |
|
1018
|
** or is an empty file, then a GET message is sent. |
|
1019
|
** |
|
1020
|
** If a second filename (OUTPUT) is given after PAYLOAD, then the reply |
|
1021
|
** is written into that second file instead of being written on standard |
|
1022
|
** output. Use the "--out OUTPUT" option to specify an output file for |
|
1023
|
** a GET request where there is no PAYLOAD. |
|
1024
|
** |
|
1025
|
** Options: |
|
1026
|
** --compress Use ZLIB compression on the payload |
|
1027
|
** --mimetype TYPE Mimetype of the payload |
|
1028
|
** --no-cert-verify Disable TLS cert verification |
|
1029
|
** --out FILE Store the reply in FILE |
|
1030
|
** --subpath PATH HTTP request path for ssh: and file: URLs |
|
1031
|
** -v Verbose output |
|
1032
|
** --xfer PAYLOAD in a Fossil xfer protocol message |
